People have become aware that maintenance of symbiotic relations between people and their surrounding environment is important not only for people’s happiness but also for their own existence on the earth system. Facing up to reality, however, there have arisen matters of regret caused by the human lives and activities. One of big problems we have to consider is scatter of waste and debris on natural beaches, especially in the coastal area near the dense populated area. We have to remember that the scatter is the results of human activities mainly on the coastal land area. The problem had become serious on a small island located near the mouth of Osaka Bay, where rubbishes such as tins, bottles and plastic bottles, bags and sheets have been piled and remained on the beach for more than half a century. People living in a small community, who were worrying about the decline of the ecosystem of the small island, started the activity of beach cleaning more than ten years ago. Since then, the quality of the ecosystem on the island has been maintained in a permissible condition. They also started the field researches on the fauna and flora in and around the island to make an inventory of fauna and flora. Their activities were appreciated and they were honored with testimonials commending their contribution on the maintenance of symbiosis. In the present paper, people’s activities are introduced with the importance of promoting the symbiosis with ecosystem in surrounding natural environments.

Coastal water is vulnerable to anthropogenic substances such as human activities by product in coastal land and  upper land area. Semarang coastal area is one of areas which has progressive development in northern coastal of Java Island.  The aim of this study was to evaluate ocean health status based on heavy metal contain and benthic foraminiferal characteristics as the bioindicator.  Sampling and laboratory activities were carried out in August 2010. Sampling stations were located on the estuaries of Western Canal Flood, Tanjung Mas Port and  Eastern Canal Flood.  The result showed that Tanjung Mas pool port had the highest Pb, Zn,and Total Organic Compounds (TOC) concentrations. The average of abnormal test of benthic foraminiferal (Ammonia beccarii) were also higher in Tanjung Mas port than in eastern and western canal flood. Keywords: assessment, coastal water, Semarang.

Management of coastal areas on the east coast of Surabaya (Pamurbaya) is very important because this region is largely a conservation area which serves to maintain the balance of the ecosystem of Surabaya. This study aimed to analyze changes in the coastal land and create a dynamic model of coastal land area changes in Pamurbaya. The method used is the field survey, the linear regression method and dynamic modeling. Dynamic modeling using the software Stella 4.0. The results showed that the changing of used land can be explained by the dynamic model described by a linear regression model. The result is useful to predict the pamurbaya condition for next few years and useful as inputs to city government in managing coastal areas of Pamurbaya.

The development of shallot farming in Adipala Sub-district starting in 2018 faced several problems, namely most farmers still had low experience of shallot farming, the type of land that was less fertile, shallot seeds from Brebes which were not specific to coastal land. This research aimed to analyze 1) revenue, cost, income, and R/C, 2) the level of production risk, 3) factors influencing production, 4) factors influencing production risk. The research object was farmers who carried out shallot farming during the growing season from November 2019 to January 2020 in Adipala Village, Bunton Village, and Karanganyar Village. The sampling method was saturated sampling. Data analysis consisted of analysis of revenue, cost, income, R/C, coefficient of variation, and Just & Pope production risk function regression. The results showed that the shallot farming in Adipala Sub-district was profitable, namely per farm it had revenue Rp10,834,600.00, cost Rp9,999,943.61, income Rp834,656.39, and R/C 1.06. The production risk level was high at 85.49%. Factors that had been shown to significantly influence production were land area, seedlings, labor, agricultural lime, petroganik, manure, TSP, ZA, KCl, NPK, herbicides, and fungicides. Meanwhile, factors that had been shown to significantly influence production risk were TSP, NPK, and fungicides.
