vicky Penerapan Sistem ATS (Automatic Transfer Switch) sebagai Pengendalian, Pemantauan, dan Perawatan Berbasis IoT (Internet of Things)
No full textThe need for electricity is increasing along with population growth. The main electricity supply (PLN) is not always continuous in its distribution, so alternative power is needed, namely generators. The ATS (Automatic Transfer Switch) system can transfer the voltage source to the load. The ATS system is equipped with IOT in the form of a Blynk application on Android which functions as a controller and can send ATS damage notifications. This research was conducted to meet the electricity needs. Users can monitor, control and maintain the ATS system in the event of a breakdown. The method in this study uses a quantitative method, namely data collection by testing the ATS system and testing the IOT Blynk application function as a notification of damage to the ATS system. The result of transferring the PLN voltage to the generator is only 7 seconds and 3 seconds vice versa. There was damage to the lamp cable 1 time, the relay 1 time, and the fan cable 2 times. The results of measuring the current and voltage of the PLN source: lamp load 0.02A, 3.4V; fan 0.04A, 3.5V; AC motor 0.04A, 4V. Generator current and voltage measurements are as follows: lamp load 0.02 A, 9.1V; 0.03A, 9V fan; AC motor 0.05A, 4.5V.
 
Prototype Sistem Kendali Pintu Gerbang Otomatis Berbasis Internet of Things (IoT): Indonesia
No full textAn automatic gate is a door whose operation process runs automatically using a remote drive tool, but when combined with IoT elements, it means that users can control the automatic gate using a cell phone or mobile phone. The purpose of this research is to create a prototype of an automatic gate control system based on the Internet of Things (IoT). The method used in the current research is the prototype method. The results in this study were tested to determine the range. Testing is done using an adapter connected to a power supply. The testing process is carried out by observing the movement and response of the servo motor when controlled via a smartphone and the stepper motor when the Ultrasonic sensor detects an object less than 5 cm. The conclusion of this research is that at a distance of 1 to 19 meters, the gate lock can still be controlled properly. While at a distance of 20 meters when the gate lock is open, the gate opens and closes. This is because the WiFi signal cannot be captured properly by the central controller of the circuit at a distance of more than 19 meters.
 
Optimalisasi Labview Sebagai Kendali dan Monitoring Arus Tegangan pada Modul Solar Cell Menggunakan Jaringan Lokal
Get PDFRenewable energy sources in Indonesia have been widely used, one of which is solar energy, for various needs, one of which is for solar power generation by using solar cells as the medium. In generating electricity, solar cells are very dependent on the intensity of the sun so as to produce currents and voltages that are not constant. Because of this, a monitoring system was created to monitor the current and voltage in a solar cell module to determine current and voltage conditions. In this study, the monitoring system used wireless data transmission via the XBee S2C module installed on the Arduino Mega 2560 and Arduino UNO. The INA 219 sensor is mounted on a solar cell module along with a relay module connected to the Arduino Mega 2560 and the XBee S2C module. The test results show that wireless data transmission cannot be used indoors at a distance of more than 20 meters. The INA 219 sensor as a reader for DC current and voltage parameters has an error rate of 0.49% to 0.75% for voltage and for DC current readings it has an error rate of 1.85%. The results of current and voltage readings are displayed on a LabVIEW interface in real-time and can be accessed via a web browser using a local network. Relay control carried out through LabVIEW has a delay time of 6.08 seconds. Logging data can be stored in .xls files and data displayed on a web browser has a delay of one to two seconds

Get PDFIndonesia is an agricultural country with 40% of the population\u27s livelihood provided by farmers. Harvested rice typically has a moisture content of 20-27% on a wet basis. The type of artificial dryer that is often used is the tub or rotary type. This research aims to develop a rice dryer using a combined tray and rotary-type method. Based on the result, the higher the speed dryer, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. The higher the speed, the shorter the drying time. The net result of this test is that the relationship between time and engine speed is inversely proportional. Rice drying results can be described as dry, but not including ready-to-eat rice standards. The higher the speed, the shorter the drying time
Uji Performa Model Batam Marine Ambulance Sebagai Armada Pendukung Medis dan Logistik
Get PDFThis study aims to test the performance of the Batam Marine Ambulance model as a medical and logistics support fleet using the comparison ship method. A series of stability and motion analysis processes were carried out, then the results were assessed to determine the best design among the proposed design options. Performance tests used three ship models (Model I, Model II, and Model III). It is known that in the stability test, the tilt angle of model III is 33.63° and the maximum GZ value is 4.673 cm. Then, in the resistance test, Model I has a lower resistance of 87.29 N and the required power is 1496.93 W compared to the other proposed models. In the seakeeping test, Model III was found to be more stable or less affected on all surface conditions because the RAO value was relatively lower, namely 90o in terms of heaving, rolling, and pitching at 135o and 180o then had lower additional resistance. The Model III design has good ship stability, drag, and seakeeping characteristics

This study used an experimental method using two types of filament material: nylon carbon fiber and PLA carbon fiber with a diameter of 1.75 mm for each filament and a recommended printing temperature of 190-260°C. Both types of filaments were printed using a direct extruder type 3D printing machine with a build size of 180 mm x 180 mm x 180 mm and printing was carried out at atmospheric pressure and a horizontal printing area. The Universal Testing Machine carried out mechanical properties testing implementation related to tensile strength and strain. Based on the results of experiments and tests that have been carried out, the strain values ​​are 16.970 – 26.681% and the tensile strength is 19.244 – 23.899 MPa for nylon carbon fiber filament material. Whereas the PLA carbon fiber filament material, the strain value is 7.673 – 15.546%, and the tensile strength is 18.580 – 24.552 MPa. Therefore, based on the test results, it is known that the fill density parameter value has an influence on the strain value and tensile strength so that it can be used as a reference in setting machining parameters

Pengaruh Arang Aktif Bidara dalam Menunda Kematangan Buah Klimakterik Tomat (Solanum lycopersicum)
Get PDFTomato (Solanum lycopersicum) is classified as a climacteric fruit that is easily damaged, especially during the storage and shipping process, so proper postharvest management is needed. Postharvest management of climacteric fruit can be overcome by inhibiting the process of respiration and transpiration using activated charcoal. Activated charcoal works by absorbing ethylene gas during the respiration process. This study aims to analyze the use of bidara activated charcoal variations as an inhibitor of tomato ripeness and to examine changes in fruit quality during the 10day storage. The research used One Way Anova analysis with one factor of variation of activated charcoal with control treatment, 1gr, 3gr, and 5gr.
