Abstract

The aim of the research was to make high protein instant tiwul from mocaf which was substituted with jack bean flour and given a food grade commercial thickener to improve its sensory aspect. The study used a randomized block design. The factors studied were germination treatment on jack bean (G), without pre germination (G1) and with pre germination (G2); Proportion of mocaf: jack bean flour : tapioca (w/w) (F), P1 = 75:15:10, P2 = 70:20:10 and P3 = 65:25:10 and Addition of Commercial food grade thickening agent (w/w; % to flour weight) (K), K1 = 0.5%, K2 = 0.75% and K3 = 1.0%. The variables studied were physicochemical properties (moisture content, ash content, formol value, rehydration ability, for the best treatment, protein and fat content were tested) and sensory properties. Data were analyzed by F test (ANOVA) and continued with DMRT (Duncan Multiple Range Test). Based on the effectiveness index test, the best instant tiwul was G2P3K3 (with pre germination; proportion of mocaf-jack bean flour-tapioca w/w 65:25:10; commercial food grade thickening agent 1%). This instant tiwul has a water content of 4.39% wb; protein 7.05%db (6.74%wb), fat 6.39% db (6.11%wb), ash 0.98%db (0.93%wb) and carbohydrates (by difference) 85.54% db (81.78% wb), coefficient rehydration 3,67 and formol value 0,0383 ml NaOH 0,1N/g bk.

Abstract

One of the external obstacles of students is the learning media used by teachers. Learning achievement will be more developed if students actively participate in learning activities. This study aims to improve mathematics learning achievement at line material. The methodology used in this study is an experimental research methodology. The subjects of this study were 7th class students of SMP Negeri 2 Limpung with class VII A as the experimental group and class VII B as the control group. The results showed that the mathematics learning model assisted by Geogebra at line material is effective to be used, this was seen from the completeness of learning outcomes, the influence of reasoning and communication skills to learning achievement with a regression equation = 36,203 + 0,591x and a coefficient of determination is 68.7%. Mathematical learning strategies by Geogebra are also better than learning mathematics without Geogebra. Thus Geogebra-assisted learning on line material can be used as an alternative method of learning in order to add the variety of teaching methods in an effort to train students' reasoning and communication skills and increase student learning outcomes..

Abstract

This article discusses some properties of regular semigroups. These properties are especially concerned with the relation of the regular semigroups to ideals, subsemigroups, groups, idempoten semigroups and invers semigroups. In addition, this paper also discusses the Cartesian product of two regular semigroups. Keywords:ideal, idempoten semigroup, inverse semigroup, regular semigroup, subsemigroup.

Abstract

The specific purpose of this study is to determine the profile of visual representation of students in geometry courses. This research is a qualitative research. The data collection method is done through documentation, observation, learning achievement tests and questionnaires. The results showed that the ability of visual representation of 1st semester students at mathematics education was still low. This is reviewed in the student's ability to answer learning achievement test at geometry courses.

Abstract

Penelitian ini bertujuan untuk mengetahui profil pemahaman konsep matriks pada mata kuliah Struktur Aljabar. Penelitian ini merupakan penelitian kualitatif. Metode pengambilan data dilakukan melalui dokumentasi, observasi, tes hasil belajar. Hasil penelitian menunjukkan bahwa pemahaman konsep matriks pada mata kuliah Struktur Aljabar masih rendah. Hal tersebut ditinjau pada kemampuan mahasiswa untuk menjawab soal tes hasil belajar mata kuliah Struktur Aljabar. Dengan demikian diperlukan adanya penekanan khusus mengenai konsep matriks sebelum mahasiswa mengambil mata kuliah Struktur Aljabar.Kata kunci: pemahaman, matriks, struktur aljabar.

Abstract

Pada makalah ini dibahas tentang penggunaan dekomposisi rank untuk mengonstruksi invers Moore-Penrose pada matriks atas aljabar max-plus tersimetri. Penentuan eksistensi dekomposisi rank dilakukan dengan memanfaatkan suatu fungsi yang mengkorespondensikan aljabar max-plus tersimetri dengan aljabar konvensional. Selanjutnya, dengan memanfaatkan eksistensi invers setimbang, hasil dekomposisi rank ini digunakan untuk mengonstruksi bentuk invers Moore-Penrose dari matriks. Hasil yang diperoleh adalah bentuk invers Moore-Penrose dari suatu matriks atas aljabar max-plus tersimetri berdasarkan dekomposisi rank. Hasil ini berpotensi dapat dimanfaatkan untuk menentukan solusi dari sistem kesetimbangan linier atas aljabar max-plus tersimetri.
