Abstract

Salted anchovies (Stolephorus sp.) are a long-known and popular delicacy among Indonesians. Salting is the most common method of preserving fish. Table salt (NaCl) is the most common and widely used method. The salting process takes a long time, leading traders who want to make large profits to add formalin to the fish to prevent it from rotting quickly and to preserve it for a long time. This study aims to determine whether anchovies sold at the Simpang Limun market in Medan City contain formalin and the levels of formalin identified in salted anchovies using the VIS spectrophotometry method. The research was carried out employing a purposive approach, and the samples analyzed were anchovies sourced from both the Simpang Limun market and the Modern Market. The independent variables in this research included anchovies, Schryver reagent, KMnO4 reagent, Schiff reagent, as well as VIS Spectrophotometry. To perform qualitative analysis of formalin, KMnO4 reagent, Schryver reagent, and Schiff reagent were utilized, while the quantitative analysis was conducted using the VIS spectrophotometry method with Schiff reagent. The findings from the validation of the method indicated a detection threshold of 10.39 µg/mL and a quantitative limit of 34.65 µg/mL, with formalin recovery rates in anchovy samples between 98.8 and 101.16%. Qualitative examinations of six anchovy samples returned negative outcomes, and the quantitative analysis across all samples supported the findings, revealing that only one sample was free of formalin.

Abstract

Senggani is a traditional Asian plant commonly used as an alternative medicine, particularly in Indonesia. The leaves of the senggani plant contain secondary metabolites, including tannins, alkaloids, flavonoids, and saponins. Among these, tannins and flavonoids are believed to have antibacterial properties. This study investigates whether a facial wash gel made from the ethanol extract of senggani leaves possesses stable properties and meets established standards. Additionally, the study aims to evaluate its antibacterial activity against Cutibacterium acnes, the bacteria responsible for acne. A maceration method with 70% ethanol was used to prepare the ethanol extract from senggani leaves. This extract was then formulated into a facial wash gel using carbopol polymer at 5%, 7.5%, and 10%, followed by tests to assess its antibacterial activity. The antibacterial activity was determined using the disc diffusion method at the same concentrations. The results indicated that the diameter of the bacterial inhibition zone was 9.93 mm at 5%, 11.66 mm at 7.5%, and 13.93 mm at 10%. The gel preparation of the ethanol extract from senggani leaves demonstrated stable properties, with physical stability evaluations confirming compliance with the quality standards for facial washes set by Indonesian national regulations. Furthermore, the senggani leaf ethanol extract gel effectively inhibited the growth of Cutibacterium acnes, indicating its potential as an effective face wash.
