Abstract

Continuously variable transmission (CVT) technology is currently something that is very commonly used in motorcycles for various reasons of practicality in use. This encourages the importance of CVT technology literacy in motorcycles to emerge in this context, because the CVT system has characteristics that inherently support fuel efficiency. CVT allows riders to enjoy smooth transmission ratio changes without the need for manual gear shifting. This is an advantage especially in urban traffic situations that often involve stop-and-go patterns, where the CVT system can keep the engine operating at an efficient speed. However, in order for the benefits of CVT to be felt to the maximum, riders need to understand how this technology works. CVT technology literacy includes knowledge of how to use the CVT system optimally, avoiding riding styles that can put excessive stress on the transmission, and understanding the maintenance needed to maintain CVT performance. Riders who are educated in CVT technology will apply fuel-efficient riding techniques, such as avoiding sudden acceleration or unnecessary braking, which will not only increase fuel efficiency but also extend the life of the CVT. In addition, regular maintenance, such as checking and replacing the CVT belt according to schedule, can prevent premature damage and ensure that the motorcycle continues to operate at its best performance. With adequate literacy, riders can not only save fuel and operational costs, but also support environmental sustainability by reducing emissions. Therefore, increasing public understanding of CVT technology is a strategic step to create more technologically aware and responsible motorcycle users.

Abstract

The problem of dust pollution at the service partner "Concha Handycraft" is at the core of program activities. Controlling dust from its source is the main goal, namely replacing blower style vacuum cleaners with centrifugal type vacuum cleaners. The centrifugal type was chosen because it has a simple shape, the motor is separate from the fan, so the motor is protected from dust. The activity method begins with designing, purchasing materials, manufacturing in the workshop, testing, minor repairs, application and assistance. The results obtained are that the centifugal model vacuum cleaner that has been applied has advantages. The electrical power used from previously 260 watts to 120 watts. Working time can also increase because the motor used is a DC motor so it doesn't heat up quickly. If you use a blower model, the electric motor heats up quickly because it gets dust and needs to be cooled. The ability to suck up dust is also increased, with a fan at a 30 degree angle the ability to suck up and throw out is balanced. By using a centripugal model vacuum cleaner, 95% of the dust produced by the grinding machine can be sucked into the dust collection chamber.  Concha Handycraft partner SME owners and employees are very happy with the new machine, so they can be more productive at work, and stay protected from exposure to dust in the workplace.

Abstract

Fossil energies as un-renewable energies have been getting depletion. Therefore, the use of alternative energy should be raised. One of the alternative energies is solar energy. Solar energy does not pollute the environment and is categorized as a renewable energy which is free and plentiful.   In this research, the solar energy was used to heat water by operating granite absorber solar collectors. The water was flowed naturally from a higher tank and adjusted using a valve fitted at the outlet of the collector.  The volumetric rates of the water were 200, 250 and 300 cc/minutes. Two identical solar collectors with an overall dimension of 0,8 m x 1 m x 0,1 m were placed under the sun and faced to the North with an inclination angle of 15°. One collector contained 5 parallel pipes and the other comprised 7 parallel pipes.  Data obtained in this research are glass cover temperatures, an ambient temperature, absorber temperatures, inlet and outlet water temperatures, and water volumetric rates. The results show that the 7 parallel pipe collector products higher outlet water temperature and energy than the 5 parallel pipe collector. Consequently, in the process of energy removal/discharge, the heat stored in the 7 parallel pipe collector runs out quicker.

Abstract

Clean water is a requirements of very important human life. Indonesia is a maritime country that has many islands surrounded by ocean, had a decreased clean water problem. One of the method to be used for obtain clean water is sea water distillation process. One of the most important tools is absorber distillation. occurs heat transfer from the absorber to the sea water causing, rising sea temperatures cause sea water to evaporate. The rising temperature of the sea water increases the amount of evaporation that occurs. The more the amount of evaporation generated will increase the number of fresh water produced. Increased seawater temperatures by increasing the temperature absorber, so it needs to be analyzed shape of the absorber which one can be produce more clean water than the others, a conclusion of the study indicated that solar distillation plat shape with a huge wave absorber produces more clean water than the others , the average amount of water that is more of 908 ml, compared with a small wave absorber plate only produce 764.4 ml  average a day and a flat plate absorber only produce 599 ml average a day, it is not independent of heat absorption by absorber, solar distillation plat shape with a huge wave absorber absorbs more heat than the other two absorber plates, this has resulted in solar distillation  shape with a huge wave  absorber plate  very well produce more water than the otehrs.
