This machine can be used to assist partners in the process of embalming Salak to produce good quality and guaranteed freshness. The steps in the manufacture of this machine start from the design, the provision of tools and materials, manufacture and test the machine. The results show that the machine works optimally with the average production of salak 25 kg/hour due to embalming. In addition, the embalming machine has a propulsion engine that serves as the embalming and drying of Salak.","PeriodicalId":232378,"journal":{"name":"Jurnal Geliga Sains: Jurnal Pendidikan Fisika","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116011714","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 type of research used was experimental research.Descriptive analysis was used to analyze the data. This analysis gave the description about influence ofGuided Discovery Learning model toward student's critical thinking ability. The subjects of this study were58 students. The data was collected based on critical thinking skill's test result which consisted of 15 essayquestions for 5 indicators after Guided Discovery Learning model was applied on experiment class andconventional model on control class. Mean score of sudents' critical thinking ability on experiment class was78.45 which was in a high category and average score of students' critical thinking skill on control class was70.52 which was in low category. Based on the result of students' critical thinking skill, it can be concludedthat there was an improvement of critical thinking ability after guided discovery learning model was appliedby 11.24% compared to conventional learning model.","PeriodicalId":232378,"journal":{"name":"Jurnal Geliga Sains: Jurnal Pendidikan Fisika","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116581205","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}
