Pengaruh Biosaka dan Pupuk Kandang terhadap Pertumbuhan dan Produksi Cabai Rawit (Capsicum frutescens L.) serta Pemanfaatannya Sebagai Leaflet

Abstract

Bird's eye chili (Capsicum frutescens L.) is an important horticultural commodity with high economic value; however, the excessive use of inorganic fertilizers may reduce soil fertility and negatively impact the environment. This study aimed to determine the effects of Biosaka and cattle manure application on the growth and yield of bird's eye chili, analyze the interaction between both treatments, identify the optimal treatment combination, and develop a leaflet as an information medium based on the research findings. The study was conducted at the Agrotechnopark Greenhouse, University of Jember, from August to December 2025 using a factorial Completely Randomized Design (CRD) with two factors: Biosaka concentration (0, 3, 6, and 9 mL/L) and cattle manure dosage (0, 150, 250, and 350 g/polybag), each replicated three times. Observed parameters included plant height, stem diameter, number of leaves, fresh weight, dry weight, number of flowers, fruit weight, growth rate, and harvest index. Data were analyzed using Analysis of Variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that Biosaka and cattle manure significantly affected the growth and yield of bird's eye chili and exhibited a significant interaction effect. The combination of 6 mL/L Biosaka and 250 g/polybag cattle manure (B2K2) produced the best performance in most observed parameters, resulting in a plant height of 65,91 cm and the highest fruit weight of 50,68 g. The research findings were subsequently utilized to develop a leaflet, which achieved an average validation score of 81.03% and was categorized as feasible for use. Therefore, the leaflet can serve as an effective information medium for the public regarding the cultivation of bird's eye chili using Biosaka and cattle manure.
