Abstract

License plate recognition (LPR) is one of the classical problems in the field of object recognition. Its application is very crucial in the automation of transportation system since it helps to recognise a vehicle identity, which information is stored in the license plate. LPR usually consists of three major phases: pre-processing, license plate localisation, optical character recognition (OCR). Despite being classical, its implementation faced with much more complicated problems in the real scenario. This paper proposed an improved LPR algorithm based on modified horizontal-vertical edge Projection. The method uses for detecting and localising the region of interest. It is done using the horizontal and vertical projection of the image. Related works proved that the modified horizontal-vertical edge projection is the simplest method to be implemented, yet very effective against Indonesian license plate. However, its performance gets reduced when specular reflection occurs in the sample image. Therefore, morphological operations are utilised in the pre-processing phase to reduce such effects while preserving the needed information. Eighty sample images which captured using various camera configurations were used in this research. Based on the experimental results, our proposed algorithm shows an improvement compared with the previous study and successfully detect 71 license plates in 80 image samples which results in 88.75% accuracy.

Abstract

Untuk mengurangi populasi kupu-kupu, perlu adanya strategi untuk memantau jumlah dan spesies yang ada pada masing-masing ekosistem. Peran teknologi dapat membantu dalam proses ini, misalnya pengembangan sistem e-Butterfly untuk mengumpulkan gambar spesies kupu-kupu dari berbagai wilayah sehingga dapat diketahui jenis spesies yang masih ada dan letak wilayah hidupnya. Identifikasi spesies kupu-kupu dapat dilakukan dan dibantu oleh komputer dengan serangkaian proses lebih spesifik pada cabang ilmu machine learning dan image processing. Tujuan dari penelitian ini adalah untuk mengetahui kinerja (performance) dari model model arsitektur VGG16 dan MobileNetV2 untuk klasifikasi citra gambar kupu-kupu berdasarkan hasil ekstraksi fitur pada citra gambar tersebut. Dataset penelitian berisi 4955 gambar yang kemudian diberi label 50 butterfly species dengan ukuran 224 X 224 X 3. Akurasi terbaik diperoleh MobileNetV2 tanpa fine-tuning yaitu mencapai presentase 96%, dilanjutkan dengan VGG16 dengan fine-tuning, MobileNetV2 dengan fine-tuning, dan akurasi testing paling kecil diperoleh VGG16 tanpa fine-tuning. Untuk nilai precision, recall, F1-Score, dan Cohens Kappa lebih tinggi diperoleh model MobileNetV2 tanpa fine tuning, hal ini menunjukkan bahwa MobileNetV2 tanpa fine tuning lebih imbang dalam akurasi tiap kelasnya.

Abstract

DKR Jatisampurna Bekasi is a Group of Scout Members in the Jatisampurna area who are responsible for scouting management. Every year DKR Jatisampurna will choose the Most Active Ambalan in the Jatisampurna area. This study intends to get DKR Jatisampurna's active ambalan using Profile Matching. The Profile Matching method is used to compare individual/school competencies into competencies as the best shelves so that differences in competence (Gap Value) can be identified. The smaller the Gap Value generated, the greater the weighted score, which means that there is a greater opportunity for individuals/schools to become the best Troops in Jatisampurna district. The criteria provided by DKR Jatisampurna include the criteria of 35% Activeness, 35% Organizational, and 35% Non-Organizational. The three criteria are further divided into core and secondary factors, with the provisions of DKR Jatisampurna 50% core factor and 50% secondary for Activeness criteria, 60% core factor and 40% secondary for Organizational aspects, and 40% core factor and 60% secondary for non-organizational criteria. The end result of the profile matching process is the ranking of the shelves that can be used as the best shelves. Ranking is determined from the total value of the assessment sorted from the largest value to the smallest, where the alternative with the largest total value is selected as the final result. The profile matching method for determining the most active ambalan at DKR Jatisampurna Bekasi has worked well, with the highest score of 4.376875 for SMKN 14.

Abstract

Prayer is the second pillar of Islam and it is emphasized after the two sentences of syahadat. It has been said that it’s as perfect and as good as worship. Prayer is one of the obligations for Muslims and must be done both for Mukimin and Musafir. The virtue of prayer in the mosque is the same as the value of 20 degrees of reward compared to prayer elsewhere. With the traffic jam phenomenon that is increasing due to heavy traffic. For someone who is traveling home in the afternoon before maghrib, some people are always confused to do Maghrib prayer because of the lack of information about the nearest mosque. The problem can be solved by finding the shortest path is a problem to find the minimum route from the starting point to the destination point with the shortest route. This research was made to design an application that provides direction to the nearest mosque in the area of Larangan, Tangerang city. In the making of this system to find the shortest path can be solved using the haversine formula and using the java programming language, where java is used to build applications while the database used is the MySQL database and the use of Google Maps API in determining the route.

Abstract

This study aims to evaluate the quality of internet network in Badan Penghubung Lampung using the TIPHON standard. The assessment is conducted by measuring several network performance parameters, including bandwidth, throughput, delay, and packet loss. The measurements are carried out for four days during office hours using the Axence Nettools 5 and speedtest.net applications. The collected data is then analyzed to obtain the average values for each parameter. The measurement results indicate that the overall quality of the internet network in Badan Penghubung Lampung is classified as very good. The average throughput value is 1,636 Kbps, which exceeds the TIPHON standard. The delay parameter has an average of 40.17 ms, which also meets the TIPHON standard. Meanwhile, the packet loss has an average of 2.75%, which is well below the maximum limit set by the TIPHON standard. However, this study also shows that the throughput value can be influenced by varying weather conditions, with the lowest data transfer speed occurring on the last day of the study. Therefore, for a more comprehensive evaluation of network quality, it is recommended to consider other parameters such as jitter, reliability, and availability.

Abstract

This research aims to measure the quality of the internet network in Gedung Guntur, which is owned by PT Jasnita Telekomindo and houses a call center tenant. The staff of the call center have complained about the slow internet connection when inputting reports in the CRM system and making phone calls to customers. Therefore, this research is conducted to measure network parameters, such as throughput, delay, and packet loss, by implementing Quality of Service (QoS) on voice and CRM data. The measurement is performed using Axence Net Tools 5 software. The results of the testing show that the bandwidth parameter has a value of 3.086 Kbps, throughput has a value of 1.918 Kbps, delay has a value of 1 ms, and packet loss has a value of 0%. If these test results are compared with the TIPHON standard, the parameters achieve an index of 4, indicating excellent network quality. This research provides a clearer understanding of the quality of the internet network in Gedung Guntur and indicates that the network meets the TIPHON standard. The results of this research can be used as a basis for identifying necessary improvement or enhancement measures to improve the service quality in Gedung Guntur.

Abstract

Various algorithms and machine learning techniques are being applied to improve the efficiency and effectiveness of the process of automatically classifying complaint reports from the public in Indonesia. One machine learning algorithm that has recently gained benchmarks in the state of the art of various problems in machine learning is eXtreme Gradient Boosting (XGBoost). This study aims to develop an extreme gradient boosting model based on term frequency (TFXGBoost) to predict whether a text is classified as a complaint or not a complaint based on the data studied. Based on the experimental results, TFXGBoost achieved 92.79% accuracy with eta / learning rate hyperparameters of 0.5, gamma of 0, and max_depth of 3 and the computation time required to adjust the hyperparameters was 13870.012468 seconds.
