Three main phases were involved in this project, which are defining requirements, analyze requirements and validate requirements. The requirements are defined in a way that they are suitable to be used by
small to medium sized companies. The requirements are analyzed by constructing use case diagram, use case specifications, class diagram, activity diagrams and the list of requirements. A working prototype is developed using open source software to validate the requirements. The prototype can be readily used by small to medium sized companies, and can be a base for them to develop their own help desk system that includes other requirements and enhancements which are deemed fit for their needs
The indirect impacts of management support and commitment on knowledge management systems (KMS) adoption: evidence from Malaysian Technology Industries
The study investigates the impacts of management support and commitment on the adoption of knowledge management systems (KMS) in Malaysian technology industries. By analysing data from a survey of 108 managers across the Malaysian technology industries, the study contributes to the KMS adoption literature by empirically establishing the indirect impacts of organisationsā management support and commitment through the mediations of other organisational elements. First of all, the results suggest that the effects of management support and commitment are only indirect through the mediation of other variables, namely knowledge classification and knowledge sharing culture. Moreover, knowledge classification has a positive influence on perceived benefits, which is a determinant of KMS adoption. Second, even though management support and commitment has a positive impact on rewards and incentives, and policy and procedures, the findings indicate that these organisational elements did not have any influence on KMS adoption. However, policies and procedures did influence perceived ease of use, which is a determinant of perceived benefits. The theoretical and practical implications of these findings are discussed
Information technology for knowledge management in Malaysia: The effects of organisational factors
This study attempts to identify organisational
factors that could influence the adoption of IT to support KM in a Malaysian setting. In addition to the two major constructs of the technology acceptance model (TAM), a research model was developed by incorporating six variables of organisational factors. Analysis of data collected from a survey of 830 Malaysian listed organisations showed that all variables of organisational factors have significant contribution to the adoption of IT for KM, except management support and commitment, and reward and incentive.
This research outlines some management
implications and extends the applicability of TAM in Malaysian KM context
Uji Aktivitas Antioksidan Pada Teh Chamomile Kemasan Berdasarkan Variasi Suhu Dan Lama Penyeduhan Dengan Metode Dpph (1,1-diphenyl-2-picrylhydrazyl)
Antioxidants can neutralize free radicals and protect the body from various diseases by binding to free radicals and highly reactive molecules that can damage cells. Increased knowledge about free radical activity has resulted in the use of antioxidant compounds being increasingly developed for food, beverages, and treatment. Tea is a very popular drink and is consumed by almost all people in the world and become an important agricultural product, one of them is Chamomile tea. Chamomile tea comes from Chamomile flowers which contain lots of chemical compounds such as tannins and flavonoids namely: polyphenol compounds and their derivatives. Group of compounds Tea is one type of functional beverage because in tea is contained natural antioxidants, namely flavonoids that can keep the body from free radical attacks. This study aims to determine the influence of temperature and duration of brewing antioxidant power in the water of broom tea by using the DPPH method.

Development of an Airflow Monitoring System for Air Handling Unit using IoT
This paper presents the development of an airflow monitoring system for air handling units using NodeMCU ESP32. The main purpose of this project is to improvise the use of microcontroller with on-par performance for industrial applications. This proposed system consists of two sensors that measure airflow from the air handling unit. The first sensor is an airflow speed, which measures the airflow speed from the air handling unit. The second sensor detects and indicates the temperature and humidity of the airflow. The testing parameters show very good correlations among variables, indicating the efficiency of the system to monitor the airflow.

Organisational factors enhancing the use of information technology for knowledge management: a study in Malaysian listed organisations
Managing knowledge appears to be key in improving organisationsā competencies in the face of global competition. In the case of Malaysian organisations, extant studies revealed a disparity between perceived importance of information technology (IT) and its actual utilisation to support knowledge management (KM). In order to achieve a knowledge-based economy, Malaysian organisations need to embrace the use of IT to support their KM initiatives to ensure that knowledge is diffused and applied in the best possible way to support further innovation and drive economic growth. Hence, the acceptance and use of IT in Malaysian KM is of paramount concern.This research addressed this issue by examining IT utilisation by Malaysian organisations to support KM. Research has shown that failures in deploying ITbased systems to support KM are in part attributed to the inadequate attention to other factors, such as structures, processes, and culture of an organisation. Thus, the main objective of this study was to understand the key organisational factors enhancing the use of IT to support KM in the Malaysian listed organisations. Furthermore, most of the studies on IT use for KM were conducted in the Western context. The current research was conducted in the Malaysian context, using a model that accounted for key variables, the relevancy and appropriateness of such in the particular context being verified in the preliminary investigation phase of the research.The technology acceptance model (TAM) provides the theoretical framework for this studyās investigation. In addition to the two major constructs of perceived usefulness and perceived ease of use in TAM, six variables of organisational factors, garnered from a review of relevant literature and validated by a series of interviews in Malaysian listed organisationsāincluding management support and commitment, knowledge sharing culture, rewards and incentives, knowledge classification, and policies and procedures of using IT for KMāwere incorporated in the research model proposed for this study. Based on the findings from the preliminary investigation phase, another organisational factor was identified, namely, having appropriate KM processes to manage knowledge in an organisation, and thus was added to the refined research model. A survey was conducted among 830 IT and KM managers from the Malaysian listed organisations to collect quantitative data. The data collected were analysed using the structural equation modelling (SEM) approach with partial least squares (PLS) technique to test the hypotheses developed and assess the research model.The major findings of this research have confirmed the influence of KM processes, knowledge classification, knowledge sharing culture, and perceived benefits of using IT for KM as the major determinants of IT use to support KM in the organisations studied. However, the positive effects of rewards and incentives, policies and procedures of using IT for KM, and perceived ease of use, on the extent of IT use for KM were not detected. Furthermore, the results demonstrated the effect of management support and commitment on the use of IT for KM was only indirect through its mediation on knowledge classification and knowledge sharing culture. The results also suggested that the research model explained almost two-thirds (65.6%) of the variance in IT use for KM.This research provides significant and original contributions to the existing knowledge in the acceptance and use of IT to support KM area. The unique theoretical contributions of this study include the demonstration of an extension of the TAM to investigate the influence of organisational factors on the extent of IT use to support KM, in particular, in the context of Malaysian organisations. The results of the study have important practical and theoretical implications for employers, governments, information system professionals and information system researchers. Most importantly, an understanding of the organisational factors enhancing the extent of IT use for KM provides guidelines for the Malaysian organisations in developing better KM and IT strategies in order to promote and encourage the use of IT to support the organisationsā KM initiatives
Organisational factors for information technology implementation in knowledge management:a Malaysian perspective
Managing knowledge appears to be a key in improving competencies for Asian Pacific organisations in the face of global competition. In this region, IT has been identified to play a critical role in an organisationās capability to manage knowledge. In the case of Malaysian organisations, extant studies revealed a gap between perceived importance of information technology (IT) and its actual utilisation to support knowledge management (KM) in Malaysian organisations. In view of this problem, this paper attempts to identify the organisational factors for successful IT implementation to support KM in a Malaysian setting. Review of literature indicates six dimensions of organisational factors for successful IT implementation in KM, which are organisational culture, reward and incentive, knowledge classification, institutionalisation of IT, perceived advantages of using IT, and managementās perception on the use of IT for KM.Findings from interviews in three Malaysian organisations generally support the relevancy of all proposed dimensions. An āIT for KMā model was developed along with a survey instrument to measure constructs, test hypotheses, and validate the model. A pilot study of the instrument was conducted to determine its validity, reliability, and for further refinement of the instrument. Results from a sample of 150 Malaysian publicly listed organisations in the pilot study indicate that all organisational factors proposed are significantly correlated to the level of IT use for KM in Malaysian organisations, with the exception of one factor, which is managementās perception on the use of IT for KM. This paper provides an insight for effective IT implementations for KM in Malaysian organisations, validates the existing theoretical framework for IT use for KM in a Malaysian context, and contributes towards managing complexities in the Asian Pacific region
IOT gas leakage detection, alert, and gas concentration reduction system
LPG is a common industrial and household item, which is extremely flammable. Many accidents have occurred because of LPG leaking, whose causes range from improper installation to the usage of faulty gas cylinders. Serious accidents that cause bodily harms or even fatalities can be avoided if the leakage is detected early before it initiates huge fires and causes damage to the surrounding where the LPG container is installed. This study proposes and develops an improved design of a system which detects LPG leakage, such as methane, butane, or any other petroleum-based gaseous liquid. Combining the gas leakage detection system with an IoT system shall provide mechanism to instantly contain the severity of LPG leakage and send instant alerts. In this system, an MQ-6 sensor and NodeMCU with ESP8266 WIFI module are used to detect gas presence, in which a relay will turn on to activate an exhaust fan to instantly reduce gas concentration whilst sending alert notification to user via an app. The information will then be transmitted over the internet to a database, in which the information will be accessible via an app configured specifically for the accessibility by the user
