Abstract

The agricultural sector, particularly the rice farming system (SUT) is very vulnerable to climate variability and change. SUT that rely heavily on water will be easily affected by climate variability and change when the water supply deficit of needs that should be. SUT is still dominant in the food supply in Indonesia, so the shock of farming due to extreme climate events will have a major impact on food security. Many findings indicate that the frequency and intensity of extreme climate events will increase as a result of global warming. Extreme climate events dominant occur in center of rice production in West Java like Indramayu is drought. Approximately 80°/o of the causes of the rice harvest failed in the district of Indramayu is the incidence of droughts. Farmers as the main actors receive large impacts due to drought is expected to be increasingly difficult to develop the farm. It is therefore necessary to have protection program for farmers from the impact of climate events such climate extrim. One option is starting a lot of feasibility is Climate Index Insurance. This study aimed to assess the feasibility of the implementation of the climate index insurance system in Indramayu. Analysis step is performed include (i) preparation of endemic drought maps are required as the basis in determining the priority areas of climate risk management and (ii) the determination of climate index value (threshold value) to be used as an index into the determination of the value of insurance claims. This study found that climate indices that can be used for the three villages at high risk of drought is high rainfall during the dry season. Index value for the three villages is 168 mm, 248 mm and 472 mm for Cikedung, lelea and Terisi. Potential applications of Climate Index Insurance for rice SUT in Indramayu is high because about 90°/o of the people are rice farmers. Besides benefit of rice farming is also quite large with B/C from 1.4 to 1.8 during the wet season and 1.2 to 1.7 on the dry season, so the expected ability to pay insurance premiums high enough.

Abstract

Year by year, globally the production of petroleum decreases but its demand increases. The world will get the energy crisis including Indonesia if that condition happens continously. Because of that, Indonesia starts to develop IOR (improved oil recovery) method for their oil fields.  IOR method is an improvement of the secondary phase in which the oil recovery is expected to increase oil production.  One method of IOR is chemical injection with surfactant for injection.  Surfactant is dissolved with injection water and injected to reservoir.  Generally, surfactant of petroleum sulphonates is used for oil recovery.  Due to the weaknesses of petroleum suphonates such as not resistant in high salinity and high hardness water, therefore it triggers to get surfactant substitute like MES (methyl ester sulphonates) that is synthesized by bio-oil from Jatropha curcas L.  The study was aimed to know the performance of MES surfactant formula from jatropha oil for IOR in fluid sample of oil field and synthetic sandstone core.  The best condition from this research was surfactant 0.2 PV with the soaking time of 12 hours. This formula gave the highest of  incremental total oil recovery 61%. The number were resulted from 48% waterflooding and 13% surfactant injection.

Abstract

Cement board is a composite wood product has advantages such as fire resistance, termite, water resistant, and has good sound insulation properties. Bamboo is suitable material that can be used as a raw material of cement board. The objectove of this study was to determine the physical-mechanical properties of wool cement boards from betung bamboo (Dendrocalamus asper) in various densities. Mechanical testing included nondestructive testing performed using the sound waves velocity method (stress wave velocity). The material used was particles of wool/ excelsior dimensions. The adhesive used was Portland cement type I by the ratio of bamboo: cement: water 1:2:1. Target board densities were 0.5 g/cm3; 0.8 g/cm3; and 1.0 g/cm3. The results showed the higher density of the board the higher mechanical properties of boards. The difference density cement board was more influential on mechanical properties (MOE, MOR, SW) board compared with those physical properties. Nondestrcutive testing using sound waves velocity method can be used to predict mechanical bending properties of wool cement board of betung bamboo as indicated by the close relationship between the parameter estimators (dynamic MOE) and static testing value (MOE and MOR).

Abstract

One effort to improve of high-quality of maize seed were the development and application of methods for genetic quality testing, such as SSR marker. Another effort was used of rhizobacteria for increased the availability of nutrients, especially P in the soil. The aim of this study were: 1) Microsatellite markers specific to male and female parents of maize hybrid; 2) Seed genetic purity by using molecular marker; 3) Rhizobacteria that could increase the physiological quality of maize hybrid seed; and 4) Rhizobacteria that could increase the growth of plant and efficiency of fertilizer P. The result showed that: 1) From five markers tested, three markers namely phi96100, phi328175 and phi072 produced polymorphic bands and capable to distinguish parental lines of two maize hybrids. Microsatellite marker phi96100 was specific used for testing genetic purity of cv.Bima-4 and phi072 for cv.Bima-3. While phi328175 was specific markers to both hybrids maize. The test of cv. Bima-3 and Bima-4 indicated that genetic purity of both varieties were 97.5% and 80% respectivelly; 2) Isolates B28 and B46 could increase IV 19% and 22% respectively, and had a high speed of growth compared controls; 3). Isolates B46, B42, B13, P14, P31, AB2, AB3, AB11, ATS4, and ATS5 could increased of germination compared to control; 4) Treatment of rhizobacteri significantly affects on plant height 2, 4 and 6 week after planting (WAP); 5) P fertilizer dosage were not significantly influenced on the number of leaves at 2 and 4 WAP, but significant at 6 WAP. Isolate of B28, B42 and ATS4 were potential for increased of plant growth.

Abstract

Melia azedarach is mostly found in community forests in West Java. One of the factors that affect forest productivity is high quality seed, but seed quality is not easily obtained by farmers. The general objective research is to provide good quality seeds of Mindi. Specific objectives are: 1) Determine the potential and the distribution of genetic resources of Mindi); 2) Determine the reproductive system; 3) ) improve  seed technology  to develop the seed viability of mindi, and 4) Build the collaborative management of mindi seed source by farmer. Seven  populations of mindi plantation in the community forests were chosen for this research. The study was conducted over three years (2009-2011). Biophysical condition such as  soil, light, temperature, altitude and humidity affect growth, flowering, fertilization and fruit production of mindi. The flowering cycle was proceeded for 6-7 months. The average value of reproductive success (KR) is 58%. The genetic variation of mindi in community forests in West Java was He = 0.1603-0.1956. The thickness of the seed coat, the high  content of lignin and ABA is create a difficulty in seed germination. Prospective populations to be developed for seed sources were proposed namely Sumedang, Wanayasa and Talegong.

Abstract

Vaccination is one of the chosen strategy for controling AI H5N1 in Indonesia. Vaccination able to induce protective antibodies against AI but unable to inhibit viral infection. Determination of antibody titers in the serum from bird vaccinated with AI-H5N1 vaccine consisting of 2 or 3 different AI virus isolates difficult to be meassured if the antigen for HI test is uncalibrated yet. Furthermore, the determination of a minimum protective antibody titer against the challenge of AI virus circulating in the field at this time needs to be done.  This study aims to determine the H5N1 AI virus antigen for standart HI test and the minimum titre of antibodies that able neutralize virus infection. As much as 55 chickens were divided into 11 groups, 10 groups vaccinated with commercial AI vaccine and AI H5N1 field isolat antigen. Four types of commercial vaccines were veccinated to one group and seven other groups vaccinated with the antigen AI Legok 2004, Nagrak Ag 2009, Ag Lawang 2010, as well as polyvalent Ag combination of these three types of antigen. After third vaccinations, the presence of antibodieswere meassured by HI test. Serum with a titer test 26-28 were tested for the capability of virus neutralizationin using virus neutralization test against three different H5N1 AI virus field isolates. The test results showed that the H5N1 subtype AI virus antigen representative as standart antigen for HI test is antigen Legok 2004 and the minimum titer which able neutralize H5N1 AI virus field isolates 28.

Abstract

One form of sustainable wildlife utilization with ecological and economic values is game hunting. Due to game hunting’s promising prospects, Perum Perhutani planned to develop their deer captive breeding area (PRJ) into a hunting garden. The objective of this research was to study the prospects of deer captive breeding area of Perum Perhutani BKPH Jonggol, West Java into a hunting garden based on ecological considerations. The research was conducted in 2006. Based on direct observation, interviews with the locals and local officers, and observation of land cover change due to increase in population, it was concluded that Block 9 was the most ideal site for hunting garden due to its varied slopes which was preferred by deers, ideal land coverages such as grassland, shrubs and plantation forest, lack of enclave, abundant grazing area and accessible by the hunters. Based on land topography and land coverage, the most suitable hunting method for Block 9 was stalking. According to the Directorate General of PHPA (1988), the only weapon allowed for game hunting is firearm. Based on calculations and literature reviews, the maximum number of hunters allowed in Block 9 is 108 hunters per year with a hunting season of two months, during July and October. Assuming 100% hunting success with maximum number of hunters allowed, the hunting quota would be 108 deer per year. Further studies are required to determine the number of initial population to be introduced to the hunting area and time to start hunting activities, as well as prospects of PRJ development as hunting garden based on socio-economic considerations.
