Abstract

Lapis tipis aspal pasir (Latasir) merupakan campuran aspal panas sebagai lapis permukaan jalan yang banyak menggunakan pasir, kebutuhan akan material pasir juga meningkat dengan adanya pembangunan prasarana jalan yang semakin pesat. Material yang baik akan mempengaruhi kualitas jalan, penggunaan pasir bekas tambang emas yang ada di desa Hampalit dapat meningkatkan nilai karakteristik Marshall dan dapat memperoleh fleksibilitas pada campuran Latasir. Metode yang digunakan dalam penelitian ini menggunakan metode uji Marshall dengan membuat variasi kadar aspal, Penelitian ini bertujuan untuk membandingkan pasir bekas tambang emas didua titik pegambilan disatu desa yaitu Lokasi 1 (STA 7+300) dan Lokasi 2 (STA 8+700). Berdasarkan hasil pemeriksaan Sifat-sifat fisik agregat dilaboratorium untuk Lokasi 1 (STA 7+300) pada saringan No.200 lolos sebanyak 4,24% sedangkan umtuk Lokasi 2 (STA 8+700) pada saringan No.200 lolos sebanyak 8,04%. Kemudian didapat nilai variasi kadar aspal masing-masing komposisi. Untuk komposisi I (STA 7+300) dengan variasi kadar aspal yaitu 6%, 6,5%, 7%, 7,5%, 8% dan untuk komposisi II (STA 8+700) dengan variasi kadar aspal yaitu 6,5%, 7%, 7,5%, 8%, 8,5%. Sehingga masing-masing komposisi campuran menggunakan pasir bekas tambang emas semua Parameter Marshall memenuhi spesifikasi yang disyaratkan oleh Bina Marga tahun 2018 (revisi 2) dimana kedua komposisi tersebut memiliki karakteristik yang berbeda, yaitu didapat nilai Kadar Aspal Optimum (KAO) Kompsoisi I (STA 7+300) sebesar 7,93% dan Kadar Aspal Optimum (KAO) komposisi II (STA 8+700) sebesar 8,20%.

Abstract

Transportation is one of the essential means of human needs. In this modern era and with the increasing population density in urban areas, transportation is highly necessary to meet an individual's needs in carrying out activities or moving from one place to another, whether it be short distances or long distances. Transportation is the lifeline of national development in facilitating the flow of people, goods, and information as a support for the optimal allocation of economic resources. Therefore, transportation services must be adequately available, evenly distributed, and affordable to the purchasing power of the society. Data on the components of vehicle operational costs were obtained through an interview with the manager of PO. Logos buses, and then the data were analyzed using the Pacific Consultants International (PCI) method, and the amount of vehicle operating costs incurred by PO. Logos. To determine the Ability To Pay (ATP) and Willingness To Pay (WTP) values, the required data is obtained through the distribution of a questionnaire via Google Form, which is filled out by passengers of the PO. Logos bus company. The data analysis results indicate that the operational cost of the vehicle is 15,065.6753/km and the fare based on the Cost of Service (COS) is Rp. 106,811.133, based on the Ability To Pay (ATP) is Rp. 145,054.33, and the Willingness To Pay (WTP) value is Rp. 101,903.00. A primary survey needs to be conducted to obtain the existing load factor value for tariff calculations.
