Abstract

ABSTRACT  The purpose of this study was (1) to know the growth and production of local waxy corn on various dosage of NPK fertilizer ; (2) to obtain the proper dosage of fertilizer in growth and production of local waxy corn. This study was conducted in Insil village, Passi Timur District, Bolaang Mongondow Regency with attitude 1100 meters above sea lever, from June to August 2016. Using a Randomized Block Design with five treatments of NPK fertilizer dosage which are P0 = 0 kg ha-1 of NPK fertilizer  (as a control), P1 = 200 kg ha-1 of NPK fertilizer, P2 = 300 kg ha-1 of NPK fertilizer, P3 = 400 kg ha-1 of NPK fertilizer, and P4 = 500 kg ha-1 of NPK fertilizer. The results showed that treatmen of NPK fertilizer dosage only had effected on plant height of local waxy corn but had no effected on length of cob, diameter of cob, fresh weight of with corn husk and fresh weight of cob without cornhusk.

Abstract

ABSTRACTThe purpose of this research is to identify the composition of traditional market waste, todetermine the effectiveness of composting and to determine the mutrient content of the compostingtechnology of Accelerated Revolver Windrow Composting. Conducted in the city of Manado withdescriptive qualitative research methods where data analysis is devided into 3 namely indentificationof composition, composting effectiveness and compost content analysis. The result showed that : (1)identification of Pasar Bahu waste consisted of 84.21% organic waste from vegetables and 15.79%inorganic waste, Pasar Bersehati waste 91.67% organic waste from vegetables and 8.33% inorganicwaste; garbage Pasar Karombasan 89.72% organic waste from vegetables and 10.28% inorganicwaste; (2) The effectiveness of composting using mature compost parameters shows that composproduced has an average level of composting effectiveness of 90%; (3) The content of compostproduced by Accelerated Revolver Windrow Composting technology made from organic marketwaste and beef cattle feces after being compared with the nutrient content criteria can be categorizedwell and the value of the content is in accordance with the quality standars of organic fertilizer bySNI.Keywords: Compost, market waste, city of Manado, ARWC

Abstract

ABSTRACTGolden snail (Pomacea canikulata L.) or also known as mulberry snail is one of the main pestsof rice plants in North Sulawesi, including in the City of Tomohon. This golden snail pest likesyoung rice plants with the intensity of damage varies from 10-100% depending on the level ofpopulation on each land. This pest destroys plants by grating plant tissue and eating it. In responseto help the problems faced by farmers, research has been carried out on the population of thegolden snail pest (Pomaceacaniklata L) in bait and traps on lowland rice plants (Orzya sativa L).The purpose of this study was to determine the effect of the use of papaya leaf baits and watertrench traps on the population of golden snail pests on lowland rice plants. The study wasconducted in Taratara 1 Village, West Tomohoon District, Tomohon City. The duration of thestudy is approximately four months, which took place from March to May 2020. The researchmethod was carried out by quantitative descriptive methods with direct experiments in the field.This experiment uses two lowland rice fields consisting of bait and trap. Observations were madeat the age of plants 21 days after planting, 28 days after planting, and 35 days after planting. Theresults of the research on the treatment of bait using papaya leaves an average of 24.8 individuals/ m2 and on the treatment of traps using an average water trench of 31.4 individuals / m2. Thepopulation of golden snail pests in both treatments decreased from plants aged 21 days afterplanting to 35 days after planting. The age factor in plants can increase the height of golden snailpests. Gold snail can easily attack plants by grating the plant tissue and eating it. Because thestructure of the stems, stems, and leaf blades in the plant is still young. Both treatments contributeto positive results, so that further research is needed by combining bait and trap treatments on alarger scale and can be integrated with other environmentally friendly control methods.
