Abstract

A pension fund program is a crucial instrument in the social security system, playing a vital role in ensuring economic stability and financial well-being for individuals in their later years. This program is designed as a form of long-term financial planning aimed at providing protection for workers after they enter retirement. Through this, workers are promised structured benefits in the form of pension funds or allowances, ensuring sustainable income security. Long-term financial planning, particularly for retirement, has become an essential need in the modern economy. This research explores the implementation of actuarial approaches in pension fund calculations utilizing Python programming to enhance the calculation process. The research aims to determine the total promised pension funds allocated across the working period to calculate funding requirements more systematically. Simulated data is used to compare manual calculation results with Python-based estimations. Python is expected to provide additional efficiency in estimating future pension needs. The findings demonstrate that actuarial calculation methods, supported by programming technology, can enhance accuracy in projections and assist in determining the appropriate amount for pension fund programs.

Abstract

This study analyzes the utilization of Python as a tool for calculating function limits, with an emphasis on the application of the SymPy and NumPy libraries. The flexibility of Python allows researchers to perform mathematical calculations efficiently, employing both the symbolic approach provided by SymPy and the numerical methods offered by NumPy. SymPy facilitates the management of complex mathematical expressions and produces accurate symbolic results, while NumPy provides speed and efficiency in executing numerical computations. With active community support and regular updates to the libraries, Python proves to be a robust and flexible environment for research in the field of mathematics. Findings from this study indicate that the combination of these two libraries not only enhances the accuracy of limit calculations but also accelerates the research process, making it a relevant choice in both academic and practical contexts..

Abstract

In everyday life, three-dimensional shapes are ubiquitous, manifesting in structures such as houses, bottles, and vehicles. These shapes, characterized by length, width, and height, represent the application of functions of two variables, particularly within spatial domains. This research employs Python programming to model functions of two variables, specifically focusing on spatial surfaces. Leveraging the Matplotlib module, graphical representations of these functions are generated, while the NumPy module facilitates mathematical analyses, including identifying extremal values, critical points, and tangent lines. Results demonstrate the efficacy of Python in efficiently modeling functions of two variables. Through this approach, readers gain insights into the inherent characteristics and behaviors of such functions within spatial contexts, thereby simplifying mathematical analyses and enhancing comprehension.

Abstract

High electricity subsidies in the national budget (APBN) pose a challenge to national fiscal sustainability. This research aims to formulate an optimization model for the Electricity Economics System (EES) that hierarchically balances the interests of the government, consumers, and producers. The methodology employs a Tri-Level Programming approach with a nested optimization strategy. Simulation results demonstrate that the model reached a stable convergence point at the 41st iteration with a zero relative change value. The national subsidy allocation was significantly reduced from IDR 68.64 trillion to IDR 24.03 trillion. Thus, this model serves as a strategic decision-making instrument that effectively represents hierarchical interactions between energy actors to produce more efficient fiscal policy solutions and support the sustainability of the national power system.
