Judul: Designing The Experience of Freelance Lender on The Chain-lending Module of The Koper Pustaka Application
Abstrak: Budaya literasi masyarakat Indonesia masih tergolong rendah. Hal ini terjadi karena masyarakat kita yang masih erat dengan budaya lisan, sehingga menurunkan minat baca. Faktor pendorong rendahnya minat baca masyarakat yaitu, rendahnya daya beli yang didorong pula dengan minimnya sarana dan akses untuk menjangkau buku bacaan yang murah dan bervariasi. Berbagai inovasi dihadirkan oleh berbagai pihak dalam upaya meningkatkan minat baca masyarakat kita, salah satunya yaitu perpustakaan berbasis komunitas yang kemudian ditransformasikan ke dalam bentuk digital oleh Purnawansyah yaitu aplikasi Koper Pustaka. Penelitian ini bertujuan untuk merancang modul peminjaman berantai dari sisi pemberi pinjaman lepas dengan metode Design Thinking untuk menemukan alur yang efektif serta faktor engagement yang mampu membuat pengguna tetap ingin terlibat dalam komunitas aplikasi. Design Thinking dipilih karena bersifat user-centered yang mana cocok digunakan dalam menyelesaikan masalah berbasis pengalaman pengguna. Hasil akhir dari penelitian ini berupa prototipe mobile yang learnable yang telah diujikan kepada lima pengguna dengan usability testing. Dari hasil pengujian tersebut dapat disimpulkan flow yang dibuat mudah dipahami, serta ide yang dihadirkan telah meningkatkan excitement pengguna terhadap aplikasi Koper Pustaka., The literacy culture of Indonesian society is still relatively low because the community is closely related to oral culture, causing a lack of interest in reading. The driving factor of common public reading interest is low purchasing power because of the lack of facilities and access to cheap and varied reading books. Various parties made various innovations to increase our society's interest in reading. One of them is a community-based library transformed into digital form by Purnawansyah, named the Koper Pustaka application. This research aims to design a chain lending module from freelance lenders using The Design Thinking method to find an adequate flow and engagement factors to keep users engaged to the community. The Design Thinking method is user-centered, suitable for solving the problem based on user experience. The final result of this research is a learnable mobile prototype tested on five users using usability testing. The results obtained concluded that the flow is easy to understand. The ideas presented by Koper Pustaka have increased the excitement of the users towards this application.

Abstrak: Budaya literasi di Indonesia masih mencapai persentase yang terbilang rendah. Faktor yang menyebabkan hal tersebut yaitu keterbatasan akses penyebaran buku sebagai bahan bacaan. Salah satu bentuk inovasi yang telah dilakukan dalam upaya meningkatkan akses penyebaran buku yaitu dilakukannya penelitian sebelumnya berupa perancangan aplikasi pinjam meminjam buku secara berantai yang melibatkan pihak pemberi pinjaman dan juga pihak peminjam secara digital. Namun, penelitian tersebut hanya berfokus pada pengalaman dan faktor engagement dari sisi pemberi pinjaman saja. Berdasarkan keterbatasan tersebut, penelitian ini bertujuan untuk menghasilkan prototipe aplikasi mobile sistem peminjaman terikat dari sisi peminjam buku di aplikasi Koper Pustaka dan menemukan faktor engagement bagi peminjam terikat. Penelitian ini dirancang menggunakan metode Design Thinking. Hasil akhir dari penelitian ini berupa prototipe mobile berbasis pengalaman pengguna yang telah diujikan kepada lima pengguna dengan remote usability testing. Berdasarkan hasil uji, diperoleh nilai SEQ (Single Ease Question) sebesar 6,8 dari nilai tertinggi tertinggi yaitu 7 dan nilai SUS (System Usability of Scale) sebesar 93,5 dari nilai tertinggi yaitu 100. Dapat disimpulkan bahwa prototipe tampilan yang dibuat sudah memenuhi aspek learnability dan usability yang baik.

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.
