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

Land degradation is one of the biggest challenges to agricultural sustainability in tropical regions, mainly due to the pressures of land intensification, climate change, and unsustainable soil management practices. Soil deterioration can occur in physical, chemical, and biological aspects, thereby reducing the soil's capacity to support agricultural productivity. This study aimed to evaluate the status of soil deterioration through a multi-parameter approach in the dryland ecosystem of North Halmahera, Indonesia. The parameters analyzed include solum thickness, surface stoniness, fraction composition, bulk density, porosity, water permeability, pH, electrical conductivity (EC), redox potential, and microbial population. The results showed that all points experienced degradation, with four points (T1, T2, T4, T5) classified as moderately deteriorated and the other four points (T3, T6, T7, T8) classified as severely deteriorated. The main factor of deterioration was very high salinity (29-50 mS/cm), far exceeding the critical threshold, which caused osmotic stress and ion toxicity to plants, low redox (100 mV), high bulk density (1.83-1.99 g/cm³), extreme porosity (>70%), and low microbial population (<10² CFU/g) at several points. However, the soil pH is relatively neutral (6.8-7.0), so it is not a limiting factor. The results of this study are used as reference material for sustainable land management to achieve the sustainable development goals.

Abstract

The Educational Forest in the Forest Management Area (KPH) Unit XIII, located in South Halmahera Regency, North Maluku Province, has the potential to be developed as a natural ecotourism area. One of the main functions of natural ecotourism is to preserve biodiversity and natural ecosystems in an area. However, available data on the potential of the educational forest environment for this purpose is still limited. Hence, this study was conducted with the aims of: 1) identifying the potential of an Educational Forest area; 2) analysing the level of suitability of the ecosystem within an Educational Forest; and 3) assessing the feasibility of an Educational Forest as a natural ecotourism destination. The findings of this study are expected to contribute to the development of the educational forest to be managed as a natural ecotourism destination. This research employs field observation and document analysis methods. Field observations were conducted within a sampling area of 2,500 m2 in each plot to collect data on the potency of the educational forest. This included assessing the types, thickness, and density of vegetation, as well as identifying the types of fauna present. Additionally, the components that contribute to the area's appeal, as well as the accessibility and accommodation options, were evaluated across five plots in the forest area. The potential data obtained were used to analyze the level of suitability and feasibility of this educational forest area as a natural ecotourism site. The document analysis included a review of various relevant literature to this research. The results of the study showed that the potential of the educational forest in the KPH Unit XIII includes the biotic potential comprising forest stand types such as Matoa trees, white Meranti (Shorea), banyan, Bugis wood, ironwood, galip nut, Calophyllum, and agarwood. In addition, the forest is home to a diverse range of fauna, including various species of birds, insects, reptiles, and several types of aquatic biota found in the rivers. Further, the educational forest area also possesses abiotic components including soil, water, sunlight, and a tropical climate. Another potential includes the beautiful natural scenery. Almost all types of vegetation were found in the five plots, with an even vegetation thickness of 50 m in each plot. The results of calculations on stand density showed that the highest density index value was found in plot V, namely 0.0076, with a total of 19 trees consisting of five types of trees. Plot III was in second place with a density index value of 0.0072 with a total of 18 trees consisting of five types of trees. Then followed by plot IV with a total density index value of 0.0064 with a total of 16 trees consisting of four types of trees. The lowest total density index value was found in Plot II at 0.0048 with a total of 12 trees consisting of four tree species. Meanwhile, the results of fauna potential observations found that almost all types of fauna are spread across all plots in the educational forest area. The suitability analysis results for the educational forest ecosystem indicated that the forest was classified as an S3 category or conditionally suitable for nature ecotourism, with an ecosystem suitability index value of 47.7%. The suitability level of this forest ecosystem was quite low due tolimiting factors, such as low stand density (0.1432 ind/m2). The low vegetation density was caused by high levels of illegal logging activity. To enhance vegetation density, a rehabilitation program is needed to replant the vegetation of the same types found in the forest area. The feasibility analysis results of the educational forest ecosystem as a natural ecotourism area showed that the Educational Forest Area had a feasibility level of 75.84% (S2). This suggests that the area is suitable for development as a natural ecotourism destination. This high level of suitability is supported by elements of attractiveness, accessibility, and adequate supporting infrastructures. One of the factors inhibiting the level of feasibility of the Educational Forest is the inadequate availability of accommodation. To support the development of the Educational Forest Environment as a natural ecotourism destination, it is necessary to develop decent accommodation facilities, such as rest areas, public toilets, security posts, hiking and camping facilities as well as information boards.
