Penelitian ini bertujuan untuk mengetahui pengaruh penerapan metode pembelajaran demonstrasi terhadap hasil belajar peserta didik kelas V. Metode yang digunakan dalam penelitian ini (experiment quasi). Sampel penelitian yaitu 15 peserta didik kelas VA sebagai kelas kontrol dan 15 peserta didik kelas VB sebagai kelas eksperimen. Teknik pengambilan data pada penelitian ini menggunakan teknik Purposive Sampling. Teknik pengumpulan data dalam penelitian ini menggunakan soal pre-test  dan soal post-test. Teknik analisis data menggunakan hasil Uji t. Hasil analisis data diperoleh bahwa rata-rata hasil belajar peserta didik kelas eksperimen lebih tinggi dari nilai rata-rata hasil belajar peserta didik kelas kontrol.  Hasil perhitungan Uji N-Gain, menunjukkan bahwa nilai rata-rata nilai N-Gain score untuk kelas eksperimen (metode demonstrasi) adalah sebesar 51.1695 atau 51% termasuk dalam kategori kurang efektif. Sementara untuk rata-rata N-Gain score untuk kelas kontrol adalah sebesar 38.4839 atau 38.5% termasuk dalam kategori tidak efektif. Hasil uji indipendent sample t test diketahui nilai Sig. (2-tailed) sebesar 0.280 dan nilai 0.280 > 0,05 maka H0 diterima, jadi dapat disimpulkan bahwa pembelajaran dengan menggunakan metode demonstrasi pada kelas eksperimen tidak terdapat perbedaan yang signifikan dengan kelas kontrol yang menggunakan metode konvensional.

        This study was done due to the lack of motivation of students in SMKN Baso to write. One of the media used to increase students’ motivation is blogging. The design of this research was experimental research. The data was obtained through a questionnaire. The populations of this research were the second-grade students at SMKN 1Baso academic years 2019/2020 consisting of 174 students. To determine the sample, the researcher used purposive sampling by choosing two classes, they were XI Perkantoran 1 and XI Perkantoran 2. XI Perkantoran 1 was treated as a control class that applies with conventional media in writing while XI Perkantoran 2 was treated as an experimental class that applies blog in writing. To analyze the data collected, the researcher used the t-test formula to test the hypothesis and consult the result into t-table with level significance α = 0,05. Based on the result of the research, the mean score of the questionnaire after giving the treatment of the experimental class was 72,28 was higher than the mean score of the control class was 65,85. Then it was analyzed by using t-test and the result of t-obtained was 4,47 with the degree of freedom 39 and the level significance α = 0,05. Through comparing the t-obtained (4,47) to t-table (2,042) on the same degree of freedom and level significance, it was found that the value of t-obtained was higher than the value of t-table. Thus the hypothesis (Ha) is accepted which stated using a blog gives a better effect on students’ motivation to write analytical exposition text.

Studi memperkirakan emesis gravidarum terjadi pada 50-90% kehamilan. Mual muntah pada kehamilan memberikan dampak yang signifikan bagi tubuh dimana ibu menjadi lemah, pucat dan cairan tubuh berkurang sehingga darah menjadi kental (hemokonsentrasi). Keadaan ini dapat memperlambat peredaran darah dan berakibat pada kurangnya suplay oksigen serta makanan ke jaringan sehingga dapat membahayakan kesehatan ibu dan janin. Salah satu terapi yang aman dan dapat dilakukan untuk mengurangi keluahan mual muntah pada ibu hamil adalah pemberian aromaterapi lemon. Penelitian bertujuan untuk mengetahui efektifitas aroma terapi lemon untuk menangani emesis gravidarum. Penelitian ini menggunakan rancangan Quasi experiment  dengan  one group pre-post test design. Populasi penelitian adalah ibu hamil yang mengalami emesis gravidarum di Kecamatan Berbah, Sleman. Jumlah sampel 20 ibu hamil trimester pertama yang diambil dengan teknik purposive sampling. Pengukuran mual muntah dilakukan debelum dan setelah  pemberian aromaterapi lemon menggunakan Indeks Rhodes. Analisa data menggunakan uji Paired t-test. Hasil penelitian didapatkan rata-rata skor mual muntah sebelum pemberian aromaterapi lemon berdasarkan Indeks Rhodes pada Ibu Hamil dengan emesis gravidarum yaitu 22,1 dan terjadi penurunan skor setelah pemberian aromaterapi lemon menjadi 19,8. Ada pengaruh pemberian aromaterapi lemon dengan pengurangan mual muntah pada ibu hamil (p-value = 0.017). Berdasarkan hasil penelitian dapat disimpulkan pemberian aromaterapi lemon efektif untuk mengurangi emesis gravidarum pada ibu hamil trimester pertama.  Kata kunci: aromaterapi lemon, emesis gravidarum THE EFFECTIVENESS OF LEMON AROMATHERAPY FOR HANDLING EMESIS GRAVIDARUM   ABSTRACT Studies estimate that nausea and vomiting (emesis gravidarum) occur in 50 – 90% of pregnancies. Nausea and vomiting of pregnancy have a significant impact on the body in which it makes a mother becomes weak, pale, and decreasing body fluid so that the blood becomes thick (hemoconcentration). This situation can slow down blood circulation and inflict the lack of oxygen and food supplies to the body tissues so that it can endanger the health of the mother and fetus. One of the therapies that is safe and can be conducted to reduce nausea and vomiting of pregnancy is by giving the lemon aromatherapy treatment. The research aims to determine the effectiveness of the aroma of lemon therapy to deal with emesis gravidarum. This study applied quasi-experimental research with one group pretest-posttest design. The population of this study was pregnant women who experienced emesis gravidarum. Furthermore, samples were 20 mothers from Berbah, Sleman taken by using a purposive sampling technique. Nausea and vomiting were assessed between before and after giving lemon aromatherapy using the Rhodes Index. The data were analyzed using the paired t-test. The mean score of nausea and vomiting before giving lemon aromatherapy on mother with emesis gravidarum based on the Rhodes Index was 22.1. However, it decreased after given lemon aromatherapy treatment to 19.8. Therefore, there was an effect on giving lemon aromatherapy treatment toward the decrease of nausea and vomiting for pregnant women (p-value = 0.017). Lemon aromatherapy is effective to reduce emesis gravidarum.  Keywords: lemon aromatherapy, emesis gravidarum
