Abstract

Abstract. Wotgali Village is a slum area. The aim of the current research is to find out the performance of slum base infrastructure using Lakip (Government Agency Accountability Report) of KOTAKU (City without Slums) Program. The first step was performed by identifying the initial settlement (base line), then some treatments on the facilities and infrastructure (finish line), performance evaluation stages of the preparation, planning, implementation, and sustainability stages. The research used qualitative and quantitative approach. Qualitative measurement began with a numerical assessment of the results on the level of regional slum. In addition, quantitative data used the Lakip simulation using results of the KOTAKU program stage performance. Results of the initial condition reach value of 32%. It is categorized as slight slums with an average sectoral slum of 36.68%. Basic infrastructure development which has final technical reached 24% and is included in slight slum with an average sectoral of 27.50%. The performance of LAKIP Kotaku was in preparation phase 90.46% (very good performance), planning stage was 89.93% (very good performance), implementation stage was 90.25% (very good performance), sustainability stage was 85.21% (better performance). Thus, the achievement of KOTAKU program is 85.19% with a range of value of 80-90. The value is included as better performance result. Results of the analysis can be concluded that level of slum can be reduced to 19% (not slum) by creating some improvements to basic facilities and infrastructure.

Abstract

Abstract. Darma Reservoir functions as a reservoir for irrigation, fisheries, and recreational and sports facilities. Currently, it only functions for irrigation and fish farming by floating net ponds. The development of floating net frameworks was so rapid that it conflicted with reservoir management. This study aims to determine the density of the floating net framework of the sedimentation conditions of the Darma Reservoir and to determine the development of the sedimentation rate of the Darma Reservoir in relation to the service life of the reservoir characterized by reduced dead storage. The first step was carried out by surveying the presence of the number of floating net cages, the distribution of the feed, the percentage of feed demand, the carrying capacity of the reservoir, then a topographic survey of the depth of the Darma reservoir to determine the capacity, rate and volume of sediment deposits. This study used quantitative approach, it began with distributing questionnaire forms and measuring the depth of the reservoir. The current condition of floating net cages is 4916 occupying 5.819% of the inundation area of 312.15 ha with an elevation of 712.50 m, while floating net cages are allowed according to the carrying capacity of Darma Reservoir waters amounting to 1,021. tons / harvest while the spawning pond is 3.483 tons/harvest. The volume of normal active storage for elevation 712.50 in 2020 is 28.086 million m3, while the volume of sediment deposits is 9.262 million m3 32.98%, the average sediment rate in the reservoir from 1988 to 2020 is 0.2894 million m3/year, while the sediment rate in catchment area Dam Dharma with an area of 23.5 km2 of 71.873 mm/year. Sedimentation in the Darma Reservoir has exceeded the limit of the base elevation of the reservoir, the elevation of the dead reservoir and the lowest elevation, but the reservoir is still functional.

Abstract

The development of glue-laminated (glulam) lumber beam gives many good results. Meranti (Shorea SP) is one of the construction lumber that can be used as glulam to optimize its use. The limitation of the glulam lumber beam is the limited length of the lumber, so it must be joined to get a certain length. The lumber available in the market on average has a limited size and cross-sectional length. The larger the cross-sectional size and length of the lumber make the higher the price. Used lumber and residual lumber also have many weaknesses, such as the length of suitable lumber is too short, lumber defects, and lumber damages. Further research needs to be done to optimize the use of new, used, and residual meranti lumber through the use of lumber pieces as a glulam lumber beam maker. Standard specimen and test based on ASTM D-198. Glulam lumber beam is made from pieces of meranti lumber planks of certain length which are arranged into lamina beam with the size of 5.5x9.5x150 cm3. Variations in the length of the pieces of meranti lumber planks for making glulam lumber beam, among others, 40 cm, 50 cm, 60 cm, 50 cm with full length lowest layer and 150 cm (full length). The adhesive used is polyurethane glue. The span between supports is 130 cm. The beam is tested for center point loading. The analysis results show that the joints on the outermost layer that receive tensile stress of the glulam lumber beam can cause weakening in the beam because the tensile strength of the adhesive is weaker than the tensile strength of lumber. Failure at the tensile joint of the outer layer of the beam can trigger a shear failure mode. Design of joints should not be placed on layers that are subject to tensile stresses so as not to trigger shear failure modes so that the strength of the glulam lumber beam can be optimal.

Abstract

Abstract Kali Lamong River with a trapezoidal channel shape has a bottom width of about 30 m, a top width of 40 m and a depth of 3.5 m. In one of the river segments, the basis is in the form of a fixed bed and it is assumed that there is no sediment transport in this section. On the downstream side after the fixed bed section, the river segment is a mobile bed with river bed material that has an average grain diameter of 1.5 mm, a relative mass density of 2.6, and porosity of 0.3. Flowrate with Q50 is 1000.00 m3/sec with a maximum flow speed of 15 m/sec. Riverbed degradation will occur initially at the upstream point in the fixed and mobile beds. Depth of riverbed degradation calculated by the Parabolic model of 80.00 cm / year based on the solution of the equation.

Abstract

Abstract. The Sampean Baru watershed is categorized as an area with a very high level of vulnerability to drought. The purpose of this study was to assess the hydrological drought in the Sampean Baru watershed. NCEP / NCAR Reanalysis climate change data is used to obtain synthetic rainfall models of the past. This climate change data has crude resolution and is global in scale. The NCEP / NCAR Reanalysis data was processed through a downscaling process to obtain local scale climate data in the form of past synthetic rains. Artificial Neural Network (ANN) is one of the downscaling models used in this study. The ANN downscaling output was processed through discharge modeling using SWAT. Hydrological drought assessment used the Standardized Precipitation Index (SRI) method. The SRI calculation was based on the accumulated discharge over a period of time. The results indicated that the ANN downscaling process can bridge global scale climate data to local scale climate data. SWAT modeling gave excellent results. SRI-6 can describe past droughts. It can be seen from the compatibility between the results of the drought assessment and the drought data belonging to the relevant authorities.

Abstract

Abstract: Various kinds of buildings in civil engineering require careful planning. For example, in the planning of a water building needed a method to calculate the design flood discharge before starting to plan the dimensions of the building to meet the effectiveness of the water structure. Design flood discharge can be determined using several hydrograph methods that have been used in water building planning in Indonesia. One of the popular hydrograph method used is the Nakayasu Synthetic Unit Hydrograph method. In this case, the design flood discharge is located in the Garang watershed, precisely in Semarang City, province of Central Java, using rainfall data for the past 16 years. Hydrological analysis is carried out first before determining the design flood discharge with a return period of 2, 5, 10, 25, and 50 years. The results of the design flood discharge using Nakayasu method respectively were 305,522 m3/s, 390,742 m3/s, 447,783 m3/s, 520,560 m3/s, and 574,912 m3/s.

Abstract

Abstract. As part of urban public space, playgrounds are a children's play space that can improve children's sensory, communication, and physical abilities. Playgrounds must be able to create comfort and education for children to engage with nature. One of the approaches to achieve is by the vegetated setting. Tembalang is a sub-district in Semarang, with children dominating 44% of the total population. Therefore, the playground's effectiveness in Tembalang was assessed based on comfort nature and connection with nature. Nine playgrounds are the object of this research. This study is aimed to determine the effectiveness level of the playground in Tembalang using the vegetated-setting approach. The research used a quantitative approach with Guttman-Scale scoring. This study's output assesses the level of effectiveness of the vegetated-setting playground through two aspects. The first aspect, comfort nature, which included in the effective level (71%) in the form of vegetation, protects children from heat and rain while playing, vegetation that provides shelter when children relax or gather under trees, vegetation can cause cold air and the condition of the grass field. It is comfortable to use and is not slippery. In comparison, the second aspect, the connection with nature, is included in the effective level (50%) in the form of plucked vegetation such as fruit or flowers, vegetation that can climb to train the child physically, vegetation that can bring animals to live in, such as birds or butterflies, and grass fields that children can use for running and physical activity.

Abstract

Abstract Fire is a disaster that must be avoided in various ways, one of them is by using a fire extinguishing system to prevent fire disaster. This study used the Semarang City Health Office (DKK) Building as a sample. The purposes of this research were; (1) to find out whether the application of the fire protection system at DKK Building has met the regulations and (2) to determine whether the water distribution in the fire protection system in the Semarang DKK Building is functioning properly as needed. Data collection methods in this study consisted of observation and literature study. The observation was used to find research data in the form of planning drawings on the building protection system and the literature study was carried out to obtain data in the form of standard tool specifications and rules for using tools in the protection system. This study also used an analysis method based on an application program called Epanet 2.0. The Epanet program was used to simulate a hydraulic model according to the fire protection system at DKK Building. The results of the analysis using the Epanet 2.0 show that the sprinkler system has met the needs based on the amount of water supply discharge and based on the required pressure. The underground tank volume of 150 m3 has met the requirements based on SNI 03-3989-2000. The pressure value for all sprinklers has met the requirements of SNI 03-3989-2000 with the smallest pressure value is 2.5 kgf / cm2. The sprinkler system does not meet the water distribution value set in NFPA 13 with a maximum distribution time of 50 seconds while the analysis results show that the distribution time is 205 seconds. The pressure value at all points of the fire hydrant system meets the SNI 03-1745-2000 rules with a maximum value not exceeding 24.1 bars. The pressure value at the farthest hydrant box hose connection does not meet the SNI 03-1745-2000 rules with the pressure value at the farthest hydrant box is 4.6 bars, where is the minimum pressure is 6.9 bars.
