Abstract

A lathe machine is a tool capable of cutting metal into specific shapes, qualities, and dimensions as planned. Damage to a lathe machine is often difficult to identify and requires specialized handling; it typically needs to be transported to a workshop, which is both time-consuming and labor-intensive. Therefore, it is necessary to develop an expert system using the Forward Chaining algorithm to diagnose malfunctions in lathe machines. Forward Chaining is an inference method that initiates tracking by tracing data based on the facts of the observed symptoms. These symptoms are compared against standard rules and processed to generate solutions for the identified issues. The expert system is designed as a web-based application using the PHP programming language and a MySQL database. This system is intended to assist lathe machine operators and novice mechanics in identifying and addressing damages based on observed symptoms. Validation testing of this web-based expert system yielded a result of 83.3%, demonstrating its effectiveness in assisting users.

Abstract

During the "Digital Leap Workshop: Build Your Online Store, Boost Your Sales" community service activity held at Rumah Quran Qolbun Salim, a key focus was the use of TikTok Shop and the Affiliate Program as digital sales and marketing tools for elderly participants and retirees. The activity demonstrated that participants gained a fundamental understanding of TikTok Shop as a platform integrating e-commerce with video content, as well as the TikTok Affiliate program as an opportunity to generate income without needing to own their own products. Participants were introduced to the initial steps of account creation, product selection, simple content creation, and the mechanics of sales commissions. They showed growing interest and enthusiasm for these relatively easy and flexible sales and promotional models. The material was presented using a practical, step-by-step approach, allowing participants to follow along at their own pace. This activity offered a realistic and suitable digital business alternative for the elderly and retirees, while opening up opportunities for additional income through the wise and sustainable use of TikTok Shop and affiliate programs.
