Abstract

Having very small coefficient of seepage, wide clog, , soil bearing capacity is very low., create the complexity of clay. The pole foundation is what frequently used in clay. Mostly the hard layer of clay soil is far lying under ground along with the rare use of hexagonal foundation which had widely been circular and rectangular. Minimizing the pole in pile group is one of the alternatives to reduce the construction budget. By comparing the pole circle-basis, rectangular, and hexagonal section with variation of dimension 0.3; 0.35; 0.4m, an investigation to the number of pole in pile group based on SPT for vertical soil bearing capacity as well as lateral Brooms method at each cross-sectional shape of the pole is carried out. The results obtained shows similar diameter which finds the number of poles at least up to the highest, in the pile group is a consecutive sequence of rectangular cross-sectional shape of the first, second is a circle, and the third is a hexagon. The percentage of number of rectangular pole   78% from circular and 73% from hexagonal shape.

Abstract

Non-Performing Financing (NPF) is the inability of customers to meet their obligations in accordance with the contract, which can be categorized into three types namely substandard, doubtful and bad debt (macet). NPF is the main and biggest risk for sharia banks, hence the ability of sharia banks to identify, measure, monitor and control the risks of financing and capital provision is very important. Sharia banks will face greater risks than conventional banks because of the risk of sharia reputation. Besides being influenced by internal and external factors of sharia banks, NPF can also be influenced by the financing contract (akad) used.This study analyzes the level of financing risk based on the contract. The population and sample are all Sharia Rural Banks in Indonesia with 167 secondary data in the form of the publication of financial statements for 2011-2018. Analysis of the data using quantitative descriptive methods with a survey approach.

Abstract

Sharia industry development encourages experts to design Corporate Social Responsibility (CSR) disclosure index that is more compatible with the characteristics of sharia-based corporate. However, studies examining CSR disclosure using Islamic Social Reporting (ISR) index that focuses on detailed results of content analysis from time to time still remains a paucity of evidence. Hence, this study aims to examine the practice of Islamic Social Reporting disclosure of sharia commercial banks in Indonesia. Drawing on the data obtained from CSR reports established by sharia banks in Indonesia, the results of content analysis disclosed that the ISR disclosure showed a fluctuating trend. It was also revealed that the six themes of ISR index have not been optimally disclosed. ISR disclosures of sharia banks in Indonesia were categorized as good since the average disclosure reached 50% in 2015 up to 2017, especially the corporate governance disclosure. This study’s results imply that it is necessary to increase the disclosures that can be strengthened by regulations from financial regulators and Islamic banking associations to increase public trust and value-added of sharia commercial banks. This study contributes to the development of sharia banks as fruitful insights on policy recommendations for Islamic banks' top management.

Abstract

Sharia compliance is the adherence of Islamic banks to Islamic rules or laws in muamalah and is one of the factors that differentiate it from conventional banks. Therefore sharia compliance is a fundamental principle in Islamic banking practices. Muamalah law, especially the economy, has a high degree of difference, so the sharia compliance standards in Indonesia refer to the Fatwa of the National Sharia Council-Indonesian Ulama Council (DSN-MUI). This study aims to analyze the practice of sharia compliance in Islamic Rural Banks (BPRS) in Indonesia. The data analyzed is the assessment of the Sharia Supervisory Board (DPS) on the practice of BPRS for five years. The sample distribution covers all regions of Indonesia with 24 units of analysi with 46 respondenss. The data analysis used quantitative descriptive analysis and compared it with the DSN-MUI fatwa. This study's results indicate that the level of compliance with Islamic rural banks in Indonesia is, on average, excellent. Other findings show that, when viewed from the contract's practice, financing with a musyarakah contract has the highest level of sharia compliance compared to separate agreements. Meanwhile, the lowest sharia compliance is in the murabahah contract. This condition is influenced because Islamic banks often use the murabahah bil wakalah contract. The weakness of this contract lies in the procurement of goods by customers, often not accompanied by proof of purchase.
