Abstract

Cassava or better known as cassava is one of the staples of rice which is popular in Indonesia. Cassava plants can flourish in almost all regions of Indonesia. However, cassava is a plant that is susceptible to plant disease, which attacks the disease resulting in a decrease in the amount of productivity of tubers produced by cassava plants. The application of identifying cassava disease based on leaf image is expected to be useful as a support for cassava farming in easily detecting cassava disease, so that it can be dealt with more quickly. This study uses the Gray Level Co-occurrence Matrix (GLCM) method as an extraction feature and the Probabilistic Neural Network (PNN) method for identification processes. Based on the results of tests on 6 types of cassava leaf images, obtained an accuracy of 83.33%.

Abstract

Food security is still one of the main issues faced by Indonesia due to its large population. Rice as a staple food in Indonesia has experienced a decline in production caused by unpredictable climate change. In dealing with climate change, adaptation to fluctuating rice productivity must be made. This study aims to build a prediction model of wetland rice production on climate change in South Kalimantan Province which is one of the national rice granary province and the number one rice producer in Kalimantan Island. This study uses monthly climatic data from Syamsudin Noor Meteorological Station and quarterly wetland rice production data from Central Bureau of Statistics of South Kalimantan. In this research, Support Vector Regression (SVR) method is used to model the effect of climate change on wetland rice production in South Kalimantan. The model is then used to predict the amount of wetland rice production in South Kalimantan. The results showed that the prediction model with the RBF kernel with the parameter of C=1.0, epsilon=0.002 and gamma=0.2 produces good results with the RMSE value of 0.1392.

Abstract

Traffic congestion has raised worldwide as a result of growing motorization, urbanization, and population. In fact, congestion reduces the efficiency of transportation infrastructure usage and increases travel time, air pollutions as well as fuel consumption. Then, Intelligent Transportation System (ITS) comes as a solution of this problem by implementing information technology and communications networks. One classical option of Intelligent Transportation Systems is video camera technology. Particularly, the video system has been applied to collect traffic data including vehicle detection and analysis. However, this application still has limitation when it has to deal with a complex traffic and environmental condition. Thus, the research proposes OTSU, FCM and K-means methods and their comparison in video image processing. OTSU is a classical algorithm used in image segmentation, which is able to cluster pixels into foreground and background. However, only FCM (Fuzzy C-Means) and K-means algorithms have been successfully applied to cluster pixels without supervision. Therefore, these methods seem to be more potential to generate the MSE values for defining a clearer threshold for background subtraction on a moving object with varying environmental conditions. Comparison of these methods is assessed from MSE and PSNR values. The best MSE result is demonstrated from K-means and a good PSNR is obtained from FCM. Thus, the application of the clustering algorithms in detection of moving objects in various condition is more promising.

Abstract

The study presents a road pavement crack detection system by extracting picture features then classifying them based on image features. The applied feature extraction method is the gray level co-occurrence matrices (GLCM). This method employs two order measurements. The first order utilizes statistical calculations based on the pixel value of the original image alone, such as variance, and does not pay attention to the neighboring pixel relationship. In the second order, the relationship between the two pixel-pairs of the original image is taken into account. Inspired by the recent success in implementing Supervised Learning in computer vision, the applied method for classification is artificial neural network (ANN). Datasets, which are used for evaluation are collected from low-cost smart phones. The results show that feature extraction using GLCM can provide good accuracy that is equal to 90%.

Abstract

Often fish supply in to the consumers need long relatives distance and much time. Meanwhile the consumers always want fresh fish. The problem occurred was broken stock of fresh fish in every shipping and happened almost all the time. It made fish became stale and made supplier got lose. The study was took place in Batulicin Simpang Empat in a harbor (Pelelangan Pembongkaran Ikan)  until now the handling of fish catches generally used ice block in the usual cool box. Using ice block is one of easiest method. Although, using ice block only could maintain low temperature in short time whereas the ideal temperature of cool box should be 10  Celsius measured by usual temperature’s device room. In shipping process, the driver unpack the cool box to checked temperaturemanually. This matter waste time and cost because the driver should provide extra ice block to maintain low temperature of cool box. In order to resolve the problem, monitoring could be done automatically by using a microcontroller chip in the cool box with DS18B20 censor and fuzzy methodbase microcontroller. The purpose was supplier could be helped to monitoring the stabilities of cool box temperature used website. This system is made by computerization. It would make supplier job easier because driver able to check fish condition without unpack the cool box and made time, energy and cost more efficient.Keywords: Temperature Censor, Fish cool box microcontroller, Fuzzy method, and websiteSeringkali dalam penyuplaian ikan kepada konsumen membutuhkan jarak dan waktu yang relatif panjang, sedangkan konsumen selalu mengharapkan ikan segar. Permasalahan besar yang dihadapi dalam produksi ikan segar, yaitu persediaan yang rusak (broken stock) dalam jumlah yang banyak, sehingga jumlah ikan yang membusuk menjadi berlebihan dan akhirnya mengalami kerugian. Di Batulicin Simpang Empat, tempat dilakukanya penelitian, tepatnya di pelabuhan PPI (Pelelangan Pembongkaran Ikan), penanganan hasil tangkapan ikan saat ini masih menggunakan pendinginan es batu di dalam cool box biasa. Penggunaan es merupakan salah satu cara yang paling mudah dilakukan. Akan tetapi, pendinginan dengan menggunakan es batu  hanya dapat mempertahankan suhu rendah dalam waktu yang singkat sedangkan suhu ideal dari dalam cool box adalah 10 C yang diukur dengan menggunakan alat suhu ruangan biasa. Jadi, saat perjalanan driver akan membongkar muatan dan mengecek apakah suhu turun atau tidak secara manual. Hal ini sangat memakan waktu dan biaya karena supplier selalu membawa cadangan es untuk berjaga-jaga jika suhu turun didalam cool box tersebut. Untuk mengatasi permasalahan di atas, monitoring dapat dilakukan secara otomatis dengan memanfaatkan sebuah chip mikrokontroler pada cool box dengan sensor DS18B20 bersama metode fuzzy berbasis mikrokontroler. Tujuannya agar supplier dapat terbantu untuk memonitoring kestabilan suhu cool box dengan menggunakan website. Karena sistem dibuat terkomputerisasi maka akan memudahkan kinerja dari supplier atau driver sehingga driver dapat memonitor kondisi ikan di dalam cool box tanpa harus membongkar muatan dan hal ini dapan mengefisiensikan waktu, tenaga, dan biaya karena suhu cool box tetap terjaga dengan baik  dan mudah.Kata kunci: Sensor Suhu, Mikrokontroler Cool Box Ikan,  Metode Fuzzy, dan website
