AbstrakPerkembangan industri yang berlangsung pesat mengakibatkan terjadinya persaingan yang semakin tinggi antara perusahan dengan perusahaan lainnya dalam memenuhi kebutuhan konsumen. Setiap perusahaan yang bergerak dalam bidang pengadaan barang atau jasa memerlukan persediaan. Penelitian ini dilakukan di Kangean Energy Indonesia Ltd. yaitu perusahaan eksplorasi dan produksi minyak dan gas. Divisi Inventory dan Logistic merupakan divisi yang bernaung di Departemen Supply Chain Management yang fokus dalam menyediakan dan menyimpan barang – barang operasional yang dibutuhkan oleh seluruh bagian perusahaan. Salah satu jenis material yang dikelola yaitu material MRO (Maintenance, Repair, Operations). Dalam material jenis MRO terdapat material Filter yang dipesan oleh KEI. Saat ini, ketersediaan material tersebut sangat sulit dikendalikan karena sering digunakan dan mudah kotor maka material tersebut seringkali mengalami stockout. KEI menerapkan metode Minimum Maximum Level (Min Max) untuk mengendalikan persediaan seluruh material jenis Filter tetapi tidak relevan dengan keadaan perusahaan saat ini, sebab perusahaan sering mengalami overstock maupun stock out pada beberapa material jenis MRO. Penelitian ini bertujuan untuk membandingkan kinerja manajemen persediaan yang digunakan oleh perusahaan dengan metode EOQ (Economic Order Quantity), POQ (Period Order Quantity) dan min max. Dari ketiga metode tersebut, metode EOQ merupakan metode terbaik karena menunjukan penurunan inventory terbesar jika dibandingkan dengan kedua metode lainnya.Kata kunci: Pengendalian persediaan, Metode EOQ, Metode POQ, Metode min max.Abstract[Control Of Filter Material Inventory With Comparison Of Eoq, Poq, And Min – Max Methods (Case Study: Kangean Energy Indonesia Inventory Department, Ltd.)] The development of the industry has resulted in increasingly high competition between companies and other companies in meeting consumer needs. Every company engaged in the procurement of goods or services requires inventory. This research was conducted at Kangean Energy Indonesia Ltd. namely oil and gas exploration and production companies. The Inventory and Logistics Division is a division under the Supply Chain Management Department that focuses on providing and storing operational goods needed by all parts of the company. One type of material that is managed is MRO (Maintenance, Repair, Operations) material. In the MRO type material, there is a filter material ordered by KEI. Currently, the availability of these materials is very difficult to control because they are often used and get dirty easily, so these materials often experience stockout. KEI applies the Minimum Maximum Level (Min Max) method to control the inventory of all Filter type materials but it is not relevant to the current state of the company, because the company often experiences overstock and stock outs on several MRO types of materials. This study aims to compare the performance of inventory management used by companies with the methods of EOQ (Economic Order Quantity), POQ (Period Order Quantity) and min max. Of the three methods, the EOQ method is the best method because it shows the largest decrease in inventory when compared to the other two methods.Keywords: Inventory control, EOQ method, POQ method, min max method.

AbstrakPT Iskandar Indah Printing Textile merupakan perusahaan manufacture textile yang memproduksi material benang menjadi kain mentah (kain grey) dan batik printing. Aktivitas perusahaan ini masih mengandalkan sumber daya manusia salah satunya pada unit warping. Unit warping yaitu bagian persiapan pada produksi yang membutuhkan energi lebih dalam pekerjaannya yang dapat menciptakan beban kerja. Pekerja unit warping mendapatkan target produksi yang diberikan untuk setiap tim dapat mereka capai. Terdapat kejadian gulungan benang beberapa beam kontruksi pada unit warping belum selesai sehingga menghambat pekerjaan pada unit sizing. Akibatnya unit sizing menganggur sehingga mengurangi produktivitas dan menyebabkan keterlambatan pesanan. Tujuan penelitian ini untuk mengidentifikasi penyebab faktor-faktor yang dapat mempengaruhi beban kerja mental pekerja unit warping dengan menggunakan NASA-TLX. Metode NASA-TLX berisi kuesioner tentang kebutuhan pengukuran subjektif yang lebih mudah tetapi lebih sensitif pada pengukuran beban kerja (Hancock, 1988). Metode NASA-TLX lebih baik daripada metode lainnya karena pengukuran dilakukan dengan mengukur enam dimensi ukuran beban kerja mental yaitu kebutuhan mental, kebutuhan fisik, kebutuhan waktu, performansi, tingkat usaha dan tingkat frustasi (Okitasari dan Pujotomo, 2016). Berdasarkan masalah tersebut peneliti memperoleh hasil yang menunjukan bahwa dalam unit warping terdapat 10 pekerja memiliki beban kerja mental sedang dan 4 pekerja memiliki beban kerja mental berat. Dalam penelitian ini terdapat rekomendasi perbaikan yang diusulkan namun usulan perbaikan tersebut belum dilakukan implementasi.Kata Kunci: NASA-TLX, Beban Kerja, Mental Workload, Kebutuhan Mental, Kebutuhan FisikAbstractPT Iskandar Indah Printing Textile is a textile manufacturing company that produces yarn material into raw cloth (gray cloth) and batik printing. The company's activities still rely on human resources, one of which is in the warping unit. The warping unit is a preparatory part of production that requires more energy in its work which can create workload. Warping unit workers get production targets given to each team that they can achieve. There is an incident of several beam construction yarn rolls in the warping unit that have not been completed so that it hampers work on the sizing unit. As a result, the sizing unit is idle, reducing productivity and causing delays in orders. The purpose of this study is to identify the causes of factors that can affect the mental workload of warping unit workers using NASATLX. The NASA-TLX method contains a questionnaire on subjective measurement needs that is easier but more sensitive to workload measurement (Hancock, 1988). The NASA-TLX method is better than other methods because measurements are made by measuring six dimensions of mental workload measures, namely mental needs, physical needs, time needs, performance, level of effort and level of frustration (Okitasari & Pujotomo, 2016). Based on this problem, the researcher obtained results that showed that in the warping unit, 10 workers had a moderate mental workload and 4 workers had a heavy mental workload. In this study, there are recommendations for improvements proposed but the proposed improvements have not been implemented.Keywords: NASA-TLX, Workload, Mental Workload, Mental Needs, Physical Need

AbstrakSebagai perusahaan yang bergerak di bidang manufaktur, PT Pindad (Persero) tentunya perlu memperhatikan aspek efisiensi mulai dari proses produksi hingga produk jadi dapat sampai di tangan konsumen, tidak terkecuali pada produk Shoulder For E-Clip. Berdasarkan studi dan observasi yang dilakukan, ditemukan tujuh jenis waste yang terjadi di sepanjang proses produksi Shoulder For E-Clip. Identifikasi dan pemeringkatan waste dilakukan dengan menggunakan metode Waste Assessment Model (WAM). Hasil pengolahan data menunjukkan bahwa waste paling kritis ditemukan pada jenis overproduction dengan persentase 20.71%, diikuti defects dengan persentase 18.77%, serta inventory dengan persentase 15.71%. Sub-waste dari ketiga waste paling kritis dicari menggunakan analisis 5-Whys sebagai bahan pertimbangan untuk mencari akar permasalahan pada metode Failure Mode and Effect Analysis (FMEA). Hasil analisis pada FMEA menunjukkan bahwa Risk Priority Number (RPN) tertinggi ditemukan pada mode kegagalan breakdown mesin akibat produksi yang melebihi kapasitas, produk tidak sesuai spesifikasi akibat proses penuangan yang hanya mengandalkan feeling operator, serta penumpukan bahan mentah akibat kehabisan bahan bakar. Usulan perbaikan yang diberikan berupa pengadaan training berkala tentang maintenance mesin kepada operator, melakukan reverse engineering pada mesin sambil meningkatkan pengawasan, serta melakukan evaluasi atau pergantian pada vendor penyedia bahan bakar.Kata kunci: 5-Whys; FMEA; Proses produksi; RPN; Shoulder for E-Clip; Waste Assessment ModelAbstractAs a manufacturing company, PT Pindad (Persero) needs to pay attention to production process efficiency until the finished products can reach consumers, including Shoulder For E-Clip products. Based on studies and observations conducted, seven types of waste were found that occurred throughout the Shoulder For E-Clip production process. Waste identification and ranking is done using the Waste Assessment Model (WAM) method. The data processing results showed that the most critical wastes were Overproduction with a percentage of 20.71%, followed by Defects with a percentage of 18.77%, and Inventory with a percentage of 15.71%. Sub-waste of the three most critical wastes is sought using 5-Whys analysis as a consideration to find the root cause in the Failure Mode and Effect Analysis (FMEA) method. FMEA results showed that the highest Risk Priority Number (RPN) was found in the engine breakdown failure mode due to production that exceeded capacity, the product did not meet specifications due to the inaccurate pouring process, as well as the cummulation of raw materials due to fuel shortage. The proposed improvements provided are conducting periodic training on engine maintenance for operators, reverse engineering on the engine while increasing supervision, and evaluating or replacing fuel suppliers. Keywords: 5-Whys; FMEA; Production process; RPN; Shoulder for E-Clip; Waste Assessment Model
