DETERMINATION OF THE DIMENSIONS AND INDICATORS OF FOOD SECURITY IN INDONESIA: THE NATIONAL FOOD SECURITY BOARD-WORLD FOOD PROGRAM METHODOLOGY REVISITED Edmira Rivani
Widyariset Vol 15, No 1 (2012): Widyariset
Publisher : Pusbindiklat - LIPI

This study identifies the dimensions and indicators of food security and vulnerability that are relevant to bemonitored, and calculates a composite index based on food security and vulnerability indicators that represent thedimensions of food security based on the results of exploratory factor analysis. The method is as a new alternativeto the one used by the National Food Security Board (DKP)-World Food Program (WFP) in preparing the FoodSecurity and Vulnerability Atlas in Indonesia. The results show that the dimensions of food security are foodavailability, physical access, utilization, and social – economic aspects. The four dimensions explain 65,68%, ofthe total variance which indicates the models are fit. The indicators that should be included in the composite indexof food security are villages without access to road, female illiteracy, underweight children < 5 years, stuntingchildren < 5 years, household > 5 km from health facilities, and house hold without access to clean drinking water.This method may be considered as an alternative methodology in revising and updating the food security andvulnerability atlas that is regularly conducted by the DKP-WFP.

Publisher : Pusbindiklat - LIPI

The increasing number of industries and motor vehicles has an impact in the increased concentration of carbondioxide in the atmospheree. This has been causing green house effects (global warming). Therefore, the availability is essential for absorbing carbondioxide in large capacity, both in forest areas as well as in large cities. The objective of this research is to measure carbondioxide sink ability of fifteen (15) species of local plants and to determine the effective in absorbing carbondioxide. Leaf of local plants collection samples were collected from the Bogor Botanical Garden. Carbohydrate analysis was done in the Laboratory Biokimia BB-BIOGEN Bogor, while stomata examination was done in Laboratory Kayu Solid IPB. The data obtained were analyized using carbohydrate mole comparation and linear regression. The highest sink ability was found for canary (12,638.453 g/hour) and the lowest was found for sandalwood (1.379 g/hour). Sink ability of the other species ranged between 131.244 g/hour and 11,461.506 g/hour.

Publisher : Pusbindiklat - LIPI

Sunda strait has a relatively high seismic activity. The high seismic activity was caused by the seismic zoneat that region, including the faults zone. Based on the high seismic activity in the Sunda Strait, it is necessary to doresearch about the strain that occurred in the Sunda Strait region to determine the tectonic activity in that area andits seismic hazard. To observe the tectonic activity in the Sunda Strait, GPS observations were made periodicallywith static differential method at the observation points located in the Sunda Strait region. Based on the strainanalysis, the southwestern part of the Sunda Strait tend to experience compression and the northeastern part tendto experience extention. Sunda Strait had a relatively high seismic hazard with maximum PGA 0,47 g.

Waste is a national problem in Indonesia. This is related to the old paradigm of waste management which is only collected, transported, and disposed to the landfill. The same problem occured in Dusun Toisapu, Ambon. Since it’s establishment in 2003, Dusun Toisapu landfill used open dumping and it’s caused the increased negative externalities of environmental quality for the people who lives nearby. Ambon district officer has a new integratedwaste management in 2012 but the implementation is not going well because there was no sorting of waste (organic and anorganic) on source of waste. The governments finacial limitation causes the waste management services not running properly. Based on the results of research in Baguala and Nusaniwe, most people are willing to pay higher retribution for better services in Dusun Toisapu landfill with four scenarios. The highest average WTP in Baguala is Rp24.250,00/family/month for biogas scenario and the lowest is Rp20.804,00/family/month for incineration scenario. In Nusaniwe, it is obtained the highest average WTP is p21.228,00/family/month for composting scenario and the lowest is Rp18.220,00/family/month for sanitary landfill scenario. Value of WTP from people can cover operational costs for implementing four waste management scenarios that offered.

The research aimed to analyze: (1) the level of farmers behaviour on wet land conservations in Kulon Progo Regency; (2) the impact of land carrying capacity and non behavioural causes to farmers behaviour on wet land conservations; (3) the impact of farmers behaviour on wet land conservations of their agribusiness income. The method used in this study was descriptive analysis. The research was done in Kulon Progo Regency. The location chosen by purposive sampling method represented area that have high or low level of land carrying capacity. The respondents were chosen by multistage random sampling method. The analysis methods used in this research are proportion test by Dajan, multiple linear regression analysis, and simple linear regression analysis. The results indicated that more than 50% farmers in Kulon Progo Regency have a high level of conservations behaviour. The level of land carrying capacity did not influence farmers behaviour on wet land conservations. Non behavioural causes influenced the farmers behaviour on wet land conservations significantly were age, conservation knowledge, motivation, activity in group, non agribusiness income, availability of organics input and leadership. The high level of farmer’s behaviour on wet land conservations did not influence their agribusiness income.
