Plastic waste is the main cause of environmental pollution. It is necessary to research the design of the Injection Molding machine to process plastic waste. This study describes the design concept of a vertical type Injection Molding machine prototype by considering the factors to be utilized by small-scale plastic recycling businesses. The design stage starts from the identification of component requirements to the design of 3D drawings. The results of this study obtained a prototype design of a Vertical Injection Molding Machine. The embodiment of the design is not only determined directly by the design team and the manufacturing team, but is obtained from customer requests described in the technical specifications. At the concept design stage, there are 5 sub-functions and each function has 3 to 4 options. From the combination of these sub-functions and options, 3 assembly sketches were obtained so that 3 alternative design concepts were obtained. From the results of the concept assessment, design concept C was chosen from several alternative concepts.

A vortex turbine is a turbine that operates by utilizing a vortex flow as a drive for turbine blades which then the turbine shaft is connected to a generator to convert shaft mechanical energy into the form of electrical energy. In this study a test will be carried out on a vortex turbine with a head of 1 m, a flow rate of 0.12 m3/s. In the testing process, 3 types of blades will be used, namely straight blades, curved blades and finned curved blades. After testing, it can be concluded that the highest power is found in the curved blade of 959.08 Watt and then the finned curved blade is 714.38 Watt, while the lowest power is found in the straight blade type of 582.48 Watt. The resulting rotation can be seen in the graph below. The highest rotation is found in the finned curved blade of 540.00 rpm and the next is the curved blade of 517.67 rpm, while the lowest rotation is found in the straight blade type of 510.67 rpm. For the efficiency of each metal blade, it can be seen that curved blades are still the highest followed by curved blades with finned blades, the lowest being straight blades with salty blade efficiencies of 98%, 73% and 59%

The distribution of PLN electricity to remote areas has not been achieved so there are other alternative resources needed, for example solar power plants. The aim of this research is to design and analyze the potential for a solar power plant with an off-grid system that can be used to supply residential homes when PLN power goes out. This solar power plant is designed for a load of 17 kwh / per day, the efficiency (ηinv) of the inverter is 93%, the efficiency of the battery block is ηBAh = 85%, the DC system voltage is chosen as 48 V. The solar power generation system designed in this research is an off system -lattice. The main components were chosen based on the calculation results for the number of panels of 3563 Wp, with a total storage battery of 1172 Ah. If you use 48v/160ah Lithium batteries connected in parallel using 7 batteries with a charging time of 7.3 hours, minimum scc current of 74 Ah, inverter current of 41.6 Ah with a panel tilt angle of 15 degrees.

This study is an experimental research that investigates the effect of varying solar panel tilt angles (180°, 15°, 30°) and adding an 80% darkness level glass film layer on power and efficiency. The study compares the results with and without the glass film for each tilt angle. The research methodology employed includes literature review and experimental development. The literature review provides a foundation for understanding the fundamental theories of solar panels, their working principles, and the impact of tilt angle on power and electrical efficiency. The results indicate that the tilt angle of solar panels significantly affects power and efficiency. The solar radiation received per unit area for each tilt angle (180°, 30°, 15°) is 920.3 W/m², 1002 W/m², and 1092.5 W/m² at 10:00 WIB, respectively, with the highest radiation observed at a 15° tilt angle. The power input to the solar panel without glass film for each tilt angle (180°, 30°, 15°) is 635 watts, 691.38 watts, and 753.82 watts at 10:00 WIB, respectively, with the highest power recorded at a 15° tilt angle. The efficiency of the solar panel without glass film for each tilt angle (180°, 30°, 15°) is 50.29%, 46.96%, and 53.46% at 14:00 WIB, respectively, with the highest efficiency achieved at a 15° tilt angle
