Abstract

This research is motivated by the lack of understanding of the material by students, student boredom in learning, limited learning resources and the use of technology in learning that has not been maximized. The purpose of this study is to produce interactive learning media based on emaze using a contextual approach to integer material for class VII of SMP Negeri 4 Kubung. This type of research is research and development, using PLOOMP development consisting of three stages (Preliminary Research Phase, Design & Develop Prototype, Evaluation). The instruments used are teacher and student interview questionnaires, validation questionnaires consisting of language experts, media experts and material experts. The development of interactive learning media based on emaze goes through three stages. The first stage is preliminary analysis, namely: needs analysis, curriculum analysis, concept analysis, and analysis of student characteristics. The second stage: Creation and development, namely self-evaluation and expert validation. The third stage of evaluation is an assessment of whether interactive learning media based on emaze is valid for use. Based on the results of the validation of the material expert questionnaire 96.67%, media experts 83.88%, and language experts 88.00%, so that the average of the four validators is 89.51%. The results of this validation indicate that the developed emaze-Based Interactive Learning Media has been tested for quality and declared valid for use in the learning process.

Abstract

This study aims to develop a valid Local Instructional Theory (LIT) based on Realistic Mathematics Education (RME) on the topic of Applications of Derivatives. The LIT was developed to create a learning pathway tailored to students’ characteristics in understanding the concepts covered in the Applications of Derivatives material. The development model used in this study is a combination of Plomp’s development model and the development model proposed by Gravemeijer and Cobb. Validation was conducted by five experts, consisting of three content experts, one media expert, and one language expert. The validation instrument was a validation sheet covering content, presentation, language, and graphics. Data were analyzed using quantitative descriptive methods based on average validity scores and qualitative descriptive methods based on the validators’ suggestions. The validation results show that the developed LIT Book received a “very high” rating of 0.82. The Faculty Guide also received a “very high” rating of 0.82. Similarly, the Student Guide received a “very high” rating of 0.81. The results indicate that the LIT textbook, the Faculty Guide, and the Student Guide all based on RME and covering the topic of derivative applications are suitable for use as learning guides for faculty and students.

Abstract

The purpose of this study was to determine whether there is a significant effect of online learning perceptions on the learning outcomes of students of the Mathematics Education Study Program, FKIP UMMY Solok. The approach used is a quantitative approach with a correlational research method. The population in this study were students of the UMMY mathematics education study program in the 2021/2022 academic year. Sampling was carried out using purposive sampling technique. Data collection techniques using questionnaires and documentation. Data analysis techniques in quantitative research use statistics with SPSS 21.0. The results of the study obtained a simple linear regression equation of the effect of perceptions of online learning on learning outcomes, namely Y = 64.814 + 0.264 X. The results of the Fhitung test = 2.296 with a significance level of 0.144> 0.05 so it can be concluded that student perceptions of online learning do not significantly affect learning outcomes. The result of the coefficient of determination (KD) = 9.5% means that the perception of Mathematics Education study program students contributes to learning outcomes by 9.5%. So it can be concluded that the perception of online learning does not significantly affect the learning outcomes of students of the Mathematics Education Study Program, FKIP UMMY Solok.

Abstract

Kualitas air baku di SDN 008 Balikpapan Utara belum memenuhi standar air bersih karena tingginya kekeruhan dan keberadaan partikel koloid yang sulit disisihkan melalui filtrasi konvensional. Penelitian ini bertujuan menganalisis penerapan sistem elektrokoagulasi–filtrasi serta mengevaluasi dampak lingkungannya menggunakan pendekatan prospective life cycle assessment (pLCA). Penelitian dilakukan melalui pengujian elektrokoagulasi skala laboratorium yang dikembangkan menjadi rancangan skala lapangan berkapasitas 1.200 L. Analisis life cycle inventory (LCI) dilakukan berdasarkan konsumsi energi listrik, peluruhan anoda aluminium, pembentukan lumpur, dan emisi gas hidrogen, sedangkan penilaian dampak lingkungan menggunakan metode ReCiPe 2016 Midpoint. Hasil penelitian menunjukkan bahwa elektrokoagulasi mampu menurunkan kekeruhan dari 19,31 NTU menjadi 0,09 NTU, meningkatkan pH dari 5,66 menjadi 8,68, dan meningkatkan dissolved oxygen dari 1,70 mg/L menjadi 6,33 mg/L. Kebutuhan energi listrik sistem sebesar 2,88 kWh/siklus dengan konsumsi anoda aluminium sebesar 30,2 g/siklus. Hasil LCIA menunjukkan kategori dampak terbesar berasal dari agricultural land occupation dan climate change. Environmental hotspot utama sistem berasal dari konsumsi energi listrik dan penggunaan anoda aluminium sehingga diperlukan optimasi operasional untuk meningkatkan keberlanjutan sistem pengolahan air.
