Aplikasi Rangkaian Pengali Tegangan Walton Cockcroft Dan Sensor Af-30 Pada Penjernih Udara Ruangan Otomatis

Air is very important for all the living being in this planet, therefore good quality of air has to be maintained. The air quality in our office environment is much decreasing nowadays, due to human behaviour and life style, such as smoking and in return reduces our health. This reasearch proposes to design an air purifer to increase air quality inside a room. The propose air purifier applies Walton Cockcroft voltage multiflier with voltage output 4000-5000 Vdc to separate carbonmonoxide (CO) from oxigen. This device will work as soon as smoke sensor AF-30 detects carbonmonoxide in the air. This carbonmonoxide detection will result analog signal as the input to the programmed microcontroller ATMega 8535. The output signal of microcontroller ATMega 8535 will activate relay switch circuit and in the end will activate DC Motor fan, voltage multiplier circuit and exhaust fan. The voltage multiplier circuit output is 4420 volt DC at the 13th stage, this high voltage will ionize carbonmonoxide (negatif ion) from oxigen (positif ion). After positif and negative ion get separated, negatif ion would be outed by DC fan to the purifier element, the negatif ion would be the residue and stayed inside the purifier. It is hoped that this device would help in increasing air quality in side office room

LITERASI MEDIA ISLAMI ANAK MENGGUNAKAN METODE “SATU ANAK SATU BUKU”

Literacy for early education students can be defined as the ability of reading and writing. This capability will increase if (1) facilities and (2) infrastructure are easily accessed, and (3) supported by the environment. The observation shows that those three factors are not available for children learning Al-Quran and Islam in Al-Ikhlas Masjid, especially Islamic media literacy. The community service was conducted in Al-Ikhlas Masjid to increase Islamic literacy for children using the method of "One Child One Book." Books and short version of Al-Quran were donated to encourage the children to enjoy reading and writing. This method was successful in increasing children's interest in reading shown by the enthusiasm of 14 children who came to participate in the activities.The Al-Ikhlas Masjid became crowded because the children came almost every evening to read and borrow books. Everyone was happy to read the books provided by the team. Therefore, the community service was considered successful in increasing Islamic literacy proven by an excellent reception from parents and children studying at Al-Ikhlas Masjid, and they are expecting further activities

The impact of Nodes Distance on Wireless Energy Transfer System

Wireless energy transfer (WET) reemerges as the method for transmitting electric power without the necessity to deal with cable losses and an aesthetically pleasing environment. The problem with WET is how to maintain magnetic induction as the distance gets further. This paper investigates the impact of nodes distance on the WET system. The experimental results show that the most effective distance among transmitter, nodes, and receiver are 4 cm. The measurement is taken with and without load. The without load application give that for node 1; the results are 6 V, 110 mA, and 2.85 mT for voltage, current, and magnetic flux, respectively. At the application of 2 nodes, the voltage is 6.8 V, the current is 0.124 mA, and the magnetic flux is 3.83 mT, and at three nodes installation, it is 7 V, 134 mA, and 3.83 mT. During the application of 3-Watt and 5-Watt lamp, at 4 cm distance, the power received is 1.66 W and 3.66 W at 3-Watt and 5-Watt lamp for one node, 1.84 W, and 3.84 for two nodes, and 1.93 W and 3.93 for three nodes. The experimental results show that the transmitted signal can be prolonged by installing nodes. Even though this study shows that 4 cm is the most effective, it is possible to increase up to 20 cm to power a 3-Watt lamp and 5-Watt lamp
