Abstract

In building infrastructure, cost calculations are needed, organized in the form of a Budget Plan (RAB) according to government standards. The RAB provides an overview of the total cost required for building infrastructure or construction projects. Additionally, the RAB calculations can also determine the need for building materials, the number of workers required, and the duration of the project. This Community Service program aims to provide knowledge and new skills to the community on how to calculate the Budget Plan (RAB) for building both private homes and community infrastructure, such as meeting halls, neighborhood watch posts, water channels, and so on. The implementation method begins with interviews to assess understanding of creating an RAB, followed by socializing the benefits of making an RAB, training, and practical exercises on how to calculate the RAB. Subsequent steps include monitoring and evaluating the results of the calculations. This Community Service program equips the community with the skills to calculate the RAB for infrastructure development, better understand the volume of work calculations, determine material prices or unit prices for work, and prevent cost overruns during the construction phase.

Abstract

The implementation of Occupational Safety and Health (OSH) in small-scale construction projects remains a serious challenge, particularly in Semarang City. Workers in this sector generally do not have an adequate understanding of the importance of using Personal Protective Equipment (PPE) in supporting occupational safety. This community service activity aims to provide direct training and mentoring to small-scale construction workers to understand and apply OSH in their daily work activities. The implementation method involves an initial survey through interviews and field observations, followed by participatory training and mentoring in the practice of using PPE. The results of the activity show that after the training, workers' understanding and compliance with the use of PPE increased from 50% to 80%. However, some workers still require further mentoring to get used to implementing OSH consistently. This program is felt to have a positive impact in raising awareness that occupational safety is not just a formal obligation. Still, a basic need that protects oneself, is reflected in the results of the post-test questionnaire that 90% of participants expressed their desire to comply with and implement the OSH program.

Abstract

One way to utilize water resources is through the development of irrigation networks. Two common approaches to irrigation planning are the expansion method and the intensification method. Sambirejo Village is one of the areas with extensive land that can be used for rice cultivation. However, due to the large agricultural area, several paddy fields do not consistently receive a water supply from the existing irrigation network. Geographically, Sambirejo Village is located near both large and small rivers, which can be utilized as sources of irrigation water. The main issues faced by the local partners include a lack of understanding in planning irrigation channels to ensure optimal functionality. As a result, existing irrigation systems do not operate as intended, and the community has not yet been able to harness the full potential of the nearby water sources for irrigation purposes. To improve the availability of irrigation water in Sambirejo Village, the activity aimed to provide partners with knowledge on irrigation channel planning, as well as insights into watershed areas that can serve as water sources and the layout of rice fields to be irrigated. The implementation method involved providing explanations on how the irrigation system was designed to utilize gravity flow without pumps, and demonstrating the positive impacts of a properly functioning irrigation network. As a result of the activity, a priority area of approximately 1,200 meters was identified for irrigation channel planning. Technical planning documents were also prepared, including working drawings, channel dimensions, field measurement results, and a cost estimate (RAB), which can be used as a basis for proposing development programs funded by village budgets or related government agencies.

Abstract

The old bridge structure, are subjects that must be monitored in bridge maintenance. Bridge detection supervision is very necessary to determine structural deformation caused by normal operations or environmental impacts such as temperature, humidity and heavy vehicle loads. Monitoring the structure as a whole also needs to be carried out after extreme conditions occur, such as an earthquake. Research on structural dynamics analysis of steel frame bridge conditions to determine the behavior of the structure. Vibration data is read using a wireless sensor network or accelerometer. The vibration mode signal obtained is processed using Fast Fourier Transform (FFT) analysis via MATLAB software, which will produce a graph of the relationship between the frequency domain and the time domain. Through this graph, the dynamic characteristics of the bridge structure can be analyzed, with several variations in the condition of the bridge structure.
