Abstract

According of air pollution technology can be reduced by two methods: by using the Oceans method or Biosphere method. Oceans method known  a way that is burying CO2 in the deep of sea water of oceans. Biosphere method is known as the method of using natural and plant, namely by multiplying the trees in the neighborhood that will create air quality in the surrounding environment is increased. With this method made design research tool that room 1 and room 2 with dimensions of 50 cm x 50 cm x 100 cm with isolated condition. In the first room filled with gas emission vehicle for 60 minutes and then measured by a gas analyzer in order to determine the composition of vehicle exhaust emissions. Gas emissions of vehicles streamed into the room space 1and  2 by using a blower  through 3 pieces of flexible hoses. In room 2 vehicle emissions react with activated carbon and tree to absorbs CO2 from vehicle emissions, then for 60 minutes once for 5 hours of data taken and observed. Research results show, with the absorption of CO2 emission and method biosphere technology is very significant influence as evidenced from the graph of CO2 emission and absorption of O2 release to the environment. Variations trees greatly affect the ability of absorption of CO2 gas emissions and O2 release to the environment, also the effect of adding activated carbon additive affects the absorption process of the addition of CO2 emissions and the release of O2 into the environment with a total absorption of 60% CO2 and release O2 at 5.8%. Trees are able to absorb the most CO2 emissions in the period of the most rapid and release O2 is trambesi tree with a total absorption of 80% CO2 and the release of O2 by 7.2% with a time of 300 minutes with the absorption of 3.33 ppm. m2 / min.

Abstract

Fruit Football is a type of plant that is widely available in Aceh and is not utilized by the community. This research will be studied in experiments of fruit fooball as biofuel in diesel engines. Diesel engines are used in this test is a single cylinder four stroke engine water-cooled Yanmar brand, type TS 50 with specs: Maximum Power 5 HP, maximum rotation 2400 rpm, maximum torque 2.29 kg.m at 1600 rpm and compression ratio 17.9: 1. Performance testing is done with a diesel engine intended to determine the amount of power generated, the level of fuel consumption, specific fuel consumption and thermal efficiency. Testing is done with two variations of biodiesel fuel that B-10 and B-20 as well as diesel fuel for comparison. The results obtained from this study is that the power generated from diesel fuel is greater than the other two fuels, while more efficient fuel consumption B-20 followed by B-10 and diesel fuel. Specific fuel consumption results are varied while the higher thermal efficiencies generated by the B-20 of the B-10 and diesel fuel at high speed.

Abstract

Lives of traditional salt farmers increasingly concerned about the unfavorable business caused by the difficulty in obtaining fuel. The use of traditional stoves for salt farmers also without a good smoke channel, making smoke pollution that is harmful to health, and also interferes with the farmers and the environment while producing salt. Therefore, it should be considered a solution to address both of these issues by improving the combustion process that occurs in the combustion chamber and by utilizing the exhaust gas heat as a preheater in the salt process. Good combustion requires sufficient air supply with a certain excess air so that the combustion process is perfect. Air supply can be done by utilizing the natural drought affected by the height of the chimney. Utilization of flue gas has been done by creating a configuration flue gases channel through the multiport stove. Testing with chimney height variation needs to be done toget the optimal height so that stove can work with a good performance to produce salt. The results showed that the optimum height of the chimney in the semi-modern salt stove is at a height of 1.55m with a thermal efficiency of 48.6%.

Abstract

The boat propellers are needed for fishing boats in Aceh Province, considering that most Acehnese people geographically live along the coastline. Their income apart from farmers is fishermen. Currently, the metal ship propellers are imported from outside Aceh Province, so metal casting technology is needed to produce these ship propellers. There is already a small-scale industrial for metal casting, and the location is in Baet Lampuot - Aceh Besar District. The metal casting industry is currently producing rencong souvenirs to support tourism. However, when the Covid-19 Pandemic hit Aceh in particular and Indonesia in general, there are needed an alternative metal production business with other types of product variants, one of which was a ship cast-propeller. Based on this, Mechanical Engineering and FKIP Physics Department of Universitas Syiah Kuala improve the rencong metal casting industry to develop its products, to produce ship propellers through the Higher Education Leading Community Empowerment Program (PPMUPT) funded by the Ministry of Research and Technology /National Research and Innovation Agency of the Republic of Indonesia (RISTEK/ BRIN). The ship propeller product developed from waste metal, it recycled through metal casting technology. So the program and technology developed, is very useful not only for growing the regional economy but also in terms of handling the environment by recycling waste metal. Therefore, the community service program carried out by Mechanical Engineering and FKIP Physics Department of Universitas Syiah Kuala is right on target and in line with expectations.

Abstract

Combustion of biobriquette produced from coal and palm shell generate considerable energy. However beside generating biobriquette energy it also produces emissions gas. Emissions gas resulting from combustion include SOx, NOx, CO and CO2. Calcium is an adsorbent often used to adsorb released SO2 gas in the combustion process. The purpose of this study is to seethe effect of combustion temperature and type of adsorbent used in biobriquette to evaluate the efficiency of absorption of SO2 and the kinetics of the reaction of SO2 gasabsorption as a function of combustion biobriquette ratio Ca/S (mol / mol) on coal and palm shell ratio of 90:10 (w/w). In this study, the ratio of Ca/Swas Specified at1:1, 1.25:1, 1.5:1, 1.75: 1 and 2:1. Combustion temperatures used were 300, 350, 400, 450 and 500°C. The result of this study showed the decrease levels of SO2 for scallop shell and green mussels  was highest at the ratio Ca/S2: 1. The highest absorption of efficiency adsorbent for scallop shells are produced at the ratio of Ca/2:1 at temperatures 400°C, equals to 90.59%. Meanwhile for the green mussels, the highest efficiency was resulted ratio of Ca/S 1.5:1 at temperatures 400°C which was equals to 84.74%. Reaction rate constants of absorption in the biggest adsorbent of scallop shells produced at ratio Ca/S 1:1 equals to  0.265, while the biggest reaction rate constants of adsorbent green mussels produced at being Ca/S 1.5:1equals to  0,198.

Abstract

The effect of engine loading on emission of particulate matter was studied by using an Otto engine (Honda astrea grand 110 cc). In the experiment, the characteristics of loading engine, fuel consumption and composition of particulate matter were investigated. The engine loading was determinated in term of engine transmittion, the fuel consumption was measured by using plastic tube scale, and composition of deposit particulate matter was analyzed by using spectrophotometer. The experimental results show that the quantity and fuel consumption was increased by the increasing engine loading. The deposite of particulate matter was generally characterized by organic carbon content.Keyword: motor bensin, emisi debu, transmisi
