Abstract

PT X adalah perusahaan manufaktur yang memproduksi spring mattress. Permasalahan yang dihadapi perusahaan saat ini adalah perusahaan berkeinginan untuk meningkatkan produktivitas lini produksi perakitan spring mattress dengan cara mengurangi cycle time. Perusahaan berkeinginan pula untuk mencapai target produksi sebesar 2.241 unit/periode. Berdasarkan hasil pengukuran, kapasitas efektif perakitan spring mattress sebesar 2.019 unit/periode dan cycle time sebesar 1.928,32 detik dengan persentase waste transportation sebesar 3,03%, waste waiting time sebesar 19,62%, serta waste overprocessing dan defect sebesar 3,45%. Metode value stream mapping digunakan untuk mengidentifikasi waste yang terjadi pada proses produksi berdasarkan process activity mapping. Penerapan penggunaan alat Material Handling (MH), pengawasan dan pelatihan Standard Operating Procedures (SOP), serta line balancing dapat menghasilkan peningkatan kapasitas efektif perakitan spring mattress menjadi 2.281 unit/periode, sehingga target produksi (2.241 unit/periode) dapat tercapai, bahkan melebihi. Hal ini terjadi akibat penurunan cycle time menjadi sebesar 1.854,17 detik dengan persentase waste transportation sebesar 2,74%, waste waiting time sebesar 10,92%, serta waste overprocessing dan defect sebesar 0%. Dengan berkurangnya cycle time dan meningkatnya kapasitas produksi, PT X dapat meningkatkan produktivitas secara signifikan, tanpa perlu investasi besar dalam fasilitas produksi baru.

Abstract

PT Kahatex is a textile company that has implemented the Kaizen concept in its production process. However, in practice, partners still encounter obstacles, namely in terms of the participation of all employees in making changes and determining the right methods that are in line with the Kaizen philosophy in solving problems on the production floor. This community service activity in the form of training was carried out to provide understanding and direction to partners regarding real examples of the application of easy-to-do methods on the production floor in relation to continuous improvement. The community service activity was carried out from January 8 to 26, 2024, which consisted of the preparation and implementation stages of the training. The community service team consisted of 6 lecturers and 5 students, while the training participants consisted of 20 PT Kahatex employees. The result of this training activity was an increase in the percentage of participants who fully understand the Kaizen material and the benefits of its application as well as 5W1H and examples of its application, from initially between 15% - 25% to between 60% - 75%.

Abstract

Industrial development in the era of globalization is progressing very rapidly and is accompanied by increasing competition between companies. To maintain high competitiveness in meeting market needs, a company's operational performance must continue to improve. Research on measuring supply chain performance has been widely conducted. However, research using a combination of the SCOR model and the Objective Matrix (OMAX) and Traffic Light System (TLS) method is still limited. Therefore, in this study, a combination of the Supply Chain Operations Reference (SCOR) model with the OMAX-TLS methods will be used to measure the supply chain performance of a product packaging company. This study uses the SCOR model with weights from the Analytical Hierarchy Process (AHP) and then measures it with OMAX and TLS for performance evaluation in product packaging companies. Performance measurement is needed to improve supply chain performance. Data processing uses 29 performance indicators to measure supply chain performance. The results obtained are supply chain performance at 6.826, indicating Good performance. Indicators with a score below 3 are included in the Poor category. There are two performance indicators in the Poor category, twenty in the Good category, and seven in the Very Good category. Performance indicators that require significant improvement are indicators that fall into the Poor category.
