Abstract:
One of the efforts in bridge maintenance is by conducting a preliminary assessment with a visual assessment. Growth in the number of vehicles each time will result in a risk of decreasing the capacity of the bridge and its age. Post-construction and maintenance is also a major requirement in infrastructure. This is often ruled out causing the bridge's function and performance to decline and ultimately cause damage. Siliti Bridge is a concrete bridge located in North Bungku Morowali, Sulawesi Tengah. This bridge gets special attention due to quite severe conditions. The purpose of the inspection on the Siliti Bridge is to get its condition visually and determine the estimated age of the remaining bridge which will be capital for further inspection. Bridge Management System (BMS) is a system of assesment to know the existing condition of each element of the bridge. The condition value of the bridge is needed to calculate its remaining life. Based on evaluations conducted in 2017, the value of the Siliti Bridge using the BMS standard is 3 (Damaged). The remaining age of the Siliti Bridge is 8 years.

Abstract:
Pavement planning is good, because in this way the pavement construction is able to carry the load of vehicles passing on it and spread the load to the layers beneath it, including the subgrade, without causing significant damage to the road construction itself. The purpose of this study is to obtain the most efficient alternative pavement thickness index and to obtain the required cost and time. The results showed that the Pavement Thickness Index (ITP) using the Bina Marga Method = 7.48 and the 1993 AASHTO Method = 10.20 had a difference of 2.72. The difference in Pavement Thickness Index (ITP) resulted in the addition of pavement thickness using the 1993 AASHTO Method. The economical Pavement Thickness Index (ITP) was the ITP Bina Marga Method with a construction cost of Rp 12.7 billion, with savings of Rp 3.8 billion. By determining the pavement thickness at the same base layer = 20 cm, it is found that the type of material is Aggregate Class B, CBR is 80% cheaper than cement + CTRB with savings of Rp 913,991,544, - ~ 1 billion. The time required in implementing the Bina Marga Method is more efficient than the 1993 AASHTO Method with a savings of 44 days, this is due to cement work + CTRB = 15 + 29 = 44 days. While Aggregate Class B, CBR 80% only takes 22 days, thus saving 22 is also due to the larger ITP of the 1993 AASHTO Method so that it requires additional thickness of the base layer under Aggregate Class C, CBR 30% of 22 cm thus increasing the duration of the implementation time by 24 days

Abstract:
Darrieus turbine use blades with a hydrofoil shape, so the rotational ability is influenced by lift force. This caused the initial rotation capability to be very low when compared to the drag turbine type. The flow velocity distribution in the vertical direction indicates a small cross-sectional speed of flow approaching the base of the flow channel, then rising towards the surface. Darrieus Spinning Top turbine is the result of innovation and design based on the concept of flow velocity distribution. Darrieus Spinning Top turbine’s blade shapes are circular-arc and straight-line, adjusting flow velocity distribution of 0.2H, 0.6H and 0.8H from the top of the turbine. In this study, a performance comparison was conducted between Darrieus turbine and Spinning Top Darrieus. Darrieus turbines produce RPM and torque values of 54.59 – 67.90 and 0.014 – 0.029 Nm, respectively. Darrieus Spinning Top turbines produce RPM values and torque of 69.24 – 82.02 and 0.012 – 0.020 Nm respectively. RPM improvements in Darrieus Spinning Top turbine design increase the influence of lift force (increased λ value). This results in a high lap rate, but requires a high self starting to perform the turbine rotation cycle.

Abstract:
Agriculture land in the transmigration location of Palingkau Asri is one of the development locations for tidal land development in Kalimantan. In its development this location has been divided into three settlement areas (SP), one of them is the SP-2. The focus of this research is Lahan Usaha Satu at SP-2. There are already irrigation networks consisting of irrigation channels (a simple drainage system) in the form of primary pilot channels, primary auxiliary channels, and tertiary channels. The main problems of this location include the excess of water that occurs in rainy seasons and a water system that does not function properly. To overcome these problems research was carried out in the following steps. Firstly, primary and secondary data were taken. Secondly, the water system optimization was examined using a mathematical model that was solved by using the HEC-RAS software package. Lastly, the problem of the excess water (floods) was solved by determining a dike height for a period of 25 years and optimizing the water system with water management structures such as watergates. The results indicated that the existing water management system still can handle the excess of water although the tertiary channels were overflowed (channel of T2, T4, T6, T12) especially at T6, where the overflow reached a maximum value of 1.1 m. The simulation with HEC-RAS

Abstract:
During this time to get the value of California Bearing Ratio (CBR) planners will conduct field tests and/or laboratory tests. This takes time and is relatively large. For this reason, it is needed a practical matter or formulation about the relationship between soil parameters so that planners do not need to test the overall soil parameters. This study aims to obtain a graph or correlation of the Plasticity Index (PI) with California Bearing Ratio (CBR) for clay soils in the Palangka Raya region. Clay soil samples were taken at 3 (three) locations in the City of Palangka Raya. Based on the results of tests on several samples obtained the largest CBR value in soil samples from Tangkiling village which reached a value of 6.56%. While the lowest CBR value obtained from the village of Kereng Bengkirai is 3.14%. For the PI value, the biggest value obtained in Bukit Rawi village is the largest, namely 20.54% and the smallest PI value obtained in Tangkiling village is 9.01%. In general, it can be concluded that the CBR value of clay is inversely proportional to the value of PI. Wherein it is known that the greater the CBR value, the smaller the PI value and vice versa. The overall correlation results of the PI value (plasticity index) to the CBR (California Bearing Ratio) obtain the correlation results using the linear graph CBR = -0.28383 PI + 8,9843. While the correlation value based on analytical calculations obtained CBR = -0,3006X + 9,0190. This test shows that the correlation value has a very high relationship when viewed from the benchmark correlation results (R = 0.80-1.00). The results of the correlation value using linear regression graphs worth R = 0.8489 and using analytical correlation methods worth R = 0.9283. So the final result of this study is to look for a relationship between PI values ??and CBR values. Then for the value of R is taken the smallest value that is R = 0.8489.

Floods that occurred in the city of Banjarbaru especially those that occurred in residential areas caused problems for the community as well as challenges for the government to evaluate the drainage channel in the settlement. The existing rainwater drainage channels need to be reviewed and developed so that they can accommodate the water flowing in the area. One of the settlements that had occurred in the city of Banjarbaru was a residential area in Cempaka Subdistrict, Cempaka Village, precisely on Jalan Getah Tunggal. The data needed in this study are rainfall data, land use data, topographic data and existing data on channel conditions at the study site. Rainfall data were analyzed by Log Pearson III, Gumbel and Iwai Kadoya methods, then tested by Chi Square to choose the distribution of statistics received. The rainfall data was analyzed into the intensity of hourly rain using the mononobe method. Rain intensity is analyzed using a rational method to get a plan debit (Qchannel). Furthermore (the plan) is compared with (Qchannel), and (Qexisting). Based on the calculation results obtained (Qplanning) of 0.76 m3/sec, (Qchannel) of 0.78 m3/sec, (Qexisting) of 0.0645 m3/sec, the comparison results are obtained (Qchannel)>(Qplanning), (Qexisting) <(Qplanning). So that it can be concluded that the causes of flooding and inundation are sediments as high as 70 cm which reduce the storage capacity of the initial dimensions of the channel

Abstract:
The problem of providing clean water is currently a special concern for developed countries and developing countries. Indonesia as a developing country cannot be separated from the problem of providing clean water for its people. One of the main problems faced is the lack of available sources of clean water, the uneven distribution of clean water services, especially in rural areas and existing clean water sources that have not been utilized optimally. This study aims to analyze the clean water needs of PDAM Samboja which uses 2 pumps in the next 10 years (2028). By using primary and secondary data obtained from PDAM Samboja and a number of related references, it was found that the IPA clean water needs of PDAM Tirta Mahakam Samboja with 2 pumps, in 2018 amounted to 2,599.5 m3/day. With the estimated results of the number of customers in the next 10 years (2028), the number of water requirements is 3,048 m3/day. Therefore it is necessary to add 1 pump to the PDAM Samboja IPA so that it can still serve the needs of customers in the next 10 years

Abstract:
The city of Palangka Raya has these peatlands spread across several regions including populated areas. This needs special attention in the world of concrete construction because the peatland has peat water with a high level of organic matter, low acidity (pH) which results in acidic water. The acidity of peat water will cause problems in concrete construction because it will affect the physical and mechanical properties of concrete which will make the concrete corrosive. This research method is by making 27 K-250 concrete samples, each of which three examples will be immersed in peat water, Kahayan river water, and tap water for one month, two months and three months. The results showed that the concrete soaked in peat water had the most significant decline compared to the concrete soaked in Kahayan river water and tap water, which was 8.798% of the planned concrete compressive strength of 250 kg / cm2 while the concrete with river water immersion decreased by 5.882% and tap water immersion 2.966% from the planned concrete compressive strength of 250 kg / cm2.

Abstract:
Clay soils generally have low CBR and UCS values. Has poor characteristics. In Central Kalimantan the prices of CBR and UCS are low. The soil of clay by its predominance is fine grain easily by air. Some efforts to improve the soil are carried out by stabilizing the soil. One of the clay stabilizing ingredients that can be used is salt. The use of salt as a soil stabilizing agent can provide better benefits compared to other ingredients such as chemicals, sand and semen. The aim of the study was to determine the values of CBR and UCS Soil in Central Kalimantan before and after stabilization using salt. The study was conducted at the Land Mechanics Laboratory of the University of Muhammadiyah Palangkaraya. Samples of clay soil will be given in 6 (six) Regencies in Central Kalimantan Province. Tests carried out on clay are CBR tests and tests before and after stabilization with salt. The salt mixture released is 5, 10,15,20,25% and 30% of the dry weight of the clay. Based on the results of the study indicate that the original land CBR value between 3.90% to 4.75%, can be referred to as land that has a poor / low carrying capacity. Then after stabilizing 5% to 15%, the CBR value increased to reach 5% to 9%. However, after being mixed with salt as much as 20% to 30%, the soil CBR value is adjusted significantly. From this it can be explained that the CBR value reaches the maximum value with a salt rate of 10% to 15% of the weight of the soil.

Abstract:
In analyzing the comparison of the cost of acceleration with the acceleration time used by the method Time Cost Trade Off. The analysis is done by using / shortening (crashing) time of implementation by using an alternative to increase working hours (overtime) for 3 hours. With apply the TCTO analysis, the implementation of the construction of the Sei Hanyu Bridge project after its duration performed calculations using the crash duration method, it was found that the time needed to accelerate the construction of the Sei Hanyu Bridge in Kapuas Regency for 1038 calendar days(148 weeks), can be accelerated 44 days from the original planning 1082 calendar days (155 weeks). With the acceleration of the completion of the construction of the Sei Hanyu bridge in Kapuas Regency, an additional fee of Rp. 175,160,710.43 is required with an additional cost (cost slope) of Rp 3,980,925.24 per day for 44 days, so the optimal costs needed to accelerate the construction of the Sei Hanyu bridge in Kapuas Regency was Rp. 45,102,729,928.11 originally planned for Rp.44,927,569,217.68

Abstract:
In 2015 the total area of oil palm plantations in Kalimantan reached 3.47 million Ha with a production of 8.12 million tons per year. Solid waste is in the form of fresh fruit bunches and palm shells. The result of combustion of oil palm shell waste in the form of boiler crust ash is a waste that has chemical elements SiO2, Al2O3, and CaO, with the content of these compounds can affect the strength of the concrete and can increase its strength. In this study, the quality of the concrete mix planned at 28 days is 23 MPa. Concrete testing included compressive strength tests carried out at 3 days, 7 days, 14 days, 28 days, 42 days and 56 days. Before making concrete samples, the mortar compressive strength is tested first by varying the boiler crust ash content by 0%, 15%, 25%, 35%, and 50% to obtain the optimum mixture. Based on the results of the analysis of compressive strength mortar obtained the optimum mixture of 15% for the manufacture of concrete that will be compared with normal concrete. The compressive strength of concrete with the optimum mixture at 28 days is 24.44 Mpa more than the compressive strength of the 23 Mpa plan. Concrete that has the highest compressive strength occurs at the age of 56 days is concrete with the normal mixture with a compressive strength of 34.44 Mpa higher than the compressive strength of concrete with an optimum mixture of 15% boiler crust ash which is 28.51 MPa.

Abstract:
Procurement of goods and services is needed. Mechanism for the implementation of Procurement of Goods / Services, namely through self-management and / or selection of goods / services providers. Self-management is a work that is planned, done and supervised by the institution itself, where in its implementation it can be carried out by PPK, other government agencies or community groups / NGO grant recipients, while for the selection of providers of goods / services can be through: public auctions, simple auctions, direct appointments , contests / contests, direct elections, limited auctions, direct procurement. Principles in the procurement of government goods / services include principles of efficiency, effective principles, principles of transparency, open principles, competing principles, principles of fairness / non-discrimination and principles of accountability. While ethics that must be obeyed include carrying out duties in an orderly manner, full of sense of responsibility, for the smooth and accurate achievement of the objectives of procuring goods / services, working professionally by upholding honesty, independence, and keeping information confidential, not directly influencing or indirect results resulting in unfair competition, a decrease in the quality of the procurement process. Responsible for all decisions determined in accordance with their authority, preventing the occurrence of conflict of interest of parties involved directly or indirectly in the procurement process. Prevent financial leaks and losses. In the implementation of procurement of goods and services, it should not blame authority and carry out joint activities with the aim of personal gain, class, or other parties directly or indirectly, not accepting, offering and or promising to give gifts, rewards, or anything to anyone what is known or deserves to be suspected related to the procurement of goods / services.

Abstract:
Land is the foundation for construction. Foundation is the lowest part of a construction, serves to channel the load directly from the construction structure to the soil layer at underneath it. Soils that have bad properties are very unfavorable if used for something construction, especially for highway pavement. The way to increase the carrying capacity of clay soil is to do soil stabilization efforts, that is, using roadbooster as a stabilizing chemical and is expected to improve the nature of the clay and meets the requirements for road pavement materials. In this study will stabilization of the clay soil of Tumbang Rungan Village Palangka Raya with the main parameters which is used as a research reference, namely California Bearing Ratio (CBR) immersion and Unconfined Compressive Strength (UCS). Based on the results of testing the clay soil of Tumbang Rungan Village, Palangka Raya, the data were obtained: Original ground immersion CBR 7.89%, CBR immersion 0% roadbooster 76%, CBR 4% immersion roadbooster 40.85%, CBR immersion 8% roadbooster 27.08%, UCS original soil 0.56 kg / cm2, UCS 0% roadbooster 7.30 kg / cm2, UCS 4% roadbooster 7.40 kg / cm2, and UCS 8% roadbooster 8.30 kg / cm2. From the CBR data, you can see the value The highest CBR is when mixing 0% roadbooster or without additional roadbooster, while the highest UCS value lies in mixing 8% roadbooster.
