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   The study aims to determine the percentage of the population and attacks the larvae of Spodoptera spp. the planting scallion in District Modoinding. The study used survey method in planting scallion in District Modoinding, South Minahasa Regency is in the village Mokobang, Makaaruyen, Palelon and Kakenturan. Each location / Village determined three terraced planting scallion as sample sites. Sampling was done by slices diagonally and consists of five sub-plots. Observations made by observing the plant population of 20 clumps on each sub-plot. Larvae were found taken and collected in a bottle collection that already contains 70% alcohol, then calculated the amount. Sampling was carried out four times with intervals of once a week, namely the old plants 30 days after planting (dap), 37 dap, 44 dap and 51 dap. Observations made once the percentage of attacks that the old plants 51 days after planting. Each sub-plots randomly selected 20 family of plants as the plant sample to be observed. So the number of samples of plants were observed in each plot were 100 plants. Each family of plants counted the number of leaves, then observe and note the number of the diseased leaf. Criteria of pest attack is characterized by the presence of symptoms or attacks and the presence of larvae of Spodoptera spp. the leaves were observed Results of the study was a population of larvae of Spodoptera spp. The highest was found in the village of Mokobang reached an average of 88,31, then Makaaruyen 52,33, 51,48 Palelon village head and village Kakenturan 7,50. The observation of the population of Spodoptera spp. based on the age of the plant turned out to be the highest found in the plant was 51 dap which reached 67,37 then aged 44 dap 51,15, age 37 dap 43,75 and age 30 dap 37,56.

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 This study aims to determine the ef ect of beetroot ectract on the motality of Mas Keong (Pomacea caniculata L.) pests in Paddy Rice (Oryza sativa L.) which was carried out at the Green House of pests and Plant Diseases, Faculty of Agriculture Unsrat. The implementation time of this research was for three months from January 2020 to March 2020 and observations were made 1 day after application, 4 observations were made with a time interval of 6 hours. This study used a completely randomized design method with 5 treatments and 3 replications. Each replication consisted of 20 individual golden snails, so the total number of golden snails used was 300 individuals. The results of the research on the mortality observation of the mas snail pest showed that the mucus was released from the body of the golden snail so that the golden snail was poisoned due to the application of the extract of beetroot. Of the five treatments showed the percentage of snail pest mortality. The application of bitung fruit extract is Control = 0.00%, Extract Concentration 2% = 70.00%, Extract Concentration 4% = 80.00%, Extract Concentration 6% = 83.33% and Extract Concentration 8% = 100.00 %. <30 minutes the golden snail has stopped eating and its movements begin to slow down and burrow into the ground, over time its body will be released from its shell, this shows that the golden snail has died.
