Abstract

SME resilience has become a strategic issue because small and medium enterprises operate in increasingly turbulent environments shaped by crises, market shifts, supply chain disruptions, and rapid digitalization, while the technology management perspective provides a relevant lens for explaining how SMEs survive, adapt, and recover. This study aims to identify the determinants of SME resilience from a technology management perspective and to synthesize the conceptual relationships among variables as a foundation for developing a system dynamics model. The study employs a PRISMA-based Systematic Literature Review using four databases, namely Scopus, Taylor & Francis, IEEE, and ScienceDirect, resulting in 18 included articles. The findings show that the determinants of SME resilience can be grouped into four major categories: internal technological capabilities, managerial and organizational capabilities, external environment and ecosystem support, and resilience outcomes. The most dominant variables in the literature include digital transformation, dynamic capabilities, IT capability, digital capability, absorptive capability, organizational agility, and government support. The conceptual synthesis further reveals that technology-related factors rarely influence resilience directly, but rather operate through mediating mechanisms such as digital transformation, organizational agility, ambidexterity, and strategic flexibility. The novelty of this study lies in its synthesis of SME resilience determinants from a technology management perspective that is explicitly directed toward supporting the development of a system dynamics model. Accordingly, this review does not merely identify the determinants of SME resilience, but also organizes them into a conceptual foundation for modelling dynamic and interconnected causal relationships.

Abstract

Metabolic syndrome (MetS) and diabetes mellitus (DM) have become primary concerns worldwide, especially among the younger population. The Indonesian Boarding School model (IBS/Boarding School) is a large education system with a significant number of pupils (teenagers) and has the potential to become a center for metabolic disease, particularly among teenagers, due to their daily intake. This study aimed to provide a baseline screening for MetS and the risk of DM development in Boarding School teenagers. During this observational study, 90 healthy serological samples were obtained from senior and junior high school students. The circulating level of betatrophin was measured using a human betatrophin ELISA kit. Additionally, metabolic syndrome and DM screening data were analyzed using a rapid reverse-flow immunochromatography kit for 65 kDa glutamic acid decarboxylase (GAD65). Among the 90 healthy students, a high prevalence of GAD65 was observed, indicating a potential risk factor for metabolic diseases. Furthermore, higher serum betatrophin levels were observed in the samples. The circulating level of betatrophin was found to have a significant correlation with age, gender, body mass index (BMI), systolic blood pressure (SBP), fasting blood glucose (FBG), sleeping duration, and duration of stay at Boarding School (p < 0.05). Betatrophin emerged as a potential predictor of BMI, SBP, and FBG in students (p < 0.05). Both betatrophin and GAD65 have shown promise as future biomarkers, opening up a new avenue for assessing metabolic syndrome and the risk of DM. This underscores the importance of future programs in Boarding Schools focusing on MetS and DM prevention management, making the audience feel the significance of their work in addressing these pressing health issues.

Abstract

Abstract: Machine learning (ML) models are frequently characterized as "black boxes" due to their complexity, which renders them difficult for humans to interpret. Model interpretability is crucial for understanding the underlying drivers of specific predictions. In the context of mining operations, explaining the fuel consumption rate (FCR) patterns of mining haul trucks through predictive modeling is essential; however, engineers often struggle to identify the most significant contributors quickly and easily. Because standard ML models do not disclose the logic behind their decisions, engineers face ambiguity when analyzing conditions and prioritizing necessary repairs. Such prioritization is vital, as maintenance costs, technical difficulty, and downtime directly impact productivity. Consequently, a model-agnostic approach is required to bridge this gap. This research aims to develop a predictive model to analyze FCR behavior and patterns, subsequently interpreting them through model-agnostic techniques. The study utilized Vehicle Health Monitoring System (VHMS) data from August 2024 to February 2025, incorporating outlier and multicollinearity management. The Random Forest Regressor (RFR) was employed as the primary machine learning algorithm. Global interpretations were conducted using Partial Dependence Plots (PDP), Feature Interaction, and Permutation Feature Importance, while local interpretations were performed using Local Interpretable Model-Agnostic Explanations (LIME) and Shapley Values (SHAP). The performance evaluation results demonstrate that the RFR predictive model maintains consistent performance regardless of the data treatment applied. The optimal configuration was the RFR model without normalization or outlier handling, achieving an RMSE of 3.7312, a SMAPE of 4.64%, and an R-squared of 0.7936. Both global and local interpretations identified engine speed, road angle, and boost pressure as the top three factors significantly contributing to FCR. Keywords: Fuel Consumption Rate; Interpretable Machine Learning; Agnostic Model; Random Forest Abstrak: Model machine learning (ML) sering disebut sebagai “Black-Box” karena kerumitannya sehingga sulit diinterpretasikan oleh manusia. Interpretabilitas model menjadi sangat penting untuk memahami penyebab sebuah prediksi tertentu dibuat. Salah satunya dalam memahami perilaku dan menjelaskan pola fuel consumption rate (FCR) dari mining haul truck menggunakan model prediksi. Seorang engineer akan kesulitan untuk menentukan kontributor paling signifikan secara mudah dan cepat. Pada sebuah prediksi, sebuah model ML tidak akan memberi tahu bagaimana sampai pada sebuah keputusan. Hal ini akan menimbulkan kebingungan engineer pada saat akan menganalisa kondisi dan menentukan prioritas perbaikan yang diperlukan. Prioritisasi perbaikan perlu dilakukan karena pertimbangan biaya, tingkat kesulitan, dan downtime yang sangat mempengaruhi produktivitas. Oleh karena itu, pendekatan model agnostik perlu dilakukan. Penelitian ini bertujuan untuk menghasilkan model prediksi untuk memahami perilaku dan pola FCR kemudian menginterpretasikannya dengan model agnostik. Penelitian ini menggunakan data Vehicle Health Monitoring System (VHMS) dari Agustus 2024 hingga Februari 2025 dengan penanganan outlier dan multikolinieritas. Algoritma ML yang digunakan adalah Random Forest Regressor (RFR). Model agnostik yang digunakan untuk interpretasi global adalah Partial Dependence Plot (PDP), Feature Interaction, dan Permutation Feature Importance. Sedangkan interpretasi lokal menggunakan Local Interpretable Model-Agnostic Explanations (LIME) dan Shapley Value (SHAP). Hasil evaluasi performa model menunjukkan bahwa model prediksi RFR memiliki performa yang konsisten bagaimanapun perlakuan data diterapkan. Model prediksi terbaik yang dipilih adalah model RFR Tanpa Normalisasi – Tanpa Penanganan Outlier dengan nilai RMSE 3,7312, SMAPE 4,64%, dan R-Squared 0,7936. Hasil interpretasi global dan lokal menunjukkan bahwa top three faktor yang berkontribusi signifikan terhadap FCR adalah engine speed, road angle, dan boost pressure.
