Abstract

The pulp and paper industry continues to grow and produces large amounts of fly ash waste from the biomass combustion process. Alternative waste management besides landfills needs to be developed so that the use of fly ash can be ecologically and economically acceptable, such as for land applications in industrial plantations, especially on peat soils. This paper presents the results of the analysis of micro nutrients from fly ash from pulp and paper mill waste that can be used for agriculture and forestry. The elemental content of boron (B) and zinc (Zn) can be detected in fly ash samples both by lauryl amine extraction and stearyl amine extraction, where the optimum amount is obtained using 15 gram of fatty amine and n-hexane solvent with a processing time of 4 hours. Stearyl amine gives a higher yield than lauryl amine because it has a longer saturated carbon chain.

Abstract

The shortage of availability and increasing prices of Liquefied Natural Gas (LPG) encourage some people to use firewood as an alternative to traditional cooking fuel. The utilization of conventional stoves for combustion results in the generation of carbon monoxide (CO) emissions which can be dangerous to human health. Gasification stoves produce less CO emissions than conventional stoves and produce thermal efficiencies up to 35%. The shortage and high expense of LPG can be avoided by using biomass waste, such as twigs, wood chips, and palm fronds, as fuel for gasification stoves instead of kerosene or LPG. The gasification stove used in the socialization was designed based on the dimensions of the Champion Stove Top-Lit Up Draft. Wood logs that have been cut to a size of 6–9 cm and a width of 1 cm are utilized as fuel. 1.5 liters of water were successfully boiled for nine minutes by KOMAS gasification stoves. This socialization activities attracted the attention community of Batu Belah Village and at the end of this socialization, the team gave gasification stoves to the local community as an effort to apply the technology.

Abstract

Industry produces textile liquid waste which contains dangerous compounds such as methylene blue which can damage the environment. One effective method to overcome this problem is to use a TiO2 nanocomposite-based photocatalyst modified with Graphene Oxide (GO). GO is obtained from the synthesis of coconut shells, which is a biomass waste. This research aims to synthesize and display the performance of a TiO2/Graphene Oxide composite photocatalyst from coconut shells in degrading methylene blue. The TiO2/Graphene oxide nanocomposite synthesis method begins by carbonizing coconut shells to form graphite. Carbonization removes volatile compounds and produces a rich carbon structure, which is the initial requirement for the formation of GO. Synthesis of GO from graphite using the Hummer method. Synthesis of TiO2/Graphene oxide composite using a solvothermal process with various GO mass ratios. The performance of the photocatalyst was tested for degradation using methylene blue. Analysis of the TiO2/Graphene Oxide Composite using XRD, FTIR, SEM, BET characterisation and UV-Vis Spectrophotometer. The results show that at GO of 15%, the composite showed the highest surface area and optimal anatase crystallinity, resulting in the best degradation efficiency (70%). Graphene Oxide is synthesized from coconut shell biomass waste. This research shows that the TiO₂–Graphene Oxide composite has high efficiency in degrading dangerous synthetic dyes from textile industry wastewater through an efficient photocatalytic mechanism. This composite application is an application of technology that contributes directly to achieving the Sustainable Development Goals (SDGs), especially SDG 6 (Clean Water and Adequate Sanitation), through the development of sustainable, efficient and environmentally friendly waste processing technology.

Abstract

Environmental awareness and concern for cleanliness remain common challenges, not only in urban areas but also in rural communities. In Pangkalan Bunut Village, the issue of poor waste management persists, largely due to limited community awareness and the lack of adequate waste disposal facilities. To address this problem, our Community Service Team implemented a program to provide waste bins in the Pangkalan Bunut Market. This initiative aimed to encourage proper waste disposal practices, improve environmental awareness, and promote a clean and healthy environment. The program produced several positive outcomes: (1) increasing community understanding of the importance of waste management and environmental care; (2) providing accessible waste bins at the market to support cleaner surroundings; and (3) fostering behavioral change, as residents became more aware of the importance of proper waste disposal. This initiative is expected to serve as a model for sustaining cleanliness and environmental health in Pangkalan Bunut Village.
