PENGOLAHAN LIMBAH TEKSTIL (METHYLENE BLUE) MENGGUNAKAN ADSORBEN KARBON AKTIF KULIT MANGGIS (GARCINIA MANGOSTANA) TERAKTIVASI HIDROGEN PEROXIDE
Jurnal Inovasi Teknik Kimia
Vol 10
, No 4
(2025)
Textile wastewater is a major contributor to aquatic pollution because synthetic dyes such as Methylene Blue (MB) are toxic, persistent, and resistant to biodegradation. This study investigates the adsorption performance of activated carbon derived from mangosteen peel (Garcinia mangostana) activated with hydrogen peroxide (H₂O₂) for MB removal from aqueous solution. Activated carbon was prepared by carbonization at 850 °C, followed by chemical activation with diluted 50% H₂O₂. Adsorption tests...

This study developed a hybrid adsorbent derived from activated fly ash (FA) and humic acid (HA) for effective Mn²⁺ removal from aqueous solutions. Fly ash was activated using 1 M NaOH to increase its surface hydroxyl groups (≡Si–OH and ≡Al–OH) and enhance reactivity. The activated FA was then composited with HA, which contains abundant –COOH and –OH groups, forming an inorganic–organic hybrid with improved adsorption capability. The HA–FA composite with a 1:3 mass ratio exhibited the highest Mn²...

Project-Based Learning Effect on Improving Students’ Creative Thinking in Static Fluid Learning
Jurnal Penelitian Pembelajaran Fisika
Vol 16
, No 4
(2025)
The low creative thinking ability of students in understanding physics concepts, especially in static fluid material, is one of the problems that needs attention in the learning process. Therefore, this study aims to determine how the Project Based Learning (PjBL) learning model that uses a scientific approach affects students' ability to think creatively about static fluid material. The research method used is a quasi-experimental design with a Nonequivalent Control Group Design. The research s...

Virtual Reality Effect on Student Learning Outcomes in Nuclear Physics and Radioactivity Topics
Jurnal Penelitian Pembelajaran Fisika
Vol 16
, No 4
(2025)
Learning Nuclear Physics and Radioactivity is often perceived as difficult by student because the concepts are abstract, thus requiring learning media that can visualize these concepts more concretely. This study aims to analyze the effect of using Virtual Reality media on student’s learning outcomes in the topic of Nuclear Physics and Radioactivity. The research employed a Quasi Experimental method with a Nonequivalent Control Group Design. The subject were 33 12th grade students of Al Adzkar H...

ABSTRACT
Some Indonesian students aged 10–12 at the Indonesian Embassy in Malaysia's PNF Learning Center (PKBM PNF) still demonstrate low basic literacy skills. This condition is related to family backgrounds that do not have clear legal status due to unregistered marriages and the lack of valid citizenship documents. In addition, parental involvement in accompanying children's learning process at home is relatively low due to the demands of full-time work. This study aims to accompany and impro...
