Abstract

This study aims to develop a Student Worksheet (LKPD) design for the topic of Biological Technology Innovation in Grade X of Senior High School through the enrichment of functional beverage production in the form of water kefir made from pineapple (Ananas comosus (L.) Merr.) with the addition of cinnamon and different types of sugar. The research was conducted from October 2024 to February 2025 at the Biology Education Laboratory, University of Riau. The method used was an experimental approach with a completely randomized design (CRD) in a factorial pattern consisting of two factors: types of sugar (granulated sugar and palm sugar) and cinnamon concentration (0%, 1%, and 3%), with each treatment replicated three times. The observed parameters included organoleptic and hedonic tests. The results showed that the best combination was found in the treatment using palm sugar and 10 grams of cinnamon (G2K1). This water kefir was preferred by the panelists due to its mild sourness and a balanced aroma of fermentation and cinnamon. The findings of this study were subsequently integrated into the LKPD design and validated by subject matter and media experts, indicating its feasibility as an instructional material for biotechnology learning in high school.

Abstract

The problem of acne (Acne vulgaris) is a common skin condition among adolescents and is generally triggered by the growth of Propionibacterium acnes. Various natural-based treatment alternatives have been developed to minimize the side effects associated with chemical agents. Mangosteen (Garcinia mangostana L.) pericarp and ciplukan (Physalis angulata L.) leaves are known to contain diverse secondary metabolites such as xanthones, flavonoids, tannins, saponins, alkaloids, and triterpenoids, which have potential antibacterial properties. This study aims to determine the antibacterial activity of the combined extracts of mangosteen pericarp and ciplukan leaves against Propionibacterium acnes, as well as to develop the research findings into a poster design for the Innovation in Biological Technology learning material for Grade X SMA. The research employed an experimental method using 15 treatment variations of extract combinations. Antibacterial activity was tested using the disk diffusion method on Nutrient Agar medium. Observed parameters included extract yield, phytochemical screening, inhibition zone diameter, and macroscopic and microscopic observations of the test bacteria. The results revealed that both extracts tested positive for active antibacterial metabolites. The antibacterial activity of the extract combinations showed varying inhibition strengths, with several treatments categorized as weak to moderate. The best treatment, P9 (35% mangosteen extract + 35% ciplukan extract), produced a strong inhibition zone measuring 14.14 mm. These findings indicate that the combination of extracts exhibits a synergistic effect in inhibiting the growth of Propionibacterium acnes. The research findings were further developed into a poster design for the Innovation in Biological Technology material for Grade X SMA. Expert evaluations from media and material specialists indicated that the poster is feasible to use as an innovative, informative, and contextual learning medium. The combination of mangosteen pericarp and ciplukan leaf extracts has potential as a natural antibacterial agent for acne control.
