Abstract

Perkembangan teknologi informasi telah mendorong banyak perusahaan untuk mengadopsi cloud computing sebagai solusi dalam meningkatkan efisiensi operasional dan manajemen data. Sistem berbasis cloud menawarkan berbagai keuntungan, seperti fleksibilitas, skalabilitas, dan pengurangan biaya infrastruktur, yang menjadikannya pilihan strategis bagi organisasi di berbagai sektor. Implementasi teknologi ini juga menghadapi tantangan, terutama dalam aspek keamanan data, integrasi sistem lama, serta kesiapan organisasi dalam melakukan transformasi digital. Penelitian ini bertujuan untuk menganalisis manfaat dan tantangan implementasi cloud computing dalam sistem informasi perusahaan serta memberikan rekomendasi strategi yang optimal untuk adopsi teknologi ini. Metode yang digunakan dalam penelitian ini adalah studi literatur dan analisis data sekunder dari berbagai sumber terpercaya, termasuk jurnal ilmiah, laporan industri, dan studi kasus perusahaan yang telah mengadopsi cloud computing. Hasil penelitian menunjukkan bahwa penggunaan cloud computing dapat meningkatkan efisiensi bisnis melalui pengurangan biaya operasional, peningkatan kolaborasi, serta optimalisasi pengelolaan data dan sumber daya perusahaan. Terdapat risiko yang perlu dikelola, seperti ancaman keamanan siber, ketergantungan pada penyedia layanan cloud, dan kebutuhan akan keterampilan teknis yang memadai di dalam organisasi. Oleh karena itu, perusahaan perlu menerapkan strategi adopsi yang komprehensif, termasuk pemilihan model cloud yang sesuai, penerapan kebijakan keamanan yang ketat, serta pengembangan kapasitas sumber daya manusia dalam mengelola teknologi ini.

Abstract

This study shows that the application of the Problem-Based Learning (PBL) learning model with a Culturally Responsive Teaching (CRT) approach can significantly improve the learning outcomes of students on the material of cultural diversity and local wisdom in class IVC SDN Pandanwangi 3. Learning that was originally teacher-centered and only relied on lectures and textbooks led to low active involvement of students and learning outcomes that were not optimal. This can be seen from the pre-cycle results which show that most students have not reached the Minimum Completeness Criteria (KKM). Through the application of the PBL model based on the CRT approach that accommodates students' cultural background and actively involves them in solving real problems, there is a significant improvement in learning outcomes. The percentage of learning completeness increased from 50% in cycle I to 82% in cycle II, with the average score increasing from 66.55 to 87.24. The findings prove that contextualized learning oriented to learners' culture can create a more inclusive, meaningful and effective learning experience in shaping 21st century skills and strengthening the learner profile of Pancasila.

Abstract

Research has been done on the Characteristics of Concrete with a Mix of Red Sand Grain Size 80 Mesh Post-burning. This study aims to determine the characteristics of concrete with a mixture of red sand grain size 80 Mesh Post-burning on the compressive strength, porosity and structure of the concrete. The test object is a cube of 15 cm x 15 cm x 15 cm with concrete quality K-225. In this study, variations in the composition of 80 mesh size red sand were made of 0%, 2%, 3% and 4%. After the concrete is 24 hours old, the mold is opened and given a sample code and treated in an immersion water bath. After going through an immersion period of 28 days, the concrete was burned in an oven with temperature variations of 400℃, 550℃, 700℃ and 850℃ and tested. The test methods used are compressive strength, porosity and Scanning Electron Microscope Energy Dispersive X-Ray (SEM-EDX). From the test results obtained the maximum average compressive strength obtained in concrete with a mixture of red sand of 4% with a temperature of 550℃. From the results of the porosity test, there was a decrease in the concrete with the addition of red sand by 4%. From the results of the SEM test, the concrete structure with a mixture of red sand has fewer and smaller cavities. From the results of the EDX test on concrete with a mixture of red sand, Calcium (Ca) and Stibium (Sb) elements have increased intensity when compared to normal concrete. From the XRD test results obtained elements - elements SiO2 (Silicon Oxide), Ca(OH)2 (Calcium Hydroxide) and CaO3 (Calcite) with the highest intensity is SiO2.
