Abstract

Finishing workstations have two activities: cleaning and painting. Irregular work layouts cause time wasted just to move the product to be worked on. In addition, there is no permanent work layout arrangement or placement of work objects so that every day there is a change in work layout makes workers have to make adjustments again, so this will waste time and will reduce the productive time of each worker at the painting work station. The purpose of this study is to design an improvement layout that can be used for cleaning and painting work using the motion study method. The results of the motion study analysis obtained a repair work layout combining two cleaning and painting jobs into one repair layout with the placement of workpieces and work equipment according to the needs of the right and left hands, so that the resulting work movement is more effective and increases cycle time efficiency.

Abstract

All companies hope for an effective and efficient production system, but an imperfect production system means that PT XYZ must improve its production activities. The company strives to produce good products followed by a high level of productivity. In this research, we investigate a case at PT XYZ which produces hot stamping foil in the rewind section. This research found that there was waste that occurred in set-up replacement activities in production. Because it requires a long processing time, we perfected the system by implementing the Single Minute Exchange of Dies (SMED) method, then the process optimized internal activities in the set-up process. The application of the SMED concept is carried out by changing internal activities into external activities with the addition of helpers. This research aims to provide a more effective and efficient set-up replacement process so that machine downtime can be reduced. The results of this research show a 52% reduction in set-up time obtained by adding a helper with a time before implementation of 58 minutes to 30 minutes. This research concludes that SMED is effective in reducing machine set-up time and increasing the efficiency of the production process with benefits after implementing the SMED method by adding a helper of Rp. 10,649,336. In this way, implementing the SMED method helps companies increase production set-up replacement times in the rewind section.

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

Perkembangan industri ketenagalistrikan menuntut perusahaan untuk menjaga kinerja operasional yang optimal, salah satunya melalui pengelolaan beban kerja sumber daya manusia. Helper teknisi sebagai garda terdepan dalam kegiatan perawatan peralatan pembangkit memiliki risiko beban kerja fisik dan mental yang tinggi. Penelitian ini bertujuan untuk menganalisis tingkat beban kerja fisik dan mental pada helper teknisi mekanik dan kontrol instrumen di PT TJB Power Services PLTU Tanjung Jati B Unit 1–2 Jepara. Metode yang digunakan dalam penelitian ini adalah Cardiovascular Load (CVL) untuk mengukur beban kerja fisik dan Defence Research Agency Workload Scale (DRAWS) untuk mengukur beban kerja mental. Data diperoleh melalui pengukuran denyut jantung, observasi lapangan, wawancara, serta pengisian kuesioner DRAWS oleh responden. Hasil penelitian menunjukkan bahwa sebagian besar helper memiliki beban kerja fisik pada kategori ringan hingga sedang, dengan nilai CVL rata-rata di bawah 30%. Namun demikian, hasil pengukuran beban kerja mental menunjukkan bahwa mayoritas helper mengalami beban kerja mental tinggi (overload) dengan nilai DRAWS di atas 70%. Temuan ini mengindikasikan bahwa meskipun tuntutan fisik relatif rendah, tekanan mental tetap tinggi akibat kompleksitas pekerjaan dan tanggung jawab yang besar. Penelitian ini diharapkan dapat menjadi dasar bagi perusahaan dalam merancang pengelolaan beban kerja yang lebih seimbang guna meningkatkan kinerja, keselamatan, dan kesejahteraan pekerja.

Abstract

PT WXD Lisheng Ton merupakan perusahaan tekstil yang memproduksi tas kantor berdasarkan pesanan pelanggan. Permasalahan yang dihadapi perusahaan adalah jadwal induk produksi yang belum disusun berdasarkan kondisi aktual kapasitas produksi, sehingga target pesanan sering tidak tercapai. Kebaruan penelitian ini terletak pada penerapan metode Rough Cut Capacity Planning (RCCP) sebagai dasar evaluasi kesesuaian antara kapasitas tersedia dan kapasitas yang dibutuhkan pada bagian sewing. Penelitian ini bertujuan untuk menganalisis perencanaan kapasitas produksi yang optimal guna memenuhi permintaan pelanggan dengan biaya minimum. Metode yang digunakan adalah Rough Cut Capacity Planning (RCCP) dengan membandingkan kapasitas tersedia dan kapasitas yang dibutuhkan pada setiap periode produksi. Hasil penelitian menunjukkan bahwa pada periode Mei–Oktober 2025, PT WXD Lisheng Ton belum mampu memenuhi seluruh permintaan pelanggan akibat keterbatasan kapasitas pada beberapa stasiun kerja. Untuk mengatasi kekurangan kapasitas tersebut, perusahaan memiliki dua alternatif, yaitu penambahan tenaga kerja dan penambahan jam kerja lembur. Penambahan tenaga kerja memerlukan biaya sebesar Rp2.675.000 per bulan untuk setiap tenaga kerja tambahan, sedangkan penambahan jam kerja lembur memerlukan biaya sebesar Rp30.000 per jam. Hasil analisis ini memberikan dasar bagi perusahaan dalam memilih alternatif perencanaan kapasitas yang paling efisien secara biaya.
