The observations result of the students of SMA Negeri 16 Banda Aceh, showing that the student were less motivated in learning process, they prefer to play and engrossed by their own activities, there were only several students whose really enthusiastic about the material being studied. In order of learning in the classroom went well, so that needs to be innovated the learning activities by using. One of the innovations was used, namely the instructional media, while the learning media that used was the dominoes card and the crossword puzzles. This study aimed to see the effectiveness of learning media on student learning outcomes in learning chemistry by using Dominoes card and crossword puzzle media. This research was the experimental, the research of this research was the student of XI-1 class student experiment class I (dominoes card media) and class XI-2 as experiment class II (crossword puzzle), with total sample was about 37 students. The sample selection based on Purpossive Sampling technique. The instruments used in the form of written tests consist of 20 multiple choice questions with cognitive competence level C1 (knowledge), C2 (understanding), and C3 (application), group worksheet (LKK) in the form of card media and a crossword puzzle, and implementation plan learning (RPP). The data collection techniques were by pretest and posttest, and then analyzed were by using the normality test, homogeneity test, and T test on hypothesis test with 19-version version of the Statistical Program for Social Science (SPSS) program. The results showed that there was no significant difference to the learning outcomes of students who were taught using domino card media and TTS media. It can be concluded that the domino card media and TTS media are very effective in improving the learning outcomes of the students of SMA Negeri 16 Banda Aceh.

Kepatuhan mengkonsumsi tablet zat besi diukur dari ketepatan jumlah tablet zat besi yang dikonsumsi, ketepatan cara mengkonsumsi tablet zat besi, frekuensi konsumsi tablet zat besi perhari. Tujuan penelitian ini untuk mengetahui faktor pengetahuan, sikap, dukungan keluarga dan dukungan tenaga kesehatan terhadap kepatuhan mengkonsumsi tablet zat besi (Fe) pada ibu hamil di wilayah kerja Puskesmas Simeulue Timur Tahun 2018. Desain penelitian dilakukan secara survei analitik kuantitatif dengan pendekatan cross sectional. Populasi dalam penelitian adalah semua ibu hamil trimester II dan III yang mendapatkan tablet Fe sebanyak 255 orang dan Sampel yang digunakan sebanyak 72 orang yang mendapatkan tablet Fe dengan menggunakan sampel acak sistematis dan teknik sampel acak sederhana. Analisis yang digunakan adalah analisis univariat, bivariat dengan uji chi-square, analisis multivariat dengan uji regresi berganda binary. Berdasarkan analisis bivariat dengan uji chi-square, Ada pengaruh faktor pengetahuan, sikap, dukungan keluarga dan tenaga kesehatan terhadap kepatuhan mengkonsumsi tablet  Fe pada ibu hamil α = 0.05 diperoleh hasil yaitu nilai p pengetahuan = 0.036 nilai p sikap = 0.003, nilai p dukungan keluarga = 0.013, dan nilai p dukungan tenaga kesehatan = 0.012. Berdasarkan analisis multivariat diketahui variabel sikap paling dominan memengaruhi kepatuhan mengkonsumsi tablet Fe pada ibu hamil dengan nilai p = 0.001 dan  Exp (B) = 10.579.  Oleh karena itu, ibu hamil trimester II dan trimester III perlu untuk meningkatkan pengetahuan tentang pentingnya mengkonsumsi tablet Fe dan diharapkan peran aktif keluarga serta tenaga kesehatan untuk tindakan pencegahan terjadinya anemia pada ibu hamil.

Due to its limiting factor of the cycle-life on Zn-polyaniline (PANI) rechargeable battery, the surface morphology and electrochemical properties have been extensively investigated. However, there are no studies that found on the chemical structure of PANI electrode before and after used in the battery with spectroscopy. Here, the Zn-PANI Battery was tested through a 60-cycle discharging process using 10 mA fixed current. The Open Circuit Voltage (OCV) at this condition was ± 1.3 V. The Raman spectra at 488 nm on PANI discharge showed increasing intensity at 1495 cm -1 υ(C=N). Furthermore, the new peak appeared on the band at 1212 cm -1 υ(N=Q=N) and 1166 cm -1 υ(C-H), related to mode on the benzenoid ring. This investigation indicated the formation of Emerald in Bases (EB), caused by the consumption of protons by Zn metal during the filling process.

Memiliki anak yang sehat, cerdas dengan bergizi yang seimbang adalah dambaan semua orangtua. Anak di bawah umur lima tahun termasuk salah satu kelompok yang berisiko tinggi mengalami gangguan perkembangan fisik apabila ada gangguan gizi. Tujuan penelitian untuk mengetahui efektifitas penyuluhan dan media audio visual terhadap peningkatan pengetahuan dan sikap ibu anak balita gizi kurang di Puskesmas Medan Sunggal. Desain penelitian yang digunakan adalah penelitian eksperimen menggunakan quasi experimental desain dan bentuk nonequivalent control group design. Populasi dan sampel dalam penelitian ini adalah seluruh ibu yang memiliki anak balita (usia 0-60 bulan) gizi kurang berjumlah 32 ibu dengan menggunakan teknik sampling jenuh. Analisa data yang digunakan yaitu analisa univariat dan bivariat dengan uji wilcoxon. Berdasarkan hasil uji wilcoxon, pengetahuan pada penyuluhan memiliki nilai = Z -2,965 dan nilai p = 0.003 dan pengetahuan pada media audio visual memiliki nilai Z = -3,213 dan nilai p = 0,001. Sedangkan sikap pada penyuluhan memiliki nilai = Z -2,754 dan nilai p = 0.006 dan  sikap pada  media audio visual memiliki nilai Z = -3,068 dan nilai p = 0,002. Diperoleh kesimpulan bahwa media audio visual lebih efektif daripada penyuluhan dalam peningkatan pengetahuan dan sikap tentang gizi seimbang untuk anak balita.

This study aims to improve student learning outcomes , and knowing the students' response to the application of Advance Organizer on Atomic Structure material . Subjects in this study were students of class X SMA Negeri 11 IA3 Banda Aceh , totaling 26 people . This type of research is descriptive qualitative . To find out improving student learning outcomes used about posttest , and the questionnaire used to determine students' response to the learning model Advance Organizer . From the results obtained posttest student learning outcomes at 83.65 ; as well as the students' responses by 96.15 % who expressed delight in learning model Advance Organizer . Based on the results of this study concluded that an increase in student learning outcomes and positive student responses show the learning progress of students with learning model Advance Organizerpada use of the atomic structure of matter.
