Abstract

The estimation of power consumption within Pekanbaru area in the coming decades is being analyze using of the software Long-range Energy Alternative Plan Systems (LEAP). The calculation is done by putting some variables of electrical energy consumption and the grow of electric consumption. The result of LEAP analysis is showing the grow of power consumption during period of 2015-2024 by 9,63% per year or in the other word increasement from 1667,43% GWh into 3943,04% GWh. The government and electric company (PLN) need to put attention and effort to make sure the figure of grow are able to realize. The effort is indicated by localizing the potential of power generation to be build within the area of Riau Province. Those potential of power generator includes some renewable energy i.e Microhydro Power Plant, Solar Power Plant Centralized, Solar Street Lighting, and biomass/biogass plant. Some of typical resources can be considered such as water potential, coal potential, and peat potential.Keywords: Electricity, Intensity energy, LEAP, Renewable energy

Abstract

This study describes analysis of tower footing resistance effected backflash voltage across a transmission line 115 kV insulator at PT. Chevron Pacific Indonesia. Back flashover analysis on insulator string provides ATP software for simulation. Analysis process is done by the entire transmission line parameter model such as a tower, lightning impulse, power line conductor and tower footing resistance. The factor of this study includes,front time of lightning stroke, and tower resistance. Simulations is done with lighting strike on the tower and mid-span with four types of impulse. To analysis of tower footing resistance effected back flashover across a transmission system insulator, Simulations are done by varying the tower footing resistance from 1Ω - 30Ω. Over Voltage on insulator for every tower footing resistance will be compare to critical flashover insulator (CFO) in order to obtain the maximum resistance is allowed to avoid the back flashover on insulator.Keyword: Tower fotting resistance, Back flashover, ATP, Insulator

Abstract

Solar thermal energy is a renewable energy which is very large in the universe. Indonesia as a tropical country has a huge potential where almost all the islands in Indonesia has solar thermal radiation every year. One of utilization of solar heat is to use solar heat as a source of electrical energy. solar thermal power generation technology, one of which is use a stirling engine as a converter of solar thermal energy into kinetic energy. Then the kinetic energy is connected to a generator that can produce electrical energy. One important part in the generation of solar thermal energy with the stirling engine method is the solar thermal collector which is generally a parabolic shape. In this study, a parabolic collector was designed using TracePro simulation software. TracePro Software is able to simulate solar thermal energy by providing several parameters, then it will display the performance of a paraboilic dish collector against sunlight as well as the parameters needed in research. From the results of the simulation, it was found that the ability of the maximum parabolic collector with 40 Watt/m2 solar radiation input was able to focus solar radiation to 500 W. From the results of the manual calculation there was an error between the simulation and the manual calculation is 16,6 %. Thus the performance of the parabolic dish collector by 83,4 % (efficiency).

Abstract

Utilization of renewable energy sources and conversion devices increasingly varied. Sago waste as a source of cleanliness issues, can be viewed as a source of alternative energy with green technologies both of process and product. Construction of biogas power plant (PLTBiogas) is a solution of renewable energy (EBT) to increase energy needs and help to reduce dependence on fuels (fossil energy). To reduce the cost of fuel, optimalize schedule of thermal generating units in the system need to be done . Problem related to the schedule is the Economic Dispatch consists of dividing the load at each generating unit in order to obtain a combination of generating units to meet the load demand with optimum. Dividing of cost of load for each thermal generating unit can be obtained by using the lambda iteration method. This methode can achieve more optimal results .Keywords: Construction of biogas power plant (PLTBiogas), Economic Dispatch, Lamda iteration

Abstract

Chicken eggs can be hatched in two ways namely, incubated by a hen directly and by using a created egg hatching machine. The egg hatching machine replaces role of the hen in egg incubation process. Checking hatching machines manually by checking the stabilities of temperature and humidity in the hatching room one by one, cause temperature and humidity instabilities to be a problem, so eggs are failed to hatch. This problem can be solved by using monitoring and pengendalian system of a hatching machine uses XBee Tansmitter and XBee Receiver in 5meters,10meters,20meters indoor. XBee Tansmitter is on incubation machine connected to Arduino-Uno-ATMega328. DHT22-Sensor detects temperature and humidity readings. XBee Receiver is on user’s space connected to Arduino-Uno-ATMega328. SD Card saves temperature and humidity data. Temperature and humidity monitoring in 24 days since eggs were put into hatching machine in 37.80C–38.70C temperature and humidity of 50%-60%. After 3 days eggs put into machine, Servo Motor turns back 1800 Egg’s rack within eggs every 3 hours, until eggs hatch. Eggs hatched since 19th day. Total of hatching eggs are 19 from 23. Can be concluded that the research work well because hatching eggs well reached 82.61%.

Abstract

The New Garuda Sakti substation (GI NGS) is a substation that function to reduce electrical power losses at Pekanbaru region. This substation has five feeders of 20 KV which are distribution the load from the previous feeders supplied from three substations. By calculating the amount of power losses, electricity costs, comparison of power losses before and after in the New Garuda Sakti Substation, it can be seen the effectiveness of the substation construction. The total power losses before being supplied from the GI NGS is 201,801.77 W and after being supplied from the GI NGS is 34,251.94 W. Then, the average power losses per month can be reduced by 43,600.05 W and the average savings cost per month is Rp. 26,468,513.33. Thus, the presence of GI NGS is very effective in reducing electricity losses for the Pekanbaru region and saving operational cost for the company.Keywords : The effectiveness of GI NGS, distribution load, power losses, average power losses

Abstract

The manufacturing process of dies and punches requires high precision to produce components that are exactly in accordance with the given design specifications. Every step in the manufacture of dies and punches must be carried out carefully to ensure that the final result meets the quality and safety standards required in the industry. The manufacture of dies requires extra precision. These are not just molds, but tools that are capable of providing consistent shape and precision in every molding operation. Punches, an equally important counterpart, are designed to fit dies and provide clean and precise cuts on the processed material. This process not only produces tools but also demonstrates a dedication to technical excellence and precision. Every step is taken diligently, from initial conception to implementation on the production line. In the world of manufacturing, dies and punches are about transforming ideas into solid reality, playing a crucial role in supporting the advancement of modern industry.
