Abstract

This research aims to determine the water quality profile of Genjong River based on physicochemical parameters of water and benthic macroinvertebrates as bioindicators. Sampling was carried out at four different location based on difference of human activity in surrounding. The sampling was done in triple repetition for each station. The activity of station 1 is ecotourism (as reference site or positive control in this study), Station 2 (livestock I), Station 3 (livestock II), and Station 4 (plantation). The water physicochemical parameters were measured including water and air temperature, water current velocity and discharge, conductivity, pH, DO, BOD, TSS, nitrate, and orthophosphate. The result from the identification and calculation of the benthic macroinvertebrates density was used to determine some diversity indices and biotic indices. The difference in the value of each water quality parameter was tested by One-way ANOVA. Based on the abiotic water quality profile, Genjong River water is included as the Class IV category based on Indonesia Government Regulation No. 22 of 2021 with a BOD value of 3.61 – 7.22 mg.L-1. Human activities along the Genjong River have a great impact on decreasing water quality as indicated by increasing of nitrate levels from 0.52 ± 0.07 mg.L-1 at Station 1 up to 0.85 ± 0.07 mg.L-1 at Station 4. Also, orthophosphate levels from 0.02 ± 0.01 mg.L-1 at Station 1 to 0.18 ± 0.02 mg.L-1 at Station 4. Meanwhile, based on benthic macroinvertebrates as bioindicators, Genjong River was classified as lightly (S1, H = 1.74) to moderately polluted (S4, H = 1.24) with toxic materials and slightly contaminated with organic matter (S4 with FBI value = 5.38). The decline in water quality was also shown by the decreasing ASPT value from 4.20 at Station 1 to 3.68 at Station 4.

Abstract

The water quality in Awang Bay, West Nusa Tenggara, Indonesia, is considered to be polluted due to human activities. This research aims to evaluate the water quality in Teluk Awang based on the physicochemical properties of water and zooplankton as bioindicators. Sampling was conducted at three beach locations: Awang, Ujung Kelor, and Ekas. The physicochemical water quality parameters measured included water temperature, pH, dissolved oxygen (DO), salinity, and transparency. Additionally, environmental factors were observed based on the naturalness and hemeroby index. The result of the identification and counting of the abundance of each zooplankton can then be used to analyze including taxa richness, total density, the diversity index of Shannon-Wiener (HSW), Margalef diversity index, Simpson diversity index, evenness index (E), and dominance index (C). The resulting research indicated that the physicochemical water qualities have met government quality standards for marine biota needs, except for the level of transparency at Ekas Station 3. Ekas Beach has the highest level of transparency, diversity, taxa richness, and total abundance of zooplankton, indicating the best water quality. Ujung Kelor Beach, which has the highest level of naturalness and the highest DO concentration, has moderate zooplankton diversity, indicating that the water quality is in the medium category. Meanwhile, Awang Beach, which had the highest human activity and the worst water quality, was characterized by low levels of transparency and DO, low diversity, taxa richness, and an abundance of zooplankton. Therefore, diversity, taxa richness, and abundance of zooplankton can be used as a bioindicator for changes in water quality.

Abstract

Ngesong Spring is a clean spring that is used by society as a spring of clean water and as a tourist attraction. The Ngesong spring has a ditch that flows to the society settlement, where the water is used for agricultural and plantation irrigation. The utilization of the Ngesong Spring as a tourist attraction and its ditch through agriculture, settlements, and society settlements has great potential to cause pollution and degradation of water quality, so it is necessary to evaluate water quality. Therefore, it is necessary to monitor the quality of this water, one of which is the use of the macrozoobenthic community structure as a bioindicator. The research was conducted in four locations, namely, a water spring and the channels that will be used for agriculture, plantations, and settlement activities, in September and October 2022. The variables observed in this study included the physicochemical quality of the water, namely, the water temperature, conductivity, power of hydrogen (pH), dissolved oxygen (DO), biological oxygen demand (BOD), and total suspended solids (TSS), as well as the community structure and macrozoobenthos diversity. The results of this study indicate that 26 macrozoobenthic families belong to 12 orders, for a total of 968 individuals. Water springs had the highest diversity and evenness index values, with H = 2.27 and E = 0.54. The analysis of macrozoobenthic family relationships as an indicator of water quality using the family biotic index (FBI) and average score per taxon (ASPT) showed that the watershed site has very clean water and no organic pollution. At watersheds with good water quality, the families Perlidae, Nemouridae, Limnephilidae, Viviparidae, Chironomidae, and Euphaeidae were found. Moreover, In this study, the locations that have highly organically polluted waters are ditches that have agricultural activities and settlement activities.

Abstract

Phytoplankton are primary biotic components of aquatic ecosystems that are highly sensitive to environmental changes and are therefore widely used as biological indicators of water quality. However, information on phytoplankton community structure in waterfall ecosystems remains limited, particularly in tropical regions. This study aimed to analyze the phytoplankton community structure in waterfall ecosystems in Jabung district as a basis for assessing water quality. Sampling was conducted at four waterfall sites, namely Siuk, Tarzan, Toris, and Jahe, with three replicates at each location. Phytoplankton samples were collected by filtering 3 liters of water using a plankton net with a mesh size of 40 µm, then preserved with 4% formalin (10 drops) and CuSO₄ (5 drops). Identification and enumeration of phytoplankton were performed using 1 mL of sample placed in a Sedgewick–Rafter Counting Chamber and observed under a binocular microscope (100× magnification) across 1,000 fields of view. The collected data were used to calculate abundance, taxonomic richness, community composition, the Shannon–Wiener diversity index (H’), evenness index (E), and dominance index (D). The results showed that phytoplankton taxa were present in all observed waterfall ecosystems, consisting of Bacillariophyceae (21 genera), Chlorophyceae (9 genera), Cyanophyceae (5 genera), Zygnematophyceae (9 genera), and Trebouxiophyceae (1 genus). The highest diversity index was recorded at Jahe Waterfall (H’ = 4.50), while the lowest was found at Siuk Waterfall (H’ = 4.17). The highest evenness index occurred at Siuk Waterfall (E = 0.8773), with a dominance index value of 0.075. Overall, all sites exhibited high diversity (H’ > 3) and very low dominance, indicating that phytoplankton communities were stable and well balanced across all investigated waterfall ecosystems.  Keywords: Water Quality, Phytoplankton, Community, Waterfalls, Diversity
