Abstract

Ethnochemistry is the study of chemical practices by specific cultural groups that are used for activities following the ideology of the community, including the Banjarese community. Banjar ethnochemistry can be integrated into science learning, especially for Indonesia’s senior high school chemistry learning context. This study aims to analyze the results of exploring the local wisdom of the Banjarese community, which is included in ethnochemistry, and to take an inventory of Banjar ethnochemical knowledge as a source of Indonesia senior high school chemistry learning. The study uses an exploratory qualitative approach with ethnographic methods. The subjects in this research are community leaders and academics who understand Banjar ethnochemistry. Data collection techniques used interviews, observation, and documentation. The results of the Banjar ethnochemical exploration include Banjar soup, sasirangan, basungu, rub ash, batimung, sepat dry fish, diamond, tanggui, tapai Gambut, laduman, kelakai, ironwood, ironwood hair oil, fish pentol, selangat shredded fish, Mangurak wells, mandai, and lahang ice. An inventory of Banjar ethnochemical knowledge that can be used as a source for Indonesia senior high school chemistry learning consists of acids and bases, chemistry and its scope, alkane derivatives, macromolecules, elemental chemistry, and colligative properties of solutions.

Abstract

Most chemical concepts are abstract, hierarchical, and constructed from basic to complex concepts. Lewis structure, VSEPR theory, molecular geometry, and molecular symmetry have hierarchical idea. This study attempted to characterize and determine the relationship between students’ knowledge of Lewis structure, VSEPR theory, molecular geometry, and molecular symmetry of the 1st, 2nd, and 3rd-year chemistry students at a public university. This study involved 88 students in total selected using proportionate stratified random sampling. The instrument was a relevant short-answer question on the three topics. The data were measured using nonparametric statistics, especially the Kruskal-Wallis difference and Spearman Rank correlation tests.  This study’s results show differences in understanding of Lewis structure, molecular geometry, and symmetry between the 1st, 2nd, and 3rd-years students. The 3rd-year students always performed better than the 1st and 2nd-year students for all topics. The test result confirms a positive and strong relationship between students’ understanding of Lewis structure and molecular geometry for the three groups of students with ρ values of 0.979, 0.979, and 0.966 (< 0.01) for 1st, 2nd, and 3rd-year students, respectively.
