Elasticity analysis of straps cut from used motorcycle tires done for determine (1) deflection effect to wide pieces of used tires, (2) modulus elasticity of used motorcycle tires, (3) used motorcycle tires applications for construction materials building earthquake resistant houses. Testing was conducted by One Point Loading (OPL) or a single centralized load testing. Data collection was performed by measuring the deflection at loading 1-10 kg with independent variable widths pieces of used tires. Modulus of elasticity obtained from the equation deflection. Data were analyzed with descriptive methods - quantitative regression analysis. Modulus elasticity of used motorcycle tires compared with the modulus elasticity of the construction materials. concluded that the larger the width of pieces of used tires, which occurs the smaller deflection. The modulus elasticity of used motorcycle tires is 8727.976 MPa which indicates that the used motorcycle tires have good flexibility. Straps cut from used motorcycle tires can be used as a construction material in addition to the retaining wall as a building collapse caused by the earthquake. Keywords: Elasticity, used tires, earthquake resistant houses.

The dye is widely used in the industry which came dye textiles, plastics, and batik. Results of waste as a result of the dye can cause poisoning which is very dangerous. Waste methylene blue into one of the results of waste textile color. Charcoal from waste tree trunks using adhesives PVAC successfully made into a carbon that is able to absorb the waste dye methylene blue. Making carbon with PVAC adhesive into new things that are simple to absorb waste dye and easy to do by the general public without the use of laboratory equipment. The purpose of this study was to determine the effect of variation of immersion time and the mass of charcoal to the transmittance and absorption of waste degradation methylene blue 67 ppm. Degradation of methylene blue waste generated by providing independent variable mass quantities of charcoal trunk as much as 3g, 6g, 9g, 12g, 15g and 18g and variable time soaking for 12 hours and 36 hours. The concentration of methylene blue before and after irradiation was measured using a UV-Vis spectrometer. The results showed that the soaking time and the amount of carbon affect the absorbance and transmittance of methylene blue waste. The more the sheer number of masses of charcoal and charcoal long soaking time, giving the plot a graph of absorbance down and plot a graph of transmittance rose nearly perfect degradation. Keywords: Carbon, PVAC, Waste methylene blue, absorbance, transmittansion.

Pewarnaan rambut merupakan tindakan mengubah warna rambut untuk menutupi rambut putih, sesuai dengan warna yang diinginkan. Pewarnaan rambut dapat menggunakan bahan alami atau nabati , diantaranya dari biji-bijian. Biji pepaya mengandung bahan Glucoside cacarindan karpain yang menghasilkan zat warna hitam. Rambut indah seperti mayang terurai merupakan kiasan yang menggambarkan rambut yang indah, berkilau sekaligus merupakan gambaran rambut sehat. Karena hanya rambut sehat yang mampu menampilkan kecantikan secara alami. Untuk memiliki rambut yan sehat dibutuhkan perawatan yang sesuai dengan kondisi rambut. Perawatan dapat dilakukan secara alami dengan menggunakan bahan-bahan alami yang berkhasiat. Salah satu bahan alami yang digunakan adalah biji buah pepaya. selanjutnya data dianalisis dengan metode statistik deskriptif. Berdasarkan hasil analisis data, diperoleh kesimpulan bahwa biji pepaya mengandung glucoside cacarin dan karpain yang terdapat pada panjang gelombang 450 nm – 950 nm sehingga dapat dimanfaatkan untuk menghitamkan rambut dan rambut yang diberi pewarna alami mudah luntuk jika dicuci terua-menerus. Kata kunci : rambut putih, biji pepaya, hasil kelunturan warna rambut.

Final Disposal (TPA) is a disposal of the remains (garbage) activities of residents of organic to inorganic. Trash that has fulfilled the land will be relocated to another place so that the former is called the normalized TPA or the land back to the beginning of the function. The purpose of this study was to determine the direct shear test of TPA in the district of Kudus normalized to determine the water content test and direct shear strength test soil with soil variations normalized landfill and landfill soil that has not been normalized. The method used is to take soil samples tested in the laboratory and continued with retrieval data retrieval. Data were analyzed using 1D graph. Having done the research results that the water content in the TPA normalized ie 34,23% while the landfill soil that has not been normalized with 33,15%. To test the shear strength obtained TPA normalized graph of normal stress to shear stress resulting friction angle value 19,070 and the value of cohesion (c) 8561,7N/m2. To test the shear strength normalized landfill that has not obtained a graph of normal stress to shear stress resulting friction angle value 22,850 and the value of cohesion (c) 6429,9N/m2. Key words: land, landfills (TPA), normalized, direct shear test. &nbsp

PDAM water reservoir or water in the tub was hot during the day and less convenient to use for bathing. The water needs to be cooled down 2-50C to make it more convenient to use. One method that is inexpensive to cool water that pass through a gap broken bricks. The study was conducted by the length variation of water flow through the gap broken bricks. Furthermore, the temperature of the water before and after the gap of broken bricks were measured using a mercury thermometer. The analysis is done by comparing the tables and graphs to analyze the relationship between the length of the flow to the drop in temperature. The results showed that the most effective water cooling process by passing the gap of broken bricks a long stream of 1 meter. Keywords : cooling water , temperature , bricks.
