Abstract

Money politics is now considered a "custom" in the Maja community. Even in rural communities who have strong solidarity, money politics is considered to have a strong role to bind people's voices in political contestation. The purpose of this study was to determine how the public's perception of the phenomenon of money politics. in Maja Village, Maja District, Lebak Regency. The research method used is qualitative. The results of the study indicate that the people of Maja Village have different perceptions from legal norms in viewing money politics. The community considers that money politics is a form of gratitude for the votes that will be given and an approach to the community. In social action theory, Weber introduced the concept of a verstehen approach to understanding the meaning of one's actions. In this case, the Maja people build perceptions and action decisions based on their vision of the people around them and the figures they emulate.

Abstract

Used cooking oil is a waste that is produced every day and is increasing. Used cooking oil cannot be consumed again because it contains dangerous substances that will cause disease, but it also cannot be thrown away since it will pollute the environment. Therefore, it is necessary to process used cooking oil, one of which is purification using the adsorption method. The adsorption method for used cooking oil can be derived from green dregs because greens contain antioxidants which can reduce the content of dangerous substances in used cooking oil. In this study, we used variations in adsorbent mass (10 gr, 20 gr, 30 gr, 40 gr, and 50 gr) and stirring time (25 minutes, 45 minutes, 65 minutes, 86 minutes, and 105 minutes) to obtain the highest purification results. was the best and it was found that the adsorbent mass of 50 grams of green dregs and a stirring time of 105 minutes had the best results in being able to reduce the peroxide value, air content and free fatty acids. Next, the purified used cooking oil will be processed into floor cleaning liquid soap with the addition of 2 ml, 4 ml, 6 ml, 8 ml and 10 ml of pineapple peel extract. The results of the floor cleaning soap showed that the best results were 2 ml based on the alkaline number, pH and anti-bacterial test.

Abstract

Commercially competitive in the global market, bio-briquettes derived from coconut shell charcoal have been extensively manufactured and meet all standard prerequisites. Bio-briquettes sourced from different biomass materials, with calorific values that meet the criteria, have not entered commercial production. Currently, they remain in the research and development phase. One of the reasons is the suboptimal durability value of the bio-briquettes, causing the products to easily break during distribution and usage. This research aims to determine the optimal amount of binder in the production of bio-briquettes from cassava peels. This is because cassava peels have calorific values that meet the requirements and have a huge potential for commercial-scale production. This study utilizes cassava peel charcoal as the raw material mixed with tapioca binder in variations of 9%, 10%, 11%, 12%, and 13% of the cassava peel charcoal mass. The optimal percentage of tapioca binder mass was found at 9% with a durability value of 99.54%, density 1 g/cm3 and water content 5.39%.
