Abstract

As  functional  food  oil,  red  fruit  (Pandanus  conoideus  Lam)  oil  has  been  believed  by  local community  to  threat  several  degenerative  diseases  like  cancer.  Red  fruit  oil  (RFO)  has commanded high price value in Indonesian market. Therefore, the objective of the present study was to  investigate several physico-chemical properties of RFO. Some parameters of RFO  obtained  from  hexane  and  chloroform  fractions  have  been  evaluated.  Such parameters include acid value, saponification value, anisidine value, conjugated dienes and trienes as well as p-anisidine value. Besides, absorptivity coefficient, fatty acid composition, and volatile compounds were also determined. Acid value and saponification value of RFO from chloroform fraction were higher than those in RFO from hexane fraction. In addition, RFO  in hexane  fraction has  the higher  iodine and anisidine values  than  that  in chloroform fraction. Hexane  is  the  best  solvent  to  be  used  for  analysis  of  RFO,  as  indicated  by  the highest  absorptivity  coefficient  of RFO  in hexane.  The main  fatty  acid  composed  of RFO was oleic acid  followed with palmitic acid. The main volatile compound present  in RFO of hexane and chloroform fractions was 9-octadecenoic acid accounting of 41.57 % and 65.06 %, respectively.

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

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

Abstract

This article focuses on the psycholinguistic study of the syntactic aspects of Dutch-Indonesian interlanguage. The study is based on the interlanguage syntax observed in an oral test given to thirty Indonesian learners of Dutch as a second language, whose purpose is to test the processability theory of Pienemann (2005a, b, c, 2007). The results of the study provide evidence for the validity of Pienemann’s theory. Learners who have acquired sentences with the highest level of processing will also already have acquired sentences with a lower level of processing. The results from learners with a high level of Dutch proficiency verify the processability theory with more certainty than the results of learners with a lower proficiency. Learners tend to rely on meaning if they are not confident of their grammatical proficiency. Interlanguage is the result of the immediate need to encode in the mind concepts and ideas into the form of linguistic items, within a fraction of a millisecond, whilst the supporting means are limited, and whilst learners already have acquired a first language and possibly another language as well.

Abstract

This study aims at (1) identifying the lingual form of disfemism in Joko Widodos Facebook account; (2) describing the addressing form containing sarcasm in Joko Widodos official Facebook account; and (3) identifying the sarcasm expression used by the operator and the uploader of the account. The object of this study is polite expressions. Linguistic unit of the expressions can be in the form of word, phrase, clause, and sentence. The data of this present study are sentence or sentences in Jokowis official Facebook account that contains positive connotation words. The data contexts of this research are discourse containing positive connotation sentences, the topic of discourse written by people in Jokowis account, the identity of the participant, and the context of extra-lingual that is based on the importance of the operator of the presidents social media account. The data collection was conducted through documentation technique. The data in Jokowis official account were copy-pasted. Then, the data were being read intensively to note the positive connotation utterance. The data analysis was conducted through referential (identity) method, pragmatic (identity) method, translational (identity) method, and articulatory phonetic (identity) method. The referential (identity) method was used to identify the topics that were stated by the uploader of the account. The pragmatic (identity) method was used to identify the background of (profession, organization etc) that appeared in their writings. The translational (identity) method was used in describing the origination of the language they use. It is possible that through the use of this method, this study finds the register on that account. Finally, the phonetic (identity) method was used to identify the utterance characteristic they stated. The positive or negative emotion of the speaker, usually, marked by the special pronunciation. To establish the data analysis, this study uses distributional method: substitution technique and paraphrase technique. Based on the data analysis, this study shows several results. First, the euphemism utterance in Jokowis official Facebook account using any levels, i.e. word, phrase, clause, and sentence. Through those levels, the writer presents suggestions and critics to the owner of the account Joko Widodo. Second, the functions that are stated through that account are expression device, communication relationship to the leader, integration device, and self-control device. Third, the topics stated by the people in that account are about the depiction of Joko Widodo that in their opinion, Joko Widodo shows pretending, the existence of Megawati in the election of Joko Widodo as a president, the increasing of IDR currency and other things at the beginning of his leadership. The expression shows hatred towards the elected president. Furthermore, they also express about Jokowis unability to establish the IDR currency and his leadership is judged as not good. In addition, to the people, especially netizen are invited to disbelieve to his leadership.
