“…Recently Haryanto et al (2017) reported that a family scale biogas digester with five cows potentially provides annual economic benefit of 111.6 USD and reduce greenhouse gas emission by 2674.8 kg CO2 equivalent. Family size biogas technologies play a significant role to fulfil energy need in some countries such as China (Chen et al, 2014), India (Singh & Sooch, 2004), Nepal (Barnhart, 2014), Bangladesh (Khan et al, 2014), and Vietnam (Nguyen, 2011).…”

The efficiency of biogas production in semi-continuous anaerobic digester is influenced by several factors, among other is loading rate. This research aimed at determining the effect of hydraulic retention time (HRT) on the biogas yield. Experiment was conducted using lab scale self-designed anaerobic digester of 36-L capacity with substrate of a mixture of fresh cow dung and water at a ratio of 1:1. Experiment was run with substrate initial amount of 25 L and five treatment variations of HRT, namely 1.31 gVS/L/d (P1), 2.47 gVS/L/d (P2), 3.82 gVS/L/d (P3), 5.35 gVS/L/d (P4) and 6.67 gVS/L/d (P5). Digester performance including pH, temperature, and biogas yield was measured every day. After stable condition was achieved, biogas composition was analyzed using a gas chromatograph. A 10-day moving average analysis of biogas production was performed to compare biogas yield of each treatment. Results showed that digesters run quite well with average pH of 6.8-7.0 and average daily temperature 28.7-29.1. The best biogas productivity (77.32 L/kg VSremoval) was found in P1 treatment (organic loading rate of 1.31 g/L/d) with biogas yield of 7.23 L/d. With methane content of 57.23% treatment P1 also produce the highest methane yield. Biogas production showed a stable rate after the day of 44. Modified Gompertz kinetic equation is suitable to model daily biogas yield as a function of digestion time.Article History: Received March 24th 2018; Received in revised form June 2nd 2018; Accepted June 16th 2018; Available onlineHow to Cite This Article: Haryanto, A., Triyono, S., and Wicaksono, N.H.

“…This estimated resource potential is used to calculate the biogas potential in the area. Amount of biogas needed for the poly generation unit to provide cooking gas and electricity for certain number of households was calculated using Khan et al, [10] estimation. So in this part only the biogas potential is estimated to see if the available resources would be sufficient to produce enough biogas to meet the combined demand of cooking gas and electricity for the households in the study area.…”

Average electricity demand which is used here is 27 kWh per household per month calculated by Khan et al [10]. For producing 27kWh of electricity for each household per month and the biogas requirement for the whole area is 100 m 3 per day [10].…”

Abstract:Khulna is located in the south western part of Bangladesh. Khulna is the third largest city of Bangladesh where the livelihood depends on mostly agricultural practices and livestock farming. Thus there might have significant potential for biogas production. From this point of view the present study has been taken into consideration. A structured questionnaire survey was conducted to investigate the plenty of livestock resources, their energy consumption pattern, biogas production, and replacement of traditional energy consumption with biogas in 80 households which is selected randomly. Study found that total manure production is 3080125.5 kg/yr and residues production is 102252.34 kg/yr. 94 percent of the households are still using mud stoves as their first priority. Useful cooking energy demand in the case of surveyed area comes out to be 77420 kWh per year. The total biogas demand of the study area to provide cooking gas and electricity is 56981.5 m 3 per year whereas the total potential biogas production is 125838.18 m 3 /yr in the study area. The potential produced biogas will completely fulfill the biogas demand in the study area.

“…The total number of installed biogas digesters in Vietnam accounted for about 200,000 units (Nguyen, 2011). Recently, Bangladesh has installed more than 40,000 domestic biogas plants using cow dung or poultry litter (Khan et al, 2014). Domestic biogas is also growing in Africa thanks to support from Netherlands Development Organization SNV (Stichting Nederlandse Vrijwilligers).…”

The objective of this research was to evaluate economic benefit and greenhouse gas (GHG) emission reduction potential of a family-scale anaerobic cowdung biogas digester. Research was conducted at two villages in Lampung Province, namely Marga Lestari, District of South Lampung and Pesawaran Indah, District of Pesawaran. Economic benefit and GHG emission reduction potential were evaluated from LPG saving due to biogas utilisation for cooking and fertilizer substitution by slurry digestate. Results showed that a family-scale anaerobic cowdung biogas digester demonstrated a good potential to reduce GHG emission, but not in economic. A digester with 4 heads of cow produced biogas at a rate of 1582 L/day. With average methane content of 53.6%, energy value of the biogas was equivalent to 167 kg LPG and able to substitute 52 bottles LPG annually. A family-scale biogas contributed 108.1 USD/year and potentially reduced GHG emission by 5292.5 kg CO2e/year resulted from biomethane potential, LPG, and fertilizer savings.Article History: Received November 15th 2016; Received in revised form January 16th 2017; Accepted February 2nd 2017; Available onlineHow to Cite This Article: Haryanto, A., Cahyani, D., Triyono, S., Murdapa, F., and Haryono, D.
