This study aims to examine the effectiveness of the LingoDeer application as a learning medium for basic level Japanese language learners. A quantitative approach was employed using a One Group Pretest Posttest design involving 50 students from the Vocational School of IPB University. The research instrument consisted of pretest and posttest assessments focusing on three key areas: vocabulary, grammar, and reading skills. Based on the results of the paired sample t-test, a significant improvement was found in all aspects after the use of the application, with the average score increasing from 60.97% to 81.25%. The greatest improvement was observed in vocabulary, followed by reading and grammar. These findings suggest that LingoDeer, with its structured learning system, spaced repetition feature, and interactive exercises, can effectively support the development of Japanese language skills at the beginner level. This study is expected to serve as a reference for educators in selecting appropriate technology-based learning tools to enhance language acquisition.

Micro, Small, and Medium Enterprises (MSMEs) have a significant role in the economy, including MSMEs in the culinary sector such as Putri Ice Cream Business. Decision making related to optimal resource allocation is crucial to increase the efficiency and profitability of MSMEs. This study aims to apply the linear programming method with the primal simplex algorithm to minimize production costs in the case study of Putri Ice Cream MSME. The objective function is to minimize the total production cost, as well as the limitations related to the availability of main raw materials and machine production capacity. Data on main raw materials and machine production capacity were obtained from the Putri Ice Cream MSME which was the case study. The results of the study show that the application of the primal simplex method produces an optimal solution that provides recommendations for product combinations for each type of Putri Ice Cream with minimal production costs. Sensitivity analysis was also conducted to test the stability of the optimal solution to changes in capital. This study provides a practical contribution to Putri Ice Cream MSME in optimizing their resource allocation and increasing cost efficiency through a quantitative approach.

Thus Ha, namely there is a positive and significant influence of the discussion method on the interest in learning Christian Religious Education of class XI students of SMA Negeri 1 Sipoholon in the 2024/2025 Academic Year, is accepted and H0 is rejected.

Discipline character education in early childhood refers to instilling obedience to rules at home, school, and in society for children aged 0–6 years. This education serves as a crucial foundation for shaping future generations. This study aims to examine the implementation of traffic ethics education for young children, the strategies used, and influencing factors at Al-Anshor Islamic Kindergarten Palembang in the 2023/2024 Academic Year. A qualitative descriptive method was employed, involving two teachers (Class A and B) as the main data sources. Data were collected through observation, interviews, and documentation. The findings reveal that the strategy for teaching traffic ethics includes: (1) Planning, by integrating traffic ethics indicators into RKM and RPPH; (2) Implementation, through integration in learning activities, school culture, and daily routines; and (3) Evaluation, conducted in conjunction with other learning assessments. The character values fostered through this process include self-confidence, discipline, and responsibility. These findings suggest that incorporating traffic ethics education into early childhood learning can effectively instill discipline, contributing positively to children's character development and awareness of civic responsibility from an early age.

Indonesia, which is located on the equator, has great potential to utilize solar energy, with an average solar radiation reaching 4.80 kWh/m² per day. This provides an advantage in the development of Solar Power Plants (SPP), one of which is through the installation of rooftop on the roof of the building as a source of electrical energy. This study aims to analyze the feasibility of SPP development by considering the techno-economic aspects of the Pondok Juice cafe. The total real electrical energy consumption required by the Pondok Juice cafe is 32,548 Wh/day. Assuming a system loss of 15%, the total electrical energy requirement that must be supplied by the SPP is 37,430.2 Wh/day. The initial investment projection is IDR 204,265,197, with operational and maintenance costs for 25 years of IDR 105,760,028. The investment feasibility analysis shows NPV of IDR 441,523,820.10, BCR 4.11, DPP ±5 years, and IRR 15.55%, which proves that this SPP planning is feasible to implement.

This study aims to analyze the influence of Resource-Based View (RBV) on innovation performance in Micro, Small, and Medium Enterprises (MSMEs) that have expanded internationally, with government information access as a moderation variable. This study uses a quantitative approach with the Partial Least Squares Structural Equation Modeling (PLS-SEM) method. The object of the research is CV. Delta Raya, an MSME in the furniture sector from Batu City that has successfully penetrated the export market to Japan, South Korea, and Mexico. The results of the study show that human capital investment and political connections have a significant positive effect on innovation performance. Although international experience does not have a direct effect, the effect becomes significant when moderated by government information access. Access to government information also strengthens the influence of political connections on innovation. The implications of this study underscore the importance of collaboration between MSME actors and government institutions in encouraging internal resource-based innovation.
