Abstract

As one of the strategic port of Tanjung Emas Port in Semarang Indonesia can not be separated from a variety of problems. From the analysis, in 2012 the capacity of the Port of Tanjung gold almost exceeded the maximum limit. In the container dock and public piers ideal has exceeded its ideal capacity. Protection of the pier from the brunt of a wave also not enough. Wave height reaches 71 cm in the dock being critical limit allowed is 50 cm. Another issue that still has not been able to overcome the level of land subsidence in the port area is very rapid at 14, 63 cm / year, so many areas in  lower elevation of the sea level . Because of that, rob at high tide occurs in some port areas. To overcome these shortcomings and to develop. From the analysis planned, towards the development of the Port of Tanjung Emas include lengthening container dock along 300 mx 25 m, the expansion of container yard area of 15 hectares, the elongation of breakwater along 150 m and the polder planning system as a protection against tidal.

Abstract

Tukuman Weir is a weir of Dengkeng Cawas River, Klaten Regency, Central Java. This weir got a severe damage due to the excessive discharge in December 1989. This caused the people around the weir irrigated their field by free intake. The problems discussed in this paper are 1) the damage of the weir overflow, and 2) the damage of the tail water. The aim of the research is to maximize the flow of water into the irrigation network that the need of irrigation water can be met properly to increase the income of farmers each year. This research uses the latest data which then is processed by using hydrological analysis as the basic of the next planning. Watershed (DAS) of Dengkeng River is 101, 157 km2 in large, with three rain stations: Gantiwarno, Kemudo and Ngelo. The calculation of flood discharge plan uses several methods. The chosen discharge is the result of the calculation using HSS Gama I method with return period of 100 years, then continued with Qdesign=110 m3/sec. The large of the irrigation area of Tukuman weir is 150 hectares, with 0.22 m3/sec water need. From the result of the balance sheet analysis, the need of water irrigation is fulfilled, even it is a surplus. The rehabilitation concept is combining the fixed and barrage, but keeping the elevation of the old weir overflow. The redesign of the weir dimension with the fixed weir, the elevation height of the overflow is +102.02 m.dpl, rounded overflow with effective width of 7.75 m. While for the motion overflow, the overflow elevation is +99.7 m.dpl as planned, with 5 doors and effective width of each is 2.5 m. the length of the floor to the weir face is 10.5 m as planned, and the tail water of USBR type III is chosen. The cost of the weir rehabilitation is Rp. 3,241,000,000 with time estimation is 20 weeks. Based on the calculation, it is obtained that there is surplus on the water need that might be considered using it for other needs, for instance, enlarging the irrigation area or fulfilling drinking water needs.

Abstract

The problem that often happen nowadays is flood in rain season and drought in dry season. The other problem is land degradation for infiltrating water caused by environment changes which is land development effect. One of problem solving and ground water conservation effort at Diponegoro University Campus Area is to build drainage with infiltration well. This drainage with infiltration well is expected to reduce run off water caused by development at Undip campus area. This designing process does the hidrology analysis with rainfall data for 15 years at Sta. Gunungpati, Sta. Banyumeneng, and Sta. Pucanggading. The hidrology analysis for this design use normal probability distribution and rational method with rain repeat period 2 year. This hidrology analysis results are post-development flow (Qpascapembangunan) 4,633 m3/s and pre-development flow (Qprapembangunan) 2,357 m3/s so it can be know that development caused increasing flow (∆Q) 2,277 m3/s. The analysis result is used to design the drainage channel and infiltration well. In this design, the drainage channel at Undip campus is still good to use so it is just need to build infiltration well. Infiltration well dimension is 0,5 m diameter, 1,2 m depth and 3 m length between infiltration wells. There is water catchment box and infiltration well’s cover on the top each infiltration well. Water catchment box dimension is 0,8 m length, 0,8 m width and 0,1 m height, while infiltration well’s cover dimension is 0,6 m diameter and 5 cm width. The existencies of drainage with infiltration well can absorb water about 11,885 % from run off flow caused by development (the differential flow between pre-development and post-development) , that calculated with method for Research Effect of Hydrology and Hydraulic Caused by Infiltration Well Combination at Drainage System with infiltration well condition. To determine the effectiveness of the water absorption from infiltration well, this study is calculated water absorption for a year in 2011. This calculation is using two intensity approaching methods, namely: Mononobe Method and Alternating Block Method (ABM). From these calculations predicted drainage with infiltration well that can absorb water 12.051% - 43.660% of the discharge rain, so the volume of absorbed water reach 600,000 m3.

Abstract

Flood is one of the disaster which often happened in Semarang city. Many negative impact arising from flood disaster, such as loss of victim or material. One of the handling solution is  developed flood shelter. Some region of Semarang cityhave own flood shelter, so in this case we need to identify of elegibility and improvement. Identification location of flood shelter are in Beringin Watershed Semarang which consists of 6 Kelurahan, namely Kelurahan Wates, Kelurahan Wonosari, Kelurahan Mangunharjo, Kelurahan Mangkang Wetan, Kelurahan Gondorio, and Kelurahan Beringin. Data obtained from the field survey,with existing data of flood shelter that has been there. Sources of criteria for  flood shelter location are sphere project handbook, 2011, Health Minister’s decision on the minimum sandart of health problems caused by disaster prevention and handling of refugees, and egulations of BPBD. Some regions like Sub-District of Wonosari require a building in the form of House Podium and emergency doorstep. Because the location have bank- bank resulting the pursuing of evacuating and handling. Besides, some shelter pitched a tent of the size according to requirement to accomodate lacking of room for refugee in shelter. But, people arround the riverbanks should keep the environment clean and not littering, so can decrease the impact of flood.

Abstract

As the construction rapidly growing in Indonesia, it causes the land decreasing that can be used to absorb water. This phenomenon will cause an often flood in rainy season and drought in dry season. On the other side, the degradation of land infiltrations as the effect of the changing  of environment. Before the development of the area, the studied area contributes of flow by 0,167 m3/s and volume of run-off equal to 601,2 m3. After theconstruction of Tembalang Pesona Asri regency , the post-development peak of flow and run-off volume increase to 0,573 m3/s and 2061,8 m3. Eco-drainage is defined as efforts to manage the excess of rainfall water by infiltrating into the ground as much as possible or flowing naturally into the river without exceeding the capacity of the river before. Eco-drainage facilities that offeredin this final task included infiltration wells,  and bioretention cell. To restore the flow and volume of runoff around the pre-construction condition, the minimum eco-drainage facilities need 177 units of infiltration wellswith diameter size dimension  of 1,5m depth of 3m, 1300 m2 of bioretention cell which 560 m2 located in Blok R and 740 m2 in Blok A. The construction of this Eco-drainage facility in the Tembalang Pesona Asri regency area can decrease runoff of 1220,419 m3 or 83,5 % from the runoff water cause by the regency construction. This construction of the Eco-drainage facility need approximately 3 months of time with  total cost  Rp. 1.209.126.133,- (one billion two hundred and nine million one hundred twenty-six thousand one hundred and thirty-three rupias). The houses total in Tembalang Pesona Asri Regency are 287 units, so each house’s contribution is equal to Rp. 4.212.983,- (four million two hundred twelve thousand nine hundred eighty three.
