Motion capture system is a promising research area but the availability of the state-of-the-art literature review on this topic is limited. This research provides a comprehensive literature review for motion capture systems with Kalman filtering algorithms. The summarized state-of-the-art literature review of motion capturing system is being analyzed considering the advantages and the disadvantages of motion capture systems using Kalman filtering algorithm. Afterwards, the human body incorporating noises is represented by system of equations where the system states are unknown. The Kalman filter is adopted to estimate the human body orientations. Simulation results show that the proposed algorithm can be used to track human body orientation accurately.
Agriculture is known as one of the main factor for a growth of a country. Paddy plantation is the most widely planted crop in Malaysia. The rice produced is the main food source to Malaysian's people and source of income to this country as well. However, a disease known as Brown Spot (BS) attacks the paddy plants and threats their quality. This disease caused by bipolar fungus, which represent by the development of an oval, dark brown to purplish-brown spot on leaf. This disease observed as among the hazardous disease that may result in degradation of paddy production. Brown Spot disease could spread through airborne spores from plant to plant on the field. In this research, a system that could help people, especially farmers, to detect the disease at early stage is developed. The real image capture at paddy field is processed in the MATLAB software with image enhancement, background removal as well as binary and RGB image masking process. To determine the Brown Spot area, pixel intensity between the infected and noninfected areas is calculated. The severity level table developed by Horsfall and Heuberger is then used as reference to classify the severity level of Brown Spot disease. A GUI is created to detect the Brown Spot disease automatically. From the study conducted, the accuracy of Brown Spot detection is approximately 89% accurate compared to manual evaluation by plant pathology.
ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan pembelajaran kontekstual melalui kegiatan mencetak gambar terhadap kemampuan motorik halus pada anak kelompok B di Tk Widya Kumara Sari Denpasar tahun ajaran 2017/2018. Penelititian ini merupakan penelitian pra eksperimen one group pretest-posttest design dan pendekatan pembelajaran kontekstual. Populasi dalam penelitian ini adalah kelompok B TK Widya Kumara Sari yang terdiri dari yang berjumlah 28 orang. Sampel diambil dengan teknik sampling jenuh data kemampuan motorik halus diperoleh dengan metode non tes, selanjutnya dianalisis menggunakan rumus uji-t dependent t test. Berdasarkan hasil analisis yang dilakukan dengan menggunakan uji-t diperoleh thitung = 88,9 > ttabel = 2,00, dengan Taraf signifikansi 5% dan db = 27, sehingga H0 ditolak dan Ha diterima, yang berarti terdapat perbedaan yang signifikan terhadap kemampuan motorik halus pada anak kelompok B melalui kegiatan mencetak gambar di Tk Widya Kumara Sari Denpasar Tahun Ajaran 2017/2018. Rerata nilai kemampuan motorik halus anak yang dibelajarkan melalui pendekatan pembelajaran kontekstual pada anak Tk sebagai kelompok posttest adalah 81,26. Dengan demikian, dapat disimpulkan bahwa terdapat pengaruh pendekatan pembelajaran kontekstual melalui kegiatan mencetak gambar terhadap kemampuan motorik halus pada anak kelompok b di tk widya kumara sari denpasar tahun ajaran 2017/2018. Berdasarkan hasil tersebut dapat disarankan kepada guru untuk lebih mengembangkan inovasi dalam menerapkan pendekatan pembelajaran kontekstual melalui kegiatan mencetak gambar. Kata Kunci : Pendekatan Pembelajaran Kontekstual, Kegiatan Mencetak Gambar , Kemampuan Motorik Halus Abstract This research aims to know the influence of contextual learning approach through print pictures fine motor abilities against the children's Group B in kindergarten Widya Kumara Sari Denpasar 2017/2018 school year. Penelititian this is a pre research experiments one group pretest – posttest design and contextual learning approach. The population in this research is the Group B TK Widya Kumara Sari which comprises of 28 people. Samples taken with the technique of sampling data in saturated fine motor ability obtained with methods, the next test is analyzed using t-test formula dependent t test. Based on the results of the analysis done using the t-test is obtained thitung = 88.9 ttabel > = 2.00, with significance Level 5% and db = 27, so that H0 is rejected and accepted Ha, which means there is a significant difference towards the motor ability smooth on Group B activities through print pictures in kindergarten Widya Kumara Sari Denpasar 2017/2018 school year. The average value of fine motor ability of children who dibelajarkan through contextual learning approach in kindergarten as a group posttest is 81.26. Thus, it can be concluded that there is an influence of contextual learning approach through print pictures fine motor abilities against the children's group b in kindergarten widya kumara sari denpasar 2017/2018 school year. Based on those results can be recommended to teachers to better develop innovation in applying a contextual approach to learning through activities of the print image. keyword : Key words: Contextual Learning Approaches, activities to print pictures, fine motor Ability
