Abstract

Air pollution increases the likelihood of developing a variety of health issues, particularly in the field of respiration. Involuntary exposure to traffic-related air pollution affects humans from fetal development to death. Nitrogen dioxide, sulfur dioxide, carbon monoxide, benzene, ozone, particulate matter 10 (PM10), lead, arsenic, cadmium, nickel, benzopyrene, and particulate matter 2.5 (PM2.5) are among the lung-damaging substances found in air pollutants. Determining the causal relationship between various major road pollutants and the human respiratory system is a difficult task. In general, it can be concluded that traffic-related pollutants will induce an inflammatory response that will progress based on the variation of humans exposed. The concept of oxidative stress resulting from traffic-related pollutants has also begun to receive extensive research. This gives hope for assisting the human anti-oxidant system in combating the increasingly difficult-to-avoid threat of air pollution.

Abstract

It is widely accepted that human existence has now changed dramatically as a result of the Fourth Industrial Revolution in terms of thinking, living, and interacting. The fast advancement of technology has had a significant impact on this transition. Equally significant is the impact of the Fourth Industrial Revolution on education. To be able to synergize with the world's rapid growth, education, the engine of cultural change and progress, must be responsive to the onset of this era. Human resource management is the most important factor in enhancing the quality of education so it can adapt to rapidly-changing circumstances in order to deal with this type of change. Human resource management can benefit from an understanding of human relations. This method is effective for humanizing employees in organizations, allowing them to work safely, cheerfully, and with a sense of fulfilment because they are respected. High school education is intended to prepare students to manage human resources effectively. Human connections should prepare high school students for the fourth industrial revolution.

Abstract

Ethanol, also known as ethyl alcohol, pure alcohol, and alcohol, is a toxic, volatile, flammable, and colourless liquid. Alcohol is the most commonly consumed alcoholic beverage in everyday life. EtOH is a common abbreviation for ethanol, where "Et" stands for the ethyl group (C2H5). Sugar fermentation to ethanol is one of the earliest organic reactions ever performed by humans; ethanol consumption has also been known for a very long time. This study aims to determine the histology of the liver in Wistar rats (Rattus norvegicus) by orally administering ethanol at a concentration of 50 percent. The method used in this study was an experimental study by looking at the histology of rat liver. Rats were divided into two groups, with seven rats each. Group 1 was given 50% ethanol orally for seven days, and group 2, as a control, was only given orally with distilled water. After seven days, the rats were slaughtered, and their livers were extracted for further histological preparations. In the histology results of group 1, the histological images of the livers of the rats P1, P2, P3, P4, P5, P6 and P7 were abnormal or damaged. In the presence of necrotic cells, oral administration of 50 percent alcohol causes damage to hepatocyte cells, as determined by the study's findings. However, in general, hepatocyte cell damage in the liver produces a score of 1.7, which indicates a change leading to cell damage.

Abstract

According to regulation number 722/MENKES/Per/IX/88 of the Minister of Health of the Republic of Indonesia, Rhodamine B is one of the dangerous dyes, and its use in food products is prohibited. Rhodamine B can cause adverse health effects including irritation, impaired liver function, and liver cancer. Although it has been banned, the use of Rhodamine B is still prevalent in the community's food supply, including shrimp paste. This can be observed in some of the shrimp pastes sold at the Ciroyom market in Bandung, which are bright red, uneven, and comprised of lumps. This study aims to determine the Rhodamine B content of shrimp paste sold at Ciroyom Market in Bandung, West Java, Indonesia. This research is descriptive in nature and employed a total sampling technique. Rhodamine B was analyzed in ten samples of commercially available red shrimp paste using a UV-Vis Spectrophotometer with a 565 nm wavelength. The results indicate that Rhodamine B was found in all samples, with concentrations ranging from 1.79 ppm to 3.999 ppm. Therefore, it can be concluded that widespread abuse of Rhodamine B in food ingredients persists among the residents of Bandung City, West Java, Indonesia.

Abstract

Health laboratory services or clinics can assist with patient recovery monitoring or diagnosis. The measurement of cholesterol levels is one of the frequent laboratory examinations. The CHOD-PAP enzymatic approach is the most used way to check your cholesterol levels. Plasma or serum is the test substance for cholesterol. Due to the presence of EDTA anticoagulant particles that will impact the test, the use of plasma is vulnerable to mixing with erythrocytes. This study used blood and plasma samples of EDTA anticoagulant to ascertain the variation in the outcomes of the average cholesterol levels. This research method compares two samples of EDTA anticoagulant—serum and plasma—in an analytical analysis using a comparative approach. According to the findings, there was a 1.12 percent difference between the average cholesterol levels in the serum sample (195.33 mg/dL) and the EDTA anticoagulant plasma sample (193.13 mg/dL). These findings indicate that there is no discernible difference in the cholesterol examination results obtained using EDTA anticoagulant-infused serum and plasma samples.

Abstract

The most used media for microbiological testing are nutrient agar because of their versatility. Nutrient Agar medium, meantime, is not cheap. This pushes researchers to find affordable, easily obtainable natural medium that have sources of nutrients for bacterial growth. One of them makes use of sunflower seeds, which have protein sources, raising the possibility that Sataphylococcus aureus and Escherichia coli can utilise them as a source of nourishment. The purpose of this study is to ascertain whether bacterial growth occurs and to assess the possibility of alternate media to sunflower seed agar as a medium for bacterial growth. The quadran streak method is being used in this descriptive investigation on the non-traditional media of sunflower seed agar and Nutrient Agar. Based on the research findings after observing the data, it was found that Escherichia coli can grow on sunflower seed agar as an alternative media, while Staphylococcus aureus cannot be grown because it is believed that sunflower seeds contain antimicrobial compounds like alkaloids, flavonoids, phytosterols, and tannins. The inference is that Escherichia coli can thrive on alternate media made of sunflower seed agar but Staphylococcus aureus cannot.

Abstract

The ability of a test to correctly (accurately) identify those who are ill and those who are not is known as diagnostic testing. Diagnostic tests are used to rate RT-PCR effectiveness (gen expert). Laboratory examination procedures are validated using diagnostic tests. By determining the values of sensitivity, specificity, positive predictive test, and negative predictive test, this study aims to determine the diagnostic usefulness of the RT-PCR instrument (gen expert). This study used an analytical approach and a comparative study methodology (comparative study), comparing the outcomes of an analysis using the gold standard technique, namely the microscopic and RT-PCR techniques (GeneXpert). To assess the data's sensitivity, specificity, positive predictive test, and negative predictive test values, a 2x2 table tubulation computation was used. The RT-PCR approach has an 85.3 percent sensitivity, a 100 percent specificity, a 100 percent positive predictive value, and a 92.3 percent negative predictive value. The study's findings indicate that the RT-PCR method (gen expert) has an 85.3 percent sensitivity value, a 100 percent specificity, a 100 percent positive predictive value, and a 92.3 percent negative predictive value.

Abstract

The platelet count and clotting time are typically examined in a test to determine platelet vulnerability. A normal platelet count often affects how quickly blood clots. A low platelet count will cause a prolonged clotting time, with the exception of some conditions such kidney failure, pulmonary embolism, acute CHD, haemophilia, and chronic liver disease. A normal clotting time value will be produced by a healthy platelet count. One anticoagulant drug that can be used to treat bleeding issues is heparin. In this study, patients who received heparin therapy and those who did not are contrasted in terms of platelet counts and bleeding times. This study employed an experiment to assess the platelet count and clotting time between heparin-treated individuals and patients receiving non-heparin medication. samples gathered by the process. According to the studies, patients on heparin had an average blood clotting time of 14.98 minutes as opposed to individuals not taking heparin therapy, who had an average blood clotting time of 7.43 minutes. Patients who did not receive heparin therapy had a mean platelet count of 165,250 cells/mm3, whereas those who did had a mean platelet count of 160,050 cells/mm3. The results of the study showed that there was no significant change in platelet count between patients getting heparin therapy and those receiving non-heparin therapy (sig 2-tailed: 0.311). Despite the significant variation in the value of clotting time between individuals taking heparin medication and those not (sig 2-tailed: 0.000). In this study, anticoagulants were found to have an impact on platelet quality but no impact on platelet quantity. The bleeding time examination variable should be included in future research, along with other variables, as a normal platelet count does not always translate into the same clotting time.

Abstract

The teaching scheduling system and value data processing used up to this point at SMK 1 Tulang Bawang Tengah are still not IT-based, which causes numerous errors, including schedules, changes to schedules that are inaccurate in real time, and the lengthy process of entering schedules, making it very difficult for staff. The schedule needs to be adequately organised, so we need an innovative method. The research that resulted in the development of this system was conducted using the waterfall methodology. The learning scheduling application and value data processing at SMK Negeri 1 Tulang Bawang Tengah were designed and developed utilising the waterfall technique, comprising four stages: analysis, design, coding, and testing. The results of black box testing applied to application testing show that the design matches expectations.
