Abstract

Beton merupakan material konstruksi yang banyak digunakan, namun dampak lingkungan yang ditimbulkan, terutama dalam hal emisi CO?, mendorong pencarian alternatif yang lebih ramah lingkungan. Beton geopolimer, yang memanfaatkan fly ash dan abu sekam padi sebagai bahan pengikat, dapat menjadi solusi yang menjanjikan untuk menggantikan beton konvensional. Penelitian ini bertujuan untuk mengkaji pengaruh variasi komposisi fly ash dan abu sekam padi terhadap sifat mekanis dan workability beton geopolimer. Variasi campuran yang digunakan terdiri dari proporsi fly ash dan abu sekam padi sebesar 100:0, 80:20, 70:30, dan 50:50, dengan larutan alkali aktivator NaOH 12M dan Na?SiO? dengan rasio 1:2,5. Hasil penelitian menunjukkan bahwa campuran dengan 100% fly ash menghasilkan kuat tekan tertinggi, yaitu 23,13 MPa, dan nilai slump 8,0 cm, yang mengindikasikan kinerja beton yang baik dalam hal kekuatan dan workability. Sebaliknya, peningkatan proporsi abu sekam padi menyebabkan penurunan kuat tekan dan slump, dengan nilai terendah pada campuran 50% abu sekam padi, yang menghasilkan kuat tekan 17,20 MPa dan nilai slump 5,5 cm. Berdasarkan hasil ini, dapat disimpulkan bahwa fly ash tetap menjadi bahan pengikat utama yang lebih baik untuk beton geopolimer, sementara abu sekam padi dapat digunakan dalam proporsi terkendali untuk mendukung keberlanjutan lingkungan. Penelitian lanjutan disarankan untuk mengeksplorasi penggunaan bahan tambahan lainnya dan melakukan analisis mikrostruktur untuk meningkatkan performa beton geopolimer.

Abstract

Inadequacies in the conceptualization and assessment of construction scheduling frameworks can disrupt the epistemic continuity of project execution, thereby undermining procedural coherence and operational efficiency. Accurate and detailed material quantity planning is essential to ensure precise resource forecasting and the development of efficient and reliable construction schedules. This research investigates the role of methodological selection in the accuracy and efficiency of construction planning, with a particular emphasis on material quantification and scheduling outcomes through this comparative framework. The methodological approach undertaken in this study involves quantity surveying practices through the application of two modelling-based techniques, namely CAD-Revit and CAD-Conventional. For construction-shop drawing documentation as the primary data source, material quantities derived from each method serve as the basis for schedule development. This process culminates in the integration of 4D Building Information Modelling to facilitate the temporal visualisation of construction sequences, which supports a more comprehensive evaluation of the implications associated with each quantity derivation method on the accuracy of project planning. The comparative analysis of material quantities derived from the two methods revealed significant fluctuations, with the CAD-Revit approach demonstrating greater efficiency in material usage. This variation was further reflected in the scheduling outcomes, where the 4D BIM methodology indicated divergent timelines for the completion of structural component progress across different floors.

Abstract

This study aims to analyze the development of supporting infrastructure for Asol Water Tourism in the Haruku Island area, Maluku, particularly in Negeri Oma, which possesses beautiful natural potential but is constrained by limited tourism facilities and infrastructure. The Analytical Hierarchy Process (AHP) method was used to determine priority development criteria through analysis of pre-construction, construction, and post-construction aspects. The results show that the dominant criterion in the pre-construction aspect is construction engineering with consideration of building structure and the environment, with a priority weight of 0.578. In the construction aspect, the dominant criterion is the application of project control principles related to time, quality, and cost, with a weight of 0.091. Meanwhile, in the post-construction aspect, the dominant criterion is synergy through the involvement of communities, the private sector, and universities to achieve operational independence, with a weight of 0.1156. In conclusion, these three aspects are expected to significantly contribute to the development of high-quality and environmentally conscious tourism facilities and infrastructure for Asol Water Tourism.

Abstract

Infrastructure development is one of the main indicators in supporting city development, especially in metropolitan areas such as Surabaya. One of the strategic projects being designed is the construction of a pedestrian tunnel that will connect the Joyoboyo Intermodal Terminal (TIJ) with the Surabaya Zoo (KBS). This study aims to optimize the cost and completion time of the project through a case study of the construction of a pedestrian tunnel between TIJ and KBS. Based on the contract's provisions, this project is scheduled to be completed within 156 calendar days, starting on May 30 2024, and ending on November 21, 2024. As an effort to optimize the cost and duration of project implementation, the Time Cost Trade Off (TCTO) approach is used. Through the application of this method, the results obtained that the addition of working time (overtime) for 3 hours per day on the work item of reinforced concrete walls with a thickness of 60 cm and concrete quality Fc'35 MPa (PC 450) is quite effective in accelerating project completion from 156 days to 145 days. In addition, the optimum cost generated is Rp14,116,469,946.62, which means a cost saving of Rp43,510,269.42 compared to the normal cost. From the analysis results, the project time efficiency is 0.31%.

Abstract

Penelitian ini menganalisis daya dukung aksial dan penurunan pondasi spun pile berdiameter 60 cm untuk Gedung Rawat Inap Tower-1 RS Haji Medan, menggunakan uji pembebanan statis (static load test) dan pemodelan elemen hingga (FEM) dengan PLAXIS 3D. Data lapangan dari Uji Penetrasi Standar (SPT) dan cyclic loading test dibandingkan dengan simulasi numerik menggunakan model Mohr-Coulomb dan Hardening Soil. Perhitungan empiris berbasis data SPT (metode O’Neil & Reese) menghasilkan kapasitas ultimit (Qult) 204,24 ton, sedangkan interpretasi uji pembebanan (metode Davisson, Mazurkiewicz, dan Chin) menunjukkan nilai lebih tinggi (390–476 ton), mengonfirmasi sifat konservatif prediksi berbasis SPT. Faktor keamanan (2,43–2,97) memenuhi standar ASTM D1143. Simulasi PLAXIS 3D secara akurat mereplikasi penurunan yang diukur di lapangan, dengan deviasi maksimal <5%. Model Hardening Soil memberikan kesesuaian lebih baik dengan hasil loading test (penurunan 6,66 mm pada beban 320 ton) dengan mempertimbangkan nonlinieritas tanah. Perhitungan penurunan elastis (2,1 mm untuk tiang tunggal; 5,9 mm untuk kelompok tiang) tetap dalam batas toleransi (25 mm). Rekomendasi meliputi optimasi panjang tiang berdasarkan stratigrafi SPT dan penggunaan model Hardening Soil untuk proyek dengan cyclic loads. Pendekatan terpadu ini meningkatkan desain pondasi dalam yang ekonomis dan aman untuk struktur bertingkat tinggi di wilayah perkotaan dengan keterbatasan lahan.

Abstract

Penelitian Pada analisis pondasi, besarnya daya dukung dan penurunan yang terjadi merupakan dua kriteria yang sangat penting. Pondasi wajib memiliki daya dukung yang mampu memikul beban diatasnya, sehingga sistem tranfer beban ke tanah dapat berjalan dengan tetap mengontrol terhadap penurunan ijin untuk menjaga kestabilan konstruksi di atasnya. Analisis ini bermanfaat untuk menghitung besarnya daya dukung dan penurunan yang terjadi pada pondasi spun pile proyek Gedung Rawat Inap Tower-1 RS Haji Medan, secara empiris dengan metode elemen hingga menggunakan aplikasi PLAXIS 3D dengan jenis tanah Mohr-Coulomb dan Hardening Soil Dari analisis yang telah dilakukan, daya dukung ultimate spun pile berdasarkan data SPT dengan menggunakan persamaan O’Neil dan Reese adalah 165,42 ton sedangkan menggunakan hasil interpretasi loading test dengan metode Davisson memberikan nilai 330 ton, metode Mazurkiewich 430 ton dan metode Chin 380 ton. Untuk besar penurunan spun pile tunggal, secara analitis dengan hasil loading test Aksial di lapangan menghasilkan besar penurunan 8,45 mm, analisis berdasarkan FEM PLAXIS 3D Mohr-Coulomb besar penurunan 10,99 mm dan Hardening Soil besar penurunan 9,26 mm. Kesimpulan dari analisis bahwa nilai keamanan yang digunakan saat desain dan analisis penurunan yang paling mendekati hasil di lapangan adalah analisis dengan PLAXIS 3D dengan jenis permodelan Hardening Soil.

Abstract

Indonesia, as an agrarian country, heavily relies on the availability of water for irrigation, raw water supply, and electricity generation to support industrial growth. One of the government’s efforts to ensure water availability is the construction of dams, including the Cibeet Dam, which serves to reduce flooding, provide raw water, support irrigation, and generate electricity. A crucial component of a dam is the spillway, which must be capable of accommodating excess water, especially during extreme flood events. This study aims to re-evaluate the spillway design of the Cibeet Dam using a hydraulic and structural stability analysis approach. The data used includes the Cibeet Dam planning documents, topographic data, hydrological data, geotechnical data, soil investigation data, climatological data, and reservoir capacity data. The analysis covers stability against overturning, sliding, seepage, and soil bearing capacity under three water level conditions (empty, normal, flood), and assesses construction cost efficiency. The results show that reducing the spillway crest width by 0.5 m only increases the head (Hd) by 2 cm. The spillway with an ogee crest and USBR II stilling basin is considered stable, with safety factors >1.5 under normal conditions and >1.2 during seismic events. The soil bearing capacity is also deemed sufficient to support the structure under all water level conditions.

Abstract

The Surabaya Old Town Tourism Area, particularly along Rajawali street, has experienced increased traffic activity due to the high number of tourist visits, especially on weekends. This situation has led to roadside frictions that impact road performance. This study aims to analyze the roadside frictions and traffic volume along the road segment. A quantitative approach was applied, based on the Indonesian Highway Capacity Manual (MKJI) 1997. Primary data were collected through field surveys conducted over seven consecutive days during peak hours (4:00 PM–8:00 PM) and analyzed to identify traffic characteristics at the study location. The results of the study showed that side obstacles were in the moderate to high category, with the highest traffic volume of 2,881 smp/hour on Saturday.
