Rubber plant productivity is affected by production factors such as amount of labour, amount of land area, number of productive tree, manure and rainfall. Production factors must be controlled to meet optimum rubber production, due to the increasing need of rubber. Rubber consumption on 2009 is 9,277 millions ton, while on 2010 increase become 10,664 millions ton. World crude rubber is able to provide 9,702 millions ton on 2009 and 10,219 million ton on 2010. Factor that influence rubber harvest result is the benchmark to get the decision to support the rubber achievement harvest optimally. The purposes of this research is to know and forecasting the harvest result of rubber production in PT Perkebunan Nusantara IX (PTPN IX) Sukamangli estate in the future i.e. 2015, 2016 and 2017. This research used descriptive analytical method. The data analysis used forecasting with ARIMA analysis. The base on ARIMA model, forecasting result for rubber production in 2015 amounted to 325675.9 kg (Quarter I), 396571.3 kg (Quarter II), 338552.1 kg (Quarter III), 258359.4 kg (Quarter IV). In 2016 amounted to 356854.6 kg (Quarter I), 442136.9 kg (Quarter II), 387335.1 kg (Quarter III), 293983.5 kg (Quarter IV).

Alfalfa plant in Indonesia its not easy to produce flowers and seeds. Flower production is also affected by cutting the apical bud. At this time there is no research on the effect of cutting the length of the apical bud of the flower and seed production of alfalfa, both in quantity and quality. Thus this study examines the apical bud cutting the length of the seed production and alfalfa leaf chlorophyll content. The purpose of this study was to determine the most optimal length of the apical bud cutting to produce optimal growth and production of alfalfa seed. Outcomes and benefits of this research are: a). Provide information for other researchers on seed production and alfalfa leaf chlorophyll content were treated with different apical bud cutting, which will carry out further research. b). Provide recommendations to stakeholders on the apical bud cutting the most optimal for alfalfa plants that produce highest seed production and alfalfa leaf chlorophyll content. c). Providing information for farmers and researchers on alfalfa seed development opportunities for the tropic zone. Research using randomized complete block design with four replications. This study was a single-center trial with a treatment of various lengths cutting apical bud. Apical bud cutting long treatment include without cutting, cutting apical bud length of 5 cm, 10 cm, 15 cm, 20 cm and 25 cm from the ground. When cutting is done when the plants aged 6 weeks after planting. The results of the study showed that the alfalfa plant leaf extract can be produced which is solid green chlorophyll that has the potential to be used as raw material for the manufacture of supplement health drinks. Alfalfa flower has emerged in the 4th month, this occurred in the treatment of cutting 5 cm. It shows the probability that the flower has the potential to develop into seeds.

This study aims to determine the socio-economic characteristics, land area and income of farmers affected milkfish rob and abrasion in the village Sidogemah Sub-District Sayung Regency Demak. The area was chosen as a test site set deliberately, based on consideration of the area that the vast amount of the most extensive fishpond to day. Sampling was done by the method of census respondent, where each element of the population that is being recorded and given a chance of being selected in to the sample. Socio-economic characteristics of fish farmers based on descriptive analysis that fish farmers their views of live area still productive but education is getting old and is still 12 years old, old enough experience and the number of family members on average more than 5 people. A decrease in land area of 2,40 ha fishpond before exposure to rob and abrasion exposed to 1,77 ha after rob and abrasion. Total cost increases on farm land that has its own land of Rp 543.011,16 to Rp 840.231,82 and palso which has leased land from Rp 765.745,76 to Rp 1.062.966,42, resulting in decreased before exposure to rb acceptance or Rp 2.931.923,08 and after exposed to rob Rp 2.801.636,90. A reduction in income milkfish farmers who have their own land of Rp 2.388.911,92 prior to exposure to rob and abrasion to Rp 1.961.405,08, also on fish farmers who have leased land from Rp 2.166.186,32 prior to exposure to rob and abrasion Rp 1.868.956,66 after exposure to rob and abrasion of the land area of 1,77 ha fishpond/person.

Food security (food security) is a paradox and is more of a discoveryof the modern world. Food security should include the availability,distribution, and consumption. Agricultural development has a commongoal of promoting agribusiness, namely by building a synergistic andharmonious aspects: (1) upstream agricultural including seed, otherproduction inputs and agricultural machinery, (2) primary agriculture (onfarm),(3) agriculture downstream (processing), and (4) support servicesrelated to the advance of agribusiness. National Food Security must not beseparated from domestic food security / local. With reference to the matter,with the regional autonomy is expected to maximize the role of localgovernment in improving the agribusiness sector in achieving national foodsecurity. In addition, the restrictions on imported products is also one thingthat must be taken into consideration by the government, the diversificationof agricultural land into residential and industrial land is also a significantobstacle to the achievement of local and national food security, so it must bethe limit. Development of agriculture technology also is expected toimprove and streamline the agricultural sector. Diversification of FoodProduction in a way to diversify food consumption or to reduce the pressureon the availability of a range of food products, especially rice in Tunjangwith consumption patterns, The Role of Agricultural Research andDevelopment Agency were also in demand to provide new breakthrough tothe perpetrators in the agribusiness sector which will bring progress andrealization of national food security.
