Abstract

Along with the development in the field of lighting, LED, LHE and TL is now widely used as agood lighting for home lighting and street lighting. The lamp is also said to be capable of energysaving lamps produce light more efficiently than incandescent bulbs. Energy saving lamp is a nonlinearload that can cause disturbances in electrical power systems are referred to as harmonics. Asan energy-saving lamp has a non-linear load that produces both harmonic current harmonicdistortion and voltage harmonics. In this research, a combination of LED lights, LHE, and TL. Of thethree lights which have the greatest harmonics are LED lights. To suppress harmonics of LED lightscan be done with a combination of LED lights and lights LHE.

Abstract

Asbestos is a mineral that occurs in rock and soil, containing of magnecium-calcium-silikat fiber. Because of its fiber strength and heat resistance, asbestos has been used in a variety of building construction materials for insulation and as a fire retardant, such as heat-resistant fabrics, packaging, gaskets, and coatings, doe to its ablility whirstand in temperature up to 2.750 °C. Asbestos fibers may be released into the air by the disturbance of asbestos-containing material during product use. In general, exposure may occur only when the asbestos-containing material is disturbed or damaged in some way to release particles and fibers into the air. The severity of asbestos-related diseases, the material's extremely widespread use in many areas of life, its continuing long-term use after harmful health effects were known or suspected, and fact that asbestos-related diseases can emerge decades after exposure ceases. When materials that contain asbestos are disturbed or damaged, fibres are released into the air. When these fibres are inhaled they can cause serious diseases. This paper will describe the harmfull of asbestos emission to the environment. Mesothelioma is a cancer which affects the lining of the lungs (pleura) and the lining surrounding the lower digestive tract (peritoneum). It is almost exclusively related to asbestos exposure and by the time it is diagnosed, it is almost always fatal.

Abstract

Water is the main products and basic necessities in the process of generating electrical energy in a steam power plant. Several processes are needed to produce water with permitted conductivity and PH. Steam Power Plant Paiton 2 x 400 MW has two water treatment plant unit with demineraleralized water products flow 2 x 108 m³/ jam. Filling process of steam power plant is started by charging Hotwell condensor of Condensate Storage Tank (CST). By using condensate pump, water is pumped into the Deaerator, then fill the drum with pump Boiler Feed Pump (BFP). In the drum, separation of water and vapor phase will occur. Pressurized wet steam is heated using steam superheater to produce dry steam and supplied to the turbine by settings via Main Stop Valve. Because the generator and turbine are in the same axis, generator is now able to produce electricity. There will be excess water in the Condensate Storage Tank in charging state due. Manual operation which can waste demineraleralized water which furthermore can cause losses and decrease efficiency in the operation system. With the addition of the level sensor in the Condensate Storage Tank, overflowing water in demineraleralized water filling the tank can be avoided.

Abstract

Solar energy (solar) provides many benefits to human life. One of the utilization of solar energy that can be done is in the form of Solar Power Generation (PLTS). In this thesis will design of a solarcell power system with a capacity of 10 MW on-grid with location in Yogyakarta. Performance solar cell power system 10 MW on-grid simulated using software RETScreen Clean Energy ProjectAnalysis Software, which was designed by Natural Resources Canada. The project began with a prefeasibility study of the solar cell power system 10 MW on-grid using RETScreen software that hasan extensive database of meteorological data including daily global horizontal solar radiation and also databases of various components of renewable energy systems from different manufacturers.Technical and financial performance of the solar cell power system 10 MW on-grid simulated using RETScreen software. Preliminary analysis of the simulation results show that this project is sociallybeneficial to the community. The draft is expected to be used as a model to develop a network of Solar Power System (PLTS).

Abstract

PLN is the only company in Indonesia that serves and supplies electricity which is a necessity for many people. Various PLN’s customer needs electricity to do all of their activities. However ifthere is an interference in the electricity distribution, then all of the activities will stop. That results the decrease of PLN’s quality of service and must be increased by handling all of the interference as quickly as possible. One of the tools to solve electricity interference quickly and accurately is by developing an expert system. In this research, an expert system was developed to help identifyingelectricity interference quickly and accurately from customer’s reports. Case based reasoning is the method that is used in developing the expert system in this research and backward chaining is the inference machine. Based on the results of the verification and validation of PLN’s expert, interference unit operator, and field technician; showed that the system was able to identify theinterference that occurred and gave an accurate solution toward customer’s report.

Abstract

The analysis of autofrettage on fatigue-crack propagation of crack are well documented, that is experimental work shows the effects of positive stress ratio or tensile-minimum stress during thefatigue cycles on the fatigue-crack inition from holes. This simulates model the effect of the residual-tensile stresses at the outside surface of autofrettage cylinders. S-N curves and modifiedGoodman diagrams are shown for fatigue-crack inition. This allows a tremendous advantage in retarding crack initiation and propagation in the early stages of crack growth, wich accounts for thedramatic increases in useful service life for an autofrettage cylinder compared to a nonautofrettaged cylinder.

Abstract

KWH meter system of Automatic Meter Reading or hereafter will be referred to the kWH meter AMR is a recording system of electric energy meter is done automatically and remotely.Communication data sent by the kWH meter AMR of PT PLN (Persero) Jakarta and Tangerang Distribution using SMS modem which interfacing kWHmeterselectronic withwireless telecommunications networks. kWH meter AMR have features other than noting the energy used, also noting the voltage, electric current, power factor(cos ϕ), and as well as the use of electricity meters in record-keeping more quickly. Thus the PT PLN (Persero) Distribution can perform distribution network management (DNM) that makes it easier in terms of channeling energy into customers and monitoring the electric energy usage by customers. The results of the analysis of kWh meter AMR system can reduce losses caused by abnormalities in the distribution network system. SMS telemetry signal communication with the modem is unstable and often fail withdrawal data. To overcome the problem of the use of the old modem, the modem needs to be replaced with GPRS / LTE user ready. However, the use of power line communication (PLC) as a data transmission network to reduce reliance on mobile telecommunications networks.
