Abstract

Kabupaten Jember merupakan salah satu sentral penghasil tembakau tertinggi di Jawa Timur dan pada tahun 2018 produksinya mencapai 163,267,5 ton. Produksi tanaman tembakau menghasilkan limbah organik yang berbahaya yaitu nikotin. Nikotin merupakan alkaloid beracun aktif, berminyak, tersusun atas unsur karbon, hidrogen, nitrogen, dan sangat larut terhadap alkohol, eter, minyak tanah, dan air. Kelarutannya berisiko mengalami leaching (pencucian) selama masa penyimpanan limbah tembakau. Hal tersebut mengakibatkan nikotin yang tercuci dapat mengalir ke dalam badan air sehingga membahayakan makhluk hidup dan lingkungan. Beberapa mikroorganisme mampu mendegradasi nikotin dengan memanfaatkannya sebagai sumber karbon dan nitrogen untuk pertumbuhannya, salah satunya aktinomisetes. Penelitian ini bertujuan untuk mendapatkan aktinomisetes asal rhizosfer tembakau yang memiliki aktivitas pendegradasi nikotin dan besar daya degradasinya. Penelitian dilakukan skrining 23 isolat aktinomisetes pendegradasi nikotin dengan indikator tumbuh aktinomisetes pada media hingga terdapat 3 isolat terpilih, uji degradasi nikotin pada media cair dengan metode titrasi dan daun tembakau dilakukan di Balai Pengujian dan Sertifikasi Mutu Barang (BPSMB) kota Surakarta, dan identifikasi morfologi secara mikroskopis isolat terpilih menggunakan cover slide method. Hasil skrining menunjukkan bahwa 5 isolat memiliki kemampuan tumbuh, 13 isolat mumpu tumbuh baik, 3 isolat tumbuh lebih baik dan 2 isolat tidak tumbuh. Isolat yang terpilih yaitu ATG 60, ATG 68, dan ATG 69 tumbuh lebih baik pada media nikotin (NIM). Daya degradasi nikotin media cair dan daun tembakau pada ATG 60 (2,33% dan 30,56%); ATG 68 (2,53% dan 31,16%); dan ATG 69 (2,1% dan 25,82%). Identifikasi struktur spora menunjukkan masing-masing isolat adalah Saccharopolyspora sedangkan ATG 68 dan 69 genus Streptomyces.

Abstract

Caffeine-degrading bacteria can be used as agents to degrade caffeine, thereby reducing the concentration of caffeine in organic waste. The decomposition process is carried out by a single bacterium or a consortium of bacteria. Caffeine-degrading bacteria from Sempol, Bondowoso, namely Acinetobacter gerneri KAFS 47, Paracoccus denitrificans KAFS 16 and Pseudomonas plecoglossicida KAFS 34, could be used as a bacterial consortium to promote caffeine degradation. The aim of this study was to analyze associations between caffeine-degrading bacteria isolates, bacterial resistance to antibiotics, growth patterns, and caffeine degradation of a consortium of caffeine-degrading bacteria, and the correlation of bacterial growth with caffeine degradation. The research method used is an analysis of the association between isolates, the development of bacterial consortium growth patterns, and their analysis based on antibiotic resistance, patterning of caffeine degradation, and correlation test (Pearson) of bacterial growth with caffeine degradation. The result of the association test between bacteria showed that the three bacteria had the potential to be used as a consortium of caffeine-degrading bacteria. A. Gerneri, P. denitrificans, and P. plecoglossicida were resistant to the antibiotic cefixime (100 ppm), erythromycin (50 ppm), lincomycin (50 ppm), metronidazole (50 ppm), and sanprima (50 ppm). The growth of the bacterial consortium (54.779 CFU/mL) was higher than that of P. plecoglossicida (49.277 CFU/mL) and lower than that of A. gerneri (93.481 CFU/mL) and P. denitrificans (84.940 CFU/mL) in incubation time of 4 days. However, the consortium of bacteria and P. plecoglossicida were able to degrade caffeine 24 hours faster (3 days) than the other two single isolates (4 days) to degrade 2.5 g/L caffeine in media to 0%. Bacterial growth due to caffeine degradation has a perfect correlation value (>0. 950) and is negative.

Abstract

Porang tuber (Amorphophallus muellerii BI.) Is a type of tuber that has a high enough glucomannan content of 67%. Glucomannan is very difficult to digest by humans directly so it takes the role of probiotics. L. casei bacteria FNCC0900 as a probiotic agent capable of utilizing glucomannan as a carbon source for growth. The purpose of this study was to determine the growth pattern and changes in environmental factors, namely the pH value of the probiotic bacteria L. casei FNCC0900 growth medium. The parameters in this study consisted of the highest cell density, generation time and pH value changes in Glucose Yeast Peptone Liquid Media, Porang Boiled Water Media and Porang Flour Liquid Media using the drop plate method which had 4 repeated calculations. Porang Boiled Water Liquid Media has a faster log phase period with a higher cell density than Porang Flour Liquid Media, but the shortest generation time is found in Porang Flour Liquid Media with the highest number of generations. L. casei FNCC0900 bacteria are more able to reduce the pH of Glucose Yeast Peptone Liquid Media compared to porang tuber-based media, so in this case L. casei FNCC0900 can be stated to be able to grow on porang tuber-based media with growth patterns, generation time, cell density and pH value. which varies.

Abstract

Tanaman pangan di Indonesia sangat beragam termasuk diantaranya padi, jagung dan ubi kayu. Namun lahan pertanian di Indonesia semakin sempit seiring dengan laju pertumbuhan penduduk yang semakin tinggi. Lahan kering (sub optimal) di Indonesia masih banyak yang belum dimanfaatkan, yang sebenarnya bisa dioptimalkan sebagai lahan pertanian. Tanaman pangan yang memiliki tingkat ketahanan lebih tinggi terhadap lahan kering adalah tanaman ubi kayu, sehingga berpotensi untuk ditanam pada lahan kering. Tahap pertama pemuliaan tanaman ubi kayu adalah mengetahui karakterisasi gen pada tanaman tersebut salah satunya yaitu WIN1. Metode pertama yang dilakukan adalah isolasi DNA daun ubi kayu varietas Adira 1 dan Malang 6, kemudian amplifikasi dengan PCR, dan analisis sekuensing. Hasil menunjukkan tanaman ubi kayu Adira 1 memiliki asam amino yang sama dengan kultivar am560-2 yang terdapat pada GenBank, sedangkan pada varietas Malang 6 terdapat satu asam amino yang berbeda. Hal tersebut dapat dipengaruhi oleh adanya mutasi gen pada varietas ubi kayu serta perbedaan kandungan HCN pada ubi kayu pangan varietas Adira 1, dan ubi kayu industri varietas Malang 6.

Abstract

The use of incomplete or imbalanced data in ecological modelling and conservation planning can lead to inaccurate predictions due to limitations in detection methods. Therefore, obtaining comprehensive and precise empirical data on species presence and availability, particularly prey species is essential. This study aims to: (1) identify the presence of Javan leopards and their potential prey species, and (2) estimate the relative abundance indices (RAI) of each prey species. Using camera trap data from the Meru Betiri National Park (MBNP) survey conducted in 2024, we recorded 24 species, including the Javan leopard, and identified seventh potential prey species. We estimated relative abundance of each potential prey species was determined by dividing the number of individuals recorded in independent photos or videos by the total number of trap days and multiplied by 100. The result of RAI analysis indicated that the most abundant prey species in the study area was the long-tailed macaque, with an RAI value of 44.16 individuals per 100 trap-days, banteng was the least frequently detected species, appearing in only three independent images, with an RAI value of 0.23. The presence of Javan leopards, a charismatic flagship species, highlights the ecological significance of this area and provides valuable data for biodiversity management, serving as a foundation for future research and conservation efforts.

Abstract

Xilan is a polysaccharide that can be used as a substrate for producing xylanase. Xylan can be obtained from processing xylan-rich agricultural waste such as corn cobs, which contain 12.4% xylan. Xilan can be hydrolyzed into xylose and xylooligosaccharide (XOS) using the enzyme Xilanase. Actinomycetes have dominant xylanolytic species, Actinomyces ATG 70 has semi-qualitative xylanolytic ability with an enzyme activity index of 3.21±0.55 in xylan media. This study was conducted by extracting xylan from corn cobs, rejuvenating Actinomyces ATG 70, preparing the inoculum, creating a standard curve, producing xylanase with pH optimization of the medium, testing xylanase activity, characterizing the pH and temperature of crude xylanase, and identifying the morphology and biochemical characteristics of Actinomyces ATG 70. Optimization of the pH of the xylanase production medium was achieved at pH 8, with xylanase activity of 10.07±0.13 U/mL. The crude xylanase was characterized for pH and temperature effects, and the optimal pH for crude xylanase was found to be pH 6 with xylanase activity of 7.64±0.66 U/mL, and the optimal temperature was 50°C with xylanase activity of 11.17±0.33 U/mL. The identification results showed that Actinomyces ATG 70 belongs to Gram-positive bacteria, with a positive catalase test, white colonies, cream-colored aerial mycelium, and cream-colored pigmentation. The spore structure consists of long chains of conidia, streptococcus-shaped cells, and can form aerial mycelium, thus the isolate belongs to the genus Streptomyces.
