Design and Testing of Chemistry Learning Media in The Form of Weblog-Based Android Applications on Hydrocarbon and Petroleum Materials

Abstract

ABSTRACT. This research focuses on the design and testing of chemistry learning media in the form of a web;og-based Android application for hydrocarbon and petroleum topics. The study aims to assess the validity, practicality, and student responses to this mobile learning tool. Conducted at SMA Negeri 1 Tambang, the research follows a research and development (R&D) methodology based on the Borg and Gall model. Data were collected through interviews, literature reviews, and questionnaires, targeting both teachers and students. The learning media, created using appsgeyser, integrates materials, quizzes, animations, and assignments to enhance engagement and comprehension. The findings indicate that application is valid, with assessments from media and subject matter experts achieving scores between 80% and 95%. Student feedback shows that 70% found the media easy to use, while 100% described it as engaging. Furthermore, teachers reported a high level of practicality in its use. Overall the use of this weblog-based Android application holds potential for improving student motivation and understanding of complex chemical concepts, particularly hydrocarbons and petroleum. Future recommendations include broader implementation and further refinements to the media content based on trial feedback.
