Abstract

Pompa pendingin primer JE01 AP003 merupakan salah satu komponen utama pada keselamatan operasi reaktor sehingga perlu dilakukan deteksi awal jenis dan tingkat kerusakan komponen penyusunnya. Komponen utama dari pompa yang sering mengalami kerusakan adalah bearing. Salah satu indikasi bearing telah mengalami kerusakan yaitu adanya vibrasi atau kenaikan suhu pada bearing. Tujuan dari penulisan ini adalah untuk mengetahui gejala kerusakan bearing dan tingkat kerusakannya berdasarkan analisis vibrasi. Salah satu cara  untuk mendeteksi awal gejala kerusakan pompa adalah dengan mengetagui respon vibrasi hasil pengukuran dengan vibration tester. Berdasarkan analisis vibrasi akan diperoleh cited peak pada arah radial, aksial dan tangensial. Dari hasil analisis vibrasi tersebut maka dapat ditentukan gejala kerusakan pada free end bearing pompa pendingin primer JE01AP003 berupa looseness dengan tingkat kerusakan moderate sehingga perlu dilakukan penggantian bearing JE01 AP003 meskipun kerusakan yang terjadi belum parah.Abstract VIBRATION ANALYSIS OF PRIMARY AIR PUMP JE01 AP003. JE01 AP003 primary coolant pump is one of the main components in the safe operation of the reactor so that needs to be done early detection of damage types and levels of its constituent components. The main components of the pump that is often damaged bearing. The purpose of this paper is to know the symptoms of bearing damage and the level of damage based on vibration analysis. One indication of the bearing has been damaged, that is the vibration or temperature rise in the bearing. One way to detect early symptoms of damage to the pump is to use the vibration response peak Based on the analysis of the measurement results cited the obtained results that the primary coolant pump JE01 AP003 has been damage to a free end looseness bearing with moderate levels of damage. Need JE01 AP003 bearing replacement even though the damage is not severe.

Abstract

Telah dilakukan analisis ketebalan pipa pada sistem pendingin sekunder Reaktor Serba Guna. Siwabessy (RSG GAS) dalam rangka pelaksanaan program manajemen penuaan. Analisis dilakukan melalui inspeksi visual, pengukuran ketebalan dengan metode ultrasonik dan analisis unsur kimia. Lokasi analisis ditetapkan berdasarkan kondisi aliran fluida di dalam pipa dan susunan perpipaan. Hasil analisis menunjukkan bahwa pipa pada sistem pendingin sekunder telah mengalami penipisan yang disebabkan oleh proses korosi, yaitu korosi homogen dan korosi sumuran. Untuk memperlambat laju penipisan agar tercapai umur desain maka perlu dilakukan peningkatan kualitas air untuk memperlambat terjadinya proses korosi pada pipa.

Abstract

The development of digital technology has driven structural changes in the media system, information production patterns, and the relationship between media, the state, and society. The author presents a descriptive-narrative analysis of the dynamics of the political economy of digital media by utilizing several critical theories: the political economy of media (Mosco, McChesney, Dwyer), the cultural industry (Adorno & Horkheimer), hegemony (Gramsci), framing (Entman), the propaganda model (Herman & Chomsky), and digital capitalism (Fuchs, Srnicek, Zuboff). This study also combines a literary approach with empirical examples in Indonesia, including the phenomenon of buzzers, political influencers, digital polarization, and the role of platforms such as TikTok, YouTube, Instagram, and WhatsApp in shaping public opinion. The findings show that the media structure in Indonesia is now hybrid, combining conventional media ownership oligarchy and global platform oligopoly, and creating a fragmented public sphere. This research emphasizes the need for a new theoretical model capable of explaining the interaction of the state, capital, and platforms within the framework of digital capitalism.
