One of the factors that affect the value of soil resistance is soil temperature and humidity. This research designs a monitoring tool for soil temperature and humidity values to monitor soil resistance values remotely based on IoT (Internet of Things) so that it can be monitored periodically every 10 minutes within 24 hours for 3 days with two conditions, namely rainy and normal weather. The re…
Aluminum alloy 7075 is aluminum which has the main composition of Al, Zn, Mg, Cu, and a small part plus other metals. To increase the ability of the material to withstand fatigue loads, heat treatment is carried out. The heat treatment carried out is T6 heat treatment which goes through 3 processes, namely Solution Heat Treatment, Quenching and Artificial Aging. The heat treatment solution carr…
Hydroxyapatite is a derivative of calcium phosphate and is not a small part of it is also used for coating on bones because it is very good biocompatible. Copper was chosen as undoubtedly because it works to improve angiogenic and antibacterial hydroxyapatite. The addition of copper in the biomaterial is currently being prepared because it is expected to improve the biological properties of bon…
