The aim of this research is to determine character for drought tolerance character prediction of peanut national variety on germination phase using PEG 6000 solution. Preliminary test using drought tolerance genotipes (US 605 and US 693), susceptible genotipe (PI 409) conducted to evaluate appropriate concentration of PEG solution as drought treatment. PEG 10% is appropriate for drought treatment. Experiment using factorial random complete design with eight national varieties, Badak, Gajah, Jerapah, Kelinci, Komodo, Macan, Panther, Singa, and PEG solution. Minimum water uptake for germination is obtained from proportion between seedling weight to seed weight with seed weight. Root length, number of lateral root and seedling dry weight (without cotyledon) are counted on seventh day after germination. Seed germinated using UKDdp method. ANOVA two way for water uptake variable, ANOVA one way for root length and number of lateral root and seedling dry weight (without cotyledon) is used to analyze data, continue with DMRT and Pearson product moment correlation between minimum water uptake for germination and root length, seedling dry weight (without cotyledon). And Spearman correlation is used between minimum water uptakes for germination with number of lateral root. The results base on this research are, drought tolerance characterization of peanut national variety could evaluate on germination phase simulated by 10% PEG 6000 solution. (2) Minimum water uptake for peanut seed germination could be use as determine character to drought (3) Base on minimum water uptake for germination, Gajah and Panther grouped as drought tolerance varieties, Macan, Jerapah, Singa and Badak as medium tolerance varieties, and Komodo and kelinci as susceptible varieties.(4) In peanut, root length, number of lateral root and seedling dry weight (without cotyledon) can not be use as determine character to drought on germination phase.

The idat plant is one of the endemic plants known to the people of bangka belitung as well the shoot of idat (Cratoxylum glaucum). Cratoxylum glaucum is widely used as a traditional the skin, treat diarrhea, as antibacterial, anticancer,antivirus, and other diseases. Based on the potential of activity,the development of an Cratoxylum glaucum extract in the from of nanoemulsi is carried out which has stability and a small droplet size so that it isvery effective as an antibacterial. The purpose of this study was determine how the characterization and antibacterial activity of nanoemulsion from the Cratoxylum glaucum. Nanoemulsion was made using a homogenizer at a stirring speed of 8000 rpm for 30 minutes with a composition of 2,5 ml VCO, 10 ml tween 80, and 37,5 ml water. Nanoemulsion fraction MeOH : water from the shoot idat has a droplet size of 101,6 nm with a PI value of 0,274 and has a transmittance percent of 80,33% which can be categorized as a nanoemulsion with good stability compared to ethyl acetate and n-hexane nanoemulsion. In addition, nanoemulsion MeOH : water an antibacterial activity of S. Aureus by 10,42 cm which is categorized as strong.

AbstractThis study aims to determine the science literacy ability of students based on teacher’s literacy abilities in cities and villages. The science literacy ability of students and teachers both in cities and villages were measured using two different types of test instruments each for teachers and students consisting of 40 modified PISA and TIMSS questions. The method used in this research is Ex-Post Facto. The study population were three schools in the village and three schools in the city chosen by purposive sampling based on the high, medium and low national examination (UN) scores, with the total number of research subjects of 480 students and 16 teachers taken at randomly. Data analysis was made using ANAVA test. The results showed: 1) there is an influence of the geographic location of the school in the village and in the city against students science literacy with p <0.00; 2) there is no effect of UN score on science literacy score of students with p> 0.189; 3) there is no influence of teachers science literacy on students science literacy with p> 0,318; 4) there is an influence of geographical location in city and in village with UN input to students science literacy with P <0,00; 5) there is no influence of geographical location with teachers literacy toward students science literacy score p> 0,194; 6) there is an influence of UN score input with teachers science literacy on science literacy score of students with P <0.00; 7) there is no influence of geographical location, UN value and teachers literacy toward science literacy score of students with P> 0.712.

Foxtail millet is high nutritional minor cereal potentially for food diversification. The cultivation expected can be expanded to other marginal areas, such as shading areas in the garden or yard. The research aimed to study the response of foxtail millet growth and production at various shading intensities and fertilization. The experimnental design was a RCBD with two factors. The first factor was shading intensity (0. 25, 50, and 75%), while the second was NPK fertilization (0, 2, and 4 g/pot). The variable observed were vegetative phased, generative, chlorophyll content (CC), and leaf area ratio (LAR). The results showed that shading intensity had a significant effect on all variables observed. The highest plant growth and production achieved at 0% shading intensity (total panicle dry weight 12.31g/plant). The highest both of CC (3.25 SPAD) and LAR were on 75% shading (263.17). Fertilization has no significant effect on the growth and production. There was an interaction between shading treatment and fertilization on chlorophyll b content, and the highest was on the combination of 50% shading and 2g/pot (1.04 mg/g) fertilization. The optimum growth and production achieved at 0% shade. The total panicle dry weight decreased with increasing shade, but at 25% shade, the percentage decreased < 50% (44.27%). It is expected that foxtail millet can be cultivated in areas up to 25% shading intensity.
