Abstract

Abstract: Unhealthy snacks are a common problem among elementary school students due to their lack of knowledge about food safety. This situation is exacerbated by a lack of attention from parents, educators, and schools to the types of snacks consumed by children. Based on the Final Report of the Monitoring and Verification Results of the National School Snack Food Safety Profile (PJAS) over the past 10 years, 98.9% of school children regularly buy snacks, and only about 1% never buy snacks. Furthermore, data from the Food and Drug Monitoring Agency (BPOM) from 2008–2011 shows that 40–44% of school snacks do not meet food safety requirements. This condition poses a risk of food poisoning and has negative impacts on children's health. Objective: This study aims to develop a flip and learn flashcard-based nutrition education media to increase elementary school students' knowledge about the importance of choosing healthy snacks. It is hoped that this media can reduce the number of food poisoning cases caused by unhealthy snacks. Using a posttest-only control group design, which involved administering a posttest to both the control and experimental groups after the intervention was implemented, this study produced educational media in the form of flashcards that were effective in increasing students' understanding of the importance of choosing healthy snacks. Keyword: Nutrition Education, Educational Media, Flashcards, Healthy Children's Snacks, Elementary School Children Abstrak: Jajanan tidak sehat merupakan salah satu masalah yang sering dialami oleh siswa sekolah dasar (SD) karena masih rendahnya pengetahuan mereka tentang keamanan pangan. Kondisi ini diperparah dengan kurangnya perhatian dari orang tua, pendidik, dan pihak sekolah terhadap jenis jajanan yang dikonsumsi anak-anak. Berdasarkan Laporan Akhir Hasil Monitoring dan Verifikasi Profil Keamanan Pangan Jajanan Anak Sekolah (PJAS) Nasional dalam 10 tahun terakhir, tercatat sebanyak 98,9% anak sekolah terbiasa jajan, dan hanya sekitar 1% yang tidak pernah jajan. Selain itu, data dari Badan Pengawas Obat dan Makanan (BPOM) tahun 2008–2011 menunjukkan bahwa 40-44% jajanan sekolah belum memenuhi syarat keamanan pangan. Kondisi ini menimbulkan risiko keracunan ma- kanan dan dampak buruk terhadap kesehatan anak. Tujuan: Penelitian ini bertujuan untuk mengembangkan media edukasi gizi berbasis flashcard flip and learn guna meningkatkan pengetahuan siswa sekolah dasar mengenai pentingnya memilih jajanan sehat. Diharapkan media ini dapat menekan angka keracunan makanan akibat jajanan tidak sehat. Menggunakan desain posttest only control group, yaitu memberikan posttest kepada ke- lompok kontrol dan kelompok eksperimen setelah intervensi dilakukan. Penelitian ini menghasilkan media edukasi berupa flashcard yang efektif dalam meningkatkan pemahaman siswa tentang pentingnya memilih jajanan sehat.

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.

Abstract

Abstract: Rapid population growth and urbanization make solid waste management a pressing environmental and socio-economic challenge. The transition from a linear "take-use-dispose" economy to a restorative and regenerative circular economy model is imperative. This research in-depth analyzes how Community-Based Waste Management (CWBM) initiatives can contribute to achieving a circular economy, focusing on the interacting systematic dynamics. Using a Loop Dynamics approach, this study identifies and examines the complex cause-and-effect relationships and feedback loops in Padang City's waste management ecosystem. Through a quantitative survey of 100 respondents, it was found that the variables studied simultaneously had a significant influence on management success. However, no variable had a significant effect on the outcome. Loop Dynamics modeling revealed reinforcing loops (R1-R6) that drive positive cycles, such as increased revenue from recycling that stimulates participation, and balancing loops (B1-B3) that maintain system balance. These findings confirm that PSBM is not simply a mitigation strategy, but rather a strategic intervention point capable of driving a circular transition, creating local economic opportunities, and supporting the achievement of the Sustainable Development Goals (SDGs). The results of this study are expected to guide policymakers and communities in designing more innovative and adaptive waste management strategies. Keywords: Waste Management, Circular Economy, Loop Dynamics, Sustainable Development. Abstrak: Laju pertumbuhan penduduk dan urbanisasi yang pesat menjadikan pengelolaan sampah sebagai tantangan lingkungan dan sosial-ekonomi yang mendesak. Transisi dari ekonomi linier "ambil-pakai-buang" menuju model ekonomi sirkular yang restoratif dan regeneratif menjadi imperatif. Penelitian ini menganalisis secara mendalam bagaimana inisiatif Pengelolaan Sampah Berbasis Masyarakat (PSBM) dapat berkontribusi pada pencapaian ekonomi sirkular, dengan fokus pada sistematis yang saling berinteraksi. Menggunakan pendekatan Loop Dynamics, studi ini mengidentifikasi dan menguji hubungan sebab-akibat serta umpan balik kompleks di ekosistem pengelolaan sampah Kota Padang. Melalui survei kuantitatif terhadap 100 responden, ditemukan bahwa variabel yang diteliti secara simultan memiliki pengaruh signifikan terhadap keberhasilan pengelolaan. Namun, secara parsial tidak ada variabel yang memiliki pengaruh signifikan. Pemodelan Loop Dynamics mengungkap adanya reinforcing loops (R1-R6) yang mendorong siklus positif, seperti peningkatan pendapatan dari daur ulang yang memicu partisipasi, serta balancing loops (B1-B3) yang menjaga keseimbangan sistem. Temuan ini menegaskan bahwa PSBM bukan sekadar strategi mitigasi, melainkan titik intervensi strategis yang mampu mendorong transisi sirkular, menciptakan peluang ekonomi lokal, dan mendukung pencapaian Tujuan Pembangunan Berkelanjutan (SDGs). Hasil penelitian ini diharapkan dapat menjadi panduan bagi pembuat kebijakan dan komunitas dalam merancang strategi pengelolaan sampah yang lebih inovatif dan adaptif. Kata Kunci: Pengelolaan Sampah, Ekonomi Sirkular, Loop Dynamics, Pembangunan Berkelanjutan.
