Fans are electronic equipment that are often found in Indonesia, but fan use is generally still used manually. This can cause the use of fans to be ineffective, and again humans must approach the fan in regulating the fan speed according to room temperature and adjusting the fan direction that is right for use. The purpose of this research is to innovate conventional fans into automatic fans to make it easier and more comfortable for humans to operate. This research method is to explain the design of hardware and software as well as the exposure of the experimental tools. The results of this study are that the fan automatically selects the fan speed according to the temperature read by the DHT11 sensor, and if the read temperature exceeds 350C, the system will spray water vapor through a 12V DC pump and stop if the temperature read is below 350C, then the fan will turn on. On / off automatically according to the presence of people around the fan through the PIR sensor, the temperature indicator and the presence of people are displayed on the 16X2 LCD, then for the fan in terms of turning right-left and spraying perfume can be controlled from a distance of 7 meters via IR remote. Where all these systems are controlled via a microcontroller in the form of ARDUINO UNO

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.

In general, the control of using electronic equipment in the classroom manually. Sometimes lecturers or students forget to turn off electronic equipment after the class so that there is a waste of electrical energy use. Application of automation of using electronic equipment is one solution to overcome these problems so that electrical energy becomes more efficient. This study designed a prototype of an automation system for electrical equipment in the classroom, namely lights, fans, and projectors. This system was also to turn off the electricity when nobody was in the class. The automation system controls the use of electrical energy in devices in the classroom through on-off control of the electrical network components connected to each device. In this design, the PIR sensor can detect the presence of people up to a distance of 7 meters. The Arduino Uno controller activates the lights in the class when the LDR Sensor detects a light intensity of less than 200 Lux. Then, the fan is active when the LM35 sensor detects the temperature in the class above 28oC. The FC-04 sensor detects the sound of clapping for control of projector ignition by the controller.

Equipment Control

Electronic equipment is a daily necessity in human life, but not infrequently we use electronic equipment excessively or ineffectively and the main problem is the factor of forgetting and being lazy to turn off electronic equipment. This makes wasteful use of electricity so that the costs charged are greater and there is the greatest risk of contact currents causing fire if we neglect to use lighting. Therefore, the author tries to make a control device for electronic equipment with voice commands connected to Bluetooth on a smartphone so that users can give commands to activate or deactivate electronic equipment with voice commands. The research method used is direct observation of the selected object, namely the author's house, and conducting literature studies related to the Arduino microcontroller. The Arduino microcontroller acts as the main controller connected to the relay module and the relay module connected to the power plug. In addition, Arduino is also connected to Bluetooth as a place to process incoming commands. The purpose of this research is to produce a tool that can make it easier to turn on or turn off electronic equipment with voice commands via an Android smartphone by utilizing an Arduino-based Bluetooth connection.

In cotton seeds the radicle has 12% moisture content which makes it possible to prepare freeze-fracture replicas without fixation or cryoprotection. For this study we have examined replicas of unfixed radicle tissue fractured at room temperature to obtain data on organelle and membrane structure.Excised radicles from seeds of cotton (Gossyplum hirsutum L. M-8) were fractured at room temperature along the longitudinal axis. The fracture was initiated by spliting the basal end of the excised radicle with a razor. This procedure produced a fracture through the tissue along an unknown fracture plane. The warm fractured radicle halves were placed on a thin film of 100% glycerol on a flat brass cap with fracture surface up. The cap was rapidly plunged into liquid nitrogen and transferred to a freeze- etch unit. The sample was etched for 3 min at -95°C to remove any condensed water vapor and then cooled to -150°C for platinum/carbon evaporation.

This research aims to create a Reosquido desalination tool for evaporation methods using a microcontroller. This tool can control the temperature to speed up the evaporation process in producing fresh water. The method applied to Reosquido desalination uses Evaporation. The first process before evaporation is the detection of temperature in sea water that will be heated using an element heater. The second process of temperature measurement is to turn off and turn on the Arduino Uno controlled heater, when the temperature is less than 80 ° then the heater is on. The third process is evaporation during temperatures between 80 ° to 100 °, evaporation water sticks to the glass roof which is designed by pyramid. Evaporated water that flows into the reservoir is detected by its solubility TDS value. The fourth process is heater off when the temperature is more than 100 °. Based on the results of the testing, the desalination process using a microcontroller controlled heater can speed up the time up to 55% of the previous desalination process tool, namely manual desalination prsoes without using the heater element controlled by the temperature and controlled by a microcontroller which takes 9 hours. Produces fresh water as much as 30ml from 3000ml of sea water, so that it can be compared to 1: 100.

Abstract There are two kinds of water in CuSO4·5H2O differing by their binding in the crystal. The oxygen of four water molecules is bonded to the copper ion, that of the fifth molecule is hydrogen bonded. It is shown that the D/H ratios of these two kinds of water differ by 5.7%, the light isotope being enriched in the water molecules coordinated with the copper ion. The results show that there is no exchange of the hydrogen isotopes during the time needed for dehydration at room temperature which takes several days. The assumption has been confirmed that the water coordinated with the copper ion leaves the crystal first on dehydration at temperatures below 50 °C. Additional measurements of the separation factor for the hydrogen isotopes between water vapor and copper sulfate solutions allow conclusions on the fractionation of the hydrogen isotopes between bulk water and hydration water in aqueous solutions.

AbstractHfO2-based materials are the leading candidates to replace SiO2 as the gate dielectric in Si-based metal-oxide-semiconductor filed-effect transistors. The ubiquitous presence of water vapor in the environments to which the dielectric films are exposed (e.g. in environmental air) leads to questions about how water could affect the properties of the dielectric/Si structures. In order to investigate this topic, HfO2/SiO2/Si(001) thin film structures were exposed at room temperature to water vapor isotopically enriched in 2H and 18O followed by quantification and profiling of these nuclides by nuclear reaction analysis. We showed i) the formation of strongly bonded hydroxyls at the HfO2 surface; ii) room temperature migration of oxygen and water-derived oxygenous species through the HfO2 films, indicating that HfO2 is a weak diffusion barrier for these oxidizing species; iii) hydrogenous, water-derived species attachment to the SiO2 interlayer, resulting in detrimental hydrogenous defects therein. Consequences of these results to HfO2-based metal-oxide-semiconductor devices are discussed.
