This study goals to determine the extent to which the managerial competence of school principals and teacher performance influence the quality of education at State Vocational High Schools (SMKN) in Mataram City. This study applies a mixed methods approach with an explanatory sequential design involving 562 teachers from seven vocational high schools in Mataram City, with 85 teachers selected through purposive sampling. Data were acquired through questionnaires, observations, interviews, and documentation. The results indicate that principal managerial competence has a significant but small contribution on education quality, as shown by a significance value of 0.037 (< 0.05) and an effect size of 0.052. In contrast, teacher performance demonstrates a significant and moderate contribution, with a significance value of 0.000 (< 0.05) and an effect size of 0.266. Moreover, both variables simultaneously show a strong and significant contribution to education quality, supported by an F-test significance of 0.000 (< 0.05) and a combined effect size of 0.417, indicating a moderate contribution

This study was conducted to analyze the effect of suction power effectiveness on cyclones in Light Tenera Dust Separator (LTDS) 1 and 2 units on the level of palm kernel losses at PTPN IV Regional II Plantation Unit and Adolina Palm Oil Mill (POM). Palm kernel loss is a significant factor that can reduce production efficiency, as palm kernel has high economic value and is the main product in the palm oil industry. Kernel losses not only reduce production efficiency but also create significant economic disadvantages for the palm oil mill. The research method used was a gravimetric method with a field experiment approach. The research process included sampling from LTDS waste, separating kernels from shells, and measuring suction speed using an anemometer to determine cyclone performance. The gravimetric method was applied to quantify the proportion of kernel mixed with shell waste, providing measurable data on suction efficiency. The results showed that low suction power effectiveness was directly proportional to the increasing number of kernels that were thrown away with the shells. In other words, poor suction performance directly correlates with higher kernel losses. The main contributing factors include leaks in the cyclone, suboptimal blower settings, and inadequate operator skills. Operational skills and equipment maintenance were identified as crucial determinants of system performance. Based on these findings, improvements to the suction system are recommended through routine maintenance, leak checks, and blower setting calibration. Furthermore, operator training is required to precisely adjust suction power. By maintaining suction effectiveness and optimizing blower settings, kernel losses can be reduced below the standard threshold of 2.0%. Thus, mills can improve operational efficiency while minimizing economic losses due to palm kernel loss.

White-collar crime poses significant threats to corporate integrity and economic stability, particularly in emerging markets where governance structures may be less developed. This study examines the effectiveness of corporate governance mechanisms in preventing white-collar crime in emerging market contexts. Using a mixed-methods approach combining quantitative analysis of 240 publicly listed companies across five emerging markets and qualitative case study analysis of 25 corporate fraud cases, this research evaluates the relationship between governance mechanisms and crime prevention effectiveness. The study reveals that strong board independence (β = -0.312, p < 0.001), robust internal audit functions (β = -0.267, p < 0.01), and comprehensive compliance programs (β = -0.298, p < 0.001) significantly reduce white-collar crime incidence. Companies with comprehensive governance frameworks show 58% lower fraud rates compared to those with weak governance structures. The research concludes that emerging markets can significantly reduce white-collar crime through strategic implementation of governance mechanisms, particularly emphasizing board independence, internal controls strengthening, and compliance culture development.

Non-communicable diseases (NCDs) remain a leading cause of global morbidity and mortality, with chronic inflammation as a key pathophysiological mechanism. Antioxidants from fruits and vegetables have demonstrated potential to modulate inflammatory immune responses, thus contributing to NCD prevention. This study aimed to evaluate the effectiveness of fruit and vegetable consumption promotion policies in preventing NCDs by modulating inflammatory immune responses in Nabire District in 2025. The research employed a mixed-methods design, incorporating both quantitative and qualitative data from 384 adult respondents. Data were gathered through food consumption surveys, inflammatory biomarker analysis (CRP, IL-6, TNF-α), and an evaluation of policy implementation. Descriptive and inferential analyses were conducted using SPSS 28.0 and R version 4.3.0. Results revealed that average fruit and vegetable consumption in Nabire residents remained below the WHO recommended intake (289g/day vs. 400g/day), although there was a noticeable improvement compared to previous years. A significant negative correlation was found between antioxidant intake and inflammatory biomarkers (r=-0.478, p<0.001). Policy implementation reached 74% coverage with a 62% compliance rate, indicating significant improvements in reach compared to prior assessments. The study concludes that fruit and vegetable consumption promotion policies show enhanced potential in modulating inflammatory immune responses for NCD prevention.

The rapid advancement of digital technology has fundamentally transformed social structures, creating new forms of inequality and social stratification. The digital divide has emerged as a critical sociological phenomenon that reflects and reinforces existing social hierarchies while creating new patterns of inclusion and exclusion. This study examines the relationship between digital transformation and social stratification, analyzing how digital access, literacy, and participation contribute to contemporary forms of social inequality. The research investigates the mechanisms through which digital divides reproduce and transform traditional class structures. This sociological inquiry employs a mixed-methods approach, combining quantitative survey data from 500 households across different socioeconomic strata with qualitative ethnographic observations and in-depth interviews with 40 participants. The study utilizes Pierre Bourdieu's theory of capital and Anthony Giddens' structuration theory as analytical frameworks. The findings reveal three distinct digital classes: the "digitally privileged" (25%), "digitally struggling" (45%), and "digitally excluded" (30%). Digital capital significantly correlates with traditional forms of capital (economic, cultural, and social), creating compound advantages for privileged groups. The study demonstrates that digital transformation both reinforces existing inequalities and creates new forms of social differentiation. Digital transformation has become a new dimension of social stratification that intersects with traditional inequality patterns. The digital divide represents not merely a technological gap but a fundamental social divide that requires comprehensive sociological understanding and policy intervention to ensure equitable social development.

This study examines the impact of bureaucratic reform through merit system implementation on political elite behavior and patronage politics practices in regional government. Using a mixed-method approach combining quantitative analysis of 150 regional governments and qualitative case studies in five provinces during 2019-2024, this research investigates how civil service recruitment reforms influence transactional political practices. The study employs New Public Management theory, political patronage theory, and institutional change theory to analyze the transformation of elite behavior. Results indicate that merit system implementation significantly reduces political patronage practices (β = -0.627, p < 0.001), with stronger effects in regions with higher institutional capacity and civil society oversight. However, political elites adapt by shifting patronage mechanisms from recruitment to procurement and project allocation. The study reveals that successful bureaucratic reform requires simultaneous strengthening of transparency mechanisms, political accountability, and civil society participation. These findings contribute to understanding the complex relationship between administrative reform and political behavior change in decentralized governance systems.

The development of science and technology has caused the military forces of many countries to spend a lot of money and energy on research and development of automated, multi-faceted and effective (including lethal) technology. From a maritime perspective, this development has attracted widespread interest from many navies in underwater technology such as submarines and unmanned submarines. Modern submarines are now capable of moving at high speeds with very low noise levels, in addition to being able to carry weapons with very high destructive power and carry out diving operations for long periods of time. At the same time, modern unmanned underwater vehicles are now capable of carrying out various types of operations, including surveillance, minelaying, underwater surveys, and even the ability to carry long-range weapons up to thousands of kilometers away. It is undeniable that the development of other countries' navies is a real threat to Indonesia. To overcome this problem, an underwater surveillance system is needed in Indonesian waters, especially in deep waters which are likely to be used by other countries such as ALKI to carry out covert operations. This underwater surveillance system must utilize existing technological developments in order to carry out its functions effectively and sustainably, especially by using autonomous underwater vehicles (USVs). The use of USV in surveillance systems will save a lot of costs because it does not waste budget on expensive logistics, personnel, maintenance, and spare parts. This research is a research and development using mixed research methods (qualitative and quantitative) with research products in conceptual form. In this underwater surveillance system concept, USV will automatically conduct underwater contact surveillance along the ALKI II water body using sensors and software integrated into the USV.

This research aims to analyze optimal educational strategies for cadets of the Indonesian Navy Academy's Technical Corps Generation Z, considering their unique learning characteristics without compromising military values. Using a mixed-method approach with a sequential explanatory design, the research involved 180 cadets as quantitative respondents and 26 participants for the qualitative phase (15 cadets, 8 instructors, 3 AAL leaders). Data were collected through structured questionnaires, in-depth interviews, focus group discussions, and participatory observations. Quantitative analysis used descriptive statistics, comparative tests, and multiple regression, while qualitative data were analyzed thematically. The results show that Generation Z cadets have a preference for visual learning (68%), interactive technology-based learning (M=4.1), and require instant feedback. Blended learning proved to be the most effective with an GPA of 3.45 and an engagement rate of 85%, compared to traditional learning (GPA=3.18, engagement=61%). Predictor factors of learning effectiveness include interactivity (β=0.412), technology use (β=0.298), periodic feedback (β=0.267), and content relevance (β=0.231). The research produced the "ADAPTIVE" learning model, which integrates modern technology with traditional military values. This model can enhance educational effectiveness while maintaining the essence of military training, providing both theoretical and practical contributions to the transformation of military education in the digital era.

The purpose of this research is to analyse the legal status of children born from marriages of different nationalities in the perspective of Indonesian Civil Law and Islamic Law. This research is important because children born from mixed marriages are entitled to protection of their legal status in order to maintain the continuity of life, legal position and civil interests. The research method used is normative juridical legal research with qualitative data types in the form of secondary data consisting of primary legal materials, secondary legal materials and tertiary legal materials relevant to the topic of this research and data collection techniques using library research or literature studies with legal material analysis techniques using descriptive analysis methods. The results of this study state that the law of marriage between different nationalities in the perspective of Indonesian civil law and Islamic law raises problems with the law of marriage itself as well as the legal status, civil rights and citizenship rights of children. In the perspective of Indonesian civil law and Islamic law, the law of marriage of different nationalities is a valid marriage and the legal status of the child is a legitimate child, the civil rights of children from marriages of different nationalities are the same as children in general and the legal status of the child's citizenship as an Indonesian citizen follows the citizenship of the father or mother who is an Indonesian citizen and can also have dual citizenship until he is 18 years old or married, after which the child must declare choosing one of his citizenship.

This study examines the portrayal of existentialist principles and characterization in Final Destination 5 (2011), directed by Steven Quale. The research aims to identify the methods of characterization used for the five main characters and explore how Sartrean existentialism is reflected in their struggles. Using a qualitative approach, the study applies Kenney’s method of characterization and Sartre’s existentialist framework to analyze key scenes, dialogues, and character interactions. Data was collected through repeated viewings of the film, with critical moments transcribed and categorized based on characterization methods and existential principles. The findings reveal that Final Destination 5 employs a mixed method, with the dramatic method being the most dominant, supplemented by character on other characters and contextual methods to develop psychologically complex main characters. Existentialist principles emerge strongly, particularly the idea that "existence precedes essence," as characters are stripped of predefined roles and forced to define themselves through desperate actions. The burden of freedom and responsibility is evident in moral dilemmas, while the confrontation between anguish and authenticity shapes their responses to impending death. Sam’s journey from fear to acceptance exemplifies Sartrean authenticity, whereas Nathan’s ethical crisis highlights the paradox of human freedom.
