Abstract

Diatoms or phytobenthic are often used as bio-indicators of water quality in freshwater ecosystems such as rivers, but have never been used for monitoring the quality of artificial water ecosystems. The objective of this research is to use the diatom as a bioindicator for measurement the success of phytoremediation process of irrigation water that has status hyper-eutrophic and is polluted from organic materials using polyculture of various local hydromacrophytes through batch culture system. This experimental study was conducted in a greenhouse through planting some local emergent, submerged and floating leaf hydromacrophytes on a 30 L bucket with a given substrate from sand and gravel. The experiment used a completely randomized design with two treatment included phytoremediation model and control in the form of substrate without hydromacrophyte which repeated three times at the same time. The success of phytoremediation model was determined through some biotic diatoms indices (Percentage Pollution Tolerant Value/%PTV, Tropical Diatom Index/TDI and Shannon Wiener Diversity Index) as bioindicator and the improved water physics chemical quality on days 0, six, and 13 after incubation. The results showed that phytoremediation process using polyculture hydromacrophytes through batch culture system for 13 days significantly improving the quality of irrigation water. Based on some biotic diatom indices, the water was improved from heavily organic pollution to moderately organic pollution (%PTV), from hypereutrophic to become eutrophic (TDI) and from moderately polluted become slightly polluted (Shannon Wiener Diversity Index). This results also supported from water physico-chemical parameters. Poly-culture of some local hydromacrophytes for six days significantly decreased the organic matter content of irrigation water was reflected from the decrease concentration of Biochemical Oxygen Demand/BOD (14.79 mg/L to 3.61 mg/L), Total Suspended Solid/TSS (14.6 mg/L to 0.08 mg/L), turbidity (19.97 NTU to 1.46 NTU), nitrate (1.44 mg/L to 0.03 mg/L), orthophosphate (0.24 mg/L to 0.042 mg/L), Total Kjeldahl Nitrogen (TKN) (0.93 mg/L to 0.68 mg/L), and free chlorine (0.09 mg/L to 0.05 mg/L), while concentration of Chemical Oxygen Demand (COD) decreased significantly 13 days after incubation from 48.3 mg/L to18.2 mg/L.

Abstract

The quality of water in Spermonde Archipelago, South Sulawesi has decreased as a result of high human activities and land use, this can have an impact on the life of marine biota. Macroalgae is suitable for bioindicators because they live in a sessile manner, can accumulate metals and distributed widely. This research aimed to determine coastal ecosystem quality by using macroalgae as indicators on five islands that had different anthropogenic stresses. The research was carried out in April 2019 on Barrang Caddi, Bonebatang, Barrang Lompo, Kodingareng Keke, and Badi Islands. Community structures observed included taxa richness, diversity, evenness, dominance of macroalgae and physicochemical parameters (temperature, turbidity, pH, salinity, DO, BOD, H2S, oil, grease, total Phosphate, and nitrate) as well as the measurement of the ecological condition using Quality of Rocky Bottoms (CFR) index. The results showed that physicochemical parameters (temperature, turbidity, pH, salinity, DO, H2S, oil, grease, total Phosphate) of the water still met the quality standards of sea water based on Decree of the State Minister for Environment No. 51/2004 for marine biota and other standards for macroalgae growth. BOD and nitrate have exceeded sea water quality standards for marine biota (20 mg/L for BOD and 0.008 mg/L for nitrates). A total of nine species of macroalgae were found in Barrang Caddi and Badi Island, three species in Bonebatang, and five species in Kodingareng Keke and Barrang Lompo Island. The result of Principal Component Analysis (PCA) and Biplot showed that physicochemical water quality has an influence on the macroalgae community structure. While the CFR index shows Barrang Caddi and Badi Island have poor ecological conditions and Bonebatang, Barrang Lompo, and Kodingareng Keke have bad ecological condition.

Abstract

Riparian vegetation habitats in irrigation canals provide various ecosystem regulatory services for human life. One of them was providing a habitat of natural enemies for agricultural pests. This research aims to evaluate the community structure of natural enemies based on the diversity index and abundance value, and riparian vegetation community in the four different categories of tertiary irrigation canals at the Slamet Village rice field. Arthropods were observed using a visual encounter survey and yellow pan trap methods for fifteen days. At the same time, riparian vegetation analysis was also applied by purposive sampling. The results showed that the first location of irrigation canals had the highest Shannon-Wiener diversity index, taxa richness, evenness, and the lowest dominance value of riparian vegetation with respectively 4.97; 37 species; 0.93; and 0.02. Moreover, it was followed by high natural enemy’s taxa richness based on yellow pan trap and visual encounter survey (16 and 28 families), total abundance (554 and 4450 individuals), diversity index (1.83 and 3.67), evenness index (0.77 and 0.68), and low dominance index (0.22 and 0.21). Arthropods that act as natural enemies commonly found in this location came from the Formicidae, Coenagrionidae, and Coccinelidae families, while the most common pests found were from the Acrididae family. The opposite of that, the fourth location had a high dominance index of riparian vegetation (0.15), diversity index of pest (1.83), taxa richness of pest (10 families), and 272 individuals of pest arthropod arthropods. The highest abundance of pests in this location came from the Acrididae, Drosophilidae, Tephritidae, and Aphididae families.

Abstract

Highlight Research Anthropogenic factors are the main cause of damage to mangrove ecosystems Restoration is a method for ecosystem restoration Restoration success is seen from the physical, chemical, and biological parameters Phytoplankton is a bioindicator of water quality The abundance of mangroves can explain the state of an ecosystem   Abstract Mangrove ecosystems in Sine and Pancer Cengkrong had degraded due to land-use change and restoration has been carried out over a few year on the damaged location. This study was conducted to evaluate water quality of mangrove ecosystems at both locations based on physical, chemical and phytoplankton parameters as bioindicators. The evaluation of Cengkrong Mangrove was carried out at 4 different locations based on different periode of restoration, namely restoration of 2008-2009, 2013-2014, natural mangroves, and 2005 succession mangroves, whereas there was only one sampling site at Sine mangrove namely 1998-2008 restoration. The physico-chemical parameters measured include water temperature, air temperature, conductivity, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), salinity, nitrate, and orthophosphate. Phytoplankton data was used to measure, trophic diatom index (TDI) as an indicator of water nutrition status, and pollution tolerant value (%PTV) as an indicator of organic pollution. The results showed that the water quality at all the study locations met the Indonesian Ministry of Environment Regulation No 51/2004, except nitrate and phosphate. Based on the TDI index, mangrove in Sine, Cengkrong 2013-2014 restoration, and 2005 succession mangroves were categorized as hyper-eutrophic, natural Cengkrong mangroves were categorized as eutrophic, and 2008-2009 restored Cengkrong mangroves were categorized as meso-eutrophic. Based on the %PTV index, in the Sine mangrove, 2013-2014 Cengkrong restoration, and 2005 succession mangroves were classified as high levels of organic matter pollution, while in the Cengkrong 2008-2009 restoration and natural Cengkrong were classified as a moderate level of organic pollution.

Abstract

The riparian zone along the Tamiang River, Aceh Province, is an important habitat for the survival of the tuntong laut (Batagur borneoensis) which is already threatened with extinction. This study aims to evaluate the quality and role of the riparian zone as a habitat for B. borneoensis along the Tamiang River, which can then be used as a reference in conservation. Riparian habitat quality was assessed by calculating the Qualitat del Bosc de Ribera (QBR) index, which was determined based on the total riparian cover, cover structure, cover quality, and channel alteration. In addition, observations of water quality (salinity, turbidity, and dissolved oxygen (DO)) and the number of riparian vegetation species were also carried out. Monitoring was carried out at five stations: Iyu River, Kampung Baru, Batang Lawang, Pusong Kapal Dermaga, and Pusong Kapal. The results showed variations in water quality between locations with DO and turbidity levels exceeding the quality standards set by the government. The richness of the types of riparian vegetation found ranged from 0-8 species (seedlings), 2-7 species (saplings), and 1-4 species (poles). The quality of riparian habitats in all study locations experienced significant degradation, including the euhemerobic and polyhemerobic (Hemeroby) categories, Cultural assisted system and Semi-transformed system (Naturalness), and Extreme degradation to poor-fair quality (QBR). The presence of B. borneoensis in the research location can adapt to the poor quality of riparian habitat. However, the density decreases significantly at higher salinity.

Abstract

The study proposed identifying the changes in bacterial community and diversity and exploring the potential correlations among sediments parameters and benthic bacterial communities under different mangrove ecosystems rehabilitation statuses. There were three sites: 1. Banyuurip Mangrove Center (BMC) as a restoration site; 2. Pulau Lusi (PL) as a degraded site; and 3. Kampung Blekok (KB) as natural site. The physicochemical parameters and benthic bacteria from the mangrove sediment of the three locations were observed. The data were analyzed statistically to determine the sites' variation and the correlation between parameters. The results found that the physicochemical parameters among restoration sites varied. Soil organic matter (SOM) in natural and restoration sites was significantly higher than in degraded sites. Cation exchange capacity (CEC), calcium and potassium ions, and soil conductivity of the restoration site were considerably higher than the other sites. According to diversity indices and taxa richness, benthic bacteria in the restoration were the most diverse. Proteobacteria dominated in natural and restoration sites; meanwhile, Firmicutes dominated in degraded site. Sulfurovum aggregans was found abundant in natural and restoration sites; meanwhile, Mesobacillus subterraneus was the dominant species in the degraded site. Furthermore, the bacterial taxa richness was positively correlated with SOM and the bacterial diversity was correlated with CEC and conductivity.

Abstract

Brantas River is the largest river in East Java, flowing from the city of Batu upstream until downstream in Surabaya and Sidoarjo. This river plays a crucial role as a vital natural resource that supports the various needs of the surrounding communities. This study serves as a preliminary investigation with the primary aim of assessing the water quality in three different zones of the Brantas River: the upper, middle, and downstream sites. Additionally, this research includes a review to identify the organisms exposed to water pollution in the Brantas River. The study was conducted from November 2020 to April 2023, utilizing an exploratory observational method at 19 observation stations. The data obtained was subsequently analyzed using a descriptive approach. Various parameters were observed, including pH (a measure of acidity or alkalinity), hardness (the concentration of calcium and magnesium ions), alkalinity (the capacity of water to neutralize acids), nitrate, nitrite, fluoride, and heavy metals such as lead (Pb), copper (Cu), and iron (Fe). The research findings indicate that in several upstream areas of the Brantas River, there were elevated hardness, nitrate, lead (Pb), and iron (Fe) that exceeded the established water quality standards. In the middle section of the river, water quality was generally satisfactory, although a few locations exhibited slightly elevated levels of lead (Pb). Meanwhile, all locations downstream of the Brantas River demonstrated water quality that exceeded the prescribed standards. After a literature review, it was discovered that various biota in the Brantas River have been exposed to pollutants, including fish species and plants like Ipomea aquatica and Eichhornia crassipes. Therefore, it is necessary and urgent to improve water management and monitoring plants and biota in the Brantas River to preserve organisms in aquatic and terrestrial ecosystems.

Abstract

The aquatic ecosystem in the Menala River has been degraded due to anthropogenic activities. The purpose of this study was to evaluate the water quality in the Menala River based on water physicochemical and benthic macroinvertebrates as bioindicators. Water quality was evaluated at seven stations based on anthropogenic activities in the surrounding. The physicochemical parameters measured included water temperature, turbidity, electrical conductivity, pH, DO, TDS, BOD, nitrate, and total phosphate. Benthic macroinvertebrate data were used to determine the importance value index (IVI), Shannon-Wiener diversity index (H'), evenness index (E), Simpson dominance index (C), the average score per taxon index (ASPT), and family biotic index (FBI). The data were analyzed by one-way ANOVA, biplot, and correlation test using PCA. The research result indicated that the concentration of DO (5.97 – 11.7 mg.L-1) at each station only fulfilled in class 3 of water quality, BOD (2.83 – 4.03 mg.L-1) in class 2, and Total phosphate (0.03 – 0.23 mg.L-1) only meets class 3. Based on the H', FBI, and ASPT index, the first station was categorized as clean water, the second to fourth stations were categorized as good to fairly poor, and the fifth to seventh stations were categorized as lightly polluted to probable severe pollution. Keywords: Benthic Macroinvertebrates, Menala River, physicochemical parameters, water quality.

Abstract

The irrigation water quality in Plosowahyu village, Lamongan District, Indonesia, has declined because of industrial waste disposal in irrigation canals. Specifically, waste from a metal-coating factory considerably threatens the aquatic ecosystem. To assess the impact, we evaluated water quality on the basis of phytoplankton diversity and various phys-icochemical parameters. We collected water and phytoplankton samples from four locations in Plosowahyu village: before the wastewater treatment plant (WWTP) outlet of the metal-coating factory, at this outlet, and from two sites in Wahyu River, with three repetitions at each site. The study measured several physicochemical parameters, including total dissolved solids (TDS), total suspended solids, conductivity, temperature, pH, salinity, dissolved oxygen (DO), bio-logical oxygen demand (BOD), chemical oxygen demand (COD), nitrate, orthophosphate, bicarbonate, total organic matter, sodium adsorption ratio, and lead (Pb) concentration. Phytoplankton diversity, indicated by the Shannon–Wiener index, suggested that water quality was moderately polluted at the locations before and at the WWTP outlet, lightly polluted at Wahyu River 2, and clean at Wahyu River 1. Physicochemical tests revealed that irrigation water quality parameters were below Indonesian government standards at several locations: TDS at the WWTP outlet of the metal-coating factory, DO at Wahyu River 1 and Wahyu River 2, and COD at the WWTP outlet and both Wahyu Riv-er locations. BOD, nitrate, bicarbonate, and Pb concentrations were below standards at all study sites. Principal compo-nent analysis confirmed that the metal-coating factory considerably degrades water quality. A comprehensive irriga-tion water management plan must be implemented to protect and improve irrigation water quality in Plosowahyu vil-lage.
