Abstract

This study aims to improve the understanding of Mathematics concepts through Geoboard learning media for students with visual disabilities at the SLB-A Karya Murni Education Foundation. This research was conducted at Yayasan Pendidikan SLB-A Karya Murni, which is one of the Junior High Schools (SMP) for students with visual disabilities in Medan City, North Sumatra. In this study using the type of R&D research refers to the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The subjects in this study were seventh grade students of the SLB-A Karya Murni Education Foundation in the 2023/2024 academic year. The product draft in this study has been designed and then validated by 2 experts, namely Material Experts and Media Experts. The results of the initial stage validity test by material experts obtained an average percentage of 46.15% (Less Feasible), Stage two validity test by material experts obtained an average percentage of 88.46% (Very feasible), Stage one validity test by media experts obtained an average percentage of 47.5% (Less feasible), and Stage two validity test by media experts obtained an average percentage of 91.25% (Very Feasible). Understanding of concepts in mathematics learning is obtained from learning activities on flat building material, the results of which are effective assessment with a significant increase in learning outcomes with the category of Nominalised Gain index 0.67 <0.7 classified as (Moderate).This research produces a product in the form of learning media in the form of Geoboard. The Geoboard is feasible to use judging from the percentage obtained in each manufacturing process.

Abstract

This research aims to find out the Enforcement of Criminal Sanctions Against Protected Wildlife Trade in Sorong City To find out the obstacles in the application of Enforcement of Criminal Sanctions Against Protected Wildlife Trade in Sorong City. This type of research is normative juridical research, data sources in this research are primary data and secondary data consisting of primary legal materials, secondary legal materials, and tertiary legal materials. Data obtained by library techniques and analyzed descriptively quantitative. The results showed that (1) Positive law in Indonesia distinguishes between “wildlife” and “pets” to protect biodiversity. Based on the Regulation of the Minister of Environment and Forestry Number P.20/MENLHK/SETJEN/KUM.1/6/2018, there are 794 species of animals and 130 species of plants that are protected. Exploitation of protected wildlife is considered a criminal offense, as stated in Article 302 paragraph (1) of the Criminal Code which stipulates penalties for animal protection offenses. (2) Based on interviews with police officers in Sorong, it is known that there are law enforcement efforts against the trade of endangered animals, which involves cooperation between the Sorong Police and the Natural Resources Conservation Center (BKSDA) to ensure animal protection. This effort reflects an active role in implementing animal protection and raising awareness of animal welfare, which is part of moral norms. The effectiveness of law enforcement is also influenced by the structure, substance, and culture of law, in accordance with Lawrence Friedman's theory, as well as the five factors of legal effectiveness according to Soerjono Soekanto. This research shows that strengthening the substance of the law through criminal sanctions can provide a deterrent effect and prevent rare animal trade crimes, but structural and cultural improvements are still needed to achieve optimal success.
