This type of research is a research experiment with research design One-Group Pretest-Posttest Design. The population of this study was XI SMKIT DBS 01 Batam Academic Year 2018/2019. The sampling technique is done by saturating sampling techniques with many students 19 students. The type of test given is a descriptive test consisting of 8 pretest questions and 8 posttest questions which then analyze the instrument using construct validity and reliability so that 8 valid and reliable questions are obtained with reliable values of pretest "0.684" and posttest "0.724" to be a matter of pretest and posttest. Normality test using Kolmogorov Smirnov with the results of normal pretest and posttest data. Hypothesis testing is done using the t test two correlated samples obtained sig. (0.00) ≤ . The results of this study indicate that the cooperative learning model of the snowball throwing type is effective against students' mathematics learning outcomes

Penelitian dilatar belakangi oleh kurangnya pemahaman konsep siswa terhadap pelajaran matematika dan minat belajar matematika siswa masih terbilang rendah. Minat belajar berpengaruh untuk meningkatkan kemampuan pemahaman konsep siswa. Tujuan Penelitian ini untuk mendeskripsikan kemampuan pemahaman konsep berdasarkan minat belajar matematika siswa kelas XI SMK Management Training Systems, dengan pendekatan penelitian deskriptif kualitatif. Data yang terkumpul dianalisis menggunakan prosedur menurut Miles dan Huberman yang meliputi reduksi data, penyajian data dan menarik kesimpulan. Adapun indikator pemahaman konsep yang diukur meliputi menyatakan ulang sebuah konsep ( 14I1" ), mengembangkan syarat perlu atau syarat cukup suatu konsep 14I2" , menggunakan prosedur atau operasi tertentu 14I3" , dan mengaplikasikan konsep untuk pemecahan masalah 14I4" .

The objective of the present study was to analyze the metal content of copper and lead in Enhalus accoroides seagrass in Batam Island waters. Samples of seagrass (E. accoroides) were collected from six locations along the western region of Batam Island then dried and performed with acid destruction. The measurements of Cu and Pb in the samples were conducted by Atomic Absorption Spectrophotometer. The result showed that there was an increasing of copper and lead contaminant level on sample E accoroides during two periods in a year. The Cu level ranged from 0.63 to 46.1 mg/kg, meanwhile, lead level ranged from 2.14 to 10.52mg/kg respectively. The highest accumulation of copper and lead were recorded on leaves, it was reached 10.81 mg/kg and 5.98mg/kg, respectively.Penelitian ini bertujuan menganalisis kandungan logam tembaga (Cu) dan timbal (Pb) pada lamun Enhalus accoroides di sepanjang perairan barat Pulau Batam. Sampel lamun dikumpulkan dari enam lokasi kemudian dikeringkan dan dilakukan destruksi dengan asam. Penentuan kadar logam tembaga dan timbal dalam sampel dilakukan dengan spektrometri serapan atom. Hasil penelitian menunjukan adanya peningkatan kadar logam Cu dan Pb pada sampel lamun E. accoroides selama 2 periode sampling dalam 1 tahun. Kadar logam Cu dan Pb pada lamun secara berturut berada pada rentang 0.63-46.1 mg/kg dan 2.14-10.52mg/kg. Akumulasi logam Cu dan Pb dalam lamun E. accoroides tertinggi pada bagian daun sebanyak 10.81 mg/kg Cu dan 5.98 mg/kg Pb.
