Abstract

One of the islands in Indonesia that is inhabited by sponges of various types is the Spermonde Archipelago, which is located in the southern part of the Makassar Strait. Sponge X. testudinaria is one of the sponges that dominates the Spermonde Islands. The difference in environmental conditions where the sponge lives causes the sponge X. testudinaria to have a different adaptation mechanism in producing secondary metabolites as self defense. Research on the of compounds from n-hexane extract sponge X. testudinaria has been carried out using phytochemical tests. Extraction begins with maceration using n-hexane solvent then the solvent is moved using an evaporator. Identification of extract functional groups using IR spectra. The results of the phytochemical screening indicated the presence of alkaloids and steroids which were supported by IR spectrum data indicating the presence of aliphatic NH, C=O and CH groups.

Abstract

Catfish (Clarias batrachus) is a freshwater fish that is cultivated commercially by Indonesian people. Catfish is the most widely cultivated fish by the community because it has various advantages such as fast growth rates, high adaptability to the environment such as stocking with high density per unit area of ponds and being able to live in aquatic environments that lack oxygen and has a good taste and high value. high nutrition. However, the presence of Edwardsiella tarda bacteria greatly affects the survival of catfish (Clarias gariepinus) because this bacteria attacks fish. This is a crucial problem because catfish have high economic value and are widely consumed and cultivated. One way that can be done to overcome this problem is by utilizing natural ingredients, namely garlic which is a natural plant that contains antibacterial properties. Garlic is one of the natural plants that contain active ingredients of sulfur compounds such as aliin, allicin, disulfide, trisulfide. This research method uses several articles related to the effect of soaking garlic extract (Allium Sativum) on the histology of catfish kidneys infected with Edwardsiella tarda bacteria and compares the differences between normal catfish kidneys and kidneys infected with Edwardsiella tarda bacteria and proves the content of garlic on catfish kidneys ( Clarias gariepinus) infected with bacteria (Edwardiella tarda)

Abstract

Various food sources and herbal plants are rich in Vitamin C, a crucial antioxidant. One such plant is Banto grass, which belongs to the Poaceae family and is commonly used as an herbal drink in many communities. It contains active compounds known for their healing and disease-prevention properties. This study aimed to evaluate the levels of vitamin C in Banto grass extract using different solvents. The research followed a descriptive approach and used UV-Vis Spectrophotometry as the analytical method. The findings showed that the vitamin C content varied significantly in Banto grass extracts prepared with distilled water, ethanol, and methanol solvents. The extract prepared with methanol had the highest vitamin C content of 4,030 ppm, which was more than the eco-enzyme water extract that contained 4,030 ppm of vitamin C. However, the extracts prepared with distilled water and ethanol solvents had lower vitamin C levels of 2,507 ppm and 3,687 ppm, respectively. This research highlights the potential of Banto grass as a rich source of vitamin C, which is essential for collagen formation, wound healing, and antioxidant activity, leading to faster wound healing and optimal tissue repair.

Abstract

This study aims to evaluate the surface water quality of ponds and swamps in the Kemampo Banyuasin Special Purpose Forest Area (KHDTK) Palembang. Water quality is vital for human life and ecosystems. Therefore, this study focused on physical, chemical and biological parameters to assess the level of contamination and cleanliness of the water. The research methods included field surveys and experiments, as well as laboratory testing. Physical parameters such as temperature, colour, and odour were measured directly, while chemical (pH, Cd, Pb, Fe, and Cu) and biological (Coliform and Escherichia coli) parameters were analysed at the Integrated Laboratory of UIN Raden Fatah Palembang. The chemical test method used Atomic Absorption Spectrophotometer (SSA), while the biological parameters were measured by Most Probable Numbers (MPN). The results showed variations in temperature between stations, with the highest value reaching 30°C. Water was generally brown or turbid in colour and odour. Coliform content ranged from 46 to 2004 MPN/100mL, while chemical parameters showed variations in pH between 5.25 to 5.55. Concentrations of heavy metals such as Cd, Pb, Fe and Cu were also measured, with the water exceeding the water quality standard for sanitary hygienic purposes (Class I), but still meeting the Class III quality standard for irrigating crops or other uses requiring similar water quality. These findings emphasise the need for better protection and management of the water.

Abstract

Indonesia black rice is a potential crop which consider to be develop as functional food because of high nutritional values. However, some agronomical traits, such as high culm and long harvesting time need to be improved for high productivity. Genetic engineering based on protoplast system is one of tools that can be used for improving black rice agronomical traits. The purpose of this study was to establish an efficient method for obtaining protoplasts, and to get information on whether the PEG-mediated transformation method can be carried out on black rice ‘Cempo Ireng’ using GFP transient expression as a marker. To get protoplast culture, we used callus and seedling as main explants. The results showed that 15th days seedling was the best explant source to get protoplast compare to callus. The combination of 1,5% macerozyme and 3% celulase was optimum to obtain the viable protoplasts. Transient expression of GFP can be done using PEG-mediated protoplast transformation in 30% concentration of PEG.
