Penggunaan Intranet dalam Proses Komunikasi Internal dan Implikasinya Bagi Organisasi Studi Kasus Penggunaan Intranet dalam Proses Komunikasi Internal dan Implikasinya Bagi Organisasi di Kementrian Perindustrian

This research departed from the phenomenon of the existence of the increase in the use of based communication technology the internet in this case the intranet in the organization of the public since almost for the last two decades. Nevertheless the study concerning the use of the intranet in the organization of the public often did not yet receive attention. This research will use the case study with the aim of getting the background that detail, intensive and deep concerning the use of the intranet in the process of internal communication and his implications in an organization. Moreover other consideration was the case of the use of information technology in this case the intranet in the organization of the public was the unique and interesting phenomenon because the organization of the public that in his management used the complicated bureaucracy system, was stratified, the complex was after wards pointed in a context of the environment that forced him to have to use communication technology as means of pushing the organization of the public became agiler. With this contradiction, the study concerning the use of the intranet and his implications towards the organization became interesting to be researched. The benefit of the intranet in the Ministry of the Industry began to aim this organization to the organization that more flexible and was open. Nevertheless the form of the bureaucratic organization continued to become the main part that adhered in the organization of the public. As the internal communication medium in the Ministry of the Industry, the intranet create the communication medium of one direction and two directions. The presence of the intranet brought a new practice in the Ministry of the Industry and without being released the intranet had implications in the practices of sharing knowledge that enabled an official to more understand of media knowledge and opened the concept thought as well as the capacity to know the problem of the organization. With the increase in knowledge then will increase also by competence of an official who will create satisfaction and active participation the official in overcoming various problems and the organization challenge. This condition will support the growth of empowerment of the official

Seasonal distribution of anti-malarial drug resistance alleles on the island of Sumba, Indonesia.

BACKGROUND: Drug resistant malaria poses an increasing public health problem in Indonesia, especially eastern Indonesia, where malaria is highly endemic. Widespread chloroquine (CQ) resistance and increasing sulphadoxine-pyrimethamine (SP) resistance prompted Indonesia to adopt artemisinin-based combination therapy (ACT) as first-line therapy in 2004. To help develop a suitable malaria control programme in the district of West Sumba, the seasonal distribution of alleles known to be associated with resistance to CQ and SP among Plasmodium falciparum isolates from the region was investigated. METHODS: Plasmodium falciparum isolates were collected during malariometric surveys in the wet and dry seasons in 2007 using two-stage cluster sampling. Analysis of pfcrt, pfmdr1, pfmdr1 gene copy number, dhfr, and dhps genes were done using protocols described previously. RESULTS AND DISCUSSION: The 76T allele of the pfcrt gene is nearing fixation in this population. Pfmdr1 mutant alleles occurred in 72.8% and 53.3%, predominantly as 1042D and 86Y alleles that are mutually exclusive. The prevalence of amplified pfmdr1 was found 41.9% and 42.8% of isolates in the wet and dry seasons, respectively. The frequency of dhfr mutant alleles was much lower, either as a single 108N mutation or paired with 59R. The 437G allele was the only mutant dhps allele detected and it was only found during dry season. CONCLUSION: The findings demonstrate a slighly higher distribution of drug-resistant alleles during the wet season and support the policy of replacing CQ with ACT in this area, but suggest that SP might still be effective either alone or in combination with other anti-malarials
