This paper describes a numerical solution for mathematical model of the transport equation in a simple rectangular box domain. The model of street tunnel pollution distribution using two-dimension advection and three-dimension diffusion is solved numerically. Because of the nature of the problem, the model is extended to become three-dimension advection and three-dimension diffusion to study the sea-sand mining pollution distribution. This model with various advection and diffusion parameters and the boundaries conditions is also solved numerically using a finite difference (FTCS) method.

Shoreline Change Analysis

Coastal areas, being vulnerable to environmental problems, have one of the most frequent problems which are the change in the shorelines. Shoreline changes, namely abrasions, can cause problems such as land degradations or loss of land in a coastal zone. This problem occurs in many areas, one of which is Pontang Cape. This study aims to determine the distance and rate of shoreline changes that occured in the Cape and its surroundings, as well as explaining the analysis points based on similar studies that had been conducted. This research used ArcMap software and Digital Shoreline Analysis System (DSAS) toolset to determine the distance and rate of shoreline changes for 19 years (1999-2018). Based on the results, there were two shoreline segments where different phenomena of shoreline change took place, namely Banten Bay (accretion) and Pontang Cape-Lontar (abrasion). The most likely causes of changes in the shorelines are sediment runoffs from rivers that lead to bay and sediment transports that affect Banten Bay accretions, while sea sand mining and conversions of mangrove swamps into fishery ponds are factors affecting abrasions in Pontang Cape.Keywords: Abrasion, Accretion, Pontang Cape, Banten Bay, DSAS

Sea-sand mining has both advantages particularly in its destructive capabilities. The damages caused by sea-sand mining are mostly due to the unorganized mining zones. In order to minimize the negative effects of mining activities, the well-organized mining zones that have evaluated all related aspects are required. There are several aspects which are closely related to the sea-sand mining zones , one of those is hydro-oceanography aspects in its relation with the sea environments. A comprehensive analysis can be made by integrating hydrooceanography and GIS as a system of both data-organizer and software. This method is supported by using the remote sensing technology as a verification data comparison to the results of hydrooceanography analyses. The application of image analysis as a verification tool is a good method to proof the results given by the numerical simulation model. In this study, we use the Landsat images as the data analysis have indicated that the mining can be continously conducted in several locations without imposing any hazardous impacts to the adjacent environment. By considering the results above, in integrated system between the numerical model and the GIS in highly effective as a foundation to determine the mining zone where the negative effects of the oceanographic-dynamical-changes on the environment due to the mining activities can be easily recognized and predicted.

This research is an elaboration of the response of the coalition of NGOs and affected communities in rejecting the sand mining in Takalar Regency, South Sulawesi. This study aims to analyze the motives and methods of advocacy carried out by NGOs and affected communities. This study also tries to examine the factors that influence cohesiveness between those who are resistant to this extractive industry. This research uses a qualitative approach. We got data in this study through interviews, observations, and document reviews. This study found that the primary motive of the Save Coastal Alliance Against the Sea Sand Mine in Takalar expresses resistance from NGOs and affected communities on the economic and environmental effects of the extractive industry of sand mining. The advocacy method adopted includes four step strategies. The first is conducting political education for citizens; Second, build alliances with other NGOs and; Third is conducting a lawsuit and; Fourth, through non-litigation. The study also found that cohesiveness between NGOs and affected communities was   the dynamics of each group internally. This has contributed to building the context of relations between NGOs and the community.

The Government

The gap in the coastal resources utilization on the North Coast in Serang Regency has the potential to cause conflict between coastal communities dealing with local governments and sea sand mining companies. This research focuses on how the communication practices of the conflicting parties and the typology of conflict, communication interactions in conflict relations and communication strategies in conflict solutions. The research used qualitative approach which was conducted through in-depth interview with informants purposively. The results of the research showed that the dominance of natural resources was the trigger for conflict in the utilization of coastal resources on the North Coast in Serang Regency. The ineffectiveness of government and company communication in managing conflict potentials made coastal communities perceived the sea sand mining activities negatively. Coastal communities fought for their interests in various forms namely demonstrations, anarchism, social conflict between layers and human rights violations. The most active community groups were fishermen because sea sand mining had caused technical problems with fishing and decrease in income. The conflicting parties communicated with each other openly, defensively and in confrontational way. The practice of communication in resolving conflicts ran less effectively because the government and the company did not involve conflicting parties through communication to resolve the conflict. The research findings are the basis of understanding to manage potential conflicts and its escalations through appropriate communication to reach consensus to realize convergence of interests.
