Abstract

Perkembangan industri di era sekarang menuntut perusahaan agar selalu memperhatikan kualitas setiap produksinya, pengendlian kualitas produksi adalah aspek penting dalam menjamin keberhasilan pada proses produksi. Pt. XYZ merupakan perusahaan yang bergerak dibidang furniture, adapun permasalahan yang dihadapi perusahaan ialah masih sering terjadi kecacatan produk yang dihasilkan dalam proses produksi diantaranya defect komponen renggang, defect ketebalan rangka berbeda. Pembuatan penelitian ini bertujuan untuk menggurangi defect. Metode seven tools digunakan untuk mengidentifikasi penyebab defect pada proses produksi sedangkan metode FMEA digunakan untuk melakukan upaya perbaikan. Dari hasil pengolahan data pada control chart terdapat kecacatan harian yang melebihi batas kendali, maka dari itu perlu dilakukan pengolahan menggunakan fishbone diagram hasil pengolahan didapatkan 8 indikator penyebab dari kedua jenis defect, dari 8 penyebab defect tersebut kemudian menentukan nilai RPN dengan mengalikan nilai severity, occurance dan detection. Pada hasil tersebut didapatkan nilai RPN tertinggi sebesar 252 yaitu indikator tempat penyimpanan bahan baku tergenang air.

Abstract

Small and medium industry engaged in fast food. Currently, the layout of the facilities at the production site is experiencing problems related to the distance of material movement. This study aims to redesign the layout of the facility and make suggestions to the trade business to minimize material movement to make it more comfortable and efficient. The method used in the process of redesigning the layout of the facility at UD. ARSHAINDO is to use the FTC (From To Chart) method. From To Chart is a method that can help to solve problems then described in more detail by going through several stages of completion to the maximum point. The results obtained from the From To Chart calculation with a total distance between departments of 36 meters (proposed layout), while the distance applied to UD. ARSHAINDO currently has a distance between departments of 56 meters (initial layout), therefore the proposed layout design has minimized the material transfer distance between departments by 20 meters so that it can produce a maximum layout and the production process is more efficient in terms of the distance between previous departments

Abstract

Batu bara merupakan bahan bakar yang tidak dapat diperbarui dan masih mendominasi peran sebagai bahan bakar utama Pembangkit Listrik di Indonesia. Sumber energi yang dapat diperbarui seperti matahari mulai dikembangkan sebagai alternatif. PLTS merupakan sistem yang mampu mengkonversi energi radiasi cahaya matahari menjadi listrik menggunakan modul semikonduktor fotovoltaik. Gedung Teknik Politeknik Negeri Jember memiliki PLTS di atapnya yang terdiri dari 4 kWp PLTS off-grid dan 6 kWp PLTS on-grid. Namun, hanya sistem off-grid sebesar 4 kWp saja yang sudah dioperasikan. Pada penelitian ini dilakukan studi evaluasi pada PLTS off-grid terkait berdasarkan Panduan Studi Kelayakan PLTS dan IEC 61724. Pengujian dilakukan selama 3 hari mulai pukul 09.00 – 14.30 dengan interval 30 menit menggunakan 2 lampu halogen dengan total daya 800 W. Berdasarkan penelitian yang telah dilakukan, PLTS memiliki nilai efisiensi PV 43 %, inverter 92 %, SCC 95 %, dan rasio performansi 44%. Selama proses pengujian tidak didapati kendala yang fatal dan kondisi fisik komponen secara keseluruhan baik. Optimasi yang dapat dilakukan adalah maintenance seperti cleaning secara berkala, penambahan perangkat monitoring seperti pyranometer yang terintegrasi dengan sistem PLTS untuk memudahkan pemantauan sistem. Untuk meningkatkan efisiensi modul surya, penambahan alat pembuang panas pada modul atau sistem pendinginan dapat dilakukan.

Abstract

Occupational Safety and Health (OSH) plays a critical role in maintaining safe and sustainable production, particularly in small-scale agro-industrial operations such as coffee processing. This study applies the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) framework to evaluate workplace hazards at Kopi Lanange Jagad, a micro-scale coffee producer in Malang Regency, Indonesia. Field observations and structured interviews were conducted to identify potential hazards across four production stages roasting, grinding, sieving, and packaging. Quantitative measurements were also taken, including ambient temperature, noise level, and airborne dust concentration, to provide empirical data for risk evaluation. The findings identified a total of 12 hazards, classified into three risk categories: high (25%), moderate (50%), and low (25%). The roasting process exhibited the highest risk score (R = 18.4), with average workplace temperatures reaching 85°C–120°C, significantly exceeding the national occupational limit of 30°C for moderate workloads (Permenaker No. 5/2018). The grinding stage also presented considerable hazards, with airborne dust concentrations averaging 2.4 mg/m³, approaching the Ministry of Manpower’s threshold limit value (TLV) of 3 mg/m³. Manual packaging was associated with ergonomic strain, where workers lifted 15–20 kg sacks repeatedly, leading to potential musculoskeletal disorders. Risk evaluation revealed that existing control measures such as natural ventilation and sporadic use of personal protective equipment (PPE) were insufficient to ensure worker safety. To reduce these hazards, the study recommends implementing engineering controls such as local exhaust ventilation and machine insulation, combined with administrative measures including job rotation, scheduled rest breaks, and regular safety training. Ensuring consistent PPE use especially heat-resistant gloves, dust masks, and ear protection can further mitigate residual risks. Overall, the application of the HIRARC framework at Kopi Lanange Jagad demonstrates its effectiveness as a low-cost and practical tool for identifying, prioritizing, and managing occupational hazards in small-scale coffee industries. Implementation of the proposed control strategies is projected to reduce total workplace risk by 35–40%, improving both worker well-being and operational productivity.
