The Effect of Complimentary Split Ring Resonator Placement on Antenna Patch and Ground Plane to Microstrip Antenna Reduction Dimension and Bandwidth

This reasearch is aimed to observe the comparison of CSRRs performance on Antenna Patch and Ground Plane so that the Antenna can be implemented in ADS-B frequency.  The CSRR outer dimension is 13 mm x 10 mm and  the inner dimension is 9 mm x 6 mm, obtained  of Return loss and VSWR simulation are respectively -13.7860 dan 1.5141. The iteration is done after the CSRR is added to its Patch and ground plane so that return losses  are -10,329 dB and -13,554 dB and the VSWRs  obtained were 1.8755 and 1.5317. In addition, the redution of Patch and Ground plane dimensions also is occurred when CSRR is on Patch by 18.5% and 30.2%, reduction Patch and Ground plane dimension occurred when CSRR is on Ground plane by 24.1% and 23.16%.  Etched on Patch and Ground plane, CSRRs effect Bandwidth, Bandwicth decreases at 0.015 GHz at CSRRs on patch and increases at 0.040 GHz whereas Bandwidth is 0025 GHz before CSRRs is etched.  This reasearch is aimed to observe the comparison of CSRRs performance on Antenna Patch and Ground Plane so that the Antenna can be implemented in ADS-B frequency.  The CSRR outer dimension is 13 mm x 10 mm and  the inner dimension is 9 mm x 6 mm, obtained  of Return loss and VSWR simulation are respectively -13.7860 dan 1.5141.

The Use of Gamification-Based Duolingo Application in Increasing Student Motivation is Reviewed From the Theory of Self-Determination

This study aims to evaluate the extent to which the gamification-based Duolingo application can increase students' motivation in learning Arabic, especially in vocabulary mastery or mufrodat, with the Self-Determination Theory (SDT) theoretical approach. SDT focuses on the importance of intrinsic motivation, which is driven by three main aspects: autonomy or independence, competence or ability, and interconnectedness or relationships that are established in the context of learning. This study uses a quantitative approach with a Descriptive Survey design to provide a more real picture of the influence of the use of this application on student motivation. Data collection was carried out with an SDT questionnaire instrument that measured the level of student motivation through the three main components. The results of the data analysis showed a significant increase in motivation among students who participated in the experiment. These findings indicate that the gamification-based Duolingo application plays a role in increasing students' intrinsic motivation in learning mufrodat, especially by strengthening a sense of independence, improving perceived abilities, and creating a sense of connectedness or relevance in the learning process. Gamification-based Duolingo has great potential as an effective tool in language learning, especially in helping to increase students' motivation to master new vocabulary. It is evidenced by the questionnaire data which got a score of 88%. Keywords: Duolingo, gamification, Self-Determination Theory, mufroda

Study on Flood Control of the Sumber Pinang River in Sidogiri, Pasuruan Regency through River Normalization, Levees, and Parapet Walls

The Sumber Pinang River in Pasuruan Regency frequently experiences flooding due to its insufficient capacity. This study aims to analyze flood control measures using hydrological and hydraulic approaches with the HEC-RAS 6.4.1 software. The data used include maximum rainfall, river cross-section profiles, and land use. The planned flood discharge was calculated using the Nakayasu Synthetic Unit Hydrograph (SUH) method, resulting in a peak discharge of 442.823 m³/s. The analysis results indicate that 81% of the river cross-sections are prone to overflow. Proposed control measures include river normalization and the construction of levees and parapet walls. River normalization is planned for the entire river body, while levees and parapet walls are proposed at critical points to enhance the river's capacity. This study provides recommendations for more effective flood control planning in the future.The Sumber Pinang River in Pasuruan Regency frequently experiences flooding due to its insufficient capacity.

Classification of Anaemia Status Using The K-Nearest Neighbor Algorithm

Early detection and accurate diagnosis of anemia are crucial for public health management, with conventional methods like complete blood count often being costly and unavailable in remote areas. The use of machine learning techniques, specifically the k-nearest neighbor (KNN) algorithm, shows promise in classifying medical conditions including anemia with competitive accuracy compared to traditional methods. The implementation of KNN not only offers accuracy but also time and cost efficiency, providing reliable results quickly for medical professionals in the field. The algorithm's application involves determining the appropriate k-value for optimal accuracy, calculating distances using Euclidean distance, and voting for class prediction based on nearest neighbors. The analysis showcases the model's efficiency in predicting anemia status with an accuracy of 94.72% and promising precision and recall rates.arly detection and accurate diagnosis of anemia are crucial for public health management, with conventional methods like complete blood count often being costly and unavailable in remote areas.

Mengungkap Peran Strategis Sukuk dan Saham Syariah dalam Mendorong Pertumbuhan Keuangan Syariah di Era Modern

This study examines the impact of sukuk and Islamic stocks on the development of Islamic finance in Indonesia during the period 2015–2023. The main focus of this research is to understand the strategic role of these two Islamic capital market instruments in driving the growth of the Islamic finance sector, which includes banking, insurance, and Islamic microfinance institutions. The methodology used is quantitative analysis with a Structural Equation Modelling - Partial Least Squares (SEM-PLS) approach. The results show that Islamic sukuk has a positive and significant impact on the performance of Islamic finance, with a path coefficient of 0.846 and a p-value < 0.05, while Islamic stocks show a weak and insignificant relationship with the performance of Islamic finance, with a path coefficient of 0.195 and a p-value > 0.05. These findings indicate that Islamic sukuk plays a more dominant role in supporting the growth of the Islamic finance sector in Indonesia, while Islamic stocks require further development, including increasing financial literacy and public interest in these instruments. This study contributes theoretically by expanding the literature on Islamic finance and practically by providing recommendations for regulators to strengthen the role of Islamic sukuk in supporting sustainable Islamic finance in Indonesia.Penelitian ini mengkaji pengaruh sukuk dan saham syariah terhadap perkembangan keuangan syariah di Indonesia pada periode 2015–2023. Fokus utama penelitian ini adalah untuk memahami peran strategis kedua instrumen pasar modal syariah tersebut dalam mendorong pertumbuhan sektor keuangan syariah, yang meliputi perbankan, asuransi, dan lembaga keuangan mikro syariah. Metodologi yang digunakan adalah analisis kuantitatif dengan pendekatan Structural Equation Modeling - Partial Least Squares (SEM-PLS). Hasil penelitian menunjukkan bahwa sukuk syariah memiliki pengaruh positif dan signifikan terhadap kinerja keuangan syariah, dengan koefisien jalur sebesar 0.846 dan nilai p < 0.05, sementara saham syariah menunjukkan hubungan yang lemah dan tidak signifikan dengan kinerja keuangan syariah, dengan koefisien jalur sebesar 0.195 dan p > 0.05. Temuan ini mengindikasikan bahwa sukuk syariah berperan lebih dominan dalam mendukung pertumbuhan sektor keuangan syariah di Indonesia, sementara saham syariah perlu pengembangan lebih lanjut, termasuk peningkatan literasi keuangan dan minat masyarakat terhadap instrumen ini. Penelitian ini memberikan kontribusi teoritis dalam mengembangkan literatur keuangan syariah serta praktis dalam memberikan rekomendasi bagi regulator untuk memperkuat peran sukuk syariah dalam mendukung keuangan syariah yang berkelanjutan di Indonesia
