Abstract

Nur Medina Islamic Boarding School Pondok Cabe conducts a student quality selection process aimed at providing appreciation to the best students managed by the boarding school. However, this selection process is still carried out manually, which may lead to subjectivity and inefficiency in decision making. This study aims to design and develop a decision support system to determine high-quality students using the Simple Additive Weighting (SAW) method. The SAW method is applied because it is able to determine the best alternative based on the weighted summation of each predetermined criterion. The system design is modeled using Unified Modeling Language (UML). The results of the application of the SAW method are in the form of a ranking of students as a quality alternative with the highest V value, namely V4 = 0.78 with a participant named Ali Akbar. The developed system is expected to assist the Islamic boarding school management in selecting high-quality students objectively, systematically, effectively, and accurately.

Abstract

The increasing competition in the manufacturing industry requires companies to continuously enhance productivity in order to maintain efficiency and competitiveness. This study aims to measure the productivity level in the LED lamp production process using the Objective Matrix (OMAX) method combined with Analytic Hierarchy Process (AHP) weighting and Root Cause Analysis (RCA). The data analyzed include labor efficiency, machine utilization, product quality, setup time, and production costs during the period of January to December 2024. The OMAX calculation results indicate that the productivity index fluctuated throughout the research period, with an average value of 281. The highest index was achieved in July at 392, while the lowest occurred in October at 178. These fluctuations reveal instability in resource management and production performance. RCA, supported by the Fishbone Diagram and 5 Whys Analysis, identified the main root causes of decreased productivity: delayed preventive maintenance, inconsistent material quality, and uneven operator skills. Based on these findings, the study recommends implementing preventive maintenance scheduling, conducting regular operator training, and integrating a more comprehensive productivity monitoring system. These improvement efforts are expected to enhance process efficiency, reduce downtime, and ensure sustainable product quality. This research provides practical contributions as a reference for productivity evaluation and strategic decision-making in the manufacturing industry

Abstract

This study aims to examine the effect of workload on employee performance at PT X, a pharmaceutical distributor (Pedagang Besar Farmasi/PBF). This research uses a quantitative approach with a saturated sampling technique, involving all employees of PT X (n=11). Data were collected using a questionnaire as primary data and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with SmartPLS 4.0. Workload was measured using nine indicators, and employee performance was measured using nine indicators. The results show that workload has a positive but not statistically significant effect on employee performance (t=1.955; p=0.051). These findings indicate that, within the observed sample, there is insufficient evidence to confirm a significant effect of workload on performance at the 5% significance level. This study is expected to provide input for PT X in evaluating workload management to support performance improvement and organizational objectives.

Abstract

Selecting the right engine oil is essential for maintaining performance and extending the lifespan of automatic motorcycle engines. At Dede Extrem Motorcycle Workshop, oil recommendations are still made subjectively based on mechanic habits or preferences without systematic evaluation of technical criteria, which may cause mismatches between engine requirements and the lubricant used. This study aims to develop a Decision Support System (DSS) using the Weighted Aggregated Sum Product Assessment (WASPAS) method to determine the best oil based on six criteria: viscosity, temperature resistance, lubrication level, fuel efficiency, price affordability, and brand reputation. Using real-price data for three oil alternatives, the ranking results indicate Motul Scooter LE (A3) as the top recommendation with Qi = 0.9750, followed by Castrol Power 1 Scooter (A2) Qi = 0.9414 and Shell Advance AX7 Scooter (A1) Qi = 0.9367. In addition, a 1–5 scale evaluation test (five alternatives) shows A5 as the best alternative with Qi = 0.91 (rank 1), while A4 has the lowest score with Qi = 0.65 (rank 5). These results suggest that technical performance criteria have a stronger influence than price in determining oil recommendations. The developed system provides a more objective and consistent ranking output to assist mechanics in decision making.

Abstract

ABSTRACT Portland cement concrete pavement or more commonly called rigid pavement or Rigid Pavement, consists of a Portland cement concrete slab and a foundation layer (may or may not exist) on the subgrade. This concrete slab can use reinforcement or without reinforcement depending on the planning. This is different from flexible pavements where the stiffness of the pavement is obtained from the thickness of the subbase layers, the foundation and the surface layer. Because the most important thing is to know the load-bearing capacity of the structure, the factor that needs to be considered in designing concrete road pavements is the strength of the concrete itself. The varying strength of the subgrade or foundation has little effect on the structural capacity of the pavement (the thickness of the concrete slab). The subbase layer, if used under a concrete slab, is intended as a working floor and for drainage to prevent pumping. Pumping is the event of the release of water accompanied by subgrade grains through joints and cracks or on the pavement edge, due to deflection or vertical movement of the concrete plate due to traffic loads, after free water has accumulated under the concrete plate. Pumping can cause cavities to occur. under the concrete plate causing damage or cracks to the plate Key words: Rigid Pavement,Semen Portland,Pekerasan Lentur , Pumping.
