Abstract

The implementation of various policies in poverty alleviation in Indonesia has yielded good results. This condition is reflected by the downward trend in the percentage of poor people who reached a single digit in 2018. However, this has not much-changed the conditions in some of the poorest provinces such as Maluku, East Nusa Tenggara, West Papua, and Papua. This study aims to analyze the effect of Economic Growth, Unemployment Rate, and Human Development Index (HDI) on poverty in the four poorest provinces from 2011 to 2018. The research data sources from Statistics Indonesia (BPS) with the analytical tool used in estimating the panel data regression model is the Fixed Effect Model (FEM). The results show that economic growth and HDI have a negative effect on the poverty. In reverse, the Unemployment Rate has an insignificant effect. Based on the research results, the government advised coordinating with relevant stakeholders in formulating policies to increase welfare and purchasing power, improve the quality of education, and optimize health services in the four poorest provinces.

Abstract

Let  be a graph with the set of points  and the set of sides . The distance from point u to v in  is the length of shortest path from point  to , denoted by . The eccentricity of point  in graph  is the furthest distance from point to each in  denoted by . The point  is the eccentic point of  if . The purpose of this research is determine the eccentricity of the digraph on the gear graph  and determine the eccentricity of the digraph  gear graph using the breadth first search algorithm. The method used is to collect library sources in the form of books other refrences ehich are then used as the basis for conducting this research. Based on the discussion it can be concluded that the sahpe of eccentricity of the digraph on graph  is complete symetry with Graph Theory is the one of the math theory with mathematic knowledge using with ,  and , while for the eccentricity the digraph on the digraph gear  uses  breadth first search algorithm is ,  and .

Abstract

Pengertian B-aljabar telah diperkenalkan oleh J.Neggers dan H.S.Kim di tahun 2002. Selanjutnya, di tahun 2005, W. Waldenziak mendetailkan tentang karakteristik dari B-Subaljabar Normal yang dapat diasumsikan bawah struktur dari B-Aljabar memiliki kemiripan dari struktur yang dimiliki oleh suatu grup. Selanjutnya di tahun 2014, Joemar C. Endam dan Jocelyn P. Vilela mendefinisikan kondisi himpunan yang merupakan hasil kali dari B-Subaljabar dan juga membuktikan teorema Isomorfisma kedua untuk B-Aljabar yang dikenal dengan teorema Diamond. Tulisan ini membahas mengenai sifat tambahan dari Teorema Diamond untuk B-AljabarA B S T R A C TThe concept of B-algebra was introduced by J. Neggers and HSKim in 2002.Furthermore, in 2005, W. Waldenziak detailed the characteristics of B-NormalSubalgebra which can be assumed that the structure of B-Algebra has similarities tothe structure owned by a group and in 2014, Joemar C. Endam and Jocelyn P. Vilelanot only defined set conditions which are the product of B-Subalgebra but also provethe second Isomorphism theorem for B-Algebra which is known as the Diamondtheorem.This paper discusses about the additional nature of the Diamond Theoremfor B-Algebra.

Abstract

In graph theory, drawing a simple graph on the plane might result an intersection of pair of edges that is not intended as a vertex called crossing. The least amount of crossing in any simple drawing of a graph is the crossing number of that graph, 𝑐𝑟(𝐺). Given a graph G and an integer 𝐾, the general problem to proof 𝑐𝑟(𝐺) ≤ 𝐾 is an NP-Complete problem, which means, it is likely intractable. One of the way to proof 𝑐𝑟(𝐺) ≤ 𝐾 is by showing the drawing of graph 𝐺 with 𝐾 number of crossing; doing it with a computer application can be much of help. Therefore, the purpose of our research is to create one using Tkinter of Python. The development of the application is feature driven. The developed features are used to find any simple drawing of graphs on the plane. As the result, the application can proof 𝑐𝑟(𝐾_3,3) ≤ 1, 𝑐𝑟(𝐾_6) ≤ 3, and 𝑐𝑟(𝐾𝐺_5,2) ≤ 2.

Abstract

Graf didefinisikan sebagai pasangan himpunan , yang dalam hal ini  adalah himpunan simpul-simpul (vertices) dan  adalah himpunan sisi (edges). Perkembangan dari Teori Graf dapat dihubungkan dengan cabang ilmu Matematika yang lain seperti Aljabar yang menarik untuk dibahas. Sebuah graf dapat direpresentasikan ke dalam Matriks Laplacian (pengurangan matriks derajat dan matriks ketetanggaan) yang dapat dihitung nilai eigennya. Tujuan penelitian ini adalah untuk membuktikan pada graf terhubung (connected graph) pertidaksamaan , bilangan  adalah derajat Laplacian terbesar ke- pada matriks Laplacian,  merupakan nilai Eigen terbesar ke-  pada matriks Laplacian dan  merupakan derajat terbesar ke-  dari graf terhubung  sehingga berlaku untuk . Penelitian ini dilakukan menggunakan studi pustaka. Hasil penelitian diketahui bahwa  berlaku untuk  pada batasan graf terhubung.

Abstract

Investment is a commitment to place a number of funds in an asset to gain benefits in the future. but there will be unexpected risks in investment such as the covid-19 pandemic. a strategy to minimize the risk is to form a portfolio. This study aims to form an optimal portfolio before and during the covid-19 pandemic on LQ-45 shares along with the proportion of funds for each share obtained using a single index model. The data used are in the form of daily stock closing prices, JCI price, and risk-free interest rates. The results of this research get a combination of six stocks and the proportion of funds for data before covid-19 are BTPS gets 15.61%, MNCN gets 6.69%, EXCL gets 19.89%, CTRA gets 9.81%, ICBP gets 10.62%, BBCA gets 37.38% and four stocks combination and the proportion of funds for data during covid-19 are INCO gets 30.09%, ANTM gets 27.54%, INKP gets 22.81%, KLBF gets 19.56%. INCO, ANTM, INKP, KLBF shares can be considered by investors in making investment decisions during the covid-19 pandemic.
