Abstract

Soap, as a cleaning agent, is produced through a saponification reaction between oil and a strong base (NaOH), producing glycerol as a by-product. In this case, experiments were carried out using the cold process method to explore making soap with the addition of papaya extract. This research also involves analyzing the quality of soap through organoleptic tests and acidity degree (pH) analysis. The organoleptic test results showed that the soap had an appropriate texture, sufficient foam, and an attractive color after dyeing. Implementation of the saponification reaction with NaOH requires precision and accuracy of measurements for the success of the process. Apart from that, the use of essential oils and the proportion of NaOH affect the quality of the soap. The curing process is carried out for ± 30 days to optimize the quality of the soap. This research aims to produce good quality soap, with a focus on evaluating organoleptic tests and acidity levels as indicators of success.

Abstract

Biology teaching requires teaching resources that can help pupils gain a deeper understanding of abstract and complex concepts. One possible solution is to develop e-LKM supported by Liveworksheets using a deep learning approach. This article aims to review findings from previous studies egarding e-LKM development, the implementation of Liveworksheets, and the application of the deep learning approach in learning. The study employed a literature review method, examining relevant journal articles published between 2022 and 2026. The findings show that the application of a deep learning approach in the development supports active, meaningful and student-centred learning while contributing to better conceptual understanding and critical thinking skills. Furthermore, Livewroksheets facilitates the creation of interactive, practical and easily accessible e-LKM through multimedia features and digital assessment tools, thereby enhancing student engagement in learning. In Biology lessons, combining Liveworksheets with the deep learning approach can help present abstract and complex concepts in a more concrete manner. Consequently, e-LKM developed with the support of Liveworksheets and a deep learning approach can serve as an innovative alternative for promoting Biology learning that is more effective, interactive and meaningful.
