In this paper, a simplified zonal model for the evaluation of the spatial distribution of the air temperature in a thermal zone is presented. This model, in which the air flow is caused only by buoyancy forces, is implemented in ALMABuild. The model is used for the analysis of the effect of the temperature sensor positioning on the control system behaviour and on the indoor comfort conditions. This analysis is performed considering a multi-zone building composed by three offices, focusing the evaluation to the central one. The office is heated by means of a radiator in which the hot water flow rate is varied by a valve controlled via a room temperature sensor. By means of numerical simulations, indoor comfort conditions, energy consumptions and control system response are evaluated for three different sensor positions (far from the radiator, in the middle of the office, close to the radiator), two radiator sizes (one obtained by imposing a high supply water temperature, 80 °C, the other a low supply temperature, 60 °C) and two control strategies (weather compensation and fast restart). The results presented in this study and demonstrate how complete dynamic energy simulation tools can provide to the designer important information, like the room temperature sensor position that should be close to the emitter and far from cold external walls, for the optimal design of HVAC systems.

The use of electricity in offices has been considered too wasteful. This is caused by human negligence in controlling their use. For this reason, this research was carried out as an effort to find the right method to reduce the high electricity consumption in offices. This research was conducted in the STTAL classroom, Bumimoro, Surabaya. From the results of the calculation, the total heat load in the classroom is 32,048.3 BTU or ± 4 PK. Total installed AC capacity is only 2 PK. This automation tool is a system that works automatically to regulate the use of electrical equipment based on parameters that have been determined in a program such as the presence or absence of humans, the level of light intensity and room temperature. Data collection is carried out for 6 days in the classroom, 3 days without tools and 3 days using the automation tool. Furthermore, the data is compared to the graph and the savings are calculated. The result, on day 1 is 56.11%, days 2 and 3 are 10.26% and the average savings for the 6-day trial is 33.43%. All data is recorded automatically on a micro sdcard and information about the amount of electricity consumption and the ON / OFF feature of electrical equipment can also be accessed via a smartphone with a wifi network so that users will find it easier to monitor the use of electrical equipment in the classroom.Keywords: electricity waste, heat load, automation system, electricity monitoring, electricity savings.

Sarang walet merupakan tempat memproduksi air liur burung walet yang telah mengeras. Dalam pembuatan sarang walet harus memiliki kriteria-kriteria. Beberapa kriteria tersebut adalah suhu ruangan walet idealnya adalah 26-29 derajat celcius. Kelembaban udara juga berpengaruh terhadap sarang walet. Biasanya untuk mengatasi hal ini terdapat kolam air untuk menampung air pada ruangan. Air yang ada pada kolam tersebut di gunakan untuk mengatur kelembaban udara. Sehingga akan menjadi mirip seperti goa pada umum nya. Tingkat kelembaban dari 70 sampai 90 derajat celcius. Pada Intensitas cahaya 0 lux (gelap total) adalah intensitas cahaya yang disukai oleh Burung Walet untuk bersarang. Untuk bisa mendapatkan suhu dan kelembaban ideal diperlukan system automatis dalam mengontrol suhu dan kelembaban secara realtime. Dengan system automatisasi yang di atur melalui mikrokontroller menggunakan metode Fuzzy Sugeno untuk menghasilkan puteran air pada keran sehingga mempermudah kontrol ruang sarang walet dan juga data suhu serta kelembaban yang di kirim ke database untuk mempermudah monitoring suhu dan kelembaban dari website. Hasilnya adalah dengan penggunaan sistem kontrol suhu dan kelembaban menggunakan metode fuzzy Sugeno didapatkan hasil dengan 3 parameter yaitu suhu, kelembaban dan cahaya adalah 61.11%, sedangkan dengan 2 parameter yaitu suhu dan kelembaban adalah 39.29% dari 18x percobaan. Kata Kunci—Microcontroller, Arduino, Fuzzy Sugeno, IoTSwallow's nest is a place to produce hardened swallow birds' saliva. In making swallow nests must have criteria. Some of these criteria are the ideal walet room temperature is 26-29 degrees Celsius. Humidity also affects swallow's nest. Usually to overcome this there is a pool of water to hold water in the room. The water in the pool is used to regulate the humidity of the air. So it will be like a cave in general. Humidity levels from 70 to 90 degrees Celsius. At 0 Lux (total dark) light intensity is the intensity of light favored by Swallow for nesting. To be able to get the ideal temperature and humidity needed an automatic system to control temperature and humidity in real time. With the automation system that is set through a microcontroller using the Fuzzy Sugeno method to produce water spin on the tap making it easier to control swallow nest space and temperature and humidity data sent to the database to facilitate monitoring of temperature and humidity from the website. The result is the use of a temperature and humidity control system using the Sugeno fuzzy method obtained results with 3 parameters namely temperature, humidity and light is 61.11%, while with 2 parameters namely temperature and humidity is 39.29% from 18x experiments. Keywords—Microcontroller, Arduino, Fuzzy Sugeno, IoT

Currently, many electronic devices use the energy source from the solar cell which is stored in a battery. The battery is a portable, rechargeable power source. Solar energy is very suitable when converted to electrical energy because the amount of sunlight is infinite even though there is a period of time between sunrise and sunset. Converting solar energy to electrical energy requires a solar cell. One method that can be done is using the buck boost converter method with solar cell sources to create a battery charging control system. The Buck Boost Converter method was chosen because it can stabilize the output voltage from the solar cell when the weather is uncertain. If the light intensity of the sunlight is dim, the output voltage of the panel will also be low, then the converter will be in boost mode to increase the voltage level, on the other hand, if the light intensity of the panel output voltage will also be high, the converter will be in buck mode to lower the voltage level. The output voltage of this control system is maintained according to the battery charging voltage standard, which is 14 volts DC.
