Abstract:The lack of audio-visual teaching materials to improve students ' understanding Abstrak: Penelitian ini dilatarbelakangi oleh kurangnya bahan ajar audio-visual untuk dapat meningkatkan pemahaman siswa pada materi kalor. Tujuan dari penelitian ini adalah menghasilkan bahan ajar audiovisual yang valid, praktis serta dapat meningkatkan pemahaman siswa mengenai materi kalor. Jenis penelitian ini adalah penelitian dan pengembangan dengan tahapan 4D (Define, Design, Develop, Dessiminate). Tahap Dessiminate tidak dilakukan karena adanya keterbatasan waktu dan biaya. Teknik sampling yang digunakan adalah Cluster Random Sampling. Sampel dari penelitian ini adalah siswa kelas SMP N 1 Pariaman. Terdapat dua instrumen yang digunakan untuk mengumpulkan data dalam penelitian ini yaitu: lembar validasi terkait dengan penilaian ahli dalam bidang fisika terhadap kebahasaan, substansi materi, tampilan bahan ajar, desain pembelajaran serta software dan lembar praktikalitas guru serta siswa terkait dengan penilaian keterpakaian produk dalam kegiatan pembelajaran pada tahap pendahuluan, inti dan penutup. Berdasarkan hasil uji validitas produk kepada dosen ahli fisika didapatkan rata-rata penilaian sebesar 85,9 dengan kategori sangat valid. Produk yang dikembangkan juga praktis digunakan dalam kegiatan pembelajaran menurut guru dengan rata-rata penilaian 85,6 dan praktis menurut siswa dengan rata-rata penilaian 85. Berdasarkan hasil uji statistik untuk tes awal dan tes akhir siswa didapatkan nilai t-hitung lebih besar dari t-tabel, sehingga dapat disimpulkan bahwa penggunaan bahan ajar video dan animasi dapat meningkatkan pemahaman siswa terhadap materi kalor.
This study aims to determine the difference between science study results using experimental methods and methods talks in terms of communication skill. The type of research is quasi experiment. Data collection technique using documentation, questionnaire, and test. Data analysis technique using descriptive analysis and anacova. Descriptively, science study results using experimental method in very high level while methods talks in high level. Communication skill of experimental methods in very high level and methods talks in high level. Comparatively, there's an effect of experimental methods on science study results in terms of communication skill.
Educational management in its strategic, managerial, and operational point of view determines the quality of education. Educational leadership-being the most important aspect of the educational management, together with the standard and human resources comprise the quality of education. The good quality of education is, therefore, determined by the leadership. It follows then that good performance of leadership brings about the standard as well as human resources of education. Effective leadership in education is thought to be able to realize these standard and resource, which further support or improve the quality of education. Consequently, strong commitment on the parts of the educational enterprise to realize the expected results is a must.
Efforts to accelerate the reduction of the Maternal Mortality Rate (MMR) can be carried out by ensuring that every mother is able to access quality maternal health services. Audiovisual media is one of the extension media that stimulates the senses of sight and hearing so as to increase mother's knowledge about the basic needs of pregnant women. This study aims to determine the effect of counseling with audiovisual media on the level of knowledge of mothers about the basic needs of pregnant women. The type of research used is a quasi-experimental research design non equivalent control group design. The sampling technique in this study used a consecutive sampling technique, as many as 32 respondents in the experimental group and 32 respondents in the control group. The statistical test used was the Wilcoxon test and the Mann Withney U-Test. From the results of the Wicoxon test in the two treatment groups, it was found that the p value (Asymp. Sig 2-tailed) was 0.000<0.05 so it could be concluded that there were significant differences in the extension group with audiovisual media and the extension group with leaflet media. The results of the analysis of the Mann Withney U-Test showed the largest p-value of 0.003<0.05 so it can be concluded that audiovisual counseling is more effectively used to increase mother's knowledge about the basic needs of pregnant women compared to leaflet media.
ABSTRAKMinyak kelapa murni, atau lebih dikenal dengan Virgin Coconut Oil (VCO), adalah modifikasi proses pembuatan minyak kelapa sehingga dihasilkan produk dengan kadar air dan kadar asam lemak bebas yang rendah, berwarna bening, berbau harum, serta mempunyai daya simpan yang cukup lama yaitu lebih dari 12 bulan. Virgin coconut oil mengandung asam laurat CH3(CH2)10COOH 50% dan asam kaprilat CH3(CH2)6COOH 7%. Kedua asam ini merupakan asam lemak jenuh rantai sedang yang mudah dimetabolisir dan bersifat anti mikroba. Di dalam tubuh, asam laurat menjadi monolaurin, sedangkan asam kaprilat menjadi monokaprin (Sutarmi, 2006). Monolaurin adalah monogliserida antiviral, antibakteri dan antiprotozoal yang digunakan oleh sistem kekebalan manusia dan hewan untuk menghancurkan virus-virus pelindung lemak, seperti HIV, herves, influenza berbagai bakteri patogen. Asam kaprat yang juga berfungsi sebagai zat kekebalan tubuh ketika diubah menjadi monokaprin di dalam tubuh manusia atau hewan. Monokaprin memiliki efek antiviral terhadap HIV dan herpen simplex serta bakteri yang tertular melalui hubungan seks (Novarianto, 2007). Berdasarkan hal tersebut, maka dapat dikatakan bahwa minyak ini memiliki banyak manfaat sehingga tim PKM memandang perlu mengadakan pelatihan pembuatan minyak VCO yang diadakan di desa Danging Kabupaten Lombok Utara yang memiliki sumber daya alam yang besar yang merupakan desa terdampak bencana gempa tahun 2018 lalu. Metode observasi partisipatoris atau observasi partisipan dan praktik langsung telah dipergunakan dalam PKM ini dengan melibatkan pula Komunitas Relawan Mataram yang juga tergabung dalam Muhammadiyah Disaster Management Centre (MDMC) Nusa Tenggara Barat. Hasil capaian dan kesimpulan dalam kegiatan ini adalah a. dimilikinya pengetahuan dan pemahaman yang merupakan upaya pemberdayaan bagi para perempuan di desa ini agar memiliki ketrampilan dalam pengolahan kelapa khususnya pembuatan minyak VCO, dan b. memberikan ketrampilan yang lebih akan pemanfaatan sumber daya alam agar menjadi tambahan penghasilan atau mampu meningkatkan pendapatan (income) yang cukup potensial sebagai langkah awal membangun masyarakat yang berdayaguna. Kata kunci: kelapa; minyak VCO ABSTRACTPure coconut oil, otherwise known as Virgin Coconut Oil (VCO), is a modification of the making process which produces products with low moisture and fatty acid content that is clear, clear in color, smells good, and has a long shelf life of more than 12 months. Virgin coconut oil contains CH3(CH2)10COOH 50% lauric acid and CH3(CH2)6COOH 7% kaprilic acid. Both of these acids are medium-chain saturated fatty acids that are easily metabolized and anti-microbial. In the body, lauric acid becomes monolaurin, while kaprilic acid becomes monokaprin (Sutarmi, 2006). Monolaurin is an antiviral, antibacterial and antiprotozoal monoglyceride used by the human and animal immune systems to destroy fat-protective viruses, such as HIV, herves, influenza and various pathogenic bacteria. Kaprat acid also serves as an immune substance when converted into monokaprin in the human or animal body. Monokaprin has antiviral effects on HIV and herpen simplex as well as bacteria infected through sex (Novarianto, 2007). Based on this, it can be said that this oil has many benefits, so that the PKM team considers it necessary to hold vco oil manufacturing training which held in Danging village of North Lombok Regency which has a large natural resource that is a village affected earthquake by the 2018. Participatory observation methods or observations of participants and direct practice have been used in this PKM by involving mataram volunteer community which is also incorporated in Muhammadiyah Disaster Management Centre (MDMC) West Nusa Tenggara. The results of the achievements and conclusions in this activity are a. knowledge and understanding which is an empowerment effort for women in this village to have skills in coconut processing, especially making vco oil, and b. provide more skills for utilization of natural resources in order to be additional or able to increase income that is potential enough as the first step in building a empowered society. Keywords: coconut; VCO oil.
