“…The following parametres are used in the study. Total dry matter mass of daily waste produced = 0.35 x 348kg = 121.8kg According to Buswell, Carbon content of dry matter in the human waste = 24% Total carbon content in the total human waste produced per day = 0.24 x 121.8 kg =29.23 kg From table above, the% biodegradability of human waste is 60% for volatile solids and 50% for total solids [18] Assuming volatile solids. The mass of biodegradable matter = 0.6 x 29.23 kg = 17.54 kg (this is the carbon that will be converted to Biogas).…”

This paper proposes method for generation of electricity using human waste. The human waste was subjected to anaerobic digestion in the biodigester which was taken to be the septic tank with little modification to enhance biogas production and collection. Biogas produced and collected was subjected to treatment to remove CO 2 and H 2 S which were the major corrosive contaminants principally present in the raw biogas stream in order to prepare it as inlet gas for the gas turbine plant. Both single and combine cycle gas turbines were evaluated based on their capacities and electrical power output from unit volume of biomethane gas. FUTO NNDC Hostel with a capacity of 696 students was taken as case study. From the results, it was realised that a total biogas volume of 35 m 3 was produced daily from the NDDC hostel. This gave a total biomethane volume after treatment of 22.75 m 3 . When this biomethane volume was used for electricity generation, it produced an electrical power of 5.21 KW per day for combine cycle gas turbine and 3.22 KW per day for single cycle gas turbine. The results on power usage reveals that the power generated from the NDDC hostel per day will serve the electrical energy needs of 626 households using a daily electrical energy of 0.2kwh if CCGT was used for power generation, and a total of 387 households using the same energy needs of 0.2kWh if single cycle gas turbine were used for power generation.

“…On a design experiment scale, Nisa (2015) has researched the addition of bran for the production of biogas in the wastewater treatment plant. (Andriani et al, 2015) showed that the application of biogas using human excreta provided alternative energy source and helped the environment while sludge itself could be piped to the fish pond or further processed into fertilizer. The investment of private sector in wastewater management is also recommended.…”

Domestic Wastewater Treatment Plant (DWWTP) type 1 and DWWTP type 2 were being evaluated. DWWTP type 1 is located in Sembir area while DWWTP type 2 is located in Tambakrejo area which are both in Sleman Regency, Special Region of Yogyakarta (Daerah Istimewa Yogyakarta or DIY), Indonesia. The emphasis of this research is to choose the manhole material which has the least leakage to the soil, influent discharge performance and wastewater treatment quality effluent. The method used to measure the discharge was by averaging daily discharge for twelve hours, while the E. Coli bacteria under the manhole was also being analyzed. Pollution Index method was also used to evaluate the pollution levels of the wastewater treatment effluent. Results of the study indicated that DWWTP type 1 performance was not optimal because the number of users was greater than that of the design. The impacts were excessive capacity, improper detention time and several parameters of the effluent did not meet the Indonesian legal regulation, including Chemical Oxygen Demand (COD), with efficiency of 34.43%. Wastewater treatment quality effluent parameters which met the Indonesian legal regulation were pH, TSS, TDS, Oil and Grease and Chlorine for DWWTP type 1. Pollution Index (PI) of DWWTP type 1 was 7.02 and PI of DWWTP type 2 was 6.96 which were relatively categorized as moderately polluted. DWWTP type 2 performance was optimal with mean discharge lower than the design discharge. Parameters of the effluent which met the Indonesian legal regulation were pH, TSS, TDS, Oil and Grease, Detergent and COD for DWWTP type 2. The COD of DWWTP type 2 met the Indonesian legal regulation with high efficiency of 73.24%. The E. Coli bacteria was not found in soils under the ring type precast concrete manholes. Hence ring type precast concrete base manhole is recommended.

“…Ini berarti bahwa jumlah nitrogen lebih besar dari pada jumlah karbon, yang mengakibatkan banyak pembentukan amonia dari proses dekomposisi dan selanjutnya meningkatkan pH sistem menjadi basa. Untuk mengatasi kekurangan ini, penambahan bahan baku C/N ratio tinggi sangat dibutuhkan seperti jerami padi (rasio C/N 12,5-25), sekam padi (rasio C/N 100-125), atau tongkol jagung (rasio C/N 50) [7].…”

Abstract– Utilization of human waste as a source of energy can produce methane gas through anaerobic digestion process, where the resulting methane gas is converted into electrical energy. In this research both electrical energy capacity and economics feasibility of Biogas Power Plant development from the utilization of human waste in Pontianak City calculated.Based on the calculation and analysis of electrical energy capacity and economics feasibility, the potential of human waste in Pontianak City produces biogas of 3,091.94 m3/day, methane gas 2,164,36 m3/day, and electrical energy 24,157,88 kWh/day. The result of technical and economic analysis of energy conversion implementation using 250 kW microturbin produces electric power equal to 2,058,254,5 kW per year, pay back period 4 years 11 months, net present value 22,379.004.648 IDR, and internal rate of return of 18,681%, so the construction of Biogas Power Plant is feasible to be implemented. Keywords- anaerobic digestion, biogas, microturbine
