Penerapan sistem intercropping dalam pengelolaan hama tanaman jagung (Zea mays L.)
No full textMaize production in tropical regions is frequently threatened by insect pests, leading to significant yield losses. Environmentally friendly strategies such as intercropping offer potential solutions for pest suppression while enhancing crop productivity. This study aimed to evaluate the effectiveness of different intercropping combinations in improving maize production by reducing pest pressure. The research was conducted using a Randomized Block Design (RBD) with five treatments: monoculture maize, and maize intercropped with groundnut, citronella, Zinnia refugia, and chili, each replicated three times. Observed variables included yield components such as the number of kernel rows per cob, kernels per row, weight of 100 kernels, and yield per unit area. Results showed that maize intercropped with Zinnia refugia produced the highest performance in most yield components, significantly increasing row number per cob, kernels per row, and total yield compared to monoculture. Meanwhile, citronella intercropping resulted in the highest 100-kernel weight. In contrast, intercropping with chili resulted in the lowest yield, possibly due to resource competition or allelopathic effects. The findings suggest that specific intercropping patterns, particularly those involving refugia or repellent plants, can enhance maize productivity and serve as effective pest management strategies. Further research is recommended to validate these findings under diverse agroecological conditions

The data obtained were analyzed using Analysis of Variance, and if the test results showed differences, further testing was conducted using the Duncan Multiple Range Test (DMRT). The main treatments were different levels of nitrogen fertilizer application, namely concentrations P0 (0 ml/l), P1 (0.8 ml/l), P2 (1.6 ml/l), P3 (2.4 ml/l). The results showed that different levels of nitrogen fertilizer application did not have a significant effect (P>0.05) on plant height, had a significant effect (P<0.05) on leaf width, leaf length, and stem length, and had a highly significant effect (P<0.01) on stem diameter and number of leaves in hydroponic corn fodder. The research results showed that the growth profile, viewed from the morphology of the stem and leaves in hydroponic corn fodder, showed the best values with increasing N doses, with the best research results shown at the use of N fertilizer dose of 1.6 ml/l (P2). Increasing the level of nitrogen fertilizer can enhance leaf width, leaf length, number of leaves, stem length, and stem diamete
Optimizing groundnut seedling growth on post-tin mining soil by adding organic growing media
No full textSoils from post-tin mining soil typically exhibit suboptimal conditions for plant growth due to low organic matter content, sandy texture, and the presence of heavy metal wastes. Groundnuts (Arachis hypogaea L.) are a highly nutritious food crop of significant economic importance, rich in protein and fat. Enhancing the quality and fertility of old tin mine soils can be accomplished by adding organic growing media to facilitate optimal groundnut cultivation. This study aims to enhance groundnut growth by the addition of organic planting media and determining of the optimal dosage. This study used a Completely Randomized Design (CRD) using organic planting media with four treatment levels: P0 = control (no organic planting media), P1 = 85% post-tin mining soil + 15% organic growing media, P2 = 75% post-tin mining soil + 25% organic growing media, P3 = 60% post-tin mining soil + 40% organic growing media. Each treatment was replicated five times, giving a total of 20 experimental units. Data were evaluated utilizing Analysis of Variance (ANOVA) succeeded by Duncan's Test at the 5% significance level. The addition of organic growing media into post-tin mining soil influenced root biomass in groundnut plants, showing a tendency to enhance leaf count and canopy biomass, however this effect was not statistically significant. This study found no significant effect on plant height

THE EFFECT OF PROBLEM-BASED LEARNING MODEL WITH TARL APPROACH ON NATURAL AND SOCIAL SCIENCES LEARNING OUTCOMES AND CRITICAL THINKING SKILLS IN ELEMENTARY SCHOOL
No full textThis research investigates the effect of integrating the Problem-Based Learning (PBL) model with the Teaching at the Right Level (TaRL) approach on fifth-grade students’ critical thinking skills and learning outcomes in natural and social sciences. The background highlights low student achievement and inadequate critical thinking, often caused by conventional, teacher-centered methods that fail to accommodate individual differences. Using a quasi-experimental design with a nonequivalent control group (N=56), students were divided into experimental and control classes. The experimental class received PBL-TaRL instruction over eight weeks (16 sessions), while the control class followed conventional teaching. Pretests and posttests were used to assess both critical thinking and learning outcomes. MANOVA results (Wilks’ Lambda = 0.029; p < 0.05) revealed significant differences, with the experimental class showing greater improvement and very large effect sizes (partial eta squared: 0.970 and 0.958). These findings demonstrate that combining PBL and TaRL fosters higher-order thinking and academic achievement by promoting active engagement and adapting materials to students’ proficiency levels. This research recommends broader implementation of PBL-TaRL within the Merdeka Curriculum and highlights the need for teacher training in task design and differentiation to maximize its impact in primary schools
TEACHERS’ BELIEFS ABOUT MATHEMATICAL PROBLEM SOLVING IN ELEMENTARY SCHOOLS : A CASE STUDY IN NUNUKAN REGENCY
No full textThis study aims to describe the beliefs of fifth-grade elementary school teachers and students regarding mathematical problem solving, as well as their approaches to teaching and learning problem-solving activities. The research employed a qualitative descriptive method, focusing on the alignment between teachers’ and students’ perceptions of problem solving within an authentic classroom context.The participants consisted of three teachers from different elementary schools in Nunukan Regency, North Kalimantan, and six students identified by the teachers three categorized as successful and three as less successful in solving mathematical problems. Data were collected through semi-structured interviews and documentation, using an interview guide developed to explore teachers’ beliefs and students’ problem-solving strategies. The validity of data was ensured through source triangulation and member checking. Data were analyzed using Miles and Huberman’s (1992) interactive model, which includes stages of data reduction, data display, and conclusion drawing. The findings revealed three main points: (1) teachers generally associated students’ problem-solving success with innate ability, while students attributed success to effort and persistence; (2) both teachers and students shared a narrow understanding of problem solving, viewing it mainly as procedural computation rather than reasoning or exploration; and (3) teachers assessed students’ success primarily based on accuracy in calculation, resulting in classroom practices that emphasized procedures over conceptual understanding.In conclusion, the study highlights the need to strengthen teachers’ pedagogical beliefs and promote reasoning-oriented instruction in mathematics classrooms. However, the limited number of participants restricts the generalizability of the findings. Future studies with larger samples and classroom observations are recommended to validate and expand these results
APPLICATION OF GAME-BASED LEARNING IN THROWING AND CATCHING LEARNING TO IMPROVE THE SOCIAL AND EMOTIONAL SKILLS OF ELEMENTARY SCHOOL STUDENTS
No full textSocial and emotional skills in elementary school students are often neglected in Physical Education, Sports, and Health subjects, because learning focuses more on motoric aspects. As a result, many students still have difficulty working together, regulating emotions, and maintaining sportsmanship when participating in physical activities. Different from previous studies that focused on improving motoric skills, this study focuses on social and emotional skills through the application of game-based learning in Physical Education, Sports, and Health. The purpose of this study is to describe the process of implementing game-based learning in learning to throw and catch a ball and its impact on the social and emotional skills of elementary school students. A descriptive qualitative approach was used in this study, with data collection techniques in the form of observation, interviews, and documentation. The subjects were fourth-grade students of SDN 2 Tente. The results showed that the application of game-based learning created an active, fun, and collaborative learning atmosphere. Active student participation increased from 63,3% to 93,3%, while the number of students who are easily angered decreased from 7 to 2 people, indicating a decrease in irritability levels of 71,4%. Improved social skills are evident in the ability to work together, communicate, and empathize, while improved emotional skills are evident in students' ability to manage emotions, accept defeat with sportsmanship, and support each other within the group. The teacher's role as a facilitator has proven crucial in guiding students in understanding character values such as sportsmanship, empathy, and cooperation. Thus, game-based learning is not only effective in improving motor skills but also contributes significantly to improving students' social and emotional skills while presenting an innovative approach to Physical Education, Sports, and Health that integrates pedagogical and psychological aspects
