Abstract

Optimalisasi waktu dalam keseimbangan lintasan produksi sangat penting bagi perusahaan yang bergerak di industri komponen otomotif seperti PT YYY dimana proses produksi dibuat secara massal dimana metode dan elemen-elemen kerja dilakukan berulang-ulang. Oleh karena itu keseimbangan lintasan ini harus direncanakan dengan baik supaya mampu mengefisiensikan penggunaan tenaga kerja dan memaksimalkan keuntungan perusahaan. Untuk mengatasi hal tersebut, diperlukan manajemen pengendalian produksi yang baik agar tidak ada waktu dan operator yang menganggur hingga berakibat kerugian bagi perusahaan. Line balancing merupakan penyeimbangan penugasan beberapa elemen kerja ke stasiun kerja untuk meminimalkan banyaknya work station dan mengurangi total waktu menunggu (idle time) pada seluruh stasiun kerja pada tingkat output tertentu. Penelitian ini menggunakan pendekatan kuantitatif dengan metode Rank Positional Weight (RPW). Adapun alur penelitian dimulai dari identifikasi masalah, studi lapangan dan studi literatur. Setelah melakukan studi pendekatan, kemudian dilakukan penentuan batasan masalah, rumusan masalah serta tujuan penelitian.  Nilai smoothness index yang diperoleh yaitu 590,565 menunjukkan adanya ketidakseimbangan distribusi beban kerja antar stasiun. Meskipun tingkat efisiensi mendekati batas minimal yang diterima dalam industri, nilai tersebut masih menunjukkan potensi perbaikan.   Optimizing time in the balance of the production trajectory is very important for companies engaged in the automotive component industry such as PT YYY where the production process is made in bulk where the methods and elements of work are carried out repeatedly. Therefore, this trajectory balance must be well planned in order to be able to efficiently use labor and maximize company profits. To overcome this, good production control management is needed so that there is no time and idle operators that result in losses for the company. Line balancing is the balancing of assigning several work elements to the workstation to minimize the number of work stations and reduce the total idle time on all workstations at a certain output level. This study uses a quantitative approach using the Rank Positional Weight (RPW) method. The research flow starts from problem identification, field studies and literature studies. After conducting an approach study, then the determination of the problem limit, problem formulation and research objectives are carried out. The smoothness index value obtained was 590.565 indicating an imbalance in the distribution of workload between stations. Although the level of efficiency is close to the minimum limit accepted in the industry, it still shows potential for improvement

Abstract

Employee productivity is a strategic factor in enhancing an organization's operational efficiency and competitiveness. However, human resource management in many companies remains suboptimal, particularly regarding the development of human capital quality that supports productivity. This study aims to analyze the impact of education, work experience, and job training as dimensions of human capital on the productivity of PT XYZ employees. Unlike previous studies that tended to examine human capital aspects in isolation or within specific organizational contexts, this research integrates these three dimensions into a single model to provide a more comprehensive understanding of the factors driving productivity within the study's scope. The selection of these three dimensions is grounded in Human Capital Theory, which views education as the foundation of knowledge, work experience as the accumulation of practical competence, and training as a mechanism for continuous competence development. A quantitative approach was employed, utilizing a survey of 150 respondents selected through purposive sampling. Data were collected via Likert-scale questionnaires and analyzed using multiple linear regression in SPSS. The results indicate that education (β = 0.241; p < 0.05), work experience (β = 0.356; p < 0.05), and job training (β = 0.418; p < 0.05) all have a positive and significant effect on work productivity. Collectively, the three variables exert a significant influence, with an Adjusted R-squared value of 0.682. Job training emerged as the factor making the largest contribution. These findings underscore the importance of integrated human capital development strategies in boosting organizational productivity and competitiveness.

Abstract

This study analyzes the quality control of polyurethane suspension bushing production at Han Jaya Fabrication, a home industry located in Jepara, Central Java. The main issues identified include semi-manual production processes, high operator-skill dependency, and the absence of formally documented quality control procedures. The research employs Failure Mode and Effect Analysis (FMEA), a systematic Total Quality Management approach to identify potential failure modes, analyze their effects, and prioritize corrective actions based on Risk Priority Number (RPN) values. The analysis identified 12 failure modes across five core production processes, with the highest RPN values found in bushing diameter out of tolerance (RPN=315), defective product passing inspection (RPN=315), inconsistent bushing surface quality (RPN=294), and cutting dimension non-conformance (RPN=252). Recommended corrective actions focus on process standardization through written SOPs, implementation of jigs/fixtures, preventive maintenance schedules, and multi-layer inspection systems. These findings are intended to serve as a foundation for Han Jaya Fabrication in implementing Total Quality Management (TQM) principles to improve product consistency and competitiveness.
