The lack of availability of learning resources in the form of teaching materials is one of the problems found in chemistry learning, both in secondary schools and in tertiary institutions, so it is very urgent to develop contextual chemistry teaching materials as an implementation of the ethnochemical approach in learning. The purpose of this study was to explore and develop chemistry teaching materials as learning resources by exploring the potential of local Sasak and Javanese wisdom. This research approach uses a qualitative approach with data collection techniques through literature, interviews, and documentation. The data obtained were analyzed using Miles & Huberman's qualitative analysis. The research subjects consisted of community leaders, chemical content experts, and chemical literature relevant to the research study. Based on the research findings, it can be concluded that Sasak and Javanese local wisdom can be used as a source of chemistry learning through integrating Sasak and Javanese local wisdom with chemical bonding materials and changes in elements, compounds, and mixtures. Thus, the implications of this research can be a source of reference in developing contextual chemistry teaching materials so as to make learning more meaningful.

The Covid-19 pandemic caused a transformation in the implementation of learning from offline/face to face to online learning. This study aims to analyze the effect of online learning methods on students' learning interest during the Covid-19 pandemic. Online learning is very beneficial for maintaining learning communication between teachers and students. This research is based on the one-group pretest-posttest method. Where the initial ability of students is obtained through the Pretest before the lecture, and student learning outcomes are obtained from the Posttest which is carried out after the lecture using the online method. The research was conducted on 21 students who took acid-base chemistry courses. The data analysis technique used is simple linear regression analysis. From the research results, it was found that the average score of students in the Pretest was 59.5 and the average score of students in the Posttest was 74. Meanwhile, the response results showed that online learning methods had a positive, although not significant, effect on students' interest in learning during the Covid-19 pandemic. This means that the better the quality of online learning, the higher the learning interest of students. The magnitude of the influence of online learning methods on students' learning interest is only 3.8%. That means that even though it is not significant, the lecturer's ability to carry out online learning methods still has an influence on students' interest in learning.

As one of the sciences, some students consider chemistry complex and abstract, so many misconceptions arise. One of the chemistry topics that cause many misconceptions is hydrocarbons. A misconception is an understanding of concepts in students' minds that are contrary to scientific concepts. This research aimed to identify the student’s understanding and misconception of hydrocarbon. The study was qualitative descriptive research. Qualitative descriptive research was used to identify student misconceptions using the four-tier test. The sample of the research was 24 students. The instruments used in this research are four test levels which include (1) multiple-choice, (2) confidence rating of the answer beliefs, (3) reason for the answer, and (4) confidence rating of the reasoning. The result shows that 24,7% of students well-understood hydrocarbon concepts, 32,1% do not understand, and 43,2% have misconceptions. Misconceptions in this research are divided into three categories: low, moderate, and high. The students experience misconceptions with high criteria on the concept reaction of hydrocarbon (66,7%), moderate criteria on the concept of determining hydrocarbon compound (31,3%), the nomenclature of hydrocarbon compound (56,3%), types atom carbon (37,5%), Physical and Chemical Properties (45,8%), isomers (47,9%) and low criteria on the concept of characteristics of carbon atoms (16,7%).
