...Sustainability of BMT financing for Developing Micro-enterprises Widiyanto b. Mislan Cokro1 Abdul Ghafar b. Ismail2 School School of Economics Universiti Kebangsaan Malaysia Bangi, 43600 Selangor D.E., Malaysia E-mail : This draft, February 2008 Abstract The aim of this study is to analyze the sustainability of Islamic micro-financing for developing micro-enterprises (ME). We use the sample of Baitul Mal Wat Tamwil (BMT), as Islamic microfinance institution in Indonesia. Two approaches will be used to explore the sustainability, i.e., technical efficiency (using data envelopment analysis (DEA) and level of outreach. The results indicate that: first, generally the efficiency of BMTs is relatively low. Scale efficiency also indicates that BMTs are operated still far from optimal scale. The results suggest that there is gap in efficiency scores obtained from CCR and BCC models. This indicates that BMTs still face the managerial problems. Second, Islamic micro-financing is useful for developing micro-enterprises and contribute a great social benefits to the society in several ways. Although the profitability efficiency of BMTs is relatively low, since generally BMTs have made a profit and social benefit, Islamic financing can be predicted to be sustainable – able to provide viable Islamic financing. Keywords: Sustainability, technical efficiency of profitability efficiency, level of outreach. 1 Lecturer of Islamic economics, Sultan Agung Islamic......

Micro Finance

...provides small loans to some of the poorest communities in underdeveloped countries all over the world. The ultimate goal of microfinancing is to help the poor pull themselves out of poverty. In America, people typically use loan money to increase their assets. These assets could consist of a starting a business or making an investment with the expectation of gaining a return; they do not typically use the money to purchase the basic necessities of life. However, in underdeveloped countries, residents take out loans through the concept of microfinancing to get through their everyday life. My thesis states that there is a common misconception that Microfinancing Institutions (MFIs) only loan money to poor people in order for them to start a micro enterprise (also known as a small business). With this misconception, people do not acknowledge the fact that they live a significantly different lifestyle than those in underdeveloped countries. In this paper, I argue that despite the lack of increased income that an investment may bring, (to someone in a developed country), microfinance is very beneficial to the poor by providing the ability to maintain financial stability. MFI’s are beneficial to those in underdeveloped countries in three ways: maintaining basic needs, paying for health and family emergencies, and empowering women. A major problem in understanding the financial impact of these MFIs is that the ‘benefits’ are extremely difficult to measure. The problem may lie......

...EXPERIMENTAL STUDY OF MICRO ULTRASONIC MACHINING PROCESS Sreenidhi Cherku, Murali M Sundaram, and K P Rajurkar Center for Nontraditional Manufacturing Research University of Nebraska-Lincoln Lincoln, Nebraska, USA INTRODUCTION Micro ultrasonic machining (micro USM), is one of the efficient material removal processes especially suitable for the micromachining of hard and brittle materials. The principle of micro USM is shown in Figure 1. In micro USM workpiece which is placed on the workpiece table vibrates at ultrasonic frequency (40 KHz). Abrasive slurry is injected on the top of the workpiece. There is a rotating tool which hits the abrasive particles in the slurry which in turn hit the workpiece and chip away the material from it. The vibrations given to the workpiece aid in refreshing the slurry so that fresh abrasive particles are in contact with the workpiece and also in removing the debris from the tool workpiece gap [1-4]. In many conventional machining processes like grinding, milling and broaching processes oil has been successfully used as cutting fluid. These oils can be used either as straight oils, which are pure petroleum based oils or emulsifiers which are water based oils. Use of straight oils have excellent lubricating properties and are used especially for machining process involving low speeds, low clearance requiring high quality surface finish. These oils have more viscosity and good lubricating properties than......

...them. As a result, they face the problem of class control throughout the lesson. It is hypothetical that one of the best techniques to help teacher trainees develop their skills is to use ‘micro teaching’ as a technique of training. But, in the process of training of teachers of national colleges of education enough weight is not given to micro teaching. Microteaching is organized practice teaching. The goal is to give instructors confidence, support, and feedback by letting them try out among friends and colleagues a short slice of what they plan to do with their students. Ideally, microteaching sessions take place before the first day of class, and are videotaped for review individually with an experienced teaching consultant. Microteaching is a quick, efficient, proven, and fun way to help teachers get off to a strong start. (Harvard University) As mentioned above micro teaching is a method that helps teacher trainees use their techniques in the same environment where they are given practice and among their critical friends. American heritage dictionary further explains micro teaching as a method in which one small section of a lesson conducted by a student teacher is first videotaped and later viewed by the others for evaluation. (www. Hence it is evident that micro teaching can be used to improve the performance of teacher trainees with the help of their peers....

...villages. Hence, it is easier to form groups that would follow a standardized procedure. This makes it easier to operate with the Grameen system in Bangladesh than in India. It is observed that the Grameen system is better suited for more densely populated areas. There are parts of India which are as densely populated as Bangladesh, and some of the Northern hill tracts, and some part of the Sundarbans, are fairly thinly populated. The population density in India is a little higher than 1/3rd that of Bangladesh. In the Grameen system, the groups avail micro-financial services from the Bank, while the SHGs are effectively a microbank carrying out their own savings mobilization and lending. The basic difference in the approaches of the Grameen system and the SHG model is that the former starts with microcredit and then graduates to micro-savings, while the SHG model is based on the concept of micro-savings leading to micro-credit. Thus, the SHG model is more sustainable from viability point of view. Though both the models are for the poor, yet Grameen system is more suited to the very poor category of people who may not have sufficient fund to generate the initial savings required in the SGH system. Unlike Bangladesh, India has a good network of commercial banks with almost 70% of the 80,000-odd bank branches located in the rural and semi-urban areas.

...only to the sectoral equity caps, entry routes and other relevant sectoral regulations. The issue of de-reservation had been a subject of animated debate within government for more than twenty years. The Approach to the Eleventh Five Year Plan noted the adverse implications of reservation of products for exclusive manufacture by the MSEs and recommended the policy of progressive de-reservation. To facilitate further investments for technological up-gradation and higher productivity in the micro and small enterprises, 654 items have been taken off the list of items reserved for exclusive manufacture by the manufacturing micro and small enterprises in the last few years – reducing it to 21 at present. This has helped the sector in enlarging the scale of operations and also paved the way for entry of larger enterprises in the manufacture of these products in keeping with the global standards. Credit/Finance Credit is one of the critical inputs for the promotion and development of the micro and small enterprises. Some of the features of existing credit policy for the MSEs are: Priority Sector Lending: Credit to the MSEs is part of the Priority Sector Lending Policy of the banks. For the public and private sector banks, 40% of the net bank credit (NBC) is earmarked for the Priority Sector. For the foreign banks, however, 32% of the NBC is earmarked for the Priority Sector, of which 10% is earmarked for the MSE sector. Any shortfall in such lending by the foreign banks has to......
