Abstract

The universal health social security program in Indonesia began in 2014, and as of the present day, many people are now covered by it. However, many weaknesses in the system have been pointed out. Significantly, many people do not possess the necessary health cards to take advantage of the program due to the complicated process one must go through in order to obtain them. Even now, 60 million people have not joined the program. Many people do not rely solely on the universal social security program but may be supported primarily or additionally by the vernacular care system, whereby support is provided by their family, friends and community. This study intends to understand and analyze the vernacular care system found in rural West Java, Indonesia, with particular focus being given to the elderly’s engagement with it. This study is mainly based on field work that surveyed 64 households with a socio-economic household survey being conducted alongside in-depth interviews with elderly people who received medical check-ups in 2003. This study shows the importance of care; not only that which is provided by the children of elderly parents, but also the grandchildren. In cases where children migrate from their family homes, elderly family members are supported not only through remittance, but also by having their grandchildren live with them. Otherwise, the characteristics of the informal sector occupations enable people to continue living in and around the village that their families are based so that their children, children-in-law, and grandchildren can care for the elderly.

Abstract

Biodegradable foam has been vastly developed to replace polystyrene foam. However, its water absorption capacity has become a significant obstacle to being used in food packaging. Therefore, this study aims to assess the effect of incorporating natural waxes as a coating material in producing biodegradable foams. The four natural waxes are soy wax, candelilla wax, beeswax, and carnauba wax. The biodegradable foams were fabricated with cassava starch and rice straw as natural fiber sources using a thermal pressing machine. The Meyer-Rod coating method was adopted to produce high contact angle and highwater resistance starch-based biodegradable foams. Water absorption analysis was performed according to the Cobb60, and water solubility analysis was conducted based on International Standardization for Organization 10634:2018 procedure. The result shows that the surface modification of starch-based biodegradable foams with natural waxes significantly improved water absorbency and water solubility. Moreover, it is demonstrated that the use of carnauba wax had the highest decrease of Cobb60 index of 1.5 g/m2 and the lowest water solubility of 2% after carrying water for 90 min. This study concludes that the utilization of natural waxes a as a coating material for starch-based biodegradable foam could replace conventional polystyrene foam for food packaging industry.

Abstract

Hydrometeorological disasters, such as flooding by seawater intrusion and land subsidence from excessive water resource usage, significantly disrupt maritime traffic and port infrastructure, leading to severe economic and social consequences. This study aims to develop a conceptual model for a disaster-resilient and environmentally friendly port. The primary objective is to analyze the components of the Port Masterplan (RIP), the Greenport concept, current operational conditions, and surrounding disaster threats for develop conceptual model. A mixed-methods approach, integrating quantitative and qualitative analyses, was employed. The study examined various components of the Tanjung Priok Port Masterplan, operational data, and environmental and disaster risk assessments. Observational methods involved a detailed analysis of current port operations and infrastructure, while analytical methods included Bayesian network analysis facilitated by Genie for Academic software. The primary outcomes were measured in terms of the port’s resilience and environmental friendliness, measured using Conditional Probability Table (CPT) values. This study highlights the need for integrating environmental sustainability and disaster management variables into the Tanjung Priok Port Masterplan. Notably, the study introduces two key innovations: the application of the Greenport concept and the use of Bayesian network analysis to identify causal relationships among critical variables. By incorporating these elements, the Port Masterplan can be strengthened, to ensure the sustainable and resilient development and operation of the Tanjung Priok Port. The Bayesian Network analysis revealed a strong causal relationship among the variables, indicating that the current Masterplan insufficiently addresses disaster preparedness, Specifically, the CPT values showing that only 36% of the port’s operations can be classified as resilience and environmental friendliness, while the remaining 64% fall under non-resilience and non- environmental friendliness categories.
