Abstract

Human resources are very important in the work environment, especially in the construction sector. Without a qualified and productive workforce, the project results will not be satisfactory. This research aims to observe the productivity of workers while constructing the pedestrian in front of the Surajaya Stadium in Lamongan, focusing on rebar work, formwork installation, and concreting using the time study method. The initial stage involves analyzing the project and collecting data that will be used as material for observing labor productivity. The productivity for foundation rebar work is recorded at 134.86 kg/person/day, and for column rebar work at 96.84 kg/person/day. The productivity value for formwork also varies, reaching 351.82 m²/person/day for slab formwork work.. Casting work has varying productivity, for example 9.10 m3/person/day for foundation casting. Several factors that affect productivity are the lack of worker skills, hot weather, and obstacles at the project site. The productivity of rebar work, formwork installation, and casting in this project is low due to the lack of worker skills, hot weather causing fatigue, and access barriers. To improve efficiency, training for workers, scheduling work hours, and managing the surrounding environment are necessary.

Abstract

In a building construction project, of course, there are many methods used to schedule a job as well as the cost budget. The purpose of this research is to determine the results of time and cost analysis on the Satnarkoba Police Lamongan Building Construction project. This research uses Critical Path Method (CPM) and Project Evaluation and Review Technique (PERT) with the help of Ms Word 2010 application program to analyze cost and time management. From the results of the analysis, a Network Diagram was found in which there was a series of critical work. Cost analysis is obtained by processing RAB and AHSP data. From this data, the volume, coefficient and wages of workers are obtained as a reference for processing workers' wage data. Based on the results of the analysis found, the critical trajectory, namely with work codes A, E, D, C, G, J, K, N, AF, and AE on a project that lasts for 180 days, gets an acceleration result of 144 days, so the chances of the project can be completed within 144 + 36 = 180 days, with a probability of 4.02%. Based on the results obtained, the average level of probability is greater than 4.02%, this is included in the very high category. In terms of costs incurred from each development, it shows optimal cost efficiency.

Abstract

The growth of the residential property market, particularly in the housing sector is currently experiencing a slowdown. This condition is influenced by economic instability and a decline in consumer purchasing power. Such circumstances pose significant challenges for developers and investors, especially those in the project development phase. Based on this background, this study aims to evaluate the financial feasibility of an investment in the Chrysant Luxury Land Housing Project, which is also expected to serve as a reference for future residential development and planning. The research method employed is Return on Investment (ROI), focusing on the construction of 11 housing units. The data analyzed include revenue details, total expenditure, and the project site plan as the basis for financial calculations and simulations. The analysis results show an ROI value of 8.8%, indicating a positive return. This suggests that the project is financially profitable and feasible to proceed as an investment endeavor.
