Difficulty in inventory management on space station has been known since 1980’s but still is a new problem. We propose the expanded application of IC tags for the International Space Station inventory management. Use of multiple RFID tags can monitor package use status. Where electromagnetic interference or poor radio propagation is a problem, we may apply ultrasound tags.

Banyak instansi khususnya sekolah masih menganggap manajemen aset secara fisik hanyalah sekedar instrumen pengelolaan daftar aset. Realita di lapangan menunjukan banyak kasus yang sebenarnya dimulai dari salah kelola dan salah urus masalah aset; sehingga berdampak kerugian yang tidak sedikit. Manajemen aset adalah serangkaian kegiatan yang terdiri dari indentifikasi aset apa yang dibutuhkan; memperoleh  aset; menyediakan logistic dan sistem pendukung pemeliharaan dari asset dan penghapusan atau pembaharuan asset sehingga lebih efektif dan efisien. Untuk mempercepat dan memudahkan  bagi pengguna di sekolah dalam memanajemen aset sekolah diperlukan fitur tambahan yaitu RFID (Radio-Frequency Identification) adalah sistem identifikasi tanpa kabel yang memungkinkan pengambilan data tanpa harus bersentuhan. Prototipe adalah pengembangan yang cepat dan pengujian terhadap model kerja prototipe dari aplikasi baru melalui proses interaksi dan berulang-ulang yang biasa digunakan ahli sistem informasi dan ahli bisnis. Prototipe disebut juga desain aplikasi cepat (rapid application design atau RAD) karena menyederhanakan dan mempercepat desain sistem. Dengan adanya sistem manajemen aset yang baru; modern; sistematis; valid dan real time dapat memudah pekerjaan mengelola aset sekolah dengan baik dan benar; dan dapat meminimalisir kerugian yang terjadi akibat kesalahan dalam pengelolaan Aset di sekolah.

For the past two decades, microbial monitoring of the International Space Station (ISS) has relied on culture-dependent methods that require return to Earth for analysis. This has a number of limitations, with the most significant being bias towards the detection of culturable organisms and the inherent delay between sample collection and ground-based analysis. In recent years, portable and easy-to-use molecular-based tools, such as Oxford Nanopore Technologies’ MinION™ sequencer and miniPCR bio’s miniPCR™ thermal cycler, have been validated onboard the ISS. Here, we report on the development, validation, and implementation of a swab-to-sequencer method that provides a culture-independent solution to real-time microbial profiling onboard the ISS. Method development focused on analysis of swabs collected in a low-biomass environment with limited facility resources and stringent controls on allowed processes and reagents. ISS-optimized procedures included enzymatic DNA extraction from a swab tip, bead-based purifications, altered buffers, and the use of miniPCR and the MinION. Validation was conducted through extensive ground-based assessments comparing current standard culture-dependent and newly developed culture-independent methods. Similar microbial distributions were observed between the two methods; however, as expected, the culture-independent data revealed microbial profiles with greater diversity. Protocol optimization and verification was established during NASA Extreme Environment Mission Operations (NEEMO) analog missions 21 and 22, respectively. Unique microbial profiles obtained from analog testing validated the swab-to-sequencer method in an extreme environment. Finally, four independent swab-to-sequencer experiments were conducted onboard the ISS by two crewmembers. Microorganisms identified from ISS swabs were consistent with historical culture-based data, and primarily consisted of commonly observed human-associated microbes. This simplified method has been streamlined for high ease-of-use for a non-trained crew to complete in an extreme environment, thereby enabling environmental and human health diagnostics in real-time as future missions take us beyond low-Earth orbit.
