Abstract

Banana is commonly propagated vegetatively by suckers since most of edible banana are triploid, male sterile and parthenocarpic, use of conventional breeding for banana improvement is difficult.  Mutation induction and in vitro technique are alternative tools for banana improvement. The objectives of this research were (1) to determine radiosensitivity of banana cv. Ampyang against gamma irradiation, and  (2) to evaluate performance of plantlets regenerated from gamma irradiated explants of banana cv. Ampyang.  Explants of in vitro grown shoots were exposed to gamma irradiation at 0, 20, 25, 30, 35, 40, 45, and 50 Gy to determine their radiosensitivity. Growth and development of regenerated plantlets were recorded after 10 months of proliferation and regeneration periods. The CurveExpert ver. 1.4 analysis results indicated that lethal doses of irradiation reducing 20% to 50% of shoot growth (LD20-50) were 51.07 - 64.54 Gy.  All regenerated plantlets from irradiated explants produced less numbers of roots, and some of regenerated plantlets, showed significantly less plantlet fresh weight and height than the control one. Plantlets regenerated from explants irradiated with 25, 40, 50 Gy have longer leaves than the control. The regenerated plantlets from gamma irradiation treatments were successfully transferred into soil and they would be used to evaluate existence of variants among regenerated banana plantlets.   Keywords: induced mutation, gamma irradiation, lethal dose (LD20-50)

Abstract

An experiment to evaluate the growth and yield of two sweetpotato clones in intercropping with maize was conducted in IPB experimental farm in Sawah Baru from December 2004 to April 2005. In intercropping, the two sweetpotato clones of CIP-1 and CIP-6 were planted among to maize rows.  Planting space of sweet potato was 100 cm x 25 cm and maize was 100 cm x 12.5 cm in a plot size of 3 m x 3 m. Besides, the two crops were also planted in monoculture. The experiment was designed as a Randomized Block Design (RBD) and replicated three times. Dry matter of stem, leaves, and roots of the two sweet potato clones in intercropping were lower than in monoculture.  The same response occurred for yield of storage root.  The storage root weight of sweet potato clone, respectively, in monoculture and intercropping was 1.350 and 2.533 kg plot-1 of CIP-1 and 3.167 and 11.083 kg plot-1 of CIP-6.  On the other hand, there was no significance difference in growth and yield of maize in monoculture (3.35 kg plot-1) and intercropping (3.13 kg plot-1).  Land equivalent ratio of the intercropping maize with CIP-1 and CIP-6 were 1.7 and 1.4, respectively.  It means that land productivity can be increased by those intercropping.   Key words: Sweet potato clones, intercropping, maize

Abstract

The experiment was aimed at identifying QTL (quantitative trait loci) controlling ten traits of yield, yield component and plant morphology of rice based on BC1F1 of IR75862-206-2-8-3-B-B-B//IR64 mapping population consisted of 115 plants.  It was arranged in Completely Randomized Design with three replicates.  Ninety three SSR markers spread across the twelve rice chromosomes were used to map the QTL.  These markers were mostly segregated according to Mendel Law except for fourteen markers.  There were eleven QTL detected in eight traits, i.e., heading date, flag leaf length, plant height, panicle length, panicle weight, seed set, weight of 100 grains, and grain weight per plant, meaning that one or two QTL were detected in each trait.  These QTL were located at chromosome 2, 3, 4, 6, 11, and 12.  Some QTL were located at the same chromosome even at the same location indicating the close association of the traits.  It also indicated that there were common QTL which were found across genetic background and specific QTL which were found at specific genetic background.  Further study was prospective for the molecular marker application in rice improvement.   Key words: QTL, agronomic traits, SSR, rice

Abstract

Availability of moleculer marker to identify the important agronomic character of plant is needed to accelerate selection activity of plant. Particularly for the complex quantitatively inherited traits - like e.g. shading tolerance of soybean - the use of such a technique will speed up the process to produce adapted genotypes.The objective of this research is to identify the linkage of molecular marker RAPD with character of shading tolerance. The morphological specific characters wich is corelated to shade tolerance is the number of productive branchs. The intensity 75% of artificial shading is optimal level for doing selection of soybean genotypes. The inheritance of shading tolerance of soybean was controlled by gene with full dominant or by two genes pairs with dominant and ressesive epistasis. There was no maternal effect in the inheritance to shade tolerance. Heritability value (0.45 – 0.54) indicated that the proportion variation caused by the genetic factors was moderate. Molecular analysis by using RAPD technique showed that UBC153, ROTH 480.01, and ROTH 480.03 primer have polymorphic band that can be used for inheritance study and linkage analysis. All polymorphisms segregated independently of each ather. Interval mapping with Mapmaker/QTL indicated that the location of the three QTLs on linkage group were at marker tolerance locus of Roth 480.01-8125 , Roth 480.03-1125, and UBC 153-19125 .

Abstract

Natural disaster mitigation frequently focuses on the stage of emergency response, while the impacts of the disaster are often ignored. Community empowerment in the normalization of post-disaster physical problems becomes vital to optimally maintain victims’ health. The research aims to test the effectiveness of training village clusters with the competencies for disaster volunteers in normalizing post-natural disaster physical problems, using the quasi-experimental pre-post-test with control group design. Two natural disaster prone areas were selected from two different provinces, namely West Java and Banten. Sample was taken purposively, resulting in 23 people for each group. The findings show an increase in the dimensions of knowledge and attitudes of the village clusters in the normalization of post-natural disaster physical problems (p value 0.000). For the dimension of skills competency, there was a significant difference between the intervention and control groups at the end of the second month, including the ability to measure body temperature (p 0.000), calculate pulse rate (p 0.000), measure breath rate (p 0.036), measure blood pressure (p 0.000), provide basic life support (p 0.000), give wound care (p 0.000), splint a fracture (p 0.000), and use walking aids (p 0.000). The research recommends the importance of the formation and training of village clusters as a form of village community empowerment in disaster prone areas in the normalization of disaster victims’ physical problems.

Abstract

USB atau Universal Serial Bus merupakan perangkat komunikasi yang menyediakan bandwidth pengiriman data yang besar dan kecepatan pengiriman data mencapai 480 Mbps. Kecepatan pengiriman data pada USB terdiri dari Low-Speed (1,5 Mbps), Full-Speed (12 Mbps) dan High-Speed (480 Mbps).USB dapat menghubungkan berbagai jenis hubungan, dari sistem analog sampai sistem digital. Aplikasi yang menggunakan USB bermacam – macam, salah satu contohnya adalah Flash Disk. Dengan adanya flash disk ini, user semakin dipermudah dan dimanjakan dengan kapasitas data yang lebih besar dibangdingkan penyimpanan data konvensional (disket), dan dapat langsung dihubungkan melalui komputer (plug and play). Selain itu dengan desain ukuran yang kecil, flash disk dapat dibawa kemana – mana (mobile device). Jadi jika user ingin menyimpan, mengambil dan menyalin data baik itu dari komputer maupun antar flash disk dapat dilakukan dengan mudah. Akan tetapi, jika user ingin menyimpan, mengambil dan menyalin data antar flash disk, dibutuhkan perangkat host untuk mengatur dan mengontrol perpindahan data antar flash disk, perangkat ini tidak lain adalah komputer. Jika tidak ada komputer maka proses perpindahan data antar flash disk tidak akan terjadi.Pada penelitian ini direalisasikan dan dirancang perangkat yang digunakan untuk pertukaran data atau menyalin data antar slave (flash disk) menggunakan komunikasi USB tanpa bantuan komputer. Standar spesifikasi USB yang digunakan pada perangkat ini adalah USB 1.0 atau 1.1 dengan kecepatan pengiriman data sebesar 1,5 Mbps atau 12 Mbps.
