Abstract

This research was conducted to: (1) design a Schoology-based blended learning media for Basic Physics I course on the topics of vector quantity, linear motion, and translational dynamics, (2) describe the validity of the product, (3) describe the product’s effectiveness in enhancing students’ conceptual understanding and problem solving skills, and (4) describe students’ responses towards the media and blended learning model. The development procedures employed were ADDIE model which consisedt of five stages: analysis, design, development, implementation, and evaluation. In development stage, the assessment had been conducted by two experts to assess validity of media both in content and construct aspects. The results showed that the validities in content aspect and construct aspect were “very good” and “good”, respectively. The results from classroom implementation revealed the effectiveness of the product in enhancing students’ conceptual understanding and problem solving skills. Students’ responses towards the product’s utility, attractiveness, and easiness as blended learning media were also positive. The conclusion was that the media was valid and effective as blended learning media of Basic Physics I course.

Abstract

One of the renewable energy storage systems that can be used today is the aluminum ion battery. In this study, aluminum foil was used as anode, polyetylene polyprophylene (PE/PP) as separator, electrolyte from AlCl3/[EMIm]Cl and graphite coated corncob, an activated charcoal, as cathode. Coating method of cathode materials was done by mixing both graphite and activated charcoal with varied composition 1:0.5, 1:1, 1:1.5, and 1:3. The coating process began by mixing the graphite and corncob with ethanol as a solvent for six hours, then heating in an oven at 80 °C for three days, gradual drying in a furnace at 350 °C for five hours and sintering at 600 °C for six hours. From this research, SEM results showed that carbon particles were evenly distributed, with spherical particles. The spherical shape was the main requirement of carbon formation in order to produce high energy. Based on the results, battery potential was 2.54 V with average of optimal capacity at a ratio of graphite and corncob activated charcoal 1:1.5 was 83.067 mAh/g. The highest efficiency was also at a ratio of 1:1.5 of 97.20%, because at this ratio, there was an increasing in percentage of element C 91.74%, greater than the percentage of element C on the other three cathode samples.Salah satu sistem penyimpan energi terbarukan yang bisa digunakan saat ini adalah baterai ion aluminium. Pada penelitian ini digunakan aluminium foil sebagai anoda, polyetylene polyprophylene (PE/PP) sebagai separator, elektrolit menggunakan AlCl3/[EMIm]Cl dan grafit terlapisi arang aktif tongkol jagung sebagai bahan katoda. Metode pelapisan bahan katoda dilakukan dengan mencampurkan grafit dan arang aktif dengan variasi komposisi 1:0,5, 1:1,1:1,5 dan 1:3. Proses pelapisan diawali dengan pencampuran grafit dan arang aktif tongkol jagung dengan ethanol sebagai pelarut selama enam jam kemudian pemanasan di oven pada suhu 80oC selama tiga hari, pengeringan bertahap di furnace pada suhu 350oC selama lima jam dan sintering pada suhu 600oC selama enam jam. Dari penelitian ini didapatkan hasil SEM menunjukkan bahwa partikel karbon terdistribusi merata, dengan bentuk partikel bulat (sphare).Sampelberbentuk bulat atau sphere merupakan syarat utama pembentukan karbon supaya dapat menghasilkan energi tinggi. Berdasarkan hasil uji baterai diperoleh potensial sebesar 2,54 Volt dengan rata-rata kapasitas optimal terjadi pada rasio grafit dan arang aktif tongkol jagung 1:1,5 sebesar 83,067 mAh/g. Efisiensi tertinggi juga terjadi pada rasio 1:1,5 sebesar 97,20%. Hal ini karena pada rasio 1:1,5 terjadi peningkatan persentase unsur C yakni 91.74% lebih besar dari persentase unsur C pada tiga sampel katoda yang lainnya.

Abstract

Penggunaan pestisida yang tidak terkontrol akan mengganggu agroekosistem pertanian dan mencemari lingkungan. Jumlah pestisida yang beredar di Indonesia tahun 2006 terdaftar sebanyak 1336 formulasi, 2008  sebanyak 1702 formulasi, 2010 sebanyak 2048 formulasi, 2011 sebanyak 2247 formulasi. Di dalam tanah, karbon aktif peranan sebagai shelter atau rumah untuk mikroorganisme. Pori-pori kecil pada karbon aktif digunakan sebagai tempat tinggal bakteri, sedangkan pori besar dan retakan (cracks) digunakan sebagai tempat berkumpul. Penelitian dilakukan di Laboratorium Mikrobiologi Pusat Penelitian Biologi LIPI Cibinong Mei 2011 s/d Agustus 2011. Tujuan penelitian adalah menyeleksi bakteri  dalam tanah yang berpotensi mendegradasi residu insektisida yang bersifat persistent organic poluttants  (POPs).  Isolasi dan karakterisasi mikroba pendegradasi POPs dilakukan  dengan tiga tahapan, yaitu (1) Isolasi dan identifikasi mikroba pendegradasi POPs, (2) Uji karakteristik pertumbuhan isolat pada berbagai jenis POPs, dan  (3) Penetapan residu insektisida POPs hasil kultur. Hasil terdapat 7 (tujuh) isolat yang mampu mendegradasi senyawa POPs, Lima isolat bersifat gram positif (BOB1, BOB2, BOB3, BOB4, BOB5) efektif untuk mendegradasi POPs berbahan aktif: lindan, heptaklor, DDT, dan dieldrin, sedangkan  dua isolat bersifat gram negatif (BOB6 dan BOB7) efektif untuk mendegradasi POPs berbahan aktif aldrin.  Kata Kunci: Arang Aktif, Senyawa POPs, Bakteri Pendegardasi

Abstract

Spiritual intelligence is very much needed in human life. Because spirituality can be used to stem our bad behavior to become better. Spiritual intelligence is soul intelligence that helps a person to develop himself as a whole through creating the possibility to apply positive values. There is more value for every human being in developing their mindset so that they are able to develop and think clearly to consider, decide and face things by focusing on the problems they face and brilliant solutions. This reality can be seen from the dynamics of diverse people's lives, both in terms of religion, ethnicity, language and culture. The existing diversity can actually be a great potential for the nation's progress. However, on the other hand, it also has the potential to cause various kinds of problems if it is not managed and developed properly. This research uses a descriptive qualitative approach. Data collection uses observation, interviews and documentation. The important thing that is needed is to design some educational curriculum material content for students so that they can accept other people as equals and respect their religion, culture and ethnic differences. Therefore, a curriculum model with a variety of themes is a curriculum model that is highly recommended.
