PENGARUH PENGURANGAN KARYAWAN DAN MOTIVASI KERJA TERHADAP KINERJA KARYAWAN DI PT. TELKOM (PERSERO) WITEL ACEH

2026-02-06T18:35:47+08:00

PT Telkom Indonesia (Persero) Tbk Witel Aceh experienced a reduction in the number of employees due to organizational transformation and human resource restructuring. The number of permanent employees decreased from 51 in 2022 to 22 in 2025, representing a decline of 59%. This condition potentially increases workload and may affect employee performance. This study aims to analyze the effect of employee reduction and work motivation on employee performance at PT Telkom Indonesia (Persero) Tbk Witel Aceh. A quantitative approach was employed using a survey method with a census technique involving all 22 permanent employees. Data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS software. The results indicate that all measurement indicators meet validity and reliability criteria. The structural model shows an R-square value of 0.63, indicating that employee reduction and work motivation explain 63% of the variance in employee performance. Hypothesis testing reveals that both variables have a positive and significant effect on employee performance. This study concludes that effective management of employee reduction and enhancement of work motivation are important to maintain employee performance during organizational transformation

PERANCANGAN DASHBOARD MONITORING KINERJA OPERASIONAL BERBASIS SUPPLY CHAIN OPERATIONS REFERENCE (SCOR) PADA KEDAI KOPI HALAMAN PERTAMA

2026-07-09T12:13:25+08:00

This study aims to design an operational efficiency monitoring dashboard based on the Supply Chain Operations Reference framework at Kedai Kopi Halaman Pertama. The research uses operational data from July to December 2025, which were processed and visualized using Power BI. The results show that the dashboard is able to present operational performance information in a structured manner and assist the business owner in monitoring cost efficiency and service time. The proposed dashboard can be utilized as a data-driven monitoring tool to support more systematic and measurable operational decision- making in small and medium enterprises.

ANALISIS PENGENDALIAN DEFECT DEFORMASI PADA BRACKET SENSOR BLIND SPOT MONITORING (BSM) DENGAN METODE FMEA DAN SIKLUS PDCA DI PT XYZ

2026-02-12T14:32:02+08:00

PT XYZ is one of the automobile assembly manufacturers in Indonesia that bears a significant responsibility to ensure every vehicle produced complies with international quality standards. One of the major challenges in the assembly process is the occurrence of deformation-type defects on the Blind Spot Monitoring (BSM) sensor bracket. This deformation may aris due to various factors, such as improper installation processes or inappropriate component handling conditions along the production line. If not properly controlled, deformation of the bracket not only degrades the functionality of the BSM sensor but also leads to increased repair costs, production delays, and potential product recalls, which could result in substantial financial losses for the company. Based on trace-back defect analysis, the defect was identified to originate in the body production and inspection departments, specifically at the right-hand (RH) side member line. Furthermore, the Failure Mode and Effects Analysis (FMEA) indicated that the factors with the highest Risk Priority Number (RPN), and therefore the main improvement priorities, were related to man (human factors) and method (process-related factors). Following the implementation of improvement actions, the deformation defect was successfully reduced and completely eliminated, achieving a 100% defect reduction, from 0.0024 defects per unit (d/u) to 0 d/u throughout the observation period.

IMPLEMENTATION OF TOTAL PRODUCTIVE MAINTENANCE IN EVALUATION OF EXCAVATOR HEAVY EQUIPMENT MAINTENANCE PERFORMANCE USING OVERALL EQUIPMENT EFFECTIVENESS

2026-07-09T11:55:38+08:00

In construction projects, productivity, operational continuity, and maintenance costs are significantly influenced by heavy equipment reliability. Since excavators are among the most frequently used machines, efficient maintenance management is crucial to reduce downtime and improve operational effectiveness. This study uses Total Productive Maintenance (TPM) techniques and Overall Equipment Effectiveness (OEE) evaluation to assess excavator maintenance performance and develop appropriate maintenance improvement solutions. Using operational and maintenance data collected from an excavator operated by a heavy equipment rental company over a four-month observation period, a quantitative case study was conducted. Three key indicators were used to assess maintenance performance: availability, performance, and quality. These indicators were combined to estimate the OEE value. Priorities for maintenance improvement were then determined using this analysis. The study found that equipment availability increased from 94.19% to 97.32%, indicating a decrease in downtime due to maintenance activities. However, the average Quality Ratio was approximately 87%, while equipment performance remained relatively stable at approximately 72%. Therefore, the OEE value was below the acceptable operational threshold, ranging from 58.06% to 61.44%. These results indicate that although OEE has been successfully increased through improvement efforts, operational efficiency and process quality still need to be significantly improved. To improve equipment reliability and operational efficiency, recommended strategies include autonomous maintenance, planned maintenance, quality maintenance, and operator training.
