Abstract

Air conditioners (AC) and water heaters have become common needs in households and the hotel industry. This shows that the need for electric power is increasing. To reduce electricity consumption which is high enough. Engineering technology needs to be done for air conditioning as well as water heating. This engineering is called ACWH (Air Conditioner Water Heater). The way the ACWH system works is to utilize the wasted heat from the AC system to heat water with the addition of a fin heat exchanger, where the heat exchanger is designed to utilize the energy already in the system. This study used experimental research methods by testing at temperatures of 16, 18 ?, and 20 ? AC. The test results showed that the finned shell helical coil type heat exchanger was able to produce a water temperature of 55 ? in the test with an AC temperature of 18 ?.

Abstract

The city of Medan constitutes one of the cities that has the potential for the development of freshwater fish farming, this is because it can help the economy and income for fish farmers. However, the lack of understanding of tilapia farmers on poor water quality conditions resulted in slow fish growth. Then the lack of monitoring time carried out by fish pond cultivators makes harvest yields also not optimal due to water conditions that can change at any time due to various factors, coupled with the maintenance process also causes a decrease in production yields, one of which is when infectious or non-infectious diseases occur. The objective of this program is to find out about understanding water conditions, pH, and water levels, as well as to assist the process of monitoring tilapia pond water automatically using a smartphone. The stages carried out, begin with problem investigation, problem analysis. Then design the measuring instrument and finally do the simulation/analysis of the tool. The results of this program have succeeded in making a smartphone-based pH and water level measuring instrument with simulation results showing the water level in the fish pond with an average of 2.4 and the average pH value of fish pond water being 7.1. However, in the development of further tools, it is necessary to manufacture a signal transmitter that supports the amplification of measuring devices in sending data to smartphones.
