Abstract

abstractMusi IV Bridge is one of the new bridges currently under construction in Palembang City. The construction of the bridge is aimed to unravel the congestion that occurs at the Ampera bridge and is also useful to increase the accessibility of the community movement from ilir to ulu plaju so as to reduce the waste of time, energy and costs.This bridge has a total length of 1130 m and 12 m width. But the calculation is only calculated from A1 (Abutment 1) to P1 (Pillar 1) or Musi IV Bridge STA 0 + 114.5 - 0 + 153, where the span length is 38.5 m, width is 12 m, and has an elongated girder 4 pieces with a distance between girder 3.1 m.The main structure of this bridge is in the form of Strategic U Block (PCU), with post-pull method and 29.05 MPa concrete quality. For floor slabs using reinforced concrete construction using the insitu method, so there will be a composite action between precast beams and cast plates in place. The bridge abutment and pillar building also uses the method of insitu (cast in place). Based on the results of SPT (Drill Log) testing, hard soil is at a depth of 35 meters. The relatively deep hard soil location is used pile foundation with carrying capacity utilizing the ground stress below and shear stress around the pile foundation blanket.This bridge construction refers to RSI T-02-2005 (Loading Regulations for Bridges), RSNI T-03-2004 (Concrete Structure Planning for Bridges). In addition, this bridge planning also takes several library resources as reference material.Key Word : Transportation, Musi IV Bridge, Prestressed Concrete ABSTRAKJembatan Musi IV  adalah salah satu jembatan baru yang sedang dalam proses pembangunan yang berada di Kota Palembang. Pembangunan jembatan terserbut bertujuan untuk menguraikan kemacetan yang terjadi di jembatan Ampera dan juga bermanfaat untuk meningkatkan aksebilitas pergerakan masyarakat dari arah ilir ke ulu plaju sehingga mengurangi pemborosan waktu, energi dan biaya.Jembatan ini memiliki total panjang 1130 m dan lebar 12 m. Namun perhitungan yang dilakukan hanya di hitung dari A1 (Abutment 1)  sampai P1 (Pilar 1) atau Jembatan Musi IV STA 0+114,5 – 0+153, dimana panjang bentangnya 38,5 m, lebar 12 m, dan memiliki gelagar memanjang 4 buah dengan jarak antar gelagar 3,1 m.Struktur utama dari jembatan ini berupa Balok Prategang U (PCU), dengan metode pasca tarik dan mutu beton 29,05 Mpa. Untuk pelat lantai menggunakan konstruksi beton bertulang dengan metode insitu, sehingga akan terjadi aksi komposit antar balok pracetak dan pelat cor ditempat. Bangunan abutment dan pilar jembatan ini juga menggunakan metode insitu (cor ditempat). Berdasarkan hasil pengujian SPT (Bor Log) tanah keras berada pada kedalaman 35 meter. Letak tanah keras yang relatif dalam maka digunakan pondasi tiang pancang dengan daya dukung memanfaatkan tegangan tanah dibawahnya dan tegangan geser disekitar selimut pondasi tiang pancang.Perencanaan jembatan ini mengacu pada RSI T-02-2005 (Peraturan Pembebanan untuk Jembatan), RSNI T-03-2004 (Perencanaan Struktur Beton untuk Jembatan). Selain itu perencanaan jembatan ini juga mengambil beberapa sumber pustaka sebagai bahan referansi.Kata kunci : Transportasi, Jembatan Musi IV, Beton Prategang

Abstract

Currently, research has developed that uses various kinds of additives to improve the quality of concrete, which is of higher quality, but also increases the economic cost of building a construction. This research is a mixture of cement and rice husk ash which is expected to increase the compressive strength of concrete and increase the flexural strength of the concrete. The process of processing husk ash is by filtering using a No. 200 filter. Variations in the percentage of husk ash to the volume of cement in the mixture are rice husk ash 5%, rice husk ash 10%, rice husk ash 15%. The test is carried out within 7 days, 14 days, and 28 days based on SNI 03-2491-2002. The results of this test are the optimum concrete strength value, namely normal concrete variations with an average compressive strength value of 25,078 MPa. And to produce the optimum flexural strength of concrete, normal concrete has an average flexural strength value of 4.392 MPa. So, the results of the research on the compressive strength and flexural strength of concrete with the use of rice husk ash as a cement substitute are lower than normal concrete.

Abstract

A bridge is a construction that connects two or more separate areas. Bridges owned by PT. Bara Alam Utama is located in Banjarsari, Lahat Regency, South Sumatra. This bridge is used as an alternative way to bring mining products in the form of coal to the storage station. The total length of the bridge is 110 meters. This bridge is divided into 3 segments, namely the first segment is the beam I bridge, the second segment is the steel frame bridge and the third segment is the beam I bridge. The beam I bridge has a length of 25 m and the steel frame bridge has a length of 60 m. This bridge system uses a composite system of a combination of concrete and steel frames. The planning includes the superstructure and the substructure. From the results of the sondir test, the abutments and pillars are not able to withstand the sliding bearing capacity, therefore piles with a spunpile type with a diameter of 80 cm are used. Bridge planning is guided by RSNI T-12-2004, RSNI T-03-2005, SNI 2833-2016, SNI 1725-2016 and other library sources.

Abstract

Concrete is a structural material that is commonly used in the construction of buildings, roads, bridges and others. Concrete has a weakness, namely its specific gravity is high enough so that the dead load on a structure becomes large and the tensile strength is weak. The purpose of this study was to determine the effect of using Styrofoam waste on the compressive strength of concrete. This study uses Styrofoam waste as a partial substitution of the volume of coarse aggregate and fine aggregate with variations of 0% 5%, 10%, 15%, 20%, 25%, 30%, and 35% by using K-300 concrete quality and concrete. cube-shaped test with a size of 15 cm x 15 cm x 15 cm totaled 48 test objects. The compressive strength test was carried out at the age of 14 and 28 days of treatment. From the test results, the compressive strength of normal concrete at the age of 28 days is 318.81 kg/cm3, while after using Styrofoam waste the compressive strength is 179.50 kg/cm3 (5% Styrofoam), 162.72 kg/cm3 (10% Styrofoam), 142.15 kg/cm3 (15% Styrofoam), 103.94 kg/cm3 (20% Styrofoam), 80.32 kg/cm3 (25% Styrofoam), 64.71kg/cm3 (30% Styrofoam), and 59.95 kg/cm3 (35% Styrofoam). Based on the test results show that the addition of Styrofoam waste causes the compressive strength of concrete to decrease as the percentage of Styrofoam waste increases.

Abstract

The rampant damage to roads for urban roads and the lack of service providers in analyzing road damage are things that need to be considered. To overcome this, the role of historians is needed to convey road damage analysis methods according to applicable methods. In this activity, the Sriwijaya State Polytechnic service team together with partner PT. Sembilan Sembilan conducted an analysis of damage to the Pangeran Ratu Road section in Palembang City. From the survey results, it is known that the types of road damage according to the Bina Marga guidelines on the Pangeran Ratu Road section of Palembang consist of pothole damage, asphalt grain weathering, aggregate wear, longitudinal/transverse cracks, subsidence, and crocodile skin cracks. Several alternative road repairs for this type of damage can be in the form of patching aggregates and asphalt to dismantling damaged parts.
