Penelitian ini dilaksanakan pada bulan Februari - Maret 2017 di perairan pesisir Kampung Oransbari, Kabupaten Manokwari Selatan, Provinsi Papua Barat. Tujuan penelitian ini mengetahui komposisi jenis ikan karang, keanekaragaman jenis ikan karang, kelimpahan dan biomassa ikan karang. Proses pendataan kelimpahan ikan karang menggunakan metode sensus visual ikan (Underwater Fish Visual Census Method) (English et al, 1994), dimana secara teknis dilakukan dengan metode transek sabuk (Belt Transect). Total ikan karang yang tercatat adalah 6224 individu, tergolong dalam 9 famili, 11 genus dan 22 spesies dimana total individu stasiun I sebanyak 1174 dan 5050 individu pada stasiun II. Komposisi ikan karang tergolong dalam 9 famili (Haemullidae, Mullidae, Scaridae, Lutjanidae, Caesionidae, Acanthuridae, Siganidae, Serranidae dan Sphyraenidae), 11 genus (Plectorinchus, Parupeneus, Mulloides, Scarus, Choerodon, Lutjanus, Caesio, Ctenochaetus, Siganus, Cephalopholis, dan Sphyraena), dan terdiri dari 22 spesies (Plectorinchus lineatus, Plectorinchus chrysotaenia, Parupeneus bifasciatus, Mulloides flavolineatus, Scarus sp., Scarus bleekeri, Scarus flavipectoralis, Scarus quoyi, Choerodon anchorago, Lutjanus gibbus, Lutjanus quinquelineatus, Lutjanus semicinctus, Lutjanus erythropterus, Lutjanus rivulatus, Caesio lunaris, Caesio teres, Ctenochaetus striatus, Ctenochaetus tominiensis, Siganus doliatus, Siganus guttatus, Cephalopholis miniata, dan Sphyraena barracuda). Nilai indeks keanekaragaman pada stasiun I sebesar 3,03 dan 3,61 pada stasiun II, selanjutnya nilai indeks keseragaman pada stasiun I sebesar 1,12 dan 1,17 pada stasiun II, serta nilai indeks dominansi pada stasiun I sebesar 0,10 dan 0,08 pada stasiun II. Kelimpahan total ikan karang yang termasuk dalam kategori spesies target pada stasiun I yaitu 46.960 individu/ha dengan estimasi biomassa sebesar 188.528,7 Kg/ha. Selanjutnya pada stasiun II kelimpahan total ikan karang mencapai 202.000 individu/ha serta estimasi biomassa sebesar 335.045,4 Kg/ha.
Ekosistem lamun memberikan jasa lingkungan bagi masyarakat yang didefinisikan sebagai semua manfaat yang berguna bagi kesejahteraan masyarakat pesisir. Penelitian ini dilakukan di pesisir Numfor Papua, kampung kornasoren dan Yenburwo selama bulan Juni–Juli 2016. Tujuan penelitian ini yaitu untuk mengkaji potensi dan jasa ekosistem lamun bagi kesejahteraan masyarakat. Sebanyak delapan jenis lamun ditemukan E. acoroides, T. hemprichii, C. serrulata, C. rotundata, H. ovalis, H. pinifolia, H. uninervis, dan S. isoetifolium. Jenis T. hemprichii dan E. acoroides memiliki tegakan tertinggi. H. pinifolia dan H. uninervis adalah jenis lamun tegakan terendah. Nilai persentase penutupan relatif terbesar yaitu E. acoroides sebesar 37,34%. Indeks Nilai Penting jenis T. hemprichii 92,34 dikampung Kornasoren, sedangkan di kampung Yenburwo E. acoroides, yaitu 90,10. Bahan untuk buat jaring, pengumpulan moluska, penangkapan ikan, dan pengumpulan teripang merupakan bentuk pemanfaatan masyarakat pada ekosistem lamun. Terdapat hubungan pengaruh yang signifikan antara aktivitas pemanfaatan masyarakat terhadap persen penutupan lamun. Terdapat hubungan pengaruh yang signifikan (p-Value = 0,03< α = 0,05) antara aktivitas pemanfaatan masyarakat terhadap persen penutupan lamun di Kampung Kornasoren dan Yemburwo. Hasil kajian ini membuktikan bahwa perlu dilakukan pengelolaan ekosistem lamun secara komprehensif, baik aspek ekologi, sosial, dan ekonomi untuk mencapai tujuan pembangunan berkelanjutan.
Seagrass ecosystem have primary and secondary productivity with great support to the abundance and diversity of fishes and it’s biota associations. Seagrass ecosystems are also as a coastal resources that have an important role of environmental services. Some community activities will directly or indirectly can have an impact on habitat degradation and biodiversity of seagrass ecosystems. The importance oto assess the potential of seagrass ecosystem and it’s biotas association is to know of sea grass’s role to provides of environmental services is the aim of this study. This research was conducted in the waters of Kampung Aisandami, Teluk Wondama Regency during June - July 2019. Data collection methodology was used is structured random methods quadrant transects at two observations to reveal data on seagrass community structure. The datas obtained were tabulated and displayed in tables and figures. Thalassia hemprichii and Enhalus acoroides were found at two observation sites. Another type found outside the observation transect is Halophila ovalis. E. acoroides seagrass species have a frequency value is 0.77 which shows that distribution of E. acoroides is wider than T. hemprichii which has a frequency is 0. 58. Both of station show that T. hemprichii has a frequency value of 0.7 where it indicates that distribution is wider compare with E. Acoroides. T hemprichii has the highest relative density at both observation stations. The status of seagrass of both stations is classified as poor or unhealthy with seagrass value ≥ 30-59.9%. The highest importance index is the T. hemprichii seagrass at both stations and has a higher role than the E. acoroides. The community-based management model is the a suitable model that can be used to developing coastal ecosystem management including seagrass ecosystems in this village.
Marine tourism is a type of special interest tourism, namely by managing and utilizing marine and coastal landscapes, both those that are managed directly such as swimming, boating, snorkeling, diving, or indirectly such as picnics and beach sports. Nusmapi Island has the potential to be developed as a marine tourism object which has the potential for waters and coral reefs that are in good condition. The purpose of this study was to determine the relationship between the level of public perception and the socio-economic conditions of the local community on Nusmapi Island. In October-November 2020 this research was carried out on Nusmapi Island, Manokwari Regency. The descriptive exploratory method is by conducting a survey to the research location. The data collected were analyzed descriptively by tabulating and displayed in the form of pictures, tables, and graphs to provide an explanation of the information obtained in this study. The relationship between the level of perception and socio-economic and cultural aspects of society was analyzed by multiple regression. The variables of age, gender, education, main occupation, and additional work were positively correlated with community perception, while length of stay and ethnic origin were negatively correlated with perceived level. The correlation value between the 7 independent variables (X1-X7) and the dependent variable (Y) is 0.839 which is included in the very strong category. The value of the coefficient of determination 61% explains the variables in the resulting regression model, the remaining 39% is influenced by other factors outside the model. Age is a significant social variable on people's perceptions of the development of marine tourism on Nusmapi Island. The community as the main component in development has an important role in developing local potential that comes from nature, socio-culture or improving the community's economy through the development of marine tourism.
West Papua's fishery resources are in fishery management areas 715 and 717 with a potential of 1,242,526 tonnes/ha and 1,054,695 tonnes/ha respectively. On average, most fishery products are marketed fresh and only 1.20% are in the form of further processing. Therefore, the analysis of small and medium fisheries industries’ (SMFI) development framework is needed to encourage small and medium fisheries enterprises to grow and be sustainable. The analytical framework is realized by considering the initial data consisting of household capacity of fishermen, product superiority, and maximum sustainable yield; data management and processing; support from legal policy; community-based institutions; and co-management arrangements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
