Abstract

Adoption of superior varieties is a strategy for maintaining regional food production. Sarinah rice cultivar is a type of rice that is resistant to several types of pests and plant diseases. This variety is cultivated by farmers in several areas in West Java Province. This study aims to investigate: (1) the association between rice cultivation technology and farming performance; (2) the relationship between farmer group dynamics and farm performance; and (3) the joint effects of rice cultivation technology and farmer group dynamics on the overall performance of rice farming. This study employed a survey method, with the analytical unit consisting of farmers who are members of farmer groups cultivating Sarinah rice cultivar in Bojongpicung Subdistrict, Cianjur Regency, West Java Province. Sampling technique was carried out using a census approach, involving a total of 30 respondents. Collected data were analysed using path analysis, with analytical procedures aligned with results of hypothesis testing. Results of study indicate that adoption of rice cultivation technology is significantly associated with farming success, accounting for 30.4% of variation. In comparison, farmer group dynamics show a stronger significant association, explaining 64.0% of the variation. Among two factors, farmer group dynamics exhibited strongest relationship with farming success. Rice cultivation technology and farmer group dynamics, when considered simultaneously, have a significant combined effect on farming success, accounting for 94.4% of the variation. Remaining 5.6% is attributed to other factors that were not examined in this study.

Abstract

Duku production and productivity in Jambi Province remain low because the existing plants are old, and cultivation technology is not precise. Efforts to overcome this problem include rejuvenation using superior seeds obtained through propagation of shoot grafting. Intensification can be done through fertilization. One fertilizer option is goat manure compost combined with NPK. The purpose of this research is to develop a technology package to accelerate duku growth in ultisols. This research was conducted in the Faculty of Agriculture’s experimental garden for 4 months on 1-year-old duku plants. The design used in this study was a randomized block design (RAK) with one factor, namely the dose of goat compost fertilizer consisting of five levels, namely 100% NPK (306g); 5 kg Goat Compost + 75% NPK (229.5g); 10 kg Goat Compost + 50% NPK Fertilizer (153g); 15 kg Goat Compost + 25% NPK (76.5g); 20 kg Goat Compost Fertilizer. Observations were made on the variables of increase in plant height, increase in stem diameter, increase in the number of leaf tillers, bud break time, and increase in the number of branches. The results showed that goat compost combined with NPK can substitute for NPK fertilizer. The application of 15 kg of goat manure compost with 25% NPK content showed the best combination for supporting the growth of immature Duku plants.

Abstract

Perubahan iklim menjadi isu penting dan menjadi perhatian sekaligus tantangan semua sektor. Pada sektor pertanian, perubahan iklim mengakibatkan terjadinya ketidakpastian hasil produksi, bencana hama dan penyakit tanaman serta kekeringan lahan. Tanaman padi sawah termasuk tanaman yang memiliki ketergantungan tinggi terhadap air, mengingat 45,7% lahan sawah di Indonesia bersifat tadah hujan perubahan iklim menjadi perhatian serius. Upaya dalam mengendalikan kondisi tersebut perlu dilakukan oleh petani seperti melakukan tindakan-tindakan resilien sehingga dampak perubahan iklim dapat dikontrol. Berangkat dari permasalahan tersebut penelitian ini akan mengkaji bagaimana tindakan resiliensi petani padi sawah dalam menghadapi perubahan iklim di Kota Bengkulu. Penelitian ini dilaksanakan di Kota Bengkulu pada 2-14 September 2025 dengan menggunakan analisis kuantitatif deskriptif. Hasil penelitian menunjukkan bahwa modal fisik merupakan komponen modal utama yang memberikan kontribusi paling signifikan terhadap perubahan iklim, sedangkan modal sumber daya alam menjadi komponen modal dengan kontribusi terendah dalam menghadapi perubahan iklim oleh petani. Capacity of Learning merupakan bentuk tindakan resiliensi yang memiliki nilai tertinggi, yang mengindikasikan bahwa kegiatan penyuluhan dan pelatihan memberikan dampak signifikan terhadap kemampuan petani dalam menghadapi perubahan iklim. Oleh karena itu, penelitian ini merekomendasikan peningkatan frekuensi pertemuan dalam aktivitas pelatihan dan pembelajaran bagi petani guna membangun pengetahuan yang dapat meningkatkan kemampuan mereka dalam mengendalikan dampak perubahan iklim.

Abstract

Tryptophan and pH are environmental factors that convincingly influence microbial growth, metabolism, and metabolite production. This study aimed to find out how tryptophan and pH affect the production of Indole-3-acetic acid (IAA) by Bacillus spp. in Nutrient Broth (NB) medium. A Completely Randomized Design (CRD) with six treatments and three replications was used. The confirmation bacterial strains were Brevibacillus agri, Brevibacillus borstelensis (2 isolates), and Bacillus subtilis. The NB medium was adjusted to four pH levels (5, 6, 7, and 8) and supplemented with different concentrations of tryptophan: 0, 102, 150, 300, 450, and 600 mg/ml. The results after incubated showed that Brevibacillus agri was detected the highest IAA content at pH level 7.0 with 600 mg/ml of tryptophan (204 µg/ml). Whereas Brevibacillus borstelensis and Bacillus subtilis caused the maximum of IAA contents at pH level 8.0 with 600 mg/ml of tryptophan at 79.31 µg/ml and 35.82 µg/ml respectively.

Abstract

Salah satu upaya peningkatan produksi padi dapat ditempuh melalui intensifikasi lahan diantarnaya melalui pemanfaatan lahan salin. Tanah salin mengandung kadar garam yang dapat menyebabkan kerusakan sel tanaman, penurunan fotosintesis, serta penurunan efisiensi air dan nutrisi. Hal ini menjadikan produksi padi di tanah salin kurang optimal jika tidak diimbangi dengan upaya perbaikan tanah dan manajemen nutrisi yang tepat. Kegiatan dilakukan di Desa Ujung Gagak, Nusa Kambangan, Kabupaten Cilacap melalui kegiatan farmer action research. Kegiatan ini bertujuan untuk mengetahui pengaruh penggunaan formula pupuk hayati majemuk terhadap beberapa varieatas pada kondisi lahan salin. Pemupukan mempengaruhi keparahan gejala tanaman serta tinggi tanaman akibat salinitas tanah di lapangan pada fase vegetatif. Varietas memberikan perbedaan respon yang signifikan terhadap tingkat kehijauan daun, keparahan gejala tanaman akibat cekaman salin, serta jumlah anakan baik pada stadia vegetative dan generatif. Varietas lokal Ngaos Mawar pertumbuhannya lebih baik dilihat dari kehijauan daun, keparahan gejala keracunan salinitas yang rendah dibandingkan dengan varietas lainnya. Varietas Ngaos Mawar kategori tahan, Inpara 08 dan varietas Inpari 34 kategori moderat-rentan, sedangkan Inpara 09 termasuk kategori rentan berdasarkan pengamatan lapangan. Pemberian pupuk hayati majemuk dan tanpa pemberian pupuk hayati majemuk tidak mempengaruhi jumlah populasi serangga. Jumlah populasi jenis serangga (guild) menunjukan perbedaan yang signifikan. Jumlah musuh alami lebih banyak dibandingkan serangga hama dan serangga netral. Pemberian pupuk hayati majemuk menunjukan keanekaragaman arthropoda sedang, dengan kondisi ekosistem yang cukup seimbang. Pemanfaatan lahan salin juga memerlukan perhatian waktu tanam tepat dan serempak sehamparan untuk mengantisipasi serangan hama

Abstract

Cellulase (EC 3.2.1.4) is an enzyme capable of degrading cellulose into glucose, cellobiose, and cellooligosaccharides. Cellulase enzymes can be produced by cellulolytic fungi originating from various environments, including the Avicennia marina mangrove ecosystem. However, most previous studies have primarily focused on the isolation and screening of cellulolytic fungi without systematically evaluating the influence of carbon sources on cellulase production and activity. Furthermore, research integrating enzyme activity assays with molecular identification of fungal isolates from mangrove litter remains limited. Therefore, this study aims to isolate cellulolytic fungi from mangrove litter capable of producing cellulase enzymes, test the influence of various carbon sources on enzyme activity, and identify fungal isolates using the Internal Transcribed Spacer (ITS) housekeeping gene. We used the spread plate technique to isolate cultivable fungi. The cellulolytic activity of the fungal isolates was tested qualitatively using Congo red staining and analyzed quantitatively using the 3,5-dinitrosalicylate (DNS) method with various carbon sources, such as 1 percent Carboxymethyl Cellulose (CMC), 1 percent cellobiose, Potato Dextrose Broth (PDB), and a combination of 5 percent CMC and 5 percent cellobiose. Enzyme activity assays were performed using a spectrophotometer at a wavelength of 580 nm. This study obtained 10 purified and cultivable fungal isolates from three samples collected from two sampling sites. Screening for cellulolytic fungi identified two isolates capable of forming clear zones around their colonies: isolates C3.3 and A3.3. Quantitative cellulase activity assays indicated that the optimal carbon source for cellulase production was a combination of 5 percent CMC and 5 percent cellobiose for isolate A3.3, with peak activity occurring on day 3 at 46,736.19 U/mL and a pH of 6.11. Molecular identification results showed that isolate C3.3 had 100 percent similarity to Aspergillus aculeatus, while isolate A3.3 had 99 percent similarity to Penicillium javanicum.

Abstract

Kegiatan pengolahan dilakukan sebagai upaya pemanfaatan potensi kedelai melalui proses distribusi, serta penjualan tempe sebagai bagian dari aktivitas usaha. Banyak home industri yang menjalankan pengolahan tempe, namun belum menerapkan integrasi vertikal karena produk tersebut dapat langsung dipasarkan kepada konsumen akhir. Penentuan sampel dilakukan berdasarkan informasi yang diperoleh dari pedagang pengumpul kedelai, pedagang besar, serta para pelaku usaha dengan menggunkan Teknik Sampling sensus, responden pada penelitian ini yaitu seluruh pelaku rantai nilai pemasaran kacang kedelai. Cara menganalisis data dilakukan dengan pendekatan yang menjelaskan, baik dari segi kualitas maupun angka, terhadap jalur rantai nilai pemasaran kacang kedelai dan aliran pemasaran produk tempe. Sedangkan nilai tambah dianalisis menggunakan metode Hayami, sedangkan kinerja pemasaran produk tempe diukur berdasarkan marjin, tingkat keuntungan, dan efisiensi pemasaran. Hasil penelitian menunjukkan bahwa rantai nilai untuk pemasaran kedelai berjalan dalam satu jalur, dimulai dari pengumpul hingga konsumen, selanjutnya ke home industry, kemudian ke pedagang retail hingga sampai kepada konsumen akhir. Proses nilai tambah yang tercipta pada usaha home industri telah memberikan nilai tambah produk tempe senilai Rp235.068,-/kg. Kinerja pemasaran yang terbentuk dari produk tempe pada usaha home industri yakni home industri → retail → konsumen akhir, dan saluran pemasaran produk tempe dapat dikatakan telah efisien secara optimal.

Abstract

Hotong (Setaria italica), a millet crop native to Buru Island in eastern Indonesia, has the potential to diversify local food crops and support smallscale industries. Hotong has agronomic advantages as an alternative food to replace rice and wheat, rich in carbohydrates, protein, and fiber, in addition, this plant is drought-resistant and thrives on marginal land. Hotong has great potential to be processed into various high-value products. However, its development remains constrained by informal seed systems, limited postharvest facilities, weak farmer institutions, and rice-oriented food policies. This study aimed to analyze internal and external strategic factors affecting hotong agribusiness and to determine priority strategies for its development. Field research was conducted in Waenewen Hamlet, Labuang Village, South Buru Regency, Indonesia, involving 60 hotong farming households, village government, representatives of farmers group involved in product processing and marketing. agricultural extension officer., and local processors. Primary data were collected through structured questionnaires, interviews, and focus group discussions, while secondary data were obtained from official and documentary sources, including the Labuang Village monograph, Namrole District profile, statistical publications from BPS, local government documents, food diversification policy reports, and relevant. Data were analyzed using internal factor evaluation (IFE), external factor evaluation (EFE), SWOT matrix, Quantitative Strategic Planning Matrix (QSPM), reliability testing, and sensitivity analysis through ±10% weight adjustment. The results indicate that hotong agribusiness has moderate internal capacity and external opportunity. Certified seed system development emerged as the highest priority strategy, followed by policy alignment with food diversification programs and research–SME collaboration. Sensitivity analysis showed that the top-ranked strategies remained stable under moderate weight adjustment. This study contributes to the development of a strategic planning framework for indigenous crop-based agribusiness systems in small-island contexts by integrating system-based agribusiness analysis, SWOT–QSPM prioritization, and robustness testing.
