ممارسات متنوعة في قياس عامل الإنتاجية الكلية للعراق: دراسة تحليلية للمدة (1970-2017)

The index of the total productivity factor is one of the most important measures expressing the efficiency of resource use, and an important indicator of technological development among the countries of the world. His great contribution to economic growth reveals his ability to lead economic growth. The strong negative changes taking place in the total factor productivity of the country confirm a series of successive events such as the decline in economic growth (negative growth), for example the decline in total productivity during the Great Depression of 1929, and the slowdown in total productivity in the United States of America in the seventies. On the other hand, achieving distinct real economic growth means improved efficiency and performance and a clear rise in the efficiency of resource utilization accompanied by a distinctive technological development for the country concerned, as has happened in China for the past two decades. It was revealed to us by measuring the growth in the total productivity factor of Iraq in the long term, and after using five diverse productivity functions through which (calculating economic growth) was applied, and using three methods (formulas) for each of the five functions and they are; (Solo remainder, regression, and Ferguson's dummy variable method for instability), we have fifteen time series of TFP growth. It has become clear that the calculation of the total productivity factor suffers from a (technological illusion), and there is no technological development in Iraq for the period (1979-2003), at the very least, as "it became clear to us that there is a clear weakness in the contribution of the factor of total productivity to economic growth," and it became clear that the efficiency of resource utilization did not rise to the level of ambition, and the reason is mainly due to political instability, accompanied by the misuse and distribution of resources, which contributed to the deterioration of the economic and social conditions of Iraq specifically during the period (1980-2017). It was also found that the dummy variable of political instability has taken many forms and continuously influencing, was reflected in the fluctuation of growth values in the factor of total productivity calculated by methods and formulas, totaling fifteen practices of the total production function. The successive political events with their diversity were a concomitant characteristic and negatively affecting the Iraqi economic growth during the mentioned period.

Total Productive Maintenance and its Effecting on the Application of Lean Production System

Increasing the amount of production, the diversity of products, a commodity and / or service, and increasing the productivity factor ratios contribute to developing the competitive strength of the organization in light of the increasingly difficult market conditions. That made all organizations work according to competitive strategies, including the production strategy for the purpose of achieving the organizations goal through the set of goals that they put. They rely on several new management systems of a strategic nature aimed at their survival and continuity in the production market. Hence, this research aims to evaluate the total productivity maintenance capacity in lean production throughout reducing the various kinds of losses, as the lean production is based on reducing each defective product (a commodity and / or service), costs, errors, and area, and all that and others aimed at improving product quality and customer satisfaction. However, the overall goals and production programs often encounter unexpected breakdowns at unexpected times, which lead to a breakdown in production and an imbalance in production plans as a result. Consequently, the companies suffer the expected revenue loss because they fail to reach the targeted production amount. The research has adopted a questionnaire that has been distributed to (50) employees of the General Company for Electric Power Production, the central region in Baghdad, which constituted more than 10% of the company’s employees. The results show that there is a strong direct relationship between the independent variable (total productivity maintenance) and the dependent variable (lean production). This distinction has explained 90% of the variables in the dependent variable.

Rapid Truck Loading for Efficient Feedstock Logistics

A multi-bale handling unit offers an advantage for the efficient hauling of round bales. Two empty racks on trailers are left at a satellite storage location for loading while a truck tractor delivers two loaded racks to the biorefinery, thus uncoupling the loading and hauling operations and increasing the efficiency of both. The projected 10 min trailer exchange time equals the projected 10 min unload time at the biorefinery achieved by lifting off the two full racks and replacing them with two empties, a technology adapted from the container shipping industry. A concept is presented for a bale loader that latches onto the rack/trailer and loads bales into the bottom tier chambers. This machine will load 10 bales into the rack on the front trailer by attaching on to the front of the trailer and 10 bales into the rear trailer by attaching onto the rear. A telehandler removes bales from single-layer storage and places them in the bale loader to load the bottom tier compartments. The top tier compartments are loaded directly from the top. Expectations are that an experienced operator can average 9 loads in a 10 h workday, and load-out cost is estimated as 3.61 USD/Mg, assuming the average achieved load-out productivity over annual operation is 60% of optimum productivity (24 Mg/h) equal to 14.4 Mg/h. Cost increases to 4.81 USD/Mg when the productivity factor drops to 45%, and cost is 3.09 USD/Mg for a factor of 70%.

Dimensi Ekonomi Produktif dalam Regulasi Wakaf di Indonesia

<p><em>Waqf is a form of worship in Islam which has productive economic value. And Law no. 41 of 2004 concerning Waqf has opportunities for economic development for the benefit of social welfare. For this reason, it is necessary to have a study that analyzes the Waqf Law from a productive economy perspective. In this study, using content analysis method, which is an in-depth discussion of the content of written or printed information. In this case Law No.41 of 2014 concerning Waqf seeks to be coherent with productive economic theory. And the theory used as an analysis tool is the productive economic theory of Qutub Abdul Salam, in terms of the dimensions of productive economic goals and the main factors needed. Thus, this research actually aims to find the coherence of the articles in the Waqf Law with the Productive Economic Theory developed by Qutub Abdul Salam. From the results of data collection and analysis, it can be concluded that the Waqf Law is kohern with productive economic theory. The purpose of productive economic activities is to increase the benefit that can be realized in various forms, including: Meeting human needs at a moderate level, finding community needs and their fulfillment, providing supplies of goods / services in the future and fulfilling the means for social activities and worship of Allah. Among the articles in the Waqf Law which are coherent with productive economic objectives is article 5 of the Waqf Law, which explains that waqf functions to realize the economic potential and benefits of waqf assets for the benefit of worship and to promote public welfare. In productive economic theory, the productivity factors of a business include four things: natural resources, managers / workers, skills and capital. The natural resource factor as one of the factors in the development of the productive economy is coherent with the Waqf Law, namely waqf objects in the form of land, buildings or other immovable objects. The productivity factor in the form of managers or workers managing and carrying out waqf assets is nazir which includes; individual, organization, or legal entity. Skill is a very important productivity factor in managing waqf assets. Nazir as the manager of the waqf will receive guidance from the Minister of Religion and the Indonesian Waqf Board (BWI) both in terms of skills and managerial. And the capital factor in the context of the management of waqf assets is the object of waqf. In the Law on Waqf the objects of waqf include movable and immovable objects. With the issuance of the Waqf Law No. 41 of 2014, immovable objects have become important assets in the development of productive waqf. Movable property that cannot be used up due to consumption includes: money, precious metals, securities, vehicles, intellectual property rights, lease rights and other movable objects in accordance with the provisions of sharia and applicable laws and regulations.</em><strong><em></em></strong></p>

Emergy-Based Evaluation of Changes in Agrochemical Residues on the Qinghai–Tibet Plateau, China

Study of changes in agrochemical residues on the Qinghai–Tibet Plateau is necessary for the agricultural green development of the fragile plateau and its downstream regions. The total agrochemical residue (TR) caused by main agrochemical inputs was estimated in the study area of Qinghai province and the Tibet Autonomous Region over 1995–2017 by using the emergy synthesis method. The total agrochemical residue was decomposed into the intensity factor, the structure factor, the productivity factor, and the labour factor by using the Logarithmic Mean Divisia Index (LMDI) decomposition method. The change in TR could be divided into four time periods, i.e., a rapidly increasing period during 1995–1998, a stable period during 1999–2004, a slowly increasing period during 2005–2011, and a fluctuant period during 2012–2017. The study area had a mean TR intensity in area (TRA) of 3.31 × 1014 sej/ha, which was only 38.21% of that in China; however, the annual growth rate of TRA in the study area was 2.93%, higher than the rate of 1.91% in China over 1995–2017. The study area had a mean TR intensity in production (TRP) of 4.06 × 1010 sej/CNY (Chinese Yuan), which was 71.05% of that in China; however, the annual decreasing rate of TRP in the study area was 0.95%, lower than the rate of 1.98% in China over 1995–2017. All the LMDI decomposed factors contributed to the TR increase during 1995–1998; the intensity factor, the structure factor, and the labour factor contributed to the TR decrease during 1999–2004; the structure factor and the productivity factor contributed to the TR increase during 2005–2011; and only the productivity factor contributed to the TR increase during 2012–2017. Compared with the whole country, the study area has more potential to reduce TR by improving agrochemical use efficiency, strengthening the recovery of plastic film residue, increasing organic agricultural materials, raising the efficiency of agricultural production, and accelerating the transfer of rural labours to secondary and tertiary industries.

FACTORS AFFECTING THE ECONOMIC POLICY OF FOOD IN INDONESIA

Food security is one indicator of economic growth of a country and may reflect the prosperity as well as a benchmark of the the welfare level, particularly in terms of people’s production and consumption. Food security policies need to be supported through increased production of commodities. Corn is one crop with a strategic role due to its position as the main source of carbohydrates and protein. To increase the production of corn, there should be the policy inputs or factors of production done by increasing the planting area and the productivity of corn crops in Indonesia. This study aims to analyze the factors of production that can increase the production of corn farming. The data used are time series data with Nerlove model as the data analysis way. The results indicate that the harvest area factor and productivity factor may influence the increasing of farm production of corn; it thus can serve as the basis of economic policy-making related to the food sector in Indonesia.
