Abstract

In the current era of globalization, the industrial sector has undergone rapid and significant development. This progress encourages companies to improve productivity, product quality, and operational efficiency. However, such advancements are often accompanied by the use of modern technology, hazardous materials, and complex work processes, which inevitably increase the potential for workplace accidents if not properly managed. The larger the scale of an industry, the more complex the potential hazards become, thus elevating the level of risk. Occupational Safety and Health (OSH) is a critical aspect that must be prioritized to protect all workers within the workplace environment. Despite its importance, the implementation of OSH practices remains inadequate in many institutions. This lack of attention has led to numerous workers failing to apply safety protocols for their own protection. Furthermore, the use of Personal Protective Equipment (PPE) is essential in mitigating occupational hazards and plays a significant role in ensuring workplace safety and health (Ramli, 2010). Unfortunately, the level of worker compliance with PPE usage is still relatively low, which consequently increases the risk of accidents and injuries. Given these conditions, the implementation of OSH and proper PPE usage is urgently needed at PG. Jatitujuh. The nature of work activities and the production materials used at this facility present considerable opportunities for hazards and risks that could potentially endanger not only the workers within the plant but also the surrounding community.

Abstract

The metalworking process plays a crucial role in the production of machine components, particularly when using a lathe. Continuous innovation is essential to improve the quality of production outcomes. Various methods can be applied, such as selecting the appropriate cutting tool type, determining the depth of cut, and setting the correct spindle speed. The main issue lies in how variations in tool type, spindle speed, and cutting depth affect the surface texture and hardness of the work material during conventional turning operations. This study focuses on the design of a meat chopper blade and a direct examination of the stages involved in its manufacturing process using a manual lathe. The methodology employed to collect data in this research includes systematic observation of the subject to directly ensure the planned investigation, followed by interviews involving direct question-and-answer sessions with technicians and factory managers, as well as a literature review that requires gathering information from relevant books and online resources. The purpose of the meat chopper blade manufacturing procedure is to identify the material used, ensure the proper tools and machines are applied, and describe each stage of the blade-making process. The manufacturing process involves preparing the materials, carrying out cutting procedures, performing turning operations, conducting milling activities, executing drilling processes, applying hardening treatment, and completing finishing operations.In this study, the meat chopper blade is manufactured using ST 37 steel. The process begins with material selection, followed by manual turning, rough turning, finishing turning, center hole boring, deep turning, drilling on four sides, and surface turning. The process continues with blade shaping using a grinding machine to remove excess material, and concludes with the final finishing stage, which includes grinding and polishing.

Abstract

Public services are an obligation of the village government to fulfill the needs of the community in accordance with laws and regulations. One form of service is community complaints that function as a means of conveying complaints and aspirations of citizens. In Kertabasuki Village, Majalengka Regency, the complaint mechanism is still carried out manually through face-to-face, telephone, and short messages, so the follow-up of complaints is not optimal. Data from mid-2023 to 2024 recorded 50 reports of street lighting, 7 losses, 2 floods, and around 100 related to social assistance. This condition shows the need to utilize technology to improve service effectiveness. A community complaint website is a relevant solution because it facilitates recording, tracking, and monitoring the status of reports, and supports village government transparency and responsiveness.

Abstract

Koperasi WIN Syariah, a cooperative for the employees of SMK Widya Nusantara Sumedang established in 2007, plays a vital role in improving the welfare of its members through its mini bank and school supply business units, operating on Wadi'ah and Mudharabah principles. However, its operational processes, including the management of member data, savings, and loans, are still conducted manually. This traditional approach leads to significant challenges, such as time-consuming data management, a high potential for human error in transaction recording, and inefficiencies in financial reporting. In response to the rapid advancement of technology, the integration of an information system has become essential to address these issues. This paper details the development of a web-based Savings Management Information System for Koperasi WIN Syari’ah. The system is designed to automate and streamline core cooperative functions, from member data administration and transaction processing to the automatic generation of financial statements. The objective of this system is to provide a comprehensive solution that mitigates the problems associated with manual record-keeping. It is expected that the implementation of this information system will significantly enhance operational efficiency, improve data accuracy, and provide more transparent and timely financial reporting, thereby supporting the cooperative's mission to advance the prosperity of its members.
