Abstract

The used of electricity from year to year is increasing. One of the alternative to power plants with abundant availability is wood waste. The aims of this study is to: (1) design a wood waste PLTU prototype as an alternative biomass-based energy resource and an effort to reduce wood waste, (2) describe the calorific value, the resulting electrical voltage, and the duration of the lamp flame generated from wood waste fuel. Teak (Tectona grandis), surian wood waste (Toona sureni), and a mixture of both. This descriptive research includes 3 stages, which is analysis, design, and testing. Through this research, a prototype of a wood waste steam power plant was successfully designed by utilizing biomass waste fuel. The results showed that the calorific value, the resulting electrical voltage, and the resistance time of the lamp varied in the wood samples used. This indicates that the wood samples used have the potential to be used as an alternative to biomass-based energy resources.

Abstract

The human population increases every year, reported from the official website of the United Nation, in 2011 the world population reached 7 billion people. Then in 2016 reached 7.4 billion people and the world population in   2020 reached 7.7 billion people. It is estimated that by 2030 it will grow to 8.5 billion people and by 2050 to reach 9.7 billion inhabitants. which makes energy needs also increase. With these facts, we design gasification stove biomass energy that aims to reduce the use of non-renewable fuels.  The study aims to design a rice husks gasification stove to minimize agricultural waste. In this study, there is an innovation in tar reduction using dolomite as a catalyst. This research uses qualitative research methods that are presented descriptively. The gasification stove design is inspired by the oil stove with the addition of an iron pipe that serves as an oxygen supplier. The design of gasification stoves using rice husk as fuel was successfully carried out. This stove is proven to be one of the tools to maximize the potential of using rice husks as fuel. Finally, we hope that this research can continue to be refined in further studies to maximize the utilization of rice husk waste as renewable alternative energy.

Abstract

UV-visible (UV-Vis) spectroscopy is a powerful instrument for qualitative investigation and quantitative detection of pollutants in water. UV-Vis spectrophotometry is an analytical method using the concept of transmission of light in UV and Visible wavenumber. Generally, compounds can be identified using UV-Vis Spectrophotometry, based on the concept of light absorption, specifically for compounds with a chromophore group and an auxochrome group. Although the utilization of UV-Vis spectrum analysis has been well-documented, no information regarding detailed step-by-step measurement for examining detailed quantitative analysis, particularly in determining the concentration of an analyte in an aqueous solution sample. Here, this study explores the idea and application of UV-Vis technology in water quality detection, including guidelines for determining the concentration of the sample in an aqueous solution. To support the analysis, we also added practical examples for understanding concentration during the organic decomposition. This paper is intended to be useful for researchers and students in understanding UV-Vis spectrophotometry when analyzing chemical composition during chemical decomposition, photocatalysis, phytoremediation, and adsorption analysis.

Abstract

This paper contains guidelines and provides a basic understanding of how to do experiments in dye adsorption using carbon. This paper presents a step-by-step experimental procedure from carbon preparation (as biochar) from agricultural waste to concentration measurement using UV-Vis Spectroscopy. We used agricultural waste as a model due to its high cellulose and organic content, making it easily converted into carbon. This paper can be used as a guide for researchers and students in the fabrication of carbon from agricultural waste biomass easily and inexpensively for its application as an adsorbent in the batch adsorption process. This paper also supports the current issues in Sustainable Development Goals (SDGs).
