Abstract

Line balancing merupakan metode yang digunakan untuk mengoptimalkan alokasi pekerjaan di dalam suatu garis produksi dengan tujuan mencapai efisiensi produksi yang maksimal. Dalam penelitian yang dilakukan di PT XYZ, terdapat permasalahan ketidakeseimbangan lini produksi pada proses produksi SPK X yang dapat menurunkan tingkat efesiensi produksi. Tujuan dari penelitian ini adalah untuk meningkatkan efisiensi produksi X di PT XYZ dengan mengidentifikasi ketidakseimbangan dalam alokasi pekerjaan dan menyusun ulang urutan pekerjaan menggunakan metode Ranked Positional Weight (RPW). Metode RPW digunakan untuk menentukan bobot relatif setiap tugas berdasarkan posisinya dalam urutan pekerjaan. Diharapkan dengan metode RPW ketidakseimbangan dapat dikurangi dan efisiensi produksi dapat ditingkatkan dan dapat mengurangi waktu siklus produksi dan meningkatkan output per unit waktu. Dari hasil penelitian didapatkan efesiensi lintasan produksi 86,45%.

Abstract

Permasalahan umum yang sering terjadi pada petani kelapa dan buruh pengupas kelapa yaitu minimnya alat kupas yang membantu pekerjaan mereka dalam mengupas buah kelapa dengan mudah, cepat, aman, efektif dan efisien. Selain itu, permasalahan khusus yang dialami kelompok mitra adalah (1) minimnya produk teknologi yang dimanfaatkan petani kelapa dan buruh kupas (2) rendahnya kemampuan Sumber Daya Manusia (SDM) petani dan buruh kupas terkait dengan bidang teknologi dan manajemen (3) rendahnya kemampuan kelompok sasaran dalam pemanfaatan teknologi pertanian alat kupas buah kelapa sebagai sarana meningkatkan hasil pertanian buah kelapa. Solusi dalam program ini adalah (1) pemanfaatan produk teknologi untuk masyarakat petani kelapa dan buruh kupas di Kecamatan Cikedung Indramayu, (2) pelatihan penggunaan teknologi, perawatan dan pembuatan melalui program produk teknologi yang didesiminasikan ke masyarakat (3) peningkatan kemampuan SDM petani dan buruh dalam bidang teknologi. Produk teknologi yang didesiminasikan ke masyarakat yang telah dilakukan adalah memproduksi alat bantu kupas kelapa (LATTUPA), diklat penggunaan LATTUPA, penerapan teknologi LATTUPA dan serah terima LATTUPA kepada mitra kegiatan. Hasil yang didapat kelompok sasaran atau mitra dari program ini dapat disimpulkan bahwa warga khususnya petani atau buruh pengupas kelapa dapat mengetahui pemanfaatan alat bantu kupas kelapa (LATTUPA) dengan baik, juga warga khususnya buruh pengupas kelapa dapat mengetahui berbagai macam bagian dan manfaatnya. Alat kupas ini menurut warga berdampak pada peningkatan kesejahteraan serta ekonomi.

Abstract

Every manufacturing company must maintain product quality to meet established standards. PT Surya Gemilang Engineering is a company that manufactures various machine components, of which one is DR 58 product. While the production is ongoing, several defects were found that affected the product’s quality. This study is conducted to examine the quality control of DR 58 by applying Statistical Quality Control (SQC). There are nine types of defects identified, namely: under flange thickness, over flange thickness, scratches, not machined, through holes, blind holes, excessive groove depth, oversized dimensions, and undersized dimensions. The analytical tools used The tools applied consist of the Control Chart, Cause-and-Effect Diagram, Scatter Diagram, Histogram, Check Sheet, and Pareto Diagram. The findings reveal that the main sources of defects come from environmental, method, machine, human, and material factors. The recommended improvements include regular operator training, scheduled machine maintenance, adjustment of work methods, proper material selection, and better workplace environmental conditions. The application of SQC methods helps the company objectively identify defect sources and formulate appropriate corrective actions, thus improving the quality of DR 58 products in a sustainable manner.

Abstract

Quality control in the packaging process plays a vital role in the food industry to ensure that products meet established standards. Inaccurate weighing during packaging can lead to product inconsistency, increased waste, and reduced customer trust. This study aims to evaluate the accuracy and process capability of two packaging machines on the Consumer Pack (CP) Line 2 at PT ISM Bogasari Flour Mills using the Sixpack Report statistical approach through Minitab 22.1 software. Data were collected by direct sampling of 1,000-gram wheat flour products over three days with two speed variations (55 and 60 packs per minute). The results show that all combinations of machines and speeds had Cp, Cpk, Pp, and Ppk values below 1, indicating that the processes were not capable. Machine X recorded the highest defect rate of 36%, while Machine Y showed more stable performance but still below the industry standard. Based on Ishikawa diagram analysis, four main factors contributing to inaccuracy were identified: operator, machine, method, and material. The study concludes that improvements in operator training, machine maintenance, and shift standardization are necessary to enhance process stability and packaging quality.

Abstract

Incoming material quality is a critical factor affecting production continuity and final product quality. Nonconforming materials may increase rejection rates, raise production costs, and reduce operational efficiency. This study aims to identify the quality condition of incoming materials, determine the dominant defect type, and analyze the factors contributing to the occurrence of dominant defects in the Incoming Quality Control (IQC) department of PT. X. A quantitative descriptive approach was employed using NG Rate analysis, Pareto Analysis, and Root Cause Analysis (RCA) supported by a Fishbone Diagram. The research data were obtained from the Daily IQC Performance Report and Summary IPRR & IQC Claim Report for January 2026. The results revealed that Vendor MT recorded the highest rejection frequency and NG Rate. Pareto Analysis identified flash defects as the dominant defect category, contributing 26.43% of total defects, while the six most frequent defect types accounted for 80.07% of all incoming material nonconformities. Furthermore, RCA results indicated that flash defects were potentially influenced by material, machine, method, and human factors. The findings demonstrate that the integration of Pareto Analysis and RCA effectively supports the identification of critical quality problems and their potential causes, thereby enhancing quality control effectiveness and supplier performance evaluation.
