Abstract

Appropriate land management has a long-term impact on soil performance and is believed to improve soil fertility. This study investigated the effect of eco-enzymes on soil nutrients and plant productivity of green mustard-peanut in inceptisol. The research was conducted from February to April 2025.  The experiment used a randomized block design (RBD) consisting of 5 treatments and replicated 3 times, so that there were 15 units, including N0 = without Eco-enzyme, N1 = Eco-enzyme 2cc/L. N2= Eco-enzyme 4cc/L, N3= Eco-enzyme 6cc/L, and N4= Eco-enzyme 8cc/L. The commodities used were green mustard (Brassica juncea L) and peanut (Arachis hypogaea Linn). Soil properties variables included soil pH, N-total, and P-available, while plant productivity variables included plant height, number of leaves, leaf area, fresh weight, and pod production. The results showed that the concentration of eco-enzymes had a significant effect on N-total, P-available, green mustard plant height, and peanut plant height. However, eco-enzyme concentration had no significant effect on soil pH, number of green mustard leaves, green mustard fresh weight, green mustard leaf area, number of peanut branches, and peanut pod production. The lowest production of green mustard was 0.85 tons/ha, and the highest was 3.29 tons/ha. While the lowest production of Peanut pods was 4.3 tons/ha and the highest was 6.67 tons/ha.

Abstract

Dalam rangka peningkatan produksi pertanian sudah saatnya pengelolaan pertanian diarahkan pada input pemupukan yang ramah lingkungan dan pada lahan-lahan dengan produsktifitas yang rendah terutama dengan kondisi kesuburan rendah baik biofisik dan kimia. Pengelolaan lahan pertanian juga harus mampu memanfaatkan sisa hasil produksi yang tidak terpakai (limbah) dari tanaman maupun hewan untuk dijadikan sebagai pupuk organik. Dalam kegiatan ini sisa limbah pertanian yang digunakan adalah sebagai pupuk organik adalah pupuk kandang ayam, pupuk kandang sapi dan serasah dari cengkeh. Sedangkan media tanah pasir digunakan karena memiliki sifat kesubururan yang rendah baik biofisik dan kimia. Tujuan kegiatan ini adalah memanfaatkan sisa kotoran hewan sebagai pupuk organik dan tanah pasir dalam meningkatkan pengetahuan dan ketrampilan dalam bercocok tanaman sayuran. Sasaran peserta dalam kegiatan ini adalah kelompok tani atau petani yang mengusahakan budidaya tanaman sayuran dengan pendekatan metode penyuluhan dan diskusi mengenai budidaya tanaman serta aplikasi penerapan teknologi pertanian organik. Hasil kegiatan menunjukkan bahwa perlakuan pupuk kandang ayam, merupakan salah satu bahan organik tanah yang mampu memberikan produktifitas berat segar yang lebih baik dibandingkan dengan pupuk kandang sapi dan serasah cengkeh.

Abstract

Pertanian sayuran di Desa Bobanehena, Kecamatan Jailolo, Halmahera Barat, masih menghadapi tantangan produktivitas rendah akibat ketergantungan pada pupuk kimia serta belum optimalnya pemanfaatan limbah organik. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan pengetahuan dan keterampilan petani dalam mengolah kotoran hewan dan limbah pertanian menjadi pupuk bokashi. Metode yang digunakan adalah pendekatan partisipatif, meliputi observasi, sosialisasi, pelatihan, pendampingan aplikasi, serta evaluasi. Sebanyak 22 petani sayuran terlibat sebagai peserta. Hasil kuesioner pra-pelatihan menunjukkan lebih dari 80% petani belum mengenal maupun menggunakan bokashi. Setelah pelatihan, 100% responden memahami konsep dan bahan, 90% mampu membuat bokashi secara mandiri, serta seluruhnya bersedia mengaplikasikan di lahan sayuran. Evaluasi lapangan menunjukkan bahwa bokashi meningkatkan pertumbuhan dan hasil tanaman sawi secara signifikan. Perlakuan 20 ton/ha menghasilkan tinggi tanaman 30,5 cm, jumlah daun 16 helai, dan berat segar 4,20 kg, jauh lebih tinggi dibanding kontrol 0 ton/ha (20,5 cm; 8 helai; 1,05 kg). Penerapan bokashi terbukti memberikan manfaat ekologis, ekonomi, dan sosial, sehingga berkontribusi pada pembangunan pertanian berkelanjutan berbasis sumber daya lokal.   Kata kunci: bokashi, pupuk organik, limbah pertanian, petani sayuran, pertanian berkelanjutan

Abstract

Social forestry is a national policy instrument intended to improve community welfare while maintaining forest sustainability. However, the success of social forestry is shaped not only by the issuance of permits, but also by the post-permit capacity of farmer groups to manage institutions, enterprises, and forest areas. This study aims to analyze the institutional capacity of KTH Ake Guraci and KTH Lestari Hutan Togafo after obtaining Community Forestry (HKm) permits and to formulate strategies to strengthen their capacity. The study was conducted in the working area of the Ternate-Tidore Forest Management Unit using a descriptive approach with qualitative and quantitative data. SWOT analysis was applied through IFAS, EFAS, Internal-External (IE), and SWOT matrices. The results show that both groups are in the medium internal and external categories. KTH Ake Guraci recorded an IFAS score of 2.29 and an EFAS score of 2.26, while KTH Lestari Hutan Togafo recorded an IFAS score of 2.39 and an EFAS score of 2.35. Both groups occupy cell V of the IE matrix and quadrant I of the SWOT matrix, indicating that aggressive growth-oriented strategies remain feasible. Capacity strengthening should therefore focus on institutional consolidation, NTFP-based enterprise development, human resource improvement, and stronger facilitation, partnerships, and market access in the post-permit phase.

Abstract

The Essential Ecosystem Area (KEE) of mangroves in Kao Village, North Halmahera Regency, covers approximately 300.92 ha and plays a significant ecological and socio-economic role. However, its utilization has not been optimally managed based on sustainability principles. This study aimed to analyze the biophysical characteristics and vegetation structure of the mangrove ecosystem and to formulate a landscape planning strategy for conservation-based mangrove ecotourism development. The research employed vegetation analysis using transect-plot methods to calculate density, frequency, dominance, and Important Value Index (IVI), ecotourism suitability analysis, and SWOT analysis to determine development strategies. The results indicated that the area is dominated by true mangrove species with high IVI values, reflecting their major role in ecosystem structure. Vegetation density ranged from dense to very dense in several zones, indicating relatively good ecosystem conditions. Suitability analysis showed that most areas are classified as suitable to highly suitable for mangrove ecotourism development. The recommended strategies include strengthening local institutions, providing environmentally friendly infrastructure, developing interpretative pathways, and enhancing community capacity through collaborative approaches. Landscape planning based on conservation zoning and limited utilization is proposed to maintain ecological and economic balance within the area.
