Abstract

A construction project is a series of activities to achieve a goal within certain time, cost and quality limits. Construction projects require resources, namely humans, materials, equipment, implementation methods, money, information and time (Kerzner 2009). Project resources are planned to achieve project goals within time, cost and quality constraints. The challenge in project implementation is how to plan an effective time schedule and efficient cost planning without reducing quality. In the road improvement project in Batuplat sub-district, the Earned Value method has not been applied as this method functions as a tool for evaluating project performance and the results of this evaluation can be used to estimate whether the project can be completed on time or not. From the results of initial observations, the author knows that in the project implementation process, weekly evaluations were not carried out, this could result in the contractor not knowing what obstacles could prevent the project from being completed on time. The author considers that the absence of this method cannot provide an estimate that this project can be completed on time because there are two possibilities that this project can be completed on time or not.

Abstract

Overcoming the problem of time delays requires handling using proven methods or alternatives such as adding work groups or adding working hours. Adding working hours and labor is usually used as a solution to speed up the completion time of a project because by adding working hours, the time that can be used to work increases so that the resulting production increases and the completion time. Adding working groups and working hours to the selected work items from the critical path, namely Class A Aggregate Foundation Layer, Wearing Layer Laston and Fc 15 mpa Concrete Structure produces a new minimum production so that the completion time of the three work items is reduced, but also increases the costs required to complete the work items. Adding Working Hours (Overtime) to the three work items on the critical path, the first hour of completion duration is reduced by 12.5% in the completion duration of the work item, the 2nd hour by 22.22% in the work item, the 3rd hour by 30% in the work item. While the cost of Class A Aggregate Foundation Layer, the 1st working hour cost is 0.15%, the 2nd hour is 0.31%, the 3rd hour is 0.31%. In the Wear Layer Laston work item, the cost is 0.08% in the 2nd hour, 0.16% in the 3rd hour and 0.16%. In the fc 15 Mpa Concrete structure work item, the 1st working hour is 2.01%, the 2nd hour is 4.01% and the 3rd hour is 4.01%. The addition of labor groups for the Class A Aggregate Foundation Layer work item, the duration is reduced by 32%, the Wear Layer Laston work item is 13%, and in the Fc 15 Mpa Concrete Structure work item is 50%. The cost of the Class A Aggregate Foundation Layer work item increased by 0.37%, the Wearing Layer Laston work item increased by 8.03% and the fc 15 Mpa Concrete Structure work item did not experience an increase.

Abstract

A project is a detailed series of activities within a limited timeframe aimed at achieving specific objectives. Resources such as manpower, equipment, materials, money, and time are crucial for project success. The research objective is to determine the impact of minimum production differences between equipment and labor on project completion time, costs, and profits. The completion time for the binder course work item, based on labor and equipment, is 0.83 days, with a minimum production used of 10,000 liters. Conversely, based on equipment's minimum production, the completion time is 0.47 days, with a minimum production used of 17,500 liters. This shows a difference in completion time of 0.35 days with a reduction of 0.43%. According to the Bill of Quantities (RAB) data, the project cost is lower compared to the project cost based on labor, equipment, and labor and equipment combined. The initial profit according to the Bill of Quantities data is Rp 337,328,068.10, and the profit based on minimum labor production is Rp 145,723,835.86, resulting in a profit decrease of -56.80%.

Abstract

Kedisiplin pekerja konstruksi dalam menggunakan Alat Pelindung Diri menjadi salah satu faktor penentu terhindarnya pekerja mengalamai kecelakaan kerja pada pekerjaan konstruksi... Penelitian ini bertujuan mengetahui hubungan kedisiplin pekerja konstruksi dalam menggunakan Alat Pelindung Diri (APD) dengan kejadian kecelakaan kerja pada pembangunan gedung perkantoran Bank NTT. Metode yang digunakan dalam penelitian ini adalah metode deskriptif korelasional dengan menggunakan pendekatan kuantitatif. Jumlah pekerja yang bekerja pada pembangunan gedung kantor Bank NTT sebanyak 75 orang dengan menggunakan teknik simple random sampling. Analisis data yang digunakan dalam penelitian ini adalah chi square dengan tingkat signifikansi α=0,05 (p-Value <0,05). Data diperoleh melalui kuesioner. Berdasarkan hasil penelitian ditemukan (17,3%) atau 13 pekerja pernah mengalami kecelakaan kerja, sedangkan (82,67%) lainnya tidak pernah mengalami kecelakaan kerja. Jenis kecelakaan kerja yang paling sering dialami pekerja adalah terjatuh 5 kasus atau (55,6%) sedangkan sisanya (33,3%) untuk meninjak paku dan (11,1%) untuk tertimpa material. Hasil uji Chi Square diperoleh p-Value 0,93 > 0,05. Artinya tidak terdapat hubungan antara disiplin penggunaan alat pelindung diri dengan kecelakaan kerja pada pekerjaan konstruksi gedung kantor Bank NTT.namun perlu adanya peningkatan Pengawasan penggunaan APD diharapkan ditingkatkan sesuai SOP yang berlaku.
