Labor productivity is a very important factor in construction because it will affect the successful implementation of construction projects, therefore a decrease in worker productivity is highly avoided. The emergence of the Covid-19 pandemic has made changes in the implementation of construction due to the new policies that apply. The Jakarta International Stadium project experienced problems in terms of manpower during the Covid-19 pandemic, including a reduction in manpower and working hours due to restrictions on the number of workers. However, the project still has a target completion time so that there will be no longer delays. These demands affect the motivation of workers, which will then affect their productivity. This study uses a quantitative approach with the Bayesian Belief Network (BBN), to determine the magnitude of motivation during the pandemic based on the dominant variables that influence it. Based on the results of the study, the dominant variables of the five need factors based on Maslow's Theory that affect motivation are the provision of supplements to workers, health checks before work, good relations between workers, good work direction, family support, training program procurement, and decision making. The amount of motivation for the Jakarta International Stadium construction project workers during the Covid-19 pandemic was 72.90. Strategies to increase the motivation of construction project workers during the Covid-19 pandemic include providing supplements, increasing the number of health check officers, workers can interact with families virtually, training, and providing independent understanding and direction in making decisions at work.
Purpose: The current procurement of goods and services refers to the Electronic Procurement Service (E-Procurement) system in accordance with Presidential Regulation No.16 of 2018, however in its implementation the contractors still need adjustments. One of them is the contractor involved in the case study of this research which has failed in several tenders. This can create risks associated with value and profitability of the company. This study aims to cover this gap by knowing the risk factors for failure, level and the form of handling carried out by distributing questionnaires to the related contractors. Design/methodology/approach: Data analysis was performed using statistical software and the value was mapped using the Risk Relative Importance Index (RRI). Findings: The result show that the capacity of the bid files to upload is too large and there is no supplier support, are in moderate risk levels with scale respectively of 8,836 and 7,407. Problematic internet signal factors and incomplete design maturity levels are in high risk levels with a scale of 11.868 and 12.586. Meanwhile, the extreme risk level, namely the price cannot compete with other participants and the very limited time for calculating the tender, on a scale of 12,586 and 15,339 are factors that need attention.
Tingginya angka kecelakaan kerja pada industri konstruksi masih menempati posisi tertinggi di antara industri lainnya yang menyebabkan kinerja keselamatan dan kesehatan kerja menurun. Salah satu penyebabnya adalah keterlibatan banyak pihak, diantaranya adalah subkontraktor, dimana internal perusahaan ini masih memiliki manajemen yang kurang memadai. Oleh karena itu, perlu diketahui faktor-faktor dominan yang mempengaruhi pengadaan subkontraktor pada tahap perencanaan dan pelaksanaan yang mengacu pada PMBOK 2013 sebagai panduan dengan metodologi yang spesifik, agar dapat meningkatkan kinerja keselamatan dan kesehatan kerja. Metode penelitian yang digunakan adalah survey dan studi kasus. Data diolah dengan analisa statistik dan analisa faktor. Berdasarkan hasil penelitian ini peningkatan kinerja K3 didominasi oleh faktor integrasi yang baik untuk memenuhi tuntutan kerjasama dalam aspek K3.
Pada proyek konstruksi jalan tol, pekerjaan struktur bangunan atas adalah salah satu fase yang memiliki tingkat risiko tinggi. Terutama pada saat pemasangan erection girder. Penelitian ini mengambil variabel pada tahapan pekerjaan erection girder yang kemudian diperdalam dengan studi literatur dan validasi pakar. Nilai risiko yang diperoleh mengacu pada risk management PMBOK 2013 selanjutnya dipertajam dengan simulasi model risiko untuk melihat frekuensi dan sensitivitas. Hasil penelitian menunjukkan terdapat enam risiko utama dengan nilai tertinggi X14 (adanya tumpahan oli pada area kerja) sebesar 0,178 dan terendah X2 (pekerja terluka akibat terkena material atau peralatan saat proses mobilisasi) sebesar 0,129. Sensitivitas risiko tertinggi ada pada X24 (pekerja tertimpa material saat pengangkatan PCI girder) sebesar 86,9%. Upaya yang dapat dilakukan adalah memaksimalkan housekeeping area kerja, rambu, dan APD bagi pekerja sesuai dengan Permenakertrans No. 8 tahun 2010 tentang alat pelindung diri pada konstruksi bangunan sehingga dapat meningkatkan kinerja kesehatan dan keselamatan kerja.
