Abstract

Abstract. Slaughterhouses (RPH) produce large amounts of solid waste every day and have not been utilized optimally. RPH solid waste has great potential to be used as plant fertilizer through the composting process. Composting is expected to change the organic material composition of the abattoir solid waste to be more ideal to support plant growth. This study aims to determine the chemical composition of compost made from waste at RPH Tamangapa Makassar City before and after the composting process. Composting from solid waste at Tamangapa RPH Makassar was carried out using the main ingredients, namely rumen contents (treatment I) and rumen contents mixed with livestock manure in a ratio of 1:1 (Treatment II). The composting process was carried out in a compost box with a size of 40x40x60 cm with a passive aeration system for 4 weeks with three replications. Quantitative data tested in this study included the content of N-total (%), C-Organic (%), P-total (%), K-total (%), C/N ratio, organic matter (%), water content (%) and compost reduction (%). The results showed that the content of elements C, N, P, K, C/N ratio, organic matter, and water content before composting in both treatment I and treatment II were generally still low and almost the same as the raw materials. After the composting process took place, the content of C, P, K, C/N ratios generally showed an increase, while the N content was relatively constant. The results of the analysis showed that there was no significant difference between the chemical composition of the compost in the treatment and both before and after the composting process.Keywords: RPH solid waste, composting process, chemical composition of compost, C/N ratio.

Abstract

Abstract. Slaughterhouse waste is generally disposed into the environment without being processed, so that it potentially causes air pollution, water pollution, and soil pollution. Slaughterhouse waste can be processed and used as plant fertilizer through the composting process. This study aims to compare the composting performance of solid waste at Tamangapa RPH Makassar between the main ingredient consisting of rumen contents only (treatment I) with that consisting of a mixture of rumen contents with livestock manure (treatment II). We recorded quantitative data including temperature (0C), pH, material mass reduction and composting time and qualitative parameters including color, smell and texture of the resulting compost. The composting process was carried out in a compost box with a size of 40x40x60 cm with a passive aeration system for 4 weeks with three replications. Our results demonstrated that treatment I and treatment II had a similar pattern of temperature changes, while the average pH of treatment I was higher compared to treatment II. Based on the composting performance data including changes in temperature and pH from the first week to the fourth week of composting, we concluded that both treatments resulted in a rapid composting process with good-quality compost.Keywords: composting performance, RPH solid waste, composting process, rumen contents, passive aeration.
