Abstract

This study aims to explore how eighth-grade students’ learning styles, based on Multiple Intelligences, manifest in geometry learning, and to address the research question: How can learning diversity in solving geometry tasks be revealed through the lens of the eight Multiple Intelligences? Using a qualitative approach with a descriptive phenomenological method, nine participants (N = 9) were purposively selected from a pool of 357 students through questionnaires, interviews, observations, and artifact analysis. Each participant represented one of six dominant intelligences according to the theories of Gardner and Armstrong (2018). The findings show that instruction tailored to students’ dominant intelligences enabled them to complete tasks in distinctive ways—for example, building physical models for kinesthetic learners or composing mathematical narratives for verbal learners. This adaptation facilitated active engagement, deeper conceptual understanding, and authentic learning expression. The study highlights the importance of intelligence-based differentiated instruction in geometry teaching to optimize diverse learning potentials.

Abstract

In the global agricultural sector, Indonesia is the largest producer of palm oil within the agricultural sector.  Palm fruit is then processed into palm oil. This research optimizes the distribution cost of crude palm kernel oil (CPKO) at Agrojaya Perdana by addressing transportation imbalances.  The study uses a Modified ASM method, which adds a dummy column to handle excess production capacity, followed by row and column reduction to identify optimal allocations. The initial solution from the Modified ASM method is then further optimized using the Stepping Stone method.  The results show a significant cost reduction of Rp 15,132,000.00 (approximately 2.251%) compared to the initial distribution cost of Rp 672,336,000.00, demonstrating the effectiveness of the combined Modified ASM and Stepping Stone methods in resolving transportation imbalances and optimizing distribution costs for PT. Agrojaya Perdana.

Abstract

The selection of superior food crop commodities at the regional level is very important to sup-port agricultural development policies, but it is often carried out without comprehensive strategic analysis, risking less accurate decisions. The objective of this research is to establish the superior commodities of the food crop subsector in Langkat Regency based on regional contributions and a number of strategic criteria. The methods used include Location Quotient (LQ) to measure the region's comparative advantage based on production contribution, as well as Fuzzy ARAS to evaluate seven commodities based on ten strategic criteria with expert assessment using triangular fuzzy numbers. The results show that rice is the base commodity in 13 districts and has the highest contribution distribution. However, soybeans have become the superior commodity with the highest relative utility value (1.029), followed by cassava (1.015) and rice (0.983). The LQ and Fuzzy ARAS methods have proven effective in supporting the de-termination of superior commodities based on local potential.

Abstract

The background of this research is that the learning conditions of students appear less conducive, many students appear unenthusiastic in participating in lessons. They often make noise, daydream, sleep in class and even fight with each other. The teacher who teaches has difficulty attracting their attention, because most students are more interested in playing than studying. In addition, the teacher rarely uses media and learning models when teaching, he only often uses the lecture method, so that students are easily bored and uninterested in participating in learning. This can be evidenced by the lack of student interest in participating in learning and low learning outcomes, and resulting in learning objectives not being achieved. With these various factors, students' interest in learning at the school is low, which has an impact on their less than satisfactory academic achievement. This study used a qualitative descriptive research method. The results of this study, namely the application of visual learning media (images) combined with the Problem Based Learning (PBL) model effectively increased student learning interest in science learning. This improvement was seen in five main aspects: students showed a feeling of enjoyment while learning, were more active and involved in learning activities, had a high interest in the material, paid more attention when the teacher delivered the material, and had a strong desire to learn.

Abstract

Teachers do not simply conduct online or remote learning by delivering materials to learners, but rather through optimal preparation to ensure effective implementation. The shift to long-distance learning during the Covid-19 pandemic required teachers to master their subject matter, align personal interests and talents with educational goals, and demonstrate a positive professional attitude. This study aimed to determine the readiness of primary school teachers in implementing online learning during the Covid-19 pandemic. Using a quantitative survey design, the research was conducted in primary schools across the Jakarta metropolitan area (Jakarta, Bogor, Depok, Tangerang, Bekasi). Participants (n=280) were selected using a combination of random and convenience sampling techniques. Data were collected using the Teacher Readiness for Online Learning Measurement (TROLM) instrument developed by Ming Hu in 2015 and analyzed using percentage calculations. The results showed that teachers demonstrated emotive attitudinal readiness of 54.4%, cognitive readiness of 55.9%, and behavioral readiness of 51.5%, indicating that overall, they are well-prepared to implement online learning. Based on these findings, it is recommended that continuous professional development, adequate digital infrastructure, and sustainable policy guidelines be provided to further enhance teachers’ digital pedagogical competencies and ensure the long-term effectiveness of online learning beyond the pandemic context
