Abstract

Retirement is considered a worrying time, especially for those who are not mentally prepared. This study aims to develop a retirement preparation scale based on a psychometric approach. The survey design used a correlation approach with the survey data collection technique. The respondents are the employees at PT. Pembangkitan Jawa Bali (PJB) (N = 57). The retirement scale developed includes five dimensions: Physical, mental, financial, performance, and health assessment. To test the internal structure of the scale, a content validity test was conducted using Aiken V and Confirmatory Factor Analysis. The results show that the measuring tool for retirement readiness fits the existing data in the field. To measure the retirement readiness of employees at PT PJB, 17 items consisting of two open-ended questions and 15 Likert scale items can be applied. The results also indicate that the measurement tool for employee retirement readiness of PT. PJB is valid and reliable to be applied within the scope of PJB's subsidiaries.

Abstract

The aim of the research is to synthesize the compound of Precursor of ABA from MSG the starting material by structural modification as well as to determine the characteristics and physical properties of the synthesis compound. It was done by modification of chemical structure starting with glutamic acid isolation from MSG. Then it isolate reacted with AlCl3 to obtain the ABA compound precursor. The rendemen was 18.5%, of synthesis identification obtained of white powder, odorless, dissolves in hot water and melt at a temperature of 187-189 0C. The UV-Vis spectrophotometry showed that the synthesis process formed a new compound. Confirm with HPLC analysis.

Abstract

Antiviral Properties and Potential of Ginger (Zingiber Officinale) and Its Derivatives: A Systematic Review. Ginger has long been valued in traditional medicine for its therapeutic benefits. Recently, its antiviral capabilities have attracted significant interest, highlighting its potential as a natural antiviral agent. This systematic review seeks to thoroughly evaluate the antiviral effects of ginger and its active compounds, providing valuable insights to support future research and clinical applications in natural antiviral therapies. A comprehensive electronic search was undertaken across PubMed, Embase, and Scopus databases, employing MeSH terms, Emtree, and relevant synonyms to capture studies on ginger and its antiviral effects. The initial search yielded 531 records, which were de-duplicated and subsequently screened by title and abstract using Rayyan software. Fourteen studies specifically addressing antiviral effects against human pathogens met the inclusion criteria. This systematic review was conducted in strict accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to ensure rigorous reporting of findings. The majority of included studies were in vitro, revealing anti-viral effects of ginger against various viruses, including Influenza A, Chikungunya, Dengue, hRSV, HSV-2, and SARS-CoV-2 in different cell lines across various concentrations. In addition, Ginger extracts also demonstrated efficacy against Influenza A in both in vivo and in ovo studies, and a randomized controlled trial showcased encouraging antiviral effects targeting SARS-CoV-2. Ginger shows promising antiviral effects in most of the in vitro studies. Translating these findings to in vivo models is imperative for clinical relevance. Further in vivo research is essential before progressing to human studies to ascertain ginger's potential as an effective antiviral agent
