Judul: Perancangan Prototipe Antarmuka Olam International Mobile App Menggunakan Metode Lean UX.
Abstrak: Olam International menyadari bahwa para trader komoditas membutuhkan suatu aplikasi yang bisa memenuhi kebutuhan informasi dalam menentukan pembelian komoditas. Sehingga mereka ingin mengembangkan satu aplikasi yang memudahkan para trader dalam menentukan pembelian dan penjualan komoditas. Tujuan dari penelitian ini adalah merancang prototipe antarmuka Oltrade untuk Olam International yang memenuhi kebutuhan dengan memperhatikan aspek user experience. Penelitian ini menggunakan metode Lean UX yang terdiri dari 4 tahapan yaitu, Declare Assumptions, Create an Minimum Viable Product, Run an Experiment, dan Feedback and Research. Hasil dari prototipe ini sudah diuji kepada 5 responden dan mendapat nilai success rate sebesar 90% pada iterasi pertama. Pada iterasi kedua dilakukan pengujian parameter efektivitas dengan metode levels of success. Prototipe antarmuka Oltrade dikatakan efektif karena tidak ditemukan masalah mayor dan tidak ada responden yang menyerah/ gagal pada saat pengujian.

Judul: Perancangan User Experience Aplikasi Mobile Tokocabai dengan Metode Lean UX
Abstrak: Cabai merupakan komoditas pertanian di Indonesia yang memiliki produksi dan permintaan yang cukup tinggi, namun harga cabai di pasar seringkali mengalami fluktuasi harga yang menyebabkan kerugian di kalangan petani cabai. Teknologi informasi berupa marketplace dinilai dapat membantu petani dalam meningkatkan keuntungan penjualan komoditas pertanian khususnya cabai. Sebelumnya, marketplace Tokocabai sudah tersedia untuk versi web, namun untuk versi mobile belum tersedia. Penelitian ini bertujuan menghasilkan rancangan prototipe mobile user experience sistem Tokocabai yang sesuai dengan kebutuhan para praktisi dan pengguna. Metode Lean UX memiliki empat tahap cycle yaitu declare assumption, create an MVP, run an experiment, dan feedback and research. Penelitian ini dilakukan sebanyak dua iterasi, pada iterasi pertama pengujian dilakukan dengan usability testing terhadap lima orang responden, sedangkan pada iterasi kedua evaluasi dilakukan dengan heuristic evaluation on mobile interface. Pada iterasi pertama, hasil usability testing menunjukkan bahwa seluruh responden dapat menyelesaikan task yang diberikan, selain itu pada iterasi kedua, telah disajikan daftar evaluasi yang dapat dijadikan acuan perbaikan pada penelitian berikutnya. Hasil akhir penelitian ini berupa prototipe aplikasi mobile Tokocabai yang sudah disesuaikan bagi kebutuhan praktisi dan pengguna., Chili is an agricultural commodity in Indonesia which has a quite high production and demand, but chili prices in the market often experiences price fluctuations which cause losses among chili farmers. Marketplace is considered to be able to help farmers increase profits from selling agricultural commodities, especially chilies. Previously, the Tokocabai marketplace was available for the web version, but the mobile version is not yet available. This study aims to produce a mobile user experience prototype design for the Tokocabai system that suits the needs of practitioners and users. The Lean UX method has four cycle stages, namely declare assumption, create an MVP, run an experiment, and feedback and research. This research was conducted in two iterations, in the first iteration the test was carried out by usability testing on five respondents, while in the second iteration the evaluation was carried out by heuristic evaluation on mobile interface. In the first iteration, the results of usability testing showed that all respondents were able to complete the given task. In the second iteration, an evaluation list was presented which could be used as a reference for improvement in subsequent research. The final result of this research is a prototype of the Tokocabai mobile application that has been adapted to the needs of practitioners and users.

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.
