Authors: Apriani Dyah Wahyu , Alfalik Dedi , Benny Sukmara Riyan
Published: August 2024

Penggunaan turap sebagai struktur penahan tanggul sungai perlu memperhitungkan pengaruh dari muka air aliran sungai untuk melihat bagaimana pengaruhnya terhadap stabilitas dari turap dalam hal ini terkait kedalaman pemancanngan, panjang turap dan crack momen yang terjadi. Selain itu perlu juga diperhatikan penggunaan tipe turap kantiliver dan turap diangkur sesuai ketinggian tanggul yang ditahan. Penelitian ini membahas bagaimana pengaruh perubahan elevasi muka air sungai terhadap stabilitas turap serta efektifitas tipe turap terhadap tinggi tanggul yang diperkuat dengan mengambil studi kasus Sungai Karang Mumus. Analisis hidrologi dan hidrolika dilakukan untuk mendapatkan penampang sungai dan ketinggian air untuk analisis. Skenario ketinggian air berdasarkan analisis hidrologi dan hidrolika dijalankan dalam analisis dan menghasilkan bahwa elevasi muka air sungai berpengaruh terhadap crack momen pada struktur turap dimana dapat berperan sebagai faktor yang dapat mengurangi terjadinya crack momen. Selain itu analisis juga menunjukkan pada elevasi tanggul yang sama penggunaan tipe turap diangkur akan menghasilkan panjang turap yang lebih kecil dan crack momen yang dihasilkan akibat gaya cenderung lebih kecil. Sebaliknya, apabila digunakan tipe turap kantilever maka panjang turap yang dibutuhkan lebih panjang dan crack momen yang dihasilkan cenderung lebih besar.

Published: August 2024

A job on a construction project can affect delays throughout the project. Every construction project has a specific plan and schedule for when to start when to finish, how to schedule, and how to provide resources. There should be no delays in implementation because they will result in increased project costs. However, there was a delay in the performance of the lecture building construction project with the Faculty of Engineering UPN "Veteran" East Java. The methods given in the discussion to determine the factors that influence the occurrence of delays are the Fault Tree Analysis (FTA) method and the Obtain Cut Set Method (MOCUS). Work items that experienced delays were structural, architectural, and MEP work. There are three top events known through FTA analysis, namely delays caused by design changes and wrong drawings, which are factors causing delays from service users. The dominant factor causing delays in structural work is the difference in elevation with elegant buildings and a need for more attention to structural safety. This problem occurs in the top event factor of service users. The service users referred to in scientific research are the owners and/or planning consultants. From the results of a quantitative Fault Tree analysis, the reliability value of the structural work is 0.861. In this case, the structural work experienced a delay of >10% with a Reliability value below 90%, so the contract was declared critical.

Authors: Citra Zel , Wibowo Paksi Dwiyanto , Malinda Yosie
Published: August 2024

The development of industrial construction requires adequate resources to avoid the failure and risk of the project. The resources required are materials (building materials), human resources (human resources), machines (equipment), capital (money), methods (methods of implementation), timing, and information on the implementation of the construction. According to data from the Central Statistical Agency (BPS), wages of labor in Indonesia of Rs. 2.89 million increased by 1.12% by 2022. In addition, the price of construction materials has also increased, such as steel, steel bones, concrete, and other construction materials. Especially steel price increases, starting in the second year of the pandemic, have risen about 30%–40%. Generally, the construction of factory buildings uses more steel profiles for the construction of warehouses—storage of raw materials or warehousing of production sites. This has a huge impact on the project budget that has been estimated prior to material price fluctuations. Therefore, the re-evaluation of the project budget in PT. XYZ, which has been estimated by the company at Rp. 219.5 billion, has a total budget change to Rp. 276.1 billion.

Published: August 2024

The foamed mortar (morbus) lightweight material consists of a mixture of sand, cement, water, and liquid foam (foam agent), which can improve the mechanical properties of clay soil and increase its bearing capacity. This research uses various variations of superplasticizer mixtures, namely by adding additional ingredients in the form of sikament-LN which will increase compressive strength by up to 40% at 28 days. This research needs to be carried out to determine the effect of sikament-LN on increasing the compressive strength of foamed mortar. The percentages of the sikament-LN mixture were 0.5%, 0.75%, 1%, and 1.25% with ages of 7, 14, and 28 days, each of which made 3 test objects in 4 variations of the mixture. The research results showed that the addition of sikament-LN to the 1.25% mixture did not meet the requirements because it produced a flowability of 23.5 cm and the mixture experienced a shrinkage of > 20% when placed in a cylindrical mold. All foamed mortar specimens experienced an average dry density increase of 1.994% at a curing age of 7 to 14 days and an average dry density increase of 4.044% at a curing age of 7 to 28 days. In a mixture of 0.5%, 0.75%, and 1%, at 28 days the maximum compressive strength value obtained was 841,667 kPa (more than the required 800 kPa). For the sikament-LN mixture, a maximum of 1% of the cement weight is recommended so that the hardening process occurs in the foamed mortar test object.

Published: August 2024

Expansive clay soils have swelling and shrinkage properties and somehow reduce the mechanical properties required for soils to be used in civil engineering works. One method to improve the soil is by mechanical stabilization, namely mixing expansive clay soil with sand material. The sand material used in this research varied by 7.5%, 15%, and 22.5% of the total dry weight of expansive clay. The results shows that changes in mechanical properties were observed from the compaction test and California Bearing Ratio (CBR) both for soaked or unsoaked test. Based on these variations, in the compaction test, the addition of sand variations increases the maximum dry unit weight value and generally reduces the optimum water content value. The same results were also seen in the soaked and unsoaked CBR tests. In the swelling potential test, the addition of sand material succeeded in reducing the swelling value in expansive clay soils.

According to the traffic accident data from the Traffic Accident Unit of the Tanjung Perak Port Police and the Traffic Accident Unit of the Dukuh Pakis Police in Surabaya City in 2020-2022, traffic accidents that occurred on the Bubutan Road - West Perak Road section experienced an increase in the number of traffic accidents. The total details in 2021 were 13 incidents, in 2022 there was an increase to 17 incidents, besides that, the material losses incurred in 2022 had the highest figure, which amounted to IDR 46,000,000. So it is necessary to analyze the accident-prone points on the road section. The method used are AEK (Accident Equivalent Number), IPA (Importance Performance Analysis) method, and calculation of free flow speed, traffic volume analysis, and side obstacle analysis. Based on the analysis of accident-prone areas using the AEK method, it is known that the upper control limit value is 36.07 where Jalan Perak Barat has an AEK value above the BKA value in 2021 of 37, then in 2022 of 40. Jalan Perak Barat has an average traffic volume of 434.47 smp / hour, with a moderate level of side obstacles, but has a free flow speed that exceeds the planned speed. One of the factors causing traffic accidents on Jalan Perak Barat is the driver of a vehicle traveling at high speed, so rumble strip planning and road facility rejuvenation are recommended.
