Abstract

Gamification is described as the art of changing human activity to a game-like environment to gain user engagement. Rimigs is a developed gamification system discussed in this research and was built based on Octalysis framework. This research aims to design and identify the impact of using a gamification system on students’ motivation and performance, especially in programming classes. Through Rimigs, students’ engagement and performance can be enhanced by freely choosing tasks or quests according to the rank points, completing these tasks or quests, getting experience points, getting rewards, avoiding punishment at certain times, and competing with others friends. The proposed research was done by using the iterative methodologies and consists of four phases, starting from i) literature review, which identifies the Octalysis’ core, ii) design, which identifies the game elements used in the system and designing the unified modeling language (UML) diagram of the system, iii) testing, which involve the user in the using of the system, and iv) implementation, which is the analysis step for the impact of Rimigs in students’ performance and engagement. This research finds that Rimigs as a gamification system can positively impact both students’ motivation and performance.

Abstract

The First-Person Shooter (FPS) game genre has gained significant popularity in the e-sports industry during 2022-2023. This study investigates the impact of physical environment and mouse settings on shooting accuracy in FPS gameplay. Participants were divided into beginner and advanced groups based on experience and playtime, or “flight hours.” Key variables include environmental factors—such as lighting and room temperature—and mouse settings, including mouse weight and DPI. Experiments were conducted using the AimLab application, with ANOVA and ANOM statistical tests used to determine optimal conditions. For advanced players, the ideal settings were identified as a room temperature of 16°C, no lighting, and a mouse weight of 100 grams. For beginners, the optimal condition was a room temperature of 16°C.

Abstract

PT.XYZ is one of the companies engaged in the automotive manufacturing industy, where it produces spare parts for cars, motorcycles and trucks. Along with marketing and producing the products, PT.XYZ continues to implement customer satisfaction and the quality of spare parts produced.  The company must anticipate the possibility of production capacity limitations; this must be done as well as possible at the minimum cost. For that, the aggregate heuristic planning is proposed for planning the establishment of a level for production capacity to meet the level of demand obtained from orders with the aim of minimizing total production costs. Aggregate Planning is a process of determining the level of overall production capacity to meet the level of demand obtained from forecasting and order with the aim of minimizing the total cost of production. In this study, three heuristic methods were tried, namely labor control method, subcontracting mixed method, and overtime mixed methods. Based on the results of the study it is known that the subcontracting mixed method is the best method with total aggregate cost of IDR 3,080,689,770, then the labor control method with a total of aggregate cost of IDR 3,080,798,198 and the overtime  mixed  method, with a total  aggregate cost of  IDR 3,081,815,315.

Abstract

The business process improvement at the Research and Community Services Center (LPPM), at a private university in Jakarta, was initiated due to unclear Standard Operating Procedures (SOPs) and the introduction of a new operational mechanism. The main objective of this research is to analyze and map the current business processes to clarify existing workflows. The IDEF0 method is used to identify and evaluate these processes, while the overall analysis follows Business Process Improvement (BPI) principles. The focus is on three core processes: proposal submission, fund disbursement, and reporting—each essential to research, community service, and publication activities. Improvements are proposed through the development of a revised SOP and the design of an online database system. These enhancements are based on interviews with key stakeholders, including the Head of the Center for System Development, LPPM officials, and staff. The use of the IDEF0 method significantly assists in identifying the roles and responsibilities of involved parties in each process. It provides a structured approach to evaluating and refining workflows. As a result, a new database system is being designed to support better data management and documentation at LPPM. This system will be built upon the improved processes identified through the IDEF0 analysis, ensuring more efficient and transparent operations.

Abstract

PT. SKI is a manufacturing company engaged in the production of hair and skin beauty products such as hair masks, shampoos, conditioners and others. Demand for beauty products that are increasing every day requires companies to produce more than inventory. One solution is to expand the production area in an increase large-scale production processes. However, the current production area which cannot optimally support this due to the absence of vacant land or expansion of the area that can be carried out. Based on the results of interviews with the head of the production section, the plan to move locations in several alternative places is the right solution for the company. In the specific task studied, the need for this location transfer will be related to multiple decision making taken by the company. One technique to identify these problems is using the Analytical Hierarchy Process or AHP method where this method is a simplification of complex problems that are not structured, strategic, and dynamic into their parts, and organize in a hierarchy. The level of importance of each criterion that supports decision support is relatively compared to other criteria by considering various considerations and then synthesizing to determine criteria that have high priority and play a role in influencing the results of the system. Based on the results, it is found that there are several criteria which plays an important role in the selection of factory location alternatives obtained in the mathematical equation. The first criterion namely Investment and Operations has a value of around 55.84% indicating that the first best alternative location in the sub criteria is land price, land area, expansion and employee salaries (UMR). Continued around 58.47% in the second general criteria, namely facilities with sub criteria of water, electricity, transportation and service which showed the best selection was in the first location alternative and 73.51% in the criteria for ease of licensing and transportation access at the first alternative location. By comparing the three data multiplication matrices and assessment criteria, it was found that a large comparison of the three general criteria had a total of 60.91% of the first alternatives being the priority of PT. SKI to choose the location of the new factory area, which is located in Padurenan, Gunung Sindur, Bogor, West Java.

Abstract

PT MTG is a company engaged in the gears and mechanical part component. In the current condition, PT MTG has an effort to improve the company's work efficiency through with an efficiency target of 80%. However, the current problem is that the company does not yet have the right method for evaluating and detecting factors that inhibit increased productivity on the "TMM 1" and "TMM 2" production lines. To find out the right method for PT MTG, two productivity measurement methods are used in total with the Overall Equipment Effectiveness (OEE) method and partially with the Objective Matrix (OMAX) method. In measuring productivity with the OEE method, it can be seen six big losses that occur in each machine on each production line. Whereas in the OMAX method, measurement of productivity is used 4 criteria to determine the company's productivity index, namely (1) Minimization of Defective Products; (2) Optimizing Production Capacity; (3) Efficient Use of Labor; (4) Minimize Absence of Work. Based on the results of data processing and analysis, the average overall OEE value for the "TMM 1" and "TMM 2" production lines is 0.32% and 0.321%. The OEE value still does not meet the JIPM standard of 85%. Whereas in the OMAX results, the average productivity index value of the two production lines is 140.80 per month from the optimal value of 1000. The factor influencing the two methods for not achieving the target is the amount of production per month that differs more than 55% of the production plan. Whereas in OEE, excess production is not considered a loss. So, for the current conditions the right method of measuring productivity for PT MTG is the OMAX Method.
