Abstract

Technological developments have prompted the production of highly advanced smartphones. However, various advanced features cause smartphones to heat up quickly and emit more electromagnetic radiation, which harms human health. Smartphone protection is needed to solve these issues. This study aims to create a film from the S. trifasciata plant based on polyvinyl alcohol (PVA) to reduce electromagnetic and thermal radiation on smartphones. S. trifasciata plants were macerated with acetone and partitioned with n-hexane, dichloromethane, ethyl acetate, and water. The films were made by mixing PVA with the four fractions. Among the four layers of film, the PVA + water and PVA + ethyl acetate fractions reduced electromagnetic radiation by 25.34% and 2.64%, respectively, and smartphone heat by 3.82 °C and 2.8 °C, respectively, the largest reductions. The results of an LC–MS/MS analysis show that the compounds thought to be contained in both fractions and play a major role in reducing electromagnetic and thermal radiation in smartphones are di-(2-ethylhexyl) phthalate, diisononyl phthalate, and two steroidal compounds, namely, stigmasterol and ergosterol peroxide.

Abstract

Melanin is a crucial amino acid in determining human skin and hair pigmentation. Excessive melanin production can lead to hyperpigmentation and darkening of the skin. This study aims to assess the capability of Adenostemma platyphyllum as a tyrosinase enzyme inhibitor. It predicts its anti-melanogenic activity through molecular docking with proteins involved in the melanogenesis process. The in-vitro approach was conducted by determining the tyrosinase enzyme inhibition capacity, while the in-silico approach involved ligand binding to target proteins from melanogenesis pathways. The highest tyrosinase inhibition capacity was observed in the ethanol extract, with values of 9.74 Kojic Acid Equivalent (KAE)/g extract (L-tyrosine) and 17.91 (KAE)/g extract (L-DOPA). Molecular docking analysis showed that the binding of eriodictyol 7-O-sophoroside (ΔG = -9.7 kcal/mol) has the best energy affinity for the PKC-β protein, genistein (ΔG = -7.5 kcal/mol) for the tyrosinase-related protein-1 (TYRP1) protein, eriodictyol 7-O-sophoroside (ΔG = -10.2 kcal/mol) for the cGMP protein, vincosamide (ΔG = -7.2 kcal/mol) for the microphthalmia-associated transcription factor (MITF) protein, and dicaffeoylquinic acid (ΔG = -7.4 kcal/mol) for the β-catenin protein. Based on a comparison of in-vitro and in-silico studies, melanogenesis inhibition is more potent in the PKC-β and cGMP pathways than direct tyrosinase inhibition because they exhibit lower binding energy.

Abstract

Watermelon rind extract is rich in protein, citrulline, and lycopene, whereas orange peel essential oil contains vitamins A, C, and E. Both ingredients have demonstrated potential in preventing hair loss. This study aimed to develop an oleogel that combines these two components to address hair loss. The efficacy of the oleogel for promoting hair growth was evaluated in male DDY (Deutchland Denken Yonken) mice. The oleogel characteristics, including pH, viscosity, color, homogeneity, oil binding capacity, spreadability, and organoleptic evaluations, were assessed through physical quality tests. Organoleptic analysis was conducted with 30 respondents from IPB University to identify the most preferred oleogel formulation. The yield of watermelon rind extract was 28.88%, while the orange peel essential oil constituted 2% (v/w) of the formulation. The optimal oleogel contained 3% watermelon rind extract and 1% orange peel essential oil, resulting in 100% hair growth in the mice. All the formulations met the standard requirements for oleogels, with the most favored being Formula F3, which includes 1% watermelon rind extract and 3% orange peel essential oil. This research highlights the potential of watermelon rind extract and orange peel essential oils as effective nutrients for hair loss treatment.

Abstract

Cimanggu II Village, located in Cibungbulang Subdistrict, Bogor Regency, has several libraries. However, libraries and literacy interest in this village are still relatively low, as evidenced by poorly maintained facilities and low public understanding of literacy issues. The Pelita (Improving Children's Literacy through Participatory Learning and Ecosystem Development) program was implemented in Cimanggu II Village to address the low interest in reading due to the poor condition of the Lentera Community Reading Park (TBM) and the minimal community support. The objectives of this activity include improving children's literacy skills, revitalizing the Lentera Community Library, strengthening community and external stakeholder involvement, and creating an inclusive literacy environment. This program integrates Community Engagement, Enriched Learning Environment, and Fun Learning Method based on Maslow's Hierarchy of Needs theory. The Pelita Sehati subprogram focuses on revitalizing TBM facilities and digitizing data, while Pelita Cerdas emphasizes improving literacy through interactive activities such as storytelling, magic chemistry, reading aloud, book reviews, story writing, and reading-based creative projects. The results showed a significant increase in children's interest in reading, literacy skills, courage, creativity, and participation. Evaluation using the Logic Model confirms the relationship between inputs, activities, outputs, and outcomes, while the sustainability strategy using the Quadruple Helix Model strengthens multi-stakeholder collaboration. This program has succeeded in building an inclusive, sustainable, and impactful literacy ecosystem.

Abstract

Indonesia has long been known as a tropical country rich in various local cultivars of rambutan (Nephelium lappaceum L.), including Aceh Lebak (AL), Aceh Pelat (AP), Binjai (B), Gula Batu (GB), and Sikoneng (SK). Due to their phenolic and flavonoid compound, rambutan peel extracts have been reported to exhibit antioxidant and antiproliferative properties. Variation among cultivars suggests potential differences in bioactive compound content and biological activity. The objective of this study was to evaluate the antioxidant and toxicity profiles of five rambutan peel varieties and their correlation with total phenolic compound (TPC) and total flavonoid content (TFC). The antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, and phenolic and flavonoid contents were measured by colorimetric assays. Toxicity was assessed using the Brine Shrimp Lethality Test (BSLT). Bioautography analysis using TLC-DPPH was conducted to identify antioxidant-active compounds. In this study, all rambutan peel extracts indicated the presence of flavonoids, phenolics, saponins, steroids, alkaloids, and triterpenoids. The highest extract yield was observed in Sikoneng, also with the highest TPC and TFC values. The Binjai variety exhibited strong antioxidant activity (IC50 = 4.73 ± 0.19 mg/L) and three active antioxidant spots; however, it also exhibited toxicity (LC50 = 136.27 ± 6.58 mg/L). The correlation between total phenolic or flavonoid content and the observed biological activity was not statistically significant, indicating that additional metabolites or synergistic interactions may also contribute. These findings underscore the significant impact of biodiversity on differences in compound levels and potential biological activities among rambutan peel varieties.

Abstract

Biflavonoids are a distinctive class of dimeric flavonoids known for their diverse biological activities and chemotaxonomic significance. In this study, two biflavonoids were isolated from the acetone extracts of Araucaria hunsteinii twigs and Araucaria columnaris leaves collected from Bogor Botanical Garden, Indonesia. Chromatographic techniques, including Sephadex LH-20 column chromatography and preparative thin-layer chromatography, were employed for purification, followed by structural elucidation using LC-MS/MS and 1D/2D NMR spectroscopy. The compounds were identified as 4',4''',7,7''-tetra-O-methylcupressuflavone (1) and 7-O-methylcupressuflavone (2). Notably, this is the first report of 7-O-methylcupressuflavone isolated from A. columnaris leaves, providing new chemotaxonomic insights into the genus Araucaria. A literature-based pharmacological analysis revealed promising cytotoxic and α-glucosidase-inhibitory activities of the isolated compounds. These findings contribute to the phytochemical profiling and highlight the pharmaceutical potential of Araucaria-derived biflavonoids.

Abstract

Coptotermes curvignathus is a termite pest that attacks buildings, plantations, and forests. Controlling this pest requires environmentally friendly natural materials. The bintaro plant (Cerbera odollam) are known in Indonesia as natural insecticides and traditional medicines because of their strong toxic properties, so they have the potential to be used in termite control. This study evaluated the efficacy of C. odollam leaf and fruit peel extracts as natural termiticides and their effectiveness against subterranean termite C. curvignathus. The extraction process used three solvents with different polarities: n-hexane, acetone, and ethanol. Anti-termite bioactivity tests were conducted following the Japanese Industrial Standard (JIS) 1571-2010 method. Ethanol extract from C. odollam leaves produced the highest yield (9.52%). Phytochemical analysis showed the presence of alkaloids, flavonoids, phenolics, steroids, and saponins in both leaf and fruit peel extracts. The anti-termite bioactivity test showed that the leaf extract with acetone solvent caused 97.33% mortality, while the fruit peel extract with ethanol solvent caused 100% mortality at a 5% concentration. This study demonstrates that C. odollam leaf and fruit peel extracts have strong potential as natural termiticides.
