Abstract

Congregation data collection at GPID Eben Haezer is still done manually. This causes a lot of congregation data to be unsynchronized between the written data and the actual data. In addition, it also results in inefficient administrative services to the congregation. The vision of church digitalization also raises its own problems for the church, namely the unpreparedness of the church's human resources (HR) in digital capabilities. This Community Service (PkM) activity is to help and facilitate GPID Eben Haezer in implementing congregation data management applications and mentoring training in the process of adopting technology in church governance. The training activity was attended by 7 church admins and was carried out after the stages of formulating partner needs, adjusting and implementing the application. After the training, the application usability was measured using the System Usability Scale (SUS) and a score of 83 was obtained, indicating that the implemented application was EXCELLENT and ACCEPTABLE.  Keywords: Congregation Data Collection Application; Digital Skills; Training; System Usability Scale

Abstract

The digitalization of the mobile ticketing sector in Indonesia has seen significant growth, with a projected 50% increase in mobile ticketing app usage by 2025. Popular applications such as Traveloka, Tiket.com, Agoda, and Booking.com dominate the market, yet they face several technical challenges, including navigation difficulties, unclear interfaces, performance bugs during peak hours, slow application response times, and limited features. This study employed the User Experience Questionnaire (UEQ) method and involved 578 respondents selected through purposive sampling. The criteria included active users of one of the mobile ticketing apps and individuals aged between 20 and 40 years. The results of the t-test revealed that Agoda needs to improve the perspicuity aspect by simplifying its dense user interface, particularly in accommodation and travel ticket searches. Regarding efficiency, Traveloka, Agoda, and Booking.com must enhance their search systems and address bugs/errors that disrupt performance during peak usage times. For stimulation, Traveloka should enhance user experience by providing a more dynamic and responsive layout when navigating pages or performing searches. In terms of novelty, both Agoda and Booking.com are advised to integrate local e-wallets such as GoPay, OVO, and DANA, as well as bank transfer options, since currently they only support credit card payments. These findings highlight the critical role of UX in improving user satisfaction and suggest that continuous user-centered development is essential for maintaining competitiveness in the mobile ticketing industry.

Abstract

The number of universities in Indonesia continues to grow. This condition certainly makes the flow of new student admissions increasingly competitive between universities, thus encouraging universities to do branding, show quality, and do the right positioning. Therefore, it is important for universities to adopt a data-driven approach that can provide in-depth insights into prospective students and the effectiveness of marketing strategies. The purpose of this study is to design and build an ETL (Extract, Transform, Load) pipeline to collect, process, and analyze prospective student data as part of the business intelligence (BI) system to be built. The proposed ETL architecture design supports automated microservices-based data transformation in data cleaning, normalization, and integration. In addition, it can also be used as a solution to increase the scalability and flexibility of data mobilization in the BI system. This study introduces a novel approach by designing an ETL pipeline within a business intelligence framework aimed at enhancing university marketing efforts. Unlike prior research, which has primarily applied business intelligence tools to evaluate academic activities within learning management systems, this work shifts the focus to marketing analytics. Additionally, while existing studies on higher education marketing often center around digital marketing techniques and the marketing mix, this research fills a gap by proposing a technical infrastructure that supports data-driven marketing through automated ETL processes. The resulting ETL was tested using several methods, namely Source to Target Count Testing, Source to Target Data Testing, Duplicate Data Check Testing, and Data Transformation Testing. The results of each test are valid

Abstract

Informasi Tekstual menjadi salah satu cara untuk deteksi emosi. Namun, ekstraksi emosi menjadi tantangan tersendiri dikarenakan makna implisit dan eksplisit yang terkandung dalam teks. Pendekatan Ekstraksi makna emosi berbasis teks sudah banyak dilakukan dengan model deep learning. Meski begitu, performa komputasi dan akurasi model sering kali kontradiktif dikarenakan model yang kompleks. Oleh karena itu, dilakukan eksperimental model deep learning menggunakan BERT Model Language untuk deteksi emosi. Tujuan penelitian ini yaitu menghasilkan model deteksi emosi yang optimal dan akurat yang dapat memberikan performa komputasi yang rendah. Metode yang digunakan pada penelitian ini yaitu data collection, data pre-processing, arsitektur BERT, BERT Model Comparison, dan Model Evaluation. Model deteksi emosi terbaik ditemukan pada model DistilBERT dengan akurasi 0.9425 dan nilai F1 0.942. Berdasarkan evaluasi proses pembelajaran model DistilBERT, terdapat loss trend menurun sehingga model semakin mampu untuk melakukan prediksi emosi yang baik terhadap unseen data. Model deteksi emosi yang diusulkan, menghasilkan performa lebih unggul dibandingkan dengan model deteksi emosi menggunakan deep learning pada penelitian sebelumnya dimana model ini dapat meminimalisir kompleksitas model deteksi emosi, mengurangi komputasi namun tetap memberikan performa yang optimal.

Abstract

Saat ini, interaksi melalui platform teks marak dilakukan seperti media sosial, layanan pelanggan daring, dan forum diskusi. Oleh karena itu analisis Text Emotion Recognition (TER) menjadi sangat krusial. Namun, emosi dalam teks bersifat kompleks, kontekstual, dan sering kali bersifat implisit, sehingga tidak dapat dengan mudah diidentifikasi menggunakan pendekatan konvensional. TER merupakan proses identifikasi dan klasifikasi emosi dalam teks secara otomatis menggunakan teknik machine learning. Penelitian ini bertujuan untuk merancang model pengklasifikasian emosi berbasis teks menggunakan berbagai algoritma classification machine learning. Data teks dikategorikan ke dalam enam emosi utama: sadness, joy, love, anger, fear, dan surprise. Tahapan preprocessing meliputi tokenisasi, stop word removal, dan lemmatization, sedangkan fitur teks direpresentasikan dalam bentuk numerik menggunakan Term Frequency-Inverse Document Frequency (TF-IDF). Lima algoritma machine learning, yaitu Support Vector Machine (SVM), K-Nearest Neighbor (KNN), Random Forest, Logistic Regression, dan Multinomial Naïve Bayes, digunakan dalam pelatihan dan evaluasi model. Hasil penelitian menunjukkan bahwa model SVM dan Random Forest memberikan performa terbaik dengan akurasi mencapai 85% pada data uji. Dengan demikian, pendekatan machine learning, khususnya SVM dan Random Forest, terbukti efektif dalam klasifikasi teks emosi dan dapat diterapkan dalam berbagai aplikasi analisis sentimen. Model TER hasil eksperimental akan dilanjutkan untuk diimplementasikan pada aplikasi penanganan psikologis korban kekerasan berbasis gender (KBG) yang telah dibangun pada penelitian sebelumnya.

Abstract

Dalam usaha kuliner, analisis menu perlu dilakukan untuk melihat keseimbangan antara food cost, harga menu, popularitas item, juga pertimbangan finansial dan pemasaran. Menu engineering merupakan metodologi untuk mengelompokkan menu berdasar pada margin kontribusi dan popularitas. Pada penelitian ini dilakukan analisis menu engineering pada suatu Usaha Mikro Kecil dan Menengah (UMKM) di Kota Salatiga yang bergerak di bidang kuliner menggunakan Two-Step Cluster yang dapat menggali cluster alami sesuai dengan kumpulan data menu yang ada sehingga akan ditemukan jumlah cluster yang optimal. Two-Step Cluster adalah metode yang dapat menangani variabel kategori dan kontinu, oleh karena itu dilakukanlah adaptasi model menu engineering yang diusulkan Kasavana dan Smith (1982) dengan menambahkan variabel category, sehingga dengan menggunakan Two-Step Cluster dapat dilihat mayoritas kategori menu yang menjadi anggota pada setiap cluster. Adaptasi juga dilakukan dalam kelompok variabel kontinu, yaitu dengan menambahkan variabel revenue yang digunakan untuk perbandingan pada hasil cluster. Dengan indikator Schwarz's Bayesian Information Criterion (BIC) dihasilkanlah jumlah cluster optimal yaitu 4 cluster dengan anggota paling sedikit pada cluster “popularitas tinggi dan mempunyai margin kontribusi yang berada di atas rata-rata”. Pengujian clustering dilakukan dengan menggunakan metode Silhoutte dan menunjukkan kualitas cluster yang dihasilkan memiliki nilai Silhoutte yang besar yaitu 0,7. Hal ini membuktikan cluster-cluster yang terbentuk telah terklasterisasi dengan baik. Adapun manfaat dari penelitian ini adalah didapatkannya rekomendasi kebijakan baru untuk setiap cluster yang dihasilkan sehingga dapat digunakan  pemilik UMKM dalam upaya peningkatan revenue usaha. AbstractIn culinary business, menu analysis is needed to see the balance of food cost, menu item prices, item popularity, as well as the financial and marketing considerations. Menu engineering is a method to group menu according to the contribution margin and popularity. The present study conducts a menu analysis to a Small Medium Enterprise (SME) in culinary business in Salatiga by implementing Two-Step Cluster analysis. It aims to find the natural clusters based on the existing menu data set to discover the optimal cluster number. Two-Step Cluster is a method that can be used to process categorical and continuous variables. In this study, the menu engineering model by Kasavana and Smith (1982) was adapted by adding the categorical variable. Therefore, by using the Two-Step Cluster method, the majority of menu category in each cluster can be seen. This adaption was also implemented in the continuous variable group by adding the revenue variable used for the comparison of the cluster results. With Schwarz's Bayesian Information Criterion (BIC) indicator, the results of the study show there are four clusters, in which “the highest popularity and the contribution margin above the average” cluster has the least members. Using Silhouette method, clustering testing was conducted, indicating the cluster quality result with 0,7 Silhouette value. As for the benefit of the study, new strategic recommendations can be generated for the resulted clusters based on which SME owners can improve their revenue.
