The purpose of this study to determine the influences of student’s attitudes through physics subject and motivation as the results of physical study. This study used survey methods, namely to find a clear result of the problem. Instruments that used in this study was a questionnaire about student’s attitudes to physics, study motivation and results of physical study, each of them which amounted to 20 questions, 20 questions and results of physical study took from score at middle in a semester. The data obtained will be analyzed using path analysis. This study gives the following results: 1) Student’s attitudes to physics are not given directly to the results of physical study. This way looked from score coefficient correlation between X1 and Y is 0,116 and coefficient get effect (P31) is (-0,0378). Negative score was showed that means three is no positive effects and significant value between attitudes of students through physical subject Student’s attitude through physical subject with its score. In the other hand, students who have positive attitude with Physical subject at Technical Informatics program, as the result it is not give effect to the test score. 2) Learning motivation gives effects directly with result of study at students’ basic physic subject. It is showed by coefficient value of correlation between X2 and Y is 0,678 and coefficient get effect (P32) as 0,686. Positive value, it’s showed that means there is a positive effect and significant value between students learning motivation through result of study at basic physic subject. This positive result gives meaning that students who get high motivation so get high score also. This result have enough proved that learning motivation is so important and it’s really effected in learning process. 3) students’ attitude in physic gives effect negative indirectly through result of study at basic physic subject through learning motivation. This things is showed by coefficient value on correlation. It is showed by between X1 and Y is 0,116 and coefficient value get effect (P31) is -0,0378, also coefficient correlation between X1 and X2 is 0,224 and coefficient get effect (P21) is 0,224 so coefficient is not give effect directly between X1 to Y X2 through with multiple P31.P21 = (-0,0378)(0,224) = -0,008467. Seeing the negative signs from the result above, the value means that there is no significant positive effect directly between student’s attitude at basic physical subject through students’ learning motivation. This results gives information that student’s positive attitude from students at Technical Informatics students to basic physical subject will not give effect to their result of study through learning motivation. Keywords: student’s attitudes, motivation, physics, path analysis

Indonesia is the one of banana biodiversity center in the world. Genetic diversity of this plant is large. Thus, it is important to conserve these genetic resources to support banana breeding program. Collection of banana germplasm is more important due to over exploitation in the natural habitats in Indonesian forests without sufficient culture or replacement efforts. Studies on cytology and morphological characters of plants are required to avoid duplications of germplasm collections. This research would be explored 30 accession of Indonesian banana germplasms from East Borneo, Banjarmasin (South Borneo), field germplasms from Cibinong, Yogyakarta, Rembang, Purworejo, and Subang. There were 20 accession of germplasms collections that would succeed to collect in vitro. Chromosome analysis revealed different ploidies: diploid (2n=2x=22) and triploid (2n=3x=33). Related similarity in dendogram from ten accessions of banana (Rotan, Telunjuk, Emas, Hutan, Lampung, Api Merah, Api Hijau, Morosebo, Tanduk, and Barangan) based of vegetative and generative characters divided into four groups at 88.75% similarity; group I were accessions of Emas, Telunjuk, Rotan, and Hutan;accessions of Lampung and Morosebo were group II; group III was accession of Tanduk; and the last group were accessions of Api Merah, Api Hijau and Barangan. Result from in vitro experiment, induction of banana bud was depending of fenolic acid that results from specific variety, growth hormone concentration, and genome. Banana with A genome (diploid AA or triploid AAA) had the best growth because the result of fenolic acid was lower. Culture media with 5 ppm BAP was elevating in vitro bud of banana germplasm that have more number of A genome. The banana whose have more number of B genome was need higher concentration of BAP. Ambon Kuning whose have AAA genome had the higher multiplication of bud rather than Api Hijau and Api Merah whose have AAB genome or Kepok Kuning with ABB genome. Key words: genome, chromosome, Musa spp., ploidy, stomata

Economic crisis which knocked over Indonesia in 1998, nowadays have turned into crisis of multidimensional or multicrisis as its effect. In all of aspect, and natural environments even also its impact from effect of careless human being. Indonesia notorious have many natural resources but do not make balance with management effort up at benefit. In fact, this management can be done creatively by using methods of Biotechnology which in fact human being have done since ahead, but only unheard-off. The aim of this writing is to give global Biotechnology information which expected can be exploited creatively by society in managing Indonesia natural resources to our importance. Activity of Biotechnology include transgenic engineering that able to yield better and more product from source of which a little and less potential. For example like agriculture aspect, can increase the yield as well as by using methods of Biotechnology. Until in this time, agriculture have hundreds of gene from various carried over by a success source of crop and produce hundreds of variety type the new crop that called crop of transgenic. With technology of DNA recombinant, modified foreign gene of best variety can be injected to most of all life cells. Keywords: multicrisis, management effort, natural resources, Biotechnology, DNA recombinant
