Arbuscular Mycorrhiza Fungi (AMF) is a form of mutualistic symbiosis between fungi and plant roots. FMA existence in soil is influenced by several agricultural activities such as tilling and fertilizing. The purpose of this study (1) Obtaining data on the number of FMA in each treatment and conservation tillage . (2) Knowing the types FMA in each treatment and conservation tillage planting season to 29. The study was a randomized block design (RAK) , arranged as factorial (2x3), with three replications. The first factor is the intensive tillage (T1), no-tillage (Zero Tillage) (T2) Minimum tillage (Minimum Tillage), and Land Intensive (Full Tillage) (T3); and the second factor is without fertilizer N (N0) and fertilizer application of 100 kg N ha-1 (N1), and Fertilizer of 200 kg N ha-1 (N2). The method used in this study is a description method by observation techniques, the method used for the isolation of spores of strain engineering castings and followed by centrifugation. Observations were made using a microscope binoculars and digital camera, the spores are observed then grouped based on their morphological characters, identification of mycorrhizal done using a guide book "Working with mycorrhizas in Forestry and Agriculture" and reaffirmed by using INVAM website. Based on results of research and discussion can be concluded. The number of spores in the soil no tillage without nitrogen doses is 1,333 at doses 100 kg N spore number is 1,253, and as high as 1,648 spores at dose of 200 kg N. The number of spores on minimum tillage 200 kg of nitrogen dose was 271, on 100 kg dose was 520 spores, and without nitrogen fertilizer contained spores 780. at most that intensive tillage highest number of spores on spore number without nitrogen fertilizer is 4.078, and the number of spores 1,124 at the dose of 100 kg nitrogen, 941 the number of spores nitrogen dose of 200 kg. There are four genera of spores discovered in minimum tillage with various doses Nitrogen fertilizer is the genus Glomus, Acaulospora, Gigaspora, and Scutelospora. Genus most obtained is Glomus and Acaulospora. Type spores were found from 4 genera dominated by genus Glomus with a variety of different types.

In livestock trading system and cattle product such as meat and other livestock products always involves some businesses that make up the chain of marketing. Tradable commodity that can be distributed right from the producer to the end consumer in the form of live cattle or in the form of livestock product. Distribution activities of livestock and livestock products by land necessarily involves a good means of land transport trains, trucks and other means of land transport. While also involving the various levels of the marketing chain of middlemen village level, large padagang up with retailers. Implementation of the distribution chain between marketing is not just a process of transporting goods. Consistent with the mechanism of the existing business, there will be a new price formation on each node chain path. The longer the chain through which the formation of prices will be higher . Such conditions led to the emergence of the marketing margin distribution on each node marketing chain. The amount of the marketing margin generated between the node is varied, it is largely determined by many things, in addition to the cost of marketing, also the advantage taken by the perpetrator. The study was conducted in East Java and West Java in 2013. Analysis of data using simple cross-tabulation of data derived from primary data and secondary data Keywords: Land Transport, Distribution and Livestock

Soybean is an alternative stapple food which use by all people in Indonesia. However,domestic soybean production does not meet the needs of the national soybean. To meetthe needs done, it important to assemble the soybean breeding to improved the noblevarieties. Plant breeding is largely determined by the ability of breeders to select.Selection can be done by estimating the correlation coefficient between thecomponents of the results and outcomes. To determine the causal relationship betweenyield and yield components used path analysis. Path analysis of correlation coefficientwill break into the direct and indirect influence. The purpose of this study are todetermine (1) the correlation between the components of the results and outcomes; (2)direct and indirect influence between the components of the results and outcomes. Theexperiment was conducted from March to July 2014 in field trials of POLINELA(Lampung State Polytechnic) and in Seed Laboratory of University of Lampung.Soybean seed used is the result of crossing Wilis F6 generation x B3570. Treatmentarranged in a perfect randomized group design with two replications. The results ofcorrelation analysis showed correlation great and positive value indicated by thecomponent total number of pods per plant and grain weight per plant (0.80 *),hundred grain weight and grain weight per plant (0.72 *), and the number ofproductive branches and grain weight per plant (0.57 *). Results of the analysisshowed cross large direct effect on the character of the total number of pods per plantto grain weight per plant (0.89), which is almost as large as the correlation (0.80 *).Then the correlation coefficient was actually measure the degree of closeness of theirrelationship. Therefore, the selection is based on the total number of pods will be veryeffective to get genotype expectations that have high yields.Keywords: Soybean, Selection, correlation, analysis of cross
