Abstract

The low location of the Banjar district land from the sea surface causes the flow of water on the soil surface becomes substandard. Consequently some areas always stagnant to reach 29.93 %, some 0.58 % flooded periodically. Almost every year when the rainy season arrives with a high intensity in the Martapura area there is a flood with an altitude of up to ± 1 meter. Based on data of regional disaster management agency (BPBD), there are eight districts that are prone to flooding. Namely, Sungai Pinang district, Sambung Makmur, Pengaron, Astambul, Karang Intan, Martapura, Sungai Tabuk, dan Mataraman. Research was conducted with the help of Arcgis software using a calculate geometry tool to identify morphometry. Watershed morphometry is a quantitative measure of watershed characteristics associated with the geomorphological aspects of a region. These characteristics are related to the rainwater drainage process that falls within the watershed. The research results show watershed Martapura has an area of 453.88 km2, the length of the main river reaches 36,566 meters, the slope (gradient) of 0.022 %. River density level is 0.828 km/km2.The order level of the river reaches 10 level. The pattern of the river is rektangular with the type of watershed in parallel. Based on data mapping and identification of Martapura river basin, so that important. information can be generated. such morphometric data can be used as reference for environmental problem solving and watershed management.

Abstract

Sungai Bitahan  berada di Kabupaten Tapin yang tepatnya berada di Desa Bitahan. Sungai ini merupakan sungai keberadaannya sangat penting bagi masyarakat, karena sebagian besar masyarakat yang beraada di sepanjang tepian sungai menggunakan air dari Sungai Bitahan untuk memenuhi kebutuhan sehari - hari dan juga untuk pengairan daerah persawahan serta perkebunan. Meskipun telah dibangun pengaman tebing sungai namun dalam perencanaannya kebanyakan tidak melakukan pengamatan lebih jauh tentang predikdisi tinggi debit air sungai pada musim hujan dan tidak melakukan normalisasi dasar sungai serta peninggian tebing sungai untuk menghindari terjadinya luapan pada sungai. Penyusunan laporan dilakukan dengan metode pengamatan lapangan dan perhitungan. Untuk pengukuran penampang sungai menggunakan metode manual. Lokasi pengukuran penampang yang harus diperhatikan, yaitu lebar sungai, kedalaman sungai dalam jumlah 10 titik, Tinggi muka air normal. Perhitungan kecepatan menggunakan Rumus Manning , Debit merupakan jumlah air yang mengalir di dalam saluran atau sungai per unit waktu. Metode yang umum diterapkan untuk menetapkan debit sungai adalah metode profil sungai (cross section), Dari klasifikasi Sungai, Sungai Bitahan termasuk sungai kecil dengan lebar antara 3 – 10 m. Kecepatan aliran pada saluran Sungai Bitahan kondisi normal menggunakan Rumus Manning adalah 4,25 m/det. Untuk saluran Sungai Bitahan setelah di normalisasi didapat kecepatan aliran yang menggunakan rumus Manning adalah 4,86 m/det, Untuk debit aliran saluran sungai kondisi existing pada Sungai Bitahan adalah 119,27 m3/det, debit aliran untuk saluran sungai setelah di normalisasi adalah 148,57 m3/det. Dimensi saluran pada Sungai Bitahan setelah dinormalisasi menggunakan tanggul siring berbentuk dinding kantiliver dengan lebar atas saluran A = 0,4 m, untuk lebar dasar salurannya B = 2,80 m dengan tinggi saluran H = 4,00 m dan tebal kaki pondasi D = 0,40 m. Dan hasil perhitungan daya dukung tanah pondasi untuk dinding penahan tanah kantiliver dengan keadaan tanah timbunan kering ( ), stabilitas terhadap penggeseran dinyatakan aman Fgs = 2,44 , stabilitas terhadap penggulingan aman Fgl = 2,91 dan daya dukung  F = 6,83. Dinding penahan tanah kantiliver dengan keadaan tanah timbunan jenuh (), stabilitas terhadap penggeseran dinyatakan aman  Fgs = 3,21, stabilitas terhadap penggulingan aman  Fgl = 3,28 dan daya dukung aman FK = 11,77.

Abstract

In the province of East Kalimantan, especially the city of Tana Paser, Paser Regency, has a fairly high population growth, and is a fairly dense city and it is included as a fairly developed city hence many migrants who migrate to trade or to find a job. Based on the results of the Central Bureau of Statistics recording in 2016, the population of Tana Paser city was 50,000 people which make the city of Tana Paser as the city with the largest population in the Southern part of East Kalimantan Province. To find out the traffic density level, it is necessary to analyze and survey the traffic,  the results of the analysis show that the surveyed road with the highest density level or the highest Degree of Saturation (DS) is MT Haryono road with DS value of 0.494 with road capacity of 1406 , 725 SMP / hour and total of traversing current of 694,4 SMP / hour followed by road of Untung Suropati with DS equals to 0,441 with road capacity of 2134,458 SMP / hour and total of traversing current equal to 942,350 SMP / hour. For the surveyed road with the lowest density level or the lowest Degree of Saturation (DS) is the Pelopor road with DS value of 0,020 with the road capacity of 2229,323 SMP / hour and the total traversing current is only 45,100 SMP / hour; then Sungai Tuak Sultan Hasanuddin road with DS value of 0,066 with road capacity of 3305,275 SMP / hour and total traversing current only equals to 217,050 hence the road is categorized as quiet road.

Abstract

The soil layers in Banjarmasin are generally soft clay soil, whereas hard soil layers are in the range of 30 to 50 matters below ground level. Therefore, deep foundation is the right alternative to build a stronger and more stable construction. This study aims to determine the comparison value of pile bearing capacity based on theoretical and actual result so it can be used to determine the selection for planning and execution in installation of piles foundation. The study was conducted at Lambung Mangkurat University (ULM) Campus, Jl. Brigjend H. Hasan Kayu Tangi, Banjarmasin. This study used mini piles size of 20cm x 20cm with vary in length. The type of soil bearing capacity against piles is friction. In theoretical calculation, it used sondir data while in actual bearing capacity it used the result from loading data test at pile B, E, G and I, then all data processed and analyzed by using methods from Davission  (1973), Mazurkiewich (1973), and Chin (1970). The results of the calculation of bearing capacity of the ultimit piles, both theoretical and actual show a very significant difference. A very large difference on pile E4 with a depth of 12 meters of 53,25%, and the smallest difference  in pile I with a depth of 12 meters by 15,25%.

Abstract

The cause of the failure and damage to the roughness of the road is because the use of asphalt with high penetration value concurent with low levels mixture asphalt and the implementation of which has not been in compliance with the existing requirements, thus reduce the age of the road plan. The most commont asphalt roughness layer failure is permanent deformation AS a result of less stability and crack due to fatigue. One of the main consideration in determe the quality of asphalt mixture is the strength of the aggregate in order to endure in compliance with road planning. The issues discussed in this research is how the combined aggregate influence towards optimum levels of asphalt and asphalt mixture stability value. The research sample is asphalt penetration 60/70, coarse aggregate Awang Bangkal and Katunun-Banjarbaru Pelaihari, fine aggregate is Barito sand, filler Awang Bangkal rock burst and Tiga Roda Cement, witch total of 48 samples with levels 5-7% asphalt. Parameters of mix are stability , flow of air cavities, Voids in Mix (VIM), Void in Mineral aggeggate (VMA), Void Filled with Asphalt (VFA), Marshall Quotient (MQ), and VIM refusal to AC-WC determined from analysis of Marshall. The result achieved is the reduction in consumption levels of optimum asphalt of 0.5% for combined aggregate Awang Bangkal and Katunun Lataston mixed HRS-WC and a reduction in consumption levels of optimum asphalt of 0.2% on the mix HRS-Base on the minimum spesification 800 kg.
