Abstrak: The presence of Pertamha UP IV Cilacap in Cilacap Regency has significant role in increasing economic contribution for public, directly and indirectly. In other hand, the activities Pertamina also has a negative impact from gilled which has polluted the waters territory of Cilacap. During period 2006-2008, it had four accidents of tanker shipwreck. Based on some research, those cases have impacted on the shrimp capture by fishermen and decreased the function of mangrove ecosystem In order to quantify the impact, it is important to value the economic loss in the area. The study aim to value of the economic loss imported by pollution using approach of bioeconomic model and the interlinkage of mangrove and shrimp especially for spawning and nursery grounds. The results shows that the value of economic loss of shrimps caused by oil spill in the area are Rp. 879,248,019,955.97 in the year of 2000 and Rp.882,853,204,695.74 in the Year of 2004. There are strong relation between mangrove area and productivity of shrimps which increasing of mangrove area per kilometer square has improved the productivity of shrimps equal to 50.12 tons. The decline of one kilometer square of mangrove has an impact to the productivity reduction of shrimps as 42.78 tons and causing loss of gross revenue of Rp. 909,652,686.67 per years.

Judul: Economic risk analysis of oil spill in the coastal waters of Cilacap: case study shrimp fisheries
Abstrak: Cilacap Regency is located at the Central Java has fisheries potential with high economic value and become a minapolitan area. The presence of Pertamina RU IV Cilacap at Cilacap Regency plays a significant role to economic contribution for public, both directly and indirectly. On the other hand, the activities Pertamina also create negative impacts from oil spill which has polluted the seat erritory of Cilacap:D uring period 2003-2011t,h erew ere four oil spills. Based on some researchest,h ose casesh ave impacted on the shrimp capture, effort and income of fishemren. Oil spill effects usually were not considered by decision maker and become environmental extemalities. In order to quantiff the impact, it is important to value of the economic lossed, the shrimp capture, effort decline in the area and the policy implication. The study aim to value of the economic loss impacted by oil spill using approach of bioeconomic model, producer surplus, and dynamic modeling. The result shows that the value of effort and shrimp capture decline of oil spill impact we 4.299 trip and 53,81 ton.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
