Abstract

The quality of sapodilla fruit is a crucial factor in ensuring product standards and consumer satisfaction. This study aims to detect the quality of sapodilla fruit using the Gray Level Co-occurrence Matrix (GLCM) method for texture feature extraction and Support Vector Machine (SVM) as the classification algorithm. A dataset of sapodilla fruit images was collected and processed using data augmentation techniques to enhance image variation. Extracted features, including contrast, homogeneity, energy, and correlation, were used as input for the SVM model. The model was developed using a train-test split approach and evaluated based on accuracy, precision, recall, and F1-score. Experimental results show that the proposed method successfully classifies sapodilla fruit into three categories—raw, ripe, and damaged—with an accuracy of 85%. This model was implemented in a MATLAB-based Graphical User Interface (GUI), enabling users to automatically classify sapodilla quality easily and efficiently.

Abstract

Saat ini data kejadian bencana yang ada di Badan Penanggulangan Bencana Daerah kabupaten Bojonegoro hanya berupa angka-angka kejadian bencana alam dan belum disajikan dalam bentuk peta. Olehkarena itu diperlukan penelitian untuk melakukan pemetaan daerah rawan bencana di kabupaten Bojonegoro. Dari penelitian ini akan menjadi acuan dalam mengakomodir kegiatan mitigasi bencana di kabupaten Bojonegoro. Pada penelitian ini menggunakan metode clustering yakni metode K-Means, K-Medoids, dan X-Means untuk melakukan evaluasi banyaknya cluster yang optimal dan mengembangkan hasil pengelompokan dalam bentuk peta. Data yang digunakan adalah data jumlah kejadian bencana di kabupaten Bojonegoro tahun 2022 yang meliputi jumlah kejadian akibat banjir, jumlah kejadian akibat cuaca ekstrim, jumlah kejadian akibat kebakaran hutan dan lahan, jumlah kejadian akibat kebakaran rumah, jumlah kejadian akibat kekeringan, jumlah kejadian akibat tanah longsor dan jumlah kejadian lain-lain. Berdasarkan nilai Davies Bouldin Index didapatkan hasil bahwa X-Means merupakan metode terbaik dalam pengelompokan wilayah rawan bencana di kabupaten Bojonegoro. Adapun banyaknya cluster yang terbentuk adalah 4 cluster yakni cluster 0 yang terdiri dari 18 kecamatan, cluster 1 yang terdiri dari 7 kecamatan, cluster 2 yang terdiri dari 1 kecamatan dan cluster 3 yang terdiri dari 2 kecamatan. Berdasarkan karakteristik dari hasil pengelompokan dapat disimpulkan bahwa daerah yang paling rawan terjadi bencana di kabupaten Bojonegoro adalah kecamatan Bojonegoro disusul dengan kecamatan Kedungadem dan Temayang.

Abstract

Breast Cancer atau Kanker payudara adalah penyakit yang paling umum ditemukan pada wanita di seluruh dunia. Setiap perkembangan untuk prediksi dan diagnosis penyakit kanker merupakan modal penting untuk hidup sehat. Sehingga, akurasi tinggi dalam prediksi kanker penting untuk memperbarui aspek pengobatan dan standar kelangsungan hidup pasien. Teknik Machine Learning (ML) merupakan aplikasi dari Artificial Intelligence (AI) yang dapat memberikan kontribusi besar pada proses prediksi dan diagnosis dini kanker payudara, dan telah terbukti sebagai teknik yang kuat. Dalam penelitian ini, diterapkan algoritma Machine Learning yaitu metode single: Support Vector Machine (SVM), Random Forest, Logistic Regression, dan K-Nearest Neighbors (KNN) dan metode ensemble yaitu SMOTE-Boosting dan SMOTE-Bagging pada dataset Breast Cancer di Bojonegoro. Tujuan dari penelitian ini Mendaptakan ketepatan klasifikasi atau prediksi breast cancer khususnya studi kasus di Bojonegoro dengan tingkat kinerja yang lebih baik. Nilai akurasi yang terbaik pada metode single yaitu model Random Forest (RF) sebesar 95,65% untuk data testing, 100% untuk data training sedangkan untuk metode ensembel SMOTE-Boosting Random Forest (RF) sebesar 100% untuk data testing, 100% untuk data training dan SMOTE-Bagging RF sebesar 97% untuk data training dan 100% untuk data testing. Sehingga SMOTE-Boosting RF dapat dijadikan analisis prediksi yang terbaik dalam penelitian ini. Hasil ini dapat digunakan di masa depan untuk memprediksi penyakit lainnya.

Abstract

This study forecasts rice production in East Java using Triple Exponential Smoothing (Holt-Winters) and Decomposition. Data includes rice production in dry milled grain (GKG) from January 2018 until December 2023, sourced from the Central Statistics Agency (BPS) of East Java. The analysis identifies the Holt-Winters Multiplicative model as the most effective, with the lowest error values: Mean Absolute Percentage Error (MAPE) of 0.1452, Mean Absolute Deviation (MAD) of 0.1078, and Mean Squared Error (MSE) of 0.0286 during training, and MAPE of 0.1974, MAD of 0.1909, and MSE of 0.0858 during testing. The Holt-Winters Multiplicative model is recommended for future rice production predictions, providing reliable method for accurate forecasting, and aiding in future rice demand planning in East Java.

Abstract

Oral and dental health is an important part of supporting children's growth and development. One simple way to maintain dental health is getting into the habit of brushing teeth regularly with the correct technique. However, school-age children still need education and guidance to have the right knowledge and skills in keeping their teeth and mouth clean. This community service activity aims to improve children's knowledge and skills in proper tooth brushing through education, demonstration, and hands-on practice. The activity was carried out at Kuncup Mekar Kindergarten in Sidorejo, using an educational and participatory approach that includes preparation, oral and dental health education, demonstration, tooth brushing practice, and evaluation. The material provided includes the importance of maintaining dental health, the right time to brush teeth, the use of toothbrushes and toothpaste, and techniques to clean teeth thoroughly. The results show that participants engaged in the activities enthusiastically and actively during both the educational sessions and practical exercises. Participants gained a better understanding of the importance of dental hygiene and were able to practice the steps of brushing teeth according to the given examples with guidance. Educational activities combined with demonstrations and hands-on practice can be an effective approach to instill knowledge and skills for maintaining dental health in children. The continuity of these activities needs to be supported through guidance from teachers and parents so that proper brushing habits can be applied regularly in daily life.
