However, only a few have examined biodiesel from the logistics perspective, while most of the scientific investigations have addressed the production issues, e.g. efficiency, diversification and processing technology (1 st , 2 nd or 3 rd generation). In spite of this, biodiesel poses a problem for logistic processes, such as facility planning, transport, and routing-scheduling associated with quality control along with continuity of feedstock supply. In some developing countries, the management of the biodiesel industry has also become a predicament. Even though developed countries have commonly established a national agency in charge of the biodiesel business, the institution is still in the early stages of standardisation and quality control. Currently, there is no agency concerned with supply chain governance that is capable of integrating the biodiesel business from upstream to downstream. In this thesis, the author presents a procedural technique to assess the biodiesel industry. This procedure combines business modelling/analysis (using General Electric/Mc. Kinsey Matrix), simulation, conceptual design and a prototyping system. The study provides scientific insight for planning a digital biodiesel supply chain and proposes a framework for governing such a system from upstream to downstream. The researcher employs a holistic approach, where biodiesel is not seen as a separate entity because it comes to the consumers through a long chain dependent on various aspects. Currently, a number of companies have implemented Enterprise-Resource-Planning to manage their businesses, but unfortunately, they have not been able to reach the entire value chain. Digitalisation is desirable when integrating the Information Systems of all supply chain members. A control tower must be built to accommodate such an idea and monitor the entire process. Then, the best standardised quality and sustainability can be achieved. The author also offers a transition concept in the implementation level, because, in reality, the members in the supply chain have no similar Informastion-System standard. The results from literature studies, simulations, prototyping, theoretical arguments, and conceptual design present a digitalisation pattern in the biodiesel supply chain for sustainable development.

Most Internet connections nowadays are accessed using mobile devices in order to stay connected all the time and everywhere. Owing to the limited coverage of such access points as well as base stations, mobile devices are required to handover connectivity if there is a move to other locations. Horizontal handover is conducted when the movement is within the same network. Otherwise, there must be vertical handover when external network infrastructure is encountered. However, as the Internet is an open network that naturally lacks trust between users, the mobile nodes that move to an external network are susceptible to various attacking activities. Compromising mobile nodes may cause users to lose their data as well as destroy their mobile devices in terms of both software and hardware. Securing mobile devices is crucial in order to avoid losses in terms of not only m...

Due to the dynamic nature of human activities, the evolving mobile technology has played a significant role and it is reflected in the exponential growth of the number of mobile users globally. However, the characteristic of the Internet as an open network made it vulnerable to various malicious activities. To secure communication at network layer, IETF recommended IPsec as a security feature. Mobile IPv6 as the successor of the current mobile technology, Mobile IPv4, also mandated the use of IPsec. However, since IPsec is a set of security algorithm, it has several well-known weaknesses such as bootstrapping issue when generating a security association as well as complex key exchange mechanism. It is a well-known fact that IPsec has a high overhead especially when implemented on Mobile IPv6 and used on limited energy devices such as mobile devices. This paper aims to enhance the IPsec performance by substituting the existing key exchange algorithm with a lightweight elliptic curve algorithm. The experiments managed to reduce the delay of IPsec in Mobile IPv6 by 67% less than the standard implementation.

It is slowly gaining its importance in our daily life. Nevertheless, there are several problems emerged in the biodiesel supply chain, e.g. biodegradability, quality control, disturbance in the distribution of biodiesel, interrupted feedstock, supply and lack of governance. A new approach of biodiesel supply chain management has been developed based on mobile-application to overcome such problems. Determining the fact that biodiesel is degradable over time, the system also possessed by feature to maintain the biodiesel quality during transport, besides bringing-out simple and user-friendly supply-trading application on hand to hand. A wide range of biodiesel supply chain monitoring, distribution tracking and quality checking are demonstrated during the process of ordering, stocking, buying and sending biodiesel. The mobile-application has been tested for performance analysis on processor, battery and data usage. All menus, performance test and survey show good responses although at the security aspect is found the necessity of extra-development. Further analysis indicates that such system also fit for feedstock plantation, cultivation, harvesting and procurement. Overall, this method is worthy suggested to be implemented on the accreditation board of biodiesel that manages the entire supply, orders, trades and quality of biodiesel from upstream to the downstream.

Dengan adanya system informasi yang kompleks, dibutuhkan system penyimpanan database untuk menunjang berjalannya system informasi tersebut. Dalam prakteknya, system informasi itu ketika diakses oleh client kadang terjadi kegagalan. Salah satu solusi untuk mengatasi permasalahan di atas, dengan menggunakan teknologi database cluster. Dengan menggunakan metode clustering master-master performa sebuah database akan meningkat karena penanganan arus data dari client tidak ditangani oleh 1 server saja. Hal ini dapat dicapai dengan menggunakan fitur load-balancing yang terdapat di mikrotik routerboard 750. Dengan menggunakan teknologi database cluster diharapkan dapat mengatasi permasalahan yang terjadi di dalam system informasi.
