Abstract

Universities play a vital role in human resource development. However, the dropout rate at many universities remains high that suffers education efficiency and effectiveness. This study examines factors that affect student retention to find a suitable approach. In this article, we compare engineering and economics students to see whether any variations in the characteristics impact student retention across these two fields. This knowledge sharpens ways to increase student retention rates. The research was conducted quantitatively using a questionnaire. Data were processed by discriminant analysis, crosstabulations, and descriptive statistical methods. The results found that different factors affect engineering and economics students’ retention. GPA and student satisfaction with close social relationships with fellow students were shown to be the determining variables for engineering students’ retention. Meanwhile, student satisfaction with lecturer feedback on course progress and student confidence to graduate on time are drivers of economics students’ retention.

Abstract

Funny's Kitchen is one of the tenants of Foodcourt E at X University. Internal improvements were carried out based on research on students as the main consumers of Funny's Kitchen. The results of Multiple Linear Regression processing from 99 students' data show that the freshness of the food, the suitability of the price to the quality of the food provided, and the correct temperature of the food provided have a significant effect on students' interest in repurchasing at Funny's Kitchen. It is proposed that Funny's Kitchen use a microwave to speed up the process of heating food, maintain the taste of the food, employ employees who can help with the process of preparing and serving food, and adjust prices to the quality of the food provided. In this PKM, training was carried out to calculate the cost of production and it was discovered that Funny's Kitchen could still increase the quantity of its food portions. It is hoped that through the improvements made, student interest in buying back traditional food at Funny's Kitchen can increase.

Abstract

Wheelchairs are necessary mobility aids for people with lower-limb disabilities. However, transporting a heavy electric wheelchair in a car presents challenges and can result in injuries to caregivers who assist with loading and unloading. The goal of this study was to create an ergonomic transfer assist that would make it easier and safer to transport wheelchairs into cars. The Avanza Hatchback and electric wheelchair were measured for width, length, base height, and weight. Using this information, a transfer assist with a slanted base was built using ergonomic principles to alleviate physical strain during loading and unloading. The design was also based on the REBA (Rapid Entire Body Assessment) score to determine the optimal posture. This study makes a unique addition because it focuses on specific aids for safe wheelchair transfers into and out of automobiles, where there is currently insufficient research.

Abstract

Permasalahan yang dialami oleh gerai-gerai di Kantin Eureka, Bandung adalah penurunan pendapatan karena gerai menjadi semakin sepi pelanggan, terutama setelah pandemi COVID-19. Penurunan pendapatan ini dapat berakibat tutupnya gerai-gerai di Kantin Eureka. Pengabdian Kepada Masyarakat (PKM) ini berusaha untuk membantu gerai-gerai untuk mempertahankan dan meningkatkan kepuasan pelanggan. Sebelum mempertahankan dan meningkatkan kepuasan pelanggan, gerai harus bisa mengukur kepuasan pelanggan, menemukan variabel yang perlu diperbaiki untuk meningkatkan kualitas layanan, dan prioritasnya. Pengukuran kepuasan pelanggan pada PKM ini dilakukan dengan mengkombinasikan konsep Service Quality (Servqual) dengan variabel-variabel bauran pemasaran. Pengukuran dapat dilakukan dengan penyebaran kuesioner kepada pelanggan. Kuesioner dibuat berdasarkan variabel-variabel yang mempengaruhi kepuasan pelanggan, yaitu variabel bauran pemasaran. Tim PKM Dosen Prodi Teknik Industri, Universitas Kristen Maranatha membantu gerai-gerai di Kantin Eureka dengan membuatkan alat ukur dengan variabel yang sesuai. Setelah itu, tim memberikan pelatihan tentang kepuasan pelanggan, variabel-variabel penentu kepuasan, pembuatan alat ukur, pengolahan data, dan interpretasi hasil pengolahan data kepada pemilik/pekerja gerai-gerai di Kantin Eureka. PKM dilakukan pada bulan Mei sampai Agustus tahun 2024. Pelatihan dilakukan di ruang pertemuan PT. DSU tanggal 25 Juli 2024. Dari hasil pengukuran, didapat variabel apa saja yang dinilai tidak memuaskan oleh pelanggan.  Berikutnya pelatihan juga diberikan untuk menentukan urutan prioritas perbaikan, sehingga gerai bisa melakukan prioritas perbaikan. Dengan diberikannya pelatihan ini, diharapkan gerai-gerai dapat menjaga agar kepuasan pelanggan selalu baik, dan penjualan mereka bisa naik. Hasil dari pretest dan posttest, yaitu dilakukan sebelum dan sesudah pelatihan, menunjukkan bahwa pelatihan efektif, dibuktikan dengan berbedanya hasil nilai rata-rata pretest dan posttest.
