Abstract: This research is a classroom action research that aims to improve the learning process and to increase mathematics achievement with applied learning model of Problem Based Learning. The subjects of this research was student of class VIII MTs Negeri 1 Indragiri Hilir in academic years 2018/2019, which are 28 students, consist of 13 boys and 15 girls. This research consisit of two cycles, each cycles has four stages, which are planning, implementation, observation, and reflection. The instruments in this research is learning devices and instruments of data collection. Data collected are teacher’s activities and students’ activities and students’ mathematics achievement. Data collection techniques in this research consist of observation techniques and mathematics achievement test techniques. The data of observation results were analyzed in descriptive narrative techniques, while the students mathematic tests were analyzed in descriptive statistical techniques. The result of data analysis show teacher’s and student’s activity have been done very well in cycle II and weakness/deficiency that happened less from cycle I to cycle II. Implementation of PBL model enables students to observe and understand problems and can collect information related to problems given by teachers. The Students mathematics learning outcomes also increased in quiz I and quiz II seen from the achievement of students' knowledge and skills and frequency distribution analysis. The results of this analysis indicate that the application of the PBL model can improve the learning process and improve students mathematics learning outcomes of students of grade VIII students of MTs Negeri 1 Indragiri Hilir in 2018/2019 academic year at Polyhedron form Material.Key Words: Mathematics Achievement, Problem Based Learning, Class Action Research

Abstract

Selain manfaat yang dapat diperoleh, penambangan konvensional seringkali memberi dampak negatif terhadap lingkungan, salah satunya adalah kubangan bekas penambangan yang ditinggalkan dan kemudian menjadi tempat hidup berbagai jenis ikan.Keberadaan parasit pada ikan dapat dijadikan sebagai salah satu indikator tingkat pencemaran yang terjadi di dalam Perairan. Olehnya, penelitian ini bertujuan untuk mengetahui jenis parasit yang menginfeksi ikan nila yang hidup di kolam bekas galian penambangan emas rakyat di Desa Watu-watu Kecamatan Lantari Jaya Kabupaten Bombana.Sampel yang digunakan yaitu ikan nila (Oreochromis niloticus) dengan total jumlah sampel yaitu 30 ekor. Pemeriksaan ektoparasit dilakukan pada organ insang, sisik dan ekor sedangkan pemeriksaan endoparasit dilakukan pada organ lambung, usus dan hati. Hasil penelitian diperolehtiga jenis parasit yang menyerang bagian luar ikan (ektoparasit) yaitu Dactylogyrus sp., Ergasilus sp.,dan Microsporidia (Glugea sp.). Nilai intensitas dari ketiga jenis parasit berkisar antara 0-3,5 ind/ekor sedangkan prevalensi ketiga parasit tersebut berkisar antara 0-90%, sehingga disimpulkan bahwa keberadaan parasit pada ikan tersebut masih tergolong infeksi ringan.Kata kunci : Tilapia O. niloticus, inventarisasi parasit, kolam galian tambang.
