Abstract

Industri ritel teknologi menghadapi kompleksitas dalam memahami pola pembelian konsumen untuk optimalisasi strategi pemasaran dan pengelolaan inventaris. Penelitian ini mengimplementasikan algoritma Apriori untuk analisis market basket pada data transaksi toko komputer SentralTek selama periode Desember 2024 hingga Mei 2025. Dataset terdiri dari 3.907 baris transaksi yang terdistribusi dalam 1.421 transaksi unik dengan 665 produk berbeda dalam 48 kategori. Algoritma Apriori diterapkan dengan minimum support 1% dan minimum confidence 30%, menghasilkan 20 frequent itemsets dan 13 association rules yang valid. Hasil menunjukkan dominasi produk tinta printer Epson 003 dengan support tertinggi 4,36% untuk varian Black. Association rule terkuat adalah kombinasi Yellow dan Cyan yang mengarah ke Magenta dengan confidence 95% dan lift 43,55. Validasi model menunjukkan konsistensi 86% antara training dan validation set dengan average lift 40,19. Temuan penelitian memberikan dasar untuk strategi bundling produk dan optimalisasi tata letak toko berdasarkan pola asosiasi yang teridentifikasi, dengan implikasi praktis untuk cross-selling dan manajemen inventaris.

Abstract

Penelitian ini membahas penerapan metode Fuzzy Mamdani untuk memprediksi kondisi cuaca di Kabupaten Tegal dengan memanfaatkan tiga variabel utama, yaitu suhu udara, kelembapan udara, dan kecepatan angin. Data cuaca diperoleh dari BMKG Tegal periode 2024–2025 dan diolah melalui proses fuzzifikasi, pembentukan aturan IF–THEN, inferensi fuzzy, dan defuzzifikasi menggunakan metode centroid. Sistem yang dibangun menghasilkan prediksi cuaca berupa kategori “cerah”, “berawan”, “hujan ringan”, dan “hujan lebat”. Hasil evaluasi menggunakan Mean Absolute Error (MAE) sebesar 0,29 dan Root Mean Squared Error (RMSE) sebesar 1,08 menunjukkan tingkat akurasi yang tinggi dan kesalahan prediksi yang sangat rendah. Dengan demikian, metode Fuzzy Mamdani terbukti efektif dalam menghasilkan prediksi cuaca yang akurat dan relevan, sehingga dapat dimanfaatkan oleh masyarakat, khususnya petani dan nelayan, untuk perencanaan aktivitas serta mitigasi risiko akibat perubahan cuaca mendadak.

Abstract

Digital marketing is promotional activities and market search through the media digitally online by utilizing various means such as social networks. The aim of this research is to increase knowledge and skills about digital marketing, especially social media, for Small and Medium Enterprises (SME) business people to increase their sales and profits. Digital marketing is the use of social media networks to carry out promotional activities and map digital markets. By using computers or other electronic equipment, digital marketing ideas can bring together geographically diverse parties. The aim of this research is to identify the most effective digital marketing tactics for the growth of MSMEs in Tegal City and Tegal Regency. The method used in this research is descriptive qualitative. With Data collection through observation, interviews, and secondary sources, such as books, journals, and articles, were used to collect information for this research. The results of this research show that the productivity growth of MSMEs in Tegal City and Tegal Regency has not been positive. Even when a website for an online business has been created, not everyone has implemented a digital marketing plan. It can be seen that digital marketing strategies have not received much attention from MSMEs in Tegal City and Tegal Regency. So it is hoped that MSMEs in Tegal City and Tegal Regency can adapt to changing times, namely selling online using digital marketing strategies.

Abstract

This research aims to develop a disease and pest detection system in chili plants using computer vision techniques. In this study, deep learning methods, especially Convolutional Neural Networks (CNN), were applied to identify and classify various types of diseases and pests that often attack chili plants. The data used included images of chili leaves infected with various diseases and pests, which were then trained in CNN models to recognize certain patterns that indicate the presence of infection. The results showed that the developed system was able to detect and classify diseases and pests in chili plants with a very high degree of accuracy. The novelty of this research lies in the use of computer vision techniques combined with sophisticated deep learning algorithms to automatically detect diseases and pests, which were previously done manually by farmers or agricultural experts. These findings make an important contribution to improving efficiency and effectiveness in chili crop health management, offering innovative solutions to support agricultural sustainability through the use of advanced technology.

Abstract

The application of the Fuzzy Expert System method in the early detection of dengue fever offers a promising approach to improve diagnostic accuracy. This study aims to develop a system that can overcome the diversity of dengue fever symptoms and uncertainty in the diagnosis process. Using medical record data of patients who have confirmed DHF, the study designed fuzzy rules for symptom evaluation, resulting in more precise diagnostic outputs. The results indicate the system's success in identifying dengue cases with high sensitivity and good positive predictive value. These findings confirm the importance of FES technology in clinical practice, especially for controlling and preventing dengue fever in endemic areas. Continued research will test this system in a broader clinical scenario to ensure its effectiveness and practicality in diverse medical environments.

Abstract

Dengue fever is a tropical disease whose diagnosis is often delayed due to limitations of conventional diagnostic methodologies, which have an impact on the effectiveness of medical interventions. This research is designed to develop an Artificial Neural Network (ANN) model aimed at improving accuracy and speed in dengue diagnosis. Through quantitative methods, clinical data from 50 patients during the period 2020-2021 were analyzed using machine learning techniques to train the ANN model, including the process of data normalization and selection of relevant features. The test results of the model showed excellent diagnostic performance with accuracy reaching 87%, precision 92%, and F1-Score 92%, indicating its effective ability to identify positive and negative cases. The conclusion of this study is that the developed ANN model is able to overcome the limitations of conventional diagnostics and shows significant potential in improving medical responses to dengue outbreaks. Further research is recommended to expand the datasets used in order to improve the validation and generalization of the model in the context of broader clinical applications

Abstract

The chicken farming industry is an important sector in the Indonesian economy, but there are food security issues with the presence of tiren chicken. This research aims to develop a more accurate and efficient method of detection of tiren chickens using Naive Bayes Classifier with Gaussian and Bernoulli kernels and GLCM feature extraction. Data is collected from various internet sources, then pre-processing and feature extraction is carried out. The Naive Bayes Classifier algorithm is implemented with two kernels and evaluated using accuracy, precision, recall, and f1-score metrics. The Gaussian kernel showed an accuracy of 0.75, higher than Bernoulli's kernel which was only 0.50. Models with Gaussian kernels have high performance in detecting tiren chickens and normal chicken precision. The combination of Gaussian and Bernoulli kernels and GLCM feature extraction is effective in improving the detection accuracy of tiren chickens, contributing significantly to food safety and consumer confidence

Abstract

Pengembangan metode prediksi tingkat kerawanan tanah longsor di Kabupaten Brebes menggunakan kombinasi double exponential smoothing dan analytical hierarchy process (AHP). Tujuan penelitian ini adalah meningkatkan pemahaman dan prediksi terhadap fenomena tanah longsor dan memanfaatkan data historis dan analisis kriteria multi-faktor. Metodologi penelitian ini melibatkan analisis seri waktu menggunakan double exponential smoothing untuk memprediksi variabel-variabel penting seperti curah hujan, dan pergerakan tanah. Sementara AHP digunakan untuk menilai dan mengintegrasikan berbagai faktor risiko tanah longsor, termasuk kondisi geologi, kemiringan lereng, dan penggunaan lahan. Hasil penelitian ini adalah model yang diusulkan mampu memprediksi tingkat kerawanan tanah longsor dengan akurasi yang lebih tinggi dibandingkan metode yang ada. Penelitian ini memberikan kontribusi penting dalam upaya mitigasi bencana tanah longsor di Kabupaten Brebes, serta membuka peluang untuk aplikasi metode serupa di wilayah lain yang memiliki risiko tanah longsor.
