Abstract

Rivers are surface water flows from upstream to downstream estuaries. The Umban Sari River is a tributary that flows into the Siak River. The activities along the river provide ecological pressure that continues to accumulate downstream. This study was conducted in March-May 2024 using macrobenthos as bioindicators of pollution. The purpose of this study was to determine the abundance, diversity, uniformity, dominance, biomass and ecological status of the Umban Sari River waters based on the ABC (Abundance and Biomass Comparison) macrobenthos curve method. This research uses a survey method by determining sampling stations using purposive sampling consisting of three stations. Macrozoobenthos sampling was carried out 3 times with an interval of once a month (30 Day interval). The results showed that the found 8 macrozoobenthic species consisting of Pila ampullacea, Pomacea canaliculate, Lymnaea rubiginosa, Bellamya sumatrensis, Gyraulus convexiusculus, Indoplanorbis exestus, Melanoides pantherine and Schistosoma sp. The highest abundance of macrozoobenthos was found at station I upstream of the river with an average of 3,685 ind/m2 and the lowest was found at station III downstream of the river with an average of 2,148 ind/m2. The diversity and uniformity of the macrozoobenthos is in the medium category, there are no species that dominate. The highest macrozoobenthic biomass was found at station I upstream of the river with an average of 2,643 gr/m2 and the lowest was found at station III downstream with an average of 2,199 gr/m2. The K-Dominant Hypothesis of the ABC curve in the Umban Sari River is included in the category and condition of an undisturbed and unpolluted ecosystem. However, the dominance of the relative biomass (BR) line was found to be only slightly above the relative abundance (KR) line and was close to overlapping, this indicates that the ecosystem condition is starting to become polluted.

Abstract

Penelitian ini bertujuan untuk mengetahui beban pencemaran dan status mutu air menggunakan metode indeks pencemaran di Sungai Umban Sari pada bulan Januari sampai dengan Maret 2024 dengan metode survey lapangan. Dalam pengambilan contoh air digunakan contoh air sesaat (grab sample) dimana pengambilan sampel sebanyak tiga kali selama kurun waktu tiga bulan di tiga stasiun penelitian. Penentuan beban pencemaran dilakukan perhitungan nilai beban aktual dan beban maksimum dengan parameter yang diukur yakni TSS, BOD, COD, Nitrat dan Total Fosfat. Status mutu air digunakan indeks pencemaran terdiri 9 parameter sesuai dengan Permen LHK No 27 tahun 2021 yakni pH, DO, BOD, COD, TSS, Total Fosfat, Nitrat dan Total Coliform. Beban pencemar dan status mutu air dengan indeks pencemaran akan dibandingkan dengan baku mutu kelas 2 PPRI No 22 tahun 2021. Hasil dari penelitian menunjukkan bahwa Sungai Umban Sari tidak lagi dapat menampung beban pencemaran BOD karena nilai beban aktual mencapai 2.914,95 kg/hari, sedangkan beban maksimum 903,31 kg/hari. Hasil analisis Status mutu air dengan nilai PI masing-masing sebesar 5,17, 5,51, dan 5,49 untuk stasiun 1, 2, dan 3, yang menunjukkan terjadinya penurunan kualitas air secara sistemik di seluruh penampang sungai yang diteliti.

Abstract

Mangrove ecosystems are characterized by the high diversity of associated biota found, such as sea scallops. Sea scallops are filter feeders and suspension feeders that live at the bottom of the waters by burying themselves in sediment. This study aims to determine the biological aspects of sea scallops (morphometrics, density, distribution, and growth) and ecological aspects (mangrove vegetation structure and knowing the condition of sediment fractions and organic matter) in Buruk Bakul Village, Bukit Batu District, Bengkalis Regency, Riau Province. Sampling was carried out on transects containing 9 plots measuring 1 x 1 m² with a depth of 30 cm and a distance between transects of 100 m. Sampling and observation were carried out 3 times with an interval of 2 weeks. The results showed that the morphometric size of sea scallops varied. The density value of lokan clams ranges from 150 ind/ha to 2,700 ind/ha, with the highest lokan density at station I, natural mangrove forest conditions, and no community activities. The distribution pattern of lokan clams is categorized as uniform with an average value of <1. The growth pattern of lokan clams shows a negative allometric pattern, namely b <3. The highest density of mangrove vegetation is at station I, with 1,522 trees/ha, in a good category. The highest sediment fraction is the mud fraction, ranging from 30.24% to 84.6%. The highest organic matter content is at station I with a value of 28.37%. The results of the study showed that the density, growth, and morphometrics of lokan clams in Buruk Bakul Village were significantly influenced by the ecological conditions of the mangrove forest, especially the density of mangrove vegetation, substrate composition, and concentration of organic matter in the sediment.

Abstract

Koto Panjang Reservoir is used as a fish farming site using the Floating Net Cage (KJA) system. The development of KJA in Koto Panjang Reservoir provides economic benefits for the community but also has the potential to cause a decline in water quality. This study aims to analyze the concentration of chlorophyll-a around the reservoir where KJA is located. The survey method was used for observations at 4 stations with 3 replications. The characteristics of the four stations were based on variations in the number of KJA plots: station 1 (60 plots), station 2 (no KJA), station 3 (350 plots), and station 4 (600 plots). Sampling was carried out in the morning from 08.00 to 12.00 WIB. Chlorophyll-a was analyzed using the spectrophotometric method. The concentration of chlorophyll-a in the waters of Koto Panjang Reservoir ranged from 7,693 to 12,927 µg/L, classified as mesotrophic. The highest value was detected at station 4 (12,927 μg/L) and the lowest at station 2 (7,693 μg/L). There was a tendency to increase chlorophyll-A concentrations in line with the increasing number of KJA plots. Water quality in the Koto Panjang Reservoir, based on pH, temperature, clarity, dissolved oxygen, free carbon dioxide, and chlorophyll-a, still supports the life of organisms.
