Publisher : Universitas Dr. Soetomo

Some students have not shown the ability to regulate themselves (self regulated learning) about how to learn. This is part of the impact of conventional learning. Blended learning is a learning model that is widely developed in college. This model provides opportunities for students to learn actively by self-regulation, self-control, self-motivation, and develop self-confidence, and choose or manage their own learning environment to support the effectiveness of learning. This study is based on literature review. Based on some empirical studies, it is concluded that the application of this model can improve self regulated learning learners. Keywords: blended learning, self regulated learning, conventional learning

Let????(????,????)is a connected graph.For an ordered set ????={????1,????2,…,????????} of vertices, ????⊆????(????), and a vertex ????∈????(????), the representation of ???? with respect to ???? is the ordered k-tuple ????(????|????)={????(????,????1),????(????,????2),…,????(????,????????)|∀????∈????(????)}. The set W is called a resolving set of G if every vertex of G has a distinct representation. A resolving set containing a minimum number of vertices is called a basis for ????. The metric dimension of ????, denoted by ????????????(????), is the number of vertices in a basis of ????. Then, for a subset S of V(G), the distance between u and S is ????(????,????)=????????????{????(????,????)|∀????∈????,∀????∈????(????)}. Let Π=(????1,????2,…,????????)be an ordered l-partition of V(G), for∀????????⊂????(????) dan????∈????(????), the representation of v with respect to Π is the l-vector ????(????|Π)=(????(????,????1),????(????,????2),…,????(????,????????)). The set Π is called a resolving partition for G if the ????−vector ????(????|Π),∀????∈????(????)are distinct. The minimum l for which there is a resolving l-partition of V(G) is the partition dimension of G, denoted by ????????(????). In this paper, we determine the metric dimension and the partition dimension of corona product graphs ????????⨀????????−1, and we get some result that the metric dimension and partition dimension of ????????⨀????????−1respectively is????(????−2) and 2????−1, for????≥3.Keyword: Metric dimention, partition dimenstion,corona product graphs

Orientation mathematics are mathematical reasoning abilities. Reasoning is a process or activity is thought to draw the right conclusions based on some of the statements that have been proven or assumed to be true. Students require reasoning ability in solving mathematical problems that involve critical thinking, systematic, logical, and creative. Through the mathematical reasoning students can apply for the alleged then compile evidence, manipulation, and draw conclusions correctly and precisely of the problem or a math problem. Mathematical reasoning skills students are low is one of the fundamental problems in mathematics today. The low student learning outcomes are influenced by many factors, one of which is the use of teaching methods that are less effective and efficient cause unbalance cognitive abilities, affective, and psychomotor student. Learning methods commonly used by mathematics teachers are conventional teaching methods that rely on lectures and main tools blackboard so that students tend to be passive and less involved in the classroom. Conventional teaching methods do not provide the opportunity for students to think and can hamper students' mathematical reasoning abilities. One of the techniques taught are considered accommodative can attract students and increase the activity of thinking students are learning techniques probing prompting. Which is a technique of learning by the teacher presents a series of questions that are guiding and dug so that a process of thinking that links students' knowledge and experience with new knowledge that is being studied.

Tingkat Kemampuan Berpikir Kreatif Siswa dengan Kecerdasan Logis Matematis Sedang dalam Pemecahan Masalah Geometri Asriningsih, Tafsillatul Mufida; Rahmawati, Ana; Lailah, Devi

This is a qualitative-descriptive research. The aims of this study is to describe the level of students creative thinking in geometry problem solving tasks. The subject in this research is a student in the average-level of logical-mathematical intelligence. The subject is on the 7th grade of MTs Al-Hikmah Janti Jombang. The research instrument is logical-mathematical intelligence test, creative thinking test, and interview sheet. The result of this study for fluency critera is student can make two shapes in different size. The result for flexibility criteria is student only use one way to determine the area of a shape, it is by using a formula for counting the area. The result for novelty criteria is student can not make some shapes which are different. All that result shows that student only fulfill one of creative thinking criteria, that is fluency critera. But student can not fulfill the other two criterias of of creative thinking they are flexibility and novelty. Therefore student’s level of creative thinking is on level 1 (almost not creative).

The purpose of this study was to describe the difficulties of students of Physical Education, Faculty of Teacher Treaning and Education, The University of Nusa Cendana, in understanding the material volume of rotary an area. This type of research is descriptive qualitative. The subject of the study was taken from students of the Physics Education second semester, Faculty of Teacher Treaning and Education, The University of Nusa Cendana, as many as 42 people. Data was obtained through tests and documentation of student work results. The results revealed that there were 3 types of difficulties experienced by physics education students of the University of Nusa Cendana, namely (1) difficulty understanding the concept, such as the difficulty in applying the method used correctly, difficult to determine the upper limit and lower limit of certain integrals that were appropriate to the problem and difficult to determine the right function to be countered. (2) difficulty in calculating accuracy, such as not being careful in calculating multiplying positive numbers with negative numbers and squaring a function. (3) difficulty in image representation. Keywords: Volume of rotating an area, difficulty

Salt as one of Indonesia's commodities is very dependent on the length of the dry season. The longer the dry season, the greater the process of evaporation of sea water pumped into the salting area. Rainfall is an indicator that is closely related to the dry season pattern in Indonesia. For this reason, it is necessary to have an early warning system to avoid crop failure in salt farmers. The research variables are rainfall, wind speed, and air temperature in Sumenep, Indonesia. Rainfall variables are determined as output variables (variables to be predicted), while wind speed and air temperature are input variables. In this study, the PCC-based ARIMA-ANFIS hybrid method was used to predict long-term monthly rainfall and examine the consistency of the resulting forecast so that it can be used to compile a yearly salt production calendar. The accuracy of the model in the prediction is measured based on the RMSE criteria. The result of this research is ARIMA model give the best accuracy than the recommended method.
