Abstract

Spatial planning must perform protection on socioeconomic and ecological functions of space, and prevent negative impacts of space utilization on the environment. Constraints on such spatial planning increase continuously. In the Jadebotabek Region 2003 to 2006, flood-risky households increased with annual rate more than four times economic growth. This research aimed to determine strategic spatial planning instruments to control flood risks, by using Spatial Durbin Modeling approach. The model specifies explanatory variables into local and external. Local variables give effects as in a conventional regression model, while external variables give effects in a given pattern represented by a spatial contiguity matrix. Principal Components Analysis was employed to reduce multicollinearities among variables. Test and parameter estimation of the model were employed by using Forward Stepwise General Regression Model with ANOVA-Iike design and Sigma-Restricted Parametrization. Research area was Jadebotabek Region year 2003 excluding Kepulauan Seribu, constituted 12 districts and sevent watersheds. Measurement units were administrative regions at village level (1.488 units). The model fit to the data very significantly (R2=0.84; p

Abstract

Recently, Indonesia has big problem caused by dengue haemorraghic fever with A. aegypti as vector. Potential medicine and vaccine for curing this disease have not been found. The effective method to prevent this disease is the use of A. aegypti larvicidal. The chemical larvicidal has disadvantage for evironmental aspect. To solve this problem, the biological larvicidal has a good chance to develop. Indonesia has megadiversity which can be developed as biological larvicidal. Crude aqueous extracts and ethanol extracts of Jatropha curcas (Jarak pagar) seed and oil of Jatropha curcas were evaluated for larvicidal potential against the Aedes aegypti mosquito. Among all extracts, Jatropha curcas oil possessed a highest activity against the 3th instar larvae of Aedes. LC50 values of Jatropha curcas oil was 1507 ppm for 24 h and 866 ppm for 48 h. It was suggested that the Croton tiglium oil and Jatropha curcas oil possess larvicidal properties that could be developed and used as biological larvicidal. Keywords: Jatropha curcas, oil, Aedes aegypti, biological larvicidal, dengue  haemorraghic fever.

Abstract

For producing oil remains that remained at old oil wells (mature field), a method of advanced oilacquirement improvement known as an Enhanced Oil Recovery (EOR) should be applied. Surfactant plays animportant role in EOR process by reducing interfacial tension (1FT), altering wettability, reducing oil viscosity,and stabilizing dispersion to facilitate the process of oil jetting from reservoir to production well. To optimallycleanse oil that still remained a surfactant compatible with formation water and reservoir is needed. This studywas conducted to get the best time of sulfonation process for producing MES surfactant with lower interfacialtension for EOR application. Results showed that the best times of sulfonation process with lower interfacialtension value were 3 and 4 hours.Keywords: Surfactant, MES, sulfonation time, interfacial tension, EOR.

Abstract

The need of cement industry mine material to support the requirements on agricultural land resource as livelihood is two different interest that have a potential to emerge conflict of interest on nature resource utilization. Knowing the nature and human resource potentials as well as determining the direction of utilization planning strategy for sustainable land management. Research was carried out from November 2008 - April 2009. This is a descriptive qualitative study to describe the field condition. For determining sustainable land utilizationand management priority was used AHP by pair elements comparison method. General condition explained that land utilization for ecologically agriculture commodities is on appropriate land: un-suitability (NS), marginally suitability (S-3t, and S-3gt) for seasonal plants, as well as un-suitability (NS), marginally suitability (S-3te), and moderatly suitability (S-2te) for annual plants. The agricultural, industrial, and husbandry commodities that have proper economic potential is cassava, long bean, cucumber, mangoes, wood (albasia), tapioca industry, and goats husbandry. Main job as farmers is 85 %, 83°/o dont have an own land so they need an agricultural land. It is very important for their who have livelihood as a paisant, 72°/o moreover for theirs who were in a productive age. Result of AHPto determine the direction of land utilization and management pre, post, and non mining land showed that the stakeholders group who have important role on all land condition is the corporate. Priority ecology aspect on pre and post mining, socially aspect is on non-mining land utilization and management, the main choice for non-mining land utilization and management is food plants. Although value priority of bio-fuel plantation is higher than value priority of food plants, but food plants have more useful in social and economic. Priority pre-mining land utilization and management is food plants, and post-mining is land management based on sustainable environmentKeywords: land, management, mining, sustainable.

Abstract

Total income in Sumberjaya sub-district, West Lampung District, Lampung Province is affected by land usesystem composition. Amount of 150 respondents in three villages Tribudi Sukur, Sukajaya and Simpangsari hadbeen interviewed to get the information of household income. Simulation based on land use change scenarios(scenario 1: 13°/o monoculture coffee; scenario 2: 61°/o multistrata coffee; scenario 3: 23°/o forest; scenario4: 30% forest and scenario 5: 84% forest) were done to predict total community income in different typecomposition. Highest total community income occurred when 61 °/o of total area covered by agroforestry base oncoffee, but the lowest income occurred when 84°/o of area covered by forest. Converting 4°/o of existing shruband 9°/o of monoculture coffee to agroforestry base on coffee will increase 12.1°/o total income. In opposite,reforestation all Sumberjaya sub-district areas, except paddy field, horticulture land and settlement willdecrease 92°/o of total income.Keywords: Coffee, community income, scenario.

Abstract

Replacement of non-fragrant-native badh2 gene with mutated badh2 of fragrant rice is an alternative to engineer new fragrant rice varieties with good agronomic traits as those of non-fragrant. Fragrant gene (mutated badh2) of Mentik wangi donor was introgressed into non-fragrant Ciherang host through site-directed crossing. Mentik Wangi was crossed with Ciherang, and the progeny was further backcross until BC3F1. Bradbury marka-assisted PCR was used to select progeny in every cross and backcross generation. Ciherang, Mentik Wangi, and their cross/backcross showed different PCR profiles. The statues of badh2 gene (native/mutated), as well as alleles (homozygote/heterozygote) between samples were identified. Mutated badh2-introgression was also observed within the selected heterozygote cross or backcross progenies (Fl, BCl, BC2, and BC3), indicated successful transfer of mutated badh2 gene from donor to host. Keywords: Backcross, Bradbury, fragrant, Mentik Wangi, badh2, site-directed crossing.
