Aplikasi Kriptografi Untuk Mengamankan File Audio Video Menggunakan Visual Basic .Net

In terms of file security is often diminished, because the file with the extension * and * .MP4 .MP3 is like the audio files that we secured was listening to the audio exams and video UAN English as exam for student/student in Ja Al-Haq is not given a security so that everyone can see the file. Application of cryptography to secure audio video files using visual basic Net made to secure the audio video files which are air-extension "* Mp3, Mp4 *" were built using the programming language Visual Basic Net. The encryption process is a process to convert the original video audio files into files that cannot be executed. Decryption process is a process to convert audio and video files into audio files randomly original video. Testing data security system is a test conducted to determine the safety data that has been integrated on a particular file, in this case the video audio file "* Mp3, * mp4"

Keterampilan Proses Sains dan Kemandirian Belajar Siswa: Profil dan Setting Pembelajaran untuk Melatihkannya

Telah dilakukan penelitian untuk menganalisis profil keterampilan proses sains dan kemandirian belajar siswa SMP pada sekolah di Kabupaten Grobogan. Penelitian dilakukan dengan menggunakan metode deskriptif dengan subjek penelitian sebanyak 60 siswa pada dua Sekolah Menengah Pertama di Kabupaten Grobogan. Data dikumpulkan menggunakan tes pilihan berganda, angket, lembar observasi, dan wawancara. Hasil penelitian menunjukan bahwa keterampilan-keterampilan proses sains perlu mendapat perhatian khusus agar dikembangkan dan dilatihkan dalam setiap diri siswa karena hanya dikuasasi oleh 20%-50% siswa, terutama keterampilan menginterpretasikan grafik dan berkomunikasi. Selain itu, kemandirian belajar siswa secara umum masih rendah sehingga perlu dilatihkan secara terus menerus dalam diri siswa. Inovasi model pembelajaran berbasis proyek menggunakan pendekatan saintifik dapat digunakan untuk meningkatkan keterampilan proses sains dan kemandirian belajar siswa

Kualitas Semen Beku Sapi Bali dengan Penambahan Berbagai Dosis Vitamin C pada Bahan Pengencer Skim Kuning Telur

The aim of this research was to know what the effect of C vitamin increament (ascorbat acid)in skim egg yolk extender to semen motility and life percentage of sperm cell. This research wasconducted in Regional Technical Service Unit-Regional Artificial Insemination Office Lampung,Terbanggi Besar District on 18 th --25 th April 2014. The treatment of this research are P1 (without Cvitamin increament), P2 (1,50 mM C vitamin increament), P3 (2,50 mM C vitamin increament), P4(3,50 mM C vitamin increament), P5 (4,50 mM C vitamin increament) in skim egg yolk extender andevery treatment repetitions for three times. The data obtained was analyzed by using variance analysis5%. Results of this research showed that increament C vitamin dosage into skim egg yolk extenderwas no significantly (P>0.05) to sperm motility and life percentage of sperm

Rancang Bangun Alat Germicidal Udara Menggunakan Sinar Ultraviolet

Pada penelitian ini, dilakukan rancang bangun desain alat germicidal udara menggunakan sinar ultraviolet. Sinar ultraviolet dengan panjang gelombang kurang dari 265 nm mempunyai kemampuan dalam menonaktifkan bakteri, virus dan protozoa tanpa mempengaruhi komposisi kimia fluida. Absorpsi terhadap radiasi ultraviolet oleh protein, RNA dan DNA dapat menyebabkan kematian dan mutasi sel. Oleh karena itu, sinar ultraviolet dapat digunakan sebagai germicidal untuk mengendalikan kontaminasi bakteri di udara sehingga akan menghasilkan udara yang steril untuk sistem saluran udara. Pada penelitian ini telah dilakukan pengujian laboratorium terhadap kemampuan alat dalam menonaktifkan bakteri. Pada pengujian laboratorium dilakukan penghitungan koloni bakteri pada media kultur NA dan PDA. Penghitungan dilakukan setelah melakukan isolasi pada media kultur selama 48 jam. Alat germicidal udara yang dibuat mampu menghasilkan udara yang steril. Setelah di treatment menggunakan alat germicidal selama (0, 15 , 30, 45) menit, jumlah koloni mikroorganisme fungi menjadi 102, 31, 11, 6. Sedangkan mikroorganisme bakteri jumlah koloni menjadi 207, 48, 25, 15. Kemampuan untuk mereduksi jumlah bakteri sangat signifikan yang mencapai 92.7% untuk mikroorganisme berjenis bakteri dan 94.1% fungi. Pada penelitian ini juga dilakukan pengukuran terhadap konsumsi daya alat dalam menonaktifkan bakteri. Pengukuran dilakukan terhadap tegangan AC dan tegangan DC pada alat. Tegangan AC yang diukur merupakan tegangan input dari modul power supply yang dipakai. Sedangkan tegangan DC merupakan tegangan input dari lampu dan fan yang menjadi komponen alat. Konsumsi daya alat total sebesar 14.08 watt. Sedangkan daya yang dikonsumsi fan sebesar 1.736 watt dan lampu ultraviolet sebesar 7.884 watt. Besarnya nilai losses daya pada modul pengubah tegangan 4.46 wat

Tinjauan Yuridis terhadap Abandonemen (Penyerahan Hak Milik Atas Benda Pertanggungan) dalam Hal Penyelesaian Klaim Asuransi Rangka Kapal (Marine Hull Insurance)

Insurance is a bilateral agreement in which the first party as an insured to pay the insurance premiums to the second party as the person who is willing to bear the losses suffered by the goods or services of value arising from the insured property. Development of marine insurance relating to the implementation of the transport or shipping is done through a sea full of marine hazards. In a sense, marine insurance is not just limited to the marine environment only, but will also include terrestrial environments and inland waters (rivers and lakes). The author uses the methods of normative research that focuses on secondary data or literature data as a primary source. From the results of research already done so authors can be concluded that the legal basis of insurance contained in the Book of Acts - Act trademark law (Commercial code), Act - Act 2 of 1992 concerning insurance undertakings. Marine insurance basically guarantees loss, damage (risk) as a result of the dangers of the sea. With the agreement of the insured's coverage then the risk is taken over by the insurer, provided that the insured must pay premiums for marine insurance. About the dangers - dangers that are borne not only limited to the hazards that occur at sea, but also about the dangers - dangers that can occur canal during transport, such as a fire hazard dipelabuhan. Basically, the insurance must have an element of the insured interests, compensation received shall be in accordance with what has been previously agreed upon closing of insurance, and payment of compensation can only be given after the loss that befell the insured. From these elements, the coverage made by the insurer and the insured would be void if the insured to speculate on the state of things - things that are not tru
