Credit approval prediction is one of the critical challenges in the financial industry, where the accuracy and efficiency of credit decision-making can significantly affect business risk. This study proposes an outlier detection method using the Gaussian Mixture Model (GMM) combined with Extreme Gradient Boosting (XGBoost) to improve prediction accuracy. GMM is used to detect outliers with a probabilistic approach, allowing for finer-grained anomaly identification compared to distance- or densit...

Purple corn is one of the corn varieties that is being developed by Indonesia as a form of food diversification. The purple color of corn is produced by the high presence of anthocyanins so it can provide health benefits such as antioxidant, anti-inflammatory, mutagenic, anti-cancer and anti-angiogenesis. To ensure that the bioactive components are not damaged, extraction is carried out in stages by applying the maceration method using a polar solvent with the correct ethanol content of 96%. Apa...

(2024)
ABSTRAK
Indonesia sebagai negara kepulauan sangat bergantung pada transportasi kapal laut untuk menghubungkan antar pulau. Pada proses perencanaan konstruksi kapal, pemilihan material lambung yang terbaik sangat penting untuk menghadapi masalah korosi. Paduan aluminium dikenal memiliki ketahanan korosi yang baik, sehingga sering dipilih untuk aplikasi di lingkungan korosif, seperti laut. Paduan seri 5xxx, khususnya Aluminium 5083 dan 5052, umum digunakan dalam industri pembuatan kapal karena kar...

Jurnal Penelitian Pembelajaran Fisika
Vol 15
, No 4
(2024)
The problem in this study is the lack of questioning skills based on cognitive process dimensions and knowledge dimensions. This research aims to analyze questioning skills through students' written work using the revised Bloom's Taxonomy framework, specifically the cognitive process and knowledge dimensions. The participants were 32 students (15 males and 17 females) from class XI MIPA 3 at a high school in Bandung. This descriptive study employed documentation analysis using Google Forms for i...

Development of E-Modules Based on Socio-Scientific Issues to Improve Students' Science Literacy Skills on Temperature and Heat Materials
Jurnal Penelitian Pembelajaran Fisika
Vol 15
, No 4
(2024)
E-modules on temperature and heat material have been developed in several studies, but there are still problems. The problem is that it does not facilitate students to practice science literacy skills so it is still relatively low. This research aims to minimize these problems by developing e-modules based on socio-scientific issues to improve students' science literacy skills in temperature and heat materials. The method used is Research and Development with a 4D development design consisting o...
