    Accessing agricultural information by rural farmers through mobile phones in Karaye Local Government Area of Kano State, Nigeria
    (Journal of ICT Development, Applications and Research, 2021-04) Alhassan, Yahaya Karaye; Mohammed, Zakari; Ibrahim, Hassan Mallam
    This study investigated access to agricultural information by rural farmers through mobile phones in Karaye Local Government Area of Kano State, Nigeria. The objectives of the study include: ascertaining how the rural farmers access agricultural information through mobile phones in Karaye Local Government Area, Kano State; finding out the sources of accessing agricultural information by rural farmers in Karaye Local Government Area; and determining the challenges that these farmers face in accessing agricultural information through mobile phones. A survey research method was used for the study. The study population comprised 1,279 registered rural farmers, 121 farmers, and three (3) wards were purposively selected as sample. A structured and closed-ended questionnaire was designed and used for the data collection. One hundred and twenty-one (121) copies of the questionnaires were administered to the registered farmers, out of which 95 copies were returned, representing 78%. Data collected were analyzed using descriptive statistics of frequencies and percentages. The findings of the study reveal that rural farmers' significant mean access to agricultural information through mobile phones was short message service (SMS); that most farmers sourced agricultural information from their other farmers (colleagues) through mobile phones; that majority of the rural farmers indicated that the inability to access agricultural information from the formal sources (research institutes, extension workers, researchers) and lack of sufficient and wide mobile phone network coverage in the communities were the challenges being faced. The study recommends that: the Federal Government of Nigeria should through the National Communication Commission (NCC) liaise with telecommunication companies to reduce the rate of call charges so that rural farmers can make direct calls apart from Short Message Service (SMS) to extension workers or any other agricultural stakeholders to access agrarian information easily. Farmers should be sourcing agricultural information from research institutes, researchers, and extension workers apart from their colleagues (other farmers) to access relevant and up-to-date information to help achieve sufficient production and prevent poor harvest. The study concludes that with timely access to relevant agricultural information by rural farmers Nigeria can attain food sufficiency.

    AN APPRAISAL OF HEALTH AND SAFETY TRAINING PRACTICES OF SMALL AND MEDIUM CONSTRUCTION FIRMS
    (2019-08-04) ABUBAKAR, Muawiya DODO, Mansir ZAILANI, Muhammad Bello KAISIH, Ezekiel
    Small and Medium construction firms constitute a large percentage of construction firms in developing countries, who in turn are the highest employers of construction labour. The safety of construction wokers on site is paramount to the overall success of the project as only when workers are in a sound state of mind and are physically healthy that work can go on efficiently. Safety training has been identified as one of the factors influencing safety performance in the construction industry. However, despite the emphasis on the need for effective health and safety practices, poor safety training practices in some segments of the construction industry have been observed by previous studies. This paper therefore, aims to appraise the health and safety training practices of small and medium construction firms in Nigeria. A purposive sampling technique was used to sample the study population. A quantitative research approach was adopted for this study The tool used for data collection was a structured questionnaire which was distributed to safety managers and project managers in small and medium construction firms. Data colected was analysed using descriptive statistics whereby the mean was used as a basis to rank the factors studied. Results from analysis shows that despite these construction firms not having a written health and safety policy, they do actually engage in health and safety trainings. Furthermore, training for non-managers has been found to be given more priority in both small and medium construction firms studied as against training for managers. Training employees on the use of Personal Protective Equipment (PPE)" ranked top amongst the most practiced safety training in both small and medium constructon firms. Small firms ranked PPE training. Orientation for all new hire as well as conducting training for every new job to be executed were both ranked high by small firms but ranked low by medium firms. The paper ultimately adds to the existing body of knowledge, and provides an insight to the practices of health and safety training in small and medium construction firms in Nigeria

    AN APPRAISAL OF TRAINING REQUIREMENT OF CRAFTSMEN IN THE NIGERIAN BUILDING INDUSTRY
    (2017-12) DAHIRU, D. ABDULAZEEZ, A.D. ABUBAKAR, M.
    Construction craftsmen are trained and skilled operatives who work manually with great proficiency in various stages of the construction work. Successful development and delivery of projects, largely depends on the participation of competent craftsmen. However, one of the problems affecting the construction industry in Nigeria is the quality and quantity of craftsmen; which is attributed to, among other things, high level of neglect accorded to their training. This study evaluates the training requirement of craftsmen in Nigeria. Field survey was undertaken using structured questionnaire as the instrument of the study. A total of sixty questionnaires were self-administered out of which 40 were returned and used for the research. Result showed that lack of support and encouragement from the construction industry with the mean 4.80 was ranked Is'as a major hindrance to training. Similarly, "vestibule Schools" and "sink- or- swim with mean of 4.20 and 1.55 were ranked highest and lowest, respectively, out of the 23 types of training identified, by the research, which can be applicable to the training of artisan and craftsmen. The study concludes that the training of Artisans and craftsmen in the Nigerian building industry is informal and learning activities take place outside official institutions. The study recommends increase in support from both Government and the construction industry in financing technical and vocational institutions. Similarly, Government should, from time to time identify major areas where the industry is lacking and come up with policy and programmes to remedy the problem. Regulatory body should also be put in place to monitor and recognize the activities of these construction craftsmen.

    AN ASSESSMENT OF THE IMPACT OF PROJECT RISK FACTORS ON PROJECT COMPLETION TIME IN NIGERIA
    (2021-02) ISIHAQ, Z. H. MUHAMMAD, S. ABUBAKAR, M. LAWAL Y.S.
    Completion time is an important criterion for determining construction project success. Many construction projects are completed behind schedule as a result of various risks involved in construction projects. Performance of project completion time can be improved if the risk factors that could cause delay are evaluated and managed. This study assessed the impact of project risk factors on completion lime of construction projects. Data was collected using structured questionnaires administered to 192 construction practitioners. 138 questionnaires were duly completed and returned but only 114 (59.38%) were found fit for analysis. Descriptive statistics was used to analyse the data. The study identijied financial difficulties of owner' (MS = 4.35), 'inadequate time estimate' (4.33), 'delay in progress payment by owner/client' (4.23), 'poor labour productivity' (4.22), 'shortage of skilled labour' (4.18) and frequent design changes' (4.05) to be the topmost risk/actors that impact on project completion time. The study concludes that financial', 'design' and 'contract administration and project management' related factors group are those with high impact on project completion time.

    AN EVALUATION OF SAFETY RISK FACTORS DURING INSTALLATION AND DISMANTLING OF TOWER CRANES IN CONSTRUCTION SITES
    (2020-07) SALIHU, A.A. ALIYU, S.S. ABUBAKAR, M.
    The construction industry plays a central and significant role in the economy of any nation. One of the major reasons for ineffective project delivery in the Nigerian construction industry is the improper assessment of risk factors. The industry however is currently facing a lot of challenges which include constant increase in the rate of accidents on construction sites which could be due to ineffective safety management as construction companies are usually interested in maximizing their profit in order to secure funds for new investments, and cover possible expenses associated with the occurrence of risk factors during construction. Installation and dismantling of tower crane had been previously looked at as a general safety issue until, recent research showed that about 69% of accidents related to tower cranes in Korea from 2001-2011, occur during installation and dismantling process. In view of this, this paper aimed at evaluating safety risk factors during installation and dismantling by determining their probability of occurrence and degree of impact with a view to establishing the most significant ones. This is why a well-structured questionnaire was designed to collect data with respect to their probability of occurrence and degree of impact using a 5 point Likert scale. Responses from the administered questionnaire and interactions were collated, interpreted and analysed using descriptive statistics (mean) and results presented in tables. Results showed that abrasion (wear and tear of components such as bolts, nuts, orpins) is the most probable factor with a mean value of 3.63. Fracture of a wire rope during dismantling had the highest degree of impact with a mean value of 4.63. The research concluded that fracture of a wire rope during dismantling and abrasion (wear and tear of components such as bolts, nuts, or pins) are highly affecting factor on safety during installation and dismantling. Adoption of a preventive maintenance strategy or routine check on the tower crane parts and components could help minimize the probability of occurrence and impact of the safety risk factors on site.

    AN EVALUATION OF THE EFFECTS OF NOISE ON STUDENTS IN THE MAIN LIBRARY OF UNIVERSITI TEKNOLOGI MALAYSIA
    (2013-11) DODO, M. ABUBAKAR, Muawiya
    The physical environment of a building should be within an optimal control level well enough to satisfy the needs of its occupants. Noise as a pollutant affects the productivity and morale of people. This paper investigates student's perception on the effects of noise in the Main Library of Universiti Teknologi Malaysia. Two hundred and sixty five students that come from over fifteen countries were surveyed. A structured questionnaire was used to collect data on student's perception to noise and its subsequent effect. Eta cross tabulation was used to establish relationships on the effects of noise and students perception. Results reveal positive relationships with small, medium and large categories of effects. Furthermore, while headache, feeling heavy headed and lack of concentration, were significantly related to student's perception, all other effects were not. As such, findings revealed that the more noise is perceived not manageable, the more its effect on headache, feeling heavy headed and lack of concentration towards the students. It was thus concluded that noise affects students in the library and can lower productivity in reading and learning of the students. The study recommends that sources of noise should be improved upon through adequate education and enforcement of library regulations.

    This study evaluated the environmental factors that lead to abandonment of building projects with a view to proffering solutions to the abandonment of building projects in Abuja. The study evaluated the environmental factors that were responsible for the abandonment of building projects. A structured questionnaire was designed and administered to the in-house consultants of the Federal Capital Development Authority (FCDA) because they act as consultants on behalf of the government. Data was analysed using descriptive statistics to determine the Means, Percentages and Relative Importance Index (RII) and results were presented using Charts, Tables, The study revealed that legal factors was the highest ranked factor (RllofO. 76) among the other environmental factors that lead to abandonment of public building projects. The research concluded that the legal factors contribute largely and immensely to the abandonment of public building projects. The research recommends that the government should give priority to the legal aspect of the construction environment before embarking on any public building projects.

    AN INVESTIGATION INTO THE LEVEL OF ADHERENCE TO THE BUILDERS DOCUMENT IN THE NIGERIAN CONSTRUCTION INDUSTRY
    (2013-08-26) DODO, Mansir KABIR, Ibrahim TSADU, Abdullahi Muhammad
    Since 2006, the Builders documents have been on transition in gaming limelight from its inclusion as contract documents in the National Building Code. Vie Code solely recognises the Builder as being responsible for the preparation of the Project Quality Management Plan, the Project Health and Safety Plan and the Construction Methodology. This study investigates the level of adherence to the usage of theBuilders documents amongst professionals in the Nigerian construction industry. Simple random sampling was used to fetch datafrom the 56 professionals studied through a structured questionnaire with only 40 of them returning after filling. It was found that even though 85 percentofthe respondents are aware of the existence of the Builders documents, majority do not fully use all 3 documents and three of the professionals studied still choose not to use the even though they are familiar with them. It was recommended that while more enlightenment should be done on the imperatives of the Builders documents in Building project delivery, better implementation mechanisms of the documents should also be enforced by statutory authorities so that construction delivery will be more efficient.

    Analysis of the Causality Links between the Growth of the Construction Industry and the Growth of the Nigerian Economy
    (2018-08-24) ABUBAKAR, Muawiya MUHAMMAD, Abdullahi BALA, Kabir
    The construction industry makes a significant contribution to the growth and development of every economy, by providing infrastructure for other productive ventures, shelter to the citizens and generating employment to people of different levels of knowledge and skills. In Nigeria, the construction industry contributes an average of over 3% to the annual gross domestic product and an average of about one-third of the total fixed capital investment. Despite the huge potentials of the Nigerian construction industry, little attention is given to its significance in driving the Nigerian economy to greater heights. This study explored the empirical evidence of causal relationship between the growth and development of the Nigerian economy and that of the construction sector. Econometric techniques such as unit root test, Granger causality test and Johansen's co-integration test were conducted to establish the actual relationship between the output of the construction sector (CS) and the gross domestic product (GDP) of the country. Twenty six years' time series data for the CS and the GDP between 1990 to 2015 was obtained from the statistics database of the Central Bank of Nigeria (CBN) and used for the analyses. The research revealed that despite the harsh economic realities facing the country in recent times, there exist a bi-directional linkage between the CS and the GDP of Nigeria. Each of them precedes the other by one year. The study recommends that any effort to diversify the Nigerian economy should consider revamping the construction industry for improved productivity in order to benefit from its significant positive effects on the economy.

    (2015) Ekwumemgbo, Patricia Adamma; Omoniyi, Kehinde Israel; Emmanuel, Amuntse Yerima
    Nutritional compositions of blood meal sourced from Bos primigenius (cattle) and Ovis aries (sheep) were determined. The moisture, ash, crude lipid, crude fibre, crude protein, carbohydrate (proximate), sodium, potassium, calcium, phosphorus (macro element), iron, magnesium, manganese and zinc (micro element) content of samples from Bos primigenius range from 8.99-10.08%, 9.01-10.99%, 7.15- 9.99%, 10.86-12.98%, 2.24-2.97%, 2.21-3.99%, 0.658- 0.885%, 0.122-0.322%, 0.648-0.883%, 0.119-0.196%, 1242- 1517 mg/kg, 2136-3925 mg/kg, 16.4-30.6 mg/kg and 17.01- 30.46 mg/kg respectively. Values for samples sourced from Ovis aries range from 0.98-80.01%, 72.31-77.01%, 0.05- 0.07%, 0.07-0.09%, 0.79-0.99%, 0.87-0.99%, 0.639-0.860%, 0.404-0.492%, 0.758-0.901%, 0.139-0.157%, 1425-1472mg/kg, 2468-3897 mg/kg, 46.40-55.10 mg/kg and 19.99- 50.97 mg/kg respectively. Comparison of the obtained values showed no significance difference. Therefore authors recommend the use of locally sourced blood meal as supplement to the expensive imported blood meal in order to reduce the cost of poultry production.

    ASSESSING THE LEVEL OF AWARENESS ON THE CONCEPT OF DESIGN FOR SAFETY (DFS) AMONGST DESIGN PROFESSIONALS IN THE CONSTRUCTION INDUSTRY IN NIGERIA
    (2021) ABUBAKAR, Muawiya ZAILANI, Bello Mahmud ADAMU, Abdulgaffar
    Designing for construction safety entails safety considerations of construction workers and end users in the design of a project with a view to improve safety performance in construction project delivery. Despite the apparent potential benefits of Design for Safety (DfS) in curbing the persistent safety hazards and accidents faced in the conduct of construction activities, little or no effort has been made in most developing countries including Nigeria to ensure its wide adoption and implementation. This has been argued to be largely due to the dogmatic: attitude of such developing industries towards conventional safety support systems and mechanisms. Thus, with a view to put the argument into clearer perspective, and also set the scene for effective DfS implementation in Nigeria, this study aimed to assess the level of awareness and readiness of professionals towards accepting the concept of DfS, and the possible changes that need to be made in the industry to facilitate its implementation. A quantitative research approach was adopted using a structured questionnaire to elicit data from randomly sampled professionals often involved in design for construction projects in the Nigerian construction industry. Data collected was analyzed using descriptive statistical methods. Findings of the study showed a relatively low level of awareness on the concept of DfS amongst industry professionals, and the need to constitute safety training programs which will go a long way in changing the perception of the design professionals towards safety. This will provide them with deeper insight on the contemporary trends in safety management tools and techniques for an improved safety performance.

    ASSESSING THE READINESS OF NIGERIAN PUBLIC SECTOR CLIENTS TO ADOPT BIM TECHNOLOGIES IN CONSTRUCTION PROJECT DELIVERY
    (2016-11) ABDULLAHI, M. ABUBAKAR, M. CHINDO, P.G. USMAN J.S.
    One of the major challenges facing the construction industry is the issue of fragmentation and lack of collaboration in the delivery of construction projects. To address this, several approaches have been employed with Building information Modelling (BIM) technologies as one of the recent approaches currently in use. Previous studies have reported successful implementation of BIM at different levels ranging from project, organisation, to industry level in many parts of the world especially the US and some part of the Nordic countries. However, to successfully implement BIM at any level, the drivers and barriers that influence effective adoption needs to be carefully examined and also all relevant industry stakeholders must be carried along in the implementation process. In Nigeria, studies have investigated the readiness of Building Design firms and contracting organisations to adopt BIM and have reported them to be appreciably ready. This study assesses the readiness of the public sector to adopt BIM technologies in its construction project delivery. A Questionnaire survey was administered to a sample of government Ministries, Departments and Agencies (MDAs) within Federal Capital Territory (FCT) Abuja. The questionnaire sought the perception of the respondents on the factors affecting BIM adoption in the Nigerian construction industry, and subsequently their level of readiness to adopt BIM technologies in their practices was assessed based on four core areas; management, people, process and technology. Arithmetic mean values were used to assess the drivers and barriers on BIM adoption. Results show that the public sector clients have achieved management, process and technology readiness but need to put in more efforts to improve people's readiness. Similarly, the agencies considered in the study have management and people's readiness but do not have process and technology readiness. The study concludes that the Nigerian public sector needs to improve its 'People readiness' to become fully prepared and ready to harness the potentials of Building Information Modelling in their services.

    (LIBRARY AND INFORMATION MANAGEMENT FORUM, 2017-07) DOGARA, Ibrahim; SHUGA, Yusuf; AHMAD, Aliyu
    This paper assesses how history scholars in Ahmadu Bello University, Zaria access and utilize Arabic and Ajami manuscript resources, using the theoretical paradigm of information perspective. The paper examined the objectives of teaching history in Ahmadu Bello University, Zaria. A brief history of the Department was captured, its structures and development. Arabic and Ajami manuscripts are described as handwritten documents containing information on history, education, literature, astronomy, medicine, culture, communication and natural sciences. These manuscripts are record in Arabic and in any other language using Arabic characters, such as Hausa, Fulfulde, Kanuri, Nupe, and Yoruba. The findings of the study show that scholars accessr -. and use the manuscripts with the aid of magnifying glasses and translation. The paper concludes with recommendations that the provision of more funds for that management and acquisition of the resources is worthwhile.
