Abstract

Munculnya berbagai kekerasan seksual yang terjadi di masyarakat yang disebabkan oleh orang terdekat, terutama dari lingkungan keluarga, memunculkan masalah pentingnya memahami masyarakat terhadap konsep mahram, sebuah konsep dalam ajaran Islam yang mengatur batasan seseorang untuk menikah atau menikahi seseorang berdasarkan nasab, saudara kandung, dan mushoharoh. Dengan memahami konsep itu, seorang Muslim akan tahu bagaimana harus bersikap dengan mahramnya dan bukan mahramnya. Oleh karena itu, penelitian ini bertujuan untuk menguji penggunaan grafik pohon dalam topik teori grafis untuk mempelajari konsep mahram yang terkandung dalam surah An Nisa ayat 23. Penelitian ini termasuk penelitian kualitatif analitik dengan menggunakan instrumen tes, kuesioner dan wawancara. Hasil penelitian ini menunjukkan bahwa penggunaan konsep grafik pohon dapat membantu seorang Muslim untuk belajar dan memahami konsep mahram dengan mudah.

Abstract

In Indonesia, several training pieces have been conducted to develop HOTS-based science questions for elementary school teachers. However, few studies examine how elementary school teachers developed HOTS-based science questions. Hence, the current study is a case study that aims to analyze HOTS-based science questions developed by elementary school teachers in Indonesia. This study employed a descriptive-analytical method by analyzing 60 HOTS-based science questions developed by elementary school teachers. This study involved two raters from one of Indonesia's universities, who are experts in assessing learning for elementary school level to assess the questions. The aspects that are assessed are aspects of conformity with HOTS questions criteria, conformity with the criteria of thinking ability of elementary school students, and conformity with the quality of good questions. This study's findings show that many problems do not meet the first aspect, especially at non-algorithmic points, multiple ways, and multiple interpretations. Next, in the second aspect, most of the question does not use illustration to strengthen the developed question's information. The third aspect is a relatively fulfilled aspect by most developed questions. However, only a few developed questions are judged not to meet this aspect. Hopefully, this study's findings can be an evaluation material for policymakers in education to increase the training quality of HOTS-based science questions for elementary school level in Indonesia.

Abstract

ABSTRAKPenilaian autentik memberikan gambaran yang detail bagi guru dalam melihat kemampuan siswa, kususnya dalam pembelajaran matematika. Namun, masih sedikit hasil penelitian yang mengkaji integrasi konsep literasi matematika terhadap penilaian autentik kususnya dalam pembelajaran matematika secara daring selama Covid-19. Penelitian ini bertujuan untuk menganalisis perencanaan, pelaksanaan, dan hambatan pembelajaran matematika dengan blended learning menggunakan penilaian autentik berbasis literasi matematika pada siswa SMP. Jenis penelitian ini merupakan penelitian kualitatif. Penelitian ini dilakukan terhadap 6 siswa dengan kategori kemampuan matematika awal tinggi, sedang, dan rendah kelas VIII SMP Muhammadiyah 1 Kartasura. Teknik pengumpulan data yang digunakan pada penelitian ini yaitu tes, dokumentasi, dan wawancara dengan keabsahan datanya menggunakan triangulasi sumber dan teknik. Teknik analisis data yang digunakan yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian ini menunjukkan bahwa perencanaan yang harus dilakukan sebelum pelaksanaan yaitu mempersiapkan perangkat pembelajaran, bentuk penilaian autentik, dan instrumen penilaian. Pelaksanaan penilaian dilakukan dalam dua kali pembelajaran yaitu daring dan luring berbasis literasi matematika dengan fokus materi statistika. Selama proses pembelajaran dilakukan pengumpulan nilai dari aktivitas dan hasil pekerjaan siswa. Kemampuan literasi matematika siswa dalam mengerjakan soal statistika serupa PISA pada level dibawah lima sudah bisa sedangkan untuk level lima siswa masih kurang. Hambatan yang dihadapi selama pembelajaran yaitu keterbatasan waktu, proporsi jumlah guru dan siswa yang tidak sepadan, komunikasi yang sulit, kurangnya kesadaran dan tanggung jawab siswa, dan berkurangnya berpikir kritis siswa. ABSTRACTAuthentic assessment provides a detailed picture for teachers in seeing the ability of students, especially in mathematics learning. However, there are still few research results that examine the integration of mathematical literacy concepts to authentic assessments of kususnya in online mathematics learning during Covid-19. This research aims to describe the planning, implementation, and obstacles of mathematical learning by blended learning using authentic assessment based on math literacy in middle school students. This type of research is qualitative research. This research was conducted on 6 students with the category of high, medium, and low initial math skills of Muhammadiyah 1 Kartasura Junior High School. The data collection techniques used in this study are tests, documentation, and interviews with the validity of the data using the triangulation of sources and techniques. Data analysis techniques used are data reduction, data presentation, and conclusion withdrawal. The results of this study show that the planning that must be done before implementation is to prepare learning tools, authentic forms of assessment, and assessment instruments. The assessment is carried out in two learnings, namely online and offline based on mathematical literacy with a focus on statistical material. During the learning process, the collection of values from the activities and results of student work. Students' math literacy skills in doing statistics similar to PISA at levels below five can be done while for level five students are still lacking. Obstacles encountered during learning are time constraints, the proportion of non-commensurate numbers of teachers and students, difficult communication, lack of student awareness and responsibility, and reduced student critical thinking.

Abstract

This paper's focal point is on the nonstandard Optimal Control (OC) problem. In this matter, the value of the final state variable, y(T) is said to be unknown. Moreover, the Lagrangian integrand in the function is in the form of a piecewise constant integrand function of the unknown state value y(T). In addition, the Lagrangian integrand depends on the y(T) value. Thus, this case is considered as the nonstandard OC problem where the problem cannot be resolved by using Pontryagin’s Minimum Principle along with the normal boundary conditions at the final time in the classical setting. Furthermore, the free final state value, y(T) in the nonstandard OC problem yields a necessary boundary condition of final costate value, p(T) which is not equal to zero. Therefore, the new necessary condition of final state value, y(T) should be equal to a certain continuous integral function of y(T)=z since the integrand is a component of y(T). In this study, the 3-stage piecewise constant integrand system will be approximated by utilizing the continuous approximation of the hyperbolic tangent (tanh) procedure. This paper presents the solution by using the computer software of C++ programming and AMPL program language. The Two-Point Boundary Value Problem will be solved by applying the indirect method which will involve the shooting method where it is a combination of the Newton and the minimization algorithm (Golden Section Search and Brent methods). Finally, the results will be compared with the direct methods (Euler, Runge-Kutta, Trapezoidal and Hermite-Simpson approximations) as a validation process.
