Abstract

ABSTRACTSoil Actinomycetes Population, Enzymes Activity, and its Relation with Carbon and NitrogenContent, in Bukit Bangkirai, East Kalimantan. Bukit Bangkirai is one of the tropical forest inIndonesia have been exposed with intense forest fire. The affected forest is subjectivelydivided into three level of damages, heavily damage forest (HD), low damage forest (LD) andcontrol (K). The objective of this research was to observe the abundance of Actinomyceteswhich have important role in ecological process. Through decompotition of organic materialsand nutriens cycle. Actinomycetes were isolated and enumerated by SDS-YE method. CFU/ gsoil (x 104) in K, HD and LD are 41,86 ± 25,52, 16,09 ± 5,70 and 18,96 ± 4,19 respectively. Amylaseand cellulase were determined by DNS method. Carbon and Nitrogen total were determinatedby CN analyzer. The different of amylase, cellulase activities and abundace of Actinomycetesbetween HD, LD, and Control plot were not significant. However, carbon and nitrogen totalare different. LD plot has the highest carbon and nitrogen total, followed by control and HDplot. There has no significant different among plot observed may indicate microbial communitiesof soil in Bukit Bangkirai have been recovered.Key words : actinomycetes, fire forest, amylase, cellulase, nitrogen total, carbon total

Abstract

ABSTRACTNipah Virus Seroepidemiology in Flying Fox and Pig Husbandry in Several Areasof Indonesia. Nipah is a dangerous zoonotic disease which was carried by flying fox.The disease had been occurred in Malaysia in 1999 and infect pigs and caused humandeath. Indonesia is adjacent country to Malaysia, hence, a serological study had beenconducted on 156 flying fox (P. vampyrus) sera from North Sumatera, West Java, CentralJava and East Java. Besides that, 2740 pig sera was randomly collected in differentprovinces to detect Nipah infection. Both flying fox and pig sera were tested usingELISA test to detect the presence of Nipah antibody. The results indicated that 37 from156 flying fox sera (23.7%) has antibodies against Nipah virus. Infections were occuredin all sampling sites with the prevalence varied from 18% to 33 %. Meanwhile, no pigsera tested (2740) had antibody against Nipah virus. Based on these results it can beconcluded that Nipah virus infections were occurred in flying fox in some parts inIndonesia, but not in pigs. It was suggested that the presence of Nipah virus in Indonesiashould be anticipated. Hence the distribution of its infection in pigs and human must beanticipated. Monitoring of Nipah infection in areas adjacent to Malaysia must be increasedto detect the entering of the disease in Indonesia.Keywords: Nipah, pigs, flying fox, serology

Abstract

ABSTRACTThe Parasitics wasp superfamily Chalcidoidea (Insecta : Hymenoptera) potentialas biological control agents for pests of Eggplant (Solanum melongena) and BitterMelon (Momordica charantia). The recent contribution on diversity of parasitics waspChalcidoidea for biological control perspective against the pests of the two economiccrops was discussed, with emphasis on the most significant steps for the selection ofcandidate biological control agents. The survey was carried out in Bogor, West Javausing Malaise traps, Yellow pan traps and a Swept net. The crops are the most economicallyimportant in agriculture not only in West Java but also in Indonesia. Meanwhile the pestcontrol of those two crops has so far been used only by the insecticides and would affectto the health of the production of the crops when the vegetables are consumed freshly. Ofthe 78 species within 8 familes of Chalcidoidea are found in both crops, 7 species can beclassified as potential biological control agents. With the object of biological control ofthese 7 species, a survey was carried out to establish the presence and importance oftheir natural enemies on those crops in Java.Key words : Bitter Melon, Chalcidoidea, Eggplant, Parasitoids, Pest control.
