Judul: Penambahan Turunan Selulosa dan Whey Sebagai Penghambat Penyerapan Minyak untuk Meningkatkan Mutu Produk Fried Snack
Abstrak: Produk fried snack merupakan makanan selingan yang sangat digemari di Indonesia. Hal ini dapat dilihat dari banyaknya makanan yang digoreng baik di tingkat rumah tangga maupun industri. Karena kesadaran masyarakat yang meningkat di bidang kesehatan, masyarakat mulai mengurangi konsumsi minyak dalam makanan sehari-hari. Hal ini dapat dilihat dengan meningkatnya tren healthy food dengan klaim rendah lemak. Oleh karena itu, industri mulai mencari cara untuk menurunkan penyerapan minyak ke dalam produk fried snack. Penelitian ini bertujuan untuk mempelajari pengaruh turunan selulosa dan whey yang diperkirakan dapat menurunkan penyerapan minyak dan juga pengaruhnya pada bilangan asam dan peroksida minyak. Turunan selulosa merupakan selulosa yang mengalami penggantian pada gugus hidroksinya. Turunan selulosa yang digunakan pada penelitian kali ini adalah dua jenis metilselulosa (MC) dan satu jenis hidroksipropil metilselulosa (HPMC) sementara model pangan yang digunakan adalah pilus. Turunan selulosa dan whey memiliki kemampuan untuk membentuk film yang dapat menghambat penyerapan minyak ke dalam pilus.

Judul: Pemanfaatan Tepung Daging- Tulang Leher Ayam Pedaging pada Pembuatan Makanan Ringan (Snack) untuk Meningkatkan Nilai Gizi
Abstrak: Snack quite popular in Indonesia, it was practical and long storage characteristics made them highly consumed. Broiler’s neck meat and bone meal is one of animal byproduct from animal product industries. It can change into meal and as an alternative source of proteins and minerals. Snack products commonly doesn’t have a balanced nutritional composition, so this research conducted to study the making of snack which increasing with broiler’s neck meat and bone meal and to evaluate the physical characteristic, nutritional composition and consumer’s acceptability of products. The nutritional content observed from the product consisted of water, protein, fat, carbohydrate, ash, calcium and phosphor. The physical analysis observed consist of hardness, kamba’s density and objective color analysis. An organoleptic test was also done. Experimental design used in this reseach was Completely Randomized Design with broiler’s neck meat and bone meal concentration as the response which five concentration stages 0%; 2,5%; 5%; 7,5% and 10%. Each stage consist three replications. The data was analyzed with Analysis of Variance and if the result was significantly different, it was followed with Duncan’s test. The panelist acceptability data was analyzed with Kruskal Wallis and if the result was significantly different, it was followed with mean rank different test that built by Gibbons. The results of nutritional content analysis seen that the water content ranged from 4,53-4,11%; protein content of 9,87-16,15%; fat 21,87-24,85%; carbohydrate 61,09-47,78%; ash 2,62-7,09% calcium 0,029-0,588% and phosphor 0,063-0,095%. The nutritional content analysis result showed that increasing that broiler’s neck meat and bone meal make significantly differences. The physical characteristic result showed that increasing of broiler’s neck meat and bone meal didn’t make significantly differences to fragility and kamba’s density. The average of fragility was 1611,08±43,80 gram force and 1,083±0,005 g/ml for kamba’s density. Objective color analysis showed that increasing of broiler’s neck meat and bone meal incline lower yellowness and got dark to the snack product. The result of organoleptic test to the colour, chicken taste and crispiness gave very obvious influence. The texture and general appearance of the snack didn’t give obvious influence.

Abstrak: This research was conducted to evaluate radiographs heart size of anaesthetized New Zealand White rabbits (Oryctolagus cuniculus) under different combination of ketamine and xylazine. The rabbits were divided into three groups. Group A were anaesthetized using a 35 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=5). Group B were anaesthetized using a 40 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3) while group C were anaesthetized using 45 mg/kg and 5 mg/kg combination of ketamine and xylazine (n=3). Parameter of observation from left laterolateral view were: 1) the apicobasilar length of the heart (AB), 2) the width of the heart (CD), 3) the distance between the cranial edge of the fifth rib and the caudal edge of the seventh rib perpendicular to the spine (R5-7), and 4) the vertical depth of the toraks (H). Parameter of observation from dorsoventral view were: 1) the length of the heart (L), 2) the width of the heart (W), and 3) the width of the thorax (T). The result from the heart parameters observation that were measured in left laterolateral view and dorsoventral view shows theres no significantly differ among the groups (P > 0.05). The vertebrae heart size (VHS) values obtained from the sum of the length of the long and the short axes on left laterolateral view. The long axes mean values (A) were 4.35±0.26 v and the short axes mean values (B) were 3.59±0.30 v, therefore VHS mean values were 7.94±0.49 v. On the dorsoventral view, the length of the heart mean values (L) were 4.32±0.29 cm, the width of the heart mean values (W) were 3.33±0.26 cm, and the width of the thorax mean values (T) were 5.85±0.30 cm. In normal conditions, the width of the heart should be less than two-thirds the width of the thorax and values obtained of 3.33<3.72 it shows that the heart is in the normal range. The best ratio to calculated the normal heart dimension in the left laterolateral view was compared the long axes with the vertical depth of the thorax, whereas in dorsoventral view, the length of the heart was compared with the width of the heart.
