The implementation of science and communities service project is aimed to minimize destitution by implementing self feeding and energy generating village concept. The specific goal of this project is the utilization of cattle dung to produce a biogas. The method is being used for this project is by illuminating and educating the community to be able to build and operate the cattle dung biogas digester by their own. In addition, the community is completely involved to this project since the early state of this project. By implementing the plastic floating digester, it is hoped that the communities be able to utilize the biogas digester and make their own domestic energy. The result of this program is an unit biogas digester by using cow dung as a feed stock. The plastic floating digester can produce a continue biogas as a fuel for cooking. The enthusiasm of the community in term of using and implementing the digester is quite high. It is expected that the community can build and implement the cattle dung digester to produce biogas as a domestic energy.

The steep coastal topography makes the traditional fisherman facing a difficulty for moving boat from/to the sea towards the mainland. With the slope of 2 - 3 meters, it required at least 4 people do the job. This situation is very disturbing and reducing the productivity of the fishermen itself. Therefore, it needs a special equipment or appropriate technology to overcomes the drawback situation. So that, it will improve the efficiency and effectiveness of fishing operations. The method used in this study is an applied research method which the tool is designed based on real phenomena. Moreover, the outcome is the design of boat transfer device that will be used as an additional supplement to the teaching material of design and product development, industrial management, as well as a scientific publications. The design expected can improve the steep coastal fishermen productivity and welfare.

Melia Bali-Indonesia Hotel is the first hotel of Sol Melia's management, which subsequently becomes the Bali Sol Hotel. This hotel was supplied from transformer 1 of the Melia Bali Hotel via MDP1 with 9 SDPs, with priority to supply electricity to rooms and villas. Based on the measurement results obtained currents: at each phase namely: phase R = 456 A, phase S = 445 A, phase T = 412 A and power factor of 0,84. A power factor of less than 0,85, based on the determination of an electric power tariff adjustment from PT PLN, may be subject to excess reactive power usage fees (Regulation of the Minister of Energy and Mineral Resources of the Republic of Indonesia Number 28 of 2016). Based on these data, an analysis of the installation of capacitors was carried out to increase the power factor in transformer 1 of Melia Bali Sol. The method used is to use simulation modeling with ETAP. Based on the results of the analysis of the installation of capacitors can increase the power factor by 11% to 0,95, already exceeding the minimum average power factor determined by the PLN electricity tariff adjustment. In addition, the load current decreased 12% from 442.3 A to 389.5 A.

Protected forest areas have the main function of protecting life support systems. The protected forest area of ??Ekasari Jembrana Bali has an area of ??1.603 hectares. In the Ekasari protected forest there are many illegal logging actions. In 2020 there were two cases of wood theft. The types of wood stolen were reed and rosewood. In addition to these two cases, in 2018 to 2019 there were more than 10 cases of illegal logging that occurred, it is necessary to have a tool that is able to detect the occurrence of illegal logging in protected forests. The working system of this tool uses a Pi NoIR camera module to take pictures and a sound sensor FC-04 to detect the sound of a chainsaw with a value of 55 dB. This tool uses a Raspberry Pi microcontroller which functions to receive and process data, so that it is able to display warnings on websites and telegram applications. This tool has a detection range of 1,1304 hectares, so 1.418 tools are needed in the entire protected forest area of ??Ekasari Jembrana Bali.

In the process of electrical power distribution, various types of interference can occur so that a protection system is needed to maintain the continuity and stability of electrical power distribution. Arrester is one of the main protection systems used to protect electrical equipment against overvoltages caused by lightning strikes. Penyulang Sulahan is a 20kV medium voltage distribution system that gets power supplies from Gianyar Substation 1/60 MVA and is located on a plateau that is prone to natural phenomena such as lightning. During 2016 there were three times the failure of conventional arresters. Based on these data, it is necessary to analyze the failure of arresters at Penyulang Sulahan so that the continuity of electricity can be better. The method used in this study is to collect data in the form of single line diagrams, disturbance data, and large grounding resistance on Sulahan Feeders. Next, compare Metal Oxide Arrester with Multi Chamber Arrester. The results obtained were grounding in the Feeder over 5 ohms which caused conventional arrester to not work properly. Multi Chamber Arrester is an arrester that has no effect on the value of grounding resistance. After installing the Multi Chamber Arrester, failure of arresters has decreased to one failure during 2017

Utilization of sunlight as a source of renewable electrical energy by using photovoltaic (PV) has been done by many public and private agencies. One of them is Badung Regency Government. Power source for Main Street Lighting (LPJU) with the number of lamp posts 305 installed along the road By Pass I Gusti Ngurah Rai. This study analyzed the effect of position change on the efficiency of LPJU solar panel. The simulation of this research using PVSyst software and compared with real measurement result to get the position of solar cell that can produce optimal output power and better efficiency value. The result of comparison of rill measurement with PVSyst simulation, in zone 1 obtained maximum energy generation of 60,42 kWh, 186,40 kWh, at zone 2 equal to 72,54 kWh, 186,40 kWh, at zone 3 equal to 33,97 kWh, 186.40 kWh, in zone 4 of 61.52 kWh, 186.40 kWh. The PVSyst simulation results show that the solar cell output power is higher than the rear measurement in different directions and the efisiesin value obtained is better than the previous rill measurement.

The increasing. use of non-linear loads can make. harmonic distortion in the current andvoltage waves so that it can reduce the. reliability and quality of the. power system. Non-linearloads that are often used are induction motors, consequently the use of induction. motors willhave an impact on the high harmonics. of the system. The impact. of these harmonics can bereduced by using a. hybrid filter. The method used is. direct measurement of the object understudy in the form. of current data, motor rotation and 3 induction motor THDi. This researchuses a Simulink-based simulation. which aims to reduce the. harmonic content in. the networkand to see the effect of harmonics. on the performance of the. 3-phase induction motor onrotation and torque. The. results of the. analysis show. that the hybrid filter. can. reduce theharmonic content in the network. The decrease that occurs in THDi is 11.96% in the R phase,11.95% in the S. phase and 11.96% in the T phase with a load of 3 motors. Using hybrid powerfilter is able to make the motor rotation stable at 0.17 s. However, the rotation. of the. inductionmotor remains at. 1498 rpm and a torque of 0.4682 Nm.
