Abstract
The aims of this study were to evaluate the quality of feedstuff as concentrate feed raw material, the quality of feed concentrate, and customer satisfaction toward concentrate quality produced by the cooperative. The parameters observed were nutrient contents (moisture, ash, crude protein, crude fat, and crude fibre) and physical quality (density, bulk density, and compacted bulk density). Farmer satisfaction was measured using customer satisfaction index (CSI) and gap analysis. The data obtained consisted of primary data (nutrient content of feedstuff and physical quality) and secondary data (nutrient content of concentrates) that were then analysed descriptively. Total respondents in the satisfaction analysis were 100 farmers. The results of this study indicated that feedstuff nutrient content varied, even though corn gluten feed (CGF) was in the range of Indonesian National Standards (SNI). The highest density and bulk density were limestone, and the highest compacted bulk density was salt, while the lowest physical quality was coffee chaff. Nutrient content of concentrate complied with SNI except for crude fat content. Meanwhile, the physical quality of the concentrate was still within the normal range. Farmer satisfaction was in the satisfied category with the highest gap values absence of foreign objects.
 Key words: concentrate feed, CSI, farmer satisfaction, feedstuff, quality
Highlights
Many types of cooperatives exist in Indonesia
Physical qualities were tested on feedstuff and concentrate samples produced at cooperative, in the form of density, bulk density, and compacted bulk density based on the Khalil method (Khalil 1999)
8%, respectively with at least 2.5% of crude fat content (BSN 1998b), and the results showed all nutrient content was in the standard range
Summary
Many types of cooperatives exist in Indonesia One of those that have a significant role is cooperatives in the agriculture and livestock field, such as dairy farmer cooperative. Dairy farming can’t be separated from dairy cooperatives They have a substantial role for the society that produces high quantity and quality of milk to fulfil the demand. It can be easy to get information managing livestock or get some products that will support farmers' businesses. Cooperatives supply concentrate as one type of feed to meet dairy cows' daily needs (Resti et al 2017). Concentrate feed production is a way to help increase milk production because forage only difficult to fulfil cow's requirement due to competitive land among plant forage, agriculture, and tourism area. Giving concentrate as cows’ feed is one of the resources to reduce waste from agriculture since concentrate feed is formed by mixing various agricultural by-products
