Abstract

Effective project management planning is a key element in the success of a project. Among the stages of project management, scheduling activities has an important role in ensuring the project runs according to plan. One of the methods used in determining the optimal time of project work is the Critical Path Method (CPM), which helps in calculating the estimated time of each activity and determining the critical path of the project. This study aims to examine the planning and implementation of the Field Work Practice Program at SMK Cendekia Batujajar, focusing on time management and constraints that may occur. The research method used is quantitative with a descriptive approach. Data were collected through observation and document analysis related to the planning and implementation of PKL at SMK Cendekia Batujajar. The results showed that the planning of the PKL program has been carried out based on government regulations and industry needs, with details of activities that have been compiled in the schedule. Through CPM analysis, the estimated project completion time is 242 days, with the identification of critical paths that must be considered in maintaining the project schedule. Based on the analysis, the planning of the PKL program at SMK Cendekia Batujajar has been carried out in a detailed and systematic manner, with the use of the CPM method to identify the critical path. However, challenges in time management and other constraints need to be considered in the implementation of the PKL project at the school.

Abstract

This research aims to analyze the quality of tumbler products at PT Bintang Mitra Kencana and identify factors that influence the occurrence of defects in products. The research method used is a quantitative method with a descriptive research design. Data was collected through documentation and interviews with two informants who were the General Director and production staff at the company. This research uses several Seven Tools quality control tools (check sheets, histograms, Pareto diagrams, control charts, scatter diagrams, stratification diagrams, and cause-and-effect diagrams), as well as attribute control charts (P Chart). The research results show that the most common defects in tumbler products in the company are powder pest defects. Factors that cause defects include a lack of understanding by the workforce regarding raw material care, a lack of clear methods and procedures in the production process, the use of wet raw materials, the use of poorly maintained machines, and an unclean storage environment. Several efforts to improve human factors require training and education for employees, increased supervision and monitoring during the production process. For method factors, it is necessary to develop clear operational standards and appropriate process parameters. For raw material factors, it is necessary to carry out proper drying and appropriate storage. For engine factors, it is necessary to carry out routine maintenance and periodic cleaning. And for environmental factors, it is necessary to arrange a suitable storage environment. By carrying out the recommended corrective actions, it is hoped that we can reduce the level of defects in tumbler products at PT Bintang Mitra Kencana and improve overall product quality.

Abstract

This study examines the selection of the optimal camera for the photography and videography service company Assad ID using a combination of the Analytical Hierarchy Process (AHP) method and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The rapid development of the photography industry makes choosing the right camera a crucial factor in improving the quality of service. The weighting of criteria using AHP is based on the evaluation of photography and videography experts, including technical specifications, functional features, economic aspects, comfort, and supporting services. The TOPSIS method is applied to the ranking of five alternative cameras (Sony A7 III, Canon EOS R6, Nikon Z6 II, Panasonic Lumix S5, and Fujifilm X-T4). The results of the study show that technical specifications and functionality features have the highest weight. Sony A7 III ranked first with a preference value of 0.610, followed by Canon EOS R6 (0.581), Fujifilm X-T4 (0.472), Nikon Z6 II (0.401), and Panasonic Lumix S5 (0.368). This study proves the effectiveness of the AHP-TOPSIS method in making optimal camera purchase decisions and can be a reference for similar companies in determining the investment of photography and videography equipment according to operational needs
