This study aims to describe the profile of students' metacognitive skills in solving integral calculus problems seen from the aspects of planning, monitoring and evaluation metacognitive skills. The research method used is descriptive qualitative research methods. The subjects in this study were 3rd semester students who had taken courses or were taking calculus II courses for the 2020/2021 academic year which were carried out using purposive sampling technique. In this study, the instrument used was a test to measure the ability in solving integral calculus problems in the form of essay questions, unstructured interview guidelines, documentation and observation. Data were analyzed in three stages, namely reduction, presentation, and conclusion or verification. The results in this study were students with high problem solving abilities had met the indicators of metacognitive skills, namely the planning, monitoring and evaluation stages. Students with moderate problem-solving abilities have only reached indicators of metacognitive skills, namely the planning and monitoring stages, but have not reached the evaluation stage, while students with low problem-solving abilities have not measured metacognitive skills indicators both at the planning, monitoring and evaluation stages. So that students with high problem solving abilities are more likely to have good metacognitive skills, because students with high problem solving abilities are well organized from planning, monitoring to the evaluation stage.

Smartphones are a physical learning medium that can support students to experiment with measurement devices. One of the smartphone apps that can be used is phyphox. The study aims to find out collision analysis lends several types of fall fields that include soil, ceramic floor areas and board fields so that it will generate data on the height, time, and energy generated when objects hit the surface. The method used is an experiment with a collision testing comparison approach with different drop fields using phyphox and stopwatch applications. The results of three experiments in the energy board field that apples produce are larger than ceramic and soil floor fields. While the results of experiments using stopwatches showed that the energy produced has a slightly greater value than using phyphox. Phyphox application can be used for practicum independently.

The presence of arboreal insects in residential areas became indicator that the area is still overgrown with vegetation, whether flowering or not. The existence of vegetation in residential areas is referred to as Ruang Terbuka Hijau (RTH). The types of arboreal insects in Kelurahan Sungai Pinang Dalam Kota Samarinda have never been reported. This study aims to determine the role of the diversity of arboreal insect species in residential areas in Kelurahan Sungai Pinang Kota Samarinda. The sampling method for arboreal insects is a direct collection method using a sweeping net with a residential transect method for a month, once every two days in the morning and evening. The steps carried out in this study were collecting samples of arboreal insects, identifying and analyzing data on the index values of diversity, richness, evenness and dominance. The results showed that 26 genera of arboreal insects were found which were classified into 18 families and 8 orders. The diversity index value (H') of arboreal insect species in the morning is 2.7601 and in the afternoon is 2.4901. The dominance index value (C) obtained in the morning is 0.0880 and in the afternoon is 0.1192. For the evenness value, obtained in the morning of 0.8471 and in the afternoon of 0.8056. For the value of the wealth index (R), which was obtained in the morning was 4.1373 and in the afternoon was 3.6711.

This research is based on the results of the evaluation of the last ten years related to the development of studies in the Mathematics Education Master Program, Tanjungpura University, through a partnership model to develop and implement national and international comparative studies on mathematics teacher education. The aims are to describe the methodology used in the national level study of teacher education through the Teacher Professional Education Program or Pendidikan Profesi Guru (PPG)- Teacher Education and Development of Studies in Mathematics and share key findings related to mathematics preparation for future teachers. The research applied a quantitative approach with cross-sectional survey method with students of the master program of mathematics education class of 2019/2022 and 2020/2021. The results of the study show that future teacher performance: (1) has less opportunity to learn than high achievers in geometry, functions, calculus, and groups with mastery of linear algebra, number theory, analytic geometry, introduction to probability, and statistics and (2) has less opportunity for those who study school mathematics in data representation, calculus compared to linear algebra, analytic geometry, introduction to calculus, calculus, probability, and statistics. Thus, it can be concluded that attention and emphasis are needed on the type and depth of learning materials given to future teachers who continue their studies at the master's level. This pattern represents an extension to better future secondary school teachers.

The excessive use of antibiotics in the treatment of infections or diseases caused by Staphylococcus aureus is the main cause of antibiotic resistance. Methicillin-resistant S. aureus (MRSA) strains are a serious problem because of their wide distribution in the clinical environment and the living community, so it is necessary to search for antibacterial sources from natural products and traditional medicines such as Kayu racun leaves (Rhinacanthus nasutus). Information regarding the content of the active ingredient and the antibacterial potential of the ethanol extract of Kayu racun leaves is still limited. This study aims to test the phytochemical and antibacterial activity of the ethanol extract of Kayu racun leaves against S. aureus and MRSA bacteria by invitro. The research used an experimental method and was divided into two stages, namely; Phytochemical test of the ethanol extract of Kayu racun leaves using the Thin Layer Chromatography (TLC) method and the antibacterial activity test of the ethanol extract of Kayu racun leaves against S. aureus and MRSA using the paper disc diffusion method. Based on the research results, it can be concluded that the ethanol extract of Kayu racun leaves contains alkaloids, phenols, and flavonoids. The best antibacterial activity was found at a concentration of 100 mg/ml with an inhibition zone diameter of 26.20 mm against S. aureus and 17.90 mm against MRSA.
