Publisher : Politeknik Negeri Lampung.

The existence of UPJA institute has been known by farmers, especially farmer nirigation land since last 3 decades. UPJA institute which has been known by farmers identical with alsintan managemant to suport agriculture effort, especially rice plant in villages. This resarch was done in two provinces, Central Java and South Sulawesi. The resarch showed score of B/C ratio wich was gained bu using alsintan UPJA reach 2,5=3,5.This score was reached because partisipation of farmer using UPJA more effecient and economic scale more beneficial. On other hand, the perception of alsintan availability was needed as an anticipation to production increasing and lack of labor in villages. So that, existence of UPJA, either managed by group or individually are nedeed as suprot to agriculture work from land management, maintanance, irigation, haverst and post harvest. Beside that, giving security guarante in production proses and to press haverst fail. Keywords: Existence of UPJA, Rice farmer.

Role of cassava in the national economy continued to decline because it is not a priority commodity. As a result, crop acreage is declining and productivity did not increase significantly. This situation also occurred in West Sumatra Province. The cause is not yet precise technology to increase the income of cassava farmers and the diversity of the community's ability to adjust the pattern that has been owned by the available land resources. Meanwhile, demand for cassava will continue to increase along with the continued rise and soaring fuel prices (fuel) in the world market for cassava is one source of bio-ethanol to substitute a premium. This article contains about the problems of cassava and technological support for the development of cassava in West Sumatra. The methodology of writing a book study (literature) on cassava commodity that comes from books, proceedings, journals, papers and others. As a result, the development of cassava in West Sumatra to be directed mainly on dry land agroecosystem. Based on the type of climate and land type, almost all areas in West Sumatra has the potential to be developed as a regional center for cassava production.To improve cassava production strategies are needed, among other things: (1) The addition of harvest area, and (2) Intensification of quality improvement. Addition of harvest area include: (a) opening of a new land, (b) multiple cropping, and (c) increase harvest index. While improving the quality of intensification can be done with the application of several alternative technologies in cultivation, among others: (1) high yielding varieties, (2) preparation of seedlings, (3) land preparation, (4) planting, (5) fertilization, (6) plant maintenance; and (7) harvest. Results of analysis of farming cassava variety Darul Hidayah show farmers the benefits of Rp. 34,110,000, - for 12 months and R/C ratio value = 3.46.

In order to support the needs of the national textile industry, the necessary raw materials of high quality cotton, high grain yield and widely adaptable. To achieve these objectives, it is necessary the introduction of new cotton crop accession so that the resources can be available breeding elders. Given the genetic diversity and varieties of national cotton production stagnant. The study was conducted with the aim of getting the results of evaluation of growth of cotton plants introduced in tropical environments. Based on the analysis of variance, character growth, plant height, number of branches and monopodial simpodial, and time of harvest showed significant differences in the level of 1%. While the character of days to flowering and boll opening age showed significant differences in the level of 5%. There was variation in plant height were heterogeneous due to genetic differences. Differences in flowering dates, age boll opening and harvesting with significant variation is caused by environmental influences. Anticipated environmental factors that have the most primary role is long irradiation, recorded some sensitivity to fotoperiodisitas accession. The results of the study recommend accession CRIS-664 and CRIS-342 as source code elders with early maturity, because it has a lifespan of flowering and harvesting age equal even faster than local cultivars.

Nutrient Film Technique (NFT) is one of hydroponic system with the roots of plants put on a thin layer of water that resembles a film. Circulate the water and nutrients needed by plants. Movement of nutrient solution circulation but because of the encouragement of the pump, is also caused by the slope of the gutter pipes are used. Gutter pipe slope is getting steeper can cause plants to be difficult to stand up straight and nutrients are absorbed a bit because the flow is too fast. The slope of the gutter pipe that is too small can cause nutrient flow easily clogged because the flow is too slow. Therefore, in this study the slope of the NFT gutter pipe used was 1%, 3%, 5%, and 7%. The aim is to determine the effect of NFT gutter pipe slope on the growth and yield of pakcoy. Analysis used to determine whether there is difference in the growth and production of different crops on slopes is ANOVA (Analysis of variances) in one direction because there is only one independent variable, followed by a test of Honestly Significant Difference (HSD) at 5% significance level. The results show that there are differences in average growth and crop production pakcoy using different NFT gutter pipe. NFT gutter pipe slope the best effect on plant growth (number of leaves, plant height, and root length) and pakcoy crop production (weight of the plant) is on a slope of 5%, with the results for each crop is the average number of leaf 9.1 strands, the average plant height 18.4 cm, the average length of the roots of plants 41.5 cm, and an average weight of 34.49 g plant.
