Abstract

Nowadays the implementions of the transmission modulation techniques (high channel capacity) in optical fibres have been widely developed, one of the successful key factors of this system is the application of digital modulation techniques and the adjustment of modulation pattern. Modulation pattern of adjustment measures on the operational requirements of the system was made possible by the utilization of techniques Apol RZ-DPSK (Alternate Polarization Return-to-Zero Differential Phase Shift Keying). It is considered likely because it can reduce the effects of inter-channel non-linearity, noise and simultaneously demonstrates increasing system margins.

Abstract

High Capacity Base Transceiver Station (Hi-Cap BTS) is one kind of BTS which can hold increased traffic load rapidly because the numbers Trx at each sector can reach twelve Trx. Because of the fact, on the other hand the capacity of Hi-Cap BTS Trx are four times more than generally BTS. This paper discusses about the result and the analysis of Hi-Cap BTS implementation on BTS Muspasarseni with the first Trx configuration is 4/4/3 be modified to 8/6/3. This case uses four parameters such as traffic, Drop Call Rate (DCR), Handover Success Rate (HOSR) and Stand-alone Dedicated Control Channel (SDCCH) Success Rate (SDSR). Based on the analysis that has been performed, traffic rate at sector one, two and three are increased to 134%, 65%, 4% respectively. DCR rate at sector one, two and three are decreased to 54%, 39%, 18% respectively. HOSR rate at sector one, two and three are increased to 10%, 2,6%, 1,5% respectively. SDSR rate at sector one and two are increased to 2,3%, 2,8%, but SDSR rate at sector three is decreased to 1,2%. Keywords: BTS Hi-Cap, DCR, HOSR, SDSR

Abstract

The Automatic Water Level Control is a prototype circuit that controls the availability of water in a tank. The water tank has five water levels to control the pump work. The water level control system consists of two water containers, one for the water source container and the other for the water reservoir and two water pumps. The circuit consists of an infrared system, two relays to activate the water pumps and a 2x16 Liquid sensor to detect the water level, a microcontroller Atmega 8535(L) to control all the circuit Crystal Display (LCD) to display the water level in the tank reservoir and the pump condition. After the water level control circuit has been built and tested, it is known that at the minimum level position that is 30 cm between sensor and the float, the output voltage of the infrared sensor is 0,85 volt and the microcontroller will turn on both the water pumps. At the maximum level position that is 11.5 cm between sensor and the float, the output voltage of the infrared sensor is 2,17 volt and the microcontroller will turn off both of the water pumps. Keywords: Water level control, infrared sensor, Microcontroller, LCD

Abstract

Operating temperature of potential transformer design is 20 oC. However it is not applicable in Indonesia with temperature 30 oC. Because of that, the load of the transformer need to be adjusted. Operating lifetime will become shorter and loss of life will become greater at higher temperature. Loss of life of the transformer depends on winding isolation and transformer oil. Overheating in transformer winding can damage the isolation and increase oil temperature resulting in degradation of the oil. If the changes occur in a long period, it can decrease the isolation value of the oil. The final research observes the correlation between load of transformer and ambient temperature to the loss of life viewed from deterioration transformer winding insulation and analyze GTG 1.3 PLTGU Tambak Lorok Semarang Transformer loss of life refer to1972 IEC 354 standard. According the result, 80% of transformer load is caused minimum 24% loss of life. With IEC 354 standard’s transformer and 20 oC ambient temperature resulting in minimum 100% loss of life on 100% load. According to 20 load data, with maximum load of GTG 1.3 PLTGU Tambak Lorok Semarang Transformer loss of life is 15.69% Keywords: transformer, ambient temperature, loss of life
