Abstract

Development in Bandar Lampung is increasing rapidly, causing an increase in transportation development. The development of transportation in the city of Bandar Lampung is currently still experiencing severe problems, so traffic hours often occur. The high level of congestion on the highway is caused by several things, including the unbalanced road capacity and vehicle volume and the presence of side obstacles, which add to congestion on the Z.A. Pagaralam road section. Apart from being a public road, Pagaralam is also located in one of the busiest economic centers in the city of Bandar Lampung. Along this stretch of road are campuses, schools, shops, pharmacies, shopping centers, and street vendors, and it is also a transfer point for passengers moving from one public transport to another, causing many side obstacles to occur on the road. To overcome this, it is necessary to analyze the influence of side obstacles on traffic performance. Data analysis was carried out using the PKJI 2014 method. The analysis of traffic volume obtained a value of 4747.75 cur/hour. The analysis results of the highest side obstacles were obtained on Tuesday at 12.00 – 14.00 segment 1 amounting to 838.90 incident weights. Keywords: Traffic Volume, Side Obstacles, PKJI 2014.

Abstract

The need for decent housing in Indonesia increases along with population growth, but the subsidized housing program still faces infrastructure problems that affect occupant satisfaction. This study analyzes the satisfaction of occupants of the Pane Residence 99 Housing using the Customer Satisfaction Index (CSI) and Importance Performance Analysis (IPA) methods. A descriptive quantitative approach was applied with a sample of 52 respondents through a Likert Scale questionnaire. The results showed a satisfaction index of 59.42% (quite satisfied). The IPA analysis revealed that 42.11% of attributes fell into Quadrant A (priority for improvement), such as drainage, clean water, health facilities, and roof-ceiling quality. As many as 10.53% of attributes fell into Quadrant B (maintain), such as road conditions and worship facilities. Recommendations include routine repairs to infrastructure and improving building quality. This study provides input for developers and the government to improve the effectiveness of the subsidized housing program.

Abstract

Fiber concrete is an innovation in concrete technology that utilizes additional materials in the form of natural or synthetic fibers to improve its mechanical characteristics, such as tensile strength, crack resistance, and ductility. In this study, K150 grade concrete was used with four variations of bamboo fiber addition: 0% (as a control), 0.5%, 1%, 1.5%, and 2% by weight of cement. Compressive strength tests were conducted at 14 and 28 days. The results showed that the addition of bamboo fibers consistently increased the compressive strength of the concrete. This increase was associated with better bonding between the aggregate and cement paste, which increased the density and strength of the material. At 14 days, concrete without fiber achieved a compressive strength of 10.57 N/mm², while concrete with 2% bamboo fiber achieved 15.94 N/mm². At 28 days, the respective values were 12.91 N/mm² and 17.85 N/mm². The average increase was 26.15% compared to the control concrete. Further research is recommended to explore higher fiber content and the use of various types of bamboo to evaluate the comparison of compressive strength performance. This study contributes to the development of environmentally friendly concrete by utilizing sustainable local materials.
