Abstract

Rivers play an important role in improving the welfare and quality of life of the Indonesian people. In addition, rivers can also cause flooding. The Waridin River is one of the rivers in the Kendal regency area. Flooding is an event where inundation occurs in a flat area around the river due to the overflow of water that the river cannot accommodate. To overcome the flood problem, the addition of parapets and the normalization of the river were carried out. For this reason, it is necessary to analyze the slope stability of the Waridin river from the excisiting conditions, design and construction conditions by paying attention to 3 (three) modeling conditions. The method used in this analysis is the Limit Equilibrium method, which utilizes software, specifically Geostudio, through the SLOPE/W menu. The analysis was carried out on existing conditions, planning, and construction. This analysis was carried out under normal conditions, earthquakes, and rapids. The results of the existing analysis were obtained that in the condition of the combination of earthquakes, the slope stability was below the safe factor, namely 1.02 < 1.2. sendang in other conditions tends to be safe. In the planning analysis by combining normalization and the addition of parapets with a 3-meter mini pile foundation, the results of all analysis conditions exceeded the value of the safety factor. Because at the time of construction a landslide occurred, a back analysis was carried out where the results of the back analysis were added reinforcement to the foot of the river slope with a mini pile of 4 meters with a distance of 1 meter each associated with the frame beams. The analysis results obtained show that it is safe for all implementation conditions.

Abstract

Infiltration wells are a form of hydrological infrastructure used to manage rainwater. Infiltration wells are usually built as part of a rainwater management system to soak rainwater into the ground and reduce surface waterlogging as well as slow down surface runoff and allow rainwater to seep into the ground to renew aquifers or prevent waterlogging. Maintaining groundwater levels is an important step in sustainable water resource management. The aim of this research is to plan effective infiltration wells to replace rainwater catchment areas lost due to building construction. The planning of this infiltration well uses the Sunjoto  method. From the research results, it was found that an effective infiltration well design was calculated using the Sunjoto  method. With the data, each roof area of ​​the house has an optimum number of infiltration wells with a planned infiltration well diameter of 1 m with a depth of 2.5 m with an effective depth according to the calculations is as follows: 60 m2 number of 1 unit of absorption well with an optimum depth of 2.82 m, 80 m2 number of 2 units of absorption well with an optimum depth of 3.76 m, 100 m2 number of 2 units of absorption well with an optimum depth of 4.7 m, 120 m2 number of 2 units of infiltration wells with an optimum depth of 5.64 m, 140 m2 number of 3 units of absorption wells with an optimum depth of 6.58 m, 160 m2 number of 3 units of absorption wells with an optimum depth of 7.52 m, 180 m2 number of 3 units of absorption wells with an optimum depth of 8.46 m, 200 m2 total of 4 units of infiltration wells with  an  optimum depth  of 9.4 m.

Abstract

Selection of concrete specifications is something that must be done according to needs. The use of concrete as a building material is efficiency and effectiveness in terms of processing and supply. The increase in fly ash and bottom ash waste will affect new innovations for new materials in construction. The purpose of this study was to determine the characteristics of the new material geopolymer binder course fly waste and bottom ash whether it complies with standards and is suitable for use as a construction material or for making roads. This research was carried out experimentally in the laboratory to check whether the characteristics of the material used met the standards or not. The results obtained were that the best mixture for the new material was between (FA+BA) with a compressive strength of 5.15 MPa and (FA+PS) with a compressive strength of 25.6 MPa at 28 days old with a mixture composition of 1 : 1.5. As for the mixed wear value (FA+BA) has a wear value of 76% while (FA+PS) has 39% wear. The new material resulting from the wear level can be used as a base course material.

Abstract

Floods are natural disasters that often occur in various parts of the world, especially in flood-prone areas. Floods occur when water from rivers, lakes or seas overflows beyond its holding capacity. Floods can cause great damage to infrastructure, plants, animals and people. To overcome floods that occur frequently every year, it is necessary to map areas prone to flooding accurately and quickly using GIS which can be used to accurately monitor the location and area of ​​the area that is experiencing flooding. This study aims to analyze flood-prone areas and compile maps of flood-prone areas and describe the conditions of flood-prone areas in Bojonegoro Regency based on Geographic Information Systems (GIS). Data processed using GIS include: RBI Map of Bojonegoro Regency, River Map, Soil Type Map, Rainfall Data, Landsat Imagery Data, Flood incident data in Bojonegoro Regency. From the results of data processing, the results of the analysis are as follows: The level of flood-prone areas in Bojonegoro Regency is divided into 3 classes, namely: very vulnerable class of 49,963.671 Ha or around 21.66% of the sub-districts in Bojonegoro including the District: Margomulyo , Ngraho, Padangan, Kasiman, Malo, Purwosari, Trucuk, Kalitidu, Ngasem, Bojonegoro, Kapas, Dander, Balen, Kanor, Baureno, Sumberrejo, Kepohbaru and Gondang. The vulnerable class of 173,162.171 Ha or around 75.05% is in sub-districts including: Margomulyo, Ngraho, Tambakrejo, Kedewan District, Malo, Trucuk, Sekar, Ngambon, Ngasem, Gondang, Bubulan, Dander, Temayang, Sugihwaras and Kedungadem. The non-prone class is 7,580.157 ha or 3.29% in the sub-districts including: Margomulyo, Ngraho, Tambakrejo, Kedewan, Malo, Trucuk, Sekar, Ngambon, Gondang, Temayang, Sugihwaras and Kedungadem. Areas that have a high level of vulnerability are around the Bengawan Solo River which crosses Bojonegoro Regency. This can be caused because the area around the Bengawan Solo River has a height of <25 m and frequent flooding from the upstream and tributaries of the Bengawan Solo River.

Abstract

Porous geopolymer concrete has gained attention as a sustainable and environmentally friendly alternative to conventional Portland cement-based concrete, utilizing industrial waste such as fly ash. This study investigates the effect of aggregate gradation variations on the mechanical properties, porosity, and sustainability of fly ash-based porous geopolymer concrete. The experimental method was employed, utilizing fly ash as the primary binder, sodium hydroxide (NaOH) as the activator, and coarse aggregates of varying sizes (3/8", 1/2", and 3/4"). The concrete samples were tested for compressive strength and porosity at 7, 14, and 28 days following ASTM standards. The results indicate that aggregate gradation significantly influences the mechanical properties, porosity, and sustainability of geopolymer concrete. Smaller aggregate sizes (3/8") produced higher compressive strength (5.42 MPa at 28 days) but lower porosity, while larger aggregates (3/4") increased porosity but reduced compressive strength. Additionally, the study confirms that geopolymer concrete using fly ash as a binder meets the standard requirements for setting time, specific gravity, and durability. These findings contribute to optimizing porous geopolymer concrete for sustainable construction applications, particularly in drainage and permeable pavement systems, promoting waste utilization and environmental sustainability.  Keyword: Porous geopolymer concrete, fly ash, , porosity, waste, sustainability

Abstract

Utilizing dead rock as a cement additive in the manufacture of paving blocks, and the rock contains CaCO3 which includes limestone as in the content of cement which has lime content (CaO), the aim is to determine the effect of rock on the compressive strength value of paving blocks. Utilization of stone in the manufacture of paving blocks using a mixture of design 0%, 5%, 10%, and 15% of the weight of cement to be used. Manufacture of paving blocks using a ratio of 1: 3 sand cement, cement water factor 0.4 with molds 20 x 10 x 6 cm, compaction weight of 1 paving 3.52 kg and testing compressive strength at 7, 14 and 28 days, using the method (SNI 03- 0691-1996) paving block. From the analysis of compressive strength testing, it was found that the compressive strength of paving blocks increased towards normal paving blocks to produce the highest compressive strength with added rock in the 15% variation at the age of 28 days, which amounted to 45.1 MPa and included the quality of class A paving blocks with SNI 03-0691 (1996) standards. The compressive strength of the 5% variation at 28 days of age is 38.7 MPa and the compressive strength of the 10% variation at 28 days of age is 43.5 MPa. It can be seen that coral stone as a cement additive is able to improve the quality of compressive strength of paving blocks.
