Abstract

Implementation of the learning process at SMAN 1 KEREK still uses conventional approach based learning. Learning methods such as lectures and question and answer still apply to the school. If this conventional approach-based learning is still applied in the modern era, it is feared that it will affect student's learning outcomes with 65% of the learning completeness score and KKM (70) which means that KKM has not reached the value of KKM. The currently used Student Worksheet is still simple in terms of materials, drawings and language used, so the need for the development of Student Worksheet (LKS) based on the Scientific Approach.In this environmental change and waste recycling materials LKS development uses Borg and Gall development methods. The purpose of this research is to find out the result of validity test of Student Worksheet based on scientific approach on environmental change and waste recycling materials and to improve student learning result SMAN 1 KEREK. The instrument used for this research is the questionnaire. Validity test results obtained from media experts with an average value of 83.1%, and from material experts obtained an average of 84% with criteria very valid and fit to be used as teaching aids, thus from the validity test results can be concluded that product development of Student Worksheet (LKS) based on biological approaches scientifically feasible to use and able to improve student learning outcomes SMAN 1 KEREK.

Abstract

ABSTRAK   Tujuan penelitian ini adalah untuk mencari kondisi dalam menumbuhkan  kultur Alteromonas luteoviolaceus dan mengisolasi DNA genomiknya sebagai langkah awal dalam penelitian dengan tema Identifikasi Gen Halogenase dari A. luteoviolaceus Penghasil Antibiotik Penta-brompseudilin Secara Hibridisasi. Penelitian ini bersifat eksploratif dengan disain penelitian faktor tunggal yang dianalisis secara kualitatif. Penumbuhan  A. Luteoviolaceus dilakukan dalam medium M1+ yang dimodifikasi dan dalam Difco Marine Broth 2216. Isolasi DNA genom A. luteoviolaceous dengan dua prosedur, yaitu (1) dengan prosedur salting out (Pospiech and Neuman, 1995) dan (2)  dengan  prosedur Kirby mix dari (Hopwood et al.,1985). Hasil penelitian menunjukkan bahwa marine bakteri A. luteoviolaceous dapat ditumbuhkan dalam medium M1+ modifikasi pada 27-30oC selama 2-7 hari sedangkan dalam Marine Broth 2216 pada hari ke 3 terjadi penurunan pertumbuhan. Pertumbuhan dapat dipercepat dengan meletakkan spiral pada dasar Erlenmeyer yang digunakan. Isolasi DNA genom Actinoplane sp berhasil dilakukan dengan prosedur Kirby mix yang kulturnya ditumbuhkan dalam medium cair M1+ modifikasi selama maksimum 2 hari. Dengan waktu inkubasi lebih dari 2 hari DNA genom tersebut sulit diperoleh. Meskipun dengan waktu inkubasi sampai 2 hari DNA genom juga tidak diperoleh jika diisolasi dengan prosedur salting out. Isolasi DNA genom Actinoplane sp juga tidak memperoleh hasil bila ditumbuhkan pada Difco Marine Broth 2216 selama 2 hari baik dengan prosedur salting out maupun Kirby mix.

Abstract

Penganekaragaman Pangan merupakan upaya meningkatkan Ketersediaan Pangan yang beragam dan berbasis pada potensi sumber daya lokal untuk mendukung ketahanan pangan dan meningkatkan kesejahteraan masyarakat. Penganekaragaman pangan salah satunya dilakukan melalui pengembangan diversifikasi usaha tani dan perikanan. Pengembangan dari salah satu sektor saja tentunya membutuhkan lahan yang lebih luas, padahal saat ini ketersediaan lahan di berbagai daerah semakin berkurang. Hal ini terjadi karena peralihan fungsi lahan yang banyak digunakan untuk industri dan perumahan. Kebutuhan bahan pokok pangan, seperti beras sebagai sumber karbohidrat terus meningkat sejalan dengan peningkatan jumlah penduduk. Selain itu kebutuhan ikan sebagai sumber protein juga semakin tinggi sejalan dengan meningkatnya kesadaran masyarakat akan pemenuhan gizinya. Untuk itu perlu adanya inovasi teknologi yang dapat mengakomodasi kedua jenis kebutuhan tersebut, dengan salah satu caranya yaitu penerapan minapadi. Penelitian deskriptif ini bertujuan untuk mengetahui keuntungan-keuntungan yang didapatkan dalam penerapan minapadi dibandingkan dengan non minapadi berdasarkan literatur dan penelitian-penelitian terdahulu.

Abstract

Indonesia merupakan negara dengan wilayah perairan lebih besar daripada wilayah daratan. Oleh sebab itu, komoditas perikanan merupakan salah satu komoditi ekspor terbesar di Indonesia. Salah satu komoditas perikanan Indonesia yaitu cumi-cumi. Pada umumnya pemanfaatan cumi-cumi hanya dagingnya, sedangkan bagian cangkang internalnya tidak terpakai dan menjadi limbah. Cangkang internal ini dapat diekstrak menjadi kitosan. Kitosan merupakan polimer yang bisa digunakan sebagai antibakteri. Tujuan penelitian ini adalah untuk mengekstrak kitosan dari cangkang internal cumi-cumi dan menguji aktivitas antibakteri kitosan cangkang internal cumi-cumi (Loligo sp.) terhadap bakteri S. aureus dan E. coli. Metode yang digunakan adalah metode eksperimental dengan Rancangan Acak Lengkap dengan 3 perlakuan dan 2 kali pengulangan. Metode pengujian aktivitas antibakteri menggunakan paper disk diffusion method dengan konsentrasi 0%, 1% dan 2%, kemudian diinkubasi selama 24 jam. Kitosan dari cangkang internal cumi-cumi menunjukkan aktivitas antibakteri terhadap bakteri S. aureus dan E. coli.
