Cosmetics are one of the products to improve appearance which are increasingly widely used in Indonesia. However, the large number of cosmetic uses is not in line with the quality. In recent years, Badan Pengawas Obat dan Makanan (BPOM) has noticed an increase in the spread of illegal cosmetics in Indonesia. Educational videos are one practical medium that can be used to promote the dangers of illicit cosmetics. This community service program aims to increase public understanding of the dangers of illegal cosmetics circulating on the market. Community service activities are created by creating educational materials and videos that are disseminated to the public directly or via social media. So that through this educational video, the public can understand it well. The activities then looked at the public's initial level of understanding of the dangers of cosmetics by conducting a pre-test. After that, the videos and materials that had been prepared were shown, and then the public's knowledge increased through the post-test. From the results of the pre-test and post-test, it was found that public understanding of the dangers of cosmetics increased by 17.1%. So it can be concluded that this service activity successfully educated the community.

Inflammation is a mechanism in the body's defense system that occurs through the release of pro-inflammatory mediators. However, inflammation needs to be controlled because it triggers excessive production of inflammatory mediators that cause tissue damage and disease progression. Various types of first-line anti-inflammatory therapy drugs have potential for adverse side effects such as anemia, hypertension, and immunosuppression, so alternative anti-inflammatory agents are needed that are considered safe and effective. The red betel plant (Piper crocatum Ruiz and Pav) is known to contain secondary metabolites such as sesquiterpenes, aldehydes, phytosterols, and sterols that are already known as anti-inflammatory agents. This study aims to determine the anti-inflammatory potential of the red betel plant based on pharmacological network analysis. The test compounds are secondary metabolites that were successfully detected in the red betel stem such as caryophyllene, octadecadienal, stigmasterol, and sitosterol. Proteins related to anti-inflammatory activity obtained from GeneCards, proteins interacting with test compounds predicted by SwissTargetPrediction, and the results of the intersection of both types of proteins were further analyzed using STRING with Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment methods. GO and KEGG enrichment analysis showed involvement in NF-?B, IL-17, PI3K/AKT, and TNF signaling pathways, with 16 key genes related to anti-inflammatory activity targets. The main target proteins of caryophyllene and stigmasterol being HSP90AA1 and STAT3, respectively, while octadecadienal and sitosterol showed NFKB1 as the same main target protein. The results provide a scientific data for the use of these secondary metabolites as anti-inflammatory agents.

Type 2 diabetes mellitus (T2DM) remains a significant global health challenge, responsible for more than 90% of all diagnosed diabetes cases worldwide. The progression of T2DM is primarily driven by insulin resistance and progressive pancreatic β-cell dysfunction, both of which contribute to various metabolic complications. Metformin is widely used as a first-line antidiabetic drug. However, its long-term use is associated with gastrointestinal disturbances, lactic acidosis, and vitamin B12 deficiency. These limitations highlight the need for safer and more effective therapeutic alternatives. β-caryophyllene, a sesquiterpene compound derived from the stem extract of Piper crocatum Ruiz & Pav., has demonstrated antioxidant, anti-inflammatory, and antilipidemic properties that may support its potential as an antidiabetic agent. This study evaluated the pharmacological potential of β-caryophyllene as an antidiabetic agent through an in silico approach. The analysis included drug-likeness assessment via Lipinski’s Rule of Five, ADMET profiles, network pharmacology, such as KEGG pathway and GO, inhibitory activity prediction using SVM regression in DataWarrior, and molecular docking through AutoDockTools and BIOVIA Discovery Studio, with metformin used as a reference standard. β-caryophyllene fully complies with Lipinski’s Rule of Five, indicating good drug-likeness and potential for oral bioavailability. The IC50 prediction results indicated that β-caryophyllene exhibited stronger inhibitory potential than metformin against several key T2DM-related proteins, including IL6, HSP90AA1, NOS3, TLR4, KRAS, and NFKB1. Consistently, molecular docking analysis demonstrated that β-caryophyllene also had stronger interactions with these targets, exhibiting higher binding affinities compared to metformin. These proteins are implicated in insulin resistance, inflammation, and vascular dysfunction. Additionally, pharmacokinetic data demonstrated high intestinal absorption (94.8%), extensive distribution (VDss ≈ 4.49 L/kg), minimal CYP450 inhibition, and limited toxicity risks. Collectively, β-caryophyllene exhibits good pharmacological properties and multitarget activity, supporting its candidacy for further in vitro and in vivo studies as a potential therapeutic agent for T2DM.
