Abstract

Abstract  Stoichiometry is one of the subjects in the general chemistry-I course,which has a fairly extensive study, laden with concepts and abstract. Stoichiometrywould be more appropriately taught using concept maps media so that studentseasily understand and make lectures more meaningful. In addition to the use ofconcept  maps media, other factors also affect the learning outcomes of studentsis learning interest of students. In this research, comparison of the results ofstudying chemistry among the group of students who are taught by the mediamap concept with a group of students who are taught without media concept map interms of student learning interest. The final conclusion is that: (1) there issignificant influence media use of concept maps to the learning outcomes of studentson the subject of chemical stoichiometry  where  the  average  results  of studying chemistry  students  are  taught  using concept maps media is higher than studentlearning outcomes are taught without using the media map concept; (2) there issignificant influence on the students interest in learning outcomes of students onthe subject of chemical stoichiometry where the average results of studyingchemistry students who have a high interest in learning was higher than the resultsof studying chemistry student who has a low learning interest; (3) there is nosignificant effect of interaction between media use of concept maps and the interestof student learning to the learning outcomes achieved chemistry student on thesubject of stoichiometry.

Abstract

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.

Abstract

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

Abstract

Abstract This research aim to know how effect of computer animation instructional media and student motivation for student learning outcomes on teaching redox reaction. The quasy experiment methods conduct and achievement test using as instrument. Data was analysed using inferential statistic method. The results and hypothesis test shows: (1) there is a significant influence the use of computer animation media on learning redox reaction and electrochemical to achievement of students, in which chemistry learning achievement of students taught using computer animation media (84.38) is higher compared chemistry learning achievement of students who are taught without using the computer animation media (78.25), (2) there is a significant influence on learning motivation to achievement of students, in which chemistry learning achievement of students who have a high learning motivation (84.59) higher than chemistry learning achievement of students who have a low learning motivation (78.89), and (3) there is no significant influence of the interaction between the use of computer animation media and learning motivation of students to achievement of student.Kata kunci: Media Animasi, Motivasi, Prestasi Belajar, Kimia.
