Hard water causes the CaCO3 scale formation on the pipe walls and heat exchanger equipments in industrial or domestic water processes. A great number of experimental researches on the prevention of the CaCO3 precipitation process by magnetic field have been carried out. In this research, Na2CO3 and CaCl2 solutions was...

Dimethyl ether (DME) is a type of renewable energy that could replace the use of fossil fuel in Indonesia. Nevertheless, DME can cause degradation of rubber-based materials. Therefore, the performance of rubber that has been degraded by DME must be improved. This research study aims are to determine the degradation...

Magnetisasi air sadah yang bertujuan menurunkan kesadahan air merupakan proses fisik guna mencegah terbentuknya kerak (CaCO3) pada sistem perpipaan. Campuran larutan Na2CO3 dan CaCl2 digunakan sebagai model air sadah sintetik guna mengamati pengaruh medan magnet terhadap pembentukan partikel CaCO3 dalam air sadah. Variabel proses meliputi waktu magnetisasi, kuat medan, dan...
