Abstract

Population growth and regional development in an area cause water needs to continue to increase because the fulfillment of food needs and population activities are always closely related to water needs. One of the water providers used by the community is a reservoir. Saguling Reservoir is a reservoir located in Saguling Village, West Bandung Regency, West Java Province, which has several benefits such as providing drinking water, irrigation, flood control and tourist attractions. In this Final Project, it was discussed about the availability of water in the Saguling Reservoir by conducting research in the form of water balance analysis. The purpose of this study is to provide an overview of water availability in Saguling Reservoir by considering inflow from rivers, outgoing discharge, rainfall, and evaporation using 2022 data. The results of the water balance analysis show that the water availability of Saguling Reservoir can meet water needs for various purposes every month in 2022. Further water balance analysis by considering seepage and infiltration that occurs in Saguling Reservoir. Keywords: balance of water, discharge, precipitation, evaporation.

Abstract

Indonesia, which is known as a country with a tropical climate and is traversed by the equator, causes the country to have quite high rainfall. Flood problems often occur in Indonesia, especially in big cities, including the capital city or the city of Jakarta, which is one of the cities that is often hit by floods. The purpose of this experiment is to see whether the vegetation on the soil affects the coefficient C of the runoff and flow rate that occurs. Zoycia Japonica grass species has adequate infiltration capacity. The first scenario is that the infiltration results obtained from the practicum are not much different from the calculation results without grass or soil media. The results of the calculation have results for the first minute 6.67 ml, the second minute 13.3 ml, the third minute 20 ml, the fourth minute 26.67 ml, the fifth minute 33.37 ml. As for the results of the first scenario practicum, the results for the first minute were 6.3 ml, the second minute 12.88 ml, the third minute 19.87 ml, the fourth minute 26.33 ml, the fifth minute 32.99 ml. For the first scenario, the value of the coefficient C also has a value of 0 which means that no rainwater will run off on the surface. For scenario 2, zoycia grass also still shows a good coefficient C, which can be seen from the total runoff discharge, which is only around 4.16 ml/minute and has a coefficient C value of 0.6933. Keywords: Zoycia Japonica Grass, Runoff Coefficient C Value, Infiltration

Abstract

Planning and designing a clean water plumbing network system is an inseparable part of building construction. Soit must be carried out simultaneously and in accordance with the planning and design stages of the building, namely by paying attention to the relationship between the construction and distribution installations in meeting clean water needs evenly. This final project research was carried out at Summarecon Mall Bandung, with the aim of knowing and analyzing the need for clean water, the distribution system, and cost estimates presented in the form of a Bill of Quantity. Meanwhile, the scope of this Final Project includes analysis of distribution pipe networks in plumbing networks, discharge and flow velocity, as well as hydraulic analysis of clean water using EPANET 2.2 software. Based on the results of analysis using Epanet 2.2 software, it was obtained that the clean water discharge of the Summarecon Mall Bandung distribution network reached 15.50 liters/second, with an average of 6000 visitors/day and a minimum clean water requirement of 223 liters/person/day. The author's change in pipe diameter size resulted in a fluid pressure value flowing in the pipe (head loss) of 673.36 m/km or better than the initial design which had a head loss of 1051.30 m/km. Keywords: Epanet 2.2, Summarecon Mall Bandung, clean water reaching, average total loss of clean water

Abstract

Irrigation is an effort to obtain and distribute water to support agricultural activities including plantations, fields and rice fields. Irrigation work is one of the criteria that describes the management of irrigation systems. Irrigation is divided into four parts, namely, Gravity Irrigation, Underground Irrigation, Sprinkle Irrigation, and Drip Irrigation. In this plan, it is located in Kab. Cirebon and Indramayu, West Java Province, in this study I will plan secondary irrigation channels at predetermined locations. In this report we will discuss, calculating the amount of water discharge, calculating the cross-sectional area of the channel, calculating the height of the channel, calculating the width of the channel, planning the height and cross-sectional area of the channel, determining the height of the trapezium shaped channel, calculating the planned flow velocity, calculating the hydraulic circumference, calculating the radius. -hydraulic radius, and calculating the slope of the channel. Keywords: Irrigation, channels, discharge

Abstract

Ventricular Fibrillation (VF) is a life-threatening heart rhythm disorder characterised by irregular and uncoordinated electrical activity of the heart that causes the heart to stop suddenly. An Electrocardiogram (ECG) is a medical test that detects heart abnormalities by measuring the electrical activity of the heart during contraction. The ECG in the VF shows very different characteristics from the normal heart rhythm, with loss of P waves and a regular QRS complex, replaced by rapid, irregular, and variable fibrillation waves of variable amplitude. A Support Vector Machine (SVM) is a type of Machine Learning that seeks the best hyperplane to separate classes. The kernel used in this study is best obtained by using the Quadratic Kernel. This study aims to detect Ventricular Fibrillation (VF) or Non-VF from ECG signals using Support Vector Machine (SVM). Preprocessing in this study: window size of ECG signals (5 seconds and 10 seconds), followed by a High Pass Filter, a Second Order Butterworth Low Pass Filter, and a Notch Filter. The characteristics used for extraction are Area Calculation (in this study, proposes using Ratio Area) and Spectral Analysis (FSMN, A1, A2, A3). Combinations of one to five of these trait extracts were trained and tested using SVM. The results obtained showed a combination of three characteristic extractions: FSMN-A1-A2 achieved the highest performance with 97% accuracy, 100% sensitivity, 94% specificity and the FSMN-A2-R characteristic extraction combination. The Area achieves 97% accuracy, 98% sensitivity, and 96% specificity. Adding trait extraction from three to four did not significantly improve performance.

Abstract

A fire hydrant is a pipe connected to a water channel, especially on a street, which is used to take water from the main channel to extinguish a fire. The hydrant pipe network system is a distribution system used to channel water from sources to fire hydrants to extinguish fires. Installing a hydrant network is an important part of the security and safety of a building, especially in commercial spaces such as shopping centers. The aim of this final assignment research is to understand the distribution system of the hydrant pipe water network at Summarecon Mall Bandung. This final project has a scope, namely the implementation method which is carried out by analyzing through EPANET software. Several SNI regulations regarding hydrants were used in this research.With this research regarding the installation of hydrant pipe networks, it is concluded that the water discharge resulting from EPANET 2.2 results can provide sufficient water supply to extinguish fires. For advice, it is hoped that routine inspections of the pipe network can be maintained in optimal condition. The safety of the Summarecon Mall Bandung shopping center can be further improved by ensuring that the installation of the hydrant pipe network remains effective and efficient. Keywords: Hydrants, Pipe Networks, EPANET 2.2, Summarecon Mall Bandung.
