Abstract

Nickel mining plays a strategic role in supporting the national economy, particularly for the metal and renewable energy industries. However, mining activities also generate significant environmental impacts, especially land degradation and the decline of aquatic resource quality due to increased sedimentation, alterations in the physical and chemical properties of soil and water, and the introduction of heavy metals into aquatic systems. These conditions directly disrupt aquatic ecosystems and reduce biodiversity. This article aims to review rehabilitation and conservation strategies for aquatic resources in post-nickel mining areas through a literature review approach. The study employed a descriptive qualitative method by analyzing relevant national and international scientific publications focusing on land reclamation, revegetation, water quality management, and post-mining aquatic ecosystem restoration. The review results indicate that effective rehabilitation of aquatic resources requires an integrated approach, including land reclamation to stabilize soil conditions, revegetation using adaptive plant species to improve soil fertility and control erosion, and water quality management through sedimentation ponds, constructed wetlands, and riparian vegetation. The implementation of these strategies has been shown to reduce sediment and heavy metal loads, improve water quality, and support the recovery of aquatic ecological functions. Furthermore, community involvement and sustainable management practices are essential to ensure long-term rehabilitation success. With well-planned and sustainable rehabilitation efforts, post-nickel mining areas have the potential to be restored into healthy and productive aquatic ecosystems that provide ecological as well as socio-economic benefits for surrounding communities

Abstract

Urban activities are one of the main factors that put significant pressure on river ecosystems through the disposal of domestic waste, industrial waste, and surface runoff that carry various types of pollutants, along with population growth, increased economic activity, and uncontrolled land-use changes. These conditions have an impact on the decline in water quality which is characterized by an increase in the load of organic matter, nutrients, and harmful substances, thereby triggering the degradation of river habitats in the form of excessive sedimentation, damage to riparian vegetation, and changes in the physical structure of river channels, which ultimately lead to a decrease in aquatic biodiversity, both in terms of number and species composition. Many aquatic organisms, such as fish and macrozoobentos, are becoming increasingly vulnerable to pollution and habitat loss, resulting in population declines and even local extinctions. Based on these conditions, this article aims to examine the concept of conservation and rehabilitation of river aquatic resources affected by urban waste through a national literature review approach. The method used is a literature study of Indonesian scientific journals, reference books, and official government documents related to environmental and water resources management. The results of the study show that urban river conservation and rehabilitation efforts require an integrated approach that includes pollution control through effective waste management, restoration of river and riparian habitats, and sustainable management of watersheds, supported by strong environmental policies, consistent law enforcement, and active community participation to ensure the sustainability of the ecological function of rivers

Abstract

Vibrio harveyi is a Gram-negative marine bacterium from the genus Vibrio known for its ability to emit light (bioluminescence). This bacterium is rod-shaped, moves using flagella at one end, has facultative anaerobic properties, and thrives in environments with high salt content (halophilic). Vibrio harveyi is often found in tropical and subtropical marine waters, especially in coastal ecosystems. Nanotechnology, which is the focus of this study, is a technology based on objects (structures) that are at the nanometer level, often used in biomedical and environmental applications. The purpose of this study was to determine the effect of SLS (nanoenzyme) in inhibiting the growth of Vibrio harveyi, which can cause disease in various marine organisms, including fish and shrimp. The method used in this study was experimental with a quantitative approach, where various concentrations of SLS were tested on bacterial growth. This study was conducted from June to July 2024, under controlled laboratory conditions. The results of this study indicate that the effect of SLS (nano enzyme) cannot inhibit the growth of Vibrio harveyi bacteria at various concentrations, namely 100%, 40%, 20%, and 10%. This is thought to be due to the particle size of the nano, where a smaller nanoparticle size can increase its effectiveness as an antimicrobial. In addition, several other methods need to be tested on SLS (nano enzyme) to understand further its ability to inhibit the growth of Vibrio harveyi bacteria, such as combining with other antimicrobial materials or modifying the nanoparticle structure.

Abstract

This study aims to evaluate the effect of fermented cassava with squid tapioca waste on the growth, survival, and feed quality of earthworms (Lumbricus rubellus) and tilapia (Oreochromis niloticus). This study used a Completely Randomized Design (CRD) with three treatments, namely the concentration of fermented cassava (10 ml, 15 ml, and 20 ml) in varying tapioca waste. The results showed that the highest specific growth rate (SGR) and increase in body length of earthworms were found in the treatment of fermented cassava 20 ml (treatment C) with values ​​of 4.40% and 19.2 mm respectively and the highest survival rate (SH) of 89.16%. Earthworm feed fermented cassava also had a positive effect on the growth of tilapia with the highest SGR value in treatment C of 1.17% and the survival rate of tilapia reaching 93.33%. Water quality parameters throughout the study remained within the optimal range for both organisms, with temperature, pH, and dissolved oxygen levels suitable for tilapia growth. This study concluded that fermentation of tapioca waste with squid by-products can improve feed quality, accelerate growth, and increase the survival rate of earthworms and tilapia, making it a sustainable alternative feed source in tilapia cultivation
