Abstract

Liquid smoke resulting from pyrolysis of durian skin has antibacterial potential which is used as a basic ingredient for making bio hand sanitizer. Durian skin is difficult to degrade because it contains high levels of lignin, cellulose, and hemicellulose compounds, so with the use of durian skin, it is expert that it will be able to reduce durian skin waste. Bio hand sanitizer is formulated with essential oils to reduce the pungent aroma of smoke. This study aims to determine the antibacterial activity and characteristics of the durian skin liquid smoke bio hand sanitizer. This study used the Completely Randomized Design (CRD) method, with a comparison between durian peel liquid smoke and orange peel extract and the addition of 10 mL NaOH (1:3, 1:1,57, 1:1, and 3:1). The results of research based on characteristic tests obtained pH values of 4.81-7.36, viscosity 1392-3664 cps. Formula E (3:1) emerged as the best sample through organoleptic tests on each bio hand sanitizer preparation formula. It exhibited a yellow color, a runny texture, and a smoky aroma with the mixture. The antibacterial test demonstrated that the bio hand sanitizer preparation possessed antibacterial activity, and the resistance diameter for the test bacteria S. Aureus and E. Coli ranged from 21.51 to 31.14 mm

Abstract

This study examines the impact of physical evidence, religion, and personal intimacy on customer loyalty at Bank Syariah Indonesia, while also assessing the moderating influence of brand image and switching barriers. The study employed a quantitative methodology to survey 230 clients. Data were gathered via a Likert-scale questionnaire and examined using SEM-PLS. The results demonstrated that brand image was the foremost determinant of customer loyalty, followed by physical proof and religiosity. Customer closeness did not exhibit a substantial direct impact on loyalty. Nonetheless, switching barriers, albeit not immediately impactful, acted as a moderator between physical evidence and consumer loyalty. The brand image substantially influences the relationship between religiosity and loyalty. This study contributes to the literature on sharia marketing by emphasizing the critical function of brand image in fostering customer loyalty and the significance of physical evidence in generating favorable customer experiences. The report offers strategic ideas for Sharia Bank management to elevate brand image, develop physical infrastructure, and incorporate Sharia principles into their services.
