Abstract

Rajungan (Portunus pelagicus) merupakan salah satu komoditas perikanan yang memiliki nilai ekonomis penting yang ditangkap dengan alat tangkap pasif, seperti bubu lipat. Penggunaan celah pelolosan pada bubu diharapkan mampu memenuhi ukuran rajungan yang diperbolehkan untuk ditangkap sebagaimana yang tertulis pada Peraturan Menteri Kelautan dan Perikanan 12/2020 (lebar karapas >10 cm). Tujuan dari penelitian ini adalah untuk mengetahui ukuran celah pelolosan yang sesuai untuk meloloskan rajungan dengan lebar karapas 10 cm serta mampu menahan rajungan dengan lebar karapas >10 cm. Sebanyak 30 ekor rajungan dengan lebar karapas 9-10,8 cm diuji cobakan terhadap tiga ukuran celah pelolosan yang berbeda (4,6 x 2,6 cm; 5 x 3 cm; dan 7 x 2,5 cm), dengan tiga kali ulangan. Uji coba dilaksanakan di laboratorium pada bulan Maret 2020. Hasil penelitian menunjukkan bahwa tidak ada perbedaan tingkat pelolosan rajungan pada ketiga ukuran celah pelolosan. Meski demikian, ukuran 4,6 x 2,6 cm diyakini merupakan ukuran yang paling efektif karena mampu meloloskan rajungan dengan lebar karapas 10 cm (46,9%), serta paling bagus dalam menahan rajungan dengan lebar karapas >10 cm tetap berada di dalam bubu. Percobaan lapang terhadap ukuran celah pelolosan ini pada beberapa perairan diperlukan untuk mengkonfirmasi penggunaannya pada perikanan rajungan.The blue swimming crab (Portunus pelagicus, BSC) is one of fishery commodities caught by passive gears, such as collapsible traps. The use of escape-vent on traps was supposed to comply with the legal size of BSC’s catch declared in the Ministerial Decree 12/2020 (i.e. >10 cm of carapace width). To determine an appropriate escape-vent size which is able to release BSC of 10 cm Carapace Width (CW) and to retain BSC of > 10 cm CW, 30 samples of BSC were tested on three different sizes of escape-vent (4.6 x 2.6 cm; 5 x 3 cm; and 7 x 2.5 cm) with three replications of each size. The results show that there was no significant difference of BSC’s escape rate among the escape-vent sizes. However, the size of 4.6 x 2.6 cm was assumed as the most effective escape-vent as it could release BSC of 10 cm CW (46.9%), and best to retain BSC of >10 cm CW inside the trap compared to other sizes. Field investigation might be needed to confirm the effect of the appropriate escape-vent size of collapsible trap on BSC fishery.

Abstract

Terjadinya penurunan produktivitas perikanan tuna di Perairan Selatan Jawa salah satunya disebabkan oleh adanya kondisi tangkap lebih yang terjadi akibat ketidaktersediaannya informasi geografis akurat terkait jumlah dan jenis spesies. Pendekatan spasial keragaman habitat spesies mampu memberikan prediksi akurat tentang jenis dan jumlah spesies pada suatu daerah penangkapan. Penelitian ini bertujuan untuk menghasilkan peta klasterisasi spasial keragaman spesies tuna berdasarkan data hasil tangkapan tuna dan data lokasi penangkapan di Perairan Selatan Jawa yang diperoleh dari kapal rawai tuna yang menangkap ikan di Samudera Hindia dan mendaratkan  tangkapannya di Pelabuhan Perikanan Samudera (PPS) Benoa pada bulan September-November 2019 dengan menggunakan beberapa analisis yaitu: (1) analisis keragaman spesies (Shannon-wiener index dan Menhinick index) dan analisis klasterisasi spasial (ward-hierarchical clustering dengan bootstrapped p-value). Berdasarkan kedua hasil analisis tersebut diperoleh tiga klaster pola sebaran daerah penangkapan tuna di Perairan Selatan Jawa yaitu: (1) klaster yang didominasi oleh spesies Thunnus albacares, (2) klaster yang didominasi oleh Thunnus obessus, dan (3) klaster dengan jumlah spesies tuna yang berimbang. Informasi mengenai ketiga klaster daerah penangkapan ini selanjutnya dapat digunakan sebagai rujukan penentuan pengelolaan perikanan tuna dan upaya pembatasan kapasitas penangkapan khususnya pada spesies tuna yang mengalami penurunan stok.

Abstract

This community service activity aims to improve the efficiency and competitiveness of Small, Micro, and Medium Enterprises (SMEs) of fish crackers in Pangkahkulon Village, Ujung Pangkah District, Gresik Regency through the introduction of appropriate technology or “Teknologi Tepat Guna” (TTG) in the form of an automatic cracker dough cutting machine. The problem experienced by community service partners is that the thickness of the crackers is not uniform and requires a long cutting time. Through this community service program, partners are provided with automatic cracker cutting machines. In contrast to the many different cutting machines on the market, this machine can directly cut 4-6 pieces at once in one cut, thus producing more slices and saving production time. The results of the practice of using this machine show that this machine can cut very well with a thickness of 1.5-4 mm according to the needs of partners. The thickness of the crackers produced is 2.5±0.3 mm and 2.9±0.3mm which is very in line with the partner's expectations, while if the partner cuts manually the slice thickness is 2.9±0.5 mm and 2.5±0.6mm. The use of this machine also cuts the time for cutting the cracker dough to less than half before, from 2 hours to 1 hour even with a larger amount of cracker dough. The application of appropriate technology can increase the quantity, quality and competitiveness of fish cracker SMEs in Pangkahkulon Village.

Abstract

Highlight Research This is the first study of microplastics in four beach sediments in the east part of Java Island. Bahak and Pesona Beach are connected to Java Sea (north part), while Tambak Rejo and Balekambang Beach are connected to Indian Ocean (south part). A higher microplastics were observed on the beaches of the north part compared to the south part. Local sources and oceanographic parameters of the beaches influence the presence of microplastics in the study areas. Abstract Microplastic pollution in beach sediments has been studied intensively worldwide, but there are limited studies in the beach areas of the eastern Java Island, Indonesia. This study aimed to identify the distribution of microplastic in four beaches in Indonesia: Bahak, Pesona, Tambakrejo, and Balekambang. The first two beaches are located in the north of Java Island and influenced by the east Java Sea, while the last two are located in the south and influenced by the Indian Ocean. Sediment samples were collected along the strandline inside the 1 í— 1 m transect quadrate in the top 5 cm using a stainless-steel shovel. Microplastic and granulometry analyses were conducted to obtain microplastic and sediment grain size data, respectively. Physical parameters of the beaches, such as wind, wave, and ocean current, were calculated using Copernicus and NASA (PODAAC), respectively. The total abundance of microplastic ranged from 54.7 ± 48.6 to 103.3 ± 4.7 particles kg-1 with the following descending order: Bahak > Pesona > Tambakrejo > Balekambang. Although there was no statistically significant difference in microplastic concentrations among the beaches, the beaches connected to the Java Sea accumulated more microplastics than the ones connected to the Indian Ocean. Fiber and blue were the dominating type and colors of microplastic. The results confirm that the distribution of microplastic is associated with the morphology of the beaches and the local source.
