Methodology: The problem with this HE is that the temperature of 2-butanol is 30?C from the storage tank. While the HE reactor requires a temperature of 99.6?C, HE plays a role in increasing the temperature from 30?C to 99.6?C. To be more energy efficient, researchers used heat of the product, MEK. Which is where to exchange heat from the product to the reactants. The design of a shell-tube two-pass exchanger with a working fluid in the form of 2-butanol as a hot fluid with water as a cold fluid. The HE specification on the shell size for the pressure drop is 4.9959E-06 psia, while the tube size for the pressure drop is 2.6550E-04 psia. The effective value of 14%. Results: Thus, HE with shell and tube doesn’t meet the requirements and standards of TEMA. Although the shell and tube type of HE doesn’t conform to the criteria and standards specified in industrial applications, the analysis can be used as a learning tool for the design process, heme performance analysis, and operating mechanism of the HE. Limitations: This research is focused on developing HE designs for the production of MEK. Contribution: This research can provide a reference for designing HE in industrial development. Keywords: 1.

Research Methodology: The research method used in this study is a quantitative method.

Results: Data analysis was carried out descriptively using visualization in the form of diagrams and tables. From the results of the analysis, it is known that the knowledge of the respondents is quite good but still needs further exploration, especially on the material for using the Elsimil application. In addition, the implementation of the TPK orientation activities was in accordance with the planned TOR (Term of Reference). Meanwhile, from the follow-up aspect, the involvement of districts/cities in providing guidance to TPK is still not evenly distributed because several districts/cities have not carried out further guidance for TPK. Limitations: For further research, it is hoped that researchers can take a larger number of samples from 15 districts/ cities that the evaluation results will be more representative for future improvements.

Research methodology: The research method used in this study is the quantitative method. The data used is the primary data obtained from the pre- and post-test scores of 30 respondents. During this time, the data analysis techniques used were descriptive analysis and paired t-test. Results: Through the Wilcoxon Matched-Pairs statistical test, it is known that the significance value (p-value) for the pretest and posttest data is 0.000 (<0.05). This shows that there is a statistically significant difference between pre-test and post-test results for New Siga Technical Training 2022 participants. Therefore, we can conclude that the knowledge of the participants are increasing after participating in the 2022 New Siga Technical Training. Limitations: For further research, it is hoped that researchers can take a larger number of samples to form a normal curve. Moreover, it is better if the Kirkpatrick evaluation model is fully implemented, the evaluation of the performance of the education and training implementation (at level 1 and level 2) as well as post-training evaluation (level 3 and level 4).
