Abstract

This study aims to analyze the trip generation of students traveling to the campus of the Catholic University of Indonesia Santu Paulus Ruteng using a multiple linear regression statistical approach. Trip generation is a crucial aspect of transportation planning, especially in higher education areas with high mobility intensity. Data were collected through questionnaires distributed to 1,035 students from various study programs, determined using the Slovin formula with a 10% margin of error. This research examines respondent characteristics based on gender, mode of transportation, travel time, and the number of trips to campus per day. The results show that the most commonly used mode of transportation is motorcycles (42%), with the majority of students (63%) taking less than 15 minutes to reach campus, and 64% making only one trip per day. Regression analysis reveals that the number of classrooms and the campus land area simultaneously have a significant effect on the number of daily student trips, with an R Square value of 0.820. The t-test indicates that the number of classrooms has a significant positive effect, while the land area has a significant negative effect on trip frequency. These findings suggest that high academic activity, reflected in the number of classrooms, is the primary driver of student mobility. This study provides valuable input for data-driven campus transportation policy, which can be used to design an efficient, safe, and sustainable transportation system for the academic community.

Abstract

Abstrak Penelitian ini bertujuan mengevaluasi kelayakan material gunung quary Bondo sebagai timbunan pilihan, agregat kelas A dan agregat kelas B perkerasan lentur jalan raya. Hasil uji laboratorium menunjukkan bahwa jenis tanahnya memiliki batas cair 22%, indeks plastisitas 5%, lolos saringan Nomor 200 5,32% sampai 5,54%, Cu rata-rata 92,68 > 4, Cc rata-rata 5,17 > 3; Berdasarkan USCS dikategorikan sebagai GP-GM atau ML (low plasticity silt), kelompok A-1-a (0) menurut AASHTO. Nilai aktif sebesar 0,90 < 1,25 termasuk tanah normal. Berat isi kering maksimum 1,56 gr/cm3 pada kadar air optimum 22,9%, nilai CBR rendaman 96 jam sebesar 24% dan abrasi sebesar 22,49%, sehingga layak sebagai material timbunan pilihan perkerasan lentur jalan raya, tetapi tidak layak dipergunakan sebagai material agregat kelas B karena nilai CBR rendaman < 60% dan juga tidak layak dipergunakan sebagai agregat kelas A karena persen lolos saringan 1 ½ ˜ kurang dari 100% dan nilai CBR rendamannya < 90%. Kata kunci: laboratorium, layak, agregat, timbunan pilihan Abstract This research aims to evaluate the suitability of Mount Quary Bondo material as the embankment, class A and B aggregate for flexible pavement. Laboratory test results show this type of soil has LL of 22%, PI 5%, 5.32% to 5.54% passing No. 200 sieve, average Cu 92.68, average Cc 5.17 3; It is categorized as GP-GM or ML (USCS), and A-1-a (0) (AASHTO). The active value is 0.90 < 1.25 including normal soil; max dry density 1.56 gr/cm3 at 22.9% wopt, the soaked CBR of 96 hours is 24%, the abrasion is 22.69%; so it is suitable as the embankment for flexible highway pavement, but is not suitable for use as class B aggregate material because the soaked CBR < 60% and it is also not suitable for use as class A aggregate because percentage passing the 1 ½ (38,1 mm) sieve < 100% and the soaked CBR < 90%. Keywords: feasible, aggregate, selected material
