Coastal areas (especially small islands) are vulnerable to impact from sea level rise (SLR). The submergence of areas that are economic centers will impactin huge losses. To avoid such losses it is necessary to manage small islands by using temporal spatial models. The aim of this article is to describe the development of a temporal spatial model to assess the vulnerability of settlements in small islands. The method used is dynamic system modeling combined with Geographic Information System (GIS) based on identification of environmental issues and conditions in small island, in this case Karimunjawa Island and Kemujan Island, Jepara Regency. The assumption used in the modeling is that there is no natural disaster or calamity that reduces the population, the death is considered normal death by referring to the average life expectancy of the Indonesian population (69 years), no coastal reclamation activities, no significant changes in ecosystem. The modeling results indicate that if the fraction of SLR 10 cm per year, will have an impact on the decreasing availability of settlement land. The height of SLR ranges from 0,5 meters in the 10th year, to 5,0 meters in the 100th year. As a result there will be puddle in the residential area of 13,02 ha in the 10th year and in the 100th year to 226,5 ha. Required environmental engineering efforts,such as develop coastal dike and reform plan of building, to reduce impact on the availability of settlement land. SLR that is affecting populations and settlements on Karimunjawa and Kemujan Island, require adaptation as an impact mitigation effort. Wilayah pesisir (terutama pulau kecil) sangat rentan terkena dampak dari peningkatan muka air laut. Terendamnya wilayah-wilayah yang merupakan sentra ekonomi akan mengakibatkan kerugian yang sangat besar. Untuk menghindari kerugian tersebut perlu pengelolaan pulau-pulau kecil dengan memanfaatkan model spasial dinamik/temporal. Tujuan studi adalah mengembangkan model spasial dinamik/temporal untuk mengkaji kerentanan permukiman penduduk di pulau-pulau kecil. Metode yang digunakan adalah pemodelan sistem dinamik/temporal (SD) dipadukan dengan Sistem Informasi Geografis (SIG) berdasarkan identifikasi isu dan kondisi lingkungan di pulau kecil, yaitu Pulau Karimunjawa dan Pulau Kemujan, Kabupaten Jepara. Data yang digunakan adalah data pertumbuhan penduduk (data sekunder) dan peta dasar Pulau Karimunjawa dan Kemujan. Asumsi yang digunakan pada pemodelan adalah tidak terjadi bencana alam atau musibah yang mengurangi jumlah penduduk, kematian dianggap sebagai kematian normal dengan mengacu umur rata-rata harapan hidup penduduk Indonesia (69 tahun), tidak ada kegiatan reklamasi pantai, tidak ada perubahan ekosistem secara signifikan. Pemodelan spasial dinamik/temporal mengikuti tahapan sesuai dengan prosedur pemodelan. Hasil pemodelan menunjukkan bahwa bila fraksi sea level rise (SLR) 10 cm per tahun, akan berdampak pada penurunan ketersediaan lahan permukiman. Tinggi kenaikan muka air laut berkisar antara 0,5 meter pada tahun ke-10, hingga mencapai ketinggian kenaikan 5,0 meter pada tahun ke-100. Akibatnya akan terjadi genangan air laut di permukiman penduduk seluas 13,02 ha pada tahun ke-10  danpada tahun ke-100 menjadi 226,5 ha. Diperlukan upaya rekayasa lingkungan, seperti membangun tanggul pantai dan memperbaiki rancangan konstruksi bangunan permukiman, agar dapat mengurangi dampak terhadap ketersediaan lahan permukiman. Kenaikan muka air laut yang berdampak terhadap penduduk dan permukiman di Pulau Karimunjawa dan Kemujan membutuhkan adanya adaptasi sebagai upaya mitigasi dampak.

Tujuan penelitian ini adalah untuk mengkaji nutrisi yang terdapat pada limbah ikan sidat (Anguilla marmorata) yang dapat dimanfaatkan ikan lele (Clarias sp.) sebagai pakan tambahan. Penelitian ini menggunakan rancangan acak lengkap yang terdiri dari 2 perlakuan dengan masing-masing 3 ulangan. Pemeliharaan dilakukan selama 30 hari. Jumlah ikan yang ditebar adalah 5 ekor/akuarium. Akuarium yang digunakan berukuran 30x40x50cm. Perlakuan A: pemeliharaan ikan lele dengan pakan komersil 3% dari biomassa, perlakuan B: pemeliharaan lele dengan pakan komersil 1% dari biomassa ditambahkan limbah sidat cair 3 liter/3 hari. Hasil pengujian kandungan nutrisi pada limbah sidat cair memiliki nilai protein sebesar 4% dengan kandungan amoniak sebesar 0,037 mg/L. Nilai SR ikan lele pada masing-masing perlakuan adalah 100%. Laju pertumbuhan spesifik pada perlakuan A sebesar 2,31% sedangkan pada perlakuan B sebesar 1,63%. Â Biomassa ikan lele pada perlakuan A mengalami peningkatan sebesar 100% sementara perlakuan B biomassa ikan lele meningkat 65%. Namun berdasarkan hasil analisis statistik menunjukkan bahwa tidak ada perbedaan nyata antar perlakuan (p>0,05) baik itu pada pengujian sintasan, laju pertumbuhan spesifik maupun konversi pakan. Hal ini menunjukkan bahwa pemanfaatan limbah ikan sidat dapat mendukung peningkatan pertumbuhan ikan lele.Kata kunci: ikan lele, limbah pemeliharaan Â ikan sidat, pakan.Â

Although frequently described as low-fertility or low-productivity habitat, coastal mudflats serve as important feeding grounds for fish. Many fish species from adjacent coral reefs, seagrass beds, or mangroves foraging periodically in mudflats. Because of this foraging behaviour, some local fishermen are known to utilize the mudflats to catch fish. However, the impact of this catching activities to the ecosystem has not been fully discovered. An examination of the fish community structure and levels of environmental stress had carried out in the mudflat ecosystem of the coast of Kaledupa Island in Wakatobi National Park (WNP), Indonesia. Two mudflat study sites were selected from the shore of Balasuna and Tampara villages located between mangroves and coral reefs. Data were sampled from the fish catch of local fishermen using fish fences (sero) installed in each mudflat area. Fish community structure was analyzed using diversity index and index of relative importance (IRI). ABC curves and species exploitation rate were used to assess the local environmental pressure. A total of 74 fish species were recorded from the mudflats of Kaledupa, which was found to be dominated by reef-associated fish species, comprising 63 species and accounting for 85% of the total catch. Additionally, although both sites had relatively high reef fish diversity, the obtained Clarke’s W-statistic values were approximately 0, indicating that the local fish communities presented moderate levels of disturbance. Three out of five fish species with the highest IRI values were found to be over-exploited, namely Siganus canaliculatus, Lethrinus ornatus, and Lethrinus variegatus.

Pemanfaatan sumber daya di wilayah pesisir mencakup konteks sosial multiple use, berbagai bentuk kepemilikan, dan konflik atas penggunaan sumber daya. Sistem ekologi di daerah pesisir sangat berhubungan erat dengan/dan dipengaruhi oleh satu atau lebih sistem sosial. Pendekatan kontemporer pengelolaan pesisir dan lautan berbasis sosial - ekologi pada dasarnya adalah integrasi antara pemahaman ekologi (ecological understanding) dan nilai – nilai sosial ekonomi (socio-economic value). Analisis sistem ekologi-sosial (SES) dalam pengelolaan wilayah pesisir terpadu mampu memberikan suatu pendekatan yang interdisipliner dan framework pengelolaan sumber daya yang berkelanjutan. Analisis SES dapat menjadi basis pengetahuan untuk mengatasi secara sistematis masalah yang kompleks dalam pengelolaan pesisir secara terpadu, selain itu juga dapat mengembangkan suatu strategi berbasis pengetahuan dalam memahami proses-proses ekologi dan sosial pada dimensi sistem dan skala yang berbeda.Title: Social – Ecological System (SES) Approach In Integrated Coastal ManagementUtilization of resources in coastal areas includes multiple use social contexts, various forms of ownership, and conflicts of interest. The purpose of this paper is to learn about the Social-Ecological System approach in integrated coastal management. Ecological systems in coastal areas have a very close relationship with / and are influenced by the social system. Basically the contemporary approach of coastal management based on social-ecology system (SES) is the integration between ecological understanding and socio-economic value. SES analysis in integrated coastal area management is able to provide an interdisciplinary approach and a sustainable resource management framework. SES analysis can be a knowledge base for dealing systematically with complex problems in integrated coastal management, while also developing a knowledge-based strategy in understanding ecological and social processes in different dimensions of the system and scale.

Sektor perikanan tangkap memiliki peran penting dalam upaya meningkatkan ekonomi masyarakat. Salah satunya dengan pengembangan usaha nelayan skala kecil. Penelitian ini bertujuan untuk mengetahui potensi pengembangan usaha perikanan skala kecil dan menganalisis tingkat efisiensi jenis alat tangkap nelayan. Penelitian dilakukan di Kabupaten Kolaka, Provinsi Sulawesi Tenggara. Data yang digunakan adalah data primer berdasarkan hasil wawancara langsung di lapangan serta data sekunder dikumpulkan dari instansi pemerintah terkait. Kegiatan usaha perikanan tangkap skala kecil, khususnya pada alat tangkap pancing tonda dan rawai dasar, memiliki nilai efisiensi yang rendah jika dilihat dari nilai profitabilitasnya, yaitu 20% dan 30%, jika dibandingkan dengan alat tangkap jala jatuh berkapal dan bagan dengan nilai profitabilitas, yaitu 40% dan 50%. Secara umum, perikanan skala kecil di Kolaka masih sangat memiliki ketergantungan dengan pemilik modal usaha untuk menjalankan kegiatan perikanan. Pengembangan usaha perikanan, khususnya pada alat tangkap yang memiliki nilai efisiensi rendah, perlu bantuan modal yang besar untuk meningkatkan nilai pendapatannya. Kebijakan perikanan skala kecil di Kabupaten Kolaka dikelola oleh Unit Pelaksana Teknis Dinas (UPTD) Perikanan Tangkap, khususnya pada bidang pemberdayaan nelayan skala kecil. Title: Analysis of Small Scale Catch Fisheries Business in Kolaka District, South SulawesiThe capture fisheries sector has an important role in efforts to improve the community’s economy, one of which is the development of small-scale fishing businesses. This study aims to determine the potential for developing small-scale fisheries and to analyze the efficiency level of types of fishing gear. The research location is in Kolaka Regency, Southeast Sulawesi Province, the data used is primary data based on the results of direct interviews in the field and secondary data collected from relevant government agencies. Small-scale capture fishery business activities, especially in line fishing gear and basic longlines, have low-efficiency values seen from their profitability values, namely 20%, and 30% compared to fishing gear, Jalah Jatu, and boats, with profitability values of 40% and 50%, respectively. In general, small-scale fisheries in Kolaka are still very dependent on business capital owners to carry out fishing activities. The development of fisheries business, especially in fishing gear that has a low-efficiency value, requires large capital assistance to increase the value of its income. Small-scale fisheries policies in Kolaka Regency are managed by the Capture Fisheries Technical Implementation Unit, especially in the field of empowering small-scale fishermen.

Â Impact conflict social in a conservation areaÂ is generally more significant in the islands minor because competition limits space and resources. Objective study This is a complete stakeholder analysis of the interests (stakeholders) involved in the utilization of land and resources in nature. Data used in studies mapping conflict social This consists of two types, namely qualitative data related to the existence of the stakeholder's interests and spatial data. Qualitative data obtained from studies literature results in research, observation field, and interviews deep with the critical actor (key actor). At the same time, spatial data is an Island LULC Kaledupa 2016 (result in classification guided Landsat 8 imagery OLI), and derived MSP from map topography island (result in SRTM data analysis). Utilization stakeholder resource nature and management area on the Island Kaledupa shared into five categories: authority manager area conservation, Institution Central Government (Ministry of Maritime Affairs and Fisheries), government area Wakatobi, social economy local, and nongovernmental organizations. Mapping conflict utilization resource nature and management area on the Island Kaledupa is beneficial in formulating input consensus policy among all stakeholders.

Coral reefs are marine resources that are most vulnerable to disturbances from both human and natural activities. Fishing activities that are not environmentally friendly such as bombardment and potassium are still found in coastal areas and threaten the resources in the conservation area. This research will look at the health condition of coral reefs in conservation areas, especially in local utilization zones. In this zone the activity of exploiting marine resources is very high, therefore data is needed to find out and prove whether the use of marine resources is damaging. Locations were selected at four stations on Lentea Island which are included in the local use zone in the conservation area. The assessment uses the PIT (Point Intercept Transect) method. The results of the assessment showed that the coral reefs on Lentea Island were in the bad to good category (24.0% -50.3%). This data shows that there are still destructive marine resource utilization activities in the local utilization zone.

Mangrove ecosystem can absorb and store carbon stock in their biomass and sediment. This ecosystem plays an important role in the carbon cycle. This study aimed to analyze the C-organic content and organic carbon stock of sediment, also CO2 absorption. The sediment sampling was conducted in the Kolaka Coastal line mangroves using a Peat Auger for 1 m of sediment depth. Then the sediment was separated into four layers. Then the sediment samples were oven dried at 50°C for 1 week for sediment bulk density analysis (SBD). The analysis of the C-organic content of sediment was done by the LOI method. The estimation of sediment carbon stock using sediment C-organic data and SBD data. The results showed that the highest average of C-organic content was in station 3 (4.12±0.15%). In the othher hand, the highest average of SBD was in station 1 (0.67±0.02 g cm-3). Overall, the total of sediment C-organic stock in station 1 was higher than other station (233.67±11.90 Mg C ha-1). The total capacity of CO2 absorption by sediment in the station 1 was also higher than other station (856.77±37.66 Mg CO2 ha-1). The sediment C-organic stock was influenced by C-organic content and SBD value.
