Abstract

This 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.

Abstract

This 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.

Abstract

Postur 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.
