Conventional tillage system practices for a long time can reduce soil qualities because of soil erosion, soil compaction and depleting of soil organic matter. Conservation tillage such as No-tillage system can be applied as an alternative technique to rehabilitate soil degradation problems.. This research is a part of a long term study of soil rehabilitation that was conducted from 2010 till now, in PT GMP, Central Lampung. Sampling of nematodes was done on April 2013 when the second ratoon RGM 00-838 variety of sugarcane was 9 months old. The aim of this research was to study the effect of tillage and mulching systems on the abundance of several dominant plant parasitic nematodes. Split plot experimental design was applied on this research. Tillage system as the main plots consisted of intensive tillage and no-tillage systems, while mulching system as the sub-plots consisted of no-mulch and mulching with 80 ton ha-1 of fresh bagasee. Nematodes were collected from 0-20 cm deep of soil and extracted by sieving and centrifugation with sugar solution methods at the Plant Pest and Disease Laboratory, University of Lampung. The results of this research showed that there were eleven plant parasitic and seven free-living nematode genera inhabited the PT GMP sugarcane plantation. The three plant parasitic nematode genera dominant were Hoplolaimus, Xiphinema, and Hemicriconemoides. No-tillage system effectively reduce the abundance of Xiphinema and , mulching with bagasse reduced the abundance of Hemicriconemoides. Meanwhile, mulching on No-tillage system more effective to reducing the abundance of Hoplolaimus compared to intensive tillage system. This results suggested that the No-tillage with bagasse mulching system was one of alternative techniques to control plant parasitic nematodes pest of sugarcane plantation. Keywords : Tillage, mulching, sugarcane, plant parasitic nematodes, abundance.

Lettuce (Lactuca sativa L.) is a vegetable plant which consumption in fresh form. Color, texture, and aroma lettuce can beautify also be an ornamental dish of food. Request lettuce until now has not met its full potential, it is because there are obstacles in cultivation that influence the quality and production results. One technique that can be used in the cultivation of lettuce ie hydroponic. The purpose of this study was to: (1) To know the effect of Catalyst Plant on growth and yield of plants in hydroponic lettuce, (2) To know the effect of the concentration of nitrogen on the growth and yield of plants in hydroponic lettuce, (3) To determine the concentration of nitrogen in response to the liquid fertilizer Catalyst Plant. This study uses a randomized group design perfect (RKTS) arranged factorial (5x2) with three replications. The first factor is the nitrogen concentration of 200 ppm, 225 ppm, 250 ppm, 275 ppm, 300 ppm supplied from planting as much as 3 times a day. The second factor is the provision of liquid fertilizer Catalyst Plant (P1) and without giving liquid fertilizer (P0) with a concentration of 2 g / L of water. Interval application of liquid fertilizer once a week until harvest time. Data were analyzed by analysis of variance to investigate the influence of the treatment applied. If there are significant between the treatment continued with the separation of the middle value of Orthogonal polynomial at 5%. Of the two factors obtained 10 combined treatment with 3 replications and obtained 30 experimental units. Each experimental unit planted two plants, so that the overall use of 60 trial plants Catalyst Plant liquid fertilizer application resulted in better plant growth compared without giving liquid fertilizer. Increased nitrogen concentration of 25 ppm, the concentration of 250-300 ppm improve the growth of plant height of 0.02 cm, 0.01 cm long roots, and plant fresh weight of 0.03 grams (11:12%).

Government policies in helping dairy farmers in an effort to meet the capital needs of breeding them is through a policy program Kredit Usaha Pembibitan Sapi (KUPS). KUPS is skim credit used to finance the development of cattle breeding and dairy cattle by businesses with subsidized interest rates. The problems that the distribution KUPS seen through the eyes of a banking institution is (a) the availability of information prospective potential borrowers are still minimal (b) the legality of ownership of assets (c) cattle breeding company still slightly. KUPS program has been rolled out since 2010, meaning that until 2014 the program has been running five (5) years. But the realization of its lending until September 2014, reached 15.42% of the amount of the ceiling of Rp 4.00 trillion. The realization can be said to be too small or fails. Of course there is the small achievements of the bank as an institution that is authorized to distribute funds would need to act professionally and carefully. Given the experience of lending a mass program past such cases KUT (Kredit Usaha Tani) end up with less encouraging. Instead the main purpose of the program is awakened, just the opposite of credit are understood as government social assistance by the debtor (the farmer). So it is very natural that the bank hand is always cautious. The study was conducted in West Sumatra in 2014, data analysis used data a simple cross-tabulation using the primary data and secondary data from interviews with respondents either breeders penmanfaat KUPS and banking institutions as channeling KUPS Keywords: Beef Cattle Development, Venture Capital, KUPS

The efforts to achieve optimal results in the development of oil palm cultivation one of which is the use of the planting medium. Palm oil seedlings require planting medium that has the chemical and physical properties are good. Media palm nurseries generally consist of topsoil are mixed with sand and organic matter which is expected to obtain a good medium fertility premises. Top soil needs more difficult, so we need to look for alternative media to growing media prenursery palm oil. This study used randomized complete design and experiment arranged in seven media with four replications. The applications method of media: 100 % topsoil (A), topsoil and salvinia compost (1:1) (B), topsoil and coir palm oil (1:1) (C), topsoil and salvinia compost (1:2) (D) , topsoil and coir palm oil (1:2) (E), coir palm oil and salvinia compost (1:2) (F) , topsoil , salvinia compost, and coir palm oil (1:1:1) (G). All data were analyzed for variance. Data analysis followed by separation of means using LSD test with significance level of 5%. The resulted showed that both time and applications method of topsoil have affect on growth component. The best application method was topsoil, salvinia compost, and coir palm oil increased dry weight and root dry weight. Keywords: Prenursey, topsoil , salvinia compost, coir palm oil
