Abstract

A Conventional statistical inference often relies solely on the use of p-values, thereby overlooking the practical significance of results, particularly in categorical data analysis, where the reporting of effect sizes is frequently neglected. This study aims to evaluate the application of proportion hypothesis tests in five scenarios (one Population to k dependent and independent populations) by integrating manual calculations, effect size estimates, and post-hoc tests. The research method involved deconstructing the Z, McNemar, Chi-Square, and Cochran's Q test formulas, which were compared with effect metrics including Cohen's g, Cohen's h, Cramer's V, and Serlin's . The results of the analysis reveal an apparent discrepancy between statistical and practical significance. In the one-population test, statistically significant results (p < 0.05) turned out to have a negligible effect (Cohen's g = 0.12), whereas in the Cochran's Q test, the threshold p-value (p = 0.0497) was reinforced by a substantial effect size (Serlin's R² = 0.30). This study concludes that integrating omnibus tests with post-hoc procedures (such as Marascuilo and Pairwise McNemar) and reporting effect sizes is imperative to avoid misleading binary interpretations and enhance the validity of scientific conclusions. The main contribution of this paper is providing a consolidated, practical framework for researchers to transition into the "New Statistics" paradigm when dealing with diverse categorical data structures.

Abstract

Background: In Indonesia, the treatment of the phenomenon of Possession Trance Disorder (PTD) and visual hallucinations is often hampered by the dichotomy between medical and spiritual approaches. Many interventions fail because they rely solely on theoretical assumptions without sufficient empirical field evidence. Objective: This study aims to dissect the etiology, mechanisms, and effectiveness of mystical phenomena therapy using primary data (case studies and experiments) and to formulate integrative intervention models and methods. This study was conducted using the Systematic Review of Primary Studies method, following the PRISMA 2020 protocol. Inclusion criteria are strictly limited to primary data articles (case studies, qualitative field studies, EEG experiments) published between 2019 and 2025. Results: Analysis of 15 selected primary studies showed that PTD consistently appeared as a comorbidity of undiagnosed dysthymia and trauma. Neurophysiological evidence (EEG) confirms that trance is a biological hyperarousal condition, not just hysteria. Therapies based on Indigenous Psychology (Kawruh Jiwa) and cultural distraction techniques (Drawing/Murottal) have proven effective in real clinical settings. Conclusion: The most effective treatment model is an integrated approach or hybridization: medical biological stabilization combined with the restructuring of meaning through local psychology.

Abstract

This study presents a critical, in-depth, and comprehensive analysis of the policy architecture, business model, and strategic implications of the Red and White Cooperative (KMP) program launched by the Government of Indonesia for the 2024-2029 period as the central pillar of people's economic transformation. Under the legal umbrella of Presidential Instruction Number 9 of 2025, this program targets the establishment and revitalization of 80,000 cooperative units as rural economic aggregators, vitally integrated with the Free Nutritious Meal Program (MBG). This study uses a qualitative approach, with a policy case study design, enriched by a systematic literature review and a global comparative analysis. The analysis was conducted through a multi-theoretical lens that included New Institutional Economics to dissect the structure of transaction costs; Institutional Isomorphism from DiMaggio and Powell to evaluate regulatory pressures and the risks of uniformity without substance; Stewardship Theory for aspects of managerial motivation; and the concept of Platform Cooperativism to examine digital sovereignty. The study's findings show that integrating KMP as a Nutrition Fulfillment Service Unit (SPPG) creates a captive market, which is crucial for initial cash flow. However, risk analysis reveals the potential for coercive isomorphism, which can give rise to "shell cooperatives" if it is not accompanied by strengthened social capital and member autonomy. Comparative studies of the Zen-Noh federation model in Japan and the Mondragon Corporation innovation ecosystem in Spain recommend restructuring from an atomistic model to a strong vertical federation, as well as the institutionalization of cooperative education to ensure long-term sustainability free from state dependence
