Abstract

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.

Abstract

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.

Abstract

Karakter morfo-agronomik terdiri dari dua jenis yaitu karakter kualitatif dan kuantitatif. karakter kualitatif bersifat diskret dan berupa data skore sedangkan kuantitatif bersifat kontinyu dan terukur. Analisis kekerabatan penting bagi pemulia untuk mengetahui jarak genetik antar genotype dan untuk menentukan tetua persilangan. Diduga terdapat perbedaan hasil analisis kekerabatan genetik berdasarkan data karakter kualitatif dengan kuantitatif. Penelitian ini bertujuan untuk mengetahui perbandingan hasil analisis kekerabatan berdasarkan informasi data kualitatif dan kuantitatif hasil karakterisasi fenotipik padi lokal. Sebanyak 43 padi lokal Jawa Barat digunakan pada kegiatan karakterisasi fenotipik. Karakter kualitatif yang diamati sebanyak 24 karakter dan kuantitatif sebanyak 23 karakter. Karakter-karakter tersebut merupakan hasil karakterisasi MT 2 2014 di Kebun Percobaan Sukamandi-BB Padi. Analisis data menggunakan Minitab versi 14. Hasil penelitian menunjukkan bahwa hasil analisis kekerabatan dengan menggunakan data kualitatif, kuantitatif maupun kombinasi keduanya tidak berbeda nyata pada komponen analisis jumlah Kluster dan level kesamaan. Perbedaan nyata terdapat pada level jarak genetik. Pola distribusi anggota Kluster pada hasil analisis dendogram berdasarkan data karakter kualitatif berbeda dengan hasil analisis dendogram berdasarkan data karakter kuantitatif dan kombinasi. Analisis kekerabatan antar genotipe direkomendasikan menggunakan data kombinasi dari karakter kualitatif dan kuantitatif agar informasi jarak genetik antar genotype lebih valid.

Abstract

Natural peat swamp forests converted can alter the soil chemical properties. This study aims to determine the extent to which changes in soil chemical properties that occur after the conversion of land from peat swamp forest to palm oil plantation, HTI Acacia crasicarpa, and sago plantation and to know which types of plants are sustainable on peatlands. The results showed that soil pH increased after the change of land function. While the water content decreased. Chemical properties such as C-organic, ash content, CEC, alkaline saturation, macro nutrients (NPK) and bases can be changed also undergo changes after undergoing landuse changes, but no violations based on the law made by the government in pp No 25 of 2000 on the criteria of peatland damage and government regulation no. 150 of 2000 on the control of soil damage for biomass production. Sago is the most sustainable plant compared to others due to changes in soil chemical properties not too much different from other landuse although planted in the long term.
