Abstract

This study aimed to identify mud crab species inhabiting the mangrove ecosystem of Batu Ampar, Kubu Raya Regency, West Kalimantan. Sampling was conducted from 26 October – 2 November 2024 during low tide using manual hand-catching, traditional traps (bubu), and fishermen’s catches obtained through interviews. A total of 20 crab individuals were collected and identified based on external morphological characteristics, referring to identification keys from WWF-Indonesia and the World Register of Marine Species (WoRMS). The results identified two dominant species, Scylla serrata and Scylla paramamosain. The main morphological differences included carapace coloration, claw size and shape, and the number and form of frontal spines. Among the total samples, S. serrata was more dominant compared to S. paramamosain. Interviews with fishers also revealed a body size classification commonly used in trade, namely Size A (≥ 600 g) and Size B (± 200 g), which directly influenced market prices. These findings confirm that the Batu Ampar mangrove ecosystem supports more than one economically valuable mud crab species. The study provides baseline information that can serve as an initial reference for sustainable management and conservation of mud crabs in coastal West Kalimantan

Abstract

Aquaculture of common carp (Cyprinus carpio) is a freshwater fishery commodity with high economic value and requires well-controlled water quality and fish health management. However, small- to medium-scale farmers still face limitations in continuous water quality monitoring. This community service activity aimed to improve the capacity of common carp farmers at Unit Pengolahan Air Dunia Air through training and mentoring on water quality and fish health management based on simple technology. The activity was conducted from September to October 2025 at Unit Pembenihan Rakyat Dunia Air, Koya Timur, Jayapura City. The methods employed included training sessions, discussions, hands-on practice mentoring, and the application of technology in the form of an Internet of Things (IoT)-based water quality monitoring device and a water quality control logbook. The IoT device was used to monitor water quality parameters in real time, while the logbook functioned as a tool for routine recording and evaluation. The results showed an increase in participants’ understanding of water quality management concepts, as indicated by their ability to identify key water quality parameters along with their optimal ranges. In addition, participants demonstrated improved skills in operating IoT-based monitoring devices and in routinely recording data in the water quality control logbook. Changes in aquaculture practices were also observed, including increased frequency of water quality monitoring and the implementation of fish disease prevention measures. The application of this technology promotes more controlled and sustainable common carp aquaculture practices.
