Abstract

Dalam suatu pekerjaan struktur seringkali dijumpai pekerjaan perbaikan atau perkuatan struktur beton. Permasalahan yang sering muncul pada pekerjaan perbaikan atau perkuatan struktur terletak pada lekatan antara beton lama dan baru, dimana pertemuan (interface) merupakan bagian terlemah dari struktur. Penelitian ini bertujuan untuk mengetahui kinerja kuat geser lekatan interface antara beton lama (substrate) dengan beton baru (overlay) dengan variasi sudut kemiringan dan volume fraksi serat baja pada beton baru. Metode yang digunakan adalah metode Slant Shear Test, dengan menggunakan benda uji berbentuk prisma dengan dimensi 150 x 150 x 300 mm. Terdapat 2 variasi yang digunakan yaitu, (1) variasi sudut kemiringan 30°,45°, dan 70°dan (2) variasi campuran serat baja pada lapis overlay sebesar 0%, 0,5%, 1% dan 1,5%. Pada setiap variasi dibuat benda uji kuat tekan (kubus 150 x 150 x 150) dan kuat tarik lentur (balok 100 x 100 x 400). Dari hasil penelitian dapat disimpulkan bahwa 1) Kemiringan interface antara beton lama dan beton baru terhadap arah beban tekan mempengaruhi kuat geser lekatan antara beton lama dan beton baru, 2) Penambahan serat baja dalam beton overlay dapat meningkatkan kuat lekatan antara beton lama-baru dan kuat tarik lentur beton.  Kata kunci : kuat geser, interface, substrate, overlay, kuat tarik lentur.

Abstract

Gasoline is an important item and becomes a basic need for the community. Subsidized gasoline in Bandar Lampung experienced sales restrictions according to the specified quota. The price of subsidized gasoline which is cheaper than non-subsidized gasoline makes people willing to wait to get subsidized gasoline. This study aims to determine the factors that influence the selection of gasoline types and determine the preferences of each private vehicle user in choosing gasoline, both subsidized gasoline and non-subsidized types. This research uses AHP (Analytical Hierarchy Process) methodBased on the results of the analysis conducted on the group of civil servants, non-civil servants and students, it was found that the group of non-civil servants chose Premium which was the most priority with a weighting value of 0.3745, then for Pertalite of 0.3156 and Pertamax 0.3108. Then for the group of civil servants, the greatest or priority results were Premium with a value of 0.3457, then Pertamax with a value of 0.3350 and Pertalite with a value of 0.3205. Then, for the Student group the most priority results are Premium of 0.3479, then Pertalite of 0.3288 and Pertamax with a difference not too far at 0.3263.

Abstract

The train is a means of transportation favored by the community because the train is one of the modes of transportation that has special characteristics and advantages. Along with the development of infrastructure development in Lampung Province and South Sumatra Province, the planning and design of a building must be done carefully and well, one of them is by building a double track between Giham - Martapura, South Sumatra because the application of one track has many obstacles. It is hoped that the addition of the double track can make the train schedule more timely and can improve the quality of the trip. Based on the results of the Atterberg boundary test the soil originating from the undisturbed soil sample of the Giham-Martapura railroad gets an PI value <LL-30 (26.51% <27.95%), then the land based on the AASHTO system is classified into A -7-5 that is clay soil and as subgrade material has normal to poor evaluation. Keywords: railroad, land, double track, slope protection.

Abstract

The level of slope safety is influenced by several factors. Such as slope conditions with largeloads, steep slopes and heavy rain conditions. This often results in landslides around the TransSumatra toll road, Pematang Panggang. So that around the slopes reinforcement is needed so thatthe slopes are more stable.Based on the results of laboratory tests and research in the field, the results of the calculation ofthe slope safety value program with a 30% saturation degree condition, the safe factor value is1.2946, the degree of saturation 40%, the safe factor value is 1.2881 and the degree of saturationis 60%, the safety factor value is equal to 1,2761. Because the lowest safe factor value is at 60%saturation degree, slope stability is handled at 60% saturation degree, which is strengthened bythe cutting method on the slope body and using sheet pile to get slope reinforcement. Two methodsof handling slope stability were carried out. From the comparison of slope stability handling with60% degree of saturation, the safe slope conditions are in handling one because there is nosubsidence and soil displacement to the free slope area.

Abstract

Soil is a material to build any infrastructure. So, soil becomes very important and influential in construction. Soil quality determine the power of construction on it, the good soil is soil that has a high density in each particles and contain less water levels. The quality of soil is depending on physic and mechanic soil condition, that’s why we need to test it out. Soil compaction is process of increasing the soil density by reducing the particles proximity so it can reduce the air volume. Compaction is divided into four types. In this research is using two types of compactions that are type A and Type C with purpose to find out the effect of soil particles diameter by passing sieve analysis to soil compaction.Compaction is done based on blow method and pressure method. In pressure method is using modification compaction tool with 5 Mpa, 10 Mpa, and 15 Mpa pressures.The result of this research can be conclude that the blow method compaction type A has a higher water content than type C, but the value of maximctum dry volume weight Type C higher than type A. In pressure method it can be concluded that as the higher pressure so the water content and the maximum dry volume weight are also getting higher.

Abstract

The code about concrete compressive strength progress is presented on Table 4.1 of PBI 1971. But the concrete compressive strength development in many current concrete construction projects often face one similar major problem which is the incompability between concrete compressive strength progress compared to PBI 1971. To identify that problem, this research was done by creating 160 cube concrete samples from OPC and 120 cube concrete samples from PCC by using 4 different PCC and OPC brands that consist of Dynamix, Baturaja, Tigaroda and Padang. Moreover, the samples are consists of 2 different targeted concrete compressive strength which are K250 and K400 and the samples were tested in the age of 7, 14, 21, 28 and 56 days. Aside of that, the chemical properties in each of used cements that consist of Tricalcium Silicate (C3S), Dicalcium Silicate (C2S), Tricalcium Aluminate (C3A) and Tetracalcium Aluminoferrit (C4AF) were also tested to identify the impact of chemical properties of cements to the compressing strength progress of all samples.Based on the research, it was identified that the chemical properties of cements that consist of C3S, C2S, C3A and C4AF were very influential in the process of compressive strength progress of all samples. In addition, the coeffiecients presented on SNI-15-2049-2015 Chapter 5 Table 5 used to calculate the percentage of C3S, C2S, C3A and C4AF need further reviews. Last, it was known that the compressing strength development of both OPC and PCC samples were not aligned to the PBI 1971 estimation. Besides, the procedure of all samples have followed the British Standard and ASTM regulation. In conclution, based on the research PBI 1971 was no longer relevant to be used as the reference for concrete compressing strength progress. Keywords: Concrete, compressive strength progress, cement chemical properties, incompability, tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite.
