Abstract

Bullying in schools causes serious psychological and academic impacts on students. Legal education on child protection serves as a preventive strategy that can raise students’ awareness of children’s rights and the consequences of bullying, while also supporting the implementation of Child-Friendly School programs. This study aims to examine the effectiveness of legal education on child protection in improving students’ knowledge, attitudes, and behaviors related to bullying at SMK Negeri 12 Medan. The study employed a mixed methods approach with a sequential explanatory design. Quantitative data were collected from 80 students in grades X and XI using questionnaires administered before and after the educational intervention, while qualitative data were obtained through interviews and observations. The legal education was conducted in four structured sessions covering the definition of bullying, children’s rights, behavioral boundaries, and legal sanctions. Quantitative data were analyzed using descriptive statistics and bivariate tests, whereas qualitative data were analyzed thematically. Before the intervention, 56.25% of students lacked knowledge of the Child Protection Law and the consequences of bullying. After the intervention, 62.5% of students demonstrated good knowledge, with a p-value of 0.003 (<0.05), indicating a significant improvement. Observations and interviews revealed increased empathy, social responsibility, and active participation in creating a safe and inclusive school environment. Legal education on child protection effectively enhances students’ knowledge, awareness, and anti-bullying attitudes, supports the implementation of Child-Friendly School programs, and emphasizes the importance of legal literacy as a practical strategy for preventing bullying in schools.

Abstract

Irrigated rice fields serve as the primary land for rice production. Whether continuous rice cultivation or alternating with secondary crops, the cropping pattern in these filelds depends on water supply. These differences in cropping patterns will affect the soil's nutrient dynamics and rice productivity. This research aims to analyze the soil fertility dynamics and rice productivity in irrigated rice fields under different cropping patterns. The study used an oversite design with two factors, namely cropping patterns (rice-rice-rice (R-R-R), rice-rice-corn (R-R-C), and rice-rice-soybean (R-R-S)), and superior varieties (Inpari 23 and Mentik wangi). The results showed that the overall fertility of irrigated rice fields was low, with crucial limiting factors being deficiencies in total N, available P, and K nutrients. Differences in cropping patterns on Inceptisol significantly affect available P. The R-R-R cropping pattern, including the Inpari 23 and Mentik wangi varieties, provided the highest productivity, reaching 6.5-6.9 t ha-1. Selecting the right superior varieties and those by cropping patterns can increase the dry milled grain (MDG) yields by 23.52-30.1% compared to other superior varieties. Sufficient water availability throughout the growing phase can increase rice productivity by 33.3 -56.2% (1.5-2.3 times). Therefore, the key to intensive rice field management is not only to pay attention to soil fertility (nutrient dynamics), fertilization (organic and inorganic), and pest and disease control, but also to ensure the availability of sufficient water during cultivation and to use superior varieties. This research is beneficial for farmers, stakeholders, and the government in efforts to increase food security.
