Abstract

Curd is a traditional fermented buffalo milk from West Sumatra.Fermentation in curd making occurs spontaneously, meaning thatfermentation occurs naturally without the addition of a starter. This studyaims to determine the nutritional content of cow milk curd with the additionof avocado extract (Persea americana, Mill) various levels using Gombongbamboo (Gigantochloa verticilata).This research was conducted at the Analogy and Physiology Laboratory ofthe Faculty of Agriculture, University of North Sumatra in November 2018-December 2018. The design used in this study was a completelyrandomized design (CRD) with 5 treatments and 4 replications. Theparameters analyzed were Protein, Fat, and pH. The results showed thatcow milk curd with the addition of avocado (Persea americana, Mill)extract various levels using Gombong bamboo (Gigantochloa verticilata)significantly had different effects on the nutritional value of protein, fat andpH. From the nutritional value studied, the highest protein: P1 7.57% withthe addition of avocado fruit extract (Persea americana, Mill) 6%, fataverage: P1 7.08% with the addition of avocado fruit extract (Perseaamericana, Mill) 6%, pH: P4 5.30% with the addition of avocado fruitextract (Persea americana, Mill) 24%.

Abstract

Indigofera zollingeriana as animal feed contain high protein and a goodalternative source of feed for livestok. In North Sumatera Province, now adaysIndigofera has been introduced to livestockers. This study aims to determine theeffect of scarification by soaking KNO3 (potassium nitrate) on seed germination andearly growth of Indigofera zollingeriana. This research was carried out at AnimalProduction Laboratory; Animal Husbandry Study Program, Faculty of Agriculture,University of North Sumatra Jl. A. Sofyan No. 3 Medan, which began from November2018 to January 2019. The design used was a factorial completely randomized design(RAL) with 12 combination factors, each of which contained 3 replications where eachreplication contained 15 seeds of Indigofera zollingeriana. The treatment consisted of2 factors, namely the K factor = KNO3 concentration, K0 = control, K1 = 4 g / l, K2 =8 g / l, K3 = 12 g / l repeatedly, and L factor = soaking time, L1 = 4 hours, L2 = 8hours, L3 = 12 hours .The results showed that the administration of KNO3 and soaking time on Indigoferazollingeriana seeds had a significant effect on the percentage of sprouts, sprout height,and growing power. The conclusion of the use of KNO3 with levels of 4 grams and 8grams has a positive impact on the percentage of germination and height of indigoferazollingeriana and the duration of 12 hours immersion in the seeds of indigoferazollingeriana also gives a positive effect on the percentage of sprouts and sproutheight, and the best percentage of growth is on the use of 8 grams of KNO3 with 8hours of soaking time.

Abstract

Cassava peel was the waste of processing cassava which is promising enough to be used as alternative animal feed. However, cassava peel has a fairly low nutrient content. Fermentation was one of the way to increase the quality of cassava peel. Fermentation used in this research utilized Indigenous Microorganisms (IMO) with the main substance was the cassava peel itself. This research lasted for 3 months started from December 2018 to February 2019 at the Laboratory of Microbiology and Laboratory of Feed Processing Science and Technology Department of Animal Science Faculty of Agriculture University of Sumatera Utara and Laboratory of Agrichemists and Natural Resources at the Industrial Research and Standardization Office of Medan. This research was designed using Completely Randomized Design (CRD) factorial pattern of 3 x 3 with 3 replications, as factor I was the dose of Indigenous Microorganisms (IMO) and factor II was the duration of fermentation. The parameters measured were water content/dry matter, crude fat, crude protein, crude fibre, ash, and Non Nitrogen Free Extract (NNFE) using proximate analysis. The results showed that fermentation of cassava peel using Indigenous Microorganisms (IMO) with the variation of Indigenous Microorganisms (IMO) dose and duration of fermentation give effects, that were increased water content, crude protein, and Non Nitrogen Free Extract (NNFE) and decreased dry ingredient, crude fat, crude fibre, and ash content.
