    Abundance of litter exist in our ocean are listed among the crucial threat to the biodiversity that caused a particular concern due to the abundance, durability and persistence in the coastal environment since the area is highly productive. This research paper is to focus on coastal pollution with the objectives of identifying marine litter to relate with the land use in Kuala Perlis, Malaysia. Marine litter is collected at three points along the shoreline stretching 30 meters in length and 5 meters in width. Collected litter varied between categories and the highest amount was plastic weighing 53.15 kg/m2 followed by fabric, wood, glass, rubber and metal. Generally, there are significant relationship between land use and accumulation of marine debris. As there is a development in the area, the accumulation of marine debris increases, in contrast with the small amount of debris found in undeveloped or nonpopulated areas. The accuracy assessment obtained from Landsat 8 year 2014 and 2018 and Kappa statistics shows value range from 0.7 to 0.9 which indicate good classification performance using ERDAS Imagine 2015. Slight changes in urban development, cultivation area and forest with 1 % while for the water bodies and unclassified or cloud with 9% and 8 %.

    Leachate is known as a vigorous wastewater in terms of its organic matter and ammonia content. It is a major problem for municipal solid waste (MSW) landfill. It posed threat to surface water and groundwater. This study focusing on the removal of ammonia-nitrogen (NH3-N) by coagulation on a raw leachate sample taken from Rimba Mas municipal solid waste (MSW) landfill. The landfill leachate is tested for COD, colour and NH3N. Morphological features of calcium oxide are studied using XRF and SEM. Optimum dosage of coagulant for ammonia nitrogen removal from MSW leachate is investigated. The method used in this research was coagulant-flocculation treatment: jar test apparatus. The coagulant was conducted using hydrated lime, Ca(OH)2 with varying amount of coagulant to find the optimum dosage for ammonia nitrogen removal. A raw leachate sample taken from Rimba Mas landfill was treated with a different amount of hydrated lime (2, 4, 6, 8, 10 g/L) and 0 as a control to investigate the removal of ammonia nitrogen. The results showed that the pH of leachate (9.09) after treated with hydrated lime is increased when the dosage of hydrated lime is increased. Results showed that the best value of removal efficiency from leachate of colour, COD and NH3N were 54.70%, 56.22% and 85.25% respectively. We can conclude that as the optimum dosage increases, removal efficiency is increases.

    A study on heavy metals pollution in sediment of Kuala Perlis was done which four types of heavy metals that are identified in the coastal area. The presence of Cr, Pb, Zn and Cu are resulted from the anthropogenic activities occurs in the land use of Kuala Perlis. Samples were collected with different depth phase (subsurface, 1ft, 2ft and 3ft) at five different points (A,B,C,D and E) based on the different land use activities. The distribution concentrations of Cr, Pb, Zn and Cu in each point were analyzed by using descriptive analysis. Based on the analysis Pb gives the highest in mean concentration compared to others in all points. The relation of metals concentration and the sediment characteristics were analyzed by Pearson correlation analysis. The correlation analysis shows the positive correlation among the metals with percentage of silt and clay and negative correlation among the metals with the sediment pH. The sediment pollution assessments were investigated by using contamination indices such as Enrichment Factor (EF), Geo-accumulation Index (Igeo), Contamination Factor (CF) and Pollution Load Index (PLI). Among the four metals tested Pb gives the highest value of EF, Igeo and CF in sediments collected from each sampling points meanwhile point A gives the highest PLI value. Based on the terminologies, since the PLI value <1 so, the sediment in Kuala Perlis coastal area are considered as unpolluted sediment.
