Abstract

 The aim of the study was to analyze the value of coastal local wisdom of the indigenous people of Jeflio Island for the development of mangrove ecotourism. In the research method used qualitative and quantitative approaches. Data analysis includes analysis of local wisdom values. Based on research, the Jeflio community has local wisdom in the form of calls for conservation known in the form of recommendations such as "Nani Mi Wawolom Ti Eges Gu" (the native language of the Moi tribe), Pamali (prohibition) in certain areas/areas, Sasi - Customs and ceremonies," barapen" as well as local handicrafts such as making senate/mats, woven bags, "bayayai", boats, oars and spears. Local Wisdom Through Advice “Nani Mi Wawolom Ti Eges Gu” comes from the language of the Moi tribe which means protecting nature together. Local wisdom, such as local skills, traditional ceremonies and local values, is a cultural tourism attraction that can be empowered by tourism managers as creative industries to develop mangrove ecotourism to attract tourists and support local community economic development. One of the improvements in existing facilities in the Jeflio Mangrove Ecotourism Area is a souvenir shop that can be used to sell local Jeflio community crafts. In order to maintain and maintain the infrastructure of the Jeflio Mangrove Ecotourism Area, local wisdom values such as mutual cooperation and togetherness are very much needed. There are still weaknesses in the use of local wisdom in Jeflio because local wisdom owned by the community has not been legitimized.

Abstract

Aplikasi fungisida Antracol dalam praktik budidaya pertanian berpotensi menimbulkan konsekuensi yang mengkhawatirkan bagi keseimbangan ekosistem aquatik, terutama terhadap biota perairan. Studi ini dirancang untuk mengevaluasi dampak variasi dosis Antracol terhadap tingkat survivabilitas ikan nila (Oreochromis niloticus) serta karakteristik parameter lingkungan perairan. Metodologi penelitian mengimplementasikan desain Rancangan Acak Lengkap (RAL) dengan mengaplikasikan 5 variasi tingkat konsentrasi (0,01; 0,1; 1; 10; 100 ppm) ditambah kelompok kontrol, dimana setiap perlakuan direplikasi sebanyak 2 kali. Temuan penelitian mengindikasikan terjadinya degradasi yang signifikan pada persentase kelangsungan hidup berbanding lurus dengan eskalasi konsentrasi Antracol, dengan persentase kematian puncak mencapai 85% pada aplikasi konsentrasi 100 ppm. Karakteristik parameter kualitas perairan mengalami transformasi yang substantial, meliputi reduksi kandungan oksigen terlarut hingga mencapai level 1,5 mg/L, variabilitas nilai pH dalam rentang 7,49-8,18, serta elevasi temperatur yang mencapai 30,5°C. Evaluasi statistik mengungkapkan adanya hubungan korelasi positif yang sangat kuat (r > 0,95) antara tingkat konsentrasi Antracol dengan persentase mortalitas, menunjukkan pola respon yang bersifat eksponensial. Hasil investigasi ini mengkonfirmasi bahwa Antracol memiliki potensi toksisitas yang substantial terhadap ikan nila bahkan ketika diaplikasikan dalam konsentrasi yang relatif rendah, sehingga menekankan urgensi implementasi sistem manajemen yang lebih rigorous dalam penggunaan fungisida di kawasan pertanian yang berdekatan dengan habitat perairan.
