Abstract

Starfruit is one of the fruits that are widely cultivated in Indonesia. But at this time sorting of starfruit is stilldone manually by humans, consequently resulting in a uniform level of maturity that is not good. For thisreason, a system is needed that can identify the level of maturity of starfruit with artificial neural networks.The main problem of designing artificial neural networks is how to analyze and design an artificial neuralnetwork architecture in order to determine the maturity level of sweet starfruit properly. This study aims todesign artificial neural networks with backpropagation method to identify the maturity level of starfruit.From the results of the study, the best configuring of backpropagation artificial neural network model is amodel of artificial neural networks with 3 inputs, 11 hidden layer neurons and 3 outputs (3-11-3). With thisconfiguration, artificial neural networks are able to identify the level of maturity with a success rate of 95.8%of 48 starfruit test data.

Abstract

Gempa bumi merupakan salah satu bencana alam yang sulit diprediksi namun memiliki dampak besar terhadap kehidupan manusia. Oleh karena itu, diperlukan suatu pendekatan analitis yang mampu mengidentifikasi pola dan hubungan antarparameter gempa untuk mendukung sistem peringatan dini. Penelitian ini bertujuan untuk melakukan Klasifikasi Dampak akan kejadian gempa bumi menggunakan metode Data Mining berbasis Decision Tree. Data yang digunakan berasal dari katalog gempa yang memuat atribut seperti Tanggal Kejadian (timestamp), magnitudo, kedalaman, serta koordinat lokasi (latitude dan longitude). Proses analisis meliputi tahap pembersihan data (data cleaning), transformasi, dan pembuatan model klasifikasi Decision Tree untuk menentukan tingkat potensi dan dampak gempa serta mengetahui keakuratan gempa bumi berdasarkan data dari tahun ketahun. Hasil penelitian menunjukkan bahwa atribut magnitudo memiliki pengaruh signifikan terhadap tingkat risiko gempa. Model Decision Tree yang dibangun mampu menghasilkan aturan klasifikasi seperti “Jika magnitudo <5 maka berpotensi Risiko gempa bumi rendah, sedangkan magnitudo antara 5-7 berisiko gempa bumi sedang, dan magnitudo ≥ 7 maka berpotensi Risiko Gempa Bumi Tinggi”, yang dapat digunakan untuk mendukung pengambilan keputusan dalam mitigasi bencana. Dengan demikian, metode Decision Tree terbukti efektif dalam mengungkap pola tersembunyi dari data gempa bumi dan dapat menjadi dasar bagi sistem prediksi serta peringatan dini gempa di masa mendatang. Disimpulkan bahwa akurasi masing – masing sebesar 100 %, sedangkan recall sebesar 100 % tapi hasil precision menunjukkan statistik yang berbeda yakni Prediksi Tidak Berpotensi Gempa Bumi  Besar sebesar 100%, sedangkan Prediksi Tidak berpotensi Gempa Bumi sedang sebesar 99,67%, dan terakhir prediksi Tidak berpotensi Gempa Bumi Kecil sebesar 96 %. Hasil pengujian ternyata menghasilkan magnitude rendah dengan ukuran >5,350 tergolong rendah, sedangkan magnitude rendah dengan ukuran <5,350 mempunyai frekuensi yang banyak. Dan Beberapa data berdasarkan statistik Magnitudo >5.350 ukuran sedang dari data sebanyak 16 data. Sedangkan magnitudo ≤ 5.350 Ukuran Rendah sebanyak 6716 Data yang ditemukan dan sudah dianalisis.

Abstract

Stroke is a serious disease that requires prompt and appropriate treatment; therefore, determining the level of patient Emenrgency Levels is critically important. This study aims to develop a web-based application for predicting the Emenrgency Levels level of stroke patients using the Naïve Bayes algorithm as a classification method. The research data were obtained from the medical records of stroke patients at RSUP Dr. M. Djamil Padang during March and April 2025, with a total of 222 data samples. The attributes used in this study include age, gender, address, length of stay, ward class, BPJS insurance membership status, and comorbidities, with Emenrgency Levels status as the class attribute classified into Emenrgency and non-Emenrgency. The application was developed as a web-based system to facilitate easy access for medical personnel in utilizing the prediction system. The experimental results indicate that the Naïve Bayes algorithm achieved an accuracy of 77.48% with an error rate of 22.52%. The findings of this study are expected to assist medical personnel in supporting faster and more objective decision-making regarding the Emenrgency Levels level of stroke patients.

Abstract

Global rice production faces mounting pressure from population growth and climate change, yet traditional statistical models fail to capture the complex nonlinear dynamics between environmental factors and crop yields. To address this gap, this study systematically compares the accuracy of three machine learning algorithms, Support Vector Machine (SVM), Random Forest (RF), and Naïve Bayes (NB) for predicting rice production fluctuations due to climate change using the latest local climate data from Indonesia. A dataset of 96 monthly observations (2018–2025) comprising climate features (temperature, humidity, wind speed, precipitation, cloud cover, sunshine duration) and rice production categories (Low, Medium, High) was analyzed. Algorithm performance was evaluated using accuracy, precision, recall, and F1-score. The results demonstrate that Random Forest significantly outperforms the other methods, achieving an accuracy of 95%, precision of 0.9571, recall of 0.95, and F1-score of 0.95, compared to SVM (75% accuracy) and Naïve Bayes (70% accuracy). This study provides the first head-to-head comparison of these three algorithms for rice yield prediction in Indonesia using current climate data. The key benefit over pre-existing approaches is the empirical confirmation that ensemble learning, particularly Random Forest, offers superior predictive reliability for crop yield forecasting under high feature complexity, thereby enabling more accurate, data-driven agricultural policy and food security planning.

Abstract

Teknologi imersif seperti Augmented Reality (AR) dan Virtual Reality (VR) telah menciptakan peluang baru dalam bidang pendidikan. Namun, masih ada perdebatan tentang teknologi mana yang dapat meningkatkan hasil pembelajaran. Tujuan dari penelitian ini adalah untuk membandingkan efektivitas realitas maya (AR) dan realitas virtual (VR) sebagai media pembelajaran dengan menggunakan pendekatan Systematic Literature Review (SLR) yang didasarkan pada PRISMA 2020. Tiga basis data utama (Scopus, IEEE Xplore, dan ScienceDirect) digunakan untuk melakukan pencarian literatur dari tahun 2019 hingga tahun 2020. Dari 562 artikel yang ditemukan, 42 memenuhi persyaratan inklusi dan dianalisis secara naratif-komparatif. Hasil penelitian menunjukkan bahwa dibandingkan dengan metode konvensional, kedua teknologi meningkatkan motivasi, keterlibatan, dan hasil belajar. Sementara realitas virtual memiliki keunggulan dalam simulasi skenario berbahaya, retensi materi kompleks, dan imersi mendalam, AR unggul dalam aksesibilitas, kemudahan adopsi, dan integrasi konteks dunia nyata. Bahasa, STEM, dan kedokteran adalah bidang yang paling banyak memanfaatkan keduanya. Biaya perangkat, kesiapan guru, dan infrastruktur adalah masalah utama, terutama di negara berkembang. Studi ini membantu memilih teknologi berdasarkan tujuan pembelajaran dan konteks institusi. Kata kunci—Augmented reality, Virtual reality, Efektivitas Pembelajaran, Media Pembelajaran, Systematic Literature Review.

Abstract

This study analyzes the influence of WhatsApp Business features (Broadcast Message, Quick Reply, Catalog, and Labeling) on marketing communication effectiveness among creative SMEs in Jambi City. Using a mixed methods approach, the results indicate that WhatsApp Business features collectively have a significant effect on marketing communication effectiveness (R² = 0.596, p = 0.003), explaining 59.6% of the variance. Among the four features, only the Catalog feature showed a significant positive influence (β = 0.903, p = 0.034), highlighting its critical role in enhancing customer communication and engagement. The novelty of this research lies in its focus on creative SMEs producing cultural heritage based products in Jambi and its simultaneous evaluation of four key WhatsApp Business features. The findings suggest that SMEs should prioritize optimizing Catalog features through high quality visual content that effectively communicates product value and local cultural identity, while policymakers should support targeted digital literacy programs for heritage based businesses.

Abstract

Penelitian ini menerapkan algoritma K‑Means untuk mengidentifikasi pola iklim dominan di Provinsi Jambi pada periode Januari 2020 sampai Desember 2024. Dataset bulanan berjumlah 60 observasi yang memuat enam variabel meteorologi: curah hujan, suhu rata‑rata, suhu maksimum, suhu minimum, kecepatan angin, dan kelembaban relatif. Data diagregasi dari data harian menjadi bulanan dan dipra‑proses dengan standardisasi Z‑Score untuk mengatasi heterogenitas skala antar fitur. Penentuan jumlah klaster optimal dilakukan secara kuantitatif menggunakan Elbow Method berdasarkan nilai inersia, yang menunjukkan titik belok pada k=3. Model K‑Means diinisialisasi secara acak dan dijalankan dengan beberapa pengulangan untuk menilai stabilitas hasil; keluaran divisualisasikan dalam proyeksi 2D dan 3D untuk memudahkan interpretasi spasial. Analisis centroid mengidentifikasi tiga rezim iklim: rezim kering/transisi (curah hujan rendah dan suhu relatif tinggi), rezim monsonal normal (curah hujan menengah‑tinggi dan kelembaban tinggi), serta rezim basah ekstrem (curah hujan sangat tinggi dan kelembaban tinggi). Hasil ini menyediakan tipologi iklim berbasis data yang relevan untuk perencanaan pertanian, mitigasi bencana hidrometeorologi, dan kebijakan adaptasi iklim di tingkat provinsi.
