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: Perancangan Pengalaman Pemberi Pinjaman Terikat pada Aplikasi Koper Pustaka Modul Peminjaman Berantai
Abstrak: Masyarakat yang gemar membaca akan membentuk sumber daya manusia yang berkualitas bagi bangsa. Namun, minat baca masyarakat Indonesia masih tergolong rendah. Hal ini disebabkan oleh rendahnya daya beli masyarakat. Salah satu inovasi yang dilakukan dalam upaya peningkatan minat baca Indonesia adalah perpustakaan dengan metode meminjamkan buku melalui koper dan tas pustaka telah dikembangkan dalam bentuk digital oleh Purnawansyah. Namun, masih ada beberapa masalah seperti pustakawan yang sering kehilangan buku dan juga masih terlibatnya pustakawan pada setiap perpindahan buku antar peminjam. Penelitian ini bertujuan untuk menghasilkan prototipe aplikasi mobile untuk sistem peminjaman berantai dari peran pemberi pinjaman terikat pada aplikasi Koper Pustaka dan menemukan faktor engagement bagi pemberi pinjaman terikat. Hasil dari penelitian ini berupa prototipe mobile berbasis pengalaman pengguna menggunakan metode Design Thinking yang telah diujikan kepada lima pengguna dengan usability testing. Berdasarkan hasil pengujian, diperoleh persentase kesuksesan sebesar 100% dan nilai System Usability of Scale sebesar 93,5. Dapat disimpulkan bahwa prototipe yang dikembangkan memiliki usability yang baik dan memenuhi aspek learnability dari pengguna., People who like to read will form good quality human resources for the nation. However, the reading interest of Indonesians is still relatively low. This is due to the low purchasing power of the community. One of the innovations made in an effort to increase Indonesia's reading interest is by lending books through suitcases and library bags to people, has been developed in digital form by Purnawansyah. However, there are still some problems, such as librarians who often lose books, and also the librarian is still involved in every book transfer between book lenders. This study aims to produce a mobile application prototype for a chain lending system from the tied lender's side to the Koper Pustaka application and to find engagement factors for tied lenders. The result of this research is a mobile prototype based on user experience using the Design Thinking method tested to five users using usability testing. The test results obtained a 100% success rate and 93,5 for System Usability of Scale score. This research can conclude that the prototype has good usability and already fulfils user’s learnability aspect.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
