The Role of Karang Taruna in Increasing Civic Engagement through Mutual Cooperation Activities

This article was written to find out the role of cadets in increasing citizen involvement through mutual aid activities. This study was conducted using a qualitative descriptive method with data collection techniques through literature studies and interviews. The results of the study show that the role of cadet corals as a driving organization in mutual aid activities is indeed very important. Karang taruna as an important element in society that is believed to have high ideas, creativity and innovation which is expected to be able to create changes from what is done and one of the community organizations that can welcome the realization of social development, welfare and harmony in society. Karang taruna through a joint program, namely mutual cooperation, is able to encourage every element of the community to take their respective roles in the success of the program that has been planned so that it will have a big impact on the development of social life in a village. Through mutual cooperation, cadets can embrace the surrounding community to play a maximum role in development efforts and improve community welfare. Community participation in mutual cooperation will foster a sense of family, togetherness and good cooperation so as to increase community involvement in social activities carried out.Keywords : karang taruna, civic engagement, mutual cooperatio

Analisis Eksergi Pada Kolektor Surya Pelat Datar

The use of Liquefied Petroleum Gas (LPG) as an energy source for cooking in Indonesia is estimated at 63.1 MBOE in 2020. One form of LPG utilization is generally heating air, both conventional and using water heaters. Limited domestic supply requires substitution to other types of energy specifically renewable energy. The intensity of solar radiation reaching the earth at 1367 W/m2 provide great potential for the utilization of solar energy through solar water heater as a source of water heating. The study was conducted with serpentine tube arrangement and using 0.5 liters/minute continuous flow rate which is analyzed by the 2nd law of thermodynamic. This study also aims to analyze the effect of solar intensity to differences temperature of collectors, the amount of exergy gain for heating the water and the effect of solar intensity to exergy destruction. From the research, it was found that the higher solar intensity, the higher the temperature difference between input and output and exergy destruction. The highest efficiency is 3,2%. The low efficiency of collectors is caused by the higher exergy destruction
