Optimising the SIMKAH Policy to Accelerate Marriage Administration A CIPP Model Evaluation and Findings on Infrastructure Improvements at KUA Seberang Ulu II, Palembang City

/in /by

Public services are increasingly expected to deliver faster, more accurate, and traceable administrative processes, particularly for marriage registration, where data validity has long-term legal consequences. In Indonesia, SIMKAH is designed to digitise and integrate marriage administration to enhance service efficiency and data consistency at KUA offices. However, the presence of SIMKAH does not automatically guarantee faster service, as the quality of implementation relies on local readiness and operational stability. At KUA Seberang Ulu II, several practical constraints may hinder administration, especially those related to infrastructure and workflow execution. This study proposes policy optimisation by aligning SIMKAH objectives with daily operational procedures to ensure that acceleration goals are clearly reflected in real service workflows. It highlights the importance of strengthening input readiness through adequate human resources, needs-based budgeting, and notably improved supporting infrastructure such as dedicated hardware. The optimisation also focuses on process reinforcement by stabilising internet connectivity, preparing operational procedures to manage system interruptions, and reducing rework caused by identity data mismatches. Furthermore, user support and guidance are emphasised to improve document readiness and minimise delays during verification and data entry. The study evaluates SIMKAH implementation using the CIPP framework (Context–Input–Process–Product) through a qualitative descriptive approach based on interviews, observation, and documentation. Findings are mapped onto the CIPP dimensions to identify key gaps, with the most significant areas for improvement related to process and infrastructure. This research provides a structured, decision-oriented assessment of a digital public service policy, demonstrating how the CIPP framework can reveal implementation bottlenecks beyond system availability. Practically, it offers actionable recommendations for infrastructure development and workflow standardisation to support a more consistent acceleration of marriage administration at KUA Seberang Ulu II, Palembang City.

Solid Waste Management and Material Recovery Facility Planning in Leh-Ladakh, Western Himalaya

/in /by

Rapid urbanization, tourism growth, and changing consumption patterns have significantly increased solid waste generation in Leh Ladakh, a high-altitude cold desert region of India. This study examines the existing status of waste generation, segregation, and disposal practices in Leh, the largest town in Ladakh, and assesses the feasibility of establishing a Material Recovery Facility (MRF). Field-based inventory, secondary datasets, and the Solid Waste Management (SWM) Manual 2016 were used to estimate waste quantities and design MRF requirements. Results indicate that Leh generates approximately 13.02 tonnes per day (TPD) of solid waste, with 80% comprising dry waste and 20% wet waste. The dry fraction includes paper and cardboard (30%), tetra packs (20%), textiles (17%), PET (8%), and multilayer plastics (7%). Currently, segregation and limited recycling occur at a municipal facility powered by solar energy. However, the absence of a formal MRF, shortage of equipment, and lack of skilled manpower remain key challenges. The study proposes a manual MRF model suitable for <15 TPD, with an estimated operational cost of Rupees 3.06 lakh per annum. Establishing such a facility would improve recycling efficiency, reduce environmental risks, and promote sustainable waste management in this ecologically fragile Himalayan region.

The Effectiveness of Lime Juice (Citrus aurantifolia) in Preventing Calcium Oxalate Crystal Formation: An In Vitro Model

/in /by

Background: Calcium oxalate (CaOx) stones are the most prevalent type of urolithiasis and are associated with high recurrence rates. Preventive approaches targeting early crystallization stages, particularly nucleation and aggregation, are therefore crucial. Citrate is a recognized inhibitor of CaOx crystallization; however, pharmacological citrate therapy may face limitations in long-term use. Lime juice (Citrus aurantifolia), a natural source of citrate, may serve as an alternative preventive agent.

Objective: To evaluate the inhibitory effect of lime juice (Citrus aurantifolia) on calcium oxalate crystal formation in vitro.

Methods: A true experimental study with a post-test only control group design was conducted using a synthetic urine model. Five groups were assessed: negative control, positive control (potassium citrate 0.6%), and lime juice at concentrations of 2.5%, 5%, and 10% (v/v). Crystallization was monitored turbidimetrically at 620 nm for 60 minutes. Nucleation slope (SN), aggregation slope (SA), time to maximum absorbance (Tmax), and inhibition percentages were analyzed using one-way ANOVA and Tukey’s HSD test.

Results: All lime juice concentrations significantly reduced aggregation and prolonged Tmax compared with the negative control. The 5% concentration showed the strongest nucleation inhibition among natural treatments, while 2.5% demonstrated the highest aggregation inhibition.

Conclusion: Lime juice effectively inhibits CaOx crystallization in vitro and shows potential as a natural, accessible preventive strategy.

Application of 18S rRNA Gene-Based and β-Giardin Molecular Markers for Early Detection of Giardia duodenalis Infection

/in /by

Giardiasis and other intestinal parasite infections are still prevalent and a public health concern, especially in areas with inadequate sanitation and hygiene. Giardia duodenalis infections can cause mild to severe symptoms, such as chronic diarrhea, malabsorption, and growth impairment in children, so early detection is essential. The commonly used fecal microscopy test has a low sensitivity, particularly for infections with low parasite loads or in the absence of symptoms. The development of molecular diagnostic methods based on the polymerase chain reaction (PCR) provides a more accurate and sensitive alternative by using specific genetic markers. This review of the literature looks at the roles of the 18S rRNA and β-giardin genes as molecular markers for the early detection of Giardia duodenalis infection. The review’s conclusions indicate that the 18S rRNA gene’s high sensitivity and robust sequence stability make it suitable for initial screening and epidemiological surveillance. In contrast, the β-giardin gene is useful for genotype analysis and diagnostic confirmation because of its higher specificity. The combination of these two genes may be the most effective diagnostic strategy to improve the accuracy of early Giardiasis detection in both clinical and epidemiological settings.

Thermodynamic and Transport Excess Properties of Ethyl Benzoate + 2-Methyl-2-Propanol Binary Mixtures At (303.15–318.15) K

/in /by

Excess thermodynamic and transport properties of binary liquid mixtures composed of ethyl benzoate (X₁) and 2-methyl-2-propanol (X₂) were measured over the entire composition range at four temperatures: 303.15, 308.15, 313.15, and 318.15 K at atmospheric pressure. Experimental properties including excess molar volume (Vᵉ), excess isentropic compressibility (Δβₐd), viscosity deviations (Δη), excess free length (Lᵉ), excess surface tension (πᵉ), excess acoustic impedance (Zᵉ), excess enthalpy (Hᵉ), excess Gibbs free energy (Gᵉ), and ultrasonic velocity (U) were systematically evaluated. The results indicate consistently negative Vᵉ, Δβₐd, and Δη values across all compositions and temperatures, with magnitudes that reach minima near equimolar composition, suggesting strong specific interactions between unlike molecules, especially dipole–dipole and hydrogen bonding effects. Temperature rise generally reduces the magnitude of excess properties, indicative of diminished molecular interactions and structural organization at elevated thermal energy. All excess functions were correlated using the Redlich–Kister polynomial equation, demonstrating excellent fit quality and enabling estimation of binary interaction parameters. The observed trends in excess enthalpy and Gibbs free energy reveal significant non-ideal behavior, likely due to disruption of self-association in 2-methyl-2-propanol clusters upon mixing with aromatic ester molecules. Comparisons with literature reveal qualitative agreement with related binary systems involving esters and alcohols, confirming the reliability of the measured data. Overall, this study provides comprehensive thermodynamic insights into molecular interactions in ester-alcohol mixtures, supporting improved modeling of solution behavior relevant to industrial and formulation applications.

Association Between Screen Time Duration and the Incidence of Dry Eye Syndrome Among Educational Staff at Nusa Cendana University

/in /by

Background: The rising intensity of digital device use in daily activities contributes to prolonged screen time, which may disrupt tear film stability through reduced blink frequency and increased evaporation. Educational staff represent a high-risk group due to the sedentary nature of their work and prolonged screen exposure in air-conditioned environments that can exacerbate ocular surface disturbances.

Objective: To assess the association between screen time duration and the occurrence of Dry Eye Syndrome (DES) among educational staff at the University of Nusa Cendana.

Methods: This analytical observational study with a cross-sectional design was conducted from September to October 2025. A total of 54 respondents were selected using cluster random sampling. Screen time duration was measured using the Screen Time Questionnaire (STQ), while DES symptoms were evaluated using the Ocular Surface Disease Index (OSDI). Correlation analysis was performed using the Spearman Rank test.

Results: Most respondents reported a moderate level of screen time exposure (46.3%) and normal ocular status based on OSDI (50%). However, 24.1% of respondents were identified as having severe DES. Statistical analysis demonstrated a significant positive correlation of moderate strength between screen time duration and DES severity (p = 0.003; r = 0.400). Respondents with high and very high screen time exposure tended to exhibit more severe symptomatic manifestations.

Conclusion: Screen time duration is significantly associated with the severity of Dry Eye Syndrome among educational staff. Interventions such as scheduled visual breaks and ergonomic adjustments in the workplace are recommended to reduce the risk of ocular surface disorders.

The results indicated that the developed media was highly valid, with validation scores of 98% from media experts, 96% from language experts, and 95% from content experts. The effectiveness test showed a significant improvement in students’ reading comprehension skills, as reflected by N-Gain scores of 0.78 in the small-group trial and 0.77 in the large-group trial, both categorized as high. Therefore, the Lift-The-Flap-Book based on deep learning principles is valid, effective, and feasible for enhancing elementary students’ reading comprehension skills.

Risk of Type 2 Diabetes Mellitus with Neurological Complications: Review

/in /by

Background: Type 2 Diabetes Mellitus (T2DM) is one of the chronic metabolic diseases with a prevalence that continues to increase globally. This disorder not only affects glucose metabolism but also causes multisystem complications, including neurological complications such as peripheral neuropathy, autonomic dysfunction, and cognitive impairment.

Objective: This study aims to comprehensively analyze the latest empirical evidence regarding the relationship between type 2 diabetes (DMT2) and the risk of neurological complications.

Methods: This study uses a Systematic Literature Review (SLR) approach following the PRISMA method.

Results: The findings indicate that DMT2 patients have a higher risk of developing neurological complications, both peripheral and central. Certain antidiabetic medications, such as SGLT2 inhibitors and GLP-1 receptor agonists, show protective effects in reducing the risk of dementia and neurodegeneration. Additionally, factors such as disease duration, age at diagnosis, and genetic status (e.g., APOE ε4) also contribute to variations in risk levels. Non-pharmacological interventions, such as regular physical activity and good metabolic control, have also been shown to improve cognitive function and slow the progression of neuropathy.

Conclusion: Based on the study results, DMT2 significantly increases the risk of neurological complications through mechanisms of inflammation, oxidative stress, and insulin resistance that affect nerve tissues. Pharmacological interventions with modern agents such as GLP-1 agonists and SGLT2 inhibitors show protective prospects against neurodegeneration.

The Effectiveness of Macroprudential Policy in Developing Countries: A Systematic Literature Review of Its Impact on the Stability and Strategic Performance of the Banking Sector

/in /by

This study aims to evaluate the effectiveness of macroprudential policies in enhancing stability and strategic performance in the banking sectors of developing countries through a Systematic Literature Review (SLR) approach. The primary focus is to assess the extent to which various policy instruments—such as the Loan-to-Value (LTV) ratio, Countercyclical Capital Buffer (CCyB), and Reserve Requirements (RR)—contribute to mitigating systemic risk, reducing credit procyclicality, and influencing bank profitability and efficiency. Employing the PRISMA framework, the study analyzes 87 empirical studies sourced from Scopus, Web of Science, ProQuest, and EBSCOhost, published between 2010 and 2024. Thematic synthesis and bibliometric analysis using VOSviewer were conducted to synthesize the findings. The results indicate that macroprudential policies are generally effective in strengthening banking sector resilience to external shocks and curbing systemic risk accumulation, although their efficacy is highly contingent upon institutional capacity and policy coordination within individual countries. Furthermore, a trade-off emerges between systemic stability and operational efficiency: stringent macroprudential measures tend to dampen short-term profitability while enhancing long-term resilience. This research contributes to the literature on financial management and strategic banking by comprehensively integrating macroprudential and microprudential dimensions and offering policy recommendations tailored to the institutional and economic contexts of developing economies.
