Abstract

Street lighting is needed to ensure road users' smooth running and safety. Lack of light will create a high risk of accidents and crime on the road. Many areas in Indonesia in general and West Sumatra in particular, mainly rural areas, still need street lighting due to the need for regional capacity to provide lighting on public roads. This activity implemented street lighting in Nagari Lagan Mudik Punggasan, Linggo Sari Baganti District, Pesisir Selatan District, West Sumatra Province. A total of five light units have been installed in four different locations. Installation of lights using a pole made of wood as high as 4 meters on the 20 KV distribution electricity post and the welcome board of the village. The lights work automatically and can be active when dark and off when bright. The lamp's working principle utilises solar panels, which produce electricity during the day. The source of electrical energy used by the light comes from a battery that a solar panel has charged. This system is expected to overcome the village's lack of street lighting and use clean, environmentally friendly energy sources.

Abstract

The development of flying robot technology or Unmanned Aerial Vehicles (UAVs) requires innovations in materials that are lightweight, strong, and environmentally friendly. This study aims to design and manufacture flying robot propellers using composite materials with an epoxy resin matrix reinforced with natural fibers from snake plants (Sansevieria trifasciata). Sansevieria trifasciata fibers were chosen for their potential as an alternative material with good specific strength, abundant availability, and light weight. The propeller was manufactured using the hand lay-up method, followed by mechanical testing to determine the characteristics of the composite material, including tensile and impact tests. In addition, functional testing was conducted to measure the performance of the propeller in generating thrust. The results of the study show that Sansevieria trifasciata fiber composites have sufficient mechanical properties to be used as propeller materials for small-scale UAVs. The thrust performance produced is comparable to that of similar commercial propellers, indicating that natural fibers can replace conventional synthetic fiber-based materials and support more sustainable technological advances.
