TOEFL (Test of English as a Foreign Language) is a test used to measure a person'sEnglish proficiency. Generally, the TOEFL test is used as one of the requirements to graduateat domestic universities, to enter universities abroad, or to work in a country. In this research,the LMS (Learning Management System) was used for implement the TOEFL. LMS is anapplication system that was developed specifically to manage online class (e-learning), andshare subject matter. Moodle (Modular Object-Oriented Dynamic Learning Environment) is anLMS that is usually used in online learning activities. The results of this research that theTOEFL was successfully created as a Moodle plugin and according to the SUS (SystemUsability Scale) test that has been calculated, it got a score of 89, indicating this application hasa high level of feasibility.

Technological developments in the field of electronics to date have made the humanmindset advanced in the application of electronic equipment. One example of its development isremote control of electrical equipment. Many people use these developments as a means offacilitating life activities in solving problems that occur. The use of the internet in life can beused as an example in the use of technological developments. The internet is one of thecommunication media that has many benefits in increasing effectiveness, work efficiency, andmonitoring. The internet can be used as a transmission medium for control and monitoringsystems. With the internet, one can control electrical equipment and monitor the condition of thehouse. The concept originated from the Internet of Things or IoT. IoT is a concept where alltools and services in the system are connected to each other using internet media. Based onthese problems, a smart home system was created that functions as control of electricalequipment, smoke detection, monitoring of temperature and humidity in the room. Themonitoring and control system is integrated with Android applications and based on the Internetof Things.

As a power plant industry, PLTU Jeranjang OMU (Operation and Maintenance Unit) owned oneof 6.3 kV nominal voltage induction motor that has critical characteristic that drives the waterpump into the boiler room which always has to operate. This motor has been equipped withtemperature sensor in real time that can monitor the temperature of bearing motor. However,manual control is still applied in vibration monitoring. It is done by taking the vibration data oncea week, and there is no deviation data found in real time. The result of this study shows that theprototype of IoT-based vibration monitoring data logger that is designed using the blynkapplication obtained the average of sensor deviation of 2%. Alarm notification of each sensorsdeliver "warning" if the vibration value indicates ? 4,5-70 mm/s and alarm notification delivers"emergency" if the vibration value indicates ? 7,1 mm/s in concordance with the ISO 10816-3vibration standard. Although, the performance of sensor data storage has successfully storingthe data with 8 GB microSD card, then will be fully charged in 4629 days or 154 months and 3days.

Four Season Jimbaran Hotel is one of the hotels in Bali using a cooling system which isusually called the water chiller. The electrical energy consumption in Four Season Hotel is oneof the factors that increase the use of electrical energy in which the star delta system is stillused to switch on the pump. Along with the electricity rate which keeps increasing every year,the electrical energy consumption in Four Season Hotel can increase the operational cost. It isconcluded that one of the largest electrical energy consumptions is water chiller pump. Chillerpump is a pump used for pushing water flow towards chiller condenser and Air Handling Unit(AHU) when the water chiller system is still active. Starters of the chiller pump used in FourSeason Jimbaran Hotel are inverter and star delta. The method used in conducting research was calculation of the electrical energy requirement and cost in two pumps set by star delta atan initial frequency of 50Hz in water chiller pump 160 TR, compared with inverter system withthe decrease of frequency by 5Hz (45Hz) in water chiller pump 230 TR. Monitoring wasperformed by analyzing the consumption of electrical energy (kWh), temperature (°C), andhumidity (%) in every pump set by every system. In these two pumps, energy consumption(kWh) and cost were compared in daily, weekly, and monthly needs. From the result ofresearch, in inverter system, the frequency reduction by 5Hz in water chiller pump 230 TR cansave electrical energy of 117,120 kWh and the cost of IDR 130,471,680 in the next five years.The comparison analysis of operation of the chiller pump supplied with star delta (fixed speeddrive) with an inverter (variable speed drive) has a difference energy consumption of 117,120kWh in both systems and the difference cost is Rp. 130,471,680.00 in next 5 years.

The single phase to ground fault on the 150 kV transmission line GIS Pesanggaran –Nusa Dua Substation has a high fault impedance so that the distance relay as anauxiliary safety device cannot detect the disturbance. Directional Ground Relay (DGR)was chosen as an auxiliary protection relay to secure the system from single phase toground faults. Installation of auxiliary protection relays requires planning and relaysetting steps to obtain Iset, TMS and trip time. The calculations that have been carriedout get the results of DGR setting with a pickup current range of 0.0522 – 0.0722 A.DGR will work after 2.297 seconds if the differential relay as the main protection relaydoes not work or fails and the distance relay as a backup protection does not succeed insecuring a single phase fault to ground as well.

The increasing need for electrical energy every year results in the availability of energysources is dwindling. Therefore, the need for energy conservation to streamline the use ofelectrical energy without reducing its comfort or productivity. The main factor of energyconservation is energy auditing. Plasa Telkom Teuku Umar is a company engaged intelecommunications. The convenience of employees and customers takes precedence overthis0company.0The best service0must also be followed by the efficient use of facilities. For thisreason, an electrical energy audit is needed. In this study, it was attached0to theair0conditioning0system and lighting system. It is attached to the air conditioning system andlighting system. Tools0that can be0used for measurement in the field are Lux Meter, (lightintensity measurement), Tang Ampere (electric current measurement), and Thermometer (roomtemperature measurement). The study was conducted by0calculating and comparing0electricalenergy consumption in lighting and air conditioning systems between before and after anenergy audit. Calculate the pre- and post-audit IKE (Energy Consumption Intensity) andcompare it to the IKE standard. The results of the study found energy savings of 36.06%. Fromelectricity usage of 16.86 kWh/m2/bln pre audit to 10.78 kWh/m2/mo post audit.
