Judul: Analisis Respon Toleransi Padi Nipponbare Transgenik Terhadap Salinitas Tinggi
Abstrak: The global climate change causing concerns and challenges ahead in improving the productivity of rice continuously. Increasing the temperature of the earth causes increased salinity on land around the beach due to rising sea levels. Anticipatory measures and strategically to deal with these changes is improve the nature of rice tolerant to high salinity through genetic engineering approaches. OsDREB1A and OsERF1 is a specific transcription factor genes of plants that a role in inducing other genes that responsible regulate response to stress salinity. This study aims to analyze response tolerance transgenic rice Nipponbare- OsDREB1A and Nipponbare-OsERF1 to high salinity. Analysis carried out by polymerase chain techniques reaction (PCR) using primers HPT and for selection used NaCl concentration 25 mM and 150 mM. Results treatment of 25 mM NaCl stress obtained 38 plants positive transgenic gene contains factors OsDREB1A and OsERF1 transcription of 48 plants putative transgenic with high growth characteristics of plants and root length was better than the wild type. Results selection of 150 mM NaCl stress obtained 23 plants positive transgenic of 29 plants putative transgenic with characteristics can lead a normal life when all types of wild rice dead.

Judul: Karakterisasi Molekuler Tanaman Padi Nipponbare Transgenik 35S::OsERA1 yang Toleran Kekeringan
Abstrak: Drought is one of the factors that resulted in the growth and development of rice plants inhibited. One way to overcome this problem is use of transgenic rice plants that are tolerant to drought. The success of the transformation using OsERA1 gene in Nipponbare genotype rice requires further confirmation of tolerance to drought stress. The aim of this study was to obtain transgenic Nipponbare genotype rice contain gene 35S::OsERA1 drought tolerant, know the number of gene copies, and compare the contents and empty seeds with control. The evaluation of drought the tolerance was performed using Standard System Evaluation for Rice method (IRRI 1996). All tested transgenic genotypes were tolerant to drought. Molecular characterization using southern hybridization showed that transgenic rice plants had 1-3 copies of transgen. Drought stress inhibited plant growth, which lowers the amount of seed and increasing the void content. 18.5.4 and 6.4.10 genotypes are considered tolerant to drouht. 18.5.4 genotype have the number of grains per panicle contents of 36 seeds and 6.4.10 genotype have a 38.03% percentage of empty seeds

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
