Abstract

A project is said to be successful if the project is able to be completed at a competitive cost, can be completed on time or even faster than the scheduled time, and with the achievement of quality. For this reason, a reliable project manager is needed, who knows what his duties are as a project leader and has the required competency requirements. The competence of a project manager can be measured in three ways, namely knowledge or knowledge, skills or expertise and attitude or attitude. The results of the Pearson Correlation analysis show that of the eleven independent variables, only six are correlated with project success, including Communication and Scope Management, Human Resource Management, Leadership and Project Management, Professionalism and Management Issues, Responsibilities, Dreams and Priorities. Simultaneously these six independent variables have a significant influence on the project success variable. This is evidenced from the results of the F test or multiple correlation test which shows that the value of Sig. 0.032 < 0.050. So it can be said that the competence of the project manager has a significant influence on the success of the project. The influence of a project manager's competence on the success of the project can be said to be not too large, this is evidenced in the Model Summaryb table, by looking at the Adjusted R Square value of 0.080. The six independent variables only have an effect of 8% on the variation (up and down) of project success, and for 92% it is influenced by other variables not included in this study.

Abstract

Road maintenance is carried out continuously throughout the year and carried out as soon as possible when the damage is not widespread. Road maintenance is managed directly by the PUPR Service for Roads and Bridges in Bantaeng Regency through routine maintenance based on self-management funds. The pavement identification benchmarks used include the condition of flexible pavement damage and district road pavement damage which are included in the low traffic category. This study aims to: (1). Identify the condition of road pavement damage in routine road maintenance activities in Bantaeng Regency. (2). Analyzing alternatives for routine maintenance of district roads with a self-managed system. Using the Bina Marga method and the Pavement Condition Index (PCI) method to identify the level of damage and handling in routine maintenance with a self-managed system. The result of the damage number of the Bina Marga method is 17 so that the value of the road condition is 6 with the type of damage to crocodile skin cracks. While the results of the priority value of 5 < 7 which states the condition of pavement damage are grouped in a routine maintenance program with a self-managed system. The results of the survey of the SDI value of 100 are grouped in a lightly damaged condition in the category of routine maintenance. The results of the identification of damage conditions using the PCI method obtained crocodile skin cracks, obesity, box cracks, hollows, subsidence, edge cracks, fillings, aggregate wear and holes. Alternative treatment requires a routine maintenance program that is carried out on a self-managed basis.

Abstract

Cashflow planning is inseparable from scheduling conditions which include EST (earliest start time) or the earliest project start time, LST (latest start time) or the slowest project start time, and the use of non-critical activity floats which are a combination of the two, where activities in the project is collected in the middle. Thus, it is necessary to conduct a study to further examine cash flow planning in a construction project to obtain an optimal cash flow concept, which in the end can obtain maximum profit. This study aims to [1] Optimal cash flow planning in order to obtain maximum profit, from the payment model without a down payment, scheduling conditions for EST, LST and Optimum Shift. [2] Optimal cash flow planning in order to obtain maximum profit, with 20% down payment and 30% down payment, scheduling conditions for EST, LST and Optimum Shift. [3] Get a Project Scheduling scenario that can generate optimal cash flow, in other words the cash flow that generates the greatest profit. The results showed that [1] Conditions Without Down Payment with Monthly Payments, resulted in 9.29% Profit, the largest Overdraft was Rp. 1,533,680,766.00 CV =+, SV=+. [2] Conditions with 20% down payment and payment terms according to progress, resulting in 9.29% Profit, the biggest Overdraft Rp 848,581,656.00 CV =+, SV=+. [3] For conditions with 30% down payment and payment according to the progress terms, it generates 9.29% Profit, the largest Overdraft is IDR 586,319,072.00CV =+ , SV=+. And [4] Downpayment can indirectly affect profits, if when an overdraft occurs, the contractor cannot have sufficient funds so that they have to borrow funds from a third party, resulting in fluctuating interest expenses.

Abstract

Swadaya ponds are located in Lamasi District, Luwu Regency, South Sulawesi Province with a total area of ​​384 hectares of ponds. The Swadaya pond drainage system consists of a carrier channel and a discharge channel with water sources for irrigating the pond area obtained from fresh water sources taken from the Central Minanga river and salt water sources taken directly from the sea (Teluk Bone). The simulation was carried out on the Swadaya pond channel in Luwu Regency with Unsteady conditions using the HEC-RAS 4.0 software (Hydrologic Engineering Center-River Analysis System) issued by the US Army Corps of Engineering. What is reviewed with various quantities of Q80 and Qmin annual discharges for upstream Boundary Conditions and for downstream conditions using the influence of tidal changes, this is to find out how big the hydraulic changes are in the Swadaya pond channel. From the simulation for the boundary conditions Q80 and Qmin shows that: The greater the discharge in the upstream channel conditions, the greater the discharge, velocity, and depth of flow in the channel. At high tide, the flow discharge from upstream (Central Minanga River) to the primary carrier channel is smaller than at low tide. Meanwhile, the discharge that enters the secondary channel is greater when the water is in high tide. As for the effect of the Manning coefficient on discharge, time and distance, the smaller the discharge (Qmin = 13.99 m3/s) in upstream conditions, the effect of high tide will be greater and the distance from downstream will be further (s = 2680.64 m) and the greater the discharge (Q80 = 21.37 m3/s) in the upstream, the smaller the influence of the tide and the closer the distance from the downstream (s = 2665.33 m). In order for the availability of water to meet the needs of pond water in the Swadaya pond channel, a trial and error test is carried out on the slope of the secondary and tertiary canals.

Abstract

Bitumen Asbuton as a type of natural asphalt extracted from which there are many deposits in Indonesia is an alternative that can be used to improve the performance of asphalt mixtures where asphalt concrete pavements often experience problems, namely not achieving the design life due to early damage and at the same time it is expected to be able to utilize materials local. The purpose of this study was to obtain the results of the optimization of the asphalt mixture asphalt Laston Lapis Aus (AC-WC) when used Asphalt Oil and the addition of Asbuton which varied 0%, 5%, 7% and 10% and to obtain the characteristics of the asphalt mixture asphalt mixture (AC) -WC) which uses limestone as coarse aggregate. The research procedure uses the experimental method by referring to the provisions, terms and procedures of SNI, Bina Marga, AASHTO, or other related organizations. Sources of data obtained from research results as primary data and secondary data obtained from other sources which are the results of research that has been done previously. For the mixture with the addition of Asbuton 0%, 5%,7% and 10%, the optimum value of asphalt content (KAO) is 6.2%. The stability values ​​are 2161 kg, 2257 kg, 2410 kg and 2371 kg. The VIM score is 4.26%; 4.69%; 4.82%; and 5.10%. The deformation values ​​are 1.4825 (0%) and 0.945 (7%). With the addition of Asbuton will increase the value of stability, and the value of VIM also increases and reduces the rate of deformation. A mixture that uses asbuton a lot shows a greater stability value and is more resistant to hot temperatures and reduces the rate of deformation of the mixture so that it is indicated that it can improve the performance of the mixture and increase the durability of the mixture.

Abstract

One of the most important urban infrastructure is clean water as well as basic human needs. Its use is not only limited to household needs but also for public, social and economic facilities. One way to obtain clean water is to use PDAM services. The Regional Drinking Water Company (PDAM) is a business entity that processes and serves the drinking water needs of the community. One of the problems that have and will arise in the management of clean water is that the ability of PDAMs as clean water providers is generally still limited both in terms of coverage and quality of service. This study aims to determine the economic and demographic characteristics of the population as well as the most dominant PDAM water use activity in households in Tamalate District. The desired quantity of water is to meet the standards of the needs of the metropolitan city. The desired continuity of flow is to meet 24 hours per day. The desired water quality is to meet the applicable standards of physical parameters. The results showed that based on field observations of the dominant economic characteristics, the highest activity was bathing, continuity and quality were still not effective because the quantity of water still did not meet all customer needs, continuity of flow still did not flow 24 hours per day for all customers, and still there are customers who complain about the quality of the clean water consumed in terms of turbidity, smell and taste.

Abstract

secara fisik kualitas Angkutan Kota jenis pete-pete di Kabupaten Bulukumba memang kurang memberikan kenyamanan, misalnya tempat duduk tidak terawat karena kurangnya masa perawatan dan pada umumnya sopir angkutan Kota membiarkan penumpang berdempet-dempetan sehingga penumpang merasa pengap dikarenakan tidak menggunakan AC. Pada awal pelayanannya Angkutan Kota (ANGKOTA) mendapat respon yang cukup baik dari masyarakat karena selain relatif mudah diperoleh, tarifnya juga murah jika dibandingkan angkutan kota lainnya. Namun kondisi ini ternyata semakin lama cenderung menurun jika dilihat secara visual. Teridentifikasi bahwa fisik kendaraan yang masih tetap seperti awal beroperasi menjadi penyebab kecenderungan tersebut. Permasalahan ini didekati dengan cara membandingkan antara tingkat pelayanan eksisting dengan standar yang ditetapkan Direktorat Jendral Perhubungan Darat melalui pedoman teknis penyelenggara angkutan penumpang umum diwilayah perkotaan dalam trayek tetap dan teratur, serta juga dengan membandingkan tingkat pelayanan eksisting dengan standar yang telah ditetapkan oleh World Bank yang tercantum dalam A World Bank Study (1986). Penelitian ini bersifat deskriptif dengan analisis kuantitatif merupakan jenis studi kasus dengan survey dan observasi langsung di lapangan guna mengetahui kondisi tingkat pelayanan dalam hal ini meningkatkan kemampuan untuk menginterpretasikan kinerja tingkat pelayanan angkutan umum trayek dalam Kota di Kabupaten Bulukumba. Hasil Penelitian Menunjukkan Informasi yang diperoleh dari masyarakat pengguna angkutan umum di Kabupaten Bulukumba terhadap pelayanan lewat kuesioner yang disebarkan diketahui hal-hal antara lain: (I)Pengguna didominasi oleh pelajar, maksud perjalanan untuk sekolah dengan frekwensi perjalanan setiap hari dan pengeluaran pengguna angkutan kota antara Rp. 5.000 – 10.000. (II) Persepsi pengguna terhadap kualitas Angkutan Kota, seperti: mudah mendapatkan, waktu tunggu yang relatif singkat dan tarif murah. (III) Secara keseluruhan tingkat pelayanan Angkutan Kota apabila mengacu pada standar yang ditetapkan oleh Departemen Perhubungan maupun dengan metode Sturgess mempunyai kinerja baik.
