Published: December 2019

Abstract
The implementation of construction projects generally carried out in construction contracts results in community apathy because they are not actively involved in the planning, implementation and maintenance operations of construction projects. The government launched the National Community Empowerment Program (PNPM). One of the PNPM programs initiated was the Rural Infrastructure Development Program (PPIP). Election Implementation of a construction project using a construction contract or community empowerment by considering several criteria and sub criteria so that the implementation of construction projects can be carried out effectively and efficiently. The measures discussed in implementing construction projects are time, cost, quality, community participation, administration, and independence. The Analytical Hierarchy Process (AHP) method is used to analyze the results of the questionnaire so that the criteria and sub criteria weighted as a consideration for the selection of construction projects. Based on the results of the analysis, we obtained the weights of the construction project implementation criteria, namely: time with a load of 0.198, costs with a capacity of 0.203, quality with an amount of 0.178, community participation with an amount of 0.118, administration with a weight of 0.139 and independence with a weight of 0.139. Then it is known that the construction contract weight is 1.045 and the influence of community empowerment is 0.955.
Furthermore, the calculation of alternative weights carried out so that the criteria obtained: time, quality and administration took into account in the construction contract. Considerations: costs, community participation, and independence are taken into consideration by the project in community empowerment. Based on the results of the analysis shows that the implementation of construction projects is better done using a construction contract because it explicitly incorporated in its accountability. The cost criteria are the most significant factor and sub-criteria the accuracy of the start schedule of implementation occupies the highest score in the selection of the application of the construction contract.

Abstract
Problems of the embankment to be encountered above soft soil layer area are the stability of embankments such as: sliding/landslide, spreading, and sinking due settlement on soft soil layers excessive. The requirement of the safety factor of slope stability at embankment is relatively big, that is (SoF) ≥ 1.70 for approach bridge location and (SoF) ≥ 1.40 for approach bridge location. Safe Number on Model G1 Sheet pile Earthquake Mode is 1.356. So the minimum safe number for earthquake load (SoF) = 1.356 > 1.10 has been fulfilled. The program output produces a maximum moment value of 130.21 kN.m/m. The crack moment capacity of FCSP B 320.500 material is 66.5 kN.m/0.5m. When equivalent in the form of the moment of each meter length then the moment of resistance is 133 kN.m/m. Thus capacity resistance the moment of FCSP able to resist maximum moments, maximum moment value for 130.21 kN.m / m < moment of resistance is 133 kN.m m (safe). However, it is recommended to use minimal FCSP C 320.500 or greater for security reasons. The crack moment capacity of FCSP C 320.500 material is 72.4 kN.m/0.5m equal to 144.8 kN.m/m.

Smoothness, safety, and comfort of traffic depend on road pavement conditions. If the width of the road is narrow, damaged, hollow, the traffic will disrupted; the travel time will increase, fuel consumption increases, the risk of damage to high vehicles and so on, if there is no immediate improvement in the form of an increase, the damage will increase. To deal with this problem, it is necessary to research and plan road improvements with widening, an increase in existing pavements with overlays, the need for cost and time of implementation. The Mojokerto - Ploso road segment is an alternative route connecting the cities of Mojokerto - Jombang, and Lamongan. Based on the status of the road is the provincial road, and based on the function is the Collector’s road. Furthermore, for the planning of improvement and widening required subgrade CBR data, for overlay planning, a Test Pit data is needed to determine the existing pavement structure and traffic data. In determining the road widening plan, the 2015 revised Road Pavement Design Manual (MDP) method for overlaying was used with the Planning Guidelines for Pt-T-01-2002-B Bending Pavement Thickness and calculating the Budget using Work Unit Price Analysis (AHSP ) 2013, creating a Schedule of Work (Time Schedule), as well as calculating the critical path to find out the critical path in carrying out the work. To planning data analysis is needed - traffic data, land investigation, layer thickness calculation on widening, overlay layer thickness, cost requirements, execution time and critical track path. From the calculation results, the road widening obtained AC = 5 cm pavement arrangement, ATB = 14 cm, CTB = 30 cm, Class B Aggregate = 20 cm, the optional load support layer = 85 cm, using geogrid as the selected urine separator with subgrade, in the old pavement repair (overlay) with an overlay, the AC = 5 cm arrangement, ATB = 14 cm, at a cost of Rp. 19,200,000,000.00 (Nineteen billion two hundred million rupiahs) with a 20-year plan life, as well as a 6-month implementation time.

Published: December 2019

Abstract
This work presents the development of a cost effective vertical axis wind turbine for generation of compressed air using locally sourced materials. The design of the wind turbine takes into consideration the reduction in the weight and size of the turbine thereby lowering production and installation costs. This increases the efficiency by increasing the resistance from dynamic loads and reduction of acoustic noise discharge. The following locally sourced materials were employed for the development of the wind turbine compressed air system: acrylonitrile butadiene styrene, teflon, polyethylene terephthalate, mild steel, rubber and wood filings. The blade design is of the form airfoil shape of NACA 2412 type typical of air crafts wings with a chord of 50 mm and utmost camber of 2% sited 40% (0.4 chords) from the leading edge and utmost thickness of 12% of the chord. The aerodynamic properties include angle of attack which is 2.2° and the utmost twist angle which is 25.66°. From the performance evaluation, maximum tip speed ratio of 0.9 was achieved as well as power output generation of approximately 14 watt at 10.2 m/s wind speed. The findings of this project identify compressed air energy storage as a viable alternative to chemical energy storage generated from wind turbines. The developed turbine will contribute significantly to the effective conversion of wind kinetic energy into pressure energy as opposed to electrical.

Published: December 2019

Abstract
Basement workplaces are considered as confined environment with challenging indoor air quality having higher than normal pollutants particularly that of soil gas origin. Radon a major soil gas infiltrates and accumulates within indoor spaces and becomes harmful in the absence of natural or mechanical ventilation. Radon level in bank basements in Ilorin, Lagos and Akure have been sampled and analysed in this study. The paper presents the investigations conducted to measure the radon concentration in the occupied basement component of the bank buildings. Most workers in basements are unaware of radon, and there is limited documented research on its health hazards in Nigeria. The survey parameters were radon concentrations, floor levels, geographical locations and the influence of atmospheric conditions. Corentium monitor, a continuous, digital radon monitor, in addition to, temperature meters and Prologue wireless weather station were used for the experiment. The result showed an indoor radon concentration and effective doses annual mean values of 23 Bq/m3 and 0.0896mSy/y respectively in the occupied basements.

AbstractFiberboards are engineered woods made from a composition of wood chippings, wood fibers, sawdust etc., glued together with adhesives. Low density fiberboards (LDF) are part of the classes of fiberboards widely used in Nigeria because they are readily available, relatively cheap and offer good aesthetic values, compared to conventional woods. However, they possess low strength, durability and lifespan, thus making them susceptible to damage during service. The aim of this study was to determine the effect of kenaf core and bast fibers (Hibiscus cannabinus)as one of the dispersing phases in low density fiberboard production, also known as particleboards. The materials and methods employed in the study, followed procedures in established standards and literatures. The different composite materials were weighed and mixed properly for about 10 minutes to ensure homogeneity in the mixture. Thereafter, the materials were placed in a mould of uniform thickness and compressed to different fiber board samples using a compression press machine, for about 10mins. A series of physio-mechanical tests such as water absorption, density, tensile strength, modulus of elasticity and modulus of rupture were conducted on the developed fiberboard samples as well as the control samples. The results showed that the average values for water absorption and density of the developed samples enhanced with kenaf core and bast fibers were 5.480% and 0.027 g/cm3respectively. These values compare well with that of the control samples. Also, the tensile strength, modulus of elasticity and modulus of rupture of samples enhanced with kenaf gave average values of 31.842 MPa, 2.920 GPa and 16.58 N/mm2respectively. These values also compare well with that of the control samples. From the results gotten and all the properties determined, the study showed that kenaf core and bast fibers can be employed appreciably as dispersing phases for low density fiber board (LDF) composite production.

Published: December 2019

Abstract
Substrate – coating behaviour plays a crucial role in determining the efficacy of the resulting properties of thin film coating. This research work studies the impact of two different substrates (Ti6Al4V and CpTi) on the mechanical properties of Titanium carbide thin film coating deposited using RF Magnetron Sputtering. The tribology properties were characterized using Nanoscratch and Tribo-tester. GIXRD and FESEM were used to study the structural and surface morphology of the coatings. The micrograph images of the FESEM show a similar trend for the film distribution while the GIXRD highest peak intensities vary for the coating. Spallation, bending crack and delamination of the film were noticed under high load condition and the micro-scratch result shows good adhesion between the coating and the substrates.

Published: December 2019

Abstract
Drilling operations in deep-water environment is faced with technical challenges despite its massive record of huge hydrocarbon reserves when compared with onshore oil and gas fields. The weak, unstable formations coupled with adverse deep-water conditions poses as a challenge to cementing operations. Narrow pressure window conditions are encountered when the wellbore pressure required to contain subsurface pressures lies close to the pressure at which losses may be sustained. This is evidence in the ratio of pore pressure to vertical stress moving close to lithostatic condition. This can either be caused by porous formation or by the way of inducted fractures in weak or sheared or unconsolidated zones in the subsurface. This study showed an overview of some possible challenges faced in deep-water cementing operations in relation with stratigraphic features of the deep-water environment. From the review it was gathered that the stratigraphic nature of deep-water environment has a huge effect on cementing operations for oil and gas wells. The study also highlighted some gaps in the literature which require urgent attention to reduce loss circulation. These gaps include but not limited to: spacers generating sufficient downhole force to overcome the yield stress of the mud and the need for a new type of treatment for lost returns. Managed pressure cementing operations may control wellbore pressures.

Abstract
Recycled water at a facility in Yola, Nigeria was studied for its suitability for irrigation. Biological and physicochemical analyses of the recycled water samples from four different points namely; A (inside pool; chlorinated), B (outlet 1; after chlorination), C (outlet 2; before receiving tank) and D (outlet 3; for irrigation) were carried out for four weeks. The physicochemical analysis include temperature, pH, turbidity, NO3-, total dissolved solids (TDS), Cl-, heavy metals and alkalinity were studied. The pH values obtained varied between 6.9 and 8.1 and were within the acceptable values for irrigation water. The water samples obtained in week 4 had higher turbidity and TDS values as against samples obtained in weeks 1, 2, and 3. High NO3- concentration was found in the water sample taken in weeks 1 and 2 compared to weeks 3 and 4 water samples. Meanwhile, Cl- concentrations were low in the water samples obtained in weeks 1 and 2 relative to concentrations in weeks 3 and 4 water samples. Metals detected from AAS were copper with 4 x 10-5 ppm in all the points (A, B, C and D). The concentrations of iron were 2.72 x 10-3, 5.54 x 10-3, 3.62 x 10-3 and 2.98 x 10-3 ppm in samples A, B, C and D, respectively. Fecal coliforms present were pathogenic coliforms and the Biochemical Oxygen Demand (BOD) analysis showed negative values due to presence of chlorine in the water samples. There are benefits of availability of recycled water for irrigation but care must be taken not to infect users with pathogenic coliforms which are hazardous to health.
