Judul: Design and Build a Blockchain-Based College Academic Information System
Abstrak: Pemanfaatan teknologi informasi dapat kita lihat pada bidang Pendidikan, yaitu Sistem Informasi Akademik (SIAKAD). Sistem Informasi Akademik adalah suatu sistem yang dirancang untuk keperluan pengelolaan data-data sehingga seluruh proses kegiatan akademik dapat dikelola menjadi informasi yang bermanfaat. Kondisi saat ini semua penyimpanan data disimpan pada sebuah database hal ini menimbulkan permasalahan yaitu sulitnya membackup data jika terjadi kerusakan dan menyulitkan saat melakukan validasi data karena tidak adanya verifikator saat melakukan input data. Maka dari itu solusi dari permasalahan tersebut adalah dengan menerapkan Teknologi Blockchain pada sistem akademik. Teknologi Blockchain adalah sebuah buku besar yang akan mencatat seluruh kegiatan yang dilakukan kemudian data akan didistribusikan kepada setiap node yang sudah ditentukan, sehingga setiap node akan memiliki salinan darisetiap transaksi. Transaksi yang dibuat adalah data nilai mahasiswa, data tersebut akan disimpan ke dalam blockchain. Pada penelitian ini sudah dirancang sebuah aplikasi sistem informasi akademik berbasis blockchain menggunakan metode prototype. Hasil dari penelitian ini adalah sebuah aplikasi sistem informasi blockchain yang dapat memverifikasi keaslian transkrip nilai dan melihat ketelusuran data nilai mahasiswa., Academic Information System (SIAKAD) is an application designed for data management purposes so that the entire process of academic activities can be managed into useful information. The current situation is that all the data are stored in a databases, which can cause problems, namely of backing up data and difficulty in validation. As we all know, students transcripts are needed for scholarships, applying jobs etc. Hence they need to be validated. Therefore, the purpose of this research is to design a blockchain-based SIAKAD application that can make it easier to check data to prove the authenticity ofstudent grade transcripts and display traceability of student grade data. Blockchain technology is a ledger that will record all activities carried out in this case the data that is recorded and stored into the blockchain is the value transcript data. data will be distributed to each node that has been determined, so that each node will have a copy of every transaction. The transactions made are student value data, the data will be stored into the blockchain. In this study, a blockchain-based academic information system application has been designed using the prototype method and then using the hyperledger fabric as a framework for building blockchain. The result of this research is a blockchain information system application that can verify the authenticity of grade transcripts and see traceability of student grade data.

Judul: Implementasi Teknologi Blockchain untuk Tracking Aset pada Aplikasi Koper Pustaka
Abstrak: Tingkat literasi baca-tulis masyarakat suatu negara merupakan salah satu hal yang sangat berpengaruh terhadap kemajuan negara tersebut. Namun, tingkat literasi masyarakat Indonesia masih tergolong rendah pada tahun 2019. Tantangan yang dihadapi adalah kurangnya minat membaca masyarakat yang menyebabkan belum maksimalnya budaya membaca. Salah satu inovasi yang dapat dilakukan untuk menghadapi tantangan ini adalah perpustakaan komunitas dengan konsep koper buku keliling, konsep ini memungkinkan masyarakat untuk meminjam buku yang sesuai dengan kebutuhan dan minatnya dengan mudah karena proses peminjaman terjadi langsung antar peminjam. Masalah yang dihadapi inovasi ini adalah bagaimana melacak dan memastikan keberadaan dan kondisi buku-buku yang ada. Penelitian ini berfokus dalam implementasi teknologi blockchain dalam sistem pendukung pelaksanaan perpustakaan komunitas berkonsep koper buku keliling yang berisi koleksi bacaan. Penelitian ini berhasil mengembangkan sistem yang mengimplementasikan jaringan blockchain dengan menggunakan Hyperledger Sawtooth, sistem ini dapat membantu pengguna untuk melakukan peminjaman koleksi bacaan dan dapat juga membantu untuk melacak dan memastikan kondisi dari koleksi bacaan tersebut., The literacy rate of the people of a country is one of the things that greatly influence the progress of the country. However, the literacy rate of the Indonesians is still relatively low in 2019. The challenge faced is the lack of interest in reading in the community which causes the reading culture not to be maximized. One of the innovations that can be done to face this challenge is a community library with the concept of a mobile bookcase, this concept allows people to borrow books that suit their needs and interests easily because the borrowing process occurs directly between borrowers. The problem facing this innovation is how to track and ensure the existence and condition of the existing books. This research focuses on implementing blockchain technology in a community library implementation support system with the concept of a traveling bookcase containing a collection of readings. This research has succeeded in developing a system that implements a blockchain network using Hyperledger Sawtooth, this system can help users to borrow reading collections and can also help to track and ensure the condition of the reading collection.

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
