Abstract

The aim of this research is to measure the effectiveness of using the "Saya Ingin Bertanya" application in improving understanding of learning material in class X SMA AL-WASHLIYAH 1 MEDAN. This research uses an experimental method, which aims to determine the effect of the intervention imposed on research subjects. Data collection was carried out using several techniques, namely class randomization, pre-test and post-test, questionnaires, and monitoring application activity. Data analysis in this research involved descriptive statistical tests, independent sample t-two tests, and simple linear regression analysis. The “Saya Ingin Bertanya” application is designed to help students ask questions anonymously and get answers to their questions in real-time. The main features of this application include a question and answer forum but the identity is unknown, asking questions on topics being studied and topics to be studied, asking questions outside the learning topic and learning resources that are uploaded by the teacher and can be accessed directly by students. The results of the analysis show that there is a significant difference in increasing understanding of the material between the control group and the experimental group after the intervention. The significance value obtained (p < 0.05) shows that the difference between the two groups did not occur by chance, but was significant.

Abstract

Penelitian ini bertujuan untuk menganalisis potensi Bahasa Indonesia dalam konteks global, menyoroti peluang dan tantangan yang terkait. Dengan mempertimbangkan perkembangan teknologi dan tren internasional, kami mengeksplorasi bagaimana Bahasa Indonesia dapat menjadi aset penting dalam berbagai bidang seperti bisnis, pendidikan, dan kebudayaan. Penelitian ini menggunakan literature review atau desain studi pustaka. Fokus utama pada penelitian ini adalah menggali wawasan yang mendalam melalui analisis naratif dan deskriptif. Melalui analisis, artikel ini berupaya memperkuat pemahaman tentang posisi Bahasa Indonesia dalam lingkungan multibahasa global, serta memberikan pandangan terhadap langkah-langkah yang dapat diambil untuk memanfaatkan potensi penuhnya sambil mengatasi tantangan yang muncul. Hasilnya menunjukkan bahwa Bahasa Indonesia memiliki potensi besar untuk berkembang di panggung global. Namun, terdapat berbagai tantangan yang harus dihadapi dan diatasi oleh masyarakat dan pemerintah Indonesia, termasuk tantangan terkait dengan pengembangan kurikulum, promosi internasional, dan kebijakan bahasa. Implikasi praktis dari temuan ini meliputi perlunya strategi komunikasi yang lebih efektif dan dukungan yang kuat dari berbagai pemangku kepentingan untuk memajukan peran Bahasa Indonesia di panggung global.

Abstract

This study investigates the growth response of mung bean Vigna radiata L. and spinach Amaranthus hybridus L. under controlled acidic neutral and alkaline environments across a wide pH gradient from pH 3 to pH 14. The work provides a comparative assessment of two species with distinct physiological characteristics to clarify how hydrogen ion concentration shapes vegetative development. The novelty of this study lies in its direct evaluation of extreme pH conditions using a uniform experimental design that allows both species to be examined under identical chemical exposure, enabling a clear contrast of tolerance thresholds. Plant height was recorded daily for 13 days to capture early stage vegetative dynamics. Both species exhibited their highest stability near pH 7 while severe deviations from neutrality reduced growth through nutrient imbalance and physiological stress. Mung bean showed moderate tolerance at pH 9.5 whereas spinach displayed enhanced performance within mild alkalinity. Strong acidity and strong alkalinity produced structural damage in both species. The findings highlight the critical role of soil pH in plant performance and provide foundational insight into species specific tolerance ranges that can support more informed management of crops grown in chemically variable environments.
