Abstract

A B S T R A C TThis study aims to determine the effect of the Multiple Intelligence model on chemistry learning outcomes student in colloidal system material. This research was conducted from May to June for the 2021/2022 school year, students of class XI IPA at SMA Negeri 2 Tondano. The sampling technique was carried out using random sampling. The samples used in this study were 22 students of class XI IPA 1 as the experimental class and 22 students in class XI IPA 2 as the control class. The research design used was the Pretest-Postest Control Group Design. Research data on learning outcomes were measured after treatment in the experimental and control classes, then data analysis was carried out using Analysis of Covariance (ANCOVA) to test the formulation of hypotheses with the testing criteria, namely reject Ho if Fcount>Ftable. The research results obtained for learning outcomes are Fcount>Ftable, at the real level α=0.05 and db=42, namely Fcount= 36.378>Ftable=1.671, so Ho is rejected and H1 is accepted. Based on the data analysis, it can be concluded that the use of the Multiple Intelligence model has an effect on chemistry learning outcomes student’s.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui efektivitas tes diagnosis multiple intelligence terhadap hasil belajar siswa pada materi ikatan kimia di SMA Negeri 1 Tondano. Penelitian ini dilakukan pada tahun ajaran 2022. Metode yang digunakan adalah eksperimen dengan desain one-group pretest posttest design. Teknik pengumpulan data diperoleh melalui instrumen tes hasil belajar sebanyak 36 butir soal pilihan berganda yang kemudian dianalisis menggunakan uji N-gain. Hasil penelitian menunjukkan bahwa nilai rata-rata N-gain untuk kelas eksperimen adalah sebesar 67% termasuk dalam kategori cukup efektif. Hasil perhitungan menunjukkan bahwa, rata-rata skor hasil belajar siswa untuk kelas eksperimen pretest 54.9483 dan posttest 85.3989. hasil pengujian paired sample t-test hasil belajar siswa diperoleh nilai signifikannya yaitu 0,000 < 0,05 maka H0 ditolak atau H1 diterima Ini menunjukkan bahwa pembelajaran multiple Intelligence efektif untuk meningkatkan hasil belajar siswa.

Abstract

The independent curriculum is a new breakthrough program provided by the Ministry of Education and Culture Nadiem Makariem to provide learning freedom to students and teachers in determining the learning process they are interested in. The independent curriculum is a form of improvement from the previous curriculum, namely curriculum 13 (K13). As a new education system, it must have changes in the education process compared to the previous curriculum. This has led to different positive and negative responses from teachers. For this reason, researchers are interested in describing how the perceptions of teachers, especially chemistry teachers, regarding the implementation of the independent curriculum at SMA Negeri 9 Manado. This research was conducted offline by distributing printout questionnaires to 6 chemistry teachers at SMA Negeri 9 Manado. The questionnaire in this study was analyzed using a Likert scale. The results showed that the perception of chemistry teachers regarding the implementation of the independent curriculum was classified as a good category with a percentage of 71%. Teachers agree and even strongly agree on the concept of freedom of learning which focuses on changing student character. The teachers also agree with the concept of freedom of learning offered in the independent curriculum, because students and teachers are free to choose learning media, as well as the concept of independent learning by students with a learning system that can be accessed anywhere and anytime by students. They also disagreed that character surveys for graduation requirements could

Abstract

Indonesia, negara kepulauan dengan banyak gunung berapi, adalah rumah bagi Gunung Ruang, yang terletak di Kabupaten Tagulandang, Provinsi Sulawesi Utara. Penelitian ini bertujuan untuk mengidentifikasi gugus fungsi yang terdapat pada abu letusan Gunung Ruang pada Mei 2024. Identifikasi gugus fungsi pada abu vulkanik menggunakan spektroskopi FT-IR pada rentang bilangan gelombang 4000-400 cm⁻¹. Persiapan sampel melibatkan sintesis fisik menggunakan metode top-down, diikuti dengan analisis FT-IR. Hasil FT-IR menunjukkan gugus fungsi dominan pada sampel abu. Penelitian menunjukkan pita serapan yang kuat pada 509 cm⁻¹, menunjukkan adanya gugus lentur siloksan (Si-O-Si), dan pada 1784 cm⁻¹, menunjukkan adanya ikatan C=O. Puncak yang teramati pada 2362 cm⁻¹, berhubungan dengan peregangan C=O pada CO₂, dan intensitas yang kuat pada 3371 cm⁻¹, menunjukkan vibrasi hidroksil (OH) pada gugus silanol (Si-OH). Kesimpulannya, analisis FT-IR mengidentifikasi senyawa silika (SiO₂) pada sampel abu vulkanik Gunung Ruang.

Abstract

This research is classroom action research which aims to improve student learning outcomes in chemical bonding material through the application of the project based learning model. There are several things that underlie this research, namely the low interest in student learning in chemistry subjects which then makes student learning outcomes unsatisfactory. The research carried out is classroom action research (PTK) which takes place in two cycles, in cycle I it is held three meetings and in cycle II it is held two meetings. Each cycle in this research consists of a planning stage. implementation, observation and reflexology Data collection techniques were carried out using observation sheets and written tests. Based on the research results, it was found that the project based learning model could improve student learning outcomes. This can be seen from the percentage of student learning outcomes which increased from 60% in cycle I which then increased to 96% in cycle II.
