Abstract

This study focuses on elucidation of the perception of actors in education toward the use of technology in the 2013 Indonesian Education Curriculum (C-13). The study was done at SMA Plus YPHB and SMAN 4 Bogor, high schools located in Bogor City, West Java, Indonesia. The specific policy that underlies this study is the Regulation of Ministry of Education and Culture No.70/2013 in the point of completion mindsets No. 6 about the shift from single tool learning to multimedia-tool based learning. This paper integrates mixed methods?qualitative and quantitative methods, which use questionnaires and interview by incorporating Extended Technology Acceptance Model (TAM) using path regression analyses. The subjects of the research are teachers and students in the schools, an education practitioner, and an educational policy advisor. Furthermore, the assessment was done toward the perceptions of educational technology infrastructure, such as computers/laptops, projectors, speaker, Internet, software application and mobiles. The results show that Perceived Usefulness (PU) is better shaped by Perceived Ease of Use (PEU), Attitude Toward Using (ATU) is influenced by PEU, and Intention to Use (IU) is significantly affected by ATU. However, the external variables are novel for teachers and students. For teachers, the external variables do not determine PU, yet age influences PU for students. Thus, teachers and students show good intention to use the technology providing they embrace positive attitudes in using it.

Abstract

AbstrakMangrove memiliki biodiversitas mikroorganisme salah satunya bakteri.Bakteri  dari lumpur mangrove ini mempunyai kinerja penurunan hidrogen sulfida, karena lumpur mangrove memiliki kandungan hidrogen sulfida didalamnya yang memungkinkan adanya aktifitas penguraian oleh bakteri aerobik. Isolasi dilakukan menggunakan medium Thiosulfat Mineral Medium. Isolat yang tumbuh dilakukan dengan pengamatan makroskopis. Isolat terpilih akandilakukan pengamatan mikroskopik, uji katalase dan uji motilitas. Isolat juga akan diuji kinerja penurunan sulfida. Isolat dengan kinerja penurunan sulfida terbaik akan dilanjutkan untuk uji sekuensing 16S rRNA. Hasil sekuensing menunjukkan isolat dari lumpur mangrove yang memiliki kinerja penurunan sulfida terbaik dengan nilai 30,58% adalah bakteri spesies Bacillus aryabhattaiKata kunci : mangrove, sulfida,bakteri, aerobik, BacillusAbstractMangroves have a biodiversity of microorganisms, one of which is bacteria. The bacteria from this mangrove mud has the performance of reducing hydrogen sulfide because the mangrove mud contains hydrogen sulfide, which allows for aerobic bacteria to decompose. Isolation was carried out using Thiosulfate Mineral Medium. Moreover, the growing isolates were carried out by macroscopic observation. Selected isolates will be subjected to microscopic observation, catalase test and motility test. The isolates will also be tested for their sulfide reduction performance. The isolates with the best sulfide reduction performance will be continued for 16S rRNA sequencing assays. The sequencing results showed that isolates from mangrove mud that had the best sulfide reduction performance with a value of 30.58% were bacteria species Bacillus aryabhattai. Keywords: mangrove, sulfide, bacteria, aerobic, Bacillus
