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.
