Abstract

Komando Rayon Militer (Koramil) merupakan satuan komando kewilayahan terkecil dari Tentara Nasional Indonesia (TNI) yang terletak di setiap kecamatan yang berperan sebagai pelaksanaan Sistem Pertahanan Keamanan Rakyat Semesta (sishankamrata). Berdasarkan UU nomor 3 tahun 2002 tentang Pertahanan Negara, Koramil memiliki tugas pokok menyelenggarakan pembinaan teritorial dalam rangka mempersiapkan wilayah pertahanan di darat dan menjaga keamanan wilayahnya untuk mendukung tugas pokok Komando Distrik Militer (Kodim). Pembinaan territorial meliputi segala unsur wilayah geografi, demografi dan kondisi social agar tercipta suatu kekuatan wilayah yang tangguh dalam mengatasi segala ancaman, gangguan dan hambatan yang mengganggu kelangsungan hidup berbangsa dan bernegara serta jalannya pembangunan nasional. Mengingat pentingnya fungsi Koramil dan harus adanya kerja sama antara masyarakat dan Koramil, maka anggota Koramil harus mengetahui daerah binaannya, begitu juga masyarakat yang kesulitan mengetahui Koramil mana yang membina daerahnya dan kegiatan ataupun kejadian apa yang ada di daerahnya, maka di bangun Sistem Informasi Geografis Persebaran Komando Rayon Militer (Koramil) untuk mempermudah anggota serta masyarakat mengetahui informasi letak koramil dan wilayah yang dibina. Metodologi penelitian sistem menggunakan metode waterfall dalam pengembangannya dengan pemetaan menggunakan teknologi Google Maps. Pada sistem terdapat Admin (Kodim dan Koramil) dan User pengguna (Anggota dan Masyarakat). Sistem ini memiliki fitur perbesaran (zoom in) dan pengecilan (zoom out), menampilkan rute dan jarak terdekat menuju koramil, serta informasi kegiatan yang sudah dilaksanakan dan belum dilaksanakan. Pengunjung juga dapat melihat tingkat kejadian disetiap kelurahan melalui diagram statistik setiap bulannya sehingga masyarakat dapat bekerjsama untuk meningkatkan keamanan dan pertahanan wilayah.

Abstract

The large number of users and the items offered in e-commerce make it difficult for buyers to choose the right items and sellers to offer their items to the right buyers. To overcome this problem, a system that can offer and recommend goods automatically, namely a recommendation system is needed. One of the most popular methods used to create a recommendation system is collaborative filtering, the recommendations are created based on similarities in user behavior. Unfortunately, this method has a weakness, namely cold start, where the recommendations will be inaccurate on data that has a lot of new users and items due to minimal historical data regarding user behavior. This problem will be tried to be solved in this study using a hybrid method, where this method combines more than 1 method to create a list of recommendations so that it will cover the shortcomings of each method. This study uses Amazon's e-commerce product and transaction data. The use of the hybrid method in this study can overcome the cold start problem by using switching and mixed methods, by not using the collaborative filtering model on new user recommendations or users who have little interaction. New users will receive recommendations based on the combination of popularity-based and content-based filtering models. This can be seen from the Mean Absolute Error (MAE) value of the model, where the MAE value for the data with a minimum user has at least 3 times rating is 0.566883, for the minimum 7 times, the MAE value is smaller, 0.487553.

Abstract

Purpose: To determine the effect of implementing Histogram equalization (HE) at the image preprocessing stage to improve image quality in rhizome spice classification using the K-Nearest Neighbor classification method.Design/Method/Approach: Rhizome spice data was taken directly using a camera with a total of 600 images divided by a ratio of 80:20 for training and testing data. Preprocessing is done starting from resize to 512x512 pixels, then remove background to remove background objects that are not needed, then histogram equalization and also grayscale conversion. Glcm texture feature modeling, rgb color feature and hsv color feature are used as classification parameters. Classification is done using the K-Nearest Neighbor (KNN) method.Findings/result: The test results of this study can be concluded that the application of HE at the image preprocessing stage succeeded in improving classification performance as seen from the accuracy evaluation value. In KNN classification without preprocessing histogram equalization gets an accuracy of 73.8%.  When implementing histogram equalization the classification accuracy increases to 76.1%.From the two accuracy results obtained, it can be seen that the implementation of histogram equalization has a good effect in increasing the accuracy of classification.Originality/value/state of the art: The application of Histogram equalization (HE) in image preprocessing is able to improve image quality so that classification accuracy can increase compared to without using histogram equalization preprocessing.

Abstract

Semakin tinggi kualitas suatu citra maka semakin detail informasi yang akan di peroleh. Tetapi, tidak semua wilayah citra memungkinkan untuk dilakukan analisis dengan kecepatan proses yang tinggi. Pemilihan algoritma yang tepat berpengaruh terhadap kecepatan waktu pemrosesan. Apabila tidak ada pembatasan untuk area yang akan di proses mengakibatkan waktu pemrosesan secara realtime melebihi waktu pemrosesan maksimal yang seharusnya. Tingginya waktu pemrosesan yang terjadi mengakibatkan aliran data menjadi kurang cepat. Sarana/processor yang digunakan juga mampu mempengaruhi kecepatan pemrosesan. Region Of Interest (ROI) adalah cara yang tepat untuk mengurangi tingginya waktu pemrosesan tersebut. ROI mampu menandai area tertentu sehingga dapat digunakan untuk mengoptimalisasikan kinerja sistem untuk mendeteksi, menghitung dan mengklasifikasi kendaraan secara realtime. Tanpa adanya ROI, pemrosesan dilakukan pada seluruh piksel citra tanpa terkecuali. Terdapat beberapa tahapan yang dilakukan di dalam penelitian yaitu menganalisis masalah yang ada, penentuan wilayah ROI, aplikasi ROI sebelum proses pengolahan citra dan menganalisis hasil yang di dapatkan.  Hasil yang diperoleh adalah dengan menggunakan ROI waktu pemrosesan citra menggunakan metode segmentasi MOG2 dan tracking dapat lebih cepat dibandingkan dengan waktu pemrosesan ketika tidak menggunakan ROI dengan selisih 0,026 s atau setara dengan 26 ms/frame. AbstractIncreasing resolution of an image is more detailed information will be obtained especially in the image used to detect vehicles. But, every singles areas are not allow to analize with higher speed process. If there are no restrictions for the area to be processed, the processing time in real time exceeds the maximum processing time that should be. The high processing time that occurs make less rapid data flow. The high processing time can affect to processing speed. Region Of Interest (ROI) is the right way to reduce the high processing time. ROI is able to mark certain areas so that it can be used to optimize system performance to detect, calculate and classify vehicles in realtime. Without ROI, processing is carried out on all pixels without exception. There are several steps taken in the research, namely analyzing existing problems, determining the ROI area, application of ROI before the image processing and analyzing the results obtained. The results obtained are by using ROI image processing time can be faster than the processing time when not using ROI.
