Abstract

Tujuan dari penelitian ini adalah mendeskripsikan pemahaman konsep matematika siswa SMA ditinjau dari self efficacy khususnya pada materi matriks. Penelitian ini adalah penelitian deskriptif kualitatif dimana data utama pada penelitian ini adalah hasil tes pemahaman konsep matematika, angket self efficacy dan wawancara. Subjek penelitian yaitu siswa dengan self efficacy tinggi, sedang dan rendah yang kemudian diberi tes pemahaman konsep matematika. Penelitian dilakukan dengan wawancara terhadap hasil tes siswa dan melakukan triangulasi metode. Hasil penelitian ini menunjukkan bahwa pemahaman konsep matematika siswa dengan self efficacy tinggi sudah baik dengan menguasai indikator pemahaman konsep yaitu menyatakan ulang sebuah konsep, mengklasifikasi objek menurut sifat-sifat tertentu, menyajikan konsep dalam berbagai bentuk representasi matematis, menjelaskan keterkaitan antara konsep satu dengan konsep lainnya dan menerapkan konsep dalam pemecahan masalah. Sedangkan siswa dengan self efficacy sedang menguasai indikator menyatakan ulang sebuah konsep, mengklasifikasi objek menurut sifat-sifat tertentu dan menyajikan konsep dalam berbagai bentuk representasi matematis. Dan siswa dengan self efficacy rendah hanya menguasai indikator menyatakan ulang sebuah konsep.Kata kunci: Pemahaman konsep matematika; self efficacy. AbstractThe purpose of this study is to describe the understanding mathematics concepts of senior high school students' in term of self-efficacy, especially in matrix. This study is descriptive qualitative that the main data of this study are test, questionnaire, and interview. The research subjects is senior high school students’ with many categories such as high, medium, and low in self-efficacy. Then, the researcher give test about the understanding mathematics concepts. The researcher is doing interview and triangulation method to the students. The results of this study indicate that the students' understanding of mathematics concepts with high self-efficacy is good by mastering the conceptual understanding indicators, such as restating a concept, classifying the objects according to specific categories, presenting concepts in various forms of mathematics representation, explaining the relationship between one concept and another concept and applying some concepts in problem solving. Meanwhile, the students with medium self-efficacy are mastering indicators of restating a concept, classifying the objects according to specific categories and presenting concepts in various forms of mathematics representations, and the students with low self-efficacy are only mastering the indicator of restating a concept.Keywords: Self efficacy; understanding of mathematics concepts.

Abstract

Thematic learning is considered as efficient as the students taught learn in coherent context and holistic way, as well as associate the concepts they learnt with their surrounding and real-life examples. The aim of the study was to identify the effectiveness of the problem-based thematic learning module prototype to improve students' critical thinking skills. This research and development were conducted based on Borg and Gall model. The module effectiveness was tested using pre-experimental design. The sampling technique used was cluster random sample which employed as many as 33 students in which the data collection technique used was test. The data gained was analyzed using paired sample t-test. The results showed that the students’ post-test score of critical thinking skills were significantly differed from their pre-test score. Therefore, the developed module can improve student critical thinking skills effectively. Moreover, it is suggested that teacher should apply a mixed method of teaching as it helps to strengthen students’ critical thinking skills.

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.
