“…Further research, we suggest to applicate this method to other native or non-native fish that appear in Indonesian waters, such as Arapaima (Fadjar et al, 2019), Aligator gar (Hasan et al, 2020), Channidae (Pratama et al, 2020), Gobiidae (Hasan et al, 2021), Cichlidae (Insani et al, 2020), and Cyprinidae (Hasan et al, 2019).…”

Nemacheilus fasciatus is an Indonesian freshwater fish species that can be found in river waters on Java. This fish has a morphological similarity between species. This study aims to identify species of samples found and know their genetic kinship. This study used the Cytochrome Oxidase subunit I (COI) gene as a molecular marker, and then the results were analyzed using MEGA X software. The genetic structure and phylogeny of N. fasciatus sequences were combined with outgroup species from GenBank and analyzed using Maximum Likehood (ML), Pairwise Genetic Distance and Bootstrapping Phylogeny Model of Kimura 2 Parameters. The results showed that the primary pairs of LCO1490 and HCO2198 used to amplify the sample N. fasciatus with COI as a marker. The nucleotide frequencies of these loaches are A=26.5%, T=23.8%, C=19.9% and G=29.9%. The estimated Transition/Transversion bias (R) is 0.60. The number of haplotype diversity (Hd) was 0.972, and nucleotide (Pi) diversity was 0.05115. The kinship of N. fasciatus compared to the outgroup is closer to N. pallidus than N. chrysolaimos. Research needs to be conducted with a larger sample size for the genetic diversity of N. fasciatus in Indonesia.

“…Studies in Mexico have reported C. urophthalmus as host to a diverse assortment of parasites, including 71 different helminth species (Salgado-Maldonado 2006) and a tapeworm of the genus Bothriocephalus. Further researchers need to reobserve this population of fish in both adult and juvenile phases (Fadjar et al, 2019). Besides, measurements of sexual dimorphism are also required to analyze the females' ratio in the reservoir (Pramono et al, 2019).…”

“…Cichlidaeis a wellknown spread and invadesworldwide (Insani et al, 2020;Hasan et al, 2020a;2020b). The spread of invasive species will decrease the biodiversity of native fish that resulted in what is termed biotic homogenization and is a worldwide phenomenon (Hasan and Tamam, 2019;Fadjar et al, 2019;Islamy and Hasan, 2020). The ornamental fish trade, nutritional needsand recreational fishingis a crucial pathway for the occurrence of alien fishes from disparate regions (Bijukumar et al, 2015;Pratama et al, 2019;Serdiati et al, 2020).…”

Cladophora has a unique cellulose structure and is easy to extract. In this study, ClaNC was isolated from freshwater green algae (Cladophora glomerata) that thrived in swamps, using hydrochloric acid (HCl) hydrolysis. This study was conducted on the changes of chemical composition, morphology and structure of ClaNC through FTIR, XRD, SEM, and TEM. Lignin removal (peak 1535 cm-1) was effective after HCl hydrolysis, but bands 1028 and 894 cm-1 confirmed the identity of the chemical composition of Cladophora glomerata lettuce which was not lost even at nano-scale. XRD analysis revealed the ClaNC crystal index was 94.0% with a preferred orientation in the lattice plane of IÎ± [110] and IÎ² [200]. The surface morphology of Cladophora raw material is rod-shaped as shown by SEM, with an average diameter of 21.3 (Â± 1.01) Î¼m, whereas ClaNC refers to nanofibrils with an average diameter of 30.6 (Â± 0.85) nm as shown by TEM.

“…However, industrialization, like other human activities that impact on the environment, often results in pollution and degradation (Poddar & Sahu 2015). The pollution will decrease aquatic biodiversity although not impacted to non-native invasion fish such as arapaima and alligator gar (Fadjar et al 2019;Hasan et al 2020). Wastewater from sugar industries is one that has complex characteristics and is considered a challenge for environmental engineers in terms of treatment as well as utilization (Poddar & Sahu 2015).…”

Wastewater is the remainder of an activity released in the liquid form. Wastewater product is feared to have negative influence on the environmental balance; therefore, it is necessary to measure the quality standards of wastewater as a reference in the disposal and treatment. Bioremediation is an environmentally friendly technology utilizing microorganisms as agents in the process of cleaning or restoring wastewater conditions. The use of microorganism services can reduce the concentration of organic waste into simpler organic compounds by converting organic compounds into CO 2 , CH 4 , H 2 , and H 2 S, as well as water and energy intended for the process of growth and production of microorganisms in the remediation process. This study aims to identify the type of dominant bacteria growing in the wastewater of the sugar factory and has a potential role as a bioremediation agent for the waste. The method used in this study is the experimental, by observing several environmental parameters as indicators, among others, BOD, COD, TSS, and pH. The results of this study found two types of dominant bacteria, i.e., Staphylococcus aureus and Bacillus subtilis, then used as bioremediation agents. The bioremediation activity was able to reduce pH, BOD, and COD levels.
