Purpose To study the direct effect on the first mustard cropping and the residual effect of three kinds of vermicompost on the productivity of the second, third, fourth Pak-Coi mustard sequential cropping. Method A field experiment was conducted for four sequential planting periods of mustard Pak-Coi in silty clay Inceptisol. The experiment used a factorial randomized block design with two factors. Factor I comprised three kinds of vermicompost with three types of bedding materials; V1-spent mushroom waste, V2-coconut husk, and V3-sugarcane trash, while factor II comprised four different application rates: 5, 10, 15, and 20 t ha −1. From these two factors, there were 12 treatments plus one control treatment (without vermicompost application). Results Application of vermicompost increased soil NPK content. The highest nutrient uptake was also found in the residual effect for the second cropping. Nutrient uptake of the third and fourth mustard cropping had a decreasing trend. The highest yield on the first cropping was found in the application of vermicompost V2 and V1 with the application rates of 10-15 t ha −1. In the second cropping, the productivity increased, whereas the third and fourth sequential cropping decreased in the vermicompost V1 and V2, whereas in the vermicompost V3 the productivity of the third and fourth cropping was slightly increased. Conclusion The application of vermicompost to organic farming provides nutrient availability in four mustard subsequent planting periods. Differences in the dynamics of nutrient availability, nutrient uptake and crop yields are affected by the vermicompost materials used.
Dari segi sarana dan prasarana, 109 MTs di Kabupaten Bojonegoro sudah memiliki sarana-prasarana yang memadai, di beberapa madrasah fasilitas Internet juga telah tersedia, namun dalam penggunaanya belum optimal. Para guru masih sangat jarang yang memanfaatkan komputer itu untuk tujuan peningkatan pembelajaran apalagi menggunakan media pembelajaran berbasis Powerpoint dengan berbagai aplikasinya ,pengabdian ini dilakukan untuk meningkatkan pengetahuan dan meningkatkan keterampilan guru-guru bahasa Arab MTs di Bojonegoro tentang konsep media pembelajaran berbasis powerpoint, materi yang dikembangkan adalah media pembelajaran bahasa Arab dan pembuatan video pembelajaran melalui android, metode yang digunakan adalah pelatihan dan pendampingan. Hasil pelatihan ini menunjukkan bahwa keterampilan para guru cukup meningkat dengan indikator bahwa produk luaran pelatihan telah memenuhi standar media yang menarik serta berpotensi dapat mempercepat pencapaian kompetensi siswa dalam pembelajaran bahasa arab.Kata kunci— Media Pembelajaran, Pembelajaran inovatif, Bahasa Arab, Powerpoint AbstractIn terms of facilities and infrastructure, 109 MTs in Bojonegoro already have adequate infrastructure, in some madrasah Internet facilities are also available, but the use is not optimal yet. Teachers are still very rarely using the computer for the purpose of improving learning especially using Powerpoint-based learning media with a variety of applications, this dedication is done to increase knowledge and improve the skills of Arabic MTs teachers in Bojonegoro about the concept of powerpoint-based learning media, the material developed is a medium for learning Arabic and making learning videos through Android, the method used is training and mentoring. The results of this training show that the skills of teachers have improved considerably with indicators that the training output products have met attractive media standards and can potentially accelerate the achievement of student competencies in learning Arabic.Keywords—Learning Media, Innovative Learning, Arabic, Powerpoint
PPandemi covid-19 sudah berlangsung selama 9 bulan, dengan jumlah yang terpapar terus meningkat. Berbagai upaya dilakukan pemerintah untuk mengurangi penyebaran wabah tersebut, salah satunya dengan meluncurkan Aplikasi PeduliLindungi. PeduliLindungi ditetapkan sebagai aplikasi yang membantu melakukan Tracing, Tracking, Fancing melalui infrastruktur, sistem dan aplikasi telekomunikasi yang terhubung dengan data center dalam negeri. Penelitian ini bertujuan untuk mengetahui perlindungan data pribadi bagi pengguna Aplikasi PeduliLindungi. Metode Penelitian melalui studi literatur, dengan data sekunder, menggunakan bahan hukum primer, sekunder, tersier, dengan mengkaji berbagai peraturan, mengingat sampai saat ini belum ada undang-undang yang mengatur tentang perlindungan data pribadi. Hasil penelitian menunjukkan Perlindungan data pribadi pengguna aplikasi ini didasarkan pada peraturan yang mengatur tentang Teknologi Informasi dan Komunikasi, Kesehatan, dan Pelaksanaan administrasi Kependudukan, meskipun pemerintah memberikan jaminan keamanan bagi pengguna PeduliLindungi, namun sampai saat ini pengguna aplikasi PeduliLindungi masih kurang diminati. Harapan kedepannya semakin banyak yang mengunduh PeduliLindungii, sehingga dapat menekan angka penyebaran covid-19. Selain itu pentingnya segera disahkan undang-undang perlindungan data pribadi untuk memberikan kepastian hukum.
Abstrak: Telah dilakukan penelitian pengembangan media pembelajaran pada materi momentum dan impuls berbasis mobile learning, dengan tujuan untuk menganalisis kelayakan media pembelajaran berbasis mobile learning yang dikembangkan, peningkatan kemampuan berpikir kritis siswa, dan efektivitas media yang digunakan dalam pembelajaran. Jenis penelitian yang digunakan ialah pengembangan yang mengacu pada model pengembangan ADDIE yaitu Analysis, Design, Development, Implementation, dan Evaluation. Penelitian ini dilakukan di SMA Negeri 5 Purworejo dengan subyek uji coba berjumlah 29 siswa. Instrumen yang digunakan dalam penelitian ini adalah lembar validasi, angket respon siswa, tes hasil belajar, dan lembar keterlaksanaan pembelajaran. Berdasarkan penelitian diperoleh data hasil validasi media pembelajaran berbasis mobile learning dari empat validator mendapatkan nilai secara keseluruhan sebesar 3,56, termasuk dalam kategori baik dan layak digunakan dalam pembelajaran. Peningkatan kemampuan berpikir kritis tahap penerapan diperoleh N-gain 0,61 dan termasuk kategori peningkatan sedang. Efektivitas media yang digunakan dalam pembelajaran ditunjukkan dengan angket tanggapan siswa mendapatkan persentase keseluruhan 84% dan termasuk kategori baik, serta ditunjukkan dengan lembar keterlaksanaan pembelajaran dengan persentase keseluruhan adalah 95,8% dan termasuk kategori sangat baik. Sehingga media pembelajaran berbasis mobile learning dapat digunakan sebagai media alternatif dalam pembelajaran untuk membantu meningkatkan kemampuan berpikir kritis siswa. Abstract: Research on the development of learning media has been carried out on momentum material and impulse based on mobile learning to determine the feasibility of mobile learning-based learning media developed, improvement of students' critical thinking skills, and the effectiveness of the media used in learning. The type of research used is a development that refers to the ADDIE development model, namely Analysis, Design, Development, Implementation, and Evaluation. This research was conducted in SMA Negeri 5 Purworejo with the subject of the trial amounting to 29 students. The instruments used in this study were validation sheets, student response questionnaires, learning outcomes tests, and learning implementation sheets. Based on the research, data obtained from the validation of mobile learning-based learning media from the four validators obtained an overall score of 3.56, included in the category of good and appropriate for use in learning. The increase in critical thinking skills in the application stage was obtained by N-gain of 0.61 and included in the medium improvement category. The effectiveness of the media used in learning is shown by questionnaires. Students' responses get an overall percentage of 84% and are included in the good category, and are indicated by the learning implementation sheet with an overall percentage of 95.8% and including very good categories. So that learning media based on mobile learning can be used as alternative media in learning to help improve students' critical thinking skills.
