Abstract

The implementation of a construction project is highly dependent on the availability of labor which is the main driving force in the planning stage until the realization of the project. Without labor, it is impossible to achieve the goals of the project itself. The workability of the workforce is usually called productivity. One thing closely related to labor productivity is the cost of project implementation. The higher the productivity, the smaller the possibility of excess/inflation of project implementation costs, and vice versa. Based on this, further research is needed to determine the factors influencing labor productivity in implementing small-scale construction projects in Bali. Problem-solving and data analysis in this study used the Analytical Hierarchy Process (AHP) method. The results of the study showed that the most influential factors in labor productivity in project implementation were labor skills in carrying out work in the field (14.5%), equipment used during work (12.8%), the physical condition of workers (11.4%), job and work instructions given by superiors (11.3%), time schedule or work implementation time (10.5%), coordination between workers (10.2%), worker discipline during work or project implementation (10.1%), available materials (9.9%), and the last was the workspace or space available in carrying  a job (9.4%).

Abstract

Construction project implementation planning is an important stage that aims to optimize time, cost, and quality of work. In the construction project of the Badung Regency KPU Office Building, implementation planning is very crucial considering the location of the project which is in a densely populated area, so that an appropriate and efficient implementation method is needed. The problems faced are how to prepare an implementation schedule, calculate resource requirements, and plan costs systematically so that the project can run according to plan. This study uses the Precedence Diagram Method (PDM) to prepare the project schedule and Microsoft Project as a visualization tool. In addition, an analysis of human resource needs, materials, and tools was carried out as well as the preparation of the Implementation Cost Plan (RBP) and Budget Plan (RAB). The results of the study show that implementation planning using the PDM method produces a structured and efficient project schedule. The total cost obtained from the RBP analysis results is IDR 4,159,270,327.34, while the RAB reaches IDR 4,623,397,141.26, with a cost difference of IDR 464,126,813.93. This research is expected to be a reference for planning the implementation of similar building construction projects, especially in the context of using the PDM method.

Abstract

ABSTRACT The construction phase is a stage that needs attention so that the main goal of producing a quality project can be achieved. In the construction phase, project managers should consider the positive and negative aspects that will occur in the next stage, the operational phase. The construction project is a job sector that has high risk compared to other sectors. The number of work accidents in Indonesia is quite high and continues to increase from previous years. the number of accidents in Indonesia continues to increase from 2007 to 2011. The number of work accidents in Indonesia in 2008 experienced the highest increase of 13.17%. While in 2011 the number of work accidents in Indonesia that the smallest increase is 0.79%. It indicates the risk of accidents in Indonesia is quite high. Cost of safety can be divided by other approaches that consist of cost prevention, inspection cost, and accident cost. If the security system is not valid or there is no safety program, usually the cost of prevention and inspection is not provided or available but small (less adequate), while the accident costs are great. prevention and inspection is sufficient, so as to reduce the cost of accidents to be small. Safety and work safety management system planning is a series of steps, hazard identification, risk assessment, risk control, and cost calculation of risk control. Based on this it becomes interesting to do an assessment of the estimated cost prevention (prevention cost) and inspection cost (K3) on the construction project. The results of the review on the construction project reviewed indicate that the costs required for prevention cost and inspection cost of work accidents amount to IDR 726,182,726.28 or 5.39% of the total contract value consisting of the cost of personal protective equipment amounting to IDR 585,780,486.28, the cost of occupational safety and health equipment of IDR 32,402,240.00 and the cost of personnel of occupational safety and health is IDR 108.000.000,00.

Abstract

Pura Luhur Andakasa merupakan salah satu pura Sad Kahyangan di Bali yang terletak di Kabupaten Karangasem, tepatnya di Banjar Pakel, Desa Gegelang, Kecamatan Manggis. Pura Luhur ini berada 200 meter di atas permukaan laut. Pura ini dicapai dalam jarak 42 km dari Universitas Warmadewa. Dalam perjalanan menuju pura luhur, kondisi jalan yang harus dilalui sangat curam dan sempit. Hal tersebut disebabkan oleh kemiringan jalan yang sangat ekstrim serta lebar jalan yang cukup sempit. Hal tersebut yang kemudian menjadi permasalahan yang dirasakan oleh pengempon pura serta pemedek saat mengendarai kendaraan dan berpapasan dengan kendaraan lainnya mengingat persembahyangan dilakukan dari dari satu titik ke titik lainnya. Berdasarkan permasalahan tersebut, pengempon Pura meminta bantuan dari tim PkM untuk menyelesaiakan permasalahan yang terjadi. Adapun solusi terkait permasalahan geometrik jalan yang ditawarkan antara lain: (1) perencanaan desain geometrik jalan sebagai alternatif untuk mengatasi permasalahan kemiringan jalan, (2) perhitungan galian dan timbunan dalam perencanaan desain geometrik jalan yang baru yang dituangkan dalam RAB. Penyelesaian masalah mitra menggunakan metode survey, pengukuran langsung dilapangan dan tahap FGD dengan pengempon pura langsung untuk membuat dan merencanakan desain perencanaan geomerik jalan. Hasil dari kegiatan PKM akan digunakan oleh pengempon Pura dalam rangka pengembangan dan pembuatan jalan baru menuju Pura Luhur Andakasa.

Abstract

Nusa Penida Island tourist attractions have exotic natural characteristics of beaches and hills. This potential is evenly distributed in the northern part of the coast and the southern part of Nusa Penida. The unavailability of tourist support facilities has an impact on the comfort and accessibility that is not optimal towards these tourist attractions. The picture can be seen on the Gamat Beach tourist attraction which is located in the western part of the coast of Nusa Penida. Gamat Beach is one of the diving spots in Nusa Penida which has the potential for the beauty of coral reefs and fish as a tourist attraction on the beach. Currently, tourists have access to Gamat Beach by sea and to access the beach, there are no supporting facilities or infrastructure. Therefore, it is very difficult for tourists to enjoy the beauty of Gamat Beach optimally. In addition, Gamat Beach began to be eroded by coastal waves and it was feared that the coastline with beach sand would be eliminated. The purpose of this activity is to produce a master plan for the arrangement of facilities at Gamat Beach tourist attraction in an effort to support tourist activities at the tourist attraction. The methods used in this service activity are mapping, conceptual, induction (design), and focus group discussion. The results of this service activity are in the form of a design of a master plan for the arrangement of Gamat Beach tourist objects.

Abstract

In this study, a re-planning of schedules and costs will be carried out on the Balimed Denpasar Hospital Building Development Project which aims to be a basis for decision making so that the project runs according to plan. The calculation results obtained a Schedule Performance Index (SPI) of 0,683 and a Cost Performance Index (CPI) of 1 which shows that the project implementation was completed late with the budget as planned. If the project performance at the time of reporting remains the same until the rest of the work is completed, then the amount of the Estimate All Cost (EAC) is IDR. 46.881.134.933,39, which is the same amount as planned. This shows that there is no additional cost, so the total cost of remaining work is IDR. 40.249.362.635,43. The implementation time increased by 183 days because the Estimate All Schedule (EAS) was longer, which was 723 days from the original plan of 540 days.
