Plastic is an object with a high level of use in society and most of its use is single use only. Plastic that floats and settles in water will be degraded into smaller particles called microplastics. The very small size of microplastics means that microplastics are often considered food by marine biota, one of which is the blue swimming crab (Portunus pelagicus). Microplastics that accumulate i…
Sungsang Village is located at Musi River, the estuary area is a semi-enclosed body of water that is in free contact with the sea. The lack of awareness of the Sungsang coastal community causes plastic waste to enter the water and contribute to damage and result in a decline in water quality. Wide distribution of plastic waste causes microplastics to easily stick to and be ingested by the mudsk…
Microplastics are a form of plastic waste that is very difficult to detect because they are very small and easily dispersed in the ocean. The danger of microplastic contamination to biota can cause physical damage, reduce growth rates and tend to be toxic. This study aims to analyse the abundance of microplastics, identify type of microplastics in shrimp Penaeus merguiensis and Litopenaeus vann…
Free radical can trigger chain reactions that cause damage to cell-forming particles that can have an impact on health. One of the plants that has the potential as a source of antioxidants is purple sweet potato leaves (Ipomoea batatas L. Poir) which contains a secondary metalbolite component with antioxidant effectiveness relatively higher than tocopherol. This study aims to determine the Anti…

Sungsang Coastal Waters, South Sumatra is the estuary of the Musi River which has potential for capture fisheries production. The many daily activities that people tend to carry out around the Sungsang Coast of Banyuasin, South Sumatra have the potential to reduce water quality and increase the concentration of heavy metals Pb and Cu. The purpose of this research is to analyze the concentration…
One source of marine pollution that is often found is plastic waste. Plastic waste thrown away in coastal areas can be carried by ocean dynamics such as strong currents and settle in important coastal ecosystems such as mangroves, seagrass and coral reefs. Plastic waste that is degraded over a long time will turn into microplastics. Microplastics can accumulate in marine biota through various o…
PT Nutri Choco Nusantara or known as Nichoa is a new company focused in the healthy chocolate industry using local ingredients in Indonesia. Given the number of business competitors in the same business, company owners must be able to make efforts to prevent customer movement, because satisfied customers can provide many benefits to the company such as enabling customer loyalty. For this reason…
DKI Jakarta's air quality has changed as a result of increased physical development of the city and industrial centers. Currently the air is drier and dirtier than before, if this is allowed to continue it will have a negative impact on living things. Therefore, research is needed on the classification of DKI Jakarta's air quality which is expected to help the DKI Jakarta Environment Agency to …
Diabetic Retinopathy is a condition that often causes blindness in the retina. One characteristic of diabetic retinopathy in the retina is the presence of exudates. Exudates segmentation is one way to detect diabetic retinopathy. A commonly used method for exudates segmentation is Convolutional Neural Network (CNN). One architecture found in CNN methods is U-Net.. Even though it is successful i…
Melinjo leaves has pharmacological activity as an antidiabetic because it contains flavonoid compounds which can inhibit glucose absorption, stimulate insulin secretion or act as insulin and can regulate the work of enzymes that play a role in carbohydrate metabolism. The effectiveness and bioavailability of extracts tend to be low so that the formula in the form of nanosuspension is an option …
Melinjo leaves are known to have pharmacological activity as antidiabetics because they contain flavonoid compounds that can reduce blood glucose levels with their ability to act as antioxidants that protect β-cell damage as insulin producers and can increase insulin sensitivity. The effectiveness, bioavailability, and solubility of extracts tend to be low, so the formula in the form of nanosu…
Plastic waste in the waters can have an impact on ecosystems in marine and coastal waters. Plastic waste will degrade into microplastics. Microplastics can enter the digestive tract of fish and cause changes in fish metabolic processes, disrupt the immune system of fish and have the potential to contaminate humans who eat them. This study aims to analyze the types, characteristics and abundance…
Musi River is one of the longest rivers in Sumatra, many activities along the Musi River flow ranging from sand mining activities, industrial activities, ports, transportation to settlements. The high level of community activity has directly increased waste disposal and polluted the waters of the Musi River. One of them is the disposal of plastic waste which can later form microplastics. Microp…
