Abstract

Research was carried out to see the potential for flooding through Computational Fluid Dynamic simulations, namely a set of methodologies that allow computers to provide numerical simulations of fluid flow. The entire system is transformed into virtual form, and can be visualized via computer. Components in fluid dynamic computing include selection of mathematical models, discretization, numerical analysis schemes, numerical solutions and representation of processes numerically and graphically. Flood mapping can provide information about which areas need special attention so that it can be used as a reference in making policies related to flood management and can be used to increase wider public awareness regarding floods. The HEC-RAS permanent flow module is able to take into account the influence of various flow obstacles, such as bridges, culverts, bends, or obstacles on riverbanks. The permanent flow module is designed for use in riverbank management environments and the determination of flood risk insurance regarding the determination of riverbanks and floodplains. The permanent flow module can also be used to estimate changes in water level due to channel improvements or embankment construction. HEC-RAS permanent flow special module features include double plan analysis, double profile calculation, double culvert or gate analysis, flow optimization, and stable channel design and analysis. From the simulation results and depth classification, information on the area of inundation and areas prone to flood inundation on the Lepo-Lepo River is 29.34 Ha.

Abstract

The aim of the research is to find out or predict how much a project will cost during implementation and to find out the effectiveness of project control using the Earned Value Method. To overcome existing problems, an Earned Value method is used. There are two parameters or indicators used for analysis, namely BCWS, BCWP. Delay deviations can be identified by looking at the Schedule Variance (SV). This method can also be used to determine the efficiency of resource use in the form of the schedule performance index (SPI). The project implementation time aspect has a negative value up to the 12 th week of (SV) -Rp. 44,776,771.84 or schedule performance index (SPI) = 0.82 < 1. The calculation results are obtained from an effectiveness value of 0.85 for controlling project time using the Method Earned Value. In other words, the results of an effectiveness value that is smaller than 1 (one) can be said to be that the Time Performance for the Implementation of the Concrete Pavement Road Work Project in North Kolaka Regency is less effective. From the results of the time performance study using the Earned Value Method, it can be concluded that the Time Performance for the Implementation of the Concrete Pavement Road Work Project in North Kolaka Regency experienced a delay from the initial plan. It is clear that in weeks 1 to 12 the project performance was delayed from the planned schedule

Abstract

Mortar mixture is an important element in civil/construction work. As a binding agent, mortar mixtures are widely used in various types of work with different strength levels according to their needs. Many sand raw materials are often used but do not meet the material requirements, either grain gradation or other requirements. In this research, a compressive strength test was carried out using fine sand with the addition of stone ash, to test how much strength was achieved with varying percentages of additional stone ash. The manufacture of test specimens for this mortar mixture refers to SNI 03-6882-2002. Testing was carried out at 7 days, 14 days and 28 days. With additional variations of 0%, 20%, 40% and 60% stone ash. The results of this research are mortar mixtures with the addition of 20% stone ash will increase the compressive strength from 4.74 MPa without the addition of stone ash to 7.13 MPa, tending to decrease at an additional 40% the compressive strength is 6.96 MPa and at an additional 60% the strength is obtained. press 5.74Mpa. The simple regression equation for the relationship between the addition of the percentage of stone ash (variable x) and the compressive strength value (variable y) is y = -22.578x2 + 14.97x + 4.8122 with the coefficient of determination R2 = 0.97 (very strong).

Abstract

Tujuan kegiatan Pengabdian Pada Masyarakat (PKM) untuk membantu program pemerintah dalam hal menanggulangi dampak penyebaran dan menekan angka kematian akibat adanya virus Covid-19 yang menjadi pandemic global yang telah ditetapkan oleh badan organisasi Kesehatan dunia yaitu WHO. Virus ini pun masuk ke Indonesia awal Maret 2020, sehingga mengubah perilaku dan tatanan kehidupan baru. Sehingga diperlukan adanya sikap yang harus diubah, salah satunya adalah kegiatan mencuci tangan, memakai masker, menjaga jarak, serta konsumsi makanan yang bergizi. Berdasarkan bukti ilmiah, COVID-19 dapat menular dari manusia ke manusia melalui percikan batuk/bersin (droplet), tidak melalui udara. Orang yang paling berisiko tertular penyakit ini adalah orang yang kontak erat dengan pasien COVID-19 termasuk yang merawat pasien COVID-19. Rekomendasi standar untuk mencegah penyebaran infeksi adalah melalui cuci tangan secara teratur menggunakan sabun dan air bersih, menerapkan etika batuk dan bersin, menghindari kontak secara langsung dengan ternak dan hewan liar serta menghindari kontak dekat dengan siapapun yang menunjukkan gejala penyakit pernapasan seperti batuk dan bersin. Selain itu, menerapkan Pencegahan dan Pengendalian Infeksi saat berada di fasilitas kesehatan terutama unit gawat darurat
