Abstract

This research aims to analyze the accountability and transparency of financial assistance provided to political parties in a regency. The study employs observations and documentation to enhance data accuracy. Accountability is assessed using Koppell's four dimensions, while transparency is evaluated through Bovens' three perspectives. The findings reveal that accountability for political party financial assistance in the regency is weak, largely due to the lack of government oversight, which increases the risk of budget mismanagement or diversion. The roles of the Audit Board (BPK) and the Regional Government are limited to auditing, guiding, and monitoring, without any control over the financial assistance given to political parties. Furthermore, political parties have not fully complied with the requirements for submitting accountability reports. In terms of transparency, political parties receiving financial assistance have not effectively implemented transparent practices. There is a tendency for political parties to restrict access to financial information, limiting it to political circles, making it difficult for the public to obtain details about party performance. Additionally, the legal framework established by the government lacks sanctions for non-compliance with transparency requirements, which hinders the achievement of the intended level of public transparency.

Abstract

Lakepe (Betta raja) is a wild fish species inhabiting water region in Labuhanbatu regency. The fishes are commonly known to inhabit steady and unpolluted streams. The aquatic environmental condition and its ecology will determine the survivability and breeding of Betta raja in its natural habitat.A study of its ecological aspect is needed to obtain any physicochemical characteristics of natural habitat which may act as limiting factor to Betta raja presence. In this study, physicochemical characteristics of water are measured, i.e temperature (T), velocity, pH, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solid (TDS), and total suspended solid (TSS). The environmental condition are measured in the field (in situ) while other parameters, i.e DO, BOD, TDS, and TSS are analyzed in the laboratory. The results showed that the physicochemical characteristics of B. raja habitat are: T (26oC), velocity (0.05 m/s), DO (6.9 mg/L), BOD (3.27 mg/L), COD (8.26 mg/L), TDS (22.1 mg/L), and TSS (5.1 mg/L). The sizes of wild caught B. raja are ranged between 6.3–94.0 cm with body masses of 1.1–4.8 g.

Abstract

In the contemporary cybersecurity landscape, the attack paradigm shift from exploiting technical vulnerabilities to manipulating human psychology (social engineering) has reached a critical level. The 2024 and 2025 annual reports from various global and national security authorities indicate that traditional defense mechanisms centered on the technical perimeter are no longer sufficient to stem the tide of attacks targeting the user's cognitive layer. This paper proposes the development and formalization of a new mitigation protocol, TEBAS (Research, Evaluation, Block, Secure, Deliver). This protocol was designed using the Design Science Research (DSR) methodology to address the specific needs of Indonesia's digital ecosystem, characterized by a highly communal culture but facing a significant digital literacy gap. TEBAS integrates human-centric cybersecurity principles with global standard frameworks such as the NIST Cybersecurity Framework 2.0, but is adapted into operational procedures that can be implemented by individuals and communities. Through an in-depth analysis of current attack vectors such as Quishing (QR Code Phishing) and Deepfake Vishing, and validation using a modified Delphi method, this study demonstrates that TEBAS offers a holistic approach that focuses not only on individual detection but also on collective resilience through a community-based intelligence-sharing mechanism ("Convey").

Abstract

This study presents a Calculus-based framework for calculating conversion efficiency in power electronics modules, with emphasis on the integration of MATLAB/Simulink for modeling and validation. The main objective is to formulate the dynamics of efficiency using differential calculus, and to optimize conduction paths and converter topology through vector calculus and variational calculus. The methodology includes mathematical modeling based on differential equations to capture conversion dynamics, transient analysis via signal processing, and optimization algorithms grounded in calculus of variations to minimize conduction losses, switching losses, and thermal losses. Validation is performed through numerical simulations in MATLAB/Simulink and experimental testing on DC-DC converter and inverter prototypes under diverse loading and temperature conditions. Initial results indicate that the calculus-based approach enhances the accuracy of efficiency estimation and provides clearer insights into the trade-offs between converter topology and operational load. The study concludes by highlighting the potential of calculus-based techniques for designing more efficient power modules and offering recommendations for topology exploration and parameter optimization under varying thermal environments. Keywords: calculus, algorithms, MATLAB, Simulink, efficiency, power module, DC-DC converter, vector calculus, transient analysis.
