Abstract

This study was aimed to utilize rice husk and corn cob and skin to produce biobricket as an alternative to kerosene and gas through examination of caloric value and ash content of the rice husk, corn cob, corn skin and biobricket combustion characteristics.  The study used an experimental method to reexamine the quality of biobricket in laboratory and field. The former started with  charcoal furnace preparation and rendement calculation of the rice husk and corn skin charcoal produced.  The charcoal quality test was examined through caloric and ash level valuation. The biobricket quality was based upon size variations, 15 mesh,  20 mesh,  25 mesh, 30 mesh and pressure through compression process using a hydrolic pump of  5000 kg/m2. The rice husk and corn skin was collected from North Minahasa Regency. Variables observed in the study were charcoaling process using a furnace covering rendement output (%). charcoaling duration (minute), maximum charcoal temperature (oC), and caloric value (cal/g) and ash content (%) of the charcoal tested in the laboratory of Research and Industrial Standardization Board, Manado. The biobricket quality characteristic obtained was boiling time.The highest water boiling time occurred in 15 mesh size in 27 minutes, maximum temperature under the pan, 383oC in 30 mesh, duration of 562 minutes of biobricket charcoal burnt out in 30 mesh and the best (least) ash combustion remain of the biobricket charcoal of 12.48% in treatment 15 mesh. The agricultural wastes, as rice husk and corn skin, could be produced as environmental friendly biobricket with the best treatment of 15 mesh size that resulted in the highest boiling duration and the least ash residue, and the treatment of 30 mesh size gave maximum temperature under the pan and the longest time of burnt out biobricket charcoal.

Abstract

ABSTRACT The objective of this research was to know the diversity of natural enemies (parasitoid and predator) on wet rice-field, so that could be bread to control pest insects with a tactic that is easy, cheap, efficiently and environment safe. Catching a natural enemies species was conducted in district of Tumpaan and Tenga (which was the centre of rice production in South Minahasa Regency) by sweeping (using insects trap) and direct observation in the field. The specimen insect was brought to the laboratory for identified. Diversity was measured using Shannon-wavers, and then continued to decide the species abundance average level. The natural enemies species which were found consist of five ordos of predator (Araneida, Hemiptera, Odonata, Coleoptera, and Orthoptera); 10 families; and 16 species; two ordos, 10 families and 13 species of parasitoid. The result of variance analysis showed that the abundance average level (J) of 29 species (predators and parasitoid) which were found almost the same and this value refer to value that almost the same on the diversity in species group (H) during observation either the old crop stadia or the location of rice plant.

Abstract

Hypsiphyla sp. include the Order Lepidoptera, Family Pyralidae. These insects is one of the important pests on mahogany plants (Swietenia macrophylla King.).  This pest has been found to attack S. macrophylla plants in North Sulawesi, especially in the area of mahogany plant centers namely North Minahasa Regency and Tomohon City. The aim of the study was to determine the CO1 gen profile of mahogany shoots borer (Hypsipyla sp.) on mahogany plant (Swietenia macrophylla) in Minahasa Regency and Tomohon City, North Sulawersi Province. The method used is descriptive method, consists of extraction or purification of total double strands DNA (dsDNA), amplification of CO1 gene by PCR method, visualization of PCR results with atomatic electrophoresis qiagen, and sequencing. The sequenced data that is the construction of the phylogeny tree are described according to clusters which give the morphometric character of each sample. The results of the analysis of genetic differences between Hypsipyla sp. origin of North Minahasa and Tomohon namely 3.8%–4.4%. Hypsipyla sp. origin of North Minahasa and Tomohon with H. grandella namely 9.0%–9.3%. Based on the results of this analysis it can be seen that the kinship of Hypsipyla sp. in North Minahasa Regency and Tomohon City it is closer to H. robusta than H. grandella. Results of cluster analysis of Hypsipyla sp. in North Minahasa Regency and Tomohon City, North Sulawesi Province compared to H. robusta and H. grandella in the Gen Bank mapped in the phylogeny tree construction indicate that Hypsipyla sp. in North Mihasa Regency and Tomohon City, North Sulawesi Province already exists or forms a separate clade with H. robusta and H. grandella clades in Bank Gen.
