Abstract

 Spring water is one of the natural resources that are beneficial to human life such as fulfilling the needs of clean water, irrigation, and others. Non-integrated spring management has the potential to create conflicts among water users, as is the case at Dukuh Blahkiuh Spring. The unbalanced fulfilment of water needs is felt by Subak Uma Poh farmers and other water users. Related to this, it is necessary to analyse the current availability of water and compare it with the needs and potential that can be developed. The utilisation of springs can be properly integrated if the water balance conditions are known in order to achieve fairness and appropriate proportions and avoid conflicts. The method in this research is quantitative analysis with variables of spring discharge, clean water needs, irrigation, and integrated water utilisation systems. This research shows that the potential water availability at Dukuh Blahkiuh Spring currently has an average discharge of 54.53 litres/second with a reliability level of 80%. The water balance condition that occurs is at the water surplus level with a percentage of 38.81%, which means that spring utilisation still has the potential to be developed. The integrated water service system is designed by prioritising the proportion of water use at 47.93% for clean water, 13.26% for irrigation and followed by other uses at 38.81%. Water balance analysis can illustrate the availability, demand and development potential of Dukuh Blahkiuh Spring, so that the integration of management systems can be done to increase its utilisation.Keywords: springs, water balance, water alocation

Abstract

 Pule District, Trenggalek Regency, East Java Province has only 42% of rice fields with irrigated status, and 58% of non-irrigated land. With the presence of a reservoir. the area of non-irrigated rice fields can be served and the planting indeks of rice fields can be increased. To be able to meet the target area of irrigated land diverted by reservoir, a hydrological and water balance approach is needed. The aim of this study is to analyze the water balance of reservoir to obtain the volume of water and the area of rice fields that can be irrigated each month. By using F.J.Mock to analyse water balance and calculate mainstay discharge. Evapotranspiration is calculated by Penman Modified method. The highest mainstay discharge Q80 is occurred about 3.25 m3/s in January, meanwhile the lowest is 0.22 m3/s in October. Reservoir capacity is determined from maximum volume based on height of reservoir. The height is 13.20 m which referenced to elevation 552.20 m.s.l. Maximum volume of reservoir is 56,437 m3. Analysis results show the highest inflow discharge is occurred in January about 7.46 million m3/month, the lowest in August about 0.45 million m3/month. Those condition of discharge if utilized for irrigation 11 Ha around 44,533 m3/month and raw water 2,560 people around 11,904 m3/month, so the reservoir is still in a fulfilled condition. The lowest inflow discharge can be referenced to determine maximum potential irrigation covered  area  into 112 Ha in dry season.    Keywords: reservoir, irrigation, water balance, water harvesting, land large

Abstract

 Rainfall plays a crucial role in shaping the weather in Indonesia, influenced by factors such as latitude, elevation, wind patterns, land and water distribution, as well as topography. Rising temperatures contribute to the increased intensity of extreme rainfall, amplifying the potential risk of disasters. Therefore, it is necessary to conduct analyses to predict weather based on historical time series data. This study aims to identify short-term rainfall patterns and trends using the SARIMAX method. The initial stage involves data processing and splitting the data into training data (2005-2014) and test data (2015-2019). Time series decomposition is then performed to identify patterns, followed by period identification and stationarity testing using the ADF test. The SARIMAX model is selected based on the lowest AIC value, followed by parameter estimation and diagnostic tests. Rainfall predictions are evaluated using model performance evaluation methods, while inferential statistics are used to describe population attributes through confidence intervals. The forecasting results show that using the SARIMAX (0, 0, 1)(0, 1, 1, 12)12 model for short-term rainfall prediction achieved the best performance with the smallest MSE, MAE, and MAPE values on the test sample with a 95% confidence level. Repeating rainfall patterns with a mid-year decline and significant variation in magnitude were identified from the sample data for August 2020-2027, with the lowest rainfall at 39.05 mm and the highest at 397.03 mm in December. The implications of this study support efforts to mitigate natural disasters due to unexpected weather changes by integrating this model into early warning systems and water resource planning.Keywords : hydrology, precipitation, time series, short-term, SARIMAX

Abstract

 The threat of water scarcity and the progressing technology in sewage treatment plants promote the reuse of recycled wastewater. While the practice itself is beneficial, there are still issues to be solved to utilize its full potential. This study focuses on identifying the bottlenecks or limiting factors in implementing the practice on a building scale. An office building was researched to reveal its water usage pattern. The building introduces a sewage treatment plant so the sewage can be recycled into usable freshwater. The analysis indicates the produced recycled wastewater has not been fully utilized until now. While the volume of the water demand is greater than the recycled wastewater, several factors hinder the total utilization of the reclaimed water. The recycled wastewater is mostly more than enough to cover the water usage for both gardening and toilet flushing, the usages still leave an excess of water for other purposes. Because of the constraints in water quality, finance, and public reception, the excess reclaimed water is yet to be optimally utilized. Firstly, the quality of the reclaimed water is not very convincing to be used for non-flushing human usage and cooling towers. Secondly, the high cost of the investment and the overhaul of the plumbing system (for old buildings) deters the practice of reusing the reclaimed water. Thirdly, many people still have terrible perceptions about reused wastewater thus they would hesitate to utilize it even if the reused water is technically fine.  Keywords: recycled wastewater, sewage treatment plant, office building, water conservation, rainwater harvesting

Abstract

 UB Forest Sumbersari is a forest for multidisciplinary research and development in Brawijaya University. In order to improve and reducing the environmental damage around the road due to water flow, the planned drainage system by implementing BIM. BIM has a major role in coordinating and integrating information exchange and knowledge between various disciplines and phases in the project implementation. In this study, the Autodesk Civil 3D and Autodesk Storm and Sanitary Analysis (SSA) are employed as a BIM platform. Autodesk Civil 3D is the latest version of AutoCAD Land Desktop development that has used the dynamic modeling concept. Autodesk Civil 3D helps facilitate in case of design changes as well as in the calculating of job volume such as the volume of cut and fill of the soil and volume of required materials in drainage channel planning. While SSA facilities plan on hydraulics such as flow depth, maximum velocity, channel slope, and channel dimensions. Based on the result of the SSA analysis, the dimensions of drainage channel are 30 cm x 30 cm, 50 cm x 50 xm, 65 cm x 65 cm, and 80 cm x 80 cm. And generated volume of cut equals to 3148,02 m3, while the volume of fill equals to  296,93 m3, with total required volume of gravel reaches 444,8 m3. Keywords:   drainage, Building Information Modeling, Autodesk Civil 3D, Storm and Sanitary Analysis,  UB Forest Sumbersari
