Abstract

Kondisi tanah yang berada pada lahan yang miring dan tidak rata berpotensi membahayakan bangunan yang berada di sekitar lahan tanah tersebut, terlebih bilakemiringan lahan cukup curam. Oleh karena itu perlu dilakukan upaya penanggulangan untuk mengatasipermasalahan tersebut, salah satunya dengan cara membuat talud dinding penahan tanah. Sistemdinding penahan tanah berundak, dapat menjadi salah satu cara untuk mengurangikecuraman sudut lereng sehinggameminimalisir terjadinya longsor. Kondisi demikian juga dilakukan pada lereng yang terletak di sebelah bangunan Mushola Baitussalam, Dusun Tegalsale Desa Jembrak,Kecamatan Pabelan Kabupaten Semarang. Talud dinding penahan tanah bangunan MusholaBaitussalam berada pada elevasi tanah yang lebih tinggi dari pada jalan raya. Selain itu, terdapat parit, selokan dengan aliran air yang cukup deras. Oleh karena itu diperlukan dinding penahan tanah tambahan untuk mencegah longsor. Kemungkinan adanya gerusan akibat aliran air paritselokan cukup berbahaya bagi struktur bangunan mushola sehingga memerlukan penanganansegera agar struktur bangunan mushola terhindar dari keruntuhan akibat adanya gerusan air danketidakstabilan lereng tanah.Tim Pengabdian kepada Masyarakat Departemen Teknik Sipil UNDIP membantu masyarakat menanganipermasalahan tersebut dengan memberikan pendampingan pembuatan talud dinding penahantanah yang sesuai dengan kondisi bangunan mushola Baitussalam.

Abstract

Kecamatan Tembalang, Semarang merupakan salah satu kawasan yang memiliki tingkat pembangunan dan pengembangan infrastruktur yang cepat tetapi memiliki tantangan yaitu kondisi topografi yang cenderung memiliki kemiringan lereng yang curam. Keberadaan bangunan pada suatu lereng perlu diwaspadai dikarenakan resiko terjadinya kelongsoran. Kondisi bahaya kelongsoran seperti ini dapat dianalisis menggunakan program PLAXIS. PLAXIS merupakan suatu program elemen hingga yang dikembangkan untuk analisis deformasi, stabilitas dan aliran air tanah dalam rekayasa geoteknik. Hal ini menyebabkan program ini menjadi salah satu program yang sangat menguntungkan untuk dipelajari dan dikuasai oleh Mahasiswa Teknik Sipil UNDIP. Kondisi “study from home” yang disebabkan mewabahnya virus COVID-19, membatasi mahasiswa dalam mengembangkan kemampuan dan memperoleh ilmu tambahan. Oleh karena itu, Tim Pengabdian masyarakat Teknik Sipil UNDIP mengadakan pelatihan secara online mengenai program PLAXIS untuk analisis bahaya kelongsoran pada lereng. Pelatihan dilaksanakan secara daring dengan kelas online pada Ms. Teams. Pelatihan diisi dengan pemberian materi pengenalan, video tutorial, dan video conference sebagai media diskusi dan tanya jawab. Pada hari terakhir juga diberikan form evaluasi sebagai bahan pengembangan pelaksanaan pengabdian masyarakat selanjutnya. Dengan adanya pelatihan tahap pertama sebagai pengenalan terhadap program PLAXIS ini, dapat sebagai pintu gerbang bagi peserta untuk memodelkan dan menganalisis pekerjaan sipil dalam analisa geoteknik dengan PLAXIS. Sehingga, memudahkan peserta dalam memahami penggunaan program PLAXIS terutama dalam pemodelan stabilitas lereng dengan perkuatan. Selain itu, kegiatan pelaksanaan pelatihan secara online ini dapat membantu mengatasi kesulitan peserta mahasiswa dalam mengembangkan potensi diri selama masa study from home.

Abstract

The challenge of construction supply chain management is to maintain supply and demand in the supply chain flow and ensure a sustainable supply chain in the framework of lean construction. This challenge must be captured as part of the solution of the development of the rapidly growing construction industry. At present a sustainableSCOR on the Supply Chain Operations Reference (SCOR) version 12.0 has been developed. SustainableSCOR is a concept of a sustainable supply chain performance measurement approach by considering environmental aspects. The aim of this study is to adopt a supply chain performance measurement model in the sustainable construction of SCOR 12.0. The research method adopts standards, categories, and matrices in sustainableSCOR to a constructionally validated definition to academics and practitioners. The discussion of the supply chain continues with the calculation of each matrix. The results showed that all sustainableSCOR categories, namely materials, recycled inputs, recovered inputs, energy, water, emissions, and waste can be adopted to measure sustainable supply chain performance in construction. The adoption of this performance measurement needs to be detailed into one of the construction materials, in this study is steel material.

Abstract

Clay shale is a material that has the characteristic of being easily weathered if it is continuously exposed to the air. Based on this reason, further testing is needed for clay shale material to analyze the material characteristics, one of which is using a hydrometer test. In the hydrometer test, an anticoagulant breaks down the particles. Still, when the test was carried out by various laboratories with different types of samples, it would produce varying test results. This study aims to determine the effect of anticoagulant substances and their concentration on clay shale dispersion in the hydrometer test. The material used was clay shale from the Meteseh, Tembalang District, Semarang. This research method used was a hydrometer test based on British Standard 1377 Part 2 1990 and ASTM D7928-17 using seven anticoagulant agents. The results of the study using the British Standard 1377 Part 2 method showed that sodium polyphosphate, sodium pyrophosphate, and sodium hexametaphosphate were most influential in dispersing clay shale particles, which were characterized by a higher passing percentage of 0.042 mm and 0.002 mm when compared to other anticoagulants. Meanwhile, Calgon, sodium carbonate, sodium tripolyphosphate, and sodium silicate did not significantly affect the clay shale dispersion, indicated by the percentage that passed the sieve, which was not very high. Based on the British Standard 1377 Part 2 1990 and ASTM D7928-17 methods, the most optimum concentration in dispersing clay shale for sodium polyphosphate and sodium pyrophosphate is 5%, while for sodium hexametaphosphate is 6%.

Abstract

In the simple buildings, shallow foundations can be used to support the construction above them. This shallow foundation has various types, including the type of footplate which can be calculated using the Terzaghi equation. In the Terzaghi equation, it requires dimension parameters of the footing and soil material parameters such as cohesion and soil volume weight which requires laboratory testing to obtain it. Meanwhile, Schmertmann provides an equation to obtain the Terzaghi bearing capacity factor in the form of Nq and Nγ by using the Cone Penetration Test (CPT). This bearing capacity factor value can be used to calculate the bearing capacity using the Terzaghi Equation. In addition, Schmertmann also provides an equation to directly calculate the bearing capacity value based on CPT data. Based on this problem, this study analyzes the bearing capacity of various footplate dimensions using the Schmertmann approach. The study took place in the Argoboga, Salatiga which the type of soil based on the CPT test value generally is sandy soil. The results show that the bearing capacity calculated by the Nq correlation method is greater than the Nγ correlation method and the direct correlation method. In addition, the greater the difference between the dimensions and the depth of the foundation, the greater the deviation of the bearing capacity results between each method.

Abstract

Outcome Based Education (OBE) is a learning method that focuses on outcomes in a learning process. In the field of engineering, the delivery of lecture materials coupled with the achievement of targets for outcomes is a challenge, especially when it comes to technology applications. This is because the application of technology requires real examples, so that the students can have a comprehensive picture and understanding. This study was carried out on the Internet of Things (IoT) course at Undergraduate Program in Civil Engineering, Faculty of Engineering. This course discusses the basics of applying IPTEKS (Science, Technology and Arts) tools that can be utilized in the field of Civil Engineering, especially in the current Industrial Revolution 4.0. This research was intended to evaluate the OBE implementation, in terms of student participation and level of understanding of students. Observations were made during one semester by observing the results of student evaluations and the feedback received by the lecturers. The evaluation was carried out qualitatively and quantitatively based on the course learning outcomes (CLO). The results showed that all students actively participate in the learning process using this OBE method. The high level of material understanding was indicated by the achievement of a 100% passing rate, but there were still two students who have not fulfilled two CLOs. Therefore, continuous improvement efforts are still needed in implementing OBE for students, so that all students can fulfill all CLOs in Internet of Things courses.

Abstract

The consolidation analysis becomes complicated when conducted on varying layers of soil. To simplify and solve these problems, designers often employ Finite Element Method (FEM) modeling, a widely used technique for analyzing geotechnical issues. However, many limitations associated with this method can lead to model results that do not accurately reflect actual conditions. Consequently, the consolidation settlement analysis during design may differ from actual conditions in the field. This study examines the influence of consolidation parameters and explores how to analyze consolidation settlement using FEM for practical applications. Specifically, consolidation settlement was assessed on the Semarang-Demak toll road, which utilizes a Preloading-PVD improvement method across nine Stationing (STA) locations with varying soil layers. Numerical modeling was performed using Midas GTS NX 2021 (V.1.1) and was validated against instrumentation observation results, Settlement Plate. An evaluation using the back analysis method was conducted to investigate the impact of consolidation parameters on the accuracy of the final consolidation settlement results. The consolidation parameters reviewed are the compression index (Cc) and recompression index (Cr). The findings indicate that the Cc and Cr significantly influence the final consolidation settlement. By optimizing these consolidation parameter values, the deviation between observed results and numerical modeling for final consolidation settlement is reduced to less than 1%. Additionally, this research derived empirical equations for calculating consolidation parameters based on the Liquid Limit, a fundamental laboratory test. The results of this study can be proposed to analyze consolidation settlement using FEM modeling for soft clay to stiff clay, providing valuable insights for practical applications.

Abstract

In 2017, the National Centre for Earthquake Studies of Indonesia released the distribution of 25 shallow crustal fault lines throughout the island of Java in Indonesia and four of them (Semarang, Demak, Rawapening and Weleri fault lines) are located around the city of Semarang. The presence of four shallow crustal fault earthquake sources, has led to the need to understand the potential earthquake hazards of Semarang through the development of earthquake-microzoning maps. Earthquake-microzoning maps of Semarang should be developed with reference to the Indonesian earthquake hazard maps and based on the deterministic and probabilistic seismic hazard approaches. Through the development of earthquake-microzoning maps, it is possible to estimate the areas with the highest and lowest surface-shaking (peak ground acceleration). The earthquake-microzoning maps based on the Semarang and Demak fault earthquake scenarios provide a preliminary indication that buildings constructed using the Indonesian Seismic Code (SNI 1726:2002) will experience stronger surface-shaking if the earthquake magnitude from both sources is at least M5.5. The results of the analysis for the creation of earthquake-microzoning maps based on the Rawapening and Weleri fault earthquake scenarios provide a preliminary indication that buildings constructed using SNI 1726:2002 are expected to experience slightly weaker ground-shaking if the earthquake magnitude from both sources reaches a maximum of M6.5. All buildings constructed in this area using SNI 1726:2012 and SNI 1726:2019 are expected to experience weaker surface-shaking due to the four earthquake source scenarios with a maximum magnitude of M6.5.
