This study is a survey research on Acceptance Analysis of Information and Communication Technology (ICT) for Extension Workers in Agricultural Extension Activities. The research objective was to determine the effect of variable Perceived Ease of Use of ICTs on Perceived Usefulness use of ICT, the influence of Perceived Ease of Use of ICTs on Intensity Behaviour Using ICT, influence perception Usefulness use of ICT to the intensity of Behaviour Using ICT, and the influence of Intensities Behaviour Using ICT to the use of ICT in Currents. This type of research is explanatory research by using the Technology Acceptance Model (TAM), and involve agricultural extension workers as respondents. Data were collected using questionnaires and then analysed by quantitative descriptive and hypothesis testing and regression analysis. The results of the study are (1) the results of descriptive analysis of the four variables are variables Perceived Ease of Use of ICT, variable Perceived Usefulness use of ICT, variable intensity Behaviour use of ICT, and variable use of ICT In Currents has an average category High, (2) Test Results Hypothesis analysis simple linear regression, namely: (a) for the variable Perceived Ease of Use ICTs to variable Perceived Usefulness use of ICT, and variable Perceived Ease of Use ICTs to variable intensity of the use of ICT has a significant influence (b) While the variable Perceived Usefulness Using ICT to variable intensity Behaviour of Use ICT, and the variable intensity of Behaviour Using ICT to variable use of ICT in Currents not significant. The implication of this research is very necessary in their outreach activities using ICTs to improve the success of the field of education, and what is important is the use of ICT must be effective and efficient.

The aim of this research is to determine the best proportion of the unfermented cassava waste and cassava starch on development and adsorption power and sensory quality of “cassava rengginang”. The research method using a design structured factorially composed of two factors; the first was the added cassava waste consisting of five levels symbolised with (A) i.e. A1 = 30%, A2 = 40%, A3 = 50%, A4=60% and A5 = 70% and the second was the addition of cassava starch consisting of 5 levels symbolised with (C) i.e. C1=70%, C2= 60%, C3= 50%, C4 = 40% and C5= 30%. The observed variables are the sensory quality of the produced cassava rengginang including texture, colour, flavour and taste. The development power and the adsorption power were measured by comparing the perimeter and weight of the crude(unprocessed) and the fried (processed) cassava rengginang respectively. The cassava rengginang that is most preferred by the panellists with the highest development power off 61,49% is the combination of A2 C2 using a proportion between cassava waste and cassava starch of 40:60. The lowest oil adsorption power of 34,55% is shown by the combination of A1C1 with a proportion between cassava waste and cassava starch of 30:70 while for the sensory quality of texture, flavour and taste is shown by the combination A2C2 with a proportion between cassava waste and cassava starch of 40:60, whereas concerning the colour, the combination A1C1 is most preferred with a proportion between cassava waste and starch of 30:70. Keywords: Cassava Waste, Development Power, Adsorption Power and Sensory Quality of “cassava rengginang”.

A study was conducted to investigate the effect of antagonistic microorganisms and dose for the damping off control in spinach that were carried out in Banguntapan village, Banguntapan sub-district, Bantul district, from July to September 2016. The study used a complete randomized block design consisting of 5 treatments in the control of damping off, fungicide propineb, Rhizobakteri, Trichoderma sp, mixture of Trichoderma sp and Rhizobakeri with replication 4 times each treatment. The application is done by watering the land one day before the spinach seeds are planted, while the observation is done from the seeds planted until the plant is 30 days with 3 days interval. The results showed that the control treatment with the mixture of Rhizobacteria and Trichoderma sp concentration of 3 millilitres in 1 litter water showed effective results based on the analysis of the incubation period, the percentage of attacked plants and the intensity of the attack.

Soybean rust disease is caused by Phakopsora pachyrhizi Syd fungus. It was important because the disease was contagious and there is always an attack in soybean farming, resulting in yield loss varied from 10-70 percent, but most farmers did not conduct controlling due to the expensive price of synthetic fungicides. In nature there are many mineral materials and plants that are toxic to microorganisms, further research in order to know the type of natural ingredients and effective doses in controlling rust diseases on soybean was carried out in the Banguntapan village, Banguntapan district, Bantul regency, from March to October 2015. Research was performed using randomized complete block design comprises 5 treatments use natural ingredients for controlling rust disease of soybean were clove oil (3 cc / l of water), prusi (CuSO4) and lime [Ca (OH)2] solution mixture, sulphur (S) with lime, salt (NaCl) solution with a concentration of 3 grams / l of water and water as a control, with replication as many as 4 times each treatment. Application is done by spraying the leaves beginning the age of 14 days after planting to 70 days with an interval of 7 days. The results showed that treatment with a mixed solution of prusi control with lime concentration of 3 grams in 1 litre of water showed effective results based on the analysis of the incubation period and percentage of diseased leaf and can reduce the intensity of rust disease by 26.84 percent. Keywords: soybean rust disease, prusi, the intensity of attack

The research aims to know treatment combination influence of media composition, media thickness, and paddy seeds density on the result of planting seen from the seed amount per hole, plant depth and level of clumsiness with indojarwo trans planter 2: 1. This research was conducted in Celeban, Agricultural Extension College, Yogyakarta. This research was performed from October 30, 2016 to November 17, 2016. The research method arranged in base pattern Randomized Complete Block Design, consisting 3 factors. The first factor is the composition on media (P), consists of 3 level types, soil 1,5: compost 0,5 (P1), soil 1: compost 1 (P2), soil 0,5: compost 1,5 (P3). The second factor is the thickness of media (M), consists of 3 types, media 1 cm and cover 0,5 cm (MI), media 1,5 cm and cover 0,5 cm (M2), media 2cm and cover 0,5cm (M3). The third factor is the density of paddy seeds (K) consists of 3 types, 60 g/ dapog (KI), 70 g/ dapog (K2) and 80 g/dapog (K3). Each combination receives 2 times treatment, total 54 units of treatment. Statistical analysis was conducted to determine the influence difference between treatment with diverse examination 5% and 1 % and to know the real difference between treatments with 5 % DMR test. The result of the research combination treatment of comparison/ composition seedlings media (P), media seedlings thickness (M), and seed density (K) had no significant effect on the average number of seeds per hole, the average plant dept, and average of seed stands on rice plant.
