Abstract

Abstrak   Pada Proyek Pembangunan Gedung Kantor Pelayanan Pajak Pratama – Natar, ditemukan masalah seperti gambar yang tidak dapat dilaksanakan, perubahan rencana kerja, dan perubahan scope pekerjaan. Tujuan penelitian adalah menganalisa faktor utama yang mempengaruhi perubahan desain dalam durasi pelaksanaan. Metode yang digunakan dengan melakukan penyebaran kuesioner sebagai data utama dan wawancara sebagai data pendukung, yang kemudian dianalisis menggunakan Analytical Hierarchy Process (AHP). Hasil penelitian dari perubahan desain pada proyek konstruksi, yang disebabkan oleh ketidaksesuaian antara rencana dan kondisi lapangan, mungkin berdampak signifikan terhadap durasi proyek. Perubahan ini dipicu oleh penyesuaian kondisi lapangan dan permintaan dari pihak pemilik proyek, seperti penambahan pos jaga serta instalasi air conditioner di area yang tidak direncanakan sebelumnya. Kesenjangan ini menyebabkan keterlambatan proyek, yang seharusnya telah mencapai 97% pada minggu ke-39, namun realisasinya hanya 63%. Faktor-faktor seperti penyesuaian lapangan dan permintaan pemilik proyek, termasuk penambahan fasilitas tak terduga, berkontribusi dominan terhadap keterlambatan dan peningkatan biaya kemudian dari 13 faktor yang dianalisis, faktor dominan yang mempengaruhi perubahan desain yaitu kesalahan estimasi biaya (prioritas 0,098%), ketidaktersediaan standar material (prioritas 0,085%), dan penundaan pekerjaan (prioritas 0,084%). Kesimpulan adalah bahwa perubahan desain dalam proyek konstruksi paling dominan dipengaruhi oleh faktor Kesalahan Estimasi Biaya dan Ketidaksesuaian Desain dengan Kondisi Lapangan, berdasarkan bobot prioritas tertinggi hasil metode Analytical Hierarchy Process (AHP). Kedua faktor ini berasal dari aspek perencanaan, yang terbukti lebih berpengaruh terhadap durasi proyek dibandingkan faktor pelaksanaan.   Kata kunci: manajemen perubahan, durasi pelaksanaan, AHP, faktor perencanaan, faktor konstruksi.   Abstract   The construction of the Pratama Tax Office Building in Natar encountered several issues, including unimplementable drawings, changes in work plans, and alterations in the project scope. This study aims to analyze the dominant factors influencing design changes that affect project duration. The research employed a questionnaire as the primary data collection method and interviews as supporting data, analyzed using the Analytical Hierarchy Process (AHP). The results indicate that design changes, triggered by discrepancies between the planning documents and actual site conditions, significantly impacted the project's timeline. These changes were largely driven by field adjustments and client requests, such as additional guard posts and unexpected air conditioning installations. The gap between plan and execution caused a delay, where the project was expected to reach 97% completion by week 39 but only achieved 63%. From the 13 factors analyzed, the most influential on design changes were cost estimation errors (priority 0.098%), unavailability of standard materials (0.085%), and work delays (0.084%). The study concludes that design changes in construction projects are predominantly influenced by planning-related factors, particularly cost estimation errors and inconsistencies between design and site conditions. These planning factors have a greater impact on project duration than those arising during execution.   Keywords: change management, project duration, AHP, planning factors, Construction factors.

Abstract

Natural disasters often occur in hilly areas in Lampung Province, namely landslides. Landslides that occur due to increased pore water pressure. The 2012 GeoStudio SLOPE / W program can analyze slope stability that can be modeled according to the original conditions in the field and can know the value of the safe slope factor. In this study, there were three cross section slopes with three groundwater conditions, namely the condition of the groundwater level at the base of the slope, half the height of the slope and following the maximum height of the cross section of the slope. Land property data needed include : cohesion, shear angle in soil and weight of soil contents. Slope stability is achieved when the retention force is greater than the driving force. The results of the analysis of slope stability show that the condition of the groundwater is very influential on slope stability, can be seen from the results of GeoStudio SLOPE / W 2012 analysis in simulation 1 and simulation 2 safe factor values obtained >1.25 that is  slopes are in safe status, while in simulation 3 the saturated condition has a safe factor <1,25 that is unsafe slopes or landslides, it is recommended to take care to prevent landslides. Key words : soil, slope stability, safety factor, geostudio slope/w 2012

Abstract

There are several factors that effect the level security of a slope. Such as the condition of a slope with large loads, steep slope and heavy rain condition. The landslide and slope would often occurs on some double track lines on Martapura – Baturaja train because of this things. Therefor, the reinforcement is needed so that the slope is more stable around the slope. The results of physical and mechanical properties of the soil are based on the results of laboratory tests and research in the field. so the PLAXIS program was used in analyzing the stability of the existing slope based on the data. From the results of the program calculation shows that the condition of the slope is not stable. because the safety value indicates 0,89 for saturated conditions and 0,67 for dry conditions and 0,91 for partially saturated conditions. Furthermore, slope stability analysis who was reinforced by a combination of soil retaining wall and borepile. there has been an increase in safety value of 1,30 for saturated conditions, 1,66 for dry conditions and 1,65 for partially saturated conditions. This shows that the slope is stable and the reinforcement design is safe and able to withstand landslides. Keywords : Analysis of Slope On Sandy Clay

Abstract

AbstractThe development of infrastructure in Indonesia is increasing in various regions such as the construction of reservoirs, dams and other construction. One of the important things that became the basis of development is foundation ground. Therefore, it is necessary to know the type of soil used and the permeable nature of the soil. Soil permeability illustrates the ability of soil to pass water. In this study to determine the permeability of the soil by using a cubic mold and compare the results of soil permeability obtained from compacted soil using the pressure method and the standard method. Soil samples used were from Pamenang village, Pringsewu. Soil taken is disturbed and undisturbed soil samples. The soil was then compacted by a standard method and with a pressure test method at a pressure of 5 MPa, 10 MPa and 15 MPa. Then the permeability test is carried out to get the permeability coefficient. The results of observations in the laboratory show the greater pressure applied to the soil, the smaller coefficient of permeability. The relationship between the permeability coefficient with standard compaction method and the pressure method get the permeability coefficient value so that the pressure is between 5 to 10 MPa. Keywords: Soil, Compaction, Pressure and Permeability. AbstrakPerkembangan pembangunan infrastruktur di Indonesia sedang meningkat diberbagai daerah seperti pembangunan waduk, embung, bendungan dan konstruksi lainnya.

Abstract

The train is a means of transportation favored by the community because the train is one of the modes of transportation that has special characteristics and advantages. Along with the development of infrastructure development in Lampung Province and South Sumatra Province, the planning and design of a building must be done carefully and well, one of them is by building a double track between Giham - Martapura, South Sumatra because the application of one track has many obstacles. It is hoped that the addition of the double track can make the train schedule more timely and can improve the quality of the trip. Based on the results of the Atterberg boundary test the soil originating from the undisturbed soil sample of the Giham-Martapura railroad gets an PI value <LL-30 (26.51% <27.95%), then the land based on the AASHTO system is classified into A -7-5 that is clay soil and as subgrade material has normal to poor evaluation. Keywords: railroad, land, double track, slope protection.

Abstract

The level of slope safety is influenced by several factors. Such as slope conditions with largeloads, steep slopes and heavy rain conditions. This often results in landslides around the TransSumatra toll road, Pematang Panggang. So that around the slopes reinforcement is needed so thatthe slopes are more stable.Based on the results of laboratory tests and research in the field, the results of the calculation ofthe slope safety value program with a 30% saturation degree condition, the safe factor value is1.2946, the degree of saturation 40%, the safe factor value is 1.2881 and the degree of saturationis 60%, the safety factor value is equal to 1,2761. Because the lowest safe factor value is at 60%saturation degree, slope stability is handled at 60% saturation degree, which is strengthened bythe cutting method on the slope body and using sheet pile to get slope reinforcement. Two methodsof handling slope stability were carried out. From the comparison of slope stability handling with60% degree of saturation, the safe slope conditions are in handling one because there is nosubsidence and soil displacement to the free slope area.

Abstract

The development of infrastructure development in Indonesia is increasing in various areas, such as the construction of reservoirs, reservoirs, dams and other constuctions. One of the important things that is the basis of development is land because almost all buildings stand on the ground. Therefore, it is necessary to know the type of soil used and the nature of the soil permeability. Soil permeability describes the ability of the soil to pass water. Soil samples used were soil samples from Pamenang village, Pagelaran sub-district, Pringsewu district. Soil samples taken are disturbed and undisturbed soil samples. The soil is then compacted by the standard method and with the pressure method test apparatus at a pressure of 2,5 MPa, 5 MPa, 7,5 MPa, 10 MPa, 15 MPa, 20 MPa, and 30 MPa, each method has one sample being tested. Furthermore the permeability test was carried out to obtain the permeability coefficient value.Results from observations in the laboratory show that the greater the pressure exerted on the soil, the smaller the permeability coefficient. The relationship between the permeability coefficient and the standard compaction method and the pressure method obtained different permeability coefficient values.Keyword : Soil, Compaction, Pressure and Permeability
