Abstract

To better serve its customers and make financial transactions easier, BNI Bank developed Wondr by BNI, a type of digital innovation in the banking industry. Users may access and download the Wondr by BNI application via the App Store for iOS devices and the Google Play Store for Android devices. To gauge the app's usefulness, reviews are required, and reviews can greatly impact the app's future updates. Consequently, the purpose of this research is to ascertain, by sentiment analysis, if reviews of the Wonder by BNI application are favorable or negative. The data used for this study came from the Google Play Store, and it was labeled using Microsoft Excel to get the positive and negative review counts. Then, it was processed with Data Preprocessing, and then weighting was done with TF-IDF to get the word counts. The data was then classified using the Naïve Bayes algorithm, and finally, it was evaluated to find out how accurate the results were. The dates of this study's execution are September 23, 2024, and January 10, 2025. Based on the data, Naïve Bayes produced rather accurate predictions, with a recall of 86.55%, a precision of 80.85%, and an accuracy rating of 83.03%. Because of its strong recall, the model was successful in identifying a small number of genuine positive cases.

Abstract

Perkembangan teknologi semakin maju dengan pesat, hingga terciptanya sebuah smartphone yang didalamnya tersedia berbagai fitur-fitur canggih. Play Store merupakan layanan yang dibuat oleh Google untuk pengunduhan berbagai aplikasi, game, buku digital, film secara gratis maupun berbayar. Salah satu aplikasi yang tersedia pada Play Store adalah DeepL Translate, yang merupakan aplikasi yang bisa menerjemahkan berbagai bahasa dengan menerapkan Artificial Intelegent (AI) didalamnya. Tujuan penelitian ini yaitu untuk mengevaluasi aplikasi DeepL Translate melalui analisis sentimen pada ulasan menggunakan algoritma Naïve Bayes untuk mengetahui seberapa puas pengguna dalam menggunakan aplikasi ini. Pengambilan data ulasan dilakukan menggunakan teknik scrapping dengan Google Colab sebanyak 995 data, kemudian jumlah dataset berubah menjadi 939 ulasan setelah melalui proses preprocessing dengan data positif sebanyak 771 dan 168 untuk data negatif. Dataset kemudian diseimbangkan menggunakan SMOTE dan diklasifikasikan dengan algoritma Naïve Bayes. Algoritma ini dipakai karena menggunakan probabilitas yang sederhana dan efektif dalam mengklasifikasikan sebuah data. Hasil implementasi algoritma diperoleh accuracy sebesar 93,71%, precision sebesar 98,84%, dan recall sebesar 88,85%, dengan teknik evaluasi yang digunakan adalah confussion matrix.

Abstract

This study aims to analyse the influence of Corporate Ethical Identity (CEI) on the saving interest of customers at BMT UGT Nusantara Arosbaya. The research uses a quantitative approach with a causal design. The population consists of 1,094 customers, with 66 respondents selected using purposive sampling. Data were collected through closed-ended questionnaires with a five-point Likert scale and analysed using simple linear regression. The results indicate that CEI has a significant influence on saving interest, explaining 84.7% of the variance in saving interest. This finding highlights the importance of strengthening the corporate ethical identity in building trust and customer loyalty in Islamic financial institutions. The study contributes to the development of strategies for managing customer relationships based on ethical values in Islamic financial institutions.

Abstract

Agriculture is an important sector in rural areas. However, in Karang Duwak Village, Arosbaya District, farmers still use conventional methods in the agricultural process. This results in high production costs because farming businesses mostly use farm labor, which then leads to a decrease in farmers' income. Therefore, modernization in the agricultural sector is needed to increase agricultural productivity and efficiency, involving BUMDes as a driving force in strengthening the village's potential. This research was conducted using qualitative methods through observation and interviews to obtain concrete data on the agricultural conditions in the village. Then, community service activities were carried out through the empowerment of BUMDes Karang Duwak Village in the procurement of agricultural machinery for farmers. The results of the activities showed that after using agricultural machinery, the production costs of farming businesses were reduced, the time required for the agricultural process became faster, and farmers' income increased. Farmers can increase their agricultural business capital from the profits obtained and purchase better quality rice seeds. With greater capital and better seeds, the quality of agricultural products will also improve. A good harvest will increase farmers' income and improve the economy of the village farmers. BUMDes, together with village officials and the community, worked together in the procurement and supervision of agricultural machinery use, and were responsible for maintaining the agricultural machinery so that it could be used to develop agriculture in a sustainable manner.
