Non-fungible tokens (NFTs) are a technological innovation that has been widely used to provide a form of digital reward. However, the application of NFTs in the social domain, especially in blood donation programs, has not been widely explored. This research aims to develop an NFT-based reward system using blockchain technology as an appreciation for blood donors. The system is designed and developed using the Ethereum test network due to its stability in decentralized applications. This research uses the research and development (R&D) method with the 4D model approach, which consists of the Define, Design, Develop, and Disseminate stages. In the Define stage, a needs analysis was conducted to determine the system specifications. The Design stage involves the design of a web-based system3 to support NFT management. In the Develop stage, the system was developed using the Ethereum testing network. The Disseminate stage includes system testing using the black box method to ensure that all key features, such as NFT claims and data transparency, function properly. The result of the research is an NFT-based blockchain application that allows blood donors to easily claim their NFTs as a form of digital recognition. The evaluation showed an acceptability score of 61.34%, indicating that this application is acceptable to the community and has the potential to increase blood donor motivation. The implementation of this system is expected to have a sustainable positive impact on increasing blood donor participation in the future.
Bitcoin is one of the most valuable crypto currencies among other crypto currencies. However, the legality of Bitcoin itself has not been recognized by Indonesia and many other countries as a legal tender, but it is allowed to be used as an investment asset. In the midst of the price of Bitcoin and its very high popularity, a sudden decline occurred after the discovery of a new variant of the Covid-19 virus. This study aims to find out about the cause of the fall in the value of Bitcoin after the establishment of the new Omicron Covid-19 variant as a variant that all countries in the world must be wary of. This research is a Library Research type with data sources in the form of news published by CNBC Indonesia on December 5, 2021, using the content analysis method. The conclusion of this study is that the fall in the price of Bitcoin was caused by the fear of shareholders and other high-risk assets due to news about the possibility of a lockdown in various countries, so these investors released their risky assets, including Bitcoin as a new asset which is still experiencing very high volatility so it is considered risky.
The COVID-19 outbreak had a severe impact on almost all countries in the world. One aspect of concern during the pandemic is an investment. In this study, the GARCH model used to estimate Value at Risk (VaR) on cryptocurrency investments as a tolerable loss during the COVID-19 pandemic. Data in this study are ten cryptocurrencies with the largest capitalization. The observation period when WHO declared COVID-19 as a pandemic, namely on March 11, 2020 - June 11, 2020. From this study, the highest cryptocurrency VaR value is Crypto.com with an amount of 0,18214. It means that the maximum loss that an investor can tolerate with an investment of $500.000.000 for a 95 percent confidence level is $ 91.070.392.

This article discusses two important studies. First, the way the Kalibeber Wonosobo community handles waste. Second, the model of waste management in the Kalibeber Wonosobo group. This research uses a Participatory Action Research approach. This approach involves the Kalibeber community as an object and subject as well as to deal with waste. The results of this study show two important scopes. First, the Kalibeber Wonosobo community has an initiative to deal with waste. The initiative emerged because the community felt the environment was dirty, the river water flow was obstructed, and many sufferers of itching. Second, the waste management model uses decentralization. Waste management is carried out in each sub-area to be able to reuse waste (recycling). This discourse is different from other studies. The most prominent differentiating side is the active role of the community by being able to separate organic and inorganic waste. The community operates independently with a voluntary financing mechanism.Artikel ini membahas dua kajian penting. Pertama, cara masyarakat Kalibeber Wonosobo menangani sampah. Kedua, model pengelolaan sampah kelompok paguyuban peduli sampah Kalibeber Wonosobo. Penelitian ini menggunakan pendekatan Participatory Action Research. Pendekatan ini melibatkan masyarakat kalibeber sebagai obyek dan subyek sekaligus untuk menangani sampah. Hasil penelitian ini menunjukan dua cakupan penting. Pertama, masyarakat Kalibeber Wonosobo memiliki inisiatif untuk menangani sampah. Inisiatif muncul karena masyarakat merasakan lingkungan kotor, aliran air sungai terhambat, dan banyak penderita penyakit gatal-gatal. Kedua, model pengelolaan sampah menggunakan desentralisasi. Pengelolahan sampah ini dilakukan pada setiap sub area untuk bisa memanfaatkan kembali sampah (daur ulang). Diskursus ini berbeda dengan kajian lain. Sisi pembeda yang paling menonjol, antara lain peran masyarakat yang aktif dengan mampu memisahkan sampah organik dan anorganik. Masyarakat bergerak mandiri dengan mekanisme pembiayaan secara sukarela.
