Abstract

Floods around the Bendung River in Palembang City have caused material and non-material losses. One of the reasons was the decreasing river capacity and backwater during the Musi River flood season, which is the Bendung River's outlet. This paper discusses the impact of adding a pump system to reduce flood impact. 1-dimensional and 2-dimensional numerical model using MIKE 11 and MIKE FLOOD were made to analyze the best measures. Various alternative scenarios were implemented in the model. Based on the modeling results, using the most optimal alternative, alternative 4 with 6 pumps of 36 m3/s and normalization of the Bendung River channel by 1 meter. The inundation area was reduced by 0.74 km2. Also, the maximum inundation height for the flood decreased by 0.6 meters, and the inundation duration was reduced by 8.5 hours. These modeling results can be a reference for managers and policymakers in managing flood events.Keywords: River channel normalization, pump system, numerical model, flood control, Bendung river

Abstract

Truss light steel is a modern technology of roof truss made of a thin plate of zinc-alum which is designed by computers and manufactured by machines. Truss light steel can be an alternative choice to support the roof to be able to deal with the extreme weather conditions, not to be distracted from termite attack and to be held longer than truss form wood. From its material, there are some weaknesses of light steel, among other are buckling and deflection occurs, so that a review was made of the failure that will occur in some spans and truss forms.  SolidWorks is a Computer Aided Design (CAD) 3D program using the Windows operating system. SolidWorks program can provide the simulation and compute the forces that arise in structures which designed by using finite element method. The use of SolidWorks program shows the simulation of failure mode that will occur, so it can be the input for the planning and construction of the better light steel. This analysis used the truss of type pratt and howe with theoretical spans 12 m and 24 m at 300 angle. The components used were profile lip channel 75x32.8x7.95 and tek screw formed in SolidWorks program. The results obtained in the SolidWorks program was the failure occurred because of flexural buckling in A6 rod to the entire spans and forms. Truss pratt type was stronger to resist the loads on the theoretical span of 12 m and the  howe type was stronger to resist the loads on the theoretical span 24 m. Diagonal mounting differences affected the strength of each spans. Key Words: truss, light steel, SolidWorks, failure mode

Abstract

Flood is triggered by a decrease in catchment areas due to an increase in population, activities, and land requirements, both for settlements and economic activities. The flood occurs annually during the wet season at downstream of the campus of Sriwijaya University. In 2019, the downstream swampy land of about 100 ha was excavated and functioned as a retention basin or small reservoir called Embung. The reservoir at Taman Firdaus, Sriwijaya University, was designed by using spillway's top elevation at +5.00m. The objective of the research was to analyze the effectivity of the reservoir on the flood water level of the Kelekar river. One dimensional modelling was used to model the hydraulic routing through small reservoir and Kelekar river. Based on the results of the modeling, it can be seen that the reservoir at Taman Firdaus Universitas Sriwijaya could hold water as much as 1.446.409,39 m3, and lower the flood water level in the Kelekar River by approximately 1 to 1.5 meters.

Abstract

A complete watershed management solution and logical outcome is a watershed approach that takes into account watershed capabilities, such as environmental services in the fields of water management and flood prevention. With integrated planning and environmentally responsible, policy-based drainage, floods can be overcome. For spectators and scholars, the topic of flooding has long been of interest as they try to understand its causes and effects. According to studies done by earlier researchers, the city of Palembang has recently been particularly vulnerable to floods, thus it is important to investigate the priority scale of flood control examined for all states in the Palembang city water catchment area. Surveys, field observations, measurements, and documentation are used as the main collecting tools, whilst study location maps are used for secondary data. The SWOT analysis method of scoring is used in the city of Palembang's priority analysis of flood management. According to the analysis's findings, the Bendung, Sekanak, and Buah watershed sub-systems have the greatest priority scales due to their extremely high priority values in comparison to the other watershed sub-systems. The Gandus watershed sub-system, the Gasing watershed sub-system, and the Aur watershed sub-system are the three least important watershed sub-systems that are not yet given priority.

Abstract

In Indonesia, 39 watersheds were deemed essential in 1994, and the importance of watersheds grew in 2000. The existence of a watershed has the role of being able to sustain water availability, maintain the balance of the ecosystem and as a container for flowing water. The Musi-Sugihan-Banyuasin-Lemau River Area (WS MSBL), which has an area of 86680 km2 and is made up of 23 primary watersheds, is one of the largest watersheds in the Sumatra region. Research was done to determine the state of the watershed so that a strategy for watershed conservation could be chosen. In-depth interviews with stakeholders in the form of focus group discussions (FGD) were utilized as the study method to collect both secondary and primary data about the circumstances of the watershed as well as to gain in-depth management outcomes. The study's findings demonstrate that managing the WS MSBL watershed involves more than only technical issues; it also necessitates involving associated institutions and stakeholders, necessitating the creation of operational watershed management strategies.

Abstract

The latest advances in science and technology have positioned nanomaterials at the vanguard of contemporary research. Nano silica (SiO2) is an illustrative example of a nanomaterial extensively utilized in concrete manufacturing due to its properties as a pozzolan. The objective of this study is to elucidate the characteristics of nano silica and its effect on the performance of polymer concrete through experimental methods. X-ray diffraction (XRD) tests indicate that nano silica exhibits a high amorphous phase. Consequently, nano silica enhances the C-S-H gel formation reaction, producing more robust and denser specimens. The maximum compressive strength reached 45.23 MPa when adding 0.4% nano-silica with a specific gravity of 1573.33 kg/m3. For comparison, concrete without nano silica had a maximum compressive strength of 40.05 MPa with a particular gravity of 1610.67 kg/m3. Observation using a scanning electron microscope (SEM) showed that the nano-silica mixture exhibited excellent particle distribution as an activating agent that could enhance the strength of the specimens. Nevertheless, the observed reduction in compressive strength might be affected by several factors, including particle clusters and the presence of compounds carried by the fine aggregates that influence the mechanical properties of polymer concrete. Integrating nano-silica is pivotal in enhancing the compressive strength and reducing the specific gravity of polymer concrete specimens. The increased strength and decreased specific gravity render nano silica a promising additive for polymer concrete applications.

Abstract

Fly ash, a byproduct of coal combustion, has gained significant attention due to its high silica content, and this silica-rich waste can be effectively converted into nano-silica. Factors such as the molarity of the solution, liquid-to-solid ratio, and the aging time play an essential role in determining the characteristics of silica nano produced, including particle size, morphology, and purity. This research aimed to determine the optimal conditions of solution molarity and the liquid-to-solid ratio to produce high-purity nano silica, examine the effect of aging time on the morphology and size of silica nanoparticles, and evaluating the effectiveness of the sol-gel method in producing nano-silica. This research uses nitric acid (HNO3 3 M) as the solution because it has not been widely explored and is more effective than other acidic solutions. In addition, the liquid-to-solid ratio varied from 1:5, 1:10, and 1:15, and combined with an aging time of 9 and 12 days, this study became the focus. The sample tested included XRD, XRF, FTIR, and SEM to confirm the nano-silica characteristics. It shows XRD is in the range of 2θ of about 20-22◦, which indicates the presence of amorphous silica, and FTIR shows results that support XRD data. SiO2 composition ranges from 97.47% to 98.57%, a very high amount of pure silica. It may concluded that silica nanoparticles have a particle size that varies from 151.2 nm to 295.4 nm, with a smooth morphology and relatively well distributed.

Abstract

In the era of globalization, regional improvements can be seen through infrastructure development which is one of the important and essential aspects to accelerate the development process of a country and region. The central and regional governments continue to expand infrastructure throughout Indonesia every year. Infrastructure not only concerns the development of the transportation sector such as the construction of roads and bridges, but also basic service facilities in other sectors such as the business world, education, and health. The problem of poverty can be overcome by having infrastructure that supports the local community which can be done in the form of cooperation between business entities, this is stated in Presidential Regulation of the Republic of Indonesia Number 38 of 2015. The purpose of the study was to analyze the effect of the development of road, health, education and clean water infrastructure on poverty rates using correlation analysis and multiple regression analysis. The data obtained came from the Central Statistics Agency of PALI Regency from 2019 - 2023. The data will be analyzed using a descriptive and quantitative approach, namely explaining the trends that occur. The results of the study showed that the variable that greatly influenced the poverty rate was the human development index (HDI) with a Pearson correlation of 0.970 and a multiple regression coefficient of 0.448.
