Shrimp is a fishery product that has high economic value and is experiencing ecological pressure due to habitat destruction. This study aims to determine the level of presence of shrimp species and shrimp species that dominate in the Mangrove Ecosystem Area of Gampong Alue Naga, Syiah Kuala District, Banda Aceh City. This study uses an exploratory survey method with purposive sampling technique. The tool used to catch shrimp is Pintur. Observation stations are determined based on water conditions, namely station I is in the middle of the brackish ecosystem, station 2 is close to the coast, station 3 is in a watershed area. The parameters measured in this study consisted of biotic parameters which included the presence and number of shrimp species that dominated and abiotic parameters consisted of water environmental conditions, namely water temperature, salinity, pH. Data analysis was carried out using the Attendance Rate formula and Simpson's Dominance formula. The results of the analysis showed that the species that had the highest level of presence was Jerbung Shrimp (Penaeus merguiensis de Man) with a frequency of presence of 74.07%, while the lowest found was Pistol Shrimp (Alpheus microrhynchus de Man) with an attendance frequency of 29.63%. The dominance values ranged from 0.04 – 0.17 where the lowest dominance was Pistol Shrimp (Alpheus microrhynchus de Man) and the highest was Jerbung Shrimp (Penaeus merguiensis de Man). In conclusion, the high value of the presence of the jerbung shrimp species (Penaeus merguiensis de Man) indicates that the adaptation value and range of this species is very wide.

The IUCN Redlist has included the double jowls cassowary in the vulnerable conservation status since 1994, so it is necessary to do ex situ conservation. Taman Safari Gurun Putih Lestari is one of the ex situ conservation areas in Aceh. The success of captive activities is influenced by several aspects, one of which is the provision of the type of feed. Feeding is very important in fulfilling animal nutrition for growth. The purpose of the research was to determine the level of feed palatability and the type of feed preferred by double jowls cassowary in Taman Safari Gurun Putih Lestari, Aceh Besar. The approaches used in this research are quantitative and qualitative approach. The method used is direct observation. The results of this study were the double jowls cassowary in cage I consumed 96.75% of banana, 93.32% of papaya, and 72.07% of cucumber. While the double jowls cassowary in cage II consumed 97.46% of banana, 92.89% of papaya, and 63.53% of cucumber.. The level of sweetness of the three types of feed has a different level of sweetness, namely banana very sweet with a sucrose amount of 12.1°Brix, papaya sweet with an 8.3°Brix amount of sucrose, and slightly sweet cucumber with a sucrose amount of 2.9°Brix. The conclusion of this research are the level of feed palatability of the double jowls cassowary belongs to the category of high palatability class and the most preferred type of feed is banana because of its sweet taste and soft texture.Keywords: feed, palatability, double jowls cassowaryIUCN Redlist memasukkan burung kasuari gelambir ganda dalam status konservasi rentan (vulnerable) sejak tahun 1994, sehingga perlu dilakukan konservasi secara ex situ. Taman Safari Gurun Putih Lestari merupakan salah satu konservasi ex situ di Aceh. Keberhasilan kegiatan penangkaran dipengaruhi oleh beberapa aspek salah satunya adalah pemberian jenis pakan. Pemberian pakan sangat penting dilakukan untuk pemenuhan gizi satwa bagi pertumbuhan. Tujuan dilakukan penelitian yaitu untuk mengetahui tingkat palatabilitas pakan dan jenis pakan yang disukai burung kasuari gelambir ganda di Taman Safari Gurun Putih Lestari, Aceh Besar. Pendekatan yang digunakan pada penelitian ini berupa pendekatan kuantitatif dan kualitatif. Metode yang digunakan adalah direct observation. Hasil dari penelitian ini adalah pisang bertekstur lunak, pepaya bertekstur lunak-berair, dan mentimun bertekstur keras-berair serta ketiga jenis pakan memiliki tipe buah sejati tunggal atau buah buni. Tingkat kemanisan daripada ketiga jenis pakan memiliki tingkat kemanisan yang berbeda yaitu pisang sangat manis dengan jumlah sukrosa 12,1, pepaya rasanya manis dengan jumlah sukrosa 8,3, dan mentimun agak manis dengan jumlah sukrosa 2,9. Simpulan dari penelitian ini adalah jenis pakan yang paling disukai yaitu pisang karena rasanya yang manis dan bertekstur lunak.Kata kunci: pakan, palatabilitas, burung kasuari gelambir ganda
