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.
