Abstract

Penelitian ini bertujuan untuk menguji ada atau tidaknya pengaruh antara pemahaman konsep matematika siswa yang belajar menggunakan metode pembelajaran Syndicate Group dengan siswa yang belajar menggunakan pembelajaran konvensional. Penelitian ini adalah penelitian Quasi Eksperimentdengan desain Pretest Posttest Control Group Design. Sampel pada penelitian ini adalah siswa kelas X SMA Negeri 14 Pekanbaru. Pengumpulan data dalam penelitian ini menggunakan dokumentasi, observasi dan tes. Untuk mengetahui hasil penelitian mengenai pemahaman konsep matematika siswa dilakukan uji t. Pengambilan keputusan dilakukan dengan membandingkan nilai t hitung dengan ttabel baik dengan taraf signifikan 5% maupun 1% yaitu 2,00 dan 2,65 dimana nilai thitung adalah 6,09. karena thitung > ttabel, sehingga Ho ditolak dan Ha di terima. Berdasarkan hasil analisis data tersebut, diambil kesimpulan bahwa terdapat perbedaan antara pemahaman konsep matematika siswa yang belajar menggunakan metode pembelajaran Syndicate Group dengan siswa yang belajar menggunakan pembelajaran konvensional. Artinya, terdapat pengaruh metode pembelajaran SyndicateGroup terhadap pemahaman konsep matematika Siswa SMA Negeri 14 Pekanbaru.

Abstract

Accuracy measurements were carried out on a table movement of four axis machining center using laser interferometer based integrated measuring system. In this case the measurements included table positioning accuracy in x-axis direction and table angular as well as table straightness displacement accuracy. Following the obtained results, analysis of the machining center table displacement was carried out by modeling the table accuracy movement using a homogenous transformation matrix (HTM) method. Guide ways deflection was analyzed using five contact point method and other analysis performed by taking into account misalignment between ball screw & slideways. Diagnosis was conducted by comparing the theoretical table accuracy displacement curve and the one obtained from laser interferometer based measurement, for determining the slideways wear contour and the progressive wear of the ball screw.

Abstract

In the modern legal system, Deoxyribonucleic Acid (DNA) testing has become an important tool in the resolution of criminal and civil cases in Indonesia. The use of DNA can assist in determining blood relations, uncovering sexual abuse cases, and proving involvement in other crimes. Nonetheless, there are various legal issues that arise regarding the collection of DNA specimens without the consent of the sample owner. In Indonesia, although there are personal data protection regulations such as the Health and Population Administration Law, there are no specific provisions regarding the legality of unauthorized DNA sampling. This creates uncertainty in the legal system, especially in terms of evidence being recognized in court. Unauthorized DNA sampling can violate an individual's right to privacy guaranteed by the 1945 Constitution and the Criminal Procedure Law. This potentially makes DNA test results inadmissible as valid evidence in court. Therefore, this study aims to analyze the legality of the practice of unauthorized DNA sampling and its impact on the legal evidentiary system in Indonesia. The study also highlights the importance of medical ethics and legal protection of privacy in determining the validity of DNA evidence in judicial proceedings. It also explores the role of medical ethics and privacy law in determining the validity of DNA test results in the judicial process, and provides recommendations for clearer regulations regarding DNA sampling procedures.
