Abstract

The purpose of this study was to analyze the feasibility of the items of the four-tier multiple-choice test immune system instrument that had been developed. The development of the instrument using the Treagust (1988) model, namely defining content, collecting student misconceptions information, and developing a diagnostic test. A total of 25 items have been developed. The results of the instrument development were tested on 142 students of grade XI from several high schools in Surakarta who were selected by simple random sampling. The data analysis technique was performed using Rasch analysis in the Winstep application. The results of the construct validity test showed items number 5, 7, and 9 did not fit the validity standards. The reliability test shows that the value of Cronbach Alpha reliability is bad (n = 0.51), the value of the reliability item is special (no = 0.97), the value of person reliability is sufficient (n = 0.68), the value of person separation is weak (n = 1.44), and the item separation value is special (n = 5.38). The person discrimination test showed student 056P31 has the highest ability and student 098P51 has the lowest ability. The item discrimination test shows item number 1 is the best item and the bad item is number 14. The item difficulty analysis showed less proportionality because there were too many items in the easy and difficult categories. An expansion of the sample is needed to see a more comprehensive and diverse range of responses to instruments.

Abstract

Background: Indonesia's biodiverse microalgae, numbering 2060 species, thrive in diverse environments, offering potential in pharmaceuticals, cosmetics, fuel, and heavy metal bioremediation. Lead pollution from mining poses risks, prompting stringent government contamination limits. Microalgae-based bioremediation, notably Chlamydomonas reinhardtii and Chlorella vulgaris removing up to 90% of lead, suggests further exploring Indonesia's microalgae diversity. Methods:  Data sourcing (2013-2023) employed Google and Google Scholar using specific keyword combinations across Indonesian provinces. Seventy-eight sources underwent analysis and visualization via Microsoft Excel 2021. Results: Microalgae's potential as lead bioremediation was explored across classes like Chlorophyceae, Cyanophyceae, and Bacillariophyceae. Chlorophyceae, exemplified by Chlorella and Scenedesmus, exhibit varied cell sizes and complex cell walls, aiding metal ion binding. Cyanophyceae like Cyanospira capsulata and N. commune synthesize diverse EPS compositions, indicating their potential in lead remediation. Conclusions: Indonesia's microalgae diversity across habitats, especially in the Chlorophyceae and Cyanophyceae classes, suggests a significant role in lead bioremediation. Their adaptability and diverse compositions highlight their potential for sustainable practices in combatting environmental lead contamination.

Abstract

Higher education institutions must implement appropriate evaluation and strategy determination to support their role in establishing a Sustainable Campus. This study aims to (1) evaluate the implementation of the sustainable campus program at Universitas Sebelas Maret (UNS), (2) analyze the dominance of internal (IFAS) and external (EFAS) factors at UNS, and (3) formulate strategies that UNS should implement to strengthen its sustainable campus initiatives-the implementation evaluation utilized data from the UNS GreenMetric report. The factor dominance analysis employed IFAS and EFAS, while the strategy formulation used SWOT-TOWS analysis. The findings indicate that UNS has stagnant scores in the Water (WR) and Transportation (TR) indicators. Furthermore, UNS’s strengths lie in its open space availability and sustainable academic programs, though this advantage is hindered by limited budget allocation for toxic waste management. Based on the analysis, the recommended course of action for UNS is the Strengths-Opportunities (SO) strategy. The implementation of this SO strategy is necessary for UNS to advance its role as a sustainable campus successfully. This study implies that the integration of sustainability performance evaluation using UI GreenMetric data with IFAS, EFAS, and SWOT-TOWS analysis provides a structured basis for identifying dominant strategic conditions and formulating strength-oriented strategies to improve sustainable campus implementation at Universitas Sebelas Maret. The study implies that Universitas Sebelas Maret should utilize sustainability assessment results as strategic inputs rather than merely as reporting tools, enabling more targeted interventions in critical areas such as water and transportation management. These findings may further contribute to the development of management strategies derived from SWOT and TOWS analyses in other universities across Indonesia.

Abstract

Thalassemia is an autosomal recessive genetic disorder that remains a significant public health concern in Indonesia; consequently, early detection of carriers is crucial to prevent the birth of children with thalassemia major. This study aims to analyze the risk of thalassemia among Biology students at the Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Riau, utilizing a simplified laboratory screening approach. The research involved 30 students who participated in genetic risk questionnaires, hemoglobin level assessments using digital hemometers, and erythrocyte counts via hemocytometers. The findings revealed a questionnaire risk score of 0.07 (categorized as very low), a mean hemoglobin level of 12.73 g/dL, and an erythrocyte count of 5.22 million cells/µL, both of which fall within normal physiological ranges. These results indicate that the risk of thalassemia among Biology students at FMIPA Universitas Riau is remarkably low. Simple screening through questionnaires, hemoglobin levels, and erythrocyte counts can serve as an effective method for both educational purposes and the preliminary screening of thalassemia carrier risk in students.
