ABSTRACT
As one of important plantation commodity, rubber contributes to country income, economic growth and job creation. Increasing of the demand leads farmers to increase the productivity. Ironically rubber price is very low since it has low quality. This situation was occurred because of lack of awareness in quality insurance, hereditary conventional processing technique and inadequate processing machine. Some of characteristic of low quality rubber i.e. the dark color, number contamination level, stench, composition, etc. This research objectives was to improve quality of rubber production by using roller mill, dryer and natural coagulant, to gather information about rubber sheet and to analyze about rubber quality. so that the farmer could have an alternative method in rubber processing to increase value-added of productions and would give benefit to ground farming level. The conducted research showed that sheet rubber with twice grinding by using vinegar and liquid smoke as a coagulant produced a thickness of 5-7 millimeters. This is an ideal size for sheet rubber category. On the other hand, Although it slightly smell of smoke, the rubbers produced was not smelly compared to the conventional ones. in addition, average reduction of water content of the rubbers was about 18%.

ABSTRACT
The increasing of wheat consumption is necessary to considerthe local food materials as substitution material. Sago is the potential local food that used as alternative material and rich of carbohydrate. This material can be used as substitution material of wheat in the making of noodles. However, the right amount of sago as substitution material of wheat in the making of noodle is unknowns.The purpose of study was to obtain the right amount of sago flour as substitution material of wheat in the making of noodle. The study was conducted on 6 percentages of sagoflour as substitution of wheat (0%, 10%, 20%, 30%, 40% and 50% of sago flour). The best percentage was determined based on quality of noodle by using organoleptic test. The results show that addition 40% of sago flour was the best percentageas substitution material of wheat in the making of noodle. On this amount, the noodle had a good taste, color, aroma, and texture. From the proximate analysis, the noodles with 40% of sago also had a good value in water content, ash, protein, fat, carbohydrate, and less in micro-bacterial content.

ABSTRACT
Fresh fruits and vegetables is a sub-sector of agricultural that gets attentions of the world community, including Indonesia in the last decade. This is not free from public awareness of the benefits for health owing to their nutritional values. However, they are very perishable and deteriorated easily after harvest. Therefore, the appropriate ways of handling and technologies for maintaining freshness of the products are necessary to minimize loss of the yield and to extend the trading area. Celery is a perishable product and deteriorated easily after harvest. The purpose of this study was to investigate the quality of celery by using hydrocooling method in order to reduce quality loss during storage. Celery was packaged in polyethylene film and put into the water at temperature 10°C and 27°C (room temperature). Another samples were also stored without packaging and hydrocooling as control. The weight loss, water content, chlorophyll, water activity and gas concentration change inside package were evaluated during storage. The results show that the weight of celery increased on the product stored with hydrocooling method, while for control product, the weight of product decreased during period of storage. the water content and water activity of celery was higher on the product stored at 10°C compared with room temperature and control. For celery hydrocooled at 10°C suppressed the degradation of chlorophyll compared with hydrocooling at room temperature and control.The gas concentration inside packaging changed drastically on the celery hydrocooled at room temperature and control, while on the celery hydrocooled at 10°C gas concentration changed gradually. Based on our observation, the quality parameter of celery could observed until day 21 on the celery hydrocooling at 10°C. It indicates that hydrocooling of celery at temperature 10°C could extend the shef-life of product compared with room temperature.

ABSTRACT
It is believed that small-scale farmer is one of essential components in green economic development. In the case of Indonesia, there are approximately 14.25 million (55.33%) of farmers categorized as small-scale who have land tenure of less than 0.5 hectare averagely. Those farmers are necessarily empowered particularly towards green economic development. The study was conducted in December 2014 in two districts (Bandung and Garut) of West Java province. Three sub-districts were purposively selected representing typology of small-scale farmers. It was found that the empowerment of small-scale farmers should be based on its typology which can be clustered into three-group namely subsistence-oriented small-scale farmers, commercial small-scale farmers, and small-scale farmers in transition. Hence, it is recommended that the empowerment of subsistence typology focuses on optimizing the use of limited land size. Meanwhile, the empowerment of commercial typology is implemented through fostering the commercialization benefited for small-scale farmers. Moreover, the core empowerment of transition typology is in the form of improving the skill capacity supporting off-farm agriculture. Those should be initially started from capacity development through education and training both technical (farm operation) and non-technical (managerial) based on green economic development context. Indeed, it is necessary to involve young generation in order to keep sustaining the transformation of green economic development in Indonesia.

ABSTRACT
Increased productivity of rice through proper cultivation techniques such as the application of SRI method is proven to increase rice production. If there is no yield losses due to pests and diseases that high productivity can be maintained so that food security will be realized. Control of potential techniques developed is to use microorganisms ryzobacteria indigenus P. fluorescent, B. thuringiensis, and S. marcescens which is better known as biocontrol agents for control of pests and also has the potential to control seed borne diseases. Ryzobacteria is a bacteria that lives in the soil and are semi anaerobic, allowing these bacteria to live and breed in rice paddies with SRI method of cultivation. Research germination test done Payakumbuh Politani biology laboratory from February to July 2015. Tests conducted on seed germination infected with the pathogen H. oryzae then treated with ryzobacteria. Once it is planted in the home screen and the observed intensity of the brown spot disease. Seed treatment with ryzobacteria on rice seeds infected with brown spot disease caused by the fungus H. oryzae can increase the percentage of germination when compared without giving ryzobacteria and significantly different according DNMRT test at 5% level, there is no interaction between giving ryzobacteria and infection ryzobacteria seed against the percentage of seed germination . Seed treatment with ryzobacteria on rice seeds infected with brown spot disease caused by the fungus H. oryzae can reduce the intensity of the brown spot disease when compared without giving ryzobacteria and significantly different according DNMRT test at 5% level, there is no interaction between giving ryzobacteria and infection ryzobacteria seed the intensity of brown spot disease.

ABSTRACT
Milk industry faced several problems. In the downstream, the problems were lack of feeder cattle, low of productivity, the feed price was high, small-scale industry and un-skilled labour. In the middle-process, the problems were recording system was low, traditional technology, grazing area was limited, lack of working capital and managerial problem. Further, the problem in the upstream were price of feeder cattle was fluctuated and price of milk was low. Because of very complicated problems that mention above, the progress of milk industry is very slow and they only fulfilled 27% of national demand. The goals of this research were 1) To understand the characteristic of dairy cow industry in East Java, 2) to identify and map the main actors involved in the core processes of milk commodity chain in East Java, 3) to observe the principal function of the actors as well as the interaction among the actor. and 4) To analyse the strategy for strengthening dairy cow commodity chain. The research was conducted in Pasuruan and Probolinggo Residence. The number of respondent was 81 persons that consist of input supplier, farmer, trader and processor. The analytical tools were descriptive, actor network analysis, and commodity chain analysis.The results of the research were: 1) During 2006-2013, average dairy cow population in East Java increased 10% per year, 2) The core processes in dairy farming system are input provision, raising, milking, transportation and marketing, 3) the bargaining position of input supplier and farmer were less than the trader and processor. The recommendations were: 1) it was needed to improve the bargaining position of input supplier and farmer through revitalization of the commodity chain in milk industry, 2) the government should force the farmer institution through improving of the farmer cooperatives.

ABSTRACT
One of the efforts to reduce the negative impact of leachate waste in the environment uses adaptive plants with waste in constructed wetlands (CWs), because the method does not require high operating costs and environmentally friendly.The purpose of this study is to examine the influence of the thickness of sand media and the density of Typha angustifolia L against the COD content of waste leachate pollutants removal efficiency in CWs. This research method uses a split plot design at laboratory scale. A statistical test uses linear additive of variance analysis for a randomized group with two factors and one dependent variable. The results of the study of the average influent COD content at the level of between 495.5 mg/L to 598.56 mg/L after experiencing sequential time (7, 9, 11 and 13) days in CWs decrease to 21.83 mg/L to 68.74 mg/L. There is not a significantly (p = 0.158 > 0.05) influence the thickness of sand media to the COD removal. The COD removal efficiency is significantly (p = 0.00 < 0.05) influenced by the density of Typha angustifolia L plant. The highest removal efficiency is selected on density 36 plants/m2, occurring in the thickness of sand media of 55 cm with the removal at the level of between 88.99 % to 95.96 %.
