Abstract

The use of technology and information in the Industry 4.0 era has been widely used to extract information from textual data patterns. The development of technology and the availability of big data from various platforms can provide valuable insights and facilitate better decision making. In this study, we aim to extract information and obtain the main topics of public sentiment on electric vehicle batteries. The data source is obtained from the results of comments or tweets on X social media. A total of 1,302 texts were processed using text mining techniques in the orange data mining application. This technique consists of several stages of text processing, namely transformation, filtering and tokenisation. The results of the text processing are extracted by word cloud to find the characteristics of words that are often discussed by the community. Next, sentiment analysis is performed to find out people's opinions about electric vehicle batteries based on positive, negative and neutral categories. Finally, topic modelling is performed using LDA to identify the topics discussed in each sentiment category. The results showed that public opinion was divided into three categories: 37% positive, 42% neutral and 21% negative. A frequently discussed topic in relation to electric vehicle batteries is the word feature nickel. Topic modelling produces five main topic categories that are frequently discussed by the public.

Abstract

The production process of biogas, which utilizes anaerobic biological processes, not only results in biogas but also produces slurry in the form of microorganism waste over time. The increasing number of anaerobic microorganism processes presents challenges that make it inadvisable to directly dispose of this anaerobic microorganism waste into the environment, as it has the potential to be a pollutant. Environmental management efforts can involve utilizing this waste to create solid organic fertilizer. This is due to the fact that the waste contains essential nutrients for plants, including nitrogen (N), carbon (C), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), and zinc (Zn). Despite the presence of both macromolecular and micromolecular organic matter, the C-organic content of anaerobic microorganism waste exceeds the minimum standard for solid organic fertilizer C/N ratio of 25, with a value of 49.62. A variety of techniques may be employed to reduce the C-organic content of anaerobic microorganism waste, including aerobic composting. The objective of this research is to ascertain the C-organic (C) and nitrogen (N) content in the solid organic fertilizer produced and to gain insight into the influence of air flow rate (oxygen) (liters/minute) and composting time (days) on the quality of the solid organic fertilizer produced. The findings of the study indicate that an increase in composting time results in a reduction in the C/N ratio, with a stabilization observed during a seven-day composting period, exhibiting a C/N ratio value of 18.05. An increase in the air flow rate results in a notable reduction in the C/N ratio. The greatest reduction, amounting to 65.85%, was observed when an air flow rate of 8.5 L/minute was employed.

Abstract

One of the causes of global warming is the presence of carbon emissions in the atmosphere. Carbon emissions trapped in the atmosphere will cause the Earth's average temperature to rise. Therefore, it is necessary to calculate and map carbon footprints to anticipate the effects of global warming, one of which is in the city of Bogor. The energy sector is the sector that contributes 43.83% compared to other sectors. The calculation of the carbon footprint is based on IPCC formulas. Meanwhile, data collection is carried out through the distribution of questionnaires and direct interviews with the residents of Bogor City in 6 sub-districts. The calculated carbon footprint of the energy sector comes from residential activities, namely the use of fuel for cooking, fuel oil for motor vehicles and electricity used during 1 month. The results of the energy sector carbon footprint in Bogor City were then mapped at different levels using QGIS. The calculation of CO_2 emissions in Bogor City resulted in 2,244,809.6 tons/year and was dominated by North Bogor District as the largest contributor of CO_2 emissions.

Abstract

The International Research Centre (IRC) is one of the units in the IPA Poncol branch, which includes coagulation, flocculation, sedimentation, filtration and disinfection units with a capacity of 40 L/sec concrete building. Based on direct observation, the problem in the IRC unit is that the produced effluent is less than optimal, which is 29.4 l/sec, while the designed capacity of the IRC unit is 40 l/sec and does not match the existing process units in the IRC with the applicable design criteria. The cause of the sub-optimal discharge is due to a malfunctioning penstock in the flocculation unit, filter media that has not been replaced for a long time and some valves that have not been maintained. The design criteria that are not met by the IRC unit are the velocity gradient parameter multiplied by the retention time in the coagulation unit, the retention time in the flocculation and sedimentation unit and the backwash time in the filtration unit. The purpose of this study is to provide recommendations for the optimisation of the IRC process unit at Poncol Branch IPA. The method used is to analyse the existing conditions with applicable design criteria. The results of this study are to provide recommendations for the coagulation unit, namely the height of the inlet well to the coagulation basin, changes in the water level in compartment one of the flocculation unit, and changes in the volume of the sedimentation and filtration units.

Abstract

The water from Perumda must meet the current drinking water regulatory parameters, namely the Minister of Health Regulation No. 2 of 2023 on Drinking Water Quality Requirements. This research aims to test water parameters including temperature, pH, residual chlorine, E. coli, coliform and determine the optimum dose of disinfectant effort to eliminate E. coli and coliform bacteria in Perumda water in City X. The research method involves data analysis of water characteristic test results and laboratory scale experiments using 7 variations doses of sodium hypochlorite disinfectant ranging from 0.3 to 0.9 ppm. Research results show that temperature parameters can change because they are influenced by room temperature. pH parameter value increases with each additional dose of disinfectant with the highest value being 7.68. The residual chlorine parameter, a dose of 0.6 to 0.8 ppm, produces residual chlorine within the quality standard range, namely 0.2-0.5 mg/L. For E. coli and coliform parameters, a disinfectant dose of 0.6 to 0.9 ppm is able to reduce the E. coli and coliform content to the value of 0/100 mL. The conclusion of the research shows that the optimum dose for the elimination of E. coli and coliform bacteria is a dose of 0.6 ppm because it is able to eliminate bacteria with the lowest chlorine residue, namely 0.22 mg/L.

Abstract

The utilization of chemical pesticides will not be wholly absorbed by plants, resulting in the generation of residuals that are ultimately detrimental to the environment and public health. This research project was the impetus for the development of environmentally friendly pesticides. Its objective was to ascertain the adhesion of green pesticide formulations, their direct contact use, and the impact on plant microscopicity. This type of research is applied to the reformulation of green pesticides, with a particular focus on their adhesion and direct contact exposure to pests. This study employed a non-experimental design to elucidate the phenomenon of microscopic conditions in plants that had been sprayed with and without the use of green pesticides. The plant species utilized in this investigation were tomatoes, chilies, kale, and celery. The results of the green pesticide formulation, as determined by the stickiness of the pesticide in the good category, are reviewed based on the absence of pesticide droplets and the presence of a gloss on the morphology of the plant. Microscopic examinations revealed no discernible differences in the tomato, chili, and kale plants. However, the celery plants exhibited notable alterations, including the presence of chloroplast gaps and discoloration in specific regions, which were attributed to environmental factors (temperature) and the use of Span Tween. The tests demonstrated that the pesticide formulation is effective in repelling and killing the target pests, namely Plutella xylostella and Bemisia tabaci. It is imperative to develop formulations that will repel Aphis fabae and prevent damage to the leaf morphology of the plant.
