Abstract

Road maintenance management in the rural area by the government of North Barito Regency has not gone well. Many rural roads are not maintained because of a limited budget and the government agencies and the private sector on the maintenance of rural roads are not well coordinated, therefore the need for structured management strategies is in demand. This study aims to create a plan of management strategies, and determine the priority of rural road maintenance in North Barito Regency. The analysis of the research was carried out by the analysis of rural road infrastructure using the analysis of assessment criteria and SWOT analysis, analysis of management sequence of the rural road using the Most Desirable analysis by society (MDm), and analysis of the rural roads maintenance costs. The results of the inventory data shows that there are 154 rural roads recorded in the village. Based on the analysis of the assessment criteria, there are 130 roads and the SWOT analysis shows 115 roads, therefore, the rural roads that are categorized in the analysis of rural road infrastructure to be maintained are 115 rural roads. The sequence analysis management using MDm analysis is used to determine the priority order of 115 village road maintenance road. The cost analysis determination is based on government funding sources Barito Utara as much as Rp 1.110.000.000, while the budget plan that is allocated for the maintenance for the 115 village roads is Rp 3.532.482.275, it is therefore necessary to create a strategy. The preparation of the strategy is divided into a long-term strategic plan for five years, and short-term strategic plans for one year. In the first year, there are 36 packages with the allocation of Rp 1.110.000.000, for the second year there are 35 packages with funds allocated as much as Rp 1.137.200.000, for the third year there are 39 packages with funds allocated Rp 1.165.650.000, while there is one work package of 5 packages with funds allocated Rp.168.199.850. All packages of rural road maintenance work can be done with the assumption that each year has been allocated to the budget plan and the planned work program can be completed in 4 years. It is suggested to make some sort of mapping of the location of the inventory, assessment criteria approach in more detailed and accurate to get the actual results.

Abstract

The competitive atmosphere in winning a construction tender is one of the main considerations of the construction service providers to improve their construction efficiency. This issue indicates that the construction services companies that could improve their efficiency to the fullest are those that could reduce work cost and in turn win the tender. Cost competition due to the efficiency may result in unusually low bid price, thus the construction companies try to look for the opportunities to win the tender by planning claim fillings to ensure the profit for the construction service companies. Nevertheless, contract termination claims toward low bidding tender still occur. This fact indicates that the low bidding tenders were not equipped with construction claim planning. Construction claims to the work contractors occurred in Banjar regency are mainly due to the completion lateness, low work volume, low work quality or defect. Those factors result in either contract termination claim or contract reduced value claim. Research method implemented is to interpret data measurement result to obtain data that can be analyzed descriptively from the data processed to result in alternative consideration in the discussion of construction claim in Banjar regency. The result shows that the kinds of construction claim in Banjar regency year 2012 are time claim, cost claims, work scope claims, combined claims, and contract terminations. The causes of construction claims are work volume addition, less work volume, changes in work design, field condition, completion lateness, and the inability of service companies to finish the construction. The resolutions of the construction claims are by negotiating the completion time, work value addition material specification change approval, and contract termination for the service providers who fail to finish the project in time mentioned in the contract. Contracts with very low tender or fewer than 80^ of the budget ceiling are equipped with construction claim design to avoid contract termination.

Abstract

As high-rise buildings continue to grow in number, the availability of land for such development shrinks. This has led to those buildings being constructed in very close proximity of each other. This can be a problem in areas with soft soil, such as Banjarmasin. It is apparent from the fact that those buildings lean toward each other quite shortly after they have been constructed, in such a way that they become structurally unstable. This research aims at finding a solution for this problem. In this research the Soft Soil Creep (SSC) was used to model soil. The parameters include modified compression index (λ*) = 0.13, modified swelling index (κ*) = 0.03, and the secondary compression index (μ*) = 0.029 obtained from soil sampled in Banjarmasin at the Trisakti Port. The value of Cc is 0.9817 , Cs is 0.132 and Cα is 0.176 with vulnerable void ratio (e0) of 1,9-2,3. The simulation suggest that the problem can be solved using a combination of vertical drain and applying a particular amount of load in form of a soil heap on the side opposite that the building is tilted to. It is found the slope can be reduced significantly after only 4 years (U=2.5%). The use of PVD up to 21 meters deep without a soil heap is unable the restore the building to its initial verticality. Hence, it takes a combination of the load and the vertical drain to obtain maximum results. The combined results produce a faster time in restoring the buildings verticality from ± 4.5 years to only ± 3 months.

Abstract

This thesis discuss about the development of synthetic unit hydrograph based on Katingan watershed. There are two synthetic unit hydrograph developed in this research, they are synthetic unit hydrograph of Nakayasu and Gama I, both produce different hydrograph toward observation hydrograph in Katingan watershed. Nakayasu and Gama I are developed to produce synthetic unit hydrograph that comes in accordance with observation unit hydrograph. The two hydrographs are developed by changing constants of peak discharge (TR) and recession coefficient (K) and making squares calculations at the time when the line peaked for Gama I, and changing constants in calculations when the graphics decline for Nakayasu The development of the synthetic unit hydrograph of Nakayasu and Gama I results in hydrograph which is closer to the observation hydrograph. The result can be seen from the smaller error percentage value in Nakayasu as much as 7.97 percent from the initial value of 89.85 percent and 68.11 percent in Gama I from the initial value of 392.63 percent.

Abstract

Sejumlah bangunan seperti aula dan jembatan memerlukan ruangan yang luas tanpa tersekat oleh kolom yang rapat. Hal ini dapat dilayani salah satunya dengan penggunaan balok girder hybrid yang bisa divariasikan tidak hanya dalam hal mutu, tetapi juga ketebalan masing-masing komponen penyusunnya. Girder hybrid rawan terhadap tekuk, tetapi hal ini bisa diatasi dengan pengaku. Pemasangan yang tepat akan menghindarkan kegagalan struktur akibat tekuk, sekaligus diprediksi meningkatkan kemampuan menahan beban secara signifikan. Perbandingan ketebalan antar elemen, kombinasi mutu, dan pengaturan spasi antar pengaku adalah isu-isu penting dalam bahasan pemasangan pengaku. Untuk mempelajari lebih dalam tentang topik-topik tersebut, dikembangkan model balok girder hybrid dengan panjang 7000 mm dan tinggi 900 mm. Variasi model dianalisis dengan Finite Element Analysis (FEA) menggunakan ANSYS Ed.9.0. dengan pilihan plastic shell elemen SHELL143. Elemen baja menggunakan mutu yang dipakai dalam pengujian eksperimental, yaitu baja S570 dan baja SM400. Mutu baja balok kemudian divariasikan dengan menggunakan jenis S690 dan S355. Pembebanan dilakukan hingga kondisi softening dimana beban puncak telah dilewati. Perilaku balok akibat pembebanan diteliti untuk menghasilkan rencana kombinasi mutu dan geometri yang efisien. Sejumlah rekomendasi didapatkan berdasar pola-pola yang ditunjukkan hasil pengujian model. Dalam kombinasi mutu, balok girder hybrid dengan sayap dan badan dibuat dari bahan yang memiliki mutu yang relative besar perbedaannya. Berbagai variasi telah menunjukkan mutu S570 berpasangan dengan SM400 sebagai yang paling baik. Hal ini sesuai dengan yang dipakai dalam pengujian eksperimental. Adapun ketebalan sayap (15 mm) yang tetap tidak bervariasi ternyata cukup diimbangi dengan badan balok dengan tebal setengahnya, ketebalan badan balok dibuat sama dengan ketebalan pengaku. Plat pengaku ternyata hanya sangat diperlukan pada lokasi pembebanan dan perletakan. Jarak antar pengaku yang efektif sebesar tiga kali tinggi balok. Hasil yang didapatkan pada kondisi softening memperlihatkan perilaku yang relative stabi ldengan tidak adanya rapture secara mendadak.

Abstract

Katingan is one of the regencies in Central Kalimantan province, which has deposits of mountain stone and quarried sand in Bukit Tangkiling. Problem in the area is that it is hard to obtain aggregate fraction proportions that pass No. 30 (0.60 mm) sieve as required in the specification of gap graded range, so if the gap graded could not be met, then semi-gap graded is used.HRS is also called gap-graded pavement, which has more fine aggregate than coarse aggregate compared to asphalt concrete, and resulted in flexible pavement that can be passed by vehicles comfortably. HRS-WC mixture relies on the bond between the bonding agents, coarse aggregate, fine aggregate, and filler, unlike asphalt concrete, which relies on coarse aggregate interlocking. HRS-WC utilizes gap gradation and provides good flexibility since the usage of gap gradation gives a high VMA value because more cavities are filled with asphalt. A higher VMA value results in thicker concrete blanket and creates flexible pavement that is comfortably passed by vehicles.Testing standards utilized in this research are Standar Nasional Indonesia (SNI) and American Association of State Highway and Transportation Official (AASHTO). Methods implemented in this research are to identify the characteristics of asphalt mixture that meets the specification.Based on the result of Marshall standard testing in COA 7.3% with gap level of 5%, density value is 2.248 g/cm3, VMA value is 20.40%, VIM is 4.3%, VBM value is 79.45%, stability value is 1375 kg, flow falue is 3.45%, and MQ value is 450 kg/cm. The research shows that the gap level of 5%, 10%, 15% and 20% has high density, VMA, VFB, and flow value, but low stability, VIM, and MQ value. This result shows that there is a strong correlation between Marshall’s characteristic with the gap gradation level. The best gradation variation is variation 1, which is the gradation that has gap level of 5%. Since this variation gives higher value of density, VMA, VFB, and flow, it results in flexible and comfortable pavement.

Abstract

The aim of this research is to analyze the effect of the residents’ trip toward the performance of the region's main road in Wira Praja Housing complex in Muara Teweh. The aspects being analyzed in this research are the model of residents trip as the independent variable (x), the number of family members who go to work form home (x1), the number of family members who are students (x2), the number of family members who do not work or are not students (x3), household size based on the site of the family (x4), the number of car ownerships in units of vehicles (x5), the number of motorcycle ownerships in units of vehicles (x6), the number of bicycle ownerships (x7), total vehicle ownerships in the house (x8), total income per family per month in ten thousand rupiahs (x9), the types of house (between 36 and 45, 45 and 60, and bigger than 60) (x10), and the dependent variable (y) which is the total trips per family per day, and how the residents’ trip influences the performance of the road on the existing conditions. From the data, a forecasting is made for the next 5years.The research result shows the relationship between the number of trips (total trips) in the area of Wira Praja Housing of Muara Teweh as the dependent variable (y) and as the independent variable (x). The best regression model for the prediction of the trip is y = 1,014 + 0,441x8+ 0,004x9.The contribution of vehicles to the traffic on the main road of Wira Praja Housing Complex in Muara Teweh is grouped based on types of vehicles during traffic’s peak hour traffic. The composition of vehicles at peak hours showed that MC contributes 93% and LV contributes 7% to the traffic during peak hours.Each point of observation of residents’ trip shows an existing degree of saturation. On Jl. Wira Praja towards Jl. Pendreh observation point DS1= 0.142, on Jl. Wira Praja towards Jl. Pendreh and Jl. Ronggolawe observation point DS2 = 0.135, and on Jl. Wira Praja towards Jl. Ronggolawe observation point DS3 = 0.143. Based on the regulation (Permenhub No. 14 Year 2006), it is obtained the degree of saturation are sufficient (≤ 0.35), the level of service isA.The assessment of traffic forecasting for the next 5 years is assumed from the assessment of the Wira Praja Housing Complex Muara Teweh, traffic flow outside the housing and the traffic flow taken from the planned educational zones in residential areas. Forecasting is done with a few assumptions of housing development, namely 37, 100, 200, 300, 400, and 500 housing units. To forecast the traffic assessment from all assumption, it is found that the greater the assumptions of the housing development is, the higher the DS value of each point of observation will be.

Abstract

Building maintenance management in the Bandarmasih Passenger Terminal of PT. Pelabuhan Indonesia III (Persero) Branch of Banjarmasin has not been using priority scale method or middle-term maintenance for handling damages, This is due to the fact that the database of building condition is not available. This study aims to create middle-term maintenance strategy plan and prioritise the handling of the building maintenance.Inventory results showed that there were 95 types of work. Based on the analysis of the assessment criteria there were 78 types of work that met the assessment criteria, using SWOT analysis, this number was reduced to 74. Meanwhile, to determine the order of priority of building maintenance the use of MCDM analysis was required.The strategic plans were divided into medium-term strategic plan for 5 years and short-term strategic plan for every year. In 2015 there were 14 types of works determined with an allocation of IDR 502,036,400. In 2016 there were 15 types of works determined with an allocation of IDR 557,611,829. In 2017 there were 11 types of works determined with an allocation of IDR 619,339,459. In 2018 there were 16 types of works determined with an allocation of IDR 687,900,337. In 2019 there were 18 types of works determined with an allocation of IDR 764,050,904. All maintenance works were expected to be completed in 5 years.The strategic plan that has been arranged can be used as preliminary guidelines for building maintenance projects that experience changes in its arrangement of specified list.

Abstract

The working of river normalization is a construction project which has tendency to have the work accidents because of the high frequencies of very modern working equipments. The accidents of work can be influenced by three main factors such they are human factor, equipments factor and environment factor. Some of the recently research showed that the most domain factor which caused the work accidents was human factor since the workers have less knowledge and awareness in how the importance the safety working is.Our government has released a rule about safety working especially for construction sector, which is made in the rules of Transmigration and Labor Ministry No. Per-01/Men/1980. One of the system in the management of safety and healthy working which has been developed and had been made into fix guidance is called OHSAS (Occupational Health and Safety assessment Series) 18000. The purposes of OHSAS is not far away different from the purposes of SMK3 Permenaker they are to protect and reduce the amount of working accident potencies. But in the other side the application of the system is still in a quite distance of satisfaction and so far from optimal action so that we can have many info about the rate of working accidents happening in a seemly high frequencies. Generally, the real condition of the implementation of safety work has been known and done but the persons and institutions who involved in this implementation can not do it totally or as well as possible because of some reasons.Therefore, it should be make safety work implementation strategy in the river normalization to do Permen PU No. 09/2008 of July 1 2008. The government and the supplier signature the policy of K3, signature the aggrement K3 with the partner of work, create PreRK3K and RK3K, to do technical guidance K3, to do the training to make some expert professional of K3 and also to prepare the operational monitoring guidance and evaluate K3 and prepare the guidance of K3 application.

Abstract

The wet Trahean swampland is known as a farming and fishing area for the residents of Trahean village. Trahean swamp covers 1,500 ha, comprising 70.16 ha of farming area, 8 ha of fishing area and other public facility areas of 1411.84 ha. Trahean swampland is water sustainable all year long. Despite long dry season, the Trahean village rarely experiences severe drought. The water source of Trahean village is from rainfall and river branch from Barito River that flows to the farming area. This research aims to identify the characteristic of the swampland so that it can be used as a farming area. The soil type in this area is Aluvial swamp.This research was conducted by collecting primary and secondary data. The assessment of land suitability shows that Trahean swamp has a limiting factor. This limiting factor affects its productivity and thus, this area needs more input. The limits are usually caused by the farmers themselves.Based on the land suitability class result, the Trahean swampland is categorized into S1 and S2 land suitability, where the dominant land suitability is S2. Based on the physical and chemical conditions, the Trahean swampland is suitable for farming.
