Abstract

The development of infrastructure could be one of a threat to habitat of horseshoe crabs. Regarding that, constructing of an international port at Kijing Beach in Mempawah could also become a menace to crabss habitat. Carcinoscorpius rotundicauda is known to be the most commonly found in Mempawah Mangrove Park (MMP) coastal area. This study aim is to analyze population structure and morphometry of Carsinoscorpius rotundicauda in MMP coastal area. Research was conducted on April-September 2022. Fishers collected horseshoe crab samples using trammel net. This study observed 14 characters and four ratios of morphometric, i.e. total length (TL), prosoma length (PL), opisthosoma length (OL), telson length, prosoma width (PW), carapace length (CL), compound eyes distance (CED), anal angle length (AAL), posterior angle distance (PAD), telson width (TW), median ridge length (MRL), anterior occeli length (AOL), process marginal length (PML), body weight, PL/OL, PW/PL, CL/TL, and CL/PW. The number of individuals of horseshoe crabs found high on September. The sex ratio of males to females was 1,95:1. The highest frequency relative of prosoma width was found in the range around 1214 cm (adult size). The ratio of PW/PL of female crab was significantly bigger than male. This difference could be used for determining sex of this species crabs. The growth pattern of mangrove horseshoe crabs bot males and females were negative allometry.

Abstract

River Continuum Concept (RCC) is an approach that describes the dynamic changes in the river system, the changes that occur are physical conditions (order of the river, canopy cover, and land use) and also the structure and function of communities. Functional feeding groups (FFG) of macroinvertebrates are related to environmental gradients in aquatic systems, including river ecosystem attributes. This study aimed to correlate the function of the macroinvertebrate communities with Cisadanes River headwater conditions based on RCC and also to estimate the attributes of the river ecosystem. This research was conducted in the headwaters of the Cisadane River, West Java-Indonesia. One of Cisadanes River headwaters was located in Mount Halimun-Salak National Park. Macroinvertebrates were collected from four sites inside the park (stations 1, 2, 3, and 4) and from two sites outside the park (stations 5 and 6). Collections were made twice a month, from April to June 2015 using a Surber sampler. The results showed that shredders and predators were relatively higher at stations inside the national park than at those outside the national park. While scrappers and collectors at stations located inside the national park were relatively lower than at stations outside the park. The value of the P/R ratio showed that all of the stations were heterotrophy. CPOM/FPOM ratio represents that shredder availability is high enough at stations inside the national park. While TFPOM/BFPOM ratio is slightly below the normal threshold value. HSI showed that the condition of the riverbed substrate stability is quite good. Composition changes of macroinvertebrates showed suitability with RCC. River ecosystem attributes and abiotic stream characteristics of Cisadanes River headwater support macroinvertebrate life and are in accordance with RCC.Keywords:EcologyMacroinvertebrateNational ParkRiparianRiver

Abstract

Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary. Plankton and water samples were taken for three months, with a frequency of one sample per month, viz. in March, April and June 2020 from four sampling stations in Kakap River Estuary, West Kalimantan. A total of 34 species of plankton were observed from all sampling sites, and identified to belong to 18 classes. Chlorophyceae had the highest relative abundance among the phytoplanktons (40.10%), followed by Bacillariophyceae (21.86%) and Cyanophyceae (19.28%). Oscillatoria sp. and Hydrodictyon sp. were the most dominant phytoplankton species. There were 8 classes of zooplankton identified from all sampling stations throughout the research period. Hexanauplia had the highest relative abundance among the zooplanktons (36.56%) followed by Euglenophyceae (24.37%). The plankton diversity index (H ) values ranged between 2.33 -3.11. The plankton evenness index value ranged from 0.79 to 0.89 which indicates high plankton evenness at all samping stations, and this is supported by a low dominance index value at all stations ranging from 0.06-0.16. Station 1 had high Shannon-Wienner diversity index score, while for station 2, 3, 4, their scores were in the moderate level. Overall. the diversity index of the plankton from all sampling sites indicated that the quality of the water had no pollution to light pollution level.Keywords:PhytoplanktonZooplanktonWater quality

Abstract

The degradation of seagrass meadows has prompted various efforts to restore the function and role of seagrass ecosystems in coastal areas. During two decades, various technical restoration development methods have been implemented to determine the effectiveness and efficiency of the techniques used. These methods can be adapted to the needs and conditions of the area to be restored, allowing for more flexibility in their use and implementation in the area. Lemukutan Island is a small island, approximately 45 minutes by motorized wooden boat from the main island. However, despite its relatively short distance, the island's primary economic activity is tourism, resulting in higher prices for some necessities. The 2024 DIPA PKM Agriculture Faculty program aims to introduce seagrass species, the role in the ecosystem, and implement the low-cost seagrass planting methods using the island's resources. The purpose of this community service activity is to encourage the community to participate actively in seagrass ecosystem restoration efforts.

Abstract

Plankton diversity serves as a biological indicator of water quality in aquaculture ponds. This study aimed to analyze the relationship between plankton diversity and water quality parameters in catfish, pangasius, and tilapia aquaculture ponds in Sambora Village, Mempawah Regency. The research was conducted over a three-month period (July-September 2025) using a field survey approach involving periodic plankton sampling and water quality measurements. The observed water quality parameters included temperature, water transparency, pH, nitrate, total phosphate, and biochemical oxygen demand (BOD), while plankton communities were assessed based on abundance, diversity, evenness, and dominance indices. The results revealed 22 phytoplankton genera representing seven phyla and four zooplankton taxa, with Anabaena sp. as the dominant phytoplankton taxon. Water quality varied among ponds, with the catfish and pangasius ponds generally characterized by lower pH and water transparency and higher nutrient concentrations than the tilapia pond, while relatively high BOD values were recorded across the three ponds. Correlation analysis indicated that pH was the only water quality parameter significantly associated with plankton diversity. These findings provide baseline information for the application of plankton as a bioindicator of water quality in traditional freshwater aquaculture ponds.

Abstract

Heavy metal contamination is an important environmental issue, particularly in developing countries where mining activities are widespread and environmental management is often limited. This study evaluated the level of heavy metal contamination in Lake Belibis, a post-mining pit lake formed by illegal artisanal gold mining activities in West Kalimantan, Indonesia, which is currently used as a natural tourism area. Water and sediment samples were collected from three purposively selected stations representing different surrounding land uses from May to August 2024. Concentrations of mercury (Hg), cadmium (Cd), copper (Cu), and lead (Pb) were analyzed using Atomic Absorption Spectrophotometry (AAS). In addition, supporting physico-chemical parameters were measured in situ. The results show that heavy metal concentrations in both water and sediment were generally below applicable environmental quality standards, indicating a relatively low level of contamination under current conditions. The physico-chemical characteristics of the lake reflect stable support the retention of heavy metals in particulate matter and sediments. Overall, the findings suggest that the environmental risk associated with heavy metals in Lake Belibis is currently low, but continuous monitoring is necessary to support environmental risk evaluation and sustainable management of the pit lake.
