Effect of Soaking and Concentration of Liquid Organic Fertilizer (POC) Cow Urine Against Early Grape Cuttings (Vitis Vinevera. L).
Full text linkuse of vine stem cuttings seeds has the advantage of providing more number of seeds and later new plants which will have properties such as the parent, grapes are already known as one of the classy fruits in the world, both fresh consumed and processed products, processed grape products which is known as wine is able to penetrate the price of Rp5.7 billion per bottle is famously expensive in subtropical countries. This study aims to determine the duration of soaking and concentration of liquid organic fertilizer (POC) of cow urine on the initial growth of grape cuttings. The study was conducted in the Experimental Garden Faculty of Agriculture, Merdeka University, Surabaya Jl. Ketintang Madya VII / 2 Surabaya, with a height of ± 5 meters above sea level. This study uses a randomized block design (RBD) arranged according to factorial patterns with two (2) factors, namely factor I = duration of immersion consisting of 4 levels, including: L0 = 0 minutes (control), L1 = cuttings of grapes soaked for 15 minute, L2 = cuttings of grapes soaked for 30 minutes, L3 = cuttings of grapes soaked for 45 minutes, while factor II = concentration of organic ZPT consists of 3 levels, including P0: 0 ml / liter (water), P1: 10 ml cow urine per liter of water, P2: 20 ml cow urine per liter of water, P3: 30 ml cow urine per liter of water, P4: 40 ml cow urine per liter of water, based on the results of the study, conclusions can be drawn. There was a significant interaction at the F5% test level on the variables studied, namely the length of the vine cuttings at 42 days after planting and was best achieved by a combination of P3L2 treatment compared to other treatments, although it was not significantly different from the combination of P2L3 and P4L2 treatments. significant from both the POC concentration factor and the immersion length factor under study, mainly in the shoot length variable at 42 days after planting. Statistically, a better value for all of these variables is achieved by the P3 treatment that is 30% ml / liter of water and the L2 treatment that is 30 minutes
Effect of Dose And Time of Npk Fertilizer Application on The Growth And Yield of Tomato Plants (Lycopersicum Esculentum Mill)
Full text linkThe purpose of this study is to examine the effect of the dose and time of NPK fertilizer application on the growth and yield of tomato plants (Lycopersicum esculentum Mill). The study was conducted from April to July 2018 at the Experimental Garden of the Faculty of Agriculture, Merdeka University Surabaya, on Ketintang Madya VII-2 Street Surabaya, East Java with altitude of ± 5 m above sea level. The study used Factorial Randomized Block Design (RBD) consisting of two factors with three replications and two sample plants. The first factor was NPK fertilizer doses (N1 = NPK 2 gr / plant; N2 = NPK 4 gr / plant; N3 = NPK 6 gr / plant) and the second factor was the time of NPK application (W1 = day 0; W2 = day 0-14; W3 = day 0-14-28). The results shows that the combination treatment of dose and application time of NPK has a very significant effect on plant height, number of leaves, total fruit number and total fruit weight of tomato plants. The combination treatment of N3W3 (NPK 6 gr / plant and day 0-14-28) appears to produce the highest growth and yield of tomato plants though, statistically (BNT 5%), this was not significantly different from the combination treatment of N2W3 (NPK 4 gr / plants and 0-14-28 days)
Germination variety Test Two Plantcane (Saccharum Officinarum L.) The Use of Breeding Mule Shoots With Different Eyes Lay
Full text linkThe number of clumps per hectare is influenced by the percentage of germination of kinds of seeds used (Tamelsilva, 2006). Increasing the production of sugar cane as a raw material for sugar is absolutely necessary. One of the causes of the decline in sugarcane productivity is the problem in the use of seeds, such as sugarcane seeds used by farmers who are less qualified (Iskandar, 2005). The study was conducted at the Experimental Garden of the Faculty of Agriculture, Merdeka University, Surabaya, in March-April 2017. Using a Randomized Block Design (RBD) consisting of six treatment combinations with three replications and two sample plants. As for the combination treatment, as follows: A (Variety LPS-864 and Buds Buds section 20); B (Variant LPS-864 and Mata Tunas Middle-segment-14); C (Variety of LPS-864 and Mata Tunas at the base of Section-08); D (Variety of LPS-891 and Buds section of Section-20); E (Variant LPS-891 and Mata Tunas Middle-segment-14); F (Variety of LPS-891 and Mata Tunas at the base of segment-08). The results showed that the treatment of the combination of the location of the buds and varieties significantly affected the observation of the number of leaves, but the effect was very significant on the variable of germination speed and length of the plant and the wet weight of the plant. Combination treatment of bud location on segment-20 (shoots) on the sugar cane varieties LPS-891 and cane varieties LPS-864 showed the best results on all observational variables, although the highest results always indicated the location of bud-section 20 buds (shoots) on sugarcane varieties LPS-891, but statistically not significantly different

Analysis of Water Quality Based On Phytoplankton Abundance And Number of Nutrients
Full text linkThe process of development has effect on the existing water catchment area, currently the normalization of the water area is being carried out. The water body is passed by various kinds of waste; domestic and industrial waste, causing water bodies to contain nutrients. Nutrients are a food source for existing phytoplankton. The amount of nutrients and phytoplankton affects the level of fertility and trophic status of each of these water bodies. Samples were collected from Epicentrum Pond, Lake Sunter, Citra Lake 6, Lake Citra 8, Setu Rawa Badak Jatijajar, and Situ Cilodong. The result shows that are samples classified in the class II water quality category according to PP No. 82/2001. The classification is based on the concentration of pH parameters, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Phosphate and Nitrate. While the classification of aquatic fertility is based on the abundance of phytoplankton. The result shows that Epicentrum Pond, Lake Sunter, Lake Citra 6, Lake Citra 8, and Setu Rawa Badak Jatijajar are included in mesotrophic, while for Situ Cilodong are included in oligotrophic. For the classification of trophic status according to PERMENLH No.28/2009 (based on the parameters of nitrate, phosphate and chlorophyll-a), the Epicentrum Pool is included in the oligotroph to eutroph. Whereas for Lake Sunter, Setu Rawa Badak Jatijajar, and Situ Cilodong are included in oligotrophs to mesotrophs. And for Lake Citra 6 and Danau Citra 8 have trophic status from oligotrophs to hypereutrophs
