Abstract

Livestock waste, such as bone, has always been ineffectively exploited. Bones contain organic compounds that can be further processed into usable products such as charcoal and activated charcoal. This research, therefore, aims to identify the optimum temperature conditions suitable for the manufacturing process of activated charcoal from goat bone waste using thermal activation. The study uses a two-stage process which is carbonization and thermal activation. Activation temperatures used in the process were at a temperature of 500 °C, 600 °C and 700 °C for three hours. The results of the characteristics of activated charcoal thermally produced in  this research met the Indonesian National Standard 06-3730-1995 about technical activated charcoal, and the  optimum conditions were at an activation temperature of 500 °C. These characteristics include the values of the water content at 1.210%, ash content at 2.034%, absorption of iodine 926 mg/g, volatile matter of 0.434% and fixed carbon of 96.616%.

Abstract

The Covid-19 pandemic has affected almost every aspect of life in the world, including education. The learning process, which was originally done face-to-face at school is diverted to the home using the online learning model. The inequality of the teacher's ability to utilize technology affects the achievement of this online learning goal. The ability of teachers to conduct online learning depends on knowledge and experience in online teaching before the Covid-19 pandemic. Objective: This study was conducted to expose information related to teachers’ experience toward online learning before the Covid-19 pandemic. Method: The study was carried out by implementing a descriptive quantitative method. The instrument used in this study was questionnaires distributed online using the Google Form application. The data were analyzed through the stages of data reduction, data interpretation, and conclusion drawing. Finding: The results showed that 75% of teachers stated that they already had basic knowledge about online learning before the Covid-19 pandemic. 45.80% of teachers said they obtained information about online learning through school-facilitated training while 16.70% gathered information about online learning before the Covid-19 pandemic from government-facilitated training, and 37.50% obtained information about online learning from independent learning. A total of 54.10% of teachers stated had conducted online learning before the Covid-19 pandemic. However, only 20.80% of them stated that online learning is very effective to be implemented. Conclusion: The readiness of teachers to implement online teaching-learning depends on their knowledge and experience related to online learning. Inadequate teaching training causes the lack of understanding of teachers towards the benefits of supported information technology-based learning media.
