Judul: Trend desain penanaman pada lanskap permukiman Bogor Nirwana Residence
Abstrak: Bogor Nirwana Residence (BNR) is a housing estate in Bogor city which has nature concept. Each area in BNR has different planting design trends which are interesting to be studied. The objectives of this study were to identify plants diversity and elements of planting design, to analyze planting design trends and to propose a recommendation of planting design concept for residential landscape of BNR. Method used in this study was survey method with descriptive analysis, which consisted of site inventory, analysis and synthesis stage (arranging recommendation). This study focused on plants dominants, species diversity, functional and aesthetic aspects of the plant arrangements. Results of the study showed that there were 128 species of plants in the whole area of study. The diversity varied from 0,07 to 1,1. Plant types which had highest dominant scores were trees on the main road and groundcovers on cluster gates, public parks and fronthouse gardens. Functional aspects scores on main road classified into poor with score 58,6%, while public park classified into fair with score 63,8%. Aesthetic aspects scores on whole area of study classified into fair, varied from 64,4% to 75,6%. Recommendation of planting design concept was made following ideal criteria of required functional aspects on each area of study.

Judul: Trend Tata Hijau Pada Lanskap Permukiman The Springs Summarecon Serpong
Abstrak: The human needs about residential is increasing. Hence there are many new residential appear, one of which is The Springs Summarecon Serpong. The main purpose of this research was to indetify the vegetation diversity and analyze the trend of planting plan that used in the residential landscape of The Springs Summarecon Serpong. The research was also aimed to draw up recommendation of planting design. Vegetation data is collected from some of the areas of study, which is: main gate, main roads, cluster gate, neighborhood roads, neighborhood park, and home garden . The parameters of vegetation that analyzed like density, dominance, frequency, Shanon diversity index and arrangements of plants. In addition, the aspect of function and aesthetic of vegetation analyzed by comparing the conditions in the field with the criteria of ideal that was obtained from the study of literature. These results indicate that Zoysia matrella is a species that has a highest value of density, dominance, and frequency in area of study locations. Overall diversity index in area of study locations including moderate at 1.4. The highest diversity found in the neighborhood park area that is equal to 1.86. The value of the function and aesthetic aspects on the whole area of study sites included in good category. Planting arrangement in this residential landscape using the open park style and much use of grass. The arrangement of plants using organic patterns to increase natural impression in most areas of study locations.

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%.
