Microalgae harvesting is an important part in microalgae cultivation system. Techniques for harvesting marine microalgae which are commonly used are centrifugation, filtration and flocculation. These techniques still have some disadvantages, such as not environment friendly, and high usage of energy and cost. Bio-flocculation harvesting technique using microalgae as a flocculant agent can be an alternative way to solve these problems. In this research, mixing of Tetraselmis suecica (flocculant) with Chlorellasp. and Nannochloropsis sp. (non-flocculant) in ratios of 1:4, 2:4, 3:4 and 4:4 (v/v) has been conducted to obtain percent recovery of marine microalgae harvest. The results showed that T. suecica as flocculant agent can fasten the harvesting of Chlorella sp. and Nannochloropsis sp. It was shown by the increase of percent recovery value of Chlorellasp. from 51.14 ± 1.07% to 67.34 ± 0.67% and Nannochloropsis sp. from 20.52 ± 1.17% to 42.43 ± 0.40% during the first hour of flocculating process. Our result showed that bio-flocculation is an environment friendly technique which can be applied to harvest marine microalgae.

A study was carried out to assess the present status of blue swimmer crab (Portunus pelagicus) in Lancang Island, incorporating identification of fishing ground, also measurement of environmental condition and crab biometry. Monthly catch assessment was performed on JuneSeptember 2015 at three landing bases using structured questionnaire and morphometric sampling of minimum randomly selected 30 crabs. Bathymetric survey was conducted to produce depth-contoured maps combined with certain oceanographic parameters (sea surface temperature, salinity, water clarity, total suspended solids, dissolved oxygen, and nitrate-NO3) measured at 15 sampling sites. A grid map was produced to identify key areas of crab fishing grounds, recruitment habitat, and spawning habitats. During southeast monsoon, main fishing ground was distributed in the western and southern part of Lancang Island (grid C3, C4, and D5). In general, crab yields were dominated by female (66.9%) and 43.8% of them were bearing eggs. Four size classes were determined from frequency distribution of carapace width (Class 1 = 7.0-10.6 cm; Class 2 = 10.7-14.2 cm; Class 3 = 14.3-17.8 cm; and Class 4 = 17.9-21.5 cm), with Class 2 as the most prominent catch. Referring to ontogenetic migration trait of the species, presumed recruitment habitat for blue swimmer crab in Lancang Island is located at A6, where abundant juveniles were harvested in the area with strong oceanic influence and depth range of 24-30 m. Spatial coherence on the distribution of bearing egg female with several environmental parameters (sea surface temperature, salinity, and dissolved oxygen) indicates strong estuarine influence is required for crab spawning habitat at C3 and

Light and nutrient are factors that support the microalgae growth rate besides COB2B, temperature, and salinity. Microalgae growth of Chorella sp. and Dunaliella sp. were observed to determine the influences of different nutrient concentration and photo period. Microalgae cultivation was located at laboratory using 100 mL Erlenmeyer. The specific growth rate of microalgae was observed for different nutrient concentration and photo period of light treatments. Using Guillard/f2 nutrient, the highest specific growth rate for Chorella sp. was 0.227/d and 0.289/d for Dunaliella sp. The highest microalgae specific growth rate influenced different photo period was 0.39/d and 0.329/d, respectively. Finally, the highest specific growth rate for both cultivated species of microalgae was observed at 2V nutrient concentration and 24 hour period of light treatment.Keywords : Spesific growth rate, photoperiod, nutrient, Chlorella sp., Dunaliella sp.

The need for data and information about benthic habitat is very necessary to maintain and conserve the ecosystems that exist in the waters. Damage to benthic habitats can occur due to anthropogenic activities and natural disasters that will impact on the surrounding biota and ecosystem, therefore to know and monitor the condition of waters and shallow water habitats it is necessary to do mapping. This study aims to detect the change of benthic habitats in Karang Lebar, Kepulauan Seribu. This study utilized high resolution multispectral imagery QuickBird (2008) and WordView-2 (2018) to detect changes in the distribution and the area of the benthic habitat coverage at the study site. The classification of multispectral imagery was carried out with two approaches, namely the application of the Support Vector Machine (SVM) algorithm and Depth Invariant Index (DII) transformation on both satellite imageries. The number of benthic habitat classes produced was five classes, namely live coral, dead coral, seagrass beds, sand, and rubble. The results of the analysis showed an overall accuracy of 58.18% and 70.9% in the classification with multispectral input bands for the 2008 and 2018 imagery, and 60% and 80% for the DII transformation on 2008 and 2018 imageries respectively. The results of change detection showed the rubble class to sand had the largest area of 81.46 ha.

Habitat perairan dangkal sangat penting dipetakan diantaranya karena: (1) mendukung perencanaan, manajemen, dan pengambilan keputusan tata ruang pemerintah; (2) mendukung dan mendesain Marine Protected Area (MPA); (3) melakukan program penelitian ilmiah yang bertujuan untuk menghasilkan pengetahuan tentang ekosistem bentik dan geologi dasar laut; (4) melakukan penilaian sumber daya dasar laut yang hidup dan tidak hidup untuk tujuan ekonomi dan menajemen, termasuk rancangan cadangan perikanan. Hingga saat ini belum ada standar untuk tingkat kedetailan peta tematik ekosistem pesisir khususnya habitat perairan dangkal sesuai kebutuhan pengelolaan wilayah pesisir dengan skema klasifikasi tertentu. Penelitian ini bertujuan untuk membandingkan akurasi peta hasil klasifikasi habitat perairan dangkal antara citra SPOT 6, Sentinel 2A, dan Landsat 8 menggunakan algoritma klasifikasi support vector machine. Lokasi penelitian terletak di Kepulauan Wakatobi, meliputi 2 lokasi yaitu Pulau Kapota dan Pulau Kompoone. Pengambilan data in-situ dilaksanakan pada tanggal 7-11 Juli 2019. Sebanyak 347 ground truth dan foto transek hasil sampling di lapangan telah dianalisis menggunakan coral point count with excel extension (CPCe). Skema klasifikasi yang dihasilkan yaitu 8 kelas habitat bentik, selanjutnya dilakukan klasifikasi dengan mengkelaskan kembali menjadi 6 dan 5 kelas. Hasil yang diperoleh pada citra SPOT-6 untuk semua kelas habitat perairan dangkal yang digunakan memiliki overall accuracy yang lebih besar. Perbedaan ukuran piksel (resolusi spasial) dan jumlah skema klasifikasi sangat memengaruhi hasil akurasi.

Keberadaan ikan terumbu tentunya erat kaitannya dengan keberadaan terumbu karang karena ekosistem tersebut merupakan habitat bagi ikan karang. Terumbu karang merupakan ekosistem yang banyak terdapat di pulau-pulau kecil di daerah tropis termasuk Kepulauan Seribu. Kepulauan Seribu adalah sekelompok 110 pulau yang terletak di lepas pantai Jakarta dan hingga 80 kilometer sebelah utara Laut Jawa. Dalam studi ini, kami meneliti distribusi spesies dan keanekaragaman spesies ikan terumbu pada dua lokasi yaitu Pulau Untung Jawa dan Pulau Harapan yang berbeda jarak di Teluk Jakarta menggunakan analisis metabarcoding DNA lingkungan (eDNA). Sebanyak 4 liter sampel air laut dikoleksi pada kedalaman 8-9 meter per lokasi lalu dilakukan analisis menggunakan primer spesifik (MiFish U) dengan marka 12s rRNA. Secara keseluruhan, kekayaan spesies yang lebih tinggi ditemukan di Pulau Harapan (52 spesies) diikuti oleh Pulau Untung Jawa (11 spesies). Indeks Shanon-Wiener juga menunjukkan bahwa Pulau Harapan memiliki keanekaragaman ikan terumbu yang lebih tinggi berdasarkan tiga tingkatan taksonomi (famili, genus, dan spesies). Hanya ada lima spesies ikan terumbu mutual yang ditemukan di dua lokasi tersebut, yakni Atherinomorus aetholepis, Auxis thazard, Cephalopholis sexmaculata, Epinephelus chlorostigma, dan Plectropomus areolatus. Hasil temuan dalam penelitian ini sejalan dengan perbedaan antropogenik dimana Pulau Untung Jawa lebih dekat dengan Teluk Jakarta dibandingkan dengan Pulau Harapan yang letaknya relatif jauh dari Teluk Jakarta.

There are many species of macroalga grow in marine ecosystem and potentially as raw material for bioethanol resource. Bioethanol is a conversion result of carbohydrate, one of macroalgae biomass content. The exploration of macroalgae require information about growth rate ability to determine availability in the nature. This research analyze growth rate and carbohydrate content of marine macroalga Gelidium latifolium on cultivation using varied injection of carbon dioxide and aeration. The treatments were control (K), 2000 cc CO2 injection and aeration (P1), 3000 cc CO2 injection and aeration (P2), 2000 cc CO2 injection without aeration (P3), and 3000 cc CO2 injection without aeration (P4). Samples weight were 3 gram in early cultivation on laboratorium scale for 42 days observation. The results showed that the daily growth rate Gelidium latifolium during the study ranged from 0.02-1.06%. The highest daily growth rate was 1.06±0.14% (P2). Carbohydrate yield was 18.23% in early cultivation then 19.40% (K and P2), 20.40% (P1), 16.87% (K3), and 16.40% (P4) after cultivation. The high of carbohydrates value may not guarantee the sustainable Gelidium latifolium biomass utilization as raw material for bioethanol production because of the low growth rate, thus it is necessary to modified and encourage cultivation method effectively. Keywords: CO2 injection, growth rate, carbohydrate, macroalgae, Gelidium latifolium
