The rapid growth of home industry, due to population growth, consequently increases the need of wood for construction material. Further, the wood growth tends to decrease. To cope with this problem, a solution is required to substitute the use of limited wood resources. One such solution is to maximize the use of bamboo as construction material. Petung bamboo is one of the types suitable for laminated board due to its thicker stem. In making the laminated board, it is required to have a strong but environmentally friendly adhesive. The use of urea formaldehyde adhesive is harmful for the environment. Thus, it is important to find alternative environmentally friendly adhesive such as those made from sago starch. This type of adhesive is traditionally easy to make. This research studied the use of sago starch as the adhesive in the making of laminated galar board, and compared its adhesiveness with urea formaldehyde. The objective of this study was to identify influence of adhesive variations on the mechanical behavior of laminated galar bamboo that still retains the outer skin. In order to identify the physical and mechanical characteristic of petung bamboo, it is necessary to take a preliminary test based on ISO standards. Laminated galar board specimens were made in two variations: adhesive variation and galar composition variation. Sixteen specimens of laminated galar board were made in various dimensions. For flexural testing, the specimens were made in 16x140x600 mm dimension. For flexural testing of galar board, sample and shear strength testing to the adhesive; the specimens were made to ISO standards. In the making of laminated galar board, urea formaldehyde (UA-125) and sago starch were used as the adhesive. The Compression process was done in two methods: hot and cold compression. Cold compression applied 2 Mpa pressure and hot used 198 Bar pressure. Results of this research showed that variation of adhesive substance and galar composition significantly influenced the values of MOE, MOR and the shear strength to the adhesive. Sago starch adhesive values were still below the values resulted by urea formaldehyde adhesive. The respective values of MOR and MOE, resulted by the two adhesives to the type I board composition, were 104.43 Mpa and 14,139.16; to the type II were 33.34 Mpa and 2.299,45 Mpa; to the type III were 42.67 Mpa and 4,021.77 Mpa and to the type IV were 24, 92 Mpa and 1.777,67 Mpa. Shear strength of gluing line for board type (1), type (ii), and type (iii) were 3.424 Mpa, 0.622 Mpa and 0.762 Mpa, respectively. Pages 492 to 502

One way is to evaluate the patients’ satisfaction with the hospital services. This research aims to describe the covariance correlation among many related variables (multicollinearity), to know the factors that influence the satisfaction of hospitalized patients and to analyse the most dominant factors that influence the satisfaction of hospitalized patients, at the Soe Regional General Hospital.

This research was conducted at the Soe regional general hospital. The data used in this research was primary data through questionnaires, which were answered by 94 respondents as samples; and 1567 as the population, the error tolerance is 10%. The secondary data was obtained from the hospital. In this research, factors analysis was used to reduce seventeen variables, namely information clarity, accuracy of diagnosis, accuracy of drug administration, accuracy of food delivery, food hygiene, work speed, comfortable environment, additional equipment, security standard, hospital equipment security, work competence, hospital staff neatness, architectural design, price, location, image, and communication. Based on the analysis, three new variables were obtained called factors. These three factors are health staff competence, patients’ comfort and the support for patients’ comfort. The result shows that the dominant competency factor of health staff, influenced the hospitalized patients’ comfort. Those factors consisted of accuracy of diagnosis, accuracy of drug administration, standard of feeding accuracy, food hygiene, work speed, image, and communication. This indicates that the work performance in hospitals, especially work competency in Soe regional general hospital, is quite good and it makes patients feel satisfied with the services available.

A teacher is an educational institutions key of success. A teacher is a sales agent of an educational institution. A good or bad behaviour and the way in which teachers teach will greatly affect an educational institutions image. Therefore, teacher resources have to be developed through education, training and other activities, so that their professional abilities are increased. Various efforts have been made to improve the national education quality, such as the development of both national and local curricula, teacher competency improvement through training, procurement of books and learning tools, teacher certification, procurement and improvement of educational facilities and infrastructure and quality of school management. However, it seems that all of these efforts have not shown encouraging results. Every activity must begin with an intention and love for what is done, which is as a foundation for each person. Similarly, learning activities in an education must begin with an intention and a sense of love for the profession of teachering. In this study, the target to be achieved is to comprehend the commitment, discipline, and factors that influence both commitment and discipline, of Islamic religion education teachers, who have certification at Muhammadiyah Junior High School (SMP) and High School (SMA) in Palangkaraya. This study will aim to be useful as a tool for principals to assess teachers’ performance objectively, provide information and make an input for teachers of Islamic religion (PAI) to improve their performances as an effort to increase their professionalism. The results of the study indicate that: 1) Educators currently have to carry out their tasks, in accordance with their duties and responsibilities, by always preparing themselves for the learning process, and always holding the spirit of an educator. 2) There are several disciplines that should be applied by educators to make them become models for their students. The rules made should be carried out “sami’nawaatho’na”; There is punishment/reward when violating/obeying school regulations. 3) Many obstacles exist to enforcing commitment and discipline, sometimes these obstacles come from students and parents.

This paper examines how non-native speakers of Larantuka Malay Variety (henceforth LMV) perceive the prosodic prominences and boundaries of the language, as well as finding out the extent to which the ‘raters’ agree one with another on the values of prosodic prominences and boundaries of LMV. This is descriptive-qualitative research. The data was collected through Rapid Prosody Transcription (RPT) (Cole & Shattuck-Huffnagel, 2016) by involving 16 non-native speakers of LMV who gave their perceptions on every word inside 9 excerpts by scoring the words from 0.0 to 1.0. The data was firstly calculated to find the mean of each word in the excerpts where they are presented in line charts. Secondly, to assess the extent where the raters agree with one another on the perceptions, this is measured by using Cohen’s Kappa Coefficient in statistics software named ‘IBM SPSS Statistics 20’. The results are then classified based on Agreement Categories (Riesberg, Kalbertodt, Baumann, & Himmelmann, 2018). Result shows there is a high variability of inter-raters’ agreement on the prosodic prominences which also means that there is a very small percentage of agreement among the raters on the prosodic prominences. On the other hand, less variability of the inter-raters’ agreement is obtained when perceiving the prosodic boundaries. This means that there is more agreement on the perception of prosodic boundaries rather than the prosodic prominences. Furthermore, it also means that there is a significantly better performance on the prosodic boundaries rather than the prosodic prominences. For a further step, it is interesting to know how native speakers of LMV perceive the prosodic prominences and boundaries of their own language and to compare the results of the native speakers’ perception with that of the non-native speakers.

Playfair ciphers are one of the popular classic encryption methods that are difficult to manipulate manually, but this method has many drawbacks because they only use uppercase or lowercase letters. This makes the combination easier to be guessed, even though it takes time. This study attempts to modify the playfaircryptographic algorithm key matrix with the Key Layer Matrix (KLM) method, by changing the 5x5 key matrix in 2 layers, so that the key combination becomes 25 x 25 consisting of upper and lower case letters. To perfect this modification, the key used is two, the key for layer 1 and the key for layer 2. The results of the calculations, with this method, make the complexity of the process slower, but makes it harder to hack. Pages 602 to 619

Gesture is a key point in nonverbal communication. Gestures can

 help the teacher(s) to convey meaning(s) to the student(s) in the communication process in an EFL classroom. Gestures often occur during teacher’s talks and they have an important role to play in EFL classrooms. This research intends to find out the types of gestures and describe the gestures which were used by the English teachers in an EFL classroom. Thus, the researchers used a descriptive qualitative methodology in the research. This research involved an English teacher who was chosen purposively as the participant. A tape video recording was used to record the teacher’s talk and gestures during an EFL classroom lesson. Then, the researchers screened the pictures from the video to find out the teacher’s gestures. Next, the researchers analyzed and described the types of gestures, which were used by the English teacher. The analyses focused on posture, facial expression, hand gestures and eye contact. The research results showed that a teacher’s gestures can facilitate the teacher and the students’ communication in an EFL classroom. The findings reported that there were 25 hand gestures, 13 gestures of facial expression, 23 gestures of posture and 8 gestures of eye contact. The research indicated that hand gestures were dominate in the EFL classroom. The English teacher seemed to use gestures as a strategy to convey meaning for students in the EFL classroom.

The modified Friedmann equation discussed in this paper is the equation derived by Sheykhi (Sheykhi, 2018) in Tsallis cosmology. Tsallis cosmology is a cosmological model developed by Tsallis and Cirto (Tsallis & Cirto, 2013) based on the thermodynamic entropy of a gravitational system such as a black hole. Syiekhi has provided a solution to the equation for the case of flat universe , but in this paper, we worked on the solutions to the equation for the case of nonflat universe with . We obtained solutions in the form of hypergeometric functions for the era of matter domination and the era of radiation domination, which are only distinguished by constants. For this reason, at the end, we declare the equation solution for both eras in one form of a general solution. In this paper we also provide examples of specific solutions for matter domination era, as an example case, that is derived from the general solution that has been obtained. Pages 638 to 653

This paper presents a mathematical model which conflates two heat exchanger design approaches – the ε-NTU (effectiveness-Number of Transfer Units) and the EGM (entropy generation minimization) – focusing on heat exchangers with uniform wall temperature for determining optimal design of herringbone wavy fin-and-tube condensers used in refrigeration system. Second law analysis on the herringbone wavy fin and tube condenser was conducted on the basis of correlation proposed by Hermes (2013) and the basis of empirical correlations for heat transfer and flow friction characteristics proposed by Wang, et al. (2002), in which the entropy generation   rate was evaluated. An algebraic model which expresses the dimensionless rate of entropy generation as a function of the heat exchanger geometry (number of transfer units), the thermal-hydraulic characteristics (friction factor and Colburn j-factor), and the operating conditions (heat transfer duty, core velocity, surface temperature, and fluid properties) is derived. Results from the mathematical model show that heat transfer with finite temperature difference creates much more effects on entropy generation rate than viscous flow.  Pages 654 to 668

Few studies have identified the type of leadership that could improve a teacher’s self-efficacy. But previous research is silent as to what kind of leadership practices are used to improve teacher’s self-efficacy. To address this gap in the literature, this case study examines how principal leadership practices influence teacher’s self-efficacy, at elementary schools in Bandung, Indonesia. This study will compare the difference between principal leadership practice in a model school and a regular school by using triangulation data as the research method. As a result, there were no significant differences in degree of teacher self-efficacy, between the model school and the regular school. From the qualitative analysis it was found the differences about principal leadership practices by implementation of monitoring in improving teacher’s self-efficacy in model and regular school.

Recently, Indonesia’s cinema is developing and is observed with an increasing audience; from 16,2 million audiences in 2015 to 42,7 million in 2017; according to Indonesia’s Creative Economy Agency. However, that agency also states that Indonesia’s movies earn only 35% of the market share. As such, it is necessary to analyse the cause of Indonesia’s cinema developments and the domination of international movies, in order to boost Indonesia’s cinema performances. Data collection was carried out using questionnaires. Comparative analysis can be done based on Structural Equation Modelling (SEM). The method was preferred for its superiority in modelling unmeasurable variables. Based on the result, factors that determine the competitiveness of the movies include genre, promotion, popularity, personal taste, acting, script, story plot, scene’s shooting, animation, visual effect and music audio. These results could be used as reference in improving the quality of Indonesia’s movies through an educational curriculum. Pages 685 to 707

In Indonesia, tutoring agencies are supporting students in learning outside the school especially close to examinations times. The predictions of the number of students who study in tutoring agencies are important as a recommendation for regulations in the field of education. The number of students who study in a tutoring agency demonstrates a seasonal pattern with an increasing trend, so the Fourier series estimator is used to predict this event. Monthly data on the number of students who enrolled in three tutoring agencies during five years is collected. After obtaining the prediction model based on the best Fourier series estimator for longitudinal data, data exploration is then preceded based on the questionnaire to find out the significant motivation factors from students along with their supporting dimensions related to the reasons for using a tutoring agency. Structural Equation Modelling (SEM) was used to analyse the motivation. The results show that there were three motivation factors for students in joining the tutoring agencies such as reliability, guarantee, and empathy. These results can be used as material for evaluating the education process in Indonesia. Pages 708 to 731
