Abstract

This research was conducted from July to September 2023, with the aim of analyzing the relationship between oceanographic parameters and yellowfin tuna catch. The use of experimental fishing method with regression analysis and geographic information system is expected to answer the research objectives. Based on the results of the study, it was found that simultaneously oceanographic conditions have a significant effect on the catch of yellowfin tuna in Ternate Island waters with a calculated F value of 12,449 and a significance of 0.000, then with the backward method it was found that individually only sea surface temperature and chlorophyll-a concentration parameters were closely related to yellowfin tuna catches with a coefficient of determination (r2) value of 0.581 and 0.461, respectively. It is necessary to conduct further research with different fishing locations in order to determine the potential of fisheries, especially yellowfin tuna.

Abstract

Kelurahan Tobololo di Kota Ternate merupakan salah satu kawasan pesisir yang memiliki potensi penting sebagai habitat peneluran penyu. Namun, aktivitas masyarakat pesisir dan rendahnya kesadaran lingkungan berpotensi mengancam kelestarian spesies tersebut. Kegiatan pengabdian ini bertujuan untuk meningkatkan pemahaman dan kepedulian masyarakat setempat terhadap pentingnya konservasi penyu sebagai bagian dari ekosistem laut yang berkelanjutan, yang dilaksanakan pada bulan Maret 2024. Metode yang digunakan adalah sosialisasi interaktif melalui penyuluhan, diskusi kelompok, serta pemutaran media edukatif yang melibatkan berbagai unsur masyarakat, termasuk nelayan, pelajar, mahasiswa dan tokoh lokal. Pada kegiatan ini juga dilengkapi diberikan materi dengan cara pembagian materi edukasi cetak kepada peserta dan penguatan pesan konservasi melalui media sosial lokal. Hasil dari kegiatan menunjukkan adanya peningkatan pemahaman peserta mengenai siklus hidup penyu, ancaman terhadap kelestariannya, serta tindakan sederhana yang dapat dilakukan oleh masyarakat untuk mendukung upaya konservasi. Kegiatan ini diharapkan menjadi langkah awal pembentukan jejaring konservasi berbasis komunitas dan berkontribusi pada tujuan pembangunan berkelanjutan (SDGs), khususnya pada poin 14 mengenai ekosistem laut. Kolaborasi antara akademisi dan masyarakat lokal menjadi strategi penting dalam mendorong konservasi berbasis partisipatif yang berkelanjutan.

Abstract

Maitara Village is a coastal area with abundant fisheries potential, especially tuna (Euthynnus affinis). However, its utilization is not optimal because it is still limited to fresh consumption and traditional processing, resulting in low economic value. On the other hand, household waste such as leftover rice is also still not optimally utilized. This is an opportunity in developing innovative food products based on local potential. This service activity aims to improve skills and community empowerment through training in making tuna rice crackers as an alternative to diversifying processed fisheries. The methods used include counseling, hands-on demonstration, and practice of product making by participants, who mostly consist of housewives, which was carried out on Maitara Island, Maitara Village, North Tidore Subdistrict, Tidore Islands City in July 2025. The results showed a significant increase in participants' knowledge and skills in processing local raw materials into valuable products. This activity also encourages changes in the mindset of the community about the importance of innovation, household waste management, and family economic empowerment. In conclusion, this training successfully provided an applicable and sustainable solution in developing local potential while reducing waste, as well as opening new entrepreneurial opportunities for the people of Maitara Village

Abstract

The waters of North Maluku, abundant in nutrients and ocean currents, provide an ideal habitat for yellowfin tuna (Thunnus albacares), indicating a healthy marine ecosystem. Tuna, an oceanic pelagic species that migrates with ocean currents, is affected by sea surface temperature (SST) and chlorophyll-a plays an important role in determining yellowfin tuna fishing grounds. This study aims to analyze the spatial and temporal distribution of SST and chlorophyll-a concentration in North Maluku waters and analyze the relationship between SST, chlorophyll-a, and tuna catches. The present study employed both descriptive and quantitative analysis methods to examine the relationship between sea surface temperature, chlorophyll-a, and yellowfin tuna catch. The result shows that the temporal fluctuations in the highest recorded SST were seen in the 2021 transitional season, and the lowest in the 2019 East season. Chlorophyll-a concentrations also showed fluctuations, with the highest value recorded in the 2019 East season and the lowest in the 2020 second transitional season. There is an inverse correlation between SST and chlorophyll-a, with low SST tending to be accompanied by high chlorophyll-a concentrations. The decline in chlorophyll-a concentration can be attributed to various factors, including nutrient availability, sunlight intensity, and water temperature. About 17.48% of the catch of yellowfin tuna (Thunnus albacares) in North Maluku waters is influenced by SST and chlorophyll-a while the rest is influenced by other factors. This indicates that other factors play an important role in determining the catch of yellowfin tuna in North Maluku waters.
