Abstract

Motor performance is one of the things that must be considered in motorized vehicles. Motor performance also influences the type of exhaust system, namely the muffler. Many people don't know how big the influence of the exhaust free flow on engine performance. In this study using Yamaha Nmax Old 2016. The aims of this study were: (1) To find out the difference in torque and power produced by a motorbike between the use of a standard NMAX 155 CC exhaust and a standard exhaust free flow. (2) Knowing the difference in fuel consumption produced by motorcycles between the use of a standard NMAX 155 CC exhaust and exhaust free flow. (3) Knowing the difference in exhaust emissions produced by motorbikes between the use of the standard NMAX 155 CC exhaust and the exhaust free flow. The research method used is experimental. The data for this study were obtained by measuring a sample of the Yamaha NMAX Old 2016 motorcycle. The independent variables were the standard exhaust and the exhaust free flow. The dependent variables are torque, power, fuel consumption and exhaust emissions. The data obtained were then analyzed using quantitative descriptive techniques by describing them in the form of graphs and tables. The results of this study are: (1) Use of Muffler free flow has a lower effect on the torque and power generated by the Yamaha NMAX Old 2016 motorcycle. (2) Use of Muffler free flow has a higher effect on fuel consumption produced by Yamaha NMAX Old 2016 motorbikes. (3) Use of Muffler free flow has an influence on increasing levels of exhaust emission content produced by Yamaha NMAX Old 2016 motorbikes.

Abstract

This research was conducted to investigate the effect of binder variation including bentonit, lapindo mud, and portland cement on the silica molding sand strength, permeability, fluidity, metal hardness and the quality of Al-Si alloy casting by using gravity casting method. The experimental design was used on this research and analyzed by using descriptive data analysis. The result showed molding sand containing 15% lapindo mud binder had the highest wet compressive strength (8,73 N/cm2). The molding sand containing 15% portland cement binder had the highest dry compressive strength (>32 N/cm2). The highest wet tensile strength was resulted by the molding sand containing 15% bentonit binder (3,33 N/cm2), while the highest dry tensile strength was resulted by the molding sand containing 15% portland cement binder (18,60 N/cm2). The highest wet shear strength was resulted by the molding sand containing 15% portland cement binder (0,57 N/cm2), while the highest dry shear strength was resulted by the molding sand containing 15% portland cement binder (1,03 N/cm2). The molding sand containing 15% bentonit binder had the finest permeability (210 mm/minute). In the real practical application, the molding sand containing 15% portland cement binder was unable to result an appropriate molding strength when manually compressed in cope and drag (casting flask), thus it was unable to use as metal pouring media. The molding sand containing 15% lapindo mud binder had the finest fluidity but it had the lowest hardness (120,30 HV). The molding sand containing 15% bentonit binder resulted the best Al-Si alloy casting quality and the highest hardness (129,60 HV).

Abstract

The competency gap between vocational high school (SMK) graduates and industrial needs triggers high unemployment rates. Teaching Factory (TEFA) emerges as an innovative learning model to address this issue. This study aims to describe the TEFA management strategy implemented at SMK Ganesha Tama Boyolali. The research approach used is qualitative with a case study design. Data were obtained from eight informants through in-depth interviews, participant observation, and documentation studies. The data analysis technique followed an interactive model encompassing data reduction, data display, and conclusion drawing. The research results indicate that the TEFA management strategy is implemented through five main pillars: (1) strategic planning based on market analysis and curriculum synchronization with PT D-Tech Engineering; (2) strengthening partnerships through technical assistance and resource sharing; (3) functional organizational governance adopting corporate managerial structures (Production Manager, HRD, and GA); (4) operational implementation based on real orders (order-based) with a three-shift system ; and (5) a digitized monitoring system utilizing a geotagging attendance application. The integration of these five management pillars ensures the systemic relevance of vocational education to industrial standards.

Abstract

Abstract. The main objective of this study was to analyze the effect of Natural Weathering on the tensile strength and microstructure of recycled polypropylene (rPP) composites with bamboo fiber reinforcement. The rPP-bamboo composite specimens were made using extrusion molding and injection molding machines. The weight fraction used in making the specimens was 10% bamboo fiber and 90% rPP. The rPP-bamboo samples were tested with 3 variations of exposure time, 0 months (without exposure), 1 month and 2 months according to ASTM D1435-05 standard. From the 3 variations of exposure, a tensile test was carried out with the ASTM D638 type V standard to evaluate the value of tensile strength, modulus of elasticity and elongation. Then SEM (Scanning Microscopy Electrone) was performed to see the microstructure of the composite. The results showed that the tensile strength at exposure time of 0 months, 1 month and 2 months was 18.1 MPa with an elongation of 5%, 19.5 MPa with an elongation of 6.4% and 19.3 MPa with an elongation of 6.6%. Young's modulus values showed a decrease with increasing exposure time, ranging from 222 MPa in the sample without exposure to 141 MPa at an exposure time of 2 months. With SEM it is known that, the microstructure of the composite at the beginning of exposure shows a strong bond between the fiber-matrix even though there are some voids in the specimen. At 2 months of exposure, it was seen that there was a gap between the matrix and bamboo due to the hydrophilic nature of bamboo fiber.
