Mahidol University Library and Knowledge Center, 2002) Dujdao Komonweerakate; Panya Kaimuk; Prasert ChatwachirawongPublication Metadata only The Golden Sugarcane: A math game on Android(2014-01-01) Suphawat Chungthanacharoenlert; Navaporn Chockwanich; Kunjira Pasuralertsakul; Chanon Sukklam; Vasaka Visoottiviseth; Mahidol University© 2014 IEEE. "The Golden Sugarcane" is a mathematical game developed by Java and implemented on Android operating system. The game focuses on amusement and challenges. Within the game, a player needs to prepare his elephant by solving mathematical... will gain advantages in the duel. Ranking system will help players to evaluate and improve themselves over time. In addition, the player can post his progress on Facebook. Scores will be kept in a database on a server to determine the rank and the levelPublication Open Access Comparative analysis of sugarcane bagasse metagenome reveals unique and conserved biomass-degrading enzymes among lignocellulolytic microbial communities(2015) Wuttichai Mhuantong; Varodom Charoensawan; Pattanop Kanokratana; Sithichoke Tangphatsornruang; Verawat Champreda; Mahidol University. Faculty of Science. Department of BiochemistryBackground: As one of the most abundant agricultural wastes, sugarcane bagasse is largely under-exploited, but it possesses a great potential for the biofuel, fermentation, and cellulosic biorefinery industries. It also provides a unique... for the discovery and characterization of new biomass-degrading enzymes; however, it remains largely unexplored. Results: We have constructed a fosmid library of sugarcane bagasse and obtained the largest bagasse metagenome to date. A taxonomic classificationPublication Open Access The estimation of Carbon storages in various growth stages of sugarcane in Si Sat Chanalai District, Sukhothai Province, Thailand(2009-12) Wachirawan Watcharapirak; Sura Pattanakiat; Charlie Navanugraha; Mahidol University. Faculty of Environment and Natural Resource StudiesThe objectives of this research was to estimate carbon storage in sugarcane plantation in Si satchanalai district, Sukhothai province in one crop yield. The various growth stages of sugarcane were studied at aboveground and belowground.... In addition, carbon storage in soil was studied in upper soil horizon. The carbon storage of the sugarcane plantation was analyzed both in plant and soil. The carbon storage in plant was estimated from biomass and organic carbon percentage in each partPublication Open Access Energy Use and Consumption Patterns of Maize Cultivation - A Case Study in Thailand(2021) Sirikarn Thongmai; Thanakrit Neamhom; Withida Patthanaissaranukool; Supawadee Polprasert; Mahidol University. Faculty of Public Health. Department of Environmental Health Sciences; Mahidol University. Center of Excellence on Environmental Health and Toxicology (EHT)This study explored energy inputs and consumption patterns to determine energy and economical indices for maize cultivation in Thailand. To assess the energy performance of four used cropping systems, namely, highland cultivation in wet season (HLWS), highland cultivation in dry season (HLDS), plains cultivation in wet season (PLWS), and plains cultivation in dry season (PLDS), data from energy consumed and produced show Net Energy Value (NEV) gains of +77.0, +106.5, +191.6, and +228.5 GJ/ha, respectively. Positive signs indicate that the required energy was less than energy produced which reveals sustainability. Use of fertilizer accounted for the major input energy in all systems, followed by fossil fuels, human labor and seeds. A cost performance analysis demonstrated PLDS production exhibited the highest profit earnings (1,365.2 USD/ha). To establish an alternative way to reduce the amount of energy consumed together with increased profit returns to farmers, the renewable energy from waste manure was used to replace dependence on chemical fertilizers. Scenarios using manure from cows, chickens, and farmyards were considered. Results showed that the use of farmyard manure created greater amounts of energy efficiency and economical return rates. Moreover, the benefits increased with increased amounts of organic material applied.Publication Open Access Comparison of Carbon Footprint of Organic and Conventional Farming of Chinese Kale(2019) Monthira Yuttitham; Mahidol University. Faculty of Environment and Resource StudiesThis study compared the carbon footprint (CF) of organic agriculture with that of conventional agriculture in the cultivation of Chinese kale. The farm management data collected included the use of chemical and organic fertilizers, and fossil fuel for tillage, irrigation and transportation. Greenhouse gas emissions (GHG) were calculated and added to the CF. The results showed that conventional agriculture had a CF of 0.402±0.47 kg CO2e/kg Chinese kale. Proportion of CFs from: chemical fertilizer (51%), transportation (21%), irrigation (19%), tillage (5%), organic fertilizer (2%), herbicide (1%) and insecticide (1%), and organic agriculture had a CF of 0.195±0.122 kg carbon dioxide CO2e/kg Chinese kale (proportion of CFs from: transportation (81%) organic fertilizer (12%) and fossil fuel for irrigation (7%). The CFs differed, depending on farm management, and that of conventional agriculture was almost double that of organic agriculture because of the higher emissions from use of chemical fertilizers and of fossil fuel for tillage, herbicide and insecticide applications. The conventional farm management led to higher production per unit of planted area. Thus, it seems that conventional farming has relatively higher CF than organic farming. There is still room for both management practices to reduce their GHG emissions and their CFs by reduce chemical fertilizer and fossil fuel use in conventional farming. The promotion of organic farming practices will help to improve sustainable, environmentally friendly agricultural production of Chinese kale in Thailand.
