Abstract

This study aims to solve the problem of grouping books that are most often borrowed at the library and provide priority recommendations for procuring the right books. Currently the priority for procuring books at the Sekolah Tinggi Akuntansi dan Manajemen Indonesia (STAMI) Library is still done manually. To overcome this problem, two methods are used, namely the K-Means method which functions to group books based on the number of book titles and the ELECTRE method which is used to prioritize books to be purchased. The decision support system built using the ELECTRE method utilizes criteria consisting of the number of books borrowed, copies, book prices, and majors. The results of this study are a web-based decision support system consisting of 11 alternatives grouped, namely: Buku-013, Buku-063, Buku-072, Buku-074, Buku-075, Buku-076, Buku-084, Buku - 092, Book-102, Book-122, and Book-125. With this Decision Support System, the Library of the Indonesian College of Accounting and Management can easily prioritize procuring books in the library.

Abstract

Pengabdian Kepada Masyarakat (PKM) yang dilakukan di Desa Pardamean Sibisa dalam hal pengolahan pasca panen kopi organik yang belum dikelola secara optimal. Penanaman kopi arabika di kecamatan Ajibata sekitar 250 ha dan kopi arabika organik di Desa Pardamean Sibisa mencapai 30 ha. Tujuan pengolahan kopi organik setelah panen adalah untuk meningkatkan nilai tambah produk dari olahan biji kopi organik menjadi kopi bubuk berkualitas baik. Pengolahan hasil panen yang dilakukan oleh masyarakat selama ini hanya sebatas kopi biji atau gabah yang dijual langsung kepada agen pengumpul. Dengan adanya pengolahan biji kopi organik menjadi bubuk kopi organik akan meningkatkan nilai jual yang diproduksi dari lahan petani sendiri yang merupakan kawasan wisata Danau Toba. Pengolahan pasca panen kopi organik yang akan dilaksanakan di desa Pardamean Sibisa merupakan proses perlakuan fermentasi, pengeringan, sangrai, penggilingan dan pengemasan. 80 % peserta workshop mendapatkan pemahaman baru dalam pengolahan dan strategi pemasaran. Kegiatan PKM ini memberikan manfaat bagi masyarakat Desa Pardamean Sibisa untuk meningkatkan pendapatan masyarakat.

Abstract

Research on digital literacy in MSMEs has gained attention; however, its intersection with women’s entrepreneurship and cultural heritage in sustainable tourism remains underexplored. This study seeks to fill this gap by examining how digital literacy and local wisdom jointly influence the sustainability of women-led MSMEs in Lake Toba, Indonesia, a UNESCO Global Geopark. A qualitative approach was applied through in-depth interviews with 50 women entrepreneurs engaged in culinary, handicraft, homestay, and creative sectors, along with officials from the Cooperative and the MSME Office of Samosir Regency. The data were analyzed using thematic coding to uncover patterns of opportunities, constraints, and resilience strategies. The study reveals that women entrepreneurs serve as both economic actors and cultural custodians yet face significant challenges, including low digital literacy, limited financing access, seasonal dependency, and domestic burdens. Despite these barriers, the findings highlight a novel synergy between digital literacy and local wisdom that fosters value creation, eco-friendly innovation, and cultural-based brand storytelling as pathways to sustainability. As this was a single-case qualitative study, the results were context-specific and may not be broadly generalizable. Theoretically, this study integrates digital literacy and cultural heritage into the MSME sustainability discourse. Practically, it provides policy recommendations and training models to promote women’s empowerment and sustainable rural tourism.

Abstract

This community service project, titled International Collaboration in Business English Learning: Enhancing Global Communication Skills of Polytechnic Students, was conducted by Doris Yolanda Saragih, S.Pd., M.Pd., in collaboration with Pauline De Goeje (Leiden University) and Mart Vogel (Utrecht University). The activity took place at Politeknik Bisnis Indonesia on September 30, 2025, involving 60 students across two interactive sessions. The main objective was to strengthen students’ Business English competence and cross-cultural communication skills in preparation for participation in global business environments. A production-oriented and communicative approach was applied through case discussions, role-play simulations, and digital-based learning to enhance students’ speaking, writing, and negotiation proficiency. The international collaboration component enriched the experience by providing authentic exposure to professional business contexts and global cultural perspectives. The findings revealed that students showed notable improvement in confidence, vocabulary mastery, and motivation to use English for professional communication. Furthermore, the project contributed to developing employability and intercultural awareness, supporting the institution’s mission to produce globally competitive graduates. Overall, this community service initiative demonstrated that sustainable collaboration with international experts can significantly enhance Business English learning outcomes and prepare students to communicate effectively in global business settings.
