Abstract

Goverment of Klungkung Regency, Bali province has a plan to develop an ecotourism area at Bukit Abah. The area is located within Besan Village, District of Dawan. In associated with this plan, a study has been conducted to identify the availability of diversity of flora in this site. The study was conducted by plant type stocktaking and analysis of vegetation methods. Results of plant type stocktaking shown that there were 126 plant species in the area, which were classified into 54 families. In addition, the analysis of vegetation indicated that there were a wide diversity of plants identified in Bukit Abah, with a diversity index (H) of >1.5. The high diversity of flora on the site had made a potential of attractive attention for developing of ecotourism in this area. It is suggested to accomplish an informative plantation labeling and vegetation conservation in associated with the development of the ecotourism plan

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.

Abstract

The research entitled “ Developping drought resistance of corn variety via evaluation of SMCT-2 line ” which aimed to achieve of agronomic characteristic varians and yield potential of SMCT-2 compare with SMCT-1 line and their parent. 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

The purposes of the research are to know the composition, distribution, and dominantspecies of vegetation at Batukaru forest conservation area (RTK-4). This research usedtransect method done by systematic plot sampling. Five transects were made, that was thedistance of 1 km each transect line. In each transect line there were 10 plots with the dictanceof 100 m each plot.The result of the experiment found 33 kinds of higher plant to cover the field on Gesingvillage and 18 kinds on Bukit Catu village, with Podocarpus imbricatus Blume is thedominant species on the both villages, with each the important value index of 88,82 % and99,47 % for the higher plant, so that species not stable yet. The lower vegetations thatidentificated on each location are 27 and 34 kinds of speciesDiversity Index on some level of plant growth at Gesing and Bukit Catu villages arearound 1,88 (sedling) – 2,77 (tree) and 1,77 (sedling) – 2,11 (tree), so the communitycondition is in the term of stable.
