The fires of peatlands on oil palm plantations are very vulnerable to occur in the dry season. Fires will arise due to a decrease in the surface of the water resulting in the top layer of peatland becoming dry. Manually monitoring ground level is very difficult. The solution is to make a remote water level monitoring prototype in order to be able to regulate irrigation on peat land and make the system open and close the irrigation door during the dry season and when the rainy season arrives. The design of groundwater level monitoring uses a program installed on the Arduino Uno microcontroller.Water level data is sent by prototype via GSM SIM 800L network, 8 level conditions that have been determined from a depth of 15 cm multiples of five so on to 55 cm. HC-SR04 Ultrasonic Sensor is a detector for water level. Data can be accessed at any time via SMS by sending "Check" to the prototype. The results of the tests performed indicated that the tool can function in accordance with the design and send information as well as receive monitoring orders.

Rancang bangun sistem tracking panel surya berbasis mikrokontroler arduino merupakan sebuah alat yang digunakan untuk mengikuti arah pergerakkan matahari setiap jamnya, mulai dari terbit hingga terbenam. Sistem tracking panel surya ini akan mendeteksi setting waktu yang diinput oleh RTC (Real Time Clock). Pembuatan sistem ini dibagi menjadi dua bagian yaitu pertama adalah perancangan perangkat keras (hardware) yang terdiri dari perancangan perangkat elektronika dan perancangan perangkat mekanik. Kedua adalah perancangan perangkat lunak (software). Pemrograman sistem tracking menggunakan software arduino. Panel surya digerakkan dengan menggunakan motor servo yang bergerak sesuai input waktu yang diberikan oleh RTC. Pergerakkan panel surya diatur setiap jam dengan sudut yang telah diuji, sehingga posisi panel surya selalu tegak lurus dengan arah datangnya cahaya matahari. Hasil dari rancang bangun sistem tracking panel surya berbasis mikrokontroler arduino menunjukkan bahwa alat yang dirancang sudah dapat mengikuti pergerakkan matahari berdasarkan waktu.

Harmonics are disturbances in the electric power system in the form of distortions incurrent and voltage waves caused by the formation of waves with a interger multipliedfrequency of the fundamental frequency. Total Harmonic Distortion (THD) is the amount of theeffective value of waves affected by harmonics that affect the occurrence of electrical powerlosses. This study discusses the analysis of current THD in the lecture building at the Faculty ofEngineering, Udayana University, Jalan PB Sudirman. The simulation is carried out underexisting conditions and when operating an active filter will show the results of the THD currentthen adjusted to the IEEE 519-2014 standard. Then an analysis of power losses due toharmonics is performed. THDi in the existing conditions for phase R = 15.44%, S = 15.6%, andT = 11.42% while the active filter operation is at phase R = 2.41%, S = 2.69%, and T = 2.99%.Power losses due to haronisa interference under existing conditions were 12,6 % and on theactive filter operating conditions were 0,037 %.

RSUD Klungkung is supplied by a transformer with a capacity of 200 kVA. The use of non-linear loads in Klungkung Hospital can cause harmonic currents (ITHD). The greater the harmonic current produced, the quality of the electrical power will get worse, causing losses to the transformer. The installation of active shunt filters and the use of fuzzy logic controllers as controllers on filters can reduce the harmonics that occur in the electrical system. The results of ITHD measurements on existing conditions for R phase are 11.23%, S phase is 14.72%, and T phase is 11.20%. The ITHD value decreased when the system was paired with a shunt active filter for R phase of 5.24%, S phase was 7.18%, and T phase was 5.34%. The ITHD value has decreased again when the use of fuzzy logic controller for R phase is 0.15%, S phase is 0.17%, and T phase is 0.11%. Decreasing ITHD values affect the losses generated on the system. In the existing conditions losses are 10.525%, losses in the operation of the shunt active filter are 1.352%, and the use of fuzzy logic controller produces the smallest losses of 0.00035%.

The increase in the need for electrical energy in Indonesia is increasing along withpopulation growth. Followed by the depletion of fuels originating from fossil energy. Based ongeographic conditions, Indonesia has many rivers so that it has the potential to generateelectricity by utilizing the flow of water which is called PLTMH (Microhydro Power Plant). Inrealizing this PLTMH, one type of water turbine can be used, namely the Kaplan turbine, wherethis type of turbine works at low head conditions with large discharge. The purpose of thisresearch is to analyze the performance of the Kaplan type turbine guide vane prototype atangles of 15º, 30º, 45º, 60º, 75º, and 90º to meet the electricity demand in Indonesia. Afterbeing examined based on all the variations tested, the maximum value of the turbine rotationalspeed at an opening of 15º with the rotation values obtained before and after coupled with thegenerator were 249.5 rpm and 216.5 rpm. The value of the generator rotation before and afterthe 30 Watt load coupling is 1096.6 rpm and 999 rpm. Voltage, current, and power producedare 9,1 Volts, 0,68 Amperes, and 6,18 Watts. The resulting torque of 0,27 Nm. The greatestefficiency was obtained at a combination of the opening angle of the guide vane of 15º at2,62%.

The rapid development in the South Kuta region has resulted in an increase in the demand for electricityenergy that must be supplied by the 150 kV Nusa Dua substation. An increase in the amount of load results in anincrease in the load that must be borne by the transformer. To prevent losses due to overload, a load adjustmentsimulation is performed on the transformer at the Nusa Dua Substation. Load flow simulation is done using ETAPsoftware with the subject of the power transformer load along with the load-feeders. The purpose of the simulation isto know the loading conditions and power loss of the Nusa Dua substation system. Furthermore, the transformerload adjustment scenario is designed, then simulated again with ETAP software to determine changes in the loadingconditions and the power loss in the Nusa Dua substation system. Simulation results in existing condition withnormal operation, transformer 1 load is 69,8% and transformer 3 is 71,8% with a total power loss of 14,1%. After 3planning scenarios for transformer load adjustment, scenario 2 is the bestl scenario in short term with the loading ontransformer 1 is 50,4%, transformer 2 is 45,9%, and transformer 3 is 45,1% with total power loss of 9,16%. While forthe long term, scenario 3 is recommended by adding a new transformer unit. Transformer 1 loading is 50,9%,transformer 2 is 45,9%, and transformer 3 is 45,1% with a total power loss of 9,24%.
