Abstract

Usage of type alcohol of etanol in gasoline fuel proves a number of machine achievements in terms of parameters, namely actual horsepower, specific fuel consumption, mean effective pressure and thermal efficiency compared to use pure premium fuel. Level of such repair gyrate 73% from maximum energy according to machine specification. In yielding etanol, fermentation process with yeast mixture then destiltaion. Etanol mixed with premium with certain ratio. In this research, variation of mixing of alcohol premium, namely: 95%+5%; 90%+10% and 85%+15% by 3 variation  throttle opening: 20%, 40% and 60%. The result indicates that with usage of concentration mixing of premium + etanol, reached actual horsepower by Kijang machine 7k experiencing with maximum value equal to 17,347 kW that happened at condition of opening of throttle 60% at rotation 2100 rpm with usage of mixing 95% premium + 5% etanol. With usage of concentration mixing of premium + etanol, specific fuel consumption also experience with maximum value equal to 0,331 kg/ kWh that happened at condition of throttle opening by 20% within rotation of 2100 rpm with usage of mixing 90% premium + 10% etanol.

Abstract

Sugarcane (Saccharum officinarum L.) is a raw material that is processed to produce crystal sugar and bioethanol. The process produces sugarcane bagasse. In this study, The liquid-plasma treatment based on microwave plasma in the liquid was used to treat sugarcane bagasse to observe the effect on glucose concentration and gain byproducts. The energy input parameters were varied by 340, 360, and 400 W with irradiation time variations of 1, 3, and 5 minutes. Nelson Somogyi's method was used to determine the percentage of glucose as well as Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscope (SEM), and Image-J software to characterize the side-product of the samples. The results showed that the glucose concentration reduced around 27.6% - 99.2 % after microwave plasma in-liquid treatment at the energy input of 340 Watt and 360 Watt, respectively, with an irradiation time of 5 minutes. The side-product is cellulose nanoparticles which have an average diameter of 92, 106, and 169 nm

Abstract

Public services are interactions between society and the government as public servants. This service activity involved the Pinrang Regency Investment and Integrated Service Agency (DPMPTS) and academics from the Mechanical Department, Faculty of Engineering, Hasanuddin University. Utilizing this disinfectant tool can help the DPMPTS service in terms of air sterilization and preventing the spread of Covid-19 in community service spaces. The problem that arises is the level of interaction between the community who needs services and DPMPTS employees as service providers who are quite vulnerable to the spread of viruses and bacteria. This can cause the spread of disease, so tools are needed that can reduce the impact of the spread of the disease. The use of Ultraviolet C (UVC) is a disinfectant tool that has been proven effective in killing microorganisms, one of which is the COVID-19 virus. The service method is carried out using an outreach mechanism at the DPMPTS agency which is attended by technical government agencies and several participating local communities. The process of implementing socialization uses a questionnaire mechanism consisting of pre-test and post-test. At the start of the socialization, the number of respondents who filled out the questionnaire was 18 people consisting of 8 government representatives and 10 community representatives or a total of 18 respondents. In the pre-test results, it was found that only 3 people understood the function of the mobile robot disinfectant system mechanism and 15 people did not understand. After the socialization was carried out, better results were obtained with 17 people who understood and 1 person who still did not understand the working system of the mobile disinfectant robot. Therefore, it is recommended to use mobile disinfectant robots in DPMPTS public service spaces to reduce the effects of spreading viruses and bacteria.
