The definition and function of inventory management reveal the importance of modern industry in formulating policies that regulate the supply of raw materials, semi-finished products, and finished products. Unfortunately, most companies fail to consider the characteristics of their raw materials when determining inventory strategies. Raw materials that are perishable are those that consider their service life and storage time. Inventory management plays a crucial role in supply chain management, especially for perishable raw materials, such as food products. PT X, a food business in Padang, experienced difficulty in meeting the demand for rendang products due to a lack of raw materials. Therefore, this study aims to develop an inventory management model that takes into account the perishable raw materials' expiration time. The model development consists of three stages: model development design, inventory model formulation, and model testing. The proposed model resulted in a storage time interval of five days and an optimal order quantity of 34 kg of meat with a safety stock of 14 kg. Implementing this model led to lower total inventory costs for PT X than the actual conditions of the company. The total inventory cost obtained using this model is Rp279,797,822. This study emphasizes the importance of considering the characteristics of raw materials in determining inventory strategies to optimize inventory management effectively and efficiently. The study's findings can serve as a reference for other food businesses encountering similar inventory management challenges in the perishable food industry.

PT HMG is a manufacturing company that uses injection moulding machines to produce plastic components for the electronics, automotive and engineering industries. The problems found at PT HMG are that the finished goods are not placed in an orderly manner or that the goods are not neatly arranged. The placement of these goods is still mixed with goods that have run out, so the process of moving goods is not optimal and the risk of picking inappropriate goods is higher. This has an impact on delivery errors and the sub-optimal process of moving goods can cause delays in delivery to the customer. Dedicated storage is a layout design method for storing goods where the storage location is fixed. This method uses throughput as areference when positioning goods so that goods with a high flow of movement are prioritised to minimise the time it takes to move goods to I/O points. The difference in the total distance to the I/O point for the proposed layout is 17,809 metres, or 9% of the previous layout. With this layout improvement, the company is able to reduce the waste caused by material handling activities in the finished goods warehouse.

Perencanaan produksi merupakan suatu kegiatan yang sangat penting dan diperlukan dalam suatu perusahaan. Perencanaan produksi dapat dimulai dengan peramalan permintaan konsumen yang akan menjadi patokan dalam menentukan jumlah barang yang akan diproduksi. Bagian produksi tiang besi merupakan bagian yang sangat penting pada PT XYZ karena tiang besi merupakan produksi tertua yang masih beroperasi dan menghasilkan keuntungan terbesar bagi perusahaan. Permintaan pasar terhadap tiang besi tidaklah merata disetiap bulannya melainkan cendrung berpola musiman. Hal ini menyebabkan perencanaan produksi yang dilakukan oleh pihak perusahaan seringkali tidak tepat sehingga pemanfaatan sumber daya tidak merata disetiap periodenya. Oleh sebab itu perlu dilakukan penelitian agar dapat merencanakan produksi yang tepat untuk pola permintaan musiman. Berdasarkan hasil penelitian peramalan dilakukan dengan menggunakan metode konstan karena memiliki error terkecil. Sedangkan Perencanaan produksi agregat yang terpilih yaitu level strategy dengan total biaya produksi sebesar Rp. 3.644.729.500,-. Berdasarkan hasil perencanaan produksi agregat dan disagregasi didapatkan jadwal induk produksi untuk setiap jenis tiang per periode dengan jumlah produksi terbanyak yaitu jenis tiang 11-200.

The burgeoning industrial sector in Indonesia has intensified competition among businesses vying for market share. The furniture industry is a prime example of this dynamic landscape. To expand their market reach, companies must demonstrate their ability to fulfill every consumer demand. Failure to meet these expectations will prompt consumers to seek alternatives. One crucial factor in meeting consumer demands is product availability, which is directly influenced by the availability of raw materials within the company. CV XYZ Furniture, a furniture company based in Padang City, exemplifies this challenge. The company produces a diverse range of furniture, primarily utilizing rattan as its raw material. However, CV XYZ Furniture currently lacks a structured inventory planning method for raw materials, resulting in excess inventory for each period. To address this issue, this research aims to establish an optimized inventory planning strategy for raw materials used in furniture production at CV XYZ Furniture. The continuous review system method serves as the foundation for this endeavor. The research outcomes encompass the determination of optimal demand quantity, reorder point, and safety stock. The implementation of the continuous review system model yielded a significant reduction in total inventory costs, amounting to Rp8,625,594 or 2.03%. It can be proven that the continuous review system model is suitable for calculating raw material inventory at CV XYZ Furniture for raw material planning in the following years.

The concept of halal logistics is getting more attention, especially in the field of distribution and transportation, in line with the increasing demand for halal products in the global market. This study aims to determine the development of the implementation of halal logistics in courier companies in Indonesia using the method of review and literature study. Currently, there are technologies such as the Internet of Things (IoT) and blockchain to help in halal logistics tracking and traceability systems, which can open up opportunities for further innovation in the logistics sector. In Indonesia, there is only one courier company that already has halal certification. However, in its implementation, of course, there are still many problems and challenges faced. One of the biggest challenges is the lack of understanding of halal logistics concepts and standards among courier companies and industry players. Many courier companies do not fully understand halal requirements, both in terms of storage, transportation, and product handling. With a commitment to meeting halal standards and using the right technology, courier companies in Indonesia have a great opportunity to play a more strategic role in supporting halal supply chains domestically and around the world.

This research was conducted to plan material needs and control the production capacity of bracket chambers at an automotive component company. The problems found were company excessively procures raw materials and unbalanced machine capacity in producing bracket chamber products. This research uses stages of the material requirements planning method, including calculating Rough Cut Capacity Planning (RCCP), Material Requirement Planning (MRP), and Capacity Requirement Planning (CRP). Implementing a MRP system enables organisations to accurately ascertain the specific kind, quantity, and timing of materials required for the production process. At the RCCP stage, capacity calculations are carried out on the CNC machine, press 1 and press 2 to find out whether the capacity of each machine can meet the company's MPS. MRP calculations are carried out to determine the optimal raw material ordering schedule using three lot sizing methods, namely Lot For Lot, Economic Order Quantity, and Period Order Quantity. At the CRP stage, each machine's capacity availability report will be made to meet bracket chamber production needs. The results of this research using RCCP and CRP analysis show that press 1 and press 2 have an unbalanced load between availability and actual demand, so it is recommended that these machines can also be used for other production so that the machines are not idle. Material requirements planning should use the Lot For Lot technique because it produces the minimum total inventory costs, namely IDR 12,710,751, with a material ordering frequency of 12 times in 1 year.

Inadequate or delayed supply of raw materials or components needed for production can lead to line stoppages. Reducing the frequency and duration of line stoppages is crucial for maintaining efficiency and meeting production targets. It can happen due to logistics problemsThis research was conducted in the logistics department of an automotive component company. One of the causes is the procurement of tooling, which needs to be improved for production needs. The tooling factor is part of the logistics scope and is the highest factor causing lost opportunities and line stoppages. To minimize the impact of line production stoppages, manufacturers often implement strategies like implementing a minimum stock of insert components. The problem-solving methodology includes a five whys analysis, conducting a Pareto diagram, determining the service level of the stock level, and calculating the maximum-minimum stock level. Based on the result, 17 types of inserts must apply stock levels to avoid stock shortages.
