One of the components that play a vital role to the success of a construction project is construction prices, namely material prices, leasing and purchasing equipment prices, and construction wages. In the planning stage, the price used is the approximate price that will valid at the time of the project activities. At the implementing stage, the price used is the result of detailed estimates approaching real conditions at the time of the project activities. At the stage of monitoring and evaluation, the price will be reviewed to the conformity of the realization in the field, both the quantity and quality, further compared with employment contract. Research on the affecting factors of price construction materials is important. Furthermore, the affecting factors will be analyse to get a model approach for relevant price of construction materials. The construction material object in this research was timber. The study was conducted to obtain primary data and secondary data. Secondary data was performed to establish the factors that are predicted to affect the price of wood materials. Primary data were collected by distributing a questionnaire to 15 contractors in the city of Palangka Raya. Data obtained from the questionnaire and then analyzed by Severity Index (SI) for establishing the factors that affect the price of wood materal. Furthermore, the data were analyzed by the PLS model to obtain a model of approach to wood material prices. The study states there are several factors that affect the price of wood materials, namely economic factors, location factors, material resources factors, transport factors, and regulatory and government policies factors. Model approach to set the price of wood material by using PLS analysis showed that the material resources has an effect on the price of wood material, while the most dominant variable is the location factor.

Concrete paving block for flooring is widely used as a material for the road pavement on campus, offices, sidewalks, roads, parking areas and so forth. This may imply that the use of paving blocks are so complex, so the need increases due to the practicality of installation and maintenance. Various attempts were made in an effort to improve the quality as a result of market competition of the paving block. As an alternative to improve the quality is the addition of sawdust in the manufacture of paving blocks. The purpose of this study was to determine the wear and tear, porosity and compressive strength of paving blocks with the addition of sawdust. The method used is an experimental method. Therefore, the study was obtained through the compressive strength, porosity and wear resistance by comparing the paving block that use the sawdust and without sawdust. The results showed the effect of adding sawdust to the compressive strength of paving blocks. For 5% sawdust addition , the results of the compressive strength of paving blocks are relatively the same as the compressive strength of paving blocks 0 % sawdust. But for the addition of 10 % and 15% sawdust, the decrease the compressive strength of paving blocks increasing significantly. The effect of the addition of sawdust on porosity and wear resistance is the higher sawdust paving block composition is, the higher porosity and the lower the wear resistance of paving blocks will be.

The rapid development of information technology have a positive and negative impacts. In this case, the advantage with the advancement of information technology can be utilized to store a variety of undergraduate thesis work of students, especially in the Department of Vocational and Technology Education Unpar stored in digital form. By way of this paperless storage can save space and storage space. But on the other hand, it is easy to be copied by the less responsible student. One way to protect the authenticity of ownership of digital data is by using watermarking. Watermarking technique is the process of adding a permanent identification code into digital data. In this study , the focus was on how to make use of watermarking techniques in digital documents. Experiments conducted concluded that the use of space for storing watermark bits is very promising. Decoding or watermark embedding is done by inserting a watermark on each bit contained in the document space, while the watermark retrieval or decoding by taking every bit watermark of spaces contained in documents that have been inserted watermark.

Self-compacting concrete is a concrete variant that has the ability to condense itself, because the workability and flowability of the high concrete. There are many advantages obtained when a construction using SCC. However, the limited knowledge of the SCC makes this concrete variant is less used in construction work. Through experimental research methods in the laboratory, by making the SCC mixture using 20% dust stone and fly ash variation of 0%, 10%, 20%, and 30%, obtained results (1) the addition of fly ash composition on the concrete made the flowability of concrete increased; (2) along with the addition of a maximum of 30% FA, the higher the viscosity of concrete, which is indicated by the smaller the value of T500; (3) along with the addition of FA, the value of the passing ability of SCC (blocking ratio value increases) increased; (4) The results testing of the compressive strength of concrete age of 7 and 28 days showed an increase due to the addition of FA of 0%, 10%, 20%, and 30% in SCC concrete mix.

The physical activities in Central Kalimantan Province especially Palangka Raya in the recent years indicates a good development and is cathed by the construction entrepreneur as one of good business opportunities, one of which is ready-mix-concrete company which produce fresh concrete. With this company, the concreting of high building can be done faster with stable concrete quality. In the field, the use of ready mix concrete for high building is equipped with a concrete pump. Concrete pump is an equipment to pump concrete to concreting location, mainly to a location difficult to reach by mixer truck. With concrete pump, concreting can be done faster. However, its productivity depends on the distance and the height of the location, beside the concrete quality itself. The research on concrete pump productivity on the concreting of construction project in Palangka Raya aims to make a mathematic model that is able to predict the relationship between concrete pump productivity and distance and height of the location of concreting. The result shows that there is a strong relationship between productivity with horizontal concreting, which is modelled by the formula (a) Y = 0.642 â€“ 0.09 X1 + E, where Y = productivity (m3/min), X1 = distance (m), E = error; (b) Y = 0.628 - 0.09 X1 - 0.07 X2 + E, where Y = productivity (m3/min), X1 = distance (m), X2 = height (m), E = error

The production of high strength concrete using local materials, which are available in Surabaya and its surrounding area, that consider adequate slump so that the design is applicable in the project site, begin to be needed in the construction world. Through laboratory experiments, mix design using materials such as portland cement, silica fume, fly ash, coarse aggregate, fine aggregate, and also superplasticizer produces high strength concrete with cylinder compressive strength between 48 MPa â€“ 93 MPa at 28 days age. By utilizing multiple regression analysis for data processing, a mathematical model for the designing composition of high strength concrete is proposed. The most factor that influences the compressive strength of concrete is the composition of silica fume, followed by composition of portland cement, finally the composition of water and fly ash.
