Abstract

Onion (Allium ascalonicum L.) is one of the commodities that potential especially in the city of Palu. However, in cultivation, red onions have a lot of problems especially L.chinensis pests. The purpose of this study was to determine the effectiveness of using yellow sticky traps and pesticides in controlling plant LASEKI L.chinensis the crop shallot Local Palu. This study uses a randomized block design tersiri of 2 factors and repeated 4 times. The first factor is the concentration of insecticide LASEKI plant consisting of 3 levels ie: L0 = no LASEKI vegetable insecticides, L1 = 5%, L2 = 10%. The second factor is the use of traps consisting of 2 levels ie P1 = use yellow sticky traps, P2 = The use of transparent sticky traps. Based on those two factors, the obtained 6 treatment combinations with 4 times as many replications. Each treatment there were 10 clumps, so there are 240 family units experiment. The results showed that there was no interaction between treatment sticky traps (P) with botanical pesticides LASEKI the number and amount of imago L.chinensis were caught on sticky traps. Treatment with vegetable insecticide concentration LASEKI 5% (L1) and 10% (L2) is effective in suppressing the number korokan L. chinensis and also effectively increases the production of onion crop. The use of yellow sticky traps (P1) effectively reduces the number of L. chinensis who snore leeks.

Abstract

The aim of the study was (i) to analyse the income of oil palm farm of the Iga and Plasma groups, and (ii) to analyse the comparation of the income of oil palm farm of the both of groups.  The respondents were farmers of oil palm of the both of groups.  The respondents were taken by technique of unproportionally stratified random sampling.  There are 130 population of the farmer of oil palm whom consist of 60 farmers of the Iga group, and 70 of the Plasma group.  For every group was taken 15 respondents as sample.  Methods of analyses  used were the analyses of income, and the analyses   of comparation.  Analysis results showed that the average income of Iga group  of oil palm farmers was greater than plasma group, i.e. IRD 2.13 million per ha vs IRD 1.71 million per ha.  Thus, there was sifnificantly difference between the income of Iga group and Plasma group.  It was indicated by t-hit > t-tab(?=1%; df=29), i.e. 19.356 vs 2.763.  It means that Ho is rejected, and H1 is verified that there was sifnificantly difference between the income of the both groups that the income of Iga group of oil palm farmers was greater than plasma group

Abstract

Along with the discovery of several gold prospects area in ??Central Sulawesi, gold mining had increased both by companies, cooperatives and illegal mining. The activity of this mining produce waste that consist of hazardous toxic substances in which there was a heavy metal such as mercury (Hg). This metal is one of the trace elements that has liquid at room temperature, high specific gravity and power electric conductivity, and a toxic chemical element became a global concern because has significant hazardous effect on human health, wildlife and ecosystems. This study was  aims to know the content of mercury in soil around the Poboya?s gold mining. The method used in this study was a survey which describes the actually condition of this area and assess the causes of certain symptoms. In this study measurements, field observations, and laboratory analysis had been done. There step that be noticed in this survey were pre-survey, main survey (sampling) and laboratory analysis. Compose soil sample for laboratory analysis had been collected from several sample point that had been plotting by tactics. The results of this study showed that the content of mercury in all representative soil sample and tailings had highest than threshold. Normally, concentrations of mercury in the soil range from 0.03 ppm (normal) to 0.3 to 0.5 ppm (critics); while concentrations of mercury in soil agricultural areas ranged from 0.057 ppm to 8.19 ppm and in tailings ranged from 84.15 ppm - 575, 16 ppm.

Abstract

The research was conducted in the Soulowe of village, District Biromaru, Sigi. Experimental design used was Randomized Block Design (RBD) with 3 (three) treatments and 5 (five) replications, in order to obtain 15 units of the experiment.  Each treatment is based on the differences in varieties. These varieties are varieties Bonanza, Paramita and Kumala. The variables measured were the intensity of the attacks and the rate of infection diseases. The first observation made at the time the plant was 14 days after planting, subsequent observations made at intervals of once a week as much as 7 times. The results of this study showed that the difference in response of resistance varieties Bonanza, Paramita and Kumala against downy mildew caused by the fungus Peronosclerospora maydis. The highest attack intensity was found in varieties Bonanza followed by Kumala varieties, while the lowest was found in varieties Paramita. The highest disease infection rate was varietas Bonanza, then followed by Kumala varietas, and then Paramita varieties that have the lowest disease infection rate.

Abstract

This study aims to determine the level ofrice farming income and feasibility, and to know the development of Subak Baturiti in Balinggi Village, District of  Balinggi, Parigi Moutong Regency. Respondent sampling is conducted purpossively. The number of respondent farmers taken in this study is 40 of 66 farmers living in Subak Baturiti. The analyzes used in this study are income analysis, feasibility analysis, and descriptive analysis. Results of  those analyzes show the average rice production is 6.005,75 kg of harvested dried grains (HDG) and the average revenue received by the farmers is Rp 18.017.250,00 per farming unit (1,3 ha)/ growing season (GS) or Rp14.242.885,38/ha/GS, where as total costs spent by the respondent farmers are an average of  Rp 12.692.780,18 per farming unit (1,3 ha)/GS, or Rp 10.033.818,32/ha/GS and th rice farmin revenue is Rp 5.324.469,83 per farming unit (1,3 ha) or Rp 4.209.067,06/ha/GS with R/C value = 1,42, showing that R/C value is higher than 1 (R/C > 1). Therefore the farming is favorable (additional benefit or revenue is higher than additional cost). Subak Baturiti is an organization of water user farmers, and implements the Tri Hita Karana Concept that there are interrelationships between human beings and God, between human beings and environment, and between human beings and their others so as the farming activities will go well dan harmoniously.
