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.

This research is about controlling the circulation of room temperature which is done automatically if the room temperature is cold then motor rotation speed so slowly and vice versa if the room temperature is hot then motor rotation speed will be faster. In this study controlling the circulation of the room temperature with the fan in the activation is made automatically that is equipped with LM 35 temperature sensor which is then controlled using Arduino Uno and can adjust the speed of rotation from the fan. The fan can work automatically so it can simplify the man who previously the fan activation process is done by humans. And also can be more efficient in energy consumption because the fan works at the necessary time only. From the test results obtained that the system can work well in accordance with the planning and the role of the sensor is very important that can affect the overall success rate that is after the adjustment between software and hardware is equal to 80% by conducting tests periodically.

The development of electronic technology has created an ease in doing work especially those that require a long time as an example is the chicken egg incubator technology. If carried out manually, the chicken farmer must manually transfer the eggs, monitor the temperature set by the hour or set the expected temperature by experimenting many times. By using an automatic temperature controller, the farmer only needs one time to put the egg and put the sensor in the egg incubator. This study will discuss hardware and software which includes how to design a control device on a manually-controlled egg incubator for automatic control which consists of Arduino uno, a lamp as a heat source, a heat sensor, an LCD screen as an actual temperature sensor reader and fan as a room temperature stabilizer. From the results of testing the tool can function properly, ie the temperature is set to 38oC, if it exceeds the heat> 38oC, the fan will turn on to stabilize the temperature to 38oC.ABSTRAKPerkembangan teknologi elektronika telah menciptakan suatu kemudahan dalam melakukan pekerjaan terutama yang membutuhkan waktu yang lama sebagai contoh adalah teknologi penetas telur ayam. Jika dilaksanakan secara manual maka peternak ayam harus melakukan pemindahan telur secara manual, memantau keadaan suhu yang ditetapkan per jam atau mengatur suhu yang diharapkan dengan melakukan percobaan berkali-kali. Dengan menggunakan alat pengatur suhu otomatis maka peternak hanya memerlukan waktu sekali saja yaitu meletakkan telur dan meletakkan sensor dalam inkubator telur. Penelitian ini akan membahas tentang perangkat keras dan perangkat lunak yang meliputi Bagaimana merancang alat kontrol pada inkubator penetas telur yang terbuat secara manual kontrolnya menjadi kontrol otomatis yang terdiri dari Arduino uno, lampu sebagai sumber panas, sensor panas, layar LCD sebagai pembaca sensor suhu aktual dan kipas sebagai penstabil suhu ruangan. Dari hasil pengujian alat dapat berfungsi dengan baik yaitu suhu dibuat set point 38oC, jika melebihi panasnya > 38oC maka kipas akan hidup untuk menstabilkan suhu menjadi 38oC. Kata Kunci : perancangan; sensor suhu; arduino; penetas telur ayam

This work presents a study related to the grain refinement of an aluminum A2618 alloy achieved by High-Pressure Torsion (HPT) known as a process of Severe Plastic Deformation (SPD). The HPT is conducted on disks of the alloy under an applied pressure of 6 GPa for 1 and 5 turns with a rotation speed of 1 rpm at room temperature. The HPT processing leads to microstructural refinement with an average grain size of ~250 nm at a saturation level after 5 turns. Gradual increases in hardness are observed from the beginning of straining up to a saturation level. This study thus suggests that hardening due to grain refinement is attained by the HPT processing of the A2618 alloy at room temperature.

Abstract An integrated mixing/reaction micro flow cell which consists of a sample/reagent mixing channel, a visible port and a reaction chamber was designed, fabricated and tested. A micro cone hole array of macro porous Si was employed for reagent injection part. A visible light transparent PDMS slab was used as the visible port. A Ti-Pt thin film heater and a p-n junction diode temperature sensor were integrated on the reaction chamber to realize feedback temperature control. Uniform mixing and precise temperature control were realized by the fabricated micro flow cell. The striate and simple microchannel structure of the micro flow cell is suitable for multiplexed micro reactor for chemical and biochemical applications.

Lately, there are frequent fires caused by human factors. Because we cannot predict the process of fire in advance. And the delay in knowing the occurrence of a fire is very fatal to the safety of human life and property. With advances in technology, we can overcome fires by making early fire detection devices. With the presence of temperature and smoke detectors, we can detect fires as early as possible and be delivered quickly via alarms and SMS gateways. The main component of this fire detector is the Arduino Uno. This Arduino uno acts as the brain of the fire detection device. This tool works based on the detection of the temperature condition by the DHT11 temperature sensor, which is when the temperature is above normal, an alert notification will be sent via the SMS gateway and so will the MQ2 smoke and the buzzer will sound as a warning alarm.
