Pronghorn spiny lobster (Panulirus penicillatus) is one of the dominant lobsters and has high economic value. The fishing activities are conducted continuously and put aside the preservation of these resources. This study purposed to analyze the population dynamics of pronghorn spiny lobster (Panulirus penicillatus) in Pelabuhanratu Bay, Sukabumi, West Java. The data were collected from January until December 2016 with samples from local fisherman. Lobsters were measured carapace length and total weight. Data analysis included the relationship between length and weight, growth parameters, recruitment patterns, mortality, exploitation rate, length at first maturity or incubating eggs (Lr), and length for first capture (Lc). Panulirus penicillatus from the Palabuhanratu Bay has growth pattern of a negative allometric in both males and females. The asymptotic carapace length (CL∞) of males is higher than females while the growth coefficient (K) of males is lower than females. The peak recruitment for males is expected to be in April and July, while for females in May and August. The total mortality rate of males is higher than the natural mortality rate and vice versa for females. The male lobsters have occurred overexploitation, while females have not occurred overexploitation. The female lobsters have an Lr <Lc value which indicates that the female lobsters are caught after incubating the eggs.

Marine pollution can have a negative impact on aquaculture. For this reason, an appropriate and precise compensation calculation formula is needed. This study aims to formulate a formula for compensation calculating for aquaculture by reconstructing formula in PermenLH No. 7/2014. The reconstruction of formula was analyzed descriptively qualitatively with an expert judgement approach. The results showed that production data was a key factor in the reconstruction of compensation calculation formula. There are three reconstruction results formulas, namely compensation formula for aquaculture whose production data is available before and after pollution; compensation formula for aquaculture which only production data is available before pollution; and compensation formula for aquaculture which production data are not available

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.

Ekosistem lamun merupakan salah satu bagian penting sebagai bagian penyusun kesatuan ekosistem pesisir bersama dengan mangrove dan terumbu karang. Secara spesifik, keterkaitan masyarakat sebagai pemanfaat sumberdaya pada ekosistem lamun belum banyak diungkapkan. Tujuan dari penelitian ini adalah untuk mengkaji keterkaitan sistem sosial-ekologi lamun berdasarkan hasil tangkapan sumberdaya ikan di lokasi penelitian dan mengestimasi besaran manfaat sumberdaya ikan kaitannya dengan jasa ekosistem lamun di lokasi penelitian. Penelitian ini dilakukan dengan pendekatan kualitatif dan kuantitatif. Data yang dibutuhkan adalah data primer dan sekunder. Data primer didapat dari wawancara dengan instrumen kuisioner dan pencatatan hasil tangkapan dan penjualan di pedagang pengepul. Analisis data penelitian ini menggunakan metode analisis diskriptif kualitatif dan net fishing revenue (NFR) yang diperoleh nelayan. Hasil penelitian menunjukkan bahwa terdapat keterkaitan sosial-ekologi dengan keberadaan ekosistem lamun yang dijadikan sebagai tempat penangkapan bagi perikanan skala kecil yang bisa berkontribusi dalam ketahanan pangan dan sebagai mata pencaharian nelayan di desa tersebut. Manfaat yang didapat perikanan skala kecil dari keberadaan ekosistem lamun yaitu kemudahan akses bagi nelayan skala kecil dalam mencari ikan karena lokasinya yang dekat dengan pantai. Secara umum besaran manfaat dari fungsi ekosistem lamun sebagai jasa penyedia terlihat dari pendapatan per hari nelayan skala kecil diatas UMK Kabupaten Bintan yaitu Rp. 93,000,00. Dengan adanya keterkaitan sosial-ekologi lamun tersebut dapat dilakukan pertimbangan pengelolaan pesisir terpadu dengan pendekatan sosial-ekologi lamun di lokasi penelitian. (The Study of Seagrass Ecosystem and Small-Scale Fisheries Linkages (Case Studie: Malang Rapat and Berakit village, Bintan Regency,Riau Islands))Seagrass ecosystem is one of an important coastal ecosystem’s component along with mangroves and coral reefs. However, the linkage between fishers and seagrass ecosystem, had not been fully explored. The objectives of this research were analyze seagrass social-ecological system linkages based on fish caught and estimating the fisheries resource benefits regarding its ecosystem services at the study sites. Qualitative and quantitative approach based on primary and secondary data were used in this study. Data were collected by interviewed using questionaire and also production and sales records from sellers. Descriptive-qualitative and net fishing revenue (NFR) were used to analyze in this study. Results showed that there was a social and ecological linkage between seagrass and small scale fishers that could contribute to food security and livelihood at those sites. Accessibility of fishing ground on shores was one of the benefit for small scale fisheries. While ecological benefit of seagrass as a provisioning service was indicated by the daily small scale fishers’ revenue that was higher than The Minimum District Wage of Bintan District value which was IDR 93,000. Based on those social-ecological linkages, it is possible to use integrated coastal management with seagrass social-ecological approach in those sites.

Hasil survei potensi yang dilakukan IUCN dan LPSPL Sorong menunjukkan nilai kelimpahan ikan napoleon (Cheilinus undulatus) di Kabupaten Raja Ampat termasuk dalam kategori rendah. Walaupun demikian, nelayan tetap menginginkan ada kuota untuk pemanfaatannya karena merupakan salah satu sumber mata pencaharian utama. Aktivitas pemanfaatan harus disertai dengan upaya pengendalian untuk menjaga kelestarian sumberdaya. Penerapan upaya fishing control dan manajemen kebijakan belum dilakukan secara optimal, sehingga diperlukan penetapan berdasarkan skala prioritas. Tujuan penelitian ini adalah untuk mengidentifikasi kondisi pemanfaatan dan menentukan skala prioritas upaya untuk mengendalikan pemanfaatan ikan napoleon di Kabupaten Raja Ampat. Penentuan skala prioritas dianalisis dengan model Analytical Hierarchy Process (AHP) dengan melibatkan pakar di bidang konservasi dalam penilaian. Berdasarkan hasil identifikasi, kondisi pemanfaatan ikan napoleon di Kabupaten Raja Ampat dilakukan belum sesuai dengan ketentuan regulasi yang telah ditetapkan. Hasil penilaian dengan model AHP menunjukkan bahwa kriteria yang paling penting untuk mengendalikan pemanfaatan ikan napoleon adalah sumberdaya ikan lestari, dan urutan prioritas alternatif adalah sosialisasi kepada nelayan/pengusaha (bobot 0,2935), pengawasan (bobot 0,2715), survei kelimpahan secara berkala (bobot 0,2181) dan penerapan lalu lintas perdagangan melalui bandara (bobot 0,2169).The results of potential survey by IUCN and LPSPL Sorong showed the abundance value of napoleon fish (Cheilinus undulatus) in Raja Ampat Regency was low category. Nonetheless, the fisher quota for its utilization because it is one of the main sources of livelihood. The utilization activities should be followed by control of effort to maintain resource sustainability. Implementation of fishing control and management decisions has not been done optimally, therefore it need to be set based on priority scale. The purpose of this study were to identify conditions of utilization and to determine the priority scale to control utilization of napoleon wrasse fishery in Raja Ampat Regency. Determination of priority scale were analyzed with Analytical Hierarchy Process (AHP) model by involving experts in the field of conservation in the assessment. Based on the results of identification, the condition of the utilization of napoleon fish in Raja Ampat Regency was not with the regulation. The results of the assessment with AHP model showed that the most important criteria to control utilization of napoleon wrasse fishery is sustainable fish resources, and alternatives priority order are socialization/awareness program to fishers/live fish buyer (value 0.2935), surveillance (value 0.2715), periodic density surveys (value 0.2181) and implementation of trade air-only (value 0.2169).

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.

Perairan pesisir Lampung Timur merupakan salah satu daerah yang potensial untuk produksi rajungan (Portunus pelagicus) dari alam di Indonesia, namun produktivitas dan ukuran hasil tangkapan cenderung semakin menurun yang diduga akibat tingginya intensitas eksploitasi. Pada penelitian ini diinvestigasi komposisi kelamin dan ukuran rajungan yang tertangkap dengan jaring insang dasar (set gill-net) pada beberapa stratifikasi batimetri dari Maret 2012−Februari 2013. Area kajian dibagi menjadi 3 stratifikasi: S1, S2 dan S3 dengan kedalaman air masing-masing kurang dari 5 m, 5−10 m, dan lebih dari 10 m. Analisis data menggunakan statistik deskriptif. Rajungan jantan dominan tertangkap di seluruh stratifikasi area pengamatan. Ukuran rata-rata lebar karapas (CW) dan bobot tubuh (BW) rajungan [±SD] di strata S1 adalah 108,57 ± 13,39 mm dan 89,22 ± 35,33 g serta berbeda nyata dengan S2 dan S3 (P<0,05). Peningkatan ukuran lebar karapas dari S1 hingga S3 masing-masing 17,59% dan 14,62% serta bobot tubuh masing-masing 66,25% dan 57,24%. Terdapat sekitar 34% rajungan yang berukuran kecil dari Lm50 dan 24% dewasa kurang reproduktif yang tertangkap di S1. Perairan pesisir di S1 juga tampak sebagai daerah tangkapan utama rajungan, sehingga diperlukan strategi pengelolaan dengan mengimplementasikan perlindungan daerah asuhan dan pemanfaatan yang sangat selektif di area ini. The East Lampung coastal waters is one of potential area for the blue swimming crab (Portunus pelagicus) wild catch production in Indonesia. However, catch productivity and sizes of caught crabs tend to be decrease and might be related to high exploitation rate. In present study, we investigated the sex compositions and size distribution of this crab caught by the set gill-net at several bathimetric stratifications from March 2012 to February 2013. The study area was divided into three stratifications, i.e., S1, S2, and S3, which have had water depth less than 5 m, 5−10 m and more than 10 m, respectively. Data was analysed by descriptive statistics. The high proportion of males found in all stratification areas. Mean carapace width (CW) and body weight (BW) [±SD] of crabs were 108.57 ± 13.39 mm and 89.22 ± 35.33 g in S1and it was significantly different to that of S2 and S3 (P<0.05). An increasing of mean carapace width throughout S1 to S3 was 17.59% and 14.62%, whiles body weight was 66.25% and 57.24%, respectively. There were approximately 34% of immature crabs (less than Lm50) and 24% of less reproductive adults caught within S1. The coastal waters at S1 seem to be main fishing ground and management strategy by implementing a nursery ground protection and most selective fishing is required in this area.
