    Fuel Briquette Potential of Lantana Camara L. Weed Species and its Implication for Weed Management and Recovery of Renewable Energy Source, in Ethiopia
    (Addis Ababa University, 2015-09) Sintayehu Abebe; Seyoum Leta
    This study aimed to produce fuel briquettes and weed management in ecofriendly manner from Lantana camara, which is most serious invasive weed, spreading throughout the world particularly at alarming rate in Ethiopia. Utilization of biomass like invasive weed such as lantana camara L. species in Ethiopia have greater advantage for discovery of clean renewable energy sources and for reduction of deforestation of indigenous trees. Producing and evaluation of the fuel briquetting potential of root, stem, branch and leaves and the charcoal potential of root, stem,and branch of Lantana camara L. weed species were carried out by using ASTM procedure. The mean average value for fixed carbon content(FCC) and calorific value of the root, stem ,branch and leaves fuel briquette of Lantana camara L sample were:53.89±1.84(%)and6525.54±250.03(cal/gm); 52.77±0.39% and 6479.59± 1004.51(cal/gm );50.22 ± 3.21(%) and 5135.36± 150.29 (cal/gm); 37.56 ± 0.69 (%) and 3690.67 ± 182.32 (Cal/gm); respectively. The result for fixed carbon content(FCC) and calorific value of the root, stem and branch of charcoal produced Lantana camara L sample were:65.6(%)and 7483.99(Cal/gm);6.44(%) and 7483.99(Cal/gm);64.89(%) and 7222.66(Cal/gm);respectivelyThe finding show that by ecofriendly utilization of lantana camara weed as a clean energy fuel briquette. it‟s possible to manage the spread of such type alien invasive weed as well as to increase farmers crop production, access for livestock grazing land;reduce deforestation of indigenous trees and reduce indoor air pollution.

    The opportunities and challenges of lease Financing in Development Bank of Ethiopia
    (Addis Ababa University, 2019-06) Sintayehu Abebe; Habtamu Berhanu
    The main objective of this paper is to assess the overall opportunities and challenges of lease financing service in development Bank of Ethiopia. Leasing is financing in kind and DBE has been providing lease financing service in the form of supplying capital goods to small and medium enterprises since 2016. The research approach adopted in this study was a mix of quantitative and qualitative approaches. Both primary and secondary data were used. In identifying the respondents from the study population, purposive sampling was adopted. All District offices of the Bank and selected work units from Head office were included in the sample. The study identified opportunities of lease financing and got high level of agreement by respondents. The level of agreement on opportunities questions responded as lease business sector, strong support from the government, leasing business opportunity for employment creation, new investment opportunity and contributing for SMEs development. The study also found out that the major internal and external challenges of the lease financing in DBE are high lease NPLs, tight lease requirements, lack of hard currency, inadequate MIS, policy and procedure amendments repeatedly, and lack of capital. Based on the survey and interview results the researcher forwarded its conclusion and recommendation.
