In developing countries, such as Indonesia, biogas as one of the potential renewable energy sources has positively responded by Indonesian society. However, despite the high biogas demand, biogas consumption pattern in Indonesia is rarely reported in the literature. The biogas consumption pattern is an essential aspect, which can be used as a parameter to improve biodigester performance. This study aims to close the knowledge gap of biogas consumption pattern by studying biogas usage variation in the community biogas plant in Sumedang, Indonesia, as a case study. This study used a literature review and questionnaire as its methodological approach, involving 60 respondents of biogas users. The results showed that the biogas equivalent amount to LPG consumption was 0.669 m3 per household per day or 0.17 m3 per person per day. Meanwhile, the net biogas consumption was 1.92 m3 per household per day or 0.49 m3 per person per day, higher than the reported values in the literature. The inefficiency of biogas stove (34.92% efficiency) was suspected to be the cause of high daily biogas consumption rate. It was also found that 82% (49) of biogas users used biogas in the range of 1 – 2 hours per day. The weekly biogas consumption pattern was found to be constant. Meanwhile, on a daily usage, a variation was found where the daily peak usage time occurred in the morning. Furthermore, this study also addresses the importance of having an efficient biogas stove for optimal biogas utilization.","PeriodicalId":232017,"journal":{"name":"2019 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121177115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The geometry of PTSC must be carefully designed to obtain the optimum performance of the system. Aperture width (w) and focal distance (f) selection are important to determine suitable PTSC geometry, such as rim angle (θr) and concentration ratio (C). This paper presents the influence of aperture width (w) and focal distance (f) to the geometry of PTSC. The analysis is divided into four discussions, namely a variation of w with constant f, a variation of f with constant w, a variation of w and f with constant w/f, and a variation of w and f with different w/f. An analysis was started by determining aperture width (w) and focal distance to obtain rim angle (θr). An analysis was continued by determining the absorber diameter (0.04 m) to obtain the concentration ratio (C). The analysis result shows that θr and C increase with various w (higher) and constant f. Conversely, θr decreases with various f (higher) and constant w, while C determines a constant result. Constant w/f determines a constant θr. A different w/f (lower) decreases θr, while higher w/f increases θr.","PeriodicalId":232017,"journal":{"name":"2019 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115516694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the main objective of this study is to evaluate the flow characteristics of the in-cylinder small engine to see the effect of the intake port configuration at equivalent rated engine speed using simulation model under various intake valve lift conditions. Geometry engine created using CAD software, then exported and analyzed using CONVERGE. The turbulence model is observed using a modified model (RNG) k-ɛ. The pressure boundary conditions are used to determine the pressure fluid at the intake and exhaust port. The result shows that the change combination of the intake port give effect to swirl ratio value. The helical intake port with same direction have the highest swirl ratio during intake and compression stroke around thirteen times compare to the original model in valve lift maximum. The change combination of the intake port also give effect to the tumble ratio where the maximum tumble ratio occurs at the helical port with same direction where the maximum increase at 460 °CA around 83 % and the minimum tumble ratio occurs at helical port with opposite direction where the maximum decrease at 460 °CA around 83 %. The change combination of the intake port also give effect to increase the turbulent kinetic energy where the maximum increase around 300 % for model with same direction and 240 % for model with opposite direction and length scale also increase 35 % for model with same direction and 40 % for model with opposite direction.

The cyclic variation of a diesel engine combustion fueled with CNG and ignited by pilot fuel with different fuel volatility was investigated and presented in this study. To investigate the combustion characteristics of diesel dual fuel engine, a single cylinder diesel engine has been modified to use CNG as fuel. CNG was fed into the intake manifold by a mixer before entering the combustion chamber. The engine was operated at a constant speed of 1400 rpm and variable loads. An engine indicating system was used to sample and record the engine cylinder pressure for 100 consecutive cycles. The combustion data were then analyzed for the maximum cylinder pressure for each cycle and its derivative parameter (rate of heat release). The cyclic variation is indicated by the mean value, standard deviation, and coefficient of variation of the maximum pressure. In higher engine load operation, the cyclic variability is found to be reduced. In addition, volatile pilot fuel resulted in more stable combustion especially at low load.","PeriodicalId":232017,"journal":{"name":"2019 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122307749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
