Foundations are an important aspect of infrastructure development that ensures the safety and stability of building structures. Piles are one type of foundation that is often used in construction. As a construction company engaged in piling services, PT XYZ faces challenges related to dependence on third parties in supplying piles. In addition, the purchase and installation of piles that are increasing every year makes PT XYZ think it needs strategic steps to develop its business by entering the pile production sector. Decision making in developing the business needs to be carried out a feasibility study to find out whether the investment is feasible or not to run. In this study, investment assessment criteria are carried out on financial aspects. The method used to analyze the investment feasibility of PT XYZ is the Discounted Cash flow method which consists of calculating Net Present Value (NPV), Internal Rate Of Return (IRR), and Payback Period (PP). Based on the results of the analysis that has been carried out, it is obtained that the NPV value is Rp 7,998,226,761 (in accordance with the requirements if NPV>0 then the investment is feasible), IRR of 22.7852% (positive value greater than the discount factor of 10%), PP in year 4 (four). Thus it can be said that the business development investment to be carried out by PT XYZ provides benefits and is feasible to implement. Abstrak Fondasi merupakan aspek penting dalam pembangunan infrastruktur yang menjamin keamanan dan stabilitas struktur bangunan. Tiang pancang merupakan salah satu jenis fondasi yang sering digunakan dalam pembangunan. Sebagai perusahaan konstruksi yang bergerak dalam bidang jasa pemancangan, PT XYZ menghadapi tantangan terkait ketergantungan terhadap pihak ketiga dalam memasok tiang pancang. Selain itu, pembelian dan pemasangan tiang pancang yang semakin meningkat setiap tahunnya membuat PT XYZ berpikir perlu langkah strategis untuk mengembangkan usahanya dengan memasuki sektor produksi tiang pancang. Pengambilan keputusan dalam mengembangkan usahanya tersebut perlu dilakukan studi kelayakan untuk mengetahui apakah investasi tersebut layak atau tidak untuk dijalankan. Dalam penelitian ini, kriteria penilaian investasi dilakukan terhadap aspek finansial. Adapun metode yang digunakan untuk menganalisis kelayakan investasi perusahaan PT XYZ adalah metode Discounted Cash flow yang terdiri dari perhitungan Net Present Value (NPV), Internal Rate Of Return (IRR), dan Payback Period (PP). Berdasarkan hasil analisis yang telah dilakukan, diperoleh bahwa nilai NPV sebesar Rp 7.998.226.761 (sesuai dengan syarat jika NPV >0 maka investasi layak untuk dilakukan), IRR sebesar 22,7852% (bernilai positif lebih besar dari faktor diskonto sebesar 10%), Payback Period (PP) pada tahun ke- 4 (empat). Dengan demikian dapat dikatakan bahwa investasi pengembangan usaha yang akan dilakukan oleh PT XYZ memberikan keuntungan dan layak untuk dilaksanakan.

The development gap in eastern Indonesia has been the focus of the government's attention in recent times. Measures to equalize development have been implemented, including the establishment of three new provinces, including Central Papua Province with Nabire as its capital. This designation has had a significant positive impact in terms of increasing the Regional Budget (APBD) of Nabire city, especially in terms of road and bridge infrastructure development. In this context, PT XYZ as a road construction contractor, identifies business development opportunities through Asphalt Mixing Plant (AMP) investment with the aim of producing asphalt independently so as to reduce operational costs. Prior to decision making, a financial feasibility analysis needs to be conducted to evaluate the potential return on investment, along with an in-depth understanding of the risks. This research covers investment feasibility analysis, especially in the financial aspect using the discounted cash flow method. In addition, the addition of risk factors through Monte Carlo simulation is also carried out to obtain more accurate analysis results. The results show that the AMP investment by PT XYZ is considered feasible, characterized by a positive NPV and IRR that exceeds the MARR level. Furthermore, the risk of this investment can be categorized as low risk, because the Monte Carlo simulation results show a high level of confidence reaching 96.94%, namely the NPV> 0 and IRR> MARR values. Abstrak Kesenjangan pembangunan di wilayah timur Indonesia telah menjadi fokus perhatian pemerintah dalam kurun waktu terkini. Langkah-langkah pemerataan pembangunan telah diterapkan, termasuk penetapan tiga provinsi baru, di antaranya Provinsi Papua Tengah dengan Nabire sebagai ibukotanya. Penetapan ini telah memberikan dampak positif yang signifikan dari segi peningkatan Anggaran Pendapatan dan Belanja Daerah (APBD) kota Nabire, khususnya dalam hal pembangunan infrastruktur jalan dan jembatan. Dalam konteks ini, PT XYZ selaku kontraktor konstruksi jalan, mengidentifikasi peluang pengembangan usaha melalui investasi Asphalt Mixing Plant (AMP) dengan tujuan dapat memproduksi aspal secara mandiri sehingga dapat mengurangi biaya operasional. Sebelum pengambilan keputusan, analisis kelayakan finansial perlu dilakukan untuk mengevaluasi potensi hasil investasi, disertai dengan pemahaman mendalam terhadap faktor risiko. Penelitian ini mencakup analisis kelayakan investasi, terutama dalam aspek finansial dengan menggunakan metode discounted cash flow. Selain itu, penambahan faktor risiko melalui simulasi Monte Carlo juga dilakukan guna mendapatkan hasil analisis yang lebih akurat mendekati realitas. Hasil penelitian menunjukkan bahwa investasi AMP oleh PT XYZ dianggap layak, ditandai dengan NPV positif dan IRR yang melebihi tingkat MARR. Selanjutnya risiko investasi ini dapat dikategorikan sebagai risiko rendah, dikarenakan hasil simulasi Monte Carlo menunjukkan tingkat kepercayaan yang tinggi hingga mencapai 96,94%, yaitu nilai NPV > 0 dan IRR > MARR.

Abstrak Studi kelayakan investasi dilakukan dengan metode discounted cash flow (DCF). Hasil perhitungan dengan metode DCF disimulasikan dengan metode monte carlo. Indikator-indikator yang digunakan adalah tingkat okupansi, kenaikan biaya konstruksi, kenaikan biaya sewa dan service charge. Arus kas bangunan existing dan bangunan baru dibuat untuk menghitung nilai NPV dan IRRnya. Perhitungan metode DCF pada bangunan existing dengan nilai MARR sebesar 7,47%, didapatkan nilai NPV positif sebesar Rp.155.274.649.791 dan nilai IRR sebesar 31,5%, waktu pengembalian selama 6 tahun 4 bulan. Perhitungan bangunan baru didapatkan nilai NPV positif sebesar Rp.184.233.384.822 dan nilai IRR sebesar 17,5%, waktu pengembalian selama 8 tahun 8 bulan. Perbandingan perhitungan antara bangunan existing dan bangunan baru didapatkan nilai NPV positif sebesar Rp.28.958.735.031 dan nilai IRR sebesar 18,88%, waktu pengembalian 9 tahun 1 bulan. Hasil perhitungan dengan metode DCF dilakukan simulasi monte carlo, sehingga didapatkan nilai NPV rata-rata positif sebesar Rp.21.854.144.293 dan nilai IRR rata-rata sebesar sebesar 11,4% dengan waktu pengembalian rata-rata 8 tahun 11 bulan. Nilai standar deviasi untuk NPV sebesar Rp.6.457.269.316 dan nilai standar deviasi untuk IRR sebesar 1,34%. Perbandingan NPV positif dan nilai IRR lebih besar dari MARR, sehingga alternatif bangun baru layak dilaksanakan. Mempertahankan bangunan existing perlu dilakukan analisis teknik terkait keandalan bangunan existing. Kata kunci: studi kelayakan, metode DCF, metode monte carlo Abstract An investment feasibility study was conducted using the discounted cash flow (DCF) method. The results of the DCF method were simulated using the Monte Carlo method. The indicators used were occupancy rate, construction cost increases, rental cost increases, and service charge increases. Cash flows for existing and new buildings were created to calculate their NPV and IRR. The DCF method calculation for the existing building, with a MARR of 7.47%, resulted in a positive NPV of Rp.155,274,649,791 and an IRR of 31.5%, with a payback period of 6 years and 4 months. The calculation for the new building resulted in a positive NPV of Rp.184,233,384,822 and an IRR of 17.5%, with a payback period of 8 years and 8 months. The comparison between the existing and new buildings resulted in a positive NPV of Rp.28,958,735,031 and an IRR of 18.88%, with a payback period of 9 years and 1 month. The DCF method results were simulated using the Monte Carlo method, resulting in an average positive NPV of Rp.21,854,144,293 and an average IRR of 11.4% with an average payback period of 8 years and 11 months. The standard deviation for NPV is Rp.6,457,269,316 and for IRR is 1.34%. The positive NPV comparison and IRR value greater than the MARR indicate that the new building alternative is feasible. Maintaining the existing building requires a technical analysis related to its reliability. Keywords: feasibility study, DCF method, monte carlo method

This study analyses the investment feasibility of building Apartment X in Alam Sutera, Tangerang, by comparing two scenarios, namely direct apartment construction and gradual apartment construction, in the context of the impact of the Covid-19 pandemic. The methods used are Net Present Value (NPV) and Internal Rate of Return (IRR) to evaluate the potential benefits of both approaches. The data analysed includes development costs, sales of residential units, building operating costs, as well as revenue from environmental management fees (IPL) for residential areas and commercial shops, commercial shop rents and so on. The results show that the direct development scenario produces an NPV value of IDR 87,860,840,681 with an IRR value of 13.08%, while the phased development scenario produces a higher NPV value of IDR 112,893,521,357 with an IRR of 14.51%. Both scenarios fulfil the investment feasibility criteria because the resulting NPV value is greater than Rp 0, and the IRR value is also higher than the MARR set at 10%. Furthermore, investment in apartment X project is feasible to be implemented both directly and in stages, but gradual development provides more optimal and more profitable results compared to direct development. This study provides important insights for property developers in determining the right investment strategy in the post-pandemic economic conditions. Abstrak Penelitian ini menganalisis kelayakan investasi pembangunan Apartemen X di Alam Sutera, Tangerang, dengan membandingkan dua skenario yaitu pembangunan apartemen secara langsung dan pembangunan apartemen secara bertahap, dalam konteks dampak pandemi Covid-19. Metode yang digunakan adalah Net Present Value (NPV) dan Internal Rate of Return (IRR) untuk mengevaluasi potensi keuntungan dari kedua pendekatan. Data yang dianalisis mencakup biaya pembangunan, penjualan unit residensial, biaya operasional gedung, serta penerimaan dari iuran pengelolaan lingkungan (IPL) area residensial dan toko komersial, sewa toko komersial dan lain sebagainya. Hasil menunjukkan bahwa skenario pembangunan secara langsung menghasilkan nilai NPV sebesar Rp 87.860.840.681 dengan nilai IRR 13,08%, sedangkan skenario pembangunan secara bertahap menghasilkan nilai NPV yang lebih tinggi, yaitu Rp 112.893.521.357 dengan IRR 14,51%. Kedua skenario memenuhi kriteria kelayakan investasi karena nilai NPV yang dihasilkan lebih besar dari Rp 0, dan nilai IRR juga lebih tinggi daripada MARR yang ditetapkan sebesar 10%. Selanjutnya investasi pada proyek apartemen X layak untuk dilaksanakan baik secara langsung maupun bertahap, tetapi pembangunan bertahap memberikan hasil yang lebih optimal dan lebih menguntungkan dibandingkan dengan pembangunan secara langsung. Studi ini memberikan wawasan penting bagi pengembang properti dalam menentukan strategi investasi yang tepat dalam kondisi ekonomi pasca-pandemi.

Technological developments in the health sector, especially in surgery, have encouraged hospitals to adopt robotic-based operating systems. The use of robotic surgery provides clinical benefits such as increased precision, 3D visualization, and faster patient recovery. However, the adoption of this technology requires the support of significantly different operating room infrastructure compared to conventional operating rooms. This study aims to conduct a systematic review of the literature that compares the specifications of robotic and non-robotic operating room construction, focusing on design aspects, mechanical-electrical systems, and construction costs. The method used is Systematic Literature Review (SLR) based on the PRISMA protocol, with data sources from Scopus, ScienceDirect, PubMed, and Google Scholar databases. A total of 25 scientific articles that met the inclusion criteria were analyzed qualitatively. The results of the study showed that robotic operating rooms require a larger area (≥60 m²), Laminar Air Flow (LAF) ventilation systems, additional radiation protection, as well as more complex electrical systems such as HMI and UPS. In addition, the cost of building a robotic operating room is reportedly much higher compared to a non-robotic room. The study also identifies the limitations of the literature in Indonesia that discusses the technical planning of robotic operating rooms, thus providing opportunities for further research in the field of health facility design. The results of this study are expected to be a reference for hospitals, construction planners, and policymakers in developing advanced technology-based operating room infrastructure.
