Abstract

Database of Sustainable Food Agricultural Land Resources Based on Remote Sensing and Geographical Information System at Subak Temaga East Denpasar Subdistricts. Subak Temaga doesn’t yet have a database according to Government Regulation No. 25 of 2012 concerning Information System for Sustainable Food Agriculture Land (SFAL). A geospatial-based database needs to be compiled to implement these regulation. The research aims: compile a database of artificial resources, agricultural resources, land resources and human resources to support SFAL in Subak Temaga, create land ownership maps in Subak Temaga, compile an information system of SFAL and land ownership based on remote sensing and Geographic Information System (GIS). This research uses a survey method to obtain primary data, then doing the mapping to compile the information system based on geospatial. The research results: artificial resources (irrigation, jogging track/farm road), land resources (soil family, landform, slope, rainfall, land suitability, soil fertility), agricultural resources (types of farm commodities, productivity, agriculture tools and machinery, cropping pattern, types and dosage of fertilizer), human resources (name, address, age, last education, farmer status, ownership status, ownership large and boundary, profit-sharing system). Farmer status consists of 56 owner farmers (30,9%) and 125 sharecropers (69,1%). Land ownership status consist of 432 freehold polygons (92,7%) and 34 non freehold polygons (23.8%). Remote sensing is used to determine the boundaries of land ownership, GIS is used to compile a geospatial-based information system for LP2B and land ownership.

Abstract

Differences in Height, Number of Leaves, and Stem Diameter of Corn (Zea mays L.) in Alley Cropping and Intercropping of Agroforestry Systems at the Micro Watershed of Tukad Sumaga Village, Gerokgak District, Buleleng Regency. Degraded land as a result of land conversion has a very bad impact on the agro-ecosystem. Land conversion caused by the increasing needs of the population. The majority of the livelihoods of the people in Tukad Sumaga village are farmers. The availability of forage is very important to be maintained. Corn plants, in addition to their production in the form of corn, forage fodder on corn plants are very important for the availability of cattle feed. This research was conducted on 28 DAP maize (Zea mays L.) in alley cropping system and intercropping in the micro watershed of Tukad Sumaga Village. The results showed that the highest average plant height, leaf number, and corn stalk diameter were found in the alley cropping system namely 1.03 m, 7.31, and 1.59 cm. There was no significant difference between the height of corn plants in alley cropping and intercropping systems. There is a significant difference between the number of leaves and the diameter of the stems of maize in alley cropping and intercropping systems.

Abstract

The Effect of the Mount Agung Volcanic Ash and Compost on Soil Properties and Yield of Tunggak Nuts (Vigna unguiculata (L.) Walp). The purpose of this study was to determine the effect of giving volcanic ash and compost as a soil amendment. The design used was a factorial randomized block design. The volcanic ash factor consisted of 3 levels: A0 = no volcanic ash, A1 = 15% volcanic ash and A2 = 30% volcanic ash. The compost factor consisted of 3 levels: K0 = without compost, K1 = 10 tons of compost ha-1, and K2 = 20 tons of compost ha-1. The combination treatments was repeated 3 times so that there were 27 observation units. Several parameters of soil properties and yield of tunggak nuts were studied to determine the effect of volcanic ash and compost as soil amendments. The results showed that the interaction between the treatment of volcanic ash and compost on the soil and plants was not significant, while the single treatment of compost had a significant effect on the growth and yield of tunggak nuts. The treatment of volcanic ash has not shown a significant effect, both on soil and on plant growth and yield.

Abstract

The Utilization of Biochar as a Carrier of Rhizobium for the formation of root nodules and Yield of Soybean (Glycine max L. Merril). This study aims to determine the effect of the type of raw materials and particle size of biochar as a Rhizobium carrier on the formation of nodules in soybean plants. This research was conducted from September to November 2020 at the Experimental Station and Laboratory of Soil and Environmental Sciences, Faculty of Agriculture, Udayana University. The research design used was a randomized block design with nested patterns with 2 factorials and 3 replications. The treatment factors consisted of B1 = bamboo biochar, B2 = albasia wood biochar, B3 = corncob biochar, B4 = young coconut skin biochar, P1 = (0,15-0,50 mm), P2 = (>0,50-1,68 mm), P3 = (>1,68-3,36 mm). The parameters observed included effective nodule, nodule size, total bacterial population, ammonium, nitrate, and plant yield. The result of the analysis showed that the type of biochar raw materials had a very significant effect on the parameters of effective nodules, nodules size, total bacterial population and plant yield, but had no significant effect on soil chemical parameters. The treatment of biochar particle size had a very significant effect on the parameters of effective nodules, total bacterial population, and plant yield, and had a significant effect on the size of nodules, but had no significant effect on soil chemical parameters. The conclusion of this study is that the type of raw material for albasia wood biochar is effective as a Rhizobium carrier, which is indicated by the high number of effective nodules, nodules size and total bacterial population of 0,15-1,68 mm particles.

Abstract

Strategy For Improving Effectiveness of Fire Care Society (MPA) in Control of Forest Fire in Bali Province. Land and forest fires seem to be an annual disaster in Indonesia. The Ministry of Environment and Forestry is initiated to form Fire Care Community Groups, called Fire Care Society (MPA). MPA in Bali has been established since 2012. The study is needed to determine the community perception who live around the forest areas, to determine the effectiveness of MPA, and to analyzed strategic increases the effectiveness of MPAregarding forest fires controlling. Research data has been collected through a closed questionnaire to compile the respond of respondents in the google form. The respondent consisted of MPA member and non-member and related stakeholders. The types of data that been collected include respondent’s perceptions, MPA participation, and implementation of Perdirjen PPI number 3, 2018. These data then analyzed with the SWOT method. The results showed that the MPA and non-MPA members have positive perception of natural factor and human behavior as a factor of forest fires. The highest value of MPA’s participation in fires-fighting is 3.71 and participation influenced by environmental factors valued at 3.84. While the implementation of Perdirjen PPI decree is 66.39%. The SWOT analysis shows the MPA in progressive strategic S-O. So this study concludes that the MPA hasn’t been fully effective. The effectiveness can be improved by providing adequate support through clear regulations, budget allocations, and increasing human resource capacity.
