Abstract: Purpose: This study aims to analyse and develop design a heat exchanger (HE) for the production of Methyl Ethyl Ketone (MEK) which will be compiled into a computational program for the design of shell-tube type HE. 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.

Abstract: Purpose: This study aims to determine the results of the post-training evaluation (TPK orientation). Research Methodology: The research method used in this study is a quantitative method. The data used are primary data obtained from the results of questionnaires distributed to 152 respondents from 7 districts/cities in Lampung Province. 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. Contribution: The results of this study can be a reference for BKKBN Lampung Province in conducting appropriate training especially in accelerating stunting reduction through TPK orientation.

Abstract: Purpose: This study aims to evaluate pre-test and post-test results of participants in SIGA's new technical training for BKKBN representatives in Lampung. 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). Thus, the evaluation of education and training will obtain more comprehensive results. Contribution: The results of this study may be helpful to BKKBN Lampung for conducting proper training especially in evaluating learning outcomes. Keywords: 1. Training evaluation 2.

摘要:目的:本研究旨在评估SIGA对南榜BKKBN代表新技术培训参与者的前测和后测结果。研究方法:本研究采用的研究方法是定量方法。所使用的数据是从30名受访者的测试前和测试后分数中获得的原始数据。在此期间，使用的数据分析技术是描述性分析和配对t检验。结果:通过Wilcoxon match - pairs统计检验可知，前测和后测数据的显著性值(p值)为0.000(<0.05)。这表明，新Siga技术培训2022参与者的测试前和测试后结果存在统计学显著差异。因此，我们可以得出结论，参加2022年新标志技术培训后，参与者的知识在增加。局限性:为了进一步的研究，希望研究人员可以采取更多的样本，形成正态曲线。此外，如果全面实施Kirkpatrick评估模型，对教育培训实施的绩效(1级和2级)和培训后的评估(3级和4级)进行评估，将会得到更全面的教育培训评估结果。贡献:本研究的结果可能有助于南榜BKKBN进行适当的培训，特别是评估学习成果。关键词:1。2.培训评估前测后测分数
