This study aims to analyze the implementation of legal responsibility by goat farmers in managing waste from Etawa goat farming based on a circular economy model at Nusantara Farm, Sidoarjo. The study employs both normative juridical and empirical juridical approaches, with data collection techniques including literature review, interviews, and field observations.The results indicate that waste management is carried out through direct utilization, such as using livestock manure as organic fertilizer, selling waste, and distributing it to the surrounding community. These practices demonstrate that waste is not disposed of carelessly but rather reused, thereby creating economic and functional value.From a legal perspective, this condition reflects the fulfillment of the farmers' responsibilities in accordance with applicable laws and regulations, particularly in efforts to prevent environmental pollution. Furthermore, these waste management practices partially embody the principles of the circular economy, especially in terms of reuse.However, the current waste management practices remain conventional and are not yet optimally integrated. Therefore, there is a need to develop a waste management model based on an integrated closed-loop system to enhance the economic value of waste while ensuring more effective environmental sustainability.

This study aims to analyze the environmental impact of waste generated by the gecko processing home industry based on environmental law regulations in Indonesia. In its processing activities such as lizards and snakes. These activities produce organic waste in the form of animal organs, blood, body fluids, and other waste in the materials that are later utilized as catfish feed. The research method used is qualitative with a normative juridical approach, statutory approach, and literature study. Data were obtained from laws and regulations , scientific journal, and environmental law literature. The results of the study indicate that the disposal of waste into rivers can increase Biological Oxyen Demand and Chemical Oxygen Demand (COD) levels, cause unpleassant odors, and reduce water quality and public health. The utilization of waste as catfish feed can reduce the amount of waste disposed of, however, it still requires hygienic processing to prevent biological risks. From the perspective of environmental law, the direc disposal of the waste into rivers is not in accordance with Law No. 32 of 2009 concerning Environmental Protection and Management and Government Regulation No. 22 of 2021 concerning the Implementation of Environmental Protection and Management.

separating and shredding organic and inorganic waste. This study aims to analyze the process of shredding household waste using the Computational Fluid Dynamics–Discrete Element Method (CFD-DEM) and determine the optimal operational parameters based on variations in rotor speed. The research method uses numerical simulation with SolidWorks 2024 software for geometric modeling and Ansys Rocky 2023 R1 for CFD-DEM simulation. The rotor speed variations used are 1000 RPM, 2500 RPM, and 4000 RPM with a mass flow rate of 4 tons/hour and a simulation duration of 2 seconds. The parameters analyzed included particle mass flow rate, shredding characteristics, and power consumption. The simulation results showed that a speed of 1000 RPM produced the most optimal performance with a maximum capacity of ±4 tons/hour and a stable shredding response compared to other variations. At 2500 RPM, there were high fluctuations with low capacity (±0.6 tons/hour), while at 4000 RPM, the capacity was moderate (±1.1 tons/hour) but still did not exceed the performance of 1000 RPM. Based on these results, it can be concluded that a rotor speed parameter of 1000 RPM is the most effective condition for improving the grinding efficiency and production capacity of a hammer mill-type Depackaging machine based on CFD-DEM simulation.
