Analisis Variasi dan Filogenetik Keragaman Gen 16S rRNA pada Staphylococcus aureus Berdasarkan Data NCBI
type: item
description: Staphylococcus aureus merupakan bakteri patogen penting yang sering dianalisis menggunakan gen 16S rRNA karena gen ini memiliki wilayah konservatif yang stabil sekaligus daerah hipervariabel yang informatif untuk kajian filogenetik. Penelitian ini bertujuan untuk menganalisis validitas data, tingkat keragaman genetik, hubungan filogenetik, serta indikasi penyebaran geografis S. aureus berdasarkan sekuens gen 16S rRNA. Sebanyak 60 sekuens gen 16S rRNA yang berasal dari berbagai benua dianalisis menggunakan pendekatan bioinformatika. Hasil analisis menunjukkan bahwa seluruh sekuens memiliki panjang yang bervariasi namun masih berada dalam rentang yang layak untuk analisis filogenetik. Multiple sequence alignment memperlihatkan dominasi nukleotida konservatif dengan jumlah SNP dan situs variabel yang relatif sedikit, menandakan tingkat keragaman genetik yang rendah pada gen 16S rRNA S. aureus. Analisis filogenetik menggunakan metode Neighbor-Joining dengan 500 kali bootstrap menghasilkan empat klaster utama (A–D) dengan tingkat dukungan yang bervariasi, menunjukkan adanya hubungan evolusi yang berbeda antar isolat. Secara keseluruhan, hasil penelitian ini mengindikasikan bahwa gen 16S rRNA S. aureus bersifat relatif stabil dan mendukung penggunaannya sebagai penanda molekuler untuk studi filogenetik dan epidemiologi global.

Analisis Filogenetik Gen nosZ pada Bakteri Pseudomonas sebagai Denitrifikasi Nitrogen Berbahaya Berdasarkan Data Sekuens NCBI
type: item
description: The nosZ gene plays a crucial role in the reduction of nitrous oxide (N₂O) to dinitrogen (N₂), an environmentally benign form of nitrogen. However, the evolutionary diversity of this gene within the genus Pseudomonas has not been comprehensively investigated. This study aimed to analyze the phylogenetic relationships of the nosZ gene in Pseudomonas and to elucidate patterns of relatedness and clade differentiation associated with N₂O reduction capability within this bacterial group. Phylogenetic analysis was conducted using the Maximum Likelihood method based on nosZ nucleotide sequences obtained from the NCBI database. The results showed that the closest genetic relationships were observed among isolates belonging to the same species, including Pseudomonas lini (sp 18 and 19), P. brassicacearum (sp 6 and 7), P. grimontii (sp 16 and 17), and P. mandelii (sp 11 and 12), all of which exhibited a genetic distance of 0.00. This finding indicates a high level of sequence conservation, likely influenced by strong functional selective pressure and similar geographic origins. In contrast, the most distant genetic relationships were observed between P. mandelii (sp 11) and P. lini (sp 19) with a genetic distance of 0.5, as well as between P. brassicacearum and several other species with distances reaching up to 0.6. These results highlight significant evolutionary variation of the nosZ gene among Pseudomonas species.

Analisis Bioinformatika GenblaCTX-M Pengkode β-Laktamase Spektrum Luas pada Klebsiella pneumoniae Menggunakan Data GenBank NCBI
type: item
description: Klebsiella pneumoniae is a short rod-shaped Gram-negative bacterium capable of fermenting lactose and various other carbohydrates, producing acid and gas. The blaCTX-M gene is one of the major genes responsible for β-lactam resistance in K. pneumoniae. This study aimed to analyze the genetic variation and phylogenetic relationships of the blaCTX-M gene in K. pneumoniae using nucleotide sequence data retrieved from the NCBI GenBank database. A total of 19 sequences representing isolates from different countries were aligned to identify nucleotide variations. The alignment results revealed genetic variation among the isolates, with most forming a closely related cluster indicating high sequence similarity. Eighteen isolates showed identical characteristics with minor variations, while one isolate, NG_048898, exhibited the highest number of nucleotide variations. A total of 168 nucleotide variations were identified, predominantly nonsynonymous substitutions, distributed throughout the nucleotide sequence. Phylogenetic analysis using the Neighbor-Joining method with the Kimura 2-parameter model supported the alignment results, showing a distinct branch for isolate NG_048898, suggesting a different evolutionary origin. These findings highlight the genetic diversity of the blaCTX-M gene in K. pneumoniae isolates and provide important insights into the distribution of β-lactamase genes, which are essential for understanding antibiotic resistance patterns.

Identifikasi Molekuler Bakteri Simbion Spons Spongia sp. Penghasil Antibakteri
type: item
description: This study aims to identify antibacterial-producing symbiotic bacteria in sponges using a molecular approach based on 16S ribosomal RNA (16S rRNA) genes as an initial step towards the sustainable use of marine biological resources. A total of six symbiotic bacterial isolates were successfully isolated from Spongia sp. sponges and exhibited differences in colony morphology characteristics. All isolates were tested for antibacterial activity against Escherichia coli and Bacillus subtilis. The test results showed that all isolates had the ability to inhibit the growth of test bacteria with inhibition zone diameters ranging from 5.0–8.5 mm against E. coli and 6.0–9.0 mm against B. subtilis. Among all isolates, Sp2 exhibited the highest antibacterial activity and was broad-spectrum, with stronger inhibitory power against Gram-positive bacteria. Isolate Sp2 was further molecularly identified using the 16S rRNA gene. Amplification results showed a DNA fragment of approximately 520 base pairs. Phylogenetic analysis based on the 16S rRNA gene sequence placed isolate Sp2 within the Bacillus genus, with the closest affiliation to Bacillus subtilis and supported by high bootstrap values, indicating a strong genetic relationship. Overall, the results of this study indicate that isolate Sp2 is the most promising symbiotic bacterium of the sponge Spongia sp. as a producer of antibacterial compounds against E. coli and B. subtilis. This isolate has the potential to be further developed as a source of antibacterial bioactive compounds, thus requiring further research to identify and characterize the active compounds it produces.

Isolasi Bakteri Selulolitik Pada Ayam Kampung (Gallus gallus domesticus) Sebagai Kandidat Probiotik Ternak Unggas
type: item
description: This study aims to isolate cellulolytic bacteria derived from local chickens (Gallus gallus domesticus) and evaluate their potential in degrading cellulose in test media (CMC). Isolation was performed from the gastrointestinal tract of local chickens, which is expected to contain microorganisms with cellulose-degrading capabilities. The results of this study showed that the isolated bacteria can effectively break down cellulose, indicating their potential as probiotics that can help improve digestive health in poultry. Cellulolytic activity was tested by measuring the clear zone formed on agar media containing cellulose. The U5 bacterial isolate exhibited the highest ability to degrade cellulose substrate on agar media, marked by a clear zone of 35 mm, followed by U3 with a zone size of 33 mm. The formation of a clear zone on the CMC test medium indicates the presence of probiotic bacterial candidates, which need to be further tested for their biochemical characteristics to determine the biochemical properties of each bacterial candidate.

Pengaruh Beberapa Jenis Fermentor terhadap Kandungan Protein Kasar, Serat Kasar, dan Lemak Kasar Jerami Jagung
type: item
description: This study aimed to evaluate the effect of different fermentors on the crude protein (CP), crude fat (CF), and crude fiber (CFb) content of fermented corn straw as an alternative feed for ruminants. The experiment was conducted at the Laboratory of Animal Nutrition and Feed Science, Faculty of Animal Husbandry, University of Mataram, using a Completely Randomized Design (CRD) with four treatments and three replications: P0 (untreated/control), P1 (fermented with 1.5% EM4), P2 (fermented with 1.5% MA-11), and P3 (fermented with 1.5% Starbio). Fermentation lasted 21 days, followed by proximate analysis. The results showed that the type of fermentor significantly affected (P < 0.05) the nutrient composition of corn straw, with an increase in CP and CF, and a decrease in CFb. EM4 yielded the highest CP content (4.73%), while Starbio produced the highest CF content (1.42%) and the lowest CFb content (31.79%). In conclusion, fermentation using Starbio was the most effective in improving the nutritional quality of corn straw, particularly through enhanced CP and CF levels and reduced CFb content

Populasi dan Intensitas Serangan Hama Kutu Daun (Aphis Gossypii) dan Gejala Penyakit Virus yang Ditimbulkan pada Beberapa Varietas Tanaman Kentang
type: item
description: Potatoes are a short-lived horticultural crop with a growing period of 90–180 days, depending on the variety, and are a significant source of carbohydrates widely used as vegetables and food ingredients in several countries. Potatoes are best cultivated in highland areas or mountainous regions at altitudes above 700 meters above sea level. Various potato varieties have been developed for export, food industries, and local consumption as vegetables. In Indonesia, common varieties include Atlantik and Chitra, while Mc Russet and Ranger Russet are new industrial varieties under evaluation due to the lack of descriptive data. Superior traits in a potato variety are often associated with reduced incidence and severity of pests and diseases. A study aimed to examine the population and intensity of aphid (Aphis gossypii) infestations and virus symptoms across potato varieties was conducted from April to June 2021 in Sembalun Village, East Lombok Regency, West Nusa Tenggara Province, using a randomized block design (RBD) with four treatments Mc Russet, Ranger Russet, Chitra, and Atlantik each repeated six times, resulting in 24 experimental units. The findings indicated significant differences in pest populations, infestation intensity, and virus symptoms among varieties, with Atlantik having the highest pest population (10 pests/plant) and infestation intensity (2.93%), while Ranger Russet had the lowest (3.42 pests/plant and 1.57%). Virus symptoms were most severe in Chitra (PVY 6.05%, PLRV 5.79%) and least severe in Ranger Russet (PVY 3.19%, PLRV 2.27%).

Respon Pertumbuhan Udang Vaname (Litopenaeus vannamei) terhadap Pakan Ekstrak Daun Jarak Pagar (Jatropha curcas) dengan Dosis Berbeda
type: item
description: Pacific white shrimp (Litopenaeus vannamei) is a leading aquaculture commodity in Indonesia, valued for its high nutritional content, rapid growth, and disease resistance. However, pathogenic infections such as Vibrio spp. can cause mortality rates of up to 100% within a day, necessitating strategies to enhance immune function. This study aimed to evaluate the effect of incorporating Jatropha curcas leaf extract into feed on the growth performance and survival of L. vannamei. The experiment was conducted for 60 days using a Completely Randomized Design with four treatments: control (no extract), 1%, 2%, and 3% J. curcas leaf extract, each with three replicates. Parameters measured included absolute weight gain, absolute length gain, specific growth rate (SGR), feed conversion ratio (FCR), and survival rate (SR). Results showed that the 3% treatment (JC3) achieved the highest absolute weight gain (6.37 g), significantly higher (p<0.05) than the control and JC1, but not significantly different from JC2. The highest SGR was also recorded in JC3, while the lowest FCR (1.2) was observed in JC3, which was not significantly different from the control. The improved growth performance with J. curcas supplementation is likely attributed to its bioactive compounds, such as tannins and flavonoids, which possess antibacterial and immunostimulant properties, thereby enhancing shrimp health and feed utilization efficiency. This study recommends a 3% inclusion level of J. curcas leaf extract in feed as an optimal dose to support the growth of L. vannamei.

Mangrove Conservation Model Based on Pentahelix Approach: Lesson Learned from Various Countries
type: item
description: Mangrove ecosystems play a crucial role in coastal protection, biodiversity conservation, and climate change mitigation. However, their degradation due to deforestation, land conversion, and pollution remains a significant challenge. This study proposes a mangrove conservation model based on the Penta helix approach, which integrates the collaboration of five key stakeholders: government, private sector, academia, community, and media. The model emphasizes a multi-stakeholder synergy to enhance policy implementation, sustainable economic incentives, scientific research, local engagement, and public awareness. Through qualitative analysis and case studies, this research identifies challenges such as regulatory gaps, conflicting interests, and limited community participation. The findings suggest that a well-coordinated Pentahelix framework can strengthen conservation efforts, promote sustainable livelihoods, and improve mangrove ecosystem resilience. The study concludes that effective governance, corporate responsibility, scientific contributions, community empowerment, and media advocacy are essential for the long-term sustainability of mangrove conservation.

Analysis of Land Cover Change in Aik Berik Village Area, Central Lombok Regency
type: item
description: Land cover change in tourist areas is often an important issue related to the impact of human activities on the environment. This study aims to analyze land cover changes in the Aik Berik Village area, Central Lombok Regency, by utilizing remote sensing technology and Geographic Information System (GIS). Multitemporal satellite image data is used to identify types of land cover, such as forests, agricultural land, built land, and open land, over a period of time. Spatial analysis is carried out to determine the pattern of change and the factors that affect it. The results of the analysis showed that there was a significant change in land conversion, with the conversion of forest areas into plantations, rice fields, and built-up land. Despite this, most of the forest area has been preserved thanks to natural regeneration factors and community-based management. In addition, some plantation areas have changed their function to rice fields and built land, while savanna areas are relatively stable. These changes have the potential to affect the quality of ecosystems and the hydrological cycle of the region. The success of Aik Berik Village in maintaining forests and springs that are vital to the community shows the importance of sustainable and community-based land management.

APLIKASI PUPUK KOHE KAMBING YANG DIFERMENTASI DENGAN BIOAKTIVATOR Streptomyces sp. DALAM MENGENDALIKAN PENYAKIT BERCAK UNGU DAN MATI PUCUK PADA TANAMAN BAWANG PUTIH (Allium sativum L)
type: item
description: This study aims to determine whether the application of fermented goat manure with Streptomyces sp. bioactivator can control purple blotch (Alternaria porri) and top dieback (Phytophthora porri) diseases in garlic plants (Allium sativum L). The research was conducted at the Microbiology Laboratory of the Faculty of Agriculture, University of Mataram, and on a farmer's paddy field located in Sembalun Bumbung Village, East Lombok Regency. The study was carried out from May to November 2024. The experimental design used in this study was a Completely Randomized Design (CRD) consisting of six treatments: P0 (no fertilizer), P1 (goat manure without bioactivator), P2 (goat manure + SH isolate), P3 (goat manure + BSi isolate), P4 (goat manure + BSc isolate), and P5 (goat manure + SH isolate + liquid SH). Each treatment was repeated six times, resulting in 36 experimental units/plots. The data were analyzed using Analysis of Variance (ANOVA) at a 5% significance level, followed by the Honest Significant Difference (HSD) test at a 5% significance level. The results showed that applying fermented goat manure with Streptomyces sp. bioactivator affected the growth of garlic plants but did not affect the yield of garlic plants (Allium sativum L). The treatment with goat manure + BSi isolate (P3) showed the highest value in plant growth, while the treatment with goat manure + SH isolate + liquid SH (P5) showed the highest yield. Meanwhile, the incidence of purple blotch disease was not affected by the application of fermented goat manure with Streptomyces sp., but it successfully reduced the incidence of top dieback disease in garlic plants.

Sifat Mekanik Edible Film Berbasis Protein dengan Penggunaan Konsentrasi Plasticizer Sorbitol yang Berbeda
type: item
description: Edible film is a type of biodegradable packaging that can be an alternative to food packaging material to reduce environmental damage and maintain food product’s shelf life, quality, and safety. This research aims to determine the effect of the mechanical properties of protein-based edible film using different concentrations of sorbitol plasticizer on edible film thickness, gelation time, and film microstructure. To make edible films, the research material consists of sorbitol, whey protein, gelatin, distilled water, and silica gel. The research was conducted using a completely randomized design with three sorbitol plasticizer treatments consisting of P1:35%, P2:40%, P3:45%, and three replications. The data were analyzed using Analysis of Variance (ANOVA) and continued with the Duncan Multiple Range Test (DMRT) using the SPSS program. The research results showed that the use of sorbitol plasticizer with different concentrations gave a very significant difference (P<0.01) to P1 and P3, but P2 was not significantly different from the thickness of the edible film. The gelation time did not make a difference (P>0, 05), which is real, but adding different sorbitol to the edible film microstructure can produce varying microstructures. From the research results, the average values for edible film thickness are 0.053, 0.078, and 0.113 mm, while the gelation time produces average values of 19.33, 13.33, and 19 minutes. This research concludes that using different sorbitol concentrations provides a very significant difference in film thickness; however, unlike the gelation time, which does not make a difference, the microstructures produce varying microstructures.
