Abstract

Desa Pecuk merupakan salah satu desa di Kecamatan Mijen Kabupaten Demak yang  saat ini tidak luput mengalami permasalahan sampah terutama sampah plastik yang semakin meningkat dan belum dikelola dengan baik. Selain permasalahan sampah, Desa Pecuk berdasarkan data yang ada juga dihadapkan pada pemrmasalahan pengelolaan air limbah. Langkah mereduksi atau pengurangan dampak negatif dari sampah plastik khususnya botol plastik bekas yaitu dengan mengembangkan berbagai jenis teknologi pemanfaatan botol plastik, diantaranya adalah penggunaan botol plastik sebagai media biofilter dalam pengolahan air limbah domestik. Terdapat penelitian terdahulu terkait pemanfaatan botol plastik sebagai biofilter. Botol plastik bekas dapat digunakan sebagai media biofilter dan memiliki kemampuan penyisihan TSS (total padatan tersuspensi), COD (jumlah oksigen yang diperlukan untuk mengurai seluruh bahan limbah yang terkandung dalam air)  dan BOD (oksigen yang diperlukan oleh mikroorganisme untuk mengoksidasi senyawa – senyawa kimia) yang baik. Studi tersebut dimanfaatkan dalam pemberdayaan masyarakat di Desa Pecuk melalui tahapan persiapan dan pelaksanaan. Sosialisasi dilakukan di Desa Pecuk Kecamatan Mijen Kabupaten Demak menggunakan sampel dan penjelasan tentang pentingnya pengelolaan sampah dan limbah, nilai guna botol plastik bekas sebagai biofilter septic tank serta diakhiri dengan diskusi antara tim pengabdian masyarakat dan warga Desa Pecuk. Melalui kegiatan sosialisasi ini dapat menambah wawasan dan pengetahuan warga tentang daur ulang sampah botol plastik melalui pembuatan biofilter tanki septic.Pecuk Village is one of the villages in Mijen District, Demak Regency which is currently experiencing waste problems, especially plastic waste, which is increasing and has not been managed well. Apart from the waste problem, Pecuk Village, based on existing data, is also faced with waste water management problems. Steps are being taken to decrease or mitigate the negative impact of plastic waste, particularly used plastic bottles, by creating various forms of technologies for using plastic bottles, such as the use of plastic bottles as biofilter material in household wastewater treatment. There has been previous study on the use of plastic bottles as biofilters. Used plastic bottles can be used as biofilter medium, removing TSS (total suspended solids), COD (the amount of oxygen needed to decompose all waste materials contained in water), and BOD (oxygen required by microorganisms to oxidize chemical compounds). Through the preparation and execution stages, this study was used to empower the people in Pecuk Village. The socialization took place in Pecuk Village, Mijen District, Demak Regency, and included samples and explanations about the importance of waste management, as well as the value of using used plastic bottles as septic tank biofilters. It concluded with a discussion between the community service team and Pecuk Village residents. Residents can gain more insight and understanding about recycling plastic bottle waste by creating septic tank biofilters through this outreach program.

Abstract

This study aims to analyze road users' perceptions of pedestrian facilities in the Pemuda Corridor (Lawang Sewu – Mall Paragon), Semarang City. Variables such as safety, comfort, accessibility, and infrastructure quality are the focus of this research. Data were collected through questionnaires with a sample of 400 people, field observations, and interviews. Field study results indicate that despite many positive aspects of the current pedestrian pathways in the Pemuda Corridor, there are still deficiencies that need improvement. Certain areas require additional zebra crossings and traffic lights to enhance safety. Furthermore, cleanliness and maintenance of the sidewalks in some spots are still suboptimal. Accessibility for people with disabilities also needs enhancement, as there are still obstacles such as vehicles and vendors occupying the pedestrian paths. The physical condition of the pedestrian pathways is generally good, but some areas require upgrades. These findings imply the need for municipal government intervention to improve the safety, comfort, and accessibility of pedestrian pathways through the addition of safety facilities, stricter enforcement of regulations, and regular maintenance programs. Involving the local community in the planning and management process of pedestrian pathways is also recommended to identify problems more effectively and develop solutions that meet community needs. With these steps, it is expected that pedestrian facilities in the Pemuda Corridor and other areas in Semarang City can be improved to create a safer, more comfortable, and inclusive environment for all pedestrians.

Abstract

Keling District, Jepara Regency conducted a landslide risk analysis to determine the area's susceptibility and develop workable mitigation solutions. The analytical procedure includes threat identification, vulnerability and capacity evaluation, and methodology-based risk determination. The data used were topography, soil and rock types, joints and faults, rainfall, land use, and the frequency of disasters. Landslide-prone areas were mapped, and contributing factors were evaluated through the application of the VCA (Vulnerability Capacity Analysis) matrix multiplication approach. The findings demonstrate that population growth, deforestation, clearance of additional land, excessive rainfall, erosion-prone soil and rock conditions, and uncontrolled human activities contribute to the likelihood of landslides in Keling District. Building landslide infrastructure, raising public awareness, and closely monitoring changes in land use are all advised mitigating techniques. This strategy's implementation is anticipated to lower the likelihood of landslides and improve readiness for potential natural disasters.

Abstract

ABSTRAKPerubahan dalam proyek konstruksi selama pelaksanaan tidak dapat dihindari, termasuk perubahan desain, material, durasi pekerjaan, dan keterlambatan pembayaran. Studi ini menganalisis faktor penyebab contract change order (CCO), dampaknya terhadap proyek Jalan Poros Karadiri, serta strategi mitigasi untuk mengurangi dampak terhadap biaya, mutu, dan waktu. Berbeda dari penelitian sebelumnya yang lebih berfokus pada faktor individual seperti desain atau administrasi, penelitian ini mengintegrasikan analisis SWOT untuk mengidentifikasi masalah CCO secara lebih komprehensif. Data diperoleh dari wawancara semi-terstruktur, kemudian dianalisis kuantitatif. Hasil penelitian menunjukkan bahwa penyebab utama CCO adalah desain yang kurang matang dari konsultan perencana, terutama dalam mempertimbangkan kondisi existing di lapangan. Akibatnya, biaya proyek meningkat 1,5%, terjadi keterlambatan 62,5%, dan kualitas administrasi proyek menurun 36% akibat denda keterlambatan. Temuan ini memberikan implikasi bagi pengelola proyek dan pemangku kebijakan. Untuk mengurangi risiko CCO, perlu dilakukan perencanaan lebih matang dengan evaluasi menyeluruh terhadap dokumen sebelum tender, serta pengawasan ketat dalam pelaksanaan proyek. Strategi ini diharapkan dapat meningkatkan efisiensi dan mengurangi dampak negatif CCO.Kata Kunci: Contract Change Order, proyek, konstruksi ABSTRACTChanges in construction projects during implementation are inevitable, including design modifications, material changes, work duration adjustments, and payment delays. This study analyzes the factors causing contract change orders (CCO), their impact on the Poros Karadiri Road project, and mitigation strategies to minimize their effects on cost, quality, and time. Unlike previous studies that focused more on individual factors such as design or administration, this research integrates SWOT analysis to comprehensively identify CCO issues. Data was obtained through semi-structured interviews and analyzed quantitatively. The findings indicate that the primary cause of CCO is the inadequate planning by design consultants, particularly in considering the existing field conditions. As a result, project costs increased by 1.5%, delays reached 62.5%, and project administrative quality declined by 36% due to late penalties. These findings have significant implications for project managers and policymakers. To reduce the risk of CCO, more thorough planning is required, including comprehensive document evaluation before the tender process, along with strict supervision during project execution. This strategy is expected to enhance efficiency and mitigate the negative impacts of CCO.Keywords: Contract Change Order, construction project, risk mitigation.

Abstract

Contingency cost estimation is essential for construction project management to anticipate cost uncertainty due to various risks. This study analyzes risk-based contingency cost estimation in the Bogor City Phase I wastewater network system project. The background of this research is based on the need for accurate cost planning to avoid budget overruns and ensure project sustainability. The study aims to identify risk factors that affect contingency costs, group risks based on their degree of influence, and build a more accurate estimation model using the Partial Least Squares-Structural Equation Modeling (PLS-SEM) approach. This study uses a mixed method, namely qualitative analysis through interviews and literature studies to identify risk factors and a quantitative approach by distributing questionnaires to project stakeholders. The data was analyzed using SPSS 25 and SmartPLS software to test the validity and reliability of the contingency cost estimation model. The study results show that the most significant risk in the pre-construction stage is licensing and design, while in the construction stage is procuring equipment/materials and force majeure factors. The highest contingency cost estimate is in the preconstruction stage, with a value of 11.02%. The study's conclusion confirms that risk mitigation in the early stages of the project is essential to reduce the impact of budget uncertainty. The implications of this study contribute to the management of construction projects by providing a more accurate risk-based contingency cost estimation model that can be used as a reference for stakeholders in planning and managing infrastructure projects.
