Abstract
This study aims at identifying the existing condition of traditional markets after revitalization in Semarang Municipality, analyzing the government policies and analyzing social capital as an effort of maintaining the existence of traditional markets. This research was conducted in 2018, and the data were collected using the FGD and questionnaire. The data is analyzed using the mix method. The market existence indicators have 3 criteria, namely analysis of traditional market existence, analysis of government policies related to traditional markets, and analysis of social capital. The research results indicate that Sampangan, Rasamala and Peterongan Markets have stagnant existence direction. This means the existence of these markets is stable with neither acceleration nor declaration. Meanwhile, Bulu Market is inclined towards a declining trend. The market facility and infrastructure indicator shows that while the infrastructure is better and more modern, the number of buyers decreases and, hence, sellers income decreases. The human resources of the market administrator factor need to be improved by providing them training on healthy market management. Finally, social capital constitutes the key to the traditional market to survive in which such a matter is not found in the modern market.

Abstract
The main objective of this research is to provide an analysis of working capital management from selected manufacturing firms in Indonesia and Thailand. The research include an empirical analysis to examine if more efficient working capital management improves firm accounting profitability and firm value. The secondary data was derived from Indonesia Stock Exchange and Thailand Stock Exchange. Database of 218 companies is selected for the ten-year period from 2008-2017. Cash conversion cycle is the measuring tools to calculate the efficiency of working capital management. There are two performance measurement in this study, Tobin-s Q used for examined market valuation and Return On Asset used as represent profitability on manufacturing firms. Leverage, firm size, firm age, growth opportunities and economic conditions are taken as control variables. The study used panel data and regression analysis to test the hypothesis. The results shows that there is a significant negative relationship between working capital management and firms- profitability as well as a significant negative relationship between working capital management and firms- value in Thailand. Meanwhile in Indonesia, working capital management has proven to have no significant relationship with firms- value but has a significant negative relationship with firms- profitability.

Abstract
This research examines the relationship between corporate governance mechanisms such as board size, board independence, female directorship, ownership concentration, directors ownership and audit reputation on firm performance and examines the effect of financial leverage in mediating corporate governance and firm performance. This research was conducted on 113 manufacturing companies listed on the Indonesia Stock Exchange during 2013-2017 with a total of 565 observations. Panel data regression using the STATA 15.0 program is done to test the hypothesis. We find that board size has a positive effect on firm performance, while female directorship and ownership concentration have a negative effect on firm performance. Financial leverage partially mediates the effect of board size and ownership concentration on firm performance. This study contributes to corporate governance literature, especially factors that can mediate the relationship between corporate governance and firm performance.

Abstract
The negative effects of entrepreneurial activities on environment should not be disregarded. Sustainable entrepreneurship has been recognized as a strategy in rectifying environmental issues through entrepreneurial activities. However, developing sustainable entrepreneurs is still in its infancy stage in Malaysia. Most of the Malaysia small and medium enterprises (SMEs) still regard it as a new practice and not many of them have actually embarked on it. As such, this study investigated the formation process of intention towards sustainable entrepreneurship through individual orientation and perception. This study surveyed 404 SMEs owner-managers in Malaysia through self-administered questionnaires. The results indicated that the two components of individual orientation (i.e.: time orientation and sustainability orientation) were positively and significantly related to intention towards sustainable entrepreneurship. Meanwhile, the results also showed a significant partially mediating role of perception between individual orientation and intention towards sustainable entrepreneurship. This study contributed to the literature by confirming that the formation process of intention towards sustainable entrepreneurship was successfully influenced by two important determinants, namely individual orientation and perception. Practically, it highlighted some crucial factors in promoting sustainable entrepreneurship among SMEs in Malaysia.

Abstract
The purpose of this study was to determine the same leading sector based on the Klassen Typology method, Location Quotient, Shift-Share, Growth Ratio Models and Overlay. This research is based on the fact that all this time previous research only determined the leading sectors based on each of these criteria and none of them determined which sectors were the same. It is important to know that these superior sectors are tested from several methods and these sectors must be prioritized in development. The data in this study uses the average GRDP Blitar City data on the basis of constant prices in 2010 according to business fields from 2011-2017. The results of this study conclude that the same leading sector based on these 5 methods in Blitar City is 1) Large and Retail Trade; Car and Motorcycle Repair, 2) Information and Communication, and 3) Financial and Insurance Services. Therefore, the Blitar City government must continue to move these sectors forward by increasing investment and ease of licensing so that the sector can continue to increase its contribution to the economy of Blitar City.

Abstract
Islamic mutual funds emerged in Indonesia in 1997 and became a favourite investment instrument for investors. Islamic mutual funds have a rapid growth in TNA of 285.40% from 2013 to 2018 which is superior to conventional mutual funds with a growth of only 157.17% in the same period. Islamic mutual funds are also growing rapidly in countries with Muslim populations and countries that have advanced Islamic financial systems, also able to outperform conventional mutual funds and its benchmarks. In the Indonesian market, despite the majority of populations are Muslim, Islamic mutual funds do not have a better performance than conventional mutual funds. This study also discusses the associations between the fund-flow and the performance of conventional and Islamic stocks and mixed funds. Evidence suggests that in the Indonesian market, the fund-flow and performance are negative and convex positive.

Abstract
Businesses in today-s world are starting to use social media to convey marketing messages. There is an ongoing trend among businesses to use casual language and post light, humorous content in social media, in order to reach and connect with their consumers better. This research would examine the influence of different types of a brand-s social media content towards awareness. The objects of this research are social media profiles of two different brands. A total of 420 respondents are split into two equal groups. The first group is given a profile that applies a more informal content and the second group is given a more formal content. Data is processed using Structural Equation Modeling method. Results show that there is an important variable that precedes awareness, which is brand credibility. Besides, a significant effect towards awareness is shown in the group that receives formal social media content, but less on the group with informal content. The results of this study shows that shaping brand awareness through social media should be done through shaping the consumers- perception that the brand is credible and trustworthy.

Abstract
This study aims to evaluate Fraud Risk Management at the Directorate General of Taxes. more detailed, in evaluating the business process of auditing and supervising Taxpayers by tax auditors and AR. This study combines two concepts of fraud risk management, namely fraud risk management from COSO and CGMA. Other literature used is a risk management policy that has been implemented in the Ministry of Finance of the Republic of Indonesia. The research method used by the author is a qualitative method, where the data obtained comes from the reports contained in the Directorate General of Taxes and direct observations and interviews which are then analyzed by qualitative methods. From the field data obtained, it is known that the Directorate General of Taxes is still not optimal in conducting fraud risk management. This can be seen from the absence of a standard mechanism in managing fraud risk. The results of the study are expected to provide input in the development of fraud risk management so that fraud actions can be minimized and prevented.

Abstract
Despite the increased growth of e-commerce in Indonesia, the adoption rate of mobile banking is quite modest. Past studies on intention to adopt mobile banking tend to focus on only one bank provider. To fill this research gap, the purpose of this study is to examine Indonesians- intention to adopt mobile banking by using theories of planned behavior (TPB) across four major bank providers. The methodology of the research was quantitative and data was collected through an online questionnaire of 403 Indonesians. Multiple regression method was implemented to analyze data. Findings of this study showed that attitude and perceived behavioral control significantly influence Indonesians- intention to adopt mobile banking whilst subjective norm did not significantly influence their intention to adopt mobile banking. The outcomes of this study would be beneficial for bank management to conceive strategies and policies regarding mobile banking in Indonesia.

Abstract
There have been purposeful researches in synergistic combination of organic and inorganic materials as antibacterial agent which aims to combine two or more antibacterial compounds in a carrier system. This research aimed to study the physicochemical properties of silver loaded kaolinite attached with different amount of cationic surfactant hexadecyltrimethyl ammonium (HDTMA) and its effect on Gram positive and Gram negative bacteria. Kaolinite was initially modified with silver ion and later, with different concentrations of HDTMA (50, 75, and 100% of CEC of the kaolinite). The samples were characterized using X-ray diffraction, Fourier transform infrared spectroscopy and field emission scanning electron microscope equipped with energy dispersive X-ray analyser. Antibacterial activity was evaluated using disc diffusion technique against Escherichia coli and Staphylococcus aureus. Characterization results showed that kaolinite was successfully modified with silver ion and HDTMA. For antibacterial assay, S. aureus was more susceptible than E. coli due to differences in their peptidoglycan structure. Surfactant-modified silver kaolinite was more effective in inhibiting bacterial growth than silver kaolinite with inhibition diameters of 2.3 cm and 1.7 cm, respectively. However, the different concentrations of HDTMA did not contribute to the inhibitory effects against the bacteria. Thus, the low concentration of HDTMA loaded on silver-kaolinite is suitable to be used as antibacterial agent.

Abstract
The import of soybean is still a necessity for the Indonesian government to meet the gap between domestic demand and supply. This paper aims to analyze the trends of soybean import and its contributing factors in Indonesia. The study employs a descriptive analysis by using secondary data in the form of time series from 2003-2017. Data analysis uses trends analysis and single equation model with Ordinary Least Square method. The main finding shows the trends of soybean production are to follow a quadratic pattern, tends to decrease with an average 6.12% per year, while demand and import linearly tend to increase respectively with an average 3.30% and 3.03% per year in 2018-2022. The projection of the production will increase 27,60% in 2018 from the previous year and will gradually continue to decline to 0.4 million tons in 2022. Meanwhile, domestic demand projects 3,3 million tons in 2018 will increase to 3.7 million tons, and import volume is 2.5 million tons in 2018 and will increase to 3.0 million tons by 2022. The main factors contributing to the import partially are domestic production and demands and follow by the exchange rate, the national and international prices of soybeans. Statistically shows the increasing every ton of production will affect to decrease 1,02 tons of import volume, and the increasing every ton of demand will increase 0.99 tons of import volume. Thus, the import policy is still unable to stimulate domestic production to fulfill the increasing domestic demand.

Abstract
This study aimed to determine the value of effective moisture diffusivity, and the activation energy of red pepper in a conventional forced convective drying based on electricity (Conventional convective drying/CCD) and forced convective drying based solar energy (Convective Solar drying/CSD). The value of effective moisture diffusivity was determined using equation, which refers to Ficks 2 law. The value of the activation energy is determined by the Arrhenius equation as a model of the relationship of inverse temperature and the value of (Ln) effective moisture diffusivity. The results showed that the values of effective moisture diffusivity of CCD 70 C were higher than the effective moisture diffusivity of other drying systems. The result of regression analysis between the drying layers (X) and effective moisture diffusivity (Y) showed a polynomial pattern with R2 value : 0.85 (CCD 70° C): 0.81 (CCD 60° C); 0.88 (CCD 50° C) and 0.48 (CSD). Coefficient determination (R2) values, which were relatively high in CCD, indicated that the drying systems are more stable than CSD, which is depended on the environmental conditions. The result of the drying activation energy calculation showed that the value of CCD-s activation energy was 36.36 KJ/mol K, while the value of CSD-s activation energy was 31.28 KJ/mol K. Those results were consistent with the results of the previous studies.

Abstract
Hospital waste has a huge impact on the organism around its disposal even though it has been treated using the right wastewater treatment plant (WWTP). Various obstacles regarding WWTP are waste water quality standards that are not in accordance with the standards of environmental laws, thus requiring more efficient and environmentally friendly innovations, namely using bioremidiation of indigen bacteria. Indigenic bacteria are obtained from hospital waste from Darsono, Pacitan Regency. The purpose of this study was to detect an increase in biological indicators (BOD, COD and TSS) in the bioremediation process of hospital waste after being treated with indigen bacteria originating from the waste of RSUD Dr. Darsono, Kab. Pacitan is a bacterial species that has the potential as a bioremidiation candidate: Acinetobacter baumannii, Enterobacter agglomerans, Aeromonas hydrophila, and Burkholderia cepacia. This research is an explorative descriptive study. The results showed that the variant Enterobacter agglomerans had the highest starch hydrolysis, the variant Aeromonas hydrophila had the highest hydrolysis of the protein, and the Burkholderia cepacia variant had the highest fat hydrolysis. The biggest decrease for four days was produced by the Pabc outlet, this was due to a combination of three bacterial isolates that were able to hydrolyze starch, protein and fat from hospital waste. Likewise, with the results obtained by TSS. Decreasing levels of BOD, COD and TSS will improve the condition of the aquatic environment. thus dissolved oxygen (DO) levels increase. this is in accordance with the research conducted that there was a relatively high TSS decline until the lag phase. On the fourth day the treatment showed that TSS had experienced a relatively significant decrease below the quality standard threshold of 100 mg / l contained in the Decree of the Minister of Environment No. 58 of 1995. The greatest reduction is in the outlet k-without treatment this is due to the presence of indigenic bacteria that have not been isolated.

Abstract
East Nusa Tenggara is Indonesias fifth largest producer of beef, but household consumption of protein is less than the national protein sufficiency rate. This study analyzed the impact of changes in income, price, residence status, and demographic factors on demand for animal food using the Quadratic Almost Ideal Demand System approach with Poi procedure. There are 5,742 data of households in East Nusa Tenggara based on SUSENAS in March 2016 which was analyzed. The results showed that eggs were normal goods, while chicken, beef, fish, and milk were luxury goods with the highest income elasticity were chicken, beef, milk, fish, and eggs respectively at 1.8611%, 1.8321%, 1.4634 %, 1.2407%, and 0.4351%. Chicken is the most elastic commodity, followed by beef, fish, and milk, while eggs are inelastic because of the value of its Marshallian own-price elasticity less than 1. The increase in chicken prices, followed by an increase in income, increased the egg demand by 9.75%. The increase of beef prices and income simultaneously, increased demand for milk by 7.35%. The chicken had more substitutes available, so the chicken was the most elastic demand. The stability of chicken prices is important to increase animal food consumption in East Nusa Tenggara so that the number of protein sufficiency could be immediately fulfilled.

Abstract
The presence of religious symbols in the narrative and campaign for the 2019 general election in Indonesia concludes that religion can be a political tool for directing political choices. Religion and symbols are used as vehicles and a way to mobilize the masses to get the votes of voters. As a result, Indonesians are permissive to the phenomenon and are involved in the polarization of identity politics. Democracy, which should be the stage for fighting for ideas, turns into religious legitimacy against political interests. From the private sphere, religion turns into a political strategy in the public sphere. This article discusses and conducts a descriptive analysis of the use of religious narratives and symbols by Indonesian political actors seen from four approaches, namely religiosity, ritual expression, Religion and Public Role and Politics of Identity and Pop Culture. The findings through descriptive literature analysis show that the use of religious symbols is not related to the religious attitude of the Indonesian people and is not part of religious rituals. This attitude arises as an effort to build and carry out identity politics, to gain political interests and not for the interests of religion and religious people.

Abstract
Abstract There is a very interesting relationship between political development and political parties, namely that both emerge as a response to the independence of the country. Malaysia and Indonesia are two countries that provide examples of how political development relations and political parties have a strong influence. Political development hopes to grow in a democratic space. But in reality, the political development in Malaysia and Indonesia at the beginning of these newly independent countries was in fact not like that especially because it was related to the existence of Islamic parties. The focus of this paper is how the development of Islamic party politics in Malaysia and Indonesia grows and develops? What is the response of the Malaysian and Indonesian governments to the emergence of the Islamic party? Is the democratic space given to the authorities by the Islamic parties? In answering the issue, the research method used is through the historical approach of archival and publishing documents. The results of the research conducted found that the political development of Islamic parties in Malaysia and Indonesia at the beginning of the establishment of the country received a negative response from the government. For reasons of development the government considers the party a barrier to development. The implication is that there is an attempt to break the Islamic party and make them enemies. So that the democratic process that should have grown in political development in Malaysia and Indonesia at the beginning of the two countries did not run fair.

Abstract
This study aims to identify the learning obstacle of students on the basic concept of derivatives. The research used descriptive qualitative. Data of the research was obtained from the results of tests and interviews given to six participants as the pre-service mathematics teachers from two different institutions in West Java. The test is given consists of seven questions related to basic concept of the derivative. Then the answers to the questions were confirmed again by clinical interviews. These data are then analyzed by the framework of APOS theory (Action-Process-Object-Schema) with the aim to overview the thinking of processes who experienced by participants in answering the questions given. The results of the study show that there is still some learning obstacles experienced by partisipants in understanding the basic concepts of derivatives. Constraints experienced include the lack of mathematical connection skills regarding the basic concept of derivatives, the operation of a function that is still wrong, and the lack of a meaningful process for the concepts learned so that problem-solving processes are still limited to procedural problems. Based on this research, it is recommended that pre-service mathematics teachers can internalize derivative concepts learned so that the knowledge scheme formed can be better.

Abstract
This article presents a comparative political model of Islamic societies in Indonesia and Malaysia. The political model of Islamic development was primarily determined by the ideology and the leader-s thought and strategies, although the strategy is often meant as the preaching efforts. In Indonesia, the preaching of Muhammadiyah is different with Al-Washliyah. Muhammadiyah is the Islamic society that struggling the religion purification and modern thoughts without depending to the Maddhab, while the Al-Washliyah keeps using the Maddhab as the ideological thoughts. The both Islamic societies use a holistic preaching strategy and keep their political distance against the government. This is on contrary with the Pertubuhan Kebajikan Islam Malaysia (Perkim), an Islamic society that has significant role in Islamic development and preaching activity in Malaysia. There is no political distance between the Perkim and government. In fact, most of the Perlim leaders are part of the government. Those difference in phenomena are interesting to analyze especially the difference in ideology and developmental politics through Forum Group Discussion (FGD) approach. The findings showed that the difference of political orientation and leader-s thought were the main factors of the difference of developmental politics in regard with the political distance against the government which was a part of strategic development. Differently, the absence of political distance between Perkim and the government indicates their poor political involvement, because it is merely focused on the Islamization efforts.

Abstract
Collaborative skills are the ability to cooperate, share tasks, and discuss by exchanging knowledge to solve problems. The research purposes is to identify collaborative skills using sharing and jumping task for acid-base topics. The research method is descriptive with research subjects students of class XI MIPA 4 in one of the high schools in the Bandung. The instrument uses observation sheet of the seven collaborative skills indicators and recording of learning transcripts analyzed using Transcript Based Lesson Analysis (TBLA). The result is the first sharing task, the first collaborative indicator, that is asking friends / teachers when student do not understand, is the most frequently identified indicator, while the seventh indicator that uses problem solving skills for goal resolution is the least identified indicator. The second sharing task, the first collaborative indicator, that is asking friends / teachers when student do not understand, is the most frequently identified indicator, while the fourth indicator, which is collaborating or sharing assignments to complete tasks, is the least identified indicator. In jumping task there are two student "jumping" who experience changes in attitudes during the learning process. The conclusions is sharing and jumping task learning can develop collaborative skills.
