Abstract

A brand is very dependent on consumer perceptions of the product or services. In assessing consumer perceptions of products and services, companies are often faced with data analysis problems. One of the data that is very useful to produce a picture of consumer perceptions of the products and services is review data. So that the company's ability to process review data means that the company has a picture of the strength of the brand it has. Some of the most popular machine learning algorithms for creating text classification models include the naive Bayes family of algorithms, support vector machines (SVM) and deep learning algorithms. In this research, SVM has been proven to be a reliable method in pattern recognition. In particular, this study aims to produce a model that can be used to classify the polarity of hotel reviews automatically. The experimental data comes from review data on hotels in Europe sourced from TripAdvisor with a total of 38000 reviews. We also measure the quality of the classification engine model. The test results of the SVM model built from hotel review data are quite good. The average accuracy of the classification engine is 92.48%. Because the recall and precision values ​​are balanced, the accuracy value is considered sufficient to describe the quality of the classification.

Abstract

Warung Babi Guling X merupakan salah satu usaha kuliner babi guling yang ada di Bali. Mengacu pada temuan dari wawancara serta observasi memiliki 3 divisi salah satunya adalah divisi kandang babi. Maksud dari penelitian ialah guna menganalisis proses bisnis Warung Babi Guling X dengan hasil pada setiap metode dapat dijadikan acuan untuk mengambil sebuah keputusan. Terdapat permasalahan pada proses pengembangbiakan babi sering kali tidak tepat sasaran dari jadwal masa kawin hingga proses pemisahan dengan induk babi. Dalam hasil identifikasi mempergunakan metode Failure Mode and Effect Analysis (FMEA) diperoleh hasil dengan nilai RPN tertinggi 448 yaitu Ketidaktepatan ketika memperkirakan tanggal kosong. Selanjutnya, dari hasil tersebut mempergunakan metode Business Process Improvement (BPI)  diberikan rekomendasi proses bisnis melalui 2 rekomendasi diantaranya 1) Perlu dilakukan pembuatan SOP pencatatan dengan tools Standarization dan Value-added Assesment, 2) Pembuatan sistem informasi pencatatan dengan tools Automation. Hasil dari rekomendasi tersebut disimulasikan mempergunakan Bizagi Modeler pada 3 level yaitu process validation, time analysis, serta resource analysis adapun hasil simulasi tersebut sebagai berikut 1) level time analysis mengalami peningkatan senilai 2.86% dengan selisih waktu 5 menit, 2) level resource analysis kepala kandang mengalami penurunan beban kerja dan staff mengalami kenaikan beban kerja.

Abstract

This study compares two multi-criteria Decision Support System (DSS) methods, Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) and Weighted Aggregated Sum Product Assessment (WASPAS), for ranking natural tourism destinations in Banyuwangi Regency, Indonesia. Using a quantitative design, survey data were collected from 50 respondents who assessed 48 destinations using five criteria like facilities, entrance fee, safety, travel distance, and cleanliness. The analysis followed the CRISP-DM framework from business understanding through evaluation and interpretation. The MOORA method applied vector normalization and benefit cost optimization, while the WASPAS method combined weighted sum and weighted product models to produce preference scores. Results show that Bangsring Underwater emerged as the most competitive destination overall, achieving preference values of 0.1932 using MOORA and 0.6837 using WASPAS for Decision Maker 1. Sensitivity testing across ten weight variation scenarios indicated that WASPAS showed stronger individual level dominance, ranking the top alternative first in 8 of 10 scenarios, while MOORA ranked first in 7 of 10 scenarios. However, when extended to all respondents, MOORA demonstrated higher population level robustness and slightly higher average accuracy at 51.61% than WASPAS at 50.32%. These findings indicate a trade-off between stability and responsiveness. MOORA is preferable for generalized tourism planning involving diverse stakeholders, while WASPAS is better suited for adaptive or personalized recommendation contexts.

Abstract

Diabetes is one of the most common diseases people suffer from today, and it can lead to complications such as blindness, heart disease, and kidney failure. The condition of blindness caused by this disease is known as diabetic retinopathy (DR). An ophthalmologist will use a fundus camera to examine the retina, looking for several clinical features, such as microaneurysms (MA), hemorrhages (HM), cotton-wool spots (CWS), and exudates. Based on these clinical symptoms, clinicians then determined the patient's level of diabetic macular edema (DME) severity. Although several studies have applied CNN-based architectures for diabetic retinopathy detection, limited attention has been given to the impact of dataset imbalance handling on DME severity classification, particularly using ResNet-50. This study highlights the significant impact of extensive data augmentation on classification performance in imbalanced DME datasets. Evaluate performance using the accuracy, precision, and recall metrics. We used the IDRiD dataset, which consists of 516 images split into a training set of 413 and a test set of 103. IDRiD divides the dataset into three classes, namely normal, moderate DME, and severe DME. In the preprocessing stage, we enhanced contrast using CLAHE and resized the images to 224x224 pixels. To address the imbalance, we applied 11 data augmentation methods. We experimented by comparing the performance of two models: one with and one without dataset augmentation. Based on the test results, the best performance was obtained with the model that included dataset augmentation, achieving an accuracy of 0.5961, a precision of 0.63, and a recall of 0.61, while the baseline model (without dataset augmentation) gained 0.4553, 0.36, and 0.34 for the accuracy, precision, and recall, respectively.
