Abstract

The problem faced in the livestock business is the insufficiency of feed raw materials both in quality and quantity, even though there is a supply of feed using indigofera legumes with physical innovations in the form of mash, pellet and wafer feed. This research aims to test the quality of feed made from indigofera legumes in various forms of mash, pellets and wafers. This study used a completely randomized plan with 3 treatments and 6 replications. The treatment S0 = Mash  feed composition of 50% indigofera legumes + 50% corn bran + 5% binding molasses; S1= pellets composition of 50% indigofera beans + 50% corn bran + 5% molasses; S2 = Wafer composition of 50% indigofera legumes + 50% corn bran + 5% molasses. The results showed that the pellet treatment produced higher specific gravity, pile density and compaction density values ​​(P<0.05) than the mash treatment, furthermore the wafer treatment was superior in producing dry matter and crude protein compared to the mash and pellet treatments. The research conclusion is that wafer feed is superior in producing crude protein and dry matter values.

Abstract

Activities of teacher’s working memory in representing a picture are important in the teaching and learning process. This study aimed to reveal the tendency of teacher’s mental representation and teacher’s teaching styles in biology class using convention pictures. This research used descriptive method. The research was conducted by involving four high school biology volunteer teachers of grade XI from four schools in Lebak, Banten, Indonesia. Teacher’s teaching styles were measured by questionnaires and rubrics adapted from Grasha and teacher’s mental representations were measured using worksheets and rubrics developed based on the Causal Network Elicitation Technique (CNET) model. The data obtained were analyzed qualitatively. The results showed two dominant teacher teaching styles; there were expert style and facilitator style. The mental representation of teachers when reading convention picture was in the category of good (2 teachers), adequate (1 teacher) and inadequate (1 teacher). A teacher with expert teaching style tends to have a good mental representation compared to a teacher with facilitator teaching style.
