Abstract

Economic efficiency is often measured from production aspect and lack of attention to non-production aspect, such as transaction cost.

Abstract

The cost of termite Coptotermes curvignathus attack on buildings is enormous. In Indonesia, we know one environmental tolerant method to overcome the attack which is called baiting systems. However, this methods is relatively expensive, because there is only one product available all over the country. Chitosan is known for its bioactive ability as the retardant in mushrooms and fungi growth. Based on these facts, chitosan is assumed had the capability as a substance that could eradicate subterannean termite with baiting system which are environmental tolerant. Chitosan was dissolved in acetatic acid solvent. The concentration of the chitosan solvent used in this research were 0% (control), 0,25%, 0,5%, 1%, 2%, 3%, 4%, and 5%. The samples in this research were filter papers. The responses analyzed were percentage of termite mortality and weight loss percentages. Concentration of 0,5% chitosan gave significant affect on mortality of subterannean termite C. curvignathus. The highest percentage of mortality of subterannean termite C. curvignathus was by 4% concentration, which was 94,2%. While the weight loss percentage of filter papers gave a very significant affect at 1% concentration. The lowest weight loss percentage of filter papers was at 4% concentration of chitosan solvent, which was 7,4%.

Abstract

This research was aimed to obtain an optimum conditions for production of liquid fraction of crude palm (CPO) containing high concentration of  carotenoids,as well as to get  the optimum condition on production o carotenoids concentrate, by  using adsorption column chromatography method at laboratory scale. Adsorbent used  were rice hull ash and silica gel.  In order to get  high amount of carotenoids on liquid fraction of palm o the   palm oil was  treated with  n-hexane and   was  mixed by  using shaker.  Based  on  recovery and  tot carotenoids parameters contained in the  liquid fraction, the optimum condition to get high total carotenoids o liquid fraction was shown when employing 50% hexane,mixing at 200 rpm for 10 minutes,and decanting for days  at ambient temperatures. The  palm oil liquid fraction contained 275 ppm carotenoids with 81.0 recovery. The  next step   was the separation of  carotenoids from other components of palm oil by  usin adsorption column chromatography method with  rice hull ash  and  silica   gel  as  adsorbents. The optimu condition on  separation were found by  using ratio of rice hull ash:silica gel  30:10, which produced total corotenoids  of 317.2 11g   and   recovery  of   carotenoids  of   41.7%. The final  concentration in  carotenoi concentrate was 1865.9 ppm,4 times higher than the initial concentration in CPO. Key words: carotenoids,palm oil,adsorption column hromatography

Abstract

Germination of teak is often poor. The study on fruits and seeds germination of Java teak, Muna teak, and Malabar  Muna teak was conducted in a series of laboratory and greenhouse experiment. Teak fruits have saveral types of dormancy. So, fruits need pretreatment before they were planted. A recommended pretreatment of teak fruits is to soak the fruits during the night and dry them in the sun during the day.Keyword: teak, Tectoca grandis, fruit germination, seed germination

Abstract

Humpback grouper (Cromileptes altivelis) is sensitive to stress that coused low growth rate, mortality, and harvest. Iron is micronutrient that can enhance the immunity. This experiment was conducted to determine the iron supplement in the feed for humpback grouper fish to vitality increase at hypoxia stress condition. The fish weight 4.14+-0.01 g/ind. and was cultured in 60x40x50 cm aquarium and stocked at a density of 10 ind./aquarium. After reader for 61 days, the fish was

Abstract

Genes or regions on chromosome underlying a quantitative trait are called quantitative trait loci (QTL). Characterizing genes controlling quantitative trait on their position in chromosome and their effect on trait is through a process called QTL mapping. In estimating the QTL position and its effect, QTL mapping utilizes the association between QTL and DNA makers. However, many important traits are obtained in categorical scale, such as resistance from certain disease. From a theoritical point of view, QTL mapping method assuming continuous trait could not be applied to categorical trait. This research was facusing on the assessment of the performance of maximum likehood (ML) and regression (REG) approach employed in QTL mapping for binary trait by means of simulation study. The simulation study to evaluate the performance of ML and REG approach was conducted by taking into accounte several factors that may affecting the performance of both approaches. The factors are (1) maker density, (2) QTL effect, (3) sample size, and (4) shape of phenotypic distribution. Form simulation study, it was obtained that the two approaches showing comparable performance. Hence, QTL analysis could be performed using these two approaches due to their similar performance.

Abstract

Cancer disease are not detected only at adult but also at young age. One therapy for cancer diseases is chemotherapy and radiation, that give a side effect of infertility in the gonad, therefore, it is necessary to preserve the gonad. Sperm collection from adult is easy but not from the young patients.Keyword: transpalantation, testis, mencit muda, spermatogenesis

Abstract

Blood desease caused by blood disease bacterium is one of the important disease of banana in Indonesia. Disease control using resistant varieties was difficult to be practiced because the pathogen can attack all varieties of banana. Sanitation and eradication has been done by farmers but the desease still occured in the field with high incidence. Aplication of same rhizosphere bacteria failed to control the desease in the field.Keyword: Bacillus spp., Pseudomonas spp., endophytic bacteria, blood disease bacterium, banana
