Publisher : Politeknik Negeri Lampung.

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

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 didnâ€™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

Profitable crop production starts with a weed control program that includes pre-emergence herbicides to deliver long-lasting, residual weed control. Pre-emergence herbicides are applied to prevent the germination of weed seeds. The study was conducted to determine the effect of acetic acid as a pre-emergence herbicide on maize germination. Pots experiment was conducted on August until September 2012. The experimental design used was Completely Randomized Design (CRD) single factor in four replicates. The application of pre-emergence acetic acid at several concentration, i.e. control (no acetic acid) 0%, 10% acetic acid and 20% acetic acid. The result showed that the pre-emergence aplication at 10% and 20% of the glacial acetic acid solution lowered pH were 5,12 and 5,43 respectively at one week after application, so that inhibited maize germination. No shoots and roots were grew. This was due to the increase of electrical conductivity (EC) or electrolyte leakage caused by the high permeability of the damaged membrane of seed. The EC of control treatment was 11Î¼S/cm g, compared to 10 and 20% treatment of acetic acid were 36 Î¼S / cm g and 55 Î¼S / cm g EC respectively. Increasing concentration of acetic acid caused the higher of protein content leaked, i.e. 7,95%, 7,32% and 7,03% respectively for without acetic acid treatment, 10% and 20% acetic acid. Acetic acid also inhibited respiration rate of maize seed, where the higher concentration of acetic acid produced the lower respiration rate, i.e. 31.63 mg/g/hour, 12.38 mg/g/hour and 2,75 mg/g/hour respectively for without acetic acid treatment, 10% and 20% acetic acid. Keywords : Acetic Acid, Maize (Zea mays L.), Germination, Pre-Emergence Herbicide

Maize production in each year tends to decrease. One reason is the weeds. Weeds is animportant issue because it can compete with the main crop that can reduce crop production.The purpose of this research to determine: (1). The effect of weeds species on the growth andproduction of maize, (2). The effect of weed density on the growth and production of maize,(3). Interaction between the type and density of weeds in influencing the growth andproduction of maize. The research was conducted in Natar, South Lampung and WeedLaboratory Faculty of Agriculture, university of Lampung from December 2014 to April2015. The treatments arranged factorial (3x5) in a strip plot design with three replications.The first factor is the species of weed that are Asystasia gangetica, Rottboelia exaltata, andCyperus rotundus. The second factor is 5 weed density that are 0, 10, 20, 40, and 80populations of weeds/m2. If the assumptions are met, the data is analyzed using ANOVA,followed by Least Significant Difference Test (LSD) 5%. The result showed that : (1).Species of weeds affects plant shoot dry weight, the weight of maize cobs, and the weight ofgrain maize but did not affect plant height, number of leaves, plant populations, cob length,cob diameter, and weighs 100 grains. (2). The density of 40 weeds/m2affects weight of 100grains, but the density of 10, 20, and 80 weeds/m2did not affect the growth and productionof maize. (3). There is no interaction between species and density of weeds in influencingthe growth and production of maize.Keyword: maize, weeds, competition
