Abstract

Penelitian ini membahas tentang pengaruh variasi beban terhadap akselerasi dan konsumsi bahan Bakar. Tujuan penelitian ini adalah Mengetahui seberapa besar nilai tingkat Akselerasi dan Konsumsi bahan bakar yang dihasilkan dengan menggunakan variasi beban. Beban ditempatkan di muatan penumpang pada Mobil Tawon 664 cc masing – masing sebesar 80 kg, 160 kg, 240 kg, 320 kg, 400 kg. Pengujian akselerasi dilakukan di lintasan yang sudah ditentukan dengan membandingkan variasi beban terhadap muatan penumpang sebanyak 5 variasi beban yang berbeda, sedangkan Pengujian konsumsi bahan bakar dilakukan di lintasan yang sudah ditentukan dengan ukuran volume yaitu 100 ml per variasi beban yang berbeda untuk melihat jarak tempuh terjauh setiap percobaan. Pada jarak 100 m dengan beban 80 kg mampu mencapai sebesar 0,799 m/s. Hal ini menunjukan bahwa beban 80 kg menjadi nilai akselerasi yang optimal dibandingkan dengan variasi beban lainnya. Pada putaran mesin 2500 rpm variasi beban 80 kg mendapatkan sfc sebesar 0,1000 kg/kwh. Hal ini menunjukan bahwa beban muatan 80 kg menjadi konsumsi bahan bakar paling hemat dibandingkan dengan variasi beban lainnya

Abstract

Roof tiles play a vital role in the construction industry hagoslot by providing protection from the sun's heat and rain. The quality of roof tiles largely depends on the materials used and the manufacturing process, as these factors significantly affect the tiles' mechanical properties. Kangkung pagar (Ipomoea carnea) is one type of alternative natural fiber material that can be utilized in the creation of composite materials. This study aims to explore the potential of Ipomoea carnea powder as an alternative material for producing polymer roof tiles, as well as to examine how variations in the composition of powder and sand influence the mechanical properties of these tiles. The method for producing roof tiles is based on powder metallurgy. The composition of the powder and sand used varies in the following ratios: 10% powder to 50% sand, 20% powder to 40% sand, and 30% powder to 30% sand. Additionally, a fixed composition of 30% polyester resin and 10% asphalt is used. The initial process involves mixing the materials according to these predetermined ratios. The resulting mixture is then molded and compacted under a pressure of 200 kg/cm². Characterization of the mechanical properties includes proximate analysis, calculation of porosity and density, flexural strength testing, and hardness testing.The study's results indicated that the properties of polymer roof tiles are significantly influenced by the composition of the powder and sand used during their manufacture. The findings revealed a porosity value of 0.209%, a density of 0.994%, a flexural strength of 2.270 MPa, and an optimum hardness of 19.1 BHN. The addition of 10% powder increased the hardness value by only 0.4% while decreasing the flexural strength by 0.5%. Overall, the use of Ipomoea Carnea powder was not effective in enhancing the mechanical properties of the polymer roof tiles, as both the flexural strength and hardness values remained below those of commercially available polymer roof tiles.
