Abstract

Microspore culture method can be used as plant breeding program. The preparation of cultivars selection is an important step. The research starts with cultivated five cultivars of soybean i.e: Argomulyo, Grobogan, Wilis, Anjasmoro and Black Malika. The appearence of soybean plant was observed until flowering. Selection of plants based on: sum of flower bud every plant, anther midline, total and diameter of microspore every flower bud was measured by the ‘Optilab’ software. The development of microspore done with grouping of flower bud according long 2.02.5 mm, 2.6-3.0 mm, 3.1- 3.6 mm and 3.7-4.1 mm for chooses flower bud with the most late uninucleate microspore stadium. Result of the research shows that long of flower bud 2.6-3.6 mm contain 1847-2010 late uninucleate microspores, diameter     20 µm for 5 cultivars can be used for material of microspore culture. Anjasmoro cultivar, tall of plant gain 68 cm, sum of rame 7-9, anther midline 354.67±59.67 µm, number of microspores each flower bud 2003±216. Result of responsive qulity test with anther incubation on 340C temperature for 4 days represent the most of total viable microspore, 3.371±45 on Anjasmoro cultivar. Plant breeding by Anjasmoro cultivar is the most appropriate for microspore culture treatment.

Abstract

Ambon as the capital of Maluku Province had been occupied by 3,558 farmers whose farming works have contributed to the production of estate commodities for about 1,169 tons.  There were three estate commodities with significant contribution, namely clove, nutmeg, and coconut. The objective of research was to analyze the characteristics of estate farmers and the contribution of estate commodities on household income. Sample was determined purposively from Nusaniwe District, precisely 30 farmers from Nusaniwe Subdistrict, 60 farmers from Latuhalat Subdistrict, 50 farmers from Amahusu Subdistrict, and 60 farmers from Urimessing Subdistrict. Total sample was 200 farmers. Data were collected using questionnaire and depth interview with key informant. Data on respondent characteristic were analyzed through simple tabulation. Income count was used to analyze the contribution of each estate commodity on household income. Result of research showed that education, number of household member, side-job selection, land width, and commodity species were not varying across subdistricts. Contribution of clove and nutmeg to household income was found as high for 70 – 80 %, while that of coconut reached only 10 – 20%. Side-job activity as fisher and construction worker gave contribution to household income for 5 – 10%.

Abstract

Water level (TMA) and soil temperature are two keys of environmental factors for ecosystem peatland study and for peatland ecosystem sustainability as well as crop productivity on peatland. On the other hand, climate change is another factor that cannot be avoided and affects the peatland ecosystem. Fluctuation of water level and soil temperature more severe on El Niño or dry years. Therefore, monitoring of water level and soil temperature on peatland ecosystem is important for sustainable peat management, especially on the dry years. The study objective was to determine the dynamics of water level and soil temperature on peatlands ecosystem in El Niño years and compare them to the normal year conditions. Water level and soil temperature were conducted automatically on rubber plantations on tropical peatland in Jabiren, Pulang Pisau, Central Kalimantan, from January to December 2015. Water level on the field and canal drainage on tropical peatlands followed the variations of precipitation. Although the average of annual precipitation on El Niño year is almost the same as normal year, but the water level and soil temperature show quite significant differences to the normal years. In addition, even water level was deeper and soil temperature is quite high in the dry season of El Niño years, but this field did not burn because productive plants were growth managed well by the owner.

Abstract

Electrical conductivity (EC) of nursery medium will affect germination and growth of viola (Viola cornuta L.) seedling. The purpose of this study was to determine the influence of various ECs of growing medium on germination and  growth of viola seedling. Research was carried out in December 2016 - January 2017 in nursery room of PT. Selektani Horticulture, Ngablak, Magelang. There were 9 EC treatments repeated 3 times therefore 27 units of experiment were tested. The observed parameters includeds germination rate (DB), and speed (KCT), plant height, number of leaves, shoot dry weight (BKBA) and root dry weight (BKA). Data were analyzed using regression and correlation tests. This study showed that there was a linear relationship between EC and DB as well as between EC and KCT. This is indicated by the following equations y = -20.771x + 99 504 (R2 = 0.9653, n = 27, y = germination (%), x = EC (dS / m) 0 HSS) and y = -5.1109x + 21.6 (R2= 0.8765, n=27, y= KCT (%KN/24hours). The critical EC needed to reach germination rate of higher than 80% was 0.94 dS/m. The correlations between DB and ec as well as KCT and EC were significant: respectively -0.98251 and -0.93621 (n = 27). The Relationships between EC and plant height, number of leaves, BKBA as well as BKA were quadratic. The optimum EC needed for seedling growth was 2.44-2.60 dS/m. The correlation betweenplant height and number of leaves was very strong as showed by the value at 0.9212. The correlation between BKBA and BKA was strong and this was indicated by the value of 0.7561.

Abstract

This study was conducted in Technical College of Applied Sciences, Sulaimany Polytechnic University, during 2017. Different levels of irrigation were used to production of okra plant. Complete Randomize Design used to layout of the experiment, with three level of irrigation in four replications. Yield, fresh weight of plant, dry weight of plant, yield response factor and different levels of irrigation were observed. The highest yield was given from treatment T1 (3.17 t/ha.) and the lowest was given from T3 (2.988 t/ha.). Also, the maximum fresh weight and dry weight of plant were given from T1 (61.40, 11.218 t/ha.), and their minimum was given from treatment T3 (57.00, 8.783 t/ha.). The highest water use efficiency and harvest index were obtained from T3 (1.615 kg.m-3, 0.095), and the lowest was given from treatment T1 (1.055 kg.m-3, 0.094). The crop response factor and the results in this study showed that the okra plants have a good response of water stress.  As a result, we can recommend cultivating the okra at that time without irrigation in that region.

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.
