Since Corona Virus Disease (COVID) – 19 is considered a pandemic by the World Health Organization (WHO), governments, and communities, worldwide trying to prevent transmission and reduce the number of deaths caused by the virus. One method of preventing transmission is spraying disinfectants using certain chemical compounds. However, chemicals can also hurt the environment and humans themselves if the doses used are not by existing standards. An alternative disinfectant method that does not use chemicals and is environmentally friendly, namely by using the UV (Ultraviolet)-decontamination method, UV-C rays. This research aims to find out the results of UV irradiation from UV-C lamps in theory and measurement. Then, the optimal placement of a fixed - UV lamp system to obtain an effective disinfectant dose and the length of time it takes to reach the target dose prevent the spread of the COVID-19 virus. The methods include theoretical calculations and data measurements to see the results of UV radiation irradiation on UV-C lamps and look for correlations between the two to find the conversion value. Moreover, with the help of DIALux Evo 9.2 software to find out the radiation value from the conversion equation, see the optimum UV dose spread, and reach the desired dose target time. The result is that there are differences in the results of UV irradiation on UV-C lamps with the efficiency of lamps and ballasts as well as on the measurement method that affects UV-C radiation, but according to field conditions and does not affect the actual application. The number of lamp placements and the dimensions of the room affects the dose spread. Moreover, the minimum time to achieve the target dose in the case study is 29 minutes using six placements of UV-C lamps with two lamps each at the six placement points.

Nowadays, fulfilling the needs of human life requires costs. If the daily needs are under control, then the expense spent to meet the daily needs will also be controlled. In everyday electricity usage, the lights may turn on when the user does not need them. This incident resulted in a waste of electricity and costs. This research designs a Light Emitting Diode (LED) light control system using a microcontroller and smartphone application. The features available in the lamp control application consist of Off and On, Timer, Schedule, Electrical Energy Monitoring, and Automation based on Electricity Billing Budgeting. The tools and software used in the design of the lamp control are: Node MCU ESP8266 version 2, SRD-05VDC-SL-C relay module, ACS712 current sensor, Arduino IDE, MIT App Inventor, and ThingSpeak. The time delay from pressing the ON/OFF button on the smartphone until the light turns on is about 1-6 seconds. The error value for calculating the lamp power with the ACS712 current sensor against the lamp power from the specifications on the light box is 1.3%.

This paper aims to design a receiving antenna for harvesting energy using the wireless energy transfer method based on the ultra-high frequency (UHF) band. The study was conducted by comparing four types of the receiving antenna design. A mathematical and experimental analysis has been done to evaluate the performance of the designed antennas. A Yagi-Uda antenna is utilized as the transmitter. The results show that the zig-zag type antenna has the best performance. It can receive electromagnetic energy from a transmitter with maximum efficiency is 0.1% for the receiving antenna volume of 0.34 cm3. The proposed method can meet the energy necessity of an implant device with a charging time of approximately 21.61 hours for the 700 mAh rechargeable battery capacity. As our preliminary conclusion, based on our results, this proposed method can be used as a reference for the practice in the WET field and the medical and restricted areas in the electromagnetic energy harvesting case.

Green building is the concept of designing, building, operating, and maintaining buildings that pay attention to the use of natural resources, indoor air quality, and the health of the occupants. This green building is the choice in responding to the issue of limited non-renewable energy. To monitor the environmental conditions of green buildings, a sensor system is needed to maintain environmental conditions according to standards. This study aims to design a sensor system to monitor environmental conditions in Universitas Multimedia Nusantara. A real-time monitoring system is needed to maintain the green building environment's condition. The results of the study succeeded in designing a real-time monitoring system for green building environmental sensors, especially web-based classrooms using the NodeMCU ESP8266, DHT22 Sensor, and LDR Sensor. The difference in readings between the monitoring sensor system and the environment meter for lighting levels, temperature, and humidity respectively is 0.67 lux, 0.9°C, and 5.8%RH.

PT Pertamina (Persero) as the vanguard of the archipelago's energy has committed to finding and developing new and renewable energy sources to support national energy independence and sovereignty. One of the concrete steps taken by PT Pertamina through the Cilacap Processing Unit IV is to build a Solar Power Plant. One of the strategic solar power plant construction sites in an empty land area close to the 500 kV Adipala Sutet Power Network is located in Cilacap regency with an average global horizontal irradiation (GHI) value of 1908 kWh/m2. With this value, the installation of solar rooftops is the right solution to support electricity production using renewable energy. The electricity load consumption from the city in one year is 1785.6 KWh and is currently entirely supplied by PLN. In this study, a Solar Power Plant design was carried out on vacant land around housing that can be produced in one year. The design and calculations were carried out using the help of PVSyst and RETScreen software. From the simulation results, the results obtained are a Solar Power Plant that has been designed to produce 463 kWh per year which can meet 25.9% of electricity needs at the design site with a Solar Power Plant performance ratio of 85.74% where Solar Power Plant can produce electrical energy of 1531 KWh per year.

The growth of the number of interconnected wireless devices such as the Internet of Things (IoT) is continuously increasing across various sectors, including smart buildings, smart offices, smart cities, and others. According to estimates, by the year 2030, there will be at least 50 billion devices interconnected through networks. The escalating number of uncontrolled wireless devices can lead to various issues such as interference, collisions, and data loss, resulting in an overall decline in network system performance. This study aims to propose a scenario as an alternative solution to optimize the overall network performance in the system by assigning channels to each interconnected wireless pair to reduce the impact of interference. This research indicates that the proposed method successfully enhances the system throughput performance by 39.75% compared to the condition where all wireless pairs operate on the same channel, thereby outperforming several other comparative methods.
