Abstract

Telah dilakukan sintesis senyawa baru dengan reaksi klorinasi vanilin yang bertujuan untuk menghasilkan vanilin terklorinasi sebagai bahan dasar dalam sintesis analog kurkumin dengan substituen –Cl pada inti aromatiknya. Senyawa ini telah dilakukan elusidasi strukturnya. Reaksi klorinasi vanilin dilakukan dengan gas Cl2, yang merupakan hasil reaksi dari kaporit dengan asam klorida pekat. Reaksi ini berlangsung pada temperatur 35ºC selama 30 menit dalam katalis AlCl3 dan digunakan THF sebagai pelarut. Kemurnian senyawa hasil sintesis ditentukan berdasarkan titik leburnya serta kromatografi lapis tipis. Identifikasi struktur senyawa hasil sintesis dilakukan menggunakan teknik spektrometri, meliputi spektra UV–Vis, spektra inframerah (cm-1, KBr) dan spektra resonansi megnetik inti proton (_, ppm, DMSO–d6, 1H–NMR, 500 MHz). Reaksi klorinasi vanilin menghasilkan 4–hidroksi–5–kloro–3–metoksibenzaldehid yang berwarna kuning, dengan titik lebur 163,3–164,8ºC. Rendemen rata–rata yang dihasilkan sebesar 40,54 %.

Abstract

Cervical cancer is a type of cancer possessing the 3rd highest incidence among women worldwide. Todays therapies against cancer are still ineffective, thus people are seeking for alternative method. Erythrina fusca Lour. has been used traditionally as anticancer. This experiment is conducted to study the ability of chloroform extract of E.fusca Lour. leaves and its isolates on HeLa cervical cancer cells. The cytotoxicity assay and doubling time assay were done using direct counting method, while the DNA staining assay was done using acrydine orange. The chloroform extract and isolate #30 showed cytotoxic activity with IC50 of 16 and 5 μg/ml, respectively, while isolate #2 and isolate #8 didnt. The effluent #30 could not affect HeLa cells growth at the given concentration, but it might promote DNA fragmentation indicating apoptosis induction. The molecular mechanisme underlying these effects still need to be further explored.Keywords :  Erythrina fusca Lour., isolate and effluent of chloroform extract, antiproliferative, cervical cancer

Abstract

The study aims to describe the violations by the students of the 2014 initiation at UMS and identify their solutions by the activity coordinators and line coordinators. The primary data included the verbal abuse by the coordinators, committees, and students’ responses to the 2014 Academic Program Activity of Teacher and Training Education Faculty - UMS. The secondary data included the non-verbal (physical) abuse obtained from observation and interview. The data were collected through observation, inter-view and written documentation which include the results of the verbal and non-verbal strictness observation, summary of the initiation program and its regulation, and photos. The data validity used was data and data source triangulation. The data were analyzed using case study technique. The results of the study showed that there were some violations by the students during the initiation program as follows: (1) smoking a cigarette, (2) wearing a short skirt for the female, (3) wearing a transparent and tight cloth for the female, (4) not wearing a complete attribute, (5) speaking unethically or using four lette-words, (6) having a long hair beyond the ears, and (7) coming late. The solutions to the violations seemed that the line coordinators tended to permit them and they did not give any punishment so that the students kept on behaving badly. Some students thought that the team of the line coordinators were linient, particularly in giving punishment to the students who violated the regulations of the initiation program.

Abstract

Murraya paniculata [L.] Jack. merupakan tanaman yang tumbuh di Indonesia, dikenal dengan nama Kemuning. Penelitian mengenai tanaman ini telah banyak dilakukan, terutama isolasi senyawa aktifnya. Tanaman ini mempunyai kandungan senyawa aktif, diantaranya senyawa turunan flavonoid. Pada penelitian, tiga senyawa flavonoid yang diisolasi dari M. paniculata diuji aktivitasnya terhadap pelepasan histamin dari kultur sel mast yaitu sel RBL-2H3. Ketiga senyawa tersebut adalah 3,3’,4’,5,5’,7–heksametoksiflavon; 3,3’,4’,5,5’,6,7-heptametoksiflavon; dan 3,3’,4’,5,5’,6,7,8-oktametoksiflavon. Induktor pelepasan histamin yang digunakan adalah DNP24-BSA dan thapsigargin. Keduanya berturut-turut menginduksi secara imunologis dan non-imunologis. Hasil penelitian menunjukkan bahwa senyawa heptametoksiflavon dan heksametoksiflavon cenderung tidak mempengaruhi pelepasan histamin dari sel mast. Namun, oktametoksiflavon dapat meningkatkan pelepasan histamin dari sel mast baik tanpa induksi maupun terinduksi dengan DNP24-BSA atau thapsigargin. Senyawa tersebut mampun meningkatkan pelepasan histamin hingga 50%. Dari hasil tersebut, penambahan gugus polimetoksi pada struktur flavonoid berpotensi dapat menghasilkan efek pelepasan histamin dari sel mast.

Abstract. Cultural heritage is an asset owned by any country that can tell behavior of people’s life there. The story of the cultural heritage – one of them contained in archaeological object – is a story that have historical value and can not be replaced so we need to make the right efforts to conserve them, such as documenting the archaeological object we have, in this case is Sewu Temple Complex in Klaten, Central of Java. Conservation mean as branch of archeology that tries to preserve and manage archeological object to a lot of academic-practical interest (Yuwono, 2003). Geographic Information System that have storing, showing, and analyzing data ability, in the scope of conservation can used by archeologist for conserve or reconstruction. Principle of the development of virtual reality GIS for cultural heritage conservation is more directed to the terms of visualization. The several stage of this study are design the spatial database, data extraction – includes 3D modeling, 3D model georeferencing, 3D model segmentation, database implementation, and visualization process. The expectation result for this virtual reality GIS is an application that will represent 3-D visualization of Sewu Temple area, 3D models of each part of temple at LOD 2, LOD 3, until LOD 4. Beside that the application can be used for Temple reconstruction for more efficiently and effectively process. Keywords : Database, Virtual Reality GIS, Conservation, 3D Models
