“…Moreover, unlike periodical chemical analysis, the use of living organisms provides a more rounded measure of water quality as they are affected by overall environmental factors, not just those that are the focus of any specific experiment (Michels et al, 1999). There are multiple ways in which animals can be used as bioindicators, for the most part, through observing behavioural, ecological or physiological changes (Manickavasagam et al, 2019). Changes in behaviour can present themselves through abnormal feeding patterns, swimming patterns, burrowing behaviours etc.…”

“…Physiological changes could be CO 2 production, accumulation of heavy metals, different protein synthesis etc. and are usually traceable on an individuallevel (Manickavasagam et al, 2019;Holt and Miller, 2011). Below, we consider the constituent parts of our proposed biohybrid in detail.…”

In the wake of climate change and water quality crisis, it is crucial to find novel ways to extensively monitor the environment and to detect ecological changes early. Biomonitoring has been found to be an effective way of observing the aggregate effect of environmental fluctuations. In this paper, we outline the development of biohybrids which will autonomously observe simple organisms (microorganisms, algae, mussels etc.) and draw conclusions about the state of the water body. These biohybrids will be used for continuous environmental monitoring and to detect sudden (anthropologically or ecologically catastrophic) events at an early stage. Our biohybrids are being developed within the framework of project Robocoenosis, where the operational area planned are Austrian lakes. Additionally, we discuss the possible use of various species found in these waters and strategies for biomonitoring. We present early prototypes of devices that are being developed for monitoring of organisms.

“…Microorganisms are frequently used as indicators for natural ecosystems as they are abundance and easily being tested. According to Manickavasagam et al (2019), some microorganisms develop stress proteins when exposed to pollutants such as Cadmium and Benzene. This scenario can be used as signals for the ecosystem that had been polluted.…”

“…The assessment of water conditions can be conducted with two approaches as follows, using biota response to environmental pressure, and determining the water quality using environmental conditions as a bio-indicator (Prato et al, 2009;Ritter et al, 2009;Sundaravaman et al, 2012;Trishala et al, 2016;Stancheva and Sheath 2016;Sahidin et al, 2018;Manickavasagam et al, 2019). Assessing water conditions with a biological method is better than the physical-chemical methods, which describes conditions in short-terms (Junshum et al, 2008;Bhateria and Jain, 2016).…”

Cijulang River is one of the leading ecotourism objects in Pangandaran, West Java Province, Indonesia. However, the river has a variety of activities that can increase the water pollution in the river such as Green Canyon cliffs tourism, ecotourism of mangrove conservation, housing, and industrial siting. Macrobenthos is one of the bio-indicators that can assess the rate of water pollution in rivers, especially their organic pollutants. Therefore, this research aims to determine water pollution status in Cijulang River Tourism by comparing various biotic indices. The study was conducted at four site sampling locations from upstream to downstream in the rainy season period and dry season period using different methods namely, line transect model, water quality assessment by biological indexing (diversity, species dominant, and family biotic), species deficit, and organic measurement. The research showed 5873 macrobenthos and divided into 27 species with an average abundance of 167 ind.m-2 and are mainly dominated by gastropod species Faunus ater (40%). They are extreme species that can live in high organic pollution and water salinity. This divided the research of quality water assessment of Cijulang River into three categories as follows: slightly polluted (score 36-46) at Green Canyon site, moderately polluted (score 50-60) at Boat Shelter and Muara Cijulang location, and highly polluted (score 66) at Nusawiru site.Keywords:RiverBio-indicatorOrganicAquatic pollution
