Anggrek merupakan tanaman bunga hias dalam Family Orchidaceae yang habitatnya terdistribusi pada hampir seluruh benua didunia, kecuali benua Antartika.  Di Indonesia sendiri, sangat banyak peminat anggrek sehingga menjadikan bunga ini sebagai komoditas yang cukup menjanjikan bagi penggiat tanaman hias.  Dengan ragam jenis anggrek yang mencapai lebih dari 25.000 spesies, identifikasi jenis anggrek menjadi sedikit rumit bagi para pecinta anggrek.  Tujuan penelitian ini adalah untuk menentukan tingkat akurasi pengidentifikasian jenis anggrek melalui pengenalan gambar, sehingga dapat menjadi acuan dalam menentukan kelayakan metode tersebut.  Penelitian ini menggunakan 120 citra anggrek yang terdiri dari 6 spesies.  Citra anggrek tersebut diperoleh dengan melakukan pemotretan pada beberapa lokasi menggunakan kamera.  Foto tersebut kemudian diolah menggunakan software pengolah citra dengan melakukan cropping dan resizing untuk mempercepat waktu komputasi saat pelatihan jaringan.  Selanjutnya software MatLab digunakan untuk melakukan proses ektraksi ciri berupa data warna dan moment invariants. Data hasil ekstraksi ciri dijadikan input untuk melatih jaringan syaraf tiruan dengan metode Back Propagation.  Penghitungan tingkat akurasinya dengan uji coba menggunakan data uji yang sudah disediakan. Hasil uji coba menunjukkan bahwa 26 dari 30 berhasil dikenali sehingga tingkat akurasi dapat dihitung yaitu 86,7%.  Tingkat akurasi sebesar 86,7% dapat dianggap layak dan bisa dijadikan landasan pertimbangan untuk menggunakan metode yang diuji coba ini sebagai metode yang tepat dalam melakukan identifikasi anggrek melalui citra.

The establishing of a precise simulation model for runoff prediction in river with several tributaries is the difficulty of flood forecast, which is also one of the difficulties in hydrologic research. Due to the theory of Artificial Neural Network, using Back Propagation algorithm, the flood forecast model for ShiLiAn hydrologic station in Minjiang River is constructed and validated in this study. Through test, the result shows that the forecast accuracy is satisfied for all check standards of flood forecast and then proves the feasibility of using nonlinear method for flood forecast. This study provides a new method and reference for flood control and water resources management in the local region.

Review Reports

The present review reports the work done by the various authors towards rainfall forecasting using the different techniques within Artificial Neural Network concepts. Back-Propagation, Auto-Regressive Moving Average (ARIMA), ANN , K- Nearest Neighbourhood (K-NN), Hybrid model (Wavelet-ANN), Hybrid Wavelet-NARX model, Rainfall-runoff models, (Two-stage optimization technique), Adaptive Basis Function Neural Network (ABFNN), Multilayer perceptron, etc., algorithms/technologies were reviewed. A tabular representation was used to compare the above-mentioned technologies for rainfall predictions. In most of the articles, training and testing, accuracy was found more than 95%. The rainfall prediction done using the ANN techniques was found much superior to the other techniques like Numerical Weather Prediction (NWP) and Statistical Method because of the non-linear and complex physical conditions affecting the occurrence of rainfall.

This study examines the potential of artificial neural network (ANN) to predict Total Volatile Organic Compounds (TVOCs) released via decomposition of local food wastes. To mimic the decomposition process, a bioreactor was designed to stimulate the food waste storage condition. The food waste was modeled based on the waste composition from a residential area. A feed forward multilayer back propagation (Levenberg – Marquardt training algorithm) was then developed to predict the TVOCs. The findings indicate that a two-layer artificial neuron network (ANN) with six input variables and these include (outside and inside temperature, pH, moisture content, oxygen level, relative humidity) with a total of eighty eight (88) data are used for the modeling purpose. The network with the highest regression coefficient (R) is 0.9967 and the lowest Mean Square Error (MSE) is 0.00012 (nearest to the value of zero) has been selected as the Optimum ANN model. The findings of this study suggest the most suitable ANN model that befits the research objective is ANN model with one (1) hidden layer with fifteen (15) hidden neurons. Additionally, it is critical to note that the results from the experiment and predicted model are in good agreement.

The artificial neural network (ANN) modeling ofm-cresol photodegradation was carried out for determination of the optimum and importance values of the effective variables to achieve the maximum efficiency. The photodegradation was carried out in the suspension of synthesized manganese doped ZnO nanoparticles under visible-light irradiation. The input considered effective variables of the photodegradation were irradiation time, pH, photocatalyst amount, and concentration ofm-cresol while the efficiency was the only response as output. The performed experiments were designed into three data sets such as training, testing, and validation that were randomly splitted by the software’s option. To obtain the optimum topologies, ANN was trained by quick propagation (QP), Incremental Back Propagation (IBP), Batch Back Propagation (BBP), and Levenberg-Marquardt (LM) algorithms for testing data set. The topologies were determined by the indicator of minimized root mean squared error (RMSE) for each algorithm. According to the indicator, the QP-4-8-1, IBP-4-15-1, BBP-4-6-1, and LM-4-10-1 were selected as the optimized topologies. Among the topologies, QP-4-8-1 has presented the minimum RMSE and absolute average deviation as well as maximum R-squared. Therefore, QP-4-8-1 was selected as final model for validation test and navigation of the process. The model was used for determination of the optimum values of the effective variables by a few three-dimensional plots. The optimum points of the variables were confirmed by further validated experiments. Moreover, the model predicted the relative importance of the variables which showed none of them was neglectable in this work.
