Abstract

Penelitian ini bertujuan untuk mengetahui kesulitan pemahaman konsep pada materi titrasi asam basa siswa SMA. Penelitian ini menggunakan metode deskriptif dengan data hasil penelitian diperoleh dari hasil tes siswa. Instrumen yang digunakan yaitu tes uraian, wawancara dan dokumentasi tentang materi titrasi asam basa. Penelitian ini dilakukan di SMA Percontohan UPI dengan subjek sebanyak 30 orang siswa SMA Kelas XII IPA yang telah mempelajari materi titrasi asam basa. Kesulitan pemahaman konsep yang dialami oleh siswa yaitu siswa kesulitan dalam menjelaskan pemilihan indikator sebanyak 53,33%, siswa kesulitan dalam menuliskan persamaan dan menyetarakan persamaan reaksi asam sulfat dan natrium hidroksida sebanyak 56,65%, siswa kesulitan dalam menentukan konsentrasi asam yang bervalensi dua sebanyak 70,00% dan 10,00% kesalahan siswa dalam menentukan konsentrasi asam dan basa bervalensi satu. Siswa kesulitan dalam 86,66% siswa tidak dapat menentukan jenis titrasi berdasarkan kurva dan siswa kesulitan dalam menentukan jenis zat pada setiap daerahsebesar 80,00%. Faktor penyebab kesulitan pemahaman konsep yang dialami siswa disebabkan oleh cara mengajar guru dan siswa itu sendiri.

Abstract

Ethno and science provide a dimension of togetherness in the development of society's culture and science. The aim of the study was to determine the perceptions of prospective chemistry teachers towards ethnoscience in contextual-based learning. The method used in this research is qualitative. Sources of data were taken from 39 first and second level chemistry teacher candidates and then specified into seven tribes in seven districts/cities in South Sumatra. The research instruments are surveys, interviews, and observations. Data were analyzed based on an interactive analysis model. The data analysis technique is to reduce the data and then draw conclusions. This study shows a positive perception of prospective chemistry teachers towards ethnoscience, that is, they are able to understand and elaborate on the ethnoscience approach in basic science lectures. The main problem faced by prospective chemistry teachers in the ethnoscience approach is that they are not used to connecting science content based on the chemical context with local culture. Ethnoscience approach can be implemented with Contextual Learning. This learning provides an opportunity for prospective chemistry teachers to further explore the culture of the surrounding community in a more real way. Contextual Learning helps and bridges the process of discovering concepts and contexts that exist in learning.
