Abstract

Cadmium (Cd) which accumulates in the body for a long time can damage human organs such as the respiratory tract, reproductive organs, liver, and kidneys. However, many smokers ignore this, so laboratory evidence is needed to advise smokers. This study analyzed the levels of cadmium (Cd) in the urine of smokers in Bangoan Village, Tulungagung District. The research method used is descriptive analytics. The research sample consisted of 15 smokers obtained through random sampling from 15 cafes in Bangoan Village, Tulungagung Regency. The research instrument was a urine examination result sheet. Urine samples were examined with an Atomic Absorption Spectrophotometer (AAS). The data analysis technique was carried out using quantitative descriptive. The results showed that 8 (53%) smokers had normal cadmium levels, and 7 (47%) other smokers had abnormal cadmium levels with the lowest level being 0.503 µg/L and the highest level being 83.892 µg/L. The community is expected to reduce cigarette consumption and avoid exposure to cigarette smoke in the surrounding environment in order to reduce organ damage.

Abstract

Obesity is excessive fat accumulation in the body. Continuous obesity and excessive food intake can cause metabolic system disorders in the form of hypercholesterolemia. Analysis of cholesterol and triglyceride levels in obese patients needs to be carried out to assist them in making healthier lifestyle changes. This study aims to analyze cholesterol and triglyceride levels in obese patients. The research method used is experimental with a laboratory approach. The samples to be analyzed were 20 obese people obtained by purposive sampling technique in the Tulungagung area. The research instruments used were height and weight check sheets and cholesterol and triglyceride test results sheets. Research data analysis technique by examining cholesterol and triglyceride levels using a MicroLab C-300 spectrophotometer and will be analyzed descriptively quantitatively. The results showed that 15 patients had normal cholesterol levels (75%) with criteria <200 mg/dl and 5 patients had high cholesterol levels (25%) with criteria >200 mg/dl, while there were 17 patients with normal triglyceride levels (85 %) with criteria <150 mg/dl and 3 patients had high triglyceride levels (15%) with criteria >150 mg/dl. The conclusion of this study is that people who are obese do not necessarily have high cholesterol and triglyceride levels. However, when a person weighs > 80 kg, it is recommended to start paying attention to a healthier lifestyle.

Abstract

Environmental damage is the effect of negative impacts on the natural environment caused by human activities. The importance of empowering knowledge and caring for the environment in students so that they can participate in protecting and preserving the environment. The purpose of this research is to describe literacy and environmental awareness to preserve the environment and the relationship between environmental literacy and awareness to preserve the environment. This research method uses descriptive quantitative research and research techniques using a questionnaire with a sample of 50 students using a random sampling technique in the Adiwiyata school program, especially junior high school students. The instruments used were student characteristic sheets, environmental literacy, and environmental awareness questionnaires. Research data were analyzed descriptively and the relationship between literacy and environmental awareness used correlation analysis using SPSS. The results showed that students' environmental literacy was classified as moderate to high with a score of 1.6 – 3.20. The average value of students' environmental awareness is 73% indicating that students have a caring attitude toward environmental problems. Environmental attitudes and environmental awareness also have a significant relationship (sig <0.05). Through environmental literacy and awareness, students will have the potential to protect and preserve the environment.

Abstract

Science Process Skills (SPS) need to be developed to improve teacher quality in teaching. The existence of the Covid-19 pandemic caused Biology teachers to be unable to carry out practicums so the SPS were helpless. This study aims to analyze the science process skills of biology teacher candidates in vertebrate zoology courses. The research method used is descriptive quantitative through survey techniques. This research was conducted at the PGRI Ronggolawe University and involved 21 participants. This study uses an instrument in the form of an observation sheet to measure scientific process skills. The SPS indicators that are measured are the skills of observing, measuring, compiling tables, and obtaining and processing data. The data obtained is then interpreted into very high, high, low, and very low categories. The percentage of students in each category is then calculated as a map of their science process skills through analysis of quantitative descriptive data. The results showed that 65.5% of prospective biology teachers had SPS scores that were in the very high, high, low, and very low categories. 7.5% has an SPS value which is included in the very low category. In general, biology teacher candidates tend to have very high levels of competency in performing science process skills.

Abstract

The main bacteria that cause infection in humans is Staphylococcus aureus. Efforts to prevent infectious diseases caused by bacteria can be made by using plant parts that have medicinal potential. One part of the plant that needs to be explored for its potential is the skin of shallot bulbs (Allium ascalonicum L.). This research aimed to determine the effect of red onion skin extract on the growth of S. aureus bacteria. The research design is experimental. The samples in this study were 1 kg of red onion skin and a bacterial sub-culture of S. aureus ATCC: 25923. Extraction was carried out using the maceration method using 96% ethanol solvent and evaporated using a rotary evaporator and water bath. The antibacterial test was carried out by administering 30 µg chloramphenicol (positive control), sterile distilled water (negative control), and red onion skin extract with concentrations of 60%, 65%, 70%, and 75% with 3 repetitions. All treatments were given to S. aureus at 30 µL each using the Kirby-Baeur method. The research instrument was an observation sheet of the diameter of the inhibition zone. Data analysis used One-Way ANOVA. The results of this study show that ethanol extract of red onion skin with concentrations of 60%, 65%, 70%, and 75% was able to produce S. aureus inhibition zone diameters of 3.5 mm, 4 mm, 4.2 mm, and 4.3 mm. The results of the One-Way ANOVA test showed a significance value of 0.15 (sig>0.05), not proven to be able to significantly inhibit the growth of S. aureus. The conclusion shows that red onion skin extract as an antibacterial is not able to significantly inhibit the growth of S. aureus.
