Abstract

This study aims to determine the inhibitory activity of ethanol extract from tamarind seeds against the growth of Escherichia coli and Staphylococcus aureus bacteria at various concentrations. This study used a randomized complete block design with 1 factor, namely the concentration of tamarind seed extract with 6 levels, namely A1 (0.5%), A2 (1%), A3 (1.5%), A4 (2%), A5 (2.5%), A6 (3%). Each treatment was repeated 3 times. Research evaluation includes qualitative phytochemical tests and antioxidant activity against ethanol extract of gelugur acid seeds and bacterial inhibition. The results showed that in the ethanol extract of tamarind seeds there are phytochemical compounds which include flavonoids, saponins, tannins, and terpenoids. And has antioxidant activity of IC 50 = 15.77 ppm. Tamarind seed extract affects the growth of Escherichia coli and Staphylococcus aureus bacteria. The minimum concentration of ethanol extract of tamarind seeds that can inhibit Escherichia coli and Staphylococcus aureus bacteria is 0.5% with inhibitory zones of 15.6 mm and 10.9 mm respectively.

Abstract

The environment is defined as a set of aspects in the form of physical, chemical and biological as well as social factors that have a direct or indirect relationship to living things and human activities in the short and long term. However, the environment can experience various problems, one example is environmental damage by causing waste in the environment. One of the reasons for the waste generated by the community is their lack of knowledge about the environment. It was proven in preliminary research at SMA Negeri 11 Pinrang, the results of the initial analysis using students' environmental knowledge questions were still low with an overall result of 43.73. These results indicate that there are still many students who do not know environmental topics and problems, especially waste and its processing, so they are lazy about disposing of waste according to the server and processing the waste, especially wet waste. This research is development research referring to Plomp and Nieven's development design and conducting a quasi-experiment using the PjBL model in class X at SMA Negeri 11 Pinrang. The research results show that the printed module has a practicality value of 91.1% in the very practical category so it is suitable for use in the learning process. The average pretest result for the experimental class was 50.8 in the low category after learning using printed modules and the PjBL model and the posttest was 88 in the very high category and experienced an increase of 37.2%. The average pretest result for the control class was 44.26 in the low category after learning only using the PjBL model and the posttest was 79.6 in the high category and experienced an increase of 35.34%. Therefore, it can be concluded that the printed module is practical and effective in the experimental class with an N-Gain value of 0.75.

Abstract

Kegiatan praktikum biologi materi mobilitas pada manusia kelas XI SMA/MA siswa menggunakan buku teks biologi yang disediakan di perpustakaan, dan lembar kerja yang ditulis oleh guru pada kertas double folio sebagai pedoman kegiatan. Ketersediaan buku biologi di perpustakaan tidak begitu mencukupi sehingga tidak semua siswa mampu memanfaatkan buku tersebut dengan baik. Penelitian ini bertujuan untuk mengembangkan pentunjuk praktikum materi mobilitas pada manusia kelas XI SMA/MA dengan pendekatan inkuiri bebas dimodifikasi yang valid, layak, dan efektif. Studi ini merupakan penelitain pengembangan dengan model Plomp yang terdiri dari tiga tahapan pengembangan yaitu, tahapan pendahuluan (preliminary research phase), tahapan prototip (prototyping phase), dan tahapan penilaian (assesment phase). Instrumen penelitian yang digunakan untuk memperoleh data kevalidan dan kelayakan adalah angket dengan Skala likert. Uji efektifitas sikap siswa dinilai dengan lembar penilaian observasi sikap, dan uji efektifitas keterampilan dengan penilaian laporan praktikum. Analisis data dilakukan secara deskriptif. Hasil penilaian menunjukkan bahwa penuntun praktikum sangat valid (92.25%), sangat layak (91.10%) pada one to one, sangat layak (91.5%) pada small group, sangat mudah (97.88%) oleh guru, dan sangat mudah (83.53%) oleh peserta didik. Hasil uji lapangan diperoleh bahwa penuntun praktikum pada aspek sikap sangat efektif (97.06%) dan aspek keterampilan sangat efektif (85.46%).

Abstract

The ELISA (Enzyme Linked Immunoassay) method has high sensitivity and specificity, qualitatively and quantitatively detecting Hepatitis B Surface Antigen (HBsAg) levels, but the process is long, expensive and requires special expertise, compared to the Rapid Diagnostic Test (RDT) as a rapid test which is more practical and cheaper. The aim of this study was to compare the sensitivity and specificity of the Entebe Rapid Test Diagnostic (ERTD) produced by PT. Hepatika Mataram, with ELISA as the gold standard in detecting HBsAg. The requirement for interpreting sensitivity and specificity results according to World Health Organization (WHO) standards is a minimum of 95%. Testing with a negative panel of 00 samples and a positive panel of 1 samples from Papua in 012 at -80℃ storage. Testing in April 023 at the Molecular Diagnostics and Research Laboratory, Mataram University Hospital. Statistical analysis using MedCal software. ERD HBsAg produced by PT. Hepatika Mataram has a sensitivity of 95.45%, specificity of 99.50%, positive predictive value of 93.59%, negative predictive value of 99.65%, and accuracy of 99.21%.

Abstract

Students who are prospective teachers must adapt to the development of digital technology, especially its use in education. They are taught teaching practices with their peers before going directly into the field, as well as how to create learning tools. This research aims to analyze the ability of prospective teachers to develop student worksheets (LKPD) that foster 21st-century skills. This study is a qualitative descriptive research involving 14 student teachers as subjects. Data collection was conducted using assessment sheets. The results of the study indicate that (1) the LKPD created by the prospective teachers had an average score of 3.28, categorized as high; (2) the critical thinking aspect had an average score of 3.32, categorized as high; communication had an average score of 3.41, categorized as high; collaboration had an average score of 3.45, categorized as high; and creativity and innovation had an average score of 2.95, categorized as moderate. This shows that the prospective teachers are quite proficient in developing LKPD that build 21st-century skills.
