The prominent purpose this experiment was producing superior quality of Carasius auratus, which is have to growth faster and good morphology. While particular purpose was to know temperature level effect on triploidisation on individual triploid (3n) formation of Carasius auratus and to find suitable spawning method /combination in Carasius auratus propagation but settle make high productivity. Spawning was conducted using induce breeding. Carasius auratus was spawn with support by hormone stimulation. Triploidisation was using heat shock to achieve triploid fish (3n). The same procedure was conducted to control. Heat shock temperature level was 40, 41 and 42oC. Result of this experiment showed that fish on heat shock 40oC given individual triploid presentation high more than fish on heat shock 41 and 42o C. Where as control was 100% of individual diploid. Hatching and larvae survival rate were shown value lower than control without heat shock. Keywords: Carasius auratus, quality, triploidisation

Secang drink is an Indonesia tradisional drink (from Yogyakarta dan Central Java) there tare made from secang wood (Caesalpia sappan L). In secang drink, we can found another spices, like ginger, clove, sereh, cinnamon bark, kapulaga, and pala. Empirically, the function of secang drink is to take care health, because their bioctive component. The main bioactive component of spices are fenol compound. The fenol compoud can measured with Follin Ciocalteau method. The advantage of Follin Ciocalteau method is give same response to different fenol compound. While the disadvantage is give response to sulfur dioxide and sugar. Except spices, in secang drink contain sugar and salt too, that function to give a delicious taste. The purpose of research is to know the effect of sugar to amount of fenol compoud in secang drink. The amount of fenol compound in secang drink with sugar are 117,972 ? 186,055 mg/L. While without sugar are 16,778 ? 91,528 mg/L. The incresing of amount of fenol compound in secang drink with sugar because Follin Ciocalteau method to consider sugar is a interference that can give unreal amount of fenol compount. Keywords: sucrose, fenol content, secang drink

The main obstacle in breeding cassava plant is a flowering plant age which is not the same between the genotypes and the long time needed for a breeder to get cassava flowering before it is crossed. The purpose of this study was to determine the application of various concentrations of Paclobutrazol through the leaves of cassava plants to induce early flowering in the lowlands. Plant materials in the form of cuttings were taken with the size of 25 cm in length. The clone used was called Thailand taken from the field 10-12 months after planting. This experiment was conducted with complete randomized block design. Each treatment was repeated three times and each experimental unit consists of at least two-plant samples. Paclobutrazol treatment consisted of a wide range of concentration. Those were: 0 (P0), 250 (P1), 500 (P2), 750 (P3), and 1000 (P4) ppm. Paclobutrazol was sprayed through the leaves and carried out on plants that have been 30 days after planting with a volume of 100 ml per crop. The application through the soil was also done once while through the leaf was done 3 times with 1 week interval, each application was given with a volume of 20 ml, 30 ml and 50 ml. The results showed that Paclobutrazol Application of 500 ppm through the leaf was s the best concentration in stimulating the formation of branches and flowers compared with other Paclobutrazol concentrations Keywords: Paclobutrazol, Cassava Plant, Early Flowering, Lowland

Quality factors intensively noticed by consumers are bean color, bean maturity, length of bean, bean shape, shape of bean surface, bean crispiness, and sweetness of bean.Since, potassium fertilization could increased the quantity and quality of yield some crops.The objectives of this research were to know the characters of production and young bean sweetness in different potassium environments. The treatments were arranged in factorial arrangement (2x4) with 3 replications. First factors were genotype of long bean which were stripped seed (G1) and black seed (G2). Second factors were KCl dosages which were 0 kg.ha-1(K0), 50 kg.ha-1(K1), 100 kg.ha-1(K2), 150 kg.ha-1(K3) dan 200 kg.ha-1(K4). The genotype of stripped seed had superior quality of production, while yield quantity didn tdifferent between genotype. Fertilization of potassium with dosage 50 kg of KCl /ha had increased the quality of yardlong bean crop production. Keywords: Sugar Content Pod , Peanut Genotypes, Potassium Fertilization

Nurman Abdul Hakim: Perbedaan Kualitas dan Pertumbuhan Benih Edamame Varietas Ryoko? Volume 13, Nomor 1, Januari 2013 9 1, 2, and 3 weeks, it is seen that the seeds produced in the Highlands of generating plant weights heavier than seed produced in the lowlands. Keywords: : seeds edamame, altitude place, seed qualityThis research aims to know the difference in the quality of the seeds and the growth of the edamame is augmented at an altitude of different places. In addition, to find out whether the height effect on physiological properties of the seed varieties edamame Ryoko. Planting edamame made in May ? August 2012 simultaneously in two locations: in the Highlands (West Lampung, Sekincau) and in the lowlands (the practice of lampung State Polytechnic). Edamame seeds that are produced in both places are then tested in the laboratory of food crops. and in Lampung State Polytechnic. Seed quality testing is done using the complete randomized design and is repeated 5 times. The observations showed that seed produced in the Highlands (West Lampung, Sekincau) looks greener than seed produced in the lowlands (Lampung State of Polytechnic). When compared on the basis of the size of the seed, then it looks also that seed produced in the Highlands, are smaller. Weight of 100 seeds of grain produced in the Highlands of lighter (26.8 g) than the seed resulting from the lowlands (36.4 g). The test results obtained through the analysis of statistics that the percentage of seed sprouts power resulting from the planting in high places better (79%) than from planting in lowlands (73.2%). Look also that the seed resulting from the planting of high-yield abnormal smaller sprouts (16%) than are generated in a low place (22.4%). The results of testing the levels of protein and fat which is done in the laboratory of Agricultural Technology Lampung State Polytechnic obtained that protein levels are the second seeds at the height of the place is no different, which is around 36%. While the fat content of seeds produced in the Highlands of 13.8%, lower than the seeds that are produced in the lowlands which amounted to 15.8%. The observations of plant height at the age of 1, 2, and 3 weeks, looks that seed produced on the highlands produces plant growth higher than seed produced in the lowlands. The results of observation of the number of leaves of plants at the age of 1, 2, and 3 weeks, it looks that the seed resulting in the Highlands and the lowlands produced the same number of leaves on the plant young edamame. Result observation of plant age on edamame weights of

The duration of submersion and the level of acid concentration which are the decisive factors to succed the chemical scarification. The duration of submersion should be adjusted to the level of seed skin thickness, the level of acid concentration and the type of acid used. This study aimed to analyze the inmersion effect of kemiri sunan seeds in sulfuric acid solution to break the seed dormancy and to get the most effective time of submersion in order to break the dormancy of kemiri sunan seed. The experiment was conducted in the greenhouse for 2 months (62 days). The randomized complete design was employed as experimental method. There were 4 treament tested, i.e : (1) control (without immersion in H2SO4 solution); (2) immersion in H2SO4 solution for 10 minutes; (3) immersion in H2SO4 solution for 20 minutes and (4) immersion in H2SO4 solution for 30 minutes. The results of research showed that control gave the best results in term of the percentage of germination (G), mean daily gremination (MDG), and germination rate (GR).
