Abstract

Waste management at the Jatibarang Landfill, Semarang, faces challenges due to incinerator exhaust gas emissions, potentially decreasing air quality, and posing health risks to surrounding communities. This community service program implemented a smoke washer (wet scrubber) adapted to the conditions of a simple incinerator. The activities included designing and fabricating the device, integrating electrical and control systems, providing operational training for partners (CV Dewa Nata Persada and Jatibarang Landfill), and conducting field testing of exhaust gas quality. The tested parameters consisted of particulate matter (PM), carbon monoxide (CO), and sulfur dioxide (SO₂), which were compared with the quality standards of the Ministry of Environment and Forestry Regulation No. P.70 of 2016. The measurement results indicated that all parameters were below the threshold limits, with pollutant concentrations decreasing from the initial operation to the following hours, signifying more stable performance of the device under steady-state operating conditions. These findings demonstrate the importance of the community service program in enhancing partners’ awareness and capacity in environmentally friendly waste management, underscoring the project's significant impact.

Abstract

Occupational Safety and Health (OSH) is a crucial aspect of land surveying practices conducted by vocational high school students. The risk of accidents, such as falls, being buried by soil, and exposure to extreme weather conditions, necessitates the optimal implementation of OSH awareness and compliance. This study aims to analyze the integration of student awareness and compliance with OSH in land surveying practices. The research employs a quantitative approach using multiple linear regression analysis. Prior to analysis, the data were tested for (1) normality, (2) homogeneity, and (3) linearity. The study population consists of 105 students from the Construction and Housing Engineering program at SMK Negeri 3 Semarang, selected through a total sampling technique. Data were collected through questionnaires, observations, and interviews, then analyzed using SPSS. The results indicate that student awareness and compliance significantly and simultaneously influence OSH implementation, contributing 78%. The correlation analysis reveals a strong relationship of 88% between the variables. Students with high awareness and compliance demonstrate greater discipline in adhering to OSH procedures in the field. These findings suggest that enhancing education, providing adequate safety facilities, and enforcing strict supervision can further improve OSH implementation in land surveying practices within vocational school environments.

Abstract

The Central Bureau of Statistics indicates that the open unemployment rate for vocational high school graduates remains one of the highest categories at 9.60%. In vocational education, particularly in the Design Modeling and Building Information program, this gap is also evident in the low preparedness of students in understanding the career paths available and the lack of strategies they have to enter the workforce. This study aims to analyze the role of career guidance in preparing vocational high school students for the workforce. The role of career guidance is focused on three main directions for vocational high school graduates: working in industry, continuing education to higher education, and entrepreneurship. This study uses a quantitative approach with a sample of 72 students from Vocational High School Negeri 3 Semarang, divided into two classes. The sampling technique used is total sampling. Data collection was conducted through work readiness and career guidance questionnaires, as well as interviews with instruments that were previously validated by experts. Data analysis included tests for normality, homogeneity, linearity, and simple linear regression. The results showed that career guidance plays a very significant role in the work readiness of students with a value of 68.8%. Meanwhile, the remaining 31.2% is influenced by other factors not explored in the study, such as motivation, interests, talents, and effort. This was supported by interview results, where students stated that career guidance helped them recognize their potential, explore job opportunities, and begin planning their next steps, whether for employment, continuing education, or entrepreneurship.

Abstract

Career decision-making challenges remain a critical issue in vocational education, particularly at the secondary level, where many students choose majors that do not align with their interests and abilities. This condition highlights the need for early career guidance to help students map their career paths and develop their competencies appropriately. This study aims to develop a vocational career guidance module for Social Work students; to determine the validity of the module based on expert evaluation; to analyze the validity and reliability of the test instruments; and to examine the effectiveness, efficiency, practicality, and implementability of the module. This research employed the ADDIE R&D model involving 60 tenth-grade students of SMK Negeri 5 Samarinda, divided into experimental and control groups. The results indicate that the module is highly feasible, with material expert validation at 94% and media expert validation at 91%. The test instrument demonstrates strong quality, with 30 of 33 items deemed valid and a Cronbach’s Alpha reliability of 0.925. The module is proven to be highly effective (91.6%), efficient (89.6%), and practical (93.8%), with an implementation rate of 86%. In addition, teacher and student responses reached 90.8% (excellent category). Statistical analysis confirms significant improvement in students’ career decision-making skills, with tcount = 13.396 > ttable = 2.002, Sig. = 0.000, and an N-gain score of 0.72964 (high category). These results show that the developed module effectively enhances the career decision-making skills of Social Work vocational students.
