The aim of this experiment was to determine the effect of the addition of ash and sand-compost proportion in the media on the growth of sorghum (Sorghum bicolor L.). Theexperiment was conducted on December 2015 to January 2016 in the Botanical Laboratory,Biology Department, Faculty of Mathematic and Natural Science, Lampung University, andwas conducted in a complete randomized design by using two treatments. The first treatmentwas the addition of ash in two equivalents (with and without ash), the second treatment wasthe addition of sand-compost proportion in four equivalents (2 kg of sand, 1Â¾ kg of sand +Â¼ kg of compost, 1Â½ kg of sand + Â½ kg of compost, 1Â¼ kg of sand + Â¾ kg of compost). Theobserved variables of the growth were the number of the roots, the crownâ€™s length, the wetweight, and the dry weight. The number of the roots was determined by observing thenumber of the roots present at the base of the stalk of each plants. The length of the crown(cm) was determined by measuring it from the stalkâ€™s base to the edge of the longest leaf.The wet weight (g) was determined by measuring the whole part of the plant using ananalytical balance. The dry weight (g) was measured after the plants were stored in an ovenfor three hours in the temperature of 70o-80oC. The result showed that the best growth wasobtained from the media with the sand equivalent of 1Â¼ kg of sand added with Â¾ kg ofcompost without ash.Key words: Ash, compost, growth of sorghum (Sorghum bicolor L.), sand

The research was conducted in February to June 2015 in the District of Rajabasa Raya, Bandar Lampung. Research used design of randomized perfect group design with five dosages of compound NPK fertilizer (16:16:16), i.e., 0, 25, 50, 75 and 100 kg/ha applied at R1 (early Flowering) and repeated three times. Homogeneity was tested with Bartlet and the addition data was tested with Tukey, and analysis of kind (if applicable). Mean separation test used orthogonal polynomial on the level of confident 5%. The results showed that application of compound fertilizer NPK 16:16:16 increases soybean yield (t/ha) and nutrient efficiency. However, NPK applications have no effect on plant height, plant dry weight, number of total branches, number of productive branches, total number of pods, and weight of 100 grains of soybean seeds. Dosing up to 100 kg/ha of NPK compound increase soybean yield but still shows a linear graph Keywords: soybean, early flowering (R1), NPK fertilizer, NPK dose.

This research was conducted to determine the effect of crude fiber level in rations of gizard weight, length and weight of small intestine, caecum, colon drake. Research using a completely randomized design consisting of four treatment levels of crude fiber (5, 10, 15, and 20%) and repeated four times. Data analysis of variance test results and continue testing the average value with Duncan Multiple Range Test. Ducks 3 weeks old experiment as much as 64 tail is divided into four treatments and each treatment consisted of four ducks. All treatments formulated rations containing protein (16%) and ME (2600 kcal/kg) is the same. The main source of crude fiber in the diet is fine bran. The results showed significantly different levels of crude fiber (P <0.05) to the length of small intestine drake. Keywords: Ducks male, Fiber, Carcas, Visceral Organ.

Hybrid corn is a first generation (F1) from the cross between two or more inbred line. Hybrid maize seed produced in Indonesia by BISI, PT.Du Pont Indonesia, and Syngentha. Inbred line as seed imported from abroad. In Indonesia the company only produce F1 hybrid seed corn. The problem for Indonesia is a very large dependency needs seed hybrid corn to foreign countries.Polinela current tread olready up 13 single-cross maize hybrid with inbred line the assembly itself in Polinela. Research aims to find the groove single cross corn hybrids that have superior characters in the quality and quantity.Research conducted in Polinela, Maret 2009 until July 2009. Research conducted with Randomize Completly Block Design (RCBD) as the treatment were 13 single cross maize hybrid assembly Polinela. Use as a benchmark Pioneer 23 (P-23), all treatment repeated three times. To know the differences between the treatment then continued with Least Significant Different (LSD) on stage 5%. Results of the research potential of 13 single cross hybrid there are (1) Generally assembly Polinela hybrid have caracteristics not significant rather than P-23, (2) Two assembly Polinela hybrid that has the potential of higher than P-23, that is hybrid C (PL. 401xPL. 201) and Hybrid K (PL. 20xPL.401).

The use of ferns as orchid growing media feel expensive, so it is necessary to find an alternative media as a media surrogate fern that has been used. This study aimed to explore alternative growing media and fertilizer is good for growth and development of dendrobium orchids. Selection of a good planting medium and the proper use of fertilizers can be expected to support healthy plant growth and quality of orchids. experiments were conducted at Greenhouse Faculty of Agriculture Lampung University. The experiment was conducted using a randomized design perfectly with the treatment group factorial (6x2). The first factor is the type of growing medium consists of wood charcoal (M1), fern (M2), husk + sawdust (M3), acacia bark (M4), cocochip (M5) and coconut bark (M6). The second factor is the type of foliar fertilizer consists of Gandasil (P1) and Hyponex (P2). Data were analyzed by analysis of variance followed by HSD test at 5% level. The results showed that the use of media orchids ferns produce good vegetative growth, no different to use of planting medium charcoal, charcoal husk + sawdust, bark and bark acacia tree coconut, but it is different than the use of cocochip shown in variable plant height, number of leaves , leaf length and leaf width. While fertilizers orchid leaves that produce good growth is fertilizer of Gandasil

The research of labor forces in village has never been released to national development strategic. So that, the amount of labor forces absurption must be solved wiht oppening job opportunity outside agriculture sector. This reseach gave information of labor force in agriculture sector and village on dry land basis. This research showed that job participation an unemployment level, nationally. Didnâ€™t change.In horticulture dry land basis, the role of agriculture sectors were still dominated job opportunity than outside agriculture. Nevertheles, hosehold job opportunity in the village has a lot of variety and replaced the the role of job opportunity in agruculture sectors. In the other hand, work group of in agriculture sector was more dominated with lower education from down elememtary school and it could not complete in labor force market outside agriculture sector. So, that, the role of agriculture sectors was still improtant to solve labor force problem in villages and still become a burden if itâ€™s not balanced with labor absorption in outside agriculture sector.

This research was conducted to determine the effect of crude fiber level in rations to feed consumption, body weight, body weight gain, carcass weight, breast weight and thigh weights male duck. Male ducks 3 weeks old were divided into four treatments, each treatment ration is repeated four times using four ducks each replication. Ration of treatment given to duck experiment with the level of crude fiber 5, 10, 15, and 20%. Treatment rations containing protein (16%) and ME (2600 kcal/kg). The main source of crude fiber in the diet is fine bran. Data were analyzed using completely randomized design direction, then the test with Duncan Multiple Range Test. The level of crude fiber significantly affect (P<0.05) on average feed intake, body weight, body weight gain, carcass weight and breast weight male duck. Keywords: Male ducks, Crude fiber, Carcas
