The most widespread use of AC electric motors is three-phase induction motors, almost90% of motor applications in the industry use three-phase induction motors. The operation of 3phase induction motors generally has voltage imbalance disorders. Voltage imbalance affectsseveral things, including losses and efficiency. This study uses simulation method with the aimto determine the influence of unbalanced voltage on the characteristics of 3 phase inductionmotor and how to secure a 3-phase induction motor when it gets an unbalanced voltage supply.The result of this simulation obtained the smallest efficiency is 56.8% in the voltage dropcondition in one phase and 78.4 in the voltage drop condition in all three phases (R, S and T)with voltage asymmetry of 20% and the biggest loss is 11 406 Watts in the voltage dropcondition on one phase with voltage asymmetry of 20%. In the simulation of 3 phase inductionmotor protection system of unbalanced voltage supply obtained by tripping breaker fastest thatis at 0.201 s seconds with drop voltage condition 15% in phase S. 3 phase induction motorsafety pattern when getting unbalanced voltage supply is to use an unbalanced voltage safetysystem that has faster tripping delay time.

A disturbance in the groundhing system is caused by a disturbance current which isflowed to the ground which will cause a difference in tension on the ground surface dueto high ground resistance. On rocky soils with ground resistance in excess of 200 ?-meters it is very difficult to determine a suitable grounding system. The purpose of thisresearch is to analyze the design of an appropriate earthing system on narrow land onrocky ground which will be used as a reference for selecting the grounding system at atKampus Unud Jimbaran feeders. The method used is to take measurements on rockysoil then measure and determine the proper earthing design to use. The optimal resultsobtained for the grounding system on narrow land on rocky soil is a grid groundingsystem because it produces the lowest earthing resistance value in dry soil conditionsand wet soil conditions, namely 0.6269 ohms on dry soil and 0.4314 ohms on wet soil. has met the standard according to IEEE std 80-2013, which is <1 ohm with 16x16 rodsin an area of 4 m2.

Liquefied Petroleum Gas (LPG) leak detection and monitoring system is a step to anticipatethe danger of gas leaks. BPBD data for 2016 - 2020 fires due to LPG gas leakage are 50 cases,handling is still manual. The design of this prototype uses the Arduino NodeMCU 8266 module as themain controller. The sensor used by the MQ-6 sensor is suitable for detecting propane and butanegas in LPG. In order for the sensor to work optimally the sensor is set at a distance of 10 cm from thegas source. The prototype uses a solenoid valve which is a valve controlled with AC or DC electriccurrents through the selenoids. Buzzers and notifications via the telegram application complement theoutput of the prototype if a gas leak is indicated. The duration of the notification is sent depending onthe signal strength of the WiFi / provider used, while the duration of the buzzer sounds as long as thedetected gas level exceeds the value of the sensor set. The results achieved in the study, namely thegas leak monitoring prototype using the MQ-6 sensor based on NodeMCU 8266 was very effective.MCU node 8266 can be used to open / close valve electronics automatically. The ideal distance toread the gas leak smoke is 10 cm. The time the notification is sent depends on the signal strength ofthe WiFi / provider used, in this study it was found 80-92 dbm, the duration of the buzzer sounded aslong as the gas level was detected more than 200 ppm.

Frog thigh meat is one of the potential non-oil and gas export commodities. In 2011-2012 thevalue of frog thigh meat exports decreased from 4.152 tons to 2.694 tons. The scarcity of toadsavailable is due to massive hunting and the spread of red leg syndrome. Red leg syndrome is causeddue to lack of monitoring of the condition of the bull frog pond. A harassment solution is needed byutilizing the Internet-based technology of Things as an effort to create an environment, especially theright water content of the bull frog, so as to reduce the number of bull frogs affected by the disease.This tool is able to monitor pH values and water turbidity levels in aquaculture ponds through theThingspeaks platform. The test was carried out in one of the Beetle Fodder Animal HusbandryGroups located in Buduk Village, Mengwi District, Badung Regency. It was found that the pH value inthe pond was 6.5-8 and the turbidity level was 3,8-9 NTU. Based on these results, aquaculture pondsare in accordance with water standards for the life of a bull toad with a pH value of 6.5-8.5 andturbidity levels of 1.2-11.6 NTU

The Feeder of Sulahan Bangli is located in the highlands which are often exposed to natural phenomena in the form of lightning, so the Feeder of Sulahan Bangli often experience interference with over voltage. Lightning Arrester in The Feeder of Sulahan Bangli often experience failure due to overvoltages during lightning surges. In 2016 there were 4 times the overvoltage failure in conventional Lightning Arrester in The Feeder of Sulahan (PT. PLN (Pesero) UP3 East Bali, 2016). The failure of Lightning Arrester in The Feeder of Sulahan Bangli is caused by the interference of backback-flashover, this is caused by the earth resistance value in Lightning Arrester exceeds the standard value <1 ? which is an average of 8 ? so that it needs to be repaired grounding system. In this study an analysis of the area of the grounding system is installed, analyzing the various grounding systems that are suitable in the Feeder of Sulahan, and calculating the cost of each grounding system. The results of calculations and analysis of several grounding systems used by the Grid-Rod grounding system in wet and clay soils are the most optimal type of groundinging system that can be used as a reference for improving the grounding system in The Feeder of Sulahan Bangli with an earth resistance value of 0, 4543 Ohms at a cost of Rp. 5,416,625, - per unit and on a 0.4461 Ohm thick clay soil at a cost of Rp. 8,728,125, - per unit.

Kaplan turbine is suitable turbine to use in the place that have small water fall (head)but need big water discharge. The problem from this turbine is the turbine need high waterdischarge to test the related parameters but it is too difficult to do because the water dischargeis not constant in the river. Based on the problems described, it is necessary to make a hydropower plant prototype using a Kaplan turbine with a laboratory scale so that it can obtainmaximum output result on a micro hydro power plant. The Method of analysis used is bycalculating the rimary data obtained. Prototype testing in this study uses water discharge thatvaries including 9 liter/s, 10 liter/s, 12 liter/s, 14 liter/s and 16 liter/s. The maximum outputobtained is when the water discharge is 16 liter/s which produces a turbine rotation of 228,3 rpmbefore the generator is coupled and 172,5 rpm after the generator is coupled, the generatorrotation is 902,5 rom, the generator voltage is 9,07 Volts, the generator current is 0,56Amperes, generator power is 5,09 Watt, torque is 0,28 Nm, and the efficiency occurs 1,62%.Based on the result of the study, the maximum output obtained is from the water discharge 16liter/s which is the biggest water discharge because an increase in the value of water dischargewill cause the micro hydro power plant performance to increase.
