As a strategic commodity, salt in Indonesia faces the challenges of increasing imports rather than the capacity to produce locally, which SMEs almost produce. Therefore, the research explored the extent of the government’s role in the competitiveness of salt SMEs. The research applied a descriptive method with a qualitative approach. For policy analysis, literature review, observation, and in-depth interviews were conducted to analyze the effectiveness of government policies using Regulatory Impact Assessment (RIA) and Cost-Benefit Analysis (CBA). The results find that at least six issues on the existing policies need concern. It consists of local people who are allowed to produce salt, the President Decree 69/1994 role and position, the salt consumption, which is mandatory to have SNI, the changeable salt classification, the other SNI than voluntary iodized consumption salt, and SNI for food-grade salt and caustic soda (chlor-alkali products). The situation shows the government’s significant role in influencing the competitiveness of sustainable salt SMEs. Subsequently, the research proposes recommendations for the sustainable competitiveness of Small and Medium Enterprises (SMEs) on salt industry development, such as arranging new regulations or revising the existing regulation by integrating and harmonizing the interest cross-ministries, establishing the task force under the Coordinating Ministry for Economic Affairs or directly under the president to prepare the national salt industries development. The national salt classification needs to be considered as the applicable classification internationally. Salt is salt, so there is no need to differentiate it into local and imported salt. Therefore, the imported salt can be classified into food-grade and Chlor-Alkali products (CAP) salt, which should meet international standards and be mandatory.
The problem that arises in the Cox model is that there are more than two types of covariates and the presence of random effects is a non-proportional hazard (NPH). One example of a case that involves many factors is student retention. Low student retention can lead to dropping out of college or failure in completing studies. The purpose of this study is to overcome the problem of NPH caused by the presenceof time-independent covariates, time-dependent covariates, and random effects. The research method uses simulation. Some of the modified models are the stratified Cox model, the extended Cox model, and the frailty model. The developed model is applied to distance education student retention data. The results of the study show that frailty and study programs provide considerable diversity in explaining thetotal diversity of the model. It can be concluded that frailty needs to be considered by UT to improve the quality of services to students. In addition, other covariates that have a significant effect on UT student learning retention modeling are age, domicile, gender, GPA, marital status, employment status, number of credits taken, and number of registered courses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
