Abstract

ABSTRACTOne type of deep foundation is a pile foundation that is designed and has the ability to withstand axial, lateral, and uplift loads. This analysis aims to determine and compare deflections that occur on poles that are in granular soil by using the manual calculation of the p-y curve method with finite difference approaches and calculations with Allpile and Plaxis software. The analysis was conducted three times, namely on a 60 cm diameter pole at a depth of 10 meters embedded pile with lateral loads of 25 kN, 50 kN, and 75 kN. The data used to calculate the lateral deflection of the pole is secondary data. Lateral deflection analysis using Plaxis software with a load of 25 kN, 50 kN, and 75 kN obtained lateral deflection of the uppermost pole respectively 0.159 cm, 0.324 cm, and 0.545 cm. Lateral deflection analysis using Allpile software with a load of 25 kN, 50 kN, and 75 kN obtained lateral deflection of the uppermost pile by 0.08 cm, 0.16 cm and 0.29 cm. While the results of the lateral deflection analysis of the manual calculation of the p-y curve method with a finite different up to 25 kN, 50 kN, and 75 kN loads obtained lateral deflection of the uppermost pile respectively by 0.60 cm, 0.12 cm and 0.179 cm. So the approximating calculations are manual calculation of the p-y curve method with calculations with Allpile software. Nash-Sutcliffe Efficiency (NSE) value calculation of the p-y curve method with plaxis software at lateral load 25 kN, 50 kN, 75 kN obtained consecutive NSE values of -5,946, -6,439, dan -30,118 all of which have unsatisfactory performance rating. Different with curve p-y method  compared with Allpile that has consecutive NSE values of 0,876, 0,876, 0,876, dan 0,605 all of which have very good performance rating. ABSTRAKSalah satu jenis fondasi dalam adalah fondasi tiang yang didesain dan memiliki kemampuan untuk menahan beban aksial, lateral, dan uplift. Analisis ini bertujuan untuk mengetahui dan membandingkan defleksi yang terjadi pada tiang yang berada pada tanah granuler dengan menggunakan perhitungan manual metode kurva p-y dengan pendekatan beda hingga dan perhitungan dengan software Allpile dan Plaxis. Analisis dilakukan tiga kali percobaan yaitu pada tiang berdiameter 60 cm pada kedalaman tiang tertanam 10 meter dengan beban lateral sebesar 25 kN, 50 kN, dan 75 kN. Data yang dipakai untuk menghitung defleksi lateral tiang adalah data sekunder. Analisis defleksi lateral menggunakan software Plaxis dengan beban 25 kN, 50 kN, dan 75 kN didapatkan defleksi lateral tiang paling atas berturut-turut sebesar 0,159 cm, 0,324 cm, dan 0,545 cm. Analisis defleksi lateral menggunakan software Allpile dengan beban 25 kN, 50 kN, dan 75 kN didapatkan defleksi lateral tiang paling atas berturut-turut sebesar 0,08 cm, 0,16 cm, dan 0,29 cm. Sedangkan hasil analisis defleksi lateral perhitungan manual metode kurva p-y dengan pendekatan beda hingga dengan beban 25 kN, 50 kN, dan 75 kN didapatkan defleksi lateral tiang paling atas berturut turut sebesar 0,60 cm, 0,12 cm, dan 0,179 cm. Jadi perhitungan yang saling mendekati adalah perhitungan manual metode kurva p-y dengan perhitungan dengan software Allpile. Perhitungan nilai Nash-Sutcliffe Efficiency (NSE) metode kurva p-y dengan software Plaxis pada beban lateral 25 kN, 50 kN, dan 75 kN didapatkan nilai NSE berturut-turut sebesar -5,946, -6,493, dan -30,118 yang ketiganya memiliki rating performa tidak memuaskan. Berbeda dengan metode kurva p-y dibanding dengan Allpile memiliki nilai NSE berturut-turut sebesar 0,876, 0,876, dan 0,605 ketiganya mempunyai rating performa yang sangat baik.

Abstract

One of the obstacles when working on a construction site is industrial accidents. This is evidenced by the number of accidents at work in 2020. The number increased from 85,109 at the beginning of 2020 to 108,573. This study aims to define implementing the K3L risk management system and measures to minimize emerging risks. This study used descriptive qualitative methods. The data analysis process is conducted through Hazard Identification, Risk Assessment, and Risk Control (HIRARC), which includes three steps: risk identification, risk analysis or assessment, and risk mitigation. Data was collected by distributing checklist questionnaires to 30 employees and interviewing HSE project managers. Data were obtained from various sources relevant to the study. A study of the project identified 29 risk variables. According to the processed data, when constructing a roof with a risk index of 5.90, it is known that the most significant risk appears in the variable risk of falling from a high place. On the other hand, the slightest breakage risk of the Sling TC hazard variable is 2.56 when read from cast steel structures with the resulting hazard index. It is essential to monitor risk as a form of continuous improvement to minimize risk when suppressing or reducing its likelihood and severity

Abstract

Design flood discharge has become an important parameter in hydraulic construction design planning. When analyzing it, return period selection is crucial because it will determine the amount of design flood discharge. The return period selection is adjusted to the characteristics of the Watershed  (DAS). The Sand Pocket planning location is in Woro River, Klaten, Central Java. The unavailability of design flood discharge data at the observation site resulted in the design flood discharge analysis being carried out. This study focuses on comparing the magnitude of design flood discharges from different return periods, namely Q5th, Q10th, Q25th, Q50th, and Q100th. After the flood discharge is obtained, it is utilized to calculate the dimensions of the Sand Pocket construction. Each return period used in this study produced different dimensions of the building in several parts. This analysis shows the different dimensions of the building due to differences in flood discharge generated, namely the Main Dam and Sub Dam parts including effective height, upstream slope (m), flow height above the lighthouse, freeboard, foundation depth, and base. In the part of apron, there are differences of floor length and thickness dimension. The difference dimensions also appeared on the upstream side slope of Main Dam and Sub Dam. This return period selection determines the amount of the design flood discharge that will affect the dimensions of the Sand Pocket that will be planned.

Abstract

Looking at the total level of rapid development of construction work, which is relatively fast, it becomes a challenge for the construction world. This is followed by the development of a very diverse method of various construction implementations applied in the process. In every construction project implementation, the main factor that makes the project successful or not is in terms of both time and cost. This research uses quantitative descriptive analysis research. In this descriptive analysis, which was carried out at the Mapolres Mapolres Advanced Building Project, the aim was to determine the time performance and find solutions to problems that existed in the implementation of this project. On the schedule variance graph (SV), the implementation of this project is all positive. Shows that this positive value is that the implementation of the work has accelerated or has not experienced delays, and the performance of the project implementation is better and faster following the initial planning. The value of the schedule performance index (SPI) on the overall implementation of this project from the 8th week to the 11th week shows a value of more than one (>1), so the project is completed faster than what has been planned.

Abstract

Proses pembangunan sebuah proyek konstruksi kerap terjadi sesuatu yang tidak diinginkan seperti terjadinya keterlambatan pekerjaan pada proyek. Keterlambatan pekerjaan proyek dapat terjadi karena faktor yang beda-beda seperti kondisi cuaca yang tidak mendukung, perubahan desain dan kesalahan dalm perencanan. Maka dari itu diperlukan alternatif yang bisa digunakan untuk menunjang percepatan penyelesaian proyek, alternatif tersebut dapat berupa penambahan jam lembur, pengunaan alat yang produktif, penambahan jumlah pekerja, penggunaan matrial yang cepat pemasangannya dan metode konstruksi yang lebih cepat. Pelaksanaan yang mengalami keterlambatan perlu dilakukan percepatan. Salah satu metode percepatan dengan alternatif penambahan jam kerja (lembur) yang dilakukan yaitu crashing program dengan pengurangan durasi proyek agar dapat mengejar prestasi yang tertinggal pada waktu-waktu sebelumnya dengan melakukan analisis jaringan kerja berupa CPM. Data yang dibutuhkan dalam penelitiam ini adalah data sekunder berupa data time schedule, rencana anggaran biaya proyek. Hasil analisis pada proyek pembangunan Gedung Perkuliahan Fakultas Syariah Universitas Islam Negeri Walisongo, Kota Semarang Jawa Tengah, diketahui total anggaran biaya proyek dalam kondisi sesudah crashing dengan alternatif penambahan jam kerja maksimal selama empat jam didapat sebesar Rp 20.221,318,481.22 atau lebih mahal 0.9% dari total anggaran biaya peoyek pada kondisi normal dan durasi pelaksanaan proyek didapat 209 hari kerja atau lebih cepat 20,83% dari durasi normal sebelum crashing. Dari prnrlitian ini di simpulkan bahwa dengan meneraokan sistem penambahan jam kerja merupakan alternatif program crashing yang efektif dan ekonomis, karena dengan menerapkan sistem penambahan jam kerja durasi lebih cepat dan anggaran total biaya proyek tidak terlalu besar dari biaya anggaran normal.

Abstract

Abstract. Buildings with component degradation are a common challenge for all construction companies across the world. There are various building's components that it is challenging for construction companies to manage them all at once. It was not considered that the building agency is responsible for more than one building at a time. These issues have gotten more complicated as a result of the building agencies' limited financial resources for building maintenance. This study attempts to provide a visible solution to manage the building maintenance strategy based on complex building maintenance problems. The Analytical Hierarchy Process was used to give a complete way for assessing the building's condition (AHP). This method developed in this study was applied to define the building condition and followed by determining the building priority to be maintained. The building component in this study was specified into three specific components such as interior, exterior, and building utility. To complete this method, a three-level priority factor was determined with consideration from the safety factor follow by the functionality factor, dan the last is an esthetic factor. The developed model shows a proper and reliable solution related to the degradation of building components and their functionalities.

Abstract

Semarang City, the capital city of Central Java Province, is one of the cities with a dense population in Indonesia of 1.7 million people and ranks 4th in the region with a population of Central Java. With increasing population growth and limited land for infrastructure development, adding a building floor can solve infrastructure with limited land by utilizing every building space. This study uses the Meyerhof method in 1956 regarding the bearing capacity of deep foundations using NSP-T data and ETABS v18.1 application as an analysis of the superstructure. The results of this study found that the carrying capacity of single and group foundations with Meyerhof calculations with a foundation bearing capacity of 906.189 tons was able to support the maximum load of the superstructure of 647.637 tons after obtaining the addition of one floor and changing the steel roof structure to a concrete slab roof by using the roof as open areas and connections between buildings.

Abstract

The high level of infrastructure development at present forces old buildings to undergo repairs or even demolition to make way for new buildings that are more suitable and representative. The resulting demolition waste is usually discarded, becoming solid waste. The solution to the above problem is recycling the concrete waste as an alternative aggregate to replace some or all of the natural aggregates in the concrete mixture. Concrete with recycled aggregates is made with several composition variations of replacement to natural coarse aggregates, which is 0%, 25%, 35%, 45%, and 50%. The concrete will be tested for compressive strength at 28 days from the concrete mixture preparation. The research results showed that the highest compressive strength was found in the variation with a 25% replacement of natural coarse aggregates, which was 50.1 MPa, and the optimum compressive strength value is obtained at the variation of 23.51% recycled coarse aggregate substitution.
