Abstract

The matoa plant (Pometia pinnata) is known as a medicinal plant that has high antioxidant activity. Cigarette smoke produces free radicals and causes oxidative stress, a condition where the number of free radicals in the body exceeds the capacity to neutralize them. The aim of this study was to evaluate the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and histopathological features of rat’s lung exposed to cigarette smoke and matoa peels extract. The research method uses laboratory experimental studies using rats as research subjects. The design used was Randomized Posttest Only with Control Group Design. 24 male white rats of the wistar strain were divided into 6 groups: normal, negative control, positive control, and group I, II, III were given matoa peels extract 3, 6, and 12 mg/kgBW respectively and exposure to cigarette smoke for 14 days. After 14 days, MDA, SOD and histopathological picture of the rats' lungs will be compared based on the group. Data analysis was carried out using a one-way ANOVA test. The results showed that matoa peels extract could reduce MDA levels and increase SOD activity in rats exposed to cigarette smoke (p value <0.05). Group that is given matoa peels extract 12 mg/kgBW can reduce lung tissue damage.

Abstract

The presence of metals such as Hg, Cd, As, and Cr6+ in waters can cause health problems. Hg poisoning causes central nervous system symptoms, Cd poisoning can cause digestive problems and kidney disease, As poisoning can cause jaundice, kidney bleeding, and skin cancer and Cr6+ is highly corrosive and can cause cancer. This study aimed to measure the levels of Hg, Cd, As, and Cr6+ in water wells in Taman District, Sidoarjo Regency. In this study, the AAS method was used at 253.7 nm for Hg analysis; 228.8 nm for Cd analysis; 193.7 nm on As analysis, and UV-Vis spectrophotometric method at 530/540 nm for Cr(VI) analysis. The water wells in Taman District, Sidoarjo Regency have Hg, As, Cd, and Cr6+ levels of 0.0006 each; <0.002; <0.0002; and <0.013 mg/L (well water A) and <0.0006; <0.002; <0.0002; and <0.013 mg/L (well water B). Based on the chemical parameters, it can be concluded that the levels of Hg, As, Cd, and Cr6+ still meet the quality standards (maximum levels).

Abstract

Literacy and numeracy skills are cognitive learning outcomes measured in the Minimum Competency Assessment (AKM) and are part of the National Assessment (AN). This study aims to describe the literacy and numeracy achievement profile of junior high school students in terms of three aspects, namely content, cognitive processes, and context The descriptive quantitative approach method used in this research involved 141 class VIII junior high school students in North Aceh Regency and Lhokseumawe City through random sampling. Respondents are participants who took part in the 2021 National Assessment. The research instrument used was a question on literacy with 26 questions and numeracy with as many as 30 questions according to the grid and aspects of the AN that had been validated. The context of the questions is arranged in the form of personal, socio-cultural, and scientific. The distribution of the questions is in the form of 20% multiple-choice, 60% complex multiple-choice, 10% matching, 5% short answer or short answer, and 5% description. The results showedthe average percentage score of literacy ability was 43.87% with low criteria, meanwhile for numeracy skills, the average percentage score was 33.91% with very low criteria. These results indicate that students' literacy and numeracy skills in terms of each content need to be improved through the implementation of learning programs and the use of textbooks that lead to the improvement and development of literacy and numeracy skills.

Abstract

In this study, FTIR spectroscopy paired with PCA was utilized to differentiate biduri plants from different places. All biduri leaf samples from each location were then obtained for their FTIR spectrum in the wave number range of 4000-400 cm-1 and pretreated with the 1st derivative. The preprocessed spectrum was then examined using HCA and PCA chemometric methods; based on the HCA classification results, the biduri samples were divided into three groups, but the selected groups were unable to identify the biduri samples from the geothermal manifestation area. The PCA findings displayed in the plot scores then successfully classified the biduri leaf samples into four groups, with a total variance explained by 63% (PC1 44% and PC2 19%). This developed method can be used to correctly identify biduri plants originating from the geothermal manifestation area of Mount Seulawah Agam, allowing it to be concluded that environmental conditions in the geothermal manifestation area of Mount Seulawah Agam affect the content of secondary metabolites present in biduri plants, as evidenced by the PCA plot, which shows samples from geothermal and non-geothermal locations forming their respective groups.

Abstract

Clinacanthus nutans Lindau is known as the elephant trunk leaf which belongs to the Acanthaceae family. C. nutans can act as an antioxidant by reducing free radicals from the mitochondrial electron transport chain in the cell membrane. In this study, elephant trunk leaves will be studied regarding their content and antioxidant activity and their association with free radicals/Reactive Oxygen Species (ROS), which are compounds that are highly reactive. ROS can cause damage to cell integrity and functional cell disruption. Free radical reduction prevents lipid oxidation, which then reduces malondialdehyde (MDA) levels. By potentiating the antioxidant properties of Superoxide Dismutase (SOD) and reducing lipid peroxidation, C. nutans can reduce oxidative stress. The purpose of this study was to evaluate the effect of elephant trunk leaf extract on malondialdehyde and superoxide dismutase levels in rats with high activity. The research method used was laboratory experimental research with a Randomized Posttest Only with Control Group Design. In this study, 25 male white rats of the Wistar strain were divided into 5 groups: normal, negative control, and treatment I, II, III which were given elephant trunk leaf extract at successive doses of 50, 300, and 2000 mg/kg BW ( Weight). and high activity for 14 days. MDA measurements using a spectrophotometer and SOD using calorimetry were carried out after 14 days. The results showed that elephant trunk leaf extract reduced MDA levels and increased SOD activity in the blood plasma of rats induced by high activity (P value <0.05).
