Abstract

At this time in the process of sweeping the road still using traditional tools by janitors, for example broom sticks. One of the technologies that began to develop was the Street Sweeper machine. This Street Sweeper is a tool to help alleviate the work of janitors in terms of road sweeping. Sweeping the highway using the Street Sweeper is one of the main steps to accelerate the process of sweeping the highway with rapid traffic flow. The working principle of this machine is by utilizing thrust from humans, by means of a machine being pushed and directed to the garbage scattered on the road. Therefore it is very appropriate to use Street Sweeper to sweep the road compared to using manual tools because it can save work time

Abstract

Wind turbines convert the kinetic energy in wind into clean electricity. When the wind spins the wind turbines blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator. Wind electric systems are one of the most cost-effective home-based renewable energy systems with zero emissions and pollution. Many factors that influence the performance of wind turbines such as wind speed, blade shape, and number of blades. In Generator, Coil number of turn (N) also influence performance of wind turbine. Manufacture of wind turbine prototype as a learning medium to facilitate students in understanding the concept of wind electric system. Results of the test prototype wind turbine if the wind speed the greater the resulting voltage will be higher, the Coil number of turn (N) also affects the voltage generated.

Abstract

Biogas is a gas fermentation of organic materials which contain most of the gas methane, carbon dioxide, few of carbon monoxide, hydrogen, hydrogen sulfide, nitrogen and ammonia. One of technological development of biogas production is anaerobic reactor. The processing of biogas technology is influenced by several factors, such as temperature and humidity. In this study, temperature is adjusted using a spiral system and biogas reactor which submerged into the water. The temperature of water can be controlled. In another case there is reactor without temperature setting as a comparison. The observation shows that the reactor in the water produces most biogas, reactor spiral in second place and reactor without heating in the last one.

Abstract

Pembangkit Listrik Tenaga Gelombang Laut -Sistem Bandulan (PLTGL-SB) yang rancang-bangunnya berbentuk ponton di tempatkan mengapung di atas permukaan air laut, dan PLTGL-SB tersebut akan mengikuti gerak/arus gelombang sesuai dengan frekwensi gelombang laut, sehingga menyebabkan posisi PLTGL-SB selalu bergerak terombang ambing sesuai dengan alur gelombang. Karena gerakan terombang ambing ponton yang terus-menerus tersebut menyebabkan ayunan bandul yang akan dirubah jadi putaran generator dalam hal ini ada empat bandul, sehingga PLTGL-SB mengeluarkan Energi/Daya Listrik. Gerakan bandul yang bergoyang dirobah dengan menggunakan sistem trasmisi menjadi putaran yang dapat memutar dinamo/generator, dan generator yang digunakan adalah jenis putaran rendah 3 Phase AC dengan daya 500 Watt pada putaran 1400 rpm.
