Abstract

Data security is very important data needed to stay awake in strict confidence from hacker intrusion or criminals who want to steal the data. Data security methods that are used in this paper is a digital image encryption by using a modified Hill’s code which is done by changing the way of encryption. If we are using Hill’s code then matrix pixel multiplied is the key matrix while on the modification Hill’s code before the key matrix then the matrix is multiplied pixels must be added to the results of the main diagonal elements of the matrix times key. The results obtained in the process of digital image encoding indicating that the image is encoded with password modification results of modified Hill's code more mixed reviews when compared to the image that was encoded with password Hill so that more effective in securing data in the form of a digital image. The size of the image file using the encoding results in a modification password Hill is smaller than ordinary password Hill with a percentage decrease of 4.6 % so more ease in delivery through electronic media Keyword: Digital image, modified Hill code, encryption, description

Abstract

Kajian tentang pesantren telah banyak dilakukan oleh paraahli, dalam dan luar negeri dengan beragam pendekatan, namunsering menghasilkan kesimpulan yang tidak konsisten dankarenanya tidak memuaskan. Tulisan ini berusaha mendeskripsikaneksistensi pesantren yang telah berlangsung selama enam abadsekaligus menjadi satu-satunya institusi pendidikan milikmasyarakat pribumi yang menjadi ujung tombak pembangunanperadaban Melayu Nusantara sekaligus telah memberikankontribusi sangat besar dalam membentuk masyarakat melek hurufdan melek budaya. Dinyatakan pula, dengan eksistensinya yangsemakin bertahan dan memperoleh pengakuan serta variasinyayang semakin beragam telah mengantarkan pada kesimpulanpesantren memiliki karakter plural, beragam dan tidak uniform.

Abstract

Islamic boarding schools are religious institutions that not only teach religious problems to santri, but also relate to the role of porndok pesantren on community empowerment. Islamic boarding schools also have a role in national politics. In this context the role of the pesantren in dialogue and contextualizing Islamic teachings is not rigid and black and white. But Islamic boarding schools are able to display the teachings of Islam that are harmonious, peaceful, tolerant, and not radical. Islamic understanding initiated by Islamic boarding schools is far from the values of radical doctrines, or easy doctrine to state ‘heresy’ to other groups. This becomes the view and value championed by the pesantren community including the role of the Kiai (Islamic clergy) in developing modern and global life.

Abstract

A soil water retention curve determination method is developed based on the use of gipsblock and capacitance sensors. The objective of the research was to provide a simple and quick method in characterization of soil water retention in the laboratory based on resistance and capacitance sensors. Undisturbed soil sample collected using stainless steel ring sampler 8cm in diameter and 6cm height. Digital gipsblock and capacitance sensors connected to personal computer detected periodically water tension and volumetric water content of the sample. To test the reliability of collected data, measurement using pressure plate apparatus was also conducted. Result of the experiment for soil samples textural classes loam to clay loam leaded well compromise with result from pressure plate. However, significant deviation of soil water content has been detected as the  soil water suction exceeded 15,000hPa. Deviation of measured water content increased with the reducing water content up to 0.300cm3.cm-3. Implication of this result showed a further finer standardization assesing water tension above 10.000hPa is needed.

Abstract

This article explores moderate and eclectic traditionalism beyond Kiai Haji Muhammad Hashim Ash’ari’s contribution in the shariah and Islamic jurisprudence of social politic (Fiqh al-Siyâsah al-Ijtimâ’iyah) in Indonesia. It is conceptual research referring to some of his works as well as discussion about his thought among Islamic scholars. Based on definition of moderation from the Qur’an, hadith, and some scholars’ opinion, Hashim can be best categorized as Islamic traditionalist figure who enforced both moderation and eclecticism. However, he maintained distinctive features compared to both traditionalist and modernist Islamic figures. It is mainly clear from both his thought and movement which rely on the Ahlus Sunnah wal Jama’ah in theology, four fiqh school leaders (Hanafiyah, Malikiyah, Syafi’iyah dan Hambaliyah), and thariqah sufiyah mu’tabarah. Additionally, he showed appreciation and promoted for adaptation to both local and foreign idea that later inspired distinctive religiosity in Indonesia. This particularly applies in the concept of relation between Islamic law and nationalism, jihad, political fiqh and governmental system in Islam. تستكشف هذه الورقة الوسطية التقليدية والانتقائية التي ساهمها كياهي حاجي محمد هاشم الأشعري في الشريعة الإسلامية وفقه السياسة الاجتماعية. إنه بحث مفاهيمي يشير إلى بعض أعماله وكذلك مناقشة حول أفكاره كعلماء المسلمين. بناءً على تعريف الوسطية من القرآن والحديث وبعض آراء العلماء، يمكن تصنيف هاشم بشكل أفضل على أنه الشخصية الإسلامية التقليدية التي فرضت الوسطية والانتقائية. ومع ذلك، فقد حافظ على سمات مميزة مقارنة بكل من الشخصيات الإسلامية التقليدية والحداثية. يتضح بشكل أساسي من فكره وحركته اللذين يعتمدان على أهل السنة والجماعة في العقيدة، قادة المذاهب الفقهية الأربعة (حنفية، المالكية، الشافعية والحبلية) والطريقة الصوفية المعتبرة. بالإضافة إلى ذلك، أظهر التقدير والترويج للتكيف مع الأفكار المحلية والأجنبية التي ألهمت لاحقًا التدين المميز في إندونيسيا. وهذا ينطبق بشكل خاص على مفهوم العلاقة بين الشريعة الإسلامية والوطنية والجهاد وفقه السياسية والنظام الحكومي في الإسلام.
