Abstract
Many parties suspect that there is an in-between relationship of fiscal decentralization and the corruption level in the regencies and city. This study aims to examine the effect of fiscal decentralization on the city-wide corruption level in Indonesia. This study used the General Allocation Fund (Dana Alokasi Umum or DAU) of the regency and city, age of regency and city, and location of regency and city as the control variables. The population of this research is all regencies and cities in Indonesia. As the data sources, we used the secondary data. The research sample was selected using the purposive sampling method. Hypothesis testing uses multiple regression analysis, the coefficient of determination test (R2), and partial test (t-test). The statistical test results of the significance level of fiscal decentralization of the corruption level is 0.016 smaller than the significance level of 0.05 (5%). This result shows that fiscal decentralization has a significant effect on the corruption level of regencies and city in Indonesia. The statistical significance level results for the control variable are regency and city-s DAU of 0.081, age of regency and city of 0.221, and regency and city location of 1.222. This means that the DAU, age, and location of regencies and cities have no significant effect on the corruption level of regencies and cities in Indonesia.

Abstract
Semporna is one of the most significant areas in the Malaysian Coral Triangle. This area is known as Semporna Priority Conservation Area (SPCA) and the first Marine Spatial Plan in Malaysia. The shallow water areas within its islands are identified for mariculture activities, fishing sites and tourists destination. One part of the area is Tando Bulong Strait located between Semporna and Bum Bum Island. The excellent natural environment and high marine biodiversity are related to water circulation. The objectives of this study are to determine water current pattern and wave impacts along the strait using numerical modeling. Field surveys of bathymetry, deployment of two Acoustic Doppler Current Profilers (ADCP) for water level and current measurements were done from 1 to 30 August 2017. During this field trip, assessment of current coastal community activities along the strait was also carried out. The field data (water current and water level) were needed for validation and verification of the Delft3D modelling software. The waves, current speed, and direction were analysed and presented on different tidal cycles and seasonal monsoon. Results indicate that tidal cycles and seasonal monsoon play a major role in water exchange of the Strait. The current speed along the coastline is about 0.3 m/s but increase up to 0.37 m/s along the Strait. The model predicted that flood tide current speed during the northeast monsoon flows southwards and increase between 0.6 m/s and 1 m/s at the middle of the Strait south. The wave height during this monsoon is approximately 0.65 m in the north and decreases down to 0.3 m inside the strait. The water circulation is important for the mariculture (seaweed farming), fish cages and marine pollution management. The findings will hopefully lead to a better understanding of the dynamic of the Tando Bulong Strait and improve the future prediction state of the Semporna area.

Abstract
Most of business in the world, including Indonesia, consists of SMEs (around 99% of the total enterprises). With this large number of SMEs must be balanced with good performance in order to sustain and beneficial for the nation, considering their contribution that almost two-third of the national GDP. In this modern era, where everything is connected, we cannot assess SMEs performance solely on conventional products but also need to add other abilities from a founder to be able to bring the company to continue and growth. This, marketing, innovation, learning, and digital capabilities are the key capabilities for the firms in their efforts to achieve superior performance especially in Indonesia. Thus, this research aimed to investigate to what extend founder capabilities are effective on SME performance. To answer the research objective, this research used quantitative method. To assess SMEs performance through founder capabilities in doing marketing, innovation, learning, and digital, a survey was conducted. The samples for the surveys was drawn from difference group of SMEs (micro, small and medium) and across industrial sector, approximately 100 samples were gained for the study. The questionnaire from the survey then analyzed using multiple linear regression to investigate the effect of independent variables (marketing, innovation, learning, and digital capabilities) toward dependent variable (SMEs performance). The author also uses Somers- D for knowing about the effect of control variables (SME industry).

According to the Presidential Regulation of the Republic Indonesia no. 131 of 2015 concerning determination lagging area 2015-2019, Bengkayang is one of the underdevelop districts that lagged in various aspects of life, especially in terms of education which have been formulated by BPS Bengkayang 2018. Basic education is the basis of learning for students to continu their education especially nowaday in this era of industrial revolution 4.0. We conducted research at the elementary school regarding the impact of the teachers economic life on the process of knowledge transfer in the school during the industrial revolution 4.0 era which aims to find the factors that become obstacles transfer of knowledge in the school. This study used a qualitative method with in-depth interviews and observations at Tampe school. The results of this study are that most of the teachers are part timers who have very little salary so they have to look for side jobs in supporting their families and this affects the transfer knowledge in the learning process because of their absence from school. The limitations of the teacher qualifications are in accordance with the project fields so that the transfer knowledge to students cannot be maximally given.

Abstract
The objectives of the study are: 1) to analyze the effects of Capital Adequacy Ratio (CAR), Credit Risk, Loan to Deposit Ratio (LDR), and Net Interest Margin (NIM) to Non-Performing Loan (NPL); 2) to analyze the role of loan monitoring in moderating the effects of CAR, credit risk, LDR, and NIM on NPL. It was a quantitative study. The subject of the study was the Republic of Indonesia Employee Cooperative (KPRI) which had saving and loan business units. Data were collected by conducting documentation (to collect data on CAR, Credit Risk, LDL, NIM, and NPL) and distributing questionnaires (to collect data on loan monitoring). Then, data were analyzed by moderated regression. The results showed that CAR did not influence NPL, credit risk had a positive effect on NPL; LDR did not influence NPL; and NIM had a negative effect on NPL. Then, loan monitoring moderated the effects of CAR, credit risk, and LDR on NPL. However; loan monitoring did not succeed to moderate the effect of NIM on NPL. Based on the results of the study, the cooperatives engaged in the provision of credit need to consider loan monitoring as a very strategic variable to suppress NPL. Thus; it is suggested for the future research to analyze the effectiveness of loan monitoring system at each loaning institution to suppress NPL.

Abstract
Unit-linked endowment insurance with a minimum guarantee not only provides life protection to customers until the end of the insurance contract period but also provides investment protection, especially stock investments that have high returns and high investment risks, so call options are needed to protect investments. This study discusses the calculation of premiums along with the caps and floor limits of premiums on unit-linked endowment insurance products with minimum guarantees using Monte Carlo simulations with stochastic and continuous model and numerical methods. unit linked insurance with stock investment and mortality tables in this study shows that in addition to gender, the initial age of the customer has a policy, insurance contract and amount minimum guarantee, the caps and floor limits of the premium are influenced by the proportion of investment from the premium. The interval between the caps and floor limits of the premium is wider if the investment proportion of the premium is small, so the insurance company can use the caps limits of the premium.

Abstract
Synthetic polymers, including plastic products, are known as one of the most important materials in modern life. They have been widely used in various fields such as energy, information technology, medical, living, and environment. However, most of them cannot be decomposed in the environment causing environmental problems and harmful for living organisms. More than that, the excessive use of synthetic polymer will result in the depletion of irreplaceable natural resources since most of them are made from petrochemical materials. Therefore, development of new biopolymers is expected as a material to replace fuel-based polymers. Among them, chitosan is abundant in nature. Development of polymers with chitosan contributed to solve the environmental and resource depletion problems. It is getting more attention as a new material that mitigate energy waste. Chitosan is a polysaccharide produced by deacetylation of chitin and is extensively used in drug delivery applications. Chitosan is difficult to use industrially because it has high glass transition temperature (Tg) and high crystallinity, and exhibits high elastic modulus and low strain fracture. Therefore, it is necessary to improve their physical properties by blending or copolymerizing with other polymers. Intermolecular hydrogen bonding between chitosan and other polymer molecules is expected to play an important role in stabilizing the higher-order structure. The information related to this interaction can be observed in the low-frequency region (3.3-330 cm-1) using terahertz (THz) and low-frequency Raman spectroscopy. Since low-frequency vibrational spectra are derived from intermolecular and intramolecular interactions, THz and low-frequency Raman spectroscopies can be powerful tools to reveal the formation of higher order structures of not only homopolymer but also polymer blends. In this study, by analysing this low-frequency vibrational spectra, we attempted to elucidate the change in higher-order structure and intermolecular hydrogen bonding formed by polymer blends of chitosan and other polymers.

This study aimed to collect the information of visually impaired children on the ability of personal hygiene on menstrual cycle. 6 visually impaired children were participated in this study. This study used qualitative study in order to explore the several themes related to personal hygiene on menstrual cycle. The data were collected by in depth interview recorded using recorder. Study findings showed that the visually impaired children experience several important facts that contribute to their self hygiene behavior on menstrual cycle. There were five themes obtained in this study. First, lack of knowledge. The theme was represented by the majority of the participant answered incorrectly on the definition of menstruation and the origin of menstrual blood. The second theme was menstruation and beliefs. The majority of participants answered that they afraid to wash their hair on menstrual cycle. The third theme was discomfort. This theme was represented by participants statement of discomfort feeling when delay in changing menstrual pad. The forth theme was emotional. The majority of the participant stated that they aclnowledge their menstrual pad was clean by feeling. The fifth theme was social environment. The majority of the participant obtain the knowledge on menstruation and how to clean menstrual pad from the teacher. Thus, the findings above explain that the visually impaired children still experiencing the disadvantaging issues namely psychosocial and physical problems. The negative feelings such as fear was the everyday obstacles. Myth and beliefs related to mentruation were also identified on this study. The emotional responses expressed by the statement that relying on feeling in conducting self hygiene on menstrual cycle were also identified. The findings from this study were expected to become the source of information in order to develop the psychosocial support to visually impaired children on maintaining their reproduction health.

Abstract
The appropriate treatment method for patient with urinary stones can be determined from the information of the mineral composition of urinary stones. The prediction of the stone type could improve the selection of the interventional modalities. The aim of the study was to determine the type of the urinary stone for each layer based on the value of Housefield Units (HU) from micro CT-SkyScan images. Five samples were cleaned with 75% alcohol and distilled water. Micro skyScan 1173 was used to scan urinary stones with applied current and voltage of 66 mA and 120 kV respectively. NRecon software was used to reconstruct the projected image. Region of Interest (ROI) was set at each layer and analyzed both qualitatively and quantitatively. The determination of chemical constituents of stones/fragments was performed using Energy Dispersive X-Ray Spectroscopy. The chemical compositions of calcium oxalate, a mix of calcium oxalate and calcium phosphate, struvite, uric acid, and a mix of uric acid and calcium phosphate were accurately identified based on the micro SkyScan images with the mean HU for each composition were 1356 ± 188, 1038, 391 ± 151, 391 ±249, and 1384 ± 195, respectively. Micro SkyScan images could predict the chemical composition for each layer of urinary stones. However, more samples are needed for clustering various types of urinary stones based on HU value.

Abstract
The problem with bacteria resistance to antibiotics and antibacterial agents necessitates the development of powerful and effective antibacterial agents. Silver based materials such as silver nanoparticles or silver ions loaded in inorganic materials are examples of the effective inorganic antibacterial agents that can overcome this problem. They are known to have high antibacterial activity against wide spectrum of bacteria (Gram positive and Gram negative bacteria) even at low amount. However, the high usage of silver will create secondary problems which are environmental pollution and also possible bacterial resistance towards silver. Thus, one of the alternative approaches is by creating a hybrid organic-inorganic antibacterial agent using an aluminosilicate material such as zeolite or kaolinite as a carrier system for silver ions and functionalized the silver-zeolite or silver-kaolinite with suitable organic compound. This alternative approach enables lower amount of silver usage but maintaining the antibacterial efficacy due to the synergistic effect of organic compounds that attached together on the carrier system. Our group of research has successfully invented several hybrid antibacterial agents namely surfactant modified silver-zeolite, amine functionalized silver-zeolite, surfactant modified silver-kaolinite, chlorhexidine modified silver-kaolinite and aminoglycoside loaded surfactant modified silver kaolinite. The attachment of organic compound on the silver-zeolite and kaolinite changed physicochemical properties of the raw materials such as the charge was changed from negative to positive and becoming partially hydrophobic and hydrophilic but maintaining the structure of the carrier system. Furthermore, these hybrid antibacterial agents exhibited high antibacterial efficacy against Gram-positive and Gram-negative bacteria as compared to single antibacterial agent loaded on the carrier system. This research could pioneering more hybrid organic-inorganic antibacterial agents in the future since there are many other possible organic and inorganic materials can be combined together in the suitable carrier system and this could lead to lowering the vast usage of silver as antibacterial agent.

Abstract
In Pakistan, banking sector was brought under the umbrella of Islamic financial paradigm since 2004. Many studies has proved that Islamic banking industry (IBI) with its macro indicators was performing well. But no study has been done yet to analyze the role of Shariah compliant financing of IBI in achieving the SDGs. This study attempt to explore this role of Pakistani IBI considering one of the SDGs economic growth. This study used Islamic bank-s products like Salam, Murabaha, Diminishing Musharkah (DM), Ijarah and Istisna as independent variables, while GDP growth rate was used as dependent variable. Keeping in view the availability of data, this study selected thirteen banks; four full-fledged Islamic banks and standalone Islamic Branches of nine conventional banks in Pakistan. The study employed annual unbalanced panel data spanning from 2004 to 2018. In the light of findings obtained from Im, Pesaran and Shin panel unit root test, Breusch-Pagan LM test, and Hausman test, Random Effect (R.E) estimation technique was employed. The results showed that Islamic bank specific variables as well as macroeconomic variables had significant impact on economic growth in Pakistan. The study concluded and recommended that Shariah compliant financing has great potential to boost up the economic growth of Pakistan and to achieve other SDGs in Pakistan as well, if government of Pakistan takes solid steps to promote Shariah compliant financing.

Abstract
This study aims to analyze the role of agricultural contextual knowledge on the mathematical understanding of vocational students. The study used a qualitative approach to vocational students in food crop and horticulture agribusiness competencies in Ciamis, Indonesia. Students solve the mathematical tasks in agricultural situations integrated with three-dimensional topics. The results obtained are: (1) students contextual knowledge of agriculture affects the understanding of the context or situation of the task; (2) some students who have agricultural contextual knowledge tend not to integrate the context of task problems and mathematical concepts; (3) students who have contextual knowledge, coherence and correspondence all information, connections with mathematical concepts tend to be able to complete tasks. These results indicate that contextual knowledge of agriculture can provide a role in mathematical understanding or not depend on the problem of the task and the ability of students in the coherence and correspondence of information, as well as mathematical connections.

Abstract
One of the products of plantations in Indonesia is cashew. Cashew has a very high vitamin C content. However, this fruit is easily damaged and the price is relatively low, so it is necessary to innovate in processing this fruit, one of which is to be made into cashew ice cream. This study aims to determine the effect of the proportion of whipped cream and the proportion of emulsifiers / SP on vitamin C content, physical quality (overrun & melt speed) and the favorite value (hedonic) of cashew ice cream (Anacardium occidentale L). This study used a completely randomized design method (CRD) with double sample replications and two test replications. For panelists on hedonic testing using 20 semi-trained panelists. The results showed that the proportion of whipped cream and cashew with an emulsifier / SP proportion had a significant effect (p <0.05) on overrun, melting speed, vitamin C level. The proportion of whipped cream had a significant effect (p <0.05) on the hedonic test ( taste and aroma) but the proportion of emulsifier / SP has no significant effect and hedonic test which includes the color of the aroma and texture. The best treatment is the proportion of 200 g cashew, whipped cream 400 g and emulsifier / SP 15 g with HPP (cost of production) of Rp. 851.5 and the selling price of Rp. 1,200 with a 30% profit.
