Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh variasi debit dan sudut kemiringan pipa terhadap beda tekanan dan pola aliran dalam sistem aliran dua fase, khususnya pada aliran gas dan cair. Debit air divariasikan dalam kisaran 0,00020 m3/s hingga 0,00030 m3/s, sedangkan debit udara divariasikan dalam rentang 0,0007 m3/s hingga 0,00040 m3/s. Variasi ini dilakukan pada tiga sudut kemiringan pipa terhadap horizontal, yaitu 30°, 45°, dan 60°. Hasil penelitian mengungkapkan bahwa beda tekanan pada aliran udara meningkat sejalan dengan peningkatan laju aliran udara. Pada debit cairan yang dijaga konstan, peningkatan beda tekanan juga terjadi sejalan dengan pertambahan laju udara. Sebaliknya, pada variasi debit gas yang dijaga konstan, beda tekanan meningkat seiring dengan pertambahan laju aliran cairan. Variasi sudut kemiringan pipa juga memberikan pengaruh terhadap peningkatan beda tekanan dalam sistem. Dalam hal pola aliran, pada sudut kemiringan 30°, ditemukan pola aliran yang meliputi gelembung dengan ukuran kecil dan besar, serta pola aliran berupa sumbat. Pada sudut kemiringan 45°, pola aliran melibatkan gelembung ukuran besar, sumbat, gelembung, dan sumbat dengan ukuran besar. Pada sudut kemiringan 60°, pola aliran mencakup aliran acak, gelembung ukuran sedang, sumbat, dan kembali ke pola aliran yang acak.

Abstract

The research evaluated inventory management (IM) strategies employed by small and medium-sized enterprises (SMEs) in Makassar City manufacturing sector, Indonesia. The study drew its participants from industrial zones including Sudiang, Perintis, Bumi Taman Permai, and Uripsumuarjo. Respondents were purposefully selected from companies within these areas. A qualitative, descriptive research design was adopted, utilizing purposive sampling. From a sample size of 244 participants, data was gathered through completed questionnaires. The study revealed that the majority of SMEs rely on the Just-In-Time (JIT) inventory management approach, with limited familiarity with other computerized inventory systems. Given the reliance on JIT, SMEs experience supply chain difficulties, as they must maintain consistent communication with suppliers and minimize material delivery times. However, due to a lack of computerized systems, orders are often placed only when needed, causing delays for customers. Based on these findings, the researchers suggested that further research be conducted to explore specific areas in greater depth.
