Abstract

Health is an investment to support economic development and has an important role in efforts to reduce poverty and improve the quality of human resources. One of the diseases that often become serious problem in health sector that is Dengue Hemorrhagic Fever (DHF). In Indonesia, many mosquitoes cause dangerous DHF such as Aedes aegypti, Aedes albopictus, Aedes africanus, anopheles and others. In this study, we analyzed and applied SIR (Susceptible, Infection, Recovered) mathematical models and their interpolation to determine whether a contagious disease (DHF) can become endemic or not. Therefore, in this study aimed to determine the a special form of model of SIR to analyze the spread of DHF in Maluku Province and the stability analysis of this model and also interpolating the data of DHF transmission in Maluku Province. Furthermore, it can be obtained the characteristics of equilibrium point of each sub population. Based on the research conducted it can be concluded that from the entire population of Maluku Province is 1.686.469 vulnerable people infected with DHF and endemic disease with the basic reproduction value is 3,44.

Abstract

The main goal of every company in business is the optimal profit. Challenges that often faced by companies in achieving maximum profit is the difficulty of combining every available resources of the company. The purpose of this study was to determine the maximum profit that can be obtained by Ls Garment using the simplex method and determine the impact of the changes that occur in the objective function coefficients and constants right side constraints to the optimal solution. Based on the results of the application method used, it was obtained maximum profit of Rp. 1.893.184,00 per day with the amount of Dress Payung, Celana Aladdin XL, Celana Aladdin XXL, Celana Aladdin ¾, Dress Kerut, and Daster Haji respectively are 34, 60, 68, 96, 26, and 26 pieces. Profit remain in optimal condition if the change of coefficients value at the objective function is less than or equal to the coefficient of the objective function at the initial model.

Abstract: Sidoarjo is one of the districts located in East Java that has developed rapidly. The remarkable progress can be achieved due to several potentials had by its people, for instance, industries, trades, small and medium businesses. Therefore, this research aims to find out the information regarding dominating factors had by the Sidoarjo using data mining. The result shows that Keboansikep, Sawotratap, Tebel, Keboananom, Gedangan, Keboguyang, Ketajen, Sidomulyo, Terik, Ponokawan, Sedengan Mijen, and Barengkrajan villages are the most potential villages in Sidoarjo. Based on the classification method, it is found that the villages of Keboansikep, Sawotratap, Tebel, Keboananom, Gedangan, and Ketajen (Gedangan District) have local potential in the form of agricultural factors such as rice and secondary crops. All residences in Keboguyang Village (Jabon District) already have an IMB. Meanwhile, the villages of Sidomulyo, Terik, Ponokawan, Sedengan Mijen, and Barengkrajan (Krian District) have high early childhood education factors such as kindergarten students, kindergarten teachers, and kindergarten schools Keywords: Data Mining, Local Potential, Biplot analysis

Abstract

Quality of learning mathematics is supported by the availability of qualified learning facilities for students, for example worksheet. This study aims to describe how to develop and produce student’s worksheet (LKS) of flat side space, based on Problem-Based Learning (PBL) which is valid and practical. This study is research and development which is held in SMP N 2 Pengasih, Yogyakarta using Thiagarajan development model. The result of study is obtained development process of LKS comprising defining phase, designing phase, developing phase that starts from expert validation, revision, readability test, product revision, field test, and ends with the disseminating phase. The result of expert validation shows that LKS is valid in very good category. LKS practically gets very good category from tehacher assessment. The result of students assessment shows that 43,75% students can use LKS in very good category and 56,25% students can use LKS in good category.

Abstract

Dalam statistika salah satu ukuran untuk melihat ketergantungan antara dua peubah adalah dengan menggunakan koefisien korelasi. Namun, dalam banyak aplikasi finansial terutama manajemen risiko finansial penggunaan korelasi kadang tidaklah tepat. Salah satu contoh kelemahan korelasi adalah ketidakmampuan korelasi untuk menangkap hubungan nonlinear antara dua peubah. Selain itu, sifat-sifat umum korelasi yang dikenal biasanya hanya berlaku pada distribusi eliptik. Untuk itu diperlukan suatu metode untuk mengeksplorasi struktur ketergantungan antarpeubah tersebut. Metode ini adalah kopula. Tujuan artikel ini adalah memberikan tutorial singkat tentang kopula dan estimasinya.

Abstract

Daftar Pemilih Tetap (DPT) ganda merupakan masalah klasik yang terus-menerus terjadi saat Negara Indonesia akan menyelenggarakan pemilihan umum, baik ditingkat kabupaten, propinsi, maupun nasional. Keadaan ini akan sangat berbahaya bagi kemajuan demokrasi di Indonesia karena adanya DPT ganda ini dapat mendeligitimasi hasil pemilihan umum yang telah dilaksanakan. Metode yang digunakan untuk mengembangkan filter DPT ganda adalah gabungan dari algoritme longest common suffix (LCS) sebagai mesin filter DPT, algoritme quicksort dan priority queue sebagai struktur data untuk menyimpan data DPT dan metode penyajian data DPT setelah proses filter. Data yang digunakan adalah data DPT provinsi Bali tahun 2019 yang didapatkan dari KPUD seluruh kabupaten di Bali. Prototipe awal filter DPT mampu untuk mengeliminasi data-data pemilih yang dicurigai ganda dengan tingkat kemiripan antar data adalah 95%. Tetapi masih dapat beberapa kesalahan dalam proses filter ini yang disebabkan oleh tidak lengkapnya data yaitu enam angka terakhir dari NIK diganti dengan tanda *, serta tahun lahir juga diganti dengan tanda *.

Abstract

The use of worksheets in Excel is one of the tools for learning in solving the mathematical problems. At generaly the solution of mathematical problem ussually is solved by the soft ware aplication, that sure used high level programming languages like FORTRAN, BASIC, C++, MATLAB, etc. However the use of worksheet in Excel rather more familiar than using the software aplication for the students. It is caused the students must be able to know how to write the code program that obtained product the listing program. One of the most problematic on civil engineering is about concrete beam structure deflection. The mathematical analysis simple beam structure deflection is presented by the ordinary differential equation second order non linier and the other name it’s called poisson equation. The aim of this article for : (1) To give the learning assistance to the student when they aren’t use the soft ware program and beside to rise creation the application spreadsheet as tool for numerical solution by finite difference method on simple beam deflection. (2) To evaluate the error result comparation of numeric solution and analytic solution.(3)To give the understanding about numerical method that accordance with simple beam deflection problem on civil engineering education and mathematical education. Keywords: Fungsi Internal EXCEL, Metode Beda Hingga. Persamaan Garis Elastika.

Abstract

The aim of this research is to know factors having an influence by significant to Entrepreneurship Intention of students in Faculty of Mathematics and Natural Sciences of Sriwijaya University. There used a Structural Equation Models (SEM) analysis method, because variables in this research in the form of laten variable and causal relationship between a set of variables nor modestly, there is direct and indirectly relationship. The result show that family environment give a part important in forming Entrepreneurship intention student, and so Personal attitude give biggest direct influence to Entrepreneurship Intention of student equal to 0,52 with t-test statistical value equal to 6,82.
