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

SIPRIMA (Sinergi Promotif dan Preventif untuk Masyarakat Sehat) merupakan program pengabdian masyarakat yang bertujuan meningkatkan literasi kesehatan ibu hamil serta memperkuat keterlibatan keluarga dalam perawatan kehamilan. Kegiatan ini mengintegrasikan Gebyar Posyandu dengan Kelas Ibu Hamil berbasis family oriented, meliputi edukasi kesehatan kehamilan, teknik akupresur, dan prenatal gentle yoga.Desain kegiatan menggunakan one group pretest–posttest yang melibatkan 10 ibu hamil di Kelurahan Balai Gadang, Kota Padang. Intervensi dilakukan melalui penyuluhan, demonstrasi, dan praktik langsung. Pengetahuan ibu diukur menggunakan kuesioner sebelum dan setelah intervensi.Hasil menunjukkan peningkatan skor pengetahuan akupresur dari 72 menjadi 76, meskipun belum signifikan secara statistik (p=0,10). Sebaliknya, pengetahuan prenatal gentle yoga meningkat signifikan dari 83 menjadi 91 (p=0,02).Program ini berkontribusi dalam meningkatkan pemahaman ibu hamil, mendorong partisipasi keluarga, serta memperkuat peran Posyandu sebagai pusat layanan promotif–preventif berbasis komunitas. SIPRIMA direkomendasikan untuk diintegrasikan sebagai kegiatan rutin Posyandu dalam mendukung kesehatan ibu hamil.

Abstract

The Core Tax Administration System (CTAS), launched in January 2024, marks a major step in Indonesia’s digital tax reform. This study examines its opportunities and challenges in transforming tax services. Using a qualitative approach through literature review and content analysis of secondary data, particularly media reports and public documents, the research finds that CTAS has strong potential to improve efficiency, transparency, and integration of tax administration. However, implementation has been hindered by technical disruptions, uneven infrastructure, limited human resource readiness, and low digital literacy among taxpayers. The accelerated rollout without extensive pilot testing also led to operational issues and declining user trust. To address these obstacles, the study highlights the need for continuous system evaluation, capacity building for tax officials, and comprehensive taxpayer education. Ensuring inclusiveness and reliability will be crucial for CTAS to function not only as a technological innovation but also as a foundation for sustainable tax service transformation.

Abstract

One of the efforts to improve the quality of midwives in order to be able to provide maternal and neonatal services quickly and appropriately by applying Evidence-Based Practice (EBP) to midwifery students. Considering that EBP is a concept in the academic field of midwifery is considered the backbone of quality clinical care. This study aims to determine the practice and use of EBP in midwifery students in the city of Padang, West Sumatra. This study uses a cross-sectional method, uses an online questionnaire Google Forms and is distributed to students through social media to midwifery students whose campus is located in Padang City. The results of the study were from 83 respondents, who had a good level of knowledge in the use of EBP as many as 9 respondents (10.8%), 58 respondents (69.9%), and 16 respondents (19.3%) with a low level of knowledge. As for student attitudes, 49 respondents (59%) had a positive attitude and 34 respondents (41%) had a less supportive attitude in implementing EBP, for practical readiness as many as 14 respondents (16.9%) had high readiness, 60 respondents (72.3%) were in the category of quite ready, and 9 respondents (10.8%) were in the category of not ready in the implementation of EBP. So that it can be concluded that the level of knowledge of midwifery students in the city of Padang in implementing EBP is good and students have a positive attitude and an overview of the readiness of student practice in the category is quite ready.

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.
