Abstract

Pengembangan pariwisata di Indonesia memiliki potensi besar sebagai sumber pendapatan negara, terutama untuk daerah-daerah yang memiliki kekayaan alam dan budaya ‘tumpah ruah’. Pulau Bali adalah tujuan pariwisata paling eksotis di Indonesia karena memiliki sesuatu yang istimewa. Salah satu isu lingkungan di Bali adalah pencemaran air bersih yang disebabkan oleh meningkatnya pembangunan akomodasi pariwisata seperti salah satunya, yaitu hotel. Kerusakan pada lingkungan bisa terjadi apabila pembanguan yang dilakukan tidak memperhatikan aspek-aspek di sekitarnya seperti penggunaaan lahan yang efektif, hemat dalam penggunaan energi dan air serta pemilihanan material yang ramah lingkungan. Green Building dapat menjadi salah satu solusi di bidang konstruksi. GBCI membuat suatu perangkat penilaian yaitu Greenship Exisiting Building yang dibuat khusus untuk gedung yang sudah terbangun mengingat bahwa gedung existing yang menerapkan konsep Green Building di Indonesia masih sangat kurang. Sertifikasi Green Building pada gedung existing dapat dilakukan dengan cara menerapkan beberapa perubahan pada gedung tersebut agar menjadi lebih ramah lingkungan. Penelitian ini dilakukan untuk mengetahui persentase Green Building dengan perangkat penilaian Greenship Existing Building Versi 1.1 dan memberikan rekomendasi teknis sehingga Umalas Hotel & Residence dapat melakukan beberapa perubahan yang mengarah kepada penerapan konsep Green Building. Dari 40 kriteria kredit dengan poin maksimal 117, gedung Umalas Hotel & Residence memperoleh 54 poin. Persentase memenuhi kriteria Green Building sebesar 46% sehingga dapat dikategorikan dalam predikat Silver.

Abstract

Regional Economic growth of Bali province is not evenly distributed in each regency/city which could be due to the lack of connection and interaction between centre of economic activities. These conditions indicate the need of infrastructures and facilities that link the between two areas particulary road connecting North-South of Bali which has standards of capacity and accessibility. This paper analyses the economic aspects based on the existing economic developments using the cost-benefit analysis method. The economic benefits of road construction generally account for the direct benefit of road users in the form of savings on vehicle operating costs and the time value. Meanwhile, indirect benefit in the form of macroeconomic GRDP (Gross Regional Domestic Product) is included in this study. The study results are: (1). if the economic feasibility of a direct benefit on the interest rate of 12%, NPV = Rp 118.7 billion; BCR = 1.2 and IRR = 14.9%; (2) With the inclusion of GDP benefits of macro economic, the feasibility of this project is quite sensitive. This happened if the investment risk on the interest rate of 18%, 15% increase in costs and 15% decrease in benefit with the economic feasibility indicators NPV = Rp 146.09 billion; BCR = 1.24 and IRR = 18.9%.

Abstract

The rapidly growing in the development of construction project inIndonesia has brought a very powerful impact in the construction business. Therise of the development of construction business has led to tight competition forcontractors to win the tender. A model of Fair and Reasonable Markup (FARM) byFarid and Boyer in 1985 is used to determine the smallest markup value /minimum bid price that used by contractors to meet the return on investment /capital which is expected in the project. By using FARM models, contractors areexpected to determine a price that is competitive, but it still can generate sufficientprofits for the contractors as bidders. The study results in markup values rangingfrom 1.58% to 1.69% and the rate of return on investment expected by thecontractor is about 20% per year.

Abstract

Abstrak: Penerapan prinsip waktu adalah uang /time value of money dalam perhitungan nilai waktu  memberi dampak positif ekonomi secara umum. Prinsip metode ini adalah  memberi motivasi berupa biaya pengganti kepada kontraktor jika bisa mereduksi  waktu pelaksanaan konstruksi, sehingga dampak negatif semasa konstrusksi  bisa diperkecil. Di  Amerika penyertaan perhitungan faktor nilai waktu ini telah dicoba dan memberikan hasil yang sangat  signifikan.Penerapan dilakukan dengan menggunakan  metode bidding on cost/time dan insentif/disinsentif. Sampai saat ini penyertaan faktor nilai waktu dalam kontrak proyek konstruksi jalan di Indonesia belum pernah dilakukan. Studi ini meneliti kelayakan penyertaan perhitungan faktor nilai waktu  dalam kontrak  proyek konstruksi jalan   di Indonesia  ditinjau dari aspek teknis saja. Studi dilakukan dengan mengambil  kasus Proyek Peningkatan Jalan  dan Penggantian Jembatan Provinsi Bali pada suatu periode tahun anggaran. Metoda diskriptip dipergunakan dalam kajian yang dilengkapi uji satisitik  t-tes untuk melihat perbedaan antara nilai waktu terhadap nilai denda. Unsur dampak ekonomi negatif  eksternal  berupa kerugian pendapatan pelaku bisnis lokal sepanjang sisi  jalan turut disertakan dalam perhitungan.  Hasil analisa studi kasus  cara penetapan calon pemenang lelang dan denda harian akibat keterlambatan menyatakan bahwa ditinjau dari aspek teknis faktor nilai waktu  layak dipertimbangkan  penyertaannya dalam kontrak proyek konstruksi jalan di Indonesia.

Abstract

Three main objective in the constructing construction project thereare cost, time and quality. Cost and time have great relationship and depending oncethan the other. Some time in the field we founded nonconform between the duration ofcompletion in the contract with the realization. On the case studi of PembangunanStadion Olah Raga Buruan in Kecamatan Blahbatuh, Gianyar, the owner need thatproject be completed earlier than the agreement completion. The influence ofacceleration completion project with the project cost need to study.In this case the CPM (Critical Path Method) be used with compressed the duration ofactivities on the critical path and do time cost trade off analysis. The project costmeans is the total cost project. The total project cost are direct cost (material, workersand equipment) and indirect cost (the other direct cost).The outcome of analysis be founded that accelerate (crash) maximum 65 days done, sothe earliest completion by 265 days without total project cost added. The projectcompletion optimum be founded too, with project duration 316 days and project totalcost minimum amount Rp. 13.358.425.131,28, that’s below 0.55 % than project cost in contract. This phenomenon show that accelerate the duration completion project notalways be increasing the total project cost, because the duration of completion projectin the contract probably does not the optimum duration of completion.

Abstract

RISK MANAGEMENT DURING IMPLEMENTATION OF HOTEL CONSTRUCTION PROJECT AT SARBAGITA AREA ABSTRACT Construction project is an unique project and constrained by cost, quality and time. During construction project implementation, problems are frequently occur that affect toward cost, quality and time. Therefore according to such matter, it is considerably necessary to conduct research concerning risk management. Risk management include risk identification, risk analysis, risk acceptance distribution, risk mitigation and risk ownership. This research was conducted through interview with expert parties in hotel construction project implementation at Sarbagita (Denpasar, Badung, Gianyar, and Tabanan) region. This research aimed to identify and determine risk acceptance level, determine dominant risk, conduct mitigation action and risk ownership allocation. Total risks identified in this research were 37 risks that consist of 19 risks according to literature and 18 new finding risks. Dominant risk in this research were 28 risks, classified into 19 undesirable risks and 9 unacceptable risks. Both risks frequently occur in upper structure work. The most frequent risk sources occur in undesirable and unacceptable risks were technical risk. Technical risk in unacceptable risk were difference between picture and actual field, inaccurate scheduling, picture problems from planner and material specification discontinuation. Technical risk in undesirable risk were mainly tools mobilization delay, working hours limitation, quality and specification inconsistency and material discontinuation. Mitigation action mostly performed in technical risk were such as communication escalation between involved parties and organization structure improvement and project administration. Largest risk ownership allocation were in contractor side. These were due to contractor as the most responsible party in construction project implementation.

Abstract

The project implementation process from planning to implementation sometimes encounters problems ranging from cost, quality and time. In the implementation process, there are obstacles, namely the soil conditions in the image do not match the actual conditions and the architectural work undergoes a design change, because the previously planned floor plan does not match the desired function. These problems lead to the need for additional costs and additional time for project completion. This study aims to identify, assess risk acceptance to determine dominant risk, mitigate risk and determine risk ownership that will be obtained as a result of these problems. The study used a qualitative descriptive method. Data were collected by means of brainstorming, interviews, observations and questionnaires. Questionnaires were distributed to 28 respondents. The results show that there are 40 valid risk identifications. There are 10 unacceptable risks and 21 undesirable risks which include dominant risk and 9 acceptable risks that do not require mitigation measures. Mitigation is carried out with 3 types of actions, namely by reducing, transferring and holding risks. The dominant risk is unacceptable, namely the occurrence of design changes more than once. Mitigation is done by ensuring the design is approved by all parties involved or who have an interest in the design to be carried out such as the owner or management of the hospital so that the design is in accordance with the desired function so that there is no design change more than once. The allocation of ownership of the largest risk is the responsibility of the contractor, namely the risk of financial problems to the contractor. The dominant risk impact on the additional cost and time added to this work has a major impact on the technical and project aspects. The total amount of additional costs is Rp. 10,825.600.000,- and the total additional time is 117 days on the project.
