Martapura City and Banjarbaru City are two poles of growth that are experiencing rapid development in the South Kalimantan Province. These two cities are also part of the Banjar Bakula Metropolitan Area. Rapid development, resulting in the transportation sector, has an important and strategic position. This development led to a decrease in the level of road services. The decrease in the level of road network services is indicated by, among others, a reduction in the speed of vehicle operation, congestion in areas of travel attraction. These problems cause many roads that operate with much lower capacity compared to their capacity, so it is necessary to find an optimal solution in the development of transportation infrastructure by analyzing the economical components of road infrastructure development and paying attention to the function of zones along the Jalan Jend Corridor. A. Yani Km.33 to d. Km 41. The study was conducted by analyzing the spatial plan, the existing conditions of traffic performance on the Jalan A. Yani network, Martapura City, and Banjarbaru City. Then scoring analysis of alternative transportation infrastructure development can improve the performance of Jalan A. Yani. The next stage is an economic analysis that takes into account components such as Time Value, BOK, estimated construction cost components, NPV, and BCR in order to obtain optimal transportation infrastructure development solutions. Based on the results of the study, to improve the performance of the road network on Jalan A. Yani, a solution was chosen in the form of infrastructure development of the Banjarmasin toll road (Sungai Lulut) - Martapura. As for the results of the economic analysis found, each was an NPV of - Rp. 3,406,043,000,000.00; BCR of 0.001.

Land use in the Bereng Bengkel Kelurahan, which is downstream of the Kahayan river, tends to increase, including permanent roads on the Kahayan river bank, even though these problems have an impact on the Kahayan river environment, including landslides into the river and runoff water. Therefore there is a need for research on the Kahayan river discharge. The purpose of this research is to analyze flood discharge and water level using the Snyder HSS method and water level gauge measurement tools and analyze the Kahayan river flow phenomenon. This study uses the HEC-RAS 4.1.0 program with a flow profile simulation, to calculate the profile of a fixed and non-permanent flow water level with a return period of 5 years, 10 years, 25 years, 50 years and 100 years. Peak discharge obtained using Snyder HSS is obtained in return periods of 5 years, 10 years, 25 years, 50 years, and 100 years, amounting to 4209,558 m3 / sec, 4933,268 m3 / sec, 5627,375 m3 / sec, 5847,525 m3 / sec, and 6524,949 m3 / sec. Calibration winding in the Bereng area of the Kahayan River Workshop was completed with a third-order polynomial regression equation as follows: y = -2.7103x3 + 104.48x2 - 763.96x + 1323 with a correlation value (R²) = 0.945. As for the results of using the HEC-RAS 4.1.0 program, the discharge in the return periods of 5, 10, 25, 50, and 100 years is 4100 m3 / s, 5000 m3 /, 5500 m3 / s, 6000 m3 / s, and 6500 m3 / s, with Froude number 0.11 or Fr <1 (subcritical flow).

In geotechnical constructions incorporating geomembranes and geotextiles, the interfacestrength of the two geosynthetics is of the most concern. Some researchers found considerably low values of the strength from various devices. This research aimed at contributing the interface strength database with a ring shear device for simulating large displacements commonly mobilised in the field when failures occur. The interfacing geomembranes were VLDPE, smooth HDPE, PVC and textured HDPE. Values of residual for the geomembrane-geotextile interfaces were found to be independent of stress level. They vary widely from 6.1 to 33.8 degree, and are controlled mainly by the texture and stiffness of geomembranes, and the types and arrangement of filaments composing the geotextile. The lower value is for a smooth HDPE with a geotextile comprising glossier filaments, while the higher value is mobilised by the textured HDPE against a geotextile with filaments that are best-interwoven. Of all interface combinations, the ring shear tests with a smooth HDPE geomembrane always resulted in lowest residual interface strengths.

Jembatan Pulau Balang dibangun melintasi teluk Balikpapan menghubungkan Kabupaten Penajam Paser Utara dengan Kotamadya Balikpapan. Bangunan atas Jembatan Pulau Balang adalah cable stayed yang disokong oleh 2 buah pylon. Struktur bawah dari Pylon disokong oleh kelompok bored pile dimana pada saat pengecoran ditemukan volume aktual beton lebih besar dari volume rencana pile. Penelitian ini bertujuan mengetahui perubahan dimensi lubang bor dan daya dukung bored pile karena perubahan dimensi lubang bor tersebut. Analisis dilakukan dengan membandingkan daya dukung rencana, daya dukung aktual, dan daya dukung yang didapat dari pengujian beban bi-aksial Osterberg Cell Test. Dari perhitungan daya dukung menggunakan persamaan daya dukung selimut daya dukung ujung dan pengujian daya dukung berdasarkan OC Test didapatkan daya dukung aktual lebih dari daya dukung rencana, dan lebih dari daya dukung hasil pengujian lapangan. Didapatkan juga perbedaan diameter aktual lubang bor tidak berhubungan dengan jenis lapisan tanah yang ada. Besarnya kenaikan daya dukung hasil OC test terhadap 2xQizin tidak sebanding dengan kenaikan akibat pembesaran diameter tiang. Sehingga kenaikan besarnya hasil OC test dapat disebabkan oleh pembesaran diameter atau bersama-sama dengan faktor lain.

The purpose of this study was to obtain the optimum base ash content that can be used as a substitute for fine aggregate for concrete mixtures. In this study, mortar samples were made with variations of bottom ash as a substitute for fine aggregate ranging from 0%, 10%, 15%, 25%, 35%, and 50%. In addition, the compressive strength of mortar samples was tested at 3 days, 7 days, 14 days, 21 days, and 28 days. Furthermore, the concrete sample was also prepared with f’c set at 25 MPa. Concrete samples were tested at 3 days, 7 days, 14 days, 28 days and 56 days. From these results obtained the optimum compressive strength of mortar from a mixture with a base ash content of 10% at the age of 28 days which reached 9.57 MPa. However, this result is still below the normal mortar yield of 11.58 MPa. As for the concrete sample, the highest compressive strength was obtained at the age of 56 days, which was 29.06 MPa for concrete with a base ash content of 10%, while normal concrete was 35.01 MPa. The results of this study indicate that increasing the age of the concrete increases the compressive strength. The compressive strength of concrete with 10% bottom ash decreased before 28 days, but after 28 days the compressive strength was able to reach the targeted f’c of 25 MPa.

Currently, Asphaltic Concrete (AC) is widely used as a surface layer in road construction in Indonesia because of its waterproof, durable, structural value and can be used for light to heavy traffic. There are various asphalt mixtures, such as hot asphalt mixtures using rock ash filler, cement and lime on the surface layer of the Asphaltic Concrete Wearing Course (AC-WC). Therefore, it is necessary to conduct research to determine Marshall characteristics in the evaluation of hot asphalt mixtures using rock ash, cement and lime fillers on the Asphaltic Concrete Wearing Course (AC-WC) surface layer which is adjusted to the specifications of Indoneisan Highways. Marshall test results on the AC-WC mixture using 3 different types of filler such as rock ash filler, cement and lime with Marshall parameters. In the stone ash filler test, the optimum asphalt content was 5.8% with Marshall parameters namely Stability (1180 kg), Flow (3.75mm), MQ (339kg/mm), VIM (4.75%), VMA (17.4 %), VFB (79.5%). For Cement Filler, the optimum asphalt content is 5.7% with Marshall parameters namely Stability (980 kg), Flow (3.8mm), MQ (260kg/mm), VIM (5.26%), VMA (17.8% ), VFB (75%). As for the Lime Filler, the optimum asphalt content was 6.6% with Marshall parameters namely Stability (1060 kg), Flow (3.7mm), MQ (310kg/mm), VIM (5.25%), VMA (19%), VFB (79%). In addition, the Marshall immersion test with IRS values obtained results of 88.45%, 91.52% and 84.36% for rock ash filler, cement filler, and lime filler respectively, where all results meet the minimum specification requirements of 75% based on Indoneisan Highways specification.

This study aims to determine the compressive strength conversion factor of various paving blocks shape to the standard test shape of paving blocks (SNI 03-0691-1996). The manufacture of paving blocks samples uses a ratio of 1:2:0.2 for cement, fine aggregate, and coarse aggregate. This study used a mixture of 15% fly ash as a partial replacement of cement. The shape of paving blocks were rectangular measuring 21x10.5x8 cm, hexagon with a side size of 11.5 cm and a thickness of 6 cm, and a bishop's hat measuring 30x21x8 cm. As for paving block specimens with standard shapes measuring 6x6x6 cm cubes for hexagons, and 8x8x8 cm cubes for rectangular shapes and bishop's hats. The compressive strength and water absorption of paving blocks were tested at the age of 28 days. In this study, the results of the compressive strength testing of paving blocks with standard shapes were higher than the compressive strength values of rectangular, hexagon, and bishop's hats. The amount of conversion factor obtained on paving blocks with 15% fly ash are 1.06, 1.32, and 1.13 for rectangular, hexagons, and bishop’s hats respectively. In addition, the average water absorption obtained on paving blocks with 15% fly ash are 2.92%, 2.79%, and 2.96% for rectangular, hexagons, and bishop’s hats respectively.

Traffic accidents are a problem that requires serious handling. Human factors (driver), environment, vehicles and roads are some of the factors that cause accidents. For this reason, it is necessary to analyze the existing traffic accident data. The location of the road section studied is Jalan Ahmad Yani km 17 – km 36 Banjarbaru City. The purpose of this study is to identify the location and causes of road accidents in order to provide handling efforts in accident-prone areas and points. The analysis is carried out to identify areas and points prone to accidents (blackspots) by calculating the number of fatal accidents (TF) and the UCL (Upper Control Limit) limit value. From the results of data analysis, there are 2 vulnerable areas (blacksite), namely the Jl. A. Yani km 19 – km 20 and the Jl. A. Yani km 21 – km 22. Furthermore, 8 road points were identified as Accident Prone Points (Blackspot). The accident-prone point that has the highest fatality rate is the point Jl. A. Yani km 19.25-19.50 Banjarbaru with TF = 10614.401 and UCL = 4523.506. The recommended traffic accident mitigation is to improve the awareness of road users in traffic by providing driving safety education and installing road facilities.

Preventive measures that can be taken to prevent flooding when high rainfall discharge occurs, especially in the Banjarbaru area, is to plan water structures starting with rainfall analysis, especially rainfall frequency analysis to obtain planned rainfall and rainfall intensity. Data processing is carried out with daily maximum rainfall data of 30 years. Divided into 3 databases, the number of data is 10 years (data no. 1-10), the number of data is 15 years (data no. 1-15), and the number of data is 20 years (data no. 1-20). Each database calculates the planned rainfall for a return period of 2-20 years, the results of which are compared with the rainfall data from field measurements at the Banjarbaru Climatology Station. Next, analyze the accuracy of the rainfall intensity method by referring to the results of the previously analyzed rainfall plans. The formula to determine the accuracy of the rainfall frequency and intensity method uses the Peak-Weight Root Mean Square Error test, namely by taking the smallest deviation ratio value. Based on the Statistical Parameters test, the ChiSquare test and the Smirnov-Kolmogorov test get the Normal distribution analysis, but based on the comparison analysis the smallest deviation gets the Gumbel distribution. Rain intensity analysis with the smallest deviation test gets the Sherman formula. It is suggested that rainfall data with the same characteristics can use rainfall analyzes based on the Gumbel distribution and Sherman's formula for water building plans.
