<![CDATA[Multigrade asphalt use is an alternative method for handling road deterioration problem, e.g. a rutting, due to the repetitive traffic load and high pressure from vehicle wheels. In addition, the multigrade asphalt has been widely used to reduce temperature sensitivity of the asphalt mixture in flexible pavement due to an unpredictable climate change. Rutting is also caused by the accumulation of permanent deformations from all layers in the pavement structure. This study aims to analyze the permanent deformation value and the resilient modulus of an Asphalt Concrete Binder Course (AC-BC) modified mixture through the use of multigrade asphalt. The Wheel Tracking Test and UMATTA Test were used to test the specimens. The Tests on samples were carried out at temperatures of 35oC and 50oC. The results showed that the permanent deformation value of the AC-BC with multigrade asphalt had a better deformation resistance than the 60/70 pen bitumen mixture at 35oC. At the temperature of 50oC, the multigrade asphalt mixture had a smaller permanent deformation value (0.92 mm) compared to the 60/70 pen bitumen mixture. At the temperature of 35oC, multigrade asphalt mixture had a resilient modulus value of 1.04 times greater than the 60/70 pen bitumen mixture and at the temperature of 50oC, this mixture had a resilient modulus value of 1.16 times greater than the 60/70 pen bitumen mixture. Therefore, this study concluded that the increase/decrease of value of permanent deformation and resilient modulus were influenced by the temperature and types of asphalt in the mixture.]]>

<![CDATA[One reinforced beam element that experiences a shear failure is a high beam; a beam that follows a requirement based on SNI-2847-2013 standard that have the proportion of sliding span (l) and the effective height (d) not more than three. The type of collapse in high beams generally is shear failure in which the crack appears from the area around the placement, propagates and reaching the maximum value at the point of loading. Observation of crack patterns and ultimate loads can be done by several methods based on both non-linearity and linearity of materials. Two specimens consisted of one high beam conventional reinforced concrete and one high beam concrete fiber with a dimension of 170 mm x 420 mm x 850 mm were prepared. Fiber from machine turning waste was used as coarse aggregate substitution with 100% composition in fiber concrete. Both specimens were tested in the laboratory and observed for crack patterns analysis and ultimate load achievement. The experimental test results were then compared with the numerical test results for the non-linearity properties of the material and the Strut and Tie method for the linearity properties of the material. The ultimate high beam of conventional reinforced concrete when experiencing shear failure in the experimental method, numeric method, and strut and tie method were 310 KN, 290 KN, and 236.917 KN respectively, whereas in the high beam fiber concrete, the ultimate load in the experimental method, numeric method, and in the strut and tie method were 280 KN, 260 KN, and 263,917 KN respectively. The biggest ratio of test results were obtained from the comparison between the numerical and the experimental methods in conventional concrete which was equal to 0.94. This showed the similarity of non-linearity properties of the material to produce adjacent test results.]]>

<![CDATA[The collapse of a column causes the collapse of the entire building that need a large cost for repairing. Therefore, special attention is needed when planning the columns, i.e. by providing a backup strength on columns which greater than other beams and other horizontal structural elements since there is no initial warning in a press-type of collapse. This study aims to determine the efficiency of square concrete column dimensions in case of column calculations after the revision of PBI 1971 to SNI 1991 standard both by manual calculation and using the Turbo Pascal-based application. Calculation utilized the elastic method and ultimate method with the assumption that column conditions are similar as well as the column data is taken from the calculation of reinforced portal structures. Concrete columns are made rectangle with dimensions of size 35 x 35 cm and size 75 x 75 cm, concrete quality K 225, steel quality U24 (2400 kg / cm²), modulus of steel elasticity 2.1. 10ⶠkg / cm² and 5 cm thick of concrete blanket, with the assumption that structural analysis has been conducted for calculating the boundary and moment loads, assuming that the column conditions are similar. In case of the ability to retain the load and moment by the column, assuming the constant area of ​​reinforcement in various dimensions, the results of the elastic method (PBI 1071) were smaller than the ultimate method (SK SNI 1991). The calculation results showed that the ultimate method was more efficient than the elastic method in terms of the efficiency of reinforcing steel use.]]>

<![CDATA[Kota Pangkalpinang sebagai Ibukota Provinsi Bangka Belitung menjadi pusat kegiatan yang menimbulkan pergerakan kendaraan yang tinggi, dimana tingginya pergerakan kendaraan akan mempengaruhi besarnya kebutuhan ruang parkir. Penyediaan ruang parkir di Kota Pangkalpinang tidak hanya menggunakan lahan parkir, namun juga menggunakan badan jalan sebagai tempat parkir kendaraan atau yang disebut parkir di tepi jalan umum. Implementasi kebijakan tarif parkir di tepi jalan umum di Kota Pangkalpinang dinilai belum berjalan secara maksimal. Penelitian ini bertujuan untuk mengevaluasi tarif parkir di tepi jalan umum Kota Pangkalpinang berdasarkan zona yang telah ditetapkan untuk mengetahui kesesuaian tarif parkir di tepi jalan umum yang berlaku saat ini. Evaluasi tarif parkir di tepi jalan umum dianalisis berdasarkan Ability To Pay (ATP) dan Willingness To Pay (WTP). Hasil penelitian menyimpulkan bahwa tarif resmi parkir di tepi jalan umum yang ditetapkan, baik untuk kendaraan roda 2 maupun kendaraan roda 4 masih terlalu rendah dan masih bisa ditingkatkan. Penyesuain tarif resmi dapat dilakukan mengikuti rata ? rata tarif yang berlaku atau lebih, namun idealnya tidak melebihi nilai ATP. Dalam penyesuaian tarif, hasil yang diperoleh dapat menjadi bahan pertimbangan Pemerintah Kota Pangkalpinang dalam mengevaluasi kebijakan tarif parkir di tepi jalan umum yang berlaku saat ini.]]>

<![CDATA[Nowadays, delays in project often occur and cause various losses both for service providers and users. For the contractors, delays create the project cost overruns due to project overtime and can decrease contractor credibility in the future. This study aims to analyze a project delay by minimizing the work delays earlier. The analysis of a hotel building planning regarding the cost and time delays is done qualitatively by distributing questionnaires to the contractors and processing the responses using the SPSS software. The results of the S curve analysis and 30 factors that caused the project delay were identified and indicated that there was a delay value of 1.26% with five variables that most contributed to the delay in the construction project at PT. Wijaya Kusuma Contractors, i.e. reworking due to construction errors, low coordination between contractors and stakeholders, late material delivery, and equipment shortages.]]>

<![CDATA[Pangkalpinang City, the Capital of Bangka Belitung province, is the center of various activity with the characteristic of high vehicle trips; therefore, the larger parking spaces are needed. The parking spaces in this city utilizes not only the parking lots but also on-street parking. The implementation of on-street parking fee policy recently has not run optimally. This study aims to evaluate the on-street parking fee in Pangkalpinang City based on the parking zone to determine appropriate parking fee. In this study, the evaluation of on-street parking fee was analyzed based on Ability To Pay (ATP) and Willingness To Pay (WTP). Result showed that the existing parking fee for motorcycle and car is too low and needs to be revised. The existing parking fee can be adjusted to more than the average real parking fee but ideally the fee should not more than the ATP value. This result can be used as a guidance for Pangkalpinang City Government to evaluate the on-street parking fee policy.]]>
