Judul: Aktivitas Antimikroba Ekstrak Etanol Daun Jawer Kotok (Coleus atropurpureus) Terhadap Bakteri Kulit Wajah Berjerawat.
Abstrak: The misused of antibiotics will resist the bacteria. The increasing of resistance in antibiotic needs exploration other alternative resources which could kill or obstruct bacteria to grow. One of resources is jawer kotok (Coleus atropurpureus) leave. The objectives of this research are to assay jawer kotok leave’s etanol extract as antibacterial for pimpled skin. Those bacteria are Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus sp., and Micrococcus sp.. The bacterias were challenged with gradual extract consentration, starting from 20%, 40%, 60%, 80% and campared with 1% clindamycin antibiotic. The result of the research showed that jawer kotok leave’s etanol extract had potency as good antibacterial. The diameter of antibacterial inhibition zone range from 13.80 ± 1.09 mm until 17,00 ± 0,70 mm. Secondary metabolites in jawer kotok leave consist of flavonoids, polyphenols, tannins and terpenoids which had potency as antibacterial.

Judul: Uji Daya Hambat Ekstrak Etanol Kulit Batang Kayu Manis (Cinnamomum burmannii) Sebagai Antimikroba Terhadap Bakteri Pada Wajah.
Abstrak: Resistance of microorganisms to antimicrobial agent such as antibiotic makes treatment with antibiotic become ineffective, so it is necessary to develop alternative antimicrobial from plants. One of the herbs that have antimicrobial activity is cinnamon. The aim of this research was to compare the effectivity of cinnamon bark (Cinnamomum burmannii) ethanol extract at various concentrations with clindamycin in inhibiting the growth of Gram-positive cocci bacteria isolated from facial skin. The method used for in vitro antimicrobial inhibition test was agar well diffusion method. The test results showed that cinnamon bark extract has antimicrobial effectivity in inhibiting the growth of Gram-positive cocci bacteria but not as good as clindamycin. However, extract with concentration 20% and 40% in Micrococcus sp. showed better antimicrobial activity than clindamycin.

Judul: Analisis Struktur Atas Gedung Diploma IPB terhadap Beban Gempa Berdasarkan SNI 03-1726-2002 dan SNI 03-1726-2012
Abstrak: Gedung Diploma IPB masih menggunakan SNI 03-1726-2002 dalam perencanaan strukturnya. SNI tersebut kemudian diubah seiring dengan keluarnya peraturan baru yang termuat dalam SNI 03-1726-2012. Tujuan dari penelitian ini adalah mengetahui ketahanan struktur atas gedung Diploma IPB terhadap beban gempa ditinjau berdasarkan waktu getar alami dan partisipasi massa, mengetahui besarnya gaya geser dasar seismik, dan membandingkan besarnya simpangan berdasarkan kedua SNI. Partisipasi massa arah X yang dihasilkan yaitu sebesar 0.9417 pada modal ke 9 dan 0.9006 pada modal ke 12 pada arah Y. Kedua nilai tersebut telah memenuhi kedua standar SNI. Waktu getar alami telah memenuhi standar SNI 2002, namun belum memenuhi standar SNI 2012. Gaya geser dasar dinamik yang dihasilkan berdasarkan SNI 2012 sebesar 1599.6606 kN akibat gempa arah X dan 1223.5794 kN akibat gempa arah Y, sedangkan berdasarkan SNI 2002 untuk arah X sebesar 1544.5109 kN dan untuk arah Y sebesar 1544.8304 kN. Simpangan antar lantai telah memenuhi persyaratan kedua standar SNI. Struktur Gedung Diploma IPB telah memiliki kekakuan yang cukup dan terhitung boros, sehingga seharusnya dapat direncanakan dengan lebih hemat biaya.
