Abstract

Indonesia merupakan negara kepulauan dengan luas 3.374.668 Km2 yang terdiri dari 13.466 pulau, denganpanjang garis pantai sepanjang ± 99.093 km (Badan Informasi Geospasial, 2015). Identifikasikan kebutuhan danpotensi perbaikan pantai dari kerusakan erosi, dilakukan dengan menilai kerusakan dengan mengunakan variabelutama seperti kemunduran garis pantai serta menentukan prioritas penangan dengan memperhatikan nilaiekonomis kawasan tersebut. Kebutuhan dan skema pembiayaan, serta sumber Pendanaan dengan membuat modelpembiayaan ditentukan oleh cashflow untuk menyatakan kelayakan kegiatan investasi dalam penanganankerusakan maupun konservasi kawasan pantai dengan menggunakan analisis sensifitas didapat nilai IRR 29,62%dengan discount rate 12% dengan B/C ratio 1,98 pada kondisi kehihangan nilai benefit ±75%. Keterbatasanpendanaan untuk pencapaia target pembangunan infrastruktur yang ditetapkan dalam RPJMN tahun 2015–2019,adanya selisih pendanaan (funding gap) sehingga alternatif pembiayaan melalui Kerjasama PemerintahSwasta(KPS)/PublicPrivate Partnership (PPPs) dapat dilakukan dalam penyediaan infrastruktur. Penyediaaninfrastruktur sosial dalam bidang pariwisata pada kawasan pantai terbuka yang tidak memberlakukan tarif dapatmengunakan Pembayaran Ketersediaan layanan (Availability Payment), namun jika dapat menarik tarif untuksystem pantai tertutup maka skema DBMF (Desain, Build, Finance, Maintain) dapat sebagai alternatif pembiayaanperbaikan dan konservasi pantai khususnya pada pantai di Pulau Bali.

Abstract

The purpose of this study was to evaluate the feasibility of the construction of feeder roads Kaur District-Bengkulu Province street section Tanjung Kemuning. Methods of data collection using the method of observation and documentation. Methods of data analysis using cost analysis which includes the costs of the project, saving the BOK (Vehicle Operation Costs), and travel time savings and economic feasibility analysis includes economic analysis and sensitivity analysis. The results showed that (1) the results of the technical analysis of road pavement structure includes (a) the type of road pavement construction consists of four (4) arrangement of layers, namely 1) the surface layer, thick 10 cm, layer forming material Crescent, 2) the base layer, thick 21 cm, broken gravel layer forming material which doused with liquid asphalt, 3)sub-base layer, thick 23 cm, layer-forming material mixtures of local soil with lime or portland cement, and 4) basic soil layer, thick 41 cm, layer-forming material local soil at the site of road construction projects are compacted; (b) the condition of the pavement include 1) the traffic planning and traffic growth rates, namely a) average growth rate of 4.5%, b) current peak hours is 48 SMP/day, c) LHR value, ie LHR at the beginning of the plan year is 1.200 SMP/day, d) value of LHRT, i.e LHR at the end of the plan for 1.948 SMP/day; 2) value of CBR is 2.423% and E of 36.345 Psi; 3) functional quantities of pavement systems include (a) value of Po is 4.0; (B) valu of Pt is 1.5; and (c) value of Pf is 2.0; 4) value of R is 95% and S is 0.35; and 5) value of SN is 3 cm, and (c) the strength of road construction are 1) value of s is 1.065, 2) value of d is 5 deflections, and 3) value of FK is 0.47% and (2) the analysis of costs consistof (a) the total project cost Rp.10.142.160.500,00, (b) savings BOK (Vehicle Operating Costs) of the three dominant types of vehicles passing through Tanjung Kemuning Street, ie passenger cars, truck/bus medium, and truck/bus large amount Rp.953.814.502,55 covering fixed costs and variable costs Rp.878.980.000,00 of Rp.74.834.502,55, and (c) saving travel time of 0.6hours. This means that with the construction of feeder roads Kaur District-Bengkulu province,road users can save travel time for 0.6 hours compared to pre-project or equal to Rp.572.288.701,53; (2) evaluation of the economic viability include (a) the economic analysis, the value of BCR with an interest rate of 10% at 1,490, the interest rate of 12% amounting to 1,487, and the rate of 15% at 1,482. All the BCR value greater than 1, NPV at 10% interest rate for Rp.5.068.189.644,36, interest rates on 12% of Rp.4.570.421.018,57, and a 15% interest rate for Rp.4.451.192.644,17 , and the value of EIRR of 15.41% and (b) the sensitivity analysis obtained values BC(Benefit-Cost) nothing is worth (-).

Abstract

Human resources are an important factor in the implementation of construction projects. This is because the role of human resources is very dominant where HR is the main driving force in construction project work, so the quality of human resources is a determining factor for the success of a project. The purpose of this study is to make a regression model equation that can be used to predict the stress factor of construction workers (consultants and contractors) of buildings on time and cost performance. This research method uses a survey, namely by distributing questionnaires to collect main data to obtain facts by taking samples from the population. The results showed that the stress factors for building construction workers (contractors) that affect time performance were that I was not confident with my work because I did not complete the task properly (X18) and there were no definite regulations from the company regarding the workforce career development process. work (X22).
