Abstract

Community service activities aim to provide skills to partners regarding the installation of electricity at home or residence also provide an understanding of the dangers posed by the electricity. And it is expected that the target partners will be able to transmit their abilities to the surrounding community as well as other members of the Youth Organization (Karang Taruna) from Bencongan Indah, Tangerang. The approach method in solving existing problems is by conducting Technology Transfer Methods in the form of direct training. Implementation Activities of The Community Service Program is divided into three stages, namely preparation, implementation, and stages monitoring. Participants can take part in the activity well. It can be seen from the amount of curiosity they had about the material provided. Follow-up activities are carried out after the participants have applied some of the knowledge conveyed by the Service Team. Follow-up activities are intended to determine the impact of this activity. The activity is in the form of an obligation for participants to re-practice and understand the dangers of electricity and how to secure, read installation drawings, measure voltage, detect broken connections and can install home lighting with various switches and sockets in accordance with the requirements General Electrical Installation (PUIL). The results of the evaluations that have been conducted, it can be seen that the participants' knowledge to install lighting in the house increases and opens the mind of the participants to take advantage of the opportunities available to increase income. About 85% of participants actively responded positively to the skills and knowledge conveyed by the team.

Abstract

The manufacturing sector plays a crucial role in driving Indonesia’s economic growth, particularly in facing the challenges of globalization and demands for production efficiency. One of the commonly used manufacturing processes is injection molding due to its ability to produce high-precision plastic products in large quantities. This study aims to design an injection mold for producing a two-color volume knob made from clear polycarbonate (pc) and black acrylonitrile butadiene styrene (abs), using a sumitomo demag se75du-ci two-shot injection molding machine. The product presents a high level of complexity due to the use of two different materials and the need for efficient production to minimize defects such as short shots, flash, and product weight inconsistency. To address this, the two-shot injection molding method is employed, enabling the molding of two materials in a single production cycle. The mold design process is carried out systematically using the design for manufacturing method. The mold is designed using siemens nx software and further optimized through material flow simulation using moldex3d moldflow to predict potential defects and improve the mold design. This research is expected to provide an effective mold design solution that enhances product quality, process efficiency, and reduces the rejection rate in two-color knob production. The results of this study are intended to serve as a reference for implementing multi-material mold technology in the plastic manufacturing industry, especially for components with complex designs and specific visual requirements.
