Abstract

The role of community participation in Islamic educational institutions, particularly Madrasah Ibtidaiyah (MI), is increasingly recognized as essential for improving institutional quality and student outcomes. This study investigates the strategies implemented by MI Takhasus Darul Ulum Ngaliyan Semarang to enhance the quality of community involvement in school management. The aim is to explore how collaborative practices between the school and its surrounding community contribute to educational development. This qualitative research employs a case study approach supported by data from observations, interviews, and document analysis. The findings reveal that the madrasah has adopted inclusive strategies such as transparent communication, involvement in decision-making, utilization of local human resources, and open participation in both managerial and instructional activities. Community participation is manifested in both physical forms (e.g., infrastructure support, event committees) and non-physical forms (e.g., teaching, training, donations). These collaborative efforts have contributed to increased public trust, a 27% rise in student enrollment over two years, improved learning environments, and a strong sense of ownership among stakeholders. The study concludes that effective community engagement, when supported by visionary leadership and contextualized strategies, serves as a foundational pillar in building a resilient and sustainable educational ecosystem in Islamic schools. The model presented by MI Takhasus Darul Ulum offers practical insights for other Islamic educational institutions seeking to strengthen community-based governance

Abstract

Perkembangan teknologi digital mendorong industri perhotelan untuk mengadopsi sistem layanan yang lebih efisien dan aman, termasuk pada sistem akses kamar hotel. Penelitian ini bertujuan untuk menganalisis penerapan sistem akses kamar berbasis barcode yang terintegrasi dengan Internet of Things (IoT) serta dampaknya terhadap efisiensi operasional, keamanan, dan kualitas pelayanan hotel. Penelitian menggunakan pendekatan kualitatif deskriptif dengan teknik pengumpulan data melalui observasi, wawancara mendalam, dan dokumentasi terhadap manajer hotel, staf operasional, dan tamu hotel. Analisis data dilakukan melalui tahapan reduksi data, penyajian data, dan penarikan kesimpulan dengan triangulasi sumber dan teknik. Hasil penelitian menunjukkan bahwa sistem akses kamar berbasis barcode dan IoT mampu mempercepat proses check-in dan check-out, mengurangi ketergantungan pada kunci atau kartu akses konvensional, serta meningkatkan keamanan melalui penggunaan barcode unik dengan batas waktu tertentu dan pencatatan akses secara real-time. Selain itu, sistem ini mendukung pengelolaan data dan pengambilan keputusan manajerial, sehingga berpotensi meningkatkan daya saing hotel di era digital.

Abstract

Magnetic resonance imaging (MRI) provides rich anatomical contrast for brain tumor assessment, yet routine interpretation remains time-intensive and demands high precision. This work develops a pipeline for four-class brain MRI image classification (glioma, meningioma, pituitary tumor, and no tumor) by combining automated brain-region cropping, data augmentation, and transfer learning with EfficientNetB1. Experimental results demonstrate exceptional performance, achieving an overall accuracy of 0.99 (99%) on the test set. Specifically, the model reached an F1-score of 1.00 for the no tumor class, 0.99 for pituitary, and 0.98 for both glioma and meningioma classes. Beyond reporting numerical performance, the study utilizes Grad-CAM heatmaps to verify that predictions rely on clinically plausible regions rather than spurious background cues. These results indicate that an efficiency-oriented backbone, paired with systematic preprocessing, can achieve reliable and interpretable performance for brain tumor classification tasks.

Abstract

Reduction of thorium level by electrocoagulation process has been done. Electrocoagulation process is a method used in waste management, which is based on the use of electrodes with potential difference to produce coagulant. One of the process parameters in electrocoagulation is pH. This study aims to determine the effect of pH on the electrocoagulation process in order to lower the thorium level. The method used was batch electrocoagulation process in electrocoagulator tub of 22.5 × 14.5 × 20 cm dimension. The electrodes used were aluminum and copper of 20 × 20 cm2 size with active surface area of 250 cm2. Electrodes were installed in parallel with 1 cm distance between the electrodes. The electrocoagulation process was carried out with a working voltage of 2 V for 60 minutes. Sampling was done every 5-minute interval to prepare samples for subsequent thorium level analysis and pH measurement. The results show changes in pH value during the electrocoagulation process. Such changes result in the concentration change, which was indicated by coagulant separation efficiency. The separation efficiency of aluminum electrode was 98.06%, which was indicated by an increase in thorium level from the initial value of 439.274 ppm to 8.503 ppm within 5 minutes at a pH of 7.38. The copper electrode shows 96.35% efficiency in reducing thorium level from the initial value of 439.274 ppm to 16.015 ppm within 5 minutes at a pH of 7.29. Both electrodes used in the electrocoagulation processes show high separation efficiency and significant increase in pH values within 5 minutes, suggesting that the formation rate of coagulants is rapid during 5 minutes.

Abstract

Waste generated from the process of the industrial material development one of which waste containing uranium radioactive, can have negative impact on humans and the environment. In the present time, chemicals are still mostly use in radioactive waste treatment. To reduce pollutants with the use of chemicals is less efficient, because less environmentally friendly, take long time and costly. Therefore, a system of electrocoagulation process will be applied to decrease the activity of uranium from waste solution. The purpose of this study is to determine the efficiency of uranium activity decrease in waste water which is produced in the electrolysis process is conducted with voltage variations, the dwelling time, electrode spacing, and the waste inlet pH. The waste that will be treated has uranium contaminant levels of 500 mg/L. The experiment was conducted by a batch system with aluminum electrodes. Parameters affecting electrocoagulation process, such as voltage, time, distance electrode, and the pH have been studied and the best voltage optimization condition has been obtained of 12.50 V, a distance of 1 cm, pH 7, and in the processing time of 60 minutes efficiency of 97.20 % was obtained.
