Abstract

Currently, the implementation of the Halal assurance system in Indonesia is mandatory. A side from food, pharmaceutical, cosmetics, and medicines must all be halal certified. Natural products, particularly marine-based products, are an alternative choice for the cosmetics and pharmaceutical industry's raw materials. Enhalus acoroides are common along Indonesia's coasts and have the potential to be used as raw materials in halal cosmetics and pharmaceutical products. The purpose of this paper is to examine the potential of E. acoroides samples collected from various locations in Indonesia in terms of bioactive compounds and their applications. Secondary metabolites namely alkaloids, flavonoids, polyphenols, steroids, triterpenes, and tannins have been reported in E. acoroides extract from Indonesia, and they have the potential to be used as antibacterial, antiaging, antiviral, antitumor, and antioxidant in the pharmaceutical and cosmetic industries in Indonesia

Abstract

Based on a preliminary survey, students at Grade X SMK IT Darussalam Boarding School 01 Batam demonstrated a low understanding of mathematical concepts. This study aimed to examine: (1) the effect of Heyzine Flipbook-based digital learning media on students’ mathematical concept understanding, (2) the effect of conventional learning, and (3) the differences between the two methods. Using a quantitative approach, the population included all Grade X students in the 2025/2026 academic year. Purposive sampling was applied, with Grade X TKJ A (24 students) as the experimental class and Grade X TKJ B (19 students) as the control class. Data were collected through essay tests, consisting of three validated and reliable items. Data analysis involved assessing normality and homogeneity, as well as conducting hypothesis tests. The results revealed that: (1) Heyzine Flipbook significantly improved students’ understanding of mathematical concepts, (2) conventional learning also showed an effect on students’ understanding, though at a lower level, and (3) a significant difference was found between the two approaches, with Heyzine Flipbook proving more effective in enhancing students’ mathematical concept understanding.
