Abstract

The performance of human resources in the project environment is an important factor affecting the smooth running of the work. Lack of worker performance will affect the process of completing a project. Variables that affect worker performance are ability, motivation, and discipline along with their indicators. The purpose of this study was to determine the effect of the ability, motivation, and work discipline on the performance of building construction workers in Jabodetabek. The research method was carried out by distributing questionnaires to 40 building construction workers in Jabodetabek. Then the data were analyzed using Statistical Variance-Based Structural Equation Modeling (VB-SEM) using the Smart Partial Least Square (SmartPLS). After doing the analysis, it was found that the ability variable has a very significant and strong effect on the performance of workers, meaning that the presence of good worker abilities can cause worker performance to increase. The motivation variable has an effect but not a sign on the performance of workers and the discipline variable has a significant but not strong effect on the performance of workers, meaning that discipline can improve worker performance so that it can help increase company productivity to be optimal.   Abstrak Kinerja sumber daya manusia di lingkungan proyek menjadi faktor penting yang mempengaruhi lancarnya pekerjaan. Kurangnya kinerja pekerja akan berdampak pada proses penyelesaian suatu proyek. Variabel yang berpengaruh terhadap kinerja pekerja adalah kemampuan, motivasi, serta disiplin beserta indikatornya. Tujuan penelitian untuk mengetahui pengaruh variabel kemampuan, variabel motivasi, serta variabel disiplin kerja terhadap kinerja pekerja konstruksi gedung di Jabodetabek. Metode penelitian dilakukan dengan membagikan kuesioner kepada 40 orang pekerja konstruksi gedung yang berada di Jabodetabek. Kemudian data di analisis dengan menggunakan statistik Variance-based Structural Equation Modeling (VB-SEM) dengan menggunakan bantuan program Smart Partial Least Square (SmartPLS) 3.0. Setelah dilakukan analisis diperoleh bahwa variabel kemampuan berpengaruh sangat signifikan dan kuat terhadap kinerja pekerja artinya dengan adanya kemampuan pekerja yang baik maka dapat menyebabkan kinerja pekerja meningkat. Variabel motivasi berpengaruh tetapi tidak signifikan terhadap kinerja pekerja serta variabel disiplin berpengaruh signifikan namun tidak kuat terhadap kinerja pekerja artinya disiplin dapat meningkatkan kinerja pekerja sehingga dapat membantu meningkatkan produktivitas perusahaan menjadi optimal.

Abstract

Constructability enhancements is an effort to improve construction projects’ performance by implementing knowledges and experiences of expert project participants. The purpose of this study was to determine the correlation between the contractor's performance and the implementation of constructability enhancements prnciple, especially in the main phase of the project which is the construction phase of the building in Jabodetabek. The method used in this study is descriptive quantitative, where collected research data in the form of questionnaires’ responses has to be validated by experts through Focus Group Discussions (FGD). The research data were analyzed by linear regression test and Relative Importance Index (RII). The results obtained from this study are that there is a relatively strong positive correlation between the contractor's performance and the implementation of constructability enhancements principle in construction projects in Jabodetabek. The linear regression equations obtained from the results of data processing are Y = -20,338 + 4,938 X, and in its implementation in the field which tested by the RII method, shows that the efforts to enhance constructability related to material scheduling and project documentation are the efforts that have the best implementation in construction projects in Jabodetabek.   Abstrak Peningkatan constructability merupakan suatu upaya dalam proyek untuk meningkatkan kinerja dalam pelaksanaan proyek konstruksi dengan pengimplementasian pengetahuan serta pengalaman para partisipan ahli proyek. Tujuan dilakukan penelitian ini adalah mengetahui korelasi antara performa peran kontraktor di lapangan dengan terlaksananya peningkatan constructability khususnya dalam bidang pelaksanaan pada proyek konstruksi gedung bertingkat di Jabodetabek. Metode yang digunakan merupakan deskriptif kuantitatif, dimana pengumpulan data penelitian berupa kuesioner harus divalidasi oleh pakar melalui Focus group Discussion (FGD). Data penelitian dianalisis dengan uji regresi linear dan Relative Importance Index (RII). Hasil yang diperoleh dari penelitian ini adalah terdapat korelasi positif yang tergolong kuat antara performa peran kontraktor dengan terlaksananya peningkatan constructability dalam proyek di Jabodetabek. Adapun persamaan regresi linear yang didapatkan dari hasil pengolahan data adalah Y = -20,338 + 4,938 X, serta dalam pelaksanaan nya di lapangan yang diuji dengan metode RII menunjukan bahwa upaya peningkatan constructability yang berkaitan dengan penjadwalan material serta pendokumentasian pelaksanaan dalam proyek merupakan upaya-upaya yang memiliki pelaksanaan paling baik dalam proyek konstruksi di Jabodetabek.

Abstract

This research purpose is to offer insights to property owners and developers whose focus tends to be solely on the initial costs of green buildings, and aligning with the requirements set forth by Minister of Public Works and Public Housing Regulation No. 21 of 2022, effective from 2022, which mandates green buildings to obtain Building Structure Approval (PBG) and Functional Worthiness Certificate (SLF). Drawing from the 2013-2018 Green Building Council Indonesia (GBCI) report, which indicates a mere 2% certification rate for buildings exceeding 12 floors, this study seizes the opportunity to delve into how green building considerations influence financial decisions. Surveying 102 experienced respondents in green building practices, this research employs green building factor analysis, value engineering, life cycle cost analysis, and Structural Equation Modeling (SEM)-PLS to scrutinize the factors influencing cost performance in green buildings. The findings spotlight 10 critical green building factors pivotal for securing certification, alongside unveiling correlations between initial costs, operational costs, and life cycle costs. Anticipated outcomes encompass facilitating compliance with Minister of Public Works and Public Housing Regulation No. 21 of 2021, and nurturing the development of green buildings in Indonesia. Implications span regulatory compliance, informed financial strategies, green building advancement, and knowledge dissemination. This study aims to simplify comprehension of the financial ramifications of green buildings, furnishing practical guidance for developers in navigating the intricacies of cost-sustainability equilibrium.
