Abstract

There is a big difference between the mathematics problems taught in school and the mathematics that exists in society. As a result, educators face difficulties in modeling formal mathematical concepts with mathematical problems that occur in everyday life. By connecting mathematics learning with culture it will help the learning process. This will make it easier for educators to understand the topics being studied because they are relevant to everyday life. The aim of this research is to explore the concept of geometry in the Muhammad Cheng Hoo Purbalingga mosque. Data collection methods use interviews, observation and documentation. The camera is the tools and materials used. The data presentation is given in the form of images, along with a description of the ethnomathematics values that exist in the mosque. This research shows that the Muhammad Cheng Hoo Mosque in Purbalingga combines three cultural elements, namely Chinese, Arabic and Javanese. The results of this research show that the Muhammad Cheng Hoo mosque contains geometric elements, namely flat shapes, spatial shapes and transformations. This research is recommended for use as mathematics learning material. Keywords: Mathematics, Ethnomathematics, Muhammad Cheng Hoo Mosque

Abstract

Matematika kerap kali dianggap sebagai mata pelajaran yang sulit oleh peserta didik. Untuk mengatasi tantangan ini, model Flipped Classroom hadir sebagai inovasi untuk meningkatkan keterlibatan siswa melalui pembelajaran mandiri sebelum tatap muka di kelas. Model ini menempatkan siswa sebagai subjek aktif dengan mempelajari materi terlebih dahulu secara mandiri sebelum kegiatan pembelajaran berlangsung. Namun, efektivitas model ini dalam konteks matematika masih menunjukkan hasil yang bervariasi, sehingga diperlukan kajian lebih mendalam. Penelitian ini bertujuan untuk mengkaji sejauh mana efektivitas model Flipped Classroom diterapkan dalam pembelajaran matematika dengan menggunakan pendekatan Systematic Literature Review (SLR). Dalam penelitian ini, data dikumpulkan melalui publikasi ilmiah yang diterbitkan dalam delapan tahun terakhir, yaitu pada rentang tahun 2018 hingga 2025 melalui database seperti Google Scholar, ScienceDirect, dan SpringerLink, dengan fokus pada efektivitas, dampak, serta faktor keberhasilan model Flipped Classroom dalam pembelajaran matematika. Berdasarkan hasil analisis, implementasi model Flipped Classroom terbukti efektif meningkatkan pemahaman konsep, kemampuan berpikir kritis, dan keterampilan dalam memecahkan masalah bagi siswa. Selain itu, keberhasilan model ini dipengaruhi oleh kesiapan siswa, akses terhadap teknologi, serta strategi implementasi guru. Penelitian ini diharapkan dapat menjadi alternatif strategi pembelajaran yang inovatif dalam meningkatkan kualitas pembelajaran, serta menjadi rujukan bagi pendidik dalam mengoptimalkan penggunaan model Flipped Classroom dalam pembelajaran matematika.

Abstract

The purpose of this study is to explore and understand the legal arrangements related to criminal defamation through social media, which are reviewed based on Law Number 19 of 2016 concerning Electronic Information and Transactions (ITE), as well as analyzing the application of the law against perpetrators of criminal defamation through social media. The research method used in this research is the normative juridical method, which refers to theoretical and normative legal analysis based on applicable laws and regulations. The discussion results show that the legal regulation of criminal defamation through social media has been regulated in Article 45 paragraph (3) of the ITE Law, which regulates criminal sanctions for perpetrators who intentionally and without the right to disseminate information or electronic documents containing insults or defamation. The application of the law related to criminal defamation on social media can also be seen in court decisions, for example, in the Decision of the Rokan Hilir District Court Number 649/PID.SUS/2019/PN-RHL. In the verdict, the Defendant was found guilty and sentenced to imprisonment and a fine by the applicable provisions. The results of this study imply that ITE law provides a strong foundation for dealing with criminal defamation on social media. The application of the law has been proven through court decisions based on the provisions of the current law. This shows the importance of supervision and law enforcement against behavior that harms others through social media to prevent similar criminal acts in the future.

Abstract

Traffic violations are a persistent issue in road traffic systems globally, including in Indonesia. Despite the enforcement of traffic laws, violations remain prevalent across various regions. This study focuses on the effectiveness of applying criminal fines for traffic violations in the jurisdiction of the Rokan Hilir Police Station and examines the factors that influence these violations. The purpose of this study is to explain the effectiveness of applying criminal fines for traffic violations in the jurisdiction of Rokan Hilir Police Station and explain the factors that influence the occurrence of traffic violations in the jurisdiction of Rokan Hilir Police Station. The results of the first study show that the application of criminal fines for traffic violations at the Rokan Hilir Police Station to date is practical, and this is to the applicable rules by Law Number 22 of 2009 concerning road traffic and transportation. Many traffic violations that occur in the jurisdiction of the Rokan Hilir Police only impose criminal fines, so in the future, imprisonment with the maximum threat must also be applied to traffic violators; this is considering that only the imposition of criminal fines has not provided a deterrent effect on violators. We can see this from the increase in violations that occur every year. The criminal fines imposed have not been able to reduce the level of traffic violations that existed previously in the Rokan Hilir Police jurisdiction, even though they have always been applied to traffic violators in the Rokan Hilir Legal Area. Second, the factors that influence the occurrence of traffic violations in the jurisdiction of the Rokan Hilir Regional Police, among others, are human factors, vehicle factors, and road condition factors.

Abstract

Based on the setting for determining criminal policies that are in accordance with the values of people's lives, the setting for determining criminal policies is contained in the Criminal Code as general provisions and in the special criminal provisions of Law No. 35 of 2009 as a special crime that regulates narcotics. Based on this, the problem that will be discussed is how the monodualistic principle in eradicating criminal acts of narcotics abuse committed by children is contrary to the law related to Law No. 35 of 2009 and Law No. 11 of 2012. This research is normative juridical research, namely research conducted by examining library materials or secondary data. In terms of implementing the diversion, there are several things that make it impossible. There are several factors that cause the diversion of children who abuse narcotics to not be achieved,namely internal and external factors. @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;}

Abstract

This research aims to analyze judicial discretion in sentencing perpetrators of aggravated assault resulting in serious bodily injury. The research method employed is normative legal research with a statute approach and a case study approach, which is analyzed qualitatively through content analysis. The results show that the defendant was charged alternatively with a primary indictment of attempted murder, a subsidiary indictment of aggravated assault resulting in serious bodily injury, and a lesser subsidiary indictment of simple assault. The charges by the Public Prosecutor were in line with the subsidiary indictment of aggravated assault resulting in serious bodily injury as supported by the Visum et Repertum. Conversely, the judge’s verdict, based on the lesser subsidiary indictment of simple assault, emphasizes judicial discretion. Judicial discretion is an effort to balance the enforcement of positive law and the achievement of substantive justice by considering the values that live in society (living law). The decision reflects the struggle between formal legality and contextual substantive justice. Therefore, more precise guidelines are needed regarding the limits and parameters of judicial discretion, especially in cases that intersect with living law. Improving the quality of the Visum et Repertum and strengthening judges’ capacity to understand living law are also important to strive for in order to achieve a responsive and just judicial system.
