Abstract

Synthesis  dibenzyl terephathalate were done through PET softdrinkbottles   degradation   by   refluxing   in   benzyl   alcohol   at   14~C temperature for 20, 24. and 28 hours in the presence  of zinc acetate catalyst. The result of degradation was purified  by recristalization in methanol and then melting point  (mp), FTIR, I H NMR spectra, and TLC spot were determined. The melting point of product degradation.for   28   hours  was  98-99  "c.  Based   FTIR  spectra   known  thatcompounds  of  product   degradation  have   OH,  C=O,  C-O,  CH,monosubstituted benzene, disubstituted benzene groups,  while on IH NMR spectra showed chemical shift at 8.2 ppm  (s, IO H of monosubtituted benzene), 7.5 ppm (s, 9 H consist of 4 H disubstituted benzene and 5 H of aromatic benzyl alcohol), 5.4 ppm  (s, 1 H from OH benzyl alcohol), 4.8 ppm (s, 4 H of methylene), and 2.9 ppm (s. 7H of other traces). The single spot ofTLC plate indicated that productdegradation for  28 hours might be a single compound. Based these characterization  concluded  that  compound  of product  degradation was dibenzyl terephthalate contains benzyl alcohol and other traces.

Abstract

Based on the analysis  of the field situation  there are some complaints by the elementary   students  to their  parents  that the  local  content  subject  of Javanese  literature   is  hard  to  learn  and  is  not  interesting   that  it  becomes something   frightening   them.   That  is  why  it  is  necessary   to  immediately found  the  way  out  that  it  is  fun  for  them  to  learn  the  subject.  Therefore, using  the  recent   advancement    of  science   and  technology   a  competence­ based  Javanese  literature   learning  through  the media  of Wayang  Kancil  are introduced.  The training  is organized  to answer  the following  questions:  (1) What  are  the  manifestations    of  the  competence-based    literature   learning through   the   media    of   Wayang    Kancil?   and   (2)   To   what   extent   the competence-based    literature   learning  through  the  media  of  Wayang  Kancil succeed   to  encourage    the   students   in  learning   the  subject   of  Javanese Literature?The  target  population   are  the  elementary  school  teachers  in Kulom Progo  regency  of  Y ogyakarta.   Each  of the  existing  subdistricts   sends  two teachers   that   the  total   participants    are  40  individuals.   The   activity   are centered    in    Sanggar    Kegiatan     Belajar    (SKB)    Kulon    Progo    (Dinas Pendidikan   Hall).  It  is conducted   using  the  method  of speech,  discussion, exercise,  and Wayang  Kancil  simulation.All  of  the  40  participants   are  able  to  practice  the  learning  process using the Wayang  Kancil.  It may be initiated  using  story telling  and also by singing  a  song.  They  succeed:   (1)  to  chose  or  create  an  interesting   story appropriate  with the need of the elementary  school  students,  (2) to make  use of the language  and various  messages  on good conduct  that are to transfer  to the  students   in  the   learning   process   through   the  media  of  the   Wayang Kancil,  and  (3) to  master  the  strategy  in selecting  the contextual   stories  in Kulon   Progo.   Subsequently,    the  participants    are:   (1)  well-motivated     in practicing  and doing  their job  with the media of the Wayang Kancil,  (2) with the pleasure  willing  to share their knowledge  and skills with their  colleagues in their  respective  districts,   (3) all of them  listen  the tutorial,  attending  the183184perform~nce    of.the   Way~ng   Kanc~1 and  in the  same  time  appreciating     it, (4) to  pr~ctlce    telh.ng   Kanc~l   story    III tu:n  using  the  media  of  the  Wayang Kancil,  (5! to  smg  Kancil  song,  Kancil  poem  reading  appropriate   with  the psyc.hoiogical developmen.t  ~f the .elementary school students,  (6) to practice p~aYlllg~he Wayan~  Kancil  III a SImple manner  without  any instrument,   but dlrec~ly III t~e learning  process,  (7) to organize  the simulation  of the Wayang Kancil learning.Key words: KBK, wayang kancil, Javanese literature

Abstract

Program  of  Entrepreneurship  Volunteer  is  aimed  to  prepare  the  graduate  ofJavanese Language  study Program of FBS UNY Yogyakarta to compete in the job field., T,o achieve marketable graduates, the study Program offers cooperation with partners to prepare.the students in writing literary works, managing studios, and literary magazines., .       , ' Process' M  volunteering is perfomed by giving provisions in the partners'  places.Joining students are chosen from Sanggar Sastra Lecture and selected based on talents ang motivations. The indicators of success for each student are making a title for short strory, jagading   lelembut,  and geguritan,   and able to make a planning of studio establishment ang literary magazine.The participants were  16. However, the active persons were  11. After following.volunteering process, there were eight short stories to publish. Moreover, it is better since, there was a short story being published by mass media entitled Dak  Coreng  Mangsi  Abang(Ari Yuliani). Of  some  geguritaris made  by the  students,  almost  all  of  them  can be. published in mass media. There are 15 titles of geguritan recommended to publish, that it can be sent to mass media However, six titles need corrections. Some of the geguritans published in Sempulur   magazine are Sudra,  Sempati    written by Agus Yuana Dirgantara and Sepi witten by Sri Suranti. Then, in the category og jagading lelembut there was seven titles and all of them are proper to publish. In other case, the effort of studio management and literary magazine  establishment  are still  in the  form of proposal  consulted to the partners.Key words:  written  skills, literary  magazine, and  entrepreneurship  volunteer.

Abstract

The hydration structures and dynamics of In3+ ion have been studied using classical Molecular Dinamics (MD) simulation. The best basis sets were optimized to construct the 2-bodies, 3-bodies correction equations, and analysis of the trajectory file of the simulation results in the form of the parameter of a solvation structure such as RDF, CND, ADF, and dynamic properties, namely the migration of water ligands between the hydration shells. The results showed that the hydration structure of the In3+ ion is In(H2O)93+ and In(H2O)63+, respectively. The geometric arrangement of In3+ hydration obtained through the simulation of classical Molecular Dynamics 2-bd MM 2-bd corrected 3-bd effect is octahedral, which agrees with experimental data and shows the importance of 3-bd correction. The exchange of H2O ligands between the first and second shell or vice versa was not observed during the classical Molecular Dynamics simulation process (2-body + 3-body potential). The hydration structure of In3+ in the first shell was relatively stable.

Abstract

The docking of the piperlongumine molecule and its derivatives has been carried out to find molecules that have the potential as anti-cancer. A total of 18 ligands were docked to the 2v5z protein using the autodock4 and autodock vina programs. The binding energies of piperlongumine and piperlongumine derivatives [R1 = CH3 and R2 = H] were -8.6 kcal/mol and -9.3 kcal/mol, respectively. Based on molecular dynamics simulations, the hydrogen bond interaction fraction was dominated by GLN 206 residue in both the SAG (88%)  and piperlongumine derivatives ((R1=CH3, R2 = H)(93%) ligand, for this reason, this piperlongumine derivative molecule is predicted to have potential as MAO B inhibitor.
