Abstract

Tabam waters are waters in Ternate City where the average population works as fishermen using gillnet fishing gear with the target fish being tuna (Eutynnus affinis) locally called Tongkol. Fishing activities in this area are generally carried out around FADs. Fishing that is carried out on an increasing basis and accompanied by an increase in gillnet fishing gear can endanger the sustainability of mackarel tuna/ tuna fish/komo tuna. Therefore, to maintain the sustainability of tuna fish resources in Tabam waters, an assessment of the biological status is needed which includes the structure of length, weight, circumference, growth patterns, and age groups. Establish guidelines for fishermen on the appropriate size of tuna to be harvested in order to preserve the sustainability of the tuna population. This research was conducted in December 2018-March 2019, using a sample size of 200 fish, using a survey method. The survey was conducted by examining the technical characteristics of gillnet fishing gear, FAD aids, and tuna catches. The results showed that the average fish caught was gilled with an isometric growth form and the average age group of tuna fish was around 21.7 cm, 17.2 cm, 18.9 cm, and 21.0 cm.Keywords:GillnetFADSAsessingKomoTunaTabam

Abstract

Climate change is a global challenge affecting the sustainability of coastal and small island ecosystems. Tanakeke Island in Takalar Regency, South Sulawesi, is an area vulnerable to the impacts of climate change, such as sea level rise, coastal erosion, mangrove ecosystem degradation, and declining fisheries yields. This study aims to analyze the impacts of climate change on the coastal ecosystem of Tanakeke Island using qualitative and quantitative descriptive approaches. Data were obtained through field observations, biophysical condition measurements, community interviews, and literature studies. The results indicate significant damage to mangrove forests, increased coastal erosion of up to 2 meters per year, and a decline in marine biodiversity. Local communities are experiencing impacts in the form of reduced fish catches and increased socioeconomic vulnerability. In conclusion, Tanakeke Island requires ecosystem-based adaptation strategies and strengthening community capacity to cope with climate change.

Abstract

Penelitian ini bertujuan untuk mengetahui kandungan metabolik sekunder ekstrak kunyit putih (Curcuma petiolata) dan kunyit (Curcuma longa) serta efektifitas dalam mematikan larva Anopheles sp. Metode yang digunakan adalah true eksperimen dengan rancangan eksperimen sederhana.Hasil penelitian diperoleh bahwa metabolit sekunder yang terkandung pada kunyit kuning (Curcuma longa diantaranya adalah flavanoid, terpenoid, dan fenolik, sedangkan Metabolit sekonder yang terkandung pada kunyit kuning yaitu alkaloid, saponin, dan senyawa Fenolik. Komponen bioaktif pada ekstrak kunyit putih (Curcuma petiolata) dan kunyit kuning (Curcuma longa) dapat membunuh larva nyamuk Anopheles sp. sehingga dapat dipertimbangkan berpotensi sebagai larvasida alami. Dimana larva uji pada ekstrak kunyit kuning (Curcuma longa) mengalam 100% kematian dalam waktu 1 jam pada kosentrasi 5% v/v dan kematian larva uji ekstrak kunyit putih (Curcuma petiolata) sebanyak 100% kematian dalam waktu 2 jam pada konsentrasi 80% v/v. Disimpulkan bahwa ekstrak Curcuma longa dan Curcuma petiolate memiliki pengaruh terhadap kematian larva Anopheles sp. dan dapat dijadikan sebagai pestisida alami dalam membunuh larva Anopheles sp
