Abstract

This Community Service Program aims to implement an aquaponics system with DFT hydroponics in water spinach cultivation in Dolok Sagala Village, Dolok Masihul Subdistrict, Serdang Bedagai Regency. The aquaponics system combines fish farming with plant cultivation, where fish wastewater is used as a plant nutrient source. In contrast, the DFT hydroponics system allows efficient nutrient circulation. The application of this technology aims to increase agricultural productivity in limited land areas, provide sustainable farming solutions, and enhance local food security. The results of this activity show that the aquaponics and DFT hydroponic systems can significantly improve the growth of water spinach with minimal use of land and resources. Community participation in this activity also increased, reinforcing awareness of the importance of modern agricultural technology.

Abstract

Tujuan dari penelitian ini adalah : 1). Mengetahui perbandingan campuran tandan kosong kelapa sawit (TKS): Limbah Cair PKS (LCPKS) dan EM4 yang tepat dan dapat mempercepat dekomposisi TKS dalam pembuatan kompos, 2). Mengetahui kandungan N,P,K, dan C/N yang dihasilkan dari selama fermentasi pada pembuatan kompos. Penelitian dilaksanakan dengan RAL non factorial dengan factor tunggal campuran TKS: LCPKS dan EM4.Setiap kombinasi perlakuan diulang sebanyak 3 kali. Data diolah dengan menggunakan statistik dengan uji Analysis of variance (ANOVA) dengan uji lanjut DMRT pada taraf 5%. Hasil penelitian ini menunjukkan bahwa kadar Nitrogen (N), Fosfor (P), Kalium (K), rasio C/N dan kadar air berpengaruh tidak nyata dan belum sesuai dengan SNI Perlakuan yang terbaik terdapat pada C3.

Abstract

Acceleration of processing for fresh fruit bunches (FFB) is crucial to increase profitability and business opportunities for oil palm farmers. This research aims to evaluate the effect of using gamal (Gliricidia sepium) leaves and the duration of ripening on the percentage of FFB processing as well as the quality of crude palm oil. This study employed a factorial completely randomized design (CRD). The data were analyzed using ANOVA with Duncan’s Multiple Range Test at a significance level of 5%. The results of the analysis showed that the best treatment was S3T2 (40% gamal leaves, 20 h of ripening) with a natural processing percentage of 45.87% of the FFB weight and 60.34% of the total bunch weight. The use of gamal leaves and the duration of ripening significantly affected the quality parameters of the oil, especially the free fatty acid content. Treatment S1T1 (20% gamal leaves, 10 h of ripening) showed the best results with a free fatty acid value of 1.30%, meeting the quality standard (<5%). However, the moisture content still exceeded the quality standard (<0.5%), although treatment S3T2 yielded the best result at 0.63%. While, the impurity content quality met the quality standard (<0.5%), with the best value achieved by treatment S1T1 at 0.15%. Keywords: Bunch detachment, CPO quality, Ethylene, Gliricidia sepium, Ripening.
