A Case study was taken as a research to investigate the physical process occurred in a simple electric circuit which consists of resistance component R and inductance L with direct voltage source. The general form of series circuit is represented a differential equation of the first order to count the current transfer equation can be found by many methods, they are the first ordered solution, Euler method, the third order Runge-Kutta method, and the fort order Runge-Kutta by using Matlab program. The examinationon by using step measurement with h = 0,05 caused error value to the first order solution method = 2.79%, Euler method = 3.8%, the third order Runge Kutta method = 2.1%, the forth order Runge Kutta method = 2.26%, using step measurement h = 0.1 caused error value to the first order solution = 2.27%, Euler method = 5.23%, the third order Runge Kutta method = 2.27%, the fourth order Runge Kutta method = 1.85% and using step measurement h = 0,15 caused error value to the first order solution = 5.81%, Euler method = 22,35%, the third order Runge Kutta method = 7.19%, the forth order Runge Kutta method = 4.7%.

The development of information technology is currently very rapid, can be seen in the real world how important the use of video, such as in the field of advertising, entertainment, business and no less important in the field of education for the delivery of learning information which all require a clear and attractive display. In this study, we will examine a comparison of three video software on image quality, image sharpness, brightness and audio effects in Windows Live Movie Maker, VideoSpin and Movavi Video. The research conducted made the video using the three software on the NTSC video format, AVI file type, resolution (720x480), 4:3 Pixel ratio, Standard D1 aspect ratio (0.09), 1500 kbps bit rate, 29.97fps frame rate with Audio: Stereo Channels, 48,000 HZ sample rate, 2.2 minutes duration. The samples were taken by the HMJ activities (HIMAKOM), namely graphic science competitions, sports, the introduction of new software training students, data used by static photos. For testing, questionnaires were collected on 43 respondents, students, majoring in Computer Systems and Statistics to assess the results of the video from the three video software and then tested with Anova to find out which one was better. From the results of the calculation of respondents' data, the average respondents liked the Movavi Video software with an image quality value of 89.2, sharpness of images 88.103, audio effects 83.333 and after being tested using Anova software Movavi Video analysis was better. It was concluded in this study that Movavi Video software could be a consideration to choose from in making videos.

The purpose of this study was; to analyze the achievement of social skills of students who experienced in learning using the concept mapping. This study is expected to improve teacher performance in learning by looking at the appropriate approach to learning social studies (IPS). This type of research used is a quantitative research method in the form of quasi-experimental design with pre-test – post-test control group design. The population of this study was all grade IV elementary school students in Pattimura Cluster, Genuk Sub-District, Semarang City. The sample was selected through a purposive sampling technique, so that selected SDN Karangroto 03 class IVA as the experimental group and class IV B as the control group. Data collection techniques use non-test techniques which include interview guidelines, observation guidelines, and documentation. The results of the study indicate that; the method of concept mapping effectively increases the social skills of students in social studies learning in the fourth grade of elementary school, with the achievement of 2 indicators namely; (1) the improvement of students' social skills is in the minimum medium category based on the N-Gain test in the experimental class. The results of the N-Gain test in the experimental class are 0.32 which are classified into the medium category; and (2) the average score for concept mapping is in the minimum, medium category. The results of the average making of the concept mapping by students are 78% in the high category.

Pada saat ini perkembangan sistem informasi berbasis mobile sangat pesat, seperti informasi pembelajaran yang menyampaikan modul pembelajaran dari berbagai disipilin ilmu seperti matematika, fisika, penggunanaan sofware, juga wisata, perbelanjaan online dan masih banyak lagi. Dari modul-modul pembelajaran tersebut dapat juga memberi informasi tentang geosains yang dapat menginformasikan ilmu kebumian.Penelitian aplikasi mobile berbasis android ini bertujuan untuk memberikan pengetahuan tentang ilmu Kebumian (Geosains) kepada seluruh masyarakat luas. Geosains terdiri dari beberapa disiplin ilmu seperti Geologi, Klimatologi, Hidrologi, dan Astronomi, yang dapat dioperasikan pada gadget dengan OS android. Dalam pembuatan sistem digunakan MIT App Inventor 2 dengan dukungan software desain grafis Corel Draw X4 dan Adobe Photoshop CS6. Secara garis besar penelitian ini dilakukan pada empat tahap utama, yaitu analisa kebutuhan, desain (perancangan), pembuatan (implementasi), dan pengujian (test). Namun disamping itu, tetap dilakukan support atau pemeliharaan (maintenance) aplikasi dan akan diperbarui (update) secara berkala untuk pengembangannya.Hasil yang didapatkan bahwa aplikasi mampu berjalan dihampir semua versi android dari versi 4.0 Ice Cream Sandwich hingga 6.0 Marsmallow, meskipun pada android Kitkat dan Lollipop terdapat sedikit trouble berupa berubahnya posisi button dan teks pada tampilan aplikasi, namun hal ini tidak mempengaruhi performa sistem. Untuk memdapatkan tampilan terbaik direkomendasikan menggunakan android versi Jelly Bean dan Marsmallow. Hasil akhir aplikasi (file apk) dapat diunduh melalui layanan penyedia aplikasi secara online dan bersifat gratis.

Gizi buruk adalah kondisi tubuh terparah yang mengalami kekurangan gizi dalam kurun waktu yang lama (menahun). Kasus gizi buruk pada anak atau balita di Indonesia sangat memprihatinkan. Banyaknya kasus gizi buruk bisa dilakukan pemetaan dengan Sistem Informasi Geografis (SIG). Teknologi SIG yang sangat popular adalah menggunakan Google Maps API. Dalam penelitian ini dilakukan pembuatan sistem untuk mengimplementasikan SIG ke dalam web dan mobile di Dinas Kesehatan (Dinkes) Kota Yogyakarta dan menyajikan data persebaran gizi buruk balita dalam bentuk maps di Mobile Android. Pengumpulan data awal adalah dengan dengan survey ke Dinkes Kota Yogyakarta untuk mendapatkan data gizi buruk balita. Pada tahap perancangan sistem, penulis melakukan rancangan Database, Program Web dan Program Mobile. Pembuatan program menggunakan 2 tahap yaitu dengan membuat website menggunakan HTML, CSS, dan Javascipt. Dan pembuatan mobile menggunakan Monaca untuk membangun aplikasi hibrida HTML5 untuk ios, Android, dan Windows. Tahapan dalam pengujian dilakukan dengan menguji Load Time Page website di browser Mozila Firefox, Google Chrome, Microsoft Edge, dan Safari. Dan pengujian mobile di versi android 4.0 (Kitkat) sampai dengan versi 9.0 (Pie). Hasil penelitian ini menghasilkan sebuah program aplikasi berbasis mobile dan website untuk membantu petugas Dinkes Kota Yogyakarta dalam mengontrol dan menekan gizi buruk dan membantu Pengguna mobile (user) dalam melihat sebaran puskesmas yang menangani gizi buruk di wilayah Kota Yogyakarta dalam bentuk maps serta memberikan informasi mengenai jumlah data gizi buruk dan memberikan informasi cara pencegahan gizi buruk.
