Diatoms are a type of microalgae with a quite strong potential in the health sector as antioxidants, anticancer, and antivirals. But until now in Indonesia is still very rarely carried out research on the antioxidant potential of diatoms. The purpose of this study was to determine the antioxidant potential of Amphora sp. extracted with methanol. The method used in the extraction process is maceration, with a ratio of sample and methanol 1: 3 (300 g: 900 ml). The evaporation process compacted maserate resulting from maceration, then analyzed the total chlorophyll content, total flavonoids, and total phenols. Amphora sp. extraction results showed good potential with 7.08 ppm chlorophyll content, total flavonoids 6,299 ppm, and total phenol 7,085 ppm, and IC50 DPPH values of 3332.5 ppm. The IC50 value of the extract of Amphora sp. still classified as very weak antioxidant activity, but in general the extract of Amphora sp. has other bioactive potentials such as chlorophyll, flavonoids, and total phenol which can be used as material for further studies for the development of natural medicinal ingredients from Amphora sp.Key words: antioxidant, diatome, DPPH, macaration, methanol.

Intensive shrimp farms need mangroves to increase the carrying capacity of their waters. Every 1 Ha of intensive shrimp pond requires 7.2 Ha mangrove to absorb nitrogen (N) and 21,7 Ha to absorb phosphor (P) from waste water disposal. This study was conducted to estimate the extent of lmangrove required to absorb nitrogen (N) and phosphorus (P) wastes removed from intensive shrimp farming in Banyuputih Subdistrict of Situbondo Regency. From the field survey results obtained data on the area of productive intensive ponds in the District Banyuputih is 39 Ha. The result of data analysis indicate that 280,3 Ha mangrove is needed to support the absorption of nitrogen (N) and 846,3 Ha mangrove to absorb phosphorus (P) of effectiveness pond waste pond in the study area. The mangrove in this subdistrict of Banyuputih (540,18 Ha) still support in the absorption of nitrogen waste (N), but for the absorption of phosphorus posfor (P) ponds still needed reforestation of at least 304,12 Ha from the existing mangrove area. If the local government intends to develop intensive shrimp ponds in accordance with the carrying capacity or maximum capacity of coastal waters of Banyuputih in decomposing 58 ha of tambak organic ponds, the current mangrove condition (540.18 Ha) still supports the absorption of nitrogen (N) from ponds intensively covering an area of 58 Ha, but to absorb the posfor (P) lagoon is still needed addition (reforestation) of 718.42 Ha.
