Basith, Abdul
Sazali, Munawir
Laju pertumbuhan penduduk Kota Malang sejak tahun 2001 semakin meningkat seiring dengan perkembangan perekonomian, pemukiman, pendidikan, dan budaya. Peningkatan laju pembangunan mengakibatkan peningkatan alih fungsi lahan, khususnya area RTH. Selain itu, peranan ecological services terus mengalami gradasi sehingga menyebabkan penurunan kenyamanan warga. Penelitian komparasional ini dilakukan pada tiga kelurahan, yaitu Kelurahan Jatimulyo, Kelurahan Mojolangu, dan Kelurahan Mergosono. Penentuan titik lokasi penelitian dan titik koordinat dengan memanfaatkan program Google Maps. Berdasarkan pada penghitungan naturalness index dan indeks kualitas biodiversitas kelurahan dengan nilai kealamian (naturalness) dan kualitas biodiversitas tertinggi adalah Kelurahan Jatimulyo, sedangkan yang terendah adalah Kelurahan Mergosono. Kontribusi naturalness index dan indeks kualitas biodiversitas terhadap suhu adalah 67% dan 82,86% dengan persamaan regresi y=33,621– 3,6686x dan y=31,138-0,0054x. Kontribusi naturalness index dan indeks kualitas biodiversitas terhadap kelembaban adalah 42,26% dan 60,66% dengan persamaan regresi y=55,412+7,3164x dan y=60,195 +0,0166x. Perbedaan kontribusi dan persamaan regresi naturalness index dan indeks kualitas biodiversitas disebabkan karena karakteristik masing-masing indeks. Pada indeks kualitas biodiversitas hanya 4 dari total 29 karakter yang tersedia.

Etika Keilmuan dan Tanggung Jawab Sosial Ilmuwan (Sebuah Kajian Aksiologis)
Ningrat, Hadi Kusuma
Secara aksiologis pengembangan ilmu pengetahuan dan penggunaan teknologi harus selalu mengacu pada wawasan yang kudus dan kemanusiaan. Dengan kata lain, penekanan pada aspek vertical dan horizontal sebagai landasan moral dalam berkarya dan berinovasi merupakan keniscayaan yang harus dilakukan. Dengan berlandaskan iman dan berorientasi pada kemaslahatan manusia sebagai visi dan misi perjuangan tentu peradaban dunia akan menapaki era emas, dimana nilai-nilai kemanusiaan terjaga dan sarat nilai ketuhanan. Untuk itu, dalam konteks ini agama, etika, estetika, dan aturan adat harus tetap terjaga. Jangan sampai pengembangan ilmu pengetahuan menganut konsep barat yang sekuler dan antroposentris yang bias membuat dunia semakin berantakan dan gersang nilai ketuhanan.

Supardan, Dadan
Widada, Jaka
Wibawa, Tri
Wijayanti, Nastiti
Infeksi virus dengue (DENV) merupakan infeksi yang menjadi salah satu masalah kesehatan utama di dunia dan salah satu infeksi yang sangat berbahaya terutama dinegara tropis seperti Indonesia.Infeksi dengue disebabkan oleh 4 serotipe virus dengue (DENV-1, DENV-2, DENV-3, dan DENV-4). Virus dengue serotipe 3 (DENV-3) merupakan serotipe dengan karakteristik lebih virulen. Sampai saat ini belum tersedia vaksin dan obat untuk pencegahan dan pengobatan infeksi virus dengue, sehingga penelitian penemuan obat demam berdarah sangat penting dilakukan, akan tetapi pengujian virus dengue pada kultur sel atau cell-line masih banyak mengalami kendala. Salah satu kendala yang sering dijumpai peneliti dalam pengujian senyawa tertentu terhadap virus dengue yaitu virus tersebut tidak mampu berkembang secara optimal pada beberapa jenis kulturcell-line, sehingga dilakukan pengujian untuk mengetahui viabilitas virus dengue pada beberapa kultur cell-line. Penelitian ini bertujuan untuk mengetahui kulturcell line yang paling cocok digunakan untuk berbagai pengujian infeksi DENV-3.

Optimalisasi Tingkat Pertumbuhan (Growth Rate) dan Mortalitas (Survival Rate) Ikan Nila (Oreochromis Niloticus) dengan Enzim Papain Kasar
Ihsan, Muhsinul
Mahsul, Alwan
Ikan Nila adalah salah satu ikon penyelamat perkembangan budi daya ikan air tawar karena teknologi pemeliharaannya sudah berkembang dengan baik. Salah satu permasalahan dalam pembudidayaan Ikan Nila adalah mahalnya biaya pakan. Solusi untuk mengatasi hal ini adalah pengayaan pakan yang memiliki kualitas rendah dengan enzim papain kasar. Tujuan penelitian ini adalah untuk mengetahui pengaruh enzim papain kasar terhadap pertumbuhan dan survival rate Ikan Nila. Penelitian ini telah dilakukan selama 30 hari di kolam budidaya milik masyarakat Gubuk Barat I Desa Mamben Daya Kec. Wanasaba Lombok Timur. Terdapat 4 tahapan dalam prosedur kerja yang digunakan yaitu: preparasi enzim papain kasar, pencampuran enzim papain kasar dengan pelet, pengujian pelet yang telah dicampur dengan enzim papain kasar, dan evaluasi pengaruh enzim papain kasar. Hasil penelitian menunjukkan bahwa enzim papain kasar mampu meningkatkan pertumbuhan Ikan Nila sebesar 4 Kg selama 30 hari, hampir empat kali lipat lebih tinggi dibandingkan pertumbuhan Ikan Nila yang tidak diberikan enzim papain kasar. Survival rate Ikan Nila yang ditambahkan enzim papain kasar sebesar 78,09%, lebih besar dibandingkan survival rate Ikan Nila yang tidak ditambahkan enzim papain kasar. Enzim papain kasar mampu meningkatkan pertumbuhan Ikan Nila secara signifikan. Akan tetapi, belum mampu menekan tingkat mortalitas Ikan Nila secara signifikan.

Eksistensi Manusia dalam Manajemen Pendidikan Islam (Tinjauan Kritis dari Segi Fungsi Penggerakan/Motivating)
Ningrat, Hadi Kusuma
Manajemen organisasi akan terlaksana dengan baik jika tersedia sumberdaya organisasi yang dibutuhkan, yang dikenal dengan singkatan 7 M (man, money, machines, material, marketing, methods, dan minutes). Berdasarkan sudut pandang fungsi penggerakan (motivating) dalam manajemen (khususnya manajemen pendidikan Islam) bahwa asset yang maha penting di antara sumber daya organisasi tersebut adalah sumber daya manusia (man). Keberadaannya sebagai penggerak utama sumber daya organisasi lainnya. Hal tersebut akan terwujud, apabila tujuan/kepentingan organisasi dan kepentingan anggota organisasi sinergis; saling menguntungkan. Untuk tujuan tersebut, maka pimpinan organisasi perlu mengetahui dan memahami karakteristik anggota organisasinya. Lebih lanjut pembahasan tentang eksistensi manusia dari segi fungsi penggerakan (motivating) dalam manajemen pendidikan Islam akan diuraikan di bawah ini.

Analisis Kualitas Air Tanah di Desa Lepak Kecamatan Sakra Barat Lombok Timur
Nizar, Muhammad
Rahman, Nanang
Haifaturrahmah, Haifaturrahmah
Kesehatan lingkungan mencakup aspek lingkungan tanah, perairan, dan udara. Mengingat kondisi dekonstruksi lingkungan hidup saat ini pernting untuk terus dilakukan penelitian secara berkesinambungan terhadap kualitas lingkungan. Dalam penelitian ini, dilakukan analisis terhadap kualitas air pada lokasi sumur warga yang dekat dengan permukiman. Penelitian dilakukan di Desa Lepak Kabupaten Lombok Timur. Pengukuran parameter kualitas air dilakukan untuk mengukur parameter air tanah. Pengukuran parameter air tanah (suhu, warna, rasa/bau, keasaman/pH dan kandungan E. coli) di laboratorium dengan sampel yang diambil pada sumur yang telah ditentukan sebagai titik pengambilan sampel. Sementara untuk parameter rasa dan bau dilakukan pengamatan langsung di lapangan. Hasil penelitian menunjukkan bahwa kualitas air tanah secara parameter fisik (suhu, warna, kekeruhan,rasa dan bau) sudah memenuhi kriteria kualitas air bersih, berdasarkan parameter kimia mendekati pH air netral. Sedangkan parameter biologi (Escherchia Coli) tidak memenuhi kriteria kualitas air bersih yang dapat digunakan sebagai bahan baku air minum. Meskipun demikian sebelum diminum air bersih tersebut harus dilakukakan perlakuan (dimasak). Tingginya parameter biologi sudah melampaui ambang batas, menyebabkan air pada sumur-sumur tersebut tidak layak digunakan untuk air minum sebelum dimasak terlebih dahulu.

Peran Guru dalam Pengembangan Moral Bagi Anak Usia Dini
Sukmawati, Ati
Pendidikan sebagai sarana pelestarian moralitas sekaligus pengembangan tatanan kehidupan manusia memiliki peran dan fungsi yang sangat penting serta efektif. Usia taman kanak-kanak dan kelompok bermain adalah saat yang paling baik bagi guru untuk meletakkan dasar-dasar pendidikan nilai, moral, dan agama. Pengembangan moral dan nilai-nilai keagamaan memerlukan pembiasaan di samping pemahaman dan penghayatan. Ada beberapa peran yang dapat dan harus dilaksanakan oleh guru yaitu; sebagai model, pembimbing, pelatih, motivator, dan sebagai penilai. Di samping peran-peran tersebut yang tidak kalah penting diperhatikan adalah materi pembelajaran moral dan nilai-nilai keagamaan pada PAUD harus bersifat; aplikatif, menyenangkan, dan mudah ditiru. Kemudian faktor lain yang harus dipertimbangkan adalah metode yang diterapkan dalam pengembangan moral, ada beberapa metode yang bisa digunakan sesuai dengan tingkat kemampuan anak, yaitu metode Bercerita, Bernyanyi, Karyawisata, dan Syair atau Sajak.

Peningkatan Mutu Madrasah Berkelanjutan (Sustainability) Berbasis Kinerja Guru
Suhirman, Suhirman
Masih rendahnya tingkat profesionalisme guru saat ini disebabkan oleh faktor-faktor yang berasal dari internal guru itu sendiri dan faktor lainnya yang berasal dari luar. Pada konteks madrasah, beberapa sifat yang harus dimiliki guru antara lain: pendidik harus memiliki keteladanan (uswah hasanah) dalam sifat tujuan, tingkah laku da pola berpikir guru bersifat rabbani yakni hendaknya selalu bersandar kepada Rabb dengan mentaatiNya, mengabdi kepadaNya, mengikuti syariatNya dan mengenal sifat-sifatNya; hendaknya guru seorang yang ikhlas; guru bersabar dalam mnegajarkan berbagai pengetahuan kepada anak-anak; jujur dalam menyampaikan informasi; senatiasa membekali diri dengan ilmu dan kesediaan membiasakan diri untuk terus mengkajinya, guru berpengetahuan luas dengan ilmu yang dikajinya; hendaknya guru mampu menggunakan berbagai metode mengajar secara bervariasi. Penguasaan ilmu saja belum cukup, karena tidak setiap orang berilmu mampu mentrasformasikan ilmunya kepada peserta didik secara efektif; guru mampu mengelola siswa, tegas dalam bertindak serta meletakkan berbagai perkara secara proporsional; mempelajari kehidupan psikis para pelajar selaras dengan masa perkembangannya ketika mengajarkannya; tanggap terhadap berbagai kondisi dan perkembangan dunia yang mempengaruhi jiwa, keyakinan; dituntut bersikap adil terhadap seluruh siswa.

Student center learning leads to changing teacher roles. This resulted in a shift in the role of teachers. Learners are required to have HOTS (High Order Thinking Skill), one of the capabilities including HOTS is critical thinking ability. The purpose of this research is to know the influence of learning model of Reciprocal Teaching (RT) and Problem Based Learning (PBL) to critical thinking ability of high school students on reproduction system material. The method used in this research is quasi experiment with Post-Test Only Control Group Design. After obtained the results of the calculation of ANOVA test one way and critical data, then obtained significance value less than 0.05 is 0.001 <0.05 then rejected H0, meaning there is a difference in the average ability of critical thinking learners. The difference of students' critical thinking ability between the RT experimental class and the Student Team Achievement Divisions (STAD) control class proves that there is an influence of the RT learning model on critical thinking skills. The involvement of learners in PBL learning can help in developing critical thinking skills, because PBL involves the ability of learners to search and investigate logically, critically and analytically so that they can formulate their own problem solving. Based on the results of research and hypothesis testing it can be concluded that there is the influence of learning Reciprocal Teaching (RT) and Problem Based Learning (PBL) on the critical thinking skills of high school students on the material reproduction system.

Jernang is one of the wild trees that are from the family of rattan with the genus of Daemonorops. The objective of this research is to know the availability, user, harvest, and conservation of the Jernang as well as the barrier faced by the jernang hunters, jernang harvest, and jernang conservation. This study is the done using descriptive research methodology. Respondents were chosen by purposive sampling. They were chosen with special considerations such as they must be the jernang hunters or the people who well understand the jernang. The data were collected through interview and participant observation and then analyzed descriptively. The research findings showed that the respondents still hunted the jernang in the forest and they sold to the buyers in their villages. Jernang fruits were processed by extracting them to get their substances. The conservation efforts have many threats due to the expansion of the palm plantation. The lack of people knowledge of good jernang for the seed is also one of the barriers of conservation.

Curcumin Effectivity on Hepar and Reproductive Organ Recovery Male Mice (Mus musculus L) after Methoxychlor Exposure
Curcumin Effectivity on Hepar and Reproductive Organ Recovery Male Mice (Mus musculus L) after Methoxychlor Exposure
Mahriani, Mahriani
Fajariyah, Susantin
Utami, Eva Tyas
Methoxychlor (MXC) is an insecticide (DDT derivates) that has the potential for bioaccumulation in mammal and causes a disruptive effect on the hepar and reproductive system. This study was done to find out the benefits of curcumin as a natural ingredient to overcome the negative impact of Methoxychlor (MXC) on hepar and male reproductive organ of Balb’C mice (Mus musculus L). The study was carried out in a Completely Randomized Design (CRD) Posttest Only Control Group Design used four treatments and six replications. The curcumin treatment after administration of MXC was carried out by gavage with curcumin doses: 0.05; 0,1; and 0.2 mg/g body weight, every day for two weeks, respectively. Histological observations of the liver, and testis was performed using the paraffin method and Hematoxylin Eosin stained. The results showed that MXC exposure caused liver disruption by increasing the number of pycnotic necrotic hepatocytes and hydrophic degeneration hepatocytes. On the male reproductive organ, MXC caused testis impairment by reducing the number of Sertoli cells and Leydig cells, spermatogenic cell counts, and the diameter of seminiferous tubules. The administration of curcumin at doses of 0.1 mg/g bw in mice exposed to methoxychlor can reduce the number of hydrophic degeneration hepatocytes and tend to reduce the number of pycnotic hepatocytes; and also increase the number of Sertoli cells, the number of spermatogenic cells, and the diameter of the seminiferous tubules, and tend to reduce the amount of Leydig cells. Curcumin treatment tends to recover hepar dan testis disruption of mice that were exposed by MXC.

Sari, Dewi Ratih Tirto
Coffee is one of the essential crops commonly cultivated in Indonesia. Coffee contains diverse bioactive compounds, which are associated with human health benefits. One of the compounds is Chlorogenic acid, which able to decrease the risk of type 2 diabetes mellitus (T2DM). However, the mechanism of chlorogenic acid toward anti-diabetes still unclear. This study aimed to analyze and investigate the potential role of chlorogenic acid as anti-diabetes through their interaction with Peroxisome proliferator-activated receptor gamma (PPAR-γ) as an enzyme to phosphorylate and regulate the mechanism of T2DM. The physicochemical properties of chlorogenic acid also performed in this study. The PPAR-γ was downloaded from the PDB database, and the chlorogenic acid was retrieved from the PubChem database. The protein and ligand were prepared using the PyRx program and were docked using Hex 8.0.0 software. Discovery Studio client 4.1 software was used to analyze the interaction between chlorogenic acid and PPAR-γ protein. Based on the physicochemical properties, chlorogenic acid is highly permeable to the cell and easily absorbed. Thirteen amino acid residues of PPAR-γ (GLN410, SER394, ASP396, GLY395, GLU407, LEUA401, LEU400, VAL403, LYS373, LYS438, LEU377, LYS434, and GLY437) were identified on the chlorogenic acid-PPAR-γ interaction. Interestingly, the kind of interactions, including hydrophobic interaction, hydrogen bond, and van der Waals, which are supported by the tight interaction. Our study indicated that chlorogenic acid might have anti-diabetes activity through PPAR-γ interaction.

Four of which are the endemic species of Lesser Sunda Islands, namely Oreophryne monticola, Limnonectes kadarsani, Limnonectes dammermani dan Hylarana florensis. However, the information regarding the habitat characteristic which supports animal survival is limited. This study aimed to explore the types of habitat characteristics according to amphibian diversity in the Island of Lombok. The survey study was conducted at 9 locations (3 of habitat type) from March to July 2016. The collected data includes species composition and a sum of individuals of species. Amphibian diversity was analyzed using relative abundance and the Shannon-Wiener index. This study revealed that the nonforest habitat type was appropriate for five species, while secondary and primary forest habitat type was appropriate for seven species. Diversity of species index directly proportional to a natural level of habitat (H’ Nonforest = 1.3; H’ Secondary Forest = 1.7; H’ Primary Forest = 1.8). The highest species abundance was Bufo melanostictus (23.9%), and the lowest species abundance was Oreophryne monticola (0.9%). According to the distribution and relative abundance, the species that require conservation priorities are Oreophryne monticola and Hylarana florensis.

Sari, Indah Juwita
The cell wall component of root endophytic fungi is a main source of chitosan synthesis. This research aimed to optimize chitosan synthesis from three different isolated species of root endophytic fungi in Pulau Dua Nature Reserve, Banten Indonesia. Three species of root endophytic fungi, namely, Aspergillus niger, Aureobasidium sp., Basipetospora sp., were cultured to produce chitosan. To optimize the production of fungal chitosan, cultures were treated with different conditions such as growth medium (Oat Meal broth, Potato Dextrose Broth, CMMY Broth), pH value (4, 5, 6, 7), and temperature (25, 30, 35, 40°C). Chitosan was extracted from dried mycelium after treated on NaOH 10% at 121°C for 2 min. The degree of deacetylation (DD) of chitosan was then examined and compared with the control (shrimp chitosan). The optimum fungal chitosan condition was higher in CMMY medium, pH 5, and 30°C. The DD value of three root endophytic fungi species, Aspergillus niger, Aureobasidium sp., Basipetospora sp. were 88.5, 83.3, 80.8, respectively, which was lower than DD value resulted from control. This study indicates that Aspergillus niger was a potential endophytic fungi for chitosan synthesis.

Rheotaxis Response Based on Sexual Dimorphism in the Green Swordtail Fish, Xiphophorus hellerii
Irsyad Abiyusfi Ghafari, Muhammad
Fitrianti, Vita
Morphological distinctions between males and females of a species are referred to by sexual dimorphism. It may result from various selection pressures affecting either sex or both and may occur in any dioecious species, including Green Swordtail fish, which are sexually reproductive. This study examined the different rheotaxis responses of Xiphophorus hellerii based on different sexes and morphological features. We analyzed ten adult males, ten gravid females, and ten non-gravid females of Xiphophorus helleri collected down the river and transferred into the column. We counted the number of the individual that performed positive rheotaxis (+), negative rheotaxis (-), and indifference response (0). The result showed different rheotaxis responses shown by male, non-gravid female, and gravid female X. hellerii. The highest percentage of positive rheotaxis response (movement against the current) was shown by non-gravid female X. hellerii, reaching up to 89%. Morphological differences between male, non-gravid female, and gravid female X. hellerii appear to affect the orientation and ability of X. hellerii in giving response against current and certainly has an impact on their survival in nature.

Preliminary Detection of Antibacterial Activity of Fishpond Water Bacteria against Aquaculture Pathogenic Bacteria
Deteksi Awal Aktivitas Antibakteri dari bakteri air tambak terhadap bakteri patogen akuakultur
Magdalena, Stella
Sindy, Sindy
Yogiara, Yogiara
Aquaculture is currently experiencing massive loss due to the outbreak of pathogenic bacteria. One of the outbreak causes is the development of pathogenic bacterial resistance to the antibacterial. The problem can be solved using microorganisms that can produce new antibacterial compounds. The purpose of this research was to obtain bacteria from fishpond water that could produce antibacterial compounds. About two out of 81 isolates could produce antibacterial compounds. Those two isolates were obtained from saltwater fishponds in North Jakarta (TS2) and Harapan Island (PHY). All fishpond water was grown in marine broth or Luria broth. Extraction of antibacterial compounds was performed using four types of solvents: chloroform, dichloromethane, ethyl acetate, and methanol. Each of the solvents showed a different result. The extraction can only be successfully performed using chloroform and dichloromethane. Extraction using dichloromethane showed a larger inhibitory clear zone than chloroform. Based on 16S rRNA gene sequencing, PHY isolate was identified as Bacillus sp. and TS2 as Acinetobacter sp. In conclusion, isolate TS2 and PHY, which produced antibacterial compounds, showed potential use as aquaculture probiotics.

Kurniawan, Febri Yuda
Santoso, Agung Dwi
Stomata activity in orchids is related to orchids' adaptation process to their environment. This study aimed to investigate the stomata profile, comprising of anatomical structure and density of the two orchids species, Dendrobium aphyllum, and Arachnis flos-aeris. Data was collected by printing the leaves' surface using glue and observed at 09.00 am and 09.00 pm, then analyzed using Image raster 3.0 software and MS. Excel. The stomata of D. aphyllum and A. flos-aeris were characterized by anomocytic type. Results showed that the highest stomata density was 1177.78 um2, found on the abaxial part of D. aphyllum. The adaxial leaves of both species were classified as low or no stomata. These two orchid species were epiphyte yet grow in different habitats. Arachnis flos-aeris exposed to direct sunlight tends to reduce transpiration rate, resulting in fewer stomata than D. aphyllum less exposed to sunlight.

Fajriah, Siti Nur
Inggraini, Maulin
Ilsan, Noor Andryan
Anindita, Reza
Enterobacter cloacae is a Gram-negative bacteria causing nosocomial infections. This bacteria has increased resistance to various antibiotics in the past five years, resulting in a multi-drug-resistant (MDR) phenotype. In particular, MDR E. cloacae causes longer hospitalization time, increases medical costs, and affects morbidity and mortality. This study aimed to observe the minimum inhibitory concentration (MIC) of clinical E. cloacae towards several antibiotics and molecular identification of MDR E.cloacae. This study was conducted in a descriptive design. Secondary data was collected at the microbiology laboratory of the Teaching Hospital in Bekasi, Indonesia, from May to September 2020. Sampel was carbapenem resistant E.cloacae. The isolate was originated from a human clinical specimen, then was confirmed molecular identification using 16s rRNA. In this study, only one carbapenem-resistant E. cloacae, which is also MDR bacteria, was found. This E. cloacae was categorized as MDR bacteria since it was resistant to more than three antibiotic classes, including carbanemen, extended-spectrum cephalosporin, penicillins + β lactamase inhibitor, antipseudomonal penicillins + β lactamase inhibitor aminoglycoside, and penicillin. Vitek 2 identification of this isolate was E. cloacae complex. It showed similar results to molecular identification based on a partial sequence of 16s rRNA. BLASTn result of the trimmed sequence was E. cloacae with 99.78 % similarity.

Plant host symbiosis is close related to soil microbial abundance. Soil microbial abundance will affect soil quality and fertility, thus will improve plant growth. Studies on soil microbial abundance in succulent plant rhizosphere, especially in Indonesia, are scarce. This study aims to observe soil microorganisms' existence and their abundance on succulent plant rhizosphere. This research used two primary methods to isolate Arbuscule Mycorrhizal Fungi (AMF) and actinomycetes. The spore extraction (soil separating) method was used to obtain AMF spores, followed by the root staining method to observe AMF infection on the plant roots. Serial dilution and pour plate method were used for isolation of Actinomycetes. The isolation results showed a high number of Actinomycetes distribution up to 3.3 x 106 Actinomycetes CFU/g from the plant Echinocactus grusonii, while AMF spores displayed the most elevated number up to 47 spore/25g from the plant Deuterocohnia sp. The percentage of AMF root infection is covered by 27,9% median. AMF identification was based on spore. The result showed an abundance presentation of Actinomycetes in each soil sample. AMF and Actinomycetes existence displayed symbiotic interaction between succulent plants and soil microorganisms. AMF and actinomycetes play the role of endophytes that help the growth of cacti, generally have a dry growing environment, and limited nutrition by this symbiotic interaction. Actinomycetes distribution in rhizospheric soil will increase plant growth-promoting factors activity. Eventually, the implications of research results are to explore the abundance and biodiversity of soil microorganisms from succulent plant rhizosphere that lacked exploration.

Comparison of the Chaetodontidae Mitochondrial Genome
Ferdyan, Rhavy
Razak, Abdul
Ahda, Yuni
The mitochondrial genome is useful for identification because the mutation rate of mtDNA is higher than nDNA. Previous studies have carried out many analyses on the mitochondrial genome of several species, the Chaetodontidae group. Fish in this group are biological indicator fish of coral reefs, so their molecular characteristics must be enriched to conserve these fish. This article aims to review several forms of the mitochondrial genome of the Chaetodontidae group of species, including: Chaetodon speculum, Chaetodon octofasciatus, Chaetodon wiebeli, and Heniochus chrysostomus. Data were collected qualitatively by reviewing previous research articles related to the Chaetodontidae mitochondrial genome. The review focused on the characteristics of each species' mitochondrial genome, including length, overall composition, tRNA, and non-coding region. Each species exhibits various features of the mitochondrial genome and is mapped in its phylogenetic analysis.

Indonesia has a tropical monsoon-type climate which suitable for agriculture and plantations. One of the main centers of orange fruits (Citrus sp.) production in Indonesia and become the top ten with the largest production is in South Sulawesi. Farmers commonly cultivate siam oranges (Citrus nobilis). Lime (Citrus aurantifolia) has not yet become the main production, which is inversely proportional to the high demand in South Sulawesi. This study aims to determine the ability of bio-catharanthine as a polyploidy agent against the phenotype of the familia Rutaceae cultivated in South Sulawesi. The research was carried out in Laboratory of Genetics and Molecular Biology, Department of Biology, Universitas Islam Negeri Alauddin Makassar using randomized complete block design consisted of two conditions (bio-catharanthine concentration including C1 = Bio-catharanthine 0.05%; C2 = Bio-catharanthine 0.075%; C3 = Bio-catharanthine 0.1% and immersion time including T1 = 3 h; T2 = 6 h). Phenotypic observations include plant height, the number of leaves and nodes, the length of roots, and the number of roots per shoot. The results of the study showed that the bio-catharanthine immersion of 0.05-0.075% for 6 hours in Rutaceae had a significant effect on their phenotypic characters.

One of the marine commodities, Lobster (Panulirus spp.), has unabated demand in the global market, while, Lobster production remains static due to the difficulty of implementing its rearing activities. Relative rearing of lobster (Panulirus spp.) is usually performed using the floating net cage method with calm water conditions. In contrast, areas with extreme weather conditions tend to have difficulty applying this method. The potential of using the fixed cage method was assessed by rearing the Lobster at Pesona Bahari Banyuwangi Fish Cultivation Group. This research aimed to investigate the feasibility of the environmental conditions in the waters of GWD, Banyuwangi. The study was conducted for three months. Data such as temperature and light intensity through the help of a pendant was collected. Water quality parameters were recorded during this study, including salinity, pH, dissolved oxygen, and current velocity. Sampling was conducted four times to see the relationship between length and weight. The results showed that the GWD environmental parameters were very supportive for lobster rearing, with temperature values ranging from 27.2oC - 30.1oC, DO around 4.6 mg/l - 5.2 mg/l, salinity 28o/oo - 30o/oo, pH 7 - 8.2, the current speed is 0.468 m/s, and the light intensity is 0 lux - 3,616 lux. The growth pattern of all sampling results except sampling 2 (isometric) has a negative allometric result, with length and weight having a solid relationship. The fixed cage method is considered suitable for lobster rearing activities because the environmental parameters follow their natural habitat and the Fulton condition factor (K) value of more than 1. The greater the value of the Fulton condition factor (K), the healthier the condition lobster.
