The aim of this research is to provide the design and implementation of a monitoring system which is able to detect rain and temperature based on real time sensor. This system focuses on the results of raindrop detection sensor as a rain detector and NTC thermistor as a temperature detector. Both of the sensors have an analog output. Therefore, they require an Analog Data Converter (ADC) to measure. Several tools are used to build this monitoring system, including microcontroller Arduino NANO for input sensor value readings, data processing and programming. Real Time Clock (RTC) is used to provide time information when the sensor works, as well as the telemetry as the wireless communication device. An interface based on Graphical User Interface (GUI) using JAVA as the monitoring software which can be operated on a PC or laptop. Based on the analysis and evaluation, this tool can detect rain and temperatures in real time.

Sebuah sistem kendali berbeda pada navigasi robot tank diperkenalkan pada penelitian ini. Umumnya sistem kendali navigasi robot tank dikendalikan meggunakan remot kontrol atau joystick dan beberapa perangkat pengontrolan robot lainya. Pengontrolan navigasi robot tank bertujuan untuk dapat mengendalikan pergerakan robot agar dapat berjalan maju, mundur, berbelok ke kiri dan ke kanan. Pada penelitian ini, pengontrolan navigasi robot dilakukan berdasarkan gerakan tangan manusia. Sebuah sarung tangan yang dilengkapi sensor accelerometer ADXL335 didesain untuk dapat mendeteksi setiap bentuk gerakan tangan. Pendeteksian gerakan tangan didasarkan pada pembacaan orientasi axis X dan Y acceleometer. Gerakan tangan ini kemudian diinput pada mikrokontroler Arduino Nano dan ditransmisikan melalui nRF24L01 2.4GHz. Hasil pendeteksian gerak kemudian diterima dan diolah pada mikrokontroler Arduino Mega yang terdapat pada robot tank. Selanjutnya, hasil pendeteksian gerakan tangan ini dipetakan dalam beberapa bagian pengontrolan, agar sesuai dengan pola pengontrolan navigasi robot tank. Hasil penelitian ini menunjukan bahwa sebuah sistem pengontrolan navigasi robot tank berdasarkan gerakan tangan dapat diimplementasikan dan diaplikasikan secara riil, sehingga dapat memberikan pengalaman baru dalam berinteraksi dengan robot.

The electric power system consists of various components, ranging from the components of generation, transmission, and distribution. The systems are quite expensive, so that excellent, reliable, and economic protection is needed to avoid internal and external faults.Â The faults can trigger damage to components, especially on the main transformers in the Power Plant Geothermal Unit 4 of the Kamojang area managed by PT Pertamina Geothermal Energy. Disturbances that occur in the main transformers of various types so that the primary protection needed in the transformer is a differential relay to protect to avoid interference that occurs. This study discusses the comparison of theoretical differential relay calculation calculations with actual differential relay setting data in the Kamojang Unit 4 Geothermal Power Plant and simulates with ETAP 12.6 software. The problem that occurs in the main transformer of the Geothermal Power Unit Unit 4 Kamojang area is the difference in the slope 1 of the actual setting data with a mathematical calculation that is the actual setting data of 40% and the numerical calculation data worth 8.5%. Please note that the minimum slope one limit is 5%. PT Pertamina Geothermal Energy made slope one changes, so that differential relays are not too sensitive to the interference current that occurs within the protection zone of differential relays.

Generator or alternator is a device that has a function to convert or transformmechanic energy to electricity. Electricity conversion need process with givingstrengthening with excitation current to coil magnetic field that placed on sync generator. Excitation current that flows on magnetic field coil will cause magnetic flux. Generator sync on PLTU unit 3 and 4 PJB UP Gresik use excitation system with excitation static type, this type of excitation it uses carbon brush as a media to conduct excitation current, this excitation system use the output of sync generator. In reality this excitation current which exist on PLTU unit 3 and 4 have to should always be taken care so the system can operate normally and commonly the fault that happened is under excitation and over excitation so it can be prevent. Step taken to avoid damaging the generator sync that caused by excitation current, steps that have to be taken are understanding thecharacteristic of system excitation setting, anchor current, voltage generator, and loading. The value of loading is very affecting the value of excitation current that injected toÂ generator, the purpose of this process of excitation current injection is to maintain the stability from sync generator voltage so that the condition is staying on its normal condition.

In the system of electricity power, either thermal or electric failure often takes place. In order to prevent such failure, isolator testing towards the power transformer is needed. A mineral oil Nynas Nitro Libra was used as the research subject, in which it was compared to the other oil types, involving new oil, in-use oil, and used crude oil. The method used was testing throughout the colour, water content, and breakdown voltage. Colour testing was conducted by comparing between used oil and typical oil, whereas water content was conducted by mixing chemical ingredients which were Solvent Xylol and toluene, followed by 100Â°C heating process within 3 hours and condenser cooling down until the moisture dropped down the trap, finished by 6 times breakdown voltage test through environment temperature. The testing result shows that crude oil indicates D 8,0 (black colour), with moisture content TRACE (0,2%) which is 4 ppm. The value of 6-time breakdown voltage test in the temperature of 22Â°C indicates: 09.4 KV, 09.1 kV, 09.2 kV, 09.6 kV, 09.5 kV, 12.0 kV with dielectric power 3.92 kV/mm.

The development of science and technology is increasing every day, especially in the field of electronics and control systems. This is marked by the rapid progress that has occurred with the creation of increasingly sophisticated electronic devices and all systems have gone from conventional to automatic. Many benefits are obtained from the rapid development in the field of electronics and control systems including being able to assist humans in completing their tasks, increasing human productivity, and increasing the level of effectiveness in doing work.
