Heavy metals in waters are a threat to living things both biota that are in these waters, as well as on plants and humans that depend on these water sources. Water quality improvement can be done by utilizing local gravestone (Pilsbryoconcha exilis) as a natural filter. In this study consisted of four treatments and three replications. The amount of gravestone weights of 200 grams, 300 grams and 400 grams acts as a treatment that will later be seen its effect on water containing arsenic metal. The results of this study indicate that local gravestone can reduce arsenic levels in waters with a treatment weight of 400 grams showed the best results with the final result arsenic level of 0.0101 ppm and the highest daily growth rate is 200 grams of weight treatment with a market value of 4.40%.

Merger is the merging of two or more companies so that the company becomes better and creates new dynamics. Besides that, it creates efficiency and increases market share, expands the business that is run and has stronger competitiveness. This is the goal of the merger of 3 state-owned Islamic banks including BRI Syariah, BNI Syariah and Bank Mandiri Syariah to become Bank Syariah Indonesia (BSI). Bank mergers are deemed necessary in order to create a better bank which in the end can have a significant and positive impact on a banking system that is healthy, efficient, resilient and able to compete in the increasingly tight and competitive global economy and free market. This series of mergers clearly reduced the number of banks. This raises important issues, including whether the smaller number of banks has reduced or even increased the concentration of the banking industry. In addition, it is also interesting to analyze the impact of the merger on the level of banking competition. This study aims to assess the impact of Islamic banking merger policies on market conditions. After the merger, will the market become more competitive or will it become more concentrated? The research method used is literature study. The structure variable is seen from the total assets and market share, the conduct variable is seen through the merger policy. Meanwhile, in analyzing the Performance variable, it is measured through Profit. After analyzing the structure-conduct performance (SCP) by assessing the impact of the sharia banking merger policy, it will be seen that the market is becoming more concentrated or becoming more competitive.
