<![CDATA[Badan Penyelenggara Jaminan Sosial (BPJS) is a legal entity that has been provided by the government for the community with the aim of providing protection for all workers in Indonesia from certain socio-economic risks. National development, marked by planned and continuous strides, embodies a commitment to engage all societal, national, and state levels in fostering progress. Encompassing political, economic, socio-cultural, and defense and security realms, the development is meticulously designed to be comprehensive, targeted, integrated, gradual, and sustainable. The overarching objective is to catalyze an augmentation of national capabilities, align the standard of living for the Indonesian people with developed nations, and elevate overall welfare. To establish premium rates, a method involves multiplying the conditional expected value of claim frequency by the size of the claim, considering observed risk characteristics. A claim, in this context, constitutes a formal request to the insurance company, seeking payment in accordance with the terms of the agreement. The primary objective of this study is to establish the insurance premium rates applicable to policyholders (the insured) through the estimation of parameters in the distribution governing aggregate claims. This involves the distribution of both the number of claims and the size of the claims, and the estimation is performed using the moment method. Premium computations are executed based on two key principles: the pure premium principle and the expected value principle. This research produces the conclusion that the Poisson-Gamma aggregate claims distribution has a premium amount of 3.61 times greater than Poisson-Exponential due to the application of the anticipated value principle, namely IDR 4,403,542.94 per month and IDR 1,219,878.45 per month, respectively.]]>

<![CDATA[Prosperity in retirement is one of the important aspects to achieve in the career path of every individual, including the Indonesian National Army (TNI) which relies on pension funds as a source of post-retirement income. Pension funds manage programs that promise financial benefits to participants after they retire. In this context, the study aims to present the calculation of pension funds for TNI class IIIA using the Individual Level Premium method. This method allocates the total pension benefit equally each year. As a result, it is found that the Individual Level Premium method provides a greater pension benefit value than the benefit value using the proportion of salary from ASABRI. This shows that this method is effective in calculating retirement benefits.]]>

<![CDATA[This study aims to analyze the application of the Projected Unit Credit (PUC) Method and the Entry Age Normal (EAN) Method in the context of pension fund insurance. The Projected Unit Credit Method and the Entry Age Normal Method are two actuarial approaches used to calculate liabilities and determine the required contributions in pension plans. The Projected Unit Credit Method calculates based on projected future salaries and benefits accumulated over the employee's working life, while the Entry Age Normal Method distributes the cost of retirement benefits evenly over the employee's working life. Data was collected from various pension plans that use both methods. Analysis was conducted to compare the accuracy of liability estimation, contribution stability, and the impact of each method on pension fund sustainability. The results show that the Projected Unit Credit Method provides a more realistic liability estimate by considering salary increases, while the Entry Age Normal Method offers better contribution stability from year to year. The selection of the appropriate actuarial method is highly dependent on the objectives and specific conditions of the pension program being managed. These findings are expected to help pension fund managers make more informed decisions to ensure the welfare of pension plan participants.]]>

<![CDATA[The purpose of this study is to measure the ability of the Capital Asset Princing Model (CPAM) in analyzing investment decision making by predicting the risk and return that will be obtained by investors and helping investors in choosing efficient and inefficient stocks. CAPM is a measuring tool that can be used to determine the level of risk and return obtained and evaluate the rate of return on investment. The purposive sampling technique is used in selecting samples to be used in the study, namely companies listed on the Indonesia Stock Exchange and their shares are consistently included in the Bisnis-27 stock index. The stock criteria used in selecting efficient stocks, namely when individual return results exceed the expected return. The results of this study indicate that there are 8 stocks that meet the efficiency criteria, namely ADRP, AKRA, AMRT, BBNI, BMRI, INKP, JSMR, and PGAS with individual returns results exceed the expected returns. In investment decisions, stocks that are included in these efficient stocks are the priority stocks that investors should buy. Based on the analysis, there is a non-linear relationship between systematic risk and expected stock returns, making an important contribution to investment decision making in the Indonesian stock market.]]>

<![CDATA[The study on "Integrated Financial Strategies: Sinking Funds and Annuity Pricing in a Dynamic Market Environment" seeks to investigate how sinking funds, annuity pricing, and dynamic market environments can be integrated within the context of integrated financial strategies. The study focuses on the following areas: (1) the application of actuarial tables and probability distributions to ascertain the proper values for annuities payments and sinking fund balances; (2) the role of the actuary science in sinking funding scheduling; (3) the effect of market factors, such as interest rates, inflation, and economic conditions, on the value and value of sinking investments; (4) the analysis of the relationship between market dynamics, including interest rates and time periods, and the value of a sinking asset, including the integration of the two financial instruments. The analysis revealed that changes in the interest rate and the number of periods directly influence the future value of the sinking assets. The integration of these financial instruments can help to optimize financial decision-making, enhance risk management, increase investment returns, improve financial planning, and lead to greater integration with other financial instruments, ultimately leading to better financial outcomes for both financial professionals and investors]]>
