Abstract

Malathion thermal fogging has been used for control of Aedes aegypti, a Dengue Haemorrhagic Fever (DHF) vector since 1972. Inspite of this programme, DHF remains a major public health problem. In an effort to get alternative insecticides for Aedes aegypti, a trial was conducted with Lorsban 480 EC, Icon 25 EC and Malathion 96 EC, utilizing a thermal fog Machine SN II to evaluate the effectiveness of each insecticide. The trial was carried in Kebumen regency, Central Java Province during the months of October and November 1992. Fogging was conducted in 2 cycles with an interval of one week. The result showed that the thermal fogging applications of Lorsban 480 EC, Icon 25 EC and and Malathion 96 EC are able to reduce the indoor population densities of Aedes aegypti and Culex quinqueffasciatus for about 1 and 2 weeks respectively. The percentage number of positive ovitraps and the average number of Aedes aegypti indoors were reduced for about 2 and 5 weeks respectively by applying Malathion and both Lorsban 480 EC and Icon 25 EC.

Abstract

Penelitian ini bertujuan untuk mengkaji komunitas rayap akibat alih guna hutan dan hubungannya dengan faktor lingkungan. Penelitian dilaksanakan dari bulan Desember 2011 sampai Juni 2013. Dilaksanakan di wilayah Taman Nasional Lore Lindu di sekitar Desa Rahmat, Kecamatan Palolo, Kabupaten Sigi. Pengamatan rayap dilakukan dengan menggunakan metode transek. Parameter yang diamati adalah parameter lingkungan, iklim mikro, sifat fisik dan kimia tanah. Total diversitas rayap yang ditemukan adalah 20 spesies, yang terdiri dari 15 spesies pada hutan primer, 15 spesies pada hutan sekunder dan 8 spesies pada agroforestri. Biomassa pohon tertinggi pada hutan primer (620,91 Mg/ha), nekromas dan jumlah seresah tertinggi pada hutan sekunder yaitu masing-masing 8,22 Mg/ha dan 19 Mg/ha. Hasil penelitian ini membuktikan bahwa alih guna hutan menjadi agroforestri diikuti oleh perubahan komunitas rayap. Suhu tanah dan suhu udara meningkat setelah alih guna hutan.

Abstract

Gelam wood commonly use for house pole in peatswamp land of Central Kalimantan. However increasing the utilization of gelam wood lead to harvest a small diameter of trees. This research aims to study the percentage of heartwood, physical mechanical properties of gelam wood of different diameter class.Keyword: diameter class, gelam wood, heart wood, physical mechanical properties

Abstract

This study aims to assess the structure and communities of termite caused by changes in land use. The research was conducted from December 2011 to January 2013, Implemented in Lore Lindu National Park area around the village of grace Palolo Sub district, Sigi Regency. The observation of termites was conducted using transect method. Parameters observed were environmental parameters, soil physical and chemical characteristics. The total diversity of termite species found was 15. Diversity of trees, nekromas, and the amount of litter that is higher in secondary forest than in agroforestry cause soil water content and moisture become higher in secondary forests and there fore contributes toan increase in soil organic matter content. Key Words : Agroforestry, diversity of  termite, forest use change, secondary forest.
