Abstract

The purpose of this study was to find the effects of GeoGebra- assisted Missouri Mathematics Project (MMP) learning model on students’ mathematical communication abilities. The study can be categorized as a quantitative experimental research type with a quasy-experimental design. The research population refers to all grade X Physics students of private Senior High School in South Tangerang. The purposive sampling technique was used to a sample size of 38 students as the experiment group and  another 34 students as the control group. Data were collected using a descriptive test of mathematical communication ability on the material of the three-variable linear equation system. Further, the t-test was used to analyze the data. Findings showed that the GeoGebra-assisted MMP learning model improves the students mathematical communication abilities at the moderate category.

Abstract

Salah satu inovasi model pembelajaran pada penelitian sebelumnya memperlihatkan adanya hubungan yang erat terkait Problems based Learing dengan kemampuan berpikir kritis matematis. Problem Based Learning (PBL) atau dalam bahasa Indonesia yaitu Pembelajaran Berbasis Masalah  merupakan inovasi dalam pembelajaran karena dalam Pembelajaran Berbasis Masalah (PBM) kemampuan berpikir siswa betul-betul dioptimalisasikan melalui proses kerja kelompok atau tim yang sistematis, sehingga siswa dapat memberdayakan, mengasah, menguji dan mengembangkan kemampuan berpikirnya secara berkesinambungan. Penelitian ini dikembangkan melalui analisis bibliometrik data yang diekstraksi dari database Google scholar dengan pengumpulan data menggunakan media Publish or Perish (PoP) dan visualisai data menggunakan VOSviewer. Metadata untuk 300  artikel  model pembelajaran Problem Based Learning pada kemampuan berpikir kritis matematis siswa yang diekstrak dari database Google Cendekia menggunakan perangkat lunak Publish or Perish (PoP). Artikel ini diterbitkan hingga 2022. Kemudian kami menggunakan perangkat lunak VOSviewer untuk melakukan visualisasi jaringan, overlay, dan kepadatan. Hasil yang di dapat berdasarkan data yang terkumpul menyatakan bahwa masih sangat besar kemungkinan untuk memperdalam penelitian terkait Problem Based Learning dan kemampuan berpikir kritis matematis siswa.

Abstract

Perkembangan pesat dibidang informatika telah membawa dampak signifikan pada berbagai aspek kehidupan manusia. Ini disebabkan oleh kemajuan teknologi komputer, perangkat mobile, jaringan internet, dan berbagai aplikasi perangkat lunak yang terus berkembang. Prediksi harga rumah menjadi suatu hal yang krusial karena dapat membantu calon pembeli, penjual, dan pihak terkait lainnya untuk membuat keputusan yang informasional dan cerdas. Tujuan penelitian ini yaitu untuk mengetahui faktor yang paling berpengaruh terhadap harga rumah, mengetahui perbandingan tingkat akurasi dari kedua algoritma dalam prediksi harga ruumah, dan cara generalisasi model regresi linier ke pasar perumahan yang berbeda. Metode yang digunakan dalam prediksi harga rumah adalah metode KDD menggunakan algoritma regresi linear dan k-nearest neighbor dalam konteks data mining. Pada penelitian ini faktor yang paling berpengaruh terhadap harga rumah adalah luas bangunan dengan nilai koefisien sebesar 23047431.201. Algoritma KNN mempunyai hasil akurasi yang lebih baik dibandingkan dengan regresi linier, perbandingan tingkat akurasi ini diambil berdasarkan nilai relative error. Hasil nilai relative error regresi linier sebesar 71.95% +/- 82.63%. Sedangkan hasil relative error k-nearest neighbor pada gambar sebesar 30.95% +/- 29.87%. Model regresi linier dapat digeneralisasi dengan baik ke pasar perumahan yang berbeda melibatkan beberapa pendekatan. Diantaranya yaitu Pengumpulan data yang representatif, normalisasi dan standarisasi, pemahaman konteks pasar.

Abstract

The culture of Nusantara represents a wealth that reflects the diversity of ethnicities, traditions, and local values in Indonesia. From the perspective of Islamic law implementation, the interaction between local culture and Sharia norms is highly relevant. Islamic law, which is universal in nature, needs to be integrated with local cultures to ensure its acceptance and understanding by the community. This study employs a literature review method to analyze various primary and secondary sources, including Islamic legal texts, scholarly works, historical documents, and literature on Nusantara culture. It examines how the values of Nusantara culture, such as deliberation (musyawarah), mutual cooperation (gotong royong), and local wisdom, can strengthen the application of Islamic law within the social and cultural contexts of society. Through this approach, the study aims to highlight the importance of dialogue between Islamic law and local culture and its implications for fostering a harmonious and just society. The findings are expected to provide insights into the synergy between law and culture in creating a more effective and inclusive legal system in Indonesia.

Abstract

Antibacterial secondary metabolites such as tannins and their derivatives are found in the Vernonia amygdalina Del. Antibiotic resistance can develop due to overuse, reducing the efficacy of drugs to prevent and treat infections. This research aims to use the Quantitative Structure-Activity Relationship (QSAR) and the semi-empirical method Austin Model 1 (AM1) to design a modified novel compound from African leaves that has improved antibacterial activity. This research includes a descriptor calculation of QSAR using AM1 MOE on typical compounds from African leaves, and calculation results are chosen based on a multilinear regression statistical analysis. The model equation represents the three primary parameters of QSAR, which are electronic, hydrophobic, and steric parameters, which will be used to measure modified compounds. Molecular docking using Autodock Tools (The Scripps Research Institute, USA), and analysis of results of docking Autodock Tools using Discovery Studio 3.5 Client. The best QSAR model obtained is LogEC50 = (0.829 x LogP) - (1,302 x AM1_HOMO) - (0.339 x AM1_dipole) - (5,128 x mr) + (0.145 x vol) - (11,355). The results showed that EC50 prediction of modified hamamelitannin has the best activity with the lowest ΔGbind -9.0 kcal/mol and inhibition constant of 0.249 μM. In summary, the novel compound's design calculation has better antibacterial activity, as indicated by a lower EC50, than fosfomycin or compounds without modification. The modified hamamelitannin compound was found to have better antibacterial activity (prediction EC50 = 0.1933 μM) than the original (experimental EC50 = 145.50 μM).
