“…Metode yang digunakan adalah Wiener Estimation dengan akurasi mencapai 73.61%. Estimasi reflectance pada daun jati belanda menggunakan transformasi Fourier menghasilkan nilai error dan Goodness of Fit Coefficient (GFC) sebesar 4.83 dan 0.96 (Lantana et al 2014). Model reflectance juga diterapkan untuk mengestimasi reflectance pada citra lukisan (Mansouri et al 2008).…”

Jati belanda (Guazuma ulmifolia) adalah salah satu tanaman yang berkhasiat sebagai antioksidan karena pengaruh senyawa aktif yang terkandung di dalamnya. Cahaya pantulan (reflectance) dapat digunakan untuk mengetahui kualitas senyawa aktif pada daun jati belanda. Penelitian ini membahas tentang estimasi spektrum reflectance citra digital daun jati belanda menggunakan model reflectance daun tanaman obat dengan menerapkan transformasi wavelet. Bahan yang digunakan adalah daun tanaman obat dan daun jati belanda. Transformasi wavelet digunakan untuk merepresentasikan reflectance daun tanaman obat. Model polinomial diterapkan untuk mengekspansi ciri citra digital. Model reflectance terbaik dari penerapan transformasi wavelet dan model polinomial digunakan untuk mengestimasi reflectance dari daun jati belanda. Evaluasi spektrum reflectance asli dengan spektrum keluaran model estimasi reflectance menggunakan kriteria kesalahan terkecil dan kemiripan terbesar.Kata kunci: jati belanda, model polinomial, reflectance, wavelet

“…Penggunaan transformasi wavelet menghasilkan model estimasi reflectance yang lebih baik dari penggunaan transformasi Fourier. Penggunaan transformasi Fourier menghasilkan RMSE dan GFC dengan nilai 4.83 dan 0.96 (Lantana et al 2014). Penerapan dekomposisi wavelet Haar level 3 menghasilkan RMSE dan GFC sebesar 3.89 dan 0.99.…”

“…Besides on its formula, research about jamu is also performed on the plant's physical appearances. Lantana et al [12] proposed a new method for estimating spectral reflectance from jati belanda (Guazuma ulmifolia) leaf based on digital image color, which then can be used to estimate chemical compounds contained in the leaf. Meanwhile, Karlitasari et al [13] developed a mobile application for visualizing Indonesia medicine in 3D.…”

Algorithm for Predicting Compound Protein Interaction Using Tanimoto Similarity and Klekota-roth Fingerprint

2018

This research aimed to develop a method for predicting interaction between chemical compounds contained in herbs and proteins related to particular disease. The algorithm of this method is based on binary local models algorithm, with protein similarity section is omitted. Klekota-Roth fingerprint is used for the compound's representation. In the development process of the method, three similarity functions are compared: Tanimoto, Cosine, and Dice. Youden's index is used to evaluate optimum threshold value. The result showed that Tanimoto similarity function yielded higher similarity values and higher AUC value than those of the other two functions. Moreover, the optimum threshold value obtained is 0.65. Therefore, Tanimoto similarity function and threshold value 0.65 are selected to be used on the prediction method. The average evaluation accuracy of the developed algorithm is only about 50%. The low accuracy value is allegedly caused by the only use of compound similarity on the prediction method, without including the protein similarity.
