Pengembangan Prototipe Aplikasi Kurir Antarjemput Kotak Amal LazisMu Umbulharjo Menggunakan Metode User Centered Design

LazisMu Umbulharjo has quite a number of social activities, including raising funds through charity boxes to several points, such as places of worship, community services, and Muhammadiyah residents in the Umbulharjo area and its surroundings. LazisMu Umbulharjo has managed at least 900 charity boxes spread across 7 sub-districts of the Umbulharjo area and also outside the Umbulharjo area. Currently, the courier who shuttles the charity box is guided by the address that is packaged in a printed sheet that comes from Excel data. Some of the difficulties experienced by couriers when picking up charity boxes at these 900 points, among others, the large number of points that must be visited by one courier. Couriers have difficulty memorizing the positions of the hundreds of charity boxes. Courier difficulties and often missed on the way to the points of the charity box. Problems occur if the staff replaces them with new ones so that adjustments are made from scratch again in learning the pick-up location. This research was conducted based on the stages in the User Centered Design (UCD) process. Plan the human centered process, specify the context of use, specify user and organizational requirements, product design solutions, and evaluate design against user requirements. Research has produced a prototype of the LazisMu Umbulharjo application with the main features of a dashboard for managing data and general information and managing a charity box. User management, charity box location management, and finally the determination of the pick-up route.

Based on this score, the prototype of the LazisMu Umbulharjo application can be accepted by users (ACCEPTABLE) with grade A and gets an EXCELLENT level

Design and Implementation of Mobility Management for Indoor Beam-Steered Infrared Light Communication System

This work describes a beam-steered infrared light communication (BS-ILC) system that facilitates non-shared and ultra-high data rate communications to individual user devices. The BS-ILC system comprises optical antennas, vision-based user localization, and optical receivers (each having a wide field-of-view photodetector and an IR-LED tag). Because of deploying narrow optical beams, the BS-ILC system requires efficient mobility management to support mobile user devices. This study develops a new BS-ILC model based on the Gaussian beam propagation that precisely estimates the user device's received signal strength from its localized position. Then, we propose mobility management consisting of two main components as location management and handover management. We further analyze the handover rate and the ping-pong effect to design the most efficient and robust handover mechanisms. Numerical and experimental results illustrate that the proposed mobility management can realize the seamless transmission, enabling >10 Gbit/s link per user.

Adoption of cloud-based enterprise resource planning payroll system state-owned enterprises in South Africa

Background: Cloud computing simplifies the access of applications and data from any location worldwide using Internet connected devices. Whilst adoption of cloud computing seems to be attractive, most companies are still using the on-premise enterprise resource planning (ERP) systems. Cloud computing provides organizations with scalable computer resources; nevertheless, state-owned corporations in South Africa have a poor adoption rate for integrating ERP and, in particular, payroll into the cloud (SOEs).Objectives: The goal of the study was to investigate factors affecting the adoption of ERP payroll cloud solutions in SOEs and basing on these factors develop an ERP payroll cloud solution adoption model.Method: In this study, a qualitative research approach was employed. Data were collected through observation, interviews and document reviews, and were analysed using thematic analysis method.Results: The a priori themes for this study: policy, security, cost, compliance and privacy were confirmed, whilst Protection of Personal Information Act, data centre location and top management emerged and were found to have a substantial influence in cloud ERP Payroll adoption process in SOEs.Conclusion: To move from on-premise to cloud ERP solution, SOEs managers need clarity on: Protection of Personal Information Act (POPI) act adherence, data centre location, top management support, privacy assurance, security guarantee, cost effectiveness, compliance controls and policy formulation adoption and implementation. The studied SOEs were not yet ready to migrate from on-premise solution to a cloud solution because of these factors. Addressing the above-mentioned concerns may enable SOEs’ managers to gain confidence in adopting cloud services.

A human capital‐based framework of career, well‐being, and social information reasons for managerial lateral job assignment preferences

AbstractResearch on job assignments has generally assumed employees will accept assignments when offered. In this study, we examine managerial preferences for potential job assignment opportunities conceptualized using human capital theory to provide a holistic understanding of this phenomenon. Using two pilot studies, we refine the list of reasons managers use when forming lateral assignment preferences. In the main study, we collected data from a representative sample of more than 1200 managers in a large US organization who provided preferences for all possible assignment locations (about 40) in their regions and reported reasons for their preferences. Results showed career development reasons (e.g., promotion potential, opportunity to learn) and social information reasons (e.g., location manager, customers) attracted managers to assignments, and health and well‐being reasons (e.g., commuting, stress) repelled managers. There were several differences in these relationships by managerial level such that health and well‐being reasons were more important than career development reasons for lower‐level managers than higher‐level managers, who seemed to generate their preferences based more evenly on both types of reasons. We ask whether gender moderates the relationship between health and well‐being reasons and preferences and find little support. We also explore whether manager racioethnicity moderates the relationship between community racioethnicity and preferences and find a few differences. Most findings were replicated when predicting actual movement 2 years later. Results suggest managerial preferences should consistently be considered in job assignment research and that organizations should obtain and use preference data when making internal staffing decisions.

A Location Management Strategy for Satellite Internet Constellation

Satellites are currently the most effective means to achieve seamless global coverage of the Internet. Due to the frequent beam switching caused by the high-speed movement of satellites, it is too expensive to directly apply the location management strategy in the terrestrial network to the satellite Internet constellation (SIC). To build a web browsing platform based on satellite Internet, it is necessary to display the location of satellites and terminals in real time. For this reason, this paper proposes the location management strategy of SIC. It uses the characteristics of large and periodic satellite beam coverage in a certain period of time, redesigns the location management database structure, location registration mechanism and call delivery mechanism, and analyses and simulates the bit cost of location management. The result proves that compared with the traditional strategy, this strategy greatly reduces the cost of SIC.

Strategy for Rice Disease Management in Bangladesh

Disease is one of the most limiting biotic factors that affects rice production worldwide. In Bangladesh, there are 10 rice diseases considered as major, which cause economic loss in farmers’ fields. Therefore, the aim of this article is to explore all the feasible avenues of technology deployment on rice disease management to restrict the disease infection at minimum level and thus minimize economic loss. The article is generated using data and/or infromation from published and unpublished works and incorporating authors’ experience. It is evident that periodically (odd year) a disease outbreak or epidemic occurred in Bangladesh such as blast. Under epidemic situation, research findings estimated a yield loss of up to 98% at the highest disease severity level of infection of blast. On the other hand, field survey indicated the highest of 65.4% yield loss from severly infected field with the disease. To overcome the epidemics in odd years and to keep the loss under economic threshold level, it is necessary to undertake preventive measures such as planting of resistant or tolerant varieties, use of disease-free seeds from healthy plants, use of balanced fertilizer where applicable, and following feasible crop rotations. Currently, it is urgent need for developing strong and precise weather-based disease-risk forecasting system at least one week’s lead time based on real-time weather data. Subsequent quick management options such as disease-specific fungicidal treatment should be communicated to all stakeholders using fast-delivery media such as TV channels and SMS could be efficient and effective ways to address the disease outbreak under epidemic situation. To address annualized yield loss, it is suggested to execute interventions like effective training to the root level (both for farmers and extension personnel) and conducting demonstration in farmers fields, regular field monitoring, digitalization in disease management sector, revive indigenous technologies as appropriate, and improving rice production system. To continously improve rice disease management sector, this paper has proposed an innovative action for three decades through to 2050 under the banner ‘Location, Variety and Disease Specific Smart Management’ on research, development and extension.

Project stakeholder’s engagement and performance: a comparison between complex and non-complex projects using SEM

PurposeThe large number of stakeholders in a project is a source of complexity because their inter-relationships can lead to complex interactions, an inadequate understanding of the other stakeholders and conflicting stakeholder interests. Although several studies have investigated the role and effects of engaging stakeholders in improving project success, studies examining the relationships between stakeholder engagement (SE) and quantitative and qualitative project performance (PP) in complex projects (CPs) have been limited. This study empirically examined the relationships between SE and project performance within complex and non-CP contexts.Design/methodology/approachThe study used an extensive literature review to develop the conceptual model. The study identified 22 factors of measuring SE and project performance’s association within the context of CPs. The literature review followed by a questionnaire survey to collect data from quantifying the relationships. One hundred forty-four responses were received from project managers in different locations. The response data were subjected to structural equation modelling analysis. Confirmatory factor analysis was applied to evaluate the measurements model.FindingsThe current study generated several key findings. In the context of CPs, SE was found to negatively affect quantitative PP but to positively and significantly affect qualitative PP. In non-CPs, SE also positively affects qualitative PP. Further, in the context of CPs, SE negatively affects schedule performance, whereas no significant relationship was found between the two variables in non-CPs. In terms of cost performance, no significant relationship was observed between SE and cost performance for either group.Originality/valueThis research provides insight into differences in the relationship(s) between SE and PP in non-complex and CPs. The research also makes recommendations for project team members.

Decision support framework for the regional facility location and development planning problem

Location choice is a crucial planning task with major influence on a company’s future orientation and competitiveness. It is quite complex, since multiple location factors are usually of decision-relevance, incomparable, and sometimes conflictual. Further, ongoing urbanization is associated with locational dynamics posing major challenges for the regional location management of companies and municipalities. For example, respecting urban space as location factor, a scarcity growing over time leads to different assessment and requirements on a company’s behalf. For both companies and municipalities, there is a need for location development which implies an active change of location factor characteristics. Accordingly, considering locational dynamics is vital, as they may be decisive in the location decision-making. Although certain dynamics are considered within conventional Facility Location Problem (FLP) approaches, a systematic consideration of active location development is missing so far. Consequently, they may propagate long-term unfavorable location decisions, as major potentials associated with company-driven and municipal development measures are neglected. Therefore, this paper introduces a comprehensive decision support framework for the Regional Facility Location and Development planning Problem (RFLDP). It provides an operationalization of development measures, and thus anticipates dynamic adaptations to the environment. An established multi-criteria approach is extended to this new application. A complementary guideline ensures its meaningful applicability by practitioners. Based on a real-life case study, the decision support framework’s strength for practical application is demonstrated. Here, major advantages over conventional FLP approaches are highlighted. It is shown that the proposed methodology results in alternative location decisions which are structurally superior.

Location of temporary buildings at LNG site based on quantitative studies

AbstractTemporary buildings, installed on site during the construction phase, may not be removed until the commissioning, completion, or beginning of normal operation. Once the hydrocarbons are introduced, these buildings have the potential to be exposed to process hazards (fire, explosion, toxicity, etc.) resulting in injury or fatality of the personnel inside the building. Providing safe location to these portable building is imperative and should be determined based on detailed hazard analysis, building siting study as per API 753. Facility siting study is done to calculate the potential impact of blast overpressure, thermal radiation from jet fires, pool fires, and toxicity hazards and evaluate the safe distance to the temporary buildings. Simultaneous operations is also evaluated in order to optimize temporary building location and further risk management strategies are implemented such as mitigation measures based on the hazard impacts, like, adding gas detectors at the air intake of HVAC to shut down the power supply to the temporary buildings, public announcement system, evacuation drills, and so on. This paper will address the temporary building siting study and associated mitigation measures with the highlight of its application into the risk management, using a large LNG facility as an example.

Surgical techniques in the management of supratentorial pediatric brain tumors: 10 years' experience at a tertiary care center in the Middle East.

Background: The goal of this retrospective study is to present the first epidemiological data on pediatric supratentorial central nervous system (CNS) tumors in Lebanon and to review the various surgical management strategies used.Methods: We conducted a retrospective case series of all pediatric patients who presented with a supratentorial CNS tumor and underwent surgery at our institution between 2006 and 2016. We collected and analyzed demographic characteristics, tumor location, clinical manifestations, histopathology, and surgical management strategies and outcome, and discussed them after dividing the tumors as per location and in view of published literature.Results: Ninety-nine children were studied with a male-to-female ratio of 2.3:1 and a mean age of 8.5 years. The most common location was convexity (44%) and included low-grade and high-grade glial tumors, along with other miscellaneous lesions. The next location was sellar/diencephalic (34%), including craniopharyngiomas, hypothalamic/optic pathway/thalamic gliomas, hamartomas, and pituitary/Rathke’s cyst, where there was notable use of endoscopic techniques (21%). Tumors in the pineal region (13%) were tectal gliomas, germ cell tumors, and pineoblastomas and were mostly treated endoscopically. The last group was lateral intraventricular tumors (8%) and was mostly choroid plexus lesions and ependymomas. Overall, the surgical objective was achieved in 95% with mild/moderate complications in 17%.Conclusion: A variety of pathologies may affect the pediatric population in the supratentorial region. Different surgical strategies, including microsurgical and endoscopic techniques, may be employed to remove, debulk, or biopsy these tumors depending on their location, suspected diagnosis, prognosis, and the need for treatment of possible associated hydrocephalus.

An electric-vehicle corridor model in a dense city with applications to charging location and traffic management

In this paper, we investigate an interesting commuting problem for an electric vehicle (EV) corridor in a dense city where en-route charging (including home- and workplace-charging) services are provided, and apply the proposed EV corridor model for charging location optimization and traffic management. Along a transport corridor in a dense city, EV commuters can choose either road paths (with/without en-route charging) or transit path to complete their home-to-workplace travel journeys. We first propose a user equilibrium model for the commuting problem in the EV corridor, by taking into account both departure time and travel path choices. Departure time equilibriums for bottleneck-constrained road paths with and without en-route charging are respectively derived. We also give a condition that ensures all EV users arrive early at the destination for the path with road and charging bottlenecks (serial bottlenecks), and discuss the existence and uniqueness of the user equilibrium solution. Based on the proposed EV corridor model, we further develop a joint optimization model of charging location and road capacity allocation, for two bottleneck-constrained road paths, to manage traffic flows. Numerical experiments are carried out to interpret the EV-corridor commute equilibrium and to validate the joint traffic management strategy in enhancing the travel efficiency of the EV corridor.

Examining the Impact of E-Commerce Growth on the Spatial Distribution of Fashion and Beauty Stores in Seoul

E-commerce has dramatically expanded its sales, with people being increasingly customed to online shopping. This study aimed to examine changes in the distribution of retail stores that provide fashion and beauty products and services in terms of the number of online shopping transactions and their spatial characteristics in Seoul. For this purpose, we analyzed location data concerning relevant newly opened and closed offline stores from four subgroups between 2015 and 2019. Though more offline stores were newly opened than closed in that period, the number of stores had overall significantly decreased apart from stores providing beauty services, with significant differences in subgroup spatial distribution patterns. We identified local geographic factors affecting retail stores by applying spatial regression models, and we found that the growth of e-commerce was associated with the related to the survival and closure of fashion and beauty stores. While retail store locations are not immediately responsive to changes due to COVID-19, we expect the prolonged COVID-19 outbreak will further facilitate the spatial transformation that has been stimulated by rise of online retailing. Our findings provide important basic data for establishing location plans and management strategies for future fashion and beauty stores, as well as timely evidence-based data to help direct subsequent academic research.

Targeted RNA sequencing reveals differential patterns of transcript expression in geographically discrete, insecticide resistant populations of Leptinotarsa decemlineata.

BACKGROUNDThe Colorado potato beetle (Leptinotarsa decemlineata Say) is a major agricultural pest of commercial potatoes, partially due to its ability to rapidly develop resistance to multiple insecticide modes of action. Patterns of L. decemlineata insecticide resistance in the contiguous United States have been linked to geographic location and regional management practices. Several previous studies have classified enzymes that are overexpressed following L. decemlineata exposure to commercial pesticides, many of which have been linked to xenobiotic metabolism. Studies have further associated geographic disparities in resistance patterns to cross‐resistance driven by fungicide exposure in the East Coast and Midwest.RESULTSIn this study, our objective was to investigate transcript expression of 38 previously classified detoxification enzymes induced by imidacloprid (an insecticide) and chlorothalonil (a fungicide) within five discrete populations of L. decemlineata obtained from areas in the USA representing eastern, midwestern and western production regions. We found unique patterns of transcript expression in different geographic locations, including overexpression of transcripts related to insecticide metabolism within insecticide‐resistant populations.CONCLUSIONThe results suggest the genetic response of these populations may be partially linked to geographic location and corresponding management practices. © 2021 The Authors.

Design of Cell-Based Flotation Circuits under Uncertainty: A Techno-Economic Stochastic Optimization

The design of cell-based flotation circuits is often completed in two distinct phases, namely circuit structure identification and equipment sizing selection. While recent literature studies have begun to address the implications of stochastic analysis, industrial practice in flotation circuit design still strongly favors the use of deterministic metallurgical modeling approaches. Due to the complexity of the available mathematical models, most flotation circuit design techniques are constructed based on deterministic models. Neglecting the impact of various sources of uncertainty may result in the identification of circuit solutions that are only optimal in a narrow region of specific operating scenarios. One promising strategy to address this shortcoming is through the Sample Average Approximation (SAA) methodology, a stochastic approach to handling uncertainty that has been widely applied in other disciplines such as supply chain and facility location management problems. In this study, a techno-economic optimization algorithm was formulated to select the optimal size and number of flotation cells for a fixed circuit structure while considering potential uncertainty in several input parameter including feed grade, kinetic coefficients, and metal price. Initially, a sensitivity analysis was conducted to screen the uncertain parameters. After simplifying the optimization problem, the SAA approach was implemented to determine the equipment configuration (i.e., cell size and number) that maximizes the plant’s net present value while considering the range of potential input values due to parameter uncertainty. The SAA methodology was found to be useful in analyzing uncertainty in flotation kinetics; however, the approach did not provide a useful means to assess the influence of uncertainties in ore grade and metal price, as these values are not significant in determining equipment size but rather influence the optimal circuit structure, which was not considered in this study. Results from an application example indicate that the SAA approach produces optimal solutions not initially identified in a deterministic optimization, and these SAA solutions tend to provide greater robustness to uncertainty and variation in the flotation kinetics.

Pattern of tree diversity in lowland tropical forest in Nikiwar, West Papua, Indonesia

Trees are significant components of ecosystems built by several widespread species. For instance, Papua forest is known to comprise abiotic and biotic elements. Also, certain plants have grown in popularity to a point where they are discovered almost everywhere. The purpose of this study, therefore, was to investigate tree diversity, distribution, and the importance of conservation. Data were collected in four locations using a total of 24 sample plots spread across Idoor, Karst, Persemaian, and Torembi, where seven, four, seven, and five plots were allocated, respectively. These forests formed a mixed natural plantation comprising 76 species from 35 families. Furthermore, Idoor and Karst generated the highest species diversity and varied significantly compared to Persemaian, while Torembi showed similarities with the other three locations. This condition formed three ecosystem communities across Persemaian, Karst, Idoor, and Torembi. Also, the composition of the dominant species showed variations at the seedling and sapling levels believed to structure the understory, while the pole and tree levels characterized the overstory. The total species status was described as critically endangered (CR) of two species, vulnerable (VU) of six species, least concern (LC) of 28 species, and data deficient (DD) species. Therefore, location management is advised to not only pay significant attention in terms of economic benefits but also ecological, including the provisions for ex-situ and in-situ conservation to support sustainable forest management.
