Abstract

Used cooking oil is cooking oil that is no longer suitable for use because it has undergone changes in physical and chemical properties during the frying process. Used cooking oil is a hazardous and toxic waste; consuming it can cause negative impacts on health and disposing of it carelessly can cause environmental pollution. However, public knowledge about the dangers and impacts of used cooking oil is still minimal. A study showed that there are still many people who dispose of used cooking oil on the ground and waterways. Therefore, the activity designed by the PKM team of Universitas Pembangunan Nasional Veteran Jakarta aims to increase public knowledge about the dangers and impacts of used cooking oil and provide solutions to reduce the pollution of used cooking oil waste. This activity was carried out in the Grand Pakis Residence housing complex using socialization and training methods. In this activity, the PKM team invited representatives from the Jalantara foundation as speakers to explain the impact of used cooking oil on the environment and health to the community. Not only that, the community was also given a training on processing used cooking oil into other products as a solution to reduce used cooking oil waste. The result of this activity is that the knowledge of residents about the dangers of used cooking oil for the environment and health has increased by 80.95%. In addition, the residents also know how to reduce used cooking oil by turning it into useful products such as soap.

Abstract

With the growing demand for energy and the need to transition to renewable sources, ocean wave energy presents great potential. The Oscillating Wave Surge Converter (OWSC) is a promising technology due to its nearshore applicability, structural simplicity, and robust design. This study systematically investigates the effect of flap thickness on the dynamic performance of a hinge-mounted OWSC using the Boundary Element Method (BEM).   The research models the hydrodynamic interactions and analyzes the effects of three different flap thicknesses on key metrics, including maximum angle deviation, angular velocity, torque, and power capture. The results indicate that all flap variations demonstrate stable oscillatory movement, but greater flap thickness reduces the maximum angle deviation due to increased inertia and hydrostatic pressure. A resonant peak was observed for all thicknesses at a wave period of 1.3 seconds, where energy transfer was maximized. At this frequency, the thickest flap achieved the highest efficiency (78.94%), followed by the intermediate (77.50%) and thinnest (70.77%) variations. The findings suggest that while flap thickness influences efficiency, the primary factor for maximizing energy capture is the alignment of the wave period with the device's natural frequency.
