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.

Judul: Optimization Supplement Formulation Based on Virgin Fish Oil Tuna Eye Ball Using Mixture Design
Abstrak: Stunting merupakan permasalahan gizi serius di Indonesia, sehingga pemenuhan protein dan docosahexaenoic acid (DHA) menjadi solusi dalam pencegahan. Ikan kayu dan mata tuna mempunyai prospek yang menjanjikan dalam pemenuhan protein dan docosahexaenoic acid (DHA). Penelitian ini bertujuan menentukan optimasi formulasi suplemen kehamilan berbasis virgin fish oil mata tuna dan hidrolisat protein ikan kayu dengan metode mixture design. Tahapan penelitian, meliputi preparasi, ekstraksi, dan determinasi profil virgin fish oil mata tuna, hidrolisis dan determinasi profil protein ikan kayu, serta optimasi formulasi dengan rancangan statistik mixture experiment {3,1} simplex-lattice design with axial points. Persentase formula optimal yang diperoleh 40.89% untuk variabel virgin fish oil mata tuna, 25.69% hidrolisat protein ikan kayu serta kuning telur 33.40% kuning telur. Sumbangan DHA yang didapat 210 mg sesuai dengan kebutuhan harian DHA ibu hamil, sehingga rancangan formula suplemen diharapkan menjadi sebuah solusi dalam mencegah stunting, Stunting is a serious nutrition issue in Indonesia, and from nutrition aspect, protein and docosahexaenoic acid (DHA) are the important to prevent it. Katsuobushi and tuna’s eyes have promising prospects in fulfilling the adequate amounts of protein and docosahexaenoic acid (DHA) for dietary intake. The purpose of this research was determining the optimal formula for tuna’s eyes virgin fish oil and katsuobushi protein hydrolysate based pregnancy supplement by applying mixture design method. This research was done in some steps, started from preparation, extraction, and determination profile of tuna’s eyes virgin fish oil, hydrolysis and determination profile of katsuobushi fish protein, and formula optimization using a mixture experiment {3,1} simplex-lattice design with axial points. The optimal percentages for each variable of the product were 40.89% of tuna’s eyes virgin fish oil, 25.69% of katsuobushi protein hydrolysate, and 33.40% of egg yolk. The development of optimal formula resulted in a product containing nutrition of 210 mg DHA, which can fulfil the average requirement dietary intake for pregnant women and become a solution for stunting prevention.

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.
