Alat sistem proteksi peralatan listrik dari sambaran petir pada saluran distribusi kini sudah menggunakan surge arrester berbahan metal oxide varistor (MOV). Oleh sebab itu surge arrester harus memiliki ketahanan terhadap tegangan lebih. Uji residual voltage dilakukan terhadap surge arrester setelah melewati proses produksi untuk mengetahui tingkat ketahanan terhadap sambaran petir. Metode yang digunakan dalam penelitian ini adalah studi literatur dan observasi langsung. Dalam penelitian ini terdapat dua hasil pengujian residual voltage surge arrester, yaitu surge arrester yang memiliki ketahanan dan surge arrester yang meledak. Dimana pada surge arrester meledak hasilnya melebihi nilai standar pengujian. Grafik yang dihasilkan gelombang meledak digunakan memiliki bentuk yang tidak teratur setelah terbentuknya T2 (waktu puncak gelombang). Namun, meledaknya surge arrester dapat disebabkan oleh beberapa faktor salah satunya yakni mutu material yang digunakan.

Based on the latest data from the Serang Regency Central Statistics Agency in 2022, the Open Unemployment Rate (TPT) of Vocational High School (SMK) graduates is still relatively high compared to graduates of other levels of education, namely 12.87%. Apart from that, from the results of observations, there are still many vocational school students who still need to be ready for work. This is because the industrial internship program has not been able to optimize students' work readiness, students' work motivation still needs to be visible, and students' communication skills still need to be improved for their readiness to enter the world of work. This research seeks to determine the influence of industrial internship, work motivation, and communication skills on vocational school students' work readiness. This research uses a quantitative approach to answer the research hypothesis, which asks whether industrial internship, work motivation, and communication skills are positively correlated with vocational school students' work readiness. This research used a questionnaire distributed to 180 students in seven vocational schools in Serang Regency. This research proved that industrial internship, work motivation, and communication skills significantly influence work readiness (7%). For the conclusions and limitations of existing research, this research provides several suggestions for improving vocational school students' work readiness by paying more attention to the variables of industrial internship, work motivation, and communication skills.

This type of research and development aims to create designs and products for robotics training, as well as robotic training design feasibility through expert validation and eval-uation by respondents. Based on a survey of 49 people surveyed, 28.3% said they did not master the microcontroller material, 10.8% said they had learned it very well, and 17.4% said they didn't know. This suggests that a lower level of competence compared to the SKKNI makes robotics training necessary. A self-training model is used for this training. The study uses a branch version of the ADDIE development model, which is carried out in five stages: 1. analysis, 2. design, 3. development, 4. implementation, and 5. evaluation. This media produces starter kits and video learning, The ADDIE method is a research method that runs from the stage of analysis to its evaluation, the analysis researchers must know the gap of competence from students to industry, search for in-tuitive needs, make the need and the gap into the design of training until the last evalua-tion process, this is finally the reason why Addie is used in this research. Students of SMKN 1 Cilegon and students of Professional Education Electrical Engineering Universi-tas Sultan Ageng Tirtayasa were used in this research. The analytical techniques used are qualitative and quantitative descriptive analysis. Evaluation results from starter kits, learning videos, and learning materials are used to determine the level of eligibility for robotic training designs. The results of the starter kit evaluation showed that the media starter kit was in the category "Very Fit" with an average score of 40.7 with a range x>33. In the respondent assessment, it was known that the average rating of the nine-teen respondents was 60.3 with the range x >51, suggesting that the Arduino Uno R3 project-based robotic training design containing a starter kit, video learning modules, and learning materials belonged to the category of "Very Feasible." In other words, this robotics training deserves to be done.
