Cancer is the leading cause of death in the world, with a high prevalence in Indonesia, especially breast cancer. Conventional therapies such as chemotherapy and radiotherapy have various limitations, including severe side effects and cancer cell resistance. This study aims to explore the anticancer potential of the ethanol extract of Apis dorsata Binghami nests originating from Uluway Barat Village, Tana Toraja Regency. Extraction was carried out using the maceration method with 96% ethanol solvent, with a yield of 51.42%, and bioactive compounds were identified through GC-MS analysis. Anticancer activity tests were carried out in vitro on MCF-7 breast cancer cells using the resazurin assay method . The results showed that the extract contained various bioactive compounds such as flavonoids, furanones, and aromatic aldehydes which are known to have antioxidant and anticancer activities. The IC50 value obtained was 434.30 µg/mL, indicating weak cytotoxic activity. Nevertheless, this extract showed significant ability to kill cancer cells at certain concentrations, especially 15.63 µg/mL which reduced cell viability by 44.39%. These results indicate that A. dorsata Binghami nests contain compounds that have the potential as natural anticancer agents, but require further research for fractionation and identification of more specific active compounds and further testing in vivo

The snake-head gudgeon or payangka fish (Ophieleotris aporos), tilapia fish or mujair (Oreochromis mossambicus), and marble goby or betutu fish (Oxyeleotris marmorata) are economically important fish in Lake Tondano. However, numerous community activities can disrupt aquatic biodiversity, declining Lake Tondano environmental conditions, and other factors. This study aimed to determine the relationship between length and weight and the habitat conditions of Ophieleotris aporos, Oreochromis mossambicus, and Oxyeleotris marmorata. The method used in this study was purposive sampling with research stations located at Remboken (station 1), Kakas (station 2), and Tondano Estuary (station 3). Sampling was carried out 5 times in every 10 days. The weight and length of the fishes caught in Lake Tondano were 2-60 g and 1-8 cm (Ophieleotris aporos); 9-180 g and 6-25.5 cm (Oreochromis mossambicus); and 16-30 g and 2.6-26.5 cm (Oxyeletotris marmorata), all of them have an allometric growth pattern. Oreochromis mossambicus is the most commonly caught fish in all research stations. The research station with the best level of water fertility is Remboken Station. The habitat characteristic of Lake Tondano was 25-290C of water temperature; brightness of 1.34-2.66 m; depth of 4.23-11.8 m; pH of 6.7-7.8; and dissolved oxygen of 2.27-6.31 mg/L, which still supports the well-being of the fish.

Waterbird diversity in Tondano Lake reflects ecological degradation caused by water-hyacinth invasion and sedimentation. This study analyzed the diversity and abundance of waterbirds in Tondano Lake, Indonesia, across wet (February-May) and dry (June-October) seasons in 2025 to assess their role as bioindicators of ecosystem health. Multi-season observations were carried out monthly along a 6.5 km transect at ten strategic points. Eight waterbird species from three families were recorded, with Egretta garzetta being the most abundant (29.1%) and Alcedo atthis the least (4.8%). The Shannon-Wiener diversity index (H' = 1.92) indicates a moderate level of species diversity, which reflects a pattern of ecological simplification when compared to pristine tropical lakes such as Lake Sentarum (H' = 2.5). Waterbird abundance showed significant negative correlations with water hyacinth density (r = -0.68, p = 0.032) and water depth (r = -0.72, p = 0.019), revealing that invasive vegetation and shoaling are primary drivers of habitat loss. These findings demonstrate that waterbirds function as sensitive bioindicators of ecological stress, highlighting the urgent need for integrated watershed management to prevent further community collapse.

Riparian vegetation plays a crucial role in maintaining aquatic ecosystem stability by acting as a natural buffer against anthropogenic pollution and erosion. This study analyzed the composition, structure, and ecological functions of riparian vegetation in Lake Tondano, North Sulawesi, Indonesia, with emphasis on pollutant filtration and sediment stabilization. Field surveys were conducted from May to August 2025 at ten riparian stations surrounding Lake Tondano (4,638 ha). Vegetation sampling used a stratified line transect method with fifty plots of varying sizes according to vegetation strata. Quantitative analysis included relative abundance, frequency, dominance, Importance Value Index (IVI), and the Shannon–Wiener diversity index (H’). Ecological functions were assessed through correlations between vegetation structure and reported nutrient and sediment reduction efficiencies from tropical riparian studies. A total of fifteen dominant riparian species were identified, mainly from the families Poaceae and Cyperaceae. Cyperus papyrus (IVI = 21.81%) and Metroxylon sagu (IVI = 29.65%) functioned as key ecological species, while Ficus septica showed the highest IVI (90.83%), indicating strong structural dominance. The Shannon–Wiener diversity index (H’ = 2.65) reflects moderate to high diversity. Riparian vegetation was estimated to reduce nutrient loads by 40–60% and erosion by 30–50%, highlighting its importance for ecosystem-based lake management.
