This research investigates the application of the Economic Order Quantity (EOQ) method to improve drug inventory management in a primary hospital pharmacy, with a particular focus on reducing storage costs. A descriptive quantitative approach was applied using secondary data from January to December 2024, covering annual demand, purchase price, ordering cost, and holding cost. The analysis concentrated on fast-moving vital essential and moderate vital drugs that are critical for sustaining patient treatment. The study revealed inefficiencies in the hospital's procurement practices, with some medicines simultaneously facing overstock and stockout risks, indicating weak planning. EOQ calculations provided alternative procurement quantities that were smaller but more frequent, resulting in lower storage costs and better stock control. Simulation outcomes demonstrated notable cost savings, particularly for Flamicort, Diazepam, and Ventolin. These findings emphasize the value of integrating EOQ into hospital pharmaceutical logistics to reduce financial losses, strengthen supply chain efficiency, and ensure the continuous availability of essential medicines in primary hospital settings.

The purchase of secondhand goods, known as thrifting, involves acquiring and reselling pre-owned clothing at low cost. Originating from Western practices during the Great Depression in the United States, this activity is no longer solely about financial considerations it is also an effort to protect the ecosystem by reducing fashion waste and addressing the adverse impacts of fast fashion, such as pollution and unethical labor practices. In Indonesia, thrifting has expanded rapidly since the 2010s, supported by the creative industry, online access, and platforms like Shopee and Tokopedia. It contributes 10% to the nation’s creative economy (BPS 2022), with export value reaching Rp 100 trillion. This phenomenon has gained traction among young generations such as millennials and Gen Z, often aligning with local cultural traditions. In Maumere, a small city in East Nusa Tenggara with limited access to international fashion, thrifting has emerged as a primary option for students. Stores offer t-shirts, blouses, and dresses priced between Rp 20,000 and Rp 50,000, which suits their modest financial circumstances. Jeanette’s (Aunt Cindy’s) business focuses on top garments like crop t-shirts and crop blouses, leveraging online marketing through TikTok, Instagram, and Facebook to compensate for the store’s less-than-ideal location. This study employs a qualitative approach with direct interviews with Jeanette, using SWOT analysis for evaluation. Strengths: Affordable pricing and alignment with current fashion trends enhance customer loyalty. Weaknesses: Delayed inventory arrivals, "PHP" behavior (holding items without purchase), ineffective management, and limited product options. Opportunities: Adoption of digital technology and fashion trends. Challenges: Domestic competitors and low-priced imported goods. This study provides strategic guidance for small businesses in remote areas to adapt to the digital era.

In the fast-moving fashion retail industry, supply chain efficiency is a key factor in operational success. Heybeb Factory Outlet, as one of the retail business actors, faces challenges in managing the flow of goods from upstream to downstream, particularly in balancing demand between offline (physical stores) and online (e-commerce/marketplace) channels. This proposal aims to design and analyze the logistics workflow starting from goods ordering (restocking) from the central warehouse, the goods receiving process, rigorous Quality Control (QC) procedures, storage in a dedicated transit warehouse, and the stock distribution mechanism (stock split) for the two sales channels. The main issues identified include the risk of overselling in one channel while stock accumulation occurs in another, as well as the potential for defective items to pass through due to an unstructured QC process. This study employs a descriptive qualitative approach by mapping out an ideal Standard Operating Procedure (SOP). The expected outcome is the development of an integrated inventory management system capable of minimizing return rates caused by defective items and maximizing inventory turnover through accurate stock allocation between online and offline divisions.

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in Indonesia’s economy. However, most business actors have not fully implemented proper inventory accounting in accordance with standards. This study aims to analyze the recognition, measurement, presentation, and disclosure of raw material inventories at Pabrik Super Jaya and evaluate their compliance with the Financial Accounting Standards for Micro, Small, and Medium Entities (SAK EMKM). This research employed a qualitative descriptive method with primary data obtained through observation, interviews, and documentation. The results indicate that inventory recognition is still manual, using notebooks without formal evidence. Measurement is based on raw material costs, labor, and daily expenses, without formal methods such as FIFO or average. Financial reporting is limited to a simple income statement without detailed inventory or notes to financial statements. Disclosure is limited to physical quantities and nominal values. Thus, Pabrik Super Jaya’s inventory practices are not fully aligned with SAK EMKM standards

This study aims to compare two methods of raw material inventory management, namely Economic Order Quantity (EOQ) and Periodic Order Quantity (POQ), in improving efficiency and reducing operational costs at Konveksi Arey Hijab. The main problem faced by this company is the irregularity in raw material inventory management, which causes wasteful costs, especially ordering costs and storage costs. Based on raw material purchase data in 2024, which recorded a total purchase of 26,203 kg with a total cost of IDR 1,834,573,300, this study uses a descriptive quantitative approach to compare the two methods. The results of the study show that the EOQ method produces lower inventory costs, namely IDR 16,568,074, compared to the POQ method. The application of the EOQ method can reduce the frequency of excessive ordering, while the POQ method is more effective for ordering periods that are adjusted to seasonal demand. This study recommends that Konveksi Arey Hijab adopt the EOQ method to optimize raw material inventory management, reduce wasteful costs, and improve the company's operational efficiency.
