Abstract

This study aims to analyze the quality of biobriquettes made from salak skin with starch adhesive. Biobriquettes are one of the alternative fuel solutions that are environmentally friendly and can reduce organic waste. The analysis method used in this study is qualitative analysis. Salak fruit produces waste in the form of salak skin which is brownish and slightly prickly, then the salak seeds have a very hard texture which is black and brown. Salak seeds have a very hard texture so they are suitable as a basic ingredient for making briquettes The research method includes:the preparation stage of raw material for salak skin, carbonization stage of salak skin, adhesive material preparation stage and biobriquette quality analysis. From the research results, it can be concluded that both biobriquette samples, namely sample A (without adhesive) and sample B (with adhesive) have met the requirements of SNI No. 01-6235-2000 concerning charcoal biobriquettes.

Abstract

This study aims to analyze the fixed carbon content and combustion rate of briquettes made from banana peel waste as a renewable energy alternative. The experimental method was used, involving key stages such as material preparation, carbonization process, briquette molding, and testing of fixed carbon content and combustion rate. The results showed that the fixed carbon content of the produced briquettes reached 87%, indicating good combustion quality and high energy storage capacity. Additionally, the combustion rate of the briquettes varied, with Sample A having a combustion rate of 0.017 grams/s and Sample B at 0.014 grams/s. This difference suggests that Sample B has a longer combustion duration. Thus, banana peel briquettes have the potential to be an efficient and environmentally friendly alternative fuel. Further research is needed to optimize the production process and enhance briquette efficiency.

Abstract

This study examines the role of Artificial Intelligence (AI) technology in enhancing students’ digital literacy skills in the Plant Taxonomy course. A descriptive quantitative approach was employed using a survey method involving 32 Biology Education students at Universitas HKBP Nommensen Pematangsiantar. Data were collected through a Likert-scale questionnaire measuring AI utilization and key aspects of digital literacy, including information access, critical evaluation, data analysis, and ethical awareness. The findings reveal that students responded positively to the integration of AI in learning. AI-based applications were perceived as effective in supporting plant identification, understanding complex morphological characteristics, accelerating access to scientific references, and improving classification accuracy. Most students also demonstrated the ability to critically interpret AI-generated results, compare them with manual field observations, and use digital technology responsibly. In addition, students reported an improvement in their overall digital literacy skills after using AI in learning. In conclusion, AI technology plays a significant role in supporting interactive learning and strengthening digital literacy skills in the Plant Taxonomy course, indicating its potential for broader integration in biology education.
