Marka yellow box junction (YBJ) adalah marka kotak kuning dengan dua garis diagonal berpotongan yang berfungsi untuk melarang kendaraan berhenti di area persimpangan agar tidak terjadi kemacetan. Namun dalam penerapannya, masih banyak pengendara melakukan pelanggaran marka YBJ sehingga gridlock sering terjadi di persimpangan, khususnya di kota besar seperti Surabaya. Untuk itu dilakukan penelitian untuk mengetahui keefektivitasan marka YBJ terhadap kinerja simpang, hubungan keberadaan marka YBJ terhadap keefektivitasan kinerja simpang, kesesuaian standar YBJ, dan pengetahuan pengendara terhadap marka YBJ di Surabaya. Simpang Jl. Margomulyo - Jl. Tandes Lor dianggap dapat menjadi parameter untuk kinerja simpang, dan tingkat pelanggaran marka YBJ. Dilakukan juga pengecekan kesesuaian standar pembagian kuisioner tingkat pengetahuan pengendara di Surabaya terhadap YBJ, dengan menggunakan metode analisis koefisien korelasi dengan bantuan software SPSS 26. Dari hasil keefektivitasanYBJ terhadap kinerja simpang, diperoleh hasil tidak efektif dengan angka tundaan sebesar 45.72 det/skr, dan tingkat pelayanan simpang E. Dari analisa hubungan, diperoleh hubungan yang erat antara keberadaan YBJ dengan kinerja simpang. Dari hasil survei kesesuaianYBJ dengan peraturan, diperoleh adanya ketidak sesuaian dimensi dengan peraturan yang berlaku, sehingga kesesuaian YBJ adalah tidak efektf. Dari hasil survei tingkat pengetahuan YBJ diperoleh tingkat pengetahuan pengendara terhadap definisi, dan fungsi YBJ adalah cukup baik, akan tetapi banyak pengendara masih belum mengetahui sanksi pelanggaran YBJ karena sangat kurangnya sosialisasi dari Pemerintah Surabaya.

The plan to develop a cable car/gondola on Tambak Wedi Road in Surabaya has triggered trip generationand attractions, which can eventually decrease the performance of this road. Therefore, an analysis of the road performance due to the development of the cable car/gondola is necessary to minimize the impact of its performance and to provide solutions to traffic problems when the analysis indicates bad results. This research employed the method of the Manual Kapasitas Jalan Indonesia (MKJI 1997), or Indonesian Highway Capacity manual, and other related regulations. The analysis of road performance began with a traffic survey and was followed by predicting trip generation and attraction. After analyzing the existing conditions of road performance, the researcher analyzed the traffic predictions during construction and operation as well as proposed recommendations for alternative management to overcome the traffic impacts caused by the planned development. The research results demonstrated that the existing condition on Tambak Wedi Road obtained the highest result in the morning by V/C Ratio 0.16 and LOS A, whereas during the construction, the highest result occurred in the morning by V/C Ratio 0.2 and LOS A. Finally, during the operation, the highest result also occurred in the morning by V/C Ratio of 0.57 and LOS A.

Juanda Airport as one of airports in Indonesia has served domestic and international flight. Airports are usually located in outlying areas accessible via direct access freeways or transit lines rather than at the center of metropolitan areas restricted by local grid networks, so their market area can be measured. The modes used at Juanda airport are dominated by private vehicles and cab. And it caused a lot of queue in the drop zone area at the peak hour and also needed some additional parking area which has overloaded in capacity. Information on the use of transportation modes is very important to know. This needs sould important in order to maximize the need for facilities related to the use of access modes to the airport. The method used is to identify the use of vehicles that access the airport, evaluate the performance of parking lots, evaluate of pick up and drop off area, evaluate the number of queues at the drop off and pick up area and when if mass transportation is held to provide access modes to the airport. The result shows that private vehicles dominate as vehicles accessing the airport by 87,78% and public vehicles by 12,23%. Peak hours of vehicles arrival at 9 AM. The analysis of the use of the drop off area a queue of vehicles by 87,57% and demand in the parking lots of 60,37%. From the proposal of using mass transportation to reduce queue in the drop zone area by 12,42% and reduction in parking lots demand by 39,62%.

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 persen. Dari data Marshall Test yang didapatkan, memenuhi persyaratan sesuai Spesifikasi Bina Marga 2010 adalah serbuk arang kayu yang berkadar 10 persen. Pada benda uji serbuk arang kayu 10 persen dihasilkan VIM sebesar 5,32 persen, 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 persen meningkatkan nilai Marshall Test.
