Abstract

CV Lampung Aspalindo merupakan suatu badan usaha yang berjalan pada bidang industri manufaktur. Badan usaha ini memproduksi produk drum besi khususnya untuk produk aspal dalam drum dari produk setengah jadi hingga produk yang dapat dijual. Permasalahan perusahaan saat ini ialah belum mengkhususkan perhatiannya kepada kondisi lingkungan kerja, dan tidak ada divisi/sub-divisi yang dikhususkan untuk masalah tersebut. Masalah tempat kerja yang didapati antara lain tidak terdapatnya marker line di daerah pengerjaan produksi seperti area bahan baku, mesin, dan lain-lain. Hal lain yang ditemukan ialah beberapa barang personal pekerja dan peralatan kerja belum memiliki lokasi yang ditentukan. Pekerja di area produksi masih belum memperhatikan kondisi kebersihan dan tidak ada rotasi jadwal tugas pembersihan. Hasil dari penelitian ini adalah penilaian checklist audit di area produksi yang mendapat nilai sebesar 26% dan masuk kategori buruk, maka peluang penerapan 5S di area produksi CV Lampung Aspalindo sangat perlu untuk memperbaiki lingkungan kerja. Berdasarkan nilai evaluasi sebelum perbaikan didapatkan nilai sebesar 35% dan setelah dilakukan implementasi 5S didapatkan nilai sebesar 77%. Terdapat 11 implementasi yang berhasil dilakukan dan terdapat 6 usulan yang diharapkan dapat diimplementasikan di CV Lampung Aspalindo.

Abstract

The economic growth potential of North Sumatra is globally recognized due to the achievement of sustainable development goals. This research aims to explore the integration of environmental, social, economic, organizational, local culture, government, and financial institution support factors that can improve supply chain performance and sustainability for small and micro industries in North Sumatra. The study uses a mixed-methods approach that involves in-depth interviews and structured questionnaires to examine the central roles of these factors. The findings underscore the importance of environmental considerations in supply chain management, the impact of local cultural traditions on organizational performance, and the need for innovative economic solutions to improve efficiency and traceability by government and financial support. The research also suggests the implementation of comprehensive policies that integrate all aspects of collaboration to achieve the Sustainable Development Goals in North Sumatra, addressing deglobalization and geopolitical crises.

Abstract

Used cooking oil is cooking oil that is no longer suitable for use because it has undergone changes in physical and chemical properties during the frying process. Used cooking oil is a hazardous and toxic waste; consuming it can cause negative impacts on health and disposing of it carelessly can cause environmental pollution. However, public knowledge about the dangers and impacts of used cooking oil is still minimal. A study showed that there are still many people who dispose of used cooking oil on the ground and waterways. Therefore, the activity designed by the PKM team of Universitas Pembangunan Nasional Veteran Jakarta aims to increase public knowledge about the dangers and impacts of used cooking oil and provide solutions to reduce the pollution of used cooking oil waste. This activity was carried out in the Grand Pakis Residence housing complex using socialization and training methods. In this activity, the PKM team invited representatives from the Jalantara foundation as speakers to explain the impact of used cooking oil on the environment and health to the community. Not only that, the community was also given a training on processing used cooking oil into other products as a solution to reduce used cooking oil waste. The result of this activity is that the knowledge of residents about the dangers of used cooking oil for the environment and health has increased by 80.95%. In addition, the residents also know how to reduce used cooking oil by turning it into useful products such as soap.

Abstract

PT XYZ merupakan industri manufaktur yang memproduksi crumb rubber dengan jenis SIR 20. Tahun 2021, perbandingan jumlah persediaan bahan baku dengan hasil produksi memiliki tingkat eror MAPE lebih dari 50% yang mengindikasikan bahwa model yang digunakan tergolong buruk. Selisih antara jumlah persediaan bahan baku dan jumlah produksi berpotensi meningkatkan biaya produksi. Jumlah persediaan bahan baku di atas titik optimal dapat menyebabkan meningkatnya biaya penyimpanan, sedangan jumlah persediaan di bawah titik optimal berpotensi menambah biaya produksi akibat biaya kekurangan. Tujuan penelitian ini adalah memilih model arsitektur Backpropagation dengan nilai MAPE terendah yang selanjutnya digunakan memprediksi jumlah permintaan produk SIR 20 pada tahun 2023. Arsitektur Backpropagation yang digunakan pada penelitian ini adalah (3-9-1-1), (3-10-1-1), (3-11-1-1), (3-11-1-1), dan (3-12-1-1). Variabel input dalam penelitian ini adalah tahun produksi, jumlah hari, dan harga SIR 20. Model Backpropagation (3-11-1-1) merupakan model yang memberikan hasil prediksi dengan eror terendah, yaitu 14,5%. Model tersebut memberi hasil penuruan nilai MAPE sebesar 36,5% dan peningkatan pendapatan berdasarkan selisih antara pembelian bahan baku dan penjual produk sebesar Rp 62.295.269.963,13.
