Abstract

PT. ABCD merupakan perusahaan yang bergerak di bidang jasa pengangkutan dan pengolahan air limbah. Menurut manjemen perusahaan rute distribusi armada yang ada kurang optimal, sehingga menyebabkan waktu pengiriman kurang efesien, yang berdampak pula pada waktu kerja driver yang berlebih. Penelitian ini berfokus pada implementasi Nearest Neighbor (NN) dalam perencanaan pola rute armada PT ABCD dengan menggunakan metode Vehicle Routing Problem with Time Window (VRPTW), untuk pengambilan air limbah. Penelitian ini menghasilkan, terminimalisisrnya waktu tempuh, jarak tempuh, biaya distribusi, dan waktu proses dalam pengambilan air limbah oleh PT. ABCD. Dengan perbandingan antara rute awal yang sudah ada, dengan hasil perhitungan menggunakan metode VRPTW, maka didapatkan selisih hasil waktu tempuh kendaraan mencapai 1 jam 48 menit 14 detik, selisih jarak tempuh 7,1 km, selisih biaya distribusi sebesar Rp. 6.390, dan selisih waktu proses selama 2 jam 58 menit 04 detik.

Abstract

Indonesian students pursuing Arabic studies in Saudi Arabia often face a significant decline in learning motivation during their first year due to culture shock, language barriers, and academic pressure. This phenomenon represents a complex inner journey of adaptation that has not been deeply explored within the specific context of the University of Tabuk. This study aims to analyze the transformation of Arabic learning motivation among newly enrolled Indonesian students at the University of Tabuk during their first academic year. It seeks to describe the dynamic shifts in motivation and identify the internal and external factors influencing these changes. Employing a descriptive qualitative phenomenological approach, data were collected through in-depth semi-structured interviews. The data were analyzed using a phenomenological analysis model to identify significant themes regarding the participants' lived experiences. The results reveal a dynamic trajectory where motivation initially surges due to religious and academic idealism, declines caused by adaptation challenges, and eventually restabilizes through a shift toward intrinsic motivation. Key factors facilitating this resilience include a supportive academic environment, the integration of spiritual values (ibadah), social connectedness, and the utilization of technology for independent learning. This research offers novelty by identifying spiritual values as a unique primary anchor for resilience, distinguishing Indonesian students from general international students who rely mostly on academic integration. The study suggests that future research employ longitudinal approaches over the full four-year program and comparative studies across other Middle Eastern universities to validate whether the "Tabuk experience" is a regional phenomenon.
