Abstract

The function of plant introductions among others is to obtain new cultivars. After the introduction of plants through the process of adaptation and selection can be used as material crosses with cultivars that have adapted well. A cultivar is said superior when it has a high yield, good fruit quality, resistance to pest attack (plant pests), and able to adapt to various environments grow. The aim of this study was obtain a description, test and compare the yield and quality potential of eight varieties of tomatoes grown in the lowland which are expected to serve as a cross parent material in breeding programs. The experiment was arrange by randomized block design with three replications. The data were analyzed using F-test and the results were significantly midpoint test using LSD test at 5% level. Based on observations on eight strains of local tomatoes and introductions have descripted then selected three strains of tomato introductions which has the form of a round (TM 130804, TM 130805, TM 130806) as well as the introduction of two strains of tomato fruit has an oval shape (TM 130801 and TM 130803 ) that can be used as breeding material further.

Abstract

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

Abstract

Fish mortality in the Bay of Lampung not only wild fish, but also fish farmed in cages, especially Ringgung Beach. One which caused by harmful algal abundance that occur was increased input contaminants by both natural and anthropogenic sources. This study aims to analyze the influence of harmful algal blooms (HABs) the amount and frequency of fish mortality in cage Ringgung Lampung Bay. The study was conducted at three research stations based KJA density. The results of the study found 33 species of phytoplankton, 14 species have potential as HABs can cause the death of fish. The highest abundance was kind Cochlodinium that reach 63.738 cells/liter. Phytoplankton diversity index value with the lowest value occurred at station 3 on June 19, 2013 ie the date of 0705. The highest phytoplankton diversity values occurred at Station 2 on June 12, 2013 is 2,451. Uniformity values of phytoplankton in the waters of Beach Ringgung obtained in the high category with a value above 0.5 or close to 1, which indicates that the spread of the individual any kind of relatively evenly. Except at station 3 which has a relatively low value (0.228 on June 19, 2013, 0291 on June 26, 2013, and 0446 on July 3, 2013). Effect of HABs on the fishing mortality rate is indicated by regression analysis. Correlation coefficient at station 1 shows the value of 0.5208. While on station 2 shows 0.6937. Harmful algal blooms shown to affect mortality rates of fish in floating net Ringgung Beach. They have triggered reduced oxygen levels in the water that could potentially cause the death of wild fish and farmed in floating net Keywords: Dead fish, harmful phytoplankton, floating net
