Abstract
Overall Equipment Effectiveness (OEE) is provided a formula that is used to measure productivity and diagnose system deficiencies in equipment. In traditional usage, these matrix formulas have the disadvantage of detecting the internal milk-run method in its application. Where the flow of goods / products flows to the manufacturer uses material handling to supply the manufacturing area, to overcome the vulnerability, Overall Transportation Comparison Development (OTE tr) and the Overall Throughput effectiveness (OTE tr) The goal is twofold: measuring the productivity in manufacturing ratios seen from the product flow during entering the factory (Tr) and when it exits from the production process (Th), and can also be carried out diagnostic internal milk-run on the production area. This journal describes the OTE development methodology, which increases productivity with continuous production of products and engine capacity in manufacturing. which is the combination combinations product (> 2) and more supply in raw material supply in the production line. in general, the OTE tr is only used by Material handling outside of manufacture, matric transportation in this case will be adjusted in material handling equipment concept. OTE Implementation in the study case: Industry automotive can be identified as a whole.

Abstract
This study is intended to determine the effect of the literacy level of Islamic cooperative members on the financial performance of these institutions. It analyzes 14 Sharia cooperatives in the Special Region of Yogyakarta as samples, which were selected using the purposive sampling method. The measurement of cooperative literacy uses 6 indicators, which is measured the knowledge of institutional identity (JDL), the duties and obligations of institutions (TDK), the organizational institutions (KL), the role of cooperative members (PA), the deposits mechanisms (MS), as well as the financing mechanisms (MP). Financial performance is measured using net income, total assets, total deposits, solvability, liquidity, and profitability. The results show that all cooperative literacy indicators have a significant influence on the level of cooperative literacy. Meanwhile, the cooperative literacy of members does not have a significant positive effect on the financial performance of the institutions. It tends to be due to the lack of cooperative education for its members so that they do not have enough knowledge about all aspects of their cooperatives.

Abstract
Strawberris local varieties generally have advantages that fragrant of fruit but low production because the small size of the fruit. Farmers have been left to their local varietis, because introduced vareities have advantages in high production and larger fruit size but has a fruity aromatic content that is less than the local variety. For fresh consumption, strawberries are also cultivated for industrial purposes. Each variety has the characteristics and the characteristics of each, both in flower or fruit (size and weight of the fruit). The aim of the exploration is to enrich the genetic diversity of existing germplasm, hopping netted new alleles or mutant derived from emerging from the cultivar released to farmers. The emergence of new genotypes as as result of the evaluation process, mutation, natural hybridization, and natural selection lead to the emergence of new genotypes that are superior in the sense adaptable to the environment. Futhermore, the introduction of identification as a process plant to determine the yield of four varieties of genotypes strawberries found in Ciwidey to obtain genes as a source of elders to get superior varieties

Abstract
The startup business in Indonesia continues to grow, one of which is now rapidly advancing is a new industry of financial technology or commonly called Fintech. Reporting from Wikipedia, Fintech is a new technology and innovation with the aim of competing with traditional financial services and facilitating public access to these services. Fintech aims to make it easier for people to access financial products, facilitate transactions and also improve financial literacy. In Indonesia, Fintech companies are dominated by startup companies with great potential that develop in various sectors, starting from payment startups, lending, financial planning (personal finance), retail investment, crowdfunding, remittances, financial research , and others. In September 2015 the Association of Fintech Indonesia (AFI) was established which aims to provide a reliable and reliable business partner to build the Fintech ecosystem in Indonesia. Globally, the Fintech industry also continues to grow rapidly, as evidenced by the emergence of startup companies in this field and Fintech users also continue to grow significantly, from around 7% in 2007 to 78% in 2017. Based on statistical data, the total value of Fintech transactions reaches US $ 18.65 billion (Rp. 252 trillion) or grew 24.6% from the previous year. The number of users recorded per 2017 is 135-140 companies. As a result of the predicted development of Fintech, Bank Indonesia as the payment system authority holder is shown by the formation of the Fintech Office in 2016 which made regulations to regulate the running of this new sector safely and comfortably. Jagtiani and Lemieux (2016) found that technology has enabled lending, increased the ability of large banks to provide small dollar loans to consumers and business. The other result found an increase in bank lending in areas where larger banks do not have a physical presence. Research motivation in this paper, we will investigate the advantages and disadvantages of consumer loans made by a large fintech lender and similar loans that were originated through traditional banking channels in Indonesia.

Abstract
A new energy dissipation device that combined the BRB and pipe damper systems to form the buckling restrained slit pipe dampers (BRSPD) is proposed. This device incorporates a slit pipe damper that is limited by the inner tube. The outer tube was used as a restraining mechanism. Slit in the pipe is used to control energy dissipation and deformation capacity. This damper is designed to provide adequate hysteretic performance through core yielding under both tension and compression. A series of cyclic loading tests were conducted on the BRSPD and component test with the proposed devices. It was found that the BRSPD sustained significant strength and energy dissipation capability before reaching 3% drift ratio, if adequate number of slits in the core pipe was used.

Abstract
Sutami Dam has the largest reservoir In East Java. This reservoir has been operating for more than 46 years (operating in 1972 and the latest data as a reference in 2018). Data Aspect for analysis then calibrate with data in 1972 for comparison and to see the trend of sediment for 46-year operation. To find out the sediment carrier area, the review point is selected. The review point as a source of sediment in the Sutami Reservoir is divided into two sediment points with direct inflow to the Sutami Reservoir (Metro River) and the Sengguruh Reservoir outflow (Brantas River and Lesti River) and compare with Erosion from the field. These three points were calculated by sediment discharge to determine the most influential sediment carrier points in the Sutami Dam. The greatest Sediment carrier is from the Sengguruh Dam outflow (Brantas River) with Qs = 2.34 kg/s (2018), then from the Metro River with Qs = 2.27 kg /s (2018).

Abstract
This research aimed to investigate the best culture strategy of Sambas Orange. The fruit was the icon of Kabupaten Sambas. The damaged Sambas orange plants were caused by some factors such as its trade system. There are many farmers who are growing the orange. They are expecting that the fruit become the icon of the place so that it can increase their welfare. This research was conducted in 2018 in Kecamatan Tebas, Kabupaten Sambas, the center of Siam orange plantation. The sampling was through two stages. The first stage was determining the sample of village through purposive sampling; Segarau Parit was chosen for its large area and high production number. The second stage was determining the sample of farmers through random sampling. SWOT analysis was implemented. The result of research revealed that the required strategy was aggressive Growth-Oriented Strategy or SO that is optimizing the field usage and seasonal arrangement. The proposed actions involved: 1) mapping field that is appropriate for orange plantation, 2) using the field for only growing orange, 3) improving post-harvest for fresh fruit to deliver, and 4) improving the trade system for equal benefits.

Abstract
The institutional development of the Soloraya Tourism Forum is one of the governments efforts to develop tourism in Soloraya in a synergic, integrated and sustainable manner. This study seeks to discuss the perspective of institutional theory related to aspects of network analysis at the empirical level to analyze whether the formation of a soloraya tourism forum is able to strengthen the network or even sharpen competition among stakeholders. Many institutions emphasize the rules of the game and collective activities for common or public interests, for this reason this paper focuses on the structure, functions and management of forums to find answers to research questions. The method in this study uses document analysis, literature study and direct observation. The results of the study indicate that the institutional development of the Soloraya tourism forum sharpens competition for interest. Stakeholders perceptions vary mainly in relation to the implementation of regional autonomy. They tend to stay away from the integrity that can be identified from the policies of each region, so as not to support the success of the Soloraya Tourism Forum. We also describe interactions between stakeholders that are not related to each other.

Abstract
Dhikrullah, in the Koran mentioned as one of the main commands to Muslims, but the study of mentioning the name of Allah scientifically in order to find out what phenomena occur in humans when doing dhikrullah until now has not been maximized. This study is an academic response to the phenomenon of dhikrullah which has emerged frequently among Muslims lately. This study used qualitative data from 4 informants to find the dhikrullah model and quantitative data from 10 subjects were obtained through Electro Encephalo Graf to see the effects of dhikrullah on brain waves. The results show that there is a relationship between the scalp hygiane with brain waves. Special room dim light affect brain waves. Tense skin affects brain waves. Doing hyperventilation as in dhikrullah helps to detect disturbances in the brain. Closing eyes during dhikrullah produce alpha waves in the brain. Dhikrullah by moving the tongue can be recorded by using EEG. Therefore, the authors conclude that this study is a new approach to see the phenomenon of dhikrullah. The United Nations, especially WHO can use the phenomenon of dhikrullah as a new approach to help people who need a solution from a permanent spiritual approach.

Abstract
Catur is a village located in Bangli in the central mountains of Bali, which recently initiated Community-Based Tourism (CBT) project. The main attractions for Catur tourism village include a unique blend of nature and culture, along with the production of single-origin Arabica coffee as a part of the Kintamani geographic indicator branding. Since the CBT project is only in its early years, Catur village is currently still lacking in the amenities and ancillary services to support tourism. However, the local tourism council expressed the desire to start offering tourism packages that are suitable for the village given its current situation. Based on extensive qualitative research, this study was able to recommend the development of educational tourism that revolves around nature trekking, single origin coffee, and unique cultural blend available in Catur. This topic is of particular interest due to the rise of the third-wave coffee movement, in which an increasing number of Millennials and Generation Zs are becoming increasingly more interested in where their coffee comes from and how the coffee is produced. The authors then assisted the committee in charge of developing tourism packages in designing half-day and full-day excursion packages for tourists interested in learning while exploring nature, in improving the presentations of the single origin Arabica coffee from Catur, as well as in training the would-be local tour guides on the techniques of tour-guiding.

Abstract
Chickpea (Cicer arietinum L.) is the first rank among cool season legumes on the basis sowing area, and the crop is mostly grown in marginal areas under rainfed conditions in the world. Therefore, chickpea is exposed to high temperature and drought stresses. Extreme temperature in the near future has been predicted to increase due to climate change that caused to take place high temperature and drought stresses. Therefore, it is necessary to release cultivars to be resistant to high temperature and drought stresses to maintain stable production of chickpea. C. judaicum, C. bijugum, C. pinnatifidum and C. reticulatum have been shown to be tolerant to drought stress. Perennial wild Cicer species including C. anatolicum, C. microphyllum, C. montbretti, C. oxydon and C. songaricum were found to be tolerant drought. Wild Cicer species are considered to be superior to drought and heat stresses. Although perennial wild Cicer species have been shown to be significantly tolerant to drought stress, only two Cicer species can be crossed with the cultivated chickpea. To overcome these stresses, all Cicer species should be used in a long-term breeding program to produce chickpea cultivars that are tolerant to high temperature and drought stresses.

Abstract
Islamic banking in Indonesia has been growing rapidly since 2010. Based on the profitability, the Return of Asset (ROA) of Islamic banking during the 2011-2018 period was 1.47%. Based on the ROA, Islamic banking is classified as the healthy bank. The level of profit of Islamic banking, however, depends on the internal and external factors. The internal factors of the bank are such as from the financing ability, efficiency and non performing financing. While the external factors depend on macroeconomic conditions such as inflation and exchange rates. As a country with an open economy, macroeconomic conditions are very volatile. Through the theory of exchange rate pass through, exchange rate fluctuations affects domestic prices so that it affects the profits of Islamic banking. This study analyzes the impact of volatility of the macroeconomic variables, namely the exchange rate and inflation on the profitability of Islamic banking. The Exchange rate and inflation instability are measured using the GARCH (Generalized Autoregressive Conditional Heteroskedasticity). The study applied ARDL (Autoregressive Distributed Lag Model). The data used is monthly data starting from January 2011 to June 2018. The results of the study show that the exchange rate and inflation instability depress the profitability of Islamic banking.

Abstract
Road damage occurred in Bantul Regency today is a very complex problem and it has led to the very significant losses particularly for the road users such as the long travel time, discomfort and even accident. Some factors of road damage might be related to the traffic load, puddle due to the poor drainage system, material, dynamic climate, implementation, and poor sub grade condition. This research aims to assess the road surface using the Pavement Condition Index (PCI) method by conducting a visual survey in field. PCI refers to the numerical index, whose values are in the range of 0 to 100. Value 0 shows the pavement in a much damaged condition and value 100 shows the perfect pavement. The location surveyed was the road section of Triwidadi along 4000 meters at Sta. 14 + 000 - Sta. 18 + 000. As found in the analysis conducted, the result of Pavement Conditional Index (PCI), it could be identified 13 types of damage and percentage values, including Aligator Cracking by 6.08%, Bumb and Sags by 6.98%, Corrugation by 0.90%, Depression by 5,86%, Edge cracking by 11.04%, Longitudinal Cracking by 22.07%, Patching and Utility Cut Patching by 13.06%, Polised Agregat by 18.02%, Potholes by 8.33%, Shoving by 0.23%, Slippage Cracking by 0.23%, Expand Upheaval by 0.23%, and Raveling by 6.98%. The total index was 34.75% which was included in the poor category with the handling time as revealed by PCI Decision Matrix is immediately reconstructed.

Abstract
The fission-product gas pressure and radioactivity analysis of a sub-critical assembly for Mo-99 production (SAMOP) experimental facility have been done. The SAMOP reactor core is an annular tube surrounded by a ring of fuel tubes, fueled with low enriched uranyl nitrate UO2(NO3)2 of 300 g U/L. The reactor is designed to be operated at 100 to 120 hours periodic operation per batch. The calculation method is done by using ORIGEN2 computer code, for the condition of the maximum fuel temperature 54 C, 120 hours reactor operating time, and neutron flux is varied from 10^10 to 10^12 n/cm^2s. The result shows that the inventory of the gaseous fission products consisted of xenon, radium, helium, and tritium isotopes with the total activity of 1.3576x10^13 Bq (366.9158 Ci) and total gas volume 0.0969 cm^3. Total pressure due to the fission product gases is 5.78 kPa, this is very small, therefore the pressure monitoring in the SAMOP reactor core is not necessary. The isotopes of xenon and krypton are the major contributors to the total gas pressure. The release probability of these volatile fission products is very small, whiles SAMOP reactor does not have open nuclear material, therefore no special ventilation system is required.

Abstract
The ducting system has considerable energy losses in channeling cold air in a tall building. At the square elbow 90-degree, the pressure drop due to friction loss, separation loss, and secondary flow. An increase in pressure drop can increase the amount of energy consumption needed. The method identified in reducing this energy loss is by using passive flow control. This study aims to identify the characteristics of the fluid in the ducting with variations in the circular turbulator gap. The variation of the gap between circular turbulator and 90-degree inner elbow (g/Dh) is 0.01 - 0.05. The ducting model used is a square duct with a hydraulic diameter of 125 mm. The results showed that the addition of circular turbulator g/Dh = 0.02 reduced the pressure drop by 20.52 percent. The use of circular turbulator on the 90-degree inner elbow causes the phenomenon of separating and reattaching. The shear layer deflected from the circular turbulator meets the free stream momentum so that it has high turbulence intensity. This fluid momentum reattaches the curved surface of the 90-degree inner elbows and can resist wall shear stress.

Abstract
Some of the Indonesian people who struck by the crisis of national character must get proper handling. Some of these national crises lead to acts of global terrorism. One effort to deal with the national character crisis, especially at the level of elementary school students, is to teach songs with national character. In the period of 2017 until the beginning of 2019 the learning of songs with national character was held as part of the national character campaign. The study found a number of simple computer technology instruments that can be used in learning songs in the classroom. Several technology package options can be used. In this study also found a number of procedures that must be prepared by teachers in learning songs with simple technology in class. However, if the teacher is not good enough in teaching learning material, those simple technology can become less effective.

Abstract
Most farmers in Japan have joined in farmer-s cooperative that is Japan Agricultural Group (JA Group). The role of JA is very important in improving Japanese farmer well-being. Basically, JA collectively purchase the materials necessary for agricultural production and market agricultural products, also involved in a wide range of business activities. Hence, this study aim to explore the marketing strategies that were conducted in four places of agricultural promotion in Minami-uonuma City Niigata Prefecture and Obuse Town, Nagano Prefecture, Japan. This is descriptive qualitative research, data were collected by field study, interview with key informant and documentation. The key informants are the manager of the organization and official government. Collected data are presented descriptively. The result show that basically Japan Government and JA group have good collaboration to market farmer-s product regarding four important aspects: first, developing marketing centers that integrated with local resources such as Michino Eki, Agripark Yairo, Obuse Town. In these spots, farmers can sell their products fresh and processed directly to consumers and have strong power to determine the prices of their products. Second, increasing both quality and continuity of products is an important priority (freshness and use of chemicals are very strictly regulated). Third, promoting their product in many aggressive ways such as online, social media, brochure, leaflet, events, and always update information about their product.

Abstract
Transition process in which Maja District rural areas become more urban in character make this district area classified as a peri-urban area. This study aims to determine the changes in socio-economic conditions of the peri-urban area of Maja District, Lebak Regency, which are the objects of independent new city development in accordance with the 2015-2019 mid-term development plan. Changes in social conditions can be seen from changes in demographic conditions, education and population density of peri-urban areas. Changes in economic conditions can be seen from changes in the characteristics of land use, changes in peoples livelihoods and infrastructure that sustain the economic life. This research is a descriptive study using quantitative methods. The data used are secondary data obtained from the authorized local government, interviews with stakeholder and field observations. From this research, it is known that the construction of the new city of Maja is one of the governments efforts to restrain the pace of urbanization to Jakarta while providing alternative housing for people who are now more active in Jakarta and its surroundings. At present, development in the new city of Maja is being carried out and making changes in the socio-economic conditions of the community towards a better direction. In the short term according to the 2015-2019 mid-term development plan it is difficult to realize Maja as a new independent city so that it still plays a role as a new supporting city.

Abstract
The teaching of integrated skills of English to EFL students in Indonesia is needed to provide them with the balanced learning among the four skills, i.e reading, writing, listening, and speaking. This is an ICT-based English instructions designed for the Z generations at Grade IX of SMPN 5 Panggang, Gunungkidul, Indonesia who have limited facilities for technologies. The infographic project adapted the process approach of formal speaking (Nation and Newton, 2009: 125-7), the process-based writing (Hyland, 2003: 10-14) and the multimedia-based instructional design (Lee and Owens, 2004). The project consists of some steps, they are: (1) topic selection; (2) design (organizing ideas); (3) development; (4) evaluation; and (5) publication. The products of the infographic project are five infographics of report texts about animals. They are: (1) “Green Turtles”, (2) “American Alligators”, (3) “Orangutans”, (4) “Chameleons”, and (5) “Gorillas”. They were uploaded in social media Instagram (IG) and Facebook. The finding shows that Infographic project is believed to: (1) make students happy during the English instructions; (2) improve students- participation in the English instructions; (3) improve students- comprehension of a report text, (4) improve students- speaking skills in giving information about animals; (5) improve students- ICT literacy especially in creating infograpic through www.canva.com.

Abstract
The Philippines is the last country in Asia and one of only three countries worldwide with a 10-year pre-university cycle (Angola and Djibouti are the other two) thus Republic Act 10533 other known as “Enhanced Basic Education Act of 2013” was enacted. The Act provides the K to 12 Basic Education Program law, which covers Kindergarten and 12 years of basic education (six years of primary education, four years of Junior High School, and two years of Senior High School to provide sufficient time for mastery of concepts and skills, develop lifelong learners, and prepare graduates for tertiary education, middle-level skills development, employment, and entrepreneurship (deped.gov.ph). To use the Mother Tongue (MT) as a form of language instruction from kindergarten until the third year of primary school, is another major reform under the K-12 program. Philippines is known to be multi-ethnic, multi-lingual country thus implementation of the MTB-MLE program is quite a challenge. It cannot be denied that teachers play a major role in the success of the language policy. Their positive viewpoint towards the implementation of the MTB-MLE drastically affects the implementation. It is for this reason that this study was being conducted to determine the perception of the teachers in the implementation of the MTB-MLE. This study is a descriptive-qualitative type of research because it focused on the experiences and perception of teachers in implementing the mother tongue based multilingual education in their schools. Descriptive in nature because it describes the implementation of the said program. It records the feelings of the teachers as the direct implementers of the MTB-MLE program. Based on the results of the study, MTB-MLE program is perceived to be an effective program. Teachers are ready as implementers of the program because they had attended seminars and training related to this purpose. The non-availability of instructional materials somehow brought hindrance to the implementation of MTB-MLE. In the case of the instructional materials it should have been pilot/field tested. Department of Education (DepEd) should see to it that when a certain program will be implemented, all kinds of support should be complete. Early preparation should have been instituted. Moreover, there were three major problems met by the teachers: multilingual environment; insufficient instructional materials; and difficulty in translation.

Abstract
Listening and speaking skills clearly turn into a critical ability for language students as those skills facilitate the fruitful adaptation particularly on the advancement of education and technology. There have been numerous studies investigating the implementation of blended learning approach that support the enhancement of students- language skills. The underlying reason of its inclusion is for it can improve students- learning independence, intuitiveness, and achievement. Additionally, it assists students to meet their individual leaning objectives and needs at their own pace, as it offers different learning speeds and styles. The current study aims at designing and evaluating the quality of the blended learning approach for listening and speaking course. In addition, it also aims at investigating the students- attitudes towards its implementation. This study utilizes questionnaire, semi-structured interview, instructional model hosted in the learning management system as the data gathering instruments. The study indicates whether the blended learning instruction model being designed is suitable and fits the students- learning needs. Furthermore, how students perceive the blended learning approach to the listening and speaking course towards their language skills are revealed.

Abstract
The results of previous studies have obtained several bacteria that are tolerant of plastic waste. However, its ability has not been tested as biodegradation of plastic and biological fertilizers. Therefore this research is intended to test the potential ability of these bacteria as biodegradation of plastic waste and as biological fertilizer by using Gas Chromatography-Mass Spectrophotometry (GC-MS). GC-MS analysis results on SP6 isolates as plastic-tolerant bacterial models, have obtained 5 specific secondary metabolites which act as biodegradation of plastic with the composition: Malic acid (?4?6?5) 1.85%, Xanthine (?5?4?4?2) 1.08%, Myo inositol ( ?6?12?6) 1.32%, γ Glutamyl alanine (?8?14?2?5) 0.85% and Ribitol 5 phosphate (?5?13?8?) 1.30%. In addition, the isolate was also able to synthesize several phytohormones with the composition: α Aminobutyric acid3 (C4H9NO2) 1.20%, Indoleacetic acid (C10H9NO2) 1.85%, Kinetin (C10H9N5O) 1.19%, Kinetin glucoside (C16H19N5O7) 1,19 % and Benzyladenine 9 glucoside N6 (C18H21N5O5) 1.31%, thus the bacterium has a double potential, besides being able to degrade plastic, it also has the potential as a biofertilizer.
