Authors:Sarlina Noni Pages: 01 - 05 Abstract: Field school in Sikka implemented by communities and social institutions Department of agriculture Sikka. Bloro village is one of the villages which have been carrying out the program of the school field.The main target field school in the village of Bloro is a cocoa farmer the farmers groups. Activities and field school subject matter include: cocoa P3S (Pruning, Fertilizing, Harvesting and sanitation Rehabilitation), pests and diseases and how to cope with it and management of nursery. The purpose of this research is to know the impact of the field school in increasing revenue for cocoa farmers in the village of Bloro, Nita, Sikka. Methods of analysis used in this study is qualitative and quantitative methods. Research results, a simple linear regression analysis note that the magnitude of the value of t test = 4.342; While the magnitude of significance = 0.000 smaller than 0.05 so Ho denied that means there is a significant influence of the variable field school against a variable increase in revenue with a regresinya equation is Y = 6.108 + 0, 501X. From the regression equation is then to be drawn the conclusion that when the school field is increased of one-unit then there is an increase in revenues of 6.609. Correlation analysis of product moment may note that there is a strong influence among the field school to increased revenue of 0,707. Based on the results of the analysis of determination coefficients obtained determination (CD) of 49.98%, while other influential factors significantly outside the research variables are of 50.02%.

Authors:I Wayan Narka, I Nengah Dibia Pages: 06 - 08 Abstract: Experiments to study the effect of organic, anorganic fertilizer and nitrobacter biofertilizer on Relative Agronomic Effectiveness, R A E was carried out in the glasshouse Faculty of Agriculture Udayana University. This experiment was set up in Randomized Block Design with t h e c o m b i n a t i o n s o f organic, anorganic fertilizer, and biofertilizer as research factor. This factor consisted of 8 levels. P0 : without fertilizer P1 : organic fertilizer P2 : anorganic fertilizer, P3 : biofertilizer, P4 : P1+P2, P5 :P1+P3, P6: P2+P3, and P7: P1+P2+P3. R e la t iv e A g r o n o mic E f f e c t iv e n e s s w a s observed base on the dry weight of the green mustard plant. The results of the experiment showed R e la t iv e A g r o n o mic E f f e c t iv e n e s s higher than 100% is achieved in the treatment of P3, P5, P6, and P7 is about 268.86 %; 213.77 %; 208.15 %; dan 35.42 % respectively.

Authors:Netera Subadiyasa, Indayati Lanya, Nyoman Dibia Pages: 09 - 14 Abstract: Competency-Based Research Program (KBR), the purpose of improving the competence of lecturers in the field. Referring to the Master Plan of Research (MPR) of Udayana University, the field of food security. Its goal of producing appropriate technology to improve the production and quality of horticultural crops, as well as environmentally friendly agriculture is required for hotel and restaurant needs. Baliplus Mineral Fertilizer (BMF) Treatment Test = (5 tons dolomite + 100 kg NPK) ha-1 in Andosol soil, sandy. Five plants were tested: broccoli, cauliflower, round salad, pinach, and mustard tope. Randomized block design, treatment of fertilizer per hectare: P0 = organic fertilizer = 20 tonnes, P1 (fertilizer farmers) = P0 + 200 kg NPK, P2 = 400 kg NPK, P3 = ½ P0 + 1BMF, and P4 = ½P0 + 2BMF. Three replications, observation parameters: production, increased production, and nutrient content of the plant. Duncan's real test difference of 5%, using the Costat program. BMF has a very significant effect on chlorophyll and significantly increases the production of all tested plants, P4 treatment obtained the highest production and percentage increase compared to farmer fertilizer. Production and percentage of increase: broccoli 15.89 tons ha-1 (16.78%), cauliflower 20.02 tons ha-1 (13.62%), round salad 32.37 tons ha-1 (26.36%), spinach 21tons ha-1 (16.21%), and mustard tope 23 tons ha-1 (13.13%), BMF increases the nutritional content: total sugar, carbohydrates, fiber, vitamin C, and antioxidants. Quality broccoli > cauliflowers > round salad. BMF increases production, and product quality, and reduces the use of organic fertilizers. PubDate: 2020-05-15 Issue No:Vol. 2, No. 1 (2020)
Authors:I Gusti Ngurah Santosa, I Wayan Budiasa Pages: 15 - 21 Abstract: Bali is known as one of the world's tourism destinations. This title must always be maintained. One of the supports that must exist for sustainability is the availability of adequate food, both in quantity and quality. Good quality food is food that is not contaminated or often called organic food. Gianyar regency is one of the regencies in Bali, is one of the tourist destinations visited by many tourists. One of the watersheds in Gianyar regency is Pakerisan watershed. It is a very wide area for agricultural cultivation from upstream to downstream, which is considered as the source of the closest food supply to both the needs of residents and tourists. The dominant crops cultivated in paddy fields are rice and palawija crops. It is expected that food from this cultivation is organic food. The occurrence of pollution in crops can be caused by the use of chemical fertilizers, pesticides and also as a result of waste disposal to the river. The residue of chemical fertilizers, pesticides and wastes will flow from upstream to downstream, resulting the most potentially polluted water resources are in the downstream area. This study aims to study the potential of water resources for the development of organic farming systems in the downstream area of Pakerisan watershed. This research is a field research and laboratory research. Research indicates that the potential of irrigation water in the downstream area of Pakerisan watershed (Medahan irrigation area), in terms of water availability and heavy metal content, suitable for the development of organic agriculture, however, it is not appropriate in terms of carbonate content.

Authors:Anak Agung Ayu Sri Trisnadewi, I Gusti Lanang Oka Cakra, Tjokorda Gede Belawa Yadnya Pages: 22 - 27 Abstract: The study aimed to determine the acidity (pH), physicall quality, and nutrient content of corn straw silage with different time fermentation. The experiments use a completely randomized design (CRD) with four treatments and each treatment was repeated five times, so there are 20 experimental units. The fourth treatments are W1 = 14 days fermentation, W2 = 21 days fermentation, W3 = 28 days fermentation, and W4 = 35 days fermentation. The parameters observed in this study are the acidity, physical quality (fungus, texture, color, aroma) and the nutrient content (dry matter (DM), organic matter (OM), ether extract (EE), crude fiber (CF), crude protein (CP), ash). Results of the experiment showed that the acidity (pH) silage of corn straw silage tended to decrease with the increasing of period fermentation, whereas from the physical of quality: fungus belonging to good criteria; texture, color, and aroma showed good medium values''and showed no significant difference with increasing of fermentation period. There was no significant difference in organic matter, crude fiber, and crude protein until 5 weeks of fermentation period, whereas there was a significant difference in dry matter, crude fat, NFE, and TDN from 21-35 days fermentation. It can be concluded that physically of quality and nutrient content are not significantly different. PubDate: 2020-05-15 Issue No:Vol. 2, No. 1 (2020)
Authors:Dylla Hanggaeni Dyah Puspaningrum, Ni Luh Utari Sumadewi Pages: 28 - 33 Abstract: This research aims to explore the potentials of tabah bamboo shoots flour as a source of prebiotics by extracting and identifying its oligosaccharide contents. Extraction was conducted using 70% ethanol solvent, (polar), ethyl acetate (semi-polar), and distilled water. Qualitatively phytochemical analysis was conducted. The isolation of oligosaccharide was conducted using column chromatography, Thin Layer Chromatography (TLC) and High Performance Liquid Chromatography (HPLC). The extraction with 70% ethanol solvent has the highest yield (2.62%), followed by distilled water (1.28%), and ethyl acetate (0.92%). The phytochemical analysis of tabah bamboo shoots flour in 70% ethanol discovers that it contains steroid, tannin, and saponin, which are antibacterial compounds. The purification of the extract of tabah bamboo shoots flour yields two main oligosaccharide components: sucrose (0.l3%) and raffinose (1.47%). The presence of oligosaccharides (sucrose and raffinose) in the extract of tabah bamboo shoots flour indicates that the purification results can be used as prebiotics.
