Abstract

AbstractSide friction are side-road activities that have a significant effect. The high level of roadside activity affects the capacity and performance of roads in an urban area, with the cause of the growing and developing population activity every year. This study uses a method that is guided by the Guidelines for Indonesia's Road Capacity (PKJI 2014).  In this study, the value of side friction on Teuku Umar's road (Advent Hospital – Koga Market) was 567 skr / hour (medium class), while on Imam Bonjol's road (Langkapura) it was 158skr / hour (low class). For the Teuku Umar's road there was a decrease in capacity by 4%, while on the Imam Bonjol's road there was a decrease in capacity by 1%. The cause of congestion on Teuku Umar's road is due to vehicles turning around and vehicles coming in and out of the road, while on Imam Bonjol's road it is due to vehicles going in and out of the road. So that the alternative solution to overcome traffic jams on Teuku Umar's road (Koga market - RS Advent) is to curb motorists who stop carelessly on the road, and set the traffic signs that prohibited from stopping on each side of the road, while on Imam Bonjol's road (langkapura– kemiling) it is necessary to monitor vehicles entering / exiting the alley, because it has the potential to cause long traffic jams. Keywords : Side friction, Guidelines for Indonesia's Road Capacity, Traffic.

Abstract

This research was conducted to determine the impact of the areas where El Nino and La Nina were the most dominant. The data used in this study are daily rainfall data in 5 rain stations located in East Lampung. Data length from 1989 to 2018 at each station, this data was taken from the Mesuji River Basin - Sekampung (BBWSMS). This modeling is carried out using a data length of 30 years for a data term of 10957.By using observational data and applying it in 2 programs, namely the Fast Fourier Transform (FFT) and the Lomb Periodogram, it produces values that can be graphed for the spectrum of each of the 5 rain station areas, namely Jepara Lake, Labuhan Ratu, Taman Negeri, Kota Raman and Sri Gading. From the results, it can be seen which areas are predominantly affected by El Nino and La Nina. Based on the results of the two programs, both show that the rain station in the Lake Jepara area experiences more dominant El Nino and La Nina influences. Keywords: El Nino, La Nina, rain station, rainfall, Fast Fourier Transform, Lomb Periodogram

Abstract

Subgradeis the most important part to be used as the focus and support of all construction loads that are on it. If the subgrade is clay soil that has a low carrying capacity and is very sensitive to moisture content, then nearby buildings will often suffer damage, such as land located in Marga Kaya Village. In this study using the method of mixing native soil with stabilization material in the form of uniform sand derived from Mount Sugih with a mixture variation of 5%, 10% and 15% of the dry weight of the soil. The test results showed cbr unsoaked and soaked maximum occurred in sand mixture 15% with CBR Unsoaked value of 13.2% and CBR Soaked with a value of 2.9%. Road pavement thickness on CBR Unsoaked and Soaked efficiently on sand mixture 15% with thickness D1 = 2.75 cm, D2 = 20 and D3 = 10 cm, and CBR Soaked with thickness D1 = 8.75 cm, D2 = 20 cm and D3 = 10 cm. The value of swelling decreased from 11.4% to 7.4% in the addition of uniform sand by 15%. DDT value is influenced by cbr value the greater cbr value then DDT will increase.

Abstract

In testing reinforced concrete beams strengthened with 4 layers of GFRP can increase the maximum load up to 112%. The test can be done by modeling using finite element based software.The beam that is modeled has a dimension of 1,7 m long, 15 cm wide and 15 cm high with 4 layers of 1,3 mm/layer GFRP. The beams that are modeled are only a quarter section because of symmetrical geometry and loading.The percentage difference between the results of modeling and experimental tests on normal beams is 1,49% for deflection in the middle span. The crack that occurs in normal beams in modeling and experimental shows the same crack pattern, which is flexural crack. The percentage difference between modeling and experimental tests on the strengthened beam is 21,81% for the deflection in the middle span. In experimental and modeling tests, the applied GFRP undergoes debonding before the concrete compressive strain reaches its ultimate strain.Keywords: Concrete, GFRP, debonding, modeling

Abstract

Penelitian ini membahas pemodelan balok beton bertulang yang diperkuat material wiremesh, yang dianalisis menggunakan finite element analysis (FEA) software. Pemodelan yang dilakukan mengacu pada studi eksperimental terdahulu. Balok yang dimodelkan hanya seperempat bagian untuk mempercepat proses analisis. Interaksi antara beton dan tulangan dimodelkan sebagai embedded region dan interaksi antara beton dan material wiremesh dimodelkan sebagai tie constraint. Persentase selisih antara pemodelan dan studi eksperimental untuk balok tanpa perkuatan adalah 0,76% untuk lendutan, 10,88% untuk regangan beton bagian atas, dan 13,70% untuk regangan beton bagian samping. Persentase selisih antara pemodelan dan studi eksperimental untuk balok dengan perkuatan wiremesh adalah 18,47% untuk lendutan, 2,09% untuk regangan beton bagian atas, dan untuk 1,93% regangan beton bagian samping. Adanya perbedaan nilai lendutan dan regangan secara umum disebabkan olehinteraksi antar permukaan komponen pada pemodelan dimodelkan terikat sempurna dan material beton pada pemodelan bersifat homogen.
