Purpose: Public service transformation is pivotal for enhancing urban community welfare. Through innovative strategies, technology, and community engagement, this effort aims to deliver services that are more efficient, responsive, and aligned with community needs. Method: Employs quantitative methods, utilizing Structural Equation Modelling (SEM), to explore the dimensions and potential impacts of this transformational journey. Finding: The study on public service transformation in Bandung City highlights the significance of enhancing community welfare through improved quality of life, increased public satisfaction, and strengthened government trust. The transformation has improved access to services, reduced complaints, and boosted public perception of service quality. Emphasis on transparency, accountability, and data security has fostered public trust. The government’s success in meeting community needs underscores the importance of public service transformation in promoting shared prosperity.

This article argues that neoliberalism and patriarchy are interconnected in creating academic precarity for early-career women academics in Indonesia. It examines state-promoted higher-education policies that advance neoliberalisation through discourses of self-reliance, competitiveness, and entrepreneurship, with particular attention to self-reliance, which has emerged as the most significant aspect of early-career academics' lives. Under patriarchy, women are often burdened with responsibilities for childcare and domestic chores. Drawing on Michel de Certeau's concept of 'making do', this article analyses how Indonesian early-career women academics navigate academic precarity to construct their self-imagined careers. Our analysis of 13 interviewees shows that these scholars respond to academic precarity by engaging in side hustles and leveraging online work, taking steps to navigate precarious academic careers, and negotiating informal support systems to handle precarious personal relationships. Although the participants did not explicitly mention feminism, their everyday practices embody feminist values. The article thus concludes that 'making do' is an individual tactic, while collective academic practice is needed.

IDChat (Internet-Dependent Cryptographic Hybrid Authentication Technology) is a universal digital identity framework designed to eliminate costly and vulnerable SMS-based one-time passwords (OTPs). It fuses civil identity (NIK), multi-biometric modalities (fingerprint and retina), and genomic-derived entropy to reinforce cryptographic key generation under a unified fusion engine. Targeting Indonesia’s 120 million internet users—90% of whom still rely on paid SMS OTPs—IDChat introduces a privacy-preserving Digital Genetic Signature (DGS) generated via SHA-256 hashing and homomorphic encryption (BFV scheme), enhancing resistance to spoofing and brute-force attacks. Experimental validation using OpenCV with FVC2004 and CASIA-Iris datasets achieved 99.1% authentication accuracy, a false acceptance rate (FAR) of 0.008%, and an average latency of 1.9 seconds, demonstrating competitive efficiency against existing biometric systems. A comparative cost analysis indicates potential national savings of Rp 12–50 trillion annually by replacing SMS OTPs with free Wi-Fi–based verification. Unlike centralized frameworks such as Aadhaar or FIDO2, IDChat performs local (offline) verification within closed Wi-Fi environments through cached encrypted templates, ensuring independence from cellular networks. DNA information functions as a static entropy factor enrolled once during registration, avoiding any real-time biological sampling. This study presents the first technically validated multi-biometric and DNA-derived cryptographic fusion model optimized for secure, inclusive, and cost-efficient digital authentication in resource-constrained environments.

Hypertension remains a major global health burden, with angiotensin converting enzyme (ACE) representing a central therapeutic target in blood pressure regulation via the RAAS. Although synthetic ACE inhibitors are clinically effective, their long-term use is frequently associated with adverse effects, motivating the search for safer alternative agents. Piper betle L. is a medicinal plant rich in diverse bioactive phytochemicals with reported cardiovascular benefits. This study aimed to systematically evaluate the ACE inhibitory potential of Piper betle leaf constituents using an integrated in silico approach. A total of 43 compounds were docked against human ACE (PDB ID: 1UZF) using the PLANTS algorithm, with protocol validation performed by captopril redocking. Binding affinities and key interactions were analyzed, followed by prediction of physicochemical properties, drug-likeness, and toxicity using ADMETlab 3.0 and ProTox-3.0. Docking results revealed that several compounds, including cerebrosides, lignans, and long-chain esterified phenolics, exhibited strong predicted binding to ACE. However, many high-affinity ligands showed unfavorable physicochemical characteristics, low quantitative estimates of drug-likeness, and multiple medicinal chemistry rule violations. In contrast, Piperenamide A and Piperenamide B demonstrated a balanced profile, combining stable ACE binding with favorable physicochemical properties, compliance with Lipinski’s Rule of Five, and low predicted toxicity. Simple phenolic compounds displayed good safety profiles despite moderate binding affinity. Overall, this integrative in silico analysis highlights compounds derived from Piper betle L. leaves as a promising natural source of ACE-inhibitory scaffolds and provides a rational framework for subsequent experimental validation and lead optimization in antihypertensive drug discovery.

This study aims to analyze the implementation of revitalizing the Betawi language at the elementary school (SD) and junior high school (SMP) levels in Jakarta through the integration of local culture in educational activities. The study employs a qualitative approach with a descriptive method to describe the practices of using the Betawi language in school learning contexts. Data were collected through classroom observations, interviews with teachers and students, and analysis of learning documents and school cultural activities. The results show that the policy of revitalization of the Betawi language is more effective when integrated into project-based learning, school cultural activities, and creative activities that incorporate elements of Betawi culture, such as art performances, role-playing, and daily communication practices. This approach has proven capable of increasing students’ interest, participation, and awareness of the Betawi language as part of their local cultural identity. However, its implementation of the revitalization program still faces several challenges, including the absence of a specific curriculum, limited teaching materials, lack of teacher training, and the influence of popular and global languages in students’ daily lives. Therefore, it is necessary to develop a strategy to include a structured curriculum or local content program, provide relevant teaching materials, improve teacher capacity, and utilize digital technology and social media as learning media. Sustainable policy support and collaboration among schools, government, and communities are essential factors in strengthening the revitalization of the Betawi language and maintaining the sustainability of local language as part of Jakarta’s cultural identity.
