Abstract

Roads are the main function as infrastructure for all forms of land transportation. For those who use the road, because a good road has a beneficial influence on the community, the road serves as the main foundation for economic turnover activities and social activities of the community. So comfort and tranquility when driving are very important factors before the construction of road pavement construction, the stability of a road must first be known the carrying capacity of the soil as a foothold.  The carrying capacity of the soil that damages the pule-sarirejo road was evaluated by researchers. Factors affecting the decrease in soil carrying capacity were also studied in this study. Testing water content with an average value of 15.39% which includes high water content, data processing shows that the road bottom soil on Jalan Pule – Sarirejo has a low carrying capacity value in this test. For testing the boundaries Atterberg belongs to the group of clay soil types. with a PI value of 58.85% has a high platicity value. However, it is known from the results of CBR testing that the CBR value of the road base soil is 7.00%, included in the "sufficient" category and for the shear strength value is 0.21 kg/cm² and is still classified as sandy clay.

Abstract

In construction projects, particularly in the development of the Co-Working Space in Lamongan Regency, discrepancies between the planned schedule and actual outcomes often occur, both in terms of time and cost. This is generally caused by ineffective planning and control during project execution. This study aims to analyze cost and time management of the project to achieve more efficient and timely implementation. The research method applies the Critical Path Method (CPM) as the primary approach to determine the critical path and minimum project duration, complemented by the Program Evaluation and Review Technique (PERT) to estimate time uncertainties. The results show that using CPM, the critical path involves activities A, B, D, F, G, E, V, X, AA, AB, AD, AE, AG, AK, AT, BA, AU, AV, AY, BB, BD, AZ, BH, and BE with a total duration of 136 days, saving 22 days from the initial plan of 158 days. Using PERT with the same critical path, the project is estimated to be completed in 148 days, saving 10 days, with a cumulative distribution value of 3.7, indicating a 99.98% probability of project completion before the target date. In conclusion, CPM and PERT are effective for controlling project cost and time, with CPM providing greater time efficiency.

Abstract

The Warehouse and Musholla Development Project for the Mainsub Tuban II-IV Area is scheduled to be completed within 18 weeks with a contract value of Rp1,543,013,748.08. The purpose of this study was to determine the cost and time performance and the factors that caused the delay and progress of the project. The method used in this study is the Earned Value method which uses elements of cost and time as well as physical performance of the work. Data obtained from the project include the project Time Schedule, Budget Estimate Plan (RAB), weekly project reports, and actual costs, then cost, schedule, variance, performance index analysis was carried out by explaining the problems that emerged during the study. From the results of the analysis, it is known that the costs incurredare lower than the budgeted costs (costs are more efficient than planned) and the completion of the project is according to schedule, which is 18 weeks. However, there was a delay in progress in the 5th and 6th weeks indicated by the SPI (Schedule Performance Index) values of 0.766 and 0.934, which means that the implementation time is slower than the planned schedule caused by technical problems with the implementation of soil excavation that is not in accordance with the plan. The delay in progress can be pursued by accelerating in the 10th week to the 15th week with quite significant progress. The estimated final cost calculation result of the project is Rp1,492,777,469.16 with a completion time of 18 weeks.

Abstract

Time and cost management play an important role in the success of a construction project. Therefore, project planning and scheduling must be done carefully before implementation begins. The Soko – Karangbinangun road improvement project faces a number of challenges, especially in terms of time management. In this project, the work that was supposed to start on September 3 according to the contract, was delayed and only started on September 23. This condition has the potential to cause delays in project completion. This study aims to compare the results of theoretical calculations with the factual conditions in the field, and to evaluate the possibility of accelerating the project schedule without sacrificing cost efficiency. The acceleration method used in this study is the overtime system with variations in duration of 1, 2, and 3 hours. Ms. Project is used as a tool to identify the critical path in the project. The results of the analysis show that out of 9 initial work items, there are 8 items included in the critical path. With a variation of 1 hour overtime, the project duration can be accelerated to 68 days, 10 days shorter than the normal duration of 78 days, with a crashing cost of Rp. 1,233,684,874.50 from the normal cost of Rp. 1,229,803,328.00. For 2-hour overtime, the work can be completed in 59 days, 19 days faster than the normal duration, with a crashing cost of Rp. 1,246,809,926.00. While for 3-hour overtime, the project can be completed in 51 days, or 27 days faster than the normal duration, with a crashing cost of Rp. 1,264,842,460.50. From the results of the analysis that have been known, it can be concluded that the 2-hour overtime variation method is more effective to apply.

Abstract

Abstrak Tiang pancang merupakan salah satu jenis pondasi dalam yang berfungsi untuk menyalurkan beban struktur kelapisan tanah keras. Proyek pembangunan jalan tol Romokalisari ini berlokasi di jalan tol perbatasan kota Surabaya dan Gresik yang merupakan salah satu bentuk dari upaya percepatan dalam pembangunan infrastruktur yang berada di wilayah Provinsi Jawa Timur. Tujuan dari penelitian ini untuk menghitung daya dukung tiang pancang yang diperoleh dari hasil kalendering pada proyek Romokalisari zona 2 STA 0+900 dengan menggunakan formula Hiley, WIKA, Engineering New Record ENR, Navy - McKay ataupun formula Danish. Berdasarkan hasil kalendering didapatkan nilai kapasitas daya dukung tiang pancang rata-rata terbesar yaitu dengan mengunakan formula WIKA yaitu sebesar 159,08 ton. Formula WIKA memberikan nilai daya dukung tiang pancang terbesar dibanding metode lainnya. Untuk nilai kapasitas daa dukung tiang pancang terendah yaitu menggunakan formula Navy MC-Kay yaitu sebesar 90,90 ton. Dari hasil perhitungan daya dukung tiap formula didapatkan nilai Qu rata - rata tiap formula yang masih memenuhi daya dukung ijin dengan hasil Qu Hiley 135,22 ton, Qu WIKA 159,08 ton, Qu ENR 109,01 ton, Qu Navy-MCKay 90,90 ton, dan Qu Danish 128,17 ton. Sehingga daya dukung tiang pancang pada proyek Romokalisari zona 2 STA 0+900 dapat dikatakan aman. Kata kunci: Pondasi, tiang pancang, daya dukung tiang pancang, kalendering  Abstract Pile is one type of deep foundation that serves to channel the load of the structure to the hard soil layer. The location of Romokalisari toll road project is on Surabaya - Gresik which is as one of infrastructure development in the East Java Province. The purpose of this study is to calculate the carrying capacity of piles obtained from the results of calendaring in the Romokalisari zone 2 Project STA 0+900 using the Hiley, WIKA, Engineering New Record ENR, Navy - McKay, and the Danish formulas. Based on the results of the calendaring, the WIKAs formula is commonly used for the calculation of the carrying capacity of piles, which is 159,08 tons. The WIKA formula is largest of the carriying capacity. From the result of calculating the carrying capacity of each formula, the average Qu value of each formula that still meets the license carrying capacity with the results of Qu Hiley 135.22 tons, Qu WIKA 159.08 tons, Qu ENR 109.01 tons, Qu Navy-MCKay 90 .90 tons, and Qu Danish 128.17 tons. So that the carrying capacity of the piles in the Romokalisari zone 2 Project STA 0+900 can be said to be safe. Keywords: Fondation, piles, pile carrying capacity, calendaring
