Abstract

This study sets out to analyze the total Life Cycle Cost (LCC) involved in constructing the Ndorurea 1 Village Office located in Nangapanda District, Ende Regency. Using the LCC approach, the research evaluates all expenses incurred throughout the building’s service life, which includes the initial construction costs, recurring annual operational costs, and scheduled maintenance costs over a span of 30 years. Data for this analysis were collected from the official Budget Plan (RAB), on-site observations, and interviews, and were processed using the Present Worth method. An inflation rate of 2.73% and a discount rate of 5.5% were applied to calculate the Future Value and convert it into Present Value. The findings reveal that the total LCC amounts to Rp 1,579,890,525.62, comprising an initial cost of Rp 784,461,207.31 (49.65%), operational costs of Rp 322,649,142.80 (20.42%), and maintenance costs of Rp 472,780,275.51 (28.92%). These results clearly show that more than half of the overall expenses are incurred after construction is completed. Hence, integrating the LCC approach from the initial planning stage is essential for ensuring cost efficiency, sustainability, and financial accountability in the development of village infrastructure.

Abstract

Traffic accidents remain a major issue affecting public safety worldwide. This study aims to analyze the relationship between the number of traffic accidents and the level of fatality on Sudirman Road in Maumere City. The research uses secondary data from the Sikka District Police covering the period 2019–2023, along with primary data from traffic volume surveys conducted in the study area. The analytical methods used include simple linear regression and correlation to determine the strength and direction of the relationship between the variables. The results show a fairly strong positive linear relationship between the number of accidents and the level of fatality, with a coefficient of determination (R²) of 0.6722. This means that approximately 67.22% of the variation in fatality levels can be explained by changes in the number of accidents. These findings indicate that an increase in the number of accidents is likely to be followed by a higher fatality rate. This research is expected to serve as a reference for improving traffic safety measures in urban areas. Keyword: traffic accidents, fatality rate, linear regression, Jalan Sudirman, Maumere

Abstract

This study aims to evaluate the use of lime as an alternative binder to replace cement in mortar mixtures, with the addition of crushed brick powder to enhance mechanical strength. This approach offers an environmentally friendly solution to the high carbon emissions associated with cement production. The mortar mixture was prepared using a ratio of 1:1:3 (lime : crushed brick powder : sand) with a water-to-binder ratio of 0.5. Tests were conducted to assess the compressive strength and density of the mortar at 7, 14, and 28 days of curing. The results showed that the average compressive strength increased with curing time, reaching 1.49 MPa at 7 days, 1.86 MPa at 14 days, and 2.40 MPa at 28 days. The mortar density ranged from 2,080 to 2,680 kg/m³, with average values of 2,513 kg/m³ (7 days), 2,342 kg/m³ (14 days), and 2,230 kg/m³ (28 days). These findings indicate that the combination of lime and crushed brick powder improves mortar performance and has the potential to be a more sustainable alternative construction material.
