Di sekolah-sekolah kebanyakan guru yang lebih aktif daripada siswa, padaha! aktivitas belajar siswa berhubungan dengan hasil belajarnya, dapat membuat siswa lebih kreatif dan dapat mengingat materi lebih lama. Untuk itu perlu dicari metode pembelajaran yang lebih mengaktifkan siswa belajar. Metode IMPROVE merupakan metode yang di dalamnya memberikan kesempatan kepada siswa untuk lebih aktif belajar dan lebih memberikan kesempatan kepada siswa untuk berkomunikasi matematik. Dengan demikian penelitian ini bertujuan untuk menelaah apakah pemahaman matematik dan kemampuan komunikasi matematik siswa yang menggunakan metode IMPROVE lebih baik daripada yang menggunakan cara biasa. Untuk mengarah kepada tujuan yang ingin dicapai tersebut penelitian ini menelaah : (a) pemahaman matematik siswa sebelum dan sesudah pembelajaran dengan metode IMPROVE dan cara biasa; (b) kemampuan komunikasi matematik siswa sebelum dan sesudah pembelajaran dengan metode IMPROVE dan cara biasa; (c) kaitan (assosiasi) antara pemahaman matematik siswa yang menggunakan metode IMPROVE dan cara biasa; (d) aktivitas siswa selama pembelajaran berlangsung;(e)sikap siswa terhadap pembelajaran dengan metode IMPROVE; (0 kesulitan-kesulitan yang ditemui selama penerapan pembelajaran dengan metode IMPROVE. Penelitian ini merupakan studi eksperimen di SLTP Negeri I Cimahi dengan disain penelitian Pre-test Post test Control Group design. Subjek Populasi seluruh siswa SLTP dengan mengambil sampel 2 kelas II SLTP Negeri I Cimahi secara acak dari kelas paralci yang tersedia. Pengumpulan data dilakukan dengan cara ; (1) memberikan tes pemahaman matematik dan komunikasi matematik pada pokok bahasan relasi,pemetaan dan grafik, kuadrat dan akar kuadrat suatu bilangan, serta teorema pythagoras; (2) memberikan angket skala sikap kepada siswa; (3) mengobservasi aktivitas belajar siswa.Untuk melihat adanya perbedaan pemahaman matematik dan kemampuan komunikasi matematik antara kelompok eksperimen dan kelompok kontrol digunakan uji t pada a =0,05 setelah prasyarat pengujian terpenuhi.

Test the significance or significance of the regression coefficient obtained sig. 0.000 < 0.05 and tcount = 17.665. There is a significant effect of interest in learning bahasa Indonesia on the ability to write procedural texts

IMPROVING MATHEMATICAL UNDERSTANDING AND COMMUNICATION SKILLS AND STUDENTS’ LEARNING SELF-RELIANCE IN JUNIOR HIGH SCHOOL USING CONTEXTUAL APPROACH

This research is purposed to see the effect of a Contextual Approach in improving not only students’ understanding and communication ability but also their self-reliance in learning mathematics. The method used in this research is quasi-experiment with non-equivalent control group design. This research has been carried out at one junior high school in Cianjur with all of its ninth classes as the population. Out of these classes, two classes are taken as the samples, namely the experimental class and the control class. The Instrument used in this research is a set of tests to evaluate the students’ mathematical communication and understanding skills which have been tested beforehand. The data are obtained through the exposure of these mathematical understanding and communication skills tests. In processing the data, t-test, two-lane ANOVA, and regression have been administered. The result of the research shows that the students' mathematical understanding and communication in experiment class have improved and are better than the control class. The result has also shown that there is not any relationship between mathematical understanding skill and learning self-reliance. However, the result shows that there is a correlation between mathematical communication skill and learning self-reliance

Industrial Cyber Blockchain Physical System for Microgrid in Data Based Predictive Analysis for Automatic Control Analysis

As an efficient distributed renewable energy utilization model, a microgrid is predictable to realize the higher incorporation of the industrial cyber-physical system (CPS) that has gained significant interest in the academia and industry fields. Electric grid is now facing exceptional variations in generation and load as rising number of distributed energy resources (DERs), typically interfaced via power electronics converter, have been positioned, which possess multifaceted technical problems. In the context of electric grid, Blockchain (BC) was primarily developed for peer-to-peer energy trading through cryptocurrency. This paper presents a deep learning based predictive model for automated control analysis (DLBPM-ACS) in BC assisted industrial CPS environment. The presented DLBPM-ACS technique aims to forecast the short-term energy requirement for reducing the delivery cost of electrical energy for consumers. In addition, the presented DLBPM-ACS technique employs BC for effective energy utilization monitoring and trading control. Moreover, the presented DLBPM-ACS technique employs deep belief network (DBN) model for energy prediction process. Furthermore, the artificial ecosystem optimizer (AEO) algorithm is applied for optimal tuning of the hyperparameters related to the DBN approach. A wide range of simulations was conducted and the outcomes demonstrate the better outcomes of the DLBPM-ACS technique

APPLICATION OF A REALISTIC APPROACH TO IMPROVE THE ABILITY OF MATHEMATICAL PROBLEM SOLVING AND SELF REGULATED LEARNING OF JUNIOR HIGH SCHOOL STUDENTS

This study is a quasi-experimental research, which aims to examine the achievement and improvement of problem-solving skills of mathematics and the independence of junior high school students learning through a realistic approach. The population in this study is all students of class VIII SMPN 4 Subang. Samples were taken by random class, obtained two classes of class VIII H as the experimental class and VIII.F as control class. The instrument in this study is a set of mathematical problem-solving test and a set of learning independence scales. The study found that the achievement and improvement of students' mathematical problem-solving ability and the independence of student learning whose learning using realistic learning are better than that of learning using ordinary learning in terms of the initial ability level of students. There is an interaction of mathematical problem-solving abilities between students whose learning uses a realistic approach with a student's initial ability level. Meanwhile, there is no interaction between realistic learning with the level of initial ability of students in generating student self-reliance. Besides, there is no association between mathematical problem solving ability and student learning independence, both in class that use realistic and classroom learning using ordinary learning. The picture of student's performance during realistic learning is more active, it shows the involvement of students both individually and in collaboration with the group, so that it can improve the problem solving ability of mathematics as well as student's learning independence. The description of the students' difficulties in solving the problem of mathematical problem solving ability lies in the indicator about number 5 which is about making the mathematical model because of the lowest percentage indicator
