Abstract

Setiap proyek konstruksi umumnya mempunyai rencana waktu penyelesaian dalam penjadwalannya yang ditetapkan berdasar dari sumber daya yang dimiliki. Masalah timbul ketika waktu realisasi aktual melebihi waktu perencanaan yang menyebabkan keterlambatan. Dampaknya adalah pemborosan sumber daya, baik waktu, biaya dan tenaga. Selain itu keterlambatan penyelesaian suatu proyek juga menimbulkan perselisihan antar stakeholder. Berdasarkan hasil survei pendahuluan terjadi keterlambatan waktu penyelesaian selama dua bulan pada proyek PT. Jatim Taman Steel yang berlokasi di Gresik yang disebabkan oleh beberapa faktor di tahap pra konstruksi dan tahap konstruksi. Beberapa penelitian sebelumnya telah melakukan analisa faktor penyebab keterlambatan diberbagai proyek konstruksi tetapi kebanyakan hanya menggunakan satu sudut pandang saja, dimana dalam upaya meminimalisir keterlambatan tersebut belum banyak menggunakan kombinasi dengan Framework Lean Six Sigma. Penelitian ini bertujuan untuk memperoleh faktor–faktor dominan penyebab timbulnya keterlambatan pada proyek PT. Jatim Taman Steel dari tiga sudut pandang yaitu owner, kontraktor dan konsultan. Selain itu dilakukan perumusan solusi dalam mengatasi keterlambatan tersebut dengan menggunakan pendekatan Lean Six Sigma Framework. Lean Six Sigma Framework memiliki konsep fase dalam mengeliminasi pemborosan secara lebih efisien dan sistematis. Variabel penelitian dirumuskan berdasarkan hasil studi literatur dengan pengukuran menggunakan skala relevansi melalui bantuan kuisioner. Untuk pengambilan sampel dilakukan dengan teknik purposive sampling. Responden penelitian adalah manajer proyek, staff ahli, direktur dan konsultan mesin. Pendeskripsian variabel hingga perumusan solusi dilakukan secara bertahap menggunakan fase DMAIC (Define, Measure, Analyze, Improve dan Control) dimana digunakan konsep Lean Construction di tahap Improve. Untuk meminimalisir keterlambatan pada proyek pembangunan pabrik baja PT. Jatim Taman Steel yaitu dengan menerapkan beberapa teknik berikut, yaitu Alliance & Partnering, Work Structuring dan Daily Huddle Meeting, mampu mengurangi pemborosan waktu dari 60 hari menjadi hanya sekitar 46 hari atau mampu meminimalisir keterlambatan sebesar 23,333%. ================================================================================================= Every construction project generally has a plan of completion time in scheduling stipulated or based on its own resources. Problems arise when the actual realization time exceeds the planning time which causes delay. The impact is a waste of resources in time, cost and energy. Furthermore, the delay of a project completion also creates disputes among stakeholders. Based on the results of the preliminary survey, there was a two-month delay of completion at PT. Jatim Taman Steel project located in Gresik which was caused by several factors in pre-construction and construction stages. Many studies have analyzed the factors causing delays in various construction projects but most of them only use one point of view and there are also some studies which examine how to minimize them. This study is aimed to obtain the dominant factors causing delay at PT. Jatim Taman Steel projects from three points of view namely the owner, contractor and consultant. The researcher also used the formulation of solution to overcome the delay by using the approach of Lean Six Sigma concept. Lean Six Sigma has the concept of phase in eliminating waste referring to the waste of time which can be done more efficiently and systematically. The research variables were formulated based on the results of a literature study with measurements using a scale of relevance through questionnaires. Purposive sampling technique was used to conduct sampling. The research respondents are made up of the project managers, expert staffs, directors and engine consultants. The description of variables to the formulation of solution was conducted gradually by using DMAIC phase (Define, Measure, Analyze, Improve and Control) as well as the concept of Lean Construction. As a solution to minimize delays in the construction project of the steel factory at PT. Jatim Taman Steel, the following techniques are used: Alliance & Partnering, Work Structuring and Daily Huddle Meeting. With these techniques used simultaneously, they can reduce waste of time from 60 days to only about 46 days or able to minimize the delay up to 23.333%
