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.

Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.

To achieve an environmentally friendly campus, UMN operates gas engine generator with co-generation system. Waste heat from generator powers absorption chiller for air conditioning. UMN benefits clean energy sources, reduced pollution, and energy saving. The next phases rely on energy consumption reduction by applying passive design. Two towers were designed with double-skin facade. The perforated aluminum panel reduces solar heat gain on the building wall while still allows sunlight into the room for natural lighting. Lower room temperature will reduce cooling load, which will save energy. Combined with energyefficient appliances and natural air ventilation for corridors and open space, this concept saves more than half of energy consumption. Both towers were awarded the first and second winners of ASEAN Energy Award in 2014 and 2019. Various trees have been planted and produce oxygen to supply fresh air to create comfortable studying environment without air conditioning. To reduce carbon footprint, UMN provides shuttle bus and bike-sharing service. A holistic approach is implemented by recycling and conserving water with sewage water treatment and infiltration wells surrounding the campus. As part of the sustainability program, UMN has also utilized solar energy.

The Health Center (Puskesmas) is a technical implementation unit of the District/City Health Office responsible for implementing health development in a specific working area. Puskesmas Kelapa Dua is the first health center in Kelapa Dua Subdistrict, Tangerang Regency. The registration process at Puskesmas Kelapa Dua has been done manually, where patients or participants have to come and wait for a long time just to register and get a queue number for treatment. Therefore, the Patient Information and Registration System was developed for Puskesmas Kelapa Dua, Tangerang Regency, Banten. This activity aligns with the planned objectives and benefits, which are to assist Puskesmas Kelapa Dua in providing information to the community and facilitating patient registration for treatment in an easier, more practical, time-saving, real-time manner, without wasting much time, cost, and effort. This is achieved through a mobile phone-accessible application. The results were obtained from testing, including functional testing where all system functions worked well, environment testing conducted on various browsers with no issues, and User Acceptance Testing (UAT) where user satisfaction was evaluated, and the system successfully met user expectations
