Abstract

KSU Putera Mekar is the first cooperative to own a tea processing factory directly managed by smallholder tea farmers and produce dried tea products called Iroet tea. The beginning of Iroet Tea factory, they sell their products to PT Sariwangi AEA (Agricultural Estate Agency) and other small companies such as Agriwangi and Elinkindo, but it does not go long. PT Sariwangi broke his contract with the cooperative so that the cooperative did not have a large customer anymore. Cooperative members are decreasing because the cooperative is unable to absorb wet tea tops from farmers and can not afford to pay farmers with pay-weight system, but the agro-industry business still survives. This makes the cooperative requires the chronological know the main cause of bad business cooperatives and the reasons for cooperatives to survive. The research design used in this research is qualitative with case study technique. The method used in this research is descriptive qualitative. The results showed that the main cause of bad business cooperatives is the loss of large consumers and the absence of bailout funds. The reason for the cooperative still persists to this day because the cooperative management has a good orientation to improve the business of Iroet tea agroindustry, supported by the loyalty of cooperative members.   Keywords: agroindustry, cooperatives, loyalty, smallholder tea farmer

Abstract

Farmer dependence on inorganic fertilizers drives the inclination of the fertilizer price which in turn influence the production cost. Therefore, it is necessary to find alternative way to reduce the consumption of inorganic fertilizers. This study aims to determine the most suitable arbuscular mycorrhiza fungi (AMF) for oil palm seedlings, determining the best dosage of phosphate fertilizer for the growth of oil palm seedlings, and determine whether the growth response of oil palm seedlings to AMF inoculation is influenced by the dosage of P fertilizer given. Research had been conducted in the greenhouse and Plantation Production Laboratory, Faculty of Agriculture, University of Lampung from June 2012 until August 2013. The treatment design used was a factorial design and the experimental design used was a completely randomized block design. The first factor was AMF treatment i.e. control, Entrophospora sp. mv 3 isolate, Glomus sp. mv 9 isolate, Glomus sp. mv 10 isolate, and Glomus sp. mv 15 isolate. The second factor was the dosage of P fertilizer i.e. 23,32 g, 15,66 g, and 11,66 g per plant. Each treatment was repeated 4 times. The results showed that Glomus sp. mv 15 isolate was the most suitable type of AMF for oil palm seedlings. All dosages of P fertilizer tested showed no growth effect on oil palm seedlings and the growth response of oil palm seedlings to inoculation of AMF was not affected by dosage of P fertilizer. Keywords: Entrophospora, Glomus, mycorrhiza, oil palm, phosphate
