The increase in industrial and domestic activities has led to environmental pollution through wastewater, which can impact water quality. One of the key parameters in monitoring wastewater quality is electrical conductivity, which reflects the concentration of dissolved ions in the solution. This study aims to design and develop a real-time monitoring system for wastewater conductivity using th…
It has been done the research about “The Effect of Methanol Amount and Heating Temperature to Biodiesel Properties from Ketapang Seed Oil (Terminalia Catappa Linn) Using NaOH Catalyst”. The purpose of research is to determine the optimum condition of making methyl ester with parameters include temperature variations (40, 50, 60, 70 °C) and methanol (10 : 90, 20 : 80, 30 : 70, 40 : 60, 50: …
