2022-10-28T13:58:11+08:00

In the world of construction, mortar has many functions, for example as an adhesive for precast concrete, filling voids in concrete and grouting materials. In this modern era, there are many additives that can be used to make mortar stronger and make it easier to manufacture. In this study, the additives used were Visco flow 3880 lv, Master gelnium 8305, and Consol flow 168. These additives able to slow down the drying process and can increase the strength of the mortar. This research is an experiment conducted at the Makassar Concrete Bosowa Laboratory. The composition of the mortar that will be used in this test is 1 kg of cement: 2 kg of sand. The dosage for each additive is 0.8%, 1%, and 1.2%. From the results of the study using a visco flow superplasticizer with a dose of 0.8%, 1%, and 1.2%, respectively, the results were 34.69 mpa, 35.10 mpa, 33.42 mpa. By using master glenium got 33.40 mpa, 34.20 mpa, 29.37 mpa. Meanwhile, using the console flow 30.80 mpa, 36.39 mpa, 36.10 mpa

Analisis Risiko Kecelakaan Kerja Pada Pembangunan Konstruksi Tower Besi Baja SUTET

2022-10-28T13:58:33+08:00

The implementation of construction activities has the potential to cause hazards or risks that can cause losses that can be said to be a lot in terms of time, material, and cost. At each work location there is a risk of work accidents that can interfere with work activities in a work activity. Things that cause work accidents are the lack of knowledge of good Occupational Safety and Health (K3) and also the lack of implementation of the Occupational Health and Safety Management System (SMK3). Transmission tower construction work is part of infrastructure work that has a fairly high level of risk in the construction world due to the lack of awareness of the workforce to use PPE and are free from aspects of work machines and equipment. This study intends to understand the OHS risk and measure the level of risk. The type of research is quantitative research with the method used in risk assessment in this study is AS/NZS4360. The data was obtained from a questionnaire technique distributed to respondents, while the intended respondents were contractors who had knowledge of K3. From the results of the study, it was found that the most potential risk of falling objects occurred with a percentage of 32% and the potential risk of falling workers had the highest potential risk (High Risk).

Cold Paving Hot Mix Asbuton is a mixture of asbuton consisting of aggregate, granular asbuton, rejuvenator and other added ingredients mixed with cold heat. Hot and cold mixed asphalt asphalt is a ready-to-use asphalt mixture product that is used as a pavement surface layer for low traffic volume roads. The purpose of this study was to obtain the effect of adding styrofoam to the Marshall characteristics of the CPHMA type Buton asphalt mixture with repeated immersion. This study uses styrofoam waste with the addition of 5%, 10%, and 15%. Samples of test objects made as many as 33 samples, 6 normal samples and 27 samples of variation. Treatment of the specimens was carried out with repeated immersion variations of 6, 12, and 18 days. The manufacture of test objects is hot mixed and refers to the 2018 Bina Marga Specifications, the test is carried out with the Marshall test equipment. The results of this test indicate that the effect of Styrofoam waste as an additive in the CPHMA type Buton asphalt mixture with repeated immersion can cause the value of density, stability, MQ, and VFB to decrease. While the value of flow, VMA, and VIM increased

2022-10-28T13:59:09+08:00

Expansive clay soil is a soil that has poor soil properties in most parts of Indonesia. It has soil properties that easily absorb large amounts of water so that it has sensitivity to the influence of water and is very easy to expand. construction by adding stability material aims to increase the bearing capacity of the soil. using waste carbide and fly ash as a stabilizing agent. This study used 12% addition of waste carbide and variations of fly ash 2.5%, 5%, 7.5%, 10% and 12.5% of the dry weight of the soil. From the results of this study, it was found that the compressive strength and shear strength test values with the addition of 7.5% fly ash + 12% carbide waste experienced a maximum increase, so that the maximum free compressive strength qu value was 1.145 kg/cm2 and the direct shear strength got the maximum shear strength value of 0.6688 kg/cm2.

Analysis of water loss in the lonrong secondary channel in the irrigation area of the Bissua weir, Gowa Regency, was guided by Burhanuddin Badrun and A. Rumpang Yusuf . The existing irrigation system in the Bissua Dam area began to be built in 2001 and completed in 2004 which is located in Towata Village, North Polongbangkeng District, Takalar Regency, South Sulawesi .This study is to analyze the efficiency and water loss in the Lonrong Secondary irrigation network, Takalar Regency. The study was conducted on a secondary channel. Efficiency and water loss were analyzed using the Inflow – Outflow method. The data used in this analysis is primary data in the form of flow velocity data with a current meter for secondary channels. The flow velocity obtained according to measurements in the upstream secondary is on average 0.37 m/s, while for the downstream the average is 0.167 m/s. For the upstream discharge it is 39,555 m3 / second and for the downstream it is 32,461 m3 / second. The overall water loss in the secondary irrigation network is 7,094 m 3 /second on average

Substitusi Agregat Halus Dengan Serbuk Kaca Terhadap Kuat Tekan dan Kuat Lentur Beton dengan Penambahan Zat Epoxy

2022-10-28T14:00:00+08:00

The construction world has developed very quickly in recent years. Concrete is one example. Over time many new innovations have emerged to strengthen the concrete itself and the means of reducing waste that exist in the community. The purpose of this study was to obtain the influence of partial substitution of sand with glass powder by 40%, 50%, 60% and the addition of epoxy substances by 10% on thestrength of concrete bending press. 44 samples were made, including 20 normal concrete samples and 24 variation concrete samples. Concrete will be soaked for 28 days. Testing of compressive strength, and bending strength of concrete is carried out when the life of the test object reaches 28 days. The results of this test show that variation concrete has a compressive strength, and a higher bending strength of concrete than normal concrete. The more use of glass powder on the concrete mixture, the more decreased the compressive strength, and the strength of its lentur. However, the compressive strength and flexural strength of variation concrete are still higher than the normal compressive and flexural strength of concrete. Epoxy does not have a great impact on concrete containing glass powder.

Peningkatan Kapasitas Jalan Kabupaten Dan Evaluasi Kelayakan Ruang Manfaat Jalan

Road capacity is the ability of a road segment to accommodate the ideal traffic flow or volume within a certain time unit, expressed in the number of vehicles that pass a certain road section in one hour (vehicles/hour), or by considering the various types of vehicles passing through a road, the unit is used. The capacity uses units of passenger cars per hour or (pcu) / hour. The road being analyzed is the Jatie – Bua road along the 25 km in Tellulimpoe sub-district, Sinjai district. The purpose of this study was to determine the capacity of the Jatie – Bua road and have the space belonging to the Jatie road segment according to existing road standards, the analysis was carried out using the 1997 road capacity manual method. Based on the analysis and discussion, the road capacity of the Jatie – Bua segment was stored as follows C = 1373.9 pcu/hour. The results of the study, it was also found that several permanent buildings and n semi-permanent above the road shoulder, side channel, and safety threshold which is part of the space belonging to the road. The suggestion that can be taken is that the current road capacity is not able to serve for the next few years, so it is necessary to widen the road according to standards with road shoulder adjustments to further improve user safety and comfort.
