PENGARUH PROPORSI TEPUNG IKAN DAN TEPUNGKEONG MAS (Pomacea canaliculata) YANG BERBEDA SEBAGAI BAHAN BAKU UTAMA PEMBUATAN PAKAN TERHADAP PERTUMBUHAN BENIH UDANG VANNAMEI (Litopenaeus vannamei)

Feed is the main source of nutrients to support vannamei shrimp growth. The high cost of feed in operational costs due to the high raw material price of fish meal, limited availability, while the demand is high. Therefore it is necessary to find alternative materials that are low in price, have a high enough protein content and abundant availability such as golden snail flour. The purpose of this study was to analyze the effect of different proportion of fish meal and mashed snail (Pomacea canaliculata) as the main feedstock for the growth of shrimp vannamei (Litopenaeus vannamei). The experimental design used in this study was Completely Randomized Design (RAL) consisting of 5 treatments, namely A (57.18% use of fish meal in feed), B (42.89% use of fish meal, 14.30% mashed flour), C (28.59% fish meal usage, 28.59% mashed snail), D (Use of 14.30% fish meal, 42.89% mashed snail), and E (Use 57.18% golden snail flours). This study shows that the addition of mashed snail flour in the feed can increase the growth of absolute weight, the daily weight of vannamei shrimp, and can decrease the value of FCR.

Contribution of Golden Apple Snail Flour to Enhance Omega- 3 and Omega-6 Fatty Acids Contents in Weaning Food

The case of undernourished children in Grobogan District (15.3%) is caused by children nutrients intake less than the Recommendation Dietary Allowance (RDA). To enhance children nutrients intake, be required formulation of weaning food using high-nutrient local food such as golden apple snail (Pomacea canaliculata). Golden apple snail flour contains high contents of zinc, iron, omega-3 and omega-6 fatty acids. This study aims to analyze the effect of golden apple snail flour substitution on nutrients content and organoleptic properties of weaning food (baby porridge). This is an experimental research by substitution of golden apple snail flour in the making of weaning food with four treatments of substitution (0%, 5%, 10%, 15%). Substitution of golden apple snails flour could affect the nutrient content levels of fat, zinc, iron (p=0.0001), carbohydrate (p=0.011), water (p=0.003), ash (p=0.001), omega-3 and omega-6 fatty acids. Whereas, it could not affect the content of energy (p=0.678), protein (p=0.129) and fiber (p=0.482). Furthermore, the substitution could affect the organoleptic properties include color, texture and taste (p=0.0001) while not for the aroma (p=0.798). Based on nutrient content analysis, substitution of golden apple snail flour could enhance the zinc, iron, omega-3 and omega-6 fatty acids contents of weaning food.

Natural Medium for Growing of Endophytic Bacteria from Solanaceae in Malang-Indonesia

Endophytic bacteria are important microorganisms having potential as biocontrol agents for many pathogens. Until now, the growth of it always uses semi-synthetic or synthetic medium so it was difficult to be used by farmers in the field and it was expensive to have its propagation as biocontrol agents. Based on the problem, this research will study the natural medium as propagation medium of Endophytic bacteria. It had natural ingredients such as soybean, chicken broth, egg, worms, snail, sorghum and they were easy to get by farmers. This study used endophytic bacteria from Solanaceae in Malang- Indonesia. Four isolates of endophytic bacteria were grown in agar and liquid medium with ingredients of corn flour, soybean flour, sorghum flour, snail flour, and worm flour. There is no difference in the incubation period, color, shape, and surface colony. The population in medium with snail flour ingredients at a concentration of 10 7 cfu/ml is the highest and snail flour is the best medium for growing endophytic bacteria.

Research is conducted to examine the effect of fast method’s forced molting and snail flour supplementation on yolk follicle growth of chicken (Gallus turcicus). In this research, female chicken is used with 1.5 years of age and 1.2 ± 2 kg body weight. The treatments include the fast method’s forced f molting (without food for 0 hour, 72 hours, and 168 hours, but with drink ad libitum) and snail flour supplements of 6 %, 12 %, and 18 %. <br /> The observation is concerned with yolk follicle growth attributes such as ovary weight and yolk follicle sizes, such as large, medium and small. The data obtained is analyzed by ANOVA. Result indicates that the treatment of fast method’s forced molting and snail flour supplementation does not have effect on yolk follicle growth of chicken (Gallus turcicus). It is evident as reviewed from the ovary weight and from yolk follicle sizes of large, medium and small. Such phenomena is revealed through data related to fast method’s forced molting and snail flour supplementation, in which both are without effect on ovary weight and large follicle size, but with effect on medium and small yolk follicle sizes.<br /><br />Keywords: Chicken, forced molting, snail flour, yolk follicle <br /><br />
