Abstract

Breast cancer is a disease that is most commonly suffered by women, with the highest number of cases and mortality rates in the world. Current breast cancer treatment still has limitations and causes serious side effects, thus encouraging the exploration of alternative therapies based on natural sources or phytochemicals. The purpose of this study is to investigate the potential anti-breast cancer properties of the traditional herbal plant Mekai (Albertisia papuana Becc.) using an in silico approach. Molecular docking analysis of JNK and EGFR targets showed that several compounds had relatively high binding affinities (-10.1 to -9.3 kcal/mol) comparable to the positive control doxorubicin, while NUDT5 had relatively moderate binding affinities to each compound. Among these compounds, 7H-dibenzo-c,g-carbazole showed the strongest binding affinity to JNK (-10.1 kcal/mol), making it potentially the most promising candidate compound. Evaluation based on Lipinski's rules shows that selected compounds from Mekai (Albertisia papuana Becc.) leaves meet the basic parameters for drug candidates and ADME-Tox predictions, including moderate toxicity (class IV), thus supporting their suitability for further development as anticancer agent candidates, while also providing a scientific basis for the use of traditional Dayak medicinal plants in the development of natural breast cancer therapies. Further research is recommended in vitro and in vivo to confirm its efficacy, safety, and clinical relevance.

Abstract

Background: Changes in tea consumption trends present opportunities for the tea industry, especially as alternative raw materials have been tested in recent years to develop tea and kombucha with distinct organoleptic and functional properties. This study evaluates the organoleptic characteristics and consumer preferences for Singkil tea and Singkil kombucha. Methodology: A sensory evaluation was conducted with 30 untrained panelists to assess color, aroma, taste, texture, and overall acceptability using a hedonic scale. Additionally, the alcohol content was measured. Findings: The results of the hedonic test indicated that all treatments fell into category 3 "slightly liked", suggesting an acceptable level of consumer preference. On average, both Singkil tea and Singkil kombucha received an acceptance score of 3, indicating that they were "slightly liked." This suggests their potential as alternative beverages suitable for commercialization. Furthermore, the safety of the product was confirmed, as it contains 0% alcohol, meets halal standards. Contribution: This study concludes that Singkil kombucha has the potential to be a viable alternative beverage for the market, and that it is safe for consumption due to its 0% alcohol content, which complies with halal standards

Abstract

The high recreational potential of Danau Biru in Panca Jaya Village a former mining site poses a risk of health hazards to visitors due to chemical contamination of the water. This study aims to evaluate the physical and chemical quality of Danau Biru’s water as a basis for recommendations on sustainable safety management of the tourist destination. This mixed-methods study employed purposive sampling in two zones (shore and center) with three replicates. Parameters were analyzed using descriptive and comparative methods in accordance with Ministry of Health Regulation No. 2 of 2023. Laboratory test results indicated extremely hyperacidic conditions with pH values ranging from 2.39–2.52 (shore) and 2.29–3.88 (center), far below the quality standard (6.0–9.0). Biochemical Oxygen Demand (BOD) values ranged from 3.68–4.96 mg/L (periphery) and 3.20–4.80 mg/L (center), exceeding the maximum limit of 3 mg/L. Meanwhile, Dissolved Oxygen (DO) was recorded at 4.1–4.6 mg/L, still meeting the minimum criterion (≥ 4 mg/L). It is concluded that the water in Danau Biru does not yet meet recreational water quality standards; therefore, swimming is strongly discouraged to prevent the risk of skin irritation and chronic toxicity to visitors.

Abstract

Lake Bukit Sempaja Indah is a post-mining water body utilized by the surrounding community for various activities, making water quality monitoring necessary to assess its condition against applicable quality standards. This study aimed to evaluate the water quality of Lake Bukit Sempaja Indah based on Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Dissolved Oxygen (DO). A descriptive quantitative approach was employed using purposive sampling at one sampling point representing an area with intensive community activities. Water samples were collected in January 2026 and analyzed in the laboratory according to Indonesian National Standards (SNI). The results showed that BOD, COD, and DO values were 1.84 mg/L, 11.10 mg/L, and 4.44 mg/L, respectively. All parameters met the Class II water quality standards stipulated in Government Regulation of the Republic of Indonesia No. 22 of 2021. The BOD and COD values indicated a relatively low organic pollution load, while the DO concentration indicated sufficient dissolved oxygen to support aquatic organisms. Based on measurements at the sampling point and during the sampling period, the water quality of Lake Bukit Sempaja Indah met Class II water quality standards based on BOD, COD, and DO parameters. Further monitoring at multiple locations and sampling periods, along with additional water quality parameters, is recommended to provide a more comprehensive assessment of the lake's condition.
