Research on biomass conversion technology to obtain valuable chemical compounds continues to be carried out, one of which is the pyrolysis process. The pyrolysis process is very sensitive to the temperature and pressure of its operation. The reaction mechanism that occurs in a pyrolysis reactor is sometimes uneven so it takes longer to ensure all biomass particles are pyrolyzed. Experiments were carried out at various temperatures of pyrolysis reaction as well as catalytic and non-catalytic conditions to obtain the highest furfural products in the pyrolysis vapor. Using GC-MS analysis, the results show that the role of acid behavior in the ZSM-5 catalyst can increase furfural products and maximum furfural products obtained under pyrolysis condition at 500°C of 1.11 milligrams per gram of raw material for rice straw and increase to 1.48 milligrams per gram under catalytic pyrolysis condition.

ISO 14001 is a set of standards to help organizations for constructing an environmentally building or rooms. In the campus environment, the ISO 14001 is used as the guide for creating an environmentally laboratory. Based on this ISO, the environmental condition of the laboratory need to be checked periodically. Recently, IoT devices were developed as the tools to monitor the ecological status of the laboratory. However, the recent study of IoT-based monitoring is used only for collecting the data. The data is being processed manually on the server. In our research, we try to implement machine learning for the IoT-based monitoring tools to improve the performance and gives the capability to respond to any condition of the laboratory. In this paper, we discussed our proposed design of IoT-based monitoring devices. We used a microcontroller module called NodeMCU ESP8266 to build an efficient monitoring system. ESP8266 is a type of microcontroller board equipped with a WiFi module to make it possible to design a system that can send data from multiple sensors (temperature, humidity, light intensity, CO2 concentration) to be displayed and sent to the database server using the WiFi module. The data collected in the database will be processed using machine learning by the Classification and Regression Tree (CART) algorithm and then implemented to the microcontroller as embedded machine learning to detect impending early threats and provide early warnings. With this method, it has been found that the CART algorithm provides a speedy processing time with training and testing time of 0.5 seconds and 0.06 seconds, the precision of 0.999154, recall of 0.999946, and f1-score of 1.0. We also design our device to be compact to be placed anywhere inside the laboratory and consume low-power.
ISO 14001是一套帮助组织建造环境建筑或房间的标准。在校园环境中，ISO 14001被用作创建环境实验室的指南。根据此ISO，需要定期检查实验室的环境状况。最近，物联网设备被开发为监测实验室生态状况的工具。然而，最近对物联网监控的研究仅用于收集数据。服务器上正在手工处理数据。在我们的研究中，我们尝试为基于物联网的监控工具实施机器学习，以提高性能，并提供响应实验室任何条件的能力。在本文中，我们讨论了我们提出的基于物联网的监控设备设计。我们使用微控制器模块NodeMCU ESP8266来构建一个高效的监控系统。ESP8266是一种配备WiFi模块的微控制器板，可以设计一个系统，将多个传感器(温度、湿度、光照强度、二氧化碳浓度)的数据发送到数据库服务器，并通过WiFi模块进行显示。数据库中收集的数据将通过分类和回归树(CART)算法使用机器学习进行处理，然后作为嵌入式机器学习实现到微控制器中，以检测即将发生的早期威胁并提供早期预警。实验结果表明，CART算法具有较快的处理速度，训练时间为0.5秒，测试时间为0.06秒，准确率为0.999154，召回率为0.999946,f1-score为1.0。我们还设计了紧凑的设备，可以放置在实验室的任何地方，并且功耗低。
