<![CDATA[Increased population growth, economy and insfrastructure development, especially the construction of airports in Kulon Progo district indirectly impact on power availability. An Increase electric load in each year will affect the capacity of the power transformer at the 150 KV Wates substasion. With increasing electric load it will be the greater the electrical load borne by teh power transformator, so to prevent the occurence of overload, it is necesarry to eavaluate the power transformer capability by doing electric load prediction. In this reseacrh, the method used is trend analysis. For power transformer-I use exponential trend with MAPE value of 2,91% obtained estimate of load in year 2019 equal to 25,74 MVA where loading already exceed 80% While power transformer-II using the quadratic trend with MAPE of 1,19% obtained by the estimated load in 2025 of 52,29 MVA, after the addition of a special load plan, obtained load estimation in 2019 has reached 80%. So that in the year 2019 has been done addition of new power transformer, and in year 2024 can be done uprating on power transformer-I.]]>

<![CDATA[The high demand and limited availability of meat meat on the market, making the price of meat to be expensive, and more and more traders are mixing meat rotten meat into fresh meat. To avoid the risk, the public as consumers must beware and know the characteristics of rotten meat and the difference with the fresh meat. This research developed a tool detection fresh meat using RGB color sensor TCS3200-DB. Instrument works by measuring the composition of the RGB color in meat is identified and compared with the composition of the reference RGB color of fresh meat. The study begins by taking the composition of the RGB color of fresh meat samples as reference. RGB color composition is then recorded in the main program listing in the microcontroller. The instrument works by comparing the RGB color composition in meat detected by the reference RGB color composition. The microcontroller will determine the power of RGB color values ​​identified meat and then display it via an LCD. The results of this study indicate that fresh meat, G and B values ​​are closer to each other, respectively 3-38 and 3-29 to 4-27 and 4-25 G and for B the only difference being the value of R, which is the largest value of R is 58.]]>

<![CDATA[The high demand and limited availability meat in the market cause the pricesto be expensive, and increasingly traders that rotten the meat mixinto the fresh meat. To avoidthe risk, people should know the characteristics ofrotten meat and fresh. This research was development of previous research that develops a to olto identification the fresh meat and rotten with RGB color sensor.This research developed a to olto identification fresh meat and rotten using a digital pH meter senso rbased on value of acidic, basic, or neutral. pH meter works based on pH sensor, theg lass electrode. Digital pH meter works by comparing the potential difference at the sensor electrode with Hions at the meat. By using Op-Amp as a voltage amplifier with higher input impedance, then it can be display a signal voltage(mV) that converted to digital format byt he ADC(Analog to Digital Converter) that it can be displayed and read able on the LCD screen.acidic]]>

<![CDATA[PLN main source of power supply from PLN is very influential on electricity supply for the community. Electrical energy from PLN sometimes often occur blackouts. The need for reliable power supply is indispensable to residential consumers, especially in home industries. From these problems, this research is conducted to realize the control system used to transition the power supply with the main power supply from PLN and backup power supply from Uninterruptible power supply (UPS) and Genset. This study produces an automatic power supply transition which has two backup power supplies in the form of UPS and Genset. From the analysis of residential houses that have PLN 450 VA subscription, the system will work with a 12 Volt UPS battery at a current capacity of 28,125 A, and a capacity of Genset 800 VA. The automatic power supply transition system will instruct the UPS power supply to be connected when the PLN main supply is disconnected, after a UPS battery low will command the Genset for the starter, and when the generator is in stable condition the power supply will switch to the power supply Genset. At the time of PLN power supply source again available load will be transferred system to PLN source.]]>

<![CDATA[Distorting of energy of tension DC to AC used to support the social life of society. There by will arise an problems form of electric current from PLN desisted sudden and long time. The problems of course can be disregarded with the installation of power plant byself like generator AC or use the accumulator. Using of transistor energy of type MOSFET also used especially at final of switching showing optimal performance. This matter is showing with the temperature speed which relative lower and ideal performance temperature stability. The result of comparison of output power and efficiency of changer of energy of tension DC to AC with the transformator non-CT indicate that the appliance can only work 90% from maximal appliance ability. This problems because of accumulator use ably small current or standart.]]>
