Operations Research: International Conference Series (ORICS) is published 4 times a year and is the flagship journal of the Indonesian Operational Research Association (IORA). It is the aim of ORICS to present papers which cover the theory, practice, history or methodology of OR. However, since OR is primarily an applied science, it is a major objective of the journal to attract and publish accounts of good, practical case studies. Consequently, papers illustrating applications of OR to real problems are especially welcome. In real applications of OR: forecasting, inventory, investment, location, logistics, maintenance, marketing, packing, purchasing, production, project management, reliability and scheduling. In a wide variety of environments: community OR, education, energy, finance, government, health services, manufacturing industries, mining, sports, and transportation. In technical approaches: decision support systems, expert systems, heuristics, networks, mathematical programming, multicriteria decision methods, problems structuring methods, queues, and simulation.

Indonesia is an area prone to earthquakes because it is traversed by the meeting point of 3 tectonic plates, namely: the Indo-Australian plate, the Eurasian plate and the Pacific plate. An earthquake is an event where the earth vibrates due to a sudden restraint of energy in the earth which is characterized by the breaking of rock layers in the earth's crust. Almost all regions in Indonesia are at risk of being exposed to earthquakes. To anticipate the risk of natural disasters, earthquakes are advised to join the insurance program provided by the insurance company. This study aims to determine earthquake insurance premiums based on large physical and economic losses. The method used is the Bayesian method. This method produces each estimated loss value which is then used to calculate the combined estimated loss value. After that, the combined estimated loss value is used to calculate the premium value. The result of this research is the premium which is calculated based on the principle of expected value and standard deviation principle. The premium resulting from the expected value principle is lower than the premium resulting from the standard deviation principle.

The low nutritional status of toddlers indicates a non-optimal level of health. Family empowerment is the key to toddler care to improve nutritional status. Kia books are an excellent medium for monitoring nutritional status (Susilo et al., 2021). Cibeet Village is the village with the highest cases of malnutrition in the Ibun health center area of Bandung regency with toddler visits to posyandu only 50%. MCH books were used in this study to monitor the nutritional status of toddlers. The study was designed using an analytical crossectional study, with a sample of 57 mothers under five and family. Samples from each of these villages were randomly selected and re-selected from each posyandu. Data related to the use of Kia books by families are carried out through observation of family members and direct measurement of nutritional status. The results showed that mothers of toddlers who used MCH books periodically were 42.1%, mothers were family members who used MCH books 89.5%, nutritional status of toddlers 84.2% were bai k nutrition. Based on the analysis of the relationship between the use of MCH books and the nutritional status of toddlers, a p-value (0.00 0) was obtained, < with an alpha value (0.05). Thus there is a relationship between the use of MCH books and the nutritional status of toddlers. There is a relationship between the use of kia books and toddler caregivers obtained p-value (0.00 4) < alpha value (0.05). Kurang from half of the families of toddlers have not used the MCH book as a medium for determining the nutritional status of toddlers and there are still toddlers with malnutrition, in Cibeet village, the working area of the Ibun Health Center. Efforts are needed to empower families in utilizing Kia books so that family participation increases in maintaining family health.

Nowadays, the concept of human security is an issue that is often discussed, especially when issues regarding policies or how a country deals with the Covid-19 pandemic make headlines in every news report. The concept of human security shifts the focus point of security which previously focused on the state to become towards individuals. Often various discussions collide these two concepts under the pretext of finding the best way for the state to make an appropriate policy, especially during emergencies such as problems caused by the Covid-19 Pandemic. So to solve this problem it is necessary to re-understand the priorities in the security of a country in an emergency situation, especially in Indonesia. This paper aims to find out what is prioritized by the state in the event of an emergency. Literature study or desk research becomes a research method, accompanied by a conceptual and regulatory approach, then secondary data is analyzed descriptively. Based on the research, it was concluded that the concept of state security or human security should not be made as if they are contradictory but instead complement one another and become a thinking construct for the state to determine a priority in order to achieve common interests through an insecurity faced in an emergency situation. The state as the shelter of an individual certainly needs to be a top priority without neglecting the security of every individual in it. The difference in focus on the concept of state security and human security should not make both of them an option.

Employment sosial security is a basic right of workers/laborers whose fulfillment must be guaranteed by the state in order to realize the welfare of workers/laborers and their family members. In addition, sosial security as a sosial protection system not only reduces poverty but also protects people from falling into poverty (Haiyani, 2022). Indonesia already has Law Number 40 of 2004 concerning the National Sosial Security System (UU 40/2004) and Law Number 24 of 2011 concerning Sosial Security Administering Bodies (UU 24/2011). One of the rights of workers is to get work accident insurance if they have an accident related to their work. However, what if the worker is exposed to COVID-19 at work? what if when you are hospitalized due to a work accident, you are exposed to COVID-19?. This paper is intended to analyze the need and different arrangements for the Obligations and Rights of workers in the event of having a work accident during the COVID-19 pandemic, which has not been regulated in Law Number 24 of 2011 concerning the Sosial Security Administering Body (Law No.24/2011), which is a public legal entity that has the authority as well as the obligation to implement employment social security. This research uses normative juridical research methods.Â

Justice in the legal context is to bring out a caring attitude from the state and this is important in the post-pandemic era. The state has the ability to exercise control over all things as its natural state but must still pay attention to the condition of society. Justice must be an inseparable part of a country because of the existence of a social contract from society. The research object is a country with a normative research method that makes legal hermeneutics a problem solving. As a result, the state cannot impose its will in the post-pandemic era because the people have done what the people want, including vaccines, using masks or maintaining attitudes in daily life. The conclusion obtained is that there is a prioritization of the meaning of the social contract so that the essence of justice appears and has a good impact on society.
