PENGARUH KONSENTRASI KATALIS KOH, MgO DAN CaO PADA PEMBUATAN BIODIESEL DENGAN PROSES TRANSESTERIFIKASI
Jurnal Inovasi Teknik Kimia
Vol 10
, No 2
(2025)
Biodiesel dapat didefinisikan sebagai ester monoalkil yang dapat dihasilkan dari bahan alami yang terbarukan seperti minyak nabati dan hewani. Bahan bakar ini berpotensi untuk digunakan sebagai bahan bakar alternatif pengganti solar karena sifatnya yang mirip. Selain itu, biodiesel yang berasal dari minyak nabati merupakan bahan bakar terbarukan (renewable), mudah ditangani, tidak menghasilkan polutan berbahaya bagi lingkungan (tidak beracun), mudah terurai secara alami, emisi berbahaya dari pem...

Evaluating Compressed Sensing Matrix Techniques: A Comparative Study of PCA and Conventional Methods
Advance Sustainable Science, Engineering and Technology (ASSET)
Vol 7
, No 2
(2025)
This research examines the performance of various compressed sensing matrix techniques, with a focus on Principal Component Analysis (PCA) compared to conventional methods. By applying these techniques to a range of high-dimensional datasets, we assess their effectiveness in reducing data dimensionality while preserving essential information. Our results demonstrate that PCA consistently outperforms traditional methods in terms of both accuracy and computational efficiency. These findings have s...

Teaching at The Right Level Approach with the Problem Based Learning Model Effect on Physics Problem Solving Ability
Jurnal Penelitian Pembelajaran Fisika
Vol 16
, No 2
(2025)
Physics lessons are among the most interesting because they relate to actual events. Physics learning requires an independent learning process that equips students with problem-solving skills. This study examines how the Problem-based Learning (PBL) model and the Teaching at the Right Level (TaRL) strategy affect the resolution of physics issues involving momentum and impulse topics. There are 375 grade XI students participating in a quasi-experiment with a non-equivalent control group design. T...
