Abstract

Pembangunan bangunan gedung wajib dilaksanakan secara tertib administratif dan teknis untuk menjamin keandalan bangunan gedung tanpa menimbulkan dampak penting terhadap lingkungan. Keandalan bangunan gedung adalah kondisi keselamatan, kesehatan, kenyamanan, dan kemudahan yang memenuhi persyaratan teknis oleh kinerja bangunan gedung. Tingkat keandalan suatu bangunan dapat diketahui dengan melakukan penilaian terhadap kondisi struktur bangunan. Seiring berjalannya waktu, struktur bangunan dapat mengalami kerusakan dan menimbulkan risiko besar bagi pengguna bangunan. Untuk mengurangi risiko akibat kerusakan struktur maka perlu diketahui aspek-aspek yang dapat menyebabkan terjadinya kerusakan. Penilaian tingkat keandalan struktur beton dilakukan dengan menetapkan kriteria penilaian kerusakan beton pada bangunan gedung berdasarkan skala prioritas. Penilaian skala prioritas kriteria kerusakan pada struktur beton ditetapkan berdasarkan pendapat para ahli, sehingga penilaian bersifat deskriptif. Untuk mengantisipasi permasalahan tersebut maka penetapan skala prioritas dilakukan dengan pendekatan Fuzzy Logic untuk mewakili adanya ketidakpastian yang digabungkan dengan metode Analytic Hierarchy Process (AHP) sebagai alat pengambilan keputusan. Dalam  Hasil penelitian menunjukan kriteria, sub kriteria 1, dan sub kriteria 2 dengan skala prioritas tertinggi. Secara keseluruhan kriteria penilaian kerusakan beton dengan skala prioritas tertinggi adalah paparan dan korosi pada tulangan, penurunan tanah, dan dinding geser. Dapat diartikan pula bahwa kriteria dengan skala prioritas tertinggi merupakan aspek yang harus diperhatikan dalam perencanaan, pelaksanaan, dan pemeliharaan bangunan. Building construction must be executed in an orderly, administrative, and technical way to ensure the building’s reliability without causing any significant drawback to the environment. Building reliability is safety conditions, health, comfort, and ease that fulfill the technical terms from building performance. A building’s reliability rating can be identified by assessing the building structure condition. As time goes, building structure can experience damage and cause high risk for the building’s users. To reduce risk from structure damage, the aspects that can cause damage need to be identified. Concrete structure reliability rating assessment is done by determining concrete damage assessment criteria on building based on priority scale. Priority scale assessment on concrete structure is determined based on expert opinion, so the assessment is descriptive. To anticipate that problem, priority scale determination is done by using the Fuzzy Logic approach to represent uncertainty, which is combined with the Analytic Hierarchy Process (AHP) method as a decision making tool. In the research results are shown the criteria, sub criteria 1, and sub criteria 2 with high priority scale. As a wholethe concrete damage assessment criteria with the highest priority scale is exposure and corrosion on the reinforcement, land subsidence, and sliding wall. It can also be interpreted that the criteria with the highest priority scale are the aspects that have to be watched out for in building planning, implementation, and maintenance.

Abstract

Concrete damage on buildings can be interpreted as the presence of a change in the physical state of concrete. Damage can be in the form of change on the concrete surface or loss of concrete quality. To be able to identify the concrete damage condition on a building, inspection and assessment is required. Visual assessment is a method that can be a good first step to identifying the concrete damage condition on a building structure. Visual assessment is limited to concrete surface that can be accessed with visual senses. The goal of the research is to develop the concrete damage assessment method on a building visually that can be accepted by construction industry users in Indonesia with the Soft System Methodology (SSM) approach. Application of the SSM approach in this research uses the Root Definition component, CATWOE analysis, Rich Picture, and Conceptual Model. Result that is obtained from research, is the development concept for a visual method of building damage assessment, based on the seven steps according to SSM. Research results are in the form of a method that can identify and assess concrete damage while determining the concrete damage level on a building visually.

Abstract

Concrete quality degradation is a concrete quality downgrade from the perspective of concrete tension. Concrete quality degradation on concrete structure can happen either on new buildings (buildings that are still being constructed/in construction phase) or existing buildings (buildings that are already operational/in operational phase). The possible causes of concrete quality degradation on new buildings are, among others: incorrect implementation process such as readymix concrete quality that isn’t according to plan, lack of compacting, inadequate maintenance. Concrete quality degradation examination is done by examining concrete tension. On new buildings, one of the ways concrete tension can be identified is through test object examination. Concrete is a construction material that has a unique tension trait, where if it’s examined with a number of test objects, the value will spread around one particular average value. The value number depends on the field implementation perfection level. If the concrete tension of test object isn’t according to plan, installed concrete assessment with destructive and non destructive method can be performed. This research is done to identify the amount of concrete quality degradation on building structure based on tension value of concrete test object at the construction phase. Analysis results show the occurrence of a large concrete quality degradation, necessitating the determination of characteristics and categories until the worst possible concrete condition for concrete condition assessment needs.  AbstrakDegradasi mutu beton adalah penurunan kualitas beton dilihat dari kuat tekan beton. Degradasi mutu beton pada struktur beton dapat terjadi baik pada bangunan baru (bangunan yang sedang dibangun/tahap konstruksi) maupun bangunan existing (bangunan yang sudah beroperasi/tahap operasional). Penyebab degradasi mutu beton pada bangunan baru diantaranya ada bagian pada proses pelaksanaan yang kurang tepat seperti mutu beton readymix tidak sesuai rencana, kurangnya pemadatan, perawatan beton kurang baik. Pemeriksaan degradasi mutu beton dilakukan dengan memeriksa kuat tekan beton. Pada bangunan baru, kuat tekan beton dapat diketahui salah satunya melalui pengujian benda uji. Beton adalah suatu bahan konstruksi yang mempunyai sifat kekuatan tekan yang khas, yaitu apabila diperiksa dengan sejumlah besar benda uji, nilainya akan menyebar sekitar suatu nilai rata-rata tertentu. Besar atau kecil nilai bergantung pada tingkat kesempurnaan pelaksanaan di lapangan. Apabila kuat tekan beton dari benda uji tidak sesuai rencana maka dapat dilakukan pengujian beton terpasang dengan metode non destruktif dan destruktif.  Penelitian ini dilakukan untuk mengetahui besarnya degradasi mutu beton pada struktur bangunan gedung bertingkat berdasarkan nilai kekuatan tekan benda uji beton pada tahap konstruksi. Hasil analisis menunjukkan terjadi degradasi mutu beton yang besar, sehingga perlu ditetapkan karakteristik dan kategori sampai kondisi beton terburuk untuk kebutuhan penilaian kondisi beton.

Abstract

The building industry used for meetings, incentives, conventions, and exhibitions (MICE) is one of the industries that has high economic attractiveness for investors. Regulations and user requests for new buildings must meet environmentally friendly building standards. The GREENSHIP green building certification system is issued by the Green Building Council Indonesia. To obtain a platinum rating, a minimum total of 56 points requires additional investment costs but will result in operational cost savings. The purpose of this paper is to find out what factors influence the optimization of construction costs through value engineering to achieve a green building rating tool with optimum costs in MICE green building design. The findings show that energy is the most influential factor in obtaining platinum rating certification, so it requires value engineering to achieve optimal investment costs. The novelty of this research is that the selection of materials/machines and work methods for environmentally friendly concepts that save energy needs to be done from the start of design to achieve a payback period for the additional cost that can be returned in 3 years and 2 months. that is feasible for new investments, which can be a commitment for company owners to build MICE green buildings.

Abstract

Project delays in the construction sector often occur due to various factors, such as changes in work drawings by the developer, payment delays, and modifications to the Budget Plan (RAB) caused by additional work. This study employs a qualitative approach through interviews and document analysis to identify the factors contributing to project delays and their impact on cost estimation and project completion time. The analysis results indicate that project delays not only increase labor and material costs but also extend the overall project duration. The application of the earned value method reveals that the Cost Performance Index (CPI) is above 1, indicating that actual costs are lower than the planned budget. However, the Schedule Performance Index (SPI) in several weeks shows values below 1, signifying delays in project completion. The findings of this research emphasize the importance of better planning, enhanced coordination between the project team and the developer, and improvements in the payment approval process to prevent future delays. By implementing risk mitigation strategies and more effective project management, construction projects can be executed more efficiently and align with the established targets. Abstrak Keterlambatan proyek konstruksi sering kali terjadi akibat berbagai faktor, seperti perubahan gambar kerja dari pihak developer, keterlambatan pembayaran, serta perubahan volume Rencana Anggaran Biaya (RAB) yang disebabkan oleh adanya pekerjaan tambahan. Penelitian ini menggunakan pendekatan kualitatif dengan metode wawancara dan analisis dokumen untuk mengidentifikasi faktor penyebab keterlambatan serta dampaknya terhadap estimasi biaya dan waktu penyelesaian proyek. Hasil analisis menunjukkan bahwa keterlambatan proyek tidak hanya menyebabkan peningkatan biaya tenaga kerja dan material tetapi juga memperpanjang durasi penyelesaian pekerjaan secara keseluruhan. Penerapan metode earned value mengungkapkan bahwa nilai Cost Performance Index (CPI) berada di atas 1, yang menunjukkan bahwa biaya aktual lebih rendah dibandingkan anggaran yang direncanakan. Namun, Schedule Performance Index (SPI) dalam beberapa minggu menunjukkan angka di bawah 1, yang menandakan adanya keterlambatan dalam penyelesaian proyek. Temuan penelitian ini menekankan pentingnya perencanaan yang lebih matang, koordinasi yang lebih efektif antara tim proyek dan developer, serta perbaikan sistem persetujuan pembayaran guna mencegah keterlambatan di masa mendatang. Dengan menerapkan strategi mitigasi risiko dan manajemen proyek yang lebih baik, proyek konstruksi diharapkan dapat berjalan lebih efisien dan sesuai dengan target yang telah ditetapkan.
