Identifikasi Faktor Penyebab Penurunan Badan Jalan (Settlement) di Km. 128 Ruas Jalan Pekanbaru – Taluk Kuantan
Authors: Taufik Muhammad , Muhardi Muhardi , Yusa Muhamad 
Published: April 2023

Ruas jalan Pekanbaru Taluk Kuantan sebagian besar melewati daerah perbukitan dengan kemiringan lereng sekitar 30o – 70o. Sepanjang daerah perbukitan ini merupakan daerah rawan longsor namun sejauh ini longsor yang terjadi masih bisa segera diatasi karena volumenya tidak besar. Hanya saja ada satu titik lokasi yang selalu bermasalah yaitu di Km. 128. Pada lokasi ini selalu terjadi penurunan badan jalan dan miring ke arah sungai meskipun telah berulangkali diperbaiki. Usaha penanggulangan terakhir yang dilakukan oleh Kementrian Pekerjaan Umum dan Perumahan Rakyat, Direktora Jenderal Bina Marga Satuan Kerja Pelaksanaan Jalan Nasional Wilayah I Provinsi Riau adalah membangun lantai bertiang sepanjang 85 m dan dinding penahan tanah dengan fondasi tiang pancang sepanjang 120 m pada sisi arah sungai. Pada saat pelaksanaan, curah hujan cukup tinggi sehingga terjadi longsor yang mengakibatkan tiang-tiang pancang yang telah terpasang banyak yang bergeser sehingga perlu dilakukan penambahan titik pemancangan. Untuk mengetahui penyebab terjadinya penurunan badan jalan pada Km. 128 ini perlu diketahui struktur lapisan tanah bawah permukaan. Penelitian dilakukan dengan metode geolistrik resistivitas konfigurasi Wenner – Schlumberger. Metode ini dapat memetakan struktur lapisan tanah bawah permukaan secara horizontal dan vertikal dengan baik. Hasil interpretasi geolistrik menunjukkan pada kedalaman 4,5 m terdapat lapisan lempung lunak dengan kadar air tinggi setebal + 10,5 m. Lapisan ini sangat labil apabila di atasnya bertambah bebannya. Lapisan ini diduga menjadi penyebab terjadinya penurunan badan jalan. Lapisan ini mempunyai permeabilitas yang sangat rendah sehingga air terakumulasi di dalamnya dan dapat mendorong lapisan ini ke bawah. Lapisan ini juga diduga penyebab bergesernya tiang pancang yang telah dipancang. Di bawah lapisan tanah lempung lunak ini adalah tanah lempung kelanauan dan kepasiran dengan warna abu-abu dan sangat padat.

Transculturação de situações de ensino-aprendizagem: o caso da batucada afro-brasileira na escola secundária francesa
Authors: Guillot Gérald 
Published: April 2023

Este artigo tem como objetivo iniciar uma reflexão sobre o uso da música do Outro como recurso pedagógico na escola. Trata-se especificamente de uma tradição afro-brasileira, a batucada, na escola pública francesa. Porém, a análise dos saberes veiculados através de tal prática revela um diferencial importante com relação as suas referências endógenas. Tentar compreender um pouco mais esse fenômeno é o motivo desse trabalho. Após o exame das condições de transmissão da música afro-brasileira no Brasil e na França, utilizamos a Teoria Antropológica do Didático de Chevallard através o conceito de Transposição Didática. A elaboração de um modelo de transculturação das situações didáticas permite mostrar que esse uso — pedagógico e exógeno — da batucada provoca uma seria de derivações paradigmáticas. Uma delas interessa o professor francês, cuja responsabilidade pela transmissão dos saberes musicais se encontra exacerbada. Infelizmente, uma percepção cognitiva inadequada bloqueia o seu acesso a certos fundamentos musicais e atrapalha sua capacidade de transposição.

Published: April 2023

Corrugated web beams made of cold-formed steel components represent an economical solution for structures, offering high flexural capacity and deformation rigidity. For conventional corrugated web beams, made of thick plates for the flanges and thin sinusoidal steel sheets for the web, the elements can be joined by standard bolted end-plate connections. In the case of corrugated web beams made of thin-walled cold-formed steel components only, additional plates are required to accommodate the shape and position of the profiles. A large experimental program was carried out on corrugated web beams made of cold-formed steel elements. One of the objectives was to determine the capacity of these beams and the influence of several parameters on the response of the beam, but also very important were the end connections of these beams. The recordings obtained from the tests were used to validate a numerical model. Based on the validation of the numerical model, finite element analyses were performed to study four solutions for end connections to facilitate assembly, optimise the number of bolts, and increase the capacity and rigidity. Although the connection can be improved for assembling reasons with the presented solutions, the overall capacity is limited by the components subjected to compression that lose their stability.

Stress Path Behaviour and Friction Angle Transition Due to the Cyclic Loading Effects
Authors: Mohamad Habib Musa , Zainorabidin Adnan , Amaludin Adriana Erica 
Published: April 2023

In various aspects, peat soil is different from mineral soil. Peat is a biogenic deposit that emerged within the last 10,000 years, during the post-glacial (Holocene) era. Peat is a soft soil that is unable to support external loads without experiencing significant deformations. Tyre pressure from automobiles and/or aeroplane wheels on paved surfaces creates traffic load, which can manifest as static or dynamic types of loading. To resolve the problem with peat soils, a thorough understanding of the static and dynamic behaviour of peat is still required. Many people who live near regularly used highways feel traffic vibration, and it is important to comprehend the nature of this issue to make predictions about potential solutions to this problem. As such, this study aims to investigate the cohesion (c) and friction angle (φ) properties of peat soil after it has been subjected to cyclic stress. Monotonic triaxial tests are conducted to ascertain the initial shear strength characteristics of the soil. Cyclic triaxial tests are performed with half of their maximum deviator stress to simulate the behaviour of peat soil under various effective stresses and frequencies of loading that are applied with 100 number of cycles. After applying various numbers of cycles of dynamic loading, the post-cyclic monotonic shear strengths were subsequently evaluated. It has been noted that irregular behaviour tends to occur more frequently at higher frequencies, particularly between 2 and 3 Hz. With higher frequencies being applied, the reduction in cohesion and friction angle becomes more evident. Doi: 10.28991/CEJ-2023-09-04-010 Full Text: PDF
Impact of Plastic Waste on The Volumetric Characteristics and Resilient Modulus of Asphalt Concrete
Authors: Al-Tuwayyij Husham , Al-Mukaram Noorance , Musa Sarah S. 
Published: April 2023

Recently, the use of plastic in many products has led to a huge amount of plastic waste, which is typically difficult to treat and expensive to recycle. This problem has been considered by many researchers and environmental organizations as requiring serious considerations about recycling and reusing plastic waste in different fields, such as asphalt mixtures. In this paper, aggregate passing a 4.75-mm sieve was replaced by 5, 7, 9, and 11% of plastic bottles used for drinking purposes. The dry method was adopted in this work, and the changes in the mixture’s volumetric properties were investigated using the Marshall method. A repeated indirect tensile load test was also conducted to determine the mixture’s resilient modulus. Marshall’s stability, air voids, unit weight, flow, and voids in mineral aggregates were examined. The results were compared and analyzed with the base sample. It was observed that adding plastic decreased aggregate consumption and reduced the optimum asphalt content (OAC). Additionally, the volumetric properties of the mixture improved and its service life was extended after adding plastic. It was also observed that the value of the resilient modulus (RM) increased when the percentage of added plastic increased as well. Reuse of plastic in asphalt mixtures achieves the concept of an environmentally friendly solution in the transportation area because it reduces the amount of asphalt and aggregates and reduces the costs of recycling plastic. Moreover, the optimal plastic content in this paper was achieved at 11%. Doi: 10.28991/CEJ-2023-09-04-012 Full Text: PDF
Impact of Prior Knowledge about Autonomous Vehicles on the Public Attitude
Authors: Othman Kareem 
Published: April 2023

It is anticipated that AVs will offer multiple benefits, such as an improvement in the level of mobility, increasing the level of comfort, and reducing the number of traffic accidents. However, the public attitude is the main determinant factor that will face the deployment of AVs and in turn affect their implications. Over the last few years, there was a debate on the impact of the level of knowledge about AVs on public attitudes. While some studies show that people with higher levels of knowledge about AVs are the most optimistic, some other studies show that the public attitude moves in the negative with an increase in the level of knowledge. Thus, this study focuses exclusively on quantifying and understanding the impact of the level of knowledge and the public attitude in the US. A questionnaire survey was designed and conducted between June and November, 2022. A total of 5778 complete responses were received from all over the US and the analysis was conducted to estimate the public attitude and level of knowledge by region. The results show that there is a negative shift in public attitude with the increase in the level of knowledge about AVs. In addition, the results show that 1% increase in the level of knowledge about AVs is associated with 0.65%, 0.68%, and 2466 (USD) $ decrease in the level of interest, trust, and willingness to pay for AV and 0.56% increase in the level of concern about traveling in AVs. Moreover, the results are discussed in light of both the diffusion of innovation theory and the Gartner Hype curve. Doi: 10.28991/CEJ-2023-09-04-017 Full Text: PDF

Identifying risks in flood-prone areas is necessary to support risk management decisions. This research was conducted to establish a vulnerability model of flood hazards in the city of Pontianak. The model was based on the scoring and weighting of biophysical factors. The AHP method and logical formulations were used to establish the model. The result showed that the accuracy of the model used by AHP to determine the vulnerability of floods was 80% in Pontianak City. The accuracy of the model using logical formulations to determine the vulnerability level of a flood was 84%. The Kappa accuracy value in model 1 is 76.7%. The model of flood vulnerability explains that most of Pontianak City has a very high level of flood vulnerability, which is 31,440,568.8 m2 or 29.11% of the total research area of 108,003,319.8 m2. The vulnerable area is 29,945,485.7 m2 or 27.73%, and the less safe area is 22,126,936.3 m2 or 20.49%, with the safe area being 24,490,328.7 m2or 22.67% of the total area. This research contributes to the government to establish policies regarding flood management and urban development in the future, and as an effort to mitigate against flooding.

Published: April 2023

This paper reports an experimental study on the behavior and shear strength of concrete beams reinforced with longitudinal GFRP bars mixed with sea water. In order to evaluate how much concrete contributes to shear resistance, seven beams were tested in bending. Similar in size and concrete strength, the beams were longitudinally reinforced with glass fiber-reinforced polymer bars; however, they did not even have shear reinforcement. The beams, which measured 3,100 mm in length, 400 mm in depth, and 200 mm in width, were conducted and tested up to failure. The test variables were longitudinal reinforcement ratios (1.0, 1.4, and 2.0%), chopped fiber content (0, 0.5, 2, and 3 kg/m3), and mixing water type (freshwater and seawater). The test findings showed that increasing the reinforcement ratio increased the neutral-axis depth and allowed the formation of more closely spaced fractures while decreasing the loss of flexural stiffness after cracking. By increasing the area of concrete in compression, this in turn enhances the contribution of aggregate interlock as well as the contribution of uncracked concrete. Furthermore, increasing the reinforcement ratio improves the dowel action, which reduces the tensile stresses that are created in the concrete around it.

Published: April 2023

This research intends to analyze the optimal operation pattern for fulfilling the raw water demand, and it is conducted in the integrated cascade reservoir of Duriangkang-Muka Kuning, Batam City, Indonesia. However, Batam City is the economic center of the Riau Islands and absolutely needs enough raw water supplies to support its development. The need for raw water in Batam City is predicted to reach about 6,630.29 l/s in 2025. Due to the population growth that is estimated to reach about 1.8 million people in 2025 and the plan of Batam City development as an industry and tourism center, Batam City is faced with the condition that reservoir management becomes a very important thing for supporting the continuity of water supply. The methodology consists of collecting the supporting data, such as inflow, reservoir capacity curve, and data on water needs; then building the optimization model by determining the objective function and constraints of the integrated reservoir; and carrying out the optimization model by using linear programming and simulation models for the integrated reservoir operation. The result presents optimal reservoir operation of the integrated Duriangkang-Muka Kuning reservoirs. The reservoir operation consists of the boundary curve of upper and lower normal operation, the outflow for fulfilling the water need, and the rule of supply pumping from Duriangkang reservoir to Muka Kuning reservoir. It is hoped that the result can be used as a reference in operating the two reservoirs to fulfill the water needs of the Batam City population. Doi: 10.28991/CEJ-2023-09-04-07 Full Text: PDF
