Abstract

The study explores the application of bioethical aspects in the use of botanical pesticides for pest prevention in the environment at the Horticultural Seed Development Unit (UPT) under the Department of Agriculture and Fisheries. Utilizing a qualitative approach with quantitative elements, this research aims to deepen understanding regarding bioethical practices in botanical pesticide usage and evaluate its effectiveness in controlling pests. The population consists of employees and students involved in pesticide-related activities, selected through purposive sampling to ensure knowledgeable respondents. Key variables include the independent variable of botanical pesticide application and dependent variables such as pest population reduction, environmental impact, and the presence of beneficial non-target organisms like pollinators. The descriptive qualitative method combined with survey techniques provides insights into how bioethical principles are integrated into pest control strategies, promoting sustainable agricultural practices. This research contributes to advancing environmentally friendly pest management solutions while maintaining ecological balance.

Abstract

This study aimed to evaluate the effect of solid organic fertilizer made from dry leaves, cow manure, EM4, and molasses on the growth of pakcoy (Brassica rapa L.). The experiment was conducted using a Completely Randomized Design (CRD) with four treatments: control (no fertilizer), and fertilizer applications at concentrations of 15%, 30%, and 35%, each replicated three times. Observed parameters included plant height, number of leaves, and fresh weight. Data were analyzed using ANOVA followed by the Least Significant Difference (LSD) test at a 5% significance level. The results showed that the application of solid organic fertilizer significantly affected the growth of pakcoy. The 30% concentration yielded the best results, with an average plant height of 18.3 cm, 10 leaves per plant, and a fresh weight of 22.5 grams. Statistical analysis confirmed significant differences among treatments (p < 0.05). These findings indicate that applying 30% solid organic fertilizer effectively enhances pakcoy growth and supports sustainable organic farming practices.
