Kiambang (Salvinia natans) which a water plant became a seriously problem in the use of Reservoir Batutegi, because nearly 80% of its surface covered by Salvinia natans. The presence of highly abundant of Salvinia natans have highly potential to be used as a source of organic fertilizer. The purpose of this study was to examine the effect of the application of biological technology (decomposers) and cow manure on the quality of the resulting compost kiambang. This study used randomized block design and experiment arranged in factorial 4 x 4 with three replications. The first factor was the dose of decomposers which consists of 4 levels, namely A1 = 0 ml, A2 = 20 ml, 30 ml dose = A3, and A4 = 40 ml decomposers per quintal kiambang respectively. The second factor was the dose of cattle dung, i.e. B1 = 0 kg, B2 = 10 kg, 20kg = B3, and B4 = 30 kg manure per quintal kiambang. The results showed the compost that has the best quality in terms of physical and chemical compost was the compost derived from the treatment of 30 ml and 40 ml decomposers per quintal kiambang which combined with 10 kg, 20 kg or 30 kg manure per quintal kiambang. Keywords: Salvinia natans, decomposers, cow manure, compost quality

One of the disadvantages of oil palm development is the limitedness of fertile soil. A constraint faced by both big plantation and small holders is the high cost of crop maintenance. Around 60% of the total crop maintenance is used for fertilizing the crop. This study aims at finding out phosphate absorbtion and the growth of oil palm seedling with the addition of Arbuscullar Mycorrhizal Fungi (AMF) and different dosages of phosphate fertilizer. A factorial Complete Randomized Design with three replications has been used. The first factor was the addition of AMF consisting of three levels: M0=0 g AMF polybag-1, M1=5 g AMF polybag -1, and M2 = 10 g AMF polybag -1. The second factor was the addition of four levels of phosphate using TCP-36: P0= 0 g TCP-36 polybag-1, P =15 g TCP-36 polybag-1, P2=30 g TCP-36 polybag-1, and P3=45 g TCP-36 polybag-1. Results showed that the Application of 10 g AMF polybag-1was able to increase P-absorbtion and the growth of oil palm seeding such as fresh crown weight, dry crown weight, fresh root weight, dry and root weight. Application of 45 g TCP-36 polybag -1was able to increase the growth such as plant height, dry crown weight, fresh root weight, and dry root weight.

Isoprophylamine glyphosate, a common herbicide, is widely used as a sugarcane ripener to hasten maturation and to increase sugar yield in many countries. The ripener also alter the physiology of sugarcane that might consequently affect the development of the sugarcane shoot borer, Scirpophaga nivella intacta Snell (Lepidoptera: Pyralidae). This research studied the effect of isoprophylamine glyphosate on the intensity of S. nivella intacta attacks on several cultivars of sugarcane. Results of the experiment showed that varieties of sugarcanes responded differently after application of isoprophylamine glyphosate. The percentages of damaged nodes by S. nivella intacta were higher following the application of the ripener on GM 21 and RGM 97-10167 cultivars. Conversely, the damage nodes were lower on RGM 97-8752 and RGM 97-10120 at 20-30 days after the application of the ripener. Out of four tested cultivars, GM 21 was in general the most susceptible to the attacks of the sugarcane shoot borer. On the other side, there was an indication that cultivar RGM 97-10120 applied with isoprophylamine glyphosate had the lowest damage level by S. nivella intacta. The cultivar could be further investigated to study wether it has the potential as a better cultivar against S. nivella intacta when isoprophylamine glyphosate is applied as the cane ripener.

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.

Gladiolus propagation effort has been experiencing problems because of active buds on gladiolus corms in normal conditions is generally. Shoots will grow and then will produce tubers. So for rapid multiplication of gladiolus necessary effort to stimulate active shoots found on gladiolus corms. The use of benzyl adenine was effective enough to stimulate the emergence of shoots on gladiolus corms. Earring size seedlings generally will affect the size of the new corms. In general, if the new corms are formed more than one will affect the size of the next Earring. Fertilization-rise is expected to enlarge the size of the corm so that it can directly be used as a corm production. This study aims to find methods of rapid propagation of gladiolus corms by: (1) the effect of initial corm size on the number and size of the new corm, (2) the effect of fertilization dose on the growth of earrings, and (3) the effect of fertilization at each dose respective initial corm size. This study is a continuation of previous studies that aimed to obtain an effective concentration of BA to stimulate the growth of shoots contained in gladiolus corms. This research used the BA 30 ppm (the results of previous studies) is applied to the gladiolus cultivars Kaifa. The treatment applied to the three sizes of 3.8 to 4.8 cm diameter Earring (U1), 2.5 to 3.7 cm (U2), 1.2 to 3.0 cm (U3). The results showed that administration with a concentration of 30 ppm BA, able to grow all of gladiolus corms which were attempted (100% sprout more than one bud), and capable of increasing the number of active buds and number of shoots by 4.6 by 6.4. Keywords: Gladiolus hibridus L, Benziladenin
