Abstract

Garlic (Allium sativum L.) Local Sanur variety is one of garlic varieties which are commonly cultivated inBali. This variety has not been identified, although it has been known having good agronomical, as well as goodmorphological characteristics. The aims of this study were to identify Local Sanur variety has good characteristicsfor cultivated at low land area. This experiment was conducted at Sanur, the eastern region of Denpasar. The seedswere planted on the 5.0 m x 2.5 m garden bed with the plant spacing of 25 cm x 25 cm. There were 15 replications,hence, 15 garden-beds all. Each garden-bed was divided into two parts. The plants on a part side were used asdestructive samples, which were required for the variables of growth analysis, and for determination of the periodof vegetative and bulbing phase. Whereas the plants on the other part were used for the variables of plant growthand yield. The result show that the variety of Local Sanur had specific characteristics as described below: the plantheight ranged 48.9 to 56.7 cm, the leaf number was 5.14 to 6.06; the leaf size were 35.73 to 40.73 cm in length and1.05 to 1.39 cm in width. The bulbing phase was commenced at 49 days after planting; therefore the vegetativeperiod was 49 days. The bulb was harvested at 85 days after planting, indicated the bulbing period of 36 days.The yield was 4.82 to 6.60 tons of dry weight per hectare. It was also identified that the bulb has oval shape (egglike)with white flesh and yellowish white skin. Those characters indicated that Local Sanur Varierty suitable fordeveloping at low land area.

Abstract

The research aims to reveal the trens population growth over the 10 years (2002-2012) inTabanan Regency, as well as their impact on the land conversion of subak as well as otherchanges in environmental and cultural aspects of subak. Research conducted through thestages of data collection and data analysis. The technique of data collection was done bythe library research, observation, and structured interviews with questionnaires and indepthinterviews (depth interview).The data collected was analyzed by descriptivequalitativeand quantitative analysis with the help of cross-tables and analysis of satelliteimagery.Resultsof the study showed, the number of inhabitants of TabananRegency in 2012 reached441.900people, consisting of 220. 002-sex guy men and 221.898 women. The livelihoods ofinhabitants,mostly working in the agricultural sector (110.449people) and plantations(45,326people). Based on analysis conducted, it was revealed that within the last 10 years(2002-2012)population growthreached26,10% or = 2.61% per year.The highest growthoccurredin the district of Kediri 5,76%, then followed by district of  Baturiti 5.13%, Marga4.05%,and district of  Tabanan,3,69%. The lowest population growthoccurredin districtPenebel0.34%, then followed by the district of Kerambitan 0,56% and district of EastSelemadeg0.82%. The population growth seems to be more of a factor caused by migration(peoplecoming) 62,24% (1294 inhabitants) (from the difference in population that comes3293with people out 1999 inhabitants), if compared with population growth naturallyonlyachieve 37,76% (785 inhabitants).Thepopulation growth indirectly affects the occurrence of changes in the environment andcultureof subak. In the past 10 years occurred the shrinking land subak (fields) 672,89 ha,or2.95% of the total area of paddy fields in 2002 (22.842 fare ha). Other environmentaleffects,i.e. reduced water supply and the breakdown in some irrigation farmers, pollutionandthe impact of irrigation channel blockage by garbage plastic and aesthetic degradationofthe environment. Socio-cultural impact of subak, which tendency to the occurrence ofsocialconflict, disruption in the silent  ritual of rice fields (penyepian carik) and theabandonment of cultural heritage (pura subak) due to the occurrence of function fields intohousing and tourism facilities.The protection needs to be done to the environment and subak culture through the populationgrowth control with government policy, the formulation of customary law of subak (awigawig),and improve the welfare of farmers through the development of ecotourism that basedonsubak ecosystem.

Abstract

Land and water resources are important roles to keep the sustainability of food production. However, these resources tend to decrease because of developing infrastructure as well building, road, industry, tourism, property, etc. In two decades, it was predicted that land farm alleviation in Indonesia was about 10,000 ha per year. On the other side, food demand tended to increase because of population growth. Consequently, study has to be done to get some information about land area, irrigation facilities, and crops production. The location of the study on one unit area of irrigation, named Daerah Irigasi (DI) Mambal. This study was conducted by survey and field experiment on rice package technology. Survey method was done by interview and literature study. The field experiment was done by some modified input i.e. younger seedling, minimum dosage of complete fertilizer, and minimum water irrigation. These treatments were compared to farmer’s technology, and the result was analyzed by t test. The result of the study revealed that the land alleviation was 38.17% (4,280 ha to 2,980 ha) in a period of 30 years at DI Mambal and the land alleviation at Subak Sempidi was 26% (135 ha to 99 ha) in a period of 24 years. The supply of irrigation water debit at DI Mambal decreased 15% (from 3,596 l/sec to 3,038 l/sec) in a period of 30 years. On the other hand, the supply of irrigation water debit at Subak Sempidi increased 26% (from 168 l/sec to 212 l/sec) from 2005 to 2008. As a final point, supply of irrigation water debit increased from 1.70 l/sec/ha on 2005 – 2007 to 2.14 l/sec/ha on 2008. Paddy yield on experiment of technology package was 12.39 ton of dry grain harvest and it was 11.47 ton of dry grain harvest by the farmer’s technology. From the result of the study was suggested that technology package have to be done by two or three times of cultivation to identify the stability of each harvest yield.

This research considered to conduct at dry season in Denpasar about 2007 and 2008. Selection method on this research is purporsive random sampling. Evaluation of variance selection line (SMCT-2) compare to parent showed significant different (F= 0,05) of some variables such as total of leafs, plants hight, leafs area, internodes, diameter of stems, position of ears corn, silks period, grains line on ears, ears length, grains weight per plant, weight of 100 grains per plant. Non-significant variance of variables is: length of internode, ears corn diameter, dry weight of raw materials, total of productive ears corn, initial period of tassels. Variances of entire variables of SMCT-2 relatively are lower than parent and SMCT-1 line. The higher variances of SMCT-2 are showed on height of plants (526,30) , leafs area (4011,10), position of ears-corn (205,58), dry weight of raw materials (5641,37), dry weight of ears-corn per plant (188,82), total of grains per plant (4335,26), dry weight of grains per plant (276,58). Coerffient of variance showed that SMCT-2 line, SMCT-1 line and parent less than 20 %. Average of variables to support production SMCT-2 line yields are relatively higher than parent is showed by: length of ears corn (13,20 %), dry weight of ears corn (5,6 %), total of grains per ear-corn (15,23 %), lines number of seeds per ear corn (4,80 %), dry weight of grains per plant (27,61 %), dry weight 100 grains per plant (3,33 %). Dry weight of yield SMCT-2 line was founded 5,02 ton per hectar, which is higher 4,58 % than SMCT-1 (4,8 ton per hectare), and is higher 8,71 % than parent (3,9 ton per hectare), with population 50.000 plants per hectare. This line was relative resistance on drought, show that was devolved to produced new variety for the arids areas.

Abstract

Integration of Remote Sensing Technology And Geographic Information Systems for Estimation of CO2 Updake and Emissions in Denpasar City Rapid economic growth in the Denpasar City has an impact on the rate of population growth. This will lead to increasing land requirements for settlements, infrastructure, and other supporting facilities. Meanwhile, the availability of land for green open space (RTH) will decrease. Several studies show that from year to year the area of ??vegetation cover decreases, and the air temperature in Denpasar City is increasing. Therefore, research to calculate CO2 uptake by urban plants and CO2 emissions from various activities in the city of Denpasar is needed to be done. Estimates of CO2 uptake by plants are carried out using remote sensing technology and GIS. Meanwhile, the calculation of CO2 emissions is carried out by an inventory of CO2 pollutant sources from point sources, areas sources, and mobile sources. The output of this study is a distribution map of CO2 absorption and emissions. From the map it can be seen whether the CO2 emissions of Denpasar City are higher than the ability of existing plants to absorb them. The results showed that the ability of plants in Denpasar as a green open space to absorb CO2 was 235,780.63 tCO2/year, while total emissions from pollutant sources were 862,955,856 tCO2/year. The sources of CO2 emissions include from point source 37,649 tons/year, from source area 95,310 tons/year, and from mobile sources at 862,955,856 tons/year. From the movable source the biggest contributor to CO2 emissions is light vehicles, which amounted to 540,355.88 tons/year (62.63%), then followed by motorcycles at 260,187.43 tons/year (30.16%). The amount of CO2 emissions in Denpasar City is 3.66 times greater than the ability of plants to absorb CO2 in 2015 and there is a tendency for this gap to be even greater in the future. To overcome this problem, regulations are needed such as reducing the number of motorized vehicles by increasing public transportation services. The use of vehicles using energy sources other than fuel such as electricity is another alternative to consider. Finally, the increase in the number and quality of green open spaces is a conventional method that needs to be done.

Abstract

ABSTRACT Influence of Plastic Mulch on Crop Chili Pepper (Capsicum frutescens L.) Off  Season in the Kerta village. Chili is one of the important horticultural commodities in Indonesia and has a high economic value. To maintain its supplies, cultivation technology that able to produce the commodities continuously is needed by applying technology in the off-season cultivation. This study aims to determine the effect of plastic mulch on chili crop in the off-season. The experimental design was used a randomized block design with 3 treatments and 9 replications. The treatment given is the use of mulch consisting of silver plastic mulch (MP), black plastic mulch (MH), and without mulch/control (K). The variables observed in this study, ware, plant height, number of branches, soil temperature, symptoms of viral diseases, and yield per hectare. The results showed the plastic mulch give good results on chili crop in the off-season. However, the highest results of the chili plants was in the silver plastic mulch treatments with plant height (95.64 cm), number of branches (13.11 piece), and yield (12.31 ton/ha).   Keywords: chili pepper, off season, plastic mulch, yield

Abstract

The Effects Of Pre-Cooling and Controlled Temperature On The Crop Quality Of Post-Harvested Gonda (Sphenoclea Zeylanica Gaertn) The Gonda plant (Sphenoclea zeylanica Gaertn) is highly prized by the Balinese people, and so, is always readily available, and can be found in both Traditional Balinese markets and modern supermarkets. The Gonda leaf has high-nutritional value, and is widely consumed for this quality. The farming community hasn’t adapted better post-harvesting treatments to maintain the produce’s qualities. What is needed is a treatment-system that consistently maintains the harvested Gonda at different temperatures (pre-cooling). This study aims to determine the effects of pre-cooling and temperature on post-harvested Gonda stores. This research was conducted by Pacsapanen Technology Laboratory, Faculty of Agriculture, University of Udayana. The study applied the Randomized Block Method (RAK), which consists of: P0, P1 through a combination of: S1, S2, and S3.There were 6 combinations of treatments that were repeated 4 times. The results show that the effects of pre-cooling combined with temperature treatment are the least statistically significant (P ? 0,05) on all observed variables. Pre-cooling (P) alone had significant impact on variables (P> 0.05), affecting chlorophyll, weight loss, shelf life, and CO2 respiration rate (ml / g / h), while temperature treatment alone also significantly affected chlorophyll, weight loss, shelf life, and O2 respiration rate variables (ml / g / h). We conclude that low-temperature storage (7C-10C) is the most effective method to maintain the quality of post-harvested Gonda.
