Language is closely related to social and cultural aspects, including in the process of learning foreign languages such as Mandarin. Effective Chinese language learning does not only focus on linguistic aspects, but also requires an understanding of the culture of origin of the language. The purpose of this paper is to analyse the application of culture-based learning in increasing motivation to learn Chinese. The method used is literature study or library research, with documentation technique as data collection method and content analysis technique as data analysis method. Based on the analysis of twelve research articles, it was found that the integration of cultural elements such as traditional games, visual media, and Chinese pop culture can create a learning experience that is fun, interesting, and encourages students' curiosity towards Chinese. In conclusion, culture-based learning is proven to have a positive influence on motivation to learn Chinese and can be used as an alternative teaching strategy that is more contextual and fun.

This study aims to analyze the marketing strategies, operational mechanisms, and key challenges faced by the Multipurpose Cooperative (KSU) BONA MANDIRI JAYA. A qualitative research approach was employed, utilizing in-depth interviews, direct observation, and document analysis as data collection methods. The results show that the cooperative adopts a direct marketing strategy targeting underserved and remote areas, combined with a personalized approach in monitoring its clients. Despite its growth, the cooperative encounters several challenges, including limited capital, low member financial literacy, non-performing loans, and the need to adapt to digital transformation.

The study recommends strengthening institutional capacity and adopting digital systems to enhance the sustainability and efficiency of cooperative operations.

This paper discusses the impact of the Sudanese refugee crisis on security stability in the Chad border region. The conflict between the Sudanese Armed Forces and Rapid Support Forces since April 2023 has triggered a massive wave of refugees, making Chad one of the main recipient countries. Using a regional security complex theory approach, this paper shows that the flow of refugees not only creates social and economic pressures, but also magnifies security risks such as infiltration of armed groups, tensions between communities, and weak control in the border region. Through document analysis, the paper highlights how Chad's capacity constraints exacerbate the situation, as well as the need for a long-term response involving cross-actor coordination and sustained international support.

This paper explores how climate change has contributed to the armed conflict in Darfur, Sudan, by emphasizing the human security perspective. Prolonged drought, desertification, and resource scarcity have intensified tensions between farming and pastoralist communities. Using a case study method and the Human Security framework, this study finds that ecological stress acts as a threat multiplier in conflict-prone areas. Data from IPCC, SIPRI, and UNHCR reports highlight how environmental degradation worsens structural vulnerabilities and fuels horizontal violence. The analysis shows that climate change is not only an environmental issue but also a serious security concern in fragile states. The failure of state institutions to equitably manage natural resources exacerbates the crisis. Therefore, a long-term, multi-sectoral policy response is urgently needed. Integrating climate resilience into international security strategies is essential to protect basic human rights.

Economic development in today's world has grown rapidly, leading to numerous changes in human life. By investing in the capital market, it becomes one of the alternatives for financing the community's economy and is easily accessible to the public. One of them is to invest in bond securities in issuer companies. However, by purchasing bonds in the capital market with the issuer company, in addition to providing benefits through interest rates, there are risks, including if the issuer company goes bankrupt. Under these conditions, the holder of the unsecured bond will be positioned as a concurrent creditor, whose repayment is made after the separatist and preferred creditor. Although not guaranteed collateral, bondholders still obtain legal guarantees of their rights through information disclosure, the role of trustees, and arrangements within the applicable legal framework.

This study was motivated by the low learning outcomes of students in Physics subjects in class XII MIPA 7 at SMAN 1 Cikalongwetan, where most students had not reached the minimum mastery criteria. The purpose of this research was to improve student learning outcomes through the implementation of the Problem-Based Learning (PBL) model. The study employed a Classroom Action Research (CAR) method conducted in two cycles, each consisting of two meetings. Each cycle included planning, action, observation, and reflection stages. Data were collected through observations and written tests. The results showed an improvement in student learning outcomes after the implementation of the PBL model, as indicated by the increased number of students achieving scores above the minimum standard and a higher percentage of overall mastery. These findings suggest that the Problem-Based Learning model can be an effective solution to enhance student achievement in Physics. The implication of this study emphasizes the importance of the teacher’s role in designing student-centered learning and facilitating critical thinking and problem-solving skills.

Maritime security is a strategic issue in Southeast Asia due to the high dependence of ASEAN countries on sea lanes for trade and regional stability. This study aims to analyze Indonesia's role in strengthening maritime security cooperation in ASEAN. The methods used are literature studies and analysis of policy documents related to ASEAN maritime cooperation and national maritime policies. The results of the study show that Indonesia is active in various regional forums such as the ASEAN Maritime Forum (AMF) and the Expanded ASEAN Maritime Forum (EAMF), and carries the Global Maritime Fulcrum (GMF) initiative. Despite challenges such as overlapping institutional authority and limited resources, Indonesia continues to demonstrate a strong commitment to promoting maritime diplomacy, strengthening governance, and handling issues such as IUU Fishing and the South China Sea conflict. The implications of this cooperation are increased regional stability and strengthening ASEAN's position in facing the geopolitical dynamics of the Indo-Pacific.

This study investigates the effectiveness of Cognitive Behavioral Therapy (CBT) in reducing neurotic symptoms among young adults. Neurotic disorders, characterized by excessive anxiety, emotional instability, and psychosomatic complaints, often affect university students during transitional periods. Using a quasi-experimental pretest-posttest control group design, 30 participants were divided equally into an experimental group receiving six sessions of CBT and a control group receiving no treatment. Data were collected through a validated neurotic disorder scale and analyzed using paired and independent sample t-tests. Results revealed a significant decrease in neurotic symptoms in the experimental group after the intervention, while the control group showed no meaningful change. The findings support the use of CBT as an effective therapeutic approach for reducing neurotic symptoms through cognitive restructuring and adaptive behavioral training. This research highlights the relevance of culturally adapted CBT in university counseling settings and encourages the development of structured group programs to address mental health issues among young adults. Further studies are recommended to explore broader applications across diverse populations and institutional contexts.
