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.

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.

Public Street Lighting is a facility needed as a navigation aid for road users, increasingthe safety and comfort of road users, and supporting environmental security. The lack of lightingon the Ngurah Rai Bypass road is then performed a recalculation analysis and replacing theexisting lamps with LED types in order to maximize the lighting contained in the Ngurah RaiBypass. Measurements are made starting from the intersection of the Bali Mandara Toll roadtraffic lights towards (East) Sanur which ends at the first traffic light after the Bali Mandara Tolltraffic light, this road is an Arterial type road with a road width of 8 meters with a road length of1270m. The method used in this research is descriptive quantitative, that is, data collection isdone through measurement using objective and standard tools. The calculation results are thencompared with the conditions that occur in the field using IBM SPSS Statistics. Based on theresults of the research, it shows that the lamps installed with 10.21 lux still do not meet SNI 11-20 lux. Changing the type of mercury lamp to a 120 Watt LED lamp produces 13.21 lux, whichmeets SNI for PJU lighting.

Turbine is a component that plays an important role as an energy converter to be ableto generate electricity in the Micro Hydro Power Plant (MHP). The turbine used in this prototypeis a Pelton tubine. The Pelton turbine is a type of impulse turbine consisting of two blades as aprelude receiver for water jets from the nozzles by utilizing high water heads even though thewater discharge is small. This research will discuss the effect of the number of blades on therotation produced by the Pelton turbine and generator so that it can be seen the voltage,current, power produced that affects the torque value and efficiency obtained on the prototypeMHP. This study aims to obtain a turbine runner with the number of blades that can produce thehighest efficiency, then a variation of the pelton turbine runner is made with different number ofblade parameters from the runner with the number of blades according to the calculationobtained from the reference. Variations in the number of blades used are 14 blades, 16 blades,18 blades, 20 blades, and 22 blades. The results showed that the addition of the number ofblades starting from the smallest caused the performance of MHP to increase, the highestoutput obtained was using a turbine runner with a number of 22 blades which resulted in aturbine rotation of 852.2 rpm before the generator coupled and 497.2 rpm after coupling thegenerator. Generator rotation is 2133.8 rpm, Generator Voltage is 15.72 volts, Generator poweris 33.7 Watts and Torque is 0.6 Nm. The efficiency value using a runner with a number ofblades 22 is 4.54%. The resulting efficiency value is very low because the MHP prototype in generation is less effective and uses a small generation capacity DC generator, so it cannotgenerate power as much as hydraulic power.

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.

Gangguan hubungasingkat tenaga listrik ditimbulkan oleh hubung singkat tigaafaseasimetris, gangguan hubung singkat tidak simetris satu fase ke tanah dan gangguan hubung singkat tidak simetris antar fasa dan dua fasa ke tanah. Gangguan tersebut telah menyebabkan beberapa trip, kegagalan kerja relay dan recloser. untuk menentukan setting waktu kerja relay arus lebih dan recloser agar peralatan proteksi dapat bekerja dengan baik dilakukan simulasi gangguan hubung singkat pada beberapa titik lokasi gangguan yang dipilih berdasarkan kondisi di jaringan penyulang Mambal. Berdasarkan analisis, arus gangguan hubung singkat dipengaruhi oleh jarak tittik gangguan, semakin dekat titik gangguan dengan sumber maka semakin besar arus gangguan hubung singkat pada titik tersebut. Arus gangguan maksimum dan minimum hubung singkat mengakibatkan selisih waktu kerja relay di tiap lokasi dengan selisih waktu TMS selama 0,4 detik. Dilakukannya setting sistem proteksi pada penyulang Mambal sesuai dengan hasil analisis dapat memperbaiki selektifitas sistem proteksi pada Penyulang Mambal.
