Abstract

Graving Dock adalah sebuah tempat untuk membangun atau memperbaiki kapal. Struktur graving dock pada umumnya terdiri dari struktur dinding beton dan struktur pelat lantai beton. Struktur graving dock yang ditinjau saat ini sering mengalami kerusakan pada struktur pelat dan struktur dindingnya. Kerusakan yang terjadi pada pelat lantai dapat disebabkan karena umur dan material bangunan yang sudah lebih dari 50 tahun, sedangkan pada dinding graving dock dapat disebabkan karena terbuat dari pasangan bata yang ditunjang sloof yang berada di atas fondasi batu kali tetapi tidak menjadi satu kesatuan dengan fondasi tersebut. Hal itu berpotensi menyebabkan kerusakan berat dan dapat mengganggu aktivitas perbaikan kapal di graving dock. Untuk menghindari kerusakan berat, pada pengabdian masyarakat ini dilakukan perbaikan dan perkuatan pada struktur pelat lantai dan dinding graving dock. Langkah awal yang dilakukan adalah survei pendahuluan bertujuan untuk memperoleh data kondisi saat ini. Selanjutnya dilakukan analisis dan evaluasi terhadap struktur graving dock yang ada saat ini. Langkah terakhir yang dilakukan adalah desain perbaikan graving dock. Hasil desain perbaikan, didapatkan dimensi dan penulangan yaitu struktur dinding tebal 30 cm dengan tulangan D16-150, struktur dinding miring tebal 50 cm dengan tulangan D19-150, pelat lantai tengah tebal 60 cm dengan tulangan D19-150, dan pelat lantai tepi tebal 45 cm dengan tulangan D19-150.

Abstract

Accurate construction cost planning is essential to ensure project success, as inaccurate estimates may lead to delays, cost overruns, and reduced quality. Landfill construction, which is more complex than many other infrastructure projects, includes several components such as landfill work, leachate treatment facilities, and supporting infrastructure. The purpose of this study is to determine the major cost factors that have a major impact on the overall cost of building landfill sites.  With the aid of SPSS software, a regression analysis was carried out using cost data from six landfill projects in Java Island that were completed between 2013 and 2018.  With a Sig value of 0.000 (<0.05) and a very strong correlation (Pearson Correlation 0.991, within the 0.8–1.0 interval), the results show that landfill work (X3) significantly affects total costs (Y).  Leachate treatment facilities (X4) are another crucial element in a number of situations, but landfill work (X3) consistently represents the largest portion of construction costs, according to proportion analysis. These results demonstrate the growing significance of environmental facilities and point to landfill work as the main factor influencing landfill construction costs.  The study offers contractors and federal and local governments useful information for creating more precise cost estimates, maximizing budgetary allotments, and enhancing planning and development efficiency for landfill projects.
