In principle, the development of information technology helps people to interact with others or surroundings. Further, with the change in technology providing simpler, more collaborative and more transparent communication and computer system to many people, it is also important for children to have skill in computer that they can learn effectively. Counting skill has been introduced to kindergarten, creating various counting methods to help teachers and parents to teach it. However, the methods will not be effective without the use of application system in a learning process because every student is unique that he needs different way of learning. A more decisive matter is the parent’s understanding about how the children learn and what their way of learning is. Based on the description above, it is necessary to provide a learning media in the form of application which can draw children’s interest and facilitate children’s learning process with a play-based learning concept applied beyond the formal learning time in which this media can be flexibly used. This research is conducted by applying android-based counting software at kindergarten in Jagakarsa.

AbstrakUniversitas Nasional merupakan salah satu perguruan tinggi swasta yang berada di Jakarta Selatan yang setiap tahun selalu memberikan program beasiswa kepada mahasiswa yang pantas mendapatkan beasiswa. Beasiswa diberikan sebagai pendukung atau apresiasi terhadap mahasiswa yang berprestasi dan yang kurang mampu. Pada cara sederhana, nilai dari setiap siswa dan bobot kriteria kurang diperhatikan, sehingga hasil yang diperoleh kurang mewakili dari nilai tersebut. Proses seleksi penerimaan beasiswa memerlukan suatu sistem terkomputerisasi yang dapat menunjang pengambilan keputusan. Pada penelitian ini dibangun sistem penunjang keputusan menggunakan logika fuzzy dengan metode mamdani. Penerapan metode fuzzy mamdani diterapkan pada sistem yang dibuat dengan bantuan tool box fuzzy program Matlab. Terdapat beberapa kriteria yang menjadi dasar pengambilan keputusan untuk seleksi penerimaan beasiswa, yaitu IPK, Semester, Penghasilan Orang Tua, Tunjangan Orang Tua, Usia, dan Piagam. Hasil seleksi yang diberikan kepada mahasiswa berupa jenis beasiswa yang dapat diterima oleh mahasiswa yang bersangkutan. Penilaian dilakukan dengan memberikan nilai bobot untuk setiap variabel dari masing-masing kriteria. Proses seleksi dengan metode mamdani menghasilkan mahasiswa yang pantas mendapatkan beasiswa atau tidak dan merekomendasikan jenis beasiswa yang dapat diperoleh mahasiswa untuk mendapatkan beasiswa.Kata Kunci : SPK, Fuzzy MADM, Mamdani, Matlab AbstractUniversitas Nasional is one of the private universities located in South Jakarta. It offers scholarship programs every year to students who deserve a scholarship. Scholarships are awarded as a support or appreciation for outstanding and underprivileged students. In a traditional way, the scores of each student and the criterion's weight just get little attention, causing the obtained results does not fully represent the scores. The selection process of scholarship award requires a computerized system that can support the decision-making. In this study, a decision support system is built using fuzzy logic with mamdani method. The fuzzy mamdani method is applied to the system created with the help of the Matlab program fuzzy tool box. There are some criteria used as the basis for decision-making for selection of scholarship award, i.e. GPA, Semester, Parent's Income, Parent’s Allowance, Age, and Certificate. The results of the selection given to the students are in the form of scholarships that can be won by the related students. The assessment is conducted by scoring each variable of each criterion. The selection process using the mamdani method shows whether the students deserve a scholarship or not and recommends the type of scholarships that can be earned by the students obtaining the scholarships.Keywords : SPK, Fuzzy MADM, Mamdani, Matlab

Stock is one of financial assets popularly invested in the present time. In spite of its unstable movement, stock price can be predicted for certain period of time to estimate the profit that will be made. The owned stocks can be systematically arranged to produce a maximum profit with minimal risks through portfolio. Portfolio can be arranged by imposing various constraints, such as sector capitalization. With this constraint, portfolio does not create a proportion for each stock, but for every sector containing various stocks. If implemented, the investor may be interested in investing their capital into the stocks that have the high value in the capital market. By investing in various stocks, investors can minimize the risks provided one of the chosen sectors suffers loss. Optimization with this constraint is a non-linear optimization problem with integer and real numbers with the help of Particle Swarm Optimization method. The optimization results in this article show the consecutive weight of five sectors of LQ45 stocks are 0,353; 0,2465; 0,222; 0,1164; 0,0955 with the risk of 0,0030.
