Abstract

Model drum dryer digunakan untuk mengeringkan berbagai biji-bijian atau produk pertanian. Salah satu kegunaannya adalah untuk mengeringkan gabah. Pemilihan desain silinder tipe horizontal yang digunakan dalam pengeringan ini akan mempengaruhi distribusi udara yang memasuki ruang pengering. Penelitian ini bertujuan untuk mengetahui distribusi kecepatan udara dan distribusi suhu dalam ruang pengering tipe silinder horizontal. Sehingga hasil simulasi akan mengetahui yang optimal bahwa proses pengeringan tersebut merata. Metode yang digunakan dalam penelitian ini adalah percobaan virtual dengan menggunakan software Computational Fluid Dynamics (CFD) sehingga hasil simulasi dapat memberikan gambaran distribusi kecepatan aliran udara pada drum dryer untuk memudahkan penentuannya desain ruang pengering. Sedangkan variasi kecepatan aliran udara menggunakan "4,5" m/s, "6,75" m/s, dan "9" m/s dan suhu "38,14" °C, "39,60" °C, "40,17" °C dan "41,55" °C. Dari variasi tersebut hasil simulasi CFD yang paling optimal didapat pada variasi kecepatan aliran udara sebesar 9 m/s dan temperatur 41,55 °C dengan nilai perpindahan kalor yang diperoleh di dalam chamber dan pengeringan dinding, masing-masing sebesar 3.931 W dan 31.354 W.

Abstract

Corruption in Indonesia has become a systemic and complex issue, posing a threat to economic, social, and political stability. Despite various efforts, including the establishment of the Corruption Eradication Commission and robust law enforcement, Indonesia’s Corruption Perception Index has remained stagnant or declined in recent years. This is primarily due to the inadequacy of conventional audit methods, which struggle to detect complex and hidden corruption schemes. This study examines how the role of investigative audits by the Supreme Audit Agency (BPK) can be optimized through synergy with the Whistleblowing System (WBS) to enhance corruption eradication efforts in Indonesia. Investigative audits, which focus on detecting fraud, are crucial as they can convert audit evidence into legal proof in corruption cases. However, the BPK’s role is often hindered by limited human resources, independence, and weak coordination. Using qualitative research and a literature review, this study analyzes relevant documents, books, scientific journals, and official reports to identify and classify relevant data. The findings indicate that strong synergy between BPK's investigative audits and the WBS is essential. Optimizing these two instruments requires significant reforms, including strengthening whistleblower protection laws, improving inter-agency collaboration, and fostering a robust anti-corruption culture. The study concludes that BPK’s investigative audits are effective in uncovering state losses, but their success depends on follow-up actions and coordination with law enforcement. The WBS can detect corruption early, but its effectiveness is limited by weak whistleblower protection and lack of trust in internal reporting channels.
