Abstract

Diabetes is a chronic metabolic disease characterized by hyperglycemia, with type 2 diabetes mellitus (T2DM) being the most prevalent worldwide. This descriptive quantitative study aimed to identify potential drug–drug interactions (pDDIs) in T2DM outpatients. A total of 100 medical records from the outpatient department in 2024 were selected using accidental sampling. Most patients were female (57%) and aged 46–65 years (72%). Prescriptions commonly contained fewer than seven drugs (87%), with metformin being the most frequently prescribed antidiabetic (30.9%) and sulfonylureas the most common drug class (34.6%). Drug interactions were identified in 76% of prescriptions, predominantly of moderate severity (63.2%) and pharmacokinetic mechanism (50.6%)

Abstract

This study examines the role of AI usefulness in shaping purchase intention within AI-driven personalised marketing. A quantitative explanatory design was employed using an online survey of 400 e-commerce consumers in DKJ Jakarta collected June 2025 to August 2025. Data were analysed using SEM-PLS to test direct and mediating effects among AI usefulness, consumer trust, perceived risk, consumer knowledge, and purchase intention. The findings reveal that AI usefulness significantly increases consumer trust and knowledge while reducing perceived risk, but does not directly influence purchase intention. Purchase intention is driven by trust and knowledge, with significant indirect effects identified. The study highlights the importance of trust-building and knowledge enhancement in maximising AI-based marketing effectiveness

Abstract

Background: Processed food refers to food products that have undergone preparation, with or without additional ingredients. Various types of ready-to-eat processed foods are sold at food stalls around Universitas Indonesia Station and are widely consumed by the public. Escherichia coli, a common gastrointestinal bacterium, serves as an indicator of microbial contamination according to the Regulation of the Minister of Health of the Republic of Indonesia No. 2 of 2023. Methods: A Total Plate Count (TPC) was conducted using selective MacConkey Agar. Five popular ready-to-eat processed food samples were collected from three different food stalls: capcay and omelette from Food Stall A, soy sauce–seasoned chicken and Mustofa potatoes from Food Stall B, and stir-fried water spinach from Food Stall C. Results: TPC analysis revealed no E. coli growth in any of the tested samples. Specifically, capcay and omelette from Food Stall A, soy sauce–seasoned chicken and Mustofa potatoes from Food Stall B, and stir-fried water spinach from Food Stall C showed no microbial contamination. Conclusion: All examined ready-to-eat processed food samples met the microbiological standards specified by the Indonesian Ministry of Health

Abstract

Public participation in reporting road conditions is increasing through digital-based road damage complaint applications. However, handling road damage complaints is still hampered by inaccurate data, inadequate system monitoring of repairs and quality, manual management of costs and repair history, and a lack of data integration. This situation necessitates repair cost analysis for each repair, documentation of damage history and repair methods, and WebGIS-based spatial mapping of repairs to ensure data is documented, tracked, and analyzed more systematically for monitoring and evaluating road maintenance within a single system. This research is important to conduct because it can contribute to the development of a WebGIS-based road maintenance monitoring and evaluation system integrated with road damage complaints. The research not only analyzes the condition of road damage and repairs, but also analyzes the economic feasibility of developing WebGIS using the ROI and BCR methods. The results of the research are expected to help road management agencies in improving the effectiveness and efficiency of road maintenance through the use of WebGIS technology. The feasibility analysis of WebGIS investment using the ROI method yielded a positive ROI of 76.90%, making it financially viable. The calculated BCR value of 1.68 indicates that the benefits of WebGIS development are financially viable (BCR > 1)

Abstract

This study examines the effects of exchange rates, GDP, commodity prices, and inflation on Indonesia’s CPO export volume. A quantitative approach was employed using secondary time-series data from January 2018 to December 2024, comprising 84 observations. Data were analyzed using PLS-SEM with SmartPLS 4.1.1. The results indicate that exchange rates and GDP positively and significantly affect CPO export volume. Conversely, commodity prices exert a negative and significant effect, whereas inflation has no direct significant influence. Furthermore, inflation strengthens the exchange rate–export relationship but weakens the effects of GDP and commodity prices on Indonesia’s CPO exports

Abstract

Pakcoy (Brassica rapa L.) is an economically valuable horticultural crop whose growth can be improved with organic fertilizers. This study examined the effects of cow manure and liquid organic fertilizer from rabbit urine on pakcoy growth and yield. The research was using a factorial randomized block design. Cow manure was applied at 0, 1, 2, and 3 kg per plot, while rabbit urine fertilizer was applied at 40, 50, and 60 ml per plot. Observed variables were plant height, leaf number, and plant weight per plot. Results showed that cow manure significantly affected all variables. The 2 kg per plot treatment gave the best results, while rabbit urine fertilizer and interaction effects were not significant

Abstract

This study aims to examine the effect of market attractiveness, digital leadership, and strategic business on business performance. Research data was collected through questionnaires to 55 telematics industry companies in the city of Bandung. The data is then processed using Partial Least Square (PLS). Research found that market attractiveness and digital leadership influence strategic business, where digital leadership has the dominant influence. Digital leadership can encourage business performance, but market attractiveness is not able to directly increase business performance. Strategic business can increase business performance. Market attractiveness and digital leadership can improve business performance through strategic business. These findings provide managerial implications for company management in the telematics industry to prioritize the implementation of strategic business to improve business performance

Abstract

Manual monitoring of hotel customer reviews on Google Maps is increasingly inefficient due to growing review volumes, particularly in detecting negative sentiment. This study proposes a web-based sentiment monitoring system integrated with Naive Bayes and Support Vector Machine (SVM) for automated sentiment classification of Google Maps reviews at Aveta Hotel Malioboro. A dataset of 2,449 historical reviews was collected via DOM scraping and processed through text preprocessing and TF-IDF feature extraction. SVM with minority-class oversampling achieved the highest performance: accuracy 0.9540, precision 0.9514, recall 0.9540, and F1 Score 0.9522. The implemented system retrieves reviews periodically via SerpAPI, classifies sentiment automatically, and delivers real-time Telegram notifications, enabling structured and data-driven hotel review monitoring

Abstract

In tropical countries, including, Indonesia, venomous snake bites remain a significant public health problem. Through the activation of proinflammatory cytokines, the complement system, and oxidative stress, envenomation can cause tissue damage and systemic complications. Antivenom is the primary method for neutralizing toxins, but its heterologous immunoglobulin content can trigger immune reactions. This study examines how snake venom and antivenom affect the immune system. A total of 19 articles from a literature review published between 2020 and 2026 were evaluated using narrative synthesis. Data were collected from SINTA-indexed national journals, PubMed, ScienceDirect, and Google Scholar. The results show that snake venom can cause local and systemic inflammation, while antivenom can cause hypersensitivity and even serum sickness. To improve the safety and effectiveness of therapy, antivenom remains the primary choice. However, monitoring for immunological risks is necessary
