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

Al-Gazālī is views  as a figure who succeeded to reconciled between  the Sharia with Sufism, and it was he who succeeded to make the teaching of sufism be accepted by the fiqh ulamahis  (scholars of Fiqh). Sufism is the final  path which he chose before which he  intensely studied the sensory sciences, theology, and philosophy. It was in Sufism, according to him, that he found the true knowledge which comes from the Creator.Kata Kunci: analisis sufisme. Al-Ghazali, syariat, tasawuf

Abstract

The rhizome of ginger is commonly used as a spice, food, beverage as well as medicine. Plant essential oils including from ginger have been widely used for food preservation, pharmaceutical and alternative medicines.  Currently there are growing interest of consumer for natural sources such as essential oils for natural antibacterial and antioxidant.  Jahe emprit (Zingiber officinale var. Amarum) is one of Indonesian ginger variety used to obtain ginger essential oil. The objective of current study was to investigate the effect of solvent to feed (SF) ratio in hydrodistillation process on yield, chemicals content, antibacterial and antioxidant activities of ginger essential oils from jahe emprit.  SF ratio used in this study is 0.7: 1, 1.7: 1, 2.7: 1.  Chemicals content was conducted using GCMS analysis.  Antibacterial assay was conducted using disc diffusion method against Escherichia coli and Staphylococcus aureus.  Antioxidant assay was conducted using DPPH free radical scavenging assay.  The results show that the highest essential oil yield was obtained from SF ratio 1.7:1 which gave yield of 3.7%.  GCMS analysis shows that camphene was always the major compound present in those 3 SF ratio, although the amount present was differed.  Besides, 4 other major compounds present were varied.  Antibacterial assay using 1% concentration showed ginger oil obtained from SF 0.7:1 and 2.7:1 have the same activities for S. aureus, whereas SF ratio 1.7:1 has the lowest activities.  However for E. coli, all SF ratio gave same results.  For antioxidant activities at 1000 ppm concentration, the highest activity was obtained from SF ratio 2.7:1

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: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.
