Abstract

This research is aimed to describe the effectiveness of PLGI learning model on electrolyte non-electrolyte solution in improving conclude skill and comunicating skills. The population in this study was all students of class X in Islamic Senior High School 2 Tanjung Karang in 2013-2014 year. Sampling use purposive sampling technique and obtained class X3 and X8 as sample. This is a quasi-experimental research using Non Eqiuvalent (Pretest-Posttest) Control Group Design. Effectiveness of learning with PLGI was measured based on improvements n-Gain significant. The results of this research showed that average value of n-Gain comunicating of skills in experiment class and control class are 0,40 and 0,57 and the average value of n-Gain of conclude skills  in experiment class and control class are 0,70 and 0,79. This research showed that the PLGI learning model of electrolyte non-electrolyte solution material is effective in improving the communicating skills and conclude skills students. Penelitian ini bertujuan untuk mendeskripsikan efektivitas model PLGI dalam meningkatkan keterampilan menyimpulkan dan mengkomunikasikan pada materi larutan elektrolit non-elektrolit. Populasi dalam penelitian ini adalah seluruh siswa kelas X MAN 2 Tanjung Karang Bandar Lampung Tahun Ajaran 2013-2014.  Sampel penelitian diambil menggunakan teknik purposive sampling dan diperoleh kelas X3 dan X8. Penelitian ini menggunakan metode kuasi eksperimen dengan Non Equivalent (Pretest and Posttest) Control Group Design. Efektivitas pembelajaran PLGI diukur berdasarkan perbedaan n-Gain yang signifikan. Hasil penelitian menunjukkan nilai rata-rata n-Gain keterampilan mengkomunikasikan untuk kelas kontrol dan eksperimen masing-masing 0,40 dan 0,57  dan rata-rata  n-Gain keterampilan menyimpulkan untuk kelas kontrol dan eksperimen masingmasing 0,70 dan 0,79. Hal ini menunjukkan bahwa model PLGI efektif pada materi larutan elektrolit non-elektrolit dalam meningkatkan keterampilan menyimpulkan dan mengkomunikasikan. Kata kunci: elektrolit non-elektrolit, keterampilan mengkomunikasikan, keterampilan menyimpulkan, model PLGI.

Abstract

Gynura procumbens (Sambung nyawa) has been widely used as a herbal medicine since it is rich in bioactive compounds. Moreover, Gynura procumbens also has become a potential plant that control parasitic nematode infection. The research aimed to investigate the effect of G. procumbens on sheep performance, health status, and methane production. A total of twelve six-month-old lambs (ABW 11.27 ± 2.19 kg) were categorized based on live weight and fed one of feed treatments: wild grasses (40%) and concentrate (60%) (control/P0), P0 + 5% G. procumbens (P1), and P0 + 10% G. procumbens (P2). Feed intake, parasitic infection, and physiological status were measured weekly. G. procumbens at 5% level showed normal respiration rate, but the respiration and heart rates of lambs were abnormal. The 10% G. procumbens increased daily weight gain. G. procumbens addition up to 10% reduced the number of Strongyloides on feces and enteric methane emissions compare to control. It concluded that 5% G. procumbens can be used as an anthelmintic forage by improving health status, performance, and reducing methane emissions of sheep. Key words: Gynura procumbens, herb medicine, nematodes infection, parasite population, sheep performance
