REMOVAL OF FLOURIDE FROM GROUND WATER BY SURFACE MODIFICATION OF RED SOIL ON THE POLYANILINE: ACASE OF MAREKO SPEACIAL WOREDA, ETHIOPIA
(wolkite universty, 2024-08) KORU JEBENO DUTEBO
Surface modification of natural adsorbents for enhanced adsorption of water pollutants is strategy developed by varieties of research groups. The purpose of this study was to analyses physicochemical properties and to develop adsorbent material by modifying the electronic structure of red soil via facile in situ chemical oxidative polymerization techniques to remove fluoride from groundwater. The as-synthesized materials were also characterized using powder xiiXRD, FT-IR, UV- Vis spectroscopy, and Conduct meter, and their adsorption performance was tested. The XRD studies reveal that the crystal structures of embedded red soil were amorphous, while PANI, PANI/red soil nano particles distorted and become polycrystalline. The maximum adsorption capacity (qmax) of fluoride ions by PANI/RS was 9.35mg/g. The maximum adsorption performance of PANI/RS at different optimization parameter fluoride ions at pH 4.0, contact time for the adsorption process was 50 minutes, temperature was 350c, initial concentration15mg/L with 2mg adsorbent is 99.9%. Both Langmuir and Freundlich isotherm data for fluoride have a good fit with the experimental data (R2 = 0.94 and 0.95), respectively. Therefore, PANI/RS is remarkably outperformed red soil can be a promising candidate to be used as and sorbent material to remove fluoride ions from groundwater
VALUE CHAIN ANALYSIS OF POTATO IN GURAGE ZONE IN CASE OF GUMMER WOREDA
(wolkite universty, 2022-05) TESHOME BEGASHAW
This study explores the value chain analysis of potato in SNNPR, Guraghe Zone;Gummer District. The data were collected from both primary and secondary sources. The primary data were collected from individual interview using semi-structured questionnaire and key informants interviews by using guiding questionnaire. The primary data for this study were collected from 154 randomly selected potato producer households. Data analysis was made using descriptive statistics and multiple linear regression models. The potato products pass through different marketing agents before reaching the end users. The result of the multiple linear regression models indicates production surplus of potato was significantly affected by distance to all weather roads, number of livestock, potato land size, irrigation access, credit access, cash income from other farm activities and lagged price. And also it revealed that the main receivers ofpotato from producers were wholesalers, collectors and consumers. The major constraints and opportunities were at different stages of the value chain. Potato is widely grown and marketed for a long time in the study area, yet farmers face Diseases anapests, Limited access to supply of agricultural inputs and Natural factors are significant and this three variables were constrain of potato production. The opportunities were suitable agro-ecology and government support. Strengthening the linkage among actors, providing training on storage construction and disease control, improving bargaining power of producers and initiate small scale processors were recommended to improve potato value chain.
Effects of Credit Risk Management on the Performance of Microfinance Institutions: In The Case of Gurage Zone
(wolkite universty, 2024-05) Tadele Gebre
The aim of this study was to investigate the effect of credit risk management on the performance of MFIs in the case of Gurage Zone, Central Ethiopia Region. The study employed descriptive survey and explanatory research design along with quantitative approach. The target population of the study was all employees in the six MFIs found inGurage Zone. 84 employees were the sample of the study. Purposive, proportionate stratified, and simple random sampling techniques were used to select MFIs, administrative towns andworedas and employees. Primary data were collected using self – administered questionnaires for employees of the selected MFIs. Descriptive statistics, correlation coefficient analysis, multiple linear regression analysis were used to analyze the quantitative data and to investigate the effect of credit policies, credit administration unit, top management support, credit assessment, credit monitoring, and debt collection practices on the performance of MFIs. All quantitative data were analyzed using a Statistical Package for Social Sciences (SPSS) version 26. The findings of the study revealed that all the five credit risk management practices have significant and positive effect on the performance MFIs, butdebt collection practice has no significant effect. However, 79.7% of the variations in the performance of MFIs were jointly accounted by the six variables, among these variables; top management support practice has the greatest contribution. Therefore, the performance ofMFIs in most of the administrative towns and words becomes stagnant, unless these credit risk management practices are appropriately pledged. Thus, this study suggests that management bodies of the MFIs in the zone better to give more emphasis by focusing robust credit risk management practices, so that MFIs can improve their performance and contribute to the broader economic development of the study area. Moreover, continuous evaluation and adaptation of these practices will be essential to navigating the dynamic financial landscape.
THE PRACTICE AND CHALLENGES OF FISCAL DECENTRALIZATION, A CASE STUDY OF GUBERE SUB CITY IN WOLKITE CITY ADMINISTRATION.
(wolkite universty, 2022-09) FELEKE ABATE GRAGN
Fiscal decentralization is look as part of a reform agenda in developing countries to Empowered regional and local governments. It is believed that it betterments the efficiency of public service Delivery through preference deserting and allocation efficiency. According to this idea, this study was conducted to assess the practice and challenges of gubere sub city fiscal decentralization in wolkite City administration. In doing this study, mixed method research design was followed. Subjects of the study were householders and government officials working in gubere sub-city of wolkite city administration. In the study, multi-stage sampling technique was used to select representative respondents. To this effect, one hundred ninety-six participants were selected using multi-stage sampling technique. Besides, sub-city Leadership members, revenue and Finance officials to conduct key informant interviews and again focus group discussion participants were purposely selected. The data gathering instruments were questionnaire, key informant interviews and focus group discussion, and document analysis. Data collected from the survey was analyzed using descriptive statistical techniques. The data were analyzed using software Statistical Package for Social Science (SPSS V.20). The findings indicates that respondents’ responses concerning autonomy of gubere sub city is not planning budget, not uses own revenue and grants nothing to expenditure assignments. This implies that there is absence of the fiscal decentralization practices. And again the functionalities of institutional and legal frameworks, inter-governmental fiscal relations, challenges, and constraints of fiscal decentralization, were significantly different. In general, the practice of fiscal decentralization in the gubere sub city was nothing as existing institutional and legal frameworks. Respondents stated that gubere sub city administrations had enough revenue base, but not using autonomy and not planning and budgeting, revenue using and expenditure assignment autonomy. Based on the findings of the study, the research hence recommended that existing institutional and legal frameworks are basic issues, so needed to structured fastly. in the other hand that it enables to gubere sub city administrations to generate and utilize sufficient revenues, plan and budget own activities, autonomy of expenditure assignments are please hurry up to practice. Inter-governmental fiscal relations vertical imbalances are better to fix fastly in sub city Administration level.
