Analisis Kesulitan Siswa Kelas II Sekolah Dasar dalam Menyelesaikan Soal Pemecahan Masalah Matematika Materi Perkalian dan Pembagian

One of the competencies that students must master in learning mathematics is to perform addition, subtraction, multiplication, division and mixed operations, including those involving fractions. So, students can solve problems which include the ability to understand problems, design mathematical models, solve models, and interpret the solutions obtained. The purpose of this study was to determine the types of errors made by students, to describe the students' abilities, and to determine the factors that caused students of Class IIA SDN Pandeanlamper 05 Semarang to experience difficulties in solving math problem solving problems. The research method used is descriptive qualitative research methods. The subjects of this study were 25 students of Class IIA SDN Pandeanlamper 05 Semarang. After being analyzed, the results obtained were that students had difficulty solving problems solving math problems with the material of multiplication and division, namely 1) Students did not understand the meaning or content of story problems, 2) The students' ability to memorize multiplication and division was still low, 3) External factors such as health conditions, socioeconomic status, and student attendance have an effect on students' ability to solve math problem solving problems. This proves that the difficulties experienced by students in solving math problem solving problems are caused by two factors, namely internal factors and external factors.One of the competencies that students must master in learning mathematics is to perform addition, subtraction, multiplication, division and mixed operations, including those involving fractions.

URBAN MINING BATERAI LITHIUM BEKAS SEBAGAI SUMBER ALTERNATIF BAHAN BAKU BATERAI LITHIUM

An urban mining proposal has been made that offers a lithium battery waste managementsolution. This is motivated by the absence of a waste management system that specificallyhandles lithium batteries. The research was conducted quantitatively for electrochemicaldischarge experiments and qualitatively for data collection, processing and formulation of urbanmining proposals. From the experimental results, it was found that 5% NaCl is the optimumconcentration for electrochemical discharge. Obstacles are still found based on qualitativeanalysis of waste management data in Indonesia, especially for lithium battery waste. The scopeof the proposed urban mining system includes the people as the user and the temporarycollectors. Hopefully this urban mining design is beneficial for an effective and environmentallyfriendly lithium battery waste management plan.Telah dibuat usulan urban mining yang menawarkan solusi tata kelola sampah baterai lithium.Hal ini dilatarbelakangi belum adanya sistem pengelolaan sampah yang spesifik menanganibaterai lithium. Penelitian dilakukan secara kuantitatif untuk percobaan electrochemical discharge dan kualitatif untuk pengumpulan data, pengolahan dan perumusan usulan urban mining. Dari hasil penelitian eksperimental didapatkan bahwa NaCl 5% merupakan konsentrasi optimum untuk electrochemical discharge. Analisa kualitatif dari data tata kelola sampah di Indonesia didapatbahwa masih ditemukan kendala khususnya untuk sampah baterai lithium. Sistem urbanmining yang diusulkan mencakup lingkup masyarakat dan pengumpul sementara. Diharapkan usulan urban mining ini bisa memberikan masukan untuk perencanaan tata kelola sampah baterai lithiumyang efektif dan berwawasan lingkungan

ANALISIS KESULITAN BELAJAR SISWA KELAS V MATERI PERKALIAN DAN PEMBAGIAN BILANGAN PECAHAN CAMPURAN DI SD NEGERI 07 GUBUG GROBOGAN

Penelitian ini bertujuan untuk mengetahui dan mendeskripsikan kesulitan belajar atau Learning Obstacle siswa kelas V dalam belajar perkalian dan pembagian bilangan pecahan campuran. Selain itu penelitian ini untuk mengetahui apa saja penyebab siswa mengalami kesulitan belajar perkalian dan pembagian bilangan pecahan campuran. Penelitian ini menggunakan pendekatan kualitatif yang menggunakan metode pedoman tes tertulis, wawancara, angket dan dokumentasi. Berdasarkan hasil analisis tes tertulis, wawancara dan angket menunjukkan adanya Learning Obstacle yang terbagi menjadi tiga yaitu Ontogenical Obstacle, Epistemological Obstacle, Didactical Obstacle. Ontogenical Obstacle terjadi karena kesulitan dalam menghitung perkalian dan pembagian. Epistemological Obstacle yang terjadi karena tidak dapat menyederhanakan bilangan pecahan campuran. Didactical Obstacle terjadi karena tidak memberikan keterangan diketahui, ditanya, hasil akhir pada soal cerita. Penyebab siswa mengalami kesulitan Ontogenical Obstacle karena rendahnya IQ siswa sehingga siswa mengalami kesulitan dalam menghitung dan mengingat materi yang sudah dipelajari. Epistemological Obstacle karena siswa tidak mengetahui konsep bilangan pecahan campuran, tidak mengetahui cara menghitung perkalian dan pembagian bilangan pecahan campuran, hal ini bisa terjadi karena siswa tidak pernah mempelajari materi yang sudah diajarkan guru. Didactical Obstacle yang dialami oleh siswa diakibatkan karena guru kurang memberikan soal yang bervariasi sehingga saat siswa menemukan soal cerita siswa mengalami kesulitan dalam memahami dan menyajikan data.Kata Kunci: Learning Obstacle, Bilangan Pecahan Campuran, Sekolah Dasar

The Development Research on Hand-Puppets in “Cita-Citaku” Theme for the Fourth Grader of SDN Gotputuk Blora

There are some media which can be used in the teaching - learning process. One of them is hand-puppets. This media is different from the other hand-puppets because it is made personally for each theme, and here the researchers focused on the theme “Cita-Citaku”. This media is simple, economic, and efficient to be played. These media can also attract and build young learners’ imagination, because it is made from colourful-attractive fabric, like flannel. This study focuses on the implementation of hand-puppets as teaching media in “Cita-Citaku” theme for the fourth grader of SDN Gotputuk Blora, Central Java. This theme of teaching material is so important to be taught to the students so that they can understand well how to reach their dreams in the future. It is an R&D research. The data were collected by interviewing, giving tests, and observing the teachers and students, and taking the documentation. Based on the collected data, the students’ scores of the implementation of hand-puppets in “Cita-Citaku” theme were increased. The students characters on self-confidence, teamwork, hard-work, and curiosity were increased positively too. The suggestion to the teachers is they must be a facilitator, motivator, and innovator to the students. They must motivate their students to ask and give an opinion. For the next researcher(s), we suggest them to make the similar research about hand-puppets in different field and theme
