South Kalimantan is one of the areas that has a lot of swamps. The use of galam wood is an alternative to the construction of landslide resistors on the roadside in swamp areas. Landslides often occur on the edge of road piles in swamp areas. Not infrequently damage due to landslides on several roads. This study aims to determine the effect of galam wood plaster reinforcement on increasing soil carrying capacity and stability of embankment due to the operation of external forces. The factor of manual embankment slope safety with the fellenius slice method shows that SF = 0.857 <1.0 "is not safe" so there will be a collapse on the slope of the embankment. Then the embankment stability analysis is carried out gradually, so that an increase from cu = 1.04 t/m2 to cu = 1.8 t/m2. The results of the analysis carried out manually revealed that the total decrease was = 284.62 cm � 285 cm. For the simulation results with the PLAXIS program, it shows that there is a decrease of 3.1 cm.

The aim of the study was to provide an overview of the specifications of primary coating materials and their application method for corrosion control under the fireproofing of pipe rack structures and supporting structures of equipment in the oil refinery industry. The target to be achieved from this research is the availability of specifications of the primary coating material and the ease of its application to the structure of the pipe rack and the supporting structure of the oil refinery industry equipment. This research is an applied research method with a case study approach, namely in order to overcome the problem of corrosion under fireproofing. Allegedly the cause of corrosion under fireproofing is because in the refinery project specifications there is no provision of primary coating applications under fireproofing. The assumptions developed in answering the research problems are the availability of specifications of materials and methods for primary coating applications under fireproofing so that corrosion under fireproofing can be controlled and reduced. Specifications of primary coating material with service temperature (-45)oC - (650)oC with hi-built epoxy coating material, epoxy phenolic, epoxy nonov, inargonic copolymer and multi polymetric matrix, fulfilling NACE SP 0198-2010 technical specifications and application methods primary coating with a variation of the thickness of the primer coating is 100-200 micron (dry film thickness) DFT, proven to be suitable and suitable to be used to control corrosion problems under fireproofing. The results of this study also recommend that the specific material and primary application method for coatings that have been compiled in the primer guidelines for coatings that are in accordance with the specifications of NACE SP 0198-2010 can be used as the standard.

Stabilization is an attempt to improve the physical and mechanical properties of the soil so that it meets specific technical requirements. One method of stabilization is the addition of portland cement additives. This study aimed to compare the CBR values of soft soil of peat before and after stabilization with portland cement and to determine the effect of variations in ripening time on carrying capacity of soft soil peat. Soft peat soil used was taken from Handil Bakti Village, Alalak District, Barito Kuala District, South Kalimantan Province. Variations in the addition of cement levels used 5%, 10%, and 15%, while the variety of curing time starts from 7 days, 14 days and 21 days. In the results of the modified Proctor compaction test, the addition of cement levels in the soft soil of peat was shown to increase the maximum dry weight volume (?d) value continuously. While the value of optimum water content (?opt) has decreased which is not too significant at each addition of cement content. For the value of the soft soil type of peat mixed with cement, the increase in weight compared with the original soil type weight. In CBR Laboratory testing using modified Proctor compaction at 15% cement content addition and 21 days curing time, the maximum CBR value of the Laboratory was 18.039%.

Jalan Temanggung Tilung is a 2/2 UD type road (two undirected two-way lanes) with a road width of 5.5 meters, which is a connecting road between two major roads, namely the RTA road. Milono and the path of G. Obos. Over time, the volume of traffic through these roads increases every year, plus roadside activities that also increase cause congestion at several points of the way. To overcome this problem, the local government carried out road widening to increase the capacity and level of road services. The study was conducted to determine the amount of traffic volume, performance, service level of the Temanggung Tilung road section at peak traffic hours before and after road widening. Data retrieval is done by the direct survey to the field to obtain primary data in the form of geometric road data, two-way traffic volume data, and side obstacle data. Performance analysis refers to the 1997 Indonesian Road Capacity Manual (MKJI) for urban roads. From the results of data processing, before increasing the road (Type 2/2 UD), the traffic volume that passes through the path is 842 pcs/hour and after road widening (Type 4/2 UD) the traffic volume for two directions is 973 pcs/hour, with route A equaling 528 pcs/hour and direction B equaling 445 pcs/hour. Based on the analysis of road performance before road enhancement, the capacity = 2551 pcs/hour, saturation degree = 0.331, and the service level of the two-way road are level B. Based on the analysis of the performance of the way after increasing the way, the direction capacity A = 2686 pcs/hour and direction B = 2674 pcs /hour, saturation degree for direction A = 0.196 and direction B = 0.166, service level for road direction A and direction B increase to level A

In this research, we want to experiment to find out the compressive strength of medium quality concrete K-350 with ingredients added MASTER RHEOBUILD 6, whose function is to accelerate hardening, improve the quality of concrete, reduce water use and increase the value of slump. However, it should be noted that errors in dosages and how to use added ingredients can be detrimental to the quality of concrete. The results of the study show that the addition of 0.25, 0.5 and 0.75 liters per 50 kg of cement can increase the concrete compressive strength. The compressive strength of concrete with the addition of 0.25 liters/50 kg of cement has increased 362.67 kg/cm� from the normal concrete compressive strength of 350.58 kg/cm2. The addition of 0.5 liters/50 kg of cement has increased again to 373.24 kg/cm�, and the addition of 0.75 liters/50 kg of cement has increased the concrete compressive strength to 379.29 kg/cm� of normal concrete. Comparison of compressive strength before and after addition of admixture with an increase of 3.45% in addition of 0.25 liters/50 kg of cement, 6.47% in addition of 0.5 liters/50 kg of cement and 8.19% in addition of 0.75 liters/50 kg of cement.
在本研究中，我们想通过实验找出加入MASTER RHEOBUILD 6的成分后K-350中等质量混凝土的抗压强度。MASTER RHEOBUILD 6的作用是加速混凝土硬化，提高混凝土质量，减少用水量，增加坍落度值。然而，应该注意的是，错误的剂量和如何使用添加的成分可能会损害混凝土的质量。研究结果表明，每50 kg水泥中掺入0.25、0.5和0.75升可提高混凝土抗压强度。加入0.25升/50千克水泥后，混凝土的抗压强度比普通混凝土的抗压强度350.58千克/平方厘米提高了362.67千克/平方厘米。0.5升/50公斤水泥的掺量再次提高到373.24公斤/厘米，0.75升/50公斤水泥的掺量使混凝土抗压强度提高到普通混凝土的379.29公斤/厘米。掺加外加剂前后抗压强度对比，掺加0.25 l /50 kg水泥时抗压强度提高3.45%，掺加0.5 l /50 kg水泥时抗压强度提高6.47%，掺加0.75 l /50 kg水泥时抗压强度提高8.19%。

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.
帕朗卡拉雅市的泥炭地分布在包括人口稠密地区在内的几个地区。这在混凝土施工中需要特别注意，因为泥炭地的泥炭水含有高水平的有机物，低酸度(pH值)导致酸性水。泥炭水的酸性会影响混凝土的物理力学性能，使混凝土具有腐蚀性，在混凝土施工中会出现问题。本研究方法是制作27个K-250混凝土样品，每样3个样品分别浸入泥炭水、卡哈延河水和自来水中1个月、2个月和3个月。结果表明:泥炭水浸泡混凝土与卡哈岩河水和自来水浸泡混凝土相比，混凝土抗压强度下降幅度最大，为250 kg / cm2计划混凝土抗压强度的8.798%，河水浸泡混凝土和自来水浸泡混凝土的抗压强度分别为250 kg / cm2计划混凝土抗压强度的5.882%和2.966%。

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.

Asphalt Concrete-Wearing Course (AC-WC) has been used widely in Indonesia as a surface layer, because of its water-resistant nature and high durability. An essential characteristic of Asphalt Concrete is that its continuous graded aggregate produces a pavement layer with high stability properties. Fillers as fillers in asphalt mixes. In this study, lime was used as a substitute for fillers in the AC-WC mixture. Extinguished lime is a material that passes the no. 200 (0.075 mm), as the primary condition for filler material. The purpose of this study was to determine the Marshall characteristics of the AC-WC mixture using extinguished lime fillers and to assess the performance of the mix and the effect of quenched lime fillers in the AC-WC mixture. The research method was carried out in several stages starting from inspection of 60/70 asphalt penetration, abrasion testing (Los Angeles), screening analysis, aggregate specific gravity testing, Sand Equivalent testing, testing of concrete mixture particular gravity up to testing with Marshall tools. From the results of the study, the use of extinguished filler lime in the AC-WC mixture showed that the use of quenched lime as a filler substitute fulfilled the requirements of stability, flow, VFB, VMA and Marshall Results.
