Abstract

It is estimated that fossil fuels will run out if they are exploited on a large scale. In today's developments, there are many vehicle innovations that use diesel fuel. This dependency can be overcome with bio diesel. Various wastes resulting from the processing of agricultural materials have great potential to be processed into alternative fuels to replace coal and fuel oil. These alternative fuels include bioethanol, biodiesel, biogas and biobriquettes. In this research we discuss biodiesel, biodiesel is an alternative fuel which is usually made from agricultural plants such as oil palm. However, this fuel usually cannot be pure oil, usually mixed with diesel. This mixed fuel has not been proven to be good for use in vehicles in the sense that this fuel might affect the torque of the vehicle. In this research we will test which mixture is the best or closest to fossil fuel.

Abstract

Water is a source of life, but it is very easily polluted because water is known as a universal solvent and is able to dissolve many substances. Water pollution is the pollution of water bodies (seas, lakes, rivers, groundwater) caused by human activities. To obtain water that meets water quality standards, it must be supported by an appropriate water treatment system, one of which is the water treatment tool in this research, called AFRO. AFRO works with a reverse osmosis filtration aeration process. Previously, AFRO was developed to treat raw water containing dissolved impurities. However, the results are less than satisfactory, so it needs to be developed further to meet the need for clean water that can be utilized by the community. The development of AFRO in this research is based on the House of Quality (HQ) matrix. From this HQ matrix, a presentation of development priorities was obtained from the previous one in the form of design changes of 16.1%, material changes of 9.6%, processing processes of 14% and energy changes of 9.2%. From the tests that have been carried out, this time AFRO can process raw water from dissolved and insoluble impurities. This tool is also equipped with a solar energy utilization system. The AFRO water treatment process developed consists of (1) chemical process, (2) aeration, (3) filtration, (4) reverse osmosis and (5) disinfection using ultra violet (UV) light.

Abstract

Noise refers to unwanted sounds emanating from production equipment or work equipment, which are potentially harmful. The most common factor affecting workers is noise, which can impair hearing. The impact can be both psychological and biological problems. To solve this problem, noise-absorbing materials that can be installed in various places are needed. One of the proposed solutions is the development of acoustic materials made from easily available natural fiber composites, such as areca nut fibers. Areca fibers are integrated as a base material for acoustic materials that aim to reduce outdoor noise or from building structures. In this study, 2 testing methods were carried out, namely the Sound Absorption Coefficient (α) Test and the Fourier Transform Infrared (FTIR) Test. The Sound Absorption Coefficient Test aims to measure the ability of materials to absorb sound energy, while FTIR is used to analyze sample components without damaging them. The sound absorption coefficient test results showed that the samples were able to absorb sound at a frequency of 800-1600 Hz. After the areca fiber was treated with NaOH, there was a change in the O-H group which indicated a reduction in lignin content in the areca fiber. This O-H group shift causes an increase in adhesion between the matrix and filler in the composite.
