Abstract

The existence of Jl. Kol. Burlian - Jl. Tanjung Api Api junction becomes very strategic because it becomes the entrance and exit of Palembang city. The intersection is access to several places such as Sultan Mahmud Badaruddin II Airport, Tanjung Api-Api Port, and the border road to Banyuasin. The position of Jl. Kol. Burlian - Jl. Tanjung Api Api junction which is very strategic cause the long queue of vehicles causing traffic jam. To overcome this the South Sumatra Provincial Government will build a fly over at Jl. Kol. Burlian - Jl. Tanjung Api Api junction. Basically the construction of this fly over as an effort to reduce the volume density of vehicles that accumulate at Jl. Kol. Burlian - Jl. Tanjung Api Api junction. The result of calculation using MKJI method calculation, the delay value before the existing fly over or signal condition is 46 seconds / smp, while the length of delay after the fly over dropped dramatically to 16 seconds / smp. Likewise with the calculation using the VISSIMprogram, the results obtained are not much different from the MKJI method, which is 45.23 seconds / smp for the condition before the fly over, and 15.18 seconds / smp for the condition after the fly over. Thus, the development of an efficient fly over in reducing the length of vehicle delays at Jl. Kol. Burlian - Jl. Tanjung Api Api junction, so it is expected to overcome the congestion that always occurs at the intersection.

Abstract

Investment evaluation on infastruchre requires careful analysis and should consider risks and uncertainties due to its unpredictable outcomes. Risk derives from our inability to see into the future, and indicates a degree of uncertainty. This paper presents the alternative approach- Sensitivity Analysis- in evaluating the most critical variables of risks which influence the investment decision on toll roads. @RISK makes it easier to see the impact of uncertain model parameters on the results and offers a powerful analysis technique for selecting between available alternatives. An advanced sensitivity analysis using Tornado Graph or Spider Graph will give the same information on the changing of the outputs.

Abstract

Serangkaian pengujian laboratorium dilakukan pada pengaruh individual dan pengaruh kombinasi dari inklusi serat sabut kelapa (SSK) yanng disebar secara acak didalam tanah yang distabilisasi dengan abu sekam padi dan kapur. Abu sekam padi dicampur dengan lempung dan pasir dengan proporsi yang berbeda. Sifat-sifat geoteknik dari abu sekam padi + tanah, dan abu sekam padi + tanah + 0,8 sampai dengan 1,2% SSK dengan waktu pemeraman yang berbeda telah diteliti melalui pengujian kuat tekan bebas, geser langsung dan triaksial. Hasil penelitian menunjukkan bahwa Pada pengujian pemadatan, untuk kadar kapur 4 dan 8% menunjukkan peningkatan kepadatan MDD dan penurunan OMC sejalan dengan lamanya waktu pemeraman.Pada pengujian geser terlihat bahwa penambahan SSK kedalam tanah – RHA tidak secara konsisten meningkatkan parameter geser tanah yaitu kohesi (c) dan sudut gesek dalam (Φ). Namun demikian secara umum penambahan SSK menigkatkan kuat geser tanah.Didalam pengujian kuat tekan bebas, penambahan SSK meningkatkan daktilitas tanah baik yang distabilisasi maupun tidak distabilisasi dengan kapur.Peningkatan kuat tekan bebas pada tanah + RHA tanpa kapur sebagai akibat dari tulangan SSK tergantung pada kuat tekan pada sampel tanpa tulangan. Penambahan SSK meningkatkan tegangan tekan pada tanah yang tidak distablisasi. Kuat tekan bebas pada tanah + RHA meningkat akibat penambahan kapur dan SSK. Hal ini tergantung pada campuran dan masa pemeraman. Peningkatan kuat tekan bebas yang disebabkan oleh gabungan kapur dan SSK relatif besar.

Abstract

Increasing demand of housing facilities has an impact on the change of land function of an area that originally forest or garden turned into a residential area. Unbalanced water surface and ground surface are the effect of the unbalanced hydrologic cycle. Volume increased and runoff, infiltration capability and groundwater decreased levels are due to hydrological cycle imbalances. That is why water management is needed in order to create a balance of water resources. One way to realize the idea is to apply rainwater harvesting methods to a residential area that is a method of collecting rainwater that is stored in a storage tank for then the water that has been collected can be reused as an alternative source of clean water. The purpose of this research is to aims the potential of rainwater that can be harvested in G-Land Padalarang Housing area, so it can be used as a source of clean water as well as efforts to maintain groundwater availability and balance of hydrological cycle. The method is by using rational method. The data used are primary data and secondary data which then analyzed based on hydrologic and hydraulics analysis. From the analysis result, by applying rainwater harvesting method in G-Land Padalarang Housing area, the volume of water that can be harvested with rainfall 2,929 mm / year and the catchment area of 66 m2 is 173,983 liter / year and can save ground water usage of 52 % of total needs.

Abstract

In big cities like Palembang, garbage is a source of waste from the community with a fairly abundant volume. Garbage can come from various modes of use like something that is no longer useful because it is damaged. In achieving the development or improvement of waste management system it is necessary to know the characteristics of waste generating sources include waste generation. The purpose of this study is to calculate the amount of waste generated by the housing and non-housing sector and to analyze the relationship between waste generation between housing types with correlation analysis. This research method refers to SNI 19-3964-1994 with 100 samples of housing waste and 120 samples of non housing waste that used purposive sampling. The Result of this research : in waste generation housing type of organic waste is generated by non-permanent housing, while the type of non-organic waste is generated by the type of luxury permanent housing. For non-housing waste generation waste type of organic waste is more generated by the market sector while for non-organic waste generated by the sector of shops. From the result of the weight correlation test of waste generation, it is found that non permanent and permanent waste generation has strong correlation to permanent housing waste. From the results of Anova One Way test of weight of waste generation obtained that the weight value of waste generation for semi-permanent housing did not experience a significant difference to other types of housing.

Abstract

Landslide is one of the most common problems in improving road structures. One of the landslide cases occurred in the area of Kikim Besar, Lahat District precisely at Km.256. To obtain an optimal solution of the problem requires proper analysis in the reinforcement of the slope. In this study used an alternative slope reinforcement by using sheet pile or geogrid reinforcement. The purpose of this research is to know the condition of natural slope stability at that location and the effect of stability slope change with retrofitting structure using sheet pile or geogrid. This research uses modeling with Plaxis 2D program. Modeling was made to obtain the safety factor values on the natural slopes on the slopes 1-1, 2-2, and 3-3 pieces, comparing the safety factor of each slope before and after the reinforcement, and comparing the safety factor of each slope after reinforcement using geogrid type UX 1700 and sheet pile type W325 A 1000. From the research results obtained that the strengthening of geogrid and sheet pile can increase the value of slope safety factor. The sheet pile modeling has the greatest safety factor value for each slope of 1.794 for slopes 2-2 and 1,532 for slopes 3-3 compared with geogrid reinforcement that produces a safety factor value of 1,325 for slopes 2-2 and 1,343 for slopes 3-3 pieces.

Abstract

Road pavement is structural section of traffic lane which has central position in road body. Road pavement age is related to surface durability which can be influenced by oil spill accidently especially for gasoline, diesel oil and lubricant brought by vehicle, so it may decrease road and service age. Because of that, this research will detect the fact of influences by spilling oil out to Lataston-WC. In planning pavement layer model, mix and material testing must be done. There were 15 normal samples in this research with KAR (Pb) to define KAO value and 24 samples with KAO value to be soaked with fuel and lubricant in duration vary from 1, 3 and 5 minutes. Marshall test was done by 1 hour later. Then, it was analyzed and concluded. The result showed that asphalt optimum capacity reached 6,7% which then samples be made and soaked in fuel and lubricant. For normal mix samples, stability value reached 1951,87 kg and soaked samples with 5 minutes duration reached 511,56 kg. It can be concluded that duration of soaking also influences in decreasing stability value.
