Bulungan Regency is one of 160 urban regencies in Indonesia that is intervened to focus on reducing stunting. Based on these problems, this study aims to determine the cluster of stunting vulnerabilities in Bulungan Regency. The method used is Fuzzy C-Means (FCM). The results of this study are that the area in cluster 1 has a high level of vulnerability because it has the lowest level of adequacy of posyandu (active) and high incidence of LBW in infants, cluster 2 has a moderate level of vulnerability because it has an adequate level of puskesmas, adequacy of posyandu (active), the adequacy of doctors, the adequacy of nutritionists, the adequacy of midwives, the percentage of moderate LBW, and cluster 3 have a low level of vulnerability because they have a low average percentage of LBW and a high level of adequacy of posyandu (active) in the area.","PeriodicalId":181108,"journal":{"name":"International Journal of Natural Science and Engineering","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127422217","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}

Aim of this study is to find the role of organization maturity level in order to improve the information system (IS) capability through ERP implementation approach. There are four variables involved on this study, namely: ERP drives Business Process Reengineering (BPR) (X1), BPR drives ERP (X2) as independent variables, organization maturity level (Y) as a moderating variable, and IS capability (Y1) as a dependent variable. We applied the path analysis to identify direct and indirect effect between ERP implementation approach and IS capability through organization maturity level. There are 277 key individuals from 37 different organization which is represented 10 industrial sectors responded to the questionnaires. The response rate for this survey research is 39.57% from 700 questionnaires which were distributed. Survey result shows that organization maturity level has a major role which can improve to better IS capability in organization. It is shown that a direct effect between X1 and Y1 (ρY1X1=0.331) is lower than an indirect effect between X1 and Y1 through Y (ρYX1 and ρYY1 = 0.369). Whereas, direct effect between X2 and Y1 (ρY1X2=0.096) is lower than indirect effect between X2 and Y1 through Y (ρYX2 and ρYY1 = 0.233). It can be concluded that the organization has to put a more effort on organization maturity level in order to gain a better IS capability, especially when it uses BPR drives ERP approach to implement the ERP system.","PeriodicalId":181108,"journal":{"name":"International Journal of Natural Science and Engineering","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116268532","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}

Many work accidents occur in chemical laboratories. Two factors that cause work accidents are unsafe behavior and unsafe conditions. Occupational safety and health in the laboratory are crucial to creating a comfortable, safe work environment to prevent or minimize workplace accidents. This study aims to produce a handbook of occupational safety and health in chemical laboratories as a guiding supplement for chemistry practicum to create occupational safety and health in chemical laboratories. This research is a research and development (r&d) with a 4-d development model consisting of 4 main stages: define, design, develop and disseminate. Research is limited to the development stage, which ends with a practicality test. Based on expert judgment, it was found that the occupational safety and health handbook in the chemical laboratory are very valid in terms of content (3.9), language (4.0), and media (4.0), from a maximum score of 4. From the readability test, all respondents obtained students understand the content or information presented in the chemical laboratory's occupational health and safety handbook. Furthermore, through the practicality test, it was obtained that lecturers, laboratory assistants, and students gave an assessment that the occupational safety and health handbook in the chemical laboratory each scored 4.0 and 3.9, which means it is very practical. This research concludes that the chemical laboratory's occupational safety and health guidebook as a guiding supplement for chemistry practicum is valid to be implemented from the aspect of content, language, media, and readability and is very practical in its use.","PeriodicalId":181108,"journal":{"name":"International Journal of Natural Science and Engineering","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128610229","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}

According to the Ministry of Environment and Forestry, the area of forest and land fires is calculated based on an analysis of Landsat 8 OLI/TIRS satellite imagery, which is compared (overlay) with data on the distribution of hotspots. In this research, the Internet of Things (IoT) can be useful in preventing forest fires that usually occur on the slopes of Merbabu during the dry season. IoT sensor technology can detect air humidity, temperature, and wind speed parameters for fires in the dry season. This study aims to warn of potential forest and land fires in Mount Merbabu by providing notifications from IoT sensors. From the sensor testing that has been done, it can be seen that the sensor can provide information accurately and in real-time. The tests were carried out in three places: at the foot of Mount Merbabu, the SWCU FTI Peak, and the rice fields. The different results in three places with different vegetation indices indicate that the design of a fire potential warning system based on the Internet of Things in the dry season (July – September) can be used in areas with a low vegetation index on the slopes of Mount Merbabu, the majority of which are dry and easy grasslands burnt.","PeriodicalId":181108,"journal":{"name":"International Journal of Natural Science and Engineering","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115791435","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}
