One of the functions of the coastal ecosystem is to produce environmental services that can be used for marine tourism. Oil pollution incidents at the sea have caused a decline in the quality of marine tourism objects, thus reducing the number of visitors arriving and then it has implications for decreasing the income of the people who do business at tourist area. The community's claim for immediate compensation payments requires a faster calculation method. The purpose of this research is to develop a method of assessing the economic compensation for marine tourism businesses that are affected by incidents of oil pollution at the sea. The type of this research is descriptive research. The data consists of primary data and secondary data. The steps required in calculating compensation are (1) identifying tourism businesses, (2) building a theoretical concept of compensation, (3) determining the legal basis for calculating compensation, and (4) Designing a compensation formula. The application of the five compensation calculation formulas requires 18 variables. By taking the case of an oil spill incident in the North Sea of Karawang which has an impact on Tanjung Pakis beach tourism, an estimate of the value of compensation (Rp/day) is obtained for the buoy rental service business is Rp 111,323.08, for bathroom services business is Rp 69,504.62, for food/beverage trading business on a small scale is Rp 71,510.77 and for food/beverage trading business on a large scale is Rp 188,569.23. For the next stage, the implementation of compensation needs to be verified against the impacted community and the payment mechanism so that it is right on target.

Dinamika populasi merupakan aspek penting sebagai dasar pengelolaan perikanan dan informasi tentang aspek tersebut pada lobster pasir masih minim di perairan Palabuhanratu. Tujuan penelitian ini adalah mengkaji aspek pertumbuhan, pola rekrutmen, mortalitas dan laju eksploitasi lobster pasir (Panulirus homarus) di perairan Palabuhanratu. Penelitian ini dilakukan periode Juni 2015-Mei 2016 dengan metode sensus. Lobster pasir hasil tangkapan jaring insang dasar dengan jumlah total sampel 483 ekor mempunyai panjang karapas antara 28-100 mm. Pola pertumbuhan berdasarkan hasil regresi linear memperlihatkan allometrik negatif. Hasil analisis menggunakan metode ELEFAN I (Electronic Length Frequency Analysis) menunjukan koefisien pertumbuhan lobster pasir jantan (K = 0,29 per tahun), lebih kecil dibandingkan dengan betina (K = 0,40 per tahun). Rekrutmen terindikasi dua puncak dalam setahun: yaitu pada Februari-Mei dan September-Oktober). Laju mortalitaskarena penangkapan (F) mencapai 1,9-2,2 kali laju mortalitas alami (M). Nilai Lc<Lrmemperlihatkan lobster pasir sudah tertangkap sebelum mencapaiukuran rata-rata mengerami telur atau ukuran kematangan reproduktif. Laju eksploitasi lobster pasir mencapai 32-38% di atas laju eksploitasi optimum, sehingga lobster pasir sudah mengalamieksploitasi yang berlebih.Population dynamics is an important aspect as basic of fisheries management and little information of this aspect for spiny lobster fishery in Pelabuhanratu waters. This research aims to evaluate of growth aspects, recruitment pattern, mortality, and exploitation rate of scalloped spiny lobster (Panulirus homarus) in Palabuhanratu waters. This research was conducted in June 2015 until May 2016 using census method. The size of P. homarus captured using bottom gill-net with total sample 483 specimen was between 28-100 mm carapace lengths (CL). Linear regression showed that growth pattern was negative allometric. The growth coefficient of male (K = 0.29 per year) was found smaller than female (K = 0.40 per year) based on ELEFAN I (Electronic Length Frequency Analysis) method. Recruitment seems to be accrued twice peaks a year (February to May and September to October) and the highest was at February to May. Fishing mortality (F) reached 1.9 to 2.2 times of natural mortality (M). The LcÂLr value showed that female has been caught before reached the average size of bearing eggs or reproductive maturity size. The exploitation rate of spiny lobsters reaches 32-38% above optimum level. This study suggests that the spiny lobster fishery in Palabuhanratu in the state of overexploitation.

Freshwater crayfish (Cherax quadricarinatus) as an invasive species has high capability to adapt in most waters in Indonesia. The extant distribution of this species in Indonesia causes observation of morphological charactersÃÂ is important to be established. This study purpose is to compare the morphological characters of Cherax quadricarinatus from several locations in Indonesia waters, such as the river in Bintan Island, Toba Lake, and Lido Lake. The total of morphological characters was measured in twenty-two characters. The result of the Kruskal-Wallis test represented nine different characters between Toba, Bintan, and Lido. Cluster analysis illustrated the highest level of similarities between Toba and Lido. The growth rate of the dactyls, and carapace width, and ocular carapace length between Toba and Lido were similar, meanwhile between Toba and Bintan were different. C. quadricarinatus originating from river waters in Bintan Island has a different morphological character from Lake Lido and Lake Toba. The differences in morphological characters between locations are caused by differences in habitat characteristics in rivers and lakes.

Freshwater crayfish (Cherax quadricarinatus) is originate from Australia and Papua New Guinea waters. Morphometric measurement is one of the technique for differentiating body shape from a population. This study aimed to analyze the population kinship of freshwater crayfish in West Java with truss morphometric approach. Several morphometric characters were conducted measurement with a total of 133 individuals including 20 individuals from Darma Dam, 38 individuals from Kemang Lake, and 75 individuals from Kemuning Lake. The result of cluster analysis was obtained that the population of Cherax quadricarinatus from Kemuning Lake had closer relation with Kemang Lake than with Darma Reservoir. The differences in morphometric characters were alleged to be caused by differences of environmental conditions in three populations. Discriminant analysis showed that C. quadricarinatus from Darma Reservoir, Kemang Lake, and Kemuning Lake appropriately classified as 100%, 63.2%, and 76% respectively. Meanwhile, there were four main characters that differentiated the population from the three locations (C4, B5, D6, and A6).
