Latar Belakang: Thalassemia beta mayor merupakan gangguan pembentukan hemoglobin yang membutuhkan penatalaksanaan transfusi darah rutin seumur hidup. Peningkatan kadar feritin serum digunakan sebagai salah satu indikator penilaian risiko iron overload yang merupakan akibat dari penatalaksanaan transfusi darah berulang tersebut. Hal ini berkaitan dengan gangguan pertumbuhan yang dapat terjadi ka…
This research aims to determine the effect of electric current dan processing time of elektrocoagulatio method on decreasing TSS (Total Suspended Solid), COD (Chemical Oxygen Demand) and ammonia concentrations in the urea fertilizer industrial wastewater treatment using aluminum electrodes. This research was also carried out to determine the kinetics on the performance of the electrocoagulation…
This research aims to determine the effect of alum concentration and processing time on reducing pH levels, TSS (Total Suspended Solid), COD (Chemical Oxygen Demand) and color substance, as well as determining reaction kinetics in songket textile wastewater treatment using electrocoagulation using aluminum electrodes. The concentration of alum was varied in textile wastewater by 3 variations (1…
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…
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…
Spyware is one type of malware that threatens computer systems because it can steal users' personal information and sensitive data without their knowledge. Spyware can monitor user activities and steal data such as visited websites, email addresses, and even record keyboard and screen activities. This research aims to classify spyware attacks using the K-Nearest Neighbors (KNN) algorithm. The r…
The late adolescent phase often has difficulty controlling their own emotions, this has an impact on these adolescents, so that they deviate from the prevailing norms such as verbal aggressiveness behavior. This research is a study that uses a quantitative approach with a correlation method that aims to determine the relationship between emotional regulation and verbal aggressiveness behavior o…
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…
Imbalanced class data can affect classification performance. An imbalanced class occurs when the minority class is less than the majority class. Imbalanced class can be overcome by resampling one of them using synthetic minority over-sampling technique (SMOTE). This research aims to balance the class by applying SMOTE to the Prabumulih city rainfall event classification using the Fuzzy Naïve B…
Human activities in river estuaries are the main cause of plastic waste entering the waters. Plastic waste that enters the water will become smaller parts and is called microplastic. These microplastic particles can be eaten accidentally by biota such as Sembilang fish and will eventually accumulate in their digestive tract. Furthermore, microplastics enter and accumulate in the human body thro…
Maspari Island is one of the sea turtle nesting habitat areas in South Sumatra Province. Sea turtles are among the biota that need to be protected, so in an effort to protect sea turtles it is necessary to carry out conservation activities by identifying bio-physical conditions that are suitable for turtle habitat on Maspari Island. The purpose of this study was to determine the point and distr…
Background: Thalassemia is a hereditary blood disorder in which a genetic mutation occurs which causes reduced or absent globin chains in the hemoglobin of red blood cells. According to the Indonesian Ministry of Health in 2019, Indonesia is estimated to have 3.8% carriers of the thalassemia gene and there are around 1500 new cases every year. As the number of thalassemia patients increases, it…
Jackfruit (Artocarpus heterophyllus) is a medicinal plant that is rich in phenolic and flavonoid compounds. Phenolic compounds are known to have high potential as antioxidants. Compounds that act as antioxidants generally also have the potential to act as anti-inflammatory. This study aims to determine the in vitro antioxidant activity and in vivo anti-inflammatory activity of A. heterophyllus …
Usually, elasticity practical data collection is still done manually, which results in the data obtained having relatively low accuracy. Not only that, the time required is also long. Therefore, in this research, an elasticity practical tool was developed using the NodeMCU ESP8266 WiFi microcontroller with Spreadsheet Data Recording. The data obtained is then processed to find the spring consta…
