Abstract
In running a business, entrepreneurs need to maintain consistency and business continuity. Unfortunately, the number of successful young entrepreneurs in Indonesia compared to those who are unsuccessful is still very small. This study aims to found out the process and factors that construct the entrepreneurial resiliency who had experienced a downturn in business but had succeeded in generating and sustaining a stable business after the downturn. This research was conducted using case study approach with in depth interview as data collection tool. The results of the study indicate that the factors that construct entrepreneur resilience are social support, self-regulated, self-efficacy and adaptive coping strategy. The strategic implementation of emotional-based coping especially religious coping, and persistently performing concrete problem-based coping help the the entrepreneur in strengthening and developing the business. The results of this research could be used as a reference to increase the resilience of entrepreneurs who experience severe challenges in their business, to be able to get back up for success.

Abstract
Natural fiber has several advantages compared to synthetic materials. The advantages of natural fiber include low prices, low density, renewable and biodegradable materials and not harmful to health. Many attempts were made to explore new natural fibers and the use of plant fibers by different industrial sectors, such as composites for automotive applications and to replace synthetic fibers. Bamboo is one of the natural fibers that has many advantages.As a construction material, the use of bamboo for structural materials has good strength, easy to implement,low priceand environmentally friendly. Bamboo can be used in construction planning because based on its properties the mechanical strength of bamboo has a high tensile strength and high compressive strength so that it can be used for soil reinforcement. A good bamboo has a compressive strength and optimal tensile strength. As shown by the laboratory results, the relationship between tensile strength and compressive strength of bamboo is directly proportional to the results for Apus Bamboo which has a greater compressive strength than Javanese bamboo species which is 37.42 mpa for Apus Bamboo and 27.4 mpa for Javanese Bamboo. For tensile test results showed similar results, with Apus Bamboo having greater tensile strength on Javanese type bamboo which is 225.7 mpa for Apus bamboo and 43.76 mpa for Javanese type bamboo.

Abstract
Background: A depression in elderly was known as a life-threatening health problem in Indonesia, particular in Magelang City. The initial study at Gelangan Village documented that depression is currently being a concern in elderly population. Although a number of studies were undertaken to overcome depression, however, a relevant study that conducted in Gelangan Village has received little attention from the local nursing researcher. Therefore, this study was initiated to describe the relationship between ritual activities and tendency of depression among elderly. Purpose: The study aimed at investigating the relationship between ritual activities and the tendency of depression in the elderly at the Ngudi Rahayu Elderly Integrated Health Service Center (Posyandu) in Gelangan Village, Magelang City in 2019. Method: Correlational design that combined with the cross-sectional method was thoughtfully chosen to answer the research question of the study. A total of 40 respondents were involved. In this study, two variables were selected as follows ritual activities (variable one) and the tendency of depression (variable two). The Spearmans rank correlation was taken into consideration to measures the strength and direction of the relationship between variables. The significance level was considered at 0.05 for hypothesis testing. Results: The finding of the study showed that relationship between ritual activities and tendency of depression is statistically significant (p < 0.05). Moreover, the level of correlation is fair as expected by the researcher (-0.448). The negative correlation was also obtained from the study that is to say when the variable one increases, the other decreases. Conclusion: The relationship between ritual activities and tendency of depression is statistically significant (p < 0.05) which can be justified that when the variable one increases, the other decreases. Suggestion: With the result of this study, it is expected that this ritual activity can be applied to nursing care especially on mental health.

Abstract This research aimed to show the relationship of husband authority in the form of intervention on wife political rights. The collection of data was carried out through interviews, observations, and literature studies in order to help answering the research questions. The results showed that the husband intervened in his wifes political rights. This was what escaped the attention of governments and gender drivers in protecting the political rights of wives. So far, the government has not maximally protected the rights of wives in the public sphere. Whereas the private/family institution is the root of the wifes political rights being unprotected. Thus, the family institution becomes the first place to lose the wifes independence in obtaining her political rights.

Abstract
Bamboo is an abundant material and easily available in Indonesia. In addition to having high compressive strength and tensile strength as well as ease of obtaining and low prices, bamboo is a consideration and focus in developing in the world of construction today. In this study, bamboo is used for soil stabilization, where bamboo is used in the form of fibre. This research focuses on the strength properties of various types of bamboo. The focus is to investigate the relationship between the maximum tensile strength of bamboo and the flexibility of bamboo in soil stabilization. This is very important, because bamboo fibers used for soil stabilization rely on their tensile strength rather than their compressive strength. Thus, the optimum tensile strength and flexibility of bamboo must be of particular concern. From the results of the study of the tensile strength of two types of bamboo, namely Apus Bamboo and Java Bamboo, the Apus Bamboo results were found to have a higher tensile strength of 225.57 mpa with maximum flexibility of 19.99 mm and 43.76 mpa for tensile strength of Javanese Bamboo with a level of flexibility of 10.26 mm.

Abstract
As part of the international community, Indonesia is an active country to participate at international treaties. To show it commitments, Indonesia has been adopted those treaties into domestic legal system. However, the existing law does not regulate the clear status of the treaties ratified by Indonesia. It is merely regulate about two classifications of treaties whether it needs parliament approval or not. With this situation, this study proposes a new model procedural legislation for the adoption of international treaties under Indonesian domestic law. With normative legal methodology, this study concludes that any effort from Indonesia to ratify treaties must be delivered to the house of representative at the beginning of process before ratification. This must be assisted with the academic research which contains the holistic explanation why the Government should ratify the treaty. The statutory law on treaty ratification must not only mentioning the ratification decision but also specifyng the whole provisions of the treaty that shall has direct binding effect in Indonesian territory.

Abstract
This study aims to examine the effect of earnings management on the relationship between dividend change, and future earnings differed between family companies and non-family. These research use companies on the Indonesia Stock Exchange in 2009-2017. One of the essential predictions from the dividend-signaling hypothesis is that changes in dividends positively correlated with changes in future earnings. By using a regression test, the findings of this study indicate that in family companies dividend changes give a negative reaction to future earnings. However, the interaction of dividend changes with earnings management harms future earnings only in the second year. Therefore the family company conducts earnings management, thus negative impact on future earnings. The converse result shows that changes in dividends at non- family companies produce a positive reaction to future earnings in the first year. There is an interaction between dividend changes with earnings management actions reacting positively to future earnings in the first and second years. Furthermore, using the coefficient difference test, it was found that there was a difference in the effect of earnings management on the relationship between changes in dividends and future earnings. This result differs between family companies and non-family companies.

Abstract
Borobudur Temple is one of the 10 priority tourism destinations in Indonesia. Borobudur ranks 1st in performance analysis and projections, but the existence of Borobudur Temple has not had a major influence on the economy in the surrounding area. As an illustration, the length of stay or tourist visit to Borobudur is less than 3 hours, it causes on the minimal income of the Borobudur District community. Following up on these problems, the Ministry of BUMN established the Balkondes (Village Economic Center) program which aims to improve the economy of the Borobudur District community. The existence of Balkondes under the auspices of PT. CBT Nusantaras management as a program implementer from the Kementrian Pariwisata (Ministry of SOEs) collaborates with state-owned companies as partners who foster each village as a storefront and tourist-aware driving room. Currently there are 20 villages that have Balkondes with development programs tailored to the potential of each village in Borobudur District. This study aims to see how the role of PT. CBT Nusantara Management as the program implementer in maximizing the potential of villages as a tourism sub-system of Borobudur. The methodological approach used is qualitative explanatory with purposive sampling. The theory used to analize this study is the theory of the Role of Community Based Tourism. The results showed that during the three years formed, the existence of Balkondes was still constrained in several aspects, especially in the process of making the program, because it had to be adjusted to the potential of each village that had not been managed, both natural resources and the human resources. Changing the mindset of rural communities related to the tourism potential development program in Borobudur District is a major challenge for PT. CBT Nusantara Management. The role that can not be maximized given the problems in the village are very complex. The Pentahelix synergy strategy launched by the Ministry of Tourism is expected to further maximize the role of PT. CBT Nusantara Management because tourism development is not only the responsibility of one party but all parties ranging from academics, the private sector, the community, the government and the media.

Abstract
This paper elaborates the role of teacher in counteracting the influence of the transnational ideology of Khilafah to high school students which has potentials to give birth to religious radicalism and endanger their nationalism. This qualitative research with ethnographic approach took place at SMA N 1, SMA 2 and SMA N 3 Purwokerto. The reason for choosing Purwokerto as the location of the research is because it is a student city with Javanese Banyumasan cultural characteristics, while choosing high school students as the sample is due to their unstable and dynamic personality and their important role in determining the model of religious and national life in Indonesia in the future. Based on the research, 3 (three) conclusions were revealed. First, the pattern of students religious views in general is moderate. Some students recognize the concept of Khilafah with a relatively minimal understanding of information that does not have implications for their personality in religion and nationality. Secondly, most students are familiar with the concept of khilafah through the internet, social media, and social and scientific interaction. Third, as a form of awareness of the dangers of transnational ideology (such as the ideology of Khilafah), teachers build and foster students- awareness both through structured learning and the development of religious activities in schools so that they are careful in associating and wise in utilizing the internet and social media thus avoiding the influence of radical religious ideology that endangers nationalism.

Abstract
This article aims to determine the role of the Dewey Decimal Classification (DDC) library system in the implementation of the school literacy movement (GLS) program in Borobudur State Elementary School (SDN) 2. The research subjects were students. The research instrument used was observation and documentation. The results showed that: The efforts undertaken by schools in implementing school literacy programs were: (1) Use of Dewey Decimal Classification (DDC) in school libraries, (2) Bringing books closer to students by creating reading areas outside the room, and ( 3) carrying out various forms of literacy activities in the classroom and through Indonesian language lessons. The obstacles faced by schools in GLS are: (1) the library room that is used as a classroom (in the process of renovation), and (2) the teacher lacks understanding of the application of the literacy movement. Thus, the implementation of the GLS program at SDN Borobudur 2 needs to be increased to the development stage by involving various parties.

Abstract
This study is aimed at analyzing the inadequacy of theories on causality in criminal law to be applied to the offenses of environmental damage/pollution, and ideas about its use in relation to characteristic of environmental offense. This study belongs to normative legal research using the statutory, philosophical, and conceptual approaches. The study reveals that today, the environmental is philosophically placed both as a legal interest and victim of crime. Such crimes can directly threat or harm the environment. The environmental damage pollution also threatens the rights of future generations to enjoy clean and healthy environment as an impact of principle of ubiquity. The amount of environmental damage is also difficult to calculate and the time span can occur decades later after the crime was committed. Therefore, the proof of causality must shift from the proof of factual consequences to the proof of effect under the basis of prediction of scientific knowledge. The transformation of scientific evidence into legal evidence is the main key in proving the emerge of environmental damage/pollution.

Abstract
Modular design of battery pack for electric vehichle (EV) is an important things to consider. Because in modular battery pack, cost to manufacture can be reduced also easiness in handling. Modular battery pack also meant to be easily swapped between every modules. In this paper were presented the thermal analysis of modular battery pack that generate heat during charging and discharging process. heat flux generated by the batteries will affect its surrounding thus increase the temperature of the batteries. Thermal analysis simulation were conducted to ensure the heat generated not exceed the maximal operational temperature of the battery cells that can reduce the battery life. The simulation is done by analyzing the heat power generated by the cells, the effect on surrounding, and heat generated by the current flow in the circuit. Simulation result were showing that the temperature rise in the battery pack not exceed 60°C, in the surrounding or even in the battery cell. It is found that these two parameter, lower cost to manufacture, and thermal stability having the largest effect on reliability. Hopefully futher studies of thermal management on battery pack conducted to generate reliable design of modular battery packs

Abstract
One of the fault detection of three-phase electric motor isolation is caused by unbalanced voltage. The National Electrical Manufacturers Association (NEMA) standard for unbalanced voltage is 1%. Fault detection of electric motor isolation is too complex to be modeled in mathematical form. Therefore, this paper proposes to model the electric motor isolation caused by unbalanced voltage using the Radial Basis Function Network (RBFN). RBFN is implemented for training and testing data with input variations number of unbalanced voltage, rotation speed, running hours and output variations number of insulation resistance, index polarization. The modeling process is comparing the number of neurons and the learning rate to get accuracy and speed of time. The results of modeling using RBFN obtained Mean Square Error (MSE) of 2.11 e-04 and this method is very well applied for fault detection of electric motor isolation.

Abstract
Lombok is a beautiful island, which has many tourist attractions. The beauty of Lombok island is known by public through local and international media. Many tourists has come to enjoy the beauty of this island, both local and foreign. However, in an instant all changed when the earthquake occurred in 2018. The tourism industries was suddenly empty of visitors. This is certainly worrying, the government and related parties are currently actively pursuing various strategies to turn in the condition of Lombok as before, especially in the tourism sector. However, this cannot provide maximum results if the earthquake issues remain the main discourse in publications. Social media is certainly one of the media that has a direct impact on publications. This research analyze on how social media construction, especially those engaged in the tourism sector in rebuilding positive publications in Lombok tourism industries. The method used in this research is critical discourse analysis of Van Dijk that focuses on the text production process in constructing the message to be conveyed, by taking concern on three accounts of social media Instagram, namely insidelombok, lombokfriendly and lombokhit.

Abstract
The existence and contribution of 28,194 pesantren in Indonesia with 4,290,626 santris is still not optimal, and if it is analogous to the number of entrepreneurs in Indonesia reaching 3.1% of the total population, then the number of entrepreneurs from among santri is 85,813. The output of pesantren is not ready to compete professionally in the job market, however pesantren has a characteristic as forming independent dimensions of santri through religious spirit learning. The aim of this research is to study the theopreneurship education model and its relationship with the development of santris self-efficacy. The research method used was a quantitative-positive approach by conducting a survey of 4 (four) pesantren in Central Java Province that were selected by purposive sampling. Data collection techniques are done by questionnaire, interview and observation. Data analysis used Structural Equation Modeling (SEM). Hypothesis tests used in this research are Chi-square test and t-test. The results showed that the entrepreneurship curriculum variable had the greatest contribution, then the second variable that contributed to improving santris self-efficacy was learning infrastructure and finally the motivation of santris gave the least effect on self-efficacy. Thus, the latent variables of the entrepreneurship curriculum and learning infrastructure have a positive effect on self-efficacy and santris motivation has a negative effect on the growth of self-efficacy.

Abstract
Translation of representation is one representation process which takes an essential role in mathematics learning. Translation capability shown level of students- conceptual understanding. Some processes of translation involve transitional representation. This study aims to describe the occurrence of the process of translating verbal representations to graphs involving transitional representations. This research is a qualitative research. The subject of this research were of the 4th and 6th semester of Mathematics Education Study Program and it was determined by using purposive sampling. The data collection was done by think-aloud tests and interviews. The results shown that there are two types of transitional representation in the process of translation of verbal to the graph representation, i.e. symbolic and numerical representation. The student translates the verbal representation to the graph through two translational processes. The student translates the verbal representation to a symbolic or numerical representation of the representation transition and then translates the symbolic and numerical representation of the representation transition to a graphic representation. The results of this study are expected to increase the findings of previous research and as a consideration in designing learning model.

Abstract
Twitter is a medium of sharing information to express opinions of user events and thoughts. In tweets related to tourist attractions, users write reviews both in terms of location access, service satisfaction, conditions and functionality of existing facilities, and shopping experiences. Twitter data is broken down based on the basic words and then grouped according to the frequency of occurrence of words. There are two groups of words, the positive review group and the negative review group. Decision tree parameters are based on the frequency of occurrence of the word, visitor data trends, and investment value of each tourist location. The results of the decision tree are ranking of potential tourism sites to be developed. 200 Twitter data were collected about tourism in Pekalongan, the highest positive reviews were lawe curug attraction with 97 tweets of positive reviews and 3 negative reviews, while from the decision tree it was found that Welo tourism was ranked first as the priority tourism development object with access value location 80%, service satisfaction 85%, facility condition and functionality 95%, and shopping experience 75% with optimistic increase of visitors by 5% / year

Abstract
This study aims to utilize the use of ultrasonic waves that function as anti-bacterial coliforms in the Kahayan river water. Water sampling is done using the Grab Sampling technique using the Kemmerer Sampler tool. Water used as a sample is in environmental conditions. The application of ultrasonic waves is done by using frequency variations of 20 kHz, 30 kHz, 40 kHz, 50 kHz, and 60 kHz at 5 minutes to get the optimum frequency. Coliform test was carried out by the MPN method, with the stages of the estimation test, affirmation test, and colony calculation. MPN test results show that the use of ultrasonic as the optimum anti-bacterial at a frequency of 40 kHz. Efficiency in this treatment is 89.9%.

Abstract
The need to improve the subgrade of a highway becomes urgent when the vehicle load exceeds the carrying capacity of the soil. Industrial waste, that increase every day, was proposed in this study as an additive or stabilizer to improve the carrying capacity of the subgrade. Testing was done through laboratory experiments of the mixing original soil with Silica Sand waste and Dust Sand Foundry waste in certain compositions. To test the mechanical properties, the Unconfined Compression Strength Test based on ASTM standards was conducted. The unconfined compression strength (qu) value of the original soil was 0.289 kg/cm2. The highest qu value was shown in the composition of the soil mixture with 2.5% SS and 7.5% DSF which was 0.347 kg/cm2. The qu value increased by 20.07% from the qu value of the original soil, and showed a mechanical improvement in stabilizing soil.
