A study of design and evaluation of “golden year” themed vertical garden had been done in Salaran, Wates Village, Semarang Regency. It was aimed to design, apply, and evaluate the vertical garden as a visual object. The methods used were observation, primary and secondary data collection, interview, and sketch design. Respondent’s perception of the visual object in terms of function, implementation of design principles, and aesthetical value was measured with Likert scale and scenic beauty estimation. The conclusions are: 1) a “golden year” themed vertical garden had been successfully created in a sketch by using sketchup software which is applied through a softscape of red bromelia, green Bromelia, Adam and Eve, and ornamental broccoli; and a hardscape of mahogany wood, geotextile carpet, UV plastic, and automatic irrigation system. 2) The “golden year” themed vertical garden was functioned to create visual effect, make a landmark, gives inspirations, and increases the diversity; but it was less functioned as the wind breaker. Unity, accentuation, proportion, accessibility, safety, and appropriate hard scape selection had been applied; but balance, rhythm, circulation, and the durability of materials were still less seen. The “golden year” themed vertical garden can improve the aesthetical value of its landscape. Keywords: Vertical Garden, Golden Year, Design, Design Application, Design Evaluation.

Oil palm plantation expansion in Indonesia continue to increase year by year. Several varieties of oil palm have been produced but not much information about the growth characteristics. Urea as nitrogen fertilizer has become a staple for the cultivation cycle of oil palm. The determination of nitrogen use efficiency (NUE) on palm oil varieties can be used to find out N requirement of each plant according to their needs. This research was aimed to analyze the growth response and NUE of palm oil varieties to fertilizer N at pre nursery. It was conducted in nursery area at Yos Sudarso Binjai Street and Pusat Penelitian Kelapa Sawit, Medan from November 2016 until March 2017 using Completely Randomized Block Design followed by Scott Knott test at α = 5%. There were 35 treatment combinations that used seven varieties of Dura x Pisifera Medan Palm Oil Research Center (AVROS, Simalungun, PPKS 540, Yangambi, PPKS 718, PPKS 239, and Langkat) with N consisting of 5 levels (0 ; 0,5 g ; 1 g; 1.5 g and 2 g). The results showed that the application of N fertilizer influence significant effect on the growth of stem circumference and the number of leaves. The highest of nitrogen use efficiency is found in Simalungun varieties with N application of 1,5 g/plant.

Azotobacter is Plant Growth Promoting Rhizobacteria through the mechanism of nitrogen fixation and phytohormon production but this rhizobacteria has a role to control plant diseases. The objective of experiment was to evaluate the activity of Azotobacter as biofertilizers as well as biocontrol on long bean cultivation in damping off endemic land in Ambon city, Maluku Province. The field experiment was arranged in completely randomized block design. Inoculation of long bean by Azotobacter has been done by seed inoculation, soil inoculation before planting, and plant inoculation. Plants treated with Azotobacter received fertilizer NPK of ¾ or ½ dosage recommendation while control plants were received 100% NPK. Research showed that no differences between yield of long bean inoculated with Azotobacter sp +reduced doses of NPK with that of control plants. Any application method of Azotobacter inoculation lowered damping off diseases incidence significantly until 10 days after planting, but no effect of inoculation on late blight at 21 days after planting. This study confirmed that Azotobacter has dual activity to reduce the dose of NPK fertilizer and control damping off.
