Abstract

The objective of this study is to provide an alternative design of sediment problems in Kuala Raja Port that causes disadvantages for the local fishermen due to ineffective port utilization. The primary surveys conducted in this study are topographic survey, bathymetry survey, current survey and geological survey. The wind data is obtained from the Malikul Saleh Meteorological Station. Based on the tidal survey, the water surface during the tide water is 1,56 m above  0.00 m LWS. The current data shows that the flow rate is low, which is less than 1.5 m/sec whereas not interfere ships’ movement, because the standard size of ships allowed crossing the shipping lanes is planned less than 50 GT. Based on the correction using SPM nomogram acquired high waves 3.50 m with wind speed > 20 knots and the North largest fetch  490.04 miles. Sediment transport on shore of Kuala Raja beach is  46,934.59 m3/year moves from West to East. The hand bore data on the location of the planned jetty obtained SG = 2,648, Wc = 25.66, gd = 1,549, f = 31.00, c = 0.03. Therefore, the determination of the layout of jetty at Kuala Raja Port is considering the direction of sediment transport, the wave height that occurs, the field data attained and the economic feasibility. Sediment management at the Kuala Raja Port can be done within 2 (two) ways: firstly by increasing the length of the jetty on the left and the right side and, secondly by dredging the navigation channel. The length of the jetty that is needed to expand on the left side is 284 meters long and 127.65 meters long on the right side, in order to avoid the addition of sedimentation volume. The jetty’s slope is planned 1: 2 outside the channel and 1: 1 inside the navigation channel. The dredging volume at the port entrance is approximately 39,811.60 m3.

Abstract

Glass waste is harmful if it is disposed of and mixed with other waste. A special disposal site is needed to avoid injuring the hands and feet of the garbage collectors, especially at the Final Disposal Site (TPA). Glass waste highly consists of silica (SiO2), which is needed in cement. Glass waste is crushed by a mechanical method using a crusher, creating glass powder with an average size of 54 µm. Cement is mixed with glass powder in a ratio of 4:1. Water cement factor (FAS) is used at 0.3. The partners in this community service activity are primary school-age children in Ateuk Lam Ura Village, Simpang Tiga District, and Aceh Besar District. The success of the resulting product is indicated by its compressive strength, the hardening of cement and glass powder, and the product's visual appearance without any visible pores. The product has good strength and looks neat with a solid surface. The compressive strength of the product obtained is 3.21. Partners are interested and can apply glass waste to flower pots properly.
