Abstract

Inventory record inaccuracy remains a critical challenge in warehouse operations due to the complex interaction between human factors and warehouse systems. This study aims to analyze the contribution of human and warehouse system factors to inventory stock discrepancies at PT. LOGISTIC’s warehouse using a descriptive–analytical case study approach. The research adopts the DMAIC framework combined with root cause analysis to identify operational weaknesses affecting inventory accuracy. The results indicate that human-related issues, including data input errors, non-compliance with standard operating procedures, and limited verification practices, constitute the dominant sources of inventory discrepancies. In parallel, warehouse system limitations such as delayed WMS synchronization, scanner reliability issues, and insufficient system validation mechanisms significantly contribute to data inaccuracies. The improvement in inventory accuracy from 97.45 percent in the first count to 98.55 percent in the second count demonstrates that manual verification remains essential, highlighting the reactive nature of existing control mechanisms. These findings suggest that effective inventory control requires an integrated approach that aligns human competence, standardized operational processes, and system optimization to achieve sustainable inventory accuracy.

Abstract

Pengelolaan persediaan pakan ikan merupakan faktor penting dalam keberhasilan usaha budidaya ikan, khususnya pada usaha mikro, kecil, dan menengah (UMKM). CV. Ken Fishendly sebagai usaha budidaya ikan hias dan konsumsi masih menghadapi permasalahan persediaan berupa overstock dan stockout akibat sistem pemesanan yang belum optimal. Penelitian ini bertujuan menganalisis sistem persediaan pakan ikan, menentukan jumlah pemesanan optimal menggunakan metode Economic Order Quantity (EOQ), menentukan Safety Stock (SS), serta menentukan Reorder Point (ROP). Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan data primer berupa data pemakaian pakan, biaya pemesanan, biaya penyimpanan, dan lead time selama periode penelitian. Hasil penelitian menunjukkan jumlah pemesanan optimal (EOQ) sebesar 127 karung untuk pakan Hi-Pro-Vite 781 dan 135 karung untuk pakan Hi-Pro-Vite 782. Safety Stock yang diperlukan masing-masing sebesar 8 karung dan 12 karung, sedangkan Reorder Point sebesar 14 karung dan 23 karung. Penerapan metode EOQ, Safety Stock, dan ROP mampu meningkatkan efisiensi pengendalian persediaan dengan meminimalkan risiko kelebihan dan kekurangan stok.

Abstract

Noise issues in vehicle instrument panels remain a critical challenge in automotive interior quality, particularly in the form of rattle and squeak phenomena that affect customer perception and product reliability. This study examines the root causes of instrument panel noise through an integrated application of Why-Why Analysis and Fishbone Diagram. The research is based on an in-depth analysis of documented manufacturing practices, dimensional variability, material behavior, and assembly conditions commonly encountered in automotive production. The findings indicate that noise generation is primarily driven by inconsistent dimensional gaps resulting from process variability rather than design deficiencies alone. Why-Why Analysis reveals that inadequate fixture maintenance, inconsistent adherence to standard operating procedures, and limited sensitivity in quality control systems represent the most dominant root causes. The Fishbone Diagram further demonstrates how human factors, equipment condition, material characteristics, measurement limitations, assembly methods, and environmental conditions interact to amplify noise risks. By combining both analytical approaches, the study provides a comprehensive understanding of the mechanisms behind instrument panel noise and highlights the importance of holistic process control and continuous improvement strategies to achieve sustainable NVH performance.

Abstract

Proses produksi heat exchanger terdiri atas serangkaian tahapan yang saling berkaitan dalam menentukan kualitas produk akhir. Salah satu tahapan yang memiliki peran paling penting adalah proses brazing. Apabila terjadi kegagalan pada proses ini, maka dapat menyebabkan penurunan kualitas produk, meningkatnya jumlah scrap, serta berkurangnya efisiensi proses produksi. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis defect yang muncul pada proses brazing, menganalisis faktor-faktor yang menjadi penyebab terjadinya defect, menentukan prioritas risiko kegagalan, serta menyusun usulan perbaikan pada proses produksi di PT DIID. Metode yang diterapkan adalah Failure Mode and Effects Analysis (FMEA) untuk menentukan tingkat prioritas risiko melalui perhitungan Risk Priority Number (RPN) berdasarkan nilai Severity, Occurrence, dan Detection. Analisis tersebut didukung oleh penggunaan Fishbone Diagram dengan pendekatan 6M yang meliputi (Man, Machine, Method, Material, Measurement, dan Environment) guna mengidentifikasi akar penyebab terjadinya defect. Data penelitian diperoleh melalui observasi langsung, wawancara dengan pihak terkait, serta dokumentasi perusahaan selama periode Januari-Maret 2026. Hasil penelitian menunjukkan bahwa pin hole merupakan jenis defect yang paling dominan dengan persentase sebesar (64,20% dari total defect) yang ditemukan. Selain itu, hasil analisis FMEA menunjukkan bahwa failure mode berupa “ketidakstabilan temperatur torch” memiliki nilai RPN tertinggi, yaitu sebesar (432) sehingga menjadi prioritas utama untuk dilakukan perbaikan. Usulan perbaikan difokuskan pada pengendalian kebersihan material, pengaturan kestabilan temperatur proses, standarisasi pelaksanaan SOP, serta peningkatan kompetensi operator melalui pelatihan. Penerapan rekomendasi tersebut diharapkan mampu menekan jumlah defect, meningkatkan kualitas produk, serta mendukung peningkatan efisiensi proses produksi pada Line Assembly Heat Exchanger di PT DIID
