Analisis Pengaruh Variasi Pembebanan Terhadap Kinerja Motor Primary Air Fan 3 Fasa, 6 Kv Unit 2 Di PLTU Teluk Sirih

2024-06-12T15:03:29+00:00

The 3 phase, 6 kV PAF motor is one of the induction motors used at the Teluk Sirih PLTU to produce air pressure that enters the combustion chamber (boiler). In Unit 2 of the Teluk Sirih PLTU there are 2 PAF motors. PAF motors experience changes in daily load in motor performance such as: input power, reactive power, output power and motor torque. The aim of this research is to study and see the performance of a 3-phase, 6 kV PAF motor regarding daily load changes during the generator performance test. From the analysis results it was found that as the generator load increases, the input power, output power and motor torque also increase, where at 16.00 the generator load is 100 MW for PAF A, the highest input power is 961.2918 kW, output power is 915.1498 kW, reactive power is 459 .2839 KVAR and motor torque of 5864.165 Nm.

2024-06-12T15:08:54+00:00

Alumni have an important role for an educational institution. Alumni involvement with an institution after graduation is an important factor affecting alumni support of their almamater. But these day there is no place that can facilitate the alumni effectively. Based on that case, there is a need to develop a system that can handle it. This system can display alumnis data and job, make a topic and leave a comment on forum discussion. This system is expected to facilitate the alumnis data management process and the final project in Computer and Information System of Universitas Ekasakti. Information system of alumnis portal for Computer and Information System of Universitas Universitas Ekasakti is web based and was developed using PHP, framework CodeIgniter and MySQL database. Information system design refers to the needs of the information required by the user, and modeled into diagrams contained in the method of UML (Unified Modeling Language). With this system, we can make a website that can accommodate all the information about alumni and jobs centrally with fast, precise, and accurate.The purpose of this research is to improve alumniss data management process and the final project more effective and efficient.

Analisa Pengelasan Baja St 37 Dengan Memvariasikan Kuat Arus dan Pendinginan Terhadap Sifat Mekanik

The aim of this study to determine the effect of electric arc welding results by varying the electric current and the cooling of the tensile strength and hardness on steel plates ST 37 with ASTM E 8. From the test results obtained the highest tensile strength of 52.21 kg / mm2 in strong currents 120 A with cooling water and the lowest tensile strength of 33.96 kg / mm2 in the strong currents of 120 A with oil cooling. As for testing the hardness HRB high of 107.33 on strong currents of 90 A with cooling water and low hardness of HRB 81 on the test material without getting treatment. ST 37 steel welded and cooling is done to change the tensile strength and hardness.

Along with the increase in the number of visitors from year to year, of course this has an impact on the increase in the volume of vehicles in the parking area of the Grand Mosque of West Sumatra. The size of the parking area which is not commensurate with the volume of existing vehicles will certainly disturb the order and comfort of parking users at the Grand Mosque of West Sumatra. The research method used in this performance analysis is a field survey of parked vehicle data and analysis. In carrying out this parking performance analysis, the results obtained were the highest volume of 276 vehicle units, the highest accumulation of 273 vehicle units, the highest average duration of 139,369 minutes/vehicle, the highest turnover (turn over) of 2,126829 units/SPR, the highest parking index of 133,170% and the number The highest shortage of parking lots is 84 units. So the existing parking capacity is currently not enough to accommodate the number of vehicles currently parked.

Evaluasi Daya Tampung Saluran Drainase Jalan Padang Pauh- Kampung Galapung Nagari Ulakan Tapakis Kabupaten Padang Pariaman

Water resources that can be obtained in this area include rivers, rain and springs. Padang Pariaman Regency is located in an area with lots of hills, making this area have many springs. So that this spring can be used for the survival of the population in the area. One of the uses of this spring can be done by planning and building a reservoir, where later the construction of this reservoir will be used for irrigation activities and clean water needs for the local population and also used to accommodate shortages and excess water. Padang Pauh area - Galapung Ulakan Tapakis Village, is a location with a fairly high degree of rainfall, namely with a rainfall intensity (I) of 126.432 mm/hour and the planned flood discharge for the 5 year return period is 0.832 m3/second. From the results of the above calculations, it is found that the capacity value of the existing drainage channel on Jalan Padang Pauh- Kampung Galapung Ulakan Tapakis is (Qs) 0.44224 m3/second, which is less than the planned flood discharge (Qr) of 0.832 m3/second so that the existing drainage is not capable. accommodate rainfall in the Jalan Padang Pauh-Kampung Galapung Ulakan Tapakis area.
