Abstract

The problem that often occurs in cubicles today is the corona, a phenomenon that occurs when the air around the conductor or conductor is ionized. This is what accelerates the occurrence of the corona. The design of the temperature and humidity control system is made using the Wemos D1 Mini microcontroller, the DHT11 sensor as a temperature and humidity reader sensor, this tool also uses a relay as an automatic switch to turn on and off the fan and also a dehumidifier and installed NodeMCU Esp8266 to send results to smartphones. The way the temperature and humidity control system works using the DHT11 sensor, the sensor senses the temperature and humidity objects in the cubicle, then the data obtained will be processed by the Wemos D1 Mini microcontroller in serial communication. Then the received data will be processed according to the set point, where the temperature is set at 35ºC and the humidity is set at 50% RH. So that if the temperature and humidity are more than the set point value, the relay will work to activate the dehumidifier and fan until the temperature and humidity reach the specified values then it will turn off again. And the data that has been read will be displayed on the LCD / smartphone and stored in the database. From the results of taking temperature and humidity data at substations SP13, KJ274 and KJ365, the results were obtained to test the prototype tool. It takes 8 minutes for the humidity to reach 79% of the initial value of 30% and 13 minutes for the temperature to reach 49ºC from the initial temperature of 26ºC. In the test, the prototype tool can control temperature and humidity to the bottom of the set point and keep it below the set point, so that the occurrence of coronas caused by high humidity can be minimized.

Abstract

ABSTRAKSalah satu faktor yang dapat mempengaruhi efisiensi panel surya adalah suhu pada modul panel surya. Efisiensi panel surya akan menurun seiring dengan naiknya suhu panel surya. Oleh karena itu, dibutuhkan suatu mekanisme pendinginan pada sistem panel surya untuk dapat meningkatkan efisiensi panel surya. Pada penelitian ini, dirancang sebuah sistem pendinginan panel surya dengan metode penyemprotan air dan pengontrolan suhu air. Jika suhu telah mencapai 40oC, pompa yang terdapat pada bak penampungan air akan bekerja mengalirkan air ke permukaan panel surya. Dengan demikian, suhu pada panel surya dapat dikontrol agar sesuai dengan set point yang diinginkan yakni di bawah 40oC. Sistem pengontrolan suhu air dengan peltier dan fan dilakukan untuk mengontrol suhu air di dalam bak penampungan air agar tetap berada pada suhu maksimal 39oC. Sistem pendinginan panel surya pada penelitian ini mampu meningkatkan daya keluaran panel surya sebesar 30,19%.Kata kunci: panel surya, pendingin, semprotan air, peltier ABSTRACTThe solar panels efficiency can be affected by the the temperature of the solar panel module. It will decrease as the temperature of the solar panels increases. Therefore, a cooling mechanism in the solar panel system is needed to increase the efficiency of the solar panels. In this study, a solar panel cooling system was designed with the method of spraying water and controlling water temperature. If the temperature has reached 40oC, the pump in the water reservoir will work to circulate water to the surface of the solar panel. Thus, the temperature on the solar panel can be controlled to match the desired set point, which is below 40oC. The water temperature control system with peltier and fan is carried out to control the temperature of the water in the water reservoir so that it remains at the maximum temperature of 39oC. The solar panel cooling system in this study was able to increase the solar panel output power by 30.19% when using the cooling system.Keywords: solar panels, cooling, water spray, peltier

Abstract

Have been created a quad-ridge horn (QRH) antennas the working frequency at 8GHz - 12 GHz. This type of antenna is commonly used in the RADAR (Radio Detection And Ranging) and Detection Systems. The design results will be simulated using WIPL-D software to find out whether the design results are appropriate or not with the desired conditions. The next stage is the manufacture of antennas and the entire implementation of the fabrication carried out in the lathe service workshop to obtain precise size results. Because the size of the antenna is small (10cm - 20cm), with a thickness of ±10mm stainless-steel material, so it is not possible to do it alone. The quad-ridged horn antenna performance will be observed in testing using a vector network analyzer (VNA) measuring device whose working frequency ranges from 100KHz - 8.5GHz. The measurement results obtained, QRH antenna works at 8.33 GHz frequency. With the difference in antenna working frequency practically it will affect other variables such as return loss, VSWR, gain and antenna radiation diagram. This is due to differences in the dimensions of the antenna which has a shift in the value of several centimeters (cm) when in the fabrication process.

Abstract

The mosque is a place of worship for Muslims. The Ministry of Religion issued provisions regarding different designations for mosques. One of the prayer rooms in Kelurahan Kreo Selatan is the Al-Hasanah Mosque which is located at Gang Sawo No. 27, RT.01/RW.13, Kelurahan Kreo Selatan, Kecqmqtqn Larangan, Kota Tangerang, Banten. Al-Hasanah Mosque congregation is growing rapidly and DKM intends to expand the mosque building and turn it into a mosque. The current condition of the Al-Hasanah prayer room consists of a 1-story building. And the early history of this prayer room was a house belonging to the congregation which was then donated to become a prayer room. The current condition of the Al-Hasanah Mosque needs to be developed because the congregation of the Al-Hasanah Mosque is increasing and is becoming increasingly unaccommodated. Based on these conditions, Budi Luhur University Architecture Study Program organized Community Service activities to jointly prepare the Al-Hasanah Mosque Renovation Budget Plan. The method of implementing the activities uses the Architectural Design Process. Where the renovation design of the Al-Hasanah Mosque is adjusted to the input from the mosque manager, while the working drawings of the mosque renovation design are adjusted to architectural standards. Then proceed with the calculation of costs (RAB) based on the preliminary drawings that have been mutually agreed upon
