Currently, buildings are responsible for 32% of the world’s energy consumption, with the most massive energy-consuming device in facilities being the refrigeration system. Photovoltaic is an alternative source of energy without causing environmental damage. Solar Refrigeration is an attractive solution because when there is much solar radiation, peak thermal energy is generated, and a lot of cooling capacity is needed. In this research, the amount of PV modules used as the LiBr-H2O Absorption Refrigeration System’s primary energy source is investigated. PV modules have a dual function, namely as a producer of electric power and producing thermal waste, both of which can be used as energy sources to drive this refrigeration system. In this thermal waste, two thermal sources, namely thermal convection and thermal radiation, accumulate to activate heat exchange at the LiBr-H2O absorption refrigeration system’s generator side. For electrical power from the PV module, it is used to run the air heater to increase the temperature until it reaches the optimum point for hot water supply between 65 to 70 oC. The results are that at least 100 modules of 100Wp Monocrystalline PV Module are needed to drive the LiBr-H2O absorption refrigeration system. Still, it is limited to 15.00, after which the energy source is switched back to electricity from PLN because, after 15.00, many PV modules are required and takes up a large enough space.

Piezoelectric is one of the generators of electrical energy when the material is deflected due to pressure. Research has been done on the potential of the fins on the electric voltage produced by piezoelectric. The research method used is to observe the piezoelectric vibrating due to the flow of air passing through the bluff body resulting in a deflection of the fins to strike the piezoelectric and measuring the electric voltage. Changes in the speed of fins installed with piezoelectric dimensions, namely fin one length 12 cm and width 10 cm, fin two length 12 cm width 10 cm and tip width 12 cm, fin three length 12 cm, width 10 cm and tip width 14 cm. The research was conducted in a mini wind tunnel with wind speeds of 5 m/s, 7 m/s, and 9 m/s with a piezoelectric distance to the rhombus bluff body is 80 mm. The results obtained are fin 1 with a speed of 9 m/s produces an electric voltage of 5.15 volts, fin 3 with a speed of 9 m/s produces an electric voltage of 5.46 volts, and fin 4 with a wind speed of 9 m/s has the highest voltage value, namely 5.58 volts. The airflow as it passes through the end of the bluff body section causes the fin to move up and down. The greater the turbulence that occurs, the greater the air hitting the piezoelectric surface so that the value of the electric voltage becomes high.

Every school must have a cleaning staff whose job is to care for and maintain the cleanliness of the school building. At SMKN 2 Bawang, the building is spacious and separated between buildings, so collecting waste requires a lot of time and effort. An ineffective process occurs when the cleaning staff collects waste in a circular path. Automating garbage collection using a line follower robot with PID control and the blynk application to start and stop as well as a predetermined path at a particular gathering point, can save energy and time for cleaning staff. The tuning value for each PID Control constant P=0.2, I=0.3, and D=0.06 can smooth the robot's movement with the L298N motor driver. It is decided by the Arduino UNO microcontroller and wireless connection using NodeMCU (ESP8266) for direction taking. The reading sent by the infrared sensor with analogRead mode when dimmed is in the range of 175~270, and the maximum reading value of the sensor is 940~950. The decision to turn follows a predetermined line when the sensor is below 175, according to which the sensor hits the line. The robot will stop running when the ultrasonic sensor finds an object or obstacle less than 15 cm in front of it.

Energy use in health buildings is inevitable due to building functions that must protect specific equipment or parts. One of the health buildings, namely the Indonesian Red Cross (PMI) building, serves to draw people's blood. The use of artificial ventilation must be used to support the function of the PMI building. The study aimed to determine the use or energy consumption of the Indonesian Red Cross (PMI) building in the Wonosobo Regency. The study used the field measurement method for one day. The data collection method also uses the observation method to describe the space and activities in the building. Data analysis uses graphs and compares the outside and inside of the building. AC specifications are also displayed to know how much energy is used. The results showed that the energy consumption of air conditioning in the Wonosobo PMI building was not too large, considering that only specific spaces were used. The outside area is quite remarkable and supports the AC setting, which is not too strong.
