Abstract

Indonesia's diverse climate types, influenced by its unique geographical features, pose significant environmental challenges, including water quality issues related to turbidity and Total Dissolved Solids (TDS). Many Indonesians lack awareness of water quality, particularly turbidity, which can harbor harmful microorganisms. To address these challenges, this study employs digital image processing and machine learning, specifically Support Vector Machine (SVM) algorithms, for water quality assessment. A dataset of 80 water images, categorized into seven turbidity classes, is used to train and test the model. Results show a clear correlation between turbidity levels and TDS concentrations and pH values. The system accurately assesses water suitability for different sources, offering a user-friendly and cost-effective solution for water quality monitoring in dynamic environmental conditions. However, limitations include the dataset size and the narrow focus on turbidity. Future research could expand to encompass a broader range of water quality factors. This approach holds promise for enhancing water quality management in Indonesia and similar regions.

Abstract

Heavy metal contamination of traditional herbal medicine (jamu) is a threat to humans, especially at levels above known threshold concentrations. Traditional herbal medicine found in Banda Aceh City – Indonesia, polluted by heavy metals cadmium (Cd), lead (Pb), and mercury (Hg) was performed. Heavy metal analysis used Flame - Atomic Absorption Spectrometry (FAAS) and Chemical Vapor Generation - Atomic Absorption Spectrometry (CVG - AAS) methods. The validation of the method was performed to obtain more accurate heavy metal analysis results for the samples. Heavy metal contamination, especially Pb metal, with concentrations of 4.32 ± 0.14 mg/Kg to 29.25 ± 0.24 mg/Kg. The Cd metal contamination was only found in herbal medicine sample E with a concentration of 0.80 ± 0.02 mg/Kg, above the threshold. The Hg metal contamination was also found with concentrations of 0.20 ± 0.01 to 2.14 ± 0.06 mg/Kg, and some were not detected. The government should be very concerned about stopping the distribution of herbal medicine that can be harmful to health and should inspect drug stores that still sell herbs that do not have established standards.

Abstract

Bioethanol (C2H5OH) is an organic chemical widely used as a solvent. It is also applied in producing germicides, beverages, antifreeze, fuel, and depressants as an intermediate in producing other chemical substances. Generally, bioethanol is generated from the fermentation of glucose (sugar) accompanied by a distillation process. This study aimed to optimize bioethanol production against variations in pre-treatment and solvent concentrations through enzyme hydrolysis and fermentation of oil palm empty fruit bunches. The pre-treatment is an important stage in the conversion process of lignocellulosic biomass, as it eliminates lignin, reduces the crystallinity of the cellulose, and increases the porosity of the substance, thereby facilitating the hydrolysis process and glucose fermentation. The process was carried out with different concentrations of acid, base, and organolsov solvents, after that, it was hydrolyzed using cellulase enzymes for 24 hours and fermented using Saccharomyces Cerevisiae yeast for 5 days. Furthermore, the bioethanol produced was separated through a rotary vacuum evaporator at 180 rpm and a temperature of 78 °C. The highest ethanol content produced was 7.8% with 4% NaOH and 90 minutes of pre-treatment residence time.

Abstract

Bakông Asóe is a typical Acehnese snack loved by older people in Aceh since ancient times. This snack is made from wet tobacco which is used as chewing tobacco. The process of drying Bakông Asóê in the open triggers heavy metal contamination by air pollution from motor vehicles. The process of storing Bakông Asóê in a wet state also triggers the growth of microbes such as bacteria and fungi due to a growth medium in the form of water. The purpose of this study was to determine the content of heavy metal contamination (Pb, Cd, Se, Cu and Hg) and microbiological contamination in the form of bacteria (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa) and fungi (Candida albicans and Aspergillus niger) in Bakông Asóê which sold on the side of the road without adequate hygiene. The research refers to a qualitative research approach with the type of research that is descriptive research. This study showed that heavy metal exposure in the form of Pb, Cu and Se in the three samples was still in the safe range for consumption. However, exposure to heavy metals in the form of Cd and Hg in the three samples exceeded the consumption standard. The results of the analysis of microbiological contamination in the three Bakông Asóê samples were proven to contain bacterial and fungal contamination, where cocci-shaped bacteria were more commonly found and fungi with the genus Aspergillus sp were also more dominant in the three Bakông Asóê samples. The conclusion of this study is positive for chemical and microbiological contamination in Bakông Asóê, which is sold in Aceh, Ule Kareng and Lambaro Markets.

Abstract

The issue of kidney health has emerged as a global public health concern. Kidneys play a vital role in eliminating toxic substances and maintaining fluid and chemical balance in the body. Preserving kidney health is tantamount to safeguarding overall bodily health, as kidney damage can adversely affect other organs and organ systems. This can give rise to various ailments and compromise one’s physical condition. Throughout ancient history, plants have been employed for medicinal purposes in treating a wide array of ailments with one such plant being tea (Camellia sinensis L). Tea is renowned for its antioxidant and anti-inflammatory properties. It contains bioactive compounds, notably polyphenols, which contribute to enhancing health. Polyphenols serve as therapeutic agents for the kidneys and can prevent the onset of other degenerative disease. Prior research has demonstrated that EGCG, a derivative of polyphenols, can safeguard the kidneys against ischemia-reperfusion injury, kidney fibrosis, and inflammation. Catechins, a subcategory of polyphenols, act as antioxidants, anti-inflammatories, and anti-apoptotic agents, thereby shielding kidney cells.

Abstract

Uncovering the therapeutic potential of secondary metabolites produced by plants, animals, and microbes constitutes the foundation for the development of novel medications. The objective of this investigation is to discern the classes of secondary metabolites and assess the antibacterial properties of endophytic fungal extracts obtained from Chrysanthemum indicum L. flowers. Through the isolation process, five isolates designated as JEC1, JEC2, JEC3, JEC4, and JEC5 were identified. The cultivation of endophytic fungal isolates spanned a three-week period before undergoing extraction with ethyl acetate. The phytochemical tests revealed the presence of alkaloids, flavonoids, steroids, terpenoids, saponins, and tannins in the ethyl acetate extract. Antibacterial activity was determined using the agar well diffusion method, with ciprofloxacin serving as a positive control. Notably, all ethyl acetate extracts from endophytic fungi exhibited antibacterial activity. The most substantial inhibitory diameter against Staphylococcus aureus was recorded as 19.1±0.8 mm for the JEC3 endophytic fungi, while Escherichia coli exhibited an inhibitory diameter of 16±1.1 mm for the JEC2 endophytic fungi.
