<![CDATA[Penggunaan energi terbarukan semakin banyak diterapkan dalam kehidupan sehari-hari, khususnya pada pemanfaatan energi dari matahari dengan bantuan perangkat sel surya. Energi dari sel surya secara luas dapat digunakan dalam memenuhi kebutuhan berbagai macam perangkat yang memerlukan energi listrik, salah satunya dapat digunakan sebagai sumber daya utama untuk pengoperasian perangkat prototipe desalinasi dual output. Perangkat ini memiliki fungsi dapat memproduksi air tawar dan kristal garam secara bersamaan melalui proses distilasi. Dengan menggunakan sel surya sebagai sumber daya utama, maka proses tersebut sangat ramah lingkungan dan murah dalam biaya operasionalnya, namun banyaknya energi listrik yang dibangkitkan oleh sel surya sangat tergantung dari cuaca di sekitarnya. Untuk mengefisienkan penggunaan energi sel surya maka peneliti memiliki solusi dengan menerapkan sensor suhu sebagai kontrol otomatis dalam menghidupkan dan mematikan elemen pemanas pada proses distilasi. Hasil yang didapat berupa sistem kontrol menggunakan perangkat mikrokontroler dan sensor suhu yang mampu secara akurat mengendalikan elemen pemanas dengan menyalakannya saat suhu di bawah 100oC dan mematikannya saat suhu di atas 100oC sehingga tidak terjadi pemborosan listrik saat proses distilasi pada suhu tinggi.]]>

<![CDATA[Watering plants usually done manually using human power. that has risk negligence and inaccuracy. also, in time and cost is not efficient. Another factor that can affect the quality of crops is a factor of humidity and temperature. For those reason, writers made a tool that can work according to the level of humidity and temperature automatically and continuously. This tool uses Zelio Smart Relay as automatic controller. The 808H5V5 humidity sensor and LM35 temperature sensor is used as input. The LM35 temperature sensor detect the ambient temperature, where as 808H5V5 humidity sensor detect ambient air humidity, and time of watering adapted to the Smart Relay timer. The entire sensor input is programmed using ZELIO SOFT 2. Setting the temperature and humidity when the detected 30oC and >70% as well as the timeshows at 08.30 – 09.00 am and 16.00 – 16.30 pm the pump will automatically ON.]]>

<![CDATA[LPG (Liquified Petroleum Gas) is one of the important sources of energy. When compared with other fuels such as oil or firewood, LPG is very practical to be used for household because the material is produced from gas. But behind its practicality, it turns out that LPG gas can cause a danger if not used carefully. According to statistics, the second position of causing fire is a leaky gas cylinder that was ignited by a fire source. To overcome this problem, there a lot of research that uses special tools that can be used to detect leaks for LPG. In the design of the tool, most researchers used MQ-6 type sensors that were indeed built to utilize LPG gas. But studies on the characteristics of MQ-6 have not been done much, especially about the sensitivity of this sensor when used to detect LPG gas at a certain distance, so it needs to be researched about sensor placement. Therefore, in this study the sensitivity testing of the MQ-6 sensor was carried out. The results obtained at a distance of 10 to 30 cm, this sensor is very sensitive in detecting the presence of gas, but at a distance of 30 to 110 cm, it is less sensitive to detect presence of LPG gas because it can only support 10% of the total amount of gas in the air at a distance of 110 cm.]]>

<![CDATA[The development in this era is increasing, humans expect a tool or technology that can help human work, because now technology has become a human need. Therefore, a device that can do watering the wine is made automatically. This tool aims to replace manual work to be automatic. The benefits that can be obtained from this tool is that it can facilitate human work in watering grapes. This tool uses a soil moisture sensor which functions as a soil moisture detector and sends commands to Arduino uno to turn on the relay driver so that the pump can flush water according to soil needs automatically. The making of this final project is done by designing, creating and implementing system components including Arduino uno as a controller, relay drivers for turning on and off the water pump, LCD (Liquid Cristal Display) to display soil moisture values. The results of the research prove that the tool made can function properly and can be developed as expected. The tool can water the vine when the soil humidity is below 50%, and turn off the pump when the soil moisture is above 50%.]]>

<![CDATA[In general, conventional cattle sheds using manual systems and human labor are very reliable, in the conventional process of heating cattle sheds, we still encounter many using oil stoves and lamps as a DOC heating process. However, the use of oil stoves and lamps is dangerous and unstable. In addition to the DOC heater using the lamp, there is also a DOC heater using an element heater. The advantage of using a heating element, the temperature can be adjusted according to your needs. The use of heating elements in chicken coops is still rarely used. Therefore, a research was conducted on the manufacture of a temperature and humidity monitoring control system based on Arduino Mega in the Day Old Chicken (doc) cage. DHT 11 sensor accuracy level calibrated with room temperature measuring instrument Taffware HTC-2 is known DHT 11 sensor has an accuracy in reading temperature that is 96% with a dispute of 3.8%. And the accuracy in reading humidity is 89.8% with a difference of 11%.]]>

<![CDATA[The Covid-19 virus is currently rampant in the world, especially in Indonesia, the spread of the Covid-19 virus is getting faster and wider. Even the spike in cases was unpredictable. Since entering Indonesia last March. In an effort to prevent it, almost every area carries out a body temperature test and sprays disinfectants on people who enter the area. This study aims to produce an automatic disinfectant sprayer and test its effectiveness. The method used is the data collection analysis method by testing the product. This tool uses ultrasonic sensors as object detectors, MLX 90614 sensors as temperature readers and Arduino Uno R3 as controllers. The output uses a Relay module that is connected to a Water Pump that sprays disinfectant liquid through a spray mist. This tool is effective in its manufacture and is able to detect objects in the area of ​​​​the disinfectant booth. The results of the study found that the level of accuracy of the MLX 90614 sensor which was calibrated with the Thermogan measuring instrument had an accuracy of reading the temperature of 98.8% with a difference of 1.16%.]]>

<![CDATA[The wire-mesh sensor is an intrusive sensor device that uses for generating 2-dimensional (2D) images of fluid flow. Sensors made of 2 layers copper wires, transmitter, and receiver, that perpendicular each other. The wire-mesh sensor will directly to measure the value of inductance or capacitance at the crossing wire. There are 208 data measurements in 16 × 16 cylindrical wire-mesh sensors. All data measurement then processed by Python software to obtain a 2D image of the capacitance distribution. Experiment results show the inhomogeneous distribution of capacitance that occurs in the wire-mesh sensor. Three types of liquids, distilled water, tap water and salt solution, showed circular pattern of capacitance distribution, with the highest capacitance value being in the central area of the image, while at edge area has a lower capacitance value than the central area]]>

<![CDATA[Environmentally friendly problems have been widely studied in scientific journals, one of which is the use of gases that can damage the environment in a variety of cooling devices such as refrigerators and air conditioners (AC). In the past two decades, most of the refrigeration engines were still using Chloro Fluoro Carbons (CFC) gas, which had been researched in fact could damage the ozone layer. One alternative is to use freon gas to replace CFC gas as a component of air conditioning. Until now, CFC gas has been completely replaced by freon gas in the use of household appliances. But the use of this gas still has a bad side, especially for humans, when it inhaled in a certain amount can cause death. Therefore, in this study an air conditioning device with a main component was designed using thermoelectric TEC1-12706 which utilizes the Peltier effect in producing cold temperatures. This device is able to cooling a room with dimension 12 m2 in the interval of time 120 minutes to a temperature of 28.1 °C.]]>
