Enterobacter xiangfangensis and Enterobacter cloaceae are known to have the ability as a phosfat solubilizing and producing hormone IAA. Their also have ability to survive under drought stress in vitro assay conditions. Both of these bacteria has good potential as a potato plant growth promoting bacteria, especially in drought stress conditions. This is an alternative to improve tolerance and growth of the potato crop in drought stress conditions. The results showed that the level of drought stress 75% of field capacity can boost the potential of endophytic bacteria E. xiangfangensis in increasing leaf area, plant dry weight, root length and physiological activity i.e total phosphorus content in potato plants. Endophytic bacteria E. xiangfangensis is better to increase potato plant height than endophytic bacteria E. cloaceae. These results are supported by the results of potential test of E. xiangfangensis which have the advantage of producing hormones IAA compared with E. cloaceae. Furthermore, in drought stress conditions 50% of field capacity and 75% of field capacity have different effects on the observations of root length growth parameters potato plants.

The low level of farms income from agricultural sector mainly happens in dry season had to inappropriate soil cultivation. The utilization of soil for brick ste manufacturing is one of this case. The excavation process occurs on top soil inflicting degradation of soil fertility. Soil in the impact of this condition has a problem in providing chemical element for the agriculture, especially the lack of N. One of alternative attempts to increase the soil fertility in providing N on formerly brick ste excavation-soil is by supplying Petroganik fertilizer and compost. Petroganik and compost is an organic fertilizer containing N, P, K, the other nutrient, similar to the other organic fertilizers. The aims of the research are to determine the effect Petroganik fertilizer and compost application on N uptake and toward the growth of corn on former brick ste excavation-soil, and to know the chosen dosage which is resulting in growth and N uptake of corn. Research used is Random Block Design with 9 treatment and 3 replication. Dosage of treatment T0 : Control, Petroganik (14, 17, 20, 23) t/ha and compost (14, 17, 20, 23) t/ha. Indicator plant was used Hybrid Corn BISI 2. The result of experiment showed that : 1. Significant effect in increasing uptake of N the corn. The treatment of Petroganik 17 t/ha (P2) increasing 145 % and compost 14 t/ha (P2) increasing 93.8 %, 2. Insignificant effect on plant growth (height, number of leaf) However, it gives significant effect on dry weight of the corn biomass. The treatment Petroganik 17 t/ha (P2), increases 101.45 %, 3. The application of Petroganik fertilizer is more effective in increasing the growth and N uptake of corn than that of compost since the application of 17 t/ha of Petroganik has already increased the N uptake and growth of corn .

Labuangkallo is a village in costal area, located on the bay of Apar, in the boundary of57 km2 national park. Based on the map of hydro oceanography (1980) and bathymetry measurements (2011), there has been changing of coastline during 31 years.It showed significant changes, especially in the protrusion showed abrasion of 4.9507 m / yr. In the review and direct observation, the issues are grouped into three (3) major parts: (a) Labuangkallo river estuary is getting narrow due to sedimentation; (b) Fishermen settlement was eroded by waves, and (c) mangrove forest was destroyed by abrasion. The source of obstruction is, there is magnitude of the waves from the northeast and east coast, and it abrades the land, especially in area of protrusion / headland. It made angled waves against the shoreline andthe wave forces shaping currents that carry sediment along the coast due to abrasion and deposited on the edge of the river Labuangkallo. The conseravation strategy is usingmechanical method is hard treadment by coastal protector constructionand HDPE sand bag materials, there of the vegetation method with soft treadment using mangrove vegetation along the coastal village. Both are considered the strategies forreclamation.

Person with disabilities has different needs than normal individuals. This difference causes limitations in movement and orientation. As a designer, of course in creating facilities can be used all levels of society, so the need for special treatment in design. Part of architectural context other than buildings is open space. Open space has another function, as a circulation path can also be developed in the form of park. Benefits for people with disabilities, parks can also be a means of learning, training independence and therapeutic areas. In the case study selected location in SLB-C Lawang (tuna grahita or mental retardation), this location has a large area for the development of garden design of motor development and mental children with disabilities or called educational park. The park is divided into two zones: active and passive. The active zone consists of a children's playroom and a sensory park that trains the senses of the five senses, while the passive zone as a park to be visually enjoyed. Therapeutic activities for mental retardation are not just for healing but to practice the senses' abilities of smell, taste, touch, and listener. Initially still an open space that has not been functioned specifically. The problem in this research is how the concept of accessibility and vegetation so that facilities can be used. The objective of the study was to develop a system in parks that can be enjoyed by people with disabilities and as a means of therapy. The result of this research is a concept of ease of achievement of garden for children with disfigured attention to detail of circulation design and variety of vegetation that support the concept of sensory garden so as therapy area.
