This study aims to analyze the development of regional financial performance and its effect on economic growth in Jambi Province during the 2019–2023 period. Regional financial performance is measured using the Regional Financial Independence Ratio and the Fiscal Decentralization Degree (FDD), while economic growth is proxied by Gross Regional Domestic Product (GRDP). This research employs a quantitative approach using secondary data obtained from the Central Statistics Agency (BPS), the Directorate General of Fiscal Balance (DJPK), and regional government financial reports covering 11 regencies/cities in Jambi Province. The analytical method applied is panel data regression using the Random Effect Model (REM). The results indicate that both regional financial performance and economic growth in Jambi Province experienced fluctuations throughout the study period. Partially, the Fiscal Decentralization Degree (FDD) has a positive and significant effect on GRDP, with a probability value of 0.0138. In contrast, the Regional Financial Independence Ratio does not have a significant effect on GRDP, as indicated by a probability value of 0.8843. Simultaneously, FDD and the Regional Financial Independence Ratio significantly affect GRDP, with an F-statistic probability value of 0.0390. The coefficient of determination (R²) is 0.1173, indicating that 11.73% of GRDP variation can be explained by the two variables, while the remaining 88.27% is influenced by other factors outside the research model. This study concludes that strengthening regional fiscal capacity through the optimization of local own-source revenue and fiscal decentralization policies is essential for promoting sustainable economic growth in Jambi Province.

This review article evaluates the physical characteristics and stability of Oil in Water (O/W) and Water in Oil (W/O) creams through a comparative literature study published between 2021 and 2026. The evaluation focuses on important parameters, including viscosity, spreadability, adhesion, pH, and accelerated stability testing. The findings reveal that O/W creams generally have lower viscosity and greater spreadability, making them more suitable for daily cosmetic and therapeutic applications due to their lighter texture and better aesthetic acceptance. In contrast, W/O creams demonstrate higher physical stability, stronger adhesion, and superior occlusive properties, which are beneficial for protecting sensitive active ingredients and maintaining skin hydration over longer periods. The differences in performance are strongly influenced by the optimization of emulsifier Hydrophilic-Lipophilic Balance (HLB) values and the ratio between oil and water phases. Both cream types show good biocompatibility with skin pH ranging from 4.5 to 6.5, indicating their safety and effectiveness for topical pharmaceutical and cosmetic formulations.

Effervescent granules are a pharmaceutical dosage form that offer advantages in terms of ease of use, improved palatability, and rapid solubility in water. This study aimed to formulate and evaluate the physical properties of vitamin C Effervescent granules using the dry granulation method. The main materials used included ascorbic acid as the active substance, citric acid and tartaric acid as acid sources, and sodium bicarbonate as the base source. Evaluation was carried out on organoleptic properties, flow properties, pH, angle of repose, moisture content, density, compressibility index, and dispersion time. The results showed that the granules met the requirements for organoleptic properties, pH (4–5), angle of repose (38.41°), compressibility index (12.3%), and dissolution time (49.62 seconds). However, the flow property (29.11 seconds) and moisture content (6.47%) did not meet the established standards. These findings indicate that the formulated granules met most of the evaluation parameters but still require optimization, particularly in the drying process and flow properties, to obtain a more stable and high-quality dosage form.

This study aims to analyze the conformity between the Tax Object Sales Value (NJOP) and land market value and its implications for optimizing Local Own-Source Revenue (PAD) from the Rural and Urban Land and Building Tax (PBB-P2) sector in Oebobo District, Kupang City. The research employed a quantitative approach with descriptive and comparative methods. Data were obtained from the Kupang City Regional Revenue Agency (Bapenda), the Directorate General of Fiscal Balance (DJPK), land market surveys, and property transaction data. The analysis was conducted by comparing NJOP values with actual land market prices using conformity ratio analysis. The results indicate that the conformity level between NJOP and land market value in Oebobo District remains low, ranging from 7.97% to 12.06%. Oetete Village recorded the highest conformity level at 12.06%, while Kayu Putih Village showed the lowest at 7.97%. These findings demonstrate that the NJOP determined by the local government has not yet reflected the actual market value of land. Although the realization of PBB-P2 revenue during 2021–2025 showed relatively effective performance, the low NJOP has caused the tax base to remain below the actual economic value of land, thereby limiting the optimization of PAD. Therefore, periodic and market-based NJOP adjustments are necessary to improve fiscal fairness, strengthen the regional tax base, and increase local revenue from the PBB-P2 sector sustainably.

Although cryptographic security is often the main concern in e-voting system development, practical implementation failures are frequently associated with poor user interfaces that increase cognitive load and voting errors. This study evaluates the effectiveness of User-Centered Design (UCD) interventions in improving usability and voter confidence in an e-voting system. A one-group pretest-posttest design was applied to 36 respondents representing novice voters. Usability was measured using the System Usability Scale (SUS) before and after the interface redesign. The intervention focused on visual hierarchy, navigation consistency, status visibility, and error prevention. The results show a statistically significant improvement, with the mean SUS score increasing from 69.10 in the marginal category to 95.76 in the excellent category. The paired sample t-test produced t(35) = -7.3441 with p < 0.0001, while Cohen's d reached 1.2130, indicating a large practical effect. The standard deviation also decreased from 21.98 to 3.09, demonstrating a more consistent user experience. These findings indicate that interface optimization is essential for strengthening accessibility, voting accuracy, and user trust in digital democracy systems.

The findings reveal that the successful implementation of PjBL is influenced by competency-based planning, effective organization of learning resources, authentic project implementation, and continuous evaluation through authentic assessment. Institutional readiness, teacher competence, digital technology, and industrial partnerships also contribute significantly to the sustainability of PjBL implementation in vocational education.

The implementation of active learning models such as Problem-Based Learning (PBL) and Project-Based Learning (PjBL) at the junior high school level is often constrained by the complexity of instructional time management. This study aims to examine the role of the principal’s instructional leadership in addressing time management dilemmas in the implementation of active learning at SMP Negeri 6 Panyabungan. A qualitative approach with a descriptive method was employed in this study. Data were collected through non-participant observation and in-depth interviews with key informants, namely the school principal and an Islamic Religious Education (PAI) teacher selected as representatives of field conditions. The findings reveal three main results. First, teachers’ time management constraints are caused by weak control of learning activity transitions, noisy classroom conditions during group division, and low initial student learning readiness. Second, the principal implemented several concrete interventions, including the adoption of block scheduling, clinical supervision focused on classroom management, and the optimization of the Subject Teacher Forum (MGMP) or school learning community. Third, these interventions improved teachers’ instructional efficiency, strengthened classroom activity control, and created a more structured active learning process. However, sustainability challenges remain, particularly resistance from senior teachers who tend to prefer conventional teaching methods. This study concludes that adaptive and solution-oriented instructional leadership is a key factor in addressing the complexity of time management constraints in active learning implementation.

The adoption of holocratic leadership systems has become a crucial strategy for startups navigating market volatility, which demands organizational agility through the elimination of traditional hierarchies. This study aims to analyze the transformation of the Human Resource (HR) department's role within holocratic systems and its impact on HR efficiency in startup environments. Employing an integrative literature review approach, this research synthesizes various findings from reputable global and national journals published within the last five years to map the shifts in managerial functions. The results indicate that in structures devoid of conventional managers, the HR role transforms from a controlling authority into a system architect and governance facilitator that maintains compliance with the organizational constitution. HR efficiency is achieved through clear authority distribution within dynamic roles, transparent peer-to-peer feedback mechanisms, and the removal of slow bureaucratic coordination costs. The contribution of this research lies in the formulation of the "HR-as-a-Platform" conceptual model, which shifts the focus of management practices from personal supervision to systemic infrastructure optimization. The practical implications provide a guide for startup founders to re-engineer HR functions to support individual autonomy without sacrificing operational stability. This study confirms that the success of non-hierarchical organizations relies heavily on the integration of radical autonomy and robust digital protocols facilitated by the newly defined HR function.

This research is motivated by the phenomenon of Izhar Majid’s election, as he successfully maintained his position as a legislative member in Jambi Province and achieved a significant victory in his constituency despite intense political competition. His success is notable because he does not come from a political family, lacks elite family connections, and was still able to maintain his voter base after switching political parties. This condition raises questions about how he utilized political capital to gain public support. The study aims to analyze the forms, strategies, and utilization of political capital in winning political contests. Using political capital theory, this descriptive qualitative research collected primary data through interviews and secondary data from documentation, literature, and official election results. The findings show that his success was driven by the optimization of integrated political capital. Social capital was built through strong networks with community leaders and voter groups. Symbolic capital emerged from his positive image and reputation. Economic capital supported structured campaign activities. Combined with direct public engagement and targeted communication media, these factors significantly increased his visibility and electability.

The presence of BUMDes is an important factor in improving the economy and community independence, such as through the village savings and loan program. However, the lack of socialization and inaccurate targeting of program recipients are problems that have implications for BUMDes capital turnover. This study aims to explain the optimization of the savings and loan program in BUMDes in realizing the economic independence of the community of Kalimanah Kulon Village, Kalimanah District, Purbalingga Regency. This study uses a qualitative case-study approach. Data were obtained through interviews, observations, and document analysis.

This study aims to describe the level of service optimization in Financial Institution Pension Funds (DPLK) through the management of periodic pension benefit payments, additional benefits, and voluntary contributions using a descriptive-analytical approach. The data were derived from reports of 24 DPLK administrators collected in April 2026. The findings indicate that service optimization is largely determined by the effectiveness of managing periodic pension payments, other pension benefits, and contributions beyond the core program. This issue becomes crucial when viewed from DPLK performance trends over the past five years (2021–2025), where collected funds—comprising contributions and investment returns—were consistently lower than pension benefit payments, with an average ratio of 63%. This imbalance highlights sustainability concerns. The study identifies significant untapped potential, including Rp5.79 trillion annually (36% of total pension benefits) in periodic payments not yet optimized, Rp2.4 trillion for other benefit programs over 10 years, Rp1 trillion for religious-related funds, and Rp1.2 trillion in voluntary contributions from existing participants. To address these gaps, DPLK institutions need to strengthen regular and personalized communication beyond transactional interactions, ensuring participants are more engaged. Integrated services that emphasize transparent benefits, ease of contribution, continuous financial education, and digital accessibility are essential. Ultimately, optimizing DPLK services requires not only system and product improvements but also attention to participant behavior and service quality to enhance retirement well-being.
