Study to Investigate Variation of California Bearing Ratios of Soil Materials with Changes of Soaking Duration
Get PDFThe study was conducted to investigate variation of CBR values with soaking duration. Four sample materials were used for laboratory tests which are cinder and natural pozzolan from Ituha borrow pit, clay soil from Mlimanyoka borrow pit in Mbeya region and then the three source materials were blended together to obtain a fourth sample materials. Characterizations of soil materials were conducted including maximum dry densities (MDD) and optimum moisture contents (OMC) were determined. The results for MDD and OMC for the four soil samples are 1680kg/m3 and 13.2% for cinder, 1543kg/m3 and 19.5% for natural pozzolan, 1524kg/m3 and 23.4% for clay and 1642kg/m3 and 15.6% for blended sample respectively. The variation of California bearing ratios (CBR) for four soil samples were determined. The CBR values of sample materials were determined for unsoaked samples, 4 days, 8 days and 12 days soaking duration. The results of CBR values at 95%MDD for the four samples soaked for four days are 16.5% for cinder, 23% for natural pozzolan, 4.8% for clay soils and 27.4% for the blended sample. The results indicated that there are exponential decrease of CBR values with increasing soaking duration to the residual values after fully saturation of soil sample. The high CBR values of blended sample enhanced by interlocking and friction properties of the mixtures and addition of clay which act as binder to none plastic soils. It is important to determine CBR values at longer soaking duration than 4 days whenever the soil materials are to be used in areas with high water tables and frequent rainfalls. For easy estimation of CBR values for a particular soaking time, an equation has been developed, which will reduce time for laboratory works to determine CBR values at longer soaking duration
Effect of Thickness and Temperature Variations on Some Structural, Optical and Electrical Properties of Electron Beam Deposited CdS Thin Films
Get PDFThin films of cadmium sulfide (CdS) by electron beam deposition on glass substrate. The structure of the films was investigated by X-ray diffraction (XRD). The CdS films were found to be crystalline and hexagonal with the c-axis perpendicular to the substrate. Annealing in air at 4000C greatly improved the crystallinity of the films as well as increasing their grain size. The optical properties of the films have been studied by transmission/reflection spectroscopy. The CdS films had optical bandgaps in the range 2.35-2.42 eV, which were dependent on the film thickness as well as on temperature. A reduction in the bandgap was also noticed for the annealed films. In addition, the single-effective oscillator parameters have been evaluated and their dependence upon film thickness discussed.
From d.c. electrical conductivity measurements it was found that the conductivity of the CdS films is a function of the thickness of the film, increasing with the thicker films. The electrical conductivity is greatly improved when the film is air-annealed. From values of the activation energy of conduction it was concluded that conduction is dominated by states close to the conduction band

Application of Automatic Yarn Winder to Improve Productivity in Balinese Traditional Weaving Businesses
Get PDFWeaving is a fabric craft made by combining threads crosswise and lengthwise. Before carrying out the weaving process, the winding thread process is usually carried out. However, one of the weaving artisans from Jembrana Regency still does the thread-winding process manually. Winding yarn with a manual tool takes quite a long time. The results of the yarn spools are not neat and cause physical complaints. Therefore, an automatic yarn winder innovation was created. Automated yarn winders can help weavers by providing convenience in the yarn winding process through the technology offered, namely the use of DC motors, Arduino nano, BTS7960 motor drivers, keypads, and LCDs. By providing these solutions and conveniences, cagcag weaving artisans can carry out the winding thread process more quickly, the results of thread rolls are tidier, and they can eliminate physical complaints they experience. Through the application of this tool, the productivity of traditional cagcag weaving artisans has increased
Comparison of Student Achievement in Teaching Analytic Geometry of Planes and Space Using GeoGebra and PowerPoint Media at STKIP Abdi Wacana in Semester VI of the Academic Year 2021/2022 in Wamena
Get PDFThe research examines the comparison of student learning achievement on the topic of analytic geometry of planes and spaces, which is taught using two different learning media, namely GeoGebra and PowerPoint media. This experimental research used two different experimental classes, each consisting of 14 and 15 students. The research design used is a counterbalance design because even though students\u27 initial knowledge is homogeneous, there are still many other variables that affect the process and learning outcomes, which cannot be controlled and are not homogeneous. The research data used were pre-test and post-test scores for each treatment, which were then processed to obtain normalized gain data. Data processing was carried out using SPSS software and was preceded by an analysis of homogeneity tests and normality tests.
Based on the Wilcoxon Signed Test, it is clear that the two learning media are able to improve student learning outcomes. The paired samples test is used to compare the learning outcomes of the two learning models. The results showed that learning using GeoGebra media gave higher learning outcomes compared to using PowerPoint media. The average normalized gain difference between the two media is 0.34
Identifying the Gap in User Satisfaction Assessment from Different Perspectives in Public Institutional Buildings
Get PDFThe building is a place that is responsible for meeting its users\u27 needs and expectations, and offering them a safe and comfortable environment. Many researchers focus on evaluating the user satisfaction level in different Building Performance Levels (BPLs). However, measuring the end-user satisfaction is not an indicator of the importance of the BPLs and its attributes to the end-users. This paper aims to identify the gap between the importance of different performance levels from the user\u27s and the architect\u27s perspective, and the frequency of their application in scientific research. Two surveys were conducted to 172 architects and end-users. Then, a structured review highlights the frequency of applying user satisfaction assessment in each BPLs. The results showed that the gap between the architect and the end-users in identifying the importance of each performance level in building is low not exceeding 12% in any performance level, but there is a clear gap in research related to measuring user satisfaction in the functional, technical, and aesthetic performances by (38%), (39%), (12%) respectively, compared to their importance in affecting the level of user satisfaction in buildings
