Abstract

South Jakarta is one of region in the DKI Jakarta facing an enormous growth in all aspects of development. The increasing of development activities and regional cause increase land uses dynamic. Fixed land supply compare with the increasing demand causing land use change particularly greenery open  space in South Jakarta. This research aims are: (1) to identify changing of greenery open space of South Jakarta, and (2) to find out population, infrastructure, anddevelopment growth rate of South Jakarta; and (3) to identify factors influencing change of greenery open space and relationship among the factors. The result shows that greenery open space in the period of 2002-2007 decreased about 362,21 hectare from 1299,22 hectares in 2002 to 937,01 hectares in 2007. In the same period number  of population and population density increased 0,7% per year while immigrants declined -23% per year. The region of South Jakarta in 2003 showed hierarchy III village was dominant (43 villages), while number of hierarchy II and I village, were 17villages and 5 villages, respectively. In 2006 number of villages categorized on hierarchy II showed increasing to be 19 villages while hierarchy III decreasing tobe 41 villages and hierarchy I was constant in number. Regional development could be due to growth on infrastructure development such as educational facility, health facility, and commercial area. The number of educational, health, and commercial facilities grew during the period of 2003-2006 with rate of 4,8%, 7,1%, and 20% per year, respectively. Regression analysis was utilized to identify factors influencing greenery open space area change. According to the result, land allocated for greenery open space in Jakarta?s spatial plan (RTRW) being the major factor affecting the change. The other factors were growth of health facilities, immigrants, population density, and educational facilities.

Abstract

Analysis of Regulation and Policy on Biosafety andLikelihood of Transgenic Seeds Adoption in Indonesia.Edwin S. Saragih, Santun R.P. Sitorus, Harianto, andSugiono Moeljopawiro. Since more than 10 years, anumber of works in field of modern biotechnology havebeen programmed in public research institutes anduniversities in Indonesia and few foreign companies haveput efforts in introducing transgenic varieties. This significantdevelopment raises intriguing question as to why there hasnot been any transgenic food crop seed planted by farmersin the country. A status quo was observed in whichregulatory regime on biosafety has been in a situation ofprolonged transitional phase and necessary institutionalframework has not been firmly in place. There weredistinguished lines among stakeholders on benefitawareness, risks perception and worry on multinationalcompanies’ control over seed supply. There is a fairexpectation that similar benefits experienced by adoptingcountries could also help increase food production inIndonesia. However, potential contribution of transgenicseeds for the country is still largely unexplored. There arenumbers of potential transgenic seeds namely transgenicrice, soybean, potato, tomato and corn, with the latter wouldshow slightly better likelihood of success once adoptionhappens. Decision making instrument as determinant factorin ensuring safe application and release of transgenic seedshas not yet existed despite the fact that capacity for biosafetyassessment conduct is undoubtedly sufficient. It is importantto note that the new regulation on biosafety (PP No. 21/2005)open opportunities for assessing transgenic product under atransitional clause. Nonetheless, the new regulation has notbeen able securing food safety statement of importedtransgenic products (especially corn and soybean) whichhave been used for domestic consumption.

Abstract

The high increase of population in the cities has an implication on the higher needs of city infrastructure, however, in order to create availability of sustainable infrastructure is not easy. The city needs measurement tools to identify its ability in building sustainable infrastructure. The purpose of the writing of this paper is: (1) to formulate the criteria and indicators of city’s sustainable infrastructure development; (2) to assess the level or status of the city’s sustainable infrastructure; and (3) to identify influential factors in the development of city’s sustainable infrastructure. The criteria and indicators of sustainable infrastructure gained from literature studies and expert consultation through Focus Group Discussion (FGD) are 5 criteria and 47 indicators. Indicators for environment criteria cover the efficiency in the usage of resources and the minimization of wastes. Indicators for social criteria emphasize on the easiness in gaining basic services, security, comfort and the community participation. Indicators for economic criteria focus on the increase of society’s welfare and local economy development. Indicators for technology relate with the level of availabilty and infrastructure services. Indicators for good govermance criteria cover leadership, organizational capacity, infrastructure planning an law enforcement. The Multi-Dimensional Scalling (MDS) with Rapid Appraisal of Infrastructure (Rapinfra) analysis show that the sustainability status of Bandarlampung infrastructure is less sustainable with the score of 38,05%. Influential indicators are gained from leverage factor analysis result towards the score of sustainability index for 26 indicators, which consists of : 4 indicators for enviroment criteria, 6 indicator for social criteria, 3 indicators for economy criteria, 8 indicators for technology criteria and 5 indicators for good govermance.
