Abstract

The soil layer is the combination of many types as well as the soil in the slope area. The soil in the slope is frequently a mixture of clay and sand. The stability of slope becomes dominantly an issue in the geotechnical engineering area. The collapse of the slope occurs because the gravity of external forces is exceeding the shear strength of the soil. The recent research develops the apparatus to determine the angle of repose of the sand-clay soil in the failure conditions. Sandy soil is taken from Beach and Merapi volcano. The clay added into the sand in the proportion of 0%, 5%, 10%, 15%, 20%, 25%, and 30%. The experiment is conducted by taking the height of the falling material of 15cm, 25cm, and 35 cm. Adding 0% to 15% clay brings the sand into SP Category, then adding 20%-30% makes the sand in the SC category. The Modulus if a fine grain of sand beach is smaller than Merapi sand. As the percentage of clay added to the sand higher, the difference of angle of repose of Merapi sand before and after failure is getting smaller, but it is not the case in Beach sand. The percentage of loss of volume of Merapi sand after failure is also going down as the portion of clay higher. The loss of volume of Beach sand added by clay is getting higher in failure condition..

Abstract

Sentani Airport serves public using air transportation with increasing people mobility conditions because Jayapura is the National Activity Center, so it causes frequent accumulation of passengers in the terminal area especially during peak hours. To determine the effectiveness of the terminal in accommodating the flow of passenger movement, it is necessary to evaluate the terminal design of Sentani Airport. The method used is to calculate the number of PWS with passenger distribution patterns, calculate the standard area of terminal capacity using references from SNI 03-7046-2004 and SKEP 77/VI/2005, calculate the terminal LOS with IATA standards, measure the airport service standards based on PM 178 of 2015, processing passengers’ perceptions with IPA and QFD methods and forecasting with simple linier regression. From the analysis, Sentani Airport terminal gives passengers mobility with low service performance value, so it is rated as less optimal. In addition, the limited availability of several facilities causes the passengers feeling less comfortable. Thus, it is necessary to re-design the passenger terminal area and re-management the facilities according to Angkasa Pura standards.

Abstract

Many studies have begun to develop the concept of cracked soil. The results of research related to cracked soil are able to answer the irregularities that occur, such as the difference in the results of the stability analysis which is considered safe with the conventional bishop method, while the conditions in the field are landslides. Swelling soil is soil that is susceptible to changes in water content. This type of soil is very prone to cracking. To build infrastructure on the swelling soil type, an improvement must be made, one of which is by mixing the swelling soil with biopolymer. The results of this biopolymer mixing are then modeled in the New Slope Stability Analysis Program (NSSAP) 1.0 which refers to the concept of cracked soil. From the analysis, it was found that the slope safety factor before improvement with biopolymer was 0.305 and the safety factor after improvement with biopolymer was 2.006. From the results of this study, it can be seen that the role of biopolymers in stabilizing swelling soil is quite large, which is around 558%.

Abstract

Tulangan adalah material yang penting dalam struktur balok beton bertulang. Dalam perencanaannya tulangan harus dapat memikul gaya-gaya yang diterima baik secara vertikal, horizontal, maupun lateral. Penulangan dalam beton dibagi menjadi dua yaitu tulangan tekan dan tulangan tarik. Tulangan tarik memiliki peranan memperkuat balok dalam menerima beban lentur. Sedangkan tulangan tekan berperan menahan beban tarik yang terjadi pada balok. Seiring dengan berkembangnya teknologi perencanaan penulangan balok dilakukan dengan metode elemen hingga dalam suatu aplikasi. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana pengaruh penambahan tulangan tekan pada balok beton bertulang dengan menggunakan software ATENA 3D. Dari hasil analisis didapatkan nilai daktilitas terbesar dengan nilai 21,6969 sedangkan nilai daktilitas terkecil dengan nilai 1,1796. Untuk nilai kekakuan terbesar dengan nilai 145,6491 sedangkan untuk nilai kekakuan terkecil dengan nilai 6,4843. Dari data tersebut menunjukkan bahwa penambahan tulangan tekan pada balok beton memperkecil nilai daktilitas dan memperbesar nilai kekakuan. Pola keretakan pada balok dengan tulangan tekan cenderung lebih baik ketika menerima beban.

Abstract

In construction projects, reinforcing iron is a very important material in the implementation of construction work. The remaining iron material cannot be avoided in the field, so the figure for the remaining unused material affects the costs incurred by the contractor. Given that iron material is one of the materials with a high price on the market. One solution to reduce the amount of remaining iron material is to optimize iron cutting to get the number of pieces as needed with minimal cutting. The method used is Linear Programming with the help of the Solver Add-In program in Microsoft Excel. The research was conducted on a 3-storey building construction project, namely Puskesmas Kampung Dalam, Kab. Padang Pariaman. Works that reflect iron work on the upper and lower structures. The analysis results were obtained from 7.31% and cost Rp. 27.067.887,-.  for the ironworks reviewed. So that the use of the Linear Programming method in the case study of this research is able to optimize the remaining iron material quite well and produce minimum remaining reinforcing iron.

Abstract

 In soil mechanics, soil is generally categorized as sand and clay. The term sand represents a cohesionless coarse-grained while clay is a fine-grained soil with shear strength mainly derived from cohesion. In loose conditions the sand has low shear strength and is prone to shear failure. Many studies have been carried out to study the strength properties of sand and clay mixtures. In this case, the effect of clay content on the angle of repose is studied and also on the shear strength of the sand tested through direct shear testing. In addition, sand density testing was performed to identify the mechanism of shear strength increase when the sand is mixed with clay. That the angle of repose of the sand used in this study was 30o. The angle increased liniearly with the addition of clay because the clay which has finer grain characteristics can fill the void of sand resulting in a more stable mound with steeper angle.  From the direct shear test results, it was found that the addition of clay resulted in an increase in the internal shear angle. The soil cohesion increases with the addition of clay up to 20% and then decreases. The same results were obtained from the results of the soil density test where the maximum sand density was obtained at the clay content of 20%-25%.
