Abstract

This community service program was carried out at SDN Pengasinan 1, Depok, with the aim of instilling financial literacy in elementary school students from an early age. The activities were designed to be contextual and engaging, including storytelling, saving simulations, the use of activity books and educational piggy banks, as well as a modified Monopoly game. This participatory approach enabled students not only to understand basic financial concepts, but also to practice them in daily life. Interviews with students revealed high enthusiasm; they expressed enjoyment in receiving piggy banks and activity books and acknowledged the importance of saving and managing pocket money. Questionnaire results further indicated that most students strongly agreed the materials were clear, relevant, and beneficial. Overall, the program successfully enhanced students’ financial awareness, encouraged saving habits, and provided practical tools to support responsible money management.

Abstract

In this research, a 10-year endowment life insurance’s premium will be calculated with a DARA function according to principle of utility equivalence. The calculation results will be performed using a Vasicek interest-based model, among male and female policyholders within the age range of 20-80 years old, and over varying benefit levels. Indonesian Mortality Table IV 2019 is used as reference for mortality data. Stochastic interest is modeled using the Vasicek Model derived through Ordinary Least Square Method (OLS) Method from BI-Rate in the volatile September 2022 - August 2024 period with a monthly step time, which yields the following parameters: , , , resulting in a 95% confidence interval  with standard error . This  indicated high uncertainty in the interest modelling. The results showed that premium rate is heavily affected by this volatility in the interest rates. Premium value is higher for male than female policyholders and it increases faster at higher entry age due to an increase of the mortality rate. The relation between the DARA coefficient and premium value is non-linear despite a slight increase in premium when a larger coefficient is chosen. An increase of benefit rate is followed by a nearly proportional increase of the premium rate. Further research on this topic could analyze the impact of policy horizon and wealth on the premium rate or compare the results with another stochastic model (e.g. CIR model).
