Abstract

PT XYZ merupakan perusahaan bergerak di bidang farmasi dan kosmetik, mempunyai quality policy untuk selalu melakukan continous improvement (Kaizen) bagi kepuasan pelanggan yang maksimal. Tujuan dari penelitian ini adalah untuk meningkatkan produktivitas dan efisiensi kerja pada Lini Pengemasan Sekunder  PT XYZ di salah satu proses printing identitas produk X dengan menggunakan metode analisis PDCA. Hasil IPC berupa data cacat printing identitas produk X sebanyak 7,4% melebihi dari standar cacat yang ditetapkan perusahaan yaitu 5%.  Analisis penyebab cacat dilakukan menggunakan fishbone diagram. Diketahui faktor penyebab cacat yang disebabkan oleh faktor material, berupa batas toleransi area print di desain blok putih terlalu kecil. Selain itu cacat juga disebabkan belum adanya kualifikasi personil, dan metode yang belum jelas. Setelah dilakukan improvement perusahaan dapat menghemat biaya pegawai sebesar Rp 229.288.804 karena adanya pengurangan pegawai dan prosedur yang tepat.Produktivitas, Cacat produk, Kaizen, PDCA, Fishbone.

Abstract

PT XYZ adalah perusahaan yang bergerak di bidangjjmanufaktur. Perusahaan ini memproduksi berbagai jenis komponen yang nantinya akan dirakit pada perusahaan perakitan pesawat terbang, seperti komponen  nonaerospace dan aerospace berpresisintinggi. Berbagai jenis komponen diproduksi dengan bahan baku utama di perusahaan ini yakni aluminium. Perusahaan akan mengalami kerugian apabila terjadi kelebihan atau kekurangan dalam persediaan, hal ini harus menjadi perhatian bagi perusahaan untuk memaksimalkan pengendalian persediaan aluminium. Penelitian ini bertujuan untuk mengoptimumkan persediaan aluminium pada perusahaan dengan mencari metode pengendalian persediaan yang tepat. Penelitian ini menggunakan metode persediaan probabilistik model Q. Mencangkup pengendalian model Q back order dan Q lost sales. Mengikuti pengolahan data, dibanding model persediaan lainnya, model Q lost sales menunjukan solusi paling optimal. Model Q lost sales menunjukan jumlah persediaan pengaman (safety stock) optimal dan biaya total yang paling minimal, yaitu dengan penghematan biaya sebesar Rp. 19.224.832 atau 4,9% dari total biaya model perusahaan dengan tingkat pelayanan sebesar 99,37%.

Abstract

Based on the performance achievements of the Ministry of Environment and Forestry, in 2023 unmanagedwaste amounted to 5,899,371.35 tons/year. The data shows that there is still a waste management process atthe upstream level that is not optimal. The downstream of waste, namely landfills, is an obstacle due toexcess capacity. It was recorded that 38 landfills burned in 2023 in a number of regions in Indonesia. Oneof the landfills that caught fire was the Sarimukti landfill located in Bandung. Before the waste is finallydumped in the landfill, the waste will transit in the TPS. The purpose of this study was to design a layout atthe Widyatama University TPS using the TPS-3R method and SNI 19-2454-2002. Observations andobservations were made in June and July 2023 at Widyatama University TPS to see the condition of wastegeneration and TPS buildings, while the observations made were measurements of the TPS area andidentification of the current layout conditions. The proposed layout design for Widyatama University TPSis divided into 5 places based on the largest waste category, namely: leaf organic waste with a size of 1 x 1.5x 1 m; food waste organic waste with a size of 1 x 1.5 x 1 m; plastic inorganic waste 1.5 x 1.5 x 1 m;cardboard / paper inorganic waste with a size of 1.3 x 1.5 x 1 m; and styrofoam inorganic waste with a sizeof 0.7 x 1.5 x 1 m. At the TPS, a mixed waste outpouring area is also made as a waste bin before sorting,then an organic waste processing area is made which contains an organic waste chopping machine, and acontainer is prepared as a storage area for residual waste.

Abstract

Indonesia’s maritime trade development heavily depends on the effective utilization of its port infrastructure, particularly in Sumatra, which is strategically located along the Malacca Strait and near major ASEAN markets. However, trade and logistics activities remain concentrated in Java, creating regional imbalances and leaving western Indonesian ports underutilized. This study aims to identify the most strategic ports in Sumatra that can serve as international trade hubs by developing a spatially integrated, multi-criteria evaluation framework. Three main criteria, trade volume, global connectivity, and multimodal accessibility, were assessed using the Analytic Hierarchy Process (AHP) based on expert input from port management, logistics, and transport planning specialists. Geographic Information System (GIS)-based proximity analysis was applied to evaluate each port’s access to roads, railways, and industrial centers, producing a Multimodal Connectivity Index integrated into the AHP model. The findings reveal that Boom Baru (Palembang), Belawan (Medan), and Batu Ampar (Batam) rank as the top-performing ports, with final scores of 0.875, 0.855, and 0.800, respectively. These ports exhibit high trade volumes and superior multimodal connectivity, with Boom Baru and Belawan achieving the highest connectivity index (2.67 out of 3.00). In contrast, Pekanbaru and Tanjung Balai Karimun scored lower due to limited infrastructure and weaker integration. The study concludes that incorporating GIS-based spatial analysis into the AHP framework reduces subjectivity in port evaluation and provides a replicable, data-driven tool for regional infrastructure prioritization. This approach contributes a novel composite index and offers strategic insights for developing Sumatra’s role in Indonesia’s maritime trade network.
