The research objective is the redesign of cutting machines and work chairs based on various kinds of information related to human factors which include designing tools and work facilities that are more effective, safe, comfortable, healthy, and efficient (ENASE). Some of the ergonomic parameters that are used as references include aspects of anthropometry, human physical performance, effectiveness-efficiency, work productivity, and the subjectivity of complaints of body pain as a result of inappropriate positions and workloads. In this study, 1 unit of circular model of shell cutting machine was designed and 1 unit of chair / seat. With anthropometric measurements of employees and through ergonomic calculations using the 5th percentile, the dimensions of the work table (cutting table) were obtained, the size of the table height was 87, 9 cm long table 110 cm and table width 64.3 cm. Then the dimensions of the chair are also obtained as follows: seat base height 32.7 cm Chair base length 70.6 cm Chair base width 32.1 cm chair back height 56.8 cm cm, seat back width 44.5 cm After applying the principles of ergonomics, based on the results of the Nordic Body Map questionnaire, it was found that the application of ergonomic principles to work tools for clam shell workers resulted in a 128% decrease in musculoskeletal complaints.

The material used in this study was aluminum waste that came from the rest of the window cutting. The specimens were made using powder metallurgy method. In this study the variations used were the sintering holding time of 120 minutes, 180 minutes, 240 minutes, composition variations of 80% Al : 17% Sic : 3% Glass, 80% Al : 14% Sic : 6% Glass, 80% Al : 11 % Sic : 9% Glass, 80% Al : 8% Sic : 12% Glass. Some control variables are grain size 100 mesh, mixing 15 minutes, compacting 7 tons and sintering temperature 600oC. The results obtained are the highest hardness value is found in the specimen with a sintering temperature of 600oC with a sintering holding time of 240 minutes at a material composition of 80:17:03 which is 90.33 HRF. The macro structure observations showed that there was a smaller porosity in the specimens with high hardness values. The results of the overall mechanical properties test show that the variation of the sintering resistance time has an effect on the specimen which will give time for the formation of stronger bonds between particles. While the variation in the composition of the material with SiC reinforcement the more the percentage given, the greater the composite hardness.","PeriodicalId":227868,"journal":{"name":"Energy, Materials and Product Design","volume":"35 18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123526207","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}

Indonesia is a country with high energy utilization. Energy sources in Indonesia still come from fossil fuels. Burning fossil fuels, such as oil and gas, can cause the greenhouse effect. Therefore we need an alternative energy (biofuel) that is not harmful to the ecosystem. One example of biofuel is bioethanol. \u0000This study used 2 variations, namely stirring rotation (800, 1000 and 1200 rpm) and fermentation pH (4, 4.5 and 5). So from the two variations, 9 kinds of treatment were obtained with 3 repetitions so that the total sample was 27. The purpose of this study was to determine the effect of stirring rotation (rpm) and pH of fermentation on the final yield of bioethanol production. The production of bioethanol is carried out by a fermentation process for 48 hours, then distilled to obtain bioethanol. \u0000 The results of this study indicate that the variation of fermentation pH is the most dominant factor on the level of bioethanol produced, while for the volume of bioethanol produced the most dominant factor is the stirring rotation. The treatment that produced the highest volume of bioethanol was a stirring rotation of 1000 rpm and a fermentation pH of 4 with an average volume of 1234.3 mL and the highest alcohol content was obtained at a stirring rotation of 1000 Rpm and a fermentation pH of 5 with an average value of 81.3%.","PeriodicalId":227868,"journal":{"name":"Energy, Materials and Product Design","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128450636","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}

This is done because most people in Indonesia still use simple tools with unnatural work postures. Unnatural work postures such as bending, squatting, twisting, exposure to the sun, etc. Unnatural work postures cause musculoskeletal complaints and fatigue which have an impact on decreasing work efficiency. Of course, this causes a decrease in productivity and quality of life for workers. From the results of a review of several studies and literature, satisfactory results were found regarding the application of ergonomics in designing work tools according to worker anthropometric data. Application of anthropometric data for the design or redesign of a work tool based on the flow of 1) determining the body that is important in the design or redesign, 2) determining the user population, 3) calculating the percentile value for each predetermined body dimension, and 4) application to the design of the tool.

Existing workshops become a job for some communities and help improve the economy of the community. It is an important concern considering that it is the mechanics who are the main spears in service. From this, a company needs human resources that are able to work effectively and efficiently. To produce human resources that work effectively and efficiently, proper human resource planning and management is needed to encourage the achievement of the company's vision and mission. In planning and managing time it is necessary to take measurements of working time and update existing resources or the need for a tool to accelerate the pace of productivity in the company. One of them is in the oil shock and seal shock changes, and made TsA-1 (shock absorber tool) to make it easier for mechanics to work and know the comparison of time in completing a job, where the normal time obtained by using ordinary tools in oil shock changes is 39.38 minutes and the normal time obtained using TsA-1 (shock absorber tool) in shock oil change is 33.52 minutes. So the mechanic is faster to do his job using TsA-1 (Tool shock absorber), where the time difference is 5.86 minutes. The standard time obtained using a regular tool is 41.45 minutes and the standard time using TsA-1 (tool shock absorber) is 35.28 minutes.
