Get PDFThis study aimed to analyze the interaction between learning motivation and problem-solving skills in the context of Social Sciences (IPS) learning at SMPN 8 Cimahi. Adopting a quantitative approach through a 2^3 factorial experimental design, this research involved 60 students divided into an experimental group (using Problem-Based Learning - PBL) and a control group (using Inquiry Learning). Data was collected through observation, documentation, pretest-posttest, and questionnaires, then analyzed using descriptive and inferential statistics (One-Way ANOVA) with SPSS 26.0. The results showed a significant increase in problem-solving skills in the PBL group compared to the Inquiry group, especially due to the interaction with student learning motivation. Descriptively, the average normalized gain score of the PBL group (0.8424) was superior to that of the Inquiry group (0.7147). The One-Way ANOVA test confirmed significant differences in problem-solving skill improvement for both learning groups (PBL: F=44.220, sig<0.000; Inquiry: F=4.866, sig<0.016), with effects varying based on motivation levels. Furthermore, the interaction effect test (F=4.410, sig=0.022) confirmed a combined influence between learning methods and student motivation. These findings conclude that PBL is more effective in enhancing student engagement and problem-solving skills, while also emphasizing the importance of considering teaching methods and student motivation levels when designing learning activities

Get PDFThis study aims to implement a contextual learning approach based on the Riyaya Unduh-Unduh tradition as a strengthening of global diversity character in 8th-grade junior high school students. The Riyaya Unduh-Unduh tradition is a unique tradition from the Javanese Christian Church (GKJW) Mojowarno Jombang that reflects values of gratitude, tolerance, mutual cooperation, and appreciation of diversity. This research employs a mixed methods approach with sequential exploratory design combining ethnographic studies, Classroom Action Research (CAR), and evaluative research. The research subjects involved 32 students from 8th grade at SMP Pancasila Mojowarno, Jombang Regency. Data were collected through participatory observation, in-depth interviews, documentation, global diversity attitude questionnaires, plurality concept comprehension tests, and student reflective journals. The results show that the contextual learning approach based on the Riyaya Unduh-Unduh tradition is effective in improving students' understanding of plurality concepts with an N-gain of 0.72 (high category) and global diversity attitudes across five dimensions with significant score improvements. The developed learning model consists of five stages: context exploration, concept elaboration, project collaboration, critical reflection, and concrete action. The implementation of CAR in two cycles showed increased enthusiasm and student ability to identify diversity values. This research contributes to the development of global diversity character education that aligns with the Merdeka Curriculum and Pancasila Student Profile Program
Meningkatkan Imajinasi Sejarah melalui Penggunaan Novel dalam Pembelajaran Sejarah
Get PDFThis study aims to examine the influence of using the historical novel Kurir-Kurir Kemerdekaan as a learning source on high school students’ historical imagination. Historical imagination includes the ability to re-enact past events, interpret their meaning reflectively, and understand the emotions and motivations of historical actors within their temporal context. A quasi-experimental design with a non-equivalent pretest–posttest group approach was employed. Two classes participated: the experimental group, which used a historical novel, and the control group, which engaged in a project-based shadow puppet performance. Results showed that the experimental group experienced a statistically significant improvement (p < 0.001), from an average score of 25.42 to 52.33, with an N-Gain of 35.56, higher than the control group’s 22.86. Indicator-based analysis revealed the highest gain in empathy (0.39), followed by interpretation (interrogation) at 0.28, and narrative reconstruction (re-enacting) at 0.24. These findings demonstrate that historical novel-based instruction is more effective in enhancing students’ affective and reflective engagement with history. The narrative elements within novels help students form emotional and cognitive connections with the past and interpret historical events in a more humanistic manner
Menilik Efek Disruptif Penggunaan Teknologi Artificial Intelligence dalam Pembelajaran Sejarah
Get PDFThe development of Artificial Intelligence (AI) has brought significant changes to the educational paradigm, including history learning, which is now shifting from a conventional model to a more adaptive and interactive digital system. This study aims to analyze the positive impacts and disruptive effects of AI implementation in history education while formulating mitigation strategies to balance technological advancement with humanistic values. Using a literature study method and a descriptive-analytical approach, the findings indicate that AI has the potential to enrich history learning through personalized learning, digital visualization based on VR and AR, and data analytics that assist teachers in understanding students’ needs more deeply. However, challenges arise in the form of shifting teacher roles, dependency on algorithmic systems, and ethical as well as privacy concerns. Therefore, strategies such as strengthening teachers’ digital literacy, implementing hybrid learning models that integrate AI with human interaction, and establishing ethical policies focusing on students’ rights protection are essential. Thus, the application of AI should be positioned as a means to reinforce the humanistic dimension and reflective character of learners, rather than merely serving as a tool for learning efficiency in the digital era

Pengaruh Variasi Suhu Kalsinasi terhadap Struktur Kristal dan Sifat Mekanik Hidroksiapatit dari Limbah Cangkang Kerang Mutiara
Get PDFHydroxyapatite (HAp is widely known as a promising biomaterial because its chemical composition closely resembles that of human bone and teeth, making it suitable for biomedical uses such as bone tissue engineering and implant materials. This study explores how variations in calcination temperature (750–950 °C) affect the crystal structure and mechanical properties of HAp synthesized from Pinctada maxima shells—a calcium-rich biogenic waste. The crystal structure was analyzed using X-ray Diffraction (XRD), while mechanical properties were evaluated using a Tensilon testing machine. The XRD results showed a phase shift from the dominance of tricalcium phosphate (TCP) at low temperatures towards the dominant HAp phase at high calcination temperatures with improved crystallinity from 33.94% to 45.89%. The mechanical tests showed compressive strength values of 0.1981 to 0.3148 MPa and the elastic modulus of 14.941 to 26.721 MPa. The higher calcination temperature tends to increase the cristallinity, density, and compressive strength, but reduced elasticity due to a stiffer internal structure. These results indicate that changes in crystal structure have a direct effect on increasing the compressive strength and stiffnes of the material. This study confirms the potential ofPinctada maxima shells as a sustainable calcium source for producing high-quality hydroxyapatite suitable for biomedical applications
Real-time Petty Cash Monitoring: Inovasi Web untuk Pengelolaan Anggaran Operasional yang Efisien
Get PDFThe petty cash management at PT PLN (Persero) UP3 Garut was previously conducted manually using Excel files, which were then uploaded to the SAP ERP system for financial reporting. This process lacked real-time monitoring and automated alerts when expenditures approached budget limits. This study aims to develop a web-based application to digitally monitor petty cash through weekly transaction recording, nominal validation, automated notifications, and real-time reporting. The application was developed using the waterfall model through stages of requirement analysis, UML-based system design, implementation using PHP and MySQL, and black box testing. The main result of this study is a web-based petty cash monitoring system with key features such as login, transaction input, budget validation, budget recap, and automatic notifications. Testing results showed that all functions operated properly without errors and improved weekly recording efficiency by over 70%. Data is stored locally using XAMPP to ensure financial information security. The developed application meets the unit’s internal needs and contributes to better transparency and budget control. However, the system is not yet integrated with SAP, making automated integration a future development goal
