Judul: Keanekaragaman Famili Asteraceae di Kawasan Kampus IPB Darmaga, Bogar
Abstrak: Asteraceae is the second larger family after Leguminosae. The diversity of species in this family could be assessed by morphological and anatomical characters. This research aims to study the diversity of family Asteraceae in Campus Area of IPB Darmaga, Bogor by describing their morphological character and anatomical character of stomata and trichome. Sampling was conducted in 12 locations in the area of green space by using the methode of exploration. Type of stomata and trichome were observed using whole mount method. The family of Asteraceae were found as many as 26 species, belonging to 24 genera and 8 tribe. Tricomes of family Asteraceae are unicellular glandular trichome, multicellular glandular trichome, and multicellular non glandular trichome. The most often found trichome was multicellular non glandular trichome. The type of stomata of observed species are anomocytic

Judul: Keanekaragaman Spesies Tumbuhan Langka dan Sebarannya di Kampus IPB Darmaga
Abstrak: Various vegetation cover in IPB Darmaga Campus makes this place has plenty kinds of plants including naturally and wildly grown plants. Some of the plants are included as rare plants species. The rare plants species are potential to be utilized as media for conservation education. However, there’s no research yet about those rare plants and its distribution in IPB Darmaga Campus. The purpose of this research was to identify, determine the distribution, and document the history of rare plants species in IPB Darmaga Campus. Based on this research, there were 30 rare plants species from 18 families. Dipterocarpaceae was recorded as the dominating family. These rare plants species were dominated by tree habitus and were distributed in the whole area of IPB Darmaga, but mostly found in Faculty of Forestry area. These species were mostly planted by lecturers and alumni of Faculty of Forestry, Bogor Agricultural University (IPB). The purpose is for collection and student learning media.

Judul: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
