Judul: Efektivitas Pupuk Daun Growmore 6-10-40 Terhadap Pertumbuhan, Produksi Dan Kadar Hara Tanaman Jagung (Zea mays. L) Pada Tanah Latosol Darmaga
Abstrak: One of the methods in using fertilizer is the use of fertilizer on the leave, commonly known as a foliar fertilization. Absorption of nutrient elements which is sprayed on the leave is conducted by stomata and cuticle. Foliar fertilization leave is relatively more efficient compared with fertilizing through roots. The nutrient absorption on leaf is faster than those at the roots. So crop growth is better and may reduced soil degradation. The objective of this research was to study the effectiveness of foliar fertilizer of Growmore 6-10-40 on the growth, production and nutrient content of corn plant (Zea Mays L. ) in Latosol Dannaga and economic feasibility. The design of the research was randomized completely block design (RCBD) with one factor and three replication. The factor consists of 10 treatments i.e. 1) control (without fertilizer); 2) SI (200 Kg Urea, 100 Kg SP~36, and 37,5 Kg KCl per hectare) Gl; (3,5 Kg Growmore per hectare); 3) SlG2 (7 Kg Growmore per hectare); 4) SlG3 (10 Kg Growmore per hectare); 5) S1G4 (14 Kg Growmore per hectare); 6) S2 (250 Kg Urea, 150 Kg SP-36, 75 Kg KCI per hectare) Gl; 7) S2G2; 8) S2G3; 9) S2G4; and 10) Standard! Standard Fertilizer's dosage (300 Kg Urea, 200 Kg SP-36, 150 Kg KCI per hectare) The result of this research indicated that generally application of foliar fertilizer of Growmore 6-10-40 significantly increase variables of the nitrogen content of corn leaf, diameter and length of corn, weight of 100 seeds of corn, weight of fresh grain and seed of corn The Highest RAE grade occurred at standard treatment (100 %) while on Growmore 6-10-40 treatment, the highest RAE occurred at S2G4 treatment (97,6%), followed by S1G3 (93,8%), SlG4 (92,68%), S2G2 (82,25%), S2Gl (81,12%), S2G3 (70,14%), S1G1 (67,04%) and SlG2 (66,20%). Based on the economically feasibility using Revenue/Cost Ratio, all of treatments were able to be recommended, except treatment of control. The highest RIC ratio was belonging to S1G3 treatment (1,63). Thereafter, based on the computation of optimwn rate, the optimum rate of Growmore 6-10-40 was 1,95 gil and its equal 6,26 Kg per hectare.

Judul: Uji efektivitas pupuk daun growmore 32-10-10 terhadap pertumbuhan, produksi, dan kadar hara tanaman jagung di tanah latosol Darmaga (Oxic Dystropept)
Abstrak: Corn is important food commodity beside rice. The productivity of corn in year of 2005 was 12.52 million tons increased by 1.30 million tons compared to corn productivity in year of 2004. One of methods to increase the productivity is by using fertilizer. Effectiveness fertilize is to add mineral nutrients which are slightly supplied so it can use by the crop optimize. Foliar fertilizer is an artificial fertilizer which given to the crop by mean of spray to the leaf. Generally foliar fertilizer consist of macronutriens such as N, P, K, Ca, and Mg and micronutrients such as Fe, Cu, Co, Mn, and Zn. The main purpose of this research is to observe the effectivity of Growmore 32-10-10 foliar fertilizer compare to standard fertilization on corn crop. The research use randomized complete block design. The treatment consisted of : (1) Control (2) Standar (recommendation fertilization of Indonesian Agricultural Departement) (3) S1G1 (4) S1G2 (5) S1G3 (6) S1G4 (7) S2G1 (8) S2G2 (9) S2G3 (10) S2G4. all of the treatments repeated by three times in block. S1 equal to ¼ standard dose and S2 was equal to ½ standard dose. These doses were combined with Growmore (G1, G2, G3, and G4).

Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
