"ABSTRAK
Sekarang ini, tingkat kematangan buah pisang Musa sp diklasifikasikan secara manual berdasarkan warna kulitnya. Pada penelitian ini, akan diperkenakan sistem otomatis tingkat kematangan buah pisang menggunakan teknologi hyperspectral. Sistem perangkat keras yang digunakan terdiri dari satu set alat pengukuran, sumber cahaya halogen dan kamera hyperspectral yang terhubung ke PC melalui Camera Link. Perangkat lunak sistem terdiri dari pengukuran hasil reflektansi citra, ekstraksi ciri, dan algoritma klasifikasi. Citra reflektansi permukaan pisang dihitung berdasarkan citra yang didapat, white reference dan dark reference. Feature extraction ekstraksi ciri didapatkan menggunakan principal component analysis pada semua range panjang gelombang hyperspectral. Dengan demikian, tingkat kematangan diklasifikasikan menggunakan artificial neural network menjadi 3 kelas yaitu, mentah, matang dan sangat matang. Sampel yang digunakan ialah 15 pisang ambon Musa acuminate colla dan 15 pisang raja Musa textilla yang masing-masing berisi 5 sampel pada setiap tingkat kematangan. Hasil penelitian ini menunjukan bahwa sistem yang diusulkan dapat mengkalsifikasikan tingkat kematangan buah pisang cukup akurat.

ABSTRACT
Nowadays, the maturity of banana is classified manually based on the surface color of banana. In this study, an automatic system was introduce using hyperspectral technology system. The hardware of system consist of a set of measuring system, light source and hyperspectral camera that connect to PC via Camera Link. The software of system consists of reflectance image profile measurement, feature extraction and classification algorithm. The reflectance image profile of the banana surface was calculated based on current image, white and dark image reference. The feature sets were computed using a principal component analysis on full wavelength range of HIS spectra. Thus, the maturity stage of banana was classified artificial neural network into 3 classes i.e. immature, mature and very mature. The samples used were 15 sampel Musa acuminate collaa and 15 sampel Moses textilla which is consist 5 samples for each aturity stage.The results show that the proposed system can classify the banana maturity stage perfectly.

"Penelitian ini dilakukan untuk menguji kelayakan penerapan teknik pencitraan hiperspektral di wilayah variabel 400-1000 nm untuk mengetahui kandungan formalin. Sistem pencitraan hiperspektral terdiri dari kamera hiperspektral, slider, motor slider, dua sumber lampu halogen dan komputer yang digunakan untuk proses akuisisi data dan pengolahan data. Citra hiperspektral merupakan sebuah hypercube yang berisi informasi spasial dan spektral. ROI digunakan untuk memilih area sampel yang homogen. Data ROI diekstraksi dengan merata-ratakan data spasialnya, sehingga hanya diperoleh data spektral. Metode principle component analysis PCA digunakan untuk mereduksi dimensi data data spektral dan memilih fitur yang akan digunakan sebagai masukan dalam klasifikasi. Linear discriminant analysis LDA digunakan sebagai model untuk mengklasifikasikan kelas yang berbeda, yaitu formalin dan nonformalin. Model PCA regresi digunakan untuk menguji akurasi nilai prediksi terhadap nilai pengujian laboratorium. Dari hasil percobaan pada pengamatan hari pertama, kedua dan ketiga menunjukkan keefektifan model LDA dalam memisahkan sampel tahu berformalin dan tahu tanpa formalin dengan akurasi diatas 86,81 , 93,06 , dan 100 . Serta dari hasi regresi linier pada pengamatan hari pertama, kedua dan ketiga diperoleh koefisien korelasi R2 sebesar 0,98, 0,99 dan 0,99 serta nilai RMSE sebesar 1,83, 1,40 dan 1,27. Hasil ini menunjukkan bahwa pencitraan hiperspektral merupakan pendekatan yang menjanjikan untuk memprediksi kandungan formalin yang dengan cepat dan akurat.

This study was carried out to examine the feasibility of applying hiperspektral imaging technique in the spectral region 400 1000 nm for classification formaldehyde tofu. The system hardware of hiperspektral imaging consists of hiperspektral camera with spectral region 400 1000 nm, workbench, motor slider, two halogen lamp source and personal computer used for the data acquisition process and data processing. Hyperspectral image is a hypercube that contains of spatial and spectral information. ROI is used to select a homogeneous sample area. ROI data is extracted by averaging its spatial data, so that only spectral data are obtained. The principle component analysis PCA method is used to reduce dimensions of the data and select the features to be used as input in the classification. The linear discriminant analysis LDA is used as a model to classify to distinct classes, that is formaldehyde tofu and without formaldehyde tofu. PCA Regression model is used to test the accuracy prediction values against the value of laboratory testing. Result from the experiment on the first, second and third day observations showed the effectiveness of the LDA model in separating the informal sample of formalin and tofu without formalin with an accuracy above 86.81 , 93.06 , and 100 . As well as from the results of linear regression on first, second and third observations obtained correlation coefficient R2 of 0.98, 0.99 and 0.99 and RMSE of 1.83, 1.40 and 1.27. These results suggest that hyperspectral imaging is a promising approach to predicting rapidly and accurately formaldehyde content."

"ABSTRAK<>br>
Penelitian ini bertujuan untuk mengungkap penyaruan apa yang dilakukan SBY dalam pidato kenegaraannya pada tanggal 17 Juli 2009. Melalui pengkajian dari beberapa paragraf yang terdapat dalam pidato kenegaraannya, dan dihubungkan dengan teori praktik sosial dari Bourdieu Hasil penelitian ini memperlihatkan bahwa kekurangpercayaan masyarakat pada Soesilo Bambang Yudhoyono sebagai seorang presiden tampaknya dirasakan betul olehnya. Maka dari itu, SBY terus-menerus melakukan beragam cara demi menarik simpati dari rakyatnya. Misalnya cara yang dilakukannya dalam pidato kenegaraan tanggal 17 Juli 2009. Sayangnya, pidato kenegaraan itu dinilai sarat akan pencitraan yang dilakukan oleh SBY., Maka, dapat disimpulkan bahwa SBY telah melakukan penyaruan dalam pidato kenegaraannya.

ABSTRACT<>br>
Lack of public confidence to Yudhoyono, seems to be perceived well by himself. Therefore, SBY continues to make a variety ways to attract the sympathy of the people. As he did in his official speech on July 17, 2009. Unfortunately, the state speech reputed full imaging performed by SBY. This study aims to uncover what kind of imaging that SBY did in his speech on July 17, 2009. Through the assessment of several paragraphs contained in his speech, and social practices associated theory of Bourdieu, can be said that he has done an imaging SBY in his speech."

"This book offers a practical approach to the world of diagnostic ultrasound. It has been structured in a reader-friendly, case-based format that makes it easy and enjoyable to learn the basics of the applications and interpretation of ultrasound. Each case includes illustrations, descriptions of the imaging findings, and technical details and serves to identify the essential imaging features of the pathology under consideration, thus assisting the reader in the diagnosis of similar cases. The book is divided into 17 short chapters that review the most important areas of ultrasound application and also document the latest advances in the use of contrast and interventional ultrasound. The authors treat every topic from a “how to do it” perspective with the aim of imparting their wide experience in use of the technique. "
