Diantara kedelapan gas tersebut, konsentrasi gas CO2 di atmosfer memiliki kontribusi terbesar yaitu lebih dari 55% dari total efek GRK yang ditimbulkan. Salah satu upaya pencegahan yang dapat dilakukan untuk menurunkan emisi GRK adalah dengan memanfaatkan lautan dan ekosistem pesisir sebagai penyerap CO2 alami (natural CO2 sink). Lamun merupakan tumbuhan laut yang berkontribusi terhadap penyerapan karbon melalui proses fotosintesis yang kemudian disimpan dalam bentuk biomassa pada bagian daun, rhizoma dan akar. Tujuan penelitian adalah untuk mengetahui jenis lamun, kerapatan dan tutupan lamun serta potensi penyerapan karbon dalam biomassa berupa jaringan atas substrat dan bawah substrat lamun yang dilakukan pada bulan Maret 2018 di Pulau Karimunjawa. Identifikasi jenis lamun dilakukan dengan melihat panduan buku seagrasswatch, kerapatan dan tutupan dilakukan dengan metode transek kuadran. Analisis kandungan karbon dilakukan dengan metode pengabuan. Hasil penelitian ditemukan 8 jenis lamun yaitu Enhalus acoroides, Cymodocea rotundata, Cymodocea serrulata, Thalassia hemprichii, Halophila minor, Halodule uninervis, Halophila ovalis dan Syringodium isoetifolium. Thalassia hemprichii dan Cymodocea rotundata memiliki nilai kerapatan tertinggi dengan kerapatan mencapai 450 ind/m2 dan 1204 ind/m2.

Total stok karbon di perairan Pulau Karimunjawa berkisar antara 1,28 ton karbon – 2,49 ton karbon atau sebesar 0,50 – 0,73 ton karbon/ha Climate change is caused by increasing greenhouse gases content such as carbon dioxide (CO2), chlorofluorocarbon (CFC), ozone (O3), dinitro oxide (N2O), methane (CH4), hexafluoride (SF6), hydrofluorocarbons (HFCS), perfluorocarbons (PFCS) )). Among the eight gases, the concentration of CO2 gas in the atmosphere has the largest contribution, which is more than 55% of the total GHG effects generated. One of the preventive measures that can be taken to reduce GHG emissions is to use the oceans and coastal ecosystems as natural CO2 sinks. Seagrass is a marine plant that contributes to carbon sequestration through photosynthesis which is then stored in the form of biomass in the leaves, rhizomes and roots.

Stasiun 1 berada di bagian Timur pulau, sedangkan Stasiun 2 berada di bagian Selatan pulau. Data kondisi vegetasi mangrovenya dikumpulkan dengan cara membuat transek garis dan plot berukuran 10 x 10 m2, 5 x 5 m2 dan 1 x 1 m2 yang ditarik dari titik acuan (tegakan mangrove terluar) dan tegak lurus garis pantai sampai ke daratan, sedangkan data kondisi biota asosiasi gastropodanya dikumpulkan dalam plot berukuran 1 x 1 m2 yang dipasang dalam plot transek vegetasi mangrove berukuran 10 x 10 m2. Kemudian distribusi mangrove, biota asosiasi gastropoda dan konektivitasnya dianalisis menggunakan Analisis Faktorial Koresponden (AFK). Hasil penelitian menunjukan bahwa terdapat 5 jenis mangrove dan 20 jenis biota asosiasi gastropoda. Kerapatan mangrove untuk kedua stasiunnya bervariasi, dimana untuk kategori pohon dan semai kerapatan tertingginya pada bagian Selatan, sedangkan kerapatan anakan pada bagian Timur. Sementara untuk biota asosiasi (gastropoda), kepadatan tertinggi untuk kedua stasiunnya adalah L. scabra (6,31 dan 2,24 ind/m2).

The research is included some activity to inventory the mangrove and sea gastropod as association biota with it’s spacial distribution and connectivity. It was conducted in Tunda Island Serang Banten on January, 2014 with the aim to collect biodiversity data in Indonesia. Station one (1) is on the East part of the island, while station two (2) on the South part. The mangrove vegetations condition data were collected by line transect and plot (10 x 10 m2, 5 x 5 m2 and 1 x 1 m2) method. It is pulled from the point reference direction (the outer mangrove stand) perpendicular to the shoreline from the main land and divided into 2 (two) research station located on east and south part of the island. While, the associations biota (sea gastropod) condition data were collected by plot size method (1 x 1 m2) located on man","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130777726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Target penangkapan dari alat tangkap Bubu salah satunya adalah Rajungan (Portunus pelagicus), yang merupakan komoditas ekonomis penting perikanan. Indikasi produktivitas suatu alat tangkap adalah apabila hasil tangkapan didominasi dengan target tangkapan dengan nilai efektivitas yang tinggi. Modifikasi bentuk dan jumlah Funnel (pintu masuk) pada Bubu merupakan salah satu cara memperbesar peluang target  masuk kedalamnya. Penelitian mengenai penambahan jumlah funnel bertujuan untuk meningkatkan peluang Rajungan tertangkap. Rancang bangun funnel sebanyak 6 buah (Bubu Payung) akan memperbesar peluang Rajungan sebagai target tangkapan tertangkap dibandingkan bubu dengan jumlah  funnel 2 buah. Melalui metode penelitian experimental fishing di perairan Rembang, Jawa Tengah didapatkan hasil bahwa Bubu dengan funnel sebanyak 6 buah (Bubu payung) menghasilkan hasil tangkapan lebih banyak dibandingkan dengan Bubu dengan funnel sebanyak 2 buah. Bubu was a passive fishing gear and kind of responsible fishing gear categories. Catch on fresh condition is one of benefit from this gear. Rajungan (Portunus pelagicus) is one of important fisheries resources and valuable. One of the productivity indicator on fishing gear is if catch dominated by targetted of fish and effectiveness value is high. Trap modification on shape and amount funnel is one of techniques to increase opportunity fish that get caught. The aim of this study is to increase opportuniy caught of Rajungan with different funnel amount. Bubu with six funnel will enlarge opportunity of Rajungan that caught than of two funnel. By experimental fishing in Rembang sea water, Province of  Central Java, the result of this study shown that bubu with six funnel get more larged rajungan catch than bubu with two funnel.","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130682150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine the effect of garlic extract addition as antibacterial and the characteristic of carrageenan edible film. The method was experimental laboratories with Completely Randomized Design with different concentration of garlic extract as the testing parameters. Data were analyzed using ANOVA then tested using Honestly Significance Difference (HSD) to determine the significance value of the sample. The result showed that the garlic extract was significant difference toward the antibacterial activities and the characteristic of carrageenan edible film. The result obtained from 7.5% garlic extract addition as antibacterial was the inhibition zone against S. aureus and E. coli of 3.00±0.100 mm and 2.18±0.07 mm; respectively.
