This study aims to analyze consumer preferences for fast food restaurants in Indonesia using aspect-based sentiment and emotion analysis. The research data was obtained from Google reviews and questionnaires distributed to 100 respondents. The analysis process includes data cleaning, TF-IDF weighting, and data separation into training and testing sets. Aspect-based sentiment analysis was used to identify positive and negative sentiments on various aspects of the service, while emotion analysis was applied to measure the types and levels of customer emotions based on the detected sentiments. The visualization results show the various sentiments and emotions associated with each aspect of the restaurant's service attributes. In addition, this study used a three-dimensional Importance Performance Analysis (IPA) model to evaluate the relationship between importance and satisfaction levels based on customer sentiments and emotions.  The results of aspect-based sentiment analysis show that most restaurants get positive sentiments on all aspects. The emotion analysis results demonstrate a correlation between any positive sentiment and positive emotions, and vice versa. The findings in this study are expected to provide valuable insights for restaurant managers to improve customer experience through an in-depth understanding of customer sentiments and emotions.

Abstract

The business process improvement at the Research and Community Services Center (LPPM), at a private university in Jakarta, was initiated due to unclear Standard Operating Procedures (SOPs) and the introduction of a new operational mechanism. The main objective of this research is to analyze and map the current business processes to clarify existing workflows. The IDEF0 method is used to identify and evaluate these processes, while the overall analysis follows Business Process Improvement (BPI) principles. The focus is on three core processes: proposal submission, fund disbursement, and reporting—each essential to research, community service, and publication activities. Improvements are proposed through the development of a revised SOP and the design of an online database system. These enhancements are based on interviews with key stakeholders, including the Head of the Center for System Development, LPPM officials, and staff. The use of the IDEF0 method significantly assists in identifying the roles and responsibilities of involved parties in each process. It provides a structured approach to evaluating and refining workflows. As a result, a new database system is being designed to support better data management and documentation at LPPM. This system will be built upon the improved processes identified through the IDEF0 analysis, ensuring more efficient and transparent operations.

Abstract

Program Pengabdian kepada Masyarakat (PkM) ini berangkat dari rendahnya pemahaman masyarakat tentang manfaat tempe, meskipun tempe merupakan makanan tradisional Indonesia yang kaya gizi dan bernilai ekonomi. Sejak 2023, Fakultas Biosains, Teknologi, dan Inovasi (FBTI) serta Pusat Penelitian & Pengembangan Tempe (P3T) Unika Atma Jaya bekerja sama dengan Kampung Tempe Ciomas untuk mendorong inovasi pengolahan tempe. Tujuan utama kegiatan adalah meningkatkan pengetahuan dan keterampilan ibu-ibu WKRI (Wanita Katolik Republik Indonesia) Ranting Pangkalan Jati dalam memproduksi tempe sehat sekaligus memperluas pengenalan Kampung Tempe Ciomas agar penjualan produknya meningkat. Pelaksanaan program dilakukan melalui kolaborasi dosen dan mahasiswa dengan mitra. Workshop interaktif menjadi metode utama, di mana peserta dilibatkan langsung dalam praktik pembuatan tempe, didukung demonstrasi, diskusi, dan tanya jawab. Hasil evaluasi melalui kuesioner pre-test dan post-test menunjukkan peningkatan signifikan pemahaman peserta, meliputi mikroba fermentasi, manfaat gizi, hingga sejarah tempe. Analisis deskriptif memperkuat bahwa kegiatan ini efektif dalam menambah wawasan. Luaran program mencakup laporan, dokumentasi video yang dipublikasikan di Instagram Kampung Tempe Ciomas, serta artikel jurnal untuk mendukung keberlanjutan. Dokumentasi ini sekaligus berfungsi sebagai sarana promosi dan edukasi masyarakat. Dengan demikian, kegiatan ini diharapkan memberi dampak positif terhadap peningkatan gizi keluarga dan pendapatan masyarakat secara berkelanjutan.

Abstract

Penelitian ini bertujuan untuk mengevaluasi tingkat kesesuaian antara ekspektasi pelanggan dengan persepsi mereka terhadap kualitas layanan yang diberikan oleh minimarket, dengan menggunakan pendekatan Importance Performance Analysis (IPA). Fokus utama dari studi ini adalah untuk mengidentifikasi atribut-atribut layanan yang memerlukan peningkatan kualitas serta atribut yang kinerjanya sudah sesuai dengan harapan pelanggan dan patut dipertahankan. Sebanyak 100 responden dipilih secara purposive sampling dan diminta untuk memberikan penilaian terhadap 50 atribut layanan melalui instrumen kuesioner dengan skala Likert. Data yang diperoleh kemudian dianalisis dengan menghitung Tingkat Kesesuaian Indeks (Tki) dan memetakan setiap atribut ke dalam empat kuadran dalam kerangka IPA. Hasil penelitian menunjukkan bahwa 15 dari 50 atribut layanan tergolong dalam kuadran Concentrate Here, yang menandakan bahwa atribut-atribut tersebut memiliki tingkat kepentingan tinggi namun performanya masih rendah, sehingga menjadi prioritas utama untuk diperbaiki. Di sisi lain, sebanyak 14 atribut masuk ke dalam kuadran Keep Up the Good Work, yang mencerminkan bahwa minimarket telah memberikan layanan dengan kualitas baik dan sesuai harapan pelanggan, sehingga keberlanjutannya perlu dijaga. Sisa atribut tersebar pada kuadran Low Priority dan Possible Overkill, yang mengisyaratkan adanya peluang untuk efisiensi dalam alokasi sumber daya tanpa mengorbankan kepuasan pelanggan. Berdasarkan hasil tersebut, studi ini merekomendasikan agar manajemen minimarket memfokuskan upaya perbaikan pada atribut-atribut yang dianggap penting namun belum memenuhi ekspektasi pelanggan, sekaligus mempertahankan kinerja atribut yang telah berjalan optimal. Diharapkan, strategi tersebut dapat berkontribusi pada peningkatan kepuasan pelanggan secara menyeluruh serta mendukung efisiensi dan efektivitas operasional perusahaan dalam jangka panjang.
