This study aims to determine the effect of storage periods that doesn’t have a negative effect on the physical characteristics of wafer complete ration based on cabbage waste with molasses adhesive. The material used consists of a source of fiber and concentrate with a balanced ratio (50:50). This study used a completely randomized design (CRD) with 4 treatments, namely: WRK-0 (without storage/control), WRK-2 (2 weeks storage), WRK-4 (4 weeks storage), WRK-6 (6 weeks storage) each treated 5 times. The observed variables were density, specific gravity, and water absorption. Analysis of the data using analysis of variety (ANOVA) and if there is a significant difference with the observed changes using the Orthogonal Polynomial (PO) test. The results showed that storage time had a very significant (P<0.01) linear effect on water absorption (260-279%) with the equation Y= 259.1 + 3.3X and R2 = 0.981 but had no significant effect (P> 0.05) to the value of wafer density (0.62-0.65 g/cm3) and specific gravity (1.12-1.22 g/mL). Based on the results of the study, it was found that storage for up to 6 weeks didn’t have a negative effect on the physical characteristiscs quality of water complete ration based on cabbage waste with molasses adhesive.

Pseudomonas fluorescens is plant growth promoting rhizobacteria (PGPR) often inoculated on plants as natural biocontrol agent capable of protecting the plants from soil-borne pathogens. Chemotactic motility allows populations of P. fluorescens to rapidly search for nutrients and is an important factor determining their competitive success to colonize plant root. Therefore, we investigated various glucose concentrations from 0% to 1% (w/v) to enhance chemotactic motility and growth of this rhizobia. Chemotactic motility was evaluated using swim plate assay and bacterial growth was measured using UV-Vis Spectrophotometer in LB and M9 medium. Glucose with low concentration (0.05%) showed to have optimum response in P. fluorescens chemotactic motility with colony diameter 38.3 mm in LB medium and 12.8 mm in M9 medium. Highest growth of P. fluorescens was seen in control condition of LB medium reaching a peak at 0.0246 OD600 (~Â±1,44x107 CFU ml-1 ) while growth in M9 medium supplemented with 1% glucose was just slightly lower with 0.0227 OD600 (~Â±1,32x107 CFU ml-1). Glucose in high concentration showed to repress chemotactic motility and first growth phase of P. fluorescens in LB medium due to catabolite repression.

Mangrove ecosystem is a coastal wetland has biodiversities such as flora, fauna, and microorganisms. Microorganisms are an importants component in the mangrove ecosystem and have many roles, including source the nutrition, decomposer, and a source of biotechnology products. Cellulolytic bacteria are a group of cellulase-producing bacteria capable of breaking down cellulose into glucose monomers. This study aims to screen and determine the diversity of cellulolytic bacteria from the mangrove ecosystem. The research method has been experimental by exploring the cellulolytic bacteria in soil and sediment from the mangrove ecosystem. Three sampling locations were selected such as the litter soil, soil in the root, and soil in the tidal area. The screened of potential bacteria-producing cellulase was obtained by bacteria growth on Carboxy Methyl Cellulose (CMC) agar medium. The isolates were cultured for 48 hours at 37°C. Then, the bacteria that produced the cellulolytic activity were characterized by morphological and physiological characteristics. The results were adjusted according to Bergey's Manual of Determinative Bacteriology. The determination showed that six isolates had the same characteristics as Bacillus, Cellulomonas, Lactobacillus, and Micrococcus. The cellulolytic activity index showed that three isolates were sequentially MS06 (9,73), MS03 (6,30), and MS08 (5,41).

This study evaluated how packaging materials (PM) and storage duration (SD) influence the physical properties of mantangan-based complete wafers (MbCW). The MbCW formulation consisted of 44% Merremia peltata, 16% Brachiaria mutica, and 40% concentrate. Ingredients were ground (2 mm), homogenized, steamed, and pressed to produce wafers. A 4 × 3 factorial completely randomized design assessed four PM types (WP: no packaging, PL: plastic, CB: cardboard, PS: plastic sack) and three SD levels (30, 60, and 90 days). Statistical analyses revealed significant PM × SD interactions (p < 0.01) for moisture content, impact resistance, and water absorption. SD alone affected density, specific gravity, shrinkage, and fungal concentration. Moisture content and water absorption increased over time, while plastic packaging uniquely improved impact resistance with extended storage. Other packaging types showed decreased impact resistance. Plastic packaging demonstrated superior performance, preventing fungal growth for up to 90 days, with only 1.06% mould at this time, compared to 4.43% without packaging. The effective shelf lives were 57, 54, 53, and 43 days for PL, CB, PS, and WP, respectively. In conclusion, plastic was the optimal packaging material for MbCW storage.

Tujuan dari penelitian ini adalah untuk mengetahui perbedaan lama waktu perendaman terhadap hasil tangkapan alat tangkap rawai (long line) di Kecamatan Nipah Panjang Kabupaten Tanjung Jabung Timur. Penelitian ini dilaksanakan di Kelurahan Nipah Panjang I Kabupaten Tanjung Jabung Timur pada tanggal 3 Juni 2021 sampai 30 Juni 2021. Metode yang digunakan adalah eksperimental dengan analisis data menggunakan uji t. Hasil penelitian menunjukkan bahwa perbedaan lama waktu perendaman 5 jam berpengaruh nyata (P <0,05) terhadap jumlah dan berat hasil tangkapan dibandingkan lama waktu perendaman 3 jam. Untuk jumlah pada perendaman 5 jam (113 ekor) sedangkan 3 jam (70 ekor). Untuk berat pada perendaman 5 jam (67,87 kg) sedangkan 3 jam (44,12 kg). Berdasarkan hasil penelitian dapat disimpulkan bahwa lama perendaman 5 jam terhadap hasil tangkapan dengan alat tangkap rawai lebih banyak dari lama perendaman 3 jam dengan hasil tangkapan yang didapat adalah ikan baung (Mystus nerumus), ikan sembilang (Plotosus canius), dan ikan duri (Hexanematichthys sagor).
