Efficiency of water usage is needed for sustainable agriculture. The aim of this research is to investigate the hydroponic (NFT, DFT, Aeroponic) efficiency on water use using Amaranthus viridis L. as the planted material. Efficiency on water use was measured by comparing the water use on hydroponic with the control during the plant growing period. The result shows that the three type of hydroponics are able to increase efficiency of water use. NFT is the most efficient technique with efficiency on water use 20.43%. While DFT and Aeroponic, has the efficiency on water use 12.29% and 3.57%, respectively. Enhancing efficiency of water use on hydroponic was caused by the clossing and circulating irrigation technique on hydroponic are able to minimize the evaporation .

ABSTRACT
Species diversity and distribution of butterflies (Lepidoptera; Rhopalocera) of the urban forest of Muhammad Sabki, Jambi were studied from January to February 2012. The urban forest was divided into four different habitat types: the Park, the Stream side, the Rubber forest, and the Mixed forest. Two transect routes were established for each habitat type. Observations were made on the number of individuals of each species of butterflies found within the transects. Data were analyzed by Shannon-Wiener, Evenness, and Sorenson indices. A total of 43 species with 3241 individuals of six families (Hesperiidae, Papilionidae, Nymphalidae, Lycaenidae, and Riodinidae) of butterflies were recorded. Nymphalidae was the most dominating family with the highest species richness at the urban forest. The highest number of butterfly species was recorded at the Rubber forest and the Stream side (37 species each), followed by the Park (33 species) and the Mixed forest (27 species). The most abundant butterflies were found at the Rubber Forest, and the least were in the Stream side. Two species (Eurema hecabe and Mycalesis janardana) were observed consistently at all habitat types, and the former was the most abundant species. The highest species diversity and evenness indices were found in the Rubber Forest, while the lowest were in the Stream Side. Species diversity and evennes indices of butterflies of the urban forest can be categorized as low and low to moderate respectively. Based on their similarity indices of species (IS), the community of butterfly of the urban forest consisted of three communities: the Park, the Stream Side-Rubber Forest, and the Mixed Forest. The highest IS was found in the Stream Side- Rubber Forest. Nevertheless, high similarity indices (>0.7) of the butterflies between communities indicating that the communities of the butterfly had almost similar species composition, and most species were widely distributed across all habitat types of the urban forest.

Strain DDY after Laser Assisted HatchingThe research aimed to find out whether 5 , 10 , and 15 concentration of Ethylene glycol EG and Dimethyl sulfoxide DMSO in vitrification can influence the development of early blastocyst culture of mice Mus musculus L. strain DDY after Laser assisted hatching LAH and to determine the best concentration of EG and DMSO in vitrification. The test embryos used were early blastocysts from superovulated mice after mating with adult male. Early blastocyst stage of embryo was performed LAH with 1 2 thinning around the zona pellucida. The test embryos were divided into five groups with six repetitions, namely KK 1, KK 2, KP 1, KP 2, and KP 3. KK 1 is early blastocyst after LAH then cultured, whereas KK 2 is early blastocyst in vitrification and then cultured. Then, KP 1, KP 2, and KP 3 are early blastocysts after LAH then vitrification on EG and DMSO with concentrations of 5 , 10 , and 15 , and then cultured. Based on result, the average percentage of embryo viability, hatched embryo, and degeneration respectively in KK 1 is 75.00 23.33 25.00 , KK 2 is 58.33 11.67 41.67 , KP 1 is 51.67 6.67 48.33 , KP 2 is 70.00 18.33 30,00 , and KP 3 is 75.00 23.33 25.00 . Based on LSD test, EG and DMSO concentrations affect the embryo development after LAH in vitrification. KP 3 is early blastocysts after LAH that were in vitrification by EG 15 DMSO 15 0.5 M sucrose is the best concentration in vitrification of early blastocyst culture after LAH.

Penelitian dilakukan untuk mengetahui potensi nefroprotektif dimer isoeugenol terhadap histologi ginjal mencit jantan galur DDY. Tiga puluh ekor mencit jantan dibagi secara acak dalam enam kelompok, yang terdiri atas kelompok kontrol normal, kelompok kontrol kerusakan, dan kelompok perlakuan. Kelompok kontrol dicekok dengan minyak zaitun selama 7 hari berturut-turut. Kelompok perlakuan dicekok dengan larutan dimer isoeugenol dosis 2, 4, 6, dan 8 mg/kg bb selama 7 hari berturut-turut. Kelompok kontrol kerusakan dan kelompok perlakuan diinjeksi intraperitoneal dengan karbon tetraklorida dua jam setelah pemberian dosis hari ke-7. Ginjal diamati secara makroskopik dan mikroskopik. Uji statistik menunjukkan terdapat pengaruh nefroprotektif dimer isoeugenol terhadap rata-rata diameter kapsula Bowman, diameter glomerulus, dan jumlah tubulus proksimal yang menutup, namun tidak terdapat pengaruh terhadap ratarata diameter ruang Bowman dan berat basah ginjal. Hasil penelitian menunjukkan setiap dosis perlakuan dimer isoeugenol memiliki pengaruh nefroprotektif. Dimer isoeugenol dosis 4 mg/kg bb menunjukkan pengaruh paling baik. ......This research was designed to investigate the nephroprotective potential of isoeugenol dimer on DDY strain male mice kidney histology. The animals were divided randomly into six groups, consisted of normal control group, injury control group, and treatment groups. Control groups were administered olive oil orally for 7 consecutive days. Treatment groups were administered doses of isoeugenol dimer solution 2, 4, 6, and 8 mg/kg w/v orally for 7 consecutive days. Injury control group and treatment groups was induced by intraperitoneal administration of carbon tetrachloride 2 hours after the 7th dose. Kidneys were observed in macroscopic and microscopic. Statistic study showed that there was a nephroprotective effect of isoeugenol dimer against the average diameter of Bowman's capsule, diameter of glomerulus, and total complete obliteration proximal tubule lumen, but no effect was found on the average diameter Bowman's space and kidney weight. The result showed that each dose of isoeugenol dimer has a nephroprotective effect. Isoeugenol dimer dose 4 mg/kg w/v has the best effect.
