Tuna is one of the mainstay commodities of South Sulawesi Province. The use of ink attractants to attract or lure Tuna, especially those made from non-food grade ingredients (can not be consumed) is increasingly widespread, but has the potential to pollute the environment. This study aims to compare the number of catches (volume) between tuna fishing rods with attractants made from screen printing ink (non food grade) with ink atractant made from food coloring. The experimental method used in this study was to collect data on the number of catches () of the two types of treatment on the tuna fishing rod at the fishing location. Data on the number of catches collected was then analyzed using Variance Analysis (ANOVA) patterned randomized block design (RBD). The results showed that the number of catches of tuna fishing with non-food-grade ink attractants is more than tuna fishi`ng lines with food-grade ink attractants. The analysis showed that the calculated F value for the treatment was 43.587 and the group was 8.956, greater than the F table value at the real level of 95% which meant that there were differences between the two forms of treatment and the group. Non-food-grade ink has an adequate level of viscosity because it does not dissolve quickly in seawater so that it is thought to attract or attract more attention or vision of Tuna fish to more aggressively grab the bait compared to food-grade ink. The focus of future research is to improve the performance of fishing line with food-grade ink to be more environmentally friendly.

Penelitian ini bertujuan untuk membandingkan rasio dimensi utama KMN. Reski 01 dengan rasio dimensi utama kapal ikan static gear umumnya di Indonesia dan menentukan tipe bentuk lambung kapal KMN. Reski 01 dari gambaran bentuk gading terbesar. Metode studi kasus digunakan untuk mengetahui penyebab kapal ikan ini memerlukan alat stabilizer tambahan saat drifting. Identifikasi dimulai dari rasio dimensi utama dan tipe bentuk lambung kapal dari gambaran kelengkungan gading terbesar sebagai data primer. Data sekunder diperoleh dari hasil pengolahan data penelitian yang telah dilakukan Iskandar & Pujiati, 1995. Analisa data dilakukan menggunakan metode comparative numeric dan deskriptif dengan bantuan software coreldraw. Berdasarkan hasil analisa, rasio dimensi kapal KMN. Reski 01 yang terdiri dari perbandingan L/B, L/D, dan B/D, masih masuk dalam kisaran kapal ikan static gear di Indonesia. Akan tetapi walaupun nilai perbandingan dimensi L/B berada di kisaran modus, nilai L/D dan B/D berada di atas kisaran modus dan median. Kapal KMN. Reski 01 yang merupakan kapal ikan static gear memiliki tipe lambung round bottom. Tipe lambung kapal ikan seperti ini lebih umum digunakan pada kapal ikan yang mengoperasikan alat tangkap aktif dari pada kapal ikan static gear.

Tujuan penelitian ini adalah menguji perbedaan posisi koordinat dan jarak Google Earth Pro terhadap beberapa GPS kondisi statis (diam). Uji Perbedaan posisi koordinat dan jarak GPS Garmin 585 terhadap GPS Furuno GP32 Kondisi real time (jalan) dan Uji tampilan peta Google Earth Pro terhadap tampilan peta eletronik GPS Garmin 585 dan Peta Laut kertas. Metode yang di gunakan adalah observasi dimana peneliti mengadakan pengamatan secara langsung terhadap posisi lokasi koordinat suatu tempat. Data di analisis secara deskriptif dalam bentuk gambar dan tabel, untuk perhitungan nilai jarak di gunakan menu yang terdapat pada aplikasi Google Earth Pro. Hasil penelitian menunjukan bahwa titik koordinat dan tampilan berupa peta pada aplikasi Google Earth Pro kondisi statis (diam) dan off line dapat di aplikasikan untuk menentukan posisi suatu benda di permukaan laut, namun untuk kondisi kapal real time sulit untuk di aplikasikan di laut. GPS Garmin 585 kondisi statis dan real time akurasi koordinat lebih stabil dibandingkan dengan GPS Furuno GP 32. Uji akurasi beberapa alat navigasi GPS Garmin 585 pada berbagai tempat tidak ada masaalah dalam menentukan posisi koordinat suatu tempat, sedangkan peta eletroniknya itu sendiri yang berupa SD Card menunjukan adanya perbedaan tampilan masing-masing perangkat GPS Garmin 585.

Graphical Abstract Highlight Research Synthetic nets, widely used in aquaculture and marine fishing, experience reduced performance over time due to environmental exposure. The study analyzes the effectiveness of Toli shad gillnets based on their technical age using statistical and experimental methods. A strong negative correlation exists between technical age and both breaking strength (r = -0.972) and elongation (r = -0.92). Toli shad gillnets perform optimally within 2 to 3 years of use, with effectiveness declining by the fourth year as indicated by scores of 40–59, suggesting adequate performance but the need for targeted improvements. Medium-term maintenance should be performed annually throughout the net’s service life, up to a maximum of 7 years, while replacement is recommended starting in the 4 year to mitigate performance degradation. Abstract Synthetic nets have high elasticity and are widely used for both aquaculture and marine fishing. However, as their technical age increases, their performance declines due to wear, reduced breaking strength, and decreased elongation caused by continuous exposure to the marine environment. Monitoring the technical age of nets is crucial to maintaining the effectiveness of Toli shad gillnets, minimizing losses, and ensuring optimal catch yields. This study aims to examine the physical degradation of synthetic gillnets used in Toli shad (Tenualosa macrura) fisheries based on their technical age. This study utilized gillnets targeting toli shad (Tenualosa macrura), with varying technical ages (control net, 1-year, 2-year, and 3-year nets), all made from polyamide (PA) monofilament. The differences in net dimensions were attributed to variations in their service life. The method used is purposive sampling, analyzed using descriptive statistics, correlation analysis, a Completely Randomized Design (CRD), and effectiveness evaluation. The results show that the structure of Toli shad gillnets consists of mesh sizes of 77.82–99.60 mm, thread diameters of 0.34–0.53 mm, and knot heights of 1.52–2.28 mm. The relationship between technical age and breaking strength has a correlation coefficient (r) of -0.972, an R² of 0.94, and a regression equation of y = 9.85 - 1.31x. The LSD test indicates a significant difference in breaking strength across treatments. The correlation between technical age and elongation has an r-value of -0.92, an R² of 0.86, with the equation y = 20.11 - 0.34x. The LSD test shows that the control net has significantly different elongation compared to others, but nets aged 1, 2, and 3 years show no significant differences. The study concludes that Toli shad gillnets remain effective for up to 3–4 years, with an effectiveness value of ≥50%. The implications of this study contribute to the efficient management of fishing nets by informing maintenance and replacement strategies based on the technical age and mechanical degradation of the gear. These findings suggest the importance of integrating net lifespan into gear management to enhance catch performance and sustainability in small-scale fisheries.
