Koperasi Unit Desa (KUD) adalah lembaga pedesaan yang memiliki peran penting dalam pembangungan pertanian. Namun saat ini kemandirian KUD belum kuat karena KUD masih merupakan kepanjangan tangan pemerintah untuk melaksanakan program pembangunan pedesaan terutama di sektor pertanian. Penelitian bertujuan untuk mendapatkan faktor-faktor kunci manajemen KUD serta menentukan besar pengaruh masing-masing faktor tersebut terhadap kemandirian KUD. Penelitian dilakukan terhadap 10 KUD Kabupaten Garut yang berhasil mengembangkan KUD di tingkat nasional melalui survai lapangan dengan bantuan kuesioner untuk mendapatkan data primer. Data yang terkumpul dianalisis dengan menggunakan Structural Equation Modelling (SEM) untuk menentukan besarnya pengaruh faktor kunci berupa faktor laten endogen dan eksogen terhadap keberhasilan dalam manajemen KUD. Analisis variabel-variabel yang diteliti menghasilkan l5 faktor kunci laten endogenous dan 80 faktor kunci latent exogenous. Seluruh faktor kunci tersebut direkomendasikan untuk digunakan sebagai pedoman dalam upaya pemberdayaan KUD ke arah kemandirian.

The addition of organic matter in marginal soils is important to do in an effort to increase soil fertility so that plants can grow and produce optimal production. The purpose of this study was to obtain a dose of decomposer and length of incubation time in bokashi swallow droppings capable of increasing the growth and yield of green mustard plants (Brassica juncea L.) in marginal soils. This research was conducted at a screenhouse located in Sentiong Village, Rawagempol Wetan Village, Cilamaya Wetan Subdistrict, Karawang Regency, West Java. The method used was an experimental method with a factorial Randomized Block Design (RBD) consisting of two factors. The first factor is the decoposer dose consisting of 2 levels, namely: D1 (0 ml) and D2 (10 ml). The second factor is the length of incubation time consisting of 5 factors: W1 (0 days), W2 (4 days), W3 (8 days), W4 (12 days), and W5 (16 days). The results showed that there was no noticeable influence on the use of decoposer doses and differences in incubation time in bokashi swallow droppings against plant height parameters, number of leaves, fresh weight of plants, and dry weight of plants. However, there is an interaction influence on the parameters of the greenish level of the leaves. Giving of decomposer 10 ml (D2) treatment with an incubation time of 12 days (W4) was the best combination of treatment because it is able to provide the highest values on the height parameters of the plant (D2: 3,83-26,44 cm) and (W4: 3,88-26,67 cm), the number of leaves (D2: 3,87-11,00 leaf strands) and (W4: 3,89-11,11 leaf strands), and fresh weight of the plant (D2: 93,60 grams) and (W4: 102,18 grams).

The continuous use of inorganic fertilizers without the application of organic fertilizers can cause nutrient imbalances in the soil, low fertilization efficiency, damage to soil structure, and low soil microbiology. This experiment was conducted in Experimental Station of Indonesia Center for Rice Research Sukamandi Jaya Village, Subang District, West Java from July to November 2020. The objective of the experiment was to find out of N, P, K and organic fertilizer that gave the best yield on growth and yield of rice (Oryza sativa L.). The research was used experimenthal method it was arranged in split plot design with 6 threatment and 4 replications. As the main plot was N, P, K fertilizer, consist of 4 threatment of fertilizer: P1 (kontrol), P2 (+PK), P3 (PHSL), P4 (NP), P5 (+NK), and P6 (+NPK). As subplot was organic fertilizer: B1 (2 ton/ha), B2 (compost rice straw 5 ton/ha), and B3 (control). The effect of treatment is analyzed with variety analysis and if the F test is 5% significant, then to find out the best treatment continued with further DMRT tests (Duncan Multiple Range Test). The results showed that there was an interaction between the provision of inorganic and organic fertilizers to the height of plants aged 35 days after planting and 1000 grains weight. Meanwhile, at the height parameters of plants aged 21 days after planting, 57 days after planting, 64 days after planting, and 84 days after planting, number of tillers, number of panicles per hill, number of grains, and the grain yield there are real influences independently. The highest grain yield of 4,84 Kg/tile (6,45 tons/ha) was achieved by P5 (+NK) treatment and was not real different from P3 (PHSL), P4 (+NP), and P6 (+NPK) treatment with consecutive weights of 4,82 Kg/tile (6,43 tons/ha), 4,44 Kg/tile (5,92 tons/ha), and 4,46 Kg/tile (5,95 tons/ha).
