Abstract

This review explores the impact of aquatic invasive species as biological pollutants that disrupt ecosystems globally, including in Indonesia. Invasive species often exhibit rapid growth and reproduction due to their adaptive advantages, which, combined with human activities and favorable environmental conditions, accelerate their spread. These species alter the balance of marine and freshwater ecosystems, posing significant challenges for biodiversity conservation and resource management. Various regulatory measures have been implemented internationally, such as the European Union’s blacklist of invasive species and Indonesia’s legislative framework, to prevent their spread. Additionally, remediation techniques like zooremediation, using bivalves to mitigate biological pollutants, have been applied to manage these species. The review also highlights challenges in controlling invasive species, including the need for comprehensive ecosystem assessments and strategies like Top-Down and Bottom-Up modeling for management. Ultimately, a deeper understanding of the invasive species' ecological effects is essential for developing more effective control measures and policies, ensuring the protection of aquatic environments and mitigating the global spread of invasive species.

Abstract

Myristica fragrans Houtt. has been widely explored due to its high chemical composition and many functional features, nevertheless, the analytical framework applied to analyze this species has progressed unevenly. This study critically discusses the shift from conventional GC–MS-based phytochemical profiling to more integrated metabolomics techniques incorporating LC-HRMS, chemometrics, and bioactivity analysis in nutmeg research. A literature study was undertaken in five scientific databases using PRISMA guidance. Studies were categorized as MAIN and SUPPORT to distinguish between metabolomics-driven studies and studies providing complementary evidence of phytochemical and bioactivity data. The synthesis illustrates that most of the published work still depends on GC–MS analysis of volatile fractions and essential oils, but fully untargeted metabolomics investigations are rare. Recent developments have increased metabolite coverage, sample discrimination and helped identification of potential markers related to bioactivity interpretation, species authentication and quality assessment. Most studies still tend to report relationships between metabolites and bioactivity mostly as compositional or statistical associations, biomarker verification remains patchy across the literature and metabolite annotation is still often limited to MSI Level 2 or 3, although examples of higher-confidence identification are emerging. In sum, contemporary M. fragrans research can best be characterized as a shift from extended phytochemical profiling to more biologically interpretable metabolomics. Future advances will depend on increased standardization, more confident metabolite annotation, stricter chemometric validation, and wider integration of chemical signatures with functional biological evidence to enable more robust and translatable applications of nutmeg metabolomics.

Abstract

Zainudin IM, Patria MP, Rahardjo P, Yasman, Gautama DA, Prawira WT. 2017. Bycatch of sharks, marine mammals and seabirds in Indonesian Tuna Longline Fishery. Biodiversitas 18: 1179-1189. Bycatch in longline fishery is recorded to be one of the major factors defining the declined populations of endangered marine species worldwide. This research aimed to identify bycatch level of sharks, marine mammals and seabirds as well as to pinpoint the mitigation options in Indonesian tuna longline fishery. In this study, a total of 8,564,858 hooks were observed from 5,622 gear settings in Indonesian tuna longline fishery based in two major fishing ports, namely Bitung Fishing Port-North Sulawesi and Benoa Port-Bali from May 2006 to June 2014. The results suggest that the best hook rate per thousand hooks in Indonesian tuna longline fisheries for shark bycatch was 0.2446, followed by 0.0030 for seabird bycatch, 0.0021 for dolphin bycatch and 0.0009 for whale bycatch. Seabirds largely acquired in the dead condition while the other species were found still alive (sharks and marine mammals). Bycatch of seabirds only occured in the vessels based in Benoa Bali, and the correlation value (R2) of sharks and seabirds caught at night time was low while for marine mammals was very strong. Deep setting system of fishing gears and night setting also proved to be more effective to reduce bycatch of those critical marine species.

Abstract. Dharmayanti N, Supriatna J, Abinawanto, Yasman. 2019. Isolation and partial characterization of Alginate from Sargassum polycystum of Banten, Indonesia. Biodiversitas 20: 1776-1785. The utilization of Sargassum polycystum as an alternative alginate source may reduce the dependence on alginate import as currently alginate demands in Indonesia are 100% supplied from overseas. The purpose of this study was to characterize alginate extracted from Sargassum polycystum obtained from three locations with different ecological characteristics. Isolation of alginate was conducted through partial hydrolysis to separate guluronic acid and mannuronic acid followed by freeze-drying and then the parameters were measured qualitatively and quantitatively using FTIR. The results showed that alginate extracted from Sargassum polycystum collected from Lima Island, Ujung Kulon and Binuangeun were 11.48%, 18.62%, and 5.75%, respectively with the viscosity were 35 cP, 62.50 cP, and 81.33 cP, respectively. The test result of partial hydrolysis of alginate showed that guluronic block (GG) in the alginate polymer of Lima Island, Ujung Kulon and Binuangeun were 67.60%, 59.00%, and 41.40%, respectively. These relate to the nature of the gel formed. The alginate from Lima Island tends to be more rigid and less flexible than that from Ujung Kulon and Binuangeun. The findings of this study suggest that there are differences in the concentration of the components of mannuronate and guluronate of Sargassum polycystum across different locations in Banten, Indonesia.

Abstract. Fadhilah QG, Santoso I, Yasman. 2021. The antagonistic activity of marine actinomycetes from mangrove ecosystem against phytopathogenic fungi Colletotrichum sp. KA. Biodiversitas 22: 642-649.  Marine actinomycetes from mangrove ecosystems are known to be potential antifungal-producing isolates against phytopathogenic fungi. The aim of this research was to obtain potential marine actinomycetes isolates against the phytopathogenic fungi Colletotrichum sp. KA. Screening of 15 marine actinomycetes isolates using a dual culture method with a plug technique showed that 80% of isolates have antagonistic activity, represented as a percentage of growth inhibition range from 47.96% to 84.94%. Among 12 potential isolates, six isolates (SM4, SM11, SM14, SM15, SM18, and SM20) were evaluated for delayed antagonistic activity with incubation periods of 6, 9, and 12 days using the plug and streak techniques. The results showed that the percentage of growth inhibition of selected isolates inclined to increase along with the incubation period prior to inoculation of Colletotrichum sp. KA. Delayed antagonist assays using the streak technique resulted in higher inhibition results compared to the plug technique. Furthermore, the non-delayed assays of the two selected isolates, SM11 and SM15, also inhibited Colletotrichum sp. KA 57.99% and 59.88%, respectively. The delayed antagonist assay with a shorter incubation period of the two selected isolates also showed an increased percentage of growth inhibition of Colletotrichum sp. KA. According to our research, the delayed antagonistic assay of marine actinomycetes isolates with a 12-day incubation period using a plug technique was representative to evaluate the percentage of growth inhibition.

Abstract. Wibowo NA, Mangunwardoyo W, Santoso TJ, Yasman. 2021. Effect of fermentation on sensory quality of Liberica coffee beans inoculated with bacteria from saliva Arctictis binturong Raffles, 1821. Biodiversitas 22: 3922-3928. Fermentation is one of the post-harvest steps that influence the quality of coffee. This study aims to determine the sensory quality of Liberica coffee beans cv. Liberoid Meranti (LiM) fermented using a consortium of bacteria from saliva Arctictis binturong Raffles, 1821 with varying fermentation periods. Fermentation was performed in a wet process for 0, 4, 8, 12-hours in triplicate. The parameters observed were caffeine, protein, and fat content. The sensory quality of brewed coffee was conducted refers to the standard Speciality Coffee Association (SCA). The data obtained were processed with Minitab version 16 for Windows and analyzed using ANOVA with a level of 5% and followed by a post hoc test. The results showed that coffee fermented for 0, 4, 8, 12 hours has protein content of 15.31-15.67%; 15.09-16.62%; 12.71-13.07%; 14.64-14.69%; fat content of 9.48%; 10.20%; 9.96%; 10.21%; and caffeine content of 1.05%; 0.99%; 0.96%; 1.02%, respectively. The length of the fermentation period affects significantly (p<0.05) the content of protein, fat, and caffeine. The final score of cupping test in coffee fermented for 0, 4, 8, and 12 h were 77.63; 78.13; 82; and 80.25, respectively. A fermentation period of 8 and 12 hours improve the flavor score that categorized fermented Liberica coffee as specialty coffee (8.00 - <9.00 = superior).

Abstract. Basith A, Abinawanto, Kusrini E, Yasman. 2021. Genetic diversity analysis and phylogenetic reconstruction of groupers Epinephelus spp. from Madura Island, Indonesia based on partial sequence of CO1 gene. Biodiversitas 22: 4282-4290. Groupers populations in Indonesia, particularly from Madura Island, East Java are indicated to be over-fished, thereby requiring data collection of more accurate genetic resources as an important step for grouper conservation. A total of 14 samples of the Epinepheplus groupers were obtained from the fish landing port on Madura Island. The 617 bp CO1 gene sequence was utilized for genetic diversity analysis and phylogenetic tree reconstruction. Genetic diversity is based on the value of haplotype diversity (Hd) and nucleotide diversity (?). Reconstruction of the phylogenetic tree includes neighbor-joining (NJ) implementing K2P substitution model, while maximum likelihood (ML) is conducted by implementing HKY+G+I substitution model, both of which were evaluated by employing a bootstrap of 1000 replications. Analysis of genetic distance between species indicated that the farthest distance between E. heniochus and E. fasciatus was 0.189, while the closest distance between E. erythrurus and E. ongus was 0.099. Intrapopulation genetic diversity indicated a high value with details of Hd=0.978 and ?=0.12107. Furthermore, NJ and ML phylogenetic tree demonstrated similar topology in the observed Epinephelus spp. obtained from Madura Island grouped into 7 clades, that is Epinephelus coioides, E. bleekeri, E. areolatus, E. erythrurus, E. heniochus, E. fasciatus, and E. ongus.
