Abstract

Alphitonia incana, also known locally as balik angin, is an endemic natural antioxidant plant of Borneo. The objective of the present work was to compare the effectiveness of maceration and Soxhlet extraction of balik angin leaves with respect to antioxidant activity and phenolic–flavonoid content. Ethanolic extracts were prepared using both extraction methods, and the phenolic-flavonoid content was quantified spectrophotometrically. Antioxidant performance was assessed through DPPH, CUPRAC, and FRAP assays. The findings revealed that the Soxhlet-derived extract contained higher concentrations of phenolic-flavonoid compounds than those produced by maceration. In addition, the Soxhlet-derived extract demonstrated stronger antioxidant activity, as evidenced by lower IC₅₀ and EC₅₀ values in the DPPH (10.872 ppm) and CUPRAC (6.578 ppm) assays compared with the macerated extract (IC₅₀ 13.127 ppm; EC₅₀ 14.034 ppm) and was classified as a very strong antioxidant. The FRAP assay further supported these results, with ferric reducing power values of 1,484.1 mg AAE/g extract for the Soxhlet-derived extract and 1,295.8 mg AAE/g extract for the macerated sample. Overall, the study concludes that Soxhlet extraction is more effective than maceration in enhancing the antioxidant potential of balik angin leaf, a result that is closely associated with their elevated phenolic and flavonoid content.

Abstract

One example of technology advancement is Shopee Paylater, which makes it simple to shop using a buy now, pay later model. However, notwithstanding if such transactions are permitted in Islam or not, individuals are still cautious to use it. The purpose of this study is to ascertain and evaluate the usage of Shopee Paylater and an analysis of Shopee Paylater electronic money loans in light of Islamic law. The approach used is descriptive qualitative research, namely library research, where the author discusses the use of Shopee Paylater electronic money before studying it from the perspective of Islamic law. The findings of this study demonstrate that utilizing Shopee Paylater is not permitted since it violates sharia principles in a number of ways, including various requirements that contain riba and need additional payments and fines, as well as several aspects that go against a Fatwa. DSN-MUI No: 116 / DSN-MUI / IX / 2017 also mentions the usage of electronic money acquired without making a deposit first but instead in the form of loans given in the form of limit, although the limit obtained cannot be discharged in physical form and contains riba. By employing an ijarah contract as a type of application rental fee, further charges or usury can be avoided. However, if paylater online shopping is only used as a means of payment for products, there are no usurious transactions involved, and there are no additional costs while paylater online shopping is used, then this is permitted.
