GIS (Gas Insulated Switchgear) is a system of connecting and disconnecting the power grid which is packaged in a non-ferrous tube, using gaseous sulfur hexaflouride (SF6) as the insulation medium. The 150 kV of GIS Pecatu is located in Pecatu Village, South Kuta, Badung Regency, Bali Province. This GIS was built to help supply 120 MW of energy because of the load in Badung area, especially Pecatu and Nusa Dua, is increasing. So, it is necessary to know the differential relay current settings when there is a fault of short circuit in GIS Pecatu to produce an effective, selective and reliable safety system. When there is a fault of 11.58 kA the relay will work immediately within 0 SI, this proves that the differential relay with Instantaneous characteristics will immediately command a trip when the fault current has surpass the set value. From the calculation results, the setting of the main safety relay has worked in appropriate with the SPLN standard No. 52-1 1984 for the 150 kV system.

The wheelbarrow is a tool for transporting material in mining, plantation, and other areas that is pushed by one person with two rear handles and one wheel in the front. However, its use still requires and relies on a large amount of human power. The workers still have to expend energy to push the wheelbarrow which of course will be very heavy if the load is added in the wheelbarrow. Therefore, it is necessary to add an additional driving force to the wheelbarrow that can help the workers so that they can save their energy and also can make work more efficient. This wheelbarrow will use a DC motor as the driver and use Arduino uno with the PWM method as the control system. In addition, the tool will use a Lithium-ion battery so that it is more durable and can be easily recharged. The battery used has a voltage of 24V and a capacity of 9Ah. This semi-automatic wheelbarrow that uses a dc motor can help work faster up to about 32.5% more efficiently than without using a dc motor. In addition to being more efficient in use, wheelbarrows with dc motors also make it easier for users to use these tools compared to wheelbarrow without dc motors.

The increase in demand for electrical energy in Indonesia causes a reduction in conventional fuel reserves. This situation forces people to look for alternative energy sources or commonly callednew and renewable energy (RE). Seeing the geographical condition of the environment in Indonesiawhich has the potential for the development of electrical energy by utilizing the flow of water, it iscalled a Micro Hydro Power Plant (PLTMH). In implementing MHP, one type of impulse turbine canbe used, namely the Turgo turbine. This study focused on knowing the effect of variations in thenumber of blades on a turgo turbine on rotational speed, torque, voltage, current and power producedby PLTMH using a Turgo turbine, with variations in the number of blades used, namely 18,16,14,9,8,and 7 blades. The method used in this research is quantitative experimental, all combinations ofparameters tested get the result that the highest output characteristic value occurs using a runnerwith a number of 18 blades, where the voltage, current, and output power are 8.30 Volts, 0, 88Ampere, and 7.27 Watt. The fastest turbine rotation results are 782.8 rpm before being connected toa generator and 565.4 rpm after being connected to a generator, while the generator rotation resultsare 1062.4 rpm. The highest torque produced is 0.1Nm, the maximum efficiency obtained at therunner blade variation is 18 blades, which is 1.1%.

COVID-19 is a virus that attacks the respiratory system, has a negative impact on health. The impact of the pandemic is the reduced number of tourists visiting the island of Bali, making sources of income very limited. This directly has a detrimental impact on hotel managers in Bali. With the policy of reducing the number of employees, it is clearly detrimental to all parties and we can see that several hotel facilities have been damaged, one of which is in the garden. In this final project, a garden watering system based on the Internet of Things was designed using ESP8266. This system works according to a programmed watering schedule, rain sensor readings, and soil moisture sensors. The tool will water the garden when the time conditions are met, the rain sensor detects the absence of rain around the park and also when the relay is active, it flows voltage to the solenoid valve to open the water flow to the Sprinkler. Then the watering data will be sent to the Thingspeak cloud which will also be accessible by applications on smartphones. Monitoring information will be displayed on the LCD and also the application on the smartphone. An IoT-based automatic hotel garden watering system prototype using ESP8266 is able to run according to design.

Indonesia as a maritime country with 2.23 million people working in the marine sector, one of which is a fisherman. Fishermen are one part of the fishing unit that plays a very important role for the success of a fishing operation. This paper reviews the fleet of vessels used by fishermen in Indonesia. The research method is a literature study taken from books, papers, the internet, and other sources that can support. The results of the review show that in carrying out fishing activities, fishermen in Indonesia use traditional and modern boats or boats. Types of boats or ships are divided into several categories. Depending on the type of fishing gear such as purse seine, trawls, dredge net, lift net, gill net, pole and line, long line, tonda ship, jungkung, and based on the propulsion system and ship size divided into powered boat and non-powered boat. In the operation of the ship, electricity is supplied by generators or batteries or batteries. To drive the sailing ship, a motorized engine is used, which is divided into inboard and outboard engines based on the layout, and is categorized into marine diesel engines and marineized engines based on their design and designation. On the other hand, to optimize the production of potential fisheries resources owned by Indonesia, it is necessary to increase the number of ships. The fluctuating growth in the number of vessels from 2002 to 2016, with the largest number of vessels amounting to 815,544 units in 2014 has not been able to maximize production from this potential. The Indonesian shipbuilding industry has also not developed in line with the challenges it faces. Development is still lagging behind the capacity, potential, demands and demands of the market. As well as social organizations also have an important role to increase capture fisheries production by providing guidanceThe information presented is expected to help the interests of the community such as the central government, local governments, researchers, students, and anyone who is interested in supporting the field of fishing vessels in Indonesia, especially the application of solar power plants on fishing boats.

The increase in the consumption of fuel oil causes the depletion of fossil fuel reserves. One alternative energy solution that can be utilized is electrical energy. One of the efforts to overcome the energy crisis can be realized in a creativity in the energy efficient car contest (KMHE). The Weimana Team of Udayana University participated in the urban concept category of electric motor drive under the name Agnijaya Vehicle. One important aspect in order to be able to compete and win the competition is the Motor Controller. In this paper, the results of the research are presented on a design of a Brushless DC Motor Controller based on the STM32 Blue Pill microcontroller and used to rotate the BLDC motor on the Agnijaya Weimana Urban Electric Vehicle. The specifications of the BLDC controller design are made to have a power dissipation inverter with a power of 1980 Watt connected to an 800 Watt sensored BLDC motor. The STM32 Blue Pill microcontroller-based Brushless DC Motor Controller has been successfully designed and manufactured and produces a sinusoidal output waveform containing switching noise when connected to a no-load BLDC motor. The performance to drive Agnijaya Wimana's Urban Electric Vehicle is capable of implementing a PWM duty cycle of up to 100% with an average current achievement of 24,775 Ampere, an average voltage drop of up to 48,485 VDC, an average power rating of up to 1200,5 Watt and a BLDC motor speed up to 419,5 RPM.
