	abstract = {Agriculture is a sector with strategic and crucial sectors for Indonesia in developing its economic structure. It accounts for 43\% of total employment and directly contributes 15\% to the Gross Domestic Product (GDP). In 2012, the national production of vegetables which comes from local farmers in Indonesia reached 11.6 million tons and increases to 41.8\% each year. The diversity of agricultural products in Indonesia is an advantage, but the lack of ability to maintain the quality is a big loss for Indonesia. Food and Agriculture Organization of United Nations estimates that one-quarter to one-third of world vegetables are lost due to pests, insects, bacteria, fungi and enzymes which degrade the quality of vegetables. It is caused by the poor handling process after harvesting by conventional methods. This loss is very detrimental for Indonesia farmers because their vegetable will not be bought by people then will decrease economic benefits of farmers and it is also able threaten the national food security. Improvement of the vegetables quality production is needed as a preparation for Indonesia to face Association of Southeast Asian Nations Economic Community competitively. Development of nuclear irradiation technology by using Gamma rays emitted by Co-60 at low dose can be used as a new alternative to improve the quality preserving vegetables by delaying germination and killing insects, pests and microbes. With the right dose of radiation, it will inhibit sprouting, delay ripening, and killing parasites without affecting the nutritional value of the vegetables. Irradiation method, compared to conventional postharvest handling method has several advantages as it does not leave any residue, give longer shelf-life, and more environmental friendly. This irradiation prevent damage of vegetables to fulfill the national demand, increase farmers economic, improve food security, and prepare Indonesia to face the ASEAN Economic Community competitive era.},

	abstract = {An experiment has been conducted to know bacteria diversity in domestic buffalo meat and bowel from Pandeglang Banten traditional market in order to ascertain its safety based on its initial contamination. The total bacterial was assessed by total plate count method as index of quality. The buffalo meat and bowel samples were taken from liver, intestine, lymph, lung and tripe. Results showed that the contaminated bacterial were aerobic bacteria, coliform, Escherichia coli, and Staphylococcus spp. in buffalo meat and bowel. The amount of aerobic bacteria was in the range 1.7 x 105 up to 2.3 x 106 CFU/g(colony-forming units per gram), while total coliform bacteria was in the range 2.0 x 103 up to 6.8 x 104 CFU/g. Total number of E. coli was in the range 2.0 x 103 up to 6.0 x 104 CFU/g and for Staphylococcus, spp. was in the range 2.0 x 104 up to 2.7 x 105 CFU/g. No Salmonella was detected in all samples observed. The total coliform bacteria, E. coli and Staphylococcus, spp in all buffalo meat and bowel samples have exceeded the standard microbial number from the Indonesia National Standard (SNI). It is necessary to further evaluate the quality assurance and security management. Proper sanitation and hygiene in slaughter house must be achieved to minimize pathogenic bacteria contamination and improve domestic meat quality. Improvement of the quality is needed to shelter meat domestic production from import competition, as a preparation for Indonesia to achieve Indonesia beef self-sufficiency in 2014.},
