Many countries seek to meet the needs of the population for food by increasing domestic productivity as well as by importing it from other countries. Food security is a necessity of a community group and state to ensure that people are satisfied with their food needs. There are four components that must be met to achieve food security, namely the adequacy of food availability, the stability of food supply without fluctuations from season to season or from year to year, accessibility to food, as well as food quality and safety. Researches that lead to these four components have been widely done to improve food productivity and food quality improvement and food security.</p> <p>Research and development of technology in the field of agriculture that supports food security needs to get attention so that these developments can be accessed by all communities. Publishing Journal of Food Security and Agriculture aims to provide opportunities for researchers in the field of food security and agriculture to publish their works to be accessible to the community in need. The quality of this journal will continue to be improved to get a good image in the scientific community. At the beginning of this publication, the articles that are published are the result of the selection and review of articles that have been seminar at the national seminar organized by Udayana University (SENASTEK).</p> <p>It is hoped that the Journal of Food Security and Agriculture can become a reputable scientific publication media that can be useful for the development of science and technology in the field of food security and agriculture.</p>https://ojs.unud.ac.id/index.php/jfsa/article/view/10.24843%2FJFSA.2018.v02.i01.01-05 The Impact of Field School to Increased Revenue for Cocoa Farmers in The Village of Bloro Sub-district of Nita Sikka2020-05-15T12:59:12+00:00Sarlina Noninonisarlina@yahoo.co.id<p><span class="fontstyle0">Field school in Sikka implemented by communities and social institutions Department of agriculture Sikka.

This title must always be maintained. One of the<br>supports that must exist for sustainability is the availability of adequate food, both in quantity and quality. Good quality<br>food is food that is not contaminated or often called organic food. Gianyar regency is one of the regencies in Bali, is one<br>of the tourist destinations visited by many tourists. One of the watersheds in Gianyar regency is Pakerisan watershed. It is<br>a very wide area for agricultural cultivation from upstream to downstream, which is considered as the source of the<br>closest food supply to both the needs of residents and tourists. The dominant crops cultivated in paddy fields are rice and<br>palawija crops. It is expected that food from this cultivation is organic food. The occurrence of pollution in crops can be<br>caused by the use of chemical fertilizers, pesticides and also as a result of waste disposal to the river. The residue of<br>chemical fertilizers, pesticides and wastes will flow from upstream to downstream, resulting the most potentially polluted<br>water resources are in the downstream area. This study aims to study the potential of water resources for the development<br>of organic farming systems in the downstream area of Pakerisan watershed. This research is a field research and<br>laboratory research. Research indicates that the potential of irrigation water in the downstream area of Pakerisan<br>watershed (Medahan irrigation area), in terms of water availability and heavy metal content, suitable for the development<br>of organic agriculture, however, it is not appropriate in terms of carbonate content.</span></p>2020-05-15T12:11:56+00:00##submission.copyrightStatement##https://ojs.unud.ac.id/index.php/jfsa/article/view/59800 Physicall Quality and Nutrient Content of Corn Straw Silage with Different Fermentation Time2020-05-15T12:59:17+00:00Anak Agung Ayu Sri Trisnadewiaaas_trisnadewi@unud.ac.idI Gusti Lanang Oka Cakraaaas_trisnadewi@unud.ac.idTjokorda Gede Belawa Yadnyaaaas_trisnadewi@unud.ac.id<p><span class="fontstyle0">The study aimed to determine the acidity (pH), physicall quality, and nutrient content of corn straw silage with<br>different time fermentation. The experiments use a completely randomized design (CRD) with four treatments and each<br>treatment was repeated five times, so there are 20 experimental units. The fourth treatments are W1 = 14 days<br>fermentation, W2 = 21 days fermentation, W3 = 28 days fermentation, and W4 = 35 days fermentation. The parameters<br>observed in this study are the acidity, physical quality (fungus, texture, color, aroma) and the nutrient content (dry matter<br>(DM), organic matter (OM), ether extract (EE), crude fiber (CF), crude protein (CP), ash). Results of the experiment<br>showed that the acidity (pH) silage of corn straw silage tended to decrease with the increasing of period fermentation,<br>whereas from the physical of quality: fungus belonging to good criteria; texture, color, and aroma showed good medium<br>values??and showed no significant difference with increasing of fermentation period. There was no significant difference<br>in organic matter, crude fiber, and crude protein until 5 weeks of fermentation period, whereas there was a significant<br>difference in dry matter, crude fat, NFE, and TDN from 21-35 days fermentation. It can be concluded that physically of<br>quality and nutrient content are not significantly different.</span> </p>2020-05-15T12:10:54+00:00##submission.copyrightStatement##https://ojs.unud.ac.id/index.php/jfsa/article/view/10.24843%2FJFSA.2018.v02.i01.22-27 Extraction and Identification of Oligosaccharides in Tabah Bamboo Shoots Flour Extract (Gigantochloa nigrociliata BUSE-KURZ) as Prebiotic Source2020-05-15T12:59:18+00:00Dylla Hanggaeni Dyah Puspaningrumdylla_hanggaeni@yahoo.comNi Luh Utari Sumadewidylla_hanggaeni@yahoo.com<p><span class="fontstyle0">This research aims to explore the potentials of tabah bamboo shoots flour as a source of prebiotics by<br>extracting and identifying its oligosaccharide contents. Extraction was conducted using 70% ethanol solvent, (polar),<br>ethyl acetate (semi-polar), and distilled water. Qualitatively phytochemical analysis was conducted. The isolation of<br>oligosaccharide was conducted using column chromatography, Thin Layer Chromatography (TLC) and High<br>Performance Liquid Chromatography (HPLC). The extraction with 70% ethanol solvent has the highest yield (2.62%),<br>followed by distilled water (1.28%), and ethyl acetate (0.92%). The phytochemical analysis of tabah bamboo shoots flour<br>in 70% ethanol discovers that it contains steroid, tannin, and saponin, which are antibacterial compounds. The<br>purification of the extract of tabah bamboo shoots flour yields two main oligosaccharide components: sucrose (0.l3%)<br>and raffinose (1.47%). The presence of oligosaccharides (sucrose and raffinose) in the extract of tabah bamboo shoots<br>flour indicates that the purification results can be used as prebiotics.</span> </p>2020-05-15T12:09:14+00:00##submission.copyrightStatement##
