Abstract

Wind turbines work by converting wind into electrical energy. The moving turbine is exposed to the kinetic energy of the wind, while simultaneously driving a generator that can produce electricity. Wind electric energy is a simple, economical and non-polluting energy system. Several factors influence the performance of a wind turbine, such as wind speed, number of angles, and angle shape. The amount of wind power that can produce several coil (N) revolutions also affects the performance of the turbine. If the wind used is large, the pressure or movement made by the turbine will also be greater, so that the number of rotations produced will also increase, thus producing large amounts of electrical energy. The aim of this research is to help students think critically about natural science material. Carrying out this research is expected to be able to find out the character of students in learning, how students think about the material presented, and to find out how teachers provide natural science learning by involving learning media as a tool to help understand the material. The research method developed is Research and Development (RnD). The research model we use is to show how the media works to help explain electrical energy science material.

Abstract

This study examines the implementation of an economic ecobrick program conducted by community service students (KKN) in Sumur Batu Village, Teluk Betung Utara District, Bandar Lampung. The program aimed to reduce plastic waste while fostering community empowerment through creative and environmentally friendly activities. Using a qualitative descriptive approach, data were collected through. Interviews, observations, and documentation during a 30-day period of engagement. The findings show that community participation, particularly from local women’s groups (PKK), was highly enthusiastic. Several creative products were successfully produced, including keychains, headbands, and decorative mirrors made from household plastic waste, as well as compact ecobrick bottles that served as simple building prototypes. Environmentally, the program contributed to reducing plastic waste and raising community awareness about sustainable waste management. Economically, the products demonstrated initial potential as marketable items, although their development remained limited by the availability of raw materials and variations in product design. In conclusion, the ecobrick program not only functioned as a solution for plastic waste management but also as a means of fostering local creative economy initiatives. The program’s sustainability requires continued support from community organizations and local government
