Abstract

Despite implementing many recharge wells, the groundwater recharge with wells is still minimal. The hydrostatic pressure of the recharge well is only experienced at the bottom of the well which caused surface runoff. This study aims to formulate water recharge with Type T Perforated Horizontal Recharge Pipes (PHRP-T) to analyze the need for reducing surface runoff discharge. Water recharge with PHRP-T is greater than recharge wells. Using the experimental method, the recharge test was carried out with the independent variables of soil permeability (K), pipe wall porosity (P), pipe diameter (D), the length of the perforated horizontal pipe (L), and water pressure level (H). The recharge was observed from lowering the water level in the vertical pipe PHRP-T. A statistical program was performed to analyse the relationship between water absorption (Q) as the dependent variable with a regression equation. PHRP-T implementation to reduce surface runoff discharge can be applied to the hydrograph and rational methods. The findings of PHRP-T are significant for reducing flooding and increasing groundwater availability.

Abstract

Construction made from concrete, both conventional concrete and Self Compacting Concrete (SCC), which contact with seawater, often run into decreased durability due to the content of chemical compounds that are harmful for concrete, such as Magnesium Sulfate (MgSO4) and Chloride (Cl). One way to overcome this problem is to use fine fly ash in the concrete mixture. This article discusses the results of an experimental study on the use of fine fly ash in High Volume Fly Ash- Self Compacting Concrete on durability and mechanical properties. Fine fly ash used is processed using the fly ash filtering method with a water filter. The research method is a laboratory experiment by making concrete test objects. Durability tests include Volume of Permeable Voids (VPV) and Rapid Chloride Penetration Test (RCPT), while mechanical properties is concrete compressive strength. The research results showed that using fine fly ash compared to concrete without fly ash or concrete with raw fly ash positively impacted increasing compressive strength, reducing concrete voids, and good resistance to chloride attack at low penetration levels.

Abstract

In recent years a number of areas in the country have experienced earthquakes, resulting in deaths and damage to buildings. Indonesia is located in the Pacific Volcano Rim and is a country with the most active volcanoes in the world, so earthquakes often occur. In this thesis, a comparative analysis of the use of Base Isolators in an 8-storey building and a case study of Semarang Public Works Polytechnic Flats is conducted. The analysis uses ETABS V18 Software. The Vibration Period of the 8-Storey Building without Base Isolator in the X direction is 0.597s and when added Base Isolator becomes 2.099s Reduction of 58% while the Vibration Period of the 25-Storey Building without Base Isolator in the X direction is 2.65s and which has been given a Base Isolator of 2.902s Reduction of 8,7%. In conclusion, the higher the building, the smaller the Reduction Rate or the less useful the use of Base Isolator.

Abstract

The city of Pontianak has the longest river in West Kalimantan, namely the Kapuas River. This river is used by the majority of Pontianak City residents in their daily activities, including the West Pontianak District area. As a result, river water quality can change over time. Many influencing factors, such as human activities, are thought to cause the lake's water quality to become low. One way to control pollution in an ecosystem can be done by monitoring water quality over a certain period of time, so that the water quality status is known. Based on the description above, it is currently important to carry out an article regarding analysis of water quality distribution maps and water quality status in the West Pontianak District area. This article aims to analyze the level of pollution and how widespread the water pollution is in the West Pontianak District, Pontianak City by carrying out mapping based on water quality data using a Geographic Information System (GIS). The results of this research are that on the 2019, 2020 and 2021 distribution maps, analysis was carried out for 7 parameters, namely BOD, COD, Nitrate, PH, Temperature, TDS and TSS values. These 7 parameters show mutually supporting results that based on the distribution map, it can be seen that the water quality in the West Pontianak District area still seems safe for people to use for their daily activities. Even the Nitrate, PH, Temperature, TDS and TSS values appear to have increased from 2019 to 2021. This shows better water quality than the previous year. In 2020 and 2021 there are 2 additional parameters, namely DO and Phosphate and in 2021 there is a fecal coliform parameter. These three additional parameters also support the results of the previous 7 parameters. It can be seen that good changes have occurred in the water quality in the West Pontianak District area. The DO and phosphate distribution map show changes in values from 2020 and 2021, which shows that the water quality in the area is getting better. The fecal coliform distribution map shows that only a few points are contaminated with the feces of living creatures.

Abstract

A 20-story building located in Bandung, with a height of 70.5 m, functions as both an office building and an apartment complex. As a high-rise structure, seismic analysis of the building is required to determine the seismic pattern using the response spectrum method. The response spectrum method is used to compare V-static with Vdynamic based on SNI 1726-2019, and to determine the structural performance of the 20-story building frame. The results obtained for each frame using a combination of cases (static + seismic) show that, for displacement review, the highest shift occurs on the 20th floor at 1003.27 mm, and the highest drift value is on the 9th floor at 125.92 mm. The internal forces on the sample column show the highest results on the 5th-floor column C1 with 1.07x105 kN for Fx, 1.95x103 kN for Fy, and a moment of 5.44x103 kN-m, through the combination (static + seismic). Meanwhile, for the reviewed beam forces, the highest values are found on beam B53 on the 6th floor with an Fx value of 80.23 kN, Fy of 3140.53 kN, and the largest moment on the 15th-floor beam B53 of 793.46 kN-m.

Abstract

BPS West Bandung Regency in 2021 recorded a population of 1,181,226 people with an annual growth rate of 1.65%, with a growth rate that continues to increase every year, the need for housing in West Bandung Regency is increasing. Therefore, KPRI Universitas Pendidikan Indoensia plans to build housing, namely Graha Isola Housing to meet housing needs in West Bandung Regency, especially in Pasirhalang Village, Ciasarua District, West Bandung Regency. Housing development requires suitable land so it is necessary to evaluate land conditions and the level of disaster vulnerability because the housing site is located in an area with the potential for landslides. The research used descriptive qualitative and quantitative methods. The data used include National Digital Elevetion Model (DEM) data, Rupa Bumi Indonesia (RBI) Map of West Bandung Regency, Soil Type, Rock Type, rainfall data, West Bandung Regency RTRW Map and other literature sources. The results showed that the land suitability at Graha Isola housing site is in accordance with the land use conditions in the field, namely non-residential land so that residential development can be carried out. And the level of landslide hazard at the housing site is in a low hazard level, so that development can be carried out. However, housing development must also be adjusted to the aspects of livable housing development criteria.

Abstract

Beam-strengthening innovations need to be developed considering the frequent occurrence of earthquakes in Indonesia to avoid structural failure. One of the innovations in strengthening existing beams is strengthening by expanding the beam support area. This research aims to determine the behavior of strengthening existing beams. The research methods used are theoretical analysis and finite element analysis. Theoretical analysis and FEA show that strengthening the P1 beam can increase the bending and shear moment capacity by more than 50%. FEA analysis shows that retrofitting of the P1 beam increases stiffness by 45%. Strengthening the P1 beam is also able to avoid failure at the beam-column connection.
