Abstract

Cockroaches (Periplaneta americana) are often found in homes, restaurants, hotels, hospitals, warehouses, offices, libraries, and others. The existence of these highly dynamic animals is suspected of causing nosocomial infections at the hospitals and acting as vectors and hosts associated with bacteria carried on its feet. This research aims to analyze the sensitivity of Gram-negative bacteria isolated from Cockroach feet in the hospital and residential areas in Palu City against some antibiotics. This research is an explorative laboratory experiment research, with the method of bacteria identification, isolation and antibiotic test using standard procedure "The Bauer-Kirby". The results of bacterial identification in three areas of the Palu Hospital are Klebsiella ozaenaeSalmoella arizonae, Salmonella sp. Escherichia coli, Salmonella cholerae-suis and Salmonella simultans, while the bacteria from the residential area, Escherichia coli, Klebsiellapneumoniae, Proteus vulgaris, Salmonella arizonae, and Proteus mirabilis. The results of bacterial sensitivity tests on five antibiotics showed that all of these bacteria were resistant to the antibiotics of Vancomycin, Chloramphenicol, and Amoxycillin, but were still sensitive to Ciprofloxacin and Ofloxacin.

Abstract

Shorea leprosula Miq. is a member of the Dipterocarpaceae which has a high genetic diversity. In Indonesia, this species is naturally spread on the islands of Sumatra, Kalimantan and Maluku.  The purpose of this paper is to investigate the diversity of S. leprosula seedlings at 6 months of age from three populations in East Kalimantan. The experimental design used was Complete Randomized Design (CRD) with 10 seeds for each mother tree from three populations (Muara Wahau 15 mother trees, Berau 12 mother trees and Kenangan 20 mother trees).In this study the mother tree is nested in the population. The result of variance analysis showed that the population sources and mother tree had significant effect on high growth, stem diameter and the index of robustness of S. leprosula seedlings at 6 months of age. Kenangan  population and Muara Wahau population are the best population in high growth and stem diameter, while the best robustness index is occupied by Berau population. The mother trees were separated in 19 groups of differences on high growth characters, 15 groups of differences in stem diameter growth characters and 12 groups of differences in robustness index characters.  The best high growth is occupied by 4 mother trees with a range of 57.00 - 62.64 cm, the best stem diameter is occupied by 5 mother trees with a range of 4.76 - 5.47 mm and the best robustness index is occupied by 14 mother trees with values range 7.66 - 10.12.

Abstract

Senyawa nitrogen (N) bagi semua tanaman sangat diperlukan untuk pertumbuhan dan produksi, termasuk tanaman tembakau. Metabolisme senyawa N dalam tanaman sangat terkait dengan metabolisme karbohidrat.   Proses fotosintesis yang terjadi di daun menyediakan energi untuk proses asimilasi karbon (C) dan Nitrogen (N). Dalam asimilasi N selain memerlukan energi,  juga memerlukan kerangka C yang disediakan oleh metabolism karbohidrat, termasuk sukrosa.Sintesis sukrosa di daun sangat ditentukan oleh besarnya aktivitas  enzim sucrose phosphate synthase (SPS). Tujuan penelitian ini adalah untuk mengetahui pengaruh transformasi gen SPS pada tanaman tembakau terhadap metabolisme senyawa N.  Proses transformasi gen SPS yang telah dikonstruk pada plasmid pBI121 menggunakan  Agrobacterium tumefaciens  LBA 4404. Hasil penelitian menunjukan bahwa transformasi gen SPS  mempengaruhi aktivitas enzim nitrat reduktase (NR) dan glutamine synthetase (GS). Aktivitas NR dan kandungan nitrat pada tembakau transgenik galur 3, 13 dan 17 lebih rendah dibandingkan kontrol. Sebaliknya aktivitas GS pada ketiga tembakau transgenik  lebih besar dibandingkan kontrol.  Kata kunci : SPS, Nitrogen, GS, NR, Transformasi.
