Exploring EFL Students' Strategies in Writing Research Background at One of the Universities in Cirebon

Learning strategies assist students in revealing their individual learning style, recognizing their identity as “learners”, and being conscious of their learning obstacles. The current study aimed to investigate the strategies in writing research background encountered by English Department students at one of Cirebon’s institutions throughout the academic year 2021/2022. This study employed a qualitative technique with a case study design, with thirty students participating as respondents. The data was gathered via a questionnaire and an interview. There are two research instruments in this research, especially close-ended questionnaire and semi-structured interview.The instruments were also distributed in Bahasa Indonesia. According to the findings, students adopted strategies such as reviewing the references of journal articles. This causes students to use strategies to reduce these difficulties, including reading reference journals or articles. The score using this strategy is 95%.  Furthermore, respondents indicated that they were requesting revisions from their supervisor.This is the experience of lecturers were better because they have done research many times. As a result, they were changing the sentence structure check.In addition, it creates sentences that are difficult to understand between sentences and paragraphs that are out of sync. There was a need for a revision of the review to produce a coherent reading and not confused the readers.It is suggested that the students choose the appropriate strategy, so that the strategy can be implemented properly

Enhancing Students’ Writing Ability and Creativity through Project Based Learning on Greeting Card

This study focuses on the implementation of Project Based Learning (PjBL) in writing greeting card to enhance students’ writing ability and creativity. It is based on the classroom action research at the eighth grade of SMPN 1 Sumber, Cirebon, in the academic year of 2019/2020. The subject of the study were 32 students, they were 16 females and 16 males. This study was conducted into two cycles, and each cycle consisted of two meetings. The data were taken qualitatively and quantitatively. Qualitative data were taken from classroom observation, interview and pictures documentation. While quantitative data were taken from the writing test, including the students’ score on pre-test and post-test in each cycle. The findings showed that the use of PBL was able to enhance students’ writing ability. The implementation of PjBL strengthened students’ creativity since it enabled students to explore themselves while developing the greeting card. They were enthusiastic and active in participating during the teaching and learning process of writing. The findings showed that the students’ mean score in the pre-test was 67,8 and it increased to 94,15 in their post-test with the gain score 26,35, which indicated that the improvement was very significant

Variable coordination of amine functionalised N-heterocyclic carbene ligands to Ru, Rh and Rr: C-H and N-H activation and catalytic transfer hydrogenation

Chelating amine and amido complexes of late transition metals are highly valuable bifunctional catalysts in organic synthesis, but complexes of bidentate amine–NHC and amido–NHC ligands are scarce. Hence, we report the reactions of a secondary-amine functionalised imidazolium salt 2a and a primary-amine functionalised imidazolium salt 2b with [( p -cymene)RuCl 2 ] 2 and [Cp*MCl 2 ] 2 (M = Rh, Ir). Treating 2a with [Cp*MCl 2 ] 2 and NaOAc gave the cyclometallated compounds Cp*M(C,C)I (M = Rh, 3 ;M = Ir, 4 ), resulting from aromatic C–H activation. In contrast, treating 2b with [( p -cymene)RuCl 2 ] 2 ,Ag 2 O and KI gave the amine–NHC complex [( p -cymene)Ru(C,NH 2 )I]I ( 5 ). The reaction of 2b with [Cp*MCl 2 ] 2 (M = Rh, Ir), NaO t Bu and KI gave the amine–NHC complex [Cp*Rh(NH 2 )I]I ( 6 ) or the amido–NHC complex Cp*Ir(C,NH)I ( 7 ); both protonation states of the Ir complex could be accessed: treating 7 with trifluoroacetic acid gave the amine–NHC complex [Cp*Ir(C,NH 2 )I][CF 3 CO 2 ]( 8 ). These are the first primary amine– or amido–NHC complexes of Rh and Ir. Solid-state structures of the complexes 3–8 have been determined by single crystal X-ray diffraction. Complexes 5 , 6 and 7 are pre-catalysts for the catalytic transfer hydrogenation of acetophenone to 1-phenylethanol, with ruthenium complex 5 demonstrating especially high reactivity

The Implementation Of Digital Resources As Supporting Learning Media In Teaching Narrative Writing Text

Digital Resources is supporting learning media that utilize technology in delivering material such as video, website, e-book, and slideshows. This research aims to investigates the implementation of digital resources as supporting learning media in teaching narrative writing text. This research used qualitative method by using descriptive qualitative design. The data was obtained through observation and interview. The subject of this research were two English teachers in Vocational High School Ibnu Khaldun at 10th Grade the academic years of 2022/2023 who implemented digital resources in teaching narrative writing text. The research findings of this research show that the English teachers have used digital resources very well, but it still needs to optimize the implementation of digital resources for the further learnin

Ir(III) complexes of diamine ligands for asymmetric ketone hydrogenation

The use of a combination of IrCl3 with a series of ligands derived from the C2-symmetric diamine diphenylethanediamine (DPEN) forms a catalyst capable of the asymmetric hydrogenation of ketones in up to 85% ee

Synthesis and asymmetric hydrogenation of (3E)-1-benzyl-3-[(2-oxopyridin-1(2H)-yl)methylidene]piperidine-2,6-dione

The synthesis of (3E)-1-benzyl-3-[(2-oxopyridin-1(2H)-yl)methylidene]piperidine-2,6-dione 4 from N-benzylglutarimide was achieved in three steps. The asymmetric hydrogenation of 4 gave either the product of partial reduction (10) or full reduction (13), depending on the catalyst which was employed, in high ee in each case. Attempts at asymmetric transfer hydrogenation (ATH) of 4 resulted in formation of a racemic product

Use of tridentate TsDPEN/pyridine ligands in ruthenium-catalysed asymmetric reduction of ketones

A series of enantiomerically pure tridentate ligands based on the 1,2-diphenylethane-1,2-diamine structure, containing additional pyridine groups, was prepared and tested in asymmetric transfer hydrogenation of ketones using Ru3(CO)12 as a metal source. Alcohols were formed in up to 93% ee in the best cases, and good results were obtained with ortho-haloarylketones

Ruthenacycles and Iridacycles as Catalysts for Asymmetric Transfer Hydrogenation and Racemisation

Ruthenacycles, which are easily prepared in a single step by reaction between enantiopure aromatic amines and [Ru(arene)Cl2]2 in the presence of NaOH and KPF6, are very good asymmetric transfer hydrogenation catalysts. A range of aromatic ketones were reduced using isopropanol in good yields with ee’s up to 98%. Iridacycles, which are prepared in similar fashion from [IrCp*Cl2]2 are excellent catalysts for the racemisation of secondary alcohols and chlorohydrins at room temperature. This allowed the development of a new dynamic kinetic resolution of chlorohydrins to the enantiopure epoxides in up to 90% yield and 98% enantiomeric excess (ee) using a mutant of the enzyme Haloalcohol dehalogenase C and an iridacycle as racemisation catalyst.
