Judul: "Improve": Application To Help Smartphone  Users Surfing Information In Non-fiction Books
Abstrak: Jumlah pengguna smartphone di Indonesia yang tinggi dan terus bertumbuh seharusnya dapat berpengaruh positif pada peningkatan minat membaca. Namun, berdasarkan survei yang dilakukan oleh Central Connecticut State University (2016) dan Programme for International Student Assessment (2018) menunjukan bahwa minat membaca masyarakat Indonesia secara umum cenderung masih rendah. Penelitian ini bertujuan untuk mengidentifikasi serta menciptakan solusi dari permasalahan pengguna smartphone dalam proses membaca buku nonfiksi dengan menggunakan pendekatan design thinking. Hasil dari penelitian ini menunjukan bahwa pelanggan memiliki beberapa masalah yaitu (1) Motivasi membaca buku yang tidak stabil; (2) Kehilangan motivasi membaca di pertengahan buku; (3) Malas membuat notes; (4) Sulit meluangkan waktu untuk membaca buku. Menanggapi permasalahan yang ada, Improve ditawarkan sebagai aplikasi yang dapat meningkatkan pengalaman pelanggan selama proses membaca buku nonfiksi. Berdasarkan hasil uji prototype ditemukan bahwa fitur-fitur yang terdapat pada prototype Improve dapat menjadi solusi bagi pelanggan.

Judul: Designing the User Experience of the Koper Pustaka Library Application Bound Loan Module Using the Design Thinking Method, Designing the User Experience of the Koper Pustaka Library Application Bound Loan Module Using the Design Thinking Method
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.
