Abstract

Kota Pekalongan adalah daerah industri batik yang limbahnya mengandung logam berat berakibat tercemarnya perairan. Pencemaran dapat mempengaruhi kualitas air serta diserap oleh biota perairan sehingga membuat hasil tangkapan ikan tercemar, sehingga jika dikonsumsi oleh manusia menyebabkan toksisitas. Logam kadmium (Cd) dan Timbal (Pb) bersifat karsinogenik, memberikan efek genotoksik, sitotoksik, kerusakan pada paru-paru, ginjal, hati, sistem saraf dan darah. Tujuan dari penelitian ini adalah mengetahui kandungan kadar logam berat kadmium (Cd) dan timbal (Pb) pada ikan kakap putih, ikan kerapu dan ikan tigawaja di Perairan Kota Pekalongan. Metode dalam penelitian ini dilakukan secara kuantitatif dengan menggunakan instrumen AAS (Atomic Absorption Spectrophotometry). Hasil penelitian menunjukkan bahwa kadar kadmium (Cd) dalam ikan kakap putih sebesar 0,17 mg/Kg, ikan kerapu sebesar 0,22 mg/Kg dan ikan tigawaja sebesar 0,19 mg/Kg. Kandungan kadar timbal (Pb) pada ikan kakap putih, ikan kerapu dan ikan tigawaja secara berurutan sebesar 1,64 mg/Kg, 2,63 mg/Kg dan 1,35 mg/Kg. Ketiga sampel kadar kadmiumnya melebihi batas ambang yang ditetapkan oleh BPOM No. 5 Tahun 2018 sebesar 0,10 mg/Kg. Kadar timbal dalam ketiga sampel melebihi batas ambang yang ditetapkan oleh BPOM No. 9 Tahun 2022 sebesar 0,3 mg/Kg.

Abstract

One of the common male sexual disorders is low libido (sexual desire). An alternative approach to overcome this problem is the use of aphrodisiacs, substances that stimulate and enhance sexual desire. Coriander (Coriandrum sativum L.) contains flavonoids, alkaloids, saponins, and terpenoids, which may improve blood circulation and potentially enhance sexual activity. This study aimed to evaluate the aphrodisiac activity of ethanolic extract of coriander herb (EHC) on the libido of male Wistar rats (Rattus norvegicus). The extract was obtained using the maceration method, while the aphrodisiac test was conducted on 25 male and 25 female rats aged 2–2.5 months with body weight ranging from 150–200 g. The animals were divided into five groups, each consisting of 5 males and 5 females: negative control (1% Na CMC), positive control (sildenafil 50 mg), and three treatment groups receiving EHC at doses of 400 mg/kgBW, 600 mg/kgBW, and 800 mg/kgBW. For five consecutive days (6:00 p.m.–7:00 a.m.), one male and one female were placed in the same cage, and sexual activities of male rats (introducing and mounting) were observed using CCTV recordings. The results showed that EHC exhibited aphrodisiac activity at a dose of 800 mg/kgBW, which was not significantly different from the positive control (sildenafil 50 mg) (p=0.571). Statistical analysis using One-Way ANOVA indicated a significant difference among groups (p<0.05), and Tukey’s post-hoc test confirmed significant differences among all EHC dose groups (p<0.05). In conclusion, the ethanolic extract of coriander herb demonstrates potential as an aphrodisiac to enhance libido in male Wistar rats.

Abstract

Water spinach (Ipomoea aquatica Forssk.) is a vegetable that is widely found and consumed by the public, containing among others protein, calcium, phosphorus, iron, potassium, zinc and vitamins A, B1 and C. Zn is a micronutrient that functions for growth and development of bone metabolism. Fe is a micromineral for the formation of hemoglobin in the blood. The purpose of this study was to determine the content and amount of zinc and iron in water spinach based on different growing places using the AAS (Atomic Absorption Spectrophotometry) method. The sample used in this study was water spinach (Ipomoea aquatica Forssk.) taken from 3 locations, namely Sapugarut, Coprayan and Kandang Panjang. The method in this study was qualitatively using color testing and quantitatively using AAS. The results of qualitative testing on Fe produced a brownish color and Zn produced a clear solution with a white precipitate. Quantitative test results using the AAS method at a wavelength of 248.3 nm for zinc and 213.9 nm for iron. The Zn content in the sample obtained was sample A of 0.3869 mg/100 g, sample B of 0.5199 mg/100 g and sample C of 0.2556 mg/100 g while the level of Fe in sample A was 2.502 mg/100 g, sample B was 2.275 mg/100 g and sample C was 1.925 mg/100 g. The results of the study showed that the Zn and Fe levels had different levels, this was because the nutrient content in the soil had different nutrients.

Abstract

Euphorbia tirucalli L. (patah tulang) contains secondary metabolites with potential anti-inflammatory activity. This study aimed to identify its bioactive compounds and evaluate erythrocyte membrane stabilization of the extract and fractions. Extraction was performed by maceration with 96% ethanol, followed by fractionation using chloroform, ethyl acetate, and methanol. Total flavonoid and phenolic contents were measured by UV-Vis spectrophotometry, while erythrocyte membrane stabilization was tested in vitro. Phytochemical screening revealed flavonoids, phenols, saponins, steroids, triterpenoids, and tannins. The phenolic content was 432.1 ± 99.4 mg/g in the extract, 1,057 ± 88.02 mg/g in the chloroform fraction, 254.4 ± 48.84 mg/g in the ethyl acetate fraction, and 643.2 ± 267.3 mg/g in the methanol fraction. The highest flavonoid content was found in the chloroform fraction (4.26 ± 0.12 mg/g), followed by the extract (3.63 ± 0.35 mg/g), ethyl acetate (3.56 ± 0.36 mg/g), and methanol (2.6 ± 0.03 mg/g). Membrane stabilization assays showed the extract provided the strongest protection (95.04%), followed by chloroform (89.51%), ethyl acetate (87.71%), and methanol (87.52%), approaching the positive control diclofenac sodium (90.59%). Kruskal-Wallis and Tukey tests indicated the ethanol extract at 100 μg/mL (p=0.997 >0.001) and chloroform fraction at 500 μg/mL (p=0.023 >0.001) were not significantly different from the control, while ethyl acetate and methanol fractions differed significantly (p<0.001). These results demonstrate that the ethanol extract and chloroform fraction possess the highest anti-inflammatory potential, supported by high phenolic and flavonoid levels and consistent statistical analysis.
