Abstract

This study aimed to isolate and characterize β-sitosterol from the marine hydroid Aglaophenia cupressina Lamoureoux and evaluate its antibacterial and antifungal activities against Xanthomonas campestris and Fusarium oxysporum. β-Sitosterol was extracted, purified, and identified using spectroscopic techniques, including infrared and nuclear magnetic resonance spectroscopy. Antimicrobial activity was assessed through agar diffusion method to determine its inhibitory effects on bacterial and fungal growth at varying concentrations. β-sitosterol is a crystalline compound, with a melting point of 138-139°C, consistent with the reported range for pure β-sitosterol, indicating high purity. Infrared (IR) spectroscopy revealed key functional groups, including a hydroxyl group at 3433 cm⁻¹, C-O stretching at 1050 cm⁻¹, and aliphatic hydrocarbon chain vibrations at 2956, 2938, and 2869 cm⁻¹. The C=C stretching at 1634 cm⁻¹ and C-H bending at 1465 cm⁻¹ confirmed its unsaturated sterol structure. ¹H NMR spectroscopy further confirmed the structure with characteristic methyl and olefinic proton signals. The antibacterial activity of β-sitosterol against Xanthomonas campestris showed a concentration- and time-dependent effect, with the highest efficacy observed at 60 ppm, demonstrating potential as a natural antibacterial agent. Additionally, its antifungal activity against Fusarium oxysporum revealed both fungistatic and fungicidal effects, with lower concentrations exhibiting fungistatic behavior and higher concentrations displaying fungicidal activity, thereby offering versatility for both fungal inhibition and eradication. This dual action, combined with its well-characterized molecular structure, positions β-sitosterol as a promising candidate for further development as an antimicrobial compound. The findings underscore the accuracy of the identification process and highlight β-sitosterol's potential in pharmaceutical and agricultural applications, particularly in combating bacterial and fungal infections.

Abstract

Graphical Abstract   Highlight Research Approximately 3978 sponge individuals were collected and grouped to 137 morphospecies, with 120 of these have been identified intothree classes, 17 orders, 40 families, and at least 70 genera. Sponges in the Makassar Strait showed significant differences based on individual abundance data. Pannikiang Island had the greatest abundance and diversity of sponges, and the lowest found in Gusung Toraja. The sponge composition of the three islands indicated that neighboring islands do not guarantee high similarity.     Abstract Sponges are an important and dominant component of marine benthos which are threatened due to global environmental degradation. To establish appropriate conservation policies, the diversity and distribution of sponge must be understood. Meanwhile, the availability of sponge diversity and distribution especially in the Makassar Strait, is still lacking. This study aimed to investigated the diversity and distribution of the sponges composition in coral reef ecosystems on three less-explored islands in the Makassar Strait (South and West Sulawesi provinces, Indonesia). Sponge assemblages were sampled at a depth of 5 m using Underwater Photo Transect method, with a total area of 15 m2 at each site. We recorded a total of 137 morphospecies of sponges (N = 3978 individuals), 59 of which were restricted to Barrang Caddi, 39 to Gusung Toraja, and 92 to Pannikiang. Only 12 species were shared among all islands. We found ten morphological types of sponge, with the dominant type in all islands was encrusting. Our results showed that Pannikiang island represents the  highest diversity and abundance of sponges, which had the largest area compared to the other islands and is surrounded by mangrove forests. There was a significant difference in species composition between Pannikiang and other islands.

Abstract

The Research on “Coral Coverage in Baranglompo Island and Bone Batang Island Based on Reef Check Method” was conductedin April 2016. The aims of this study was to determine and to compare the condition of reefs in Baranglompo and Bone BatangIslands based on the percentage of life coral cover by using Reef Check methods. This study also aims to determine whichfactors that most affect the percentage of coral cover on each island i.e: abiotic factors (temperature, salinity and substrate inthe form of rock, rubble, sand, silt/clay); biotic factors (soft coral, recent killed coral, algae, sponges, fish and invertebratesassociate) and anthropogenic factors (garbage, ilegal fishing/bombs, stun, anchors, nets) were also investigated. Percentage oflife coral cover obtained by Line Intercept Transect (LIT) along 100 meters at a depth of 3 meters and 10 meters. The resultsshowed that the condition of coral reefs in Baranglompo was classified as moderate with an average percentage coral coverageof 42% at a depth of 3 meters and 27% at a depth of 10 meters. While the condition of coral reefs in Pulau Bone Batang wasrelatively good with average coral cover of 51% at 3 meters depth and moderate with average coral cover of 39% at 10 metersdepth. Condition of coral reefs in Bone Batang is better than Baranglompo islands. Anthropogenic impacts in the form of wasteis the most influential factor on coral cover on the island Baranglompo. Whereas fishing activities by using dinamite are thefactors that most influence on coral cover on the island of Bone Batang.Keywords: Coral coverage, Baranglompo island, Bone Batang island, Reef Check

Abstract

The research aims to determine the relationship of water quality parameters to the growth and carrageenan quality of red algae Kappaphycus alvarezii. This research was conducted in July November 2022 in the waters of Belopa sub-district, South Sulawesi, Indonesia. Water quality parameters measured were temperature, pH, salinity, brightness, depth, current velocity, dissolved oxygen, nitrate, and phosphate. The cultivation was conducted by longline method. There were 3 stations and each station had 3 stretched ropes with a length of 5 m as replicates. The growth was calculated by measuring the specific growth rate and the absolute weight growth. The quality of carrageenan was tested by yield, water content, and ash content. Water quality and growth data were collected every 10 days for 40 days. The effect of growth and quality of carrageenan on each location was analyzed through ANOVA and Kruskal Wallis tests. The relationship between parameters was analyzed through coefficient correlation tests (Pearson Simple Linear Correlation). The determination of characteristic parameters at each station was applied through the principal component analysis test. The results showed that the yield of carrageenan was impacted by phosphate. The water affected by nitrate and brightness. Ash content affected by temperature, pH, and current velocity. Different location  did not significantly affect the growth and quality of carrageenan.

Abstract

Pollination decline has become a major ecological concern in tropical agroforestry systems, where habitat simplification reduces floral diversity and threatens pollinator stability. This study aimed to evaluate early ecological responses to vegetation enrichment designed to restore pollination function in a community-managed agroforestry landscape in South Sulawesi, Indonesia. A paired-plot experiment was established to compare two adjacent plots (each 0.25 ha), an enriched plot and a control plot, in which floral diversity, foraging activity, colony productivity, and microclimatic parameters were monitored from September to November 2025. Indices of diversity and comparative statistical tests were used to analyse ecological variables and assess treatment effects. Shannon-Wiener floral diversity indices (H') increased from 1.45 to 1.66 after vegetation enrichment, resulting in greater phenological overlap in relation to the control plots as well. These changes correspond to a substantially increased rate of stingless bee (Tetragonula biroi) visits and a higher return frequency in enriched plots (p < 0.05). An increase in foraging activity was observed, with a significantly greater extension of the brood area and a rise in honey production, reflecting improved colony performance. Also, microclimatic measurements indicated lower temporal variance in ambient temperature and light intensity under enriched vegetation, suggesting a dampening effect on more stable foraging conditions. In general, these results imply that small-scale vegetation can induce an early return to functioning through a trade-off effect on resource diversity, colony strength, and environmental stability in the context of community agroforestry systems and do not contradict community-based landscape management.
