No full textIdentifikasi dan Evaluasi Risiko Kegagalan Kualitas Crude Palm Oil dengan Metode FMEA: Studi Kasus di PKS Tanjung Seumatoh
No full textThis study aims to analyze the factors influencing the quality of Crude Palm Oil (CPO) at the Tanjung Seumatoh Palm Oil Mill (PKS) using the Failure Mode and Effect Analysis (FMEA) method. FMEA was employed to identify and evaluate potential failure risks that could cause the CPO quality to fall outside the company’s established standards. Based on the Risk Priority Number (RPN) calculations, the factor with the highest RPN was machine (RPN = 180), followed by raw material and work method, both with an RPN of 144. Other factors, such as environment, operator, and maintenance, did not show significant RPN values (below 120). The results indicate that poorly maintained machinery, suboptimal raw materials, and non-standard work methods are the primary causes of reduced CPO quality. To improve CPO quality, it is recommended that the company perform regular machine maintenance and modernization, ensure optimal raw material maturity through strict sorting, and enhance training and supervision of work methods. Implementing these corrective measures is expected to improve product quality and reduce the risk of failures in the production process
EVALUASI POSTUR KERJA PADA STASIUN LOADING RAMP DI PTPN UNIT TANJUNG SEUMANTOH MENGGUNAKAN METODE REBA (RAPID ENTIRE BODY ASSESSMENT)
No full textPostur kerja yang tidak ergonomis dapat meningkatkan risiko kelelahan dan cedera pada pekerja, terutama di stasiun loading ramp saat pengambilan Tandan Buah Sawit (TBS). Penelitian ini bertujuan untuk menganalisis tingkat risiko postur kerja menggunakan metode Rapid Entire Body Assessment (REBA) di PTPN IV PKS Tanjung Seumantoh. Berdasarkan hasil analisis, skor REBA yang diperoleh adalah 7, yang masuk dalam kategori risiko ‘sedang’ dan membutuhkan perbaikan. Penilaian dilakukan terhadap enam variabel utama, yaitu leher, batang tubuh, kaki, lengan atas, lengan bawah, dan pergelangan tangan. Hasil evaluasi menunjukkan bahwa seluruh variabel memberikan kontribusi terhadap tingginya skor REBA. Untuk mengurangi risiko kelelahan dan mencapai skor 0, diperlukan perbaikan dalam aktivitas kerja di loading ramp, termasuk penyesuaian postur kerja, desain alat kerja, dan pelatihan ergonomi bagi pekerja. Penelitian ini memberikan rekomendasi praktis untuk meningkatkan kesehatan dan keselamatan kerja, serta efisiensi operasional perusahaan.
 
ANALISIS PENGENDALIAN PERSEDIAAN BAHAN BAKU UNTUK MENGOPTIMALKAN PENGELOLAAN TANDAN BUAH SEGAR (TBS) MENGGUNAKAN METODE ECONOMIC ORDER QUANTITY (EOQ) PADA PTPN IV PKS TANJUNG SEUMANTOH
No full textThis study aims to optimize the amount of raw material inventory at PTPN IV Regional 6 PKS Tanjung Seumantoh using the Economic Order Quantity (EOQ) method. Based on raw material inventory data during the period January-October 2024, it is known that the initial raw material inventory of 667 tons is far from optimal. Through analysis using the EOQ method, it was found that the optimal amount of raw material inventory is 903 tons. The implementation of this method is expected to increase the efficiency of raw material inventory management by reducing the risk of shortages or excess stock, as well as reducing related operational costs. Thus, the company can improve operational performance and the sustainability of its production process
Analisis Potensi Bahaya pada Stasiun Sterilizer di PTPN IV PKS Tanjung Seumantoh Menggunakan Metode Job Safety Analysis (JSA)
No full textThis study aims to identify potential hazards at the sterilizer station in PTPN IV using the Job Safety Analysis (JSA) method. This method is applied to identify potential hazards in each work process at the sterilizer station. The analysis results show that the highest hazard potential occurs in two processes: during the sterilization of Fresh Fruit Bunches (FFB) with a risk score of 5, and when opening the sterilizer door after sterilization is complete, with a risk score of 15. These two processes require further control measures. Additionally, analysis was carried out on six other processes, including floor cleaning in the sterilizer area, pulling the cart using a capstan, adding and releasing steam at peak 1, peak 2, and peak 3 during sterilization, and attaching the capstan rope to the hook at the end of the cart. Therefore, optimal control efforts are needed during the FFB sterilization process and the opening of the sterilizer door to minimize hazard risks to a low level
Rancangan Aliran Proses dalam Upaya Meminimumkan Proses Non-Value Added melalui Value Stream Mapping pada UD Usaha Rezeki Prabot
No full textThe flow of process is a sequence of jobs or activities performed in producing goods and services. UD. Usaha Rezeki Prabot, a small-to-medium enterprise (SME) in furniture manufacturing, consistently faces a critical operational challenge: despite stable customer demand (853 units/year of panel door type 7), only 750 units (88%) are delivered on time, resulting in a 12% delay rate. This gap is not caused by insufficient labor or machinery, but by a fragmented production system riddled with non-value-added (NVA) activities particularly repetitive machine setup, excessive material handling, redundant measurements, and long waiting times that inflate lead time to 176.91 minutes per unit. Value Stream Mapping (VSM) is applied as a lean tool to visualize the entire material and information flow, identify dominant wastes (waiting, over-processing, and unnecessary motion), and redesign the workflow. Through the implementation of future-state mapping by grouping components with identical profiles into batch processing and eliminating redundant inspections the NVA time was reduced from 79.95 minutes (45.19%) to 16.07 minutes (15.93%), cutting total lead time by 43%. This study demonstrates that for SMEs like UD. Usaha Rezeki Prabot, sustainable productivity gains come not from capital investment, but from restructuring workflow based on frontline insights to eliminate systemic waste embedded in daily routines. The purpose of this mapping is to identify all types of waste along the Value Stream and to take a move in an attempt to eliminate the waste. The flow of process design with Value Stream Mapping approach enables the company to be able to minimize the non value added activities and to shorten the time taken in the process of making doors and to increase the productivity. The purpose of this Motion and Time study was to do a direct observation about time and movement of someone who is working. UD Rezki Prabot uses the VSM (Value Stream Mapping) to minimize the non value added process and to propose a design to improve the flow of process. The result of this study showed that the time of non value added activities decreased from 176.91 minutes to 100.9 minutes. The non value added activities decreased from 45.19% to 15.93% due to the decrease of non value added activities by sequencing the work activities that the machine does not need to be set up repeatedly
