The purpose of this research is to know the aspect labor absorption and prosperity level in dry agroecosystem. This research was taken in PATANAS (Panel Petani National) villages including dry agroecosystem 2008. The data was analyzed by simple statistic and showed using cross tabulation analysis. The result is show that labor absorption in villages is still dominated by agriculture sector, which is changing from under elementary school. Beside that, labor force absorption for younger age is increasing which is showed by movement of the amount of labor from agriculture sector to non agriculture sector. In other hand, the development of prosperity level in the villages is varieties, among in 3 villages no prosperity and 5 villages is prosperity. It means that the availability of labor force which absorption different means of livelihood and the revenue in agro ecosystem wet land didn?t show any development than agro ecosystem dry land villages. So that policy to increase farmers property is needed through variety aspect to support revenue development in agriculture and non agriculture sectors, and agriculture commodity price policy which suitable for farmers and also push work climate out of agriculture Keywords : labor structure, prosperity level household

Gambier is thespecific commodity of West Sumatra. The research was aimed to find a description of gambier agribusiness, potential and constraint to improve and increase productivity and farmer income. This research on the profile of gambier agribusiness was done on March-October 2015 in Limapuluh and Pesisir Selatan District as the central produce of gambier in West Sumatra. The survey used for data collecting from 30 farmers and 10 merchants according to its level selected at random. Data were analyzed using descriptive, marketing system and economics analysis. The results showed that planted area of gambier increased but production have fluctuation from year to year. Cultivation technology of gambier very simple and without fertilizing. Productivity is 0.70 t/ha/yr. Gambier were exported to various state especially India, Pakistan and Singapore. Price and quality of gambier determined by the merchant. Nationally market compartment export gambier from West Sumatra more than 70.0%. The share of farmer price is 43.1% less than margin share about 56.9%, its mean marketing system inefficient. Profit of gambier is low because ofhight cost of processing, but still feasible with B/C=1.53. Suggest to policy maker and farmer to: (i) Push the growing micro and small industry to produce secondary product of gambier; (ii) Improve of subsystem produce through applying of innovation, development of appliance simple innovation to processe of gambier; (iii) Farmer group alliance institution (gapoktan) pushed to grow marketing unit and warehouse scrip certificate system by exploiting fund in Micro Financial Institution of Agribusiness (MFI-A) and village funds. Expected, for next time the farmer does not depend on raw material exporting of gambier. Keywords: export, marketing, micro industry, productivity, profit, gambier

Conventional tillage system practices for a long time can reduce soil qualities because of soil erosion, soil compaction and depleting of soil organic matter. Conservation tillage such as No-tillage system can be applied as an alternative technique to rehabilitate soil degradation problems.. This research is a part of a long term study of soil rehabilitation that was conducted from 2010 till now, in PT GMP, Central Lampung. Sampling of nematodes was done on April 2013 when the second ratoon RGM 00-838 variety of sugarcane was 9 months old. The aim of this research was to study the effect of tillage and mulching systems on the abundance of several dominant plant parasitic nematodes. Split plot experimental design was applied on this research. Tillage system as the main plots consisted of intensive tillage and no-tillage systems, while mulching system as the sub-plots consisted of no-mulch and mulching with 80 ton ha-1 of fresh bagasee. Nematodes were collected from 0-20 cm deep of soil and extracted by sieving and centrifugation with sugar solution methods at the Plant Pest and Disease Laboratory, University of Lampung. The results of this research showed that there were eleven plant parasitic and seven free-living nematode genera inhabited the PT GMP sugarcane plantation. The three plant parasitic nematode genera dominant were Hoplolaimus, Xiphinema, and Hemicriconemoides. No-tillage system effectively reduce the abundance of Xiphinema and , mulching with bagasse reduced the abundance of Hemicriconemoides. Meanwhile, mulching on No-tillage system more effective to reducing the abundance of Hoplolaimus compared to intensive tillage system. This results suggested that the No-tillage with bagasse mulching system was one of alternative techniques to control plant parasitic nematodes pest of sugarcane plantation. Keywords : Tillage, mulching, sugarcane, plant parasitic nematodes, abundance.
