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

The goal of this study is to look into how work motivation, the work environment, and training affect how well employees do their jobs at PT Medcomm Solution. In service organizations, human resources are regarded as a strategic element affecting performance, with other internal organizational factors contributing. This study utilized a quantitative methodology with a causal associative research design. The sample encompassed all 60 employees, employing a census sampling methodology. The data were analyzed using multiple linear regression. The findings suggest that job motivation and training positively and significantly influence employee performance, however the work environment does not. These three independent factors have a substantial effect on employee performance at the same time, as shown by the F-value of 20.085 and the significance level of 0.000 (<0.05). The coefficient of determination value of 51.8% shows that the variables of work motivation, work environment, and training can explain differences in employee performance. The other 48.2% is due to factors not included in this research model, such as rewards, pay, work discipline, organizational culture, job satisfaction, work stress, and individual employee characteristics.

Abstract

This study aims to analyze and optimize the scheduling of a residential construction project using the CPM, crashing techniques, and the PERT. A quantitative approach is employed by utilizing data obtained from observations and interviews conducted on a housing construction project in Bandar District, Simalungun Regency. CPM analysis is used to identify the critical path and determine the project duration, while crashing techniques are applied to obtain acceleration alternatives by considering additional costs. Furthermore, the PERT method is used to analyze uncertainty in project duration and to calculate the probability of project completion. The results show that the project duration under normal conditions is 59 days, with the critical path identified as A–B–D–E–G–H–J–O–P. After applying crashing, the project duration is reduced to 55 days with an additional cost of IDR 212,500. The PERT analysis indicates that the expected project duration is 44 days, with a completion probability of approximately 99% for a target duration of 49 days. These findings demonstrate that the combination of CPM, crashing, and PERT methods is effective in improving time and cost efficiency, while also providing a more reliable basis for decision-making under conditions of uncertainty.
