Abstract

This research was conducted to utilize durian seed waste into activated carbon and aims to identify the characteristics of the durian seed activated carbon produced from the activation temperature alteration. With an experimental method with a quantitative approach, the process of making durian seed activated carbon was tested by carbonization using an oven at a temperature of 200 oC for 180 minutes, then temperature activation with alterations of 500, 600, and 700 oC was held for 120 minutes in the furnace, and after it was added with chemical activation by using a 1,5 M H2SO4 solution for 24 hours of immersion. The analysis seen is to test the water content, volatile matter content, ash content, bound carbon content, and to see the surface morphology of activated carbon using SEM (Scanning Electron Microscopy). The results of the test obtained values for water content (6,83 – 12,73%), volatile matter content (16,98 – 26,89%), ash content (7,85 – 12,04%), bound carbon content(61,66 – 75,17%), with an increase in the activation temperature there is a tendency to decrease the value of water content, volatile matter content, ash content, and there is an increase in the value of bound carbon content. And visible cavities on the surface of the activated carbon along with the increase in activation temperature.

Abstract

Research has been done on the physicl test of charcoal briquettes made from tea stems (Camellia sinensis). This study aims to determine the physical characteristics of the charcoaI briquettes produced. This research is motivated by the increasing demand for human fuel, thus utilizing tea stems as the main ingredient in making briquettes. The sample variations used were tea tree trunk charcoaI and tapioca adhesive as an adhesive with a ratio of 90%:I0%, 80%:20%, 70%:30%, 60%:40%, and 50%:50%. The physical test carried out included water content, density, and calorific value. The results obtained from the physical test of biochar briquettes with the best quality approaching the quality standards of Indonesian briquettes were obtained on sample with a composition (70%:30%) with the value of water content, density, and calorific value, each of which was 5 .70%, 0.55 g/cm3, and (-) 7.62 cal/g.

Abstract

In the process of determining student beneficiaries using the manual method, it can affect time efficiency and data accuracy. By using a systematic calculation using a decision support system (DSS) that combines expert methods and SAW the resulting data can be used as an alternative to determine students who receive assistance to produce accurate data. In this case, the decision support system uses criteria, namely final semester grades, parental income, certificates, number of dependents and smart indonesia cards. This system is built on a web-based basis using the PHP programming language and Mysql database. The final result of this system can display ranking data and a combination of two methods. The resulting data can be printed in the form of a report. The resulting report can be used as a recommendation in the decision-making process regarding students who are entitled to receive educational assistance.

Abstract

Student aspirations are various demands that are packaged in students' creative ideas that propose a process of changing something. There is no aspiration complaint service system at the Fakultas Sains dan Teknologi, Universitas Islam Negeri Sumatera Utara. So that students do not have a place to express their aspirations. Along with the development of technology, a web-based student complaint application was made which is equipped with the AES (Advanced Encryption Standard) algorithm which is able to secure student aspiration messages so that the aspiration messages conveyed by students cannot be read by other students, so that student aspiration messages are more confidential. The design and manufacture of this web-based public complaint application uses the waterfall model. The waterfall model begins with the analysis stage, namely by analyzing and collecting data through interviews with students and the Administration of the Faculty of Science and Technology, the system design stage, namely by designing the system interface, the system coding stage, and this stage ends with the system testing stage. Carried out to determine the feasibility of the system.

Abstract

Many schools have implemented information systems that can make it easier for users to access the required data. However, SMPN 1 Percut Sei Tuan still uses manual methods to manage academic and non-academic data which causes the process of delivering academic and non-academic information there to not run optimally and lack of academic and non-academic communication between teachers and students. Based on this background, a school management information system was built as an effort to increase the effectiveness of academic and non-academic management at SMPN 1 Percut Sei Tuan.

Abstract

Research has been carried out on the effect of adhesive variations on the heating value of briquettes made from tea leaf powder. This study aims to determine the quality of the briquettes produced, this research is motivated by the increasing need for human fuel, so that researchers use tea leaf powder as the main ingredient in making briquettes. The variation of the sample used was tea leaf powder using adhesives in the form of tapioca, wheat flour and molasses as adhesives. With a ratio of 80%:20% and 70%:30%. The analysis carried out is the Calorific Value test. The results obtained from the Calorific value test of briquettes with the best quality approaching the quality standards of Indonesian briquettes were obtained in sample C2 with a composition (70%:30%) which resulted in a heat absorption value of 112.86 cal/gram.
