Perancangan Smart Food Container dalam Sektor Rumah Tangga dengan pendekatan Desain Interaksi

Sektor rumah tangga merupakan kontributor sampah terbesar di Indonesia pada tahun 2018, sebesar 48%. Upaya pemerintah untuk mengatasi permasalahan sampah makanan masih berlangsung hingga saat ini. Salah satu alternatif yang dapat dilakukan yaitu dengan pengelolaan bahan makanan menggunakan konsep produk pintar. Oleh karena itu, penelitian dilakukan untuk merancang smart food container yang membantu pengguna untuk mengelola penggunaan bahan makanan di kulkas. Metode yang digunakan dalam perancangan smart food container ini adalah desain interaksi. Identifikasi kebutuhan dengan observasi dan wawancara menghasilkan tiga belas daftar kebutuhan terkait smart food container. Perancangan alternatif konsep dilakukan dengan membuat dua konsep berupa wadah yang fleksibel dan memiliki indikator waktu dan suhu. Konsep terpilih diperbaiki dan dilanjutkan ke tahap prototipe. Prototipe dibuat dalam bentuk prototipe tingkat rendah dan dapat menunjukkan interaksi antara pengguna dengan prototipe. Prototipe kemudian dievaluasi terkait tiga aspek, yaitu efektivitas, efisiensi, dan usability. Berdasarkan penelitian yang telah dilakukan, didapatkan hasil berupa prototipe smart food container yang terdiri dari 2 bagian produk, yaitu wadah dan indikator waktu dan suhu. Hasil dari evaluasi menghasilkan nilai efektivitas sebesar 89,09%, nilai efisiensi sebesar 78,18%, dan nilai System Usability Scale (SUS) sebesar 81, yang dapat diartikan bahwa rancangan smart food container tergolong dapat digunakan dengan baik. Terdapat juga perbaikan prototipe seperti perubahan tombol dan tampilan indikator pada indikator waktu dan suhu

A population search filter for hard-to-reach populations increased search efficiency for a systematic review

Objective: This paper discusses how hard-to-reach population groups were conceptualised into a search filter. The objectives of this paper are: 1) to discuss how the authors designed a multi-stranded population search filter and, 2) to retrospectively test the effectiveness of the search filter in capturing all relevant populations (e.g. homeless people, immigrants, substance misusers) in a public health systematic review. Study design and setting: Systematic and retrospective analysis via case-study. Retrospective analysis of the search filter was conducted by comparing the MEDLINE search results retrieved without using the search filter against those retrieved with the search filter. 5465 additional results from the unfiltered search were screened to the same criteria as the filtered search. Results: No additional populations were identified in the unfiltered sample. The search filter reduced the volume of MEDLINE hits to screen by 64% with no impact on inclusion of populations. Conclusion: The results demonstrate the effectiveness of the filter in capturing all relevant UK populations for the review. This suggests that well planned search filters can be written for reviews which analyse imprecisely defined population groups. This filter could be used in topic areas of associated co-morbidities, for rapid clinical searches, or for investigating hard-to-reach populations

A real-time, quantitative PCR method using hydrolysis probes for the monitoring of Plasmodium falciparum load in experimentally infected human volunteers

Background: The accurate quantification of Plasmodium falciparum parasite numbers by PCR is an important tool for monitoring growth kinetics in subjects infected and subsequently treated with anti-malarial agents

Strand separation establishes a sustained lock at the Tus-Ter replication fork barrier

The bidirectional replication of a circular chromosome by many bacteria necessitates proper termination to avoid the head-on collision of the opposing replisomes. In Escherichia coli, replisome progression beyond the termination site is prevented by Tus proteins bound to asymmetric Ter sites. Structural evidence indicates that strand separation on the blocking (nonpermissive) side of Tus-Ter triggers roadblock formation, but biochemical evidence also suggests roles for protein-protein interactions. Here DNA unzipping experiments demonstrate that nonpermissively oriented Tus-Ter forms a tight lock in the absence of replicative proteins, whereas permissively oriented Tus-Ter allows nearly unhindered strand separation. Quantifying the lock strength reveals the existence of several intermediate lock states that are impacted by mutations in the lock domain but not by mutations in the DNA-binding domain. Lock formation is highly specific and exceeds reported in vivo efficiencies. We postulate that protein-protein interactions may actually hinder, rather than promote, proper lock formation
