AMA, Agricultural Mechanization in Asia, Africa and Latin America (AMA) (issn: 00845841) is a peer reviewed journal first published online after indexing scopus in 1982. AMA is published by Farm Machinery Industrial Research Corp and Shin-Norinsha Co. AMA publishes every subjects of general engineering and agricultural engineering.
AMA, Agricultural Mechanization in Asia, Africa and Latin America (ISSN: 00845841) is a peer-reviewed journal. The journal covers Agricultural and Biological Sciences and all sort of engineering topic. the journal's scopes are in the following fields but not limited to:
The optimum of culture time and concentration of alginate for antimicrobial activity of both potential strain L18 and L8 were carried out for 12h, 24h, 36h, 48h, 60h, 72h, 84h, 96h, 108h and 120h by agar well diffusion method. The cultured broth of two best parameters in the previous experiment was designed as bio-products for application on preservation of sea grapes after harvesting. The effectiveness of those bio- products was expressed in the number of pathogenic bacteria counted. The physiological state of sea grapes was reliably evaluated with a diving pulse-amplitude-modulation fluorometer quantifying the chlorophyll fluorescence parameter of maximum quantum yield of photosystem II (PSII, Fv/Fm). Results showed strain L8 was strongly inhibited against Pseudomonas sp. A1 and Klebsiella variicola S1 after 36h cultivation whereas the strain L18 was most inhibition Pseudomonas sp. A1, Enterobacter sp. T1, Citrobacter freundii A2 after 60h cultivation. The concentration of alginate which was the most effective for antimicrobial activity of L8 was 0.3% and L18 was 0.2%. The bio-products added treatments showed a lower number of pathogenic bacteria from 1000 to 10000 times than those in the control samples. Bio-products treatments had not shown significant differences in total phenolic content and chlorophyll-a. In addition, the data from PSII measurement showed that two treatments L8 plus 0.3% alginate and L18 plus 0.2% alginate yielded much better productivity of PSII than other two control samples. The shelf life of edible seaweed could be increased up to 10 days at room temperature, when it was sprayed with bio-products.
The goat has been taking the places on farmers' needs just recently due to its products, i.e. slurry. It has brought a significant impact on economic advantages for small farmers. Those are due to stakeholders’ involvement in promoting its development. The study was done in Manokwari using the descriptive method by using focus group discussion towards twenty various represented individuals, groups, and mass institutions. The queries discussed concerning the background, resources delivery, inter connectivity among actors using Pearson correlation coefficient and similarity matrix, power, and interest of actor’s delivery of intervention and innovation of actors. The goat farming system in West New Guinea is shaped by related groups, lawyers, privates, and stakeholders rather than shareholders. The actors are important and have a positive effect. The actors have a low direct threat and slight high turn back effect. The four top shared resources consist of access, satisfaction, time, and space. The actors have a willingness to contribute in a long-term period and can sustain their support. However, the power of resources shared is neutral and therefore needs further intervention. The relationship of SNA is showing a relationship of similarity and with a greater positive correlation of each actor due to high interest and high power. The five top intervention for goat farming system is skills, feed materials, policy, funds, and satisfaction. While innovation needed by actors are skills, policy, knowledge, feed materials, and fund.
