Methodology is one of the important elements to implement he objective of education in teaching learning process particularly in English classes. To give the information about two phenomenal methods namely GTM and CLT is the main purpose of this scientific writing since GTM is commonly used previously and CLT is very famous nowadays. In so doing, the strength of this paper is to improve the knowledge of educational practitioners especially in method of teaching English. The comparison between the two methods is elaborated clearly in terms of the principles. The principles are characteristic of teaching learning process, nature of instruction, handling the students' feelings and emotions, the role of native language of students, the language skills that are emphasized, and the way of teacher's response to students' errors. The more beneficial method nowadays is CLT but GTM also still has some positive things offer.
Iron sand as the source of many important minerals is one of natural resources in Southeast Sulawesi. The iron sand minerals that contain TiO 2 has economic value and a number of application i.e. environmental protection, paint industries, sensor and photovoltaic. The extraction of TiO 2 has been done from pseudorutile (Fe 2 Ti 3 O 9 ) using dissolution of HCl 20% and the addition of Fe 0 reductor to optimize the microwave and conventional process. The result showed the optimized yield value of TiO 2 and Fe 2 O 3 are 74.49% and 80.35%, respectively. The power used effect of microwave-assisted to the extraction process was obtained decreasing of 81%, and the extraction time could be efficiency from 6 to 2 hours. The microwave extraction process can increase a yield of TiO 2 and significant decreasing the yield of Fe 2 O 3 in a shorter time if compared to the conventional process.
The coronavirus disease (COVID-19) pandemic in Indonesia has a psychological impact among health workers who are working in hospital and caring for patients with positive COVID-19. This study aimed to examines the psychological impact among health workers in effort to facing the coronavirus pandemic (COVID-19) in Indonesia. Snowball sampling technique was employed to gather the sample in the eight islands. The health workers were responded to the depression anxiety stress scales (DASS-42) questionnaire, with the total of 644 respondents. The results of this study showed that about 65.8% of respondents experienced anxiety due to COVID-19 outbreak, There were 3.3% experienced extremely severe anxiety and 33.1% experienced mild anxiety. Whereas those experienced stress due to COVID-19 outbreak were 55%, extremely severe stress levels were 0.8% and mild stress were 34.5%. Health workers who experienced depression were 23.5%. There were 0.5% with very severe depression and mild depression was 11.2%. There is a closed correlation between anxiety (r=0.152 p=0.000), stress (r=0.086 p=0.029), and depression (r=0.111 p=0.005), to the worried of being alienated if infected coronavirus (COVID-19). The Indonesian government has to handle the anxiety, stress and depression that occurs in health workers in particular and can provide protection to medical personnel so that they do not feel alienated by those around them.
The purpose of the study was to investigate whether or not there is a significant effect of silent short movie on EFL writing achievement of the vocational high school students. This study was quasi-experimental using a nonrandomized control group, pretest-posttest design. There were 61 students who were selected randomly from the 10 classes of tenth-graders of the 6 th State Vocational School in Samarinda. The instruments used in the study was writing test. The result revealed that the vocational high school tenth grade students who were taught by silent short movie (M = 8.01, SD = .32) got significantly different achievement in EFL writing than did the vocational high school tenth grade students who were not taught by silent short, t(58) = -2.22, p = .030. This result suggests that the writing aspects which the students significantly outperformed were text organization, sentence formation, grammar, vocabulary, mechanics, and tidiness.

The research on this transformation process needs further developments. This research aims to produce chitin-based medicinal capsules of mangrove crab shells by microwave methods. The chitin isolation method of mangrove crab shells covers the process of deproteinization, demineralization, and decoloration. The synthesis of chitosan used microwave methods (450 watts of power for 15 minutes) in the solvent of 50% NaOH (w/v) with a ratio of 1:20 (b/v). Chitosan was then hydrolyzed using 20% HCl (v/v) solution to produce glucosamine hydrochloride (GlcN HCl). Preparation of drug capsules with a ratio of GlcN HCl and sucrose solution, namely 3:1, 3:3, and 3:5, respectively. The chitosan yield was obtained as much as 37.5% with a deacetylation degree of 83.8%. The best treatment of the medicinal capsules was obtained on the ratio of GlcN HCl and sucrose solution 3:1.

The results show that chitosan prepared from mangrove crab shell is potentially used as a basic ingredient for medicinal capsules because it met the criteria for Indonesian pharmacopoeial capsules.</span></span></span></span></p><p><span><span><br /></span></span></p>
In order to fulfill the planned change, an organization should seriously take the role of individual perception into consideration, in which the individual plays a pivotal role in the change implementation stage through their act. This study aims to investigate the attitude of readiness to change based on the multidimensional concept, with communication of change and change-efficacy as antecedents. This study involved shariah rural bank, located in East Java, as a research object. Furthermore, a quantitative approach was employed in this study, in which survey as a procedure for collecting data through questionnaires. In addition, PLS-SEM was employed as an analysis of research method. The results exhibit that communication of change contribute to develop of almost all forms attitude of readiness to change and change-efficacy can predict all forms of readiness to change. Finally, this study offers several implications, both theoretically and practically.
This study aims to obtain phenolic lignin derived compounds through the lignin degradation of oil palm empty fruit bunches (OPEFB) using TiO 2 photocatalyst and its antifungal activity against Fusarium oxysporum. The lignin degradation of OPEFB begins with the extraction and isolation stage using the soxhletation method with the presence of sodium hydroxide as a catalyst. The success of this stage is indicated by Gas Chromatography (GC) measurement of 4-vinylguaiacol and Fourier Transform Infra Red (FTIR) spectroscopy measurement that indicated the appearance of seven specific peak of lignin occurring at wave numbers 3421 cm -1 , 2929 cm -1 , 1596 cm -1 , 1508 cm -1 , 1462 cm -1 , 1041 cm -1 , and 875 cm -1 . This result is supported by the appearance of specific peaks of guaiacyl and syringyl groups at wave numbers 1328 cm -1 and 1220 cm -1 . Based on the variation of the degradation time, the lignin degradation of OPEFB with a degradation time of 15 min. showed optimum results in the production of lignin derived compounds. In addition, it also provides a strong inhibitory response to the growth of Fusarium oxysporum with a clear zone diameter 2.39 cm.
