Abstract

The traditional market has degradable waste, especially from the types of vegetables and left over food, the waste is not managed properly will potentially cause disease and poor aesthetics. There are various kinds of recycling and waste utilization efforts to reduce the potential negative impacts and produce a product that is more economically valuable so that the volume of waste does not continue to increase. Based on this consideration, it is necessary to study the generation and composition of waste as well as the potential for biogas from waste in Pasar Pagi Samarinda. The organic material of Pasar Pagi waste which is used as energy through the anaerobic digestion process can be considered from the quality of the biogas and the volume of biogas produced. The determination of waste generation and volume of waste is calculated based on the number of traders in the Pasar Pagi. The biogas production in the digester uses organic waste raw materials from Pasar Pagi and rumen liquid in a ratio of 1:1. The Calculation of gas formed was carried out using a U manometer, temperature measurements using a thermometer, pH measurements using a pH meter were carried out every day and VS measurements were carried out every seven days. The mass of Pasar Pagi waste was 1.81 kg/trader/day and for the volume unit is 4.90 L/trader/day. The total composition of organic waste for vegetables, fruit, and food waste was 85.5%, organic waste in the form of cardboard or paper waste was 2.9%, the composition of plastic waste was 10.7% and metal was 0.9%. The pH of the digester during the formation of biogas shows an acidic condition, and the increase in pH that occurs is only able to reach pH 6 or close to neutral. The temperature in the digester at the beginning of the process tends to increase, then decreases and increases again at the end of the process, but does not affect the biogas production that is still ongoing. The addition of cow rumen contents was able to increase the volume of biogas formed in organic matter and the VS value decreased every week accompanied by the increase in biogas production. This shows that the organic waste in Pasar Pagi has the potential for biogas production.

Abstract

Biogas is one of the renewable energy sources produced from the process of methanogenesis. This research was conducted to determine the optimal composition of palm oil liquid waste (POME) and cow rumen fluid to produce biogas and to determine the effect of the composition of the mixture on the volatile solid value, pH, temperature, biogas production, and flame testing. This study used 3 trial batch type digesters with a capacity of 40 L and the raw material was a mixture of palm oil mill effluent (POME) and cow rumen fluid with a composition of 3 : 1 (R1), 1 : 1 (R2) and 4 : 1 ( R3). During the treatment, pH, temperature, VS and biogas were tested. This research was conducted for 49 days. The research was conducted for 49 days and it was found that the composition of the mixture of palm oil mill effluent (POME) with cow rumen fluid which was optimal for producing biogas was found in R1 with a mixture composition of POME: cow rumen fluid as 3:1. R1 produces a volume of biogas of 1.86 L, from the flame test it can ignite from the third to the seventh week. The composition of the different mixed ingredients for each digester has an influence on the value of VS, pH, temperature, biogas production, and flame tests. The effect was on the difference in VS values, pH, biogas production, and flame test results for each digester, but for the temperature parameter the effect was not too visible because the temperature ranges for the three digesters were both in the mesophilic temperature range, ranging from 27°C - 32°C.
