Abstract

The execution process of fiduciary guarantees in bankruptcy cases in Indonesia faces significant legal challenges. Although Law No. 42 of 1999 on Fiduciary Guarantees grants priority rights to creditors holding fiduciary guarantees, its implementation is often hindered by unclear procedures and inconsistencies between fiduciary guarantee law and bankruptcy law. This study aims to analyze the obstacles creditors face in executing fiduciary guarantees in bankruptcy cases and to find legal solutions to enhance legal certainty for creditors. The research method uses a normative approach, analyzing relevant regulations and court rulings, and comparing fiduciary guarantee law with bankruptcy law. The results indicate that legal uncertainty, a 90-day execution suspension after bankruptcy, and the role of the receiver, which delays the execution of fiduciary guarantees, are the main barriers. Therefore, it is recommended to implement legal reforms that provide clearer and more efficient execution procedures and ensure better protection of creditors' rights in bankruptcy situations. Thus, this study contributes to improving the fiduciary guarantee legal system in Indonesia.

Abstract

Gravitational water vortex turbines are environmentally friendly power generation systems that convert the energy of vortex water flow into mechanical energy using turbine runners. This study aims to analyze the effect of a two-stage configuration with varied radial runner positions and water discharge on turbine performance. Experiments were conducted using a low-speed water channel with a conical basin to generate vortex flow. Savonius-type runners were installed vertically in two stages with radial positions of 0.5, 0.6, and 0.7 relative to the basin radius. Each configuration was tested at several water discharge rates. The primary parameter measured was mechanical power output, which was obtained using torque sensors and rotational speed meters to provide precise data. Results showed that the radial position 0.5 produced the best performance, generating 12.28 watts in the first and 16.68 watts in the second. Runner position and water discharge directly influenced vortex stability and energy conversion efficiency. The two-stage configuration with optimal runner placement significantly improved system efficiency. These findings suggest that the two-stage vortex turbine design is promising for small-scale power generation in remote areas.
