Abstract

The price of chemical fertilizers is currently increasing and increasingly unaffordable for farmers, and their availability is increasingly scarce. Farmers really need fertilizer so that their plants can produce optimally, as an alternative substitution is organic fertilizer using eco-enzyme. Eco-enzyme liquid is the result of fermentation of a mixture of sugar (molasses), organic materials (fruit and vegetable waste), and water with a ratio of 1:3:10 for three months, in an airtight container. The target of this community service is farmers in Pelabuhan Dalam village, and Agricultural Extension Workers (AEW) in Pemulutan District, Ogan Ilir Regency. The purpose of this activity is to provide farmers and AEW with the ability to make eco-enzymes, improve farmers' ability to provide and obtain alternative fertilizers to substitute chemical fertilizers, and provide farmers with skills in applying eco-enzymes as fertilizers. The methods used are socialization with socialization, counseling, eco-enzyme making practices, eco-enzyme applications and mentoring. The results of the community service program have provided farmers and agricultural extension workers (PPL) with the knowledge and skills regarding eco-enzymes and their applications in agriculture. Following this program, 100% of the target audience is capable of making their own eco-enzymes and applying them directly as fertilizer. Furthermore, approximately 40% of the participants have independently produced eco-enzymes, while 60% prefer purchasing the finished product over making it themselves.

Abstract

This study aimed to evaluate the effect of planting media composition in an adaptive floating raft system on the growth of pakcoy (Brassica rapa L.) cultivated in lebak swamp areas. Floating raft systems are expected to address challenges associated with high water-level fluctuations commonly found in lowland swamps while maintaining planting media stability. Three growing media compositions consisting of ultisol soil, manure, and husk charcoal with three different ratios: M1 (2:1:1), M2 (1:1:2), and M3 (1:1:1). Observed parameters included media pH, temperature, moisture content, and pakcoy growth characteristics, namely plant height, number of leaves, leaf width, and fresh and dry biomass. The results indicated that the M3 growing medium provided the most favorable conditions for pakcoy growth, as reflected by superior vegetative growth and biomass accumulation. In addition, the M3 treatment exhibited more stable moisture and temperature conditions, supporting optimal water availability for plant development. Crop water requirements were estimated using the Modified Penman method, showing an increasing trend in water demand along the growth stages. Overall, the adaptive floating raft system combined with an appropriate planting media composition proved effective in supporting stable pakcoy growth under fluctuating water-level conditions in lebak swamp environments.
