Estimation of fishing grounds is one solution to facilitate time efficiency in fishing activities. Efforts are made to predict the fishing ground (fishing ground) through an approach to oceanographic physical conditions. The dynamics of skipjack fishing areas are influenced by oceanographic parameters such as sea surface temperature and chlorophyll-a concentration. Skipjack tuna (Katsuwonus pelamis) is the main type of fish caught in Indonesian waters. This study aims to analyze the dynamics of oceanographic conditions in the form of sea surface temperature and chlorophyll-a distribution, the relationship between skipjack fishing season and the dynamics of sea surface temperature distribution and chlorophyll-a distribution in WPP 573 waters 2016-2020 and predict skipjack fishing season.The catch results show that the average SST value obtained from the fishing grounds is 29.44 oC, the minimum value is 26.76 oC and the maximum value is 32.32 oC, while for the concentration of chlorophyll-a the average value obtained is 0.19 mg/ m3, the minimum value is 0.08 mg/m3 and the maximum value is 0.95 mg/m3. The average temperature and chlorophyll-a 2016-2020 that coincided with the high catch were 28.5oC and 0.23 mg/m3. The results of the MaxEnt model show that the evaluation of the model is in a good category, the percentage of SST contribution is higher than Chlorophyll-a, the probability index value for skipjack fish is around 0.5-0.8 and the results of the validation of fishing data are mostly widespread according to the results of the 2016-2020 MaxEnt model. The results also show that the east season, namely June, July and August, is a good fishing season for skipjack tuna, whereas skipjack catches decline in the west season, December, January and February.

The waters of Jakarta Bay are one of the waters that are influenced by several fresh water flows that enter from the DKI Jakarta area and its surroundings. Sediment that enters the waters of Jakarta Bay is produced by the activities of the people who live in the Jakarta area and its surroundings. This study aims to analyze the sedimentation and distribution of suspended solids in the Jakarta Bay estuary using an observational approach and spatial analysis. This study uses the Inverse Distance Weighting (IDW) interpolation method. The dominant distribution of sediment in Jakarta Bay is sand with a size ranging from 0.25 to 0.125 mm. TSS (Total Suspended Solids) levels in 11 estuaries in Jakarta Bay ranged from 21 to 150 mg/L in first period and 11 ˗ 259 mg/L in second period. Sedimentation rates that occurred in 11 Jakarta Bay estuaries ranged from 11.12 g/cm2/day to 619.5 g/cm2/day in period one and 10.96 g/cm2/day to 1232.06 g/cm2/day in the second period which is located in Muara Cilincing in both periods. There is a suitable relationship between the TSS value and the sedimentation rate. Estuary TSS values and sedimentation rates are influenced by seasons and anthropogenic activities that occur in the estuary such as reclamation.

In general, the focus of this study analyzes the strengthening of solidarity through social media networks in communities living in the Ciliwung River Basin. There are two objectives of this study, namely analyzing social media can strengthen the solidarity and the forms of solidarity that are built on the community affected by floods and landslides in the Ciliwung River Basin. This research was conducted in a community that resides in the Ciliwung River, Kedunghalang Village, North Bogor District, Bogor City. Theoretical analysis uses social media theory from VanDijk and the theory of solidarity from Durkheim. Data collection techniques were carried out by non-participant observation, and in-depth interviews. The data analysis technique was carried out by the Milles and Huberman analysis model among neigboarhoods (RT) and hamlet/groups of neighboarhoods (RW) level. The results of the study show that social media is able to strengthen community solidarity in the Ciliwung Riverbank, a disaster prone area. Solidarity built through social media are social relations, social norms and inter-household trust. Social relations built on social media networks at the level of individuals and groups are high. The form of built solidarity is mechanical solidarity that has a strong collective awareness, trust and mutual assistance. The novelty of this research shows that social media network is able to form social relations in strengthening solidarity.

AbstrakKegiatan perikanan tuna dengan penggunaan alat tangkap pole and line dan tonda berisiko menyebabkan kerentanan (risiko ekologi) yang dapat menganggu keberlanjutan stok tuna. Untuk itu dilakukan penelitian menilai kerentanan menjadi parameter risiko ekologi menggunakan pendekatan analisis productivity dan susceptability analysis (PSA) pada jenis ikan tuna sirip kuning (ukuran baby tuna), tongkol, lemadang, dan cakalang. Pengumpulan data biologi dan ekologi dari alat tangkap pole and line dilakukan di Flores dan pancing tonda di Pelabuhanratu. Selanjutnya, analisis laboratorium dilakukan pada Laboratorium Biologi Perikanan, Departemen Manajemen Sumberdaya Perairan, Fakultas Perikanan dan Ilmu Kelautan IPB. Hasil analisis produktivitas dan susceptabilitas alat pole and line untuk ikan baby tuna 1,42 dan ikan tongkol 1,98. Nilai ini menunjukkan tingkat kerentanan dan risiko ekologi pada ikan tongkol tergolong tinggi dan ikan baby tuna masih rendah. Analisis PSA dari alat pancing tonda pada ikan baby tuna diperoleh sebesar 2,34; ikan lemadang sebesar 2,34; dan ikan cakalang 2,18. Nilai ini menunjukkan bahwa kerentanan tinggi dan risiko ekologi pada ketiga jenis ikan tersebut juga tinggi karena penggunaan pancing tonda. Penggunaan alat tangkap pole and line serta pancing tonda pada perikanan tuna menyebabkan tingginya risiko pada ikan tuna sirip kuning (ukuran baby tuna), lemadang, cakalang, dan tongkol. AbstractTuna fishery activities using pole and line fishing gear and tonda have the risk of causing vulnerability (ecological risk) which can disrupt the sustainability of tuna stocks. For this reason, a study was conducted to assess vulnerability which is a parameter of ecological risk using the productivity and susceptibility analysis (PSA) approach to the fish’s species are albacares (baby tuna), mackerel, lemadang, and skipjack. Biological and ecological data collection from pole and line fishing gear was carried out in Flores and trolling and tonda in Pelabuhanratu. Furthermore, laboratory analysis was carried out at the fisheries biology laboratory, Department of Aquatic Resources Management, Faculty of Fisheries and Marine Sciences IPB. The results of productivity and susceptibility analysis of the pole and line for baby tuna and Euthynnus are 1.42 and 1.98. This value shows the level of vulnerability where the ecological risk of tuna is high and baby tuna also low. The PSA analysis of the tonda for baby tuna was 2.34; lemadang was 2.34; and skipjack was 2.18. This value indicates that the high vulnerability and ecological risk of the three species of fish are also high due to the use of tonda. The use of pole and line fishing gear and tonda lines in tuna fisheries causes a high risk for albacares (baby tuna), mackerel, lemadang, and skipjack.

ABSTRAKKondisi habitat dan eksosistem mangrove menjadi aspek penting dalam pengembangan usaha perikanan budidaya di wilayah pesisir. Penelitian bertujuan untuk mengkaji kondisi habitat dan ekosistem mangrove berdasarkan kualitas perairan, tanah, dan vegetasi mangrove serta kondisi sosial ekonomi masyarakat. Penelitian dilakukan di empat desa Kecamatan Simpang Pesak Kabupaten Belitung Timur pada bulan April – November 2013. Hasil penelitian menunjukkan kualitas air seperti salinitas 28–30, suhu 27–36 oC, pH 7–7,5, kecerahan 50–70, TSS 11–85 mg/L dan kekeruhan 0,91–46,00 NTU, yang rata-rata tidak melebihi ambang batas baku mutu untuk tambak udang dan biota laut, sedangkan kualitas tanah yaitu tekstur tanah (liat berpasir), pH tanah 4,8–6,8 dan bahan organik tanah 9–13% juga menunjukkan nilai yang tidak lebih dari ambang batas yang ditentukan. Kajian lainnya yaitu kondisi mangrove dengan kisaran indeks nilai penting 0–300 menunjukkan mangrove yang berperan dalam ekosistem tersebut dan dalam status mutu baik yang didukung dengan kerapatan 460 pohon/hektar. Oleh karena itu, nilai kerapatan yang tinggi dapat mendukung kegiatan pengembangan tambak udang yaitu dengan konsep ramah lingkungan (silvofisheries). Selain secara ekologi, secara sosial masyarakat juga mendukung pengembangan budidaya tambak udang (wawancara) dengan menyediakan (sewa) lahan dan tidak mengabaikan kerusakan lingkungan yaitu tetap mempertahankan mangrove.ABSTRACTThis research discusses about conditions of habitats and mangrove ecosystems which become an important aspect to develop a good aquaculture in coastal areas. This study aims to analyze the condition of the habitat and mangrove ecosystem based on the quality of water, soil, vegetation of mangroves, and socio-economic conditions of the social community. The study was conducted in four villages in Simpang Pesak, East Belitung Regency from April to November 2013. The results showed the indicator for water quality such as salinity 28-30, temperature 27-36 oC, pH 7-7.5, visibility 50-70, TSS 11-85 mg/L and turbidity 0.91-46.00 NTU, are on average rate so it does not exceed the threshold quality standards for shrimp and marine life. Besides, the quality of the soil, which is indicated by the soil texture (sandy clay), soil pH 4.8-6.8 and soil organic matter 9-13% also showed that it was not exceed a specified threshold too. Advance studies represent mangrove condition with important value index range from 28.30-69.94 showed that mangrove hold an important role in these ecosystem and in good quality supported by the density of 460 trees/ha. Therefore, the value of high density can support the development of shrimp farming that have an environmentally friendly concepts (silvofisheries). Social community can also supports the development of aquaculture shrimp. Interview results showed community provides (lease) of land and try to preserve the mangrove condition to protect it from the environmental damage.
