Abstract

Ecotourism of the Gunung Pandan Natural Baths, which is located in Selamat Village, Tenggulun District, is one of the priority scales for tourism development in Aceh Tamiang Regency. The development of ecotourism is believed to be able to maintain the conservation of natural resources and improve the welfare of the surrounding community. This study aims to assess the feasibility of developing ecotourism at the Gunung Pandan Natural Baths. The assessment of potential tourism objects uses the Guidelines for Operation Areas for Natural Tourism Attractions (ADO-ODTWA) issued by the Director General of PHKA of the Ministry of Forestry in 2003. The results of the ADO-ODTWA analysis show that the Gunung Pandan Natural Baths as a conservation area are worthy of being developed as an ecotourism destination, with a recapitulation potential value index of 83.39%. Some criteria that need attention and improvement are accessibility and security. Improving the two components is a priority to develop the Gunung Pandan Natural Bath Ecotourism area into a leading ecotourism destination.

Abstract

Suhu faktor lingkungan yang dapat mempengaruhi kematian ikan bass pada fase embrio, karena embrio paling rentan terhadap perubahan stres karena embrio masih sensitif. Tujuannya adalah untuk melihat suhu yang optimal dan apakah perbedaan suhu dapat menyebabkan perubahan yang signifikan pada perkembangan embrio, kecepatan tetas, kecepatan tetas dan kelainan pada larva ikan bass. Metode yang digunakan adalah RAL dengan 4 perlakuan dan 3 ulangan yaitu S1 = 26 oC, S2 = 28 oC, S3 = 30 oC, dan S4 = 32 oC. Uji LSD 95% menunjukkan perkembangan embrio pada S4 (32 oC ) .C) menunjukkan tercepat di semua tahap perkembangan embrio, penetrasi tercepat ada di S4 (32 oC) selama 656,6 menit, penetrasi tertinggi pada S2 (28 oC) sebesar 95.258%, kelainan permanen terendah pada S1 (26 o C) sebesar 0%. Hasil penelitian menunjukkan bahwa perbedaan suhu media inkubasi memberikan pengaruh yang sangat nyata terhadap perkembangan embrio, kecepatan tetas, dan kelainan larva bass laut ( Lates calcarifer ).

Abstract

Vannamei shrimp (Litopenaeus vannamei) is a type of shrimp that is often cultivated. This study aims to identify ectoparasites and their prevalence in vannamei shrimp in the village of Pantai Gading, Kec. Secanggang Kab. Langkat. This research method is a survey method, where the observed ponds are 3 ponds and samples are taken as much as 5% of the stocking density of biota. Samples were taken randomly and then examined at the Laboratory of the Faculty of Agriculture, Universitas Samudra. Organs observed included carapace, gills, swimming legs, walking legs, and tail. Based on the identification results, three types of ectoparasites that infested were obtained, namely from the Phylum Protozoa including Zoothamnium sp., Epistylis sp. and Vorticella sp., with prevalence of 83.33%, 10% and 7.33%, respectively. The results of the observation of water quality parameters showed that the temperature ranged from 30.7 to 32.3 oC, pH 6.85-7.25, DO 2.6-3.6 mg/l, salinity 7-10 ppt, ammonia 0-0.01 ppm, nitrate 10-12 ppm, and nitrite 0-0.01 ppm. The highest prevalence of ectoparasites is Zoothamnium sp.Keywords: Ectoparasites; Identification; Prevalence; Vannamei Shrimp
