Abstract

Palembang is a city that often experiences flooding which is detrimental to the community.. Flooding can occur for various reasons, including drainage systems that often do not function properly, a lack of water absorption areas in large cities, and rivers that can no longer accommodate the volume of water during heavy rain. One of the rivers in the city of Palembang, namely the Bendung River, is located in the Kemuning District. The problem with this river is that it has many tributaries contributing to its main flow. The purpose of this research is to analyze hydrology, with rainfall data analyzed using normal distribution, log-normal, log-Pearson III, and Gumbel methods. The results of the research conducted on the Air Bayas River showed the flood discharge values for different return periods: 2-year return period: 9.317 m³/s, 5-year return period: 10.552 m³/s, 10-year return period: 11.364 m³/s, 25-year return period: 12.386 m³/s, 50-year return period: 13.147 m³/s, 100-year return period: 13.910 m³/s. The ideal dimensions of the channel with a depth of 2.35 m and a planned width of 6 m are necessary to accommodate the flood discharge without overflowing.

Abstract

One of the largest cities, because it is the center of social and economic activities, is Palembang City. The area of ​​Palembang City is around 400.61 km², consisting of 16 sub-districts and 107 villages. In this area, heavy rain has occurred which has caused flooding in this area, especially on Jalan Pipa Raja, Palembang City. One of the causes of flooding in Palembang is due to low land conditions and high tides of the Musi River. In the role of flood control, the lack of public awareness in maintaining the drainage system also worsens waterlogging. Flood control requires extensive and specific engineering knowledge. The structural method used in this study is the retention pond method. The retention pond on Jalan Pipa Jaya in Kemuning District has a capacity of around 328.8 m3/hour. Data for this study were obtained from literature studies, primary data, and secondary data. The results of the study that have been carried out indicate that in modeling using HEC-HMS, it is known that the Pipa Jaya retention pond can accommodate a peak inlet discharge of 161.3 m3/s, with a decrease to 29.7 m3/s.

Abstract

Geopolymer concrete is an environmentally friendly alternative to conventional concrete because it has the potential to reduce carbon emissions. Rice husk ash, an agricultural waste, serves as a source of silica and alumina in the geopolymerization process. This study aims to determine the compressive strength value of geopolymer concrete in each variation and the use of alkali activator ratios between Na2SiO3 and NaOH with ratios of 1:2, 2:2, and 3:2. In the study of the compressive strength characteristics of engineering concrete, the experimental method was used. Based on the study of the compressive strength characteristics of geopolymer concrete made from rice husk ash, normal concrete at the age of 28 days has a compressive strength of 368 kg/cm2, while in the 1st geopolymer concrete at the age of 28 days, a compressive strength of 349 kg/cm2 is obtained. This shows that the compressive strength of the 1st geopolymer concrete has decreased by 5% from normal concrete, in the 2nd geopolymer concrete at the age of 28 days, a compressive strength value of 475 kg/cm2 was obtained, which means that the compressive strength of the 2nd geopolymer concrete has increased by 29% from the compressive strength of normal concrete. This study identified the optimal compressive strength of geopolymer concrete, specifically noting that the second geopolymer concrete reached a value of 475 kg/cm².

Abstract

In its development, many new concrete modifications were found, such as lightweight concrete, fiber concrete, polymer concrete, high-strength concrete and ultra-high-strength concrete. Epoxy resin can accelerate the hardening process of concrete because epoxy itself generates heat so that it helps accelerate hardening. In previous studies, the addition of areca nut shell fiber and 0.8% epoxy resin can increase the split tensile strength of concrete. Based on the description above, it is necessary to conduct research on the split tensile strength of concrete that combines a mixture of pineapple leaf fiber and epoxy resin. So this research uses pineapple leaf fiber and epoxy resin. Pineapple leaf fiber and epoxy resin are expected to be strength-enhancing materials that can produce concrete with more optimal split tensile strength.  The purpose of this study was to determine the effect of the addition of epoxy resin and the percentage variation of pineapple leaf fiber on the split tensile strength of concrete and its comparison with normal concrete and to determine the percentage level of the addition of the most optimum pineapple leaf fiber to produce the maximum concrete split tensile strength test value among the planned variations. The method used in this research is experimental. From the results of the average split tensile strength test at 28 days, the epoxy resin variation of 0.8% achieved a strength of 2.87 MPa, the 0.15% variation achieved 2.37 MPa, and the 0.5% variation achieved 2.47 MPa

Abstract

Economic growth that increases the traffic load on national roads requires these roads to have decent, safe and comfortable services. Landslide was occurred on the Sekayu-Mangun Jaya STA 127+350 road section which disrupted traffic activity. This occurrence caused the major road to shift sideways and deteriorate, rendering the route's service capacity insufficient. The road section has been repaired and is planned to use soil retaining wall reinforcement as a countermeasure. This study aims to determine the slope stability of the Sekayu-Mangun Jaya road before and after reinforcement is carried out. Slope stability analysis was performed by empirical methods using infinite slope theory and the finite element method using the Plaxis program. The calculation results show that the safety factor of the slope before the retaining wall is installed at BH-01 is 0.9. This value falls under the category of unstable slope. The safety factor at the BH-02 location was obtained at 1.3 in the moderate stability category. Slope stability after strengthening with the installation of embankments and retaining walls shows an increase in the safety factor at BH-01 to 2.59. After the slope reinforcement was carried out, the slope deformation decreased significantly to 1.5 m. The results implicated that with slope reinforcement, slope stability increases and the possibility of landslides decreases.

Abstract

Penerapan BIM pada proyek Pembangunan Jalan Tol merupakan upaya Kementrian PUPR dalam peningkatan daya produktifitas dan daya guna perencanaan dan pembangunan proyek konstruksi jalan bebas hambatan melalui implementasi Information and Comunication Technology (ICT). Melalui Badan Pengatur Jalan Tol (BPJT) memberikan tugas kepada Badan Usaha Jalan Tol (BUJT) untuk menerapkan BIM pada Pembangunan Jalan Tol Indralaya – Prabumulih. Dengan BIM diharapkan akan meminimalisir kesalah dalam perhitungan QTO yang mengakibatkan kesalahan dalam penentuan biaya proyek. Metode BIM dilakukan dengan menggunakan software pendukung yaitu Autodesk Revit untuk melakukan pemodelan 3D dan 5D (QTO) yang nantinya hasil perhitungan volume metode BIM akan di bandingkan dengan perhitungan volume metode konvensional. Studi kasus dilakukan pada Box Culvert STA. 0+126 pada Pembangunan Jalan Tol Indralaya – Prabumulih. Berdasarkan hasil penelitian didapatkan perbedaan volume secara keseluruhan sebesar 0,03% dimana perhitungan dengan Autodesk Revit lebih besar dibandingkan perhitungan konvensional. Persentase perbedaan pada pasangan batu kosong (Blinding Stone) sebesar 0,01%, beton struktur kelas E sebesar 0,01%, batang baja tulangan BJTD-40 sebesar 0,02%, struktur beton kelas C-2 dan urugan material berbutir (granular backfill) sebesar 0%. BIM dengan Autodesk Revit dapat melakukan perhitungan QTO secara otomatis yang sudah terintegrasi dengan desain 3Dnya, sehingga meningkatkan ketelitian dalam penentuan Rencana Anggaran Biaya (RAB).
