Abstract

Abstract: Traffic jam at signalized intersections, are a problem generally occurred in Indonesian cities, including Mataram City, Lombok Island, West Southeastern Nusa Province. Such problem is affected by the increasingly large number of vehicles and the limited road paths. Therefore, the objectives of the study are to examine the intersection performance of Gomong and compare the results of analysis based on manual calculation using MKJI and using KAJIsoftware. Data were collected through recording and direct measurement in the site of the study. The data collected were then processed in laboratory to examine the intersection performance. The signalized inter-section performance was analyzed using MKJI 1997 method and given solutions to solve the prob-lem related to the intersection performance. The solution used to solve the problem was analyzed for the performance in the next 5 years. To compare the results of analysis by using KAJI soft-ware, the calculation was carried out in the existing condition of an intersection by using alterna-tive solutions used. The results of analysis show that the signalized intersection performance of Gomong was not in accordance with the standards determined in MKJI 1997 (Showed by value of DS 1.556 >standard 0.75). The comparison using KAJI software shows that the basic parameters of calculation do not significantly different (1.18% for existing condition and 1.01%Abstrak: Kemacetan lalu lintas merupakan masalah yang umum terjadi di kota-kota besar di In-donesia, termasuk Kota Mataram yang terletak di Pulau Lombok, Nusa Tenggara Barat.Kemacetan lalu lintas dipengaruhi oleh semakin banyaknya jumlah kendaraan dan terbatasnya ruas jalan. Oleh karena itu, tujuan dari penelitian ini sendiri adalah untuk mengetahui kinerja simpang empat Go-mong dan membandingkan hasil analisis antara hitungan manual MKJI dan software KAJI.

Abstract

Abstract: The lot deposit of Domato Stone as local material from sea location in Banggai island in half Sulawesi of Indonesia. Was still not be exploited better. Some research in the field of road construction showed that Domato Stone was powerful enough when mixture asphalt structure. Permeable asphalt pavement or porous friction course is commonly known as porous asphalt. The porous pavement used in Japan and Europe. The pavement consists in a porous overlay allowing rainwater to flow down to the bottom the overlay and then to drain on the edges of the pavement. Quality of porous asphalt was developed to drain pavement surface flow through its pores, because of is specific properties to measure its ability to drain the water ( Permeability ), a special measur-ing device is required. This study is aimed to measure the coefficient of permeability using the constant head permeability test at transportation laboratory Hasanuddin University. The result was compared with the previous study. The test included horizontal and vertical permeability. Their types of gradation were incorporated to: British Graduation, Binamarga Gradation, and Australian Gradation. The tests were carried out at optimum bitumen content, the result shows that the verti-cal permeability of porous asphalt using British Gradation were: 0,0914, 0,2841 and 0,2912 Cm/sec. Respectively meanwhile for horizontal permeability were 0,1168, 03212, 0,2897 Cm/Sec. The Marshall stabilities were at on contrary to the permeabilities, the porosity was comparable to the permeabilities. The results of researches indicate that porous asphalt mixture showed an influ-ence on the value of the characteristics of porous asphalt particularly at concrete waste fraction grading 50% retained 1/2 " and 50% natural crushed stone retained 3/8" where the values obtained from the analysis of optimum binder content is 9.5%. Based on the Scanning Electron Microscope (SEM) can be seen the microstructure and content of chemical elements present in the porous as-phalt which prove that all elements of the liquid asbuton and concrete waste can blend and bind well.

Abstract

Abstract: Installation of driving pile foundation is causing excess pore water pressure on saturated clay. Experimental study of driving pile installation effect on clayey silt is conducted at laboratory scale through pore water pressure value observation. The pore water pressure value was read using pressure transducers and head-meters, which has been installed at different depth of the soil sample. The experiment was carried out on two different soil samples. Sample 1 requires 146 strokes to fully drive, and Sample 2 requires 50 strokes. The pore water pressure value was affected by pile penetration depth. The pore water pressure at the bottom of the sample is higher than pore water pressure at the top of the sample. Excess pore water pressure at the sample with more stroke numbers is greater than the sample with less stroke numbers. Pore water pressure change values at Sample 1 are 0,04 kg/cm2 at the top of the sample and 0,10 kg/cm2 at the bottom, while at Sample 2 are 0,02 kg/cm2 at the top of the sample and 0,06 kg/cm2 at the bottom.Abstrak: Pemancangan fondasi tiang mengakibatkan perubahan tekanan air pori pada tanah lempung jenuh.

Abstract

Abstract: Open web steel joist (OWSJ) is a lightweight beam structural system that is widely used since the 1900s. It generally composed by T section as flanges on top and bottom, and L sec-tion as an open web on the centre. However, many modifications of OWSJ is commonly seen in construction sites, one of them is the usage of channel sections as top and bottom flange, and rebar steel as the open web. This configuration is mainly used to reduce cost and ease the material sup-ply. The modified OWSJ have potential to act differently than the regular one, hence scientific study need to performed to know the behaviour of the modified system. In this paper, comparison on analytical and finite element approach is conducted. The analytical method is done by mechani-cal calculation assuming there are no buckling of the flanges, web rebars are calculated individual-ly. In real structure, buckling may occur and web rebars also work concurrently. Therefore, finite element analysis with LUSAS software is conducted. The purpose of this research is to know the behaviour of OWSJ in FEM analysis. Result displays lateral torsional buckling is happen and to overcome this problem, gradation of web size is tested, resulting maximum of 10.6 % increase in capacity.

Abstract

Abstract: Time Sweep (loading time) is one of the main variables affecting the performance of asphalt related to loading resistance on the road surface. To describe the loading time effect on the viscoelastic properties of asphalt pen 80/100 with varying content of pure Asbuton with dif-ferent time sweeps, the basic rheological characteristics and mechanical rheological properties were measured with a dynamic shear rheometer in the laboratory. Complex shear modulus (G*) decreased, phase angle values increased, and strain value increased with increasing load-ing time. Vehicle speed and loading frequency were inversely proportional to loading time; thus, it can be concluded that increasing the vehicle speed and increasing the vehicle loading frequency will cause an increase in G*, decrease in phase angle, and decrease in strain. Bitu-men stiffness modulus (E *) was inversely proportional to the increase in loading time. Perma-nent deformation damage criteria, both before and after mechanical rheology test (RTFOT), showed that the shorter the loading time, the stronger the bitumen is in resisting permanent de-formation damage. Based on fatigue cracking criteria, all combinations of loading time and Asbuton content fulfill the statutory requirements for fatigue cracking resistance. Abstrak: Waktu pembebanan (Time Sweep) merupakan salah satu variabel utama yang mempengaruhi kinerja material aspal yang berkaitan dengan ketahanan terhadap pembebanan pada perkerasan jalan. Untuk dapat memperoleh gambaran dari pengaruh variasi waktu pem-bebanan terhadap sifat reologi visco-elastic aspal pen 80/100 dan Asbuton murni maka dil-akukan pengujian sifat reologi dasar dan sifat reologi mekanistik dengan alat Dynamic Shear Rheometer dengan beberapa variasi kadar Asbuton murni. Hasil peneitian menunjukkan pen-ingkatan waktu pembebanan menyebabkan penurunan nilai complex shear modulus (G*), pen-ingkatan nilai phase angle, dan peningkatan nilai regangan. Jika hasil ini dikaitkan dengan ke-cepatan kendaraan dan frekuensi pembebanan yang berbanding terbalik dengan waktu pem-bebanan, maka dapat disimpulkan bahwa peningkatan kecepatan kendaraan dan bertambahnya frekuensi pembebanan kendaraan akan menyebabkan peningkatan nilai G*, penurunan nilai phase angle, dan penurunan nilai regangan pada sampel. Dalam tinjauan modulus kekakuan bi-tumen diperoleh peningkatan waktu pembebanan menyebabkan penurunan modulus kekakuan bitumen. Dalam kajian kriteria kerusakan Permanent Deformation baik pada kondisi original maupun pada kondisi setelah RTFOT dapat disimpulkan bahwa semakin kecil waktu pem-bebanan maka semakin kuat bitumen tersebut dalam menahan kerusakan Permanent Defor-mation. Sedangkan, dalam kajian kriteria kerusakan Fatigue Cracking dapat disimpulkan bah-wa seluruh kombinasi waktu pembebanan memenuhi persyaratan jika dilakukan tinjauan ketahanan material terhadap fatigue cracking.
