Abstract

Kelingi River condition that polluted due to community activities, will certainly disrupt the balance of ecosystems and biodiversity in the River. Especially the Chlorophyta microalgae, which can be used as bioindicator. This study aims to analyze the diversity of Chlorophyta microalgae in Sungai Kelingi Kota Lubuklinggau. This study uses direct survey method, the station consists of 4 stations and each station consists of 3 points. Determination of stations based on different ecosystem characteristics in Sungai Kelingi Kota Lubuklinggau. Based on the results of the research, the type of chlorophyta microalgae found in Kelingi River Lubuklinggau City, consists of: 3 Class 8 Order 12 Family 14 Genus 15 Species. The diversity of stations 1 (1.63), station 2 (1.16), station 3 (2.12) and station 4 (2.10). The dominance of station 1 (32), station 2 (90), station 3 (46) and station 4 (166). Uniformity of station 1 (0.60), station 2 (0.40), station 3 (0.78) and station 4 (0.77). Abiotic factors The River Kelingi consists of: temperature (25.10C), acidity (7.29), dissolved oxygen (43.63mg/ L) and brightness (72.47 cm). Chlorophyta is one of the microalgae divisions that are commonly encountered in the Kelingi River, the unstable growth of Chlorophyta will cause disturbed water conditions. Based on these results, it can be concluded that the diversity of Chlorophyta in Kelingi River Lubuklinggau City is included in the criteria of medium diversity.

Abstract

This community service program aims to provide training to the Karang Jaya Village community on making raised beds using used goods with the Hugelkultur method, in order to improve environmentally friendly and sustainable farming skills. The training was carried out through a participatory approach, where the community was directly involved in every stage of the activity. The program began with a theoretical explanation of the Hugelkultur technique, followed by a demonstration of making raised beds using used goods found around the residents' homes, then conducting direct practice of making raised beds with the Hugelkultur Technique in the field to deepen their understanding. This program succeeded in increasing participants' understanding of the concept of sustainable agriculture and waste management into useful materials for agriculture. The participants showed high enthusiasm and were able to make raised beds with the Hugelkultur technique independently, and were able to utilize used goods around their environment to optimize agricultural yields. This community service program succeeded in providing significant benefits to the Karang Jaya Village community in developing environmentally friendly farming skills. The Hugelkultur method taught can improve the sustainability of household agriculture with more efficient and environmentally friendly costs.
