The Effect of Bio Liquid Fertilizer Application on the Growth and Yield of Two Varieties of Maize (Zea Mays L.)

The research was conducted at the experimental field of Assessment Institute for Agricultural Technology (BPTP) Lampineung Banda Aceh. The experimental arranged in a randomized complate block design in a factorial design with three replications. Bio liquid fertilizer Ultra Gen consisted of four levels, i.e. without liquid fertilizer (P0), 0,8 liter ha-1 (P1), 1,7 liter ha-1 (P2), and 2,5 liter ha-1 (P3). Varieties consisted of two levels, i.e. Pertiwi (V1) and Local Aceh (V2). Parameters observed in this research were plant height and number of leaves aged 15, 30, and 45 days after planting, corn length with cornhusk and without cornhusk, corn diameter with cornhusk and without cornhusk, corn weight with cornhusk and without cornhusk, weight of 100 grain dry seeds, shelled seeds weight dry per plant and yield. The result showed that concentration of 0.8 liter ha-1 gives better results compared to concentrations of other bio liquid fertilizer Ultra Gen, and Local Aceh variety of maize crop is better compared to Pertiwi variet

Karakterisasi Mekanik Biokomposit Klobot Jagung sebagai Bahan Dasar Plastik Biodegradable

The corn production in Indonesia, based on the data from Badan Pusat Statistik in 2012, amounted to 19.73 million tons, the cornhusk from the corn crop is about 38.38%. The utilization of cornhusk itself has not been maximized yet, so the research to maximize the utilization of cornhusk is required. The research has been made biocomposites cornhusk and Linear Low Density Polyethylene (LLDPE) with hot press method. Biocomposites made with the variation of cornhusk:LLDPE are 30:70, 40:60, 50:50, 60:40, 70:30, and it is characterized of the mechanical characteristics (tensile and tear) with Universal Testing Machine (UTM), biodegradation in a qualitative manner. Mechanical analysis showed the mechanical characteristics decrease with the addition of cornhusk concentration on biocomposites, and concentration 30:70 has the highest mechanical characteristics with tensile strength 24.77 MPa, elongation 19.10% and tear strength 53.94 N/mm. The result is contrast with the biodegradable analysis in which the bigger concentration cornhusk then the level of biodegradability is higher

New Mixture Additives for Sustainable Bituminous Pavements

In an effort to improve mechanical properties of asphalt concrete, an exploratory research using mixture additives was attempted. Two different types of additives on two material scales were used: asphalt concrete (AC) level and binder level. At the start of this study, the effect of natural cornhusk fibers on the resistance of two types of AC mixtures on cracking were tested for hot-mix asphalt (HMA) and cold-mix asphalt (CMA). The results showed slight improvements in cracking resistance in cornhusk reinforced HMA, and in the case of the CMA, marshal flow. Overall, based on the test results, cornhusk-reinforced HMA and CMA may not significantly improve critical mechanical properties given the added cost of fibers. In addition, cornhusk fibers proved difficult to properly disperse in HMA and CMA when mixed in laboratory. However, when fibers were mixed in an asphalt production plant, the fibers appeared to become more distributed. The second part of this study, two different types of carbon nano-fillers (F1 and F2) with different surface properties and sizes were added to two different asphalt binders: the base binder and the polymer modified binder. Also, mastic samples were prepared by replacing parts of the limestone filler by the carbon nano-fillers. It was observed that the nanoscale additives interacted with the binder quite differently. Additive F1 did not show a drastic improvement in the mechanical properties, fatigue resistance, and rutting resistance of the base and polymer modified binder at the mastic and the binder scale; however, additive F2 improved all the above- mentioned properties. From the experimental investigation, it can be inferred that part of the polymer modification can be replaced by additive F2. Although additive F1 showed a minimal change, it could be useful in improving the secondary application of the pavement, such as the electrical conductivity, thermal conductivity, and absorption of radiation for energy storage, which was not the scope of this study but appears worthy to investigate

The cornhusk and corncob are part of plants that can be used as the base material of paper art. They have a high cellulose fiber content. The purpose of this study to determine the tensile strength, tear strength, and sensory test of art paper from cornhusk and corncob. This study used an experimental method with a completely randomized design (CRD) factorial design, with 3 repetitions. Factor 1 is the ratio of cornhusk with corncob (A), A1 (1: 1), A2 (1: 3), and A3 (3: 1). The second factor is the addition of teak leaves (B), B1: without teak leaves, B2: teak leaves 25g, B3: teak leaves 50g. The results showed art paper with the highest tensile strength and tear strength at treatment A3B3 (75g of cornhusk + 25g of corncob + 50g of teak leaves) 13.7116 N. Art paper with the lowest tensile strength at treatment A2B3 (25g of cornhusk + 75g of corncob + 50g of teak leaves) 6.9821 N. Art paper with the lowest tear strength at treatment A2B1 (25g of cornhusk + 75g of corncob without teak leaves) 7.6681 N. Art paper whose the most preferred is the treatment A3B1 (the color is yellow / bright, the fiber is not visible, and the texture is very smooth) and treatment A3B3 (the color is dark brown / assertive, the fiber is visible, and the texture is rough)

[Review of] William N. Fenton. The False Faces of the Iroquois

This scientific and artistic tome on Iroquois Indian masks, literally a coffee table book, has been a long time in production. It is the culmination of over sixty years of interest and study by William N. Fenton, deservedly acknowledged as the dean of Iroquois studies. The author\u27s interest in the subject began during his childhood when he spent summers at his family\u27s farm in up-state New York. His grandfather, W.T. Fenton, had obtained two masks from Amos Snow, an Iroquois friend and neighbor, during the mid-nineteenth century. His father, J. W. Fenton, acquired more than a dozen additional masks as part of his vocation as an artist. So it is not surprising that the young William Fenton turned to anthropology in college and returned to the descendants of Amos Snow to pursue his consuming interests in Iroquois culture and history. Fenton\u27s first article on Iroquois masks and the Society of Faces was published in 1937. During subsequent decades, he studied over 1,500 masks in museums and private collections throughout the United States, Canada, and Europe
