This study was conducted to determine the effect of supplements probiotic on layer performance (consumption and conversion ration, persentage hen day and egg weight). This research was held on 21 July?24 August 2014 in the CV. Varia Agung Jaya henhouse laying in the District of Seputih Mataram, Center of Lampung Regency. Local probiotic was made in Microbiology Laboratorium and Moleculer Biology Laboratorium, Faculty of MIPA, Lampung University. The study used completely randomized design with 3 treatments (P1: control ration, P2: control ration with local probiotic 3%, and P3: control ration with comercial probiotic 3%) and 6 replications. Data obtained was analyzed using analysis of variance at 5% level and continued Duncan test at 5% level. Based on the results we can conclude: the effect of treatments significant (P<0.05) on consumption and conversion ration, but no significant (P>0.05) on percentage of hen day and egg weight. Control ration significantly (P<0.05) with control ration with local probiotic 3% and control ration with comercial probiotic 3% on consumption and conversion ration, but no significant (P>0.05) on supplement probiotic.

This study aims to determine: (1) in response to the type of packaging savings and sorghum seed viability; (2) in response to the storage room temperature sorghum seed viability; (3) a combination of types of packaging store and storage room temperature for sorghum seed viability. The research was conducted in October 2013 to January 2014 at the Laboratory of Seed and Plant Breeding, Faculty of Agriculture, University of Lampung. This research is compiled using a completely randomized design with four replications. The design of the treatment applied is factorial (4x3) by the first factor is the type of packaging and the second factor is the temperature store room. Homogeneity of variance between treatments was tested by Bartlett test. Separation of median is done by using the test Least Significant Difference (LSD) at level ? of 5%. The results showed that the seeds of sorghum were packed with cans stored at refrigerator temperature (4 ° C) have the ability better than a plastic jar packaging, cloth flour, and plastic at room temperature (32 ° C) and air conditioning (22 ° C), in maintaining sorghum seed viability after being stored for 4 months.

The purpose of this study was to determine the amount of genetic diversity and phenotype, heritability in a broad sense as well as the numbers of soybean expectations F5 generation from crosses Wilis × B3570 which has a middle value the better of both parents. The experimental design used randomized group design by three replications. Genotypes were tested as much as 25 genotypes. he results showed that the amount of genetic diversity of soybean agronomic characters F5 generation from crosses Wilis x B3570 found in almost all the characters except the characters age observed flowering and harvesting age. The genotype diversity found in all agronomic characters were observed. The magnitude of the high heritability values found in the character of a weight of 100 grains. Heritability values were on plant height, number of productive branches, and the total number of pods. Character weight of seeds per plant, flowering age, and time of harvest had the lowest heritability. Numbers expectation obtained by the genotypes number 163-1-4, 130-2-11, 130-2-11, 163-1-15, 102-3-2, 163-1-1, 140-1-15 , 163-1-6, 181-5-4, 140-1-2 are rated according to the weight of the weight of seeds per plant that would refer to the high production Kata kunci: variability and heritability, and Soybean

The aim of this research to observe and analyze the ability to grow of watermelon seeds in organic and inorganic fertilizers. Observing and analyzing the interaction between the ability to grow of watermelon seeds with plant growth in organic and inorganic fertilizers. Recommend a combination of organic and inorganic fertilizers that provide maximum results. This research was conducted in field of State Polytechnic of Lampung on June until Agustus 2014. This research uses a randomized complete block design (RCBD) with treatment in the form of thiamethoxam, inorganic fertilizers and organic fertilizers, namely: P1 = 0% organic fertilizer + 100% inorganic fertilizer; P2 = 25% organic fertilizer + 75% inorganic fertilizer; P3 = 50% organic fertilizer + 50% inorganic fertilizer; P4 = 75% organic fertilizer + 25% inorganic fertilizer; P5 = 100% organic fertilizer + 0% inorganic fertilizer. Doses of inorganic fertilizers: Urea = 300 kg.ha-1, SP-36 = 200 kg.ha-1, KCl = 100 kg.ha-1. Organic fertilizer: manure (cow manure) = 20 tons.ha-1. Data were analyzed with analysis of variance and if there is a real different treatments followed by LSD test at 5% level. The results showed that organic and inorganic fertilizer application significantly affected fruit length and fruit weight, but did not significantly affect the ability to grow, main stem length and number of leaves. The length of the longest fruit found in the treatment of inorganic fertilizer application of 75% + 25% organic fertilizer (P2). While the weight of the heaviest fruit found in the treatment of organic fertilizer application of 100% (P5). The highest ability to grow plant found in the treatment of 100% inorganic fertilizer application (P1), treatment of inorganic fertilizer application 50% + 50% organic fertilizers (P3), P2 and P5 treatment. The longest length of main stem found in P5 treatment, while the highest number of leaves found in P2 treatment. Keywords: fertilization, organic, inorganic, watermelon

Organonitrofos fertilizer is organic fertilizer derived from cow manure enriched with rock phosphate and microbial activity involves fastening N and phosphate newly developed solvent. This study aimed to determine dose combination Organonitrofos fertilizers and inorganic fertilizers are most effective against the growth, nutrient uptake, and yield of sweet corn. This research was conducted in November 2012 until March 2013 in the Integrated Field Laboratory, University of Lampung using Random Design (RBD) consisting of 6 treatments with 3 groups. Treatment A (control), B (300 kg Urea ha-1, 200 kg of SP-36 ha-1, 100 kg of KCl ha-1), C (225 kg Urea ha-1, 150 kg SP-36 ha-1, 75 kg KCl ha-1, 1000 kg Organonitrofos ha-1), D (150 kg Urea ha-1, 100 kg of SP-36 ha-1, 50 kg of KCl ha-1, 1,500 kg Organonitrofos ha-1), E (Urea 75 kg ha-1, SP-36 50 kg ha-1, 25 kg ha-1 KCl, Organonitrofos 2000 kg ha-1), F (3,000 Organonitrofos kg ha-1). The results showed that treatment at a dose of 150 kg of urea ha-1, SP-36 100 kg ha-1, 50 kg ha-1 KCl, Organonitrofos 1500 kg ha-1 is able to increase the growth, production and sweet corn crop nutrient uptake. This treatment was also the most effective treatment of the total biomass of sweet corn plants based on calculations Relative Agronomic Effectivenes (RAE) that is equal to 108.573%. Economical test results showed that treatment at a dose of 300 kg of urea ha-1, SP-36 200 kg ha-1, 100 kg ha-1 KCl most economical compared to other treatments.

This study aimed to determine the effect of pH on the production of antibacterial by lactic acid bacteria. This study uses a completely randomized design factorial 3X 5 (3 X 5 treatment of bacterial isolates pH) with three replications. The first factor consisted of pH 4, pH 5, pH 6, pH 7, pH 8, and the second factor that isolates B2, B7, B8, whereas the parameters consists of a clear zone. The amount of production is determined by the size of the diameter of antibacterial inhibition zone against Salmonella sp. Differences in the production of antibacterial determined based on the results of analysis of variance. The treatment significantly further test BNT at 5% level. The results showed that the effect of media pH test based on the potential for the production of antibacterial effect. The diameter of the largest clear zone produced by B7 isolates at pH 6 was 17.2 mm, 17.1 mm B8 and B2 at pH 7 at 16.7 mm. The smallest diameter of the clear zone produced by B8 at pH 4 was 15.1 mm, B2 at pH 6 there is a clear zone of 12.7 mm and isolate B7 at pH 5 of 11.5 mm Keywords: Antibacterial, Lactic Acid Bacteria, pH, Salmonella sp, Clear zone
