<![CDATA[AbstractDistribution transformer has a very crucial role on electrical power supply distribution system. In 1972, International Electrotechnical Commission (IEC) 354 claim if a transformer get a stable load on it’s identification power with ambient temperature 200C, transformer hot spot temperature will reach 980C and it’s lifetime became 20 years or 7300 days withnormal loss of life 0,0137% each day.Daily average ambient temperature in Pontianak is 300C, causing transformer’s load has to be adjust to avoid highloss of life. Distribution transformer which installed on feeder Raya 10 has 11 units operating with daily load 80% - 100%of identification power and 8 units with over 100% daily load of identification power. Base on research that has been done we’ve come to conclusion that transformer which operating in Pontianak should not gain 91% load of identification power cause will decreasing the transformer lifetime drasticly. Keywords: distribution transformer, loss of life, ambient temperature, load.]]>

<![CDATA[Lettuce cultivation (Lactuca sativa L.) in Indonesia until now still using the method of planting in open land that has many obstacles and requires a large enough land. The impact is the disruption of crop growth that affects the productivity and availability of land required. To overcome it can be applied a method of aeroponic cultivation of plants with a vertical system that avoids plants from pests and can save places for planting. Cultivation of plants with aeroponic system makes it easier for us to control the variables needed by lettuce plants such as temperature and humidity. The aim of this reasearch is to design the air and humidity control system in aeroponic media in the range needed by the lettuce plant, that is at a temperature of 25 oC to 28 oC and humidity in the range of 65% to 78%. For the measurement of ambient temperature and humidity of the environment can be selected sensor DHT11. DHT11 has a calibrated digital output, connected directly to the Atmega32P microcontroller in board Arduino Uno R3, and the driver as a switch for the pump and fan.When temperature >28oC then the pump will be turn on and when the humidity>79% then the fan will turn on, control systems work on-off. From the two media tested that is media A (with the controller) and media B (without the controller), Lettuce plants in media A grow with an average plant height increase of 1.6 cm and can beconsumed, while Lettuce plant in medium B grows with an average plant height increase of 0.42 cm and experiencing crop failure, with leaves withered, thus Lettuce on media A managed to grow well, while Lettuce on media B died on the 19th day, so that research with controlling device better than conventional planting.

<![CDATA[The different space of joint BTS would potentially create interference which could interfere the performance quality of an operator. Isolation denoted a value from each antenna which had common value of 30 dB. This minimum spacing calculation was used according to space isolation calculation. In case of frequency of 1710 up to 2170 Mhz, it was obtained that the minimum vertical spacing was 0.15 up to 0.19 meter, for frequency of 1710 up to 2170 Mhz, it was obtained that the minimum horizontal spacing was 0.63 up to 0.82 meter, for slant spacing obtained with isolation value was 71.436 dB. Spacing installation at BTS PAL 5 Jln Husin Hamsah, RT/RW 005/001, Kelurahan Paal Lima, Kecamatan Pontianak Barat was 4.5 meter for vertical spacing, 2 meter for horizontal spacing, and 71.436 dB which was more than 30 dB for slant isolation. Thus, the result obtained in the field showed antenna spacing at BTS PAL 5 Barat had met the standard for antenna isolation. Antenna with isolation value of <30 dB had to be adjusted toward installed antenna; extent spacing between one antenna to the others; adjust tilt of antenna in order to increase isolation value of antenna; adjust azimuth angle by getting it away from antenna that had been interfered so that the isolation value of the antenna met the standard. The receiving level of MS also had to be taken into account to measure the power of receiving signal of each MS from installed antenna, with Walfish-Ikegami method, it was obtained that the value of receiving power decreased upon spacing of 1km from antenna, so that there should be certain adjustments toward the height of the antenna. Key Words: Antenna isolation, space isolatioan calculation, joint BTS, quality of signal]]>
