Abstract

The construction of the Probolinggo-Pasuruan toll road has resulted in faster travel times along the Jember-Surabaya route. However, it has been observed that economy buses rarely use the toll road. To determine the likelihood of passengers switching between economy-class train and economy-class bus modes, a study on the selection of economy-seat modes between the cities of Jember and Surabaya is necessary. The study utilized the Stated Preference method for data collection, which involved distributing questionnaires to passengers at stations and terminals. The data collected were analyzed using the binomial difference method. The results of the study reveal that the Economy-Class Train mode is the most preferred mode of transportation. Experimentation on the travel cost attribute (ΔX1) with the value of Uka-Ubu Utility = 6.512 - 0.0887(X1) + 0.292(X2) revealed that 99% of passengers chose the train. On the travel cost attribute (ΔX1) with the value of Uka-Ubu Utility = 0.0205 - 0.0034 X1, 55.2% of passengers chose the train. Meanwhile, on the travel time attribute (ΔX2) with the value of Uka-Ubu Utility = 0.0202 - 0.0034 X2, 52.6% of passengers chose the train.

Abstract

Penggunaan bahan bangunan berbasis fosil yang terus-menerus cenderung merusak dan mencemari lingkungan. Penggunaan bahan terbarukan dan berkelanjutan sangat penting dilakukan. Bambu merupakan bahan terbarukan, berkelanjutan, murah, dan berwawasan lingkungan. Dua tujuan penelitian ini adalah (1) menarik minat masyarakat untuk menggunakan bahan bangunan berbasis lingkungan, dan (2) menganalisis kelayakan dan potensi bambu untuk digunakan sebagai tulangan elemen struktur pelat pondasi. Empat specimen pondasi dengan dimensi 70 x 70 x 15 cm3 yang terdiri dari tiga pelat pondasi beton bertulang bambu (PDB) dan satu pelat pondasi beton bertulang baja (PDS). Dimensi tulangan bambu 15 x15 mm2 dan diameter tulangan baja 10 mm. Variasi jarak tulangan bambu sebesar 100 mm, 125 mm, dan 150 mm. Jarak tulangan baja sebesar 130 mm. Pondasi diuji dengan beban terpusat pada titik tengahnya. Hasil penelitian menunjukkan pondasi PDB dengan jarak tulangan 100 mm mempunyai kapasitas lebih tinggi 3.16% dari pelat pondasi PDS dengan diameter tulangan 10 mm dengan jarak 13 mm. Pelat pondasi PDB mempunyai kesamaan pola keruntuhan dengan pondasi PDS sebagai pondasi kontrol. Pondasi PDB layak diusulkan untuk pondasi rumah-rumah sederhana pedesaan yang banyak bambu.

Abstract

A landslide on a retaining wall in the Ki Ronggo Bridge area, Bondowoso Regency, requires a reinforcement evaluation to maintain slope stability and the safety of the surrounding infrastructure. This study aims to compare the performance of sheet piles with and without anchors using secondary data from soil investigations, including the Standard Penetration Test (SPT). The analysis was conducted using GEO5 software to examine slope stability, bearing capacity, passive earth pressure, internal forces, anchor capacity, and structural deformation. The analysis results show that both configurations have a global slope stability safety factor of 2.73, exceeding the minimum limit of 1.50. In the configuration without anchors, the maximum bending moment reached 558.55 kN·m/m and the maximum deformation was 77.4 mm. Meanwhile, the configuration with anchors produced a maximum bending moment of 212.26 kN·m/m and a maximum deformation of 77.4 mm. The internal stability safety factor of the anchors reached 2.10, but the anchor capacity utilization rate of 99.78% indicates limited reserve capacity. These results confirm that the selection of a reinforcement system must consider geotechnical stability, structural capacity, deformation, and the adequacy of anchor capacity.
