Abstract

Abstract. PT. Indonesia Pos Chemtech Chosun Ref is engaged in the refractory industry and supplies the refractory needs of PT Krakatau Posco, which is one of the largest steel mills in Indonesia. IPCR uses 3 types of mixer machines, namely K-Mixer, D / C Mixer, Wet / P Mixer. The refractory production stage starts from weighing and selecting raw materials, then continued with the process of mixing raw materials with the K-Mixer machine for high temperature refractories. These results have met the standards set by the Japan Institute of Plant Maintenance which is 85%. The proposed improvement using the planned maintenance pillar by means of inspection and repair when the machine is damaged, or called corrective maintenance. Abstrak. PT. Indonesia Pos Chemtech Chosun Ref bergerak di bidang industri refraktori dan menyuplai kebutuhan refraktori PT Krakatau Posco yang merupakan salah satu pabrik baja terbesar di Indonesia. IPCR menggunakan 3 jenis mesin mixer, yaitu K-Mixer, D/C Mixer, Wet/P Mixer. Tahap produksi refraktori dimulai dari penimbangan dan pemilihan bahan baku, kemudian dilanjutkan dengan proses pencampuran bahan baku dengan mesin K-Mixer untuk refraktori temperatur tinggi. Hasil tersebut telah memenuhi standar yang ditetapkan oleh Japan Institute of Plant Maintenance yaitu 85%. Usulan perbaikan menggunakan pilar perawatan terencana dengan cara inspeksi dan perbaikan ketika mesin mengalami kerusakan, atau disebut dengan corrective maintenance.

Abstract

Tiakur City, the capital of Southwest Maluku Regency, has undergone significant physical development between 2015 and 2025, driven by population growth and economic activities. This study employs a quantitative approach using remote sensing technology with PlanetScope satellite imagery to analyze land cover changes. The analysis reveals an increase in built-up land area from 171.29 hectares (7.31%) in 2015 to 395.66 hectares (16.89%) in 2025, while non-built-up land experienced a decline. These findings indicate a rapid development rate and highlight the importance of sustainable spatial planning. In conclusion, understanding the patterns and intensity of land cover changes in Tiakur City is crucial for evaluating spatial planning policies and improving infrastructure development planning for the future.
