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

The demands to improve the quality of work in a hospital means that ever hospital needs to continually evaluate the existing work performance. 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.

This study aims to learn the effect of learning models on biology learning outcomes in terms of spatial intelligence. This research was conducted at Public High School 4 Kendari, from September to December 2017. This type of research is experimental, with measured variables, namely independent variables consisting of: (1) treatment variables: project-based learning and discovery learning models, and (2) moderator variables: high and low spatial intelligence, while the dependent variables are the learning outcomes in biology. The analysis technique used includes analysis of data descriptive and inferential analysis, done through independent sample t-test. The results of the t-test for Equality of Means test obtained tcount = 3.368, and the sig value was 0.0015 <0.05 at α of 0.05. This shows that the average biology students’ learning outcome, that learned with project-based learning models, is higher when compared with the model of discovery learning in students who have high spatial intelligence. The results of t-test for Equality of Means obtained tcount = -0.858 and sig 0.2015 > 0.05 at α of 0.05. The shows that there is no difference in the average biology learning outcomes of students, taught by project-based learning models compared to discovery learning models, in students who have low spatial intelligence.

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

The aims of this research with respect to Television/TV media literacy are to: ascertain parents’ role in creating an understanding of it; discover the performance of teachers; and determine the problems faced by parents and teachers. This research makes use of the case study method as well as the purposive sampling technique to obtain the required information. Data was collected through in-depth interviews, observation, and literature references, while Miles and Huberman's interactive analysis model was used to examine the data obtained. The results indicate the role of parents in designing an adequate understanding of TV media literacy through verbal and non-verbal communication strategies. The role of teachers is to advise students to watch certain programs, inform them of the schedules of qualified TV shows, give assignments on a variety of things associated with broadcast media and have interactive discussions about the media during classes. Parents are faced with the inability to understand the importance of media literacy owing to their tight working schedules. Similarly, teachers' are faced with lack of time to teach lessons on media literacy in school. Pages 821 to 841

The elaboration of a learning model between a Team Assisted Individualisation learning model and Co-Op  Co-Op learning model aims to improve the students’ understanding of mathematics, which consists of conceptual and procedural understanding with an emphasis on the importance of 4C (critical thinking, creative thinking, collaboration, and communication) skills, and a proficiency in accordance with Education 4.0. A true experimental design was conducted in this study with random cluster sampling techniques for grade X senior high school science students. The analysis of t-independent test resulted that α > p (0.05 > 0.001). It indicated a difference of the students' understanding of mathematics between the experimental class and the control class after the application of the learning model. The average increase in the students' understanding of mathematics on the experimental class was 0.73 (high category), while the average increase in the control class is 0.55 (medium category). These results were confirmed by the preferences of the students’ positive response of 3.23, after the learning process. The elaboration was improving the students' understanding of mathematics through knowledge design, with critical and creative thinking and communication processes through the exchange of ideas in the problem-solving phase so that students have a better and more thorough understanding. Moreover, the elaboration model could be an alternative to a learning model to increase students' understanding of mathematics. Pages 842 to 864

This study aims to examine the effectiveness and practicality of modules used to teach students to think creatively, based on creative problem solving and design thinking models. By adopting a 4D development model, which consists of four stages: define, design, develop, and disseminate, surveys and interviews were conducted at the define process stage which proved that the students who used modules that contain conventional learning models do not help in improving creative thinking skills. The stages of module development have gone through validation tests, and revised, based on suggestions from experts and small group test results. The use of modules shows a significant increase in improving students' creative thinking skills (91.63%) for students in fourth semester in the Primary School Teacher Education study program. The future of this research is expected to be used empirically so that it can investigate the influence of modules related to higher-order thinking skills of students. Pages 904 to 916

In Indonesia, industry has become the biggest contributor for Gross Domestic Product (GDP) which achieved 20.16 % in 2017 according to Indonesia’s Ministry of Industry. As Indonesia’s main economic force, it demands a skilled workforce. One way to generate such a workforce is through Vocational High Schools. However, they have the lowest enrolment rate compared to other education levels according to Statistics Indonesia. According to Indonesia’s Ministry of Education and Culture, one reason for that phenomenon are mismatches of vocational programs with industry in the area. Thus, clustering provinces in Indonesia based on its industrial concentration is necessary. Therefore, data was collected from Indonesia’s Ministry of Industry, including a number of middle to big industries and their workforce. Clustering was carried out based on Fuzzy C-Means, which enables each province to become a member of every cluster and eventually results in eight clusters. The results are used to recommend vocational programs in Indonesia based on industrial concentrations. Pages 917 to 935

Climate change has an impact that is affecting the availability, resilience and sustainability of human life, especially the family and household. The impact of climate change includes floods, extreme climate in the sea, drought, hurricanes, pests and landslides. In these conditions, the resilience of families and households will be affected, due to the complexity of the problems, which are related to the fulfillment of basic needs, lack of clean water, a problem in meeting the needs for food, economic issues, education and family health issues. In this case, most feel a good woman is a wife and family member; who focuses on family. The purpose of this study was to identify the impacts of climate change on women, their unidentified efforts in the face of climate change impacts, which were identified through the efforts of government policies, programs and activities, facing the impact of climate change, especially for women and developing models in the face of women's empowerment impacts of climate change. This research was related to the role of women in the face of climate change impacts in Kupang Regency and sub-districts of Tablolong and Oesao and these locations have been experiencing frequent impacts of climate change such as floods and extreme climate in the sea. The source of the data used was the results of interviews, questionnaires and focus group discussions (30 women participants) with purposively selected informants based on subjects who mastered the problems and so on using snowball sampling. While the use of data analysis was to use a combination of quantitative analysis in the form of cross-tabulation and qualitative analysis. The results achieved by women were instrumental in fighting climate change, and still trying to cope with the impacts of climate change. Similarly, the role of central and local government was limited to the policy level and was not optimal in terms of implementation. This was also found in nine component model implementation PUG.

Department of Mathematics, Faculty of Science and Technology, Airlangga University


Geographically weighted polynomial regression (GWPolR) is a spatial model with varying coefficients and polynomial relationships between response and its predictors. It is a generalisation of geographically weighted regression (GWR) models. By this generalisation, it has more parameters and better goodness of fit measures than the GWR does. Nevertheless, it is important to decide statistically whether the GWPolR model describes a given data set significantly better than a GWR model does. So, to carry out the work this paper aims to derive an ANOVA type test statistic and provide a guideline for performing the test in practice. Then, two simulated data sets were used to evaluate test performance. Those examples have shown that the test procedure has performed well and has provided a feasible way to choose an appropriate model for a given data set. In Human Development Index modelling, the GWPolR model was not significantly better than GWR model. Pages 1106 to 1126

The Ministry of Agriculture in Indonesia stated that there are 11 strategic commodities that have the largest contribution to food security and the formation of inflation rates in Indonesia. There are rice, corn, shallot, garlic, red chili, cayenne pepper, beef, chicken, broiler eggs, sugar, and cooking oil. The supply of strategic commodities that are suitable to the needs of the Indonesian people can maintain the stability of national food security. Indonesia’s Government depends on provinces that become the main producer of most commodities, like East Java. However, a prediction can be made to determine the availability of these commodities in the coming period, based on data from the previous period. Because the data has an oscillation pattern, Fourier series estimators in multi-response case is used to forecast. Fourier series have the flexibility to approach the data pattern smoothly. The data from the East Java Province Government in Indonesia is taken for 11 commodities. The result is an optimal model based on the parsimony model with the small Mean Square Error (MSE), a Generalised Cross Validation (GCV) and the big determination coefficient value. The model that has been selected has a small goodness of fit criteria to forecast. So, Fourier series estimators with a multi-response case is suitable to predict national strategic commodity production in East Java, that give high contributions to Indonesia’s achievement for food security.

The functions, namely regression functions, which describe the relationship of more than one response variable observed at several values of the predictor variables in which there are correlations between responses can be estimated by using both smoothing spline and truncated spline estimators in multi-response non-parametric regression model that is as development of a uni-response non-parametric regression model. In this paper, we discuss estimating regression function of the multi-response non-parametric regression model by using both smoothing spline and truncated spline estimators with application to the association between blood pressures affected by body mass index. Results show that by comparing their mean squared error values, smoothing spline estimators give a better estimate of results than truncated spline estimators. It means that for a prediction need, smoothing spline estimators are better than truncated spline estimators. Pages 1177 to 1199

The basic idea of non-parametric regression is to let the data decide which regression function fits best without imposing any specific form on it. Consequently, non-parametric regression methods are in general more flexible. They can uncover structure in the data that might otherwise be missed. Bi-response non-parametric regression model provides powerful tools for modeling the regression function which represents association between blood pressures and stress score. Spline estimator has powerful and flexible properties for estimating the regression function. In this paper we discuss methods to estimate blood pressure affected by a stress score using least squared spline estimator. The results show that the estimated regression function is linear in observation and biased estimator. Also, we obtain the minimum GCV value of 389.9907, and optimal smoothing parameter values of 0.5255788 and 2.544688. Pages 1200 to 1216
