Abstract

Perkembangan mode dari waktu ke waktu membuat kebutuhan sandang terus mengalami peningkatan, perusahaan kurang mampu mengelola sumber daya yang digunakan tidak dapat memenuhi kebutuhan konsumen dengan tepat dan cepat, masalah ini sering kali terjadi di PT MNO banyaknya kelebihan produk di Department Viscose (selulosa), sehingga jumlah produksi melebihi permintaan, mengakibatkan sistem perencanaan kapasitas produksi di perusahaan belum optimal, tujuan penelitian ini untuk mengetahui perbaikan apa yang harus dilakukan untuk memperbaiki perencanaan kapasitas produksi di PT MNO. Berdasarkan analisa menggunakan metode Rough Cut Capacity Planning (RCCP), maka perusahaan memerlukan adanya penambahan tenaga kerja. Karena pada PT MNO proses produksinya kontinyu dan perusahaan menggunakan 5 hari kerja dengan 2 shift per hari, sehingga pada proses produk perlu dilakukan jam lembur lagi dan penambahan tenaga kerja.
MENINGKATKAN EFISIENSI BIAYA PRODUKSI DENGAN MENGGUNAKAN METODE JUST IN TIME PADA HOME INDUSTRY KERUPUK RAIHAN PURWAKARTA Sagita, Laela; Iskandar, Hendi; Yudhanegara, Darmawan; Muchtar, Diki

Abstract

Penelitian ini bertujuan untuk mengetahui penerapan metode Just InTime dalam meningkatkan efisiensi biaya produksi pada home industri kerupuk raihan. Pengumpulan data dilakukan dengan wawancara, observasi dan studi dokumentasi. Data yang diolah adalah laporan persediaan tahun 2022. Teknik perhitungan yang digunakan adalah menghitung total biaya produksi berdasarkan kebijakan perusahaan, metode EOQ, dan metode JIT/EOQ, serta menghitung siklus penjadwalan produksi. Berdasarkan hasil perhitungan disimpulkan bahwa kebijakan pengendalian persediaan yang dilakukan perusahaan belum maksimal terlihat dari total biaya produksi yang dikeluarkan sebesar Rp.5.952.274,- dibandingkan dengan metode JIT/EOQ sebesar Rp.1.463.008,-sehingga total biaya yang dihemat sebesar Rp.4.489.226,-

Abstract

Purwakarta Station, as one of the busiest train stations in Indonesia, often experiences passenger congestion, especially during peak hours. Not only does this cause inconvenience to passengers, but it can also pose a safety risk. The purpose of this study is to improve the efficiency and safety of train passenger queues. This research uses Promodel software. The results of this study found that there was no waiting presentation and down presentation. Meanwhile, there is a percentage of delay in the location of entering the counter and exiting the counter. Presentations were blocked by 4.47% and the percentage of counter exit was 52.89%. This means that there is no significant buildup in the simulation of the train ticket purchase queue system at Purwakarta Station).

Abstract

PD.ABC experienced problems with an inefficient production system. This is indicated by the minimum amount of output that can be sent. This becomes a source of problems when there is a large order of dorokdok skin crackers, which cannot be completely filled. Therefore, this research will analyze the factors that become obstacles in the dorokdok skin cracker production system using a system modeling and simulation approach. The conclusion was that in the PD dorokdok skin cracker production system. ABC still lacks workers for the production process. This causes the failure rate in sending dorokdok skin crackers to still exist and losses occur. With 2 operators, the maximum output produced is only 63 pcs/day with costs incurred of Rp. 2,950,000 and the profit obtained is only Rp. 1,260,000 or it could be interpreted that PD.ABC suffered a loss of Rp. 1,690,000. After improvements were made, by adding 3 operators it was seen that the simulation results did not show any failures in the production process flow of dorokdok skin crackers with the maximum output produced being 500 pcs/day, the total costs incurred amounting to IDR 6,850,000 and the profit obtained amounting to IDR 10,000,000 or it could be interpreted as PD.ABC experiencing a profit of IDR 3,150,000. So it can be concluded that the improvements made have been effective by increasing human power thereby increasing PD dorokdok skin cracker production capacity. A B C
