There are several types of variant ships, such as military ships, tourist boats, cargo ships and passenger ships. Apart from being a place for shipbuilding, shipyards are utilised to conduct several activities, such as ship design, equipment installation, plate installation, feasibility tests and classifications. There are many production activities and flows that allow for potential waste problems that impact labour usage, product quality, costs, and production time. This research aims to identify waste in shipbuilding production lines through a lean manufacturing approach. The lean manufacturing approach is one of the ways in shipyards to observe the level of waste in the production process to reduce unnecessary activities in the production process, which can increase production efficiency and effectiveness. This study approach begins with identifying waste in the production line through mapping on each line so that activities with no added value are identified. On the basis of the results of identification using the waste assessment model (WAM) method, which consists of a waste relationship matrix (WRM) and a waste assessment questionnaire (WAQ), waste is obtained, namely inventory (27,20%), overproduction (20.24%), defective products (20.04%), motion (12.47%), transportation (9.23%), waiting time (7.46%) and process (3.37%)","PeriodicalId":344452,"journal":{"name":"International Journal of Global Optimization and Its Application","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115291972","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}

It is a common disease that can led to several health complications and mortality. In Malaysia, most of the cases are categorized as Diabetes Mellitus (DM) Type II. Patients with diabetes increases from year to year due to unhealthy lifestyles e.g. smoking, overweight and hypertension. Therefore, this study meant to identify the influential factors that may contribute to DM Type II by comparing the performance of different data mining approaches. Between April 2017 and November 2018, 684 patients from a public clinic participated in this retrospective cross-sectional study. Four predictive models involved in the study are Logistic Regression, Decision Tree, Naïve Bayes, and Artificial Neural Network (ANN). The error measures (Average Squared Error and Misclassification Rate) with ROC Index are used to evaluate the performance of the models. Results show that the performance of Logistic Regression-Stepwise outperformed to other predictive models with classification accurateness of 73% and able to predict positive outcome (Y=1) correctly by 90%. The significant inputs that affect DM Type II prediction (Y=1) are Hypertension and Glycated Hemoglobin (HbA1c) given the Root Mean Squared Error (RMSE) of model is 0.424.

By using panel data regression and data sourced from 32 provinces throughout Indonesia, the results show that poverty has a negative but not significant effect, FDI has a positive and significant effect, and HDI has a positive and significant effect. On the other hand, Domestic Investment has a positive but not significant effect on GRDP. In an effort to increase the value of GRDP, HDI, and investment (FDI and HDI) that can reduce poverty, the government, the private sector, and the community play an active role in cooperating in planning and implementing effective and efficient strategic program activities, including maintaining social security stability and politics, sustainable reform in all sectors by encouraging the use of domestic products, empowering elements of society including Micro, Small and Medium Enterprises, facilitating various vocational skills training for productive workers and drafting investment-friendly licensing governance regulations.

These problems have different solutions depending on the character of the poor population in the country. One of the proposed solutions is to control prices so that the level of public consumption is maintained. The purpose of the study was to analyze the effect of rice prices on poverty and to map the condition of rice price movements related to poverty in provincial capitals in Indonesia. This study uses panel data from 34 provincial capitals in Indonesia from 2011 to 2020. The data was collected from the Central Bureau of Statistics of Indonesia and uses a panel regression model and important performance analysis (IPA). The results of this study indicated that the price of rice positively affects poverty in provincial capitals in Indonesia. The IPA results show that most provincial capitals in Indonesia are in areas with low poverty rates accompanied by low rice prices and areas with poor people but tend to have high rice prices compared to the average price of rice. It concludes that rice greatly influences the consumption needs of the people of provincial capital cities in Indonesia. This finding shows the importance of maintaining the stability of rice prices due to the large influence of rice price movements on the increase in the percentage of poor people. Suggestions should be given for subsidized rice distribution in areas with high prices.","PeriodicalId":344452,"journal":{"name":"International Journal of Global Optimization and Its Application","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132217208","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}

Like any other major industry, O&G is exposed to a host of both predictable and unpredictable risks. Joint venture projects (JVP) are often regarded as risky businesses as there is a high failure rate among them because of the complexities involved. This paper aims to identify the critical risk factors (CRFs) of JVPs for O&G between Malaysia and Thailand. Via systematic literature review (SLR) the risk factors for O&G and JVPs around the globe are identified and a set of questions relating to them designed and used in a pilot study. A total of 15 respondents from different background experiences working in O&G JVPs were requested to answer the designed questionnaire during the pilot study. The data collected involves 170 respondents currently working or have worked in O&G JVPs. The relative importance index (RII) for each risk factor’s (RF) value was quantified and the RFs ranked based on the value. A RII value exceeding 60% is considered to have agreement and of importance to the respondents. The RII value can be used as an indicator to rank the RFs from the most to the least critical. The CRF categories determined in this study are environmental, cultural and social, and organisation. Under environmental, the main CRFs are losses due to fluctuations in exchange rates/interest rates. For cultural and social, the main CRFs are problems associated with cultural differences and cooperation. Organisational issues are related to organisational fit, incompetent project management team, difficulty in finding and keeping skilled workers, and low worker productivity.","PeriodicalId":344452,"journal":{"name":"International Journal of Global Optimization and Its Application","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134042329","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}
