Abstract

Purpose: This study analyzes the effectiveness of investigations into Sailing Approval (SPB) violations conducted by the Ditpolairud Riau Islands Police. It seeks to evaluate how well current law enforcement mechanisms ensure maritime safety and legal compliance under the Navigation Law. Research methodology: The research employs a normative and empirical juridical approach. Data were collected from legislation, literature reviews, and in-depth interviews with investigators, Syahbandar officials, and maritime business operators. The findings were validated through triangulation and analyzed descriptively using John Rawls’ Theory of Justice, Friedman’s Legal System Theory, and Sudikno Mertokusumo’s Legal Certainty Theory. Results: Investigations into SPB violations have been carried out in accordance with legal procedures, including coordination between Ditpolairud, Syahbandar, PPNS, and prosecutors. While enforcement actions have increased compliance, several challenges remain, such as limited resources, overlapping authority, legal gaps, maladministration, and low awareness among shipowners and fishermen. Digitalization of SPB documents and improved transparency in service fees were identified as key solutions. Conclusions: The investigations are generally effective but still constrained by structural, substantial, and cultural barriers. Effective enforcement requires harmonized regulations, institutional synergy, technological integration, and public legal awareness to ensure maritime safety and compliance. Limitations: This study is limited to the jurisdiction of the Riau Islands and relies on qualitative field interviews, without quantitative assessment of enforcement outcomes. Contribution: The study contributes to maritime law by emphasizing justice, legal certainty, and system effectiveness in SPB investigations, while offering recommendations to improve institutional capacity, transparency, and regulatory alignment.

Abstract

Cardiorespiratory capacity and motor efficiency are crucial for athlete performance under extreme fatigue. This descriptive quantitative meta-analysis aims to analyze the effectiveness of caffeine as an ergogenic aid on physical and psychomotor performance. Secondary data were drawn from five reputable scientific literatures with controlled experimental designs in badminton, soccer, hockey, karate, and cognitive function. The synthesis of results shows that caffeine significantly increases aerobic endurance ($p < 0.05), maintains skill stability under fatigue, and improves accuracy and reaction time. Neurophysiologically, caffeine blocks adenosine receptors in the central nervous system to delay the perception of fatigue and stimulates calcium release in the sarcoplasmic reticulum to strengthen muscle contractions. An optimal dose of 3–6 mg/kg body weight consumed 45–60 minutes before activity has been shown to be valid, legal, and effective in delaying central/peripheral fatigue and boosting performance by 2–3%. Further research is needed to examine the variability in individual responses based on genetics and caffeine habituation.
