Abstract
Interlanguage (IL) is termed as a "separate linguistic system based on the observable output which results from a learners attempted production" (Selinker (1972: 35). It situates the learner-system in an intermediate position between the native language and the target language. Second language acquisition (SLA) research has attempted to describe and explain the variation of learners IL. The IL variation based on linguistic context is the most frequently discussed by researchers in SLA field. The term linguistic context refers to either the phonological, morphological or syntactic features which surround the varying element. Some influential studies relating to the IL variation of learner language is illustrated in Ellis (1988), Dickerson (1975), and Young (1991) who investigate linguistic contexts in terms of syntactic variation, phonological variation, and morphological variation respectively. In relation with this study, the variation of nontarget-like English verbs is interesting to analyze especially produced through spontaneous speech by Indonesian learners of English in the university level. Three questions must be answered through this study; (1) do the Indonesian learners of English produce variation of nontarget-like verbs in interlanguage? (2) if they do so, how are the variant types? And (3) how is the suppliance of variant types of nontarget-like verbs performed by the learners into sentencial contexts based on the verb tense system of English?

Abstract
The Sustainable Development Goals (SDGs) is built on the successes of the Millennium Development Goals (MDGs), consists of 17 goals as universal call to action to end poverty, protect the planet, and ensure that all people enjoy peace and prosperity. The assessment of people awareness and knowledge on SDGs is of paramount importance to support any subsequent actions. The awareness of SDGs is higher compared to the previous agenda MDGs only in particular emerging countries hence it requires a better progress after more than three years of its establishment. University students as the agent of changes are supposed to have a higher level of awareness and knowledge rather than average. When the university students have a better awareness and higher knowledge on SDGs, they can actively contribute in supporting, promoting, and achieving the development goals by making use of their academic background. The objective of this research is to assess the level of awareness and knowledge on Sustainable Development Goals (SDGs) among university students in Universitas Muhammadiyah Yogyakarta, Indonesia. Data for this research will be collected by field Survey and Questionnaire. This research will analyze data by using descriptive statistic and Chi-Square. We expect, this research found more than 50% students in UMY have good awareness and high knowledge, which represent UMY students as good agent of changes in the improvement of awareness and knowledge on SDGs in society.

Abstract
Economic development can affect many factors, such as agriculture and industry. These two sectors can significantly affect the economic health. Population growth drives the employment opportunity to be increased. Industry become the area that can provide many employments, extend the industry is not easy because the side effect often take agricultural land area for operation. Industry in Daerah Istimewa Yogyakarta also growing like the other places. The land changing from agricultural land area to other functional land is gradually increasing year by year. This study aim to analyze the correlation between the industrial growth and the decreasing of agricultural land. The data from 2001 to 2016 was analyzed to know the correlation. The results show that there are signicantly correlate between industrial growth and the decreasing of agricultural land in Kulonprogo District, Bantul District, Sleman District and Gunung Kidul District which known as food production center in Daerah Istimewa Yogyakarta. For Yogyakarta City which does not have many agricultural land show no correlation between industry growth and the decreasing of agricultural land area. Therefore growing the industry must consider the land area that be used for expansion.

Abstract
Pineapple leaf fiber/brass/MgO/epoxy hybrid composites has been fabricated and its tensile properties, hardness and wear rate have been investigated. Whilst the fiber is in the form of short fiber (2 mm long), the brass and MgO are particles. The total volume fraction of the fillers was kept constant at 40% with three different ratios, i.e. 5:3:2, 6:2:2 and 7:1:2. The specimens were individually casted using cold press technique. Tensile properties, hardness and wear rate were evaluated in accordance with the ASTM D 638 type IV, ASTM E10 and Ogoshi method, respectively. Their fracture modes were evaluated by closely observed by means of their SEM photomicrographs and optical micrographs, respectively. The results show that the wear rate, hardness and elastic modulus increase with the increase of pineapple leaf fiber content. The highest wear resistance, hardness and elastic modulus were found being 3.728x10-8 mm2/kg, 20.41 BHN, and 407.34 MPa, respectively, at filler content ratio of 5:3:2. Besides, relatively uniform filler distribution and small amount of voids were also noted from the micrographs being obcerved.

Abstract
Malioboro is one of the leading tourist destinations in the city of Yogyakarta. The problem faced is the reduced comfort of tourists because of the limited pedestrian area used for motorized vehicle parking and street vendors. Therefore, the city of Yogyakarta government tried to arrange the Malioboro area by transferring parking locations and structuring street vendors. But in reality, it is not easy for the Yogyakarta city government to do so, because it is related to the economic interests of parking attendants and street vendors. Here government communication finds its relevance, how the government can convey and convince the public about development programs but also can receive aspirations and understand the interests of the community. Based on this background, this study aims to analyze the communication process carried out by the Yogyakarta City government in structuring the Malioboro area. This study uses qualitative methods, with documentation data collection techniques and interviews conducted with the Yogyakarta City Government, Parking Community, Street Vendors Community, and Malioboro visitors. Data analysis techniques use qualitative analysis techniques through the stages of data reduction, data display, and conclusion. This study found two cases of government communication processes in the arrangement of the Malioboro area in 2015-2017. First, a well-run case of government communication was found between the Yogyakarta City government and the Street Vendor Community. Communication runs two ways, feedback from street vendors gets a positive response from the Yogyakarta City government. Receiving and giving good information between the communicant and the communicator made the Malioboro area arrangement program in the street vendor area well done. Secondly, the case of government communications that went badly happened between the government of the City of Yogyakarta and the Parking Guards Community. Feedback provided is not as expected. The communication process was slightly hampered in the relocation of parking from Malioboro to the Abu Bakar Ali Parking Park. The obstacles found in this communication process made the implementation of the policy difficult, even though an agreement was finally reached. The results of the government communication process took UPT became the dominant communicator in the government communication process in structuring the Malioboro area.

Identity Politics of Muslims After Reunion 212 at Presidential Election 2019 Saiman Department of Goverment Science, University of Muhammadiyah Malang Jl.Raya Tlogomas 246, Malang, Indonesia saiman@umm.ac.id Abstract The "212" event in 2016 showed that Muslims basically had extraordinary strength and unity in the socio-political field and this was reinforced by Reunion 212 on December 2, 2018. However, the political system of the power of Muslims was divided into several political parties, oriented and based on Muslims. What is the development and political direction of Muslims in the 2019 Presidential Election on 17 April 2019 later? Does it still show strength and unity? And what factors influence it? This research will be studied using the theory of identity politics and democracy to analyze the orientation, direction, strength and unity of Muslims This study uses qualitative research methods with the technique of collecting data by observation, reference study (documentation) on the phenomena and facts of strength and unity of Muslims. The results show that the political power of Islam is divided into 2 groups, pro to the government or supporting the presidential candidate 01 and supporting the presidential candidate 02 as the opposition of the government. Islamic political power supports 01 on PKB, PPP and PBB, while for supporters 02 on PKS and PAN, and spread to other political parties. So that the political power of Muslims has not become a major force which in majority leads to political support. Factors that influence are the struggle for honesty and truth and the struggle for justice, because every political process in the election must be carried out honestly and fairly according to the election law that the election must be Jurdil (honest and fair).

Abstract
The development of a lightweight structure is being a growing trend in the construction industry all over the world. Ferrocement, a thin-shell concrete reinforced with layers of continuous wire mesh, had seen as an alternative material for this type of construction. However, due to the small thickness and large surface area of the ferrocement, potential of cracks due to drying shrinkage is high. In this study, Polypropylene fibres (PPF) was added to ferrocement mortar as secondary reinforcement. This paper presents the effect of adding PPF to the flexural strength of ferrocement. It was found that under flexural test, 66.6% of the variation in flexural strength of ferrocement was influenced by volume fraction, Vr; 31.4% by percentage of PPF, Pf and 2% by the interaction of Pf and Vr.

Abstract
Mangrove forest produces ecosystem services that benefit human being such as protection from a tsunami, abrasion, carbon sequestration, place for fish nesting, and also for a recreational purpose. However, the values of mangrove forest including recreational value are often ignored. Several mangrove forests have been converted to other uses that commonly produce a more marketed product such as shrimp farm. As a result, loss of mangrove could lead to massive economic losses for the surrounding community once disaster such as tsunami occurs. This study aims to analyze the recreational value of the mangrove forest and estimates the determinant of tourists willingness-to-pay (WTP) for mangrove conservation. A mangrove forest in West Lombok Indonesia was chosen for the case study. Travel cost method was employed to capture the mangrove recreational value. Meanwhile, a logit regression model was run to estimates the determinant of tourist WTP for mangrove conservation. This study found an average recreational value of mangrove forest as much as IDR 109,000 (USD 7.7) per visitor per day. The tourist age, income, and education are significantly influencing their WTP for mangrove forest conservation. This study recommends the related policy maker to improve tourism facilities to attract more visitor to come.

Abstract
The retarding basin decay factor is controlled by retarding or storage factor. Nowadays, the empirical formula of retarding factor is built based on the watershed morphometric. The roles of rainfall and decay coefficient are the important factors for controlling the threshold in predicting the flood. Generally, the analyses are carried out on the soil type parameter, watershed morphometric, and flood. This study intends to investigate the influence of soil parameters on the retarding factor as the new variable to the determination of the decay factor. The result is hoped that retarding basin factor is influenced by the soil texture, effective porosity of the soil, and soil conductivity hydraulic that is as the input for building retarding basin decay factor.

Objectives: To adapt and validate the Nursing Students Professional Behavior Scale (NSPBS) through pilot study to measure professional behavior among Indonesian nursing students. Method: The original instrument (27 items) underwent the guideline of translation and adaptation instrument by World Health Organization (WHO) (2018). The total sample of study is 364 nursing students who ever exposure clinical practice in hospital. The participants were students from Bachelor-level nursing school at private University in Yogyakarta (Indonesia) based on their responses to the Indonesian version from August-September 2018. A Confirmatory Factor Analysis (CFA) using Partial Least Square (PLS)-Structural Equation Modelling (SEM) were conducted to evaluated the validity and reliability. Results: The data had fit for three-factor model including healthcare practice, activity practice and reporting. The face validity and content validity has evaluated by six experts. The CFA showed excellent result with factor loading varying between.70 to .96 for the constructs. While the composite reliability (CR) for all latent constructs range from .90 to .96, which means that the internal consistency reliability was high. Conclusion The translation, cultural adaptation and validation process of the NSPBS Indonesian version are resulted 27 items in three subscales. Indonesian version of NSPBS instrument are valid and reliable so it could implement to measure professional behavior of nursing students.

The study made use of descriptive research design. Both standardized and self-made questionnaire were used to gather data. The study was conducted in Tambacan, Iligan City were Bajao people reside. The study utilized purposive sampling wherein respondents are selected based on the criteria necessary to answer the objectives of the study. The respondent should be at least 12 years old and recognized by the tribe leader as member of the Bajao community. Results revealed that there was no significant relationship between the health status of the respondents and their personal food intakes. 133 of the respondents do not eat the food choices given regardless of their Body Mass Index. Moreover, there was a significant association between their health habits and their health status. It was strengthened by the result that 115 out of 150 respondents said they do not smoke, and 131 out of 150 said that they are not drinking alcoholic beverages. Lastly, there was no significant relationship between their level of knowledge and health status. This was evidenced by the fact that there were 76 out of 150 respondents only knew 1 medicine to cure out of five common diseases, 60 mentioned 2 medicines, and only 14 of the respondents knew 3 medicines out of five common diseases introduced. The study concluded that their nutritional habits cannot be a determining factor for their health status specifically risk for having diet-related health concerns, but health education could still create impact in regards with disease prevention and medical treatment awareness. Creation of significant awareness programs and activities focusing directly to Bajao people of Barangay Tambacan in Iligan City by the Local Government Unit and Non-Government Organizations are highly recommended.

Abstract
Despite the high growth, Islamic banking market share in Indonesia of less than six percent is very small compared to the assets of conventional banks. Given that majority of Indonesia population adheres to Islam, this finding indicates inconsistency in previous researches which found religiosity was the main factor that encouraged customers to patronize Islamic banking services. Many studies have found that there are several factors proposed by customers in banking selection. In addition to religiosity, service quality has a significat influence to the customers decision as well. In this digital era, information technology has changed the financial business model. Digitalization enforces the transformation of financial services to manage the changes in consumer behavior. Furthermore, digitalization has aroused disruption in the financial industry with the emergence of financial technology companies. Using Structural Equation Modelling, this study will examine the relationship between the emergence of fintech companies and the slowdown in the growth of Islamic bank market in Indonesia. This research develops a framework that combines SERVQUAL model, UTAUT2 model and religiosity as factors that drive customers decision in choosing the type of financial service provider. The results of this study are expected to help financial industry players, especially Islamic banks and Islamic fintech companies, to redefine the strategy needed to compete in digital era.

Abstract
The experiment on flow pattern of gas-liquid two-phase flow in 45o inclined capillary channel were carried-out. The research was conducted in 1.6 mm inner diameter glass pipe. The range of gas superficial velocity was 0.025 - 66.3 m/s, while that of liquid was 0.033 - 4.935 m/s. The gas fluid was represented by dry air, while that of liquid was glycerol-aqua solution in various percentage, i.e. 0%, 10%, 20%, and 30% indexed by W, GL10, GL20, and GL30, respectively. The addition of glycerin to the liquid phase was intended to vary the liquid viscosities. The high-speed camera was used to capture the two-phase flow. The captured video images were then analyzed to obtain the flow pattern. As a result, it was found that both gas and liquid superficial velocities affect significantly to the two-phase flow pattern observed. Five flow patterns, namely: plug, bubbly, slug-annular, churn, and annular were observed, while the stratified flow was not obtained. On the other hand, the change of liquid viscosity affects to the shift of the transition line between flow patterns in the flow pattern map

Abstract
One of the main stages to achieve the success of the Online Learning Platform technology is the acceptance of the technology by its users. Therefore, identifying the factors that influence the success of technology acceptance is very important. This study aims to identify the usefulness of technology in the Online Learning Platform. This study uses the Unified Theory of Acceptance and Use of Technology (UTAUT2) approach which has been modified to analyze the factors of acceptance of Online Learning Platform technology. In addition, the Partial Least Square Structural Equation Modeling (PLS-SEM) method was used to test the hypothesis of the research conducted. The expected results of this study are to obtain the most influential factors in the acceptance of the Online Learning Platform technology, to be used later by providers of Online Learning Platform technology as a reference in making strategic decisions for further development.

Abstract
The study aims to examine the effect of corporate social responsibility and firm size on earnings management, and examine the role of corporate governance as a moderating variable in the relationship between corporate social responsibility and company size with earnings management. The variable corporate social responsibility is measured by the amount of CSR costs, and the size of the company is measured by total assets. Corporate governance is measured by the proportion of independent commissioners. The concept of earnings management that adopts the Modified Jones Model developed by Dechow et al. (1995) measured using a discretionary accruals proxy. The study samples are manufacturing company listed on the Indonesia Stock Exchange for the period 2014-2017. The analysis technique uses Moderated Regression Analysis (MRA). The results of the analysis show that corporate social responsibility and company size have a significant positive effect on earnings management. Companies that report corporate social responsibility tend to do earnings management. Corporate governance weakens the relationship between corporate social responsibility and earnings management, which means that companies that are socially responsible, are willing to spend effort and resources to carry out corporate social responsibility activities and strive to meet the ethical expectations of shareholders to the community, which tends to limit practice earnings management so that it will provide more transparent and reliable financial information to investors. Corporate governance weakens the relationship between the size of the company and earnings management. The larger the company as measured by total assets tends to reduce earnings management actions.

Abstract
Rice (Oryza sativa) is one of the main cereals to many people, especially in Asian countries. Rice bran, as one of the byproducts of rice dehulling, has received an increasing attention as a functional foodstuff in recent years. Ferulic Acid (FA) is one of the phenolic compounds found in plant cell walls in both free and covalently bonded forms. It has also been shown that FA has many functions like antioxidant, anti-inflammatory, antimicrobial, antiallergic, anticarcinogenic, antithrombotic, increasing sperm stability, and enzymatic activity. The objective of this study was to extract Ferulic Acid from the phenolic fraction of rice bran oil using ultrasonic method, followed by antioxidant effectiveness analyses. Oil was extracted from rice bran using ultrasonic method in ethanol solvent. The result was analyzed for phenol yields and contents. Variables tested were the concentrations and volumes of ethanol. Antioxidant effectiveness tests were performed on the highest yields of FA. The results showed that the highest yield of 24% was achieved at ethanol concentration of 80%, ethanol volume of 200 ml, and 25 grams of rice bran. Ferulic Acid content in the phenolic fraction of rice bran oil was 10-20% with the highest Antioxidant Effectiveness of 10.71%.

Abstract
Since often encountered the missing prediction of travel mode choice by using the concept of random utility maximization (RUM) for Indonesian context, this study proposed a theory of random regret minimization (RRM) aiming to more precisely predict the chosen travel mode and to increase the model fit. Three variances of RRM were implemented in this study: Classical RRM, µRRM, and PRRM. Meanwhile, Yogyakarta and Palembang were chosen as a case of the study by involving 708 respondents in both cities. A stated preference survey was carried out by offering six scenarios to the respondents. We implement the value of final log-likelihood, rho-square, Akaike and Bayesian Information Criterion, and hit rate to compare the model fit. We also calculate the value of travel time saving, and the elasticity of travel time and travel cost. The result shows that by excluding the rho square, RRM outperforms RUM in both cities. The µRRM produces the best model fit in a case of travel mode choice in Yogyakarta, while there is a tendency that PRRM produces a better model fit than µRRM in Palembang. We also found that RRM tends to generate a higher VTSS, travel time and cost elasticity than RUM. Travellers in both cities also tend to be more sensitive to change in travel time than travel cost.
