Abstract

Constructive Back Propagation Neural Network (CBPNN) is a kind of back propagation neural network trained with constructive algorithm. Training of CBPNN is mainly conducted by developing the network’s architecture which commonly done by adding a number of new neuron units on learning process. Training of the network usually implements fixed method to develop its structure gradually by adding new units constantly. Although this method is simple and able to create an adaptive network for data pattern complexity, but it is wasteful and inefficient for computing. New unit addition affects directly to the computational load of training, speed of convergence, and structure of the final neural network. While increases training load significantly, excessive addition of units also tends to generate a large size of final network. Moreover, addition pattern with small unit number tends to drop off the adaptability of the network and extends time of training. Therefore, there is important to design an adaptive structure development pattern for CBPNN in order to minimize computing load of training. This study proposes Fuzzy Logic (FL) algorithm to manage and develop structure of CBPNN. FL method was implemented on two models of CBPNN, i.e. designed with one and two hidden layers, used to recognize aroma patterns on an electronic nose system. The results showed that this method is effective to be applied due to its capability to minimize time of training, to reduce load of computational learning, and generate small size of network.

Abstract

Abstrak Pada ilmu pengetahuan sosial kajian persoalan-persoalan kehidupan sosial kemasyarakatan yang bersifat praktis sangat berguna bagi siswa sekolah dasar untuk hidup dan kehidupannya masa kini dan masa yang akan datang. Dengan harapan siswa ini nantinya dapat menyadari dan memahami bahwa dia tidak hidup sendirian, tetapi hidup di lingkungan yang luas, jika ingin hidup yang layak. Masalah berikutnya terkait dengan pemilihan dan pendekatan pembelajaran, yang belum banyak menimbulkan keaktifan dan kreatifitas siswa. Hal ini karena masih sering menggunakan pendekatan konvensional, yang pembelajaranya terpusat pada guru, sehingga siswanya menjadi pasif. Jika pembelajarannya dapat mengaktifkan siswa, maka akan menarik dan materi yang banyak tadi bisa secara cepat diserap oleh siswa. Karena mereka antuas, mau belajar dengan sungguh-sungguh. Berangkat dari masalah di atas maka kami tertarik untuk menerapkan model pembelajaran kontekstual yang dipandang dapat membantu siswa aktif dalam kegiatan belajar dan mengajar. Adapun tujuan dalam penelitian ini adalah untuk mengetahui bagaimana pengaruh pemebelajaran kontekstual terhadap prestasi belajar llmu Pengetahuan Sosial. Untuk mengetahui adanya pengaruh minat belajar siswa terhadap prestasi belajar llmu Pengetahuan Sosial. Untuk mengetahui adanya pengaruh pembelajaran kontekstual dan minat belajar siswa secara secara simulltan terhadap prestasi belajar siswa kelas IV SDN lumbang I Kecamatan Lumbang Kabupaten Pasuruan tahun pelajaran 2016-2017.Metode yang digunakan dalam penelitian ini adalah metode kuantitatif yang berlandaskan pada filsafat positivisme, digunakan untuk meneliti pada populasi atau sampel tertentu, pengumpulan data menggunakan instrumen penelitian, analisis data bersifat kuantitatif/statistik, dengan tujuan untuk menguji hipotesis yang telah ditetapkan. Hasil penelitian menunjukkan adanya pengaruh pembelajaran kontekstual dan minat belajar siswa secara simultan terhadap prestasi belajar siswa kelas IV SDN lumbang I Kecamatan Lumbang Kabupaten Pasuruan. Persepsi siswa tentang model pembelajaran kontekstual mempunyai sumbangan yang efektif lebih besar daripada minat belajar siswa terhadap prestasi belajar pada mata pelajaran IPS terpadu meskipun belum secara maksimal sepenuhnya. Kata Kunci: Pembelajaran Kontestual, Minat belajar Siswa dan Prestasi Belajar Siswa Abstract The study "Effects of Contextual Learning Implementation and Interest Student Learning Achievement Terhahadap Science Class V SDN I Sub Lumbang Lumbang Pasuruan in the academic year 2016-2017." In social science study of the problems of social life that is practically very useful for school students basis for life and the life of the present and the future. With hope these students will be able to realize and understand that she does not live alone, but living in a spacious environment, if you want a decent life. The next issue related to the selection and learning approach, which has not generated a lot of activity and creativity of students. This is because they often use the conventional approach, which pembelajaranya centered on the teacher, so that students become passive. If learning can enable students, it will be interesting and a lot of material that had to be quickly absorbed by the students. Because they antuas, willing to learn in earnest. Departing from the above problems then we are interested to apply contextual learning model which is seen to help students actively in learning and teaching activities. The purpose of this study was to determine how the contextual pemebelajaran influence on the learning achievement of Social Sciences. To determine the influence of student interest towards learning achievement of Social Sciences. To determine the influence of contextual learning and students learning interest in simulltan on student achievement grade IV SDN I Sub Lumbang Lumbang Pasuruan in the academic year 2016-2017. The method used in this research is a quantitative method that is based on the philosophy of positivism, is used to examine the population or a particular sample, data collection using research instruments, quantitative data analysis / statistics, with the aim to test the hypothesis that has been set. The results showed the influence of contextual learning and student interest simultaneously on student achievement grade IV SDN I Sub Lumbang Lumbang Pasuruan. Students perceptions about contextual learning model has an effective contribution is greater than the interest of student learning to the student achievement in social studies though not optimally integrated fully.

Abstract

The world demand of raw-silk provides a great opportunity to the development of raw-silk production in Yogyakarta. Recently, only 21% of the overall world demand of raw-silk is fulfilled, whereas Indonesia contributes only 0.1% per year. The main problem is the lack of quality of raw-silk. The optimum growth of silkworm depends on micro environments, i.e. temperature, humidity, aeration, and light intensity. The research aimed at designing an automated “on/off” control technology in the silkworm rearing environmental monitoring in the farming system, while the expected result was high-grade quality of cocoon. In the research, two different conditions of silkworm growing environments were compared, i.e. controlled environment (in the rearing box) and uncontrolled environment. The result indicated that there was increase in  the quality of cocoon. Test of cocoons in laboratory showed that the average thickness of cocoons in controlled rearing environment and in rearing environment was 0.033 cm and 0.029 cm, respectively. The percentage of cocoons in controlled rearing environment was higher than cocoons in normal environment.

Abstract

The real data support the “seriousness” of the serious game and give more authentic situations, which can make players feel immersed in scenarios, and gain a real experience. Therefore, the modeler must be able to recognize whether a model reflects reality to identify and deal with divergences between theory and data. In this paper, we present a model for design a basis of immersive in serious games. The studied case is the tillage using a moldboard plow, by taking real data through an experiment use a device called soil bin. It aims to determine the effect of angle, depth, and speed on the soil porosity; by comparing the value of the smallest error using the polynomial function of the use of different orders. The result of an average smallest error with the polynomial approach is 1.10E-07 in the 3rd order, closer to the experimental value. Therefore, the model can be used for designing immersive serious game.
