Abstract

Despite its importance, there are still many problems encountered in the learning of the topic of reflection in school. One of the solutions for these problems is the implementation of learning approaches that fit the modern curricula and the development of good quality instructional materials. Therefore, the aim of this study was to describe the quality of investigative instructional material with computer assisted instruction for the topic of reflection in Grade VII. The result of the analysis suggested that the investigative instructional material for the topic of reflection in Grade 7 is of good quality because it fulfills the following criteria: (1) the teacher was capable to manage the lesson well, (2) the students were actively involved during the lesson, (3) the students gave positive response to the instructional material, (4) the achievement test is valid, reliable, and sensitive; and (5) the validator claimed that the developed instructional material is valid.

Abstract

Penelitian ini merupakan penelitian deskriptif kualitatif yang bertujuan untuk mendeskripsikan kemampuan berpikir matematis siswa kelas XI Madrasah Aliyah (MA) Salafiyah Syafi?iyah Mojokerto dalam memecahkan masalah matematika ditinjau dari program study. Program study yang dimaksud dalam penelitian ini adalah program study regular dan tahfidz. Pemilihan subjek penelitian dilaksanakan berdasarkan teknik pengambilan purposive sampling. Pengelompokan subjek penelitian ini berdasarkan pada kemampuan matematika siswa. Tingkat kemampuan matematika siswa dalam penelitian ini dikategorikan menjadi 3 yaitu kemampuan matematika tinggi, sedang, dan rendah. Selanjutnya dari hasil pengelompokan kemampuan matematika siswa, setiap kelompok tingkat kemampuan matematika diambil satu dari setiap kelasnya. Instrumen yang digunakan untuk mengumpulkan data adalah tes pemecahan masalah dan pedoman wawancara. Hasil penelitian menunjukan bahwa terdapat perbedaan kemampuan berpikir matematis pada siswa program study regular dan tahfidz. Siswa kelas XI MIPA 1 program study tahfidz memiliki kemampuan berpikir matematis dalam memecahkan masalah matematika dapat dibedakan menjadi dua yaitu tinggi dan sedang. Kemampuan berpikir matematis yang tinggi dapat dipenuhi oleh subjek ST-T dan ST-S, dan kemampuan berpikir matematis yang sedang dipenuhi oleh subjek ST-R. Sedangkan kemampuan berpikir matematis siswa kelas XI MIPA 2 program study regular dalam memecahkan masalah matematika dapat dibedakan menjadi tiga sesuai dengan kemampuan matematika yang dimiliki oleh setiap subjek.

Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana kemampuan pemecahan masalah matematika siswa SMP berdasarkan langkah Polya. Metode yang digunakan adalah metode kualitatif dengan teknik analisis data triangulasi. Dari penelitian tersebut dapat dilihat bahwa siswa mampu memecahkan masalah matematika. Hal tersebut tampak dari kemampuan siswa dalam: (1) menentukan hal-hal yang diketahui dan yang ditanyakan secara lengkap. Selain itu siswa juga mampu memahami hubungan antar informasi yang diberikan. Sehingga dapat dikatakan bahwa siswa mampu memahami masalah. (2) menyusun suatu permisalan dan menyusun model matematika, sehingga dapat dikatakan bahwa siswa mampu menyusun rencana penyelesaian. (3) menyelesaikan model matematika dengan tepat, mampu mencari hasil akhir dari soal tersebut  dan mampu melakukan operasi hitung dengan tepat. Sehingga dapat dikatakan bahwa siswa mampu melaksanakan rencana penyelesaian. (4) mengecek penyelesaian soal tersebut baik langkah-langkahnya maupun perhitungannya serta menyusun kesimpulan. Sehingga dapat dikatakan bahwa siswa mampu mengecek kembali. Dari keterangan di atas dapat disimpulkan bahwa siswa mampu memecahkan masalah matematika berdasarkan langkah Polya.   Kata kunci: masalah matematika, kemampuan pemecahan masalah matematika, langkah Polya.

Abstract

. Linear Fractional Programming (LFP) problem is general form of Linear Programming (LP) problem. LFP problem arise when there is requirement to optimalize the efficiency of some activity. The efficiency related to the most productive way to use the scarce resources. Many method have been published to solve LFP problem. In this final project explained two methods, Charnes-Cooper’s method and Hasan-Acharjee’s method. The both method use a transformation to change LFP problem become LP problem, then solved by simplex method. Finally, it is concluded that there is comparison that the Charnes-Cooper’s method can be applied in all of LFP form which the set of feasible solutions is non-empty and bounded, but the formed LP becoming more complex than Hasan-Acharjee’s method. Hasan-Acharjee’s method cannot be used when the constanta of denominator in objective function is zero.

Abstract

Economic Production Quantity (EPQ) used to determined policy and oversee inventory levels. This article discussed on EPQ models for  planed of product with partial backordered and its component. The final product is assummed have m component and coordinated planning used to coordinate component of product and final product which is the components used for basic EPQ models and for final product planned using partial backorder EPQ. Numerical simulation given based  data on UD. Adi Mulya.

Abstract

The aims of Economic Production Quantity models are for manage the production schedule and product inventory. The first Economic Production Quantity model developed by E.W Taft on 1918. Taft make some asumption such as daily demand rate constant, daily production rate constant, not stockout allowed, single item product and daily production rate are more than daily demand rate. On the process of delivery product,  there is not transportation cost. Pasandideh dan Niaki on 2010 was constructed an Economic Production Quantity models with discrete delivery order. In this research we discussed the Economic Production Quantity model which products delivered by multiple palet system and with transportation cost.

Abstract

This paper discussed about the construction of Cantor middle third set which is formed from unit interval . To construct the Cantor set, take a line and remove the middle third and remain two line segments. This Process is repeated infinite number of times. This process produces some interesting properties on Cantor middle third set, such as has uncountable many elements, contains no intervals, and is compact, perfect, and nowhere dense. By using Hausdorff dimension and self similar set, it discussed the dimension of Cantor middle third set which is a unique positive number

Abstract

Mathematical learning needs to be given to all students starting from elementary school, so that students practice how to think in drawing conclusions and be able to express their opinions with the beliefs and honesty that comes from someone. But when learning mathematics the problem that often arises is a lack of motivation. Baroody (1993) says that reasoning is an important tool in learning mathematics to produce ideas so students can understand mathematical concepts correctly. Efforts made by teachers to improve thinking skills and motivation in learning mathematics are through the Adobe Flash CS 5.0 game which is expected to provide new and enjoyable experiences for teachers and students. In addition to more varied learning, students can be motivated to learn and enjoy what they learn.
