Abstract

Jenis lapis perkerasan aspal yang sifatnya struktural dan umum dipakai di Indonesia adalah Lapis Aspal Beton (Laston) dengan lapis aus atau lapis permukaan (Wearing Course). Lapisan tersebut merupakan lapisan yang paling rentan dengan kerusakan yang diakibatkan oleh repitisi beban kendaraan dan cuaca. Penelitian ini mecoba serbuk arang kayu dapat dimanfaatkan sebagai filler dalam campuran aspal sebagai alternatif pengganti semen. Dalam penelitian ini pembuatan benda uji mengacu pada Spesifikasi Bina Marga 2010 (Divisi VI). Digunakan variasi serbuk arang kayu 10%. Dari data Marshall Test yang didapatkan, memenuhi persyaratan sesuai Spesifikasi Bina Marga 2010 adalah serbuk arang kayu yang berkadar 10%. Pada benda uji serbuk arang kayu 10% dihasilkan VIM sebesar 5,32 %, VMA sebesar 17,81, Void Filled sebesar 70,18, stabilitas sebesar 1354, Flow sebesar 3,17, Marshall Quetiont sebesar 427,5, tebal selimut aspal sebesar 8,020. Sehingga dapat di simpulkan bahwa kandungan variasi serbuk arang kayu 10% meningkatkan nilai Marshall Test.

Abstract

KAI DAOP VIII Ltd operates the commuter train for Surabaya-Bangil route to overcome the needs of people that use train to work. This train is expected to reduce the congestion in Surabaya since there are also citizen outside the city that use it for work. Thus, the performance of train operation must be evaluated such as; travel, stopping, and delay time, convenience of sitting and standing sites, and loading factor. Field survey data were collected and processed by hypothetical test 1- Sample t test. The travel time for Surabaya-Bangil was changed from 66 to 63 minutes based on the schedule while the viceversa route changed from 66 to 55 minutes. The stopping time for Surabaya-Bangil was changed from 43 to 47 minutes based on the schedule while the viceversa route changed from 43 to 50 minutes. The delay time for Surabaya-Bangil had 6 minutes and departure 4 minutes, while for Bangil-Surabaya had the arrival 7 minutes and departure 9 minutes. Those results were under the process of acceptance after the hypothetical test 1-Sample t test is done. The convenience of seat gained 0.3 m2/space in the normal condition and 0.167-0.169 m2/space during COVID-19. Meanwhile, the convenience of standing site obtained 0.25-0.29 m2/space. The loading factor got 36% for Surabaya-Bangil and 29% for Bangil-Surabaya. These results categorized as ineligible for loading factor 70% since this survey was conducted during COVID-19 pandemic.
