Abstract

This community service program aimed to empower oil palm farmers in Sialang Sakti Village, Siak Regency, by utilizing oil palm fronds as raw material for vermicompost production to support sustainable agriculture and the implementation of the Indonesian Sustainable Palm Oil (ISPO) standards. The main problem faced by the partner group was the accumulation of unutilized frond waste and the farmers’ limited knowledge of organic waste management. The program was conducted from July 27 to August 23, 2024, involving members of the Manunggal Sakti Farmers Group and student volunteers. The activities included socialization, technical training on vermicomposting, media maintenance and observation, harvesting and packaging of vermicompost, and field application on oil palm plantations. Data were collected through direct observation, laboratory analysis, and community satisfaction surveys conducted before and after the program using questionnaires. The results indicated a significant improvement in farmers’ knowledge and skills in producing and applying vermicompost. The final product exhibited desirable characteristics dark color, earthy odor, crumbly texture, and nutrient content meeting organic fertilizer standards. The program generated direct benefits by reducing palm frond waste and enhancing farmers’ awareness of organic waste utilization. In conclusion, the program successfully achieved its objectives in empowering the local community and improving waste management capacity. Although challenges such as limited time and production facilities were encountered, the strong enthusiasm of participants ensured the program’s sustainability through plans to establish a farmer-based vermicompost business unit.

Abstract

Lahan gambut memiliki peran penting dalam ekosistem, namun sangat rentan terhadap degradasi akibat perubahan penggunaan lahan dan kebakaran. Penelitian ini bertujuan untuk mengevaluasi karakteristik fisik tanah gambut pada penggunaan lahan kelapa dua tipe penggunaan lahan gambut di Pulau Burung, Indragiri Hilir, Riau, yaitu lahan perkebunan kelapa dan lahan gambut terbakar yang telah berkembang menjadi semak belukar. Contoh tanah diambil dari kedalaman 0–20 cm dan 20–40 cm, lalu dianalisis untuk parameter fisik tanah. Analisis deskriptif-komparatif menunjukkan bahwa lahan perkebunan kelapa memiliki sifat fisik tanah yang berbeda, dengan bobot isi rendah (0.18-0.11 g/cm³), kerapatan partikel <1 g/cm³, dan porositas tinggi (80–84%). Sebaliknya, lahan semak belukar bekas terbakar menunjukkan peningkatan bobot isi dan kerapatan partikel. Perbedaan ini mencerminkan dampak dari kebakaran, serta manajemen dari perkebunan kelapa. Hasil penelitian menekankan pentingnya pengelolaan lahan gambut yang berkelanjutan tanpa kegiatan pembakaran.

Abstract

Limited farmer knowledge of balanced fertilization and acidic paddy soil conditions contributed to the suboptimal rice productivity of the Rumbio Sarumpun Farmers Association in Benai District. This community service program applied participatory and andragogical approaches through participant identification, focus group discussions, pre-tests, technical training, demonstrations, field practice on demonstration plots, mentoring, post-tests, and field observations. The introduced technology consisted of pre-planting liming using dolomite and balanced NPK fertilization according to crop requirements and growth stages. The combined application of liming and balanced NPK fertilization resulted in better rice growth than the farmers’ previous practices, as indicated by improvements in plant height, productive tillers, leaf area, panicle number, filled grains, and 1,000-grain weight. Rice productivity increased by an average of 15–25%. The program also improved farmers’ knowledge and practical skills in soil fertility management and appropriate fertilizer application. However, the sustainable adoption of this technology remained constrained by limited access to agricultural lime and production costs. Continuous mentoring and support from agricultural extension officers, universities, and local governments were therefore required to promote wider and more sustainable implementation.
