The Asset Integrity project is one of the strategic priorities in maintenance to ensure the functional lifetime of an asset is well maintained to support the nickel processing. The coating protection application is one of the asset integrity strategy to maintain the structural lifetime, however the corrosive environment of nickel processing plant influences the lifetime of the coating design differently on each facility due to different process in the processing line. The objective of this study is to predict the coating design lifetime on Dryer, KILN, Furnace, and Converter facilities. The analysis used regression method for coating lifetime on each facility by considering the independent variables, i.e. SO2 Intensity, stack emission, NOx emission, rainfall intensity, and underfilm condition. By using regression model, coating design lifetime in Dryer area is 4.95 years, KILN is 5.73 years, Furnace is 6.23 years, and Converter is 6.73 years. Process plant area which having the most significant impact of corrosive environment is Dryer area, causing the coating lifetime in this area is the lowest than other area in the Process Plant area. This result can be used to set maintenance strategy for coating design lifetime lifecycle for the next Asset Integrity project.
Berbagai penelitian sebelumnya tentang upaya untuk meningkatkan pelaksanaan perbaikan di lingkungan kumuh menunjukkan bahwa salah satu aspek penting adalah keterlibatan pemangku kepentingan yang ada. Kabupaten Tuban melakukan upaya untuk mengembangkan kawasan kumuh yaitu melalui Program KOTAKU. Penelitian ini bertujuan untuk mengidentifikasi pemangku kepentingan yang memiliki suara dalam perbaikan kawasan kumuh, salah satunya melalui Program KOTAKU. Data yang digunakan dalam penelitian ini bersumber dari berbagai penelitian terdahulu tentang bagaimana merehabilitasi kawasan kumuh dengan berbagai metode yang ada. Metode analisis yang digunakan dalam penelitian ini adalah analisis deskriptif kualitatif, dengan pendekatan analitik berupa analisis matriks dampak dan kepentingan Eden dan Ackermann. Penelitian ini mengidentifikasi sepuluh pemangku kepentingan yang berpartisipasi dalam pola kemitraan dan mengklasifikasikannya sebagai berikut: 4 key players (bupati, SKPD, tim Pokja PKP, dan lurah), 2 context setters (askot KOTAKU dan tim fasilitator kelurahan), 1 subject (masyarakat yang tinggal di kawasan permukiman kumuh), dan 3 crowds (BKM, TIPP, KSM/KPP).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
