Abstract

The research was conducted  in February-July 2010 in the greenhouse University Farm, Cikabayan, Dramaga, Bogor. This study aims to determine the effect of irrigation frequency on growth and production of five strains of  lowland rice, to determine critical point of soil water potential  for  drought tolerant screening.  This study used a randomized block  design  which consists of two factors and   three replications  for each combination of treatments. The results of this study indicate that the frequency of irrigation effect on plant height  at 8 and 12 weeks after planting (WAP), the number of tillering at  8 and 12 WAP, leaf length, ratio length / width of leaves, flowering age, number of productive tillers, panicle length, panicle number, number of grain per panicle, the percentage amount of grain fill, the weight of dry grain harvest, canopy dry weight, dry weight of milled grain, and the percentage decrease in production.  Drought stress decreased production by 32.44%,  41.52% and 48.87%  respectively at irrigation frequency of  8, 12, and 16 days. At optimum conditions of water availability, rice strains that produce the highest production is strain 1, 2, and 5. In drought conditions, all strains tested decreased production. Critical point of  soil water potential were -35.9, -25.8 and 0.3 kPa respectively on the vegetative phase,   reproductive phase, and   ripening phase.

Abstract

Twenty-nine soybean genotypes originating from various countries were evaluated on the tidal swamp of Indonesia to obtain information of agronomic character diversity as the soybean response to the environment and to obtain adaptive genotypes that can be used to develop soybean genotypes for the land. This study was conducted in a complete randomized block design with 3 replications. Diverse genetic backgrounds, countries and climatic regions of the 29 soybean genotypes were responsible for the difference in agronomic responses among the genotypes. All temperate and sub-tropical genotypes were able to produce seeds in the tropical type-B overflow tidal swamp. Adaptability based on seed yield resulted in 1 highly adaptive, 17 adaptive, 5 moderately adaptive and 6 non-adaptive genotypes. Adaptive and highly adaptive genotypes produced 1.56 - 2.58 tons ha-1 of seeds. Karasumame (Naihou), a subtropical genotype, produced the highest seed yield which was 65% higher than Indonesia average soybean productivity and 225% higher than soybean productivity with non-saturated soil culture technology on the tidal swamp. This study concluded that temperate and subtropical genotypes could be used as germplasm sources for soybean development in the tropical type-B overflow tidal swamp in Indonesia.

Abstract

Abstract Poverty alleviation programs in Indonesia are the same and uniform in all regions. Of course this ignores the characteristics and causes of poverty that vary in each region. The uniformity of poverty alleviation programs affects the slow pace of decline in the poor population. Spatial influence on poverty can be identified by spatial autocorrelation; there is a relationship of poverty in one region with other regions that are closed together. This study was aimed to analyzing poverty spatial distribution in all regencies/cities in Indonesia; analyzing the spatial distribution patterns of poverty in all regencies/cities in Indonesia; and knowing local spatial autocorrelation of poverty in all regencies/cities in Indonesia. The research methods used are Moran Index analysis, Moran’s scatterplot analysis, and Local Indicators of Spatial Autocorrelation (LISA) analysis. The analysis results show that the highest average of poor population percentage was in Papua and the lowest one was in Kalimantan. The results of analysis of Moran Index showed that the spatial distribution pattern of poverty in regencies/cities in Indonesia was clustered, it was called by poverty pocket. Pockets of poverty that occured do not correspond to government administrative boundaries, therefore poverty alleviation needs an integrative approach. In addition, this study also results that not all regencies/cities have significant spatial autocorrelation. This means that not all poverty conditions in a regencies/cities have a relationship with other regencies/cities. The fact that there are heterogeneity of poverty characteristics like this shows that poverty alleviation programs must vary in each regency/city.

Abstract

Cintalaksana Village is a village located in Tegalwaru District, Karawang Regency, West Java Province. This village has a land condition that fluctuates (terraces) and the average high rainfall is 2,600 mm-4,500 mm per year. This makes it possible to develop the agriculture, livestock and tourism sectors. The Sustainable Family Yard Program (PKL) aims at the residents of Cintalaksana Village to be able to utilize their home yards by planting TOGA, ornamental plants, fruit plants, and vegetable crops as well as the residents' houses which are used as a pilot to provide benefits to surrounding residents. The Sustainable Family Home Program (PKL) begins with licensing for village officials to carry out activities that involve residents and use vacant land owned by the head of RT 01, the village head, and the Lotus Posyandu 1. After the permit is completed, continue to clean up the empty land that has been overgrown with weeds using weeds using hoe. After that the making of beds in the land to sow kale and spinach seeds. For seedbed chillies use a polybag filled with a mixture of soil planting media and manure. After all the seeds are sown, watering is done until the soil becomes moist. Making verticulture using old bottles which are then planted with Alternanthera brasiliana and Portulaca ornamental plants. The implementation of the Sustainable Family Home Program (PKL) program in Cintalaksana Village went well. Residents began to realize the importance of utilizing vacant land around the house to become a sustainable yard. The yard can be planted with various types of plants so that it can meet food needs as well as the family economy. Keywords: Cintalaksana Village, family medicinal plants, yards
