Severe traffic congestions are often in Dewa Ruci Intersection. It leads to the Bali Provincial Government is forced to build an underpass at this intersection. The impact of construction will be add to the congestion becomes more severe that will take it during the project. To overcome, it is necessary to make the comparative method that have already used (secant pile) with precast method (sheet pile) is known relatively quickly and cheaply. However, this comparison should be followed up with a risk analysis that will happen with these methods. The results showed that sheet pile can accelerate 13.58 days or 5.21% and reduce Rp. 2,754,284,040.00 or 14.47% of secant pile method. The construction cost risk level of sheet pile is almost equal to secant pile but the construction time risk level of sheet pile is smaller than the secant pile.

Multiyear construction project is one of the riskiest project due to uncertainty and dynamic economic condition. In multi-years project, cost escalation is inevitable because during construction period various risk factors such as increasing of labor cost, materials cost, energy cost, and equipment cost will affect the costs of the projects. This paper proposes a model to estimate cost escalation based on System Dynamic (SD) approach. SD is used to represent correlation among risk factors influencing cost escalation and to calculate cost escalation during project period. Causal Loop Diagram (CLD) was made based on in-depth literature review and confirmed by the experts. To validate the model, 7 multi-years projects in Indonesia were used as case study. The result showed that the proposed model can accurately predict project cost escalation with an accuracy of 91.21%. Simulation of SD also showed that the change of scope of work, ambiguous contract condition, unpredictable conditions, project schedule delay, inflation, and extreme weather condition are the most influencing factor of cost escalation. Besides predicting cost escalation of project, this model can also be used as early warning system in multi-year projects environment.

Indonesia is one of the countries prone to earthquakes. One of the earthquake disasters that occurred several years ago hit Palu and Donggala on September 28, 2018. It caused severe damage to infrastructure. Therefore, it is necessary to evaluate buildings vulnerable to earthquakes as a form of prevention. One of the buildings in Jember, the dr. Soebandi hospital, experienced cracks in the walls during an earthquake measuring 6.0 on the Richter scale in Nusa Dua Bali on July 16, 2019. This study carried out the risk assessment of the vulnerability of buildings to earthquakes using the Rapid Visual Screening (RVS) method from FEMA P-154. RVS is a method to identify a building that is potentially vulnerable to earthquake hazards based on visual observations from the exterior and interior of the building. The results of the evaluation using the RVS method showed that the dr. Soebandi hospital is categorized as safe and not prone to earthquakes, with a potential vulnerability percentage of 0.0126%. Based on these results, the building does not require special treatment to anticipate earthquakes; however, maintaining the occupants' safety and extending the building's life requires routine maintenance.Â

Kecelakaan kerja di sektor konstruksi masih mendominasi dibanding industri lain. Hal ini berdampak terhadap program pemerintah dalam mewujudkan SDGs bidang ketenagakerjaan. Berbagai penelitian tentang K3 sudah dilakukan tetapi masih memiliki kelemahan yang harus disempurnakan agar dapat membantu menyelesaikan permasalahan K3. Salah satu metode yang diharapkan mampu menyelesaikan permasalahan ini adalah metode Fault Tree Analysis (FTA) karena metode ini selain dapat menentukan faktor penyebab kecelakaan juga dapat memperkirakan probabilitas kejadiannya. Pada penelitian ini menggunakan metode wawancara dan pengamatan serta pencatatan data K3 pada proyek konstruksi pekerjaan jalan. Variabel yang digunakan diperoleh dari studi literatur dan Job Safety Analysis (JSA) yang dikonfirmasi kepada responden serta hasil pengamatan di lapangan yaitu faktor manajemen K3, unsafe condition, dan unsafe action. Metode FTA berhasil memprediksi probabilitas kegagalan pelaksanaan K3 pada proyek tersebut sebesar 0.3323 dengan kontribusi terbesar diperoleh dari variabel unsafe condition diikuti faktor manajemen K3 dan unsafe action. Untuk membuktikan keandalan model ini dilakukan validasi terhadap luaran model FTA dengan mendeskripsikan data kecelakaan yang terekam baik kuantitas maupun kategorinya. Untuk mencari besaran kontribusi setiap variabel dilakukan skenario model dan diperoleh hasil bahwa unsafe condition memiliki kontribusi terbesar diikuti manajemen K3 dan unsafe action dengan nilai masing-masing 0.0624, 0.0593 dan 0.0468. Model FTA juga dapat dikembangkan menjadi konsep DSS dengan syarat dan ketentuan tertentu.

Proyek Apartemen Grand Shamaya Surabaya merupakan salah satu proyek gedung tinggi di Surabaya yang dibangun di atas lahan yang memiliki kondisi tanah yang buruk dan sempit serta berada di antara gedung tinggi yang berdekatan. Pada pekerjaan basemen gedung ini memerlukan metode pelaksanaan yang tepat karena metode pelaksanaan ini sangat berpengaruh terhadap ketercapaian tujuan proyek (biaya, mutu dan waktu). Oleh karena itu perlu adanya analisa yang mendalam dengan mempertimbangkan semua variabel yang berpengaruh dalam penentuan metode konstruksi. Salah satu metode yang dapat diaplikasikan untuk membantu dalam pengambilan keputusan metode konstruksi yang tepat adalah Metode Analytical Hierarchy Process (AHP). Metode ini memiliki kemampuan dalam menyusun skala prioritas (sebagai faktor bobot) dari variabel yang kompleks dan mudah diaplikasikan, sehingga metode ini dapat dijadikan alat untuk pengambilan keputusan penentuan metode konstruksi yang mudah dan cepat. Pengambilan data dilakukan melalui kuisioner dan indepth interview dengan responden yang memiliki kepakaran (pengetahuan, pengalaman, dan keterampilan yang baik dalam penyusunan metode konstruksi). Hasil penelitian menunjukkan bahwa metode AHP ini dapat disusun sebagai sistem pengambilan keputusan penentuan metode konstruksi pekerjaan basement dengan tepat. Bobot prioritas yang dihasilkan dari AHP dapat dijadikan parameter untuk menentukan nilai keputusan penentuan metode konstruksi berdasarkan ketersediaan sumber daya yang dimiliki pada proyek tersebut.

The provision of district infrastructure requires detailed planning in preparing programs and budgets to encourage the equitable distribution of human settlement infrastructure development. The government has issued guidelines for preparing the RPIJM to harmonize the development plan, spatial plan, and Strategic Development Area plan. However, many problems must be resolved and are not proportional to the APBD/APBN revenues; therefore, it is necessary to formulate an appropriate RPIJM to support sustainable development. In this study, the RPIJM preparation refers to (i) policy directions and infrastructure strategic plans as well as the region's existing conditions analysis; and (ii) the design of infrastructure development. The RPIJM preparation must be carried out prudently because it involves a large budget, program of the community essential activities in solving existing problems and in sustainable development, synchronized infrastructure development for local and national governments, and the risk of failure in the management of its implementation. The results of the RPIJM are a proposed plan for the financing of the human settlements development sector, which includes: (i) Residential Area Development; (ii) Building and Environmental Management; (iii) Development of Drinking Water Supply Systems; and (iv) development of residential environmental sanitation. Recommendations of the RPIJM are compiled in the memorandum of the medium term program in human settlements, which outlines scenarios for district development in the publoc work-human settlements sector, proposals for investment based on needs, achievement targets by regional development goals and objectives, mechanisms of funding, handling priority, and investment program implementation.Keywords: RPIJM, sustainable development, development program, development funding

Global warming is an issue that forms the basis for many sectors to determine the development direction. The leading cause of global warming is the emission of carbon dioxide gas as a greenhouse effect from human activities. An increase in population can lead to an increase in occupancy. The high intensity of land use turns out to have a direct or indirect impact on increasing the production of greenhouse gas emissions. There should be an alternative developer of housing development. Green Building Council Indonesia (GBCI), a green certification agency in Indonesia, issued a green concept assessment for the area, Greenship Neighborhood Version 1.0. This research aims to determine the Greenship rating of the site and determine what work is needed to increase the Greenship 1 (level) rating in the Graha Riski Harmoni Housing area and the costs that must be incurred. The assessment begins with the provision of secondary data in this device, the Greenship Neighborhood version 1.0 site plan, and the AHSP of Banyuwangi Regency in 2020. With interviews and field observations, measurement results use seven benchmarks: LEE, MAC, WMC, SWM, CWS, BAE, and IFD. Based on the analysis and assessment, the Graha Riski Harmoni Housing area gets a score of 27 or 22.13%, so it has not met the minimum green area limit according to GBCI. Residential areas require a minimum of six additional jobs to get a score of 45 or 36.88% to meet the minimum green area limit with a Bronze predicate. The need cost for a rating upgrade of Rp. 2,045,276,163 or if rounded to Rp. 2,046,000,000. ABSTRAK Pemanasan global merupakan isu yang menjadi landasan banyak sektor untuk menentukan arah pengembangan. Penyebab utama pemanasan global adalah emisi gas karbon dioksida sebagai efek rumah kaca dari aktifitas manusia. Peningkatan jumlah penduduk dapat mengakibatkan peningkatan akan hunian. Intensitas penggunaan lahan tinggi ternyata baik secara langsung maupun tidak langsung berdampak peningkatan produksi emisi gas rumah kaca. Seharusnya para pengembang memikirkan alternatif pengembangan perumahan. Green Building Council Indonesia (GBCI) sebagai lembaga sertifikasi konsep hijau di Indonesia mengeluarkan sebuah perangkat penilaian konsep hijau untuk kawasan yang disebut Greenship Neighborhood Version 1.0 . Tujuan dari penelitian ini adalah mengetahui peringkat Greenship kawasan dan mengetahui pekerjaan apa saja yang diperlukan untuk meningkatan peringkat Greenship 1 (level) pada kawasan Perumahan Graha Riski Harmoni beserta biaya yang harus dikeluarkan. Penilaian diawali dengan penyediaan data sekunder berupa perangkat penilaian Greenship Neighborhood version 1.0, site plan, dan AHSP Kabupaten Banyuwangi tahun 2020. Dengan metode wawancara dan observasi lapangan, hasil penilaian dapat diketahui menggunakan tujuh tolok ukur yaitu, LEE, MAC, WMC, SWM, CWS, BAE dan IFD. Berdasarkan analisis dan penilaian, kawasan Perumahan Graha Riski Harmoni mendapatkan nilai 27 atau 22,13% maka belum memenuhi batas minimum kawasan hijau menurut GBCI. Kawasan perumahan membutuhkan minimal enam pekerjaan tambahan untuk mendapatkan nilai 45 atau 36,88% agar memenuhi batas minimum kawasan hijau dengan predikat Bronze. Kebutuhan biaya untuk peningkatan peringkat sebesar Rp. 2.045.276.163 atau jika dibulatkan menjadi Rp. 2.046.000.000.

Grand Shamaya Apartment Building, 44 Floor Apartment, is one of the buildings using a dual system construction. The system includes shear walls and moment-bearing frames (columns and beams) that work side by side to support lateral to gravity loads (earthquake and wind loads). The maximum load shear wall or 75% of the lateral load (wind and earthquake), and the size of the shear wall required is relatively large because it must withstand shear forces and bending moments. More treatment is needed to overcome this problem, namely by modifying the building's structure and adding an outrigger system. The Outrigger System itself is a wall component that functions as a one-floor beam. From the preliminary design, the column design is 1300mm x 1850 mm; beam measuring 900mm x 600 mm; plate thickness of 200 mm; shear wall thickness of 450 mm and outrigger design measuring 600 mm x 2000 mm thick. Then install the Outrigger System with axis positions T1 N ', T1 M', T1 E ', and T1 D' on floors 40 and 44. After re-analysis using the outrigger system, the deviation between floors can show a smaller value than before the outrigger system was applied. P-Delta effect control shows that the P-Delta effect in two structural directions can be neglected or safe because the maximum stability value of the structure in the X and Y directions is less than 0.09091. The latter fulfills the drift control. This result is the maximum value among several models that have been executed.
