Abstract

The influences of shells utilization as smooth aggregate replacement by using sands beach on the concrete compressive strength and the quality of k-200, the use of smooth aggregate substitutes, such as manually broken clam shells and beach sand obtained from Paciran, Lamongan Regency. The mixture used in making concrete is concrete with quality K-200 (fc'16.60 Mpa). Concrete sand will be replaced by 50% with beach sand, and mixed variations will be carried out with the addition of shells by 10%, 15%, and 20%. The test results show that the average compressive strength of normal concrete is 16.60 Mpa. For a mixture with shell waste by 10% and sea sand by 50%, the average compressive strength value is 15.09 Mpa. In a mixture with shell waste by 15% and sea sand by 50%, the average compressive strength value is 14.62 Mpa. While in a mixture with shellfish waste of 20% and sea sand of 50%, the average compressive strength value is 14.13 Mpa. The concrete variant with the highest average compressive strength value is the normal variant with a value of 16.60 Mpa, while the concrete variant with the lowest average compressive strength value is the variant with shell waste of 20% and sea sand of 50%, with a value of 14.13 Mpa.

Abstract

Investment is the activity of allocating funds to assets or projects that aim to generate profits in the future. The housing sector is one of the attractive investment alternatives because its demand continues to increase. This study aims to assess the feasibility of investing in Sakura type houses at Chrysant Luxland Lamongan Housing project. The method used is investment feasibility analysis with the Net Present Value (NPV) approach. The data analyzed includes development costs, sales assumptions, and relevant interest rates. A descriptive quantitative approach was used in data processing. The results showed that the project generated an NPV value of Rp 221,248,788.21. This value reflects the positive added value of the investment made. Thus, the construction project of Sakura type houses is financially feasible. This investment is able to provide potential profits and a good return on capital. Based on these results, the Sakura type house in Chrysant Luxland Lamongan Housing can be used as a promising investment option, especially in the midst of the high community need for decent housing and continues to increase from time to time.

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.

Abstract

Delays in construction projects often lead to cost increases, reduced quality, and even the risk of penalties. This was the case in the Rehabilitation Project of the Regional Inspectorate Office Building of Tuban Regency, which experienced a 4.735% progress deviation in the 14th week. Such delays could affect the overall completion and increase project costs. This research aims to analyze the relationship between project time and cost using the Time Cost Trade Off method to find an efficient way to speed up the project. The study was carried out by collecting field data, analyzing the S-curve, identifying the critical path with the Critical Path Method , and simulating different overtime scenarios. From the three overtime options tested, adding 3 extra hours per day turned out to be the most effective choice. This scenario successfully shortened the project duration and achieved a 0.207% cost efficiency without causing significant changes to the work structure. This means that the application of the Time Cost Trade Off method is effective in optimizing resources, reducing the negative impact of delays, and maintaining a balance between time and cost in similar construction projects
