The livestock sector's waste is a potential raw material for producing biogas because it is abundantly available. This experiment aimed to understand the potential of two types of livestock waste to produce biogas. The two sources of raw material were mixed with different variations. The results showed that the volume of fermentation gas produced from livestock waste varied depending on the type and composition of the raw material used. Mixing was done to determine the best variation in producing biogas from chicken litter and cow manure. The volume ratio of litter to cow manure used was (0%:100%), (25%:75%), (50%:50%), (75%:25%), (and 100%:0%), with a total volume of 2 liters. In addition, 10% of EM-4 (effective microorganism) was added to the mixture of livestock waste that had previously been given 2 liters of water. The waste mixture was then fermented for 30 days. The fermentation process was carried out under mesophilic conditions at room temperature and pressure. This study showed that the higher the concentration of chicken litter in the mixture, the higher the carbon-to-nitrogen (C/N) ratio value. On the other hand, if there is a higher composition of cow manure in the mixture, the substrate pH value will be higher. Furthermore, a 50%:50% composition of chicken litter and cow manure produced a high volume of biogas. Similarly, the biogas formation rate in this composition showed the best performance. These results prove that the balance of carbon and nitrogen composition, temperature, and substrate acidity significantly affect biogas production.

Awareness to anticipate the future crisis of fossil fuel, particularly oil, has encouraged efforts to find alternative sources of fuel, especially those derived from plants, one of which is bioethanol. Bioethanol is a renewable fuel with high economic value. From various potential plant sources that can be developed into alternative fuel, one of them is sweet sap from sorghum stalk. This research aims to determine the effect of different types of yeast on the volume, alcohol content, and specific gravity of bioethanol produced from sorghum stalk. The variations of yeast used in this research were tapay yeast, baker’s yeast, and turbo yeast, with a yeast mass of 10 g/L, NPK (nitrogen, phosphorus, potassium) mass of 0.6 g/L, and urea mass of 0.5 g/L. Bioethanol was produced from the sweet sap through a 3-day fermentation process, with a sample volume of 3 liters, followed by distillation using a vacuum distillation apparatus. The research was conducted at room temperature and pressure so that all sweet sap obtained the same treatment before being given different types of yeast. The results of the research showed that the highest alcohol content was obtained from the fermentation process using tapay yeast, followed by baker’s yeast and turbo yeast. Meanwhile, the largest volume of bioethanol was obtained from the fermentation process using turbo yeast. The highest specific gravity of 0.9456 was also obtained from the fermentation process using turbo yeast, while the lowest was obtained from the fermentation process using tapay yeast.
