Information regarding the evaluation of reasoning skills related to online socio-scientific issues is still limited due to limited instruments. This research aims to determine the validity and reliability of an online socio-scientific issue-based critical reasoning instrument. Content validity was proven by the assessment method by five experts. Confirmatory factor analysis was carried out with the Lisrel 8.8 program to prove construct validity. Instrument testing was carried out on 145 grade 10 high school students. Convergent validity was determined through the Average Variance Extracted (AVE) calculation, and reliability was determined through Construct Reliability (CR). There are 12 items from four dimensions of critical reasoning based on online socio-scientific issues: (1) evaluating SSI information, (2) identifying SSI complexity, (3) checking the credibility of information sources, and (4) multiperspective. The results of the content validity test obtained the Aiken coefficient value in the valid category. Based on the analysis results, the GFI, RMSEA, and p-value of the instrument fit the model and have loading factors that meet the minimum criteria. In addition, the instrument meets convergent validity and internal consistency. Thus, it is concluded that the instrument is declared valid and reliable and can be used to measure critical reasoning based on online socio-scientific issues.

<p><em>After graduating, many vocational school students take part directly in the work. One of them is vocational school students majoring in construction who can immediately work in the world of construction or projects. In the implementation of construction, many work accidents occur which are caused by human factors, because of understanding of the dangers in construction projects. It was recorded by the Social Security Administering Agency (BPJS) for Employment that from January to November 2022 there have been 265,334 work accidents in Indonesia. Therefore, students need to be given education about Occupational Health and Safety (K3). The aim is for the graduate to always apply K3 during construction so that graduates do not experience work accidents. Education was carried out through the presentation of material about K3 by the USM PKM team and continued with a question and answer session. Participants were very enthusiastic about participating in educational activities. It was shown from a lack of participants who asked questions to the PKM team. Apart from that, the results showed that 81% of the students thought that the PKM material was in line with community needs and that the overall PKM activities provided benefits.</em></p>

<p><em>Vocational High School (SMK) graduates are prepared to be able to compete in the world of work. To be able to compete, vocational school graduates are expected to have hard skills and soft skills. Likewise, Sakti Gemolong Vocational School tries to provide skills to its students through training. The problem is that to fulfill this, SMK Sakti Gemolong must collaborate with other agencies. Seeing this, the Community Service Team tried to help by providing MS Project training. The aim is to increase knowledge and skills in using project scheduling software. The target is students of Class XI Sakti Gemolong Vocational School, Department of Construction and Property Business (BKP) in Sragen. Activities are carried out in two stages, namely problem identification (preliminary survey to find out the curriculum and competencies), problem-solving approach (using presentation techniques as a lecture method, demonstration and direct practice on the computer as well as evaluation to find out the level of absorption of the material). In carrying out Community Service activities, before training a pre-test is carried out. The results obtained were that 95% of students did not understand how to use MS Project software.
