In this study, new source of renewable energy is based in the briquette made from mixture of ironwood (Eusideroxylon zwageri) powder and gelam (Melaleuca leucadendron) wood powder. The mixture was carbonized at temperature of 500 oC ± 10 oC for 120 minutes. The size of the particles used was 50 mesh while the ratio between wood powder adhesives, i.e. starch powder, used in the study was 1:1. The composition variations between ironwood charcoal and gelam were 100% ironwood charcoal powder and 0% gelam, 70%: 30%, 50%: 50%, 30%: 70%, 0% ironwood: 100% gelam. The compaction pressure during briquette production was varied at 100 kg/cm2, 125 kg/cm2 and 150 kg/cm2. The highest combustion temperature at 205 oC occurred in the specimen with composition of 30% ironwood powder and 70% gelam wood powder with compaction pressure of 100 kg/cm2. The longest burning duration 140 minutes (2 hours 20 minutes) occurred at composition of 50% ironwood powder and 50% gelam wood powder at compaction pressure of 150 kg/cm2. The fastest initial ignition time was 7 minutes and occurred for mixture with composition of 70% ironwood powder and 30% gelam wood powder at compaction pressure of 125 kg/cm2.","PeriodicalId":159477,"journal":{"name":"International Journal of Mechanical Engineering Technologies and Applications","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133230981","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}

Patria Donut produce in accordance with the number of orders from distributors and only in accordance with the desire to generate sales for end buyers. The location is difficult to reach by the customer makes this business unpopular. Seeing this fact, the owner wants to expand his business by opening a cafe in a more strategic location, in Jalan Lombok. We should do feasibility analysis by opening this café. The market is conducted by spreading questionnaires to 100 respondents (target 16-39 years) in Bandung. The results showed a potential market of 86%, 98% available market, and the target market the company aimed at 0.8% of the available market. Meanwhile technical aspects and financial aspects based on secondary data from various sources. The financial calculation obtained from the NVP value for 2020-2024 are Rp 229.258.502,00, the IRR percentage is 26,69%, and PBP is 4 years and 4 months. IRR obtained is greater than the MARR value of 9.95% and NVP is positive. From these parameters, the opening of the Doria Cafe on Lombok Street, Bandung was feasible. We used website to support this business design.","PeriodicalId":159477,"journal":{"name":"International Journal of Mechanical Engineering Technologies and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133443679","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 utilization of nanomaterials in the world of education has been done in two universities in Malang, namely Malang State University and Brawijaya University. The nanomaterial laboratory as a means for research and development of nanomaterial science that often creates hazards and risks of work accidents for its users, but things that are often not realized. Dangers and risks of work accidents caused by the absence of standards. This research focuses on hazards and accidents in the nanomaterial laboratory using the HIRA (Hazard Identification and Risk Assessment) method, which is then followed by a variety of independent variables. The population in this study were nanomaterial researchers at two universities in Malang. Based on the results of trials between respondents 'competency expertise with the level of risk of workplace accidents in the nanomaterial laboratory obtained p- value 0.00 (<0.05), meaning that there is a significant relationship between the respondents' scientific conservation and the level of work accident risk in the nanomaterials laboratory. Furthermore, the results of the study were also obtained between the research respondents with the level of risk of work accidents in the nanomaterial laboratory with a p-value of 0.00 (<0.05), meaning that there was a significant correlation between the respondent's research experience and the level of work accident risk in the nanomaterial laboratory.","PeriodicalId":159477,"journal":{"name":"International Journal of Mechanical Engineering Technologies and Applications","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123246756","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}
