This study aims to develop a STEM-based Student Worksheet (LKPD) through Guided Inquiry to Improve Students' Science Process Skills. This research and development method refers to the Borg & Gall ...model up to the 8th stage, namely a trial use that has been adapted to research needs, namely developing LKPD and seeing an increase in students’ science process skills after using LKPD in learning activities, with research subjects in class XI IPA 5 and XI. IPA 3, each totaling 24 students. The results obtained are: 1) the validation of the LKPD that has been developed is "very valid" with the percentage of material experts at 82.36% and the percentage of media experts being 82.44%; 2) the feasibility of the developed LKPD is very feasible with a percentage of 95.43%; 3) The LKPD developed is declared practical because the response questionnaires from students are categorized as practical 4) the results of students' responses to the use of "very good" trials with a percentage of 87.33%; 5) The effectiveness of LKPD is seen from the achievement of students' science process skills with an N-Gain value of 0.78 or with a percentage of 78% overall very good and increasing in every meeting. It was concluded that the development of STEM-based LKPD through Guided Inquiry was valid and feasible and could be used in the Physics learning process to improve Students' Science Process Skills on Thermodynamic Materials.
Melalui perkembangan teknologi Internet, kini komunikasi tidak hanya terjadi secara tatap muka, namun juga bermedia komputer atau dikenal dengan istilah computer mediated communication (CMC). ...Perkembangan teknologi diikuti juga dengan perkembangan beragam platform media sosial yang banyak digunakan sebagai media komunikasi. Kemunculan media sosial tersebut banyak dimanfaatkan oleh komunitas sebagai sarana komunikasi dan interaksi, hal tersebut mendorong terbentuknya komunitas dalam ranah virtual seperti Komunitas HAMUR yang berada di Yogyakarta yang memanfaatkan grup percakapan pada media sosial Line sebagai media komunikasi komunitas. Tujuan dari penelitian ini adalah untuk mengetahui pola komunikasi virtual, aturan komunikasi dan proses komunikasi komunitas HAMUR. Penelitian ini menggunakan metode penelitian kualitatif dengan menggunakan pendekatan etnografi virtual. Pengumpulan data dilakukan melalui tahap wawancara kepada 5 informan dan observasi terhadap grup percakapan komunitas yaitu “HAMURInspiring”. Hasil penelitian memperoleh bahwa adanya kesamaan identitas antar anggota komunitas HAMUR yaitu berasal dari keluarga broken home (keluarga tidak harmonis). Pada aturan komunikasi, komunitas HAMUR tidak memiliki aturan tertentu secara tertulis yang mengatur anggota dalam berkomunikasi. Pada proses komunikasi secara primer terdapat perbedaan bahasa antar anggota komunitas dalam berkomunikasi, pada proses komunikasi sekunder media Line dianggap membantu menghubungkan antar anggota komunitas yang terpisah jarak untuk berkomunikasi. Aspek-aspek tersebut berhubungan dengan pola komunikasi virtual yang terbentuk pada komunitas HAMUR, pola komunikasi dari komunitas HAMUR adalah pola komunikasi semua arah sehingga setiap anggota dapat bebas melakukan komunikasi dengan anggota lainnya.
In Electrochemotherapy, Electrogenetherapy, and Transdermal Drug Delivery, leading experts comprehensively review all aspects of the delivery of therapeutic molecules to cells using electrical ...impulses-i.e., the extraordinarily promising new areas of electrogene therapy, electrochemotherapy, and transdermal drug delivery. Their survey ranges from outlines of the basic physical principles that govern cell permeabilization by pulsed electric fields, to descriptions of the current state-of-the-art in instrumentation and electrodes, to summaries of preclinical and clinical trial results. The authors focus on drug, gene, and transdermal delivery techniques, providing detailed examples of drug delivery using electric fields from a variety of pulse generators and electrodes. The protocols cover almost every variation in procedure and/or apparatus so that investigators can readily identify the method needed for their own work, or adapt one to their particular purposes. Comprehensive and authoritative, Electrochemotherapy, Electrogenetherapy, and Transdermal Drug Delivery provides entré to an immensely practical set of in vivo electroporation techniques, including electrogene therapy, electrochemotherapy, and transdermal drug delivery-techniques holding great promise for all those working toward better therapies for in cancer, metabolic diseases, and vaccination.
