It was found that some universities were using technology to falsify transcripts. An example of a university in yogyakarta's special region that falsified academic transcripts. Several diplomas from makassar have been forged so that a civil servant can pass his exam, whereas in banda aceh evidence of equipment for creating fake diplomas has been found. This study seeks to prevent transcripts from being modified or falsified by locking data into student photos using blowfish and least significant bit algorithms. The purpose of this study is to keep transcripts from being easily modified or falsified. The methods of this study are data collection (student code data, gpa value, photo), encryption with blowfish, conversion of encryption results into binary form, insertion of binary values into the least ...

Penelitian ini bertujuan untuk menguji perbedaan kinerja sistem operasi server antara FreeBSD 8.2 dengan Fedora 15 dengan metode uji independent samples test. Perubahan konfigurasi pada file sysctl.conf digunakan untuk optimasi parameter kernel sistem operasi pada saat berjalan dan file my.cnf digunakan untuk membagi sumber daya memori (RAM) untuk menjalankan perintah menyesuaikan kebutuhan yang ada dengan kapasitas RAM yang digunakan. Pengukuran kinerja dilakukan menggunakan aplikasi Sysbench dengan memberi 20 syntax yang berbeda dimana perbedaan terletak pada pemberian nilai numthreads. Nilai tersebut diasumsikan sebagai banyaknya jumlah klien yang melakukan perintah kepada server. Sampel data yang dianalisa mengambil nilai rata-rata waktu eksekusi setiap perintah pada hasil pengukuran yang dilakukan dengan aplikasi Sysbench. Untuk mengetahui kenormalan distribusi sampel data dilakukan pengujian dengan metode uji normalitas Kolmogorov-Smirnov. Dan untuk mengetahui homogenitas varian sampel data dilakukan dengan metode uji homogenitas Lavene. Pengujian hipotesis dilakukan dengan metode uji independent samples t-test. Uji ini digunakan untuk mengetahui ada atau tidaknya perbedaan rata-rata antara dua kelompok sampel yang tidak berhubungan. Hasil dari penelitian diketahui bahwa nilai ratarata waktu setiap eksekusi perintah pada sistem operasi server Fedora 15 lebih tinggi dibanding FreeBSD 8.2, dengan selisih sebesar 0,346 detik, akan tetapi hal itu masih masuk dalam nilai toleransi (taraf kepercayaan/Confidence Interval of the Difference = 95%), sehingga dapat disimpulkan bahwa nilai rata-rata waktu setiap eksekusi perintah pada kedua sistem operasi adalah sama (tidak ada perbedaan yang signifikan).

Target utamanya adalah para pelaku usaha mikro kecil menengah dan mempunyai tujuan untuk membantu mengembangkan usaha mikro di indonesia. Sistem pendukung keputusan dibuat untuk membantu dan memberikan alternatif dalam menentukan kelayakan debitur pengajuan pembiayaan mikro. Metode yang digunakan dalam pembuatan SPK ini adalah Simple Additive Weighting. SAW dipilih karena metode ini mampu menyeleksi alternatif terbaik dari sejumlah alternatif berdasarkan kriteria yang ditentukan. Penelitian dilakukan dengan mencari nilai bobot untuk setiap kriteria, kemudian dilakukan perangkingan berdasarkan grade perusahaan yang akan menentukan alternatif paling baik, dalam hal ini debitur teladan. Berdasarkan hasil pengujian aplikasi ini sangat membantu tim penyeleksi memberikan alternatif pembanding dalam menentukan kelayakan debitur karena hasil keluaran dari aplikasi ini berupa skor total dengan nilai maksimal 100 dan menggunakan grade yang tinggi yaitu 70. Pembobotan kriteria di titik beratkan pada karakter (30), daya jual jaminan (20), laporan keuangan (15), jenis pekerjaan (15), lokasi jaminan (10) dan lokasi tinggal (10) sehingga debitur yang lolos mempunyai kriteria yang bagus.

Consequently, customers require more effort to search for products. In this study, we classified products from several e-marketplaces. The classification was carried out using TF-IDF method for the weighting, cosine similarity to calculate product similarity distance, and k-nearest neighbor algorithm. Based on the first testing result using 150 product data, the k-nearest neighbor method with k=5 successfully classified 146 data with 4 data classified into the wrong class. This k=5 value gives the best result for this case, with an accuracy of 97.33%. The second testing result using 150 mixed brand product data, the k-nearest neighbor method successfully classified 145 data with 5 data classified into the wrong class. The accuracy of the second testing is 96.67%.
