This research is an experimental research with Mastery Learning model. This study aims to determine the effect of the Mastery Learning model on student learning outcomes on the mole concept material. This research was conducted in class X SMA Negeri 1 Remboken with a sample of 57 people. The research design used is the post-test-only control group design experimental method. The experimental class uses a complete learning model and the control class uses a conventional learning model. Analysis of hypothesis testing using t-test with a significant level = 0.05, because with a two-way test then the value of a/2 = 0.025. The test results obtained show that the results of t arithmetic > t table or 9.02 > 2.05, thus H0 is rejected and H1 is accepted, this indicates that there is a significant difference between the average value (post-test) of the experimental group and the experimental group. control group experiment. So it can be concluded that there is a difference in the average learning outcomes of students who are taught the mastery learning model with the learning outcomes of students who are taught conventional learning on the mole concept material.

This research is an experimental study using the Anchored Instruction learning model. This study aims to determine the effect of the Anchored Instruction learning model on student learning outcomes on the mole concept subject. This research was conducted in class X SMA Negeri 2 Siau Timur with a sample of 40 people. The research design used was a pre-test and randomized two group design. The experimental class uses the Anchored Instruction learning model and the control class uses the conventional learning model. Analysis of the hypothesis test using t-test with a significant level α = 0.05. The test results obtained indicate that the results of tcount> ttable or 2.112> 2.024, thus H0 is rejected and H1 is accepted, this shows that there is a significant difference between the average value of the initial test (posttest) of the experimental group and the control group. So it can be concluded that there is a difference between student learning outcomes using the Anchored Instruction learning model and student learning outcomes using conventional learning models on mole concept subject.

Suseptibilitas Magnetik dan Konsentrasi Logam Berat Sedimen Sungai Tallo di Makassar Vistarani Arini Tiwow; Meytij Jeanne Rampe; Sulistiawaty Sulistiawaty

Publisher : Sam Ratulangi University

Keberadaan Sungai Tallo sangat penting bagi industri dan masyarakat yang berada di daerah aliran sungai. Namun, aktivitas sosial-ekonomi tidak dibarengi dengan pengelolaan sampah yang bertanggung jawab. Dengan demikian, secara umum sungai tercemar oleh polutan seperti logam berat. Oleh karena itu, perlu dilakukan monitoring sebagai langkah pengendalian kualitas Sungai Tallo untuk menghindari kondisi yang semakin buruk. Tujuan penelitian ini yaitu untuk meningkatkan pemahaman tentang hubungan antara parameter magnetik dan kandungan logam berat pada sedimen Sungai Tallo. Metode yang digunakan adalah metode magnetik lingkungan menggunakan parameter suseptibilitas magnetik. Selanjutnya, dilakukan pengujian X-Ray Fluorescence (XRF) untuk mengetahui konsentrasi unsur logam berat. Hasil menunjukkan Suseptibilitas magnetic sedimen Sungai Tallo berkisar 47,7 sampai 968,7 Ã— 10-8 m3/kg. Suseptibilitas magnetik berhasil mengidentifikasi kelimpahan logam berat pada Sungai Tallo. Fe memiliki konsentrasi yang lebih tinggi dibandingkan Cr, Mn, dan Zn. Korelasi antara unsur logam berat Fe, Mn, dan Zn dengan suseptibilitas magnetik diperoleh korelasi positif kuat dimana unsur logam berat berkontribusi terhadap suseptibilitas magnetik. Studi ini mendukung parameter magnetic seperti suseptibilitas magnetik dapat berpotensial digunakan sebagai indikator polusi logam berat pada Sungai Tallo.Kata kunci: Logam berat; magnetik lingkungan; suseptibilitas magnetikMagnetic Susceptibility and Heavy Metal Concentration of Tallo River Sediments in MakassarABSTRACTThe existence of the Tallo River is very important for industry and people living in the watershed. However, socio-economic activities are not accompanied by responsible waste management. Thus, rivers are generally polluted by pollutants such as heavy metals. Therefore, monitoring is necessary as a measure to control the quality of the Tallo River to avoid worsening conditions. The purpose of this study was to improve understanding of the relationship between magnetic parameters and heavy metal content in Tallo River sediments. The method used was the environmental magnetic method using magnetic susceptibility parameters. Furthermore, X-Ray Fluorescence (XRF) was tested to determine the concentration of heavy metal elements. The results showed that the magnetic susceptibility of the Tallo River sediments ranged from 47.7 to 968.7 Ã— 10-8 m3/kg. Magnetic susceptibility identified the abundance of heavy metals in the Tallo River. Fe has a higher concentration than Cr, Mn, and Zn. The correlation between heavy metal elements Fe, Mn, and Zn with magnetic susceptibility showed a strong positive correlation where heavy metal elements contribute to magnetic susceptibility. This study supports magnetic parameters such as magnetic susceptibility that can potentially be used as an indicator of heavy metal pollution in the Tallo River.Keywords: Environmental magnetic; heavy metal; magnetic susceptibility

Studi Suseptibilitas Magnetik Bergantung Frekuensi pada Sedimen Sungai Tallo, Kota Makassar, Indonesia Vistarani Arini Tiwow; Meytij Jeanne Rampe
Jurnal Fisika Unand Vol 11 No 4 (2022)
Publisher : Universitas Andalas

Telah dilakukan studi tentang pengukuran suseptibilitas magnetik bergantung frekuensi pada sedimen Sungai Tallo di Kota Makassar. Metode yang digunakan adalah metode suseptibilitas magnetik menggunakan alat Bartington Susceptibility Meter MS2B. Hasil menunjukkan bahwa suseptibilitas magnetik pada frekuensi rendah dan tinggi terdapat perbedaan yang tidak signifikan yang berarti sampel sedimen hampir tidak memiliki bulir mineral superparamagnetik. Korelasi antara suseptibilitas magnetik bergantung frekuensi dan suseptibilitas magnetik pada frekuensi rendah memiliki korelasi positif yang kuat. Peningkatan Ï‡LF menyebabkan Ï‡FD juga meningkat. Sampel sedimen mengandung butir multi domain (MD) dan superparamagnetik-simple single domain (SP-SSD). Kelimpahan mineral magnetik dipengaruhi oleh adanya aktivitas antropogenik di sekitar sungai.
