The aims of this research was determined from yield analysis on the leaves extract of Sansevieria trifasciata and Sansevieria cylindrica. It was also determined by the presence of bioactive compounds that have the potential as antioxidants (phytochemical screening) on the leaves extract of S. trifasciata and S. cylindrica.The method used was a stratified extraction method with three types of solvent, ie non-polar solvent in the form of N Hexan; A semi-polar solvent of Aceton; And a polar solvent of Ethanol. The identification of six types of phytochemical compounds, the triterpenoid and steroid compounds, saponins, phenols, flavonoids, quinones and alkaloids. The result of rendement analysis showed that S. trifasciata yield was higher than S. cylindrica. The yield of S. trifasciata was 7.89 % and S. cylindrica 6.79%. The result of phytochemical compound analysis obtained three phytochemical compounds contained in S. trifasciata, named triterpenoid group compounds and steroids and flavonoids. Meanwhile, the results of the analysis of phytochemical compounds contained in S. cylindrica also obtained three phytochemical compounds, namely triterpenoid compounds and steroidal groups and alkaloids.

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. Keywords : Type Packaging, Temperature Storage Room, Sorghum Seed Viability

The aims of the research was to identified effect of biological processing of the palm oil by product on nutrient parameters on ruminant. Fungi was used in this research was Sacharomyces cerevicae . After the processing, palm oil by product was added into basal rations. Latin square design was used . The research used four cattle as matterial trial . The treatments was arranged R0= basal rations (70 % consentrate+30% forage), Rz=85% basal rations+15% combinations of palm press fiber and palm oil sludge, R2= 70% basal rations+30% combinations of palm press fiber and palm oil sludge, R3=55 % basal rations+ 45% combinations of palm press fiber and palm oil sludge. The result showed that the treatments had no significant effect on rumen parameters and dry matters consumptions (P<0.05). Digestibility parameters had significant effect (P>0,05). Based on least significant different test, substitution palm oil by product on 30 to 45% could decreasing nutrient digestibility both dry matter, organic matter, protein, and crude fiber. Based on nutrient digestibility parameters, palm oil by product can be used up to 15%. Keywords : Palm oil by product, digestibility

Phalaenopsis amabilis cultivated have many constraints such as the appearance of fusarium wilt disease caused by Fusarium oxysporum. Plantlet P.amabilis which resistant to F. Oxysporum was selected in the solid Vacin and Went (VW) medium was added with salicylic acid at concentrations of 65 ppm, 75 ppm, and 85 ppm, compared with controls (0 ppm). The goals of the research were to study and determine of: 1) The SA concentration of planlet P. amabilis selection tolerant; 2) The proper concentration of AS during in vitro selection for suppressing the Fo. The research was carried out in December 2015 to February 2016 in the Botany Laboratory (in vitro research room), Departement of Biology, Faculty of MIPA, Lampung University. The result showed that: 1) The SA tolerant concentration for plantlet selection with P. amabilis was between 65 ppm - 85 ppm. 2) The 85 ppm of SA was effective for suppressing the Fo compared to 65 ppm and 75 ppm.

The aim of this study is to determine the effect of the number of plants per hole on seed vigor of all sorghum varieties. Experiment is prepared by treatment with randomized block design (RAK) and repeated three times to do to achieve that goal. The first factor is the number of plants per hole that is 1 plant / hole (p1), 2 plants / hole (p2), 3 plants / holes (p3), and 4 plants / hole (p4). The second factor is the variety Numbu (g1), Keller (g2), and Wray (g3). The seed that had been harvested from each of the combination treatments in the test vigornya through germination test method Rolled Paper Test (UKD). Prior to germinate, seeds treated quickly with imbibition pengusangan on rice paper damp ethanol 8%. The results showed that the population of one plant per hole produces seeds with higher vigor than those harvested from other populations. Numbu varieties produce seeds with higher vigor than varieties Keller and Wray especially on untreated seed pengusangan quickly. Population 1 plant per hole produces the best vigor compared with a population of 2, 3 and 4 plants per hole on the three varieties of sorghum seed.

The experiment has been conducted in Labuhan Dalam, Tanjung Seneng, Bandar Lampung from January to June 2008. This experiment consisted of 3 subtitles that are: (1)The effect of root stock age and shading degrees on physic nut plant propagation with grafting. Is a factorial experiment (3x4) with split plot design, shading degrees as main plot consisted without shading, light shading), moderate shading, and heavy shading .Root stock age as subplot consisted 6, 8, and 10 weeks after transplanting; (2) The effect of root stock high and scion length on physic nut plant propagation with grafting. Is a factorial experiment (3x3) with randomized completely block design, the first factors were root stock high consisted 10, 15, and 20 cm from nursery medium. The second factors were scion length consisted 5 cm, 7,5 cm, and 10 cm; (3) The effect of kind of bend and IBA concentration on physic nut plant propagation with grafting. Is a factorial experiment (3x3) with randomized completely block design, the first factors were kind of bend consisted raffia rope, plastic rope, and faucet cellophane tape rope. The second factors were IBA concentration consisted 0, 1000, and 3000 ppm. The treatments were consisted 3 replication and each experiment unit consisted 10 seedlings. The result shows that (1) root stock age 8 and 10 weeks produces physic nut seedling growth better than root stock age 6 week. Physic nut seedling without shading and light shading (1 layer paranet) grow better than with moderate shading (2 layers paranet) and heavy shading (3 layers paranet); (2) Root stock high 15 cm produce physic nut seedling growth better than root stock high 10 cm and 20 cm. Length of scion 7,5 cm and 10 cm produces physic nut seedling growth better than length of scion 5 cm; (3) Plastic and faucet cellophane tape rope produce physic nut seedling growth better than raffia rope.
