Desain Dan Analisis Turbin Uap Aksial Pada Aplikasi Pembangkit Listrik Tenaga Uap Skala Rendah
No full textElectrification issues in remote areas of Indonesia remain a significant challenge, primarily due to infrastructure limitations and the high operational costs of fossil fuel-based power plants. This study aims to design and analyze a small-scale axial steam turbine (~1 kW) suitable for biomass-fueled steam power generation systems. The design process utilized SolidWorks 2022, supported by numerical simulations to evaluate structural strength, thermal efficiency, and fluid flow characteristics. Simulation results show that the maximum stress on components remains well below the material yield strength, while the system's estimated efficiency reaches 65–70%. The final design includes optimized configurations of blades, rotor, nozzle, and steam flow distribution. This study demonstrates that a CAD-based approach enables the development of efficient and technically feasible micro steam turbines for use in resource-constrained regions.Permasalahan elektrifikasi di daerah terpencil di Indonesia masih menjadi tantangan besar, terutama karena keterbatasan infrastruktur dan mahalnya biaya operasional pembangkit berbasis bahan bakar fosil.

No full textMarine data prediction plays a vital role in supporting decision-making in the field of marine environment and resources. However, the complexity of marine data, which is nonlinear and dynamic, is a significant challenge in producing accurate predictions. This study aims to explore the role of Long Short-Term Memory (LSTM) models in computer systems to predict marine data, focusing on Pearson Correlation analysis. The methods applied include collecting historical marine data, implementing LSTM models for prediction, and evaluating performance using metrics such as Mean Absolute Error (MAE). In addition, Pearson Correlation analysis is used to understand the relationship between variables in marine data. The results show that the LSTM model is able to produce predictions with a low error rate with a composition of training data and testing data of 80:20, resulting in Sea Surface Temperature (SST) = 0.0053, Sea Surface Salinity (SSS) = 0.0026, sea Surface Height (SSH) = 0.0061 and CHL-a = 0.0002 and shows a significant relationship between variables through Multivariate correlation analysis. This research contributes to the development of marine data-based prediction systems and provides implications for the world of marine resource research and management.

Islam And Anti-Corruption: Development Of Anti-Corruption Education Materials From A Religious Perspective
No full textCorruption is one of the most important variables in a country's decline. The Indonesian state established the Corruption Eradication Commission (KPK-Komisi Pemberantasan Korupsi) to address this. One of its roles is prevention, so the KPK has an anti-corruption education program. Unfortunately, this program has not integrated religious values, even though Indonesia is a religious and predominantly Muslim society. This article examines anti-corruption education from an Islamic perspective. This study seeks to integrate anti-corruption education with an Islamic perspective. This study uses a thematic-analytical method whose primary source is the Quran, interpreted from various commentaries. The findings show that, in substance, the Qur'an has taught us not to commit corruption. Phrases found in the Qur'an whose meaning is commensurate with corruption are 'eating other people's property unlawfully' (akl amwal al-nas bi-al-batil), 'eating illegally' (akl al-suht), and bribing judges (al-idla' ila-al-hukkam). This study further shows that corruption falls into the category of unlawful taking away other people's rights, while bribery is one of the doors to this unjust act. Therefore, corruption is a grave sin that will have serious consequences hereafter. The findings of this study can further contribute to the development of anti-corruption education from an Islamic perspective
The Effect of Tahfidz Learning Programme Participation on Learning Motivation and Islamic Religious Education Learning Achievement
No full textThis study aims to examine the effect of santri participation in the tahfidz learning program on learning motivation and learning outcomes of Islamic Religious Education (PAI) at Rumah Tahfidz Zainal Muhibbin. The background of this study rests on the importance of integrating spiritual values in Islamic Education learning strategies that are not only cognitive, but also affective. This study used a quantitative approach with a correlational design. A sample of 60 students was purposively selected with the criteria of participating in the tahfidz program for at least one semester and having an odd semester PAI report card in the 2024/2025 school year. The instruments used include a Likert scale-based learning motivation questionnaire and PAI score documentation. The results of statistical analysis showed that there was a significant positive relationship between participation in the tahfidz program and learning motivation (r = 0.648; p < 0.05), as well as between participation in tahfidz and PAI learning outcomes (r = 0.611; p < 0.05). Simple regression analysis showed that the tahfidz program contributed 42% to the variation in learning motivation and 37.3% to PAI academic achievement. This finding indicates that participation in tahfidz not only builds religious character, but also has a real impact on students' academic performance. This study confirms the importance of tahfidz program as an integrative pedagogical and spiritual approach in Islamic education learning. It is recommended that Islamic educational institutions develop a curriculum that makes tahfidz as part of strengthening the quality of value-based learning
