Abstract. Sondapa S, Lestari T, Pratama D. 2023. Utilization of waste baglog and NPK fertilizer for cayenne pepper (Capsicum frutescens) cultivation in post-tin mining tailing media. Pros Sem Nas Masy Biodiv Indon 9: 29-36. Cayenne pepper (Capsicum frutescens L.) is one of the horticultural plants of the vegetable type, which contains capsaicin with a spicy taste. Cayenne pepper plants are easily cultivated in various places in the rainy and dry seasons. Generally, the planting medium for cayenne pepper is often used is topsoil, with the addition of organic matter as composting. Using waste baglog as oyster mushroom (Pleurotus ostreatus) growing media is an alternative to composting material in cayenne pepper cultivation in tailings media. This research aims to utilize waste baglog as an additional organic matter to chili cultivation in tailing media. This research was conducted at the Experimental and Research Station (KP2), the University of Bangka Belitung, from January to August 2022. This study used a non-factorial Randomized Block Design (RBD) consisting of 5 treatment factors with 4 replications. The treatment consisted of K0 = Application of commercial compost (the control), K1 = Application of oyster mushroom waste baglog compost, P0 = Without application of NPK fertilizer (the control), P1 = Dose of NPK fertilizer at 600 kg/ha (29 g/plant), P2 = NPK fertilizer dose at 450 kg/ha (22 g/plant), P3 = NPK fertilizer dose at 300 kg/ha (14.7 g/plant). The cayenne pepper plant reactions on applying different composts are emergence in the vegetative and the generative phases, including plant height, branch numbers, flower emergence, fruit emergence, harvest age, number of fruit/plant, and fruit/plant weight. The number of branches parameter shows the plant's reaction to applying various doses of NPK fertilizer. The combination of compost treatment with NPK fertilizer doses did not significantly affect the growth and production of chili plants in tailings media.
