Abstract

This research aims to describe the types of errors and the causes of students making mistakes in solving mathematics story problems. The research method used is qualitative descriptive research. The population of this research was students in Makassar with a total of 23 students and 2 students were determined as the research sample. The results of the research found that most students experienced errors due to a lack of understanding of the existing material and behavior that tended to be careless and hasty so they made mistakes in solving math story problems. There were 4 types of student errors, namely (1) errors in reading the questions occurred because the participant's students failed to understand the content or meaning of story problems and were not able to identify relevant information in mathematics story problems (2) Conceptual errors occur because students do not understand and master the concepts of the material being taught so they are confused when determining what method is appropriate for solving story problems mathematics, (3) errors in procedures/steps occur. After all, students are not careful in carrying out calculation operations. This can be seen in the ability test of students who make calculation errors in the stages of solving story problems. (4) Errors in concluding occur because students think that concluding is not important, they assume that if they have got the final score from the calculation then the solution to the story problem has been completed.

Abstract

Salah satu tanaman yang dapat dijadikan sebagai obat adalah tanaman Kulit Buah Pisang Muli (Musa Acuminata Linn). Daun dan kulit batang buah pisang muli dimanfaatkan sebagai obat berbagai macam penyakit, seperti pendarahan usus, amandel, memperbaiki pertumbuhan rambut. Kulit Buah Pisang Muli (Musa Acuminata Linn dapat dijadikan sediaan serum Kulit Buah Pisang Muli (Musa Acuminata Linn sebagai antioksidan, metode penelitian dilakukan secara eksperimental laboratorium, ekstrak Kulit Buah Pisang Muli (Musa Acuminata Linn) dimaserasi menggunakan pelarut etanol 96%. Dibuat sediaan serum dengan tiga konsentrasi 3%, 5%, 7%, kontrol negatif K(-), dan kontrol positif K(+) kemudian dilakukan uji organoleptis, homogenitas, pH, daya sebar, viskositas dan cycling test yang dilakukan selama 6 siklus. Hasil uji Serum Dari Ekstrak Etanol Kulit Buah Pisang Muli (Musa acuminata Linn) dapat dijadikan sediaan serum yang stabil secara fisika dan kimia serta sediaan Serum Dari Ekstrak Etanol Kulit Buah Pisang Muli (Musa Acuminata Linn) memiliki khasiat sebagai antioksidan. Hasil penelitian menunjukkan pada formula I memiliki aktivitas nilai IC50 50,25 µg/mL, formula II memiliki aktivitas nilai IC50 30,96 µg/mL, formula III memiliki aktivitas nilai 7,85 µg/mL, sedangkan control positif memiliki aktivitas nilai IC50 13,35 µg/mL. aktivitas antioksidan dari semua sediaan memiliki sifat antioksidan yang sangat kuat karena <50 ppm kecuali formula II yang memiliki sifat antioksidan kuat karena >50 ppm.

Abstract

Biodiversity has value in the health sector, one of which is in the use of plants as medicine. Medicinal plants are closely related to traditional medicine by local communities. Exploration of local knowledge regarding the use of natural materials as medicines is carried out in order to obtain information about data on traditional herbal medicines used by ethnic groups in Indonesia. The Tolaki tribe is one of the ethnic groups that are widely spread in the province of Southeast Sulawesi, including in the Iwoimendaa sub-district, Kolaka district. This study aims to explore local knowledge related to the types of medicinal plants, parts of plants used as medicine and how to process plants as medicine by the Tolaki tribe in the villages of Iwoimendaa, Ladahai, Lambopini, Lawolia, Tamborasi, Ulukalo and Watumelewe, Iwoimendaa sub-district, Kolaka district. The results of the study showed that the diversity of plant species based on the families used by the Tolaki tribe in the Iwoimendaa sub-district consisted of 68 species and 41 families, where the most widely used were from the Zingiberaceae family. The most widely used parts of the plant are the leaves, followed by the fruit, rhizome, herbs, tubers, roots, exudates/sap, stems and seeds. The most common way of processing plants is boiling. Other processing methods include brewing, grating, pounding, chewing, smearing, dripping, kneading, applying, sticking, squeezing and without mixing.

Abstract

Penelitian ini bertujuan untuk mengetahui keefektifan pembelajaran Problem Solving melalui Missouri Mathematict Project untuk meningkatkan hasil belajar peserta didik. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) dilakukan kelas VII MA. Arrahman Patimpang Kab.Bone. yang berjumlah 26 peserta didik. Lembar observasi dianalisis secara kualitatif sedangkan tes pembelajaran Problem Solving melalui Missouri Mathematict Project dianalisis secara kuantitatif dengan mengunakan analisis statistik deskriptif. Hasil pengolahan data ketuntasan hasil belajar diperoleh rata-rata siklus I menunjukkan nilai frekuensi yang tidak tuntas sebanyak 21 dengan persentase 80,77 %. Untuk nilai frekuensi yang tuntas sebanyak 5 dengan persentase 19,23% dengan jumlah 26 peserta didik. Pada siklus II nilai frekuensi yang tidak tuntas sebanyak 4 dengan persentase 15,39 %. Untuk nilai frekuensi yang tuntas sebanyak 22 dengan persentase 84,61%. Pada siklus I tidak ada peningkatan yang efektif pada hasil belajar. Sedangkan pada siklus II terjadi peningkatan yang efektif hasil belajar pada pembelajaran Problem Solving melalui Missouri Mathematict Project. Kesimpulannya adalah Problem Solving melalui Missouri Mathematict Project efektif meningkatkan hasil belajar matematika. Selanjutnya saran peneliti untuk studi lanjut kemampuan berpikir kritis matematis peserta didik perlu diterapkan dalam pembelajaran agar terstuktur dan sistematis.
