Aquaculture Water Quality Index: a low-cost index to accelerate aquaculture development in Indonesia

Abstract

Due to a lack of the related data, there were no simple water indexes available for indicating water quality. Motivated by the fact that many lakes and reservoirs in Indonesia have been polluted because of aquacultural activity, this paper proposed a Water Quality Index, called the Aquaculture Water Quality Index (AWQI), and presented the development of practical tool to aid the development of aquaculture in Indonesia. Specific purposes included: (a) providing a brief summary of the assessment results of the existing WQI; (b) developing the AWQI method for applying in an aquacultural context; (c) implementing the AWQI method in Depok Area (Indonesia) as study area. An AHP method was also processed to define the weights of selected water quality parameters: DO, ammonia, pH, and fecal coliform. The AWQI had several features: (a) a low-cost water quality monitoring program that could be used by developing countries; (b) a useful tool for water resource agencies, especially for local agencies, to manage waterbodies and to raise public awareness of water pollution for its data, as its data could be easily understood and interpreted.

Measuring the Aesthetic Value of Multifunctional Lakes Using an Enhanced Visual Quality Method

“…The results of this study show that aesthetic value is one of the important variables that should be considered when examining multifunctional lakes. The presented results also strengthen the results from a previous study [8] in that the physicochemical parameters are not sufficient to measure comprehensive quality index of a lake without considering perceived attributes of the lake. Three criteria (visual ecology, functional morphology, and financial profitability) in the perceived attributes also can be used as indicators of the density of obstructing objects in the multifunctional lake environment.…”

“…Lakes are an important form of freshwater with a range of aquatic ecosystems and eco-hydrological functions [1][2][3], including being natural regulators of river flows and sedimentation, functioning as nutrient traps in watershed areas, creating aquatic habitats, and even providing high biodiversity in specific environments [4,5]. In addition, lakes are also used for anthropogenic purposes such as for drinking, agriculture, aquaculture, and other recreational purposes such as fishing, sailing, swimming, jet-skiing, boating, paddling, canoeing, and other forms of water-based tourism [6][7][8]. Therefore, aesthetic value is an important factor that should be considered in multifunctional lake environments.…”

A Micro-Scale Study of Flood Risk Assessment in Urban Fluvial Areas Using the Flood Potential Index

“…Concerning these issues, various methods are being offered by using geographical information system (GIS)-based model applications in order to solve flood risk assessments in large-scale studies (Singh, 2019;Song et al, 2017;Valencia et al, 2020; and the relationships to the position of the groundwater table (Al Adaileh et al, 2019;Freitas 2016;Nistor et al, 2019;Olaniyi Oke, 2018;Suryawan et al, 2019;Syarif et al, 2013;Wu et al, 2011). Another method is by using the water index in order to describe or analyze water-related problems (Tallar and Dhian, 2021;Nayak et al, 2020;Wang et al, 2020;Williams et al, 2019;Tallar and Suen, 2015;Tallar and Suen, 2016). Therefore, many studies have also combined the water index with a GIS-based model (Kawo and Karuppannan, 2018;Taloor et al, 2020), and further studies developed a flood index by using a GIS based-model (Yang et al, 2017;.…”

Enhancing the productivity performance of Cyprinus carpio L. by Manihot utilissima Pohl. leaves supplementation

“…However, the demand for C. carpio L. shows an increasing trend but not in line with its productivity rate. Some factors that should be considered in aquaculture activity consisted of water quality (Davidson et al, 2013;Tallar & Suen, 2016), disease (Stentiford et al, 2012;Stentiford et al, 2017), microalgae-bacteria interactions (Natrah et al, 2014), biosecure (Bhowmick & Crumlish, 2016;Hasimuna et al, 2020), and nutrition ((Mente et al, 2011;Belton et al, 2014;Ekasari et al, 2016). Moreover, the use of antibiotics as disease control in aquaculture may pose a negative impact on human health, since antibiotics can leave residues in aquatic organisms that are harmful to world food security (Li et al, 2006;Zhang et al, 2014).…”
