<![CDATA[Penurunan produksi palawija dan serangan hama daun merupakan masalah utama yang dihadapi oleh kelompok tani Sada Nioga dan Juma Ndeher di Desa Sikeben Kabupaten Deli Serdang. Mengatasi permasalahan tersebut, telah dilakukan kegiatan pengabdian kepada masyarakat berbasis penelitian terapan untuk: (1) mengatasi kekurangan ketersediaan kompos dan pestisida alami; (2) meningkatkan hasil produksi palawija melalui pemanfaatan kompos dan pestisida alami dari limbah pertanian dan peternakan; dan (3) membuka peluang usaha dalam produksi kompos dan pestisida alami. Metode pelaksanaan kegiatan mencakup: penyuluhan penggunaan kompos dan pestisida alami; perancangan perajang mekanik dan fermentor; dan pelatihan produksi kompos dan pestisida alami dari limbah kulit jengkol, cabe busuk dan urine sapi pada tanaman palawija yang dikelola oleh kedua mitra. Hasil kegiatan menunjukkan masing-masing 90% dan 80% anggota kelompok dari Kelompok Tani Sada Nioga dan Kelompok Tani Juma Ndeher telah terampil dalam mengolah kompos dengan durasi pengolahan selama 11 hari. Kualitas kompos (C/N, P2O5, K2O dan N) pada kelompok Sada Nioga adalah masingmasing 8.80%, 2.85%, 1.58% dan 0.08%; sedangkan pada Kelompok Juma Ndeher pada kadar 9.0%, 3.10%, 1.52% dan 0.05%. Produk pestisida yang dihasilkan mengandung metabolit sekunder fenolik(+++), alkaloid (++++) dan saponim (+). Peningkatan produksi tanaman palawija mencapai 27.14% setelah menggunakan kompos dan pestisida alami.]]>

From the data analysis: (1) Student learning outcomes (84.06 ± 7.771) taught by applying PBL model using macromedia flash and student learning outcomes (74.53 ± 6.395) taught by applying DL model using macromedia flash which obtained a t-test of 5.357 and a sig value of 0,000 <0.05 (2) the correlation between student learning outcomes and student motivation in experimental class I obtained a correlation price of 0.955 while sig. (2-tailed) is 0,000 this value is smaller than the critical limit α = 0.05 (0,000 <0.05), meaning there is a very significant relationship between the two variables in the experimental class-I. And the correlation between learning outcomes and student motivation in experimental class II obtained a correlation value of 0.930 while sig. (2-tailed) is 0,000 this value is smaller than the critical limit α = 0.05 (0.0 00 <0.05), means that there is a very significant relationship between the two variables in the experimental class-II.]]>

<![CDATA[Salah satu materi pokok dalam mata kuliah Kimia Umum-II yang memiliki kajian yang cukup luas, sarat dengan konsep dan bersifat abstrak adalah kelarutan/hasil kali kelarutan. Materi pokok tersebut akan lebih tepat diajarkan dengan PBL menggunakan animasi maupun peta konsep sehingga mahasiswa mudah memahmi dan menjadikan perkuliahan lebih bermakna. Selain itu, faktor lain yang juga berpengaruh terhadap pencapaian hasil belajar mahasiswa adalah kemampuan berpikir kritis (KBK) mahasiswa. Hasil penelitian disimpulkan bahwa: 1) terdapat pengaruh yang signifikan penerapan PBL menggunakan animasi terhadap hasil belajar kimia mahasiswa yaitu rata-rata hasil belajar kimia mahasiswa yang diajarkan dengan PBL menggunakan animasi lebih tinggi dibandingkan hasil belajar mahasiswa yang diajarkan dengan model PBL menggunakan peta konsep; 2) terdapat pengaruh yang signifikan KBK mahasiswa terhadap hasil belajar kimia mahasiswa yaitu rata-rata hasil belajar kimia mahasiswa yang memiliki KBK tinggi lebih baik atau lebih tinggi dibandingkan hasil belajar kimia mahasiswa yang memiliki KBK rendah; 3) tidak terdapat pengaruh yang signifikan interaksi antara penerapan PBL menggunakan animasi maupun peta konsep ditinjau dari KBK mahasiswa terhadap hasil belajar kimia yang dicapai mahasiswa.]]>

<![CDATA[Abstract. Chemistry is very appropriate if taught using chemistry concepts with attractive appearance so it is easy to understand. So that students can be attracted and interested in learning the concepts of chemistry and can improve student learning outcomes are achieved, one way to do lecturer is by applying the concept of learning to use the concept map media. In this study a comparison between groups of students who were learning with media concept map with a group of students who were learning without media concept map. Results of the study proved that learning with concept maps media effectively used in improving student learning outcomes and interest study program mathematics FMIPA UNIMED in following the general chemistry course-I on learning stoichiometry. The average increase in learning outcomes (gain scores) students are given learning with concept maps media (lesson-1 = 0.67±0.20; lesson-2 = 0.68±0.16; lesson-3 = 0.79±0.15; and the overall lesson = 0.71 ± 0.11) higher than the average increase in learning outcomes (gain scores) students are given learning without media concept map (lesson-1 = 0.50±0.20; lesson-2 = 0.58±0.16; lesson-3 = 0.62±0.14; and the overall lesson = 0.57±0.11). Similarly, with an average increase in interest in learning (gain score interests) students are given learning with media concept map (0.46±0.10) was higher than the average increase in interest in learning (gain scores interest) given student learning without media concept maps (0.23±0.11). Keywords: concept map, interest, learning outcomes]]>
