Abstract

Blood is a thick liquid that is in the blood vessels of the body, which is red because it contains hemoglobin to circulate oxygen and nutrients throughout the body. If blood comes out of the body due to sharp or blunt blows, either intentionally or unintentionally, it will end up on your clothes. Clothing is made from fabric composed of fibers, generally in the form of denim, cotton and polyester. This research was conducted to determine the color changes that occur in blood spots based on storage times of 0 days, 15 days and 30 days and to determine the area of ​​blood spots that form on denim, cotton and polyester fabrics. The method used in this research is measuring the diameter and observing the color changes that occur. The research design used in this research was (RAL) a completely randomized design with repetition 3 times. The results of the research showed that there were color changes that occurred from fresh red, dark brown, and light brown. Meanwhile, the area of ​​fabric obtained from denim fabric has the smallest area compared to cotton and polyester fabrics. However, the polyester fabric has black stains around it.

Abstract

ABSTRACT Asthma is a disease caused by chronic inflammation of the respiratory tract, which causes shortness of breath and difficulty breathing. This disease arises due to genetic factors or heredity. Genetic diseases may not be inherited again in the next generation, but can recur due to several risk factors that trigger asthma. This study aims to analyze the relationship between hereditary history and risk factors on the incidence of asthma. Sampling was carried out using a purposive sampling technique, data collection was carried out by measuring the variables studied using questionnaires and interviews, and data analysis was carried out using correspondence analysis. The results of the study show that not all asthma patients have a family history of asthma, and non-genetic risk factors that cause asthma recurrence consist of age, gender, body mass index (BMI), home location, smoking habits, and environmental factors consisting of fatigue, cold weather, dust allergies, mental influences, air pollution, animal dander allergies, and food allergies. Keywords: Allergies, asthma, genetics, gender, shortness of breath, age
