Abstract

Plastic bag type waste is a type of Low-Density Poly Ethylene (LDPE) plastic waste whose presence in Talang Gulo Final Disposal Site in Jambi City is not touched by scavengers because it cannot be resold. This condition resulted in the destruction of this type of plastic bag waste by burning it. Destruction of plastic waste by means of incineration is risky to the environment because pollutants will emit pollutants from CO2, CO, NOx, and SOx exhaust emissions as well as some other pollutants in addition to the general nature of plastic waste which cannot be decomposed by microorganisms on the ground. Efforts to minimize environmental pollution due to plastic bag type waste will be processed using a pyrolysis method using a reactor with temperatures of 250ºC - 450ºC and 65 psi - 65 psi as well as energy-efficient condensers that have high thermal conductivity to produce fuel oil as energy sources. The maximum volume of fuel oil is obtained by a 6hour pyrolysis time of 2,560 ml at a temperature of 450 ºC. The test results for density parameters, specific gravity, water content, flash point, and heating value indicate that the fuel produced meets Indonesian fuel quality standards.

Abstract

Cassava is a type of tuber that is very much found in the Jambi region. Cassava is easily damaged and decayed in a period of about two to five days after harvest, if it does not get good post-harvest treatment. It is necessary to process cassava crops into chips. To get the results of cassava chips that are good, there is a machine that can produce homogeneous chopped results. Besides that, it is expected that the cassava chopper machine can produce chopped with several forms of chopping. This study aims to make the design of multi-blade cassava chopper machines so that three types of chopping shapes can be produced with only one machine. Based on the results of the study, cassava chopper machines were produced with dimensions of length 630 mm wide by 390 mm and height of 450 mm. This machine uses a straight round multi-blade dish, waves and sticks. The capacity of this machine is 54 kg / hour and the power used is 185 watts.

Abstract

Refrigeran is a major component in an Air Conditioner (AC) system. AC is a cooling system used as a room temperature conditioning tool, so it is comfortable to use in indoor activities. The refrigeran pressure in the cooling system can reduce the air conditioner's ability to condition the room temperature. The purpose of this study was to determine the coefficient of performance (COP) value of refrigeran R-134a with variations in refrigeran pressure of 100, 125, and 150 psi. The parameters studied were the compressor's energy consumption, the cooling capacity, and the COP value. Energy consumption is calculated based on the compressor power multiplied by the length of time the compressor is operated. The results show that the COP value decreases with an increased operating time of the cooling system; this indicates that energy consumption increases with increasing refrigeran pressure.

Abstract

The blower is a device used to increase the air pressure and increase the flow rate of air and gas. In this study, the effect of the inlet and outlet valve openings of the ring blower was experimentally investigated. Variations in the inlet and outlet valve openings are 50%, 75%, and 100%, respectively. The results showed that the larger the opening of the inlet and outlet valves, the greater the flow capacity (Q). Furthermore, the larger the inlet and outlet valve openings, the lower the ring blower air flow pressure (P).

Abstract

Inorganic waste is rubbish that cannot be broken down by nature such as metals, plastics and glass. Garbage for the city of Jambi is a problem that has not been resolved to date. One example of the type of metal waste that can be managed is Aluminum such as used beverage cans. One way that technology can be developed to treat aluminum waste packaging for used beverage cans (soft drinks) is by way of recycling. The method that can be used is the hydrolysis process to produce hydrogen gas as stove fuel. The hydrolysis process is carried out by mixing Sodium Hydroxide, Aluminum, and Water. An analysis of the composition of Aluminum, Water and Sodium Hydroxide (NaOH) is carried out to produce maximum hydrogen gas with a fixed reactor volume. the results of research conducted obtained the volume of H volume gas formed, the highest pressure and temperature (130 l, 200 psi and 100 ° C) with the use of maximum reactants, namely aluminum from 400 g canned waste and 4N NaOH. NaOH acts as a catalyst in the aluminum reaction and water forms NaAl (OH) ₄ which releases hydrogen gas in the exothermic reaction..
