High concentration of Boron and Phosphorus elements are required in diffusion process during the fabrication of semiconductor devices such as diode and transistor based on Silicon On Insulator (SOI) wafer. Achieving high level of these elements’ concentration is the entry point for further research in the field of electronics. For this reason, the concentration of the both elements was tested by flowing Boron and Phosphorus gas with flow rate of 1.5 litre per minute into the Nitrogen furnace for 5 minutes towards the surface of the SOI wafer samples at temperatures of 880, 900 and 950 degrees Celsius. This test was carried out at Michiharu Tabe Laboratory, Research Institute of Electronics, Shizuoka University, Hamamatsu, Japan. Furthermore, the resistivity measurements of samples with Boron and Phosphorus doping were carried out. The results of resistivity were then converted to obtain the concentrations of Boron and Phosphorus on the surface of SOI wafer sample. From the concentration and temperature data, it is obtained the modelling of concentration to temperature function for Boron and Phosphorus. The modelling results show that there is a linear correlation between high concentrations of Boron and Phosphorus to temperature.

Sistem pengendalian suhu ruangan secara otomatis diyakini mampu memberikan penghematan tanpa mengurangi performansinya. Pengendalian suhu ruangan dilakukan dengan mengatur kecepatan putaran motor exhaust fan dengan SCR speed controller. Hal ini sangat diperlukan untuk menghemat pengeluaran listrik. Dalam mengkoneksikan antara sensor suhu dengan SCR speed controller diperlukan mikrokontroler Arduino Uno sebagai pengolah data keluaran dari sensor sehingga dapat mengendalikan speed controller 1 dengan keluaran tegangan 180 volt dan speed controller 2 dengan keluaran tegangan 200 volt. Alat ini cocok digunakan untuk mengatur suhu di ruangan tertutup agar selalu stabil. An automated room temperature control is a way to do savings without reducing its performance. The temperature control is done by adjusting the rotation speed of the exhaust fan motor using an SCR speed controller. This mechanism will give a great advantage on power usage reduction. To connect the temperature sensor with the SCR speed controller, an Arduino Uno microcontroller is used as a processor of the outputs from the sensor so it can control the 1st speed controller with 180 Volt and the 2nd speed controller with 200 Volt. This tool is suitable for maintaining the temperature of a closed room temperature.

Jamur tiram merupakan salah satu bahan makanan yang mempunyai kandungan gizi yang baik sehingga banyak masyarakat yang senang mengkonsumsinya. Hal ini menyebabkan usaha budidaya jamur tiram menjadi usaha menarik untuk dikembangkan. Jamur tiram akan tumbuh dengan baik pada suhu 22 - 28°C dan kelembaban 80 – 90% RH. Daerah Indonesia umumnya memiliki dua musim, yaitu musim hujan dan musim kemarau. Musim hujan berlangsung sekitar bulan November sampai April, curah hujan sangat tinggi, suhu udara relatif dingin, sekitar 24°-28°C pada siang hari dan 23°-26°C pada malam hari. Sedangkan musim kemarau umumnya berlangsung sekitar bulan Mei sampai Oktober, pada musim ini suhu udara cenderung cukup panas, yaitu sekitar 28°-34°C pada siang hari dan sekitar 21°-25°C pada malam hari. Temperatur udara pada siang hari saat musim kemarau inilah yang jadi masalah bagi pembudidaya jamur tiram. Program IbM (Iptek bagi Masyarakat) ini bertujuan untuk dapat mengkondisikan udara pada saat puncak musim kemarau agar dapat tetap terjaga pada kelembaban 80-90% dan temperatur 22-280 C. Metode yang dipakai adalah dengan memasang sistem pengkondisi udara yang terdiri dari nozle pengkabutan dan exhaust fan. Nozzle kabut berfungsi menyemburkan kabut untuk menaikkan kelembaban dan menurunkan temperatur, sementara exhaust fan berfungsi untuk membuang udara panas keluar kumbung. Kabut dihasilkan oleh 8 nozzles yang mendapatkan suplai air dari pompa air 300 watt dengan tekanan minimal 3 bar. Operasi pompa diatur oleh sebuah mikrokontroller yang mendapatkan input dari sensor kelembaban dan suhu yang dipasang di dalam kumbung jamur. Oyster mushroom is one of the food ingredients that have good nutritional content so that many people are happy to consume it. This makes the cultivation of oyster mushrooms becomes an interesting business to be developed. Oyster mushrooms will grow well at 22 - 28 ° C and 80 - 90% RH. Indonesia generally has two seasons, the rainy season and the dry season. The rainy season lasts between November to April, it has very high rainfall and relatively cool air temperature, around 24 ° -28 ° C during the day and 23 ° -26 ° C at night. Meanwhile, the dry season generally takes from May to October. In this season, the air temperature tends to be quite hot, which is about 28 ° -34 ° C during the day and around 21° -25 ° C at night. Air temperature during the dry season is a problem for oyster mushroom cultivators. This IbM program aims to be able to condition the air during the peak of the dry season in order to stay awake at 80-90% humidity and temperature 22-280 C. The applied method is to install an air conditioning system which consists of a mist nozzle and an exhaust fan. The mist nozzle serves to spray mist to increase the humidity and decrease the temperature, while the exhaust fan has a function to remove the hot air out of the mushroom room. The mist is produced by 8 nozzles which get water supply from 300 watt water pump with minimum pressure 3 bar. Pump operation is controlled by a microcontroller that get input from humidity and temperature sensor that mounted inside the growing mushroom room.

The need for reliable tools or machines has become a priority for everyone today, from tools used for personal use to tools or machines used for industry. State Electricity Enterprise (PLN) also needs reliable tools to monitor assets with high accuracy. One of the components to monitor the load on the network is a recloser. This component is often disconnected from the dispatcher control center so that it cannot be monitored. One of the causes of the disconnection between the recloser device and the control center is the occurrence of excessive heat in the recloser box panel which causes the components inside to overheat. The automatic cooling system in the recloser panel box aims to maintain the temperature inside the panel box to be able to provide maximum component performance. In this study, an application was developed that was able to monitor temperature readings in the recloser panel box and monitor the condition of the cooling system inside. From the test results, it is known that the temperature conditions inside the panel box are monitored to be stable, even though outside the panel box there is an excessive temperature spike.

In this modern era, the community (especially in urban areas) can get enough water supply from PDAM (Regional Water Supply Company). In other cases, not all houses in the village or needs like farms or fields can get enough water supply. For example, technology for distributing and monitoring water from tanks to farms or agriculture is also still conventional and limited by visiting and opening water taps at the location. For this reason, we need a control system that can monitor and control the volume of water in several tanks through one application display on smartphones such as Telegram. Using NodeMCU ESP8266 as the microcontroller base, the ultrasonic sensor as a water volume measuring sensor, and the mini water pump, the condition of the water volume and all the changes can always be monitored through notifications on Telegram. In addition, the system can also be controlled automatically or manually through the commands provided on the telegram. We use Telegram as a control system, and monitoring the volume of water tanks in more than one tank can be the right alternative in designing a water tank control system. One Telegram bot can monitor and control more than one tank, where every tank has an individual ESP8266 module and ultrasonic sensor installed.

An electric vehicle uses increasing in Indonesia. Airport services are also advancing the development of electric cars on Baggage Towing Tractors (BTT). BTT is used to attract aircraft baggage to the terminal baggage queue. BTT uses an electric engine as a driving force and an 80V battery as a voltage source. If the BTT battery is not managed correctly, then it is an effect on the battery life. This battery is prone to over-voltage, under-voltage, and over-heat. The project is necessary to develop a system that makes it easier for users to monitor battery performance and technicians during maintenance. The concept of this system is based on an android application. This application will provide real-time information about battery voltage, temperature, and humidity through Firebase Database. The data received by sensors is sent to the database via a microcontroller, which is connected to a Wi-Fi network. The android application will access the database and display data in real-time by ignoring previous data. This system is designed for users to determine the condition of the BTT battery that will be used. The system was tested to evaluate measurement accuracy and speed of updating data. From the test result, the level of accuracy system is around 97%, and it’s rated as working optimally.

This article compares the voltage drop on Lead-acid and Lithium-ion batteries used as an energy source for electric scooters. An experiment was conducted with five electric scooter users weighing 60.25 Kg, 70.60 Kg, 83.20 Kg, 95.40 Kg, and 103.75 kg to obtain data on voltage drop. Each user of this electric scooter carried out three experiments by circling about 1.07 Km at the Politeknik Negeri Bali area. This study proves that the voltage drop on the Lead-acid and Lithium-Ion batteries has a linear relationship to the weight of an electric scooter user with a 36V 400-watt BLDC motor load. The linear equation has an intercept value of -1.36766 and a slope value of 0.04791 for the Lead-acid battery. In contrast, the linear equation has an intercept value of -2.47064 and a slope value of 0.05417 for Lithium ion batteries. The average voltage drop across lead acid is 25% higher than that across Lithium-ion
