Abstract

Penelitian ini mengkaji pengaruh penggunaan radiasi gamma di bidang kesehatan, salah satunya adalah penggunaan sinar gamma dalam proses radioterapi. Penyerapan energi radiasi ke dalam tubuh dapat menyebabkan munculnya radikal bebas dalam tubuh yang dapat merugikan organ lain di sekitar target penyinaran. Penelitian ini bertujuan untuk mengetahui pengaruh paparan radiasi gamma terhadap hepar mencit dan sifat hepatoprotektif ekstrak kulit manggis(Garcinia mangostana) dalam mengurangi kerusakan sel yang ditimbulkan. Penelitian ini dilakukan dengan memberikan ekstrak kulit manggis 5 dosis varian berbeda ke mencit dan diberi paparan radiasi selama 40 menit dengan dosis total 268 μSv selama 14 hari, kemudian diukur kadar SGPT (serum glutamic pyruvic transaminase) dan jumlah kerusakan sel dari preparathistopatologis. Hasil penelitian menunjukkan kadar SGPT turun menjadi 77,7 U/L dari kadar awal 128,67 U/L. Hal ini membuktikan bahwa ekstrak kulit manggis memiliki sifat hepatoprotektif yang dapat mengurangi kerusakan sel akibat paparan radiasi gamma.

Abstract

This study aims to develop a two-level Natural Science (IPA) test instrument based on the jumanji game in measuring understanding of the concept of work and simple planes. The research method in this case is a quantitative method with a modification of the development model. The measurement instrument developed in this study is a two-level science test or a reasoned multiple choice test specifically for the business chapter and simple planes. This research instrument that has been developed was tested on 256 students of SMP Abu Bakar. The results of this study indicate that a measurement instrument has been produced in the form of a two-level science test based on the jumanji game which can measure students' understanding of concepts about business and simple and reliable machines that are valid and reliable. These results are evidenced by the validity and reliability of the two-level science test, which are 0.83 and 0.53 respectively. Meanwhile, the achievement of students' understanding of concepts related to business and simple machines is 51% which is in the high category. The students' conceptual understanding measured using the two-level science test is high because it exceeds the minimum criteria that have been determined.

Abstract

This study aims to describe the effectiveness of the use of a spring oscillator practicum on students of SMA Negeri 1 Indramayu and SMA Negeri 2 Indramayu. The method used is the ADDIE model R & D method using a one group pretest-posttest design. The results showed that the calculation of the n-gain score of 0.688 and 0.680 obtained the interpretation of increasing student learning outcomes in the medium category. Meanwhile, students' responses to the spring oscillator practicum tool obtained an average score of 82.3% from the three aspects with the interpretation of the score "good". From the research data, it can be concluded that the use of a spring oscillator is effective in high school physics learning

Abstract

Kegiatan pembelajaran atau belajar mengajar yang optimal sangat membutuhkan lingkungan yang kondusif, dan tenang karena dibutuhkan konsentrasi yang cukup tinggi pada prosesnya. Kawasan lingkungan kampus memerlukan lingkungan yang tenang dan tidak bising. Tujuan penelitian ini adalah untuk mengetahui tingkat kebisingan di lingkungan Universitas San Pedro. Pengukuran tingkat kebisingan dilakukan dalam tiga hari penelitian dengan pengambilan data 2 jam perhari. Data penelitian terdiri atas data primer dan data sekunder. Data primer adalah data yang diperoleh secara langsung dengan menggunakan alat SLM (sound level meter). Data sekunder yang digunakan dalam penelitian ini adalah dapat menghitung banyaknya kendaraan yang melintas sekitaran kampus Universitas San Pedro. Dari hasil penelitian Tingkat kebisingan diarea gedung Universitas San Pedro belum sesuai dengan standar baku yang telah ditetapkan yaitu masih lebih besar dari 55 dB (A), sehingga perlu dilakukan penanganan untuk mengurangi kebisingan yang diterima

Abstract

The implementation of technology-based learning is currently increasingly developing, so teachers need to increase their competence in developing learning media. This community service activity is carried out through training methods. This training activity aims to increase teacher competency in learning through microlearning training with Google Sites. The target of this activity is the MA Al Ikhlas Berbah teacher. This microlearning training with Google sites was attended by 17 MA Al Ikhlas Berbah teachers and was carried out from June to July 2023 with 5 stages of activities including 1) surveys and permits in the form of observing learning needs and implementation; 2) socialization includes explanation of planned training activities; 3) training related to the explanation and practice of microlearning with Google sites; 4) monitoring and assisting in the creation of microlearning-based learning media using Google Sites and 5) evaluating the implementation of training. The results of this service in the form of training activities are increasing the competency of MA Al Ikhlas Berbah teachers through microlearning training with Google sites which can be seen from the pretest and posttest results which have increased to 97.75% in understanding the implementation of microlearning in learning.
