Abstract

Indonesia has a wide variety of fish resources and one of them is yellowfin tuna. Tuna in Palabuhanratu is caught by Tonda and swamp tuna. Tuna is an export commodity that causes an increase in catches and requires proper management of fish resources. One of the information needed in fisheries management is the relationship between weight-length and fish condition factors. The purpose of this study is to determine growth pattern and factors of yellowfin tuna conditions landed at Palabuhanratu Fishing Port. The study was conducted in Palabuhanratu from September 2021 to January 2022. Data collection was carried out at the fish landing site at Palabuhanratu Fishing Port. The data collected in this study consisted of primary data and secondary data. Primary data consist of data on the length and weight of the fish. As many as 200 yellowfin tuna was measured their total length and weight. The total lengths of the measured tuna ranged from 30.9 - 101.9 cm. The growth pattern model analysis showed b value of 2.7. This indicates that yellowfin tuna in the study area had a negative allometric growth pattern (b<3), which explains that the length gained was faster than the weight gained. Tthe condition factor of the yellowfin tuna fish ranged from 0.70 – 1.54, with an average of 1.0. The condition factor is influenced by the availability of food because Indian Ocean is available with sufficient food because the Indian Ocean is famous for its upwelling area.

Abstract

The beach is a location of the largest marine debris discovery because of the dynamics of the oceanography which is in direct contact with the land. Not a few beaches are close to the river and are vulnerable to being affected by domestic or household waste that comes from river flows. Palabuhanratu Bay is one of the tourist areas affected by waste input from various community activities on the land. Thus, it is necessary to discuss the identification and analysis of marine debris pollution in Palabuhanratu Bay, especially those from the Cimandiri River. The purpose of this study was to identify the distribution of waste types based on full moon and new moon conditions in Palabuhanratu Bay, Sukabumi, West Java. Sampling of marine debris data uses the line transect method and then garbage collection is carried out when the waste has accumulated. The collected waste is then cleaned, sorted and collected by category and then recorded on the marine debris sampling sheet. The types of waste observed included seven categories. The results showed that the waste generation during the full moon was 927 items, while in the new moon was 2,099 items. The density of waste at the research site was 1.85 items/m² (full moon) and 4.20 items/m² (new moon). The types of waste that are mostly found during the full moon and new moon are plastic waste in the amount of 16.87 to 47.08% and other types of waste (wood) is 38.75 to 73.29%.

Abstract

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.

Abstract

Salah satu komoditas penting perikanan tangkap di Sulawesi Tenggara, khususnya perikanan skala kecil adalah rajungan dengan menggunakan alat tangkap bubu. Usaha penangkapan dikatakan berhasil apabila mendapatkan keuntungan yang maksimal bagi pelaku usahanya. Penggunaan jenis umpan yang berbeda pada alat tangkap bubu menghasilkan hasil tangkapan yang berbeda. Tujuan penelitian ini adalah untuk menganalisa aspek finansial yang mencakup biaya, pendapatan, keuntungan, dan tingkat kelayakan finansial usaha penangkapan rajungan menggunakan umpan berbeda, yaitu ikan peperek dan ikan teri. Metode yang digunakan dalam penelitian ini adalah metode survei yaitu dengan cara peninjauan, pengamatan serta pengambilan data informasi secara langsung di lapangan. Hasil penelitian menunjukkan bahwa biaya tidak tetap yang dikeluarkan setiap tahunnya memiliki jumlah yang lebih besar dibandingkan dengan biaya tetap. Penerimaan terbesar usaha penangkapan rajungan adalah dengan menggunakan umpan ikan peperek dengan keuntungan yang didapat sudah dapat menutupi biaya-biaya yang dikeluarkan. Usaha penangkapan rajungan menggunakan ikan peperek dikatakan layak dan menguntungkan yang terlihat dari nilai NPV, IRR, dan B/C Ratio dengan pengembalian modal masuk kedalam kategori pengembalian modal sedang. Sedangkan dengan menggunakan umpan ikan teri mengalami kerugian, dimana penerimaan yang didapat tidak dapat menutupi biaya-biaya yang dikeluarkan.

Abstract

Coral reefs at the Kapoposang’s Water Tourism Park (TWP) Spermonde Island have significant ecological and economical functions but prone to damage and even death. The proneness may occur by the effect of domestic activities or natural disaster. This study aimed to determine the distribution of biological (chlorophyll), chemical (nutrients included nitrate and phosphate) factors in ocean surface water, and to analyze the relationship of biological and chemical factors within coral bleaching event at TWP Kapoposang of Makassar Strait Spermonde. Primary and secondary data carried out during 2000-2020, and data analysis conducted on February to April 2021.The study used time-series data of the Indonesian monsoonal seasons for the last 18-years and Landsat satellite imagery data for coral mapping in 2000, 2005, 2015, and 2020. The results showed that the nutrients distribution tend to horizontally autoctonous and chlorophyll was varying within monsoonal seasons. Finally, nutrient and chlorophyll may be correlated with coral bleaching event at TWP Kapoposang of Spermonde Makassar Strait, respectively.
