Abstract

The easiness of rice processing is a challenge for the processed instant corn rice so the consumers can easily cook corn rice. In order to increase value added of corn rice as functional food, then rice bran can be added. The aims of this research were to determine the optimal composition of rice bran substitution in the production of instant rice bran- corn rice and to determine the characteristic of instant rice bran-corn rice. This research used Respond Surface Methods (Design Expert 9 Programs) which obtained 13 running formula. The formula provided an optimal solution at 0,900 level of desirability which treatment amount of rice brand by 9% and no soaking treatment. According to solution of program, resulted the characteristic of instant rice bran - corn rice with water content 2.58%, bulk density 45.9 %, porosity 87.3%, development volume 254% dan water absorption 206%.

Abstract

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.

Abstract

This research were aimed 1) to study the effected phonska dosage to growth and yield of shallot in rainy season, 2) to study the effected varieties to growth and yield of shallot in rainy season. The research was implemented at Berbah, Sleman for February April 2015. The research used design of split-plots by 3 replication. The main plot was phonska doses (P) i.e P1= 100 kg/ha, P2= 200 kg/ha, P3= 300 kg/ha dan P4 = 400 kg/ha. The sub plot were varieties (V) i.e V1 = Bima, V2 = Tiron, V3 = Crok Kuning. Observation was conducted to plant height, leaves number, fresh weight per cluster, dry weight per cluster, Stover weight per hectare, fresh bulb weight per hectare, dry bulb weight per hectare, bulb diameter and harvest index. The data obtained was analysed by variance analysis with 5% level of significance. The results of research showed that didn't interaction to phonska dosage and varieties to all parameters. The increasing phonska dosage didn't affected significantly to all growth and yield of shallot. Varieties affected significantly to growth and yield the shallot. The highest productivity in rainy season was Tiron varieties i e. fresh bulb weight per hectare (107,1 kw/ha) dan dry bulb weight per hectare (96,7 kw/ha).

Abstract

This research was intended to identify productivity and income of corn farming in dry land at Sumbawa Regency. It used descriptive analysis method. The research was done with survey technique. Sample was taken using random sampling with 100 respondents. Research site was determined purposively in Labangka district. It used Cobb-Douglas production factor analysis and financial analysis (cost, revenue and income). The result indicated that average productivity was 6.092 ton/ha with average cost of Rp 2,912,994/ha, average revenue or 13,392,755/ha and average profit of 10,479,762/ha. Factors affecting production significantly are seed amount, urea fertilizer amount, insecticide amount, experience in corn farming, and activeness in extension program. R/C ratio of 4.6 means that corn farming in dry land in Labangka district is profitable and feasible to continue.

Abstract

The agricultural sector has the heavy burden of being perceived as levers of national economic growth. As a consequence, to pursue short-term interests of many agricultural development practices carried out by ignoring the preservation aspects of natural resources. These conditions raise awareness about the importance of conserving natural resources as a factor of production increase agricultural productivity. Agricultural development should be directed through the right strategy with not merely the pursuit of economic growth, but by taking into account aspects of sustainability of agricultural resources. Therefore, it is time for the government continuously campaign and implement approaches to agricultural development that is integrated, environmentally friendly, efficient, sustainable, future-oriented and long-term.

Abstract

This study aimed to know the role of institutional bureaucracy in the implementation of integrated pest management. The study was conducted in April 2012 in central Java. IPM institutionalization efforts in Indonesia influenced by a lot of constraints such as constraints conceptual, institutional structures, program priorities, ego-sectoral and ego-discipline and empowerment of farmers. Strategies undertaken by the government is the institutionalization of plant protection, the development of management information systems, strengthening forecasting and observation, the provision of appropriate technology and site-specific duna, provision of protection and stabilization of pest control. The role of institutional bureaucracy in the implementation of IPM in central Java is not optimal because of weak cooperation and coordination among stakeholders as well as good organizational structure has not stabilized both central and local levels as a result of regional autonomy policy. Collaborative efforts and networks need both locally, nationally and globally. Cooperation and networking will provide additional information as a result of the activities of the exchange of information related to IPM.

Abstract

Research conducted on the characteristics of the land soil type Regosol, sand texture argillaceous, a height of 114 m above sea level, the type of wetland with cropping pattern of paddy-rice-crops, irrigation systems semi technical, in the planting season 3, the former rice plant gadu, in the village of Sumberharjo districts Prambanan special region of Yogyakarta Sleman district. A study in May 2013 in November 2013. Methods Complete Randomized Block (RCBD), 3 NPK treatment, repent 6 times, 18 plots, a plot area of 1000 m2. Materials used three types of fertilizer NPK (Formula I: Phonska; Formula II: Pearls; Formula III : Tablets ), Ketan Kutuk rice seed Local superior. Implementation of research, planting mode SRI, cropping system tiles, a dislance of 20 x 20 cm, fertilization principled 4 ringh (type, dose, method, tame). Basic fertilization: before planting time, type of super petroganik 640 kg, 10 kg ZA, distributed way. Fertilization aftershocks 1 : 21 days, the type and dose of fertilizer every 4 clumps that (Phonska 5 grams; 5 grams of Pearl; and Tablets 2 point (5 grams), means embedded in the soil. Fertilization aftershocks 2 = age 40 days after planting, the type and dose of Urea 10 kg, carat deployed. Plant maintenance according per formed by local farmers. The results showed that treatment types of NPK 3 formula (Phonska, Pearls, Tablets) no real effect on plant height, weight of wet hay, straw dry weight, weight of 1000 grains, number of grains per panicle, and the weight of dry milled grain. Real effect and significant fly different DMRT 5 % treatment types of NPK fertilizer to the number of productive tillers. Local superior rice Ketan Kutuk to respond to various types of NPK 3 formula (Phonska, Pearl, Tablets) with productivity (4,275 ton/ha; 5,5 tons/hectare; and 4,140 tonnes/hectare)
