Abstract. Retnaningdyah C, Arisoesilaningsih E, Vidayanti V, Purnomo, Febriansyah SC. 2023. Community structure and diversity of benthic macroinvertebrates as bioindicators of water quality in some waterfall ecosystems, Bawean Island, Indonesia. Biodiversitas 24: 370-378. Bawean Island is a small island with a fairly dense population, so the need for water resources is quite high. On Bawean Island, several waterfalls have been found that have a hydrological function capable of supplying water continuously for drinking water, raw materials, agricultural irrigation functions and other daily activities that are very important for the people of Bawean Island. However, the quality of the waterfall ecosystem on Bawean Island has never been studied. This study aims to evaluate the water quality of some waterfall ecosystems on Bawean Island using the community structure and diversity of benthic macroinvertebrates as a complement to water physicochemical monitoring. This study used the Ex Post Facto method. The research was conducted at 6 waterfalls found on Bawean Island. The physicochemical quality of the water observed included air temperature, water temperature, pH, Dissolved Oxygen (DO), conductivity, Biochemical Oxygen Demand (BOD), nitrate, and Total Phosphate (TP). The quality of the benthic macroinvertebrate that had been monitored included Importance Value Index (IVI), taxa richness, total density, Shannon-Wiener Diversity Index (H’), and an ecological index, namely the Family Biotic Index (FBI). The monitoring data then be used to analyze the interaction between water quality profiles and macroinvertebrates profiles by conducting Principal Component Analysis (PCA). Based on the results obtained, the water quality in the Bawean Island waterfall, according to the FBI index categorized as Good-Excellent. According to Indonesian government regulation (PP. No. 22 of 2021), some parameters of water quality in Putri and Suwari waterfall were classified as class 2, which can be used for water tourism infrastructure, fish farming also agriculture and the others are categorized as class 3 which is only used for fish farming and agriculture. To maintain good water quality, the waterfall manager needs to control human activities around the waterfall’s ecosystem.

Abstract. Karno R, Arisoesilaningsih E, Mustafa I, Siswanto D. 2024. The diversity of indigenous and potential bacteria as bioremediator of palm oil mill secondary effluent (POMSE) by metagenomics assessment. Biodiversitas 25: 1194-1200. This study aimed to identify the indigenous bacteria for potential bioremediation agents of palm oil mill secondary effluent (POMSE). Samples were obtained from the secondary pond of palm oil mill treatment. The bacterial diversity on the POMSE water samples was revealed by Next Generation Sequencing (NGS) of 16S rRNA gene amplicons. The results showed that the high abundance of bacteria phylum was Pseudomonadota or Proteobacteria (50%), Bacillota (31%), Bacteroidota (5%), and Thermotogae (3%). A photosynthetic sulfur bacterium, Allochromatium humboldtianum, was the most abundant species detected in the POMSE, with more than 8% of the total Operational Taxonomic Unit (OTU) detected. It was followed by Allochromatium phaeobacterium (6%), Allochromatium sp. (6%), and Macromonas bipunctata (6%). Meanwhile, the level of physicochemical parameters in POMSE were relatively high for several main parameters of the quality standard of palm oil industry waste, such as Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD). In contrast, oil and fat are low and meet the quality standards. The value of POMSE physicochemical parameters, including COD, BOD, and oil and fat, were 2,492.46, 852.96, and 6.20 mg/L, respectively. Metagenomic analysis showed that the bacterial community at POMSE was highly diverse. Nine dominant and codominant species found are Allochromatium humboldtianum, Allochromatium phaeobacterium, Allochromatium sp., Allochromatium vinosum, Macromonas bipunctata, Tepidibaculum saccharolyticum, Rhodocyclus purpureus, Comamonas nitrativorans, and Fervidobacterium riparium. Several indigenous bacterial species found in this research were bacteria that have potential as bioremediation agents for palm oil wastewater.

Abstract. Karno R, Arisoesilaningsih E, Mustafa I, Siswanto D. 2024. Effectiveness of micro-nanobubble aeration and phytoremediation in treating filtered palm oil mill effluent on bacteria diversity and water properties. Biodiversitas 25: 4340-4349. Palm oil waste treatment has gained much significance in recent years, as the palm oil industry has been on the rise. In addition, the biological removal of open treatment ponds and the subsequent activity of microorganisms, mainly bacteria, have been given special consideration. Therefore, this study aimed to evaluate the effectiveness of phytoremediation (Phyt) and micro-nanobubble (MnB) aeration technologies on the improvement of physicochemical properties of filtered palm oil mill secondary effluent (POMSE). The effect of the technologies on bacteria density and composition using a laboratory-scale reactor with 24-hour incubation was also explored. Metagenomic analysis using Next Generation Sequencing (NGS) and traditional methods, such as Total Plate Count (TPC) was used to evaluate bacteria density and composition. Physicochemical analyses were then conducted using an Indonesian standard method (SNI). The results showed that the MnB+Phyt reactor was more effective in reducing waste pollutants and meeting waste standards than control, MnB, or Phyt reactors after 24 hours. In addition, TPC counts showed that the highest bacteria density occurred at the 6-hour mark in the MnB+Phyt, Phyt, or MnB reactors compared to the control. Despite variations in bacteria composition among reactors, the dominant phylum and family were Pseudomonadota, Comamonadaceae, Zoogloeaceae, and Alcaligenaceae. The results also showed that MnB treatment significantly increased alpha diversity and altered genera composition. In conclusion, MnB aeration and phytoremediation technologies effectively reduced filtered POMSE pollutants with a removal percentage ranging from 28.37% to 56.69% under 24-hour treatment.

Abstract. Sombo IT, Arisoesilaningsih E, Sartimbul A, Kurniawan N, Retnaningdyah C. 2025. Seagrass diversity profile and water quality in some coastal ecosystems in East Nusa Tenggara, Indonesia. Biodiversitas 26: 5931-5943. Seagrass ecosystems provide critical services including carbon sequestration, coastal protection, and fisheries support, yet face accelerating degradation from anthropogenic pressures. Indonesia harbors 13 of 60 global seagrass species, with East Nusa Tenggara, Indonesia, supporting exceptional diversity within the Coral Triangle biodiversity hotspot. We analyzed seagrass community structure and water quality relationships across eight coastal locations spanning Timor, Rote, and Alor Islands to establish conservation baselines. Field sampling employed 120 quadrats (1 × 1 m²) along transects at 0.5-2.0 m depths, with species identification following standard taxonomic keys. Seven physicochemical parameters were measured in situ and through laboratory analysis. Eight seagrass species were documented (92% of Indonesia's flora), with coverage ranging from 2,000 to 16,000 individuals/site. Three dominant species, Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, occurred at all locations with 39% average coverage. Shannon-Wiener Diversity Index ranged from 1.5 to 2.7 (peak at Onan Ana), with 62.5% of sites maintaining moderate-to-high diversity. Critical environmental stress was widespread: nitrate exceeded standards (0.06 mg/L) at all sites by 100-717% (0.12-0.49 mg/L), temperatures surpassed optimal thresholds (> 33°C) at 50% of locations, and hypoxic conditions (DO < 5 mg/L) occurred at 25% of sites. Principal component analysis explained 69.61% of variation, revealing strong negative correlations between nutrients and diversity (orthophosphate-diversity: r = -0.78; nitrate-richness: r = -0.53). Despite environmental degradation, dominant species demonstrated remarkable resilience. Urgent conservation actions required include: implementing nutrient reduction targeting < 0.06 mg/L nitrate through watershed management, establishing thermal refugia protection at sites maintaining < 30°C, and designating high-diversity locations as genetic reserves for regional restoration programs.
