The Nilem fish (Osteochilus hasselti), an indigenous freshwater species in Indonesia, has experienced a significant population decline due to various factors including habitat degradation from land conversion, water pollution, and overfishing. This decline threatens the stability of local aquatic ecosystems and biodiversity. To address this critical issue, a Restocking program was implemented in Negarajati Village, Cilacap Regency, specifically targeting the restoration of the Nilem fish population and the improvement of damaged aquatic ecosystems. The program adopted an integrated approach emphasizing active community involvement, particularly through the empowerment of Community Supervisory Groups (POKMAKWAS). Training provided to POKMAKWAS encompassed crucial aspects such as Nilem fish restocking techniques, water quality monitoring, sustainable natural resource management, waste management, and eco-friendly aquaculture. The methodology included local breeding and seed procurement (16,000 Nilem fish measuring 8-9 cm were stocked), periodic stocking at appropriate times and locations, continuous environmental supervision and monitoring, and robust community engagement. Academics from the Faculty of Fisheries and Marine Sciences, Universitas Jenderal Soedirman (FPIK UNSOED), facilitated and provided technical and scientific knowledge. The Restocking initiative aims to ensure the optimal growth and development of the stocked fish, fulfilling local fish resource needs, and supporting regional food security. The empowerment of POKMAKWAS is crucial as it fosters community understanding of endemic fish conservation rules and ecosystem sustainability, enabling them to act as effective supervisory agents against habitat destruction. This program is expected to become a routine, sustainable activity for POKMAKWAS, with continuous monitoring and evaluation by the local Fisheries Department and government support. The success of this program could lead to the expansion of stocking points and significantly increase community awareness regarding the importance of managing endemic fish and aquatic ecosystems sustainably. This collaborative effort between the community, government, and academia holds potential for positive economic impacts on local fishermen and serves as a model for endemic fish conservation in other regions.

The anaerobic ammonium oxidation (Anammox) process is a biological mechanism that converts ammonium and nitrite into nitrogen gas without the need for oxygen, making it a potentially efficient solution for nitrogen waste treatment. This study aims to analyze the effectiveness of Anammox in reducing nitrogen concentrations from various types of waste and compare it with conventional methods. This study was conducted using a systematic literature review approach on the effectiveness of the Anammox process in nitrogen removal from wastewater. The analysis was carried out by extracting information related to reactor types, operational parameters (pH, temperature, C/N ratio, and substrate concentration), nitrogen removal efficiency, and inhibitory factors. The results show that this process can consistently reduce ammonium and nitrite, with performance highly influenced by operational conditions. Factors such as microbial stability, temperature, and nitrite availability are the main determinants of success. This study confirms that Anammox offers a more energy-efficient approach, producing less sludge and being more environmentally friendly compared to nitrification–denitrification. Thus, Anammox technology contributes to the development of sustainable wastewater treatment systems while expanding scientific understanding of the role of Anammox bacteria in the nitrogen cycle.

Aquatic animals play a significant role in bioremediation processes in aquatic environments through their natural activities, such as filtering particles, aerating water, and nutrient cycling. This study aims to review the use of aquatic animals as natural biofilters in aquaculture systems, highlighting their efficiency and the supporting role of microbial technology. The method used is a literature review from 24 relevant articles published between 2015 and 2024. Results show that species such as goldfish, catfish, and eels can reduce organic waste, regulate plankton composition, and enhance oxygen levels. Moreover, the integration of probiotics and biotechnologies such as microbial fuel cells, bioaugmentation, and biostimulation improves pollutant degradation and water quality. The implications of these findings suggest that aquatic animal-based bioremediation is a promising and environmentally friendly approach to sustainable aquaculture, reducing reliance on antibiotics and chemical disinfectants while supporting ecological balance and animal health.

Regional food security is largely determined by the sustainability of fisheries production, one of which is through the minapadi system that integrates fish and rice cultivation. The main obstacle that often arises is suboptimal water quality management, which reduces fish productivity and aquatic ecosystem health. This community service activity aims to enhance the capacity of the Krido Yuwono Minapadi Technopark Panembangan Fish Farmers Group (POKDAKAN) in fisheries water quality management to support food security in Banyumas Regency. The assistance method was carried out participatively through socialisation and training on water quality management theory, field practice in measuring physical-chemical parameters (pH, dissolved oxygen and temperature), installation of simple monitoring devices, and evaluation of competency improvement through pre-tests and post-tests. The results of the activity showed an average increase in participants' knowledge from 47% to 76%, the implementation of a routine water quality monitoring schedule, and improvements in key parameters, including pH stability and real-time knowledge of water quality conditions. These findings confirm that participation-based assistance is effective in improving the technical skills of farmers, maintaining the quality of aquaculture water, and supporting the sustainability of the minapadi system as a strategy for strengthening regional food security.
