Abstract

Corn is a popular ingredient in facial skin care products. Corn contains thiamine, which can dry wounds and eliminate acne scars that appear as holes on the face or black spots. Corn starch is made into a gel mask with the gelling ingredient hidroxy prophyl methyl cellulose (HPMC). This research intends to establish if a gel mask manufactured from sweet corn starch (Zea mays saccharata) can meet the requirements of the physical quality test assessment results, as well as the stability requirements. The research approach is experimental, employing a sample gathering methodology known as purposive sampling. The evaluation of gel mask preparations includes evaluating the physical quality of the preparations, irritant testing on 10 participants, and drying time tests on the preparations. The evaluation of the preparations revealed that all gel mask formulations were semi-solid gels with a yellowish white color and a distinct corny smell. The results were homogeneous, with an average pH of 7.5–7.7, spreadability of 5–7 cm, and viscosity of 22133-67566. The preparation also exhibited stable stability at room temperature and did not irritate volunteers' skin. Therefore, both the stability requirements and the physical quality test assessment results are satisfied by the preparation.

Abstract

Virtual Reality (VR) has emerged as a promising technological innovation in education and rehabilitation, particularly for supporting motor development and physical activity among children with intellectual disabilities. This study aims to map and synthesize existing empirical evidence on the effectiveness of VR-based interventions in improving motor skills and physical activity in this population. A scoping review was conducted following PRISMA guidelines by systematically searching ScienceDirect, ProQuest, and Google Scholar databases for articles published between 2019 and 2025. From an initial yield of 1,009 studies, eight articles met the predefined inclusion criteria and were included in the final analysis. The findings indicate that VR-based interventions, especially those integrating virtual and real-world games, consistently improve walking ability, object control, and gross motor skills. Several studies also reported gains in muscle strength and coordination, although evidence regarding balance improvement remains inconsistent. Despite its potential benefits, challenges related to accessibility, intervention design, and individual adaptability persist. Overall, VR represents a valuable and engaging tool for enhancing motor skills and physical activity in children with intellectual disabilities. Future research should emphasize targeted program development, long-term outcome evaluation, and interdisciplinary collaboration to optimize VR-based rehabilitation and educational interventions.

Abstract

Cinnamon (Cinnamomum burmanii) is one of the spices that can be used as cosmetic preparations in the pharmaceutical industry because it contains potent antioxidants. Examples of cosmetic products containing cinnamon are body scrubs, body showers, and moisturizers. This study aimed to determine the antioxidant activity of cinnamon extract using the DPPH method. Cinnamon was extracted using the maceration technique with 96% ethanol solvent, and phytochemical screening was carried out. The results of phytochemical screening from cinnamon bark extract were alkaloids, saponins, tannins, triterpenoids, and flavonoids. Antioxidant activity obtained an IC50 value of 25.35 ppm. Based on these results, the cinnamon extract has a very strong antioxidant activity value.
