Abstract

Aktivitas keramba jaring apung (KJA) dapat mengakibatkan penurunan kualitas air. Tujuan penelitian ini adalah menentukan dampak aktivitas KJA di Waduk Lahor terhadap perubahan Kualitas air berdasarkan beberapa paremeter fisika kimia dan indeks biotik dari Diatom sebagai bioindikator. Pengambilan sampel air dan Diatom dilakukan di muara Sungai Lahor (3 stasiun) merupakan inlet dari Waduk Lahor dan daerah sekitar bendungan (1 stasiun) menggunakan purposive random sampling berdasarkan aktivitas KJA dengan pengulangan pada masing-masing stasiun tiga kali. Pengambilan sampel Diatom dengan water sampler vertikal dan disaring menggunakan plankton net. Identifikasi dan perhitungan Diatom dengan Counting Chamber Sedgewick Rafter Cell dan buku identifikasi. Hasil identifikasi dan penghitungan Diatom digunakan untuk menentukan Trophic Diatom Index (TDI) dan Pollution Tolerant Value (% PTV). Karakter fisika kimia air (pH, kecerahan, turbiditas, DO dan BOD) diukur pada lokasi yang sama dengan pengambilan sampel Diatom. Hasil penelitian menunjukkan bahwa kualitas air terutama parameter BOD dan kecerahan di Waduk Lahor belum memenuhi standar untuk aktivitas perikanan. Aktivitas KJA di muara Sungai Lahor berdasarkan beberapa indek biotik dari Diatom telah berdampak pada penurunan kualitas air yaitu status nutrisi menjadi eutrofik sampai hiper-eutrofik (TDI) dan tingkat pencemaran bahan organik ringan sampai sedang (% PTV).

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

The integrity of the water quality in the ecosystem must be maintained to provide benefits for the environment and the living creatures within it. The Singosari and Karangploso Districts have many springs which are usually used by the local community for various needs. Water quality can be evaluated using several types of bioindicators, and phytoplankton is one of the reliable bioindicators. This research aims to evaluate the water quality in Suceng, Nyolo, Sumberawan, Umbulan Ngenep, Nagan, Biru, Belik, Suko, and Umbulan Springs in Singosari using phytoplankton as a bioindicator. The research was conducted from June to September 2024. The physical and chemical parameters observed in the water were air temperature, water temperature, conductivity, total suspended solids (TSS), nitrate, orthophosphate, dissolved oxygen (DO), and biochemical oxygen demand (BOD). Determination of the phytoplankton community structure profile was carried out by calculating taxa richness/TR, IVI, H', dominance index/ID, %PTV, and TDI. The results showed that all physical and chemical quality parameters have met the Indonesian government’s Class II standards.  The phytoplankton H’ values range between 3.39 and 4.32, indicating the water is uncontaminated by toxic materials. However, based on %PTV, Belik Spring is considered heavily organic polluted water (%PTV 70), and Umbulan Ngenep is classified as moderately organic polluted water (39%). Based on TDI measurement, it can be concluded that Nyolo, Suceng, Sumberawan, Suko, and Umbulan Spring were considered as oligoeutrophic (TDI 12.0-25.0), while Nagan, Biru, Umbulan Ngenep, and Belik were classified as mesoeutrophic water (TDI 25.7-45.3). Therefore, it is essential to control the human activities around the springs in Karangploso and Singosari.

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.
