Abstract


Japanese cucumber (Cucumis sativus) is one of the high-value crops cultivated by farmers at small farms at Sumedang, West Java. The preferences of the customer to health and organic cucumber encourage the development of an organic cultivation system for this crop. One of the most important components of crop production is fertilizer. In this study, three types of organic fertilizers (1) Bokashi, (2) Vermicompost, and (3) coffee testa that was composted by application of black soldier fly (Hermetia illucens) as a decomposer. The growth parameters (plant height and leaves number), harvest (number and weight of fruits), and productivity efficiency (calculated by mass and energy balance) of application of organic fertilizer compared to the control group (only soil). The cucumber was planted in a polybag filled with 4.5 kg growth medium (3 kg soil and 1.5 kg organic fertilizer for treatment groups and full soil for control). The result showed vermicompost group has the best growth parameter and harvest. On the other hand, the control group had slightly higher production efficiency than other groups, The possible factors that affect the production will be discussed.
