There are three objectives that shape the study, first, the study is aimed at identifying different problem-solving skills of the students' who were acquainted with quiz team, lecture and MURDER method. Secondly, the study is to point out the difference of students' problem-solving skills when they are exposed to the three methods in a high, moderate, and low intensity. The third objective is to determine interactions among learning methods, learning activities and problem-solving skills. Quasi experiment is used as a method of the study by applying two experiment classes, and one controlled factorial designed class. In analyzing the data, a two-way Anova analysis and variants analysis are implemented to measure the interaction level among the three variables. The results of the study indicate that (1) there are differences in students' problem-solving skills who were exposed to quiz team, lecture and MURDER method; (2) there are also differences in students' problem-solving skills when they were exposed by the mentioned methods in a high, moderate, and low intensity; there are no relevant interactions among learning methods, learning activities and problem-solving skills. The current results are presented such that they can be used as an aid to the methods of social science learning.

Hama penggerek buah kakao/PBK (Conopomorpha cramerella Snell.) merupakan salah satu hama yang pada tingkat serangan berat dapat mengakibatkan kehilangan hasil kakao mencapai 90%. Penelitian ini bertujuan untuk menguji teknologi pengendalian hama PBK yang ramah lingkungan yaitu penggunaan perangkap feromon seks pada aspek posisi ketinggian perangkap yang efektif. Penelitian dilaksanakan di desa Banda Lama, Kecamatan Amahai, Kabupaten Maluku Tengah yang berlangsung dari bulan Januari sampai Maret 2019. Penelitian ini menguji ketinggian perangkap feromon pada tiga posisi ketinggian perangkap feromon yang berbeda yaitu ketinggian 1 m, 2 m dan 3 m. Data yang diambil adalah jumlah tangkapan imago C. cramerella tiap perlakuan. Hasil penelitian menunjukkan bahwa perangkap feromon dengan ketinggian 1 m yang paling efektif memerangkap hama PBK dengan jumlah tangkapan 85 ekor dan rerata populasi imago terperangkap adalah 10,63 ekor/bulan.
