While compiling the author's dictionary, he saw many Arabic and Persian sources and made quotations from them. While witnessing the articles, he sometimes gave their Arabic and Persian equivalents, making statements that they were idioms or trophies. In this study, information about lexicography, the oldest dictionaries and their spelling purposes was given under the title of "An Overview of Persian Dictionary Writing". In the "Idiom Dictionaries" section, important idiom dictionaries written in Anatolia, Iran and Arabian fields are emphasized. Immediately afterwards, information was given about the life and works of the author. Detailed information about Majma al Amsal is given in this section. Within the scope of these evaluations, we aimed to reveal Khalis Ebrahim Afandi's lexicography and his understanding of lexicography. In the last part, the text was presented by applying the translation-writing system and arranging the Arabic-Persian parts in Arabic letters. This study will provide great support as a reference source to those who work or will work in all fields of social sciences, especially Turkish and Persian language and literatures
The Christian Right and US Foreign Policy in the Twenty-first Century
Full text linkThe thesis discusses the role of the Christian Right in the US foreign policy decision making process. The research revealed that the Christian Right has long been fascinated with some international issues in general and US foreign policy in particular. The Christian Right’s interest in international issues increased markedly during years of the George W. Bush presidency. It successfully widened its activities from domestic social conservative issues to foreign policy issues by participating in, articulating and lobbying for its religious version of American foreign policy. In assessing the role of the Christian Right in US foreign policy making, this dissertation examines three aspects of US foreign policy, namely Israel, international religious freedom and global humanitarianism. Based on these aspects, the Christian Right is seen as skilled in framing and defining issues. The Christian Right seems effective in selecting and prioritizing international issues that have a reasonable chance of being selected by foreign policy decision makers, especially in Congress. Moreover, the Christian Right has shown its maturity in seeking engagement and cooperation with other organizations, secular and religious, in order to advance its international goals. Finally, in pursuing and conveying its international agenda, the Christian Right has adopted a more moderate and less overtly religious approach. Instead of using its traditional religious rhetoric, the Christian Right has successfully projected its foreign policy preferences into the conventional realist discourse of American foreign policy that is largely based on the objective of national interest and national security. Nevertheless, this study does not, in any way, conclude that the Christian Right was able to influence or determine the direction of US foreign policy and its outcomes; however, it does suggest that the Christian Right did contribute and have an impact on the formulation of some US foreign policy. As such, the research contends that the role of the Christian Right is similar to other interest group lobbies and that its perceived influence on US foreign policy should not be exaggerated. Finally, the research suggests that the emergence of the Christian Right as an actor in asserting its global agenda through US foreign policy can possibly provide an example of how religious beliefs and values can become a potential source of “soft power”. Together with the “climate of opinion” of the American public during the Bush administration, the “soft power” at domestic level could serve as a valuable new explanatory variable in understanding how the US foreign policy was formulated in the early 21st century
Evaluasi Kebijakan Harga Dasar Gabah: Studi Kasus Panen Raya Tahun 2000
No full textGovernment gave its support to a price policy with a gabah floor price that was expected to stimulate rice pro-duction. But, during the 'great harvest' 2000, the gabah price fell below the floor price in many paddy production centre. The result'of this research concluded that the gabah floor price is too low. Above all, the goveinment was not pick-aback and implementing the floor price policy seriously. It's prove that 'cheap food policy', the policy which consumer oriented, is continuing. If this "position" not to be changed, it is potentially provoke the paddy farmer not to produce rice more. Then, the food security can be worst at the next time. Because of the serious implication would be happen, the author recommend to push-up, as an adjust-ment, the level of gabah floor price, and then it must be guarranteed (by the government) as an urgen agenda

PEMBELAJARAN SEJARAH THINKING LIKE A HISTORIAN: CRITICAL READING, MIND-MAP, DAN CREATIVE WRITING
Full text linkLEARNING HISTORY THINKING LIKE A HISTORIAN: CRITICAL READING, MIND-MAP, AND CREATIVE WRITINGThe study of history should not rely on only one source or one authoritative narrative. The nature of history which necessitates a postulate that once a historical event is written, it immediately becomes something subjective. It is certain that a written historical event is absolutely influenced by the subjectivity of the author. Therefore, history learning does not require a single narrative. History learning must provide opportunities for students to practice historical thinking skills that contain sensitivity to the multiple causes of events, empathy toward an event investigated, and sensitivity to change and continuity. This article attempts to offer a history learning model that facilitates students to master historical thinking skills by using activities such as critical reading, mind-map making, and creative writing.Pembelajaran sejarah tidak seharusnya hanya mengandalkan satu sumber atau satu narasi yang dianggap otoritatif. Sifat dasar sejarah yang meniscayakan adanya ketetapan bahwa ketika suatu peristiwa sejarah ditulis, maka seketika itu pula menjadi sesuatu yang subjektif, karena dipastikan penulisan peristiwa sejarah tersebut sedikit-banyak dipengaruhi oleh subjektivitas penulisnya, itu tidak menghendaki adanya narasi tunggal. Oleh karena itu, pembelajaran sejarah harus disertai dengan upaya untuk menghadirkan kesempatan bagi peserta didik untuk melatih kemampuan berpikir kesejarahan yang mengandung sensitivitas terhadap multi penyebab dari suatu peristiwa, empati terhadap konteks peristiwa yang sedang dikaji, sensitivitas terhadap perubahan, dan keberlanjutan. Artikel ini mencoba untuk menawarkan model pembelajaran sejarah yang memfasilitasi peserta didik untuk menguasai kemampuan berpikir kesejarahan dengan memakai kegiatan seperti critical reading, pembuatan mind-map, dan creative writing
The Study of Flow Dynamics in Long Pipeline for the Transport of Carbon Dioxide (CO2)
Full text linkCarbon dioxide (CO2) capture and storage (CCS) is usually considered as a chain consisting three separate elements; capture, transport and storage of the CO2. The capture and the storage are the two most studied parts of the CCS chain; however, the transport also gives the important roles in this system. For this study, the title of the project is to study the dynamics of the flow in the long pipeline for the transport of CO2.
The dynamics flow of the CO2 transport in a long pipeline was studied and analyzed. At first, before the study is carried out, the author thinks of the uncertainties that will arise in the transport of CO2. Some of the uncertainties that might occur are the effect of the flow, the pressure drop and the changes of the temperature but for this research, the author will do the study of the effect of the flow and the changes in the velocity and the pressure in long pipeline of the CO2 transport.
For the completion of this study, the author used two main methods which is using the research methodology and construction of the pipeline model using the Computational Fluid Dynamics (CFD) software. The research is carried out for the project’s concept understanding. The research had been done by reading the technical articles, and the previous related research from various author. Later the model is constructed using the CFD software.
As expected, for a very long and open ended pipeline, the pressure will drop as the length of the pipeline increases. Besides that the bending angle of the pipe also give impact to the flow of the CO2; the greater the bending angle of the pipeline, the higher the CO2 flow pressure will loss. In addition, in the bending pipeline, there will be a back flow occurred to the CO2 flo
