Abstract

Traditional gold mining activities in Tambang Sawah Village, Lebong Regency, Bengkulu Province, produce tailings waste with high concentrations of mercury (Hg). This waste is discharged directly into the Air Putih River without prior treatment. This research aims to measure mercury levels in the tailings and analyze the relationship between the quantity of discarded tailings and the Hg contamination levels in river sediments. Sampling was conducted following the JPHA method, and Hg level analysis was based on NOAA and ASTM guidelines. The results indicate that all tailings samples from 10 discharge points exceeded the mercury contamination threshold. The total estimated tailings discharged each week reached 1,600 kg from 40 miners. The highest concentrations were found at points with the most miners. A laboratory test on 10 tailing samples collected from discharge points along the Air Putih River showed that all samples contained mercury (Hg), with the highest concentration reaching up to 266 ppm.

Abstract

Telah dilakukan kegiatan PKM berupa penyuluhan dan pelatihan pembuatan sabun transparan. Kegiatan dilakukan di RW 019 Perumahan Villa Pamulang Pondok Benda Pamulang. Sabun merupakan kebutuhan pokok yang dibutuhkan untuk menjaga kebersihan dan kesehatan. Selama ini sabun diperoleh masyarakat dari membeli produk yang sudah ada dan merupakan bagian dari kebutuhan pokok mereka. Dengan semakin meningkatnya pengetahuan dan kesadaran masyarakat akan pentingnya menjaga kesehatan, kebutuhan akan sabun mandi dengan kondisi tertentu seperti herbal dengan berbagai manfaat tambahan dan juga tampilan yang transparan dan menarik makin dibutuhkan masyarakat.Pembuatan sabun ini cukup mudah dilakukan oleh masyarakat awam tanpa menggunakan peralatan khusus, namun diperlukan pengetahuan tentang sabun dan bahan lain terkait serta potensi bahaya yang dapat ditimbulkan. Pada pelatihan pkm ini diajarkan cara pembuatan sabun. Pelatihan dilakukan berupa penjelasan oleh dosen dan dilakukan praktek langsung oleh mahasiswa di depan para peserta. Pelatihan berlangsung lancar dan mendapat sambutan yang sangat baik dari masyarakat. Para peserta berharap agar kegiatan PKM dapat dilakukan secara berkesinambungan sehingga masyarakat dapat menerapkan pelatihan ini dalam pengembangan kewirausahaan dan dapat menunjang ekonomi masyarakat.

Abstract

Hypertension is a chronic medical condition characterized by elevated blood pressure levels exceeding the normal threshold (≥120/80 mmHg), which can lead to damage in vital organs such as the heart, kidneys, brain, and blood vessels. One promising alternative treatment involves the use of herbal remedies, such as celery leaves (Apium graveolens L), which are known to contain various vitamins, minerals, and antioxidant compounds including beta-carotene, lutein, zeaxanthin, and flavonoids such as luteolin and apigenin—both of which are recognized for their antihypertensive properties. This study aims to characterize the antioxidant activity and determine the flavonoid content of celery leaf extract using the maceration method. Extraction was conducted with varying ratios of solvent to leaf powder (1:10, 1:15, and 1:20) and different maceration durations (24, 36, and 48 hours). The best yield was obtained at a ratio of 1:15 with 24 hours of maceration, resulting in an extract with a pH of 6, density of 0.869 g/mL, and viscosity of 15.75 cP. Antioxidant activity analysis revealed an IC₅₀ value of 66.3774 mg/mL, while total flavonoid content reached 17.97 mg/g. These findings suggest that celery leaves possess potential as a natural antihypertensive agent due to their antioxidant activity and flavonoid content.Keywords: Hypertension, Celery Leaves, Antioxidants, Flavonoids and Maceration
