Abstract

Plastic waste is one type of waste that can not be broken down into the organic waste. Utilization of waste plastics to be recycled into plastic with better quality are rarely implemented. This study aims to utilize plastic waste in order to improve the quality of plastic products by Taguchi experimental design method that combines the pure plastic material composition of ore and recycled plastic (type PP/Polypropilena) with a certain pressure and temperature to produce a tensile strength of the plastic the better. From the experimental results, btained by a combination of material composition of 30% recycled plastic, the pressure of 6.5 atm and a temperature of 180 °C. The composition obtained by the average tensile strength of 991.667 Newton, and Signal to Noise ratio (Larger is better) by 59, 9255. Statistically, tur ulang he combination was significantly affected by alpha at 0:05 Taguchi method through experiments with a matrix orthogonal array L8 (23).

Abstract

Many small industries have difficulties to survive or to develop their business. The CSSF (contingent strategic success formula) approach was used to analyze the formula of success strategy combining with internal and external factors of the companies, i.e. to measure, to estimate, and to forecast the condition of environmental companies in this time and the future. Measuring. The internal factors of the companies was aimed to know everything that improved so that follow the external needs condition in the future. In order to succeed in the future, companies need to follow the optimal internal and external condition with turbulence level by use three points of the marketing methods, are to build the product positioning at specific area business, to build a robust differentiation and to build the brand images or emotional relationship with customers.

Abstract

Mesin pembengkok pipa merupakan alat yang digunakan untuk mengerol pipa, apakah pipa silindris atau pipa kotak dengan menggunakan penggerak utama motor listrik. Alat ini sangat diperlukan dalam proses pembuatan pagar atau rangka kanopi yang terbuat dari bahan logam agar proses pembengkokkan bisa lebih cepat dan diperoleh hasil yang baik. Prinsip kerja dari alat ini adalah pipa yang akan dibengkokkan ditekan oleh poros penggerak utama yang berputar, sedangkan dua poros yang lain menahannya. Karena poros utama bergerak bolak balik maka semakin lama pipa akan membengkok. Tahapan dalam proses pembuatan meliputi perancangan (desain), pemilihan bahan dan pembuatan. Perancangan dilakukan agar diperoleh desain alat yang sesuai dengan kebutuhan. Pemilihan bahan dilakukan untuk menentukan bahan-bahan yang digunakan dengan mengutamakan fungsi dan nilai ekonomis dari sisi harga. Untuk bahan rangka dipilih besi profil U, sedangkan untuk bantalan poros dipilih bantalan yang sudah ada di pasaran. Alat-alat utama yang digunakan dalam proses pembuatan yaitu mesin las listrik, gerinda potong dan peralatan keselamatan kerja dalam proses pengelasan. Dari pembuatan yang dilakukan dihasilkan alat/mesin pembengkok pipa dengan penggerak utama motor listrik yang dapat digunakan untuk membengkokkan pipa diameter 1 inci dengan ketebalan 1,2 mm. Key words: pembengkok, pipa, poros utama

Abstract

The using of plastic in human life is increasing over time. This increase occurs because plastic is not easily broken, flexible, practical, economical, and can replace the function of other items. One of the plastic molding processes is Injection Stretch Blow Molding, a plastic molding machine method that combines two processes, namely injection molding and stretch blow molding. The injection stretch blow molding process is a plastic molding machine that is melted and then injected into the mold to form a preform that is stretched and blown to form the product. This machine has a high level of precision so that the aspects of strength and appearance quality on the packaging bottle are the main assessment. The aim of this research is to determine the effect of temperature parameters on black spots, stripes and stripes on 100 mL PET bottle products. It is necessary to handle chiller temperature, hot runner temperature as independent variables in printing preforms.  The control variables are material composition, cycle time, holding time, and component gap position. This type of research is experimental research and the processing method used in this research uses the design of experiments using statistical software. The level of variation in hot runner temperature parameter settings is 265°C, 270°C, and 275°C and chiller temperature is 17°C, 18°C, and 19°C. From the results of this research, it can be concluded that the significant parameters used for the chiller are 18°C, the appearance defect is 0.2% and for the hot runner it is 270°C, the appearance defect is 0.4%. This number is a significant parameter that produces fewer appearance defects for 100 mL PET bottle products in order to reduce the number of rejects.

Abstract

This study aims to analyze the effect of various operational factors on the weight of dust collected by a dust collector machine. Using a multilevel factorial design, this study evaluates the interaction between frequency (Hz), hose length (m), and tube height (m). Analysis of variance shows that all three factors have a significant effect on the dust weight response (P-Value <0.05). The regression model with an R² of 99.15% shows a very high prediction accuracy. Parameter optimization was carried out to maximize the weight of dust collected, resulting in optimal conditions at a frequency of 50 Hz, a hose length of 2 m, and a tube height of 0.3 m with a dust weight of 72.75 g.

Abstract

This study aims to determine the effect of volume fraction, fibre angle direction, and fibre length on the impact strength of squid fibre-reinforced composites. Squid fibre is a natural animal fibre that has excellent potential in the development of composite materials. The use of squid fibre as a composite reinforcement can be an alternative to reduce organic waste from marine products and produce new composite materials in sustainable manufacturing applications. The research method was conducted with quantitative experiments to determine the effect of fibre volume fraction with variations of 25%, 50%, and 75%; fibre angle direction with variations of 45° and 90°; and fibre length with variations of 20 mm, 30 mm, and 40 mm. This study used the Factorial DOE statistical data analysis method. The results showed that volume fraction and fibre length significantly affected the impact strength of the composite. The higher the volume fraction and fibre length, the higher the impact strength value of the composite. Meanwhile, the direction of fibre did not show a significant effect. The 75% volume fraction produced the highest impact strength of 0,0738 J/mm², and the 25% volume fraction produced the lowest value of 0,066 J/mm². The 45° fibre direction produced an impact strength value of 0,07098 J/mm², and the 90° fibre direction produced a value of 0,07097 J/mm². The 40 mm fibre length produced the highest impact strength value of 0,078 J/mm², and the 90° fibre direction produced a value of 0,07097 J/mm².
