Eco Enzyme is a result of organic waste fermentation, derived from leftover fruits, vegetables, sugar, and water. It was first discovered by Dr. Rosukon Poompanvong, a member of the Organic Farming Association from Thailand. Eco Enzyme serves as a versatile liquid for household, agricultural, and livestock purposes. According to an article by Vama & Chekar in 2020, eco enzyme can be utilized as an antifungal, antibacterial, insecticide agent, and cleaner. Some of its functions include being a floor cleaner, dish cleaner, and toilet cleaner.The author created a business around eco enzyme using leftover fruits. The raw materials for eco enzyme are obtained from fruits that are no longer consumable or have become spoiled. Although there have been numerous studies on utilizing leftover fruits for eco enzyme production, not many people in the community are aware of or use eco enzyme. Therefore, the author came up with the idea of a business centered around eco enzyme, both as a value proposition for utilizing leftover fruits and as a means to educate people who are unfamiliar with eco enzyme.

Waste problems that have not been resolved so far have also been experienced in the Tanjung Market area, Jember Regency. The waste problems at Tanjung Market are an ineffective management system, the accumulation of waste that is not sorted into one, and the absence of a special party assigned by the market manager to handle and control hygiene problems and waste in the market which causes a lot of waste to be scattered around the market. everywhere. Not only from the traders side but this is also caused by the visitors or buyers at the market, most of them do not have the sensitivity and awareness to be able to dispose of waste in its place. So we need an environmentally sound waste management system with 3R techniques such as converting waste into useful materials efficiently and economically with minimal environmental impact.

The application of responsibility accounting has a very important role, with the aim of evaluating work results and generating feedback so that future cooperative operations can be better. Accountability accounting can help assess financial performance so that the proper use and use of financial resources can be identified. With performance appraisal it can be known the condition of the cooperative in evaluating the results of activities so that it can be used to measure success in KUD Tani Wilis. This study aims to determine the application of profit center responsibility accounting in assessing financial performance. In this study the data used are primary data in the form of an overview, vision and mission, as well as cooperative organizational structure, and secondary data in the form of profit center accountability reports. Sources of data collection in the form of interviews and documentation with quantitative descriptive analysis techniques. The results of this study indicate that the application of responsibility accounting in KUD Tani Wilis is inadequate because it is not fully in accordance with the requirements of responsibility accounting. The results of financial performance in terms of profit center based on the analysis of Gross Profit Margin, Operating Profit Margin, and Net Profit Margin show unfavorable financial performance results. Cooperatives need to implement responsibility accounting in accordance with responsibility accounting requirements by separating controllable and uncontrollable costs, as well as providing account codes for these accounts in the accountability report so that it makes it easier for cooperative managers to control costs and see who is responsible if irregularities occur. Cooperatives must also pay more attention to the increase in cost of goods sold, and minimize production costs and operational costs as well as optimize sales/revenues and evaluate business costs or operational costs, so as to increase profits. By evaluating business costs or operational costs carried out by cooperatives in an effort to increase efficiency where economic resources can be used effectively so that costs are not wasted so that the profits obtained are more optimal and can improve the financial performance of cooperatives.

The purpose of this study is to find out the meaning of the dragon in Marjan 2023 advertisement "Baruna Sang Guardian of the Ocean" by using a qualitative descriptive theory approach and Roland Barthes' Semiotics theory which interprets something based on the denotative and connotative meanings of signifiers, signifieds and signs that exist in an object. The results of this study indicate that the dragon in the ad refers to a social disaster caused by humans who often throw plastic waste into the ocean.

Background: Waste that continues to accumulate every year is an unresolved environmental problem at the regional to global level. This problem can actually be overcome by applying good waste management according to its type (organic and inorganic). However, waste management is still rarely practiced in the community, for example for residents of Tegal Sari Village RT 1 and 3, Satui District, Tanah Bumbu Regency. The waste segregation, disposal, and processing system in the village is not optimal. Objective: Therefore, the Desa Relasi program aimed to increase the knowledge and awareness of residents in managing organic and inorganic waste through Takakura composting and inorganic crafts. Methods: The program was formed based on the results of problem priorities obtained during PBL through identification and analysis of health problems in the village by collecting secondary and primary data (with interviews and questionnaires). Results: Activities in the program are in the form of counseling, cadre debriefing, demonstration, and practice. The evaluation instruments used were pre-post test questionnaires (I and II), observation, and evaluation through chat. Based on the results of the knowledge test during counseling, 72.73% of residents experienced an increase in knowledge, 22.73% were stagnant, and 4.55% experienced a decrease (pre-post test I). While in post-test I - II, 77.72% experienced an increase, 18.18% did not experience an increase or decrease, and 4.55% experienced a decrease. Conclusion: There was an increase in knowledge in most participants regarding organic and inorganic waste management. Therefore, it is hoped that Tegal Sari Village residents will be able to apply good waste management so that it can produce use, sale and aesthetic value and advance the village.
