Abstract

Freshwater ecosystems located near urban, industrial, and residential areas are vulnerable to heavy metal contamination derived from anthropogenic activities, including industrial discharge, domestic wastewater, and surface runoff. These contaminants may accumulate in aquatic organisms and potentially affect food safety when contaminated fish are consumed. This study evaluated the concentrations of iron (Fe), copper (Cu), and manganese (Mn) in the edible muscle tissue of Mozambique tilapia (Oreochromis mossambicus) collected from Situ Tlajung Hilir, Bogor Regency, Indonesia. Fish samples were obtained from three purposively selected locations representing areas influenced by community activities, industrial operations, and domestic wastewater discharge. Heavy metal concentrations were determined using Atomic Absorption Spectroscopy (AAS) following wet digestion of dried muscle tissues. The concentrations of Fe, Cu, and Mn varied among sampling locations, with Fe showing the highest accumulation, followed by Cu and Mn. Based on dry weight measurements, Fe concentrations ranged from 66.14 to 621.39 mg kg⁻¹, Cu from 0.87 to 21.27 mg kg⁻¹, and Mn from 5.14 to 6.18 mg kg⁻¹. Although numerical differences were observed among sampling locations, statistical analysis indicated that these differences were not significant, suggesting high within-site variability and limited statistical power due to the small number of biological replicates. The elevated concentrations of metals in fish muscle indicate that O. mossambicus from Situ Tlajung Hilir has accumulated Fe, Cu, and Mn, possibly reflecting the influence of surrounding anthropogenic activities. However, direct identification of contamination sources requires further analysis of water, sediment, and physicochemical parameters. These findings provide preliminary evidence of heavy metal bioaccumulation in fish from an urban freshwater ecosystem and highlight the need for continuous environmental monitoring and future human health risk assessment.

Abstract

The purpose of the following community service activity is to educate KWT Sawargi members through counselling on the use of new varieties of taro plants Febi521 and its post-harvest processing for processed taro production houses, as well as preparing activity plans for implementing the use of new varieties of taro Febi521 and its post-harvest processing. The target group of this activity are the residents of the Women Farmers Group (KWT) Sawargi, Situ Gede Village, West Bogor District, Bogor City. This Community Service activity can be divided into three stages: preparation, implementation, and evaluation. The results of this activity have a positive impact on increasing knowledge and skills and have the potential to improve the economy of the community. KWT members have a new understanding of the new taro variety Febi521, which has the advantage of not itching due to low levels of calcium oxalate. KWT also knows the nutritional value of Febi521 taro. In addition, KWT members also understand Febi521's post-harvest processing techniques and skills in processing taro products in the form of cookies made from taro flour. Sustainability support of this activity, the team provided new varieties of taro seeds Febi521 and production tools for post-harvest processing of taro.Keywords: taro; Febi521, post-harvest, taro flour, cookiesAbstrakKegiatan pengabdian masyarakat bertujuan untuk edukasi kepada mitra KWT Sawargi melalui penyuluhan pemanfaatan tanaman talas varietas baru Febi521 dan pengolahan pascapanennya dan menyusun rencana aktivitas implementasi pemanfaatan tanaman talas varietas baru Febi521. Kegiatan pengabdian kepada masyarakat ini dibagi dalam tiga tahap yaitu, persiapan, pelaksanaan, dan evaluasi. Hasil kegiatan ini memberikan dampak positif terhadap peningkatan pengetahuan, keterampilan, dan berpotensi meningkatkan perekonomian masyarakat Kelurahan Situ Gede, Kecamatan Bogor Barat, Kota Bogor. Anggota KWT memiliki pemahaman yang baru tentang talas varietas baru Febi521 yang memiliki keunggulan tidak gatal karena rendahnya kadar kalsium oksalat. KWT juga memiliki pengetahuan tentang nilai gizi talas Febi521. Selain itu, para anggota KWT juga memahami teknik pengolahan pascapanen talas Febi521 serta memiliki keterampilan dalam mengolah produk olahan talas berupa cookies berbahan dasar tepung talas. Untuk mendukung keberlanjutan kegiatan ini, tim memberikan bibit talas varietas baru Febi521 dan alat produksi olahan talas pascapanen.Kata Kunci: talas, Febi521, pascapanen, tepung talas, cookies

Abstract

The Contents of Heavy Metals Lead (Pb), Cadmium (Cd), and Mercury (Hg) in the Spotted Barbs(Barbodes binotatus) bodies and Cikaniki River Water, Bogor Regency. The Cikaniki River has experienced a decrease in water quality caused by human activities, both extractive and non-extractive, which can potentially cause pollution. Such activities that can pose a pollution threat include Unlicensed Gold Mining (PETI) and the mining industry of PT Antam, which is located in the vicinity of the Cikaniki River. Heavy metal pollutants in the waters of the Cikaniki River consist of lead (Pb), cadmium (Cd), and mercury (Hg). Heavy metals that enter water bodies can also accumulate in fish bodies. This study aims to determine the heavy metal contents of lead, cadmium, and mercury in the water of the Cikaniki River and the bodies of Spotted Barbs (Barbodes binotatus) inhabiting the river. The samplings were carried out using the purposive sampling method at five stations representing upstream and downstream watersheds, gold industrial areas, illegal mining areas, and irrigation areas. The study was conducted for three months, from January to March 2020. Tests for heavy metal levels in the water and fish bodies were conducted using ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry). The results showed that the contents of heavy metals Pb and Hg in the water were still below the threshold values of the quality standard according to the Government Regulation of the Republic of Indonesia No. 22 of 2021 Appendix VI, while the Cd content in the Cikaniki River water was below 0.02 mg/L. The cadmium content in the fish was below 0.4 mg/kg, while the contents of mercury and lead in the fish have exceeded the threshold values of the 1989 WHO quality standard. The highest accumulation of heavy metals in the fish was found in gold mining areas. Pearson correlation analysis showed that the most influential environmental parameter on the contents of heavy metals in the water and fish bodies was the water temperature. The presence of heavy metals in the water and fish of the Cikaniki River should be monitored as they accumulate in the human bodies.
