Abstract

A Tsunami is a series of massive oceanic waves resulting from profound tectonic activities in the seabed. The disaster's devastating effect makes fast information delivery during a tsunami crucial in minimizing losses. For this reason, Tsunami warning systems need to be supported by a rapid detection technology. In recent years, radar has been implemented as a tsunami detector due to its sensitivity to oceanic waves. An array antenna using advanced microstrip technology, as the main component of a radar system, can fulfill the requirement for tsunami rapid detection. This paper presents the work that we conducted to develop a tsunami detection antenna using the array approach to improve gain and optimize radiation patterns. We designed a patch antenna with 12 mm in length and 21 mm in width and performed some simulations to obtain the antenna parameters such as gain, bandwidth, and optimal radiation patterns. As the results of our investigation, we determined the resonance frequency to be 5.4 GHz. The study produced a gain of 9.07 dB through simulations on an antenna that resonates at a frequency that meets the antenna work criteria, which include a loss of -26.69 dB, a VSWR of 1.09, and an HPBW (Half Power Beamwith) of 17.3°. Those values indicate that the antenna designed for tsunami detector applications functions correctly.

Abstract

AbstractDuring the distribution process there will be a loss of some of the energy that is channeled. This phenomenon is known as losses. This is caused by technical and non-technical factors. In the  State Electricity Service (PLN) system, distribution losses or energy losses is calculated by measuring the difference between kWh produced and kWh sell. This kWh difference is the electrical energy lost during the starting process from the generation or secondary side of the Substation to customers’ APP. Cumulatively, the amount of kWh at all base sources is 73,769.524 kWh while the distribution loss that occurs in JTM is 5,835.008 or 7.91%. One way to overcome and minimize distribution losses in the 20 kV Procurement Service Unit (ULP) of Lima Puluh distribution system is to analyze the distribution network system, add new feeders and break the load on the electrical system. The simple branch exchange method is used to separate the network load, which is done by adding a switch by turning the on or off channel and searching for the configuration that produces the smallest power loss and calculating the power loss based on the network load. Based on the simulation results using the ETAP 12.6 software, the results of the energy loss of Procurement Service Unit (ULP) of Lima Puluh is 5,864,112 kWh then decreased after load separation of 4,341,348 kWh. The value of power loss before load separation is 1,955 kW and a decrease in power loss after load separation is 1,484.5 kW. The investment cost incurred for the construction of a new feeder is RP. 22,000,000,000,- with a payback of 9.9 years.  Keywords: Feeder, Power Loss, Energy Loss, ETAP 12.6.

Abstract

The use of electricity has now become a primary need for people who are used for activities as an energy source such as: lights, air conditioners, water pumps, washing machines, TVs, etc. and the longer the need for electrical energy in Indonesia is increasing while power plants are constantly increasing, this forces the government to continue to build power plants to meet the needs of electrical energy in the community. Of course, the construction of this power plant uses very large costs and various obstacles, one of the obstacles is that fuel that used to be a power plant used a lot of oil, now switches to gas and coal to reduce high electricity production costs. The research method that will be carried out is by feeding the generator output back into a rotor drive energy source so that there is a continuous circulation of energy so that the generator output can be charged according to the remaining power capacity fed by the generator. Based on the test results, results were obtained using a 25 Watt DC motor when the input voltage was 12 Volts the power generated on the motor was 13.8 Watts with a motor speed of 768 rpm. Testing on an 800 Watt generator obtained a maximum rpm result of 764 and a vout of 13.8 volts. the highest input voltage (Vin) obtained was 10.06 volts, the output voltage (Vout) was 3.9 volts, and the power produced was 41.34 Watts. The prototype design that was tested produced energy even though the results were still not significant.
