Judul: Perancangan Usability Sistem Visualisasi Keterkaitan Subjek Tesis Berbasis Web
Abstrak: Visualisasi data dengan beragam keunggulannya dapat menjadi solusi untuk memperoleh putusan informasi lebih cepat yang kerap kali dituntut pada institusi pendidikan. Penerapan teknik visualisasi data telah dilakukan terhadap data keterkaitan subjek karya ilmiah pada data tesis perpustakaan Institut Pertanian Bogor (IPB) melalui sistem Subject Term Relationship Visualization (STRV). Unsur interaksi manusia dan komputer dalam sistem tersebut belum diterapkan. Penelitian ini bertujuan meningkatkan unsur tersebut terutama komponen learnability dan memorable dengan membuat prototipe sistem melalui pendekatan user experience. Metode yang digunakan dalam penelitian ini adalah metode Wilson. Hasil yang diperoleh melalui penelitian ini adalah prototipe medium fidelity sebagai saran perbaikan sistem agar pengguna dapat mencapai tujuannya dengan lebih mudah. Evaluasi dilakukan dengan menggunakan menjawab 16 pernyataan visualization-specific heuristic evaluation. Hasil pengujian menunjukkan bahwa prototipe sistem telah berhasil meningkatkan komponen learnability dan memorable pada sistem.

Judul: Visualisasi keterhubungan antaristilah subjek pada metadata tesis IPB menggunakan peluang bersyarat
Abstrak: Bogor Agricultural University library has metadata for its collection. The metadata is used for searching and browsing. The activity of searching and browsing can be based on metadata fields, such as title, author, subject, etc. Searching on the subject or topic is an effective way if someone want to search document that fulfill his/her topic. When someone search on a subject, the result is only documents that has the subject. So, someone needs to pick an appropriate query to find the desirable result. The decision for picking a query is based on how good the knowledge of someone about the collection. It will be hard if someone does not know about the collection. In that case, we need an application that shows the relationship between the subject, so the related terms can be used as query suggestion for someone to decide his/her query. In order to make the view of relationship more interesting, understandable, and interactive, the relationship is visualized. The result of this research is an implementation of a Java desktop application that searches document based on subject and visualize subject terms relationship. The documents are from IPB thesis metadata. From 7445 documents, 7416 documents has subject field. Obtained 4496 unique terms from the 7416 document. From test result, the process to show document result and visualization is fast enough. The average time to show document result and visualization is one second.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
