Abstract

Compost is one of organic fertilizers that play an important role in maintaining soil health and supporting sustainable agriculture. Diverse aspects could be developed to increase the quality of compost. This study aims to compare the quality of compost produced by using two different bioactivators, namely aerobic bioactivator RMC (the microbial consortia isolated from composted rice straw, mahogany bark and cassava peels + additional supplement) and fermentative bioactivator (EM4 + molasses) in the composting of the mainly rice straw-based materials. Composting was conducted using a single factor completely randomized design consisting of five levels as follows: C0 (control, rice straw); C1 (rice straw + bioactivator EM4 + molasses); C2 (rice straw + bioactivator RMC + additional supplement); C3 (rice straw + cow dung + bioactivator RMC + additional supplement); C4 (leaf litter + cow dung + bioactivator RMC + additional supplement, as comparison treatment with no rice straw). Among the treatments of C0, C1 and C2, composting the same rice straw material but different bioactivators, C2 showed the highest compost quality and decomposition rate. Among the other three treatments of C2, C3 and C4 composting different materials but using the same bioactivator, C3 showed the highest compost quality, but the three treatments showed the same high decomposition rate. Based on the characteristics of the compost product, including nutrient content, the treatment C3 produced the highest quality, followed by C4 and then C2. Both bioactivators EM4 + molasses and RMC+ additional supplement tended to increase total bacteria, fungi, nitrogen-fixing bacteria and phosphate-solubilizing microbiota in the compost products compared to the control without bioactivator. A set of aerobic bioactivator RMC plus additional supplement serve as one strategy to accelerate the composting process and to enhance the compost quality.

Abstract

Pandemi Covid-19 mempunyai pengaruh terhadap ekonomi warga masyarakat, terutama bagi warga yang hanya bergantung pada penghasilan harian. Salah satu cara untuk meringankan beban ekomoni warga akibat dampak pandemi Covid-19 adalah memberdayakan masyarakat untuk menerapkan konsep kawasan rumah pangan lestari agar mengoptimalkan lahan pekarangan. Kegiatan ini mengenalkan budidaya tanaman sayuran dan ikan dengan vertikultur dan akuaponik budikdamer (budidaya ikan dalam ember). Tujuannya adalah untuk membantu mewujudkan kemandirian pangan dan gizi keluarga serta meningkatkan kesejahteraan masyarakat karena adanya peluang bisnis dari kegiatan budidaya tanaman sayuran dan ikan di pekarangan. Kegiatan pengabdian ini dilaksanakan dalam beberapa tahapan, yaitu sosialisasi/penyuluhan, pelatihan dengan pendampingan perakitan instalasi vertikultur dan akuaponik budikdamer serta pendampingan pemeliharaan tanaman dan ikan. Kegiatan pengabdian ini mendapat respon yang positif dan antusiasme dari warga masyarakat. Masyarakat telah merasakan manfaat dari kegiatan ini baik dari segi ekonomi mapun estetika. Kata kunci: akuaponik; budidaya ikan dalam ember; lahan terbatas; sayuran; vertikultur
