Abstract

The result of a turning process is strongly influenced by the process parameters that could result in the product to be unacceptable. The cutting parameters may be determined according to the material hardness and roughness of the workpiece surface. The purpose of this paper is to investigate the effects of cutting speed and feed rate on surface roughness and vibration. In Taguchi method, the number of experiments is reduced by orthogonal arrays while  the effects of uncontrollable factors are also also reduced. The Taguchi method is used to reduce track, experimental time and production cost. Simple and precise are the most benefits of this method. Unstable vibrations in machining operations, known as chats, can cause damage to tools, workpieces, and machine tools. Cutting force is found to be the most dominant factor affecting surface roughness.

Abstract

Background: Reliable pharmaceutical logistics is essential for continuous access to essential medicines, particularly in disaster-prone settings. This study assessed drug logistics management for disaster preparedness at Tipo Public Health Center, Palu City, Indonesia. Methods: A qualitative case study used in-depth interviews, document review, and observation. Informants included the head of the health center, the pharmacist/person in charge, and pharmaceutical unit staff. Data were triangulated and analyzed with content analysis. Results: Drug planning is conducted quarterly through a multidisciplinary process guided by stock evaluation, consumption trends, and local disease patterns. Constraints included uncertainty in patient volume and case mix, network disruptions affecting the electronic ordering system, and discrepancies between quantities requested (LPLPO) and supplies received from the district warehouse, limiting buffer stocks for emergencies. Conclusion: Although collaborative planning aligns medicines with community needs, technological and supply-chain constraints hinder procurement and disaster readiness. Strengthening network infrastructure, improving coordination with the health office and warehouse, and establishing contingency plans and flexible stock adjustments are needed to ensure timely medicine availability during disasters.
