Abstract

Blue Swimming Crab (Portunus pelagicus, BSC) is one of the Indonesian important fisheries commodities often captured by traps. Under Decree No. 56/2016, the Ministry of Marine Affairs and Fisheries managed the BSC, with the standard size of BSC is >10cm of Carapace Width (CW) or >60 g of Weight (W), and non-berried or carried eggs for female. This study aims to determine BSC's crawling pattern toward the trap, design an escape vent on the trap, and assess catch of BSC using vented trap and non-vented trap. The video footage was used to examine crawling pattern of 30 BSCs on the laboratory. The study also includes field experiment by deploying twenty traps (10 vented traps and 10 non-vented traps) on the sea. The study obtained two crawling patterns of BSC, crawling forward and sideways with the most BSC crawled sideways. Design of escape vent was 4.6 cm length x 2.6 cm height. The BSCs captured in the vented traps have >10cm of CW, while 14% of BSCs in the non-vented traps have <10 cm of CW. The use of escape vent did not affect the catch (weight) of BSC in the trap.

Abstract

Degenerative diseases such as stroke and cancer arise due to oxidative stress by a large number of reactive oxygen species (ROS) in the body. Free radical scavenging (antioxidant) compounds are needed to neutralize the ROS. The natural antioxidant potential of mangrove species Sonneratia caseolaris has been widely explored. However, its extraction is usually carried out with polar solvents such as methanol. Besides being more toxic than ethanol, methanol can cause blindness and death when inhaled in large quantities. Additionally, Indonesia, as the country with the largest Muslim population, requires the use of halal products for food and cosmetics. This study aims to analyze the scavenging activities of S. caseolaris with methanol and distilled water as the polar solvents for extraction. Antioxidant activity was tested with the free radical assay method of DPPH (2,2-diphenyl-1-picrylhydrazyl radicals). The test results were calculated as the IC50 value, a concentration capable of reducing free radicals by 50%. The antioxidant activity test showed that the IC50 values of methanol and distilled water were 18.9 ppm and 36 ppm, respectively. Therefore, both are considered very strong antioxidants. It indicates that distilled water is an acceptable substitute for methanol in the extraction process. Keywords: antioxidant, extraction, mangrove, solvent, Sonneratia.

Abstract

Microplastic pollution has become a serious issue worldwide. Once it enters the environment, microplastics could accumulate in the water column and sediment. This study aimed to analyze the occurrence of microplastics in the beach sediments along the western coast of Situbondo, East Java. Sediment samples were collected in the strandline areas from seven different beaches that received the high impact of human activities. In the laboratory, sediment samples were oven-dried and weighed, density separation was performed using NaCl solution, degradation of organic matter was conducted using H2O2 30% and microplastic particles were identified using a microscope. In total, 1041 microplastic particles were retrieved from 21 sediment samples consisting of fiber (50 %), fragment (37 %), microbeads (11 %), and film (2 %). Microplastics found in this study consists of blue color (49 %), red (26 %), white (11 %), brown (7 %), and other colors such as yellow, black, green, and transparent with a percentage between 1?3 %. Microplastics with a size of < 300 µm dominate the result of this study. Microplastic abundances were found in the range of 204.52?492.50 particles/kg sediment sample. In each sampling location, the types of microplastic were found in a different pattern. Fiber and fragments were found in all sampling sites, while film and microbeads were found only in specific sites. This study showed that several factors, such as plastic sources and hydro-oceanography parameters, influenced the occurrence of microplastics in the sampling sites. In order to address microplastic pollution in the marine environment, plastic waste management strategies are required.Keywords: Fishing port, Mangrove, Marine Pollution, Plastics, Tourism

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan pendampingan dalam pengembangan dan analisis kelayakan usaha kerupuk ikan pada home industry Abizar di Desa Pangkahkulon Ujung Pangkah-Gresik dari berbagai aspek. Pendampingan dilakukan dengan beberapa kegiatan antara lain pengenalan dan pemberian bantuan alat produksi, pelatihan pemasaran, dan pelatihan pengelolaan keuangan. Sedangkan analisis kelayakan usaha ditinjau dari beberapa aspek yaitu aspek teknis produksi, manajemen, pemasaran, legalitas dan aspek keuangan. Hasil analisis menunjukkan bahwa UKM secara umum layak dijalankan dari berbagai aspek di atas. Dari aspek finansial yang menjadi indikator utama kelayakan usaha, terdapat profit ratio yang sangat besar, Net B/C ratio yang mencapai 5,05, Profitabilitas 40%, dan R/C Ratio 1,5 serta payback period kurang dari setengah. setahun, maka usaha ini layak untuk diusahakan dan dapat dilanjutkan. Berdasarkan studi kelayakan usaha juga dapat disimpulkan bahwa pendampingan usaha dengan memberikan bantuan alat produksi tidak memberikan beban keuangan baru bagi pengusaha tetapi justru meningkatkan efisiensi dan keuntungan usaha. Namun masih perlu pembenahan terutama dari aspek legalitas usaha karena UKM mitra belum memiliki legalitas sama sekali.

Abstract

Variabilitas Suhu Permukaan Laut (SPL) dan sebaran klorofil-a di Perairan Muncar (Selat Bali) sangat mempengaruhi hasil tangkapan ikan yang didaratkan di Pelabuhan Perikanan Pantai (PPP) Muncar. Informasi mengenai hal ini penting untuk kajian pendugaan dinamika penangkapan ikan melalui penginderaan jauh. Penelitian ini bertujuan untuk mengetahui variabilitas parameter oseanografi pada tahun 2018 hingga 2022, serta dinamika penangkapan ikan di Perairan Selat Bali, khususnya di PPP Muncar. Data yang digunakan dalam penelitian ini meliputi SPL dan klorofil-a dari satelit Aqua-MODIS level 3 dan data produksi ikan dari PPP Muncar selama 5 tahun. Hasil analisis menunjukkan fluktuasi SPL dan konsentrasi klorofil-a dengan keterkaitan erat antara keduanya. Selama periode tersebut, dinamika penangkapan ikan menunjukkan peningkatan produksi ikan lemuru dan layang pada tahun 2019, meskipun terjadi penurunan produksi pada tahun 2022 akibat peningkatan SPL yang berdampak pada stok ikan. Analisis hubungan antara anomali SPL dan klorofil-a menunjukkan bahwa konsentrasi klorofil-a meningkat saat SPL menurun dengan korelasi -0.378. Fenomena penurunan SPL di perairan Selat Bali menyebabkan adanya peningkatan nilai klorofil-a di perairan yang juga mendukung peningkatan pada hasil produksi ikan. Sedangkan peningkatan SPL yang berkontribusi pada menurunnya hasil produksi ikan. Pemahaman mengenai keterkaitan antara SPL dan klorofil-a dapat digunakan salah satu pertimbangan dalam merumuskan strategi pengelolaan sumber daya ikan yang lebih berkelanjutan, guna meningkatkan produksi perikanan di wilayah tersebut di masa depan.   Sea Surface Temperature (SST) variability and chlorophyll-a distribution in the Muncar Waters (Bali Strait) have been demonstrated to significantly impact the catch of fish landed at Muncar Fishing Port. This information is crucial for the study of estimating fishing dynamics through remote sensing. The present study aims to ascertain the variability of oceanographic parameters from 2018 to 2022, as well as the dynamics of fishing in the Bali Strait Waters, with a particular focus on the Muncar Fishing Port.The study utilizes data from the Aqua-MODIS satellite level 3, which includes SPL and chlorophyll-a measurements, along with fish production data from PPP Muncar over a five-year period. The analysis revealed fluctuations in SST and chlorophyll-a concentrations, with a close relationship between the two parameters. During the observed period, fishing dynamics exhibited an increase in Bali Sardinella and Indian Scad production in 2019, followed by a decrease in 2022, attributed to an increase in SPL, which impacted fish stocks. The analysis revealed a negative correlation between SPL and chlorophyll-a anomalies, with chlorophyll-a concentrations increasing as SPL decreased, as indicated by a correlation coefficient of -0.378. The observed phenomenon of decreasing SPL in the waters of the Bali Strait is concomitant with an increase in chlorophyll-a concentration, thereby supporting an increase in fish production. Conversely, an increase in SPL is associated with a decrease in fish production. A comprehensive understanding of the intricate relationship between SPL and chlorophyll-a can inform the development of more sustainable fish resource management strategies, with the ultimate goal of enhancing fisheries production in the region.

Abstract

AbstractFouling can be defined as undesired aggregation of living organism on float or submerged thing (ships, wharf, and the others off shore building). Fouling may effect on the function and maintenance of an object by lessen their lifetime, and evoked invasive species. TBT antifouling materials such as in paint widely used to prevent fouling organism, but this substance gave negative impact on the environment. It not only wipe out fouling organism but also other organism and some degree cause imposex. Therefore in 2008, the use of this antifouling was banned by International Maritime Organization. This research aiming to found potential marine natural product there are mangrove as antifouling. This research was conducted on September to December 2016. The experimental design for this research was using completely randomized design. Result shows that experimental the extract of Avicennia marina did not have significant impact on Perna viridis ability to bind onto subtrate. Nevertheless, A. marina had impact on P. Viridis byssus production. Lesser number and shorter length of byssus was yield from the treatment concentration compared to the control. This research indicated that Avicennia marina may has antifouling potential, but further study is needed. Keywords: Antifouling, Avicennia marina, Byssus, Perna viridis

Abstract

Mikroplastik merupakan bagian terkecil dari plastik yang berukuran 0,3 mm – >5 mm. Mikroplastik yang masuk ke lingkungan akan terakumulasi di perairan dan tidak mudah dihilangkan karena sifatnya yang persisten. Banyaknya kelimpahan mikroplastik sangat dipengaruhi oleh aktivitas dan sumber pencemarnya. Tujuan penelitian ini adalah untuk mengetahui kelimpahan dan jenis mikroplastik pada perairan di Banyuurip. Pengambilan sampel perairan dilakukan pada 5 lokasi yang memiliki aktivitas berbeda, yaitu tempat pelelangan ikan (TPI), mangrove, tambak, muara sungai, dan laut lepas. Pengambilan sampel perairan dilakukan sebanyak 3 kali pengulangan mengguakan plakton net dengan volume air tersaring sebanyak 15 L pada setiap stasiun. Idetifikasi mikroplastik menggunakan metode NOAA yang dibagi menjadi 4 tahapan, yaitu penyaringan sampel, pengeringan sampel, pemisahan zat organik dan identifikasi mikroplastik. Perbedaan kelimpahan jenis mikroplastik pada setiap lokasi dianalisis dengan mengukan ANOVA one way. Hasil kelimpahan total yang ditemukan sebesar 57,11 x 10² partikel/m³. Jenis mikroplastik yang ditemukan adalah fragment, fiber, dan film. Jenis mikroplastik yang paling banyak ditemukan pada perairan Banyuurip adalah jenis fragment. Hal ini dikarenakan sumber pencemaran mikroplastik jenis fragment lebih besar, yaitu berasal dari limbah rumah tangga dan kegiatan antropogenik. Kelimpahan jenis mikroplastik paling tinggi ditemukan pada mangrove sebesas 22,89 x 10² partikel/m³. Sementara itu, kelimpahan jenis mikroplastik pada lokasi tambak, muara sungai dan laut terbuka memiliki rentang nilai yang tidak jauh berbeda, yaitu 7,11– 8,89 x 10² partikel/m³. Hal ini diduga karena sampah lebih mudah terperangkap di akar-akar mangrove dan terakumulasi lebih banyak.

Abstract

Rajungan (portunus pelagicus) merupakan salah satu komoditas penting perikanan Indonesia. Pengetahuan tentang aspek biologi rajungan, termasuk hubungan antar ukuran bagian-bagian tubuhnya (morfometrik) dan sebaran lebar karapas serta beratnya, akan berguna sebagai salah satu informasi dalam pengelolaan rajungan. Penelitian ini bertujuan untuk mengetahui hubungan lebar karapas- berat rajungan, hubungan lebar-panjang-tinggi karapas, serta sebaran lebar dan berat rajungan. Metode yang digunakan adalah survei dengan pengambilan sample secara acak pada 2 (dua) titik pendaratan ikan di perairan utara Lamongan, khusunya kecamatan Paciran pada bulan Juli sampai September 2018. Hasil penelitian menunjukkan sifat pertumbuhan isometrik untuk rajungan betina dan allometrik positif untuk rajungan jantan. Selain itu, didapatkan hubungan linear positif dengan nilai a = 0,06 dan b = 0,45 untuk lebar-panjang karapas serta nilai a = 0,06 dan b = 0,25 untuk lebar-tinggi karapas. Rajungan betina paling banyak ditangkap pada lebar karapas 12-13 cm dan berat 100 g, sedangkan rajungan jantan sering ditangkap dengan lebar karapas 11 cm dan berat 80-90 g.  Masih adanya rajungan dibawah ukuran lebar karapas 10 cm yang tertangkap (lebar karapas diatas 10 cm adalah aturan rajungan yang boleh ditangkap sesuai dengan PER MEN KP 56/2016), maka informasi tentang hubungan lebar-panjang-tinggi rajungan dapat dijadikan masukan untuk melakukan modifikasi alat tangkap, misalnya mendesain ukuran celah pelolosan pada bubu, agar rajungan dengan lebar karapas dibawah 10 cm dapat keluar dari alat tangkap.
