Abstract

Plastic bottle waste is still considered a less useful waste that causes environmental pollution. However, plastic bottle waste can be utilized to create a variety of useful products. Efforts to address plastic bottle waste include recycling it to create various value-added products. This community service program aims to provide innovative solutions by utilizing plastic bottle waste into useful products, such as decorative lamps. This community service activity aims to: (1) Achieve and achieve success in the training process for making decorative lampshades from plastic waste for housewives and youth in the Jatirahayu sub-district, Pondok Melati District; (2) Build character, skills, and abilities, and develop the potential of housewives in the Jatirahayu sub-district, Pondok Melati District. This activity is conducted using a science and technology training method in the form of lectures. This activity provides skills, knowledge, and insight into creative entrepreneurship. Based on the results of observing the products produced and the growing motivation and creative entrepreneurial spirit of the training participants, this is evidenced by the various questions asked and the success of creating economically valuable products, in this case, decorative lampshades.

Abstract

This research aims to evaluate heat input calculations in multipass Gas Tungsten Arc Welding (GTAW) on ASTM A36 steel pipe. The primary parameters investigated include current, voltage, and welding speed, incorporating a process efficiency factor (η = 0.7). The research methodology employs an experimental approach where heat input values are systematically calculated for each welding layer. The results indicate that increases in current and voltage are directly proportional to the rise in heat input, whereas an increase in welding speed is inversely proportional to it. Specifically, the highest heat input was observed in the root layer at 2.43 kJ/mm, followed by the filler layer (2.20 kJ/mm), capping layer (2.08 kJ/mm), and hot pass layer (2.00 kJ/mm). Metallurgically, these findings indicate that excessive heat input can trigger grain growth in the Heat Affected Zone (HAZ), while insufficient heat input can lead to lack-of-fusion defects. This study significantly contributes to understanding thermal energy distribution across multipass welding layers, providing a fundamental basis for determining optimal parameters to ensure high-quality weld joints.
