Abstract

Currently, the area of oil palm plantations in Indonesia is increasing. However, the condition of oil palm plantations generally has very minimal infrastructure. Therefore, a means of transporting palm fruit is needed that can move in plantation areas that have minimal infrastructure and have the ability to turn with a small turning radius. Chassis is the most important component in every vehicle. Chassis is a component used to support the load, vehicle body, engine, and driver. The development of technology in the field of engineering requires the chassis design of a vehicle to be light but strong. Therefore, this study aims to analyze the strength and safety factor of the chassis using the Finite Element Method. The software used in this analysis is SolidWorks 2018. By doing this analysis, the safety factors in the chassis design will be known. In this design, the magnitude of the factor of safety must be more than two. 3D modeling and material data are required to run the simulation of strength and factor of safety analysis. The material that will be used in the design of this chassis is ASTM A36 steel. From this research, it is expected that the chassis can withstand a maximum load of 500 kg and a maximum driver of 100 kg.

Abstract

The brake pad is a critical component in the LRV braking system. Based on maintenance data on the LRV Series 1100 shows that there is a decrease in the thickness of the brake pad. The braking system on the LRV has two types of braking, which are regenerative braking and pneumatic braking. Regenerative braking is a braking system that works by utilizing kinetic energy in motor traction. Pneumatic braking is a braking system that works by utilizing compressed air which moves the calipers and is forwarded to the brake pads to grip the disc brakes. The purpose of this study is to determine the wear rate of the brake pads so that the prediction of the service life of the brake pads is known and to find out the factors causing the differences in the wear rates of the brake pads attached to the bogie trailer and the bogie motor. The method used in this study is linear regression, by processing maintenance data and collecting data in the field so that the factors that influence the wear rate and differences in the rate of wear on the brake pads are obtained. After analyzing the data, the brake pad on the McA bogie brake pad can be achieved in November 2039 with a thickness of 8.06 mm, the McB bogie in June 2042 with a thickness of 8.03 mm, on the trailer bogie in November 2029 with a thickness of 8.12 mm. The braking force between the brake pad and disk brake on the McA and McB bogies was 98.26 kgf, the braking friction that occurred had an impact on the wear rate of the McA and McB bogie brake pads which was 1.11 x 10-6 mm3/Nm. Whereas in the bogie trailer, the braking force between the brake pad and disk brake is 25.24 kgf, the braking friction that occurs affects the brake pad wear rate of 10.01 x 10-6 mm3/Nm. The factors that affect the difference in wear rate are the regenerative braking function and the pneumatic braking itself, on bogies McA and McB brake pads work at speeds of 15 km/h to 0 km/h, while on bogie trailers from a maximum operating speed of 60km/h to 0 km /j uses the pneumatic braking function.

Abstract

Profit planning is an essential component of financial management for state-owned enterprises such as Perum BULOG, which has a strategic role in maintaining national food security and ensuring sustainable financial performance. In this context, the present study aims to analyze the minimum sales volume required by Perum BULOG to avoid losses using Cost-Volume-Profit (CVP) analysis and to develop a combined model that integrates CVP with sales forecasting through the parabola method. This combined approach is expected to provide a more comprehensive foundation for profit planning and strategic decision-making. The research employs a descriptive quantitative approach using secondary data derived from Perum BULOG’s audited financial reports for the 2019–2023 period. CVP analysis includes the computation of Contribution Margin, Break-Even Point (BEP), Margin of Safety (MoS), and Degree of Operating Leverage (DOL), which together illustrate the company’s cost structure and sensitivity to sales fluctuations. Furthermore, sales forecasting with the parabola method is applied to capture historical fluctuation patterns more accurately than linear projections, thereby generating realistic sales targets for future periods. The findings indicate that Perum BULOG consistently achieved sales well above the break-even threshold, with the lowest BEP recorded at IDR 17.68 trillion in 2021 and the highest at IDR 30.36 trillion in 2023. The Margin of Safety rose significantly from 8.65% in 2019 to 34.08% in 2023, reflecting improved resilience against sales downturns. Meanwhile, variations in DOL highlight the degree to which operating profit is sensitive to sales changes. Parabola-based forecasting projects substantial sales growth, reaching IDR 64.71 trillion in 2024 and increasing further to IDR 126.35 trillion in 2026.

Abstract

The application of the living law concept within Indonesia’s criminal law system, as regulated in the new Criminal Code (KUHP), opens a new dimension in recognizing customary law and social norms that exist within society. This concept seeks to create a legal system that is more responsive to social and cultural diversity, while accommodating local norms within the criminal justice process. However, the recognition of living law also raises significant issues, particularly with respect to the principle of legality in criminal law, legal uncertainty, and the potential for abuse of power by law enforcement authorities. This study aims to analyze the problems associated with the implementation of living law as a basis for criminalization under the KUHP, using a normative juridical approach and relying on both primary and secondary legal sources. The discussion includes the identification of challenges arising from the ambiguity in the acceptance and proof of customary norms in legal practice, as well as these norms’ impact on legal certainty and the protection of human rights. Furthermore, this article proposes alternative approaches to the application of living law that are more selective and firmly grounded in the principles of justice and human rights. The findings indicate that although living law can enhance respect for legal pluralism, its implementation must go through strict and transparent verification mechanisms to prevent legal uncertainty and discrimination. Therefore, clear regulations are needed regarding the recognition and limitations of living law norms within the criminal justice system, along with a more restorative approach to dispute resolution.
