Abstract

One of the problems that occurs on projects in the areas of Highways Department of Public Works in Kapuas is the delay in project completion. Some projects even have a critical condition. This is due to the fact that resource needs of the project are not met. In fact, the data submitted by the contractors during the tender procees are actually sufficienty good. However, at the time of execution, some of the projects undertaken by the contractors, the winning bidder, undergo a critical conditions. Therefore, in order to prevent future projects from leading to a critical state, it is important to introduce an instrument of early warning procedure (early warning) as a useful input for decision makers.The goal of this research is to make a system of early warning for critical control conditions (pro-konkrit) so that future projects can be controlled and prevented from getting into critical conditions. This research was limited to the use of equipment, labor and money as well as the management contractor. The system is proposed to be used before the contract is signed. The system is expected to be an input for decision makers.The result of this study is a system that consists of components of the resources (including: tools, labor and capital), management components (including: data and information, work procedures, monitoring and action), component of the project (such as: employment data, components of the evaluator, and component output (critical/non critical). The results of testing the feasibility and value of users about the system of contract crisis procedure that gives an accurate information, easy to use, the user understand the output of system contract crisis procedure and the contract crisis procedure gives the advantage for users.

Abstract

Nowadays, the growth of the city and population of Palangka Raya as capital city and the center of governance of Central Kalimantan is fast enough, so it results a certain planology pattern and dependention of the edge part which expanding to downtown and center of the business that also results the accretion of townee journey then, thus require the transportation service to serve it. Transportation service that serving during the time is ‘mikrolet’ (microlight car). However, the ‘mikrolet’ in Palangka Raya city recently less enthused by society. It is influenced by performance level of ‘mikrolet’ which has been less maximal. Through the study based on Standard of World Bank and Letter of Decision of Director General of Land Transportation No. 687/DRJD/2002 and Pacific Consultan International (PCI) Method, a performance parameter that became the base in determining how the operational performance of city transport and then the amount of ideal vehicles to influence the scheduling of operational of the city transportation so that operators would get the earnings relatively equal could be analysed. The parameters of operational performance of public transportation ‘mikrolet’ were service frequency, passenger amount, vehicle speed, travel time, cycle time, headway, load factor and operating cost, however the most influencing parameters were vehicle speed, travel time, cycle time, and headway. The optimum number of vehicle requirement for each line was determined by regulated cycle time value divided by regular headway, so that 15 vehicles in line A obtained, 10 vehicles in line B obtained, 11 vehicles in line C obtained, 8 vehicles in line D obtained, 17 vehicles in line E obtained, and 14 vehicles in line F obtained. After a scheduling based on regular headway and regulated time travel and vehicle speed, the performances of operational and service of the public transport ‘mikrolet’ became more regular compared to non-scheduled.

Abstract

The research aims at analysing simultaneous projects scheduling based on the availability of construction sources of equipment owned by contractors. The research mainly discusses about how simultaneous projects schedule based on the availability of equipment owned is arranged. The approach used in this research is construction project schedule modelling where construction projects are carried out using a certain project management system. Based on the analysis result, it is obtained that the project schedule is arranged by employing precedent diagram. Project equipment transporting matrix is used as an alternative to schedule simultaneous projects. Both of these instruments provide information about the type of works, timetable, project location and project equipment arrangement. The project schedule is arranged based on job package and project location. For the first job package both the schedule and the equipment transporting arrangement are scheduled. In this job package, there are only five locations located in the same area. The second job package consists of nine scattered locations. As a result, a stricter schedule and equipment transporting arrangement are required. It is expected that this research can be used as a guide in analysing simultaneous project schedule so that good quality and efficiency can be acquired, at the same time loss and inefficiency can be minimised. Transporting equipment is an important aspect of the project that must be put into consideration. For future researches, it is expected that this research can be developed using research models which are more complex and accurate

Abstract

Soil in the sampling area undergoes drying-wetting cycle in therainy season and the dry season. This could make pore water in the soilto fluctuate so that the suction changes. The experiment used no.42 Whatman paper filter to measure suction and direct shear test to measure the shear strength.No. 42 Whatman paper filter was placed in the sample inside a pvc tube. It took three variatons of water content. The first variation was wetting variation. Sample was given water so that the water content increase to 25%, 30% and 35%. The second variation was drying variation. Sample was stored in a desicator filled silica gel, so that water content decreased to 15%, 10%, 5% and 0%. The third variation was wetting-drying variation. Sample at maximum water content (35%) was dried gradually so that water content decreased to 30%, 25%, 15%, 10%, 5% and 0%. This experiment indicates that increasing and decreasing suction results in the variation of the shear strength and the volume soil. Variation in the soil volume is the alteration of void ratio (e), degree of saturation (Sr) and water content (w). The result during the wetting procces or rainy season, the soil shear strength will decrease along with decreasing suction. In drying procces or dry season, the soil shear strength will increase along with increasing suction.

Abstract

Kinarum River which is located in Tabalong Regency has not been used for farming. There is a vast farming area in the Kinarum River Basin which still heavily depends on the water from rain. Water from the river is only used for irrigation in three villages, namely Kinarum village, Pengelak village and Marindi village, although it has the potential to irrigate a bigger area. To increase the potential and the area of farm fields in the Kinarum River Basin, Water Scale analysis was carried out, while the water availability calculated using Primary Debit Method. The water availability analysis was based on daily or monthly river debit in a period longer than a decade. By using rain spill connection mathematical model, the potential evapotranspiration was obtained. The chosen rain-debit connection models with a monthly interval were Mock and NRECA methods, which resulted in the Primary Debit (Q80). Water Scale analysis of Kinarum River Basin used the water availability as Input (I) and the need as Output (O). The water availability or the primary debit (Q80) per year based on Mock Method and NRECA Method is respectively 0.831 m3/s and 1.337 m3/s. Mock method gives the best approximation (0.822 m3/s ) for the historic debit. Hence, the primary debit (Q80) is 0.831 m3/s. EventhoughKinarum River Basin has irrigated 300 hectares of farming land, it still has a capacity to extend its irrigation area up to 1,060 hectares by applying optimal planting pattern 5 (namely rice-crops-crops)

Abstract

The strategic position of Palangka Raya Mall which is located on the corner of Great Roundabout in Palangkaraya city affects traffic flow on roundabout caused by trip attraction of Palangka Raya Mall. One indicator of the traffic congestion on roundabout is the decrease in the vehicle speed. This could be caused by the limited option of access to Palangka Raya Mall. Aims ofthisstudyaretoanalyzethe impact of traffic flow due to the trip attraction of Palangka Raya Mall, and to measure the roundabout performance in addressing traffic flow caused by trip attraction of Palangka Raya Mall. This research was carried out by collecting data of traffic flow volume, studying road geometry, and studying access to Palangka Raya Mall. The collected data is then analyzed using IHCM 1997 method, and adjusted to access design of Palangkaraya Mall. First access design is a modification of access to Palangkaraya Mall from Cilik Riwut Street. Second access design is a modification of access to Palangkaraya Mall from Kinibalu Street and Cilik Riwut Street. From the results of analysis carried out based on the daily peak hours, it is obtained that the degree of saturation (DS) value for existing condition is 0.809 on circulating roadway between Yos Sudarso Street and Kinibalu Street, with Level of Service (D). Degree of saturation (DS) value for first access design is 0.887 on circulating roadway between Kinibalu Street and Cilik Riwut Street, with Level of Service (D). Degree of saturation (DS) value for second access design is 0.723 on circulating roadway between Yos Sudarso Street and Kinibalu Street, with Level of Service (C).

Abstract

Agregat kasar sebagai lapisan perkerasan jalan merupakan suatu permasalahan yang perlu ditindaklanjuti agar pelaksanaan pekerjaan dapat berjalan efektif dan efisien. Umumnya agregat kasar didatangkan dari luar Kabupaten Lamandau yaitu Kabupaten Kotawaringin Barat bahkan didatangkan dari Pulau Jawa dengan jarak tempuh yang cukup jauh dari lokasi pekerjaan, sementara material lokal dengan deposit yang sangat banyak belum dimanfaatkan secara optimal. Tujuan dari penelitian ini untuk mendapatkan hasil yang optimal dan ekonomis sesuai dengan spesifikasi teknis yang berlaku dari komposisi agregat lokal dengan agregat Merak sehingga dapat digunakan sebagai lapis perkerasan jalan yang efisien dan efektif. Proses penelitian ini dilakukan di laboratorium dengan mengkombinasikan agregat eks Merak (BM) dan agregat lokal eks Nanga Bulik (AL) dengan variasi 100% AL - 0% BM, 80% AL - 20 % BM, 60% AL - 40% BM, 40% AL - 60% BM, 20% AL - 80% BM dan 0% AL - 100% BM. Pengujian dilakukan dengan metode Standar Nasional Indonesia (SNI) untuk jenis penelitian: abrasi agregat kasar, batas plastis, batas cair, gumpalan lempung dan butir-butir muda pecah dalam agregat, California Bearing Ratio (CBR), analisa saringan dan pemadatan standar/modified. Hasil analisa menunjukan bahwa agregat lokal eks Nanga Bulik memiliki nilai abrasi 44,002 persen sehingga tidak dapat digunakan sebagai Lapis Pondasi Atas, Lapis Pondasi Bawah dan Perkerasan Bahu Jalan. Pada kombinasi campuran (20% AL - 80% BM) dapat digunakan sebagai material konstruksi jalan untuk Lapis Pondasi Atas, Lapis Pondasi Bawah dan Perkerasan Bahu Jalan, (60% AL - 40% BM) dan (40% AL - 60% BM) dapat digunakan sebagai material konstruksi jalan untuk Lapis Pondasi Bawah dan Perkerasan Bahu Jalan, sedangkan pada kombinasi (80% AL - 20% BM) hanya dapat digunakan untuk Perkerasan Bahu Jalan. Hasil analisa dari segi biaya produksi terlihat dari analisa harga satuan masing-masing kombinasi terhadap harga satuan standar bahwa penggunaan agregat lokal eks Nanga Bulik yang dikombinasikan dengan agregat Merak pada komposisi (20% AL - 80% BM) dapat menekan biaya produksi per m3 maksimal sebesar 11,271 persen untuk Lapis Pondasi Atas, komposisi (40% AL - 60% BM) dapat menekan biaya produksi per m3 maksimal sebesar 23,044 persen untuk Lapis Pondasi Bawah, dan pada komposisi (20% AL - 80% BM) dapat menekan biaya produksi per m3 maksimal sebesar 26,560 persen untuk Perkerasan Bahu Jalan.
