Abstract

Supervision is one of the systematic activities of environmental management. In the latest provision, environmental management supervision is regulated in the Ciptaker Law and several government regulations regarding risk-based business licensing. This also has implications for environmental management efforts in businesses and / or industrial activities, especially those with a high level of risk, which requires environmental approval as one of the components of the permit. Based on this, the formulation in this study is how effective the implementation of DLH supervision on industries that have a high level of risk in Boyolali Regency. This Legal Research uses empirical methods with a descriptive approach and data collection techniques with interviews. Based on the results of the study, it was found that many high-level industries in Boyolali Regency do not yet have an AMDAL as an environmental approval document as stipulated in laws and regulations. Of course, this is a problem because it is contrary to laws and regulations which are also a benchmark for the lack of effective supervision carried out by DLH. The lack of effective supervision by DLH is due to several inhibiting factors such as the lack of PPLHD and the lack of compliance of those in charge of industrial activities. However, in addition to these obstacles, several efforts have also been made to improve the effectiveness of supervision.

Abstract

Elementary school students tend to rely on memorizing formulas to solve mathematical problems. They do not yet understand the visual meaning of mathematical concepts, which affects their ability to represent ideas well. This study seeks to investigate students’ abilities to use mathematical representation when solving problems involving 2D geometric shapes. The study employed a qualitative research approach using a case study design. Data were collected through interviews with the classroom teacher and ten students at SDN Brangkal 1 and analyzed using thematic coding techniques. The findings revealed that most students continue to rely on memorizing formulas without grasping the visual meaning of 2D shapes. They seldom use diagrams, rarely verify answers, and struggle to articulate the reasoning behind their problem-solving steps. In addition, the students demonstrated limited verbal representation skills, often providing brief, unexplained responses and showing little habit of expressing their thought processes. These results suggest that students' competence in mathematical representation within the domain of geometry remains low. The findings underscore the need for instructional strategies that integrate visual, symbolic, and verbal representations, and cultivate habits of reflection and communication in primary school geometry education.
