Alat tangkap Bagan digunakan untuk menangkap ikan phototaxis positif. Lampu sebagai alat bantu pengumpul ikan pada bagan dianggap tidak efektif dan efisien karena membutuhkan waktu yang cukup lama untuk mengumpulkan ikan. Apabila masalah tersebut dibiarkan maka dapat berdampak terhadap peningkatan kebutuhan bahan bakar minyak (BBM) sebagai sumber energi lampu. Penambahan atraktor cumi (fish aggregating device) pada bagan merupakan solusi dalam operasi penangkapan. Tujuan penelitian adalah mengetahui dan menganalisis pengaruh penggunaan atraktor cumi terhadap hasil tangkapan Bagan tancap (lift net) diperairan Jepara. Metode yang digunakan pada penelitian ini adalah metode eksperimen dengan pengulangan sebanyak 16 kali. Jumlah hasil tangkapan Bagan tancap yang tanpa menggunakan atraktor cumi adalah Cumi (38,55 kg), Ikan Teri (22,55 kg), Kepiting (2,3 kg) dan Udang (2,03 kg). Sedangkan pada Bagan tancap yang menggunakan atraktor cumi hasil tangkapannya adalah Cumi (46,62 kg), Teri (40,82 kg), Kepiting (4,5 kg) dan Udang (1,2 kg). Common fishing gear who uses to catch positive phototaxis fish is Lift Net. The lamp was no longer used as the fish aggregating device for lift net because it was ineffective and inefficient to gathered fish target. If the problem still continued it can increased fuels consumption for lamp attractor. Another fish aggregating device “Squid Attractor” was a solution for lift net operation. The objective of this research was to analyze Squid Attractor's effect of Lift Net catch in Jepara seawaters. The Method used in this research is experimental fishing with 16 repetitions. This research showed Lift Nets catch without Squid Attractors is less than Lift Nets with Squid Attractor's, there is 38.55 kg of squid, 22.55 kg of anchovies, 2.3 kg of crabs and 2.03 of shrimps. Whereas Lift Net with squid attractor got bigger catch such as 46.62 kg of squid, 40.82 kg of anchovie,s 4.5 kg of crabs and 1.2 kg of shrimps.

The shrimp culture is collapsing at Jepara coast. Several internal and external reasons have caused this and are needed to be handled seriously. An alternative solution should be conducted and applied without delay. Recent Existing condition of the shrimp culture at Jepara Coast is experiencing a tremendous decline in the last five years. There are four category of internal factors determinant which shows this decline: the development of shrimp culture production, the development of shrimp culture available cultivation area, shrimp culture number of units, and the development of the farmers’ internal revenue. The degradation of the shrimp culture at Jepara coast is mainly caused by environmental and managerial reasons. The environment is no longer supporting the shrimp culture at Jepara coast and to overcome this, a relocation or re-zonation should be applied. As alternative solution, to regain the Jepara region’s aquaculture potencies, a new species can be introduced and applied. In order to develop new species and to sustain its productivity, the new species should have some characteristics as follows: easy to culture, invulnerable to disease, high market demand, high market price, short cultivation period, low production cost, and able to adapt with unfortunate water quality. Key words : Shrimp culture condition, Jepara coast

Perubahan iklim disebabkan karena meningkatnya kandungan Gas Rumah Kaca seperti karbon dioksida (CO2), klorofluorokarbon (CFC), ozon (O3), dinitro oksida (N2O), metana (CH4), heksafluorida (SF6), hidrofluorokarbon (HFCS), perfluorokarbon (PFCS)). 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. Nilai biomassa dibagian bawah susbtrat berkisar 970,39 - 1.412.55 gbk/m2 yang lebih besar dibandingkan nilai biomassa lamun dibagian atas substrat berkisar 371, 88 - 546, 38 gbk/m2 diikuti nilai penyerapan karbon dibagian bawah substrat (akar dan rhizoma) berkisar antara 12,60 – 93,62 gC/m2, sementara kandungan karbon dibagian atas substrat (daun) berkisar antara 4,19 – 34,12 gC/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. This research aims to know the types of seagrass, seagrass cover and potential density of biomass carbon of above the substrate (leaves) and below the substrate seagrass (roots and rhizomes) in March 2018 at Karimunjawa Island. The identification of seagrass types used guidance book of seagrasswatch and the identification of seagrass cover and density was carried out using transect quadrant method. Analysis carbon content used ashing method. The result of the present study found 8 species of seagrasses that Enhalus acoroides, Cymodocea rotundata, Cymodocea serrulata, Thalassia hemprichii, Halophila minor, Halodule uninervis, Halodule ovalis and Syringodium isoetifolium. Thalassia hemprichii and Cymodocea rotundata have the highest density value reached 450 ind/m2 and 1,204 ind/m2. Value biomass below substrate ranged from 970.39 to 1.412.55 gbk/m2 which is greater than the value biomass above the substrate ranged from 371, 88 - 546, 38 gbk/m2 followed by the value of the carbon adsorption in below the substrate (roots and rhizomes) ranged from 12.60 to 93.63 gC/m2, whilst the carbon content above the substrate (leaves) ranged from 4.19 to 34.12 gC/m2. Total carbon stock in the waters of Karimunjawa Island ranged from 1.28 – 2.49 tons of carbon or of 0.50 to 0.73 tons of carbon/ha.
