ANALISIS SIRKULASI UDARA PADA TANAMAN KOPI BERDASARKAN POLA TANAM GRAF PRISMA DAN TINGKAT KEMIRINGAN BATANG MENGGUNAKAN METODE VOLUME HINGGA
Get PDFAbstract. Coffee bean is one of the superior agricultural products in Indonesia. One of the factors that affect the productivity is the cropping pattern of coffee plants. A well organized cropping pattern will make a well organized air circulation which affects the productivity of coffee beans. In this research, a model of air circulation is built based on prism graph for the cropping pattern and solved by using Finite Volume Method (FVM). The model simulation process is done by using MATLAB and FLUENT software. The model is built according to the slope of stem and the temperature of coffee plantation. The temporary result of the research shows that prism graph cropping pattern results good air circulation and also gives good effect to the air circulation around the coffee plantation. The same thing happens to the effect of the slope of stem, the more upright the coffee plant is, the better air circulation and vice versa.
Key Words : Coffee plants, air circulation, prism graph, Finite Volume Method (FVM

Get PDFAbstract. One of compulsory subject taught in SMPLB-A is mathematic. Geometry is known as part of mathematic. SMPLB-A student also learn rectangle and square but there is only few media and worksheet that can make them learn independently. This research is developing a worksheet based on four-D models. The developed Braille worksheet have to satisfy validation criteria, effectiveness criteria and practicality criteria. After analize data from research process, obtained that validation average value (Va) is 3,77 which means this Braille worksheet is valid. The effectiveness criteria is obtained from student’s and teacher’s activity which indicate that the activity is satisfy ideal time, so the Braille worksheet is effective. For practicality criteria, we use questionnaire to student. From the questionnaire, value percentage reach 86,25% which indicates that the Braille worksheet at good category and satisfy the practicality criteria. After Braille worksheet fullfill the validation, practicality and efectifeness criteria, this worksheet can be disseminated to school. Key Words: blind student, Braille worksheet, 4-D models

Get PDFAbstract. An  (a, d)-edge-antimagic  total  labeling  of G  is a  one-to-one  mapping taking the vertices and edges onto {1, 2, 3, . . . , p + q} Such that the edge-weights w(uv)  = (u)+(v)+(uv), uv ∈ E(G)  form an arithmetic sequence {a, a+d, a+2d, . . . , a+ (q − 1)d}, where first term  a > 0 and  common  difference d ≥ 0.  Such a graph G is called super if the smallest possible labels appear on the vertices.  In this paper we will study a super edge-antimagic total labelings properties of connective Swn graph.  The result shows that a connected Silkworm graph admit a super (a, d)-edge antimagic total labeling for d = 0, 1, 2. It can be concluded that the result of this research has covered all the feasible n, d.  Key Words: (a, d)-edge-antimagic total labeling, super (a, d)-edge-antimagic total labeling, Silkworm graph
ANALISIS PROSES BERPIKIR SISWA DALAM PEMECAHAN MASALAH TERBUKA BERBASIS POLYA SUB POKOK BAHASAN TABUNG KELAS IX SMP NEGERI 7 JEMBER
Get PDFAbstract. The research aims to describe the students’ thinking process of 9th grade of Junior High School in solving the open problem according to their capability in solving problem based on Polya’s solution step. Data analysis is done based on written test and interview techniques. The subject of research is students of IXA class at SMPN 7 Jember in odd semester academic year 2013-2014. The data of research are obtained by validation sheet, written test, and interview techniques. Students experience disequilibrium when they don’t understand about the qestion’s sentence and when she can’t determine the ways to solve the problem, also when she can’t determine the ways to check the result that has already gotten when she does the plans. Students experience assimilation when they can mention what is known and what is asked  from the problems immediately without reck of true or false, also when  they can determine the ways to solve the problems and when they are doing the computations. Students experience accomodation when they are quiet and confuse before they can determine the problem’s condition, also when she is doing the computation and when she is quite before she can determine the ways to solve the problem. Students experience assimilation and accomodation to reach the equilibrium phase. Key Words: thinking process, open problem, and Polya’s solution step

ANALISIS SIRKULASI UDARA PADA TANAMAN KOPI BERDASARKAN TINGKAT KEKASARAN TUMBUHAN DAN POLA TANAM GRAF TANGGA PERMATA MENGGUNAKAN METODE VOLUME HINGGA
Get PDFAbstract. Coffee beans are one of Indonesian main export commodities. It can be seen from the amount of coffee exported to other countries, especially Europe. However, the vast area of coffee plantation does not make the productivity of the coffee beans become maximum. There are several factors which influence this condition. One of them is the cropping pattern of coffee plant and the air circulation that affect the pollination process of coffee flower. In this research, an air condition models was designed to solve the problem by employing Volume Hingga method. The models were designed based on the level of plant roughness, distance between coffee plants, and the cropping pattern of coffee (Diamond Ladder Graph). The results of the research is the mathematical models that influenced the level of plant roughness and the cropping pattern of coffee with angle. The symbol of plant roughness in this model is . Coefficient is limited at 0 until 1 (0< <1). The high value of plant roughness coefficient shows the high level of plant roughness. Key Words: coffee plant, air circulation, level of plant roughness, Volume Hingga Method, Diamond Ladder Graph
