Abstract

Sistem pengenalan sidik jari bertujuan untuk mengidentifikasi sidik jari seseorang sehingga dapat di kenali ciri unik dari orang tersebut. Hasil dari ekstraksi ciri sidik jari sangat bergantung pada kualitas dari citra sidik jari itu sendiri, seperti halnya kejelasan ridge structure pada citra sidik jari. Citra yang baik akan memiliki kontras yang baik dan dapat menggambarkan ridges dan valleys. Jenis sidik jari didefinisikan diantaranya: sidik jari berminyak yang memiliki piksel ridges cenderung sangat tebal, sidik jari kering yang memiliki ridges yang kasar pada tingkat lokal dan terdapat piksel putih/ valley yang banyak, serta sidik jari netral secara umum tidak memiliki sifat khusus seperti berminyak dan kering. Untuk mendapatkan citra yang baik pada citra sidik jari kering dilakukan ekstraksi garis tengahnya dan menghapus piksel putih/valley sehingga nilai ridge meningkat. Penelitian ini menggunakan metode FFT karena FFT merupakan salah satu algoritma yang dapat menghitung secara cepat dan mendukung dilakukan proses secara real time. Dengan metode FFT citra sidik jari dengan ridges yang terputus dianalisa dan dihitung probabilitasnya dari ridge frequency dan ridge orientation, setelah ditingkatkan kualitasnya dengan menggunakan FFT maka didapatkan peningkatan piksel ridge 97.52 % pada konstanta k=0,6. Dan Hasil Verifikasi Persentase Matching Sidik jari tertinggi pada nilai konstanta k=0,6 yaitu 54,29%.

Abstract

Abstract: The Period of  Abbasid rule was also called the golden age of Islam. It was so called since in that period, some Muslim scholars in the field of Islamic law and philosophy emerged. The emergence of Muslim scholars at that time was closely related to the obligation to search knowledge in Islam and the supports of the caliphs.  It is because of the obligation that a translation institution called Bait  al-Ḥikmah was established. In this institution, the Greek works were translated into Arabic. The translation works were then  completed   with new thoughts of the translators and spread out to Syria, Spain and Cecilia. It was the dominant basis for the development of science in the West  since the beginning of  the Renaissance era.     Kata Kunci: Bait  al-Ḥikmah, tradisi keilmuan Islam, era Abbasiyah

Abstract

The term ‘light’ in Sufism has become a favourite terminology in different cases. It has been one of central themes in the work of ‘sufi’. Al-Ghazālī proved his excellence when he interpreted the verses on light. The terms in those verses are interpreted as inner strengths of human such as senses, rationale, imagination, thinking, and intuition. These are lights by which the Almighty God leads human beings to get the fundamental light. This can, of course, be achieved by maximising human potentials through education.

Abstract

Abstract:This study aimed to describe the view of al-Ghazali about how to view and interpret the text. The focus of the study was directed to the nature behind the term, examples of Sufi interpretation, and pedagogical reflection. The writer examined the text contained in Ihya Ulum al-Din and Misykat book. The results showed that al-Ghazali recommended to not just focus and stop at the term, but it also should explore the deepest meaning without ignoring the meaning of the term as a benchmark and a starting point. Sufi esoteric interpretations of the water in the QS 13/17 is marifat, valleys mean the human heart, and spring called the Quran primordial. In the perspective of education, educators need to teach students not only the textual meanings of a text, but also the truth (philosophy) behind it.Abstrak:Kajian ini bertujuan untuk memaparkan pandangan al-Ghazali tentang cara melihat dan memaknai teks. Fokus kajian diarahkan pada hakikat di balik istilah, contoh tafsir sufistik, dan diakhiri dengan refleksi paedagogis. Penulis menelaah teks yang terdapat dalam kitab Ihya Ulum al-Din dan kitab Misykat. Hasil kajian menunjukkan bahwa al-Ghazali menganjurkan untuk tidak hanya terpaku dan berhenti pada istilah, tetapi lebih dari itu harus menyelami makna terdalamnya tanpa mengabaikan makna istilah sebagai patokan dan titik berangkat. Tafsiran sufistik esoterik tentang air dalam QS 13/17 ialah ma’rifat, lembah-lembah berarti kalbu manusia, dan mata air disebut dengan Al-qur’an primordial. Dalam pers-pektif pendidikan, seorang pendidik perlu mengajarkan kepada peserta didik bu-kan hanya makna lahiriah dari suatu teks, melainkan juga hakikat di balik makna lahiriah tersebut.

Abstract

With a range of long distances or depths and areas beyond the reach of the internet it is necessary to design a wireless SCADA system based on the AX.25 protocol for the purpose of monitoring Micro hydro power generation and forming a prototype in a model of a micro hydro power plants (Micro hydro power plant) wirelessly monitoring system. The method used in this research is quantitative method, by designing a system to monitor Micro hydro power plant wirelessly by utilizing AX.25 protocol. This system can monitor several Micro hydro power plant parameters such as voltage, current and frequency and turbine rotation so that it can be accessed directly at one central location. Data transmitted by Remote Terminal Units (RTUs) may serve as a reference for operators to decide on further steps if any monitored Micro hydro power plant parameters change from a predetermined standard. This prototype has been simulated using the Proteus 8.6 and LabView 2012 software. Data from the sensors transmitted over radio frequency using KYL 1020 from each RTU to MTU and connected to the computer using LabView software and displayed on the computer with taking into account the operating parameters, characteristics and workings of the AX protocol. The RTU system has been successfully simulated using 2 ACS712 current sensors, voltage sensor, zero crossing point, frequency sensor and rotation sensor functional for monitoring Micro hydro power plant parameters. The AX.25 protocol has been applicable in the wireless SCADA network for monitoring the performance of the Micro hydro power plant by embedding in a KYL-1020UA transceiver radio using the 433 MHz frequency and the AFSK modulation system. Radio transmitter KYL-1020UA has been successfully simulated to send data from sensors to display on the computer through SCADA built applications. The data changes in the RTU section can be displayed properly on the GUI in accordance with the existing display at the Micro hydro power plant location.
