Development of Interactive Mobile Learning Media to Enhance Motivation and Learning Outcomes in Elementary School Students’ Mathematics on Social Arithmetic
Full text linkThis study was motivated by the low motivation and learning outcomes of elementary school students in mathematics, particularly in social arithmetic, as well as the limited integration of digital technology in classroom instruction. The research aimed to develop interactive mobile learning (ML) media that is engaging, user-friendly, and aligned with the curriculum to enhance students’ motivation and achievement. The study employed a research and development (R&D) method using the ADDIE model through the stages of analysis, design, development, implementation, and evaluation. Validation by media and content experts ensured technical quality and content accuracy. A quasi-experimental design with a pretest–posttest control group was implemented. The results revealed a significant improvement in the experimental group, with the mean posttest score rising from 40.97 to 72.47, while the control group increased by only 4.99 points. Paired t-test and ANCOVA confirmed these differences, and the motivation questionnaire demonstrated high reliability (Cronbach’s Alpha >0.88). Observations and interviews supported the quantitative findings, showing increased engagement, independence, and teacher–student interaction. The interactive ML media proved effective, feasible, and ready for broader implementation as a digital learning innovation supporting 21st-century educational transformatio
The Role of Islamic Religious Education Teachers in Developing Students’ Discipline Character: A Qualitative Study
Full text linkTeachers play an important role in the formation of students' disciplined character, but there are still some teachers who cannot provide good examples in terms of discipline. This study aims to identify the approach to the formation of disciplined character and analyze the application of disciplined character carried out by Islamic Religious Education (PAI) teachers at SMA PGRI 2 Sampit, as well as analyzing the transformation of student behavior as a result of the process. The research method used is qualitative with a naturalistic approach, where data is obtained through observation, in-depth interviews, and documentation with research subjects, namely PAI teachers, and informants from the principal, BK teachers, student affairs teachers, homeroom teachers, and students. Data validation uses triangulation techniques and source triangulation, and data analysis uses the steps of reduction, data presentation, drawing conclusions and verification. The results of the study indicate that the approach to the process of forming disciplined character is carried out through: (1) habituation of worship, which instills spiritual and moral discipline; (2) teacher role models in consistent attitudes, words, and actions; and (3) spiritual strengthening through intensive religious learning and guidance at SMA PGRI 2 Sampit. Meanwhile, the application of discipline as a character builder in schools is reflected in Islamic communication, fairness and social empathy, and role models in daily interactions. The transformation of student behavior is evident in increased discipline, honesty, responsibility, independence, and self-control. This finding aligns with Al-Ghazali's view of moral education as a process of purifying the soul (tazkiyatun nafs) and cultivating good behavior, while also strengthening the relevance of modern character education theory. This study confirms that Islamic Religious Education teachers have a strategic role in building disciplined character at SMA PGRI 2 Sampi
A GIS-Based Analysis of Coastal Abrasion Risk Potential
Full text linkCoastal abrasion poses a significant threat to Indonesia, an archipelagic nation with one of the world’s longest coastlines. The phenomenon is particularly severe in Napabalano District, Muna Regency, where dense settlements, economic activities, and declining mangrove ecosystems increase exposure to erosion hazards. This study aims to assess the risk of coastal abrasion in Napabalano District using a GIS-based approach aligned with the Indonesian National Disaster Management Authority (BNPB) framework. Primary data, including GPS coordinates, satellite imagery, and field surveys, were integrated with secondary data such as demographic statistics, oceanographic parameters, and historical records of abrasion events. Spatial analysis in ArcGIS was employed to evaluate vulnerability, capacity, hazard, and disaster risk indices. Results show that all villages in Napabalano District fall into the high-risk category, with Napabalano and Napalakura recording the highest risk values due to concentrated populations, limited mangrove protection, and inadequate disaster management capacity. Social and economic vulnerabilities, including high poverty ratios and dependence on coastal livelihoods, exacerbate exposure, while institutional capacity remains critically low, marked by weak early warning systems and limited community preparedness. Mitigation strategies proposed include mangrove rehabilitation, strict coastal zoning enforcement, community-based disaster preparedness programs, and the establishment of effective early warning systems. These findings highlight the urgent need for integrated, multi-stakeholder approaches to strengthen resilience against coastal abrasion. The study provides a strategic basis for local government and community planning in managing and reducing the impacts of coastal hazards in Napabalano District
Analysis of Cs-137 Diffusion in Clay Soil and Kaolin from West Kalimantan with Groundwater Saturation
Full text linkElectricity demand in Indonesia is increasing along with economic and population growth. The plan to build a nuclear power plant (NPP) in Kalimantan needs to be accompanied by support facilities such as disposal. Research on disposal facilities in West Kalimantan is crucial because of its proximity to the planned NPP, and using local materials like kaolin and clay will be more economical. In this study, compacted clay and kaolin layers were used as part of the engineered barrier at the disposal site. The goal is to prevent the release of Cs-137 from the facility into the unsaturated zone. XRD, XRF, and ICP-OES were used to characterize the clay and kaolin studied. Analysis revealed many absorbent minerals suitable for the engineered barrier at the disposal site.To evaluate the diffusion coefficient (Da) of Cs-137 in compacted clay and kaolin samples, a vertical diffusion model was employed. The diffusion coefficient was measured in a diffusion column unit with varying times and densities. Fick's law equation was used to calculate the Da value for the samples. The results showed that the diffusion coefficient for kaolin ranged from 2.75 x 10-12 to 3.96 x 10-12 m²/s, and for clay from 1.62 x 10-12 to 2.92 x 10-12 m²/s. In clay and kaolin samples, density affected the diffusion rate; higher density resulted in a lower Da value. However, time did not impact the Da value. The diffusion coefficient in kaolin was twice as fast as in clay samples.In the safety assessment experiment with RESRAD Offsite, a 0.2 m kaolin layer was sufficient
Initial Emergency Management of Trauma: A Literature Review
Full text linkTrauma continues to be one of the leading causes of mortality and disability worldwide, including in Indonesia, with the most critical period occurring within the golden hour. Elevated mortality rates are often linked to delayed medical response, the absence of standardized treatment protocols, and limited healthcare resources. Objective: This review aims to assess the effectiveness of internationally recognized, protocol-driven interventions that have been adapted to the Indonesian context in enhancing trauma care outcomes. A systematic-narrative literature review was conducted in accordance with the PRISMA 2020 guidelines. Sources included SINTA, Scopus, ClinicalKey, as well as conference proceedings and dissertations published between 2023 and 2024. Each study was evaluated for methodological rigor, strength of evidence, and applicability to emergency care settings in Indonesia. Thematic analysis was applied to synthesize the findings. Adaptations of ATLS protocols, interdisciplinary simulation-based training, and the implementation of digital technologies for triage and prehospital communication demonstrated the potential to reduce trauma-related mortality by up to 30%. Furthermore, the early administration of tranexamic acid (TXA), application of tourniquets, and whole blood transfusion proved highly effective in managing severe trauma cases. The integration of international trauma care protocols with locally contextualized innovations and digital health technologies holds significant promise for improving the quality and effectiveness of trauma management in Indonesia
The Dual Role of Women and Digital Literacy in Improving the Performance of the Home and Industrial Social Center of the Fisherwomen's Group: JEL Classification: J16, O33, D83, J22, L26
No full textThis paper explores how fisherwomen in Makassar mediate the compounded tensions of family obligation and economic labor of co-operation as they adjust to digital technologies in the Home and Industrial Social Center. With a qualitative descriptive design, which is supported by phenomenology and has a linkage-bridging viewpoint, the study looks at how digital literacy is transforming quotidian practices, moderating collaborative practice, and intertwining with culturally normative values that command shared practice. Fifteen participants were interviewed using in-depth interviews and participant observation and reviewed documents, which allowed gathering data related to the pragmatic experience, as well as the emotional and embodied aspects of digital engagement. The results suggest that the digital literacy is a transformative force that broadens the market, enhances the efficiency of the operations, and strengthens the feeling of agency in the fisherwomen. At the same time, it is associated with new stressors, such as physiological exhaustion, time disruption, and increased domestic tension levels in regard to prolonged online activity. Instead of reducing the dual burden, the digital tools re-structure it into a hybrid taxonomy of domestic, manual and digital work which the women have to negotiate all the time. The analysis of linkage-bridging shows that internal resources (siri Naa pacce and peer-based learning) are compatible with external digital resources to enable adaptive capabilities within the cooperative. This overlap brings about the Dual Digital Bridge framework which illustrates how local cultural values can be made in line with technological innovation in coastal locations
Strengthening MSME Digital Transformation through Android-Based Geolocation Mapping: Implementation of Location-Based Services and the Haversine Formula
Full text linkInformation and Communication Technology (ICT) plays a strategic role in reducing socio-economic disparities and accelerating inclusive development, especially in rural areas. In Indonesia, Micro, Small, and Medium Enterprises (MSMEs) are the dominant sector, absorbing over 96% of the workforce and contributing around 60% to the national Gross Domestic Product (GDP). However, many MSME actors particularly in remote regions such as North Sulawesi still face challenges in accessing digital markets due to limited technology adoption and lack of business location exposure. This study aims to develop an Android-based application that integrates geolocation services through the implementation of Location-Based Services (LBS) and the Haversine formula. LBS is used to detect users' real-time locations via GPS, while the Haversine formula calculates the precise distance between users and MSME locations. The application is designed to send automatic notifications when a user is within a 1000-meter radius of a registered MSME location. This research adopts a software engineering approach through the design of context diagrams, system flowcharts, and the implementation of the Haversine algorithm using the Dart programming language. Testing results show that the distance difference between the application and Google Maps ranges only from 1.5 to 2.9 meters, and the distance calculated by the application matches 100% with online Haversine calculators. These findings indicate that the system has high accuracy and is feasible to be applied as a solution to improve MSME visibility, enhance community digital literacy, and strengthen the local economy through e-commerce
Comparative Analysis of the Support Capacity and Settlement of Bored Pile Foundations Using Manual Methods and Allpile Software: Case Study
Full text linkFoundations are structural elements that function to bear the load of a building and transfer it to the ground to a certain depth. Foundations must be designed so that the transferred load does not exceed the bearing capacity of the soil, as this can cause excessive settlement and lead to structural collapse. The purpose of this study is to determine the comparison of bearing capacity and settlement of bored pile foundations in the Poltekkes Kemenkes Mataram building using two approaches: the manual method and the Allpile software. The analysis was conducted based on secondary data obtained from the Detailed Engineering Design (DED), results of the Standard Penetration Test (SPT), and laboratory soil test results. The results of the manual Meyerhof method yielded an ultimate bearing capacity of 13,127.79 kN and a single pile settlement of 0.0455 m. The manual Reese and Wright method yielded an ultimate bearing capacity of 2,697.3453 kN and a single pile settlement of 0.0241 m. Meanwhile, the Allpile software calculation yielded an ultimate bearing capacity of 14,391.891 kN and a single pile settlement of 0.0027 m. All settlement values, both for single piles and groups, remain below the maximum permitted limit
Analysis of the Effectiveness of the Family Hope Program in Poverty Alleviation: An Islamic Economic Perspective: Case Study
Full text linkThis study examines the effectiveness of the Family Hope Program (PKH) in alleviating poverty from the perspective of Islamic economics, focusing on the case study of Sorkam Barat Sub-district, Tapanuli Tengah Regency. The research delves into the context where despite the implementation of PKH, poverty persists in the region, possibly due to misalignment with Islamic economic principles or inefficiencies in the program's execution. The study poses questions regarding the PKH's impact on poverty alleviation and its compatibility with Islamic economic principles. Employing a qualitative approach, data collection involves interviews, document analysis, and observations. The findings reveal various challenges hindering the PKH's effectiveness, such as improper targeting, lack of awareness among beneficiaries, and delays in aid disbursement. In addressing these issues, the study recommends enhancing the program's alignment with Islamic economic principles, improving targeting mechanisms, raising awareness among beneficiaries, and streamlining aid distribution processes. Ultimately, the research contributes to the discourse on poverty alleviation strategies and highlights the importance of considering Islamic economic perspectives in social welfare programs
Nebulized Dexmedetomidine to Reduce Delirium after General Anesthesia Sevoflurane Inhalation in Preschool Children Undergoing Elective Surgery
Full text linkSurgery in children remains a major challenge, particularly due to complications such as post-anesthetic delirium, with an incidence rate of up to 80%, especially in preschool-aged children when sevoflurane is the primary agent. Nebulized dexmedetomidine has been shown to reduce the incidence of post-anesthetic delirium with minimal risk of side effects. This study aims to evaluate the effectiveness of nebulized dexmedetomidine in reducing the incidence of post-anesthetic delirium in preschool-aged children undergoing elective surgery, as part of enhancing recovery after pediatric surgery (ERAPS). This research was a double-blind, randomized controlled trial, involving 72 pediatric patients aged 2–6 years undergoing elective surgery under general anesthesia with sevoflurane. Subjects were randomly divided into two groups; Treatment group receiving nebulized dexmedetomidine 2 mcg/kg (n=36) and Control group receiving nebulized normal saline (n=36). The primary outcome was the incidence of delirium during recovery at 15, 30, 60, and 120 minutes, assessed using the Pediatric Anesthesia Emergence Delirium (PAED) Scale. Statistical analysis revealed a significantly lower incidence of post-anesthetic delirium in the nebulized dexmedetomidine group (19.4%) compared to the control group (52.8%) at 15, 30, and 60 minutes (p<0.05), with a reduction in proportion by 33.4% (p=0.003). Relative risk analysis (RR = 0.427, 95% CI: 0.218–0.835; PF = 0.631) demonstrated that dexmedetomidine provides protective effects and significantly reduces the incidence of post-anesthetic delirium in preschool-aged children undergoing elective surgery with sevoflurane inhalational anesthesia. No side effects requiring intervention were observed during this study
