Abstrak: Docosahexaenoic Acid (DHA) sangat dibutuhkan pada masa kehamilan dan laktasi untuk perkembangan otak janin (bayi), dan dapat dikonsumsi sebagai suplemen untuk anak-anak serta orang dewasa dalam bentuk kapsul lunak maupun produk emulsi cair. Formulasi produk emulsi suplemen minyak ikan mata tuna kaya DHA dan hidrolisat protein ikan kayu masih diperlukan terkait kendala stabilitas emulsi dan umur simpan. Penelitian ini bertujuan menentukan stabilitas dan umur simpan produk emulsi berbasis minyak ikan mata tuna dan hidrolisat protein ikan kayu. Penelitian meliputi produksi minyak ikan mata tuna, pembuatan hidrolisat protein ikan kayu dengan enzim papain 3.000 unit/g, pembuatan produk emulsi minyak ikan mata tuna dan hidrolisat protein ikan kayu, penyimpanan selama 14 hari, dan pendugaan umur simpan dengan metode Arrhenius pada suhu 40°C, 45°C, dan 50°C menggunakan titik kritis bilangan peroksida. Stabilitas emulsi menunjukkan adanya penurunan selama penyimpanan yang ditandai dengan peningkatan ukuran globula dari 1 µm menjadi 3 µm dan terjadi agregasi serta koalesensi pada penyimpanan hari ke 8 dan ke 10. Umur simpan melalui pendugaan Arrhenius menggunakan ordo nol dihasilkan lama penyimpanan 144 hari atau sekitar 4 bulan pada suhu 29°C., Docosahexaenoic Acid (DHA) is necessary during pregnancy and lactation for fetal brain development (infants), and can be consumed as a supplement for children and adults in the form of soft capsules or liquid emulsion products. The formulation of a DHA-rich tuna eye fish oil supplement emulsion product and katsuobushi protein hydrolyzate is still desired due to the constraints of emulsion stability and shelf life. This objective of this study were to determine the stability and shelf life of tuna eye fish oil-based emulsion products and katsuobushi protein hydrolyzate. The research included the production of tuna eye fish oil, manufacture of katsuobushi protein hydrolyzate with papain enzyme 3,000 units/g, manufacture of tuna eye fish oil emulsion and katsuobushi protein hydrolyzate, storage for 14 days, and estimation of shelf life using the Arrhenius method at 40° C, 45°C, and 50°C with the critical point of peroxide number. Emulsion stability showed a decrease during storage which was indicated by an increase in globule size from 1 m to 3 m and the aggregation and coalescence occurred on the 8th and 10th days of storage. Shelf life through Arrhenius estimation using zero order resulted in a storage period of 144 days or about 4 months at 29°C.

Judul: Stability of tuna eye oil emulsion product as a health supplement
Abstrak: Stunting merupakan gangguan pertumbuhan pada anak akibat pola makan yang buruk. Upaya pemerintah dalam menanggulangi stunting dengan memfokuskan pada 1.000 hari pertama kehidupan (HPK). Pemberian suplemen kesehatan yang memiliki kestabilan yang baik dengan kandungan gizi yang mencukupi angka kecukupan gizi (AKG) menjadi penting untuk dilakukan. Penelitian ini bertujuan menentukan stabilitas pada formulasi sediaan produk emulsi berbasis minyak mata tuna dan hidrolisat protein ikan. Metode yang digunakan dalam ekstrasi minyak dengan sentrifugal separation, pembuatan formulasi dengan penambahan hidrolisat protein ikan dan air jahe, dan pengujian stabilitas dengan cycling test. Parameter stabilitas produk emulsi setelah dilakukannya cycling test memiliki nilai pH produk 4,03±0,26–4,28±0,08, viskositas 1670±546–2400±347 cP, ukuran droplet 9,93–12,38 µm, DHA 235 mg, EPA 90 mg, protein 2.821 mg dalam 33,33 gram volume suplemen dengan takaran saji 3 kali sehari 1 sendok makan. Peptida yang teridentifikasi AIYK, Val-phe, VKF, Ile-leu-leu-ile, dan Val-leu serta bobot molekul 7,154 – 7,203 kDa., Stunting is a growth disorder in children due to poor diet. The government's efforts to tackle stunting focus on the first 1,000 days of life (HPK). The provision of health supplements that have good stability with adequate nutritional content is important to do. This study aimed to determine the stability of tuna eye oil-based and Fish protein hydrolyzate-based emulsion products. Emulsion product formulated with fish protein and ginger water. Centrifugal separation method used to extract the oil, and cycling test method used to measure the emulsion product stability. The stability parameter of the emulsion product after the cycling test had a product pH value of 4.03±0.26–4.28±0.08, viscosity 1670±546–2400±347 cP, droplet size 9.93–12.38 m, DHA 235 mg, EPA 90 mg, 2.821 mg protein in 33.33 grams of supplement volume with a serving size of 3 times a day 1 tablespoon. The identified peptides were AIYK, Val-phe, VKF, Ile-leu-leu-ile, and Val-leu and the molecular weight was 7.154 – 7.203 kDa.

Abstrak: Bare-throathed whistler is one of several wild birds in Kelimutu National Park (TNKL) that is believed to have correlation with Lio Community‟s belief. The estimation of Bare-throated whistler‟s population in Kelimutu National Park was about 186.41-1668.07 individual by the density about 0.0389-0.3481 ind/ha with the sex ratio 6.2:1 that spreaded on area with height of 1100 – 1600 masl. The characteristic of Bare-throated whistler‟s habitat is a natural forest with various canopy level, high plant species diversity and high density. The habitat characteristics related to the availability of food in the form of insects, cover, safety and a nesting site. Generally the most of Lio community knew the existence of Bare-throated whistler directly or from their parents‟ stories. The perceptions of Lio Community to the Bare-throated whistler‟s existence is generally support the conservation efforts. The perceptions construct the Lio Community‟s atitude that tend to be conservative to the existence of Bare-throated whistler. The attitude shown by their behavior that not cathing the Bare-throated whistler from the TNKL‟s area or the outside. The attitude have an important role to the existence of Bare-throated whistler in Kelimutu National Park‟s area.
