Abstract

The insect Callosobruchus maculatus, is responsible for serious damages in the storage of grains of diverse cultures, among them, the one of the beans. Therefore the development of substances capable of being an alternative to minimize agricultural losses and thus contribute to food security of the population is a current necessity.This research aims to explore new materials derived from natural fibers for the development of environmentally friendly and recyclable medical devices, particularly prostheses. The focus is on utilizing ramie fiber, a natural fiber, as a substitute for artificial fibers and plastics in composite materials. The study investigates the impact and bending strength of ramie fiber composites by varying the volume fraction and fiber orientation. The experimental design involves three volume fractions (1%, 3%, and 5%) and three fiber orientations (10°, 20°, and 30°). Hand lay-up method is employed on molds, ASTM D256 impact tests and ASTM D7264 bending tests are conducted to assess the mechanical properties. The findings indicate that the ramie fiber composite with a volume fraction of 5% and fiber orientation of 30° exhibits the highest bending strength, measuring 471.1 Mpa. Similarly, this composition demonstrates the highest impact strength value of 26,558,720 Pa. Overall, this research contributes to the advancement of sustainable materials for medical prostheses and highlights the significance of optimizing the composition of ramie fiber composites to enhance their mechanical properties.

Abstract

This study investigates the advantages of using active carbon as a catalyst, including its deodorizing and color adsorption properties, its ability to act as a purifying agent, common adsorbent, and permeable membrane. Additionally, active carbon exhibits strong binding power to substances that are physically or chemically separated. The objectives of this research are to compare the exhaust gas emissions of motorcycles before and after the application of an adsorbent on the muffler and to analyze the effects of active carbon derived from coconut shell on the engine speed of carbon monoxide (CO), and hydrocarbons (HC). The experimental approach involved conducting laboratory experiments with varying masses of active carbon to collect data. The independent variables were the mass of active carbon and the engine speed, while the dependent variables were the emissions of CO, and HC. The results indicated that using 200 grams of active carbon derived from coconut shell as an adsorbent resulted in a 12.06% decrease in CO emissions, and a 16.96% decrease in HC emissions. Keywords: Active Carbon, Exhaust Gas Emissions, Coconut Shell

Abstract

Fossil fuels have become one of the main causes of increasing pollution in the world, especially in Indonesia. Comparisons between proposed bio-acetone fuel blends and other biofuels were introduced in a unique study. bio-acetone is a promising alternative and can improve performance and emissions over the others. The aim of the research was to determine the optimization of the ratio of bioethanol, bioacetone-Ron 90 to power and exhaust emissions (HC and CO). Fuel mixture ratio bioethanol, bioacetone - RON 90 ((3:7:10), (5:5:10), (7:3:10), (10:5:5), (7,5:7, 5:5), (5:10:5), (2,5:2,5:15), (3,5:1,5:15), (1,5:3,5:15)) and engine speed (2000, 3000, 4000, 5000, 6000) 110cc gasoline engine rpm. The data processing method uses the Response surface method. The results of research on power and emission tests that have been optimized, the optimum value for fuel ratio power at standard spark plugs, at a ratio of 1.5:3,5:15 and Rpm 4424.24 with a power of 8.02065 HP. The optimum value for HC emissions is at a ratio of 3:7:10 at Rpm 4222.22 and HC gas emissions are 43.9879 ppm. Optimum value for CO emissions at a ratio of 7.5:7.5:5 and 2000 rpm with a CO emission of 0.208712%. Keywords: Optimization Bioethanol, Biocetone, Power and Emissions

Abstract

The purpose of this study is to analyzes of the process of purifying bioethanol produced by a distillation apparatus that uses two holes of different heights. The equipment used in this study is a distillation prototype tool which has two steam holes coming out of the vessel, with different height positions. The research method used is experimental. Data collection was based on the results of distillation experiments with the independent variable alcohol content in the solution, the dependent variable alcohol content resulting from the distillation process and the control variable is steam temperature and processing time. The results of the study were processed with statistics showing that the position of the holes affects the product resulting from the alcohol content in bioethanol, a high hole position will produce bioethanol with a greater alcohol content. The alcohol content in the solution that is put into the distillation vessel affects the distillation results, the greater the alcohol content, the greater the alcohol product. The interaction between the position of the holes and the alcohol content in the solution affects the amount of alcohol product in the bioethanol. input solution containing low alcohol cannot reach the distillation results of bioethanol with high alcohol content. Bioethanol through the top hole has a higher alcohol content than that through the bottom hole. The alcohol content in the solution affects the difference in the alcohol content produced between the upper and lower holes. Distillation can produce bioethanol with a high alcohol content of up to 96%, with a solution containing about 85% alcohol. This distillation process can be done privately so that everyone can make fuel for their own vehicles. Keywords: Bioethanol Purification, Distillation System, Purifying Bioethanol

Abstract

Squeeze force, rivet length, rivet diameter, and hole clearance are the factors that affect the riveting procedure and the effectiveness or result of the rivets. In this riveting simulation, the riveting parameters are determined using a semi-automatic riveting tool. The semi-automatic riveting tool's working pressure is the parameter set, and the hole clearance is created during the drilling process on sheet metal. The results of riveting simulation show that the working pressure of the rivet gun and the hole clearance directly impact the rivets' shear strength. The shear strength of the rivets will increase with higher operating pressure of the rivet gun and larger hole clearance. Due to the strain hardening that occurs when rivets are hit with a rivet gun during the riveting process, the shear strength of rivets has increased. Keywords: Rivet Gun Pressure, Hole Clearance, Shear Strength
