Abstract

Stamplat Girang Village has quite large potential for developing micro-hydro power plants using Kaplan turbines, considering the hilly topography and the presence of the Ciparay river. The Ciparay River has quite a large water flow throughout the year. The main objective of this research is the use of the Kaplan Turbine with variations in Ciparay river water discharge. Measurements of water flow velocity and cross-section of the Ciparay river were carried out directly in low rainfall conditions and in high rainfall conditions. The average water flow of the Ciparay river is lowest at low rainfall at 0.22 m3/s and highest at high rainfall at 1.46 m3/s. With an energy height of 2 m, the effective electrical power produced is 6,592 watts in low rainfall conditions and the highest produced is 18,098 watts in high rainfall conditions. The effective electrical power obtained can be directly beneficial to various aspects of the regional government's efforts to assist the development of Stamplat Girang Village in empowerment and environmental development as well as supporting the Indonesian government's efforts to encourage the development of micro hydro energy in achieving sustainable development goals.

Abstract

Waves and currents can remove sand from the coastal areas that caused beach erosion. Beach erosion needs to be handled by building breakwater. Rubble mound breakwater is chosen to dissipate the wave energy. Rubble mound structures are widely used throughout the world; so naturally, stability tests of rubble mound structures are the most frequently conducted coastal structure model. Two-dimensional rubble mound structure physical model is carried out in a flume. The armor layer facing the seaward uses tetrapods that are placed randomly and the core layer is set to be stable by using geotube. Three different slopes of rubble mound model facing the seaward is applied, i.e., 1:1.5, 1:2, and 1:2.5, respectively. There are also four different water levels used, i.e., 38 cm, 54 cm, 63 cm, and 70 cm. The measured parameters of this study are the wave height and wave period in front of and behind the breakwater structure. The analysis that can be done is the wave absorber and transmission waves. The stability of the structure can be observed in the form of displacement armor testing on the breakwater and at toe for a wide variety of slope and water level variations.

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

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

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.
