Abstract

Abstract ISO in the construction sector guarantees the company implements Quality Management System (QMS) consistently. But in reality, not all contractors in Indonesia have certificate and implement QMS ISO. So it is necessary to carry out a comparative of the contractors performance, who are ISO and non ISO certified especially on concrete work as more than 60% of construction projects in Indonesia use concrete. Questionnaires and interview were conducted at the three ISO and three non ISO contractors to determine the differences performance on concrete work. MS Excel 2007, SPSS for Windows Version 22.0, and logistic regression were employed to process the data. SWOT analyses were employed to create the strategies to improve construction company performance associated with the implementation of QMS ISO 9001: 2008. The questionnaires and t test result showed a better perfomance by contractors who have certification of QMS ISO 9001:2008 for the concrete work on the variable of operational, human resources, quality of concrete products, and customers than those who have no ISO certification. Logistic regression showed that the variable of operational in positive significant trend on the contractors performance for concrete work associated with the implementation of QMS ISO 9001: 2008. SWOT analyses result in completion of work according to the procedures, speed in decision making, integrated documentation and communication systems, good relation with sub contractors as the strength. Human resources are less prepared to implement ISO, the performances were not relevant to the quality target, and rework as the weaknesses. Customers and operating environment as the opportunities. Competitors and lack of government support as the threats.Keywords: QMS ISO 9001:2008, performance of ISO and non ISO contractors, logistic regression, SWOT.

Abstract

Abstrak Untuk menjelaskan nilai plastisitas dari tanah berbutir halus dengan pengaruh kandungan air yang berbeda beda telah diperkenalkan oleh Clayton dan Jokes (1978) salah satunya dengan cara satu titik Cassagrande yang bertujuan untuk mempercepat waktu pengujian karena hanya dibutuhkan satu kali pengukuran nilai kadar air, dimana alat yang digunakan sama dengan pengujian standar. Untuk menentukan koefisien plastisitas (K) diperlukan koefisien tan b, yang dalam persamaan merupakan fungsi eksponensial. Hasil dari contoh yang diuji pada ruas jalan awal dan akhir yaitu sepanjang ruas jalan Padangan-Bojonegoro kilometer +STA 33-100 sampai dengan +STA 33-112 menunjukkan harga tanb sebesar 0.086.Dengan membandingkan hasil ini terhadap apa yang terdapat didalam literatur, antara lain British standard (0.092) dan ASTM (0121), dijumpai perbedaan dalam prosentase antara 7% sampai dengan 41%, meskipun hal ini tidak memberi pengaruh yang cukup berarti pada nilai akhir koefisien plastisitas K. Kata kunci: lempung plastisitas tinggi, kadar air, batas Atterberg. Abstact An alternative testing procedure by using the same apparatus has been suggested by Clayton and Jukes (1978), known as Casagrande one-point method is expected can be eliminate the time consuming process, and other drawbacks.This method provides a quick means of determining the liquid limit of a soil, because only one moisture content measurement is needed. To determine the factor (K), it is need first to calculate the coefficient tanb as an exponential function in proposed formulas.For the samples taken from several bore hole locations along the East outer ring road, started and finished from Bunderan Waru and Tanjung Perak (Surabaya) respectively, it can be concluded through this study, the coefficient tanb are 0.086. With compare the results to the literature reports, for British and American soils, the values of the coefficient tanb are 0.092 and 0.121 respectively. However the differences of this result to the literature reports is in the range of 7% to 41%, this not too much influence the final results of factor (K).Keyword: High plasticity clay, water content, Atterberg limit.

Abstract

Jakarta, the capital and largest city in Indonesia, suffered severe flood year by year. The flooding was greatly contributed by high runoff in Ciliwung River, the main river flowing through Jakarta. In this paper, the attempt to simulate the flood in Ciliwung River using distributed hydrological model is presented. Precipitation reanalysis at spatial and temporal resolutions of one degree and one hour from Jaxa Global Rainfall Watch is used for evaluating the rainfall within the basin (376 km2). Understanding the characteristic of rainfall-runoff mechanisms is important as a lesson learnt for future flood disaster mitigation. The model used in this research is BTOPMC physically distributed hydrological model, which uses blockwise TOPMODEL for runoff generation and Muskingum-Cunge for routing. Terrain map of study area with 30 meters resolution is obtained from ASTER-GDEM. The runoff is simulated hourly in three points, i.e. Katulampa, Depok, and MT. Haryono, representing upstream, middle stream, and downstream outlets. Validation by comparison with observed discharge is done in both points. The results reveal that the model gives reasonable results in simulating flood events, showed by NSE and RMSE at Katulampa of 56.81% and 87.58 m3/s. This simulation is useful to estimate the amount and timing of flooding which is essential for further application in flood forecasting and disaster risk management. Some further improvements of the simulation scheme, including utilization of radar-rainfall, field survey, and future direction for flood forecasting and warning system development are also discussed.Keywords: Flood, Ciliwung, Jakarta, Hydrological Model

Abstract

Frequently, financial problem can be an abstacle to a contractor when constructing and project. For that reason, financial management needs an optimum cash flow determination. How to determine an optimum cash flow of 2 floor building X Malang in the area of 8,521.91 m2?The writer proposes a resource-use-management-based optimum cash flow determination which employs various payment systems of ?start?, ?prorated?, and ?end? derived from cost, material, and work resources. Besides, resources are allocated for the schedule of implementation budget to be able to get maximum profit. Calculation analyses were carried out through trial and error method on 3 resource payment systems which were tried out 9 times each. They also employed an alternation of resource allocation, if the result of cash flow planning to schedule of the initial implementation of the budget plan does not achieve optimum results. First step in determination is to plan an appropriate schedule budget implementation plan. Then the schedule was put into varied resource payment systems to produce the project cost, from which cash flow was made.The determination results in no optimum cash flow from 27 payment system schemes. Consequently, resource allocation is in need in the implementation of budget plan schedule to get a maximum profit of IDR 8,001,066,721.41.Keyword: schedule, cash flow, payment systems, profit
