Abstract
The purpose of this research was to analyze the comparison of the soundness level of state-owned public banking with private-owned banking in Indonesia during the period 2012-2016. This research was conducted using the Capital approach with CAR ratio, Risk Profile with NPL & LDR ratios, and Earnings with ROA & NIM ratios. The sample of this study amounted to 8 banks consisting of 4 state-owned banks and 4 private banks. Normality testing uses the Kolmogorov-Smirnov test and hypothesis testing using the Independent t-test also Mann-Whitney test U-test. From the results of this study it is known that there are significant differences in ROA & NIM ratios, while there is no significant difference in the CAR, NPL & LDR ratios. Whereas, based on the average CAR, NIM and ROA, state-owned banking is better at a level of soundness compared to private-owned banks, and the NPL & LDR ratio of private-owned banks is better than the state-owned banking.

Abstract
The piezometer is generally used as a porewater pressure gauge at the core of the dam. Piezometer is placed in the upstream and downstream where if the upstream porewater pressure is higher than the downstream, the dam is in good condition. The piezometer that is planted in the dam can be damaged and the replacement is not possible to be done because it is embedded deep in the core of the dam. Because the piezometer basically measures the height of the water table to the piezometer so that if the height of the water table in the core of the dam is known, so the value of the pressure in the dam is known also. One way to find out the water level is to measure it by using georadar. The purpose of this study was to determine the feasibility of georadar to finding the porewater presure. As a case study, this study was conducted at the Sutami dam which still has a functioning piezometer. Measurements are made by B-scan at the location above the piezometer in the middle of the dam. The Radargram from the GPR is then analyzed in two steps, namely (1) determining the type of core material of the dam, and (2) calculating the pore pressure based on the water level and comparing the result with actual value from piezometer. The result shows that georadar can be used as a substitute for piezometers to measure porewater presure.

Abstract
The mean-variance method introduced by Markowitz is considered as the fundamental basis of portfolio theory but the method introduced by Markowitz is only used for single periods while in reality Pension Fund institutions must carry out multi-period investment activities. Looking at the limitations of the mean-variance method introduced by Markowitz, research on portfolio optimization for multiperiods known as multiperiod mean-variance emerged. Based on these conditions, this study discusses about the application of the mean-variance multiperiod method carried out by Yao, Lai, Ma & Jian (2014) which considered mortality risk and changes in contributions. In this study using 4 scenarios using assets included in the LQ45 index as risk assets and T-Bill 3 months as risk-free assets during the 2014-2018 period. The results of this study indicate that the smallest return is owned by the asset allocation model without contributions (scenario 2) because there is no additional membership fee, so the amount of funds that can be invested is more limited so the expected wealth terminal is smaller than other asset allocation models. Then the asset allocation model without mortality (scenario 3) provides the highest expected terminal wealth compared to other asset allocation models, this is because in the absence of mortality factors the Pension Fund investment will not be forced to stop before the retirement period ends so that the portfolio return is higher than other models. While the asset allocation model using risk free asset references (scenario 4) has a higher risk with the same return when compared to asset allocation using reference to risk assets (scenario 3) this shows that the asset reference used affects the return and risk in allocation of Pension Fund assets at the end of the investment period.

Abstract
This study analyzes the influence of perceived quality of mobile payment application towards customer loyalty. Cognition-affect-behavior model is used in this research where cognition stage includes perceived quality which divided into delivery quality and outcome quality. Customer trust, satisfaction and switching barriers included in affect stage and loyalty treated as a behavioral intention. All data in this research were collected from 342 respondents who is a mobile payment user in Indonesia. Then, a model has been estimated using structural equation modeling (SEM). The results indicate that delivery quality and outcome quality that formed through interaction with a mobile payment service positively affects customer trust and satisfaction, which in turn influence loyalty. However, customer trust does not positively influence to loyalty but has to be mediated by satisfaction. Loyalty itself has a positive effect on trust and negative effect on satisfaction. And lastly, switching barrier has a positive effect on loyalty. This developed model helps to improve the understanding of the creation of loyalty in a mobile payment context.

Abstract
Biasanya Hukum Kedua Termodinamika diperkenalkan dalam kuliah Termodinamika, sebagai suatu pernyataan dari Rudolf Clausius dan Lord Kelvin serta Max Planck, dan kemudian konsep Entropi diperkenalkan secara tersendiri melalui hipotesis atau teorema Clausius berupa suatu integral melingkar. Suatu cara yang lebih tampak sinambung adalah dengan langsung memperkenalkan konsep Entropi berdasarkan analisis pernyataan Clausius tersebut. Manfaatnya adalah, bahwa konsep efisiensi maksimum bagi siklus mesin kalor dan siklus mesin pendinginan lalu langsung dapat diperoleh dengan sederhana. Selanjutnya interpretasi molekular dan statistik Ludwig Boltzmann dapat diperkenalkan sebagai suatu upaya memahami keterarahan perkembangan entropi total suatu sistem terisolasi. Ada baiknya kemudian perkenalan Hukum Kedua Termodinamika ini ditutup dengan suatu catatan yang bersifat asumsi yang tidak dapat dibuktikan secara ilmiah-terukur / metafisika, agar pertanyaan “mengapa begitu?” dapat memicu rasa ingin tahu mahasiswa tentang ada tidaknya suatu tujuan, dalam jagad raya ini.

Abstract
Poverty is one of complex problem engages many stakeholders that exist in society. Government as the highest authority will not be able to do everything, therefore it certainly requires other parties who are willing to help overcome poverty especially in the city of Surakarta. The solution offered by researchers is through Collaborative Governance to overcome this poverty problem. This study employs literature review approach to analyze how the patterns of poverty reduction based on the results of previous studies. The method utilize literature review using 2 keywords that are collaborative governance and poverty. The results revealed that there are at least 3 patterns in poverty reduction, that establish a poverty alleviation agency, then initiation from the private sector and finally a local wisdom approach. However, in Surakarta City, there can be at least 2 patterns, that are establishing a special agency that handles poverty, and the second approach is based on local wisdom.

Abstract
The concept of the state of law or often referred to Reachstaat, the rule of law or etat de droit is a concept of the state that prioritizes law as the basis for carrying out an action taken by the state. Based on the state of laws principle, namely that the Government is organized according to the law, in carrying out a government it must refer to the laws and regulations that serve as guidelines for the organization of a country based on the wishes of the people. The types of laws and regulations are contained in Law Number 12 of 2011 concerning the Establishment of Legislation. The product of legislation is made by the executive institution, namely Government Acts / Regulations Substitute the Law; Government regulations; Presidential decree; Regulations of the Supreme Audit Agency, Bank Indonesia, Ministers, agencies, institutions or commissions established by the Act or the Government at the behest of the Law that all must be harmonized and synchronized so that the good legislation can be formed. The research method that will be used in this study is a combination of normative research supported by empirical data on field research. Synchronization and harmonization (preview) are currently only carried out in a number of draft laws and regulations, for example the draft Initiative Law from the Government, draft Government Regulation (PP) and draft Presidential Regulation (PERPRES) carried out by the Ministry of Law and Human Rights through the directorate general of legislation, while there are still many legislative products from legislatures that are not harmonized, such as legislation in accordance with article 8 paragraph (1), namely regulations on agencies, institutions, ministries, and others. So all products of legislation made by the executive and legislative institutions must be harmonized in advance so that every legislation does not collide with each other

Abstract
Shrimp agroindustry deals with processing raw shrimp into various frozen shrimp products. The production of frozen shrimp products are continuously made based on consumer demand with uncertain pattern. To sustain this production, raw materials, which in this case is, raw shrimp have to be continuously available at all times. Therefore, working integratedly with suppliers to satisfy customer demand is a fundamental goal for shrimp agroindustry. A selection of suppliers in agroindustry is determined according to three criteria, namely the quality of raw materials, delivery time, and payment scheme. These criteria are used as a measurement to evaluate supplier perfomances by decision makers. To minimize uncertainty and subjectivity of decision makers when choosing suppliers, a fuzzy inference system method is proposed. The outcomes of the fuzzy inference system method are a set of rule base that is used to evaluate suppliers in shrimp agroindustry

Abstract
Upgrading local companies is one of the key concerns of host government, especially in developing countries, in the age of Global Value Chains (GVCs). GVCs provide both opportunities and threats for host countries. One side, GVCs are the window of opportunities for local companies to catch up with the global leaders. On the other hand, GVCs could provide only limited impact on host country economic development by only seeking and exploiting the location advantages of host country. This paper aims to elaborate some common upgrading challenges faced by local companies when they engage in GVCs. Four main upgrading challenges are identified, namely: hyper-dependency on a single buyer, financial pressures, inconsistent industrial policy, and global competition. A single case study research is employed to illustrate these situations and how these challenges inhibit a leading and potential local company to grow and upgrade its position in GVCs. Astra International and its automotive subsidiaries (Astra) are chosen as the case study for number of reasons. First, Astra is originally from Indonesia. The company was established by Indonesians and locates most of all their businesses and value chain activities in Indonesia. Secondly, Astra is one of the largest Indonesian companies which has about 200 subsidiaries and employs over 200,000 workers. Thirdly, this study case gives very rich insights for other Indonesian local companies and government how to grow, manage and support businesses in the age of GVCs. Several implications for managerial strategy and policy recommendation are also discussed.

Abstract
In a science education, various formative assessment with online tools and interfaces are gaining an increased attention. It allows science students to be more involved in operational circumstances and to accomplish an enhanced outcome. This study presents a formative assessment with online tools to analyze students- outcomes to check its effect in university flipped science classroom. For the study, a total of 311 students participated with a randomized experimental setting in a general science course during 2014 to 2018. Participants did not have particularly any experiences with online tools of formative assessment: randomization not on the basis of any criteria manipulated and no constrains imposed. To find out the students- outcomes toward the course, the proposed study was managed on diverse assessments along with students participated for the whole curriculum course: feedback of students, data of students- outcome and log files. The results indicate that positive effects on outcome of students. Thus, their positive effects were higher if students used the online tools of formative assessment to a greater extent. Among different levels of students, high-performance students achieved higher outcome and better effect by formative assessments with online tools. Hence, current traditional science learning difficulties and problems could be overcome based on the results attained, which is showing a meaning approach.

Abstract
This paper presents a methodology to prioritize suitable criteria and their sub-criteria for science education through flipped e-learning programs. Here, an operational technique is applied together with multi-criteria decision analysis (MCDA) and fuzzy-decision-making trial and evaluation laboratory (F-DEMATEL) method to outline different components such as instructors, courses and laboratories, materials, technological infrastructures, securities, etc. in flipped science education. In the context of MCDA/F-DEMATEL hybrid and participatory approach, we have selected three major criteria after experts- consultation through analytic hierarchy process (AHP), that is, flipped-learning, science-education and technological-advance. Their weight coefficients and influence are calculated to rank their suitability in a more long-term learning program. With the weighted linear combination (WLC) and sensitivity analysis, the most suitable criteria and sub-criteria are selected for science education through flipped e-learning programs, i.e. technological-advance and infrastructure of information technology. Hence, these operational methods have possibility to be reused and reapplied in different studies and parallel education settings if there are available data. Thus, because online-learning methods are accelerating its development into various learning domains, it could resolve decision-making problems on flipped science education.

Abstract
The research aims to enhance student-s awareness about the environment through project-based learning. In learning process students are expected to solve school environment problems of waste management . The study was conducted on the students of grade X, in one of the Vocational Schools in Bogor for 3 meetings. Students are given worksheet as a guide for designing waste treatment projects. The researcher used six stages according to Doppelt (2004), namely: 1) Design purpose; 2) Inquiry field; 3) Solution; 4) Choosing the preferred solutions; 5) Operation step; 6) Evaluation. Indicators of awareness for the environment used Dunlap and Liere (2000) instruments, including: 1) fragility of natural balance in the school environment; 2) ecological crisis in the school environment; 3) the reality of limited natural resources in the school environment; 4) Anti-anthropocentrism of students in the school environment; 5) rejection of exceptionalism.The results showed an increase of awareness towards the school environment with N-gain score category is medium (N gain= 0,41). Students also appreciate and maintain the school environment.

Abstract
The research aims to describe pupils inter-dialogue during learning polyhedron. It based on learning obstacle. In didactical obstacles are found problems of conceptual interrelation, thinking continuity, and limitation experience of pupils in the polyhedron concept. So, The researchers designed a didactical design to minimize the learning obstacle by creating a more organizer and solve learning trajectory. The design implementation done on the pupils of grade VIII in Bandung during 3 continuous meetings. Inter-dialogue is expected to emerge when didactic design is designed so students dialogue with group friends to find solutions for solving problems. Dialogue that produces critical questions is commonly known as socratic dialogue. The main idea in socratic dialogue is the teachers task is not to give knowledge or provide information to students but the task of the teacher designing a learning situation where students will ask critical questions. The researche using phenomenological studies to uncover pupils experience. By using Nonaka theory, the researcher found the pupils knowledge. The results showed the pupils intra-dialogue system in solving the polyhedron geometrical problem of phenomenological studies.

Abstract
Maintaining an effective risk management procedure can counterbalance a critical effect on supply chains. The Agri-food supply chain has characteristics that are unique and complex if compared with a conventional supply chain.Sustainability risk management in the supply chain is the key to a competitive organization in the long term. The aim of this paper is to review current research on sustainable risk management in the Agri-food industry chain. These reviews were arranged in steps systematically, ranging from searching related to review of supply chain sustainability risk management (SCSRM), reviewing the general framework of SCSRM and the framework of Agri-food SCSRM. Selection of literature review papers in the period 2010-2019, and obtained 30 papers. Risk aspects were analyzed using a multi-dimensional approach (economic, social, environmental, technical, and institutional) that influences the sustainability of the Agri-food industry. The results show that there are few studies focusing on risk management to achieve a sustainable supply chain system. Some studies only focus on Triple Bottom Line elements (economic, social, and environmental). Sometimes, these studies do not consider risks from other elements such as technical and institutional aspects that can be influence the sustainability of the Agri-food industry. Technical aspects such as the reliability of technological systems and institutional aspects as policymakers support sustainability in a business process. The contribution of this paper is to provide an initial theoretical framework to guide researchers in analyzing risk through a multi-dimensional approach to sustainability.
