Judul: Lokalisasi Plat Nomor pada Kendaraan di Indonesia dengan Metode Dasar Vertical Egde Analysis.
Abstrak: Localization of license plate is a first stage in vehicle license plate recognition system. License plate localization affects the results of license plate recognition. In this research, the vertical edge analysis became the basic method of the license plate localization. First, pre-processing on the image is performed to obtain a better image quality. Secondly, the vertical edge detection on the image performed using the Sobel operator. Thirdly, candidate number plate detection is done by using a sliding window. This phase is divided into two processes: coarse detection and fine detection. At this stage the edge density will be calculated by using the concept of integral edge image. To separate the actual plate with objects that resemble plates, edge density calculation is performed in certain parts of the license plate candidates. Finally, the candidates are verified by counting the number of vertical pixels that exist on the license plate candidates. Of testing 70 cars image data, a recall value of 86.17% and a precision value of 60.75% are obtained.

Judul: Pembangunan Sistem Identifikasi Plat Nomor Kendaraan dengan Ekstraksi ciri Zoning dan Metode Klasifikasi K-NN
Abstrak: Sistem identifikasi plat nomor kendaraan memiliki peran penting dalam sistem transportasi. Pada penelitian ini proses identifikasi plat nomor kendaraan terbagi menjadi 3 tahap yaitu lokalisasi plat nomor, pemisahan karakter, dan pengenalan karakter. Penelitian ini menggunakan citra kendaran yang memiliki plat nomor standar Indonesia, pengujian dilakukan pada 60 data citra kendaraan. Pada tahap lokalisasi plat nomor, vertical edge analysis menjadi metode dasar pencarian plat. Tingkat akurasi lokalisasi plat pada pengujian ini sebesar 95%. Plat hasil lokalisasi dilakukan proses pemisahan karakter menggunakan 8-connected. Karakter yang telah terpisah dilakukan ekstraksi ciri ICZ+ZCZ dengan zona berjumlah 14, 20, dan 25. Klasifikasi K-NN dengan k=3 digunakan dalam identifikasi karakter. Hasilnya akurasi pengenalan karakter per plat nomor kendaraan menggunakan ekstraksi ciri ICZ+ZCZ dengan nilai k=3 memiliki tingkat akurasi terbaik pada zona berjumlah 14 yaitu 26.32% tanpa toleransi kesalahan dan 63.16% untuk toleransi kesalahan tidak lebih dari 1 karakter.

Judul: Nutritional Properties of Cocoa Pods as Ruminant Feedstuff
Abstrak: An attempt to increase cocoa pods quality feed for ruminant have been done using fermentation techniques with or without urea addition. Five treatments (Fresh cocoa pod = C; fermentation with addition urea 0 g/kg = U0 or ensilage; 10 g/kg = U1; 20 g/kg = U2 and 30 g/kg fresh substances of cocoa pods) have been examined for their effect on pH, proximate composition, N-fractions, amino acid compositions, cell wall constituents, anti nutritive compounds, in vitro gas production (Gb), estimate organic matter digestibility (OMD) and metabolizable energy (ME) of cocoa pods. Ensilage (U0) improve feed values of cocoa pods by weakening the lingo-cellulose or –hemicellulose bonds, resulting in higher in vitro gas production as well as higher OMD and ME contents compare to fresh cocoa pods. The protein value of cocoa pods, expressed as true protein (TP) or non ammonia nitrogen (NAN) minus urea nitrogen (UR) was also improved. Addition of urea affected the composition of the fibre fraction as to the proportion of NDF, ADF and ADL and the content of TP was slightly increased. Urea treatment increased Gb, OMD and ME compared to ensiled or fresh cocoa pods. The optimum level of urea for maximum Gb was 6.7 g/100 g DM cocoa pods. The optimum level to reach maximum OMD and ME were also reached at urea level 6.5 – 6.7 g/100 g DM cocoa pods.
