Jakarta Bay is a blue swimming crab fishing area that must be managed by the DKI Jakarta Provincial Government for its sustainability. The DKI Jakarta Government must develop a good management plan based on data/information in the form of: (1) blue swimming crab habitat; (2) distribution of blue swimming crabs suitable for capture; (3) the value of the sustainable potential of Jakarta Bay; and (4) blue swimming crab fishing capacity. Currently, the condition of the data/information is unknown. This study aims to assess the availability and quality of data/information and assess its feasibility for developing a good management plan. Information on the availability and quality of data is collected through investigation of data/statistical information in various government/non-government agencies, field surveys, interviews with fishermen and various other sources. The scoring analysis was carried out for each type of data, consisting of: (A) data availability; (M) accessibilility of data; and (C) data adequacy. The scoring results show that the data for: developing a blue swimming crab habitat map, developing a map of the location and size of the captured blue swimming crab, estimating sustainable potential yield, and estimating the fishing capacity are 590, 500, 680, and 600, respectively. It was concluded that the DKI Jakarta Provincial Government could prepare a crab fishery management plan with several notes related to matters for which supporting data were not yet available.

Organisms such as Caulerpa racemosa seaweed, which play a pivotal role as primary producers in marine ecosystems, are particularly vulnerable to the deleterious effects of heavy metal exposure. Thus, comprehending the levels of heavy metals, in conjunction with parameters such as the bioconcentration factor (BCF) and geoaccumulation index (Igeo), pertaining to mercury (Hg) and lead (Pb) within the sediment and C. racemosa seaweed in Brondong, Lamongan is imperative for safeguarding the safety of seaweed-derived food products. Sampling of C. racemosa was conducted within traditional seawater ponds utilized for the cultivation of giant groupers, alongside other varieties of seaweed. The concentrations of heavy metals in various anatomical components of the seaweed (ramuli, stolons, rhizoids) and sediment were determined through spectrophotometric analysis utilizing Inductively Coupled Plasma Mass Spectrophotometer (ICP-MS). Laboratory analyses disclosed mercury (Hg) concentrations in C. racemosa ranging from 0.0212 ppm in rhizoids to 0.00437 ppm in ramuli, whereas tin (Sn) concentrations exhibited variability from 0.0392 ppm in rhizoids to 0.0390 ppm in ramuli. While mercury remained undetectable in sediment samples, moderate concentrations of tin were observed at approximately 2.10 ppm. The calculated bioconcentration factors (BCF) for tin in different segments of C. racemosa ranged from 0.0187 ppm to 0.0114 ppm, suggesting a low degree of bioaccumulation. Geoaccumulation index (Igeo) values spanned from -4.1876 to -4.2186 across distinct segments of C. racemosa, indicating marginal accumulation of heavy metals.

Teluk Jakarta merupakan kawasan penangkapan rajungan yang harus dikelola oleh Pemerintah Provinsi DKI Jakarta untuk kelestariannya. Pemerintah DKI Jakarta harus menyusun strategi pengelolaan yang baik berdasarkan data/informasi berupa: (1) habitat kepiting; (2) distribusi kepiting yang cocok untuk ditangkap; (3) nilai potensi berkelanjutan Teluk Jakarta; dan (4) kapasitas penangkapan kepiting. Saat ini kondisi data/informasi tersebut belum diketahui. Penelitian ini bertujuan untuk mengetahui ketersediaan dan kualitas data/informasi serta menilai kelayakannya sebagai dasar penyusunan rencana pengelolaan wilayah yang baik. Informasi keberadaan dan kualitas data dikumpulkan melalui penelusuran data/informasi statistik di berbagai instansi pemerintah/non pemerintah, survei lapangan, wawancara dengan nelayan dan berbagai sumber lainnya. Analisis skoring dilakukan untuk setiap jenis data, meliputi: (A) keberadaan data; (M) kemudahan akses data; dan (C) kecukupan data. Hasil skoring menunjukkan bahwa data kondisi pembuatan peta habitat rajungan, pembuatan peta lokasi dan ukuran rajungan yang ditangkap, pendugaan potensi lestari, dan pendugaan kapasitas penangkapan rajungan masing-masing adalah 590, 500, 680, dan 600. Disimpulkan bahwa Pemprov DKI Jakarta dapat menyusun rencana pengelolaan perikanan rajungan dengan beberapa catatan terkait hal-hal yang belum tersedia data pendukungnya. Kata kunci: kualitas data, rajungan, skoring, Teluk Jakarta
