Judul: Perancangan user experience KRB Apps menggunakan five planes user experience elements
Abstrak: Keterbatasan informasi lokasi objek wisata di Kebun Raya Bogor (KRB) membuat pengunjung kesulitan mencari rute menuju objek wisata. KRB Apps adalah aplikasi mobile yang membantu pengguna menemukan rute terpendek menuju objek wisata di KRB berdasarkan lokasi pengguna secara real-time. Penelitian ini berfokus pada pengembangan user experience (UX) menggunakan metode five plane user experience elements. Metode tersebut diawali dengan analisis kebutuhan pengguna dan tujuan bisnis stakeholder pada lapisan strategy plane. Penentuan fitur dan spesifikasi fungsional dilakukan pada lapisan scope plane. Hierarchical task analysis (HTA) digunakan dalam perancangan interaksi dan analisis task pada lapisan structure plane. Pembuatan prototipe low fidelity dan medium fidelity masing-masing dilakukan pada lapisan skeleton plane dan surface plane. Prototipe low fidelity dan medium fidelity dievaluasi menggunakan metode think-aloud evaluation. Berdasarkan hasil evaluasi tersebut, terdapat beberapa icon yang sulit dimengerti dan terdapat beberapa interaksi yang tidak sesuai dengan ekspektasi pengguna. Meskipun begitu, partisipan mengapresiasi tampilan visual prototipe dan pengalamannya pada saat menggunakan kedua metode navigasi (navigasi suara dan navigasi augmented reality) pada prototipe KRB Apps.

Judul: Perancangan Mobile User Experience Aplikasi Visit Puncak untuk Perkiraan Kunjungan Wisatawan Kawasan Puncak Kabupaten Bogor
Abstrak: Puncak visitors are expecting a pleasant tour experience without a jam. This expectation was restrained by the high-level traffic and less information about the good places in Puncak. Visit Puncak (VP) is a mobile application which is designed to estimate the density of Puncak visitors and serve the information about the destination in Puncak. This research focuses on mobile user experience (UX) design which was build using the wheel lifecycle based on Hartson-Pyla method. The lifecycle started with an analysis to understand user works and needs by doing an interview and observation involving 111 respondents. Design that is needed to determine interaction behavior and look and feel is done by creating a persona, storyboard, and scenario. Design results are implemented into a low-fidelity and medium-fidelity prototype. Overall, based on Nielsen heuristic evaluation, VP had meet the goals of usability. However, the usability problem about visibility of system status should be fixed before the app can be released.

Judul: Salinity influence to mercury toxicity and the effect to milkfish (Chanos chanos Forsskal) physiologic conditions
Abstrak: Mercury is a very dangerous heavy metal that can damage nerve and enzyme system in fish body. This research aimed to knows mercury toxicity to milkfish with different salinity. It consisted of two steps; they were preliminary research (range value test and acute toxicity test) and main research (the salinity influence of mercury toxicity and milkfish’s physiologic condition). Range value test was done in fresh water consisting of five treatments (0, 0.006, 0.06, 0.6 and 6 mg Hg/l). Acute toxicity test also consisted of five treatments (0, 0.110, 0.195, 0.347 and 0.618 mg Hg/l). Moreover, main research consisted of one control and three treatments with three replications at the same concentrate of mercury 0.012 mg Hg/l. Those treatments were salinity 0 ppt, 10 ppt and 20 ppt. The result demonstrated that LC50 96 hour in fresh water was 0.147 mg Hg/l. The main research showed that mercury can increased osmotic gradient, decreased oxygen consumption rate, increased blood glucose rate, decreased hematologic conditions, growth rate, feeding efficiency, and survival rate. Mercury is collected in body gland, for example in gill and liver. Treatment C (10 ppt) showed better physiologic conditions than other treatments. The effect of mercury toxicity would get minimal while maintained at optimal salinity.
