Abstract

Setiap proyek konstruksi, khususnya proyek peningkatan jalan terutama yang ada di Kabupaten Pulang Pisau, memiliki risiko yang harus dihadapi selama pelaksanaannya. Risiko pada proyek konstruksi khususnya proyek peningkatan jalan, tidak dapat dihilangkan tetapi dapat dikelola. Hal ini yang masih belum dapat dilakukan secara sistematik oleh para kontraktor yang ada di Kabupaten Pulang Pisau, khususnya karena belum ada model pengelolaan risiko pada proyek peningkatan jalan di kabupaten tersebut. Hal ini diperburuk dengan sedikitnya pengalaman pengelola proyek di kabupaten yang baru ini. Pengembangan model dengan menyediakan jenis-jenis risiko pelaksanaan konstruksi yang berpotensi terjadi di Kabupaten Pulang Pisau, serta dampak risiko maupun penanganan risiko. Dengan demikian implementasi yang sebenarnya dari langkah identifikasi dalam prakteknya manajemen risiko hanya perlu menggunakan pilihan-pilihan yang sudah disediakan. Pada model manajemen risiko pekerjaan peningkatan jalan di Kabupaten Pulang Pisau, risiko yang paling sering terjadi adalah risiko fluktuasi pedoman harga material/peralatan di lokasi setempat, yang berdampak pada kualitas pekerjaan buruk, kegagalan konstruksi, akan tetapi tingkat kerugian finansial masih dalam kategori kerugian sedang (kerugian berkisar 10 juta rupiah hingga 25 juta rupiah dari asumsi nilai kontrak 1 miliar rupiah), penanganan yang dianjurkan yaitu dengan adendum.

Abstract

The government of the South Kalimantan Province moved the provincial capital from Banjarmasin to Banjarbaru at the end of 2011. However, there has not been a clear decision as to what the government’s old building will be used for. One thing is clear, the utilization has to be optimized by considering the local government regulations. The aim of the research is to examine the highest and the best alternatives of utilization that can be adopted for such an asset. Non-probability sampling method was used in the research to find the alternatives. The alternatives were analyzed by using the highest and the best use analysis as the relevance test instrument for each of them. After analyzing the alternatives, the benefit-cost ratio (BCR) analysis was conducted to analyze the alternatives prior to determining their feasibility. Legal analysis, physical analysis, financial analysis, and the maximum productivity analysis were the stages conducted on the research based on highest and best use analysis. Based on the result of the research, the alternative which is feasible to do is that the building is used for other governmental or public purposes. Through the analysis, the alternative meets the criteria of the analysis as mentioned before with NPV Rp. 747,439,143 and BCR 1.024. Furthermore, according to 42.5 percent of the respondents, the building is best used for UPT offices and other institutions.

Abstract

Restriction on subsidized diesel fuel is advantageous because the government can save the state budget. However, it also causes problems of transportation. In Balangan there are only two gas stations that sell subsidized diesel fuel. This leads to queues of trucks on the road that reduce the road performance. This is important to study the influence of truck queues on the road around the gas stations. The objectives of this research are to obtain traffic characteristics that occur on these roads by using Greenshield, Greenberg and Underwood modeling and to determine the effects of trucks parked on the road on the level of service, as well as on the shock wave. Data were collected with a simulation on the national road segment of Mantimin-Paringin which is fourlane-two-way divided (4/2D) by parking zero unit to four units of trucks on one lane of the road. Based on the analysis, the best models for no, one, two, three and four units of trucks are, respectively, as follows: S = -0.541D + 55.58, S = -1.09D + 56.98, S = -1.25D + 58.02, S = -1.50D + 59.17, and S = -1.655D + 57.39. The maximum volume (Fc) decreases, and the value of the current jam density (Dj) and value of free flow speed (Sf) increase from zero unit to four units of trucks being parked. The more trucks were parked, the higher the degree of saturation (V/C) and the lower the level of service would be. The V/C was 0.028p3 - 0.039p2 + 0.208p + 0.292. The maximum number of trucks parked on the road was five units, with the distance between the truck being 1 meter. If nine units of trucks were parked, the highest degree of saturation (V/C) value was 1.013. It means the demand was bigger than the capacity of the road. It would cause a shock wave.

Abstract

The Public Work Service of North Barito Regency manages 46 units of heavy equipment comprising of 10 types, of which 9 are in good condition, 6 in fair condition and 31 are severely damaged. The lack of funding is often pointed out as the cause of minimum optimization of the heavy equipment management. To make matters worse, all the units are old and obsolete. This issue will burden the operation as well as the maintenance. Therefore, methods to optimize the heavy equipment asset are in demand, one of which is by looking for better management alternatives. This research aims to find alternative strategies in managing the heavy equipment assets of the Public Work Department of North Barito Regency, by analyzing their condition based on the technical aspects, funding, legality and management. This research uses descriptive analyses to portrait the existing condition of the heavy equipment management by the Public Work Service of Barito Utara Regency, the analyses of interest (expectation) and perception (reality) level, and SWOT analyses to formulate the strategy to optimize the management of the heavy equipment. Data collection was carried out in two phases, which is by direct observation, interview and questionnaire with respondents which include users/plant hire companies, and some public officials related the equipment management. Based on this research, the analysis of the interest level (expectation) and perception (reality) shows that the average level of perception is 2.52, and the average level of expectation is 3.44. This result indicates that the managers are still unable to provide a good service, and the users of heavy equipment have not received a satisfying service. Furthermore, the SWOT analysis generates S-O strategy (Aggressive) with 7 alternative strategies that attempt to use force to take advantage of existing opportunities. The alternative strategies are to utilize the functionality of workshops with various equipment activities recommended to support infrastructure, to improve service quality of heavy equipment with excellent service orientation, to utilize all available facilities, to empower human resources for the common good, and to develop an adjustment plan with potential targets revenue from the heavy equipment rental.
