Abstract

Environmental pollution due to inappropriate waste management is a global problem. Open dumping and burning of waste in the open are the main waste management practices often applied to low-income countries. The biggest environmental problem in Indonesia is usually garbage. Generally, the waste that is often found in the school environment is organic and inorganic. Plastics, drink bottles and paper are examples of the types of inorganic waste often found in the school environment. This study aims to determine students' perceptions of organic and inorganic waste grouping as well as waste management and utilization. The data collection technique is to use a closed questionnaire. A total of 15 items and a total sample of 29 people. The data obtained from the questionnaire results are then made in narrative form. Based on the results of the research, some students have not been able to distinguish between organic and inorganic waste. The lack of available trash bins in the school environment can trigger students to care less about disposing of garbage in its place, some students do not also know waste management and utilization.

Abstract

The impulse that arises in students to be able to learn well is called learning motivation. Student response is a tendency arising from students towards learning that is applied. This research is a quantitative study to determine the correlation between learning motivation and response to hydrocarbon learning using Chemsketch. The study was conducted at SMAN 2 Merauke in Class XI Science 1 with 28 students. The sampling technique is simple random sampling. The research data were obtained using a questionnaire of learning motivation and student responses. The research data were analyzed descriptively and the results were obtained: (1) student motivation: 11 people (40%) were in the very high category and 17 people (60%) were in the high category, (2) student responses: 12 people (43% ) is in the very good category and 16 people (57%) are in the good category. Quantitative data analysis by testing the correlation between learning motivation and learning outcomes with the assumption of data linearity assumptions and data normality. After analyzing the results obtained that (1) there is a linear and significant relationship, (2) data is normally distributed, (3) there is a significant relationship between learning motivation and student response

Abstract

Buku teks dan kurikulum dianggap sebagai alat pendukung bagi guru. Khusus perubahan kurikulum menjadi kurikulum 2013, buku teks yang digunakan guru dan siswa harus memenuhi standar sesuai kurikulum 2013. Tujuan dari penelitian ini adalah untuk menganalisis buku-buku kimia yang digunakan oleh sekolah binaan di sekolah menengah atas dan sekolah menengah kejuruan. Jenis penelitian ini adalah penelitian deskriptif dan pengumpulan data dilakukan dengan wawancara kepada guru kimia dan angket untuk menganalisis buku-buku kimia topik larutan elektrolit dan nonelektrolit. Analisis dilakukan terhadap empat jenis buku kimia dengan penerbit yang berbeda. Dari hasil analisis, buku A dikategorikan layak digunakan dengan persentase kelayakan sekitar 81,6%, buku B memiliki persentase 74% dikategorikan cukup layak, buku C dengan persentase 50% dikategorikan tidak layak dan buku D dengan persentase 35% dikategorikan tidak layak.
