Assessment of Water Supply System Performance Indicators Based on the Customer Bill-Based Approach
Get PDFSignificant efforts have been undertaken over the last two decades by governmental organizations and local and international non-governmental sectors to improve water supply and sanitation structures; however, there are significant challenges to the town\u27s growth and expansion. Chiro town\u27s population is increasing, and the community is affected by water and excreta-borne diseases as a result of a lack of proper sanitation facilities and a water supply system. In this study, billed data from Chiro Town water supply service enterprise customers have been used to assess the performance of the water distribution network over ten years (2011-2020). The findings show that the Town\u27s water coverage is 62.9%, the water demand is 8,121.6m3/day, and the computed annual water production is 4,222.3m3/day. Residents of the town have complained about a lack of access to improved drinking water supplies, low water consumption, and sanitation facilities, particularly in the community of those who live in the town\u27s borders and practice open defecation. For all domestic use, 16.32% and 83.68% of respondents used unprotected and protected water sources, respectively. This study suggested that strong sectoral coordination, community involvement, and sufficient financial resources were required to identify the root causes and provide an efficient water supply system in the study area
Prediction of changes in land use/land cover and hydrological response in the Upper Ciliwung Watershed
Get PDFAs a result of rapid urbanization, in 2021, it was recorded that the forest area in the Upper Ciliwung Watershed was only a quarter of the total area. Therefore, the Upper Ciliwung Watershed cannot optimally perform its hydrological functions. One of the reasons for conducting this research is to provide consideration in calculating the adequacy of the forest area in the Upper Ciliwung watershed. In addition, this research was also conducted to estimate the discharge and volume of water, the trend of land use change in the Upper Ciliwung watershed in the last few decades, what might happen in the future if land use change continues, and how much influence it will have in maintaining forest areas that exist in minimizing the risk of future disasters occurring due to the high rate of development. This study combines remote sensing technology and hydrological modelling to understand changes in hydrological characteristics when LULC transformed from 2001 to 2051. The spatial-temporal dynamics of LULC and its hydrological response were estimated using an integrated approach that combines remote sensing, Cellular Automata-Markov Chain based on Multi-Layer Perceptron with an HEC-HMS modelling system. Multitemporal satellite imagery is used to understand LULC changes and projections for 2031 and 2051 in the Upper Ciliwung watershed. The analysis shows that there has been a very significant increase in the developed area over the years. In contrast, other types of LULC have decreased. In 2001-2051, the forest area experienced the worst decline, 22,423,493 m2. Meanwhile, the developed area experienced a significant increase of 49,771,952 m2. This changing pattern has a negative impact on hydrological characteristics. Hydrological modelling shows that the volume and discharge are projected to increase drastically to reach 258.61 x 106 m3 and 26.3 m3/s, respectively, in 2051
Lanting House preservation based on river culture in Sasirangan Village, Banjarmasin
Get PDFThe shift in time has brought about changes that clearly leave the cultural identity of the archipelago. Sasirangan Village is one of the villages located in the middle of Banjarmasin City. This village still has a strong atmosphere, especially in the diversity of architecture in the area. River culture is still visible in this village, both for daily needs and also land for housing, namely Rumah Lanting. There are 3 Lanting houses in Sasirangan Village. The lack of a number of Lanting Houses left at this time raises a concern that there is a threat of extinction from cultural heritage. In this case, it is necessary to have a study of the architectural concept of the Lanting House to determine the right steps in preserving the Lanting House. The results of this study found that the right effort to preserve the Lanting House in Sasirangan Village was a revitalization effort that did not require material replacement and developed it as a Sasirangan gallery or souvenir shop that supports local wisdom and the identity of Sasirangan Village
Comparison of Formwork use in Building X Project in Surabaya City
Get PDFThe Value Engineering method is a method that analyzes the problems of a project through a systematic and organized approach by eliminating unnecessary costs without reducing the function, appearance, quality, and reliability of the project. The object x building, which has an estimated project value of IDR 42,812,329,371 in structural work. With the estimated value of the work costing a lot, it is, therefore, necessary to make efforts to streamline costs by using the value engineering method; this study aims to choose an alternative material for it. This research method uses a Pareto chart to find the highest work value. The results of this study indicate that the beam work is priced at IDR 15,088,457,899, floor plate work of IDR 12,530,471,281, column work of IDR 10,228,438,679. The results of the analysis of alternative structural calculations using semi-system formwork and full system formwork, which initially used conventional formwork, were simulated using alternative 1, namely semi-system formwork,k and by using alternative two full system formwork. The two alternatives are applied to column, beam and floor plate formwork. So, for this building, it is recommended to replace formwork because the conventional formwork used in this building incurs a large enough price, it is necessary to save on beam parts, and it is recommended to use full system formwork because the cost of beam formwork using full system formwork is IDR 134,950 per square meter. For the floor plate formwork, it is recommended to use a full floor plate formwork system because the cost per square meter is IDR 202,360. And for columns, it is recommended to use full system formwork because the cost of column formwork if using full system formwork is IDR 115,290. And from the use of all the full-system formwork for structural work, a total cost of IDR 40,312,992,291.32
An Alternative Model to Estimate Total Suspended Solids Concentrations using Landsat 8 Imagery in Indonesia
Get PDFA regular monitoring program of water quality is generally performed using a direct measurement method, which requires substantial efforts and resources. These issues can be minimised using several options, one of which is Landsat 8 (L8). This imagery has been broadly used to measure several water quality parameters, especially Total Suspended Solids (TSS) concentrations, even in Indonesia. This paper will compare several models from previous studies and a modified model generated using data from various sites. The comparison is based on their competencies to estimate TSS concentrations. The competencies are determined by the coefficient of correlation (r), correlation of determination (R2), and residual standard error (RSE) parameters as these three parameters are strongly correlated, generally applied, and provide distinctive determinations. The best model should have the highest r and R2 values, while the RSE value should be the lowest. The results imply that TSS model 4 generated in this study provides comparable results with TSS model 1, which has been generally used in Indonesia and provided favourable results. Thus, it can be an alternative model to estimate TSS concentrations in Indonesia
Relationship Between Soil Physical Characteristics and Infiltration Rate of The Practice Area of SMK PPN Banjarbaru
Get PDFThe practice area for the Banjarbaru State Agricultural Development Vocational School (SMK PP N Banjarbaru) is located in Kemuning Village, South Banjarbaru District, Banjarbaru City, South Kalimantan Province. Regarding the land use in the research location, the majority is used for plantation land, which is one of the lands suitable for water catchment areas in Banjarbaru City. The Practice Land of PP N Banjarbaru Vocational School is one of the models of good catchment area land from good land use and irrigation systems. Conducted this analyze the infiltration rate and its influence on the physical properties of the soil. From the results of the infiltration test using a double ring infiltrometer which was then analyzed using the Horton method, the most considerable infiltration rate was in open land, namely 33.83 cm/hour, rubber plantations of 22.57 cm/hour, on palawija land it is 15.57 cm/hour and on mahogany land, it is 14.47 cm/hour. From the results of the analysis using the linear regression approach, the physical properties of the soil that can affect the infiltration rate include 16.7% bulk density, 75% permeability, and 90% moisture content. Meanwhile, particle density and porosity only affect 0.7% and 3.5%
Evaluation of accessibility commuter-line station with jitney transportation modes by using GIS application: a case study of Depok Station
Get PDFThis research aims to evaluate the aspects that can increase the Station\u27s service area by maximising the integrated Jitney as the other public transportation modes that can increase reachability for the people near the Station. Evaluating the accessibility of some stations in the Depok area is needed to identify the infrastructure upgrading priorities, such as providing pedestrian roads and giving better access to the Station to increase the Station\u27s service area. The methodology used in this research is analysing method using a GIS application to assess and discover the pattern of travel behaviour for public transport in the Depok municipality area. The GIS Database Design in this research uses the Spatial Database and Attribute Database, which are integrated with the QGIS application to become Maps for the service area of public transportation in the Depok Municipality. The road network in Depok municipality is dominated by the jitney route as intracity public transportation, which travels on the arterial and collector road. Then the railway is located in the central area of Depok that stretches from South to North. There are some areas that do not have access to jitney services due to this residential area being far from the arterial and collector road travelled by Jitney. Looking at its planning for jitneys in the Depok area, the availability of jitneys follows the demand of the passenger population, and there are no travel analyses from the Transportation Department of Depok Municipality or local public transport organisations (ORGANDA) as private jitney operators. The ineffective jitney route planning is the other reason that there are some uncovered residential areas from public transport access. Subsequently, there are different travel time characteristics among four commuter line stations in the Depok Municipality area. The Citayam and New Depok Stations have wider access for pedestrians which these two stations have a more extensive service area than Old Depok Station, whereas Old Depok Station has restricted access to the west area of this Station. The rearrangement of the Station access is needed, especially for Old Depok Station, by adding road access on the west side to increase the service area of the Station
Priority Mapping for Handling Environmental Road Using GIS in Gerung District, West Lombok Regency
Get PDFImproving road access is very important to support human activities. One of them is improving the quality of environmental roads in Gerung District, West Lombok Regency. To make it with the availability of funds which cannot cover the entire segment in one time, that’s why priority handling is needed. This paper intends to determine the number of environmental roads in Gerung District; to know the priority of handling with SDI survey; and create a handling priority map using GIS. Based on the results, it was found that the number of environmental roads in Gerung District was 987 sections spread over 11 villages and 3 sub-districts. Handling priority of environmental road determined by the classification of road conditions as follows: good, medium, lightly damaged and heavily damaged. The number of roads based on this classification are: 568 segments for good condition; 131 segments for medium conditions; 200 segments for lightly damage; and 88 sections for heavily damaged conditions. In the map, each road segment assigned with colour identity according to its conditions and handling priorities using QGIS. The colour identities are: yellow for good condition; orange for medium conditions; red for lightly damaged conditions; and maroon for heavily damaged conditions.
