Abstract

This study examines the influence of intrinsic motivation and parenting style on personality stability among students at the Defense University. Personality stability is a crucial component in shaping resilient, consistent, and adaptive character, especially in a military educational environment that demands a high level of discipline. Intrinsic motivation is defined as the internal drive to engage in activities perceived as meaningful, enjoyable, and challenging. Meanwhile, parenting style, whether delivered by regimental caregivers or peer mentors (senior cadets), plays a vital role in shaping the attitudes and behaviors of students. Emotional stability reflects an individual's ability to process and express their emotions in a manner consistent with their developmental stage. This research employed a quantitative approach using a multiple linear regression design. The population consisted of 250 students, with 153 active students selected as the sample. Data were collected using a Likert-scale questionnaire that measured the variables of intrinsic motivation, parenting style, and personality stability. The findings revealed that intrinsic motivation and parenting style simultaneously significantly influence personality stability, with a standardized coefficient of 0.83 and a t-value of 18.59. Intrinsic motivation alone had a significant effect, with a coefficient of 0.71 and a t-value of 12.29, whereas parenting style had a significant effect, with a coefficient of 0.18 and a t-value of 3.23. These results reinforce the importance of autonomy, competence, and relatedness, and support the two-dimensional parenting theory. The study also highlights the significant roles of permissive and authoritarian parenting styles within the military university context. This research provides theoretical contributions to the development of personality and motivation in higher education, particularly in military academic environments. The findings serve as a basis for institutions to design learning strategies and character-building programs that promote intrinsic motivation and support the development of a stable personality. This study also provides a foundation for future psychosocial interventions and initiatives aimed at enhancing student character.

Abstract

This study investigates the long-term relationship and causal dynamics among military expenditure, economic growth, and exchange rate in Indonesia over the period 2000-2023 to provide empirical insight into whether defense spending functions as a catalyst for economic growth or merely reflects the country’s fiscal capacity. Using annual time-series data from the World Bank’s World Development Indicators, the analysis applies the Johansen cointegration and Granger causality tests to assess both equilibrium and directional linkages. Before estimation, all variables are expressed in natural logarithms and subjected to the Augmented Dickey–Fuller test to ensure robustness of the empirical results. The findings confirm one significant cointegration relationship, indicating a stable long-term relationship among the variables. Granger causality results identify a unidirectional causality from economic growth to military expenditure, and from military expenditure to the exchange rate. These findings suggest that Indonesia’s defense spending is primarily responsive to fiscal capacity while influencing exchange-rate stability. The study contributes to the defense economic literature by integrating defense spending with economic development strategies through domestic procurement, fiscal efficiency, and the strengthening of strategic industries to maximize multiplier effects on economic growth and maintain macroeconomic stability.

Abstract

This study analyzes the relationship between research and development (R&D) investment in the defense sector and the autonomy of Indonesia’s national defense industry. Employing a qualitative approach based on a literature review and document analysis, this study examines theoretical frameworks, policy instruments, and empirical practices in Indonesia and selected comparator countries, including the roles of institutions such as KKIP, BRIN, and the Ministry of Defense. The main findings indicate that defense R&D investment plays a critical role in building technological capacity, strengthening domestic supply chains, increasing the local content ratio (TKDN), and promoting import substitution and technology transfer. However, key challenges persist, including limited funding, policy fragmentation, and underdeveloped human resources in defence R&D. Case studies of state-owned defense enterprises (PT Pindad, PT PAL, PT DI) illustrate the dynamics of innovation, international collaboration, and resulting economic multiplier effects. The study concludes that the success of defense R&D investment is highly dependent on policy synergy, sustainable funding, a robust innovation ecosystem, and developing high-quality human capital. Policy recommendations emphasize the need to increase R&D budget allocations, optimize triple helix collaboration, and implement regulatory reforms to accelerate the autonomy of the national defense industry.

Abstract

The defense industry has a strategic role in supporting Indonesia's economic independence and national security. Companies such as PT Pindad, PT Dahana, and PT INTI are the main actors in providing defense equipment, explosives, and strategic communication technology. However, financial and operational challenges still hamper their contribution to defense economic independence. This study aims to evaluate the financial performance of the three companies in the 2019-2023 period with a focus on financial performance evaluation analysis. The research method uses a quantitative descriptive approach based on secondary financial data. The results show that PT Pindad and PT Dahana experienced a significant increase in net profit in 2023, amounting to IDR 120.77 billion and IDR 458.46 billion respectively, after facing fluctuations during the study period. In contrast, PT INTI continued to record losses from 2019 to 2023, with the largest loss reaching Rp 434.77 billion in 2019. This finding indicates a significant difference in the company's ability to overcome financial challenges. The implications of this study highlight the importance of strengthening managerial strategies, operational efficiency, and government policy support to sustainably increase the defense industry sector's contribution to national economic independence.
