Abstract

Keterampilan proses sains merupakan salah satu dari capaian pembelajaran pada kurikulum merdeka pada pembelajaran IPA. Penelitian ini menggunakan literatur review pada sejumlah artikel yang telah diterbitkan pada jurnal pendidikan IPA di Indonesia setelah pandemi covid-19 tahun 2021-2024 dengan keterampilan proses sains pada pembelajaran IPA di SMP sebagai fokus penelitian. Artikel yang dikumpulkan melalui database google scholar dan dipublikasikan melalui jurnal terakreditasi Kemendikbudristek. Terdapat 17 data jurnal yang menjadi sampel. Teknik analisis data yang digunakan adalah teknik PRISMA. Berdasarkan hasil analisis penelitian diperoleh bahwa terdapat beberapa model pembelajaran yang dapat melatihkan keterampilan proses sains dengan baik dan membantu peserta didik dapat menyelesaikan masalah sehari-hari.Kata kunci: keterampilan proses sains, literatur review, teknik PRISMA, pembelajaran IPA.

Abstract

This study aims to build and analyze the SELR mathematical model in the context of the Independent Curriculum, in order to explore and predict the gap in student achievement between urban and remote areas in South Sulawesi. This study combines theoretical studies and applications by conducting simulations using Maple software. The study population involved 400 students from urban areas and 400 students from remote areas where simulation data was used to predict the dynamics of adaptation to the Independent Curriculum. The results showed that the Independent Curriculum was not fully effective in addressing the achievement gap, with a low basic reproduction number (R₀), both in urban and remote areas. The R₀ value of 0.204 in urban areas and 0.614 in remote areas indicates that the spread of curriculum adaptation is still limited and cannot create a significant impact on improving student achievement. This study indicates the need for additional adjustments and interventions in the implementation of the Independent Curriculum to achieve more equitable and inclusive results in various regions .

Abstract

ABSTRACTTuberculosis or TBC is a type of chronic infectious disease caused by bacteria called Mycobacterium tuberculosis. The disease poses a serious threat to health regardless of age or gender. Individuals infected with this disease will experience symptoms such as coughing with sputum or blood, chest pain, and high fever. Transmission occurs through aerosols and droplets, allowing the bacteria to spread through the air and requires a minimum of 6 months of treatment for recovery. Therefore, The SITR (Suspectible-Infective-Treatment-Recovered) mathematical model with the Euler method is appropriately used in this article to describe the condition where infected individuals need treatment for recovery. The data analyzed comes from tuberculosis case reports collected by the South Sulawesi Regional Health Agency in 2015. This research has important relevance in understanding the dynamics of TB spread and provides a basis for the development of disease spread strategies. By using mathematical models, key factors affecting the spread of tuberculosis can be identified. Keywords: Mathematical Model, SITR Model, Dynamics of Spread, Tuberculosis.

Abstract

This research aims to reveal the potential of Rat Island as a marine ecotourism destination as well as a contextualized physics learning environment. Using the descriptive qualitative method and literature review support, data were obtained through field observations and literature analysis related to sediment topography, climate, and physics concepts such as ocean waves and tree height measurements. Previous research stated that Rat Island has marine ecotourism potential that can be used as contextual physics learning material. Observation activities in the natural laboratory of Rat Island by Master of Science Education students succeeded in increasing the enthusiasm for learning and inquiry skills. Physics analysis related to tree height measurement provides a deep understanding of physics concepts that can be applied in everyday life. In addition, the research showed the tidal pattern on Rat Island as a periodic physical phenomenon that can be studied and predicted. The concept of Rat Island as a natural laboratory supports its potential as a place for learning and experimentation while supporting environmental conservation efforts. Overall, Rat Island has great potential as a source of contextual physics learning and a sustainable marine ecotourism destination.Keywords: Rat Island, Physics Learning, Tidal Wave, Natural Laboratory.

Abstract

Pegagan atau yang dikenal dengan nama Pegagan merupakan tanaman perdu yang mengandung zat gizi dan senyawa aktif yang baik bagi tubuh, karena memiliki khasiat sebagai antibakteri, antivirus, antihipertensi, diuretik dan antiinflamasi. Tanaman ini merupakan sumber senyawa fenolik, flavonoid, triterpenoid, alkaloid dan tanin. Penelitian ini bertujuan untuk mengevaluasi aktivitas antibakteri daun pegagan. Daun pegagan diekstraksi dengan pelarut etanol 70%, kemudian difraksinasi dengan pelarut n-heksana, etil asetat dan metanol. Evaluasi aktivitas antibakteri menggunakan metode difusi cakram pada konsentrasi 5%, 10% dan 15% terhadap Escherichia coli dan Staphylococcus aureus dengan mengukur zona bening yang terbentuk di sekitar kertas cakram. Hasil penelitian menunjukkan bahwa ekstrak etanol 70%, fraksi etil asetat dan fraksi metanol:air memiliki aktivitas antibakteri terhadap kedua bakteri tersebut, sedangkan fraksi n-heksana tidak memiliki aktivitas antibakteri terhadap kedua bakteri tersebut. Ekstrak etanol dengan konsentrasi 5% menunjukkan aktivitas paling efektif dalam menghambat Escherichia coli dengan zona hambat 13,67 ± 0,428 mm dan fraksi metanol:air dengan konsentrasi 5% terhadap Staphylococcus aureus dengan zona hambat 9,35 ± 0,17 mm.Kata kunci: Antibakteri, Centella asiatica, Escherichia coli, Staphylococcus aureus
