Elementary school teacher performance plays a pivotal role in enhancing the learning process. This study investigates key elements that affect teacher performance, including personal (internal) aspects, environmental (external) influences, leadership from school principals, and levels of teacher professionalism. Using a literature review approach, the study compiles data from relevant sources. The results reveal that teacher performance is shaped by motivation, satisfaction at work, support from school management, and both pedagogical and professional competence. This suggests that improving teacher effectiveness requires a holistic strategy. The study implies the importance of formulating education policies that continuously support teacher development and strengthen leadership to foster a productive educational climate.

This study aims to analyze the competitive advantage strategy of Islamic Banks using the Porter's Five Forces approach, which is used to understand the competitive position of Islamic Banks in facing the dynamics of the financial industry that continues to grow. This study includes qualitative research methods with the approach of Field research and Library research, which are supported by interviews or observations as the main data collection techniques. The results of the study indicate that the Threat of New Entrants BSI Karang Kobar is aware of the threat of new entrants and faces internal challenges, especially in the marketing aspect which is still low. Customer strength is shown through the influence of satisfaction with products and employee behavior on loyalty, especially on flagship products such as KPR, gold installments, and micro financing. Supplier strength shows that there is a great opportunity for suppliers to establish partnerships with Islamic financial institutions. The threat of substitute products has not been found directly, but digital transformation to the Byond By BSI platform is a concern. In industrial competition, BSI Karang Kobar admits that it still faces challenges, such as limited economies of scale compared to conventional banks. Thus, the application of sharia principles in the formulation of business strategies allows Islamic banks to build customer loyalty and create sustainable competitive advantages. Porter's Five Forces approach has proven to be relevant and effective in helping Islamic banks formulate adaptive and valuable strategies in facing competition in the modern financial industry.

This study aims to examine the factors influencing students' financial management behavior, focusing on the roles of financial attitude, financial knowledge, and internal locus of control, while also considering financial technology as a moderating variable. Data were collected from 196 students at Dian Nuswantoro University and Semarang State University using a Likert-scale questionnaire. The findings indicate that financial attitude and financial knowledge significantly influence financial management behavior. Furthermore, financial knowledge significantly affects internal locus of control, which in turn influences financial management behavior. However, financial technology does not moderate the relationship between internal locus of control and financial management behavior. These results highlight the importance of comprehensive financial literacy and the prudent use of financial technology to support effective financial management among university students.

Penelitian ini mengeksplorasi penerapan dari metode Parameter-Efficient Finetuning (PEFT) Low-Rank Adaptation+ (LoRA+) pada transfer learning model Llama 3.2 1B, sebuah model bahasa besar. Seiring bertambahnya ukuran model bahasa, finetuning yang dilakukan secara konvensional dalam transfer learning semakin tidak fisibel untuk dilakukan tanpa menggunakan komputasi skala besar. Untuk menangani hal tersebut, dapat dilakukan finetuning pada beberapa komponen saja, menggunakan komputasi yang relatif minimal berbanding dengan finetuning konvensional, metode-metode yang menerapkan prinsip ini disebut juga sebagai PEFT. Penelitian menguji efektifitas metode PEFT, yakni LoRA+, pada transfer learning model bahasa besar terhadap domain baru, yakni bahasa Indonesia, menggunakan metrik BLEU, ROUGE, serta Weighted F1. Hasil penelitian menunjukkan bahwa penerapan LoRA+ menghasilkan performa kompetitif dan unggul terhadap baseline dalam kemampuan berbahasa Indonesia, dengan peningkatan 112% pada skor BLEU dan 21.7% pada skor ROUGE-L, dengan standar deviasi yang relatif rendah sebesar 3.72 dan 0.00075. Meskipun terjadi penurunan pada skor Weighted F1 sebesar 13% yang disebabkan oleh domain shift, model menunjukkan kemampuan transfer lintas-bahasa yang baik.

This study aims to analyze the optimization of seaweed seedling inventory management using the Economic Order Quantity (EOQ) method to enhance cost efficiency for farmers in Tarakan City. The research employs a quantitative descriptive approach, integrating EOQ with forecasting techniques (Moving Average and Exponential Smoothing) to predict raw material needs accurately. Data were processed using Microsoft Excel and POM-QM for Windows to ensure precision. The results indicate that EOQ yields an optimal order quantity of 878 ropes per order, with a frequency of 6 orders per year, a reorder point of 16 ropes, and a total inventory cost (TIC) of IDR 842,681. Compared to traditional methods (TIC IDR 2,132,083), EOQ reduces costs by 60.5%. Forecasting analysis reveals that Exponential Smoothing (MAPE 19.67%) outperforms Moving Average (MAPE 22.5%) in accuracy. These findings highlight EOQ’s effectiveness in minimizing waste, preventing stockouts, and improving productivity. The study provides practical insights for coastal small-scale farmers and policymakers in the marine sector.

Balai Pungut village has a lot of tourism potentials that could be develop to attract visitors more.

Bioethanol can basically be made with basic ingredients in the form of vegetables which contain high starch and carbohydrates such as taro tubers (Colocasia esculenta [L] Schott). The choice of taro in making ethanol is because taro is classified as a tuber like cassava which has 66.8% starch content and 7.2% water content. The process of making glucose is done through acid hydrolysis (HCl) with variations in acid concentration (12, 14, 16, 18, and 20%) and hydrolysis time (1.5; 2; and 2.5 hours). From the analysis, it can be seen that the result of hydrolysis is liquid sugar (glucose) with the highest level of 27.8%brix.

The results of the study show that virtual communication has become an important part of the learning process during the pandemic. Various platforms such as Zoom Meetings, Google Classroom, and Google Meet are widely used by educators and students to support interaction and the effectiveness of the teaching and learning process. This study also highlights changes in communication patterns, challenges faced by users, and the importance of technological readiness and digital literacy in supporting effective virtual learning during a crisis such as a pandemic.

This research analyzes user sentiment reviews of the KAI Access application from Google Play Store to improve customer service at PT Kereta Api Indonesia. The study uses a Natural Language Processing (NLP) approach with the Latent Dirichlet Allocation (LDA) algorithm to extract main topics from 10,000 reviews collected from April 2024 to April 2025. Analysis results show 40.7% positive sentiment reviews and 49.3% negative. After data preprocessing through case folding, normalization, tokenization, stopword removal, and stemming, seven optimum topics were found from negative sentiment with a coherence score of 0.508343 and two optimum topics from positive sentiment with a coherence score of 0.511673. Analysis based on five service quality dimensions (tangibles, reliability, responsiveness, assurance, and empathy) reveals that the reliability dimension becomes the main issue, including system instability, transaction failures, login difficulties, and data inaccuracy. The responsiveness dimension is the second priority, with users expecting fast and responsive service to complaints. The results of this study provide recommendations for PT KAI to prioritize improvements in system reliability and responsiveness aspects to enhance the overall user experience, which will ultimately impact customer satisfaction and loyalty.
