Abstract

This study evaluated the effect of bokashi from slaughterhouse waste and NPK compound fertilizer on the growth and yield of purple eggplant (Solanum melongena L.). The experiment was conducted in Sambaliung, Berau, for 4 months with a factorial Completely Randomized Design (CRD). Bokashi was given in five doses: B0 (control), B1 (5 MgHa-1), B2 (10 MgHa-1), B3 (15 MgHa-1), and B4 (20 MgHa-1). NPK fertilizer was applied in four doses: P0 (control), P1 (5 gr/polybag), P2 (10 gr/polybag), P3 (15 gr/polybag), and P4 (20 gr/polybag). The parameters observed included plant height, flowering age, and fruit weight per plant. Data were analyzed using ANOVA and Duncan's test at the 5% level. The results showed that the combination of bokashi and NPK had a significant effect on plant height, but not significant on flowering age and fruit weight. The use of bokashi and NPK effectively increases the growth of purple eggplant, so it can be an alternative for farmers to reduce dependence on NPK chemical fertilizers and switch to organic methods sustainably

Abstract

The intensive use of synthetic chemical pesticides in agriculture has led to various negative impacts on the environment and human health, as well as increased pest resistance. As an alternative, plant-based pesticides (botanical insecticides) have shown potential due to their eco-friendly and sustainable nature. This study aims to review the effectiveness of soursop (Annona muricata) leaf extract as a botanical pesticide against the gray caterpillar (Spodoptera litura) on mustard plants (Brassica juncea), using a literature review method. Data were collected through a systematic search of accredited national and international scientific journals, then analyzed descriptively and comparatively. The findings indicate that soursop leaves contain bioactive compounds such as acetogenins, flavonoids, and saponins, which act as stomach poisons, antifeedants, and repellents to S. litura. Several studies reported that extracts from Annona spp. leaves and seeds effectively inhibit larval growth, reduce feeding activity, damage digestive tissues, and lead to larval death. This effectiveness highlights the potential of soursop leaves as a safe and efficient candidate for botanical pesticide development. The study also identifies a research gap regarding field-scale testing on mustard plants, suggesting the need for further agronomic validation.
