Abstract

Strength based design is commonly used in the design of resisting earthquake building. It is analyzed by linear elastic method so that it can’t describe the seismic behaviour of the structures. For that reason, the design of structure needs to consider performance based design. Irregularity of structure play important role for the results of Structure Performance. This paper uses five models of 20 storey reinforced concrete building with same height(76 m) and areas(750m2) with different plan configurations: rectangular, T, L, U, and H-shaped. Non linear time history method is used  to investigate the seismic behaviour of the structures, using finite model with ETABS2016. Dimension of structures are column (600 x1000 mm), shear wall (400mm), couple-beam (400x900 mm), slab (140mm). Recorded accelorogram used in this paper are Altadena, Array, Corralit, LACC, and Yermo because it has almost same earthquake mechanism, magnitude, and epicentrum distance, so that they are used as an artificial accelorogram that is synthesized using Wavelet Function according to SNI 1726-2012.Result shows that the story drift and plastic hinges for collapse prevention (CP) are: rectangular (story drift is 0.59% and amount of CP hinges are 8), H-shaped (1.58%/23), L-shaped (2.41%/30), U-shaped (4.59%/35), T-shaped (5.8%/58).

Abstract

Water is the most basic requirement that is necessary for a good life on land, sea or air. Water in the face of this earth are not directly derived from the rain. All living things need water to survive. Water management should be done as quickly as possible so that its availability is maintained. Along with the development of the times and increasing daily population in Indonesia, the demand for water continues to increase. Indonesia has a tropical climate with two seasons, the dry season and the rainy season. During the dry season of drought, while in the rainy season floods. One reason is the change in land use that result in water catchment areas disappear and be replaced by buildings some hydrological model was developed to determine the water balance, such as infiltration models. Infiltration models are used to determine how much of the surface runoff or inundation (ponding) which can be infiltrated. The purpose of this study is to analyze the model's ability to absorb water in a simple infiltration runoff, infiltration simple models to analyze the influence of the flow between, to analyze the efficiency of a simple infiltration models to infiltration, and a simple model to analyze the influence of water turbidity in a state of unsaturated and saturated water. The results showed that the soil with plants media can reduce runoff and improve water quality due to rain than vacant land. Discharge runoff on bare ground while unsaturated and saturated water of 0.136 liters/sec and 0.134 liters/sec, while on the ground with the current crop of media unsaturated and saturated water at 0.1330 liters/sec and 0.1300 liters/sec. The content of the suspension on a vacant lot when unsaturated and saturated water is 6.88; 4.20; 3.94 mg/l and 2.13; 1.66; 1.11 mg/l, while in the soil with the current crop of media was saturated and saturated water is 4.40; 4.22; 2.35 mg/l and 0.92; 0.83; 0.63 mg/l.

Abstract

In this research, we attempt to determine preference of rheotaxis and estimated weight values in laboratory experiments using adult and juvenile ayu (Plecoglossus altivelis altivelis). We conducted paired comparisons of ayu distribution between the upper and lower sections of a test watercourse using several velocity conditions (10, 30, and 40 cm/s for juveniles; 20, 30, 50, 70, and 90 cm/s for adults). In upper watercourse sections, juvenile ayu preferred velocities of 30 cm/s and 40 cm/s, and adults preferred a velocity of 50 cm/s. Even when a highly preferred illumination condition of 4000 lux was present in the lower section, fish maintained a higher distribution in the upper section. We design a procedure to calculate rheotaxis preference and built it into our fish behavior simulation model on geographic information system (GIS) software. The model successfully predicted natural migration behavior of fish.

Abstract

Many studies have shown that land use changes in watersheds such as forests that convert to settlements, industrial and estates, have an impact on flooding. So it is important to know the correlation between the various land use changes to the discharge within a watershed. This study is a preliminary study in an attempt to assess the correlation between land cover index and peak discharge, with case studies in the Beringin River Basin.The peak discharge with the return period of 2, 5, 10, 20, 50 and 100 years are computed with HEC-HMS software, developed by Hydrologic Engineering Centre (HEC) and US Army Corps of Engineers which computes the runoff discharge from the precipitation. As for land covered index (LCI), it is defined as the sum of the land-use index (LUI). The result of the case study shows the strong correlation between the land covered index with the the runoff discharge with such relation : Q100 = -22.42LCI2 + 214.30LCI - 10.62, Q50 = -18.33LCI2 + 181.87LCI - 20.19, Q20 = -14.30LCI2 + 145.27LCI - 15.61, Q10 = -11.36LCI2 + 118.41LCI - 12.29, Q5 = -8.42LCI2 + 91.27LCI - 8.9 and Q2 = -4.44LCI2 + 53.54LCI - 4.5.

Abstract

The competition strictness in the economic field needed the exact strategy to maximising the available potential. As the  island area that was surrounded by ocean, the Mukomuko Regency in Bengkulu, had the big potential to be developed especially in the export import activity and the sea transportation. There were 4 port kinds that will be developed in the Mukomuko Regency those  are the crossing port, the sea port, the trade port and the fish port. The determination of priority in the port kind and it location that developed immediately must be carried out, so  the port that was built could be used maximally. The data collection was carried out with observation and the interview. The variables that was used as the determination criterion of  priority in the port development was marine aspect,  fisheries aspect,  transport aspect, layout aspect and environment aspect. The research results showed that location in Mukomuko more appropriate for the crossing port, the location in Bantal was more appropriate for the fish port, the location in the Kumbang Badak appropriate for the sea port and the location in the Kuala Tramang more appropriate for the trade port especially agricultural produce. Based on result of Analytical Hierarchy Process (AHP),  the development of  sea port in  Kumbang Badak became the main priority to built immediately.
