Judul: Perancangan Pengalaman Peminjam Lepas Aplikasi Koper Pustaka Menggunakan Metode Design Thinking
Abstrak: Koper Pustaka merupakan sarana untuk mempermudah melakukan peminjaman buku dan pengembalian buku yang disajikan dalam bentuk aplikasi mobile. Penelitian ini berfokus pada perancangan prototype dari sisi peminjam lepas dengan tujuan menemukan alur yang efektif, efisien dan learnable dalam proses pinjam-meminjam buku, serta mendapatkan faktor engagement yang membuat peminjam tetap bertahan pada komunitas aplikasi Koper Pustaka. Penelitian ini menggunakan metode Design Thinking. Hasil akhir penelitian ini berupa medium-fidelity prototype berbasis pengalaman pengguna dengan pengujian retrospective think aloud dan single ease question terhadap lima orang responden. Berdasarkan hasil uji iterasi pertama, terdapat satu task dengan memiliki rata-rata persentase keberhasilan sebesar 40%, durasi rata-rata waktu tercepat sebesar 14,56 detik, dan nilai skala single ease questions sebesar 6,78. Pada iterasi kedua, diperoleh persentase keberhasilan sebesar 100% untuk masing-masing task dengan rata-rata waktu tercepat 6,88 detik dan nilai skala single ease questions sebesar 6,98., Koper Pustaka is a tool to facilitate easy borrowing and returning books which is presented in the form of a mobile application. This research focuses on designing prototypes from the perspective of freelance borrowers with the aim of finding an effective, efficient and learnable flow in the process of borrowing and borrowing books, as well as obtaining engagement factors that make borrowers stay in the Koper Pustaka application community. This study uses the Design Thinking method. The final result of this study is a medium-fidelity prototype based on user experience with retrospective think aloud and single ease question testing of five respondents. Based on the results of the first iteration test, there was one task with an average success percentage of 40%, an average duration of the fastest time is 14,56 seconds, and a single ease questions scale value of 6,78. In the second iteration, a success percentage of 100% was obtained for each task with the fastest average time of 6,88 seconds and a single ease questions scale value of 6,98.

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: Methane Consumption (CH4) on Upland Rice Cultivation Under Micro Climate Cobdition With N Fertilizer Levels
Abstrak: Methane (CH4) is one of radiatively active trace gases or greenhouse gas, having strong absorbsivity to the infrared outgoing radiation emitted by the earth's surface, hence causing the warming of the atmosphere. Methane concentration in the atmosphere increases with a rate of about 12+1 ppbv/yr, or 36 Tg/yr. The increase of methane was predicted to have a significant impact on the earth's climate. The presence of 1.3 ppmv of methane in the atmosphere causes the globally average surface temperature 1.30C higher than it would be with no methane.
