Abstract

This study investigates the phenomenon of language transfer among multilingual students at an Islamic boarding school, focusing on the morphosyntactic structures in recount texts written by students. Using descriptive quantitative methods, the research was conducted at a boarding school in South Kalimantan. Data were collected through free-writing exercises with ten selected students. The findings showed no significant statistical difference in language transfer between English and Arabic. However, interviews indicated that students often use Indonesian when forming sentences in English and Arabic, supporting the TPM theory. Future research should include a larger sample size, particularly from boarding schools, as each institution’s unique approach to multilingual education can influence language transfer in different ways.

Abstract

In the 21st century, fostering critical thinking and problem-solving skills is essential for students. This study analyzes the manifestation of Higher Order Thinking Skills (HOTS) and Lower Order Thinking Skills (LOTS) in the English textbook ‘English for Nusantara’ for Grade VII. HOTS involves higher-level cognitive processes such as analysis, evaluation, and creation, while LOTS focuses on recall and comprehension. Involving a qualitative research design with a content analysis approach, this study applied Revised Bloom’s Taxonomy, which categorize exercises into LOTS (remember, understand, and apply) and HOTS (analyze, evaluate, and create). A total of 116 exercises in the form of instructions and 67 exercises in the form of questions from listening, speaking, reading, and writing tasks were analyzed. To maintain consistency, inter-rater reliability was ensured, where the analysis was cross-verified through discussions with a validator. The findings show that LOTS dominates the exercises, with 81% of the exercises are in the form of instructions and 89% in the form of questions. This indicates a heavy emphasis on LOTS and suggests an opportunity for more HOTS integration. Based on these findings, the study recommends that teachers incorporate more HOTS-focused activities, and textbook authors should design future editions with a stronger emphasis on HOTS exercises to foster critical thinking skills. Such adjustments would better equip students to meet the demands of the 21st century.

Abstract

Deoxyribonucleic acid (DNA) is a research object for various molecular fields of study, and DNA extraction is a basic procedure in molecular biology laboratories. DNA extraction methods are evolving, from several steps using organic solvents to recent technology using magnetic nanoparticles as adsorbents for the purification step. The use of magnetic nanoparticles for DNA extraction is magnetizing because it is simple without heavy machinery, such as centrifugation and organic solvents. The application of this method is extensive and diverse. This systematic review summarizes current development trends for some aspects of this DNA extraction system from the magnetic nanoparticle synthesis method, extraction protocol, and different types of samples used. The main purpose of this review is to provide an overall perspective of the use of magnetic nanoparticles in DNA extraction for researchers to start their exploration of this safe, simple, and rapid technique. In general, the most well-known magnetic nanoparticle preparation uses the coprecipitation method. The preferred particle is a plain and silica-coated magnetic nanoparticle using tetraethyl orthosilicate. The most common buffer systems for binding, washing, and elution are Polyethylene Glycol (PEG) and NaCl, 70% ethanol, and Tris–EDTA, respectively. The extraction system with magnetite can be used for various types of samples, ranging from human specimens to animal, plant, and bacterial specimens. The extraction yields using the magnetic-nanoparticle-based method were between 0.03 µg and 116.63 µg with a DNA purity ratio between 1.09 and 1.99.

Abstract

With its rich diversity of ethnicities, cultures, races, and religions, Indonesia is one of the countries with the highest number of regional languages in the world. This linguistic diversity often leads to communication challenges, particularly when conveying information or engaging in textual conversations. This study aims to identify and classify the Toraja, Batak, and Ambon languages using machine learning-based computational methods. The techniques employed include Decision Tree and Gradient Boost algorithms to evaluate the accuracy of each model. The results demonstrate that both Decision Tree and Gradient Boost are effective in language identification, achieving accuracy rates above 77%. However, based on the confusion matrix analysis, the Gradient Boost method proved to be more effective, with an accuracy rate of 81.06%, compared to 78.39% achieved by the Decision Tree. These findings suggest that Gradient Boost offers better performance for classifying these regional languages.

Abstract

Lentera Grill Restaurant faces long customer queues due to manual ordering processes, particularly during peak hours. Our research aimed to reduce wait times and improve service accuracy through technology. We designed and built a web-based reservation system using Python, React, and MongoDB that applies the FCFS (First Come First Served) method to process orders in sequence of arrival. Testing involved two phases: functional validation through Blackbox Testing of all user pathways, and performance assessment using JMeter with 20, 50, and 100 simultaneous users. Results showed the system maintained stable throughput with zero error rates across all load scenarios, though we observed latency spikes during heavy traffic that require attention. The FCFS implementation reduced average wait times by 37% compared to the previous manual system and increased customer satisfaction ratings in post-implementation surveys. Restaurants with similar queue management challenges would benefit from adopting such technology-based solutions that balance customer experience with operational efficiency

Abstract

This study examines the psychometric qualities of a tryout test administered to 283 in-service English teachers in Indonesia, using Classical Test Theory (CTT) procedures. The analysis focused on five indices: item validity, discrimination, difficulty, distractor functioning, and item utilization. Results revealed several weaknesses in the test design. Only 46% of items demonstrated acceptable validity, while 54% failed to align meaningfully with the overall construct of teacher competence. More than half of the items showed poor discrimination, limiting the test’s ability to differentiate high- and low-performing teachers. Difficulty levels were skewed, with 72% of items categorized as easy, thereby restricting the measurement of higher-order thinking skills. Distractor analysis indicated that three-quarters of options were non-functioning, reducing diagnostic value. Consequently, only 9% of items could be retained without revision. Despite these shortcomings, the findings provide useful insights into teacher competencies. While basic linguistic and pedagogical knowledge was well represented, higher-order professional skills such as inference, synthesis, and applied pedagogy were under-assessed. These results highlight the importance of strengthening assessment literacy and integrating item analysis into teacher professional development.

Abstract

This study aims to investigates the effectiveness of using flashcards to teach English vocabulary to young learners. The research was conducted at SDN Gempol 2 with 36 third-grade students. A one-group pre-experimental design was employed, using pre-test and post-test to collect the data. The results revealed a significant improvement in students' vocabulary mastery, with the average score increasing from 65.83 (pre-test) to 76.80 (post-test). Statistical analysis showed that the t-value (11.056) exceeded the critical value (2.035), and the significance level (p = .000) was below the threshold of 0.05, indicating a meaningful difference. These findings suggest that flashcards are an effective tool for enhancing vocabulary acquisition among young learners, as they help maintain students’ engagement through visual and interactive learning.

Abstract

Growth performance, survival rate, productivity, and carcass analysis were examined in the whole grow-out production system for Pacific white shrimp Litopenaeus vannamei fed four commercial diets over 15 weeks. Shrimp were held in twelve hapas nets with a size of 2 x 2 x 1 m and installed within the commercial ponds. The shrimp were stocked with the density of 100 shrimp m-2 per net in a completely randomized design (CRD). All feed used in this study was characterized with high protein levels within the range of 40 – 42% labeled as HP A and B; and medium protein levels (30 – 35%), labeled as MP A and B. Based on the proximate and nutritional profile analysis of the diet, the nutritional profile of HP B, MP A and MP B written on the feed bags showed an inconsistent results compared to the results of the test.  Shrimp fed the highest protein level had higher final body weight; feed conversion ratio, thermal growth coefficient, survival rate and average daily growth compared to MP B. Shrimp fed higher protein level also exhibited the lowest feed conversion ratio compared to the group of shrimp fed with medium protein. The results obtained in this study indicated that with small difference in growth rates, especially between HP groups compared with MP A, there is still a chance to re-formulate the diet to produce a cost-effective diet that still fulfill the specific nutrient requirement of the shrimp. Feed did not influence the nutritional deposition of the whole body of shrimp, but it seemed due to the inappropriate drying techniques Keywords: Protein level, growth, carcass, Litopenaeus vannamei, specific nutrient
