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

The decreasing of Bitter Melon production in Tojo Una-Una regency is not only caused by the lack of fertilizer distribution but also lack of cultivation because the level of pest attack is very high. Soil fertility decrease caused by several factors, they are lack of farmer knowledge about the rest of the crop cultivated such as rice straw, bitter melon and other plant species. Therefore, the research was conducted using growth regulator of Gibberellins Synthesis Gibro 10SP with active ingredient of Gibberelic Acid of 10% to set the growth and yield of Bitter Melon . The objective of this research is to find out the effect of Gibberellins Synthesis Gibro 10SP with active ingredient of gibberelic acid of 10% in each sachet to growth and production of Bitter melon, to reduce the use of inorganic fertilizer in Bantuga village of Ampana Tete District of Tojo Una-Una regency and conducted from May to July 2016. The research design used a block randomized design with one factor is the ratio of Gibberellins Synthesis concentration. G0: Control, G1: 30 ppm GA3 Synthesis/liter water, G2: 40 ppm GA3 Synthesis/liter water, G3: 50 ppm GA3 Synthesis/liter water, G4: 60 ppm GA3 Synthesis/liter water, and G5: 60 ppm GA3 Synthesis/liter water. The concentration with 6 treatments was repeated 3 times, so the total number of research units were 18 units. The variables observed were number of leaves, stem diameter, age during flowering,       length of fruit, age at harvest and weight of fruit. Total for 3 times harvest of Bitter Melon with 175 land area of research is 38  or 38,000.00 . If the land area is 1  then it is obtained the result of 2,171

Abstract

This research aims to find out the applications of nitrogen fertilizer on the growth and yield of sweet corn and to get a better dose of nitrogen fertilizers  for the growth and yield of sweet corn and usefulness of this research as an information to farmers to develop and increase crop yields of sweet corn through the use of nitrogen fertilizers and can add a reference to the science of various doses of nitrogenous fertilizers in the cultivation of sweet corn. It used randomized complete block design (RCBD) with seven treatments, namely: without urea (N0), urea 50 kg ha-1 (N1), urea 100 kg ha-1 (N2), urea 150 kg ha-1 (N3), urea 200 kg ha-1 ( N4), urea 250 kg ha-1 (N5), urea 300 kg ha-1 (N6). treatment was repeated three times to obtain 21 experimental units. The research found that the nitrogen fertilizer application very significant effect on all components of observation, several dosages of nitrogen increases the growth and yield of sweet corn. Application of the fertilizer urea 250 kg ha-1 produced better yield with the lenght of the cob (31.44 cm) and weight of the cob (10.048 ton ha-1) and same result with dosage of urea 300 kg ha-1.

Abstract

Tapioca flour is one of the products processed by cassava which is widely used as the main raw material and auxiliary material in several food products both in the household and industry. The purpose of this study was to determine the effect of the adding of different tapioca flour, which gives a fluffy taste to raskin rice through testing of chemical and organoleptic. The research method used two types, namely completely randomized design (RAL) and randomized block design (RAK) with five treatments and each treatment repeated 3 (three) times so that there are 15 units of experiment every treatment contained 200 g of raskin rice, if five treatments meant that rice would be used as much as 1 kg. the treatment that will be used is P0 = (without treatment) 200 g of raskin rice and tapioca flour as per the concentration given to P1 0.4g, P2 0.8g, P3 1.2g and P4 1.6g. Chemical properties test results with the addition of tapioca flour in the water content test with the addition of 1.6, ash content with the addition of 0.4 and digestibility with the addition of 1.2 gives effect to the acceptance of raskin rice and organoleptic test of color, aroma, taste, texture and preference with the addition of tapioca flour 1.6 give a very significance on the acceptance of raskin rice.

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.
