Abstract

The common bean is a functional food rich in nutrients and bioactive compounds that support good health. Improving common bean yield is essential for enhancing nutrition within communities. This study examined the effects of compost tea, ascorbic acid, and their combination on the productivity and antioxidant activity of upright common beans. The experiment involved six treatments, including a control (water spraying) (P1), ascorbic acid (P2), manure compost tea (P3), BSF larvae production residue (BSFR) compost tea (P4), manure compost tea and ascorbic acid (P5), and BSFR compost tea and ascorbic acid (P6). All treatments, except P6, showed significant differences in productivity. P2 recorded the highest yield at 8,13 tons/ha/cycle and increased productivity by 19,03%, followed by P5 (9,22%) and P3 (3,95%) compared to P1 (control). P4 had a slight reduction in productivity by 3,95% than P1. A combination of compost tea and ascorbic acid increased productivity by 5,07% for P5 and 4,63% for P6 compared to the treatment without combination with ascorbic acid. P2 had the lowest IC50 value, 17,46 µg/ml, indicating the highest antioxidant activity. Compost tea and ascorbic acid combined reduced the IC50 value by 23,12% for P5, but P6 increased it by 32,59%. P5 improved the antioxidant activity of common bean pods when combined with compost tea and ascorbic acid, while P6 demonstrated a better effect without the combination. P3 and P6 had higher IC50 values than the control but lacked the potential to improve the antioxidant activity of common bean pods.

Abstract

Pertanian berkelanjutan dengan pendekatan permakultur yang diinisiasi oleh Bill Mollison dan David Holmgren pada tahun 1970-an merupakan solusi yang menarik dalam merespon kerusakan lingkungan dan aspek sosial akibat Revolusi Hijau. Tujuan dari penelitian ini untuk mengidentifikasi penerapan prinsip permakultur sebagai desain sistem pertanian berkelanjutan, menganalisis manfaat model permakultur, dan menentukan strategi pengembangan model permakultur sebagai sistem pertanian berkelanjutan. Data diperoleh dari responden melalui wawancara dan observasi, kemudian diolah secara deskriptif dan diperkuat dengan data sekunder yang diperoleh dari studi pustaka. Hasil dari penelitian menunjukkan bahwa 12 prinsip permakultur telah diimplementasikan di Rumah Kayu Permakultur melalui kegiatan produksi, edukasi, dan wisata. Manfaat penerapan model permakultur yang ditunjukkan oleh aspek sosial yaitu dapat meningkatkan kualitas kelangsungan hidup manusia dalam jangka panjang melalui ketahanan pangan, pada aspek ekonomi terjadi efisiensi biaya pada proses sistem yang mampu memberikan peningkatan kualitas lingkungan. Berdasarkan hasil analisis SWOT, ditetapkan strategi alternatif dalam pengembangan model permakultur sebanyak 8 strategi yang terdiri dari pengembangan permakultur pada aspek produksi, aspek edukasi, dan aspek wisata sebagai desain sistem pertanian berkelanjutan. Kata kunci: pertanian berkelanjutan, prinsip permakultur, desain permakultur, pemulihan ekosistem, produk organik.

Abstract

Agriculture plays a crucial role in the economy of Bandung Regency, particularly in Ciparay and Rancaekek Districts. However, challenges such as land conversion, climate change, and market fluctuations affect agricultural productivity and sustainability. In response, the Bandung Regency Government implemented the Sibedas Farmer Card Program, aimed at improving farmers' welfare through input subsidies and access to agricultural insurance. This study examines the relationship between the Sibedas Farmer Card policy, livelihood capital, coping behavior, and livelihood resilience among rice farmers. A quantitative approach using SEM-PLS was applied, involving 72 rice farmers as respondents. The findings indicate that the Sibedas Farmer Card policy does not significantly influence livelihood capital (β = -0.168, P = 0.135). However, livelihood capital has a significant effect on coping behavior (β = 0.713, P = 0.000) and livelihood resilience (β = 0.346, P = 0.012). Additionally, coping behavior significantly impacts livelihood resilience (β = 0.536, P = 0.000). These results suggest that strengthening livelihood capital enhances farmers' adaptability and resilience. While the program has been implemented, its effectiveness in improving farmers' livelihood capital remains limited. To optimize its impact, policymakers should expand farmers' access to training, technology, and financial support. Therefore, well-directed agricultural policies are essential to enhancing the sustainability of the agricultural sector in Bandung Regency.
