BloodChain: A Blood Donation Network Managed by Blockchain Technologies

Due to the rapid change of population structure, leading to lower birth rates and quick aging rates, the demand for blood supply is increasing significantly. In most countries, blood quality and origin are managed by blood management information systems, such as national authorities. Nevertheless, the traditional system has limitations in this field, such as a lack of detailed blood information, making it challenging to manage blood quality, supply, and demand. Hence, to solve these issues, this paper proposes a blockchain-based system called BloodChain, an improved system to support blood information management, providing more detailed information about blood, such as blood consumption and disposal. BloodChain exploits private blockchain techniques with a limited number of relatively fast and reliable participants, making them suitable for B2B (Business to Business) transactions. In this paper, we also develop a proposed system based on the architecture of Hyperledger Fabric. The evaluation of BloodChain is performed in several scenarios to prove our proposed model’s effectiveness.

Electronic Business-to-Business Marketplace Transformation in the Chemical Industry: Will the Second Wave Succeed Where the First has Failed?

The global chemical sales are expected to be worth over €6,000 bn by 2030 and this offers a very significant market size for businesses to be transacted electronically. It is generally believed that the first wave of the electronic business-to-business marketplace featured very strongly into the chemical industry sometime in the late 1990’s, but in just over a few years many of these electronic marketplaces started to close down or being merged with others, and later on they too disappeared from the chemical industry. Many of them had failed to sustain themselves in the marketplace and survived. From 2005 onwards, it became apparent that the second wave of electronic marketplaces started to enter the chemical industry again. Electronic marketplaces were being set up by chemical manufacturers and distributors, with many of them even setting up multiple web storefronts, to promote their products. This research will look into the chemical distribution market size, supply chain activities, as well as the various electronic marketplaces present in the chemical industry. The Author will investigate into the reasons why the first wave of chemical electronic marketplaces did not manage to sustain themselves in the market and the possible reasons for their failure. The types of electronic marketplaces during the second wave were investigated in great detail. What are the differences in the types of electronic platforms in the second wave and will they stand a chance to survive this time round, when many of them have failed in the first wave? This research will attempt to investigate the possible strategies through the digital marketplace, by both chemical manufacturers and distributors, in their effort to capture greater market share.

Key Factors for Measuring Value Co-Creation in the Industrial Service Ecosystem

Managing and measuring value co-creation in industrial services are emerging themes from the perspective of industry and scientific research. Thus, this chapter aims to review the literature in order to identify the criteria for value co-creation management and measuring used to measure value co-creation in the industrial service ecosystem. To achieve this goal, the authors conducted a systematic literature review and a content analysis of the portfolio resulting from the review. Based on the findings, eight criteria were listed for managing value co-creation in the B2B (business-to-business) services sector. In addition, they identified a lack of limited integration and interdependence between the criteria shown in the literature for cooperative service management among companies.

Vyaapaar – B2B Outsourcing Platform

The project is a responsive Web application that will allow businesses from a variety of industries to register, upload, and bid on projects. Businesses on this platform will provide their project requirements and budget, and other businesses in that domain will be able to bid on their quote and provide their business profile. The project owner can then award their project to the company that best meets their budget and requirements. The primary goal of this project is to provide opportunities for businesses to assist one another during these difficult times due to the COVID-19 Pandemic. This project provides registered businesses with a platform to outsource their projects at a reasonable cost with no or minimal workforce, and businesses that are out of business or trying to survive economically will be able to get enough business to sustain themselves by bidding and proposing to projects available on the Vyaapaar application's platform.

Penerapan Metode Six Sigma pada IKM Manufaktur Industri Pendukung (Supporting Industry) untuk Meminimalkan Jumlah Produk Cacat

Industri pendukung merupakan industri yang membuat barang dan jasa, menjual ke pasar bebas atau ke industri lain untuk mendukung produk akhir yang memiliki nilai tambah. Karakteristik industri pendukung adalah business to business, sehingga efisiensi proses produksi menjadi kunci daya saingnya. Proses produksi yang efisien dapat meminimalkan cacat sehingga biaya produksi dapat diperkecil. Penelitian ini mengkaji penerapan metode six sigma di industri pendukung yang memproduksi alat peraga pendidikan. Penelitian dilakukan di perusahaan dengan tingkat kecacatan hingga 8,10 % pada produk cermin kombinasi. Nilai sigma produk tersebut sebesar 3,71 yang menunjukan bahwa peluang untuk melakukan perbaikan proses masih sangat terbuka. Perbaikan proses dilakukan dengan menerapkan tahapan perbaikan DMAIC (Define–Measure–Analyze–Improve-Control). Pada tahap define diketahui yang menjadi cacat dominan adalah jenis cacat Shrink Mark, yaitu sebesar 31% dari keseluruhan jenis kecacatan produk. Penyebab terjadinya cacat tersebut adalah tidak adanya nilai setting parameter yang digunakan secara konsisten pada mesin injection molding. Melalui serangkaian eksperimen, penelitian ini menentukan nilai setting parameter yang dapat meminimalkan cacat jenis shrink mark. Faktor setting parameter terpilih adalah cooling time dan holding pressure dengan nilai masing masing selama 20 detik dan 105 MPa. Reject rate produk cermin kombinasi berhasil diminimalkan dan nilai sigma meningkat menjadi 4,13.
