Abstract

Reported, 65% of Java island population are living in coastal area where one of the most affected areas on climate change. Disaster related to hydrological cycles such as flooding caused by tidal is the most frequent happen in the low area zone as well as Semarang city in Central Java province. Many process impacted tidal flood: land subsidence, sea level rise, and coastal land use change as a consequences of population pressure. It will getting worse when heavy rainfall is occur. Predicted, 2672, 2 Ha of coastal area at Semarang city will inundate caused by 16 cm sea level rise due to global warming impact. By this fact, coastal community is the most vulnerable group due to the flood. This paper is a preliminary study to simulate the interaction of humancoastal environment to response, adapt and mitigate the tidal flood through agent-based modelling (ABM) within spatial concept. ABM frameworks have been portrayed to function well in a socioenvironment context, modelling efforts for coupled human-coastal environment system that described as a process-based design framework. In this research, human actions are interpreted as an aggregate social response to stimuli from the physical system with both aspects being explicitly modelled at the scale of emergence of the hydrological phenomenon in coastal areas. The natural (coastal-hydrology) system is set, in modelling terms, through physical (tidal, land subsidence, land use change) models; the response of human units (settlements, fisherman, industry communities etc.) is then studied as a reactive mechanism to physical model output, such as tidal flood. In the other word, ABM is an empirical methods for building agent decision models in spatial planning. Keywords: agent-based model, coastal environment, human interaction, spatial planning.

Abstract

In flexible pavement, base course is the layer immediately under the wearing surface layer. Because the base course lies close under the pavement surface, it is subject to severe loading. It follows the materials in a base course must be of extremely high quality. To get high quality of base course, research on treated base course with Buton Natural Rock Asphalt (BNRA) have been conducted. Amount of 10, 15, 20, 25, 30, and 35% BNRA by weight of base course aggregate are mixed in the base course aggregate. California Bearing Rasio (CBR) and direct shear test are performed to the mixed of BNRA-base course and also to the original base course to konw how far the influence of BNRA to improve the strength or quality of the base course. The test results show that with BNRA 25% the CBR value can increase from 52.30% to 98%, and cohesion change from 0.127 for original become 0.199 for base course treated BNRA, as well as angle of internal friction (φ) increase from 210 to 430. It can be concluded that BNRA is suitable to use as material for treated base. Keywords: Buton-Natural Rock Asphalt, Treated, Base Course, Improve, Strength.

Abstract

Soil is base and the most widely material used for civil engineering and structural engineering construction. However, not all kind of soils can be used for the construction. For a soil having low a shear strength such as a soft soil, it needs to stabilize. Stabilization methods that commonly used are by compaction or chemical stabilization. With the objective to study the shear strength of clay soil, this research performed an experimental study by adding variation of limestone powder to clay soil. The clay sample is from Nganjuk city, East Java that is classified as a montmorillonite clay with Gs number is 2,698; liquid limit 62,6 %; plasticity index 19,07% , and the qu number is 1 Kg/cm2. The percentages of the limestone powder were in 5%,10%,15%,and 20%. The pure clay and modified clay were tested using Unconfined Compression Test (UCT). The result showed that with the addition of 20% limestone powder may decrease the Gs number to be 2,351; liquid limit 54,2%; and plasticity index 7,81 %; however the qu number increased with the addition 5-15% limestone powder but it decreased with 20%. Keywords: clay soil, soil stabilization, limestone, shear strength, unconfined compression test
