Abstract

Tujuan penelitian ini adalah: (1) meningkatkan motivasi belajar, (2) meningkatkan prestasi belajar, dan (3) mendeskripsikan tanggapan siswa terhadap penerapan model STAD. Penelitian ini adalah penelitian tindakan kelas yang melibatkan 35 siswa kelas X 3 SMA Negeri 1 Srono pada semester genap tahun pelajaran 2015/2016. Data motivasi dan tanggapan terhadap model pembelajaran kooperatif tipe STAD dikumpulkan dengan kuisioner. Data prestasi belajar siswa dikumpulkan dengan tes. Penelitian berhasil jika, ketuntasan klasikal 85% , KKM 75, motivasi belajar dalam kategori tinggi, dan tanggapan siswa berkategori positif. Hasil penelitian menunjukkan bahwa: 1) penerapan model STAD dapat meningkatkan motivasi belajar (x ̅ siklus I = 74,03 dengan kategori tinggi, x ̅ siklus II = 76,60 dengan kategori tinggi), 2) penerapan model STAD dapat meningkatkan prestasi belajar (x ̅ siklus I = 79,29 dengan ketuntasan klasikal 77,14%, x ̅ siklus II = 82,28 dengan ketuntasan klasikal 91,43%); dan 3) tanggapan siswa terhadap penerapan model STAD berkategori positif (x ̅ = 77,2).Kata Kunci : motivasi belajar, pembelajaran kooperatif tipe STAD, prestasi belajar. This study aimed at (1) improving learning motivation, (2) improving learning achievement, and (3) describing the students' responses toward the implementation of STAD model. This research was a classroom action research which was conducted in two cycles of learning and involved 35 students of grade X 3 of SMAN 1 Srono in even semester of academic year 2015/2016. Data of motivation and the responses toward the STAD model were collected by questionnaire, while data of students’ learning achievement were collected by a multiple-choice test. Research was called to be success if classical completeness was 85% with KKM 75, learning motivation was in the category “high”, and the student responses were categorized positive. The results show that: 1) the implementation of STAD model can increase learning motivation (cycle I = 74,03 with high category, the second cycle = 76,60 with high category), 2) the implementation of STAD model can improve learning achievement (x ̅ of cycle I = 79,29 with 77,14% classical completeness, x ̅ of cycle 2 = 82,28 with 91,43% classical completeness); and 3) the students’ responses toward the implementation of STAD model are in positive category.keyword : learning achievement, learning motivation, STAD type cooperative learning.

Abstract

Society in Desa Namo Bintang using water wells that contains high levels of Cd that exceeded the quality standard due to groundwater contamination from landfill waste, so that it was  required a method to reduce levels of Cd in water wells in the village. This study aimed to know determine levels of Cd in water wells and to utilize the hyacinth powder for reducing levels of Cd  in water wells. The type of this research was Quasi Experiment with the Completely Randomized Design as study design. Object of this research was the water wells with higher levels of Cd was more than 0,005 mg/L, the treatment was by adding10 mg, 20 mg and 30 mg hyacinth powder with three repetitions in an effort to reduce the levels of Cd in water wells. The results showed that the initial levels of Cd in water wells was0,00685 mg/L, the levels of Cd in water wells which did not receive additional of hyacinth powder (as control) did not show any reduction, meanwhile by adding 10 mg, 20 mg and 30 mg hyacinth powder respectively reduce for 28,8%, 33,72%, 26,28%. The test results of Two Way Anova showed there were significant differences in the treatment of various Cd levels decrease (p=0,000< 0,005). The test result of Bonferroni indicated that the addition of 20 mg hyacinth powder was the most effective between the others for reducing the levels of Cd in water wells in the village. Therefore  for the people in the Namo Bintang village expected to utilize the hyacinth powder to reduce levels of Cd so that the water that used become more clean and accordance with standards estabilished. Keywords: Water Wells,  Hyacinth Powder, Cd Levels
