Rancang Bangun Teknologi Peningkatan Konversi Energi Menggunakan Pembersih Debu Otomatis Dan Reflektor Pada Panel Surya Berbasis Mikrokontroler Arduino
Full text linkSolar energy is one of the most potential renewable energy sources, but the performance of solar panels can decrease due to dust accumulation on the panel surface. This study aims to design and build an automatic dust cleaning tool based on an Arduino microcontroller equipped with a reflector to increase energy conversion in solar panels. This system uses a dust sensor to detect the level of dirt on the panel, as well as a drive motor to automatically clean the panel surface when the dust reaches a certain level. Based on the test results, there was an increase in the output voltage of the solar panel after the cleaning process, with an average increase of 0.5 to 1.5 Volts. In addition, the use of a reflector helps increase the intensity of light received by the panel, especially in the morning and evening. With this automatic system, the efficiency of the solar panel can be maintained without periodic manual intervention. The results of the study indicate that this tool is effective in improving the performance of solar panels and has the potential to be applied to small to medium-scale installations

Rancang Bangun Alat Sortir Otomatis Buah Apel Dan Buah Jeruk Berbasis Arduino Uno 328
Full text linkThe average livelihood in Indonesia is farming, with Agriculture Minister Limpo stating an increase of 8 million farmers during the Covid-19 pandemic. Although economic activity has decreased, the agricultural sector has experienced a significant increase, especially plantation commodities as a contributor to the country's foreign exchange. In this context, the process of sorting fruits such as apples and oranges is important to determine classification based on quality. The design of an automatic sorting tool uses Arduino Uno 328 as a processor of input signals from proximity sensors, color sensors, and ultrasonic sensors. The proximity sensor detects the presence of fruit, while the color sensor identifies the color, and the ultrasonic sensor distinguishes the size. The output is displayed on the LCD, which shows data on the size and color of the fruit. The working principle of this tool is that the proximity sensor detects the presence of fruit entering the conveyor, with data sent to the Arduino and displayed on the LCD. The color and ultrasonic sensors also send relevant information. The servo motor drives the conveyor, directing the fruit to the place according to size. Test results show that the proximity sensor functions effectively at a distance of 1-5 cm, while the ultrasonic sensor shows a range of 3.2-10.4 cm, and the power consumption of the tool reaches 120 watts
Implementasi Algoritma Fifo Terhadap Sistem Antrian Pasien di Rumah Sakit Berbasis Web Online
Full text linkThe development of queuing systems in hospitals continues to be developed to optimally support patient service, especially regional general hospitals (RSUD). This is because the manual system is still inefficient, resulting in patients queuing for a long time and conflicts often occur. Based on these problems, a Web system was designed with the support of the Fifo algorithm so that the queuing system becomes simpler and more optimal. An easier and more flexible queuing system will support better and more excellent hospital services. Implementation of the Fifo Algorithm, designed to determine and calculate the patient queue system and orderly service for patient registration at the hospital. The implementation of this automatic queuing application will have an impact on health services, especially at Dr. Djasamen Saragih, Pematang Siantar city. The results of using a web-based application in this hospital have an impact in making it easier for operators or admins to queue up calls for patient serial numbers. The operating system on the website is monitored. If the web status has a data result of 1, the patient has been called by admin, but if the patient has not been called, the monitoring site is in Web with value 0 or null
