Abstract

The climate, weather, and rainfall conditions that occur in the Meteseh Village, Tembalang District, Semarang City, especially in the Bukit Kencana Jaya area, are quite high during the rainy season. As a result of housing developments that may not consider the problem of drainage properly, some places experience soil erosion. Based on the results of observations at the location, it was shown that there were several points of the water channel that were damaged. This condition can cause blockage or overflow of water when the intensity of rain increases due to disruption of the water channel. If a puddle occurs, it can become a breeding ground for mosquitoes that have the potential to cause disease. It is necessary to repair the water channel to restore its function of the water channel. The implementation method starts with a field survey, then socializes the repair and maintenance of waterways, and direct practice of repairing damaged waterways. The repair was carried out by replacing the base of the canal using a U-40 cm concrete pipe and plastering on the sides so that the water channel would not experience erosion and could function properly again.

Abstract

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. Meanwhile, after training, a post-test is carried out. The result was that 91% of students understood how to use MS Project software. From the evaluation results, it shows that there has been an increase in understanding and skills by 86%.

Abstract

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.

Abstract

The materials that are often used in the world of construction both in bridges, water structures, and buildings is concrete. The characteristic of concrete is that it is strong withstand compressive forces, but weak in resisting tensile forces. Therefore, it is necessary to improve the characteristics of the concrete. Improving the characteristics of the concrete can be done by applying a fiber mixture to the concrete. There are two types of fibers used as a concrete mixture, namely synthetic fibers and natural fibers. The research conducted was concrete using chicken feather waste fiber which was categorized as natural fiber with a fiber length of 3 cm, the grade of the concrete used was 20 MPa and the percentage of additional chicken feather waste was 0%, 1%, and 2% of the volume of concrete. The test is the compressive strength and flexural strength of the concrete using a specimen cylinder 15x30 cm and beam 15x15x60 cm. Each percentage of chicken feather waste that is used as a concrete mixture is 5 samples. From the test results, it was found that the concrete with the addition of 0% chicken feathers obtained an average compressive strength value of 200.78 kg/cm2, concrete with the addition of 1% chicken feather fiber, the compressive strength value increased to 215.09 kg/cm2 and concrete with the addition of chicken feather fiber 2 % has a compressive strength value of 197.54 kg/cm2. Meanwhile, the flexural strength values obtained were 24.00 kg/cm2, 23.03 kg/cm2, 21.08 kg/cm2 for the percentage of 0%, 1% and 2% fibers, respectively. This shows that the concrete with the addition of bristle fibers the chicken has decreased the compressive strength value when it has reached its optimum level. While the addition of the percentage of chicken feathers to the flexural strength value does not have much effect on the flexural strength of the concrete which tends to decrease. This is influenced by the characteristics of the chicken feathers which are difficult to bond with the concrete as well as being easy to absorb water, so that the concrete takes a longer time to dry after the maintenance of the concrete.

Abstract

Time management is one of the important factors in the successful implementation of construction projects because it is directly related to time efficiency, cost, and quality of work. In the Semarang Regency Disdikbudpora Hall Rehabilitation Project, the preparation of the implementation schedule is still not optimal due to the determination of the duration of work that has not considered the complexity and relationship between activities properly. This study aims to analyze the application of time management using the Critical Path Method (CPM) method to obtain a more effective project implementation duration and identify activities that are on the critical path. The research method used is a quantitative descriptive method by utilizing primary data in the form of field observations and secondary data in the form of time schedules, weekly reports, work drawings, and Cost Budget Plans (RAB). The analysis was carried out using the CPM method through forward pass, backward pass, and total float to determine the critical trajectory of the project. Data processing is done using Microsoft Excel and network visualization is created using AutoCAD. The results showed that the normal duration of project completion based on the CPM method is 54 working days, 3 days faster than the existing implementation schedule of 57 calendar days. Activities included in the critical path include preparatory work, certain earthworks and foundations, concrete work, wall pairing, floor and wall coverings, and painting work. Activities on critical lines have a total float value of zero, so delays in the work will affect the overall duration of project completion. Based on the results of the analysis, the application of the Critical Path Method (CPM) has proven to be effective in optimizing project scheduling because it is able to identify critical activities and accelerate project completion time. This method can be used as a reference in controlling the implementation time of construction projects to be more efficient and planned.

Abstract

Volume sampah meningkat seiring dengan kemajuan suatu daerah yang berakibat jumlah laju produksi sampah sering tidak sebanding dengan proses penangananya. Hal ini tidak terlepas dari kebiasaan serta perilaku masyarakat. Permasalahan sampah bukan lagi hanya masalah kebersihan lingkungan saja, tetapi menjadi masalah sosial yang dapat menimbulkan konflik seperti di Kelurahan Tlogosari Kulon Semarang. Salah satu penyelesaianya adalah dengan pembuatan lubang biopori. Manfaat biopori selain untuk resapan air juga sebagai tempat untuk menjadikan sampah organik menjadi pupuk, dengan demikian jumlah sampah oragnik yang ada dapat dikurangi dengan kegiatan ini. Akan tetapi masih banyak masyarakat yang belum dapat membuat biopori dan pupuk kompos dari sampah organik. Oleh karena itu, kegiatan ini mendorong pemahaman masyarakat dan budaya pengolahan sampah yang tepat guna untuk menjaga kelestarian lingkungan khususnya di wilayah Kelurahan Tlogosari Kulon. Hasil dari kegiatan pembuatan biopori tersebut adalah masyarakat merasa terbantukan dalam mengolah sampah organik serta mendapatkan manfaat dari pengolahan sampah tersebut.
