Promotion and provision of information on subsidized housing for low-income communities (MBR) is still carried out conventionally, such as throught brochures, banners or exhibitions. This method is considered less effective in reaching the wider community, especially the younger generation who are more familiar with digital technology. This research aims to design and create a web-based information system for sales promotion of subsidized housing at Mutiara Gerden Housing. This system is expecte...

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...

Unveiling the Link Between Numeracy Skills and Self-Efficacy: A Study on Physics Learning Through AKM Assessments
Jurnal Penelitian Pembelajaran Fisika
Vol 16
, No 4
(2025)
This study explores the relationship between numeracy skills and self-efficacy among grade 10 students within the context of the Minimum Competency Assessment (AKM) in physics, focusing on linear and parabolic motion. Employing a quantitative descriptive design, the research involved 140 students from a public high school in Bekasi, Indonesia. Instruments included a numeracy test comprising 17 AKM-based physics questions and a self-efficacy questionnaire adapted from Bandura's framework, coverin...

Problem Based Learning Effect Using the TaRL Approach on Problem-Solving Skills in Global Warming Topic
Jurnal Penelitian Pembelajaran Fisika
Vol 16
, No 4
(2025)
Physics learning is often considered difficult because students are unable to relate concepts to real-world problems they encounter. This condition results in low problem-solving skills among students, especially on contextual topics such as global warming. This study aims to determine the effect of the Problem Based Learning (PBL) model with the Teaching at the Right Level (TaRL) approach on students' problem-solving skills in global warming material. The research method used was quantitative w...

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...
