Abstract

ABSTRACT Technology based payment system named radio frequency identification (RFID) made as a replacement for payment system on Ayani Mega Mall which it is still manually-operationed. This manual system considered lack on effectiveness in timing use so it makes long queue when customer will pay at cashier. RFID is an identified method using radio wave as transmission media in detecting data. With RFID, the payment will be more efficient so it need less time than manual. RFID consist of two tools, which are transponder/tag and reader, on this system every costumer has different tag and id number. Every tag has registered on database system on software; software is important on this system. The data on this application consist of data of the tag owner and customer balance. This payment system application using Delphi 7.0, the data is taken from database when doing payment. Customer just asked to put the tag near to the reader, so the reader will detect data on tag. It just need about 5,5 centimeters between tag and reader, if more than 5,5 cm, the reader could not detect tag. RFID reader has 13,56 MHz for its radio wave frequency.

Abstract

Dalam Skripsi ini telah dilakukan analisis tegangan lebih transien impuls persegi pada ujung saluran transmisi akibat pengaruh beban R, L, dan C secara eksperimental. Hasil Penelitian menunjukan bahwa, untuk beban bersifat induktif dan kapasitif, tegangan pada ujung saluran transmisi dapat mencapai dua kali besar tegangan gelombang datang. Besar L dan C hanya berpengaruh kepada waktu kenaikan gelombang. Untuk beban bersifat resistif, besar R berpengaruh terhadap tegangan pada ujung saluran. Jika beban R lebih besar daripada impedansi surja (R>Z) maka tegangan lebih pada ujung saluran lebih besar dari besar tegangan gelombang datang. Jika beban resistif lebih kecil atau sama dengan impedansi surja (R≤Z) tegangan pada ujung saluran tidak akan lebih besar dari tegangan gelombang datang.   Kata kunci : Eksperimental, Gelombang Berjalan Kawat Transmisi, Tegangan Lebih Transien.

Abstract

ABSTRACT The need for electricity Pontianak continued to rise every year. The fact requires the development and good planning in electric power systems. One of the components in the power system needs to be improved is the power transformer. This is needed because the power transformer plays an important role in distributing electricity to consumers. Based on peak load feeders data from  PT. PLN (Persero) Parit Baru substation Branch Pontianak, it has described the rapid development of load capacity. This resulted in the need for further studies to predict the load at the substation. Increasing the capacity of the power transformer in the substation Parit Baru can be done by calculating the peak load prediction for the current and future. Studies needed to increase the peak load is used to calculate the approximate capacity of power transformer in the substation by using an exponential regression function which has the smallest standard error as compared with the linear regression function. Based on the results of the approximate calculation of the load and by SPLN17A / 79,  the peak load in 2016 amounted to 30.904 MVA happened already past capacity power transformer substation in Parit Baru and that should be anticipated with the correct solution. Results to be achieved in 2016 is to increase the capacity of power transformer in the Parit Baru substation.   Keywords: Substation, Power Transformers, Capacity, Peak Load

Abstract

ABSTRACT Monitoring  the consumption of  fuel  and the temperature on a generator is important  to retain a backup power source of the generator without running out of fuel or causing a high temperature in the generator. The design of the monitoring system could detect changes in the condition of the fuel and temperature simultaneously when the generator is in operation. This monitoring system process used an ultrasonic censor to detect the consumption of fuel that is attached to the oil tank and a temperature censor to detect temperature changes in the generator mounted on the body of the generator. The ultrasonic censor output voltage and temperature censor were the converted by the Analog To Digital (ADC) Internal microcontroller ATMega16. This system design was divided into 10  scale percentage unit (%) for the consumption of fuel  and a celsius unit (° C) of the temperature measurement for the changes of the temperature of the generator. The data  detected by the censors instalated would be processed by the microcontroller and the sent through Wavecom Fastrack M1206B modem to celluler phone in the form of a text messageof the  short message service (SMS),  sent through Wireless Radio Telemetry Kit 915MHz to a computer/laptop which was shown ina graphical form,  displaying the monitored data by using the 16 x 4 LCD display.

Abstract

One of building sector which is developing in Pontianak city is the raise of hotels in the center city. Hotel needs large enough electric energy. It’s proved by the used of transformator capacity, till 1250 KVA and the use of genset as big as 1000 KVA. This must be followed by a good and efficient electric distribution to get high electric energy supply. The hotel building that become a research object  in Pontianak city is located in Jl. Teuku umar is Golden Tulip. It stand on 11 floors that consume big enough electric energy. This hotel has had a good distribution system, effectif and efficient instalation such as balance dividing load, safe and standart electric instalation, PUIL 2000 and professional  electric system to minimize the waste of electric energy while distribution because of the loses power. Based on accounting result, data analiz, dividing load and electric instalation in hotel Golden Tulip Pontianak must be divided and categoried spread evenly between stand by load and unstand by load to get the balance dividing load, otherwise on the measuring result in the basemant floor until five floor, there is unbalance load that cause by the unspread evenly load categories to get the safe MCB result, MCCB and grounding cabel is different with planning result. This is happened because 1 feeder pull for 3 different  panel in basemant floor, 1st floor  and 2nd floor. Same cases with the 3rd floor panel, 4th floor and 5th floor only need 1 feeder  pull. Based on planning analize result for the effeciency distribution of electric power can be done by 1 feeder  pull directly to each panel / floor.   Keyword : Load dividing, electric instalation, PUIL 2000.
