Abstract

The review means to decide the viability of personal selling in drawing in understudies during the confirmations cycle. Implementing a variety of marketing strategies, including product, pricing, promotion, and presenter strategies, is frequently necessary for the success of businesses, including educational establishments. It is believed that a key strategy for attracting prospective students is the presenter's role. The exhibition of moderators can be estimated by inspecting the proportion of candidates who come to enroll and thusly become new understudies. Maintaining a balance between registered applicants, accepted students, and incoming prospects appears to be a problem. The Jakarta ABC Polytechnic is the specific focus of the study, which is a school that focuses on training workers who are ready for work and developing human resources. The research takes a quantitative approach with the goal of describing and analyzing the role that presenters play in marketing educational products across the archipelago for professional development and educational institutions. To direct the investigation, the specialists mean to use SPSS Rendition 24, a measurable programming bundle generally utilized for information examination. SPSS can help with coordinating, breaking down, and deciphering quantitative information, permitting the scientists to reach significant determinations from their exploration discoveries.

Abstract

E-wallet is an electronic device, online service, or software program that allows one party to make electronic transactions with another party bartering digital currency units for goods and services. This can include purchasing items on-line with a computer or using a smartphone to purchase something at a store. Currently in Indonesia there are many kinds of E-Wallets including; DOKU, BBM money bank Permata, cash XL, Telkomsel T-Cash, CIMB Niaga Mobile Account, and so on. One example of an E-wallet is Gopay, inaugurated in April 2016 that can be used in all payment transactions in the Gojek application. This study aims to investigate the effects of E-wallet and Sales Promotion of Hop Hop Purchasing Decisions among high school students in the city of North Jakarta. This is explanatory research using probability sampling method and using a questionnaire on Google Form for collecting data. The sample used is 100 respondents from high school students who use the GOPAY electronic wallet to buy Hop Hop in the city of North Jakarta. This research uses quantitative analysis: validity, reliability, classic assumptions, correlation coefficient, determination coefficient, simple and multiple linear regression, hypothesis significance of t test and F test. The results of multiple linear regression analysis show that there was an effect of E-wallet and Sales Promotion on purchasing decisions. The variable correlation coefficient of the use of E-wallet and Sales Promotion on the GOPAY E-wallet has a strong relationship.

Abstract

Sargassum is a genus of seaweed that is known to contain fucoxanthin. The increasing incidence of health issues related to antimicrobial resistance (AMR), free radicals, and ultraviolet (UV) radiation has prompted the exploration of natural compounds as alternative sources of pharmaceutical agents. Fucoxanthin possesses the ability to protect cells from oxidative damage and offers a wide range of health benefits. This study aimed to evaluate the potential of fucoxanthin derived from Sargassum polycystum as an antioxidant, antifungal, antibacterial, and photoprotective (sunscreen) agent. The research methods included the extraction and isolation of fucoxanthin using Open Column Chromatography (OCC), phytochemical screening, thin-layer chromatography (TLC), antibacterial and antifungal assays, antioxidant activity assessment using the DPPH method, and determination of the Sun Protection Factor (SPF). The results showed that the extract of Sargassum polycystum contains secondary metabolites such as flavonoids, alkaloids, tannins, steroids, and saponins. The fucoxanthin fraction was successfully isolated, characterized by a distinct absorption peak at 447.5 nm and a retention factor (Rf) value of 0.93. The fucoxanthin fraction showed antibacterial activity against Staphylococcus aureus, as well as antifungal activity against Trichoderma sp. and Candida albicans. The antioxidant activity of the fucoxanthin fraction was categorized as strong, with an IC50 value of 67 ppm. Its photoprotective ability was classified as maximal, with a Sun Protection Factor value of 13.71. The fucoxanthin fraction derived from Sargassum polycystum exhibits promising potential as an antibacterial, antifungal, antioxidant, and photoprotective agent, and may serve as a valuable natural resource in pharmaceutical and cosmeceutical applications.
