AUTOMATIC TRANSFER SWITCH UNTUK RUMAH TINGGAL SEDERHANA BERBASIS ARDUINO NANO
Full text linkAutomatic Transfer Switch (ATS) is a device that can move the main power source to a backup power source automatically and quickly when the main power source experiences a disturbance or cut-off of supply to the load. In this study, ATS was designed based on the Arduino Nano microcontroller as an automatic control that works based on voltage readings. Using the Arduino Nano microcontroller can facilitate the process of making tools and minimize the use of components. This ATS uses the PZEM-004T voltage sensor module. The voltage sensor module functions to detect and measure the value of the PLN voltage. From the test results, it was found that the time lag between the PLN supply being cut off until the generator was turned on and ready to load was an average of 2.76 seconds. Meanwhile, the time lag when the PLN supply turns on again until the generator supply is cut off and the load supply is again served by PLN is an average of 1.74 seconds. All working status of this ATS panel can be displayed on the LCD indicator, indicator light and analog voltmeter
IMPLEMENTASI KONTROL PROPORSIONAL, INTEGRAL DAN DERIVATIF (PID) TERHADAP KECEPATAN MOTOR DC
Full text linkRecently, research on DC motor has been rapidly developed, from the wether simple until the advanced / complicated . DC motor utilizes DC power connected to its armature and field (stator) winding, in which the power will be converted to mechanical energy. In addition, DC motor has beneficial in big initial torgue and simple velocity control. When DC motor given the burden of arbitrary, rotation speed of motor also change.PID method was employed to control the rotation speed remaining constant.
Implementation and simulation method was proposed in this research. The result shows that when 12,5 V of voltage was applied to DC Motor, at no load – open loop, the rotation speed was 2000 rpm. Increasing load up to 0,5 N.m, decreased the rotation from 2000 rpm to 1404 rpm. Furthermore, for closed loop using Proportional control (P), Proportional Integral (PI) and Proportional Derivatif (PD) control. proved that rotation of motor was unstable. Whereas, PID control method can stabilize the rotation of motor and give just response,reacling steady state at 3,4 s with 0,004 V of error

The result of the research shows that the design of hydroponic plant watering system has been developed. In the Ebb and Flow hydroponics system the process of administering the nutrient solution using a timer while the water temperature of the nutrients is kept optimum 18oC to 28oC using DS18B20 temperature sensor and chiller. While monitoring water level nutrition using water level sensors and GSM module. The GSM module sends a message when the water level of the nutrient reaches a certain level in the reservoir and the alarm will give notice of buzzer when the nutrient water is at low level
RANCANG BANGUN SISTEM INFUS CERDAS
Full text linkThe rapid development of the world of technology that covers almost all sides of life has encouraged innovation and human creation to make various tools with automatic work systems. Giving fluids using intravenous fluids is one way to enter fluids intravenously to meet the needs of fluids, electrolytes, drug administration, and feeding. The process of replacing intravenous fluids that has reached the minimum replacement limit must be carried out promptly and quickly, so that there will be no delay in changing intravenous fluids which will result in unstable pressure on the infusion set which will result in blood clots.
infusion set which will result in blood clots.In its testing, this tool can display information on the total number of intravenous fluid drops, and the condition of the remaining infusion fluid level on the LCD, as well as an additional display of the number of intravenous fluid drops per minute on theapplications client PC and / or smartphone. Adjusting the position of the mini servo of the infusion tap, can be adjusted when the appliance is not or not connected to the client. The sensor optocoupler used can also detect every drop of intravenous fluid. The reading of the sensor optocoupler used can experience an error by a difference of 100% if the dripping of the intravenous fluid is too slow. This is caused by the drip that is read twice by the sensor because one drop of intravenous fluid is read again after more than 50 milli second

KONSERVASI ENERGI LISTRIK PADA BANGUNAN GEDUNG KANTOR BUPATI TOJO UNA-UNA
Full text linkElectrical energy has a very important role in the economic, industrial and social development of the community, this causes an increase in the demand for electrical energy in line with the increase in people's welfare, economic and industrial growth. On the other side, energy sources that are commonly used for power generation are increasingly expensive and limited in availability and cause environmental pollution. Based on these considerations, it is necessary to implement an energy management program to preserve energy resources and use energy effectively. Energy consumption intensity (ECI) is a term used to determine the amount of electrical energy consumption in a room. The calculation of the intensity of energy consumption carried out at the Tojo Una-una regent's office in Central Sulawesi consists of 3 buildings with 129 rooms, it was found that 7 rooms were categorized as quite efficient and wasteful
