The research was aim to study the effect of NaCl on callus of sugarcane varieties Bululawang. This experiment has been conducted in Tissue Culture Laboratory of the Faculty of Agiculture, University of Jember from December 2012 to Mei 2013. The experiment which consists of four levels concentration of NaCl : 0 g/l (K0), 4 g/l (K1), 8 g/l (K2), 12 g/l (K3), and 16 g/l (K4). Each treatment consists of four replications. The experiment consisted of three stages: callus induced, salinity strees of callus, and shoot regeneration of sugarcane on various rate NaCl. Observations conducted qualitative description of the parameters of the color of callus , callus structure and shoot regeneration. The results of this experiment indicated that the callus of sugarcane varieties Bululawang experienced salinity stres of NaCl at 4 g/l showed symptom degradation of color to yellow with sticky crumb structure. Increasing consentrations of NaCl 8-16 g/l lead callus color being tawny until black with sticky crumb structure. Salinity stres with consentrations of NaCl at 4 g/l caused callus is not able to regenerate to form buds and increase callus cell death.

Development of upland rice is one of the answers in increasing rice production, but the productivity of upland rice in Banten is still very low. One reason is the low use of improved varieties. But of the manyÂ upland rice varieties are not all suitable to be developed in a region. ToÂ find suitable varieties are developed in a region need to be Â an assessment of the introduction of varieties to obtain location-specific adaptive varieties. Assessments conducted in Cisehreheun Village, Cigeulis Sub district, Pandeglang District, during Â June-September 2013. Assessments using aÂ randomized block design with upland rice varieties as treatment used are Â Inpago-4, Inpago- 5, Inpago- 6,Â Situbagendit, Stone Tegi and local varieties as a comparison, each variety was repeated Â 4 times. Â To determine the feasibility of technology to analyze revenue and cost Â (B/C), while for Â measuring the level of technological excellence Â applied to farmers to use Â marginal benefit cost ratio analysis (MBCR). The results showed that varieties Inpago 5 generate Â the highest production (3.5 t/ha). The results of financial analysis shows Inpago-5 provide the highest Â profits Â with a gross value of B/C 2.18 Â and the marginal value of B / C of 4.69.. Based on the results of the study, varieties Inpago-5 is a decent variety of adaptive and developed by farmers.

The research aimed to know the influence of competition with weeds K fertilizer on the growth and yield of green bean plant, has been held in the shadow home Crop Science Study Program Graduate of Sriwijaya University, from September to December 2010. The designs used in this study were factorial randomized block design with three replications. The first factor is rhizome reeds: R1 = 0, R2 = 2, R3 = 4, R4 = 6, R5 = 8 rhizome polybag-1. Factor II doses of fertilizer K, K1 and K2 = 0 g = 1.25 g KCl polybag-1. The results showed that the growth and yield of green beans decreased with the increasing number rhizome weeds that compete, either with or without fertilizer K fertilizer K. But with the growth and yield of K fertilization gives better results than without fertilizer K.Key words: competition, weed, fertilizer K, green beans

ABSTRACTThe celery plant well known as herbs especially because of celery’s odor and it also have a lot of positive impact to health, for example antidiuretic, antiplasmodic and antiinflammatory. This impact because of celery secondary metabolite one of them is diosmin. The non-optimum plant growthenvironment will induce secondary metabolite production. This research aim is to find the plant medium that will produce most diosmin content. Celery was planted on six kind of plant medium that was dolomite lime andosol, compost andosol, sand andosol, dolomite lime podsolic, compost podsolic and sand podsolic media. Six weeks after growing in a green house wich temperature 27,3 0C. Selery was harvested and dried on the oven. Futhermore the diosmin content was measured qualitative by TLC and Quantitative by HPLC. The highest diosmin content is 1754,90 ppm showed on dried celery from dolomite lime andosol media, from dolomite lime podsolic media is 1424,57 ppm, from compost andosol media is 1134,2 ppm and the lowest from sand andosol.Key words: celery, diosmin, plant media, HPLC

This research aimed to assess the effect of alternative plant growth regulators to the growth of stum dorman see rubber Klon BPM 24. This research was done at Lubung Saung Village, District And Banyuasin III Regency South Sumatera Province. This research used a randomized block design with five treatment and five replications. The treatments studied were B0 = 0 ml L-1 control, B1 = 2 ml L-1 of water, B3 = 6 ml L-1Â of water, B4 = 8 ml L-1Â of water. Each treatment consisted of 10 plants, with a long soaking the whole treatment was 15 minutes. Thus obtained 25 combined treatment. Each unit experiments were 3 examples of plans. Parameters namely speed sprout observations (HST), shoot length (cm), number of leak stalk (strands), the percentage of seedlings grown (%), weight wet plant (g),Â dry weight of plant (g), weight of wet roots departure (g), and root dry weight (g). Based on result obtained it can be concluded that, the concentration of growth regulators treatment 0f 8 ml L-1 water tends to give the highest yield and better seed to grow that percentage to 80 %, the speed of growth was 20.40 HST shoots, shoot length was 30.79 cm, weight was plants dry weight 7.10 g, wet weight was 1.94 g root, root dry weight was 0.88 g.

The research was conducted to explore and determine the presence of antagonistic bacteria on banana plants (Musa spp) to inhibit (Fusarium oxysporum f.sp. cubense). The research was conducted in the laboratory of Agroekoteknologi, Faculty of Agriculture, Sultan Ageng Tirtayasa University. The experiment was arranged in non-factorial Randomized Completely Design (RCD) using 3 replication. The treatment consisted of 9 rhizobacteria isolates acquired from rhizosper of roots of banana on first screening. The test results showed antagonistic in vitro testing is able to inhibit the mycelium growth of Foc where the greatest inhibition was shown by BR 45 and BR 15 with the largest percentage inhibition of 88.90% and 87.78%. Observations on colony morphology showed 7 rhizosphere bacterial, genus observed as Bacillus sp. and that besides it was not identified. Research showed that the bacteria could potentially control the banana root disease caused by Fusarium.

ABSTRACT The research was conducted at fresh water swamp, tidal swamp and irrigated Rice field.Fresh water swamp and Tidal swamp located countryside Betung, subdistrict Pulau Rimau and Sako, subdistrict Rambutan, Regency Musi Banyuasin. While irrigated lowland rice countryside at 0mangunhardjo, Subdistrict Purwodadi, Regency Musi Rawas, from June through October 2010. The research was aimed to knowing and comprehend or understand with to decreased fluxe and emission methane produced and compared with three ecosystem lands cultivated S.R.I. The split plot design was appllied in the research. The treatment main plot consisted of lowland rice (T) with three factors: fresh water swamp (T1), Tidal swamp (T2) dan Irrigated rice field ( T3) and sub plot cultivated (S) there were two factors: convensional (K) and S.R.I (S). The result showed that the rice cultivated S.R.I can decreased of flux methane 40-71% and in the form of emission of gas metan one growing season plant may decrease 19-53 %. Being emang three ecosystem may decrease 61-66 %. Measurement of methane gases emission for the three ecosystem rice field to each other every a period of growth showed the declaned at the age 8 week after planting. Later then the total emission of methane increased before harvest. Key Word: Convensional, Flux and Emission, Fresh Water Swamp, Methane, SRI, Tidal swamp.
