Abstract

This research was conducted to develop the utilization of starch from talas kimpul (Xanthosoma sagittifolium), which is currently only used as a food ingedidient. In this study, an edible film was made by varying the starch of talas kimpul with Polyvinyl Alcohol (PVA) in order to obtain an edible film that met the requirements. Edible film was made with a ratio of talas kimpul starch-PVA, namely F1 (1:1), F2 (1:2) and F3 (2:1) with a total of 6 grams of polyblend in 100 ml, the plasticizer used was poly ethylene glycol (PEG) as much as 30% of the total polyglene. The edible film was prepared using the solvent casting method with the principle of gelatinization. The edible film obtained were characterized: organoleptic, thickness, pH, moisture content, absorption profile, percent elongation, tensile strength, Young’s modulus, and water vapor transmission rate. The results indicated that all formulas meet the requirements as edible film.

Abstract

The management of essential drug inventory is a strategic component of hospital pharmaceutical services because it directly influences service continuity, cost efficiency, and the overall quality of healthcare delivery. Poor inventory control can result in excessive stock accumulation, increased risk of drug expiration, inefficient budget utilization, and potential drug shortages that may compromise patient care. This study aims to evaluate the effectiveness of essential drug inventory control at Pekerja General Hospital by applying the ABC-VEN, Economic Order Quantity (EOQ), and Reorder Point (ROP) methods. It also examines differences in inventory management efficiency between 2024 and 2025 based on inventory value, cost of goods sold (COGS), and Inventory Turnover Ratio (ITOR). A mixed-methods approach with a sequential explanatory design was used. Quantitative analysis involved a paired sample t-test comparing inventory data from 2024–2025, while qualitative data were collected through in-depth interviews and analyzed thematically using NVivo. The findings reveal a significant improvement in inventory management in 2025 (p < 0.05), reflected in reduced inventory value and COGS, along with an increased ITOR. However, the implementation of ABC-VEN, EOQ, and ROP methods has not been fully integrated, and challenges such as limited human resources and procurement bureaucracy persist.In conclusion, although inventory control became more efficient in 2025, further integration of inventory methods and strengthening of human resource capacity are necessary to ensure sustainable improvements.
