Abstract

Study has been conducted to determine erosion hazard occurring in South Banawa District. This research was conducted in September - November 2017. This study conducted by field observations and was supported by results of laboratory analysis data.  The rate of erosion was determinad by using the USLE (Universal Soil Loss Equation) method developed by Wischmeier and Smith in 1965. The results showed that the erosion hazard occurring in South Banawa Sub-District is very high with the average erosion per year reaches 1,785 ton ha-1 year-1 (medium). Conservation practices are required for reducing the rate of erosion hazard by the estaldishmeat of terraces, contour planting and replanting at lands with a slope above 15%.

Abstract

This study aims to determine the density and diversity of spores of Arbuscular Mycorrhizal Fungi (AMF) at rhizosphere of several plantation crops, such as ; cocoa (Theobroma cacao L.), coconut (Cocos nucifera L.), aren (Arenga pinnata Merr), candlenut (Aleurites moluccana L.),     and bush. Soil sampling was taken by descriptive exsplorative method. Soil samples of rhizospheres of several industrial plants, had been taken from January to March, 2018. Enumerations of spores conducted in Laboratory of Soil Science Department, Faculty of Agriculture, University of Tadulako. Horizontally, the most spores numbers of AMF were found on the rhizosphere coconut in a distance of two meters from stand of plant, that weres 119 spores in 10 g of soil, the lowest spores number were found on the rhizosphere of cocoa in a distance of one meters from stand of plant, that were 15 spores in 10 g of soil. Vertically, the most spores numbers were found on the rhizosphere of aren plant in a depth of 40 cm, that were 98 spores in 10 g of soil. The lowest spore number were found on the rhizosphere of cocoa in a depth of 40 cm, that were 14 spores in 10 g of soil. The analysis of the diversity of colors found there are nine kinds of different colors, includes the yellow clear color, yellow, yellow green, reddish yellow, red, red brown, brown, brown black, and black. The spores are found is dominated by the color of black that is 337 spores, then the color of red being the color of most little found which amounted to a total of 15 spores.

Abstract

Utilization of Moringa is still not well known, normally known as one of the veggie menu. In addition to direct consumption in fresh form, Moringa can also be processed into powder form that can be used as a base material for food products, such as processed cakes,biscuits and other processed. This study aims to determine the concentration of Moringa fruit juice that gives the best effect against chemical and organoleptic properties cake. The research was conducted from January to March 2018 in the Laboratory of Agro-Industry, Faculty of Agriculture, University,of Tadulako. Research using completely randomized design (CRD) and a randomized block design (RBD) the factors which consist of 5 level of concentration, ie 37,5%, 41,1%, 44,4%, 47,3% and 50% were repeated 3 times so that obtained 15 experimental units. Treatment significantly or very real then tested further using honestly significant difference test (HSD) level of 5% or 1%. The results showed that the chemical and organoleptic characteristics of the best there is on the cake with a concentration of moringa juice 50%, with a content of 29.84% moisture, 7.79% protein content, fat content of 23.52%, 0.60% fiber content.

Abstract

Bactrocera sp. is one of the important pests on crops of chili. Losing of the results caused by this pest attack can reach 80%, and even can be 100% if the control is not done immediately. The purpose of this research is to know the influence combination factors of color and the height of the traps on the number of fruit flies trapped in red chili. This research used Randomized Block Design (RBD) with factorial pattern consisting of 2 factors that are first factor consisting of yellow trap (W2), orange (W1), and clear (W3) and second factor is height of trap, that are height above of 50 cm ( T1), height of 75 cm (T2), and height of 100 cm (T3) respectively applied by Methyl eugenol. The research results showed that (W2, T2) (yellow and height of 75 cm) more effective control of fruit flies on Chili, average of  fruit flies trapped at the height and color is as much as 1758, and of the results of the yield from a height and color also effective because the average yield reached 2.28 kg/week when compared with the results of other productions. The use of methyl eugenol is very effective with the high number and variety of fruit flies trapped by 9113 with four types of fruit flies.

This study aims to analyze the income and feasibility of lowland rice farming system on direct spreading seed system. This research has been conducted from July to August 2017. Determination of location is done by purposively with the consideration that Dolago Village is one of rice production area with productivity of 5.09 ton/ha. Respondent determination was done by using simple random sampling method (Simple Random Sampling). Samples taken as many as 31 respondents of farmers' households from rice farmer population in Dolago Village as many as 108 farmers /household with error rate (15%) who work on  paddy. The analysis used in this research is income analysis (π) and feasibility (R/C-ratio). The result of the analysis showed that the average income of rice farmer in one season planting season in Dolago Village is Rp. 10.759.370/1.25ha/ Season Planting or Rp. 8.607.496/ha/ Season Planting. The results showed that Revenue of Cost Ratio (R/C) of lowland rice farming system of direct seeding system in Dolago Village, South Parigi Subdistrict of Parigi Moutong Regency is feasible to be cultivated. This is evidenced by the value (R/C) obtained by 2.21. This means that every expenditure of Rp. 1 will generate revenue of Rp. 2.21.

Abstract

Cocoa (Theobroma cacao L.) is a plant with high economic value, but in its cultivation technique, is inseparable from pest attack, one of which is cacao fruit borer (Conopomorphacramerella). In an effort to control it, can take advantage of soilborne entomopatogenic fungi found in several layers of soil on cocoa plantations.The aims of this study were to determine the type of entomopathogenic fungi and its effect on bait insects (Chrysalis of C. cramerella). The research took place from August 2017 to completion. Sampling was done at Cocoa Plantation then tested further in Laboratory of Plant and Disease, Agricultur Faculty of Tadulako University.This study used Randomized Complete Design (RCD) method consisting of 3 treatments, namely: Soil on horizon O (L1), horizon A (L2), and horizon E (L3) resectively. Isolation of the fungus was done by using bait insects (Chrysalis of C. cramerella) obtained from the field. Identification of fungi was done macroscopically and microscopically. There are 4 genera of entomopathogenic fungi that can be identified which are Aspergillus, Beauveria, Verticillium and Fusarium.The results showed that the percentage of mortality of test-infected fungi in the horizon O was 20 (100%), A horizon was 20 (100%), and E horizon was 15 (60%).
