Abstract

Forage is the main source of feed for ruminants, both for basic living, growth, production and reproduction. The provision and quality of forage will determine the productivity and development of ruminants. To achieve this, several quality and high production forages have been developed, one of which is Setaria Grass. The way to improve grass product and quality is fertilization using organic fertilizers. Research has been carried out with the aim of knowing the quality of Setaria grass (Setaria sphacelata) fed with cow manure and goat manure with different doses. This study used a 4 × 2 factorial randomized block design (RAK), where 2 types of fertilizer treatments (Factor A) and 4 fertilizer dosage treatments (Factor B) consisted of 8 treatments, namely: D0S without the addition of cow fertilizer), D1S (addition Cow Fertilizer 10 tons / Ha), D2S (Addition of Cow Fertilizer 20 tons / Ha), D3S (Increase Cow Fertilizer 30 tons / Ha), D0K (Without Addition of Goat Fertilizer), D1K (Addition of Goat Fertilizer 10 tons / Ha), D2K (Addition of Goat Fertilizer 20 tons / Ha), and D3K (Addition of Goat Fertilizer 30 tons / Ha). Each treatment was repeated 3 times. The results showed that the type of fertilizer (Factor A) had a significant effect (P <0.05) on the levels of ash, crude protein, crude fiber and fat. Fertilizer dosage (factor B) significantly (P> 0.05) the content of crude protein, crude fiber and crude fat. There was an interaction between the type of fertilizer and the fertilizer dose on the ash content, and crude fiber of Setaria sphacelata grass

Abstract

Noodles are a food product that is widely consumed by Indonesians. Noodle products, in the form of wet noodles, dry noodles, and instant noodles, have now become the second main food ingredient for Indonesians after rice. The practical nature of noodles makes it easy for consumers to process them into various dishes (Larasati, 2015). However, consumption of noodles has the opportunity to reduce the country's foreign exchange because noodles are made from wheat flour, an imported commodity. The choice of corn as a substitute for wheat flour is because corn is a commodity that contains adequate nutritional value. This study aims to determine the ratio of corn flour to wheat flour and the addition of CMC to the characteristics of corn noodles. The design used was a completely randomized design (CRD) factorial pattern with two factors and two replications, namely the first factor, the ratio of corn flour to wheat flour consisting of 4 levels: (100: 0), (80:20), (70: 30), (60:40). The second factor was the addition of CMC which consisted of 4 levels, namely: (1%), (2%), (%), (4%). Observations were carried out objectively including: moisture content, ash content, fat content, protein content. Meanwhile, subjective observations include: color, texture, taste and overall acceptance. The best research results were obtained in the treatment of 70% corn flour and 30% wheat flour with the addition of 1% CMC with the results of 67,39% water content, 1,00% ash content, 3,92% fat content, 6,14% protein content, and subjectively get the highest favorite score. Compared with the Indonesian National Standard (SNI) No. 2987-2015), it is found that the treatment has met the quality requirements. Except for the value of water content and ash content which are still high, and are still accepted by consumers.
