Abstract

This study  aims to design the planning of sausage raw materials at PT. RF using the Material Requirement Planning (MRP) method. Demand forecasting was carried out using the trend decomposition method for the period of Mei 2025 to April 2026. The forecasting results were used to prepare the Master Production Schedule (MPS) and to calculate raw material needs. The analysis focused on three main raw materials: chicken meat, ice, and seasoning. The results show that the MRP method can accurately determine the quantity and timing of raw material orders according to production needs. The application of this method helps the company avoid shortages or excess inventory and improves the efficiency of procurement and storage processes.

Abstract

PT. Pupuk Kujang Cikampek, as a national fertilizer producer, currently operates two NPK plants (NPK 1 and NPK 2). In 2024, the company is projected to face a demand of 165,007 tons of NPK fertilizer. If this demand remains unmet, it may lead to unfulfilled customer needs and lost market opportunities, which could negatively impact the company. Therefore, a plan to build a third NPK plant (NPK 3) is deemed necessary to meet future market demands. This study aims to design a facility layout for the NPK 3 plant using the Systematic Layout Planning (SLP) method in order to improve material flow efficiency, minimize material handling costs, and optimize space utilization. The results show that the required floor area is 1,543.48 m² for the raw material warehouse, 785 m² for the finished goods warehouse, and 465.57 m² for the production area. The proposed plant layout is designed in a linear configuration that follows the production process flow, which significantly reduces material handling costs compared to the initial layout.

Abstract

Penelitian ini mengkaji efisiensi biaya logistik menggunakan model linear programming berbasis optimasi multi-kendala dengan mempertimbangkan kapasitas angkut dan biaya inventori. PT. Pupuk Kujang menghadapi tingginya frekuensi pengiriman bahan baku NPK yang dikirim dari gudang asal ke gudang transit. Saat ini PT. Pupuk Kujang masih menggunakan metode lama yang hanya mempertimbangkan dump truck kapasitas 5 ton yang berdampak pada meningkatnya biaya operasional. Dalam penelitian ini, penentuan kapasitas dump truck dilakukan dengan memilih antara 2 jenis kapasitas, yaitu dump truck kapasitas 5 ton dengan 25 ton. Temuan ini menunjukkan bahwa penerapan model linear programming mampu meningkatkan efisiensi operasional logistik hingga 62%, memperkuat pengambilan keputusan berbasis data dalam manajemen transportasi industri pupuk. Hal ini berpengaruh terhadap rendahnya frekuensi pengiriman bahan baku.

Abstract

This study evaluates the technical and economic feasibility of establishing a 2 GWp solar-grade silicon wafer manufacturing facility in Batam Industrial Area, Indonesia. The proposed plant utilises Chinese-manufactured equipment for key processes, including 40 CZ Puller units, 20 Multi-Wire Saw units, and 15 CMP systems, with polysilicon as the primary raw material. A comprehensive analysis incorporating technical, financial, operational, and market aspects demonstrates project viability with an IRR of 18-20% and a payback period of 5-6 years. The total investment of USD 250 million encompasses equipment, infrastructure, and working capital. Results indicate favourable technical feasibility with established Chinese equipment manufacturers meeting international quality standards. Financial analysis shows strong potential returns, supported by growing regional solar panel demand and Batam's strategic advantages. Key risks identified include polysilicon price volatility, technological obsolescence, and market competition, with structured mitigation strategies proposed.

Abstract

Industri Rumahan Krapel Craft merupakan salah satu industri rumahan yang bergerak di bidang kerjainan keramik di Plered, Purwakarta. Ketidakstabilan permintaan, menyebabkan Industri Rumahan Krapel Craft mengalami kesulitan untuk menentukan jumlah Pot Keramik yang harus diproduksi. Hal ini juga menyebabkan Industri Rumahan Krapel Craft sering mengalami kekurangan dalam memenuhi permintaan Pot Keramik. Dampak dari terjadinya hal tersebut yaitu besarnya biaya yang harus dikeluarkan oleh Industri Rumahan Krapel Craft untuk melakukan lembur. Jika tidak, konsumen beresiko akan tidak lagi berlangganan Pot di sana. Oleh karena itu, perlu adanya sebuah perencanaan produksi sebagai upaya yang dilakukan agar Industri Rumahan Krapel Craft dapat menentukan jumlah Pot yang harus diproduksi serta berapa jumlah tenaga kerja yang diperlukan untuk dapat memenuhi permintaan konsumen. Pengolahan data dimulai dengan melakukan permalan terhadap data permintaan selama 12 bulan. Hasil peramalan terbaik dipilih berdasarkan pada nilai error terkecil. Data hasil peramalan digunakan untuk melakukan perencanaan produksi. Metode heuristik dengan strategi konstan digunakan untuk melakukan perencanaan produksi Pot Keramik bulan Oktober 2021 sampai dengan September 2022. Hasil perencanaan produksi memperlihatkan bahwa jumlah produksi Pot Keramik bulan Oktober 2021 sampai dengan September 2022 secara berurutan yaitu 2033, 1883, 2033, 1958, 1851, 2033, 1958, 1958, 1958, 2033, 1958 dan 1958, dengan biaya produksi Rp 630.725.564

Abstract

CV. PQR is a company operating in the printing sector. The main printing produced at the company is labels for vegetable products. When producing labels, the company always strives to produce quality products that reach consumers on time. In order for the production process to run, good production scheduling is needed. This research aims to schedule label production on CV. PQR. The label production scheduling method used is Palmer. The results of production scheduling calculations using the Palmer method have a job sequence of 10-9-8-7-6-4-5-3-2-1 and produce a makespan value of 248740 seconds or 69.0944 hours and require 8.6368 days to complete everything. jobs. There is a time difference between the company's initial condition production scheduling and production scheduling using the Palmer method, namely 13160 seconds or 3.6556 hours or 0.45695 days. So the Palmer method can minimize delivery delays
