This research aimed to study the influence of inorganic and organic manure combination rate on peanut crop yield and growth. The experiment applied randomized block design which was arranged as factorial. The first factor was rate of farmyard manure and the second factor was rate NPK fertilizer. Data were collected through measurements of plant high, number of branch, number of leaves, plant biomass weight, heavy and wet heavy run dry polong, number of polong and heavy 100 dry seed. The results showed that there are real interaction between treatment of organic manure and inorganic manure to component of vegetative and generative except plant biomass weight. combination farmyard manure 1 kg /plot and NPK fertilize 20 g /plot (A1N1) represent optimum dose at peanut crop conducting posed at by variable is number of polong equal to 21.07 polong, weight of polong equal to 63.16 g, dry weight of polong equal to 37.74 g and 100 dry seed equal to 47.79 g/ plant

Research using potential local leguminosa to used supplementation with basal diet rice straw to effort effects on intake, nutrient digestibility and daily gain sheep. Research materials consisted of 16 rams, average body weight 13,10 ± 0,4 kg, placed in 16 individual cages. Treatment of feed used are rice straw, Gliricidia maculata and Leucaena leucocephala. Research methods in vivo experiments with randomized block design (RBD), which consists of 4 treatments and 4 replications. The treatment consisted of level legume supplementation on R0 (0%), R1 (0.25%), R2 (0.5%), and R3 (1.0%). The results legume supplementation on basal diet of rice straw showed very significant on feed intake, digestibility and intake digested of feed (P0.05). Conclution in this research: supplemented legume Gliricidia maculata and Leucaena leucocephala 1.0% BW on basal diet rice straw shows feed intake, digestibility and daily gain tend to give better performance

Seaweed in Wuakerong Village, Nagawutung Sub District, Lembata Regency has prospects and business opportunities are adequate to give hope to farmers in improving welfare. The fact that seaweed farming has not yet provided better and maximum results as desired by the farmers. This study aims to evaluation the marketing channels, marketing margins and profit share of marketing agencies. The research is located in Wuakerong Village, Nagawutung Sub District, Lembata Regency which is determined purposively. The number of sample is 30 farmers taken by simple random sampling, 4 middlemen traders and 2 gatherer traders taken by using snowball method. The data collection methods is interview and questionnaire directly to farmers and marketing agencies, literary method or data collecting from institutions related to the research’s aims. The variables observed covered the condition of location, population, level of education, land, production, sale price, purchase price, marketing margin, profit share of marketing agencies, and marketing margins distribution. The research results show that there is two marketing channel in the researched result, as follows: Channel I : farmers middlemen traders gatherer traders PAP Channel II : farmers gatherer traders PAP The magnitude of marketing margins is different between the marketing channels, and so it is with profit share of marketing agency. On channel I, magnitude margin is IDR 3,250 and profit share is 71.11% on farmers, 17.76% on middlemen and 11.09% on gatherer traders. On channel II, the magnitude of marketing margin is IDR 1,250 and profit share is 88.88% on farmers and 11.09% to gatherer traders

FERMENTASI BLOTONG LIMBAH PG. KREBET DAN RUMEN SAPI DALAM PRODUKSI BIOGAS Pramono Sasongko; Lorine Tantalu
BUANA SAINS Vol 18, No 2 (2018)
Publisher : Universitas Tribhuwana Tunggadewi

Sugar Cane Filter Cake (SGFC) is the sugar cane to sugar processing waste in Krebet Baru Sugar Factory. Utilization of this SGFC waste was limited for free soil or unprocessed fertilizer. Sugar cane filter cake is an organic waste which potential to be utilized into biogas. Biogas is anaerobic process product which consist methane as a major compound. Factors that influence biogas fermentation process were temperature, water content, fiber, total sugar and total concentration of methanogen bacteria inoculum. Natural source of methanogenic bacteria is in the contents of the cattle rumen. The aim of this study was to determine the characteristics of blotong and the effect of addition of cattle rumen on biogas fermentation from the SGFC of the Krebet Sugar Factory. The first stage of this research was Blotong characterization. The second stage was spontaneous fermentation with two treatment factors. The first factor was enhancing the contents of the cattle rumen (5%) and without the addition of cattle rumen (0%). The second factor is the fermentation time with 3 different levels (20, 25 and 30 days). The results were shown that blotong had water content, fiber content, and C / N ratio were 10.71%; 0.06%; and 17: , respectively. These results indicate the potential of the blotong as a raw material for biogas production. SGFC fermentation with the addition of 5% cattle rumen content was shown the best results compared to biogas production with pure SGFC. The highest volume and yield of biogas produced were obtained from the 30-day fermentation process with the results of 37,327 ml of gas and 746.5 x 10-6 m3/kg. All flame tests show positive results and are proven to produce blue flames.

Sedap malam (Polianthes tuberose L) is cut flower, broadcast flower and natural oil crop. The aims of this research is to increased quality and productivity of flowers. Field experiment was conducted during Februari to September 2008 in polibag and Factorial Randomized Block Design was applied with three (3) replications. The treatment consist of 4 level of colchicines concentration (0, 100, 200 and 300 ppm) and 3 level length of inundation (3, 6 and 9 hour). The result showed that there is an interaction between concentration and length of inundation on length of flower stalk, size of flower and time of harvest. Application of 100 ppm and 3 hour inundation made longer stalk of flower but become shorter when continue inundation up to 9 hour. Size of flower increased with increased concentration and inundation, but colchicine did not affected number of flowers

This study was aimed to explore of plant affectivity in using its environmental resources and to quantitatively solve problems related to growth of sweet corn. Twelve treatments comprising four levels of rice straw application and three levels of nutrient application was arranged in a randomized block design with three replicates. The results showed that a combination of 10 t rice straw/ha with 400 kg Urea, 35 kg TSP, and 250 kg KCl /ha produced the highest stem dry weight. There was no interaction between leaf dry weight, root dry weight and cop dry weight of the plant

Ozone is one of the constituent gases of the atmosphere. This gas is concentrated in the stratosphere layer functions as a UV filter so as not to cause damage on the surface of the earth. This layer of ozone in most produced by the reaction of oxygen with ultraviolet light. Ozone in the troposphere is the layer of air pollutants and harmful to the respiratory system of human, animal and plant metabolism. The presence of ozone in Earth's atmosphere in low concentrations throughout the year. Decreased concentration or the ozone layer depletion triggered by the compounds of CFCs (Chloro Fluoro Carbon) and ODS (Ozone depleting Subsantance). ODS compounds include nitrogen oxide (N2O) is a byproduct of combustion, methyl bromide, carbon tetrachlorida and methyl chloroform. To determine the thickness of the ozone layer is measured by satellite instruments or Nimbus-7 satellite instruments EP-toms. Total concentration of atmospheric ozone standard can be determined using the unit DU (Dobson Unit). Concentration at a point can also be measured in units of ppb (parts per billion) or in μg.m³. Efforts to reduce ozone layer depletion, among others, regularly measure the thickness of the ozone, suppress the use of CFC compounds that are widely used as refrigrant in freezers, refrigerators, room air conditioning and engine cooling, spray cans for air freshener, perfumes, solvents, foam developers and reduce the use of ODS substances which have been agreed by the international community through the Montreal Protocol, Canada in 1987
