Abstract

Penyakit pada ayam petelur dapat menyebar cepat dalam satu kandang dan berisiko menyebabkan kematian massal. Keterbatasan akses dokter hewan yang hanya berkunjung setiap satu hingga dua bulan sekali memperlambat penanganan ketika ayam sakit. Penelitian ini bertujuan mengimplementasikan algoritma Fuzzy Membership Function dan Naive Bayes untuk membantu peternak dalam mengidentifikasi penyakit ayam petelur secara dini. Fuzzy Membership Function digunakan untuk mengubah data suhu, misalnya 37,2°C menjadi nilai fuzzy 0,483, yang kemudian diintegrasikan dengan dataset gejala penyakit pada Naive Bayes untuk menghitung probabilitas penyakit tertinggi. Pengukuran akurasi dilakukan dengan metode Accuracy Rate menunjukkan tingkat akurasi 93% dari 100 data uji, dengan 93 diagnosis tepat dan 7 tidak sesuai. Walaupun akurasinya cukup tinggi, hasil algoritma ini masih mengalami kesulitan dalam mendiagnosis penyakit dengan gejala ringan atau mirip antar penyakit.

Abstract

Pertumbuhan e-commerce meningkatkan jumlah ulasan konsumen yang dapat menjadi sumber informasi penting bagi produsen. Namun, ulasan tersebut sering ditulis dengan bahasa tidak baku sehingga sulit dianalisis secara manual. Penelitian ini bertujuan untuk mengetahui sentimen konsumen terhadap Emina Daily Matte Loose Powder di Emina Official Shop serta menilai efektivitas metode Support Vector Machine (SVM) dalam klasifikasi sentimen. Sebanyak 1.000 ulasan konsumen dikumpulkan dari Shopee dengan teknik web scraping. Data diproses melalui tahapan pembersihan teks, casefolding, penghapusan stopwords, stemming, dan tokenisasi. Representasi data dilakukan menggunakan TF-IDF, kemudian diklasifikasikan dengan SVM kernel Radial Basis Function (RBF). Hasil penelitian menunjukkan distribusi ulasan didominasi oleh sentimen positif, sedangkan model SVM menghasilkan akurasi 70%. Metode SVM dengan kernel RBF terbukti efektif dalam mengklasifikasikan sentimen produk kecantikan.

Abstract

This study aims to analyze customer review sentiments for Mie Gacoan restaurant in Blitar City through the Grab application using the Support Vector Machine (SVM) algorithm. Customer reviews are categorized into three sentiment classes: positive, negative, and neutral. And the total amount of data used is 991 data. The research process includes manual data collection, text preprocessing, weighting using the TF-IDF method, and classification with the SVM algorithm. Model performance is evaluated using a confusion matrix with precision, recall, and F1-score metrics. And for the testing of the algorithm method using Grid Search and Cross Validation. The results show that the linear kernel achieves the best performance with an F1-score of 0.4649. Positive sentiment dominates the reviews, while negative and neutral sentiments are less prevalent. This study demonstrates that SVM is effective for classifying sentiments in customer reviews and can assist restaurant managers in identifying areas for service improvement.

Abstract

This research presents the development of SiPuTiH (Handwritten Hijaiyah Character Recognition System) using the Convolutional Neural Network (CNN) algorithm to address the challenges of handwriting variability in Arabic scripts. The methodology includes dataset acquisition and preprocessing, CNN architecture design, model training, and performance evaluation. The dataset consists of 1,680 handwritten images representing 30 Hijaiyah characters, divided into 80% training and 20% testing data. The proposed CNN architecture employs four convolutional and pooling layers with a total of 6.8 million trainable parameters. Experimental results show that SiPuTiH achieved a 99.7% accuracy rate in recognizing Hijaiyah characters, with only one misclassification between ‘ta’ (ت) and ‘tsa’ (ث) due to morphological similarity. The trained model was implemented in an interactive Streamlit-based application that includes learning modules, quizzes, and real-time handwriting prediction. SiPuTiH demonstrates high reliability not only as a handwriting recognition system but also as an engaging educational platform for learning Arabic letters. This study confirms the effectiveness of CNNs in handling the morphological complexity of Hijaiyah characters and contributes to the development of intelligent educational tools. Future work may explore larger datasets, transfer learning architectures, and contextual (word-level) recognition to enhance system scalability and performance.

Abstract

TREND store is a retail outlet that sells various types of clothing and accessories. As market competition intensifies, the store needs to develop more efficient marketing strategies to remain competitive. One approach is to utilise sales data to analyse consumer purchasing patterns, given that such data has not been optimally used previously. This study aims to identify purchasing patterns and generate association rules as a basis for marketing strategies using the FP-Growth algorithm. The algorithm was chosen because it can identify frequent itemsets without candidate generation, making it more efficient than other methods in market basket analysis. The research data consist of 64 sales transactions from March 2025. In addition to pattern discovery, lift ratios were calculated to measure the strength of relationships between items. The results show that FP-Growth successfully identified significant purchasing patterns and generated relevant association rules. Several rules have lift ratios above 1, such as 1.2472 and 1.1463 for the combination K7, K1, C5, indicating positive relationships. These findings can be used to develop more data-driven and efficient marketing strategies, such as placing related items together to encourage impulsive purchases, supporting product recommendations, promoting planning, and informing other marketing decisions.

Abstract

This research is motivated by the management  of stunting data  at the Selopuro Health Center UPT which is still manual, spreadsheet-based, prone to errors, and makes it difficult to visualize the distribution of cases. The research aims to design, implement, and test a  WebGIS-Based Stunting Case Distribution Area Application using the Rapid Application Development (RAD) method. The system design successfully aligns needs through the requirements planning, user design, construction, and cutover phases. The intensive iteration process (test and refine) in the user design phase  with the health center succeeded in finalizing the  system prototype, which included the flow of the system, the practicality of  the anthropometric input form, and the clarity of the visualization of map color gradients. The implementation of the system uses PHP with  the Laravel framework and the PostgreSQL database to map geospatial cases through thematic maps in eight villages. The results of the Alpha Testing test with the Blackbox technique  showed a functional validity of 93.1%, beta testing of IT experts reached 95.53% of technical feasibility, and user acceptance of  puskesmas staff reached 93.5%. In conclusion, the RAD iteration is able to quickly align field needs. The practical implication of this system is the availability of precise decision support instruments for Forkopimcam Selopuro in the allocation  of targeted stunting handling assistance .

Abstract

The RT/RW-Net ADC-Net network in Suruhwadang Village with more than 300 customers faces connection instability and security vulnerabilities due to conventional static IP management on a flat network architecture. This research aims to design and implement a MikroTik-based PPPoE network to provide a centralized authentication system and client isolation using the Network Development Life Cycle (NDLC) method. The functional evaluation of the system is tested through Black Box Testing. The test results of 3 clients through 9 test scenarios recorded 100% absolute success. The client isolation feature has been proven to be effective in mitigating local cyberattacks such as ARP Spoofing and NetCut through blocking communication between users with  a 100% Request Timed Out (RTO) status. The  dynamic Simple Queue feature  is precisely able to distribute bandwidth according to regular (5Mbps), gaming (10Mbps), and premium (20Mbps) service packages. In addition to improving stability and security, the system delivers massive operational efficiencies for administrators by cutting activation procedures from 4 manual stages to 2 automatic. In conclusion, the MikroTik-based PPPoE protocol is effective and feasible to be used as a standard for centralized communal network governance.
