Abstract

Pada industri pengolahan crude oil, menjaga kinerja perpindahan panas yang optimal sangat penting untuk memastikan efisiensi energi dan kestabilan operasi. Heat exchanger (HE) merupakan komponen penting dalam proses pengolahan crude oil, khususnya pada tahap pemanasan awal sebelum crude oil masuk ke dalam furnace. Penelitian ini bertujuan untuk mengevaluasi kinerja HE-02 tipe shell and tube yang digunakan pada Crude Distillation Atmospheric Unit di PPSDM Migas Cepu serta memberikan rekomendasi untuk pengoptimalan alat berdasarkan hasil analisis yang diperoleh. Evaluasi dilakukan berdasarkan parameter efisiensi perpindahan panas, fouling factor (Rd), dan pressure drop. Hasil analisis menunjukkan bahwa efisiensi perpindahan panas HE-02 hanya mencapai 66,18%, lebih rendah dari standar minimum 80%, dengan nilai Rd sebesar 0,294 hr.ft².°F/Btu yang jauh melebihi batas maksimum 0,005 hr.ft².°F/Btu. Penurunan kinerja ini disebabkan oleh pembentukan kerak dari endapan parafin dan senyawa sulfur dalam crude oil. Meskipun demikian, sistem masih layak secara hidraulik karena pressure drop yang didapatkan sebesar 0,0104 psi di sisi shell dan 0,002567 psi di sisi tube, di mana hal ini sudah di bawah batas maksimal yang diizinkan yaitu 10 psi. Diperlukan tindakan preventif berupa pembersihan rutin dan evaluasi operasional untuk memulihkan performa alat dan menjaga efisiensi proses secara berkelanjutan.

Abstract

The issue of Good Corporate Governance (GCG) has developed over the centuries as a reaction to systemic crises or corporate failures. The well-documented failures of the Indonesian government are the 1997-1998 Asian financial crisis and the 2008 global financial crisis. Many experts regard Indonesia’s recession as driven by poor government oversight of the financial sector. This study aims to analyze the historical impact of GCG in Indonesia in the 1998-2020 period on government performance. This study employs Foucauldian archaeology and uses official government documents (laws and policies and their derivatives), books, journals, mass media articles (offline and online), and websites as data sources. The data analysis consists of several activities, including collecting, presenting, and inferring data. This study concludes that the development of GCG in Indonesia has increased from a regulatory perspective. However, the development of GCG in Indonesia impacts the government’s performance because there are still many problems in the practice of GCG in Indonesia. One of the problems is the Jiwasraya financial scandal. The Financial Scandal occurred due to the poor performance of the government, in this case, the Financial Services Authority (OJK), in supervising the insurance industry
