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.

Motor Exhaust

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.

The use of electrical energy that is often encountered in households is leaving the house with the lights on, leaving electronic goods stuck in the socket, charging cell phones overnight and turning on the air conditioner when no one is around. This unwise behavior will result in a high increase in the use of electrical energy. To reduce this unwise behavior, a device will be made that functions as a switch to cut off electrical energy automatically when we leave the room. This tool uses an Arduino Uno microcontroller with a Passive Infrared Receiver sensor to flow electrical energy when we enter the room and cut off electrical energy when leaving the room. It can be concluded that the use of an automatic switch can reduce electrical energy consumption. Automatic switches with a delay of 20 seconds compared to conventional switches have a significant ratio of electrical energy consumption as indicated by the test results of a multiple ratio of 0.00 with a test level of less than 0.05. Using an automatic switch with a 20 second delay results in savings in electrical energy consumption of 48.76% of the electrical energy consumption using conventional switches.

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.

Technical Basis

When the ASME Code fatigue curves (S-N curves) are used in the assessment of high frequency cyclic stresses (such as those produced by flow-induced vibrations), the question arises as to the need for an E correction (i.e., multiplying the calculated cyclic stress by the ratio of the E value at the room temperature and the E value at the temperature used in the stress analysis). This question becomes significant for materials such as stainless steels when the two sets of S-N curves up to the 2007 Edition of the Code [1] are specified: i) the first curve covered the cyclic range of 10 to 106 cycles and specified an E value. This curve covered mostly the strain controlled fatigue data for which the correction for E is required. ii) The second curve covered the cyclic range of 106 to 1011 cycles and didn’t provide a specific E value. This curve covered mostly the load controlled fatigue test data for which the correction for E is not required since the stress was independent of E (stress was either P/A for axial loading or Mc/I for bending). However the 2010 and subsequently the 2013 Editions of the Code [2] combined the two curves into a single curve with a cycle range of 10 to 1011 cycles with E value specified at room temperature. This means that the E correction applies across the board for the entire cyclic range of 10 to 1011 cycles including the high cycle end where the test results are independent of E. The inclusion of the E correction for the high cycle fatigue range presents a problem for the evaluation of components with vibratory loading. The present paper describes the results of a thorough review of the past technical basis papers for the ASME Code S-N curves and examines the necessity for E correction at the high cycle end of the Code S-N curves for stainless steels.

Theoretical Results

Pure organic room temperature phosphorescence (RTP) and luminescence from nonconventional luminophores have gained increasing attention. However, it remains challenging to achieve efficient RTP from unorthodox luminophores, on account of the unsophisticated understanding of the emission mechanism. Here we propose a strategy to realize efficient RTP in nonconventional luminophores through incorporation of lone pairs together with clustering and effective electronic interactions. The former promotes spin-orbit coupling and boost the consequent intersystem crossing, whereas the latter narrows energy gaps and stabilizes the triplets, thus synergistically affording remarkable RTP. Experimental and theoretical results of urea and its derivatives verify the design rationale. Remarkably, RTP from thiourea solids with unprecedentedly high efficiency of up to 24.5% is obtained. Further control experiments testify the crucial role of through-space delocalization on the emission. These results would spur the future fabrication of nonconventional phosphors, and moreover should advance understanding of the underlying emission mechanism.<br>
