Abstract

A pile foundation is needed to support the building, if the hard soil layer is very deep. The pile foundation functions to move or transfer the load above it (superstructure) to deeper soil layers. For this purpose, it is necessary to evaluate the capacity of a single pile and the capacity of a group of piles that are capable of carrying the load above them. Evaluation of pile capacity requires calendaring data in the form of field driving data which is carried out when the pile reaches hard ground with penetration and rebound values taken for 10 strokes. Based on calendaring data, single pole capacity analysis was carried out using several methods. The results of the bearing capacity analysis from one method are compared with other methods and their relationship with pile penetration. The capacity value of the pile group is calculated based on the pile efficiency. Most of the pile capacities show almost the same single pile capacity values, such as the Hiley method (666.16 kN), Navy-Mckay (752.14 kN), Janbu (440.91 kN), except that the Sanders method gives results that are much different from The value of other methods is 1138.28 kN, this could be because this method only considers the weight of the pile. The relationship between single pile capacity and pile penetration shows that the smaller the pile penetration value, the greater the pile capacity. This is obtained in all methods used, although with different calculation methods and method.

Abstract

Pondasi mesin merupakan elemen struktur yang digunakan untuk meneruskan beban dari mesin di atas pondasi ke dalam tanah. Selain memperhitungkan beban statis yang berasal dari berat mesin dan berat pondasi, perencanaan pondasi mesin juga harus memperhitungkan gaya dinamis yang dihasilkan oleh mesin. Pondasi jenis ini banyak digunakan untuk mesin industri, mesin bolak-balik, mesin rotasi, dan mesin lainnya. Dalam mendesain pondasi mesin, selain dapat menerima beban statis, pondasi mesin juga harus memenuhi persyaratan amplitudo dan frekuensi izin. Untuk menganalisis perbandingan respon dinamis yang terjadi pada saat mesin beroperasi pada kondisi tanah (lunak, sedang, dan keras), dimana memiliki pengaruh terhadap stabilitas pondasi tiang itu sendiri. Berdasarkan hal itu, diperlukan tiga parameter yaitu parameter tanah, mesin (berupa mesin pompa jenis submersible pumps), dan pondasi. Analisis yang digunakan pada pembahasan ini yaitu menggunakan metode analisis Novak. Dari hasil analisis yang didapatkan, Respon Dinamis berupa amplitudo yang paling besar terjadi pada tanah keras dengan getaran vertikal yaitu 3,545 x mm < amplitudo ijin yaitu 0,04 mm (mendekati batas ijin amplitudo) dan getaran horizontal sebesar 6,932 x mm < amplitudo ijin yaitu 0,07 mm. Selain itu, hasil beban dinamis yang diakibatkan saat mesin pompa beroperasi jauh lebih kecil dibandingkan dengan beban statis.

Abstract

The foundation is a substructure which functions to support the loads and forces caused by the superstructure (superstructure) to the soil layer which will carry these loads and forces. Deep foundations are usually used to obtain a large enough soil bearing capacity and if the depth of the hard soil is far below the ground surface. The aim of this task is to analyze the bearing capacity of pile foundations using sondir data, standard penetration test (SPT) data, as well as the finite element method using the plaxis program. The method used in this final assignment is by studying literature, then collecting the necessary data, and after that carrying out calculation analysis using existing methods. From the results of the calculations carried out, different results were obtained. Where for sondir data at point S1 obtained Qu =115.80 tons; at point S2 obtained Qu = 104.80 tons; at point S3 obtained Qu = 105.50 tons. Meanwhile, based on SPT data at point BH-01, Qu = 398.23 tons, and using the plaxis program Qu = 425 tons

Abstract

Research on the use of beach sand as a fine aggregate in concrete is due to the abundance of beach sand in the area. This research was carried out to analyze sand and find out how much compressive strength is produced when sand is treated without being washed with sand that is treated with washing, so that from this research the local community will know and can use it as a building material. The sand used is Pondok Permai Beach Sand, Pantai Cermin District, Serdang Bedagai Regency. The planned compressive strength of the concrete is 21.7 Mpa with 40 cylindrical test objects. Tests for compressive strength of samples were carried out at ages 7, 4, 21 and 28 days and each treatment was given 5 concrete samples. This research only focuses on beach sand concrete. The analysis results show that this beach sand is included in zone IV sand, namely sand with fine grains. The average compressive strength test results of concrete for sand not treated with washing and treated with washing at age 7 were the same, namely 16.22 Mpa. For compressive strength aged 14 days, concrete with sand that was not treated with washing produced a compressive strength of 15.58 Mpa, while concrete with sand that was treated with washing reached 17.44 Mpa. For compressive strength aged 21 days, concrete with sand that was not treated with washing produced a compressive strength of 16.10 Mpa, while concrete with sand that was treated with washing produced a compressive strength of 18.55 Mpa. In the compressive strength test aged 28 days, concrete with sand that was not treated with washing produced a compressive strength of 17.33 Mpa, while concrete with sand that was treated with washing produced a compressive strength of 19.55 Mpa. From the results of this research, the researchers concluded that the fineness of sand influences the compressive strength of concrete and washed sand can increase the compressive strength of concrete.

Abstract

Non-destructive tests are currently widely used in evaluating the quality of concrete installed in the field. One NDT is using the Ultrasonic Pulse Velocity (UPV) method. In general, the use of UPV in concrete is to estimate concrete strength, determine the homogeneity of concrete and detect concrete damage, for example the presence of voids or cracks. This research is intended to determine the accuracy of UPV test results in detecting concrete cracks at several variations in crack depth. In this research, the UPV tool validation process was carried out by making 1 type of test object. Namely 1 beam specimen for testing crack depth (UPV) with 6 variations of artificial cracks where the artificial cracks are made using plywood. Each sample has been treated so that it can describe the crack depth according to the existing plan. In testing, it was found that the estimated crack depth in variation I was 33.2 mm deep, variation II was 18.8 mm deep, variation III was 104.4 mm deep, variation IV was 115.8 mm deep, variation V was 24.4 mm deep and variation VI 159.3 mm deep. And the average accuracy is 13.60%. The smaller the wave travel time, the smaller the crack depth, the smaller the wave emission and the longer the wave path to detect cracks. which means that the accuracy of UPV crack depth testing tends to decrease with the unevenness of the concrete surface.

Abstract

An anchor is a steel element that is embedded in concrete when it is cast (cast in place) or installed later (post-installed) into concrete that has hardened and is used to distribute loads (tension and shear) acting on the concrete (SNI 2847:2019). The use of anchors in the world of construction is increasingly popular to help connect concrete structures. The installation of anchors has progressed from the initial anchors being installed before casting the concrete (cast in place), progressing to the anchors being installed after the concrete has hardened (post installed) by drilling. By drilling into concrete, installing and removing anchors becomes easier. Installation of cast-in-place anchors is generally used in the design of new construction, while post-installed anchor installation is generally used in old construction for repairs or retrofitting. Anchors have several variations including hed heax, L bolt and J bolt anchor variations, but it is not yet known which anchor variation has a greater bond strength value, what are the results of the comparison of bond strength values ​​for each variation of anchor and what are the differences in the anchor bond strength capacity for each variation? the anchor. With this research, it is hoped that we can find out the bond strength and bond stress values ​​for each variation of anchor so that the comparison of the bond strength of the anchor can answer the differences in capacity of each variation of the anchor as well. Research on the bond strength of anchors based on variations in anchor shape using the cast in place method shows that the bond strength value shown at the highest loading value is the type J anchor variation with an average load of 27,816 kN, the type L anchor variation with an average load of 26,971 kN and variations of the hex head type anchor with an average load of 12.85 kN. It can be concluded that the stress value is directly proportional to the loading value. The greater the loading value, the greater the bond stress value. The highest bond stress value is found in the type J anchor variation with an average bond stress value of 151,397 Mpa, in the L type anchor variation with an average bond stress value of 147,798 Mpa and in the hex head type anchor variation with an average bond stress value of 69.953 Mpa, so the bond stress is directly proportional to the loading value.

Abstract

The School Safety Zone (ZoSS) is designed to prevent accidents involving students when going to and from school. This research aims to determine the effect of inappropriate design and placement of markings and signs on ZoSS facilities based on visual observations of the speed of passing vehicles, crossing safety, and the level of conformity of ZoSS at the Alkaffah Binjai Waqf Foundation with established standards. The method used is to compare the results of field studies with the Directorate General of Land Transportation Standards, as well as using normal distribution statistical analysis (Z test). This research found that the DS value of the road is 0.45, which indicates that the road has a type C road service level. Speed the average number of vehicles passing on Jalan LetJend Jamin Ginting at the Alkaffah Binjai Wakaf Foundation ZoSS is: In the morning 35.44 km/hour (direction Binjai-Tanah Seribu) and 34.53 km/hour (direction Tanah Seribu-Binjai); In the afternoon 36.44 km/hour (direction Binjai-Tanah Seribu) and 38.91 km/hour (direction Tanah Seribu-Binjai). This speed still exceeds the permitted speed limit, namely 30 km/hour. The Z Test analysis of the characteristics of the waders in ZoSS shows that the calculated Z value (2.170) is greater than the Z table, which concludes that the waders in ZoSS are quite safe. However, the results of field observations showed that the signs were incomplete, their position was incorrect, and the road markings were damaged. These findings indicate that the ZoSS design in the field is not fully in accordance with the Directorate of Land Transportation Standards so it needs to be redesigned. The output of this research is a proposal to redesign ZoSS at the Alkaffah Binjai Waqf Foundation to be more in line with standards and improve safety for pedestrians, especially school students.

Abstract

A traffic accident event is very diverse both in terms of the process of occurrence and the level of accident. The number of accidents that occurred on the Jendral Sudirman road, Aek Batu Village, Torgamba District, resulted in many losses. On this basis, it is necessary to analyze the accident rate against the high number of accidents so that the accident rate can be known. The research method used in this research is a combined method which uses primary data and secondary data. Data from the Torgamba District Police, from 2019 to 2023, there were 378 traffic accident victims. Results of the percentage analysis of accident rates in the last 5 years, Light Injury (LR) victims were the highest in the accident rate with a percentage value of 62.17% with a total of 235 accident victims, then the number of Serious Injury (LB) victims was 25.93% with the number of victims was 98 accident victims, and the death toll (MD) was 11.9% with the number of victims being 45 accident victims. The results of the correlation coefficient analysis using SPSS to determine the correlation coefficient value for the accident level, it was obtained that the highest Pearson correlation value was found in victims of minor injuries. (LR) is (r) 0.920, which means it is perfectly correlated, with a significance value of 0.027, which means it has a significant relationship with the number of accident victims. Efforts that can be made to reduce the number of accidents are: providing education about traffic and strict sanctions to road users who violate traffic regulations and the installation of traffic signs must be in accordance with Decree of the Minister of Transportation Number 61 1993 concerning Traffic Signs
