Abstract : Agricultural adoption has been progressed for cost reduction intended in diverse fields. There are various occasions to apply for creating web applications as a tool in data collection for business analytics and automatically establishing conveyor belts for feeding and planting in parts of agricultural extension, technology and cooperatives that concentrate on numerous essential issues. This paper, we endorse agricultural management by collecting vital information in a data collection tool using web application to deal with business analytics. The method takes the Internet of Things concept by integrating the systems from enormous raw data in necessary food matters such as vegetables, fruits, chickens, and fish. The vital distributions would appraise the growth duration. Outstandingly, the application achieved its purposes to notice those important occurrences in strategic cost-effectiveness; demonstrate total revenue, expenditure, net profit, and determine worker behavior and food utilization as a key performance indicator..

Abstract : Performance of zinc oxide (ZnO) nanorods directly grown on fluorine-doped tin oxide (FTO) electrode at different precursor concentration and hydrothermal reaction time as an electron transport layers (ETL) in chloride modified perovskite solar cell (PSC) has been examined. The obtained ZnO nanorods were characterized using a field emission electron microscope (FESEM) to reveal nanorods morphology whereas X-ray diffraction (XRD) was used to examine the crystal structure and the phase formed. Performance of ZnO nanorods as an ETL in a PSC device was examined by analyzing current and voltage (I-V) curves obtained through a semiconductor parameter analyzer. The results showed that with the increase of reaction time and precursor concentrations during the hydrothermal process increased diameter, crystallinity, and peak intensity of the obtained ZnO nanorods. The optimum power conversion efficiency of 2.740% was obtained from the sample with precursor concentration of 0.0375 M and hydrothermally synthesized for 3 hours..

Abstract : Traffic volumes are widely believed to be key issues in the change in road surface conditions. The present study analyzed the impacts of traffic volumes of different vehicle categories on the change in road roughness as indicated by International Roughness Index (IRI) in Indonesia inter-city roads. The road volume-to-capacity ratio (VCR) was also considered in the modelling. The study used the data of 13 roads spanning 139.63 km on the north coast of Java. The analysis was made on three categories of vehicles: heavy vehicles, light vehicles and motorcycles, which were regrouped from the initially seven categories surveyed. A fixed-effects regression model for panel data was applied with repeated measurement over six years. The fixed effects method assumes that the intercept is different between subjects and the slope is the same between subjects. Using linear and non-linear regressions (Generalized Additive Model), the results show that heavy vehicles' AADT (Annual Average Daily Traffic) determines the change in IRI values. The findings will contribute to the management of road sustainability..

Abstract : Museums have been forced by the pressure of change to switch practices and outlooks to transform museum visitors from passive consumers in a collection-focused ‘static exhibition’ to active participants in a visitor-centred ‘interactive technology exhibition’. This paper aims to model a framework for museum exhibition design that can be used as a prototype evaluation tool. It is achieved throughout analysing the interrelationships between museum visitors learning identities and their museum experiences and what are the display techniques that can be used to increase museum visitors’ social interaction with the museum environment and how each technique will affect the visitor’s learning behaviour and the nature of museum visitor experience in a digitally responsive interactive exhibition. Three quantitative methods tested and evaluated the museum visitors learning identities and their experiences on Giza Zoo zoological museum and modelling the prototype evaluation tool that can be used as a tool for future museum exhibition design, redesign, and evaluation..

Abstract : Applying cutting fluid is a common case in machining, as it can prolong the tool life. However, excessive using it may cause a bad affect on the operator and environment. Alternatively, applying minimum quantity lubrication (MQL) to reduce the bad effects yet gain a maximum advance of using cutting fluid. This study aims to determine the most optimal parameters in the AISI 4340 steel turning process with a minimum quantity lubrication method to produce the best chips formation. The best chips were measured by their possibility to break by the term degree of serration (DOS). The experiment design used was the Taguchi orthogonal array L9 〖(3〗^4). method. The varied parameters were the depth of cut, cutting speed, method of giving cutting fluid, and feed rate. Based on the mean response value, it can be concluded that to get the most optimal results of discontinuous chips would be achieved by combining parameters: depth of cut 2.2 mm, cutting speed 200 m/min, flood type cutting fluid application, and feed rate 0.107 mm/rev. Each parameter contributed to the degree of serration in order are the method to apply cutting fluid, depth of cut, cutting speed, and feed rate by 82.87%, 7.38%, 5.41% 4.14% respectively..
