<![CDATA[Steel is a non-renewable resource, and its increasing scarcity raises construction costs. Bamboo, a natural and renewable material, presents an alternative. Research on bamboo-reinforced concrete shows that bamboo’s potential strength is yet to be fully realized. To improve bamboo-reinforced concrete performance, treatments are needed to enhance adhesion between bamboo and concrete and to strengthen the composite material. The addition of Ground Granulated Blast Furnace Slag (GGBFS) aims to increase the strength of bamboo-reinforced concrete. This research explores the flexural strength differences between bamboo-reinforced GGBFS concrete beams and steel-reinforced GGBFS concrete beams, identifying the optimal GGBFS mixture composition for bamboo-reinforced beams. Using an experimental method, bending tests are conducted following SNI 4431:2011 standards. The variable tested is the compressive strength with GGBFS and bamboo reinforcement added. Both types of concrete undergo flexural strength testing. Results indicate that steel-reinforced beams are generally stronger, but bamboo-reinforced beams with a 30% GGBFS mixture achieve a strength of 2.64 MPa, nearly matching steel-reinforced beams at 2.66 MPa (99.73% of the steel strength). This finding suggests that a 30% GGBFS mixture can make bamboo-reinforced beams a viable alternative to steel in concrete construction.]]>

<![CDATA[The development of urban areas is faced with increasing population and growth of building infrastructure which has a negative impact on urban spatial planning, such as the potential for flooding and inundation during the rainy season. One effort to overcome this problem is by implementing a sustainable urban drainage system in various forms of structures, including at the study location. This research aims to determine the capacity of existing drainage channels and determine alternative conservation-based flood management. The method used is to carry out hydrological analysis on the Tengger River Drainage Sub System and hydraulic analysis with SWMM 5.2 software for modeling rain runoff. The design rainfall simulation uses daily rainfall data from Suci station for 10 years (2009-2018). Model calibration using the RMSE method obtained a value of 0.053209. The modeling results found that 4 sections of existing secondary channels were at maximum capacity and overflowed with rain with a design return period of 5 years. Three alternatives were implemented at the study location, namely (1) rainwater harvesting and infiltration wells, (2) cross wave storage and (3) retention ponds. From the analysis, the most effective treatment in reducing flooding and more likely to be implemented was selected, namely implementing cross wave storage at 33 points. The eco-drain facility has a large enough storage capacity and a wider surface area to absorb water into the ground. Implementing a retention pond at the research location is difficult due to limited land, even though it reduces flood discharge better than other alternatives.]]>

<![CDATA[The Sago Plant in the Kais Region, South Sorong Regency, has significant potential as an alternative food source to rice. Currently, sago plant management remains traditional or non-technical, particularly in preparing water management requirements, specifically through technical drainage management for the Sago Plant. Generally, the local community indicates that efforts to improve sago plant management are constrained by drainage issues due to water conditions affected by tidal changes, which impact the root zone of the sago plants. Efforts to address these issues include the development of a Technical Drainage System throughout the sago plantation area. Therefore, this study aims to understand the application of a Technical Drainage System that will be implemented in the management of sago plants in the Kais Region, South Sorong Regency. This research involves analyzing both secondary and primary data available. The study begins with a literature review, data collection (including oceanographic data, topographic maps, and bathymetric maps), and field surveys (secondary data collection). All data will be used as input for the model and validated with satellite imagery and bathymetric maps. Based on existing river line changes and numerical model results, an analysis of river line changes and alternative drainage systems will be conducted as solutions for sago plant management]]>

<![CDATA[Sario River is located in Manado City and Minahasa Regency. The city of Manado is located on the northern tip of Sulawesi Island and is the largest city in the North Sulawesi as well known as the capital of North Sulawesi Province. The Geography coordinate is between 10o30'-10 o40' North latitude (N) and 1240 o 40'00" - 1260 o50'00" East Longitude (E). Floods of the sario river, that have occurred periodically and often have due to the capacity of the river that cannot accommodate the amount of flood discharge. Analysis of inundation in flood control ,aims to determine the extent and height of inundation that occurs due to flood overflow. Based on the results of the analysis of the maximum flood discharge obtained by the HECHMS method is 112,284 m3/dt. From these results it is obtained that the maximum discharge at the discharge observer point on the Sario/Ranotana river at the same time is 115,73 m3/det. To handle the situation that exist in the Sario river, a hydraulics analysis is carried out by simulating with HECRAS. There are several modeling scenarios that are analyzed including existing conditions, normalization handling and combination of normalization and embankments.]]>

<![CDATA[The research evaluates the time and cost performance of the Wu Tower Project in Bandung using the Earned Value (EV) method. The scope of the research includes a comprehensive literature study on the concept of Earned Value (EV) and its application in the evaluation of time and cost performance of construction projects. In addition, the research also includes the measurement of the actual time and cost performance of the Wu Tower Project using the EV method, analysis of influencing factors, especially those related to design complexity, scope changes, and labor, as well as comparison of actual time and cost performance with predetermined standards. The performance of the project implementation time in the 1st month (one) to the 8th month (eight) is progressing well as indicated by the SV (Schedule Variant) variant value is positive or the SPI performance index ≥ 1, this indicates that the work is progressing both in schedule and budget. For the 9th (ninth) to 11th (eleventh) month, the SV (Schedule Variant) value is negative, which means that the work is delayed, but the project completion expenditure budget is still quite efficient because the SPI value is ≥ 1. Based on the Performance Index value, the overall SPI value gets an average value of 1.73, which means that the project is progressing towards time performance, while the CPI value generally gets an average SPI value ≥ 1, which means that the costs incurred are more economical, so that the project is more efficient.]]>

<![CDATA[This research aims to analyze the influence of soil density levels on the California Bearing Ratio (CBR) value, which is one of the important parameters in road construction planning and design. This research was carried out using soil samples from several locations with varying levels of density. CBR testing was carried out in soil conditions with varying densities to evaluate the relationship between soil density and the resulting CBR values. The data obtained is analyzed using statistical methods to determine significant patterns or trends. The research results show that there is a positive correlation between the level of soil density and the CBR value, where an increase in soil density is associated with an increase in the CBR value. These findings provide important insights for road construction planning and soil quality assessment, and can be used as a reference in decision making regarding the selection and maintenance of soil materials for construction projects. The conclusion of this research is that increasing soil density can increase the CBR value, which in turn can increase the stability and bearing capacity of the soil in construction applications.]]>

<![CDATA[Cost and time efficiency are two crucial aspects that influence the success of a construction project. Conventional methods are usually used because they are considered more flexible and easily adapted to field conditions. However, the precast method is increasingly in demand because it is claimed to be more efficient and faster in implementation. This research uses a case study approach by collecting primary and secondary data from planned work. Cost data is obtained from the detailed cost budget (RAB), while time data is taken from the project implementation schedule (time schedule). The analysis was carried out by comparing the total costs and time duration between conventional and precast methods using the 2018 Bina Marga Specifications. The research results show that the precast method has advantages in time efficiency, with an average construction time that is shorter than conventional methods. However, in terms of costs, precast methods tend to be more expensive in the initial stages due to the high production costs of precast elements.]]>
