Abstract

Breaking wave near beaches is the main force to generate longshore currents, which moved the sediment at surrounding area. Due to its negative outcome, which are erosion and sedimentation, the need of longshore sediment transport analysis become very important. One of the tools for solving that problem is by using coastal protection structure such as permeable groin. Permeable groin may reduce the rate of longshore sediment transport respectively by changing the level of permeability of the groin itself. The objective of this research was to obtain analytical results of the longshore sediment transport reduction analysis by using permeable groins at Tanjung Bayang Beach of South Sulawesi. Reduction of sediment transport along the beach was analyzed by calculating reduction coefficient, which is the ratio between the longshore current before and after hitting the permeable groins. The result showed that with 40% of permeability, the groin can reduced longshore sediment transport at Tanjung Bayang Beach for almost 50%; from 341.37x103 m3/year to 170.68x103 m3/year.

Abstract

The golden age of the oil business in Indonesia is over and now petroleum is even a burden. As oil producing countries prepare themselves to start the second phase of the golden era of oil, Indonesia is heading towards an era of energy crisis (Indirasardjana, 2014). Renewable energy is needed as an alternative to meet the community's fuel needs. Beach sand is one material that can be used to help the biomass gasification process. Small particles of sand are filled into a container and gas is flowed from below and suppresses the flow of each particle which is useful for the biomass decomposition process. When using beach sand, we can also utilize heat energy optimally in coastal areas to make gasification reactions easier. This study aims to examine the groups contained in the TMS (Tetramethylsilan) spectrum of the beach sand filtrate fluid by paying attention to the CH3 compounds which are arranged in TMS. FTIR test results show that the beach sand filtrate fluid gives an illustration that from wavelengths of 3000 to 3500 the sharpness of the amount of nitrogen and hydrogen in the sand beach filtrate liquid solution can be used as ammonia gas (a fuel). Nitrogen and Hydrogan when bound with Hydroxide will form ammonium hydroxide which can function as a fuel (heating).
