Analisis penggunaan power system stabilizer (PSS) pada sistem single machine infinite bus (SMIB) telah dilakukan dalam kondisi sistem mengalami gangguan pada input step mekanik sebesar 0,05 p.u. Penelitian dilakukan dengan mensimulasikan PSS pada dua pemodelan yang berbeda berdasarkan sistem kontrol lead-lag dan kontrol PID. Kemudian dibandingkan pemodelan sistem yang menggunakan PSS dengan yang tidak menggunakan PSS dari performa sudut rotor dan frekuensinya. Hasil yang didapat setelah menjalankan simulasi menunjukkan bahwa perbaikan yang dilakukan oleh lead-lag PSS dalam meredam overshoot dan settling time pada respon sudut rotor dari nilai 0,18 p.u menjadi 0,125 p.u dan mencapai kondisi stabil pada waktu 5,1 detik. Pada respon frekuensi dari nilai 0,0014 p.u menjadi 0,00082 p.u dan mencapai kondisi stabil pada waktu 2,2 detik. Perbaikan yang dilakukan oleh PID power system stabilizer (PIDPSS) dalam meredam overshoot dan settling time pada respon sudut rotor dari nilai 0,18 p.u menjadi 0,105 p.u dan mencapai kondisi stabil pada waktu 4,6 detik. Sedangkan pada respon frekuensi dari nilai 0,0014 p.u menjadi 0,00079 p.u dan mencapai kondisi stabil pada waktu 1,6 detik.

Pelton turbine is an impulse turbine that is different from other turbines where the peltonturbine utilizes a large high water fall (head), even with a small water discharge. The problemwith Pelton turbine is that the head is still difficult to control because this type of turbine uses ahigh head to rotate the turbine runner and there is no formula / equation to determine the angleof the nozzle which produces maximum output. Based on the problems described, it isnecessary to make a micro hidro power plant prototype using a pelton turbine with a laboratoryscale so that it can do the testing of the influence of water and the nozzle angle to obtainmaximum output results on a micro hidro power plant using a pelton turbine. The prototypetesting in this study used various water pressures, namely 5 psi, 9 psi, 13 psi, 17 psi, 21 psi,and 25 psi with nozzle angles, namely 60º, 75º, and 90º. Based on the results of the study, anincrease in the value of water pressure provided with an optimal nozzle angle will cause themicro hidro power plant performance to increase. The maximum output obtained is when thewater pressure is 25 psi with a nozzle angle of 90º which produces a turbine rotation of 917 rpmbefore the generator is coupled and 326 rpm after the generator is coupled, the generatorrotation is 1321 rpm, the generator voltage is 12.9 Volts, generator power is 30.96 Watt, torque is 0.98 Nm, and the highest efficiency occurs when the water pressure is 21 psi with a nozzleangle of 90º which is 3.91%.

Analysis of the EDF (Electric Ducted Fan) thrust motor test and the determination of the takeoff system on the ATmega 328-based rocket vehicle is a prototype design of a thrust test tool that is used to measure the thrust output of a 70 mm EDF motor used as a vehicle propulsion engine. EDF rockets as well as a prototype rocket takeoff system that serves as a takeoff indicator using the data from the EDF thrust motor test as a reference for rocket liftoff. The data measured in the EDF motor thrust test are, among others, thrust data detected using a load cell sensor, RPM data (EDF motor rotation) detected using an infrared proximity sensor, PWM (Pulse Wide Modulation) output data from the mapping input potentiometer. and a 16x2 LCD module with I2C used to display test data. The thrust test data used on the prototype of the rocket takeoff system are RPM and PWM data with indicators ready to take off using green LEDs. The prototype of the take-off system of the rocket vehicle is based on the ratio between the thrust of the EDF motor and the rocket's weight (thrust to weight ratio) of ?1. The results of the research when testing the thrust on the EDF motor with a 6 blades propeller obtained maximum RPM and thrust data of 73619 RPM and 695.3 g, for testing on the EDF motor with a 12 blades propeller obtained the maximum RPM and thrust data of 65861 RPM and 696.2 g RPM, where all these data is obtained when 100% PWM output from Arduino to ESC (Electric Speed Controller). Thrust to weight ratio produced on each EDF motor with 6 blades and 12 blades propellers is 1,202 and 1,189. Takeoff system uses PWM input reference to brushless motor ESC at 100% ratio

PT. PLN (Persero) South Bali Area built the Pecatu GIS to level the load, improve serviceand reliability of the electricity distribution system. The transfer of electrical loads to the PecatuGIS changes the configuration of the Pecatu feeder to the Uluwatu feeder and the Labuan Saitfeeder. Changes in load current and network impedance have an impact on short-circuit faultcurrents. The calculation of short-circuit fault current becomes the basis for determining theworking time of the OCR and GFR relays between the recloser and the feeder base PMT. Therelay working time based of the PLN regulation setting protection at 0,1 seconds to eliminatefault currents and IEC 60255 standard take 0,3 seconds to eliminate fault currents. The resultsof the study showed that the time value of PLN's regulation Tms was 0,076 SI and 0,033 SI.The results of the calculation of (Tms) standard IEC 60255 obtained time (Tms) 0,23 SI and0,09 SI. The simulation results of the PLN regulation relay settings and IEC 60255 work wellwith a grading time value of 0,2 – 0,4 seconds.

One of the most influential factors on the grounding system is the type of soil. Each soilhas a different resistivity. So, it is necessary to add media in the form of additives, one of whichis a mixture of gypsum (CaSO4`.2H2O) and Calcium Oxide (CaO). The purpose of this researchwas to obtain the percentage of the mixture and the effectiveness between gypsum(CaSO4.2H2O) and calcium oxide (CaO) to obtain the maximum quantity of water and to decidethe impact of a mixture of gypsum (CaSO4.2H2O) with calcium oxide (CaO) as a medium foradditives. to reduce the resistivity of the soil. The method used in this study is an experimentalresearch method. The results of this study showed that the mixture of gypsum and calciumoxide that was effectively used was a mixture with a ratio of 3 kg of gypsum and 1 kg of calciumoxide and the percentage decreased resistance value was 37.93%

Sistem monitoring output dan pencatatan data pada panel surya adalah suatu alat yang digunakan untuk memonitoring dan mencatat output dari panel surya. Biasanya dalam memonitoring panel surya dilakuakan dengan alat ukur manual dan mencatat hasil pengukuran secara manual yang tentunya memerlukan tenaga manusia yang lebih banyak. Maka alat ini dibuat untuk dapat memonitoring dan mencatat output dari panel surya secara otomatis. Metode dalam perancangan ini dibagi menjadi dua yaitu perancangan perangkat keras (hardware) dan perancangan perangkat lunak (software). Alat ini menggunakan mikrokontroler Arduino Uno sebagai pengontrol utama dan SD Card berkapasitas 8 GB sebagai media penyimpanan nilai arus, tegangan dan daya Output dari panel surya. Dimana dengan SD Card tersebut dapat menyimpan data output panel surya kurang lebih hingga 3860 Tahun.
