Judul: Deteksi Malware Berbasis System Call dengan Klasifikasi Support Vector Machine pada Android
Abstrak: Android is an operating system that is widely used in smartphone. The biggest threat in Android is the spread of malware that comes from Android application stores. Generally, malware use signature-based method which can be easily avoided by malware that has polymorphic capabilities. Thus, it requires more dynamic detection method. The purpose of this research is to see whether system calls can be used as features to detect Android malware and to test the accuracy of the Support Vector Machine (SVM) in classifying malware and non-malware applications using system call frequencies. The frequencies of system calls were obtained from the result of executing Android applications and unused system calls were excluded. After that, the Principal Component Analysis process was conducted to reduce the dimension and eliminate the irrelevant features. The use of Radial Basis Function kernel in SVM achieves 86.25% of malware classification while the polynomial kernel achieves 90% of malware classification.

Judul: Sistem Pakar Berbasis Android Untuk Identifikasi Jenis Gulma Pada Budidaya Tanaman Kedelai
Abstrak: Salah satu kendala yang sering terjadi pada kegiatan budidaya kedelai adalah masalah gulma yang berpotensi menurunkan produktivitas. Sehingga diperlukan sistem pakar yang dapat mewakili pengetahuan mengenai identifikasi jenis gulma agar petani dapat memutuskan pengendalian yang tepat. Penelitian ini bertujuan membuat sistem pakar berbasis android offline adalah untuk identifikasi jenis gulma pada budidaya tanaman kedelai berdasarkan informasi morfologi dan menentukan saran pengendalian gulma yang tepat. Metode forward chaining digunakan sebagai pengembangan mesin inferensi yang digunakan utuk memutuskan kesimpulan sistem pakar. Sistem pakar identifikasi jenis gulma yang dibangun berisi informasi jenis gulma, informasi pengelompokan gulma, informasi herbisida, takaran herbisida, dan galeri kegiatan pengendalian gulma. Ukuran aplikasi sebesar 6.97 Megabytes (Mb) dan berjalan tanpa koneksi internet. Pengujian aplikasi dapat berjalan dengan baik dengan akurasi identifikasi jenis gulma mencapai 87.5%.

Judul: Daya dan kestabilan buih putih telur itik tegal pada umur telur dan taraf penambahan asam sitrat yang berbeda
Abstrak: The usage of ducks egg for cake mixes is still rare since its foaming is lower than chicken egg. Albumen foaming and its stability are affected by egg age and chemical addition or stabilization. Chemical substance which can be used is citric acid. This research was designed to study whether albumen foaming and its stability of Tegal ducks egg in different age could be increased by adding citric acid in a given concentration before mixing. The result was hoped to supply information about the best albumen foaming and stability formed by Tegal duck egg by adding citric acid in different egg age. The research used Block Randomized Design factorial pattern. As first treatment were egg age which contained 4 factor levels; fresh, 7, 14 and 21 days of egg. Second treatment were citric acid addition, that also contained 4 factor levels; 0, 0.8, 1.6 and 2.4%. Egg which is collected in different days was used as block. The longer egg shelf life, the more block formed. Data which is obtained were analyzed by descriptive approach. The highest albumen foaming and its stability of Tegal ducks egg without citric acid addition was in fresh egg, which was 451.83±122.18% and 3.43±0.66% in leak percentage. Albumen foaming and its stability was decrease as egg age longer. Citric acid addition until 2.4% could increase albumen foaming and its stability only in fresh egg, with addition level best in 0.8%. This addition established foaming as much as 683.33±14.43% and 2.66±1.41% leak percentage.
