Tropical fungal skin infections, including Tinea corporis, Tinea versicolor, Tinea pedis, and Tinea nigra, are common health problems in tropical countries such as Indonesia. Although not life-threatening, these diseases can cause discomfort, reduce self-confidence, and interfere with daily activities. Conventional diagnostic methods still rely on subjective visual observation, which is often inaccurate—especially in regions with limited infrastructure and scarce access to specialists. Moreover, existing studies rarely provide a comparative evaluation of deep learning architectures for tropical fungal infections using small and diverse datasets. Therefore, this study aims to address these challenges by conducting a systematic comparative evaluation of three pre-trained models—MobileNetV3, EfficientNet-B2, and SE-ResNet101—to determine the most accurate and computationally efficient architecture for multi-class classification of tropical fungal skin diseases. In this study, a dataset of 660 clinical skin images sourced from the Kaggle repository was used, covering four tropical fungal infection classes. The dataset consisted of 165 images per class, which were divided into training, validation, and testing subsets. Experimental results demonstrated that MobileNetV3 achieved the best performance, with a validation accuracy of 95.08%, a test accuracy of 97.34%, and the shortest training time of 15 minutes, compared to EfficientNet-B2 (16 minutes) and SE-ResNet101 (22 minutes). The main contribution of this study is to provide a systematic comparative evaluation of deep learning models for the classification of tropical fungal skin infections, while recommending MobileNetV3 as the most suitable model for practical implementation of automated image-based diagnosis in primary healthcare services with limited resources.

Media sosial telah menjadi bagian penting dalam kehidupan masyarakat, namun peningkatan penggunaannya sering dikaitkan dengan dampak negatif terhadap kesehatan mental seperti stres, adiksi, FoMo, dan insomnia. Upaya prediksi risiko penggunaan media sosial dapat membantu menjaga kesehatan mental dengan memanfaatkan teknik data mining. Penelitian ini menggunakan metodologi CRISP-DM sebagai kerangka utama serta Exploratory Data Analysis (EDA) untuk mengidentifikasi tren dan anomali yang mendukung proses pemodelan. Beberapa algoritma supervised learning seperti C4.5, k-NN, dan Naïve Bayes diterapkan untuk memprediksi dampak negatif penggunaan media sosial terhadap kesehatan mental. Hasil eksperimen menunjukkan bahwa Naïve Bayes memberikan kinerja terbaik dengan akurasi tertinggi sebesar 92,5%, melampaui C4.5 dan k-NN. Integrasi EDA dan CRISP-DM terbukti menghasilkan model prediksi yang akurat, meskipun penerapan EDA memerlukan waktu tambahan dalam analisis. CRISP-DM berperan penting dalam menyediakan kerangka kerja yang sistematis sehingga membantu peneliti bekerja lebih terstruktur dan mengurangi risiko kesalahan. Selain itu, temuan memperlihatkan bahwa semakin lama seseorang menggunakan media sosial, semakin besar dampak negatif yang dialami, terutama bagi mereka yang menghabiskan waktu lebih dari lima jam per hari. Secara keseluruhan, hasil penelitian ini memberikan kontribusi terhadap pengembangan model prediksi berbasis data mining dan dapat menjadi landasan bagi upaya pencegahan gangguan kesehatan mental akibat penggunaan media sosial. Abstract Social media has become an integral part of modern life, enabling users to express feelings and opinions. However, its increasing use has been linked to negative impacts on mental health, such as stress, addiction, FoMo, and insomnia. Predicting the risks associated with social media use can help maintain mental well-being, and this can be achieved through data mining techniques. This study applies the CRISP-DM methodology as the main framework, complemented by Exploratory Data Analysis (EDA) to identify trends and anomalies that support the modeling process. Several supervised learning algorithms, including C4.5, k-NN, and Naïve Bayes, were employed to predict the negative impact of social media use on mental health. Experimental results show that Naïve Bayes achieved the best performance with the highest accuracy of 92.5%, outperforming both C4.5 and k-NN. The integration of EDA and CRISP-DM proved effective in producing accurate predictive models, although EDA required additional time for data analysis. CRISP-DM played a crucial role in providing a systematic framework, enabling researchers to work more structurally and minimizing the risk of errors. Furthermore, findings indicate that the longer individuals spend on social media, the greater the negative impact they experience, particularly among those using it for more than five hours per day. Overall, this study contributes to the development of predictive models based on data mining and provides insights that may support preventive efforts against mental health issues caused by excessive social media use.

<jats:p>This study analyzes the effect of transparent digital nudging on digital consumer loyalty through perceived autonomy and consumer trust on digital platforms in Indonesia. An explanatory quantitative study was conducted on 400 digital consumers using SEM-PLS. The analysis results show that transparent digital nudging has a significant effect on perceived autonomy with a large effect size (f2 0.375), and perceived autonomy subsequently strengthens consumer trust with a small effect size (f2 0.100). Consumer trust was found to be the strongest predictor of loyalty with a large effect size (f2 0.742), while nudging and autonomy do not directly affect loyalty. Serial mediation testing was proven significant with a moderate mediation effect (v 0.092). These results confirm that long-term digital consumer loyalty is formed through trust-based relational mechanisms, not through instant digital design interventions. This study expands the relationship marketing literature by positioning digital choice architecture design as a consumer relationship management practice.</jats:p>

<jats:p>This study examines factors influencing library visit frequency in the digital era, where declining reading interest and changing user behavior pose significant challenges. It analyzes the relationship between on-site reading, book circulation by classification, and visit intensity, while identifying the most influential factors driving visits. A quantitative correlational design with a non-parametric approach was applied using secondary data from the Inlislite system of the Metro City Library and Archives Service, covering January 2023 to August 2024. Spearman correlation was employed to assess the strength and direction of relationships among variables. The findings reveal that on-site reading activity has a very strong positive correlation with visit frequency. Collections in literature, social sciences, and religion show moderate correlations, whereas pure and applied sciences exhibit no significant relationship. These results highlight the strategic importance of reading spaces and popular collections in fostering user engagement. This study provides practical implications for library management, including optimizing reading areas, aligning collections with user interests, and promoting underutilized materials. It contributes to the literature by integrating reading, circulation, and visitation dimensions into a unified data-driven framework to support adaptive and user-centered library services.</jats:p>

Cash waqf is an Islamic financial instrument that has the potential to fund social projects, particularly in addressing inequality and poverty issues. However, the traditional management still faces challenges, such as limited transparency and public participation reach. Digitization through fintech with crowdfunding modeling was considered capable of increasing donor participation while improving the effectiveness of management and distribution. This research aimed to provide a comprehensive overview of the development of cash waqf, mapping the trends, identifying the main factors influencing its development, and exploring gaps, particularly in the context of integration with crowdfunding models. The process led to the adoption of performance analysis and science mapping methods. Performance analysis was conducted descriptively to measure productivity and impact through bibliometric indicators. Science mapping was used to review the research landscape by analyzing the relationships and structures of topics, authors, and relevant institutions. It was also used to identify collaboration patterns, thematic focuses, including under-researched areas, and integration with crowdfunding platforms. The results showed that regulatory aspects, contemporary digital technology innovations, and the role of Islamic financial institutions were factors influencing the development of cash waqf research. Topic modeling analysis proved that the exploration on the integration of cash waqf and crowdfunding was limited. This led to a gap in research on the governance of digital waqf platforms, as well as strategies to enhance public participation through technology. The research provided a map that served as a reference, including used by regulators and platform developers in designing policies and innovations for digital waqf products.

Online reviews are an essential aspect of online shopping for both customers and retailers. However, many reviews found on the Internet lack in quality, informativeness or helpfulness. In many cases, they lead the customers towards positive or negative opinions without providing any concrete details (e.g., very poor product, I would not recommend it). In this work, we propose a novel unsupervised method for quantifying helpfulness leveraging the availability of a corpus of reviews. In particular, our method exploits three characteristics of the reviews, viz., relevance, emotional intensity and specificity, towards quantifying helpfulness. We perform three rankings (one for each feature above), which are then combined to obtain a final helpfulness ranking. For the purpose of empirically evaluating our method, we use review of four product categories from Amazon review 1 . The experimental evaluation demonstrates the effectiveness of our method in comparison to a recent and state-of-the-art baseline.

The digital technology has turned out to be a revolution to gender equality and the socioeconomic empowerment of women due to its fast development. This paper discusses the digital innovation process as a radical platform in ensuring gender equity and inclusive development. Technology has given women a platform where they are able to speak out, become financially stable and be in frontline to fill up the geographical and social barriers. The case studies examined in the paper include the women-led start-ups, the digital literacy programs, and the e-governance programs that can increase inclusivity and reduce structural disadvantages. Finally, the paper provides the argument that innovation can trigger holistic development of women and transform socioeconomic systems, guided by inclusiveness and equity. The gender and technology intersect therefore is not only a place of usage but a place to change where women are not only consumers but creators of the online future.

Research on fake reviews detection and review helpfulness prediction is prevalent, yet most studies tend to focus solely on either fake reviews detection or review helpfulness prediction, considering them separate research tasks.In contrast to this prevailing pattern, we address both challenges concurrently by employing a multi-task learning approach.We posit that undertaking these tasks simultaneously can enhance the performance of each task through shared information among features.We utilize pre-trained RoBERTa embeddings with a document-level data representation.This is coupled with an array of deep learning and neural network models, including Bi-LSTM, LSTM, GRU, and CNN.Additionally, we employ ensemble learning techniques to integrate these models, with the objective of enhancing overall prediction accuracy and mitigating the risk of overfitting.The findings of this study offer valuable insights to the fields of NLP and machine learning and present a novel perspective on leveraging multi-task learning for the twin challenges of fake reviews detection and review helpfulness prediction.

Abstract Research on soil water infiltration in equatorial climates like Indonesia is limited. Despite Papua accounting for 29% of Indonesia’s surface water, there’s a shortage of hydrological data. This study aimed to identify the best infiltration model tailored to the characteristics of basic infiltration rates in Papua’s small watersheds. Observations were made at 95 points across 11 small watersheds in Papua. Based on equatorial basic infiltration rate theories, analysis classified infiltration values against observation time. The performance of four infiltration models — Horton, Philip, Kostiakov, and Green Ampt — were compared. The results indicated the Philip model as superior, with average scores of 0.901 (R), 0.814 (NSE), and 0.424 (RSR), followed by the Horton and Green Ampt models. These three models showed excellent performance. However, the Kostiakov model was found lacking and needs modification. Further research on rapid and very rapid classifications is vital for enhancing infiltration rate predictions in small equatorial watersheds.

Eco-hydrological processes in watersheds are essential for policy development and social growth despite growing environmental concerns.These processes represent a dynamic interaction between the hydrological cycle and ecological elements, with infiltration as one of the important components.According to preliminary studies, the availability of infiltration rate data holds significant importance for irrigation planning, flood management, and water resource studies.Presently, there is a global decrease in hydrological data due to the abundance of water resources in Papua.Existing literature emphasizes the need to evaluate the Kostiakov and Green Ampt models in varied soil textures in Papua, particularly within small watersheds.Therefore, this research compared the performance of the two models on each soil texture using the Hydrological Soil Group classification.It also analyzed modifications for models with unsatisfactory performance through the use of RStudio software analysis with k-fold cross-validation.The results showed that the Green Ampt model performs better than the Kostiakov model for nine soil textures, with average performance values of 0.800 (R), 0.636 (NSE), and 0.588 (RSR).Although the Kostiakov model initially underperformed, it was enhanced to the Kostiakov-Small Watershed Model by integrating soil properties such as water content (w) and porosity (n).Further evaluation in other small watersheds is needed to confirm its robustness.In conclusion, this research filled hydrology data gaps in Papua, which resulted in an infiltration model tailored to the soil characteristics of small watersheds.

Our goal was to identify the practical usage of medication management apps and what they can offer a consumer especially in their old age, keeping in view the aspect of medication adherence.A search of FREE medication management apps was conducted on app store of iPhone/Android operating system. Apps were included if they had a medication management system which included a reminder setup option and had an easy to use interface.Of the 22 apps on IOS and 18 apps on Android identified by strategy all met the inclusion criteria. WebMD and Drugs.com rated the highest among the apps because of their basic medication reminder feature coupled with their enhanced levels of functionality. WebMD was rated best for its information and usability which included a symptom checker, medication reminder, list of disease conditions, drug list with Indications, dosage information, side effects, drug interactions, drug use in pregnancy and lactation, first aid information, local health facilities listings, tests and procedures listings, healthy living tips, food and recipes.Finding a medication management app is challenging if you are looking for a specific type of apps as most of the apps are not tested by any authorized drug regulatory authority for example FDA. Almost all have no reviews and are not affiliated to any healthcare organization. Despite being untested, medication apps represent a possible strategy that pharmacists, healthcare workers, carers and family members of elderly patients can recommend for helping nonadherent patients and incorporate into their practice.Â

Stabilitas tanah merupakan salah satu usaha untuk meningkatkan kapasitas daya dukung tanah. Tanah lempung plastisitas tinggi berpotensi menjadi tanah yang bermasalah karena mempunyai kekuatan rendah dan penurunan yang tinggi. Salah satu metode untuk meningkatkan daya dukung adalah stabilisasi tanah lempung salah satunya menggunakan Portland Cement Type I. Penelitian ini diharapkan untuk mengetahui seberapa besar pengaruh perubahan semen terhadap nilai kuat geser tanah. Dalam penelitian ini tanah yang digunakan berasal dari Jalan Makam Kelurahan Malason, Distrik Aimas, Kabupaten Sorong. Pengujian tanah ini terdiri dari pengujian fisik dan mekanis, pengujian yang utama dilakukan adalah pengujian Direct Shear Test (Uji Kuat Geser Langsung) yang dilakukan di Laboratorium Mekanika Tanah Fakultas Teknik Universitas Muhammadiyah Sorong dan berpedoman pada SNI dengan variasi campuran semen sebesar 2%, 4%, 6%, 8% dan 10%. Dari hasil penelitian didapatkan bahwa semakin besar variasi semen maka tegangan geser, kohesi dan sudut geser semakin meningkat. Nilai tegangan geser, kohesi dan sudut geser yang tertinggi pada penambahan bahan stabilitas sebesar 10% dengan waktu pemeraman 3 hari dengan nilai tegangan geser 0,541 kg/cm² kohesi sebesar 0,172 Kg/cm² dan sudut geser sebesar 42,62°. Hal ini menunjukan bahwa semen dapat dijadikan bahan stabilisasi untuk meningkatkan kekuatan dan daya dukung tanah lempung ditinjau dari peningkatan nilai tegangan geser, kohesi tanah dan sudut geser yang dihasilkan.

Nowadays, humans cannot be separated from information technology; this significantly impacts various fields, especially educational administration. Academic services that were initially manual have now transformed into digital, where academic data, both information and other administration, can now be handled by information systems. This study aimed to determine the effectiveness of implementing the integrated academic information system (SIAT) that has been running in Islamic universities. Data collection was carried out using a descriptive qualitative method concerning the field research approach combined with data triangulation; data collection was obtained by distributing questionnaires, qualitative interviews, and observations. The findings were that SIAT could increase the effectiveness and efficiency of academic services at the Faculty, ease of accessing information, especially in KRS filling activities, KHS checking, lecture monitoring, lecturer grade input, and distribution of lecture schedules can be done in one system. The obstacles felt were few, especially if the system was undergoing maintenance, data loading was hampered, and some students did not understand how to operate the information system. The solution that can be done is to hold periodic socialization regarding the implementation of SIAT and to update the system so that it remains optimal in its operation.

The wood processing industry in Indonesia, especially in the Southwest Papua region, faces ongoing challenges in accurately counting wooden logs, a task traditionally performed manually. Manual methods are time-intensive and prone to error, leading to inefficiencies in operations and weaknesses in resource management. This study addresses these challenges by applying a deep learning-based object detection approach, specifically the You Only Look Once version 8 (YOLOv8) algorithm, to automate the detection and counting of wooden beams in real time. YOLOv8 was chosen for its ability to perform high-speed and accurate detection even under varying environmental conditions, such as different lighting levels and camera angles. The model was trained on a custom dataset consisting of 265 annotated images of wooden beams, with a split of 70% for training, 20% for validation, and 10% for testing. Performance evaluation using a confusion matrix revealed a detection accuracy of 94%. These findings suggest that YOLOv8 is highly effective in supporting automation within wood processing workflows. By reducing dependency on manual labor and minimizing counting errors, the system contributes to more accurate inventory tracking and enhanced productivity. This research demonstrates the potential of integrating AI-driven models into mobile and industrial applications for improved efficiency in forestry-related sectors.

Higher education institutions in the era of digital disruption face challenges in integrating

The global database underscores Indonesia's scant 0.47% global contribution, of which 7.7% is from humid tropical climates. However, existing infiltration studies have primarily focused on specific soil textures and limited research points, resulting in a lack of comprehensive data. This knowledge gap is particularly evident in the Papua region of Indonesia, which boasts many small watersheds with abundant water resources but limited hydrologic data, especially regarding infiltration rates. Previous studies indicated that Horton and Philip's models excelled in equatorial regions but were limited in the number of soil textures and watersheds analysed or focused mainly on larger watersheds. Therefore, this study aimed to address this research gap by conducting a comprehensive analysis of the performance of the Horton and Philip's models across different soil textures in small watersheds, using the Hydrologic Soil Group classification as a reference. A performance analysis was conducted to assess Horton and Philip's performance using the Moriasi technique (based on R, RSR, and NSE best values). Field observations were conducted at 95 points in eleven small watersheds in Papua as representatives of equatorial small watersheds globally. Observations were suspended for 48 hours if rainfall occurred; thus, ten months were needed to finish the observation. The results of this study demonstrated that the Horton model performed exceptionally well for six of nine soil textures, whereas the Philip's model showed excellent performance for five out of nine. The obtained research results were compared with similar studies from Ghana, Nigeria, and India, reinforcing the conclusion that globally, the Horton and Philip's model effectively describes infiltration rates in equatorial small watersheds. Further research was recommended in equatorial small watersheds with sand and loamy sand soil textures, two of the nine soil textures that were not covered in the conducted study.
