Abstract

With the rise of the Internet, e-commerce platforms have become one of the primary shopping channels for consumers. Establishing an efficient and intelligent customer service system is a crucial challenge for these platforms. This research aims to analyze how the interactivity of e-commerce applications and customer feedback from online shopping experiences can influence consumer loyalty and the likelihood of repurchase. To evaluate customer loyalty, we utilize an artificial neural network, which is processed using the SPSS application. The findings indicate that the relationship between interactivity, consumer feedback, and loyalty has a confidence level of 85.4%. A relationship between variables is considered strong if the R-squared value is above 50%, while a value below 50% indicates a weaker relationship.

Abstract

Dalam lanskap bisnis yang semakin cepat dan kompetitif, teknologi sangat diperlukan untuk mengoptimalkan dan menyederhanakan operasi bisnis. Dampak Pemberian Reward dan Herd Mentality Terhadap Kinerja Berbasis Teknologi Karyawan Depo Kontainer di Jakarta Utara adalah penelitian yang bertujuan mengonfirmasi pentingnya reward dan herd mentality bagi aspek bisnis di perusahaan. Penelitian ini menyelidiki pengembangan kapabilitas kinerja karyawan informasi sebagai mekanisme penting dalam peningkatan efektivitas dan efisiensi organisasi. Kedua hal tersebut dianggap vital sebagai sumber daya utama perusahaan dalam menghadapi tantangan perubahan teknologi. Penelitian ini dilakukan dengan metode kuantitatif yaitu pengujian berbagai hipotesis yang dibangun dari model penelitian yang diusulkan menggunakan data melalui survei kuesioner. Validitas alat ukur dinyatakan valid, dan reliabilitas dengan hasil reliabel. Pengolahan data dilakukan dengan SPSS Versi 25 untuk melihat signifikansi hubungan-hubungan dalam model penelitian yang diobservasi.

Abstract

Penelitian ini bertujuan untuk menguji dan menganalisis pengaruh beberapa faktor yang terkandung dalam Technology Acceptance Model (TAM), yaitu Perceived Usefulness (PU), Perceived Ease of Use (PEOU), serta sikap pengguna, terhadap niat penggunaan aplikasi e-commerce. Model ini sering digunakan untuk memahami bagaimana dan mengapa individu menerima atau menolak teknologi baru, yang dalam hal ini adalah aplikasi e-commerce. Penelitian ini tidak hanya menilai pengaruh faktor-faktor tersebut secara terpisah, tetapi juga menganalisis hubungan antar konstruk yang ada dalam model TAM. Untuk mencapai tujuan tersebut, pengujian dilakukan dengan menggunakan Confirmatory Factor Analysis (CFA) untuk menguji validitas dan reliabilitas instrumen pengukuran yang digunakan dalam penelitian ini. CFA adalah teknik statistik yang digunakan untuk mengonfirmasi sejauh mana data yang dikumpulkan sesuai dengan model teori yang telah ditentukan sebelumnya. Selain itu, Structural Equation Modeling (SEM) digunakan untuk menganalisis hubungan antar konstruk dalam model, serta untuk menguji sejauh mana faktor-faktor tersebut mempengaruhi niat pengguna untuk menggunakan aplikasi e-commerce. Data dalam penelitian ini bersumber dari kuesioner 103 pengguna aplikasi e-commerce yang tinggal di kota Bekasi. Kuesioner dirancang untuk mengukur persepsi dan sikap pengguna terhadap aplikasi e-commerce, baik dari segi kemudahan penggunaan (PEOU) maupun manfaat yang dirasakan (PU). Hasil analisis menunjukkan bahwa kedua faktor, yaitu PU dan PEOU, berpengaruh signifikan terhadap sikap pengguna (attitude) dan niat (intention) mereka untuk menggunakan aplikasi e-commerce. Selain itu, penelitian ini juga menemukan adanya pengaruh langsung antara Perceived Usefulness dan Perceived Ease of Use terhadap niat penggunaan aplikasi tersebut, yang semakin menegaskan pentingnya kedua faktor ini dalam meningkatkan adopsi aplikasi e-commerce.

Abstract

This study discusses the integration of Convolutional Neural Network (CNN) and K-Nearest Neighbors (KNN) for the identification of coffee bean quality as an effort to increase the competitiveness of local commodities. CNN is used as a feature extractor to produce an information-rich representation of coffee bean images, while KNN acts as a classifier to classify quality into two classes, namely Good and Defective. The dataset is divided into training, validation, and test data, with a total of 1,190 images obtained from the manual annotation process. The research stages include (1) pre-processing of data in the form of cropping based on bounding boxes, resize to 224×224 pixels, normalization, and data augmentation; (2) feature extraction using pretrained CNN (ResNet18) by eliminating the final classification layer to obtain a 512-dimensional feature vector; and (3) classification using KNN with variations in k values (3, 5, and 7) as well as Euclidean distance metrics. The results of the experiment showed that the CNN+Softmax baseline resulted in an accuracy of 86%, while the CNN+KNN method provided better performance. The k=5 configuration was proven to be optimal with an accuracy of 93.4%, precision, recall, and a balanced F1-score in both classes. The confusion matrix shows that most samples can be classified correctly with a low error rate. These findings are in line with previous research that emphasized the effectiveness of CNN in the extraction of visual features and the advantages of KNN on limited datasets. Thus, this approach can be a practical solution to support an automatic, accurate, and consistent coffee bean quality identification system to increase the competitiveness of local coffee commodities in the global market.
