Abstract

Predictive Maintenance (PdM) is an adoptable worth strategy when we deal with the maintenance business, due to a necessity of minimizing stop time into a minimum and reduce expenses.  Recently, the research of PdM is now begin in utilizing the artificial intelligence by using the machine data itself and sensors. Data collected then analyzed and modelled so that the decision can be made for the near and next future. One of the popular artificial intelligences in handling such classification problem is Support Vector Machines (SVM). The purpose of the study is to detect machine failure by using the SVM model. The study is using database approach from the model of Machine Learning. The data collection comes from the sensors installed on the machine itself, so that it can predict the failure of machine function. The study also to test the performance and seek for the best parameter value for building a detection model of machine predictive maintenance The result shows based on dataset AI4I 2020 Predictive Maintenance, SVM is able to detect machine failure with the accuracy of 80%.

Abstract

This study analyzes the latest developments and trends in the field of Mobile Ad-Hoc Networks (MANET) through a bibliometric approach using a metadata dataset from publications taken from Scopus between 2021 and 2024. By utilizing VOSviewer to visualize the data, the study identified key keywords that dominated the MANET literature, such as "security", "routing protocols", "mobility", and "5G". The visualization results show several important clusters, including topics related to network security, vehicle networks (VANET), and the application of advanced technologies such as machine learning in network management. Despite the decline in the number of publications in 2023 and 2024, collaboration between authors continues to show a strong trend. The research also highlights various challenges that are still open problems, such as the development of efficient routing protocols, improving network security, and managing resources in a dynamic MANET environment. In addition to the VOSviewer analysis, further exploration was carried out using the built-in visualization tools from the Scopus web platform to enrich the interpretation of emerging topics and research connections. This was followed by a deeper conceptual mapping using Scopus AI, which provided a visual breakdown of interconnected themes such as security issues, routing protocols, and different network types like VANET and FANET. To complement and validate the findings, the study also incorporated evidence based summaries retrieved from Consensus.app, offering additional insights from AI-driven scientific consensus. This multi-platform approach enhances the reliability of the analysis and provides a more comprehensive view of current and future research directions in the MANET domain.

Abstract

This research is motivated by the importance of making teaching materials that are able to awaken students' 6C skills to face the era of the industrial revolution 4.0. The 6C skills referred to in this study include communication skills, critical thinking, collaboration, creativity, citizenship/culture, and character education/connectivity). The purpose of this research is to investigate the feasibility and effectiveness of interactive mathematics teaching materials on probability materials developed in improving the ability to conceptual understanding and critical thinking. The research method used is this development research refers to the 4D model developed by Thiagarajan which includes the stages of define, design, development, and dissemination. The research was conducted at SMA Islamic Village, Kelapa Dua, Tangerang in class XII IPA. Before the teaching materials developed are implemented for students, validation of the teaching materials is carried out which includes validation of material experts, language experts, media experts, and evaluation experts. The results obtained from this study are the teaching materials developed are declared feasible and ready to be used. Based on the results of the analysis using descriptive statistical techniques, the validity of the teaching materials developed is very valid.

Abstract

Nanocellulose has emerged as a promising biomaterial with broad applications across sustainable packaging, biomedical engineering, and environmental remediation. Despite increasing global interest, a comprehensive understanding of the collaborative dynamics and evolving research directions in this field remains limited. This study aims to map the global research landscape of nanocellulose from 2021 to 2025 through an integrative bibliometric and text mining approach. A total of 2,971 scientific articles were retrieved from the Scopus database using a targeted query focused on nanocellulose-related keywords within the materials science domain. The metadata was analyzed using VOSviewer to visualize co-authorship networks, keyword co-occurrence, citation linkages, and bibliographic coupling. Complementary text analysis, including topic modeling via Latent Dirichlet Allocation (LDA), was conducted using Python libraries such as NLTK, spaCy, and Gensim. The results reveal China as the leading country in terms of research output, institutional collaboration, and funding, followed by India and the United States. Key thematic clusters center around biomedical applications, composite development, and water treatment. Highly cited authors and organizations are concentrated in specialized pulp and paper research institutes. This study not only delineates the structure and trajectory of global nanocellulose research but also highlights emerging areas and collaboration patterns. The findings can guide future research investments, inform policy decisions, and foster strategic academic partnerships in the rapidly evolving field of cellulose-based nanomaterials

Abstract

Stunting is a disorder in children caused by chronic nutritional problems. Stunting is usually characterized by a child’s failure to grow and develop optimally. In Indonesia, the government is focusing on addressing of stunting case, as it aims to develop the superior of human resources. In Tangerang regency is currently holding a “Gebrak Tegas” program to address the problem of stunting. The causes of stunting required scientific study to help the government understand the scientific factors that causing stunting. Therefore, this study aims to analyze the factors causing stunting the children in the Tangerang regency. The data analysis method in this study use the Seemingly Unrelated Regression (SUR), which is integrated with a machine learning, namely Random Forest. The data used in this study were obtained from primary data through questionnaires. The subjects of this study were parents of stunting and non-stunting children who were at “Posyandu” under of “Kelapa dua” and “Binong” health centers. Sampling method in this study is purposive-random sampling. The results of the data analysis showed that the five variables from the factors measured had the most significant influence, namely nutritional, socio-economi, and pregnancy and childbirth history factors. Five variables that influence children stunting are animal protein, which has the highest probability of 87.5% when the children consumes protein once or twice a week. The children consume vitamin A twice has a 97% probability. The source of income for the parents, whether from the private or self-employment, has a probability of over 90%. Furthermore, the consumption of iron-boosting tablets by mother during pregnancy and the amount of income from the parents have a probability of 84%.

Abstract

To produce quality oil, proper plant care is essential, with fertilization being key to maintaining high productivity. As the plant ages, the required fertilizer quantity decreases, which can impact production outcomes. To assess the effects of reduced fertilization, observations were made on oil palm plants with decreased fertilizer quantities. These observations focused on plant health and oil palm production results. Analyzing plant health can be done in various ways, one of which is by using remote sensing technology. Remote sensing analysis of plant health can be conducted using Sentinel 2A satellite imagery, accessible and downloadable via Google Earth Engine. NDVI analysis is used on Sentinel 2A imagery to assess plant health. The analysis results show consistent health classification across different planting years (0.72-1), indicate a very healthy classification, demonstrating that reducing the quantity of fertilizer does not affect the NDVI values in different planting years. However, reducing the quantity of fertilizer does impact the productivity of oil palm plants. These findings provide an important contribution to fertilizer management, particularly in oil palm plantations.
