“…There has been no research related to the content of heavy metals in water, sediment, and fish in the Cikanikiriver. The study results Azizah & Anen (2019), show that Cikaniki River watershed is polluted with light pollution levels. In 2004, Syawal &Yustiawati found that mercury (Hg) in the water had an average concentration of 35 times above the maximum limit set for Class III with a range of 0.0023 -0.1743 mg / L), up to 2019 not yet.…”

“…The levels will continue to increase if the waters continue to be polluted. Even though the Cikaniki River is categorized as lightly contaminated, its status maygrow if there is still pollution (Azizah & Anen, 2019). Under anoxic conditions, microbial activity can form arsenic in methylate, solid, and enter the atmosphere (Istarani & Pandebesie, 2014).…”

Organisms that live in waters are sensitive to changes in the water quality in which they live. The quality of the water in the Cikaniki River is threatened by the gold mining industry, illegal mining, agricultural activities, and settlements. One of the organisms that will be affected by these environmental changes is fish. This research aims to obtain a diversity index of fish species and to determine the content of heavy metals Mercury (Hg), Arsenic (As) on the water, and fish. Research on the diversity of fish in Cikaniki River, Bogor Regency, was carried out in January–March 2020. The research was conducted at five selected stations, and each station carried out three times the sampling of fish and water. The metal content test process is carried out at the Chemical Laboratory of the University of Nusa Bangsa. The research instrument used was the observation sheet for fish identification and heavy metal content. Fish identification was carried out at the Faculty of Mathematics and Natural Sciences Laboratory, University of Nusa Bangsa. Identification use characteristics observed included body shape, body length height, color pattern, muzzle shape, fin shape, number of fins, and tail shape. Calculation of heavy metals using an ICP–OES (Inductively Coupled Plasma) tool. This research found seven fish species in the Cikaniki river; based on its dominance, four types of fish dominate: Nemacheilus chrysolaimos, Puntius bionotatus, Channa striata, and Glyptothorax platypogonides. The content of heavy metal mercury (Hg) in water is still below the standard quality threshold, while the Hg content in fish is above the quality standard with a value range of 0.5 - 1.09 mg/kg. The content of heavy metal Arsenic (As) in water ranges from 0.02 - 0.6 mg/L, with the highest value found at stations 4 (irrigation canals), As in the highest fish at stations 1 and 2 with a value range of 1-1.1 mg/kg. The conclusion of this research is that there are seven species of fish and fish in the Cikaniki river which contain high Hg and As heavy metals.

Belawan river is one of the rivers in North Sumatera Province. Belawan river which crosses Deli Serdang District and Medan City is used for the activities of plantation, agriculture, livestock, sand mining, a place for bathing and washing as well as serving as a lavatory, hospital, hotel, settlements, and industry. Utilization of the river as a wastewater disposal site can cause a decrease in the quality of river water. The purpose of this research was to analyze the Belawan river water quality spatially. Water sampling was taken at nine points which included three upstream segment points in Deli Serdang District, three middle segment points in Deli Serdang District and Medan City, and three downstream segment points in Deli Serdang District. Based on the results of the research it can be concluded that the value of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) at several monitoring points in Belawan river has exceeded the water quality standard limits of class I Government Regulation of Republic of Indonesia Number 82 the year 2001 and North Sumatera Governor Regulation Number 21 the year 2006.
