Abstract: Makalah ini melaporkan suatu eksperimen penangkapan nyamuk menggunakan demountable cage di sebuah danau di Banyuwangi Jawa Timur. Dari eksperimen itu terbukti bahwa perangkap yang kecil ternyata lebih praktis digunakan diban-ding yang besar. Lebih mudah dibongkar-pasang dan dibawa-bawa. Di samping itu tangan lebih mudai: menjangkau ke segala penjuru untuk menangkap nyamuk-nyamuk. Metode penangkapan ini dapat digunakan sebagai teknik sampling dalam mengukur tindakan pe-ngendalian larva, dalam mempelajari dinamika populasi, dan memeriksa ada tidaknya perkembang-biakan nyamuk.

Inswiasri Inswiasri,Hendro Martono
Media of Health Research and Development , 2012,
Abstract: Kajian tentang pencemaran di wilayah tambang emas rakyat perlu dilakukan untuk mendapatkan gambaran sejauh mana kegiatan proses penambangan emas yang dilakukan oleh masyarakat berisiko mencemari lingkungan. Kajian dilakukan terhadap hasil penelitian di beberapa negara yaitu; Brazil, Equador, Peru Selatan, Nevada, California, Papua New Guinea, Ghana, Queenland Australia, Mongolia, Tanzania, Bolivia, Zimbabwe, Philipina, Lao PDR, Sudan, Afrika Selatan, Pilipina, Indonesia. Beberapa penelitian tentang tambang emas rakyat memfokuskan pada studi penggunaan bahan berbahaya logam Hg seperti, Hg yang terbuang ke lingkungan, kadar Hg dalam sumber air minum dan ikan. Dapat disimpulkan bahwa kegiatan tambang emas rakyat di berbagai wilayah mempunyai kesamaan yaitu menggunakan Hg untuk proses amalgamisasi. Akibat amalgamisasi tersebut, sering muncul pencemaran Hg di lingkungan pada saat amalgamisasi dan pemijaran sehingga mengkontaminasi sumber air minum dan ikan yang sangat diperlukan oleh masyarakat sekitar tambang. Oleh karena itu monitoring lingkungan sangat diperlukan sebagai peringatan dini bila terjadi pencemaran. Kajian tentang cost and benefit kegiatan tambang emas belum ada yang melakukan. Di masa mendatang kajian cost and benefit sangat diperlukan untuk dasar penyusunan kebijakan kegiatan lambang emas rakyat. Berdasarkan hasil penelitian tersebut, disarankan untuk menjaga pencemaran jangan sampai meluas, perlu ada sentralisasi (tata ruang) kegiatan proses pengolahan tambang rakyat. Penggunaan alat (retort-amalgam) dalam pemijaran emas perlu dilakukan agar dapat mengurangi pencemaran Hg. Penyuluhan kepada masyarakat tentang bahayanya Hg perlu dilakukan. Bagi tenaga kesehatan perlu ada pelatihan surveilans risiko kesehatan masyarakat akibat pencemaran Hg di wilayah tambang emas rakayat. Kata kunci: Tambang emas rakyat, pencemaran

Bulletin of Health Research , 2012,
Abstract: On the distance of 0 and 120 meters from main roads, it had been performed a survey to assess the quality of ambient air in Jakarta. Ambient air samples were collected from 21 sampling points with the distance of 0 meter and 120 meters from main roads respectively. The highest average content of N02 gas in ambient air both on 0 meter and 120 meters from the main road was in Central Jakarta. The highest difference ofN02 gas content between the two sampling points was in West Jakarta (28.27 %), and the lowest one was in North Jakarta (11.73 %). In whole areas of Jakarta, the average content of NO2 gas was 18.89 pg/cu.m (0 meter), and 15.44 pg/cu.m (120 meters), so the difference of the gas content between the two sampling points was 18.26 %. The difference of the NO2 gas content means between the two sampling sites was not significant. Controlling the gas pollution should be addressed to mobile and constant sources of the gas emission.
