System Design Optimization of the Acid Catalyst Concentration for Synthesis of Anti‐Cancer Agent Gamavuton‐0 by Using Mathematical and Statistical Software

21 logic then the microcontroller will turn on the rightmost relay to be opened up to D , which normally do not receive the voltage of over V. Figure 2. Battery charging schematics 2.3. Inverter nverters used here is a C, MOSFET transistors, A transformer, and relays. C is used as a square wave generator which will switch the MOSFET transistor RF N to perform the push pull transformer, using the MOSFET type transistor inverter is expected to be able to bear loads up to watts. Relay on the inverter is used as switch when battery condition has not yet reached the minimum charge or fully charged the inverter can not be switched on. Figure shows the inverter’s schematics.

3. Testing And Analysis

3.1. LDR Light SensorTesting Testing the sunlight sensor circuit using LDR is done by measuring the voltage at the output of the LM which will go into the microcontroller ADC PORT ATMega8 . Table shows the test results. Table . Light Sensor Testing Results Time V out LDR volt V out LM324 volt East Center West East Center West . ‐ . . . . 8 . . . 3.2. Inverter Testing DC to AC inverter testing is done by providing a direct current voltage of volts. n order for DC to AC inverter circuit of watts to work, the voltage supplied volts, and the output section connected by a digital voltmeter and digital ammeters. C CD is used as a generator. The following Table shows the result of testing watt inverter using a load of three light bulbs of watts each. 217 Table . nverter Testing Result Battery status Load Stats Load 1 Load 2 Load 3 , volt ON ON ON . volt ON OFF OFF 3.3. Solar Cell module Testing Solar cell testing was conducted from : to : with direct measuring of the output voltage on the poles of the solar cell module. Figure shows the measurement scheme and Table shows the measurement result. Figure 4. Solar cell module Vout measurement Table .
