Abstract

This study is to analyze the accuracy of height measurements using the Waterpass as high measurement of height and Kolida Theodolite DT 02. The location of the study was conducted in the Cawang Campus UKI area in November 2018. The method used is the measurement of the different height of polygon with a closed-loop by using Waterpass B2 and Kolida DT 02 Theodolite by using Tachymetri. Measurements are made three times with different loop, with the starting point and the end are the same point. The results showed that the calculation of the high closing error in rings 1, 2 and 3 with the Waterpass were 1 mm, 4 mm and 6 mm respectively. Whereas the high closing error with Theodolite Kolida DT 02 is12mm, 6mm, 19mm respectively. The Standard deviation of height difference with Waterpass is 1mm while with Theodolite 19mm. The conclusion that can be drawn is the Theodolite Kolida DT 02 can be used for high measurements in jobs that are not required to be very high accuracy. Keywords : Tachymetri:high measurement;accuracy

Abstract

The calculation of the area is widely used in the engineering sector, for example housing development, land and property taxes, and other purposes. In this study, the calculationof the area was carried out using a case study of the Kalibaru River Basin, Cawang Village. The selection of this area is intended to contribute to the size of the watershed area as preliminary data that can be used to anticipate flood disasters in the Cawang area.There are many methods for calculating the area, but in this study the method used is the Simpson’s method compared to the Trapezoid’s method. The advantage of the Simpson’s method is that the formula derives from taking into account the curved area of ​​the boundary, compared to the Trapezoid’ method which does not take into account the curved edge of the area.The results show that the watershed area using the Simpson’s method is 0.03% greater than the Trapezoid’s method. Meanwhile, the percentage of standard deviation for the mean of the area calculated by the Trapezoid’s method is 0.0287%., while the percentage of standard deviation for the mean of the area calculated by the Simpson method is 0.0261%, it can be said that the result of Simpson’method close to the true magnitude compared Trapezoid’s method.Keywords: Area;, Accuracy; Offset;Simpson; Trapezoid

Abstract

Remote sensing data has capability to detect Water Surface Temperatures in spatial or temporal analysis. Sea surface water temperature (SST) is one of the important indicators of dynamic global climate and dynamic regional climate. The increasing of SST will be effect to global warming and climate change and resulting in disaster such as hurricane, extreme heavy rain, landslide, tornado, melting ice in polar that resulting sea water rises. Indonesia as an Archipelago that consist of ten thousand islands, sea water rise scan cause a small island to sink. This research is aim to early detect SST with Remote Sensing to anticipate Global Warming. The method is literature study from related science journal as a result from researchers. Result of scientist’s researchers in Indonesia show that there has been increase of water surface temperature that has been varied in period over 32 years.It is need an effort to anticipate that there is no disaster.

Abstract

Saat ini Indonesia dilanda pandemi virus Covid-19 sehingga membuat masyarakat semakin sadar akan pentingnya pola hidup sehat, salah satunya dengan melakukan olahraga seperti bersepeda. Berdasarkan survey di lapangan semakin banyak warga Jakarta bersepeda, baik secara pribadi maupun secara komunitas. Namun peningkatan pengguna sepeda di DKI Jakarta belum didukung oleh fasilitas untuk pengguna sepeda seperti kurangnya jalur sepeda dan tidak adanya parkir khusus yang memadai. Salah satu jalur sepeda yang sering dilalui di DKI Jakarta adalah jalur sepeda di Jalan Pemuda Jakarta Timur, jalur yang sering dilalui pesepeda karena jalur tersebut dekat dengan Jakarta In Velodrome yang merupakan tempat masyarakat Jakarta Timur berolahraga. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang mempengaruhi keinginan pesepeda untuk menggunakan jalur sepeda di Jalan Pemuda Jakarta Timur. Data yang digunakan dalam penelitian ini adalah data hasil kuisioner yang didapatkan dengan cara membagikan kuisioner secara online menggunakan Google Form kepada masyarakat kota Jakarta Timur yang menggunakan sepeda. Metoda yang digunakan dalam penelitian ini adalah metoda analisis Regresi Linear Berganda. Berdasarkan analisis yang telah dilakukan, ternyata terdapat 6 faktor yang menambah keinginan untuk bersepeda di jalur sepeda, Jalan Pemuda, Jakarta Timur yaitu jalur sepeda mudah dijangkau, garis batas sudah masih bisa terlihat, jalur tidak disalahgunakan, tersedia traffic light yang baik, tersedia tempat parkir dan rambu larangan parkir untuk moda lain. Adapun mayoritas responden memilih bersepeda untuk berolahraga, dengan pengalaman bersepeda selama 1-5 tahun. Faktor yang paling menambah keinginan pesepeda melewati jalur sepeda di Jalan Pemuda Jakarta Timur adalah tersedianya traffic light yang baik di jalur sepeda, sebaliknya faktor yang paling sedikit menambah keinginan pesepeda melewati jalur tersebut adalah adanya rambu larangan parkir untuk moda lain pada jalur sepeda

Abstract

ABSTRACTThe quality control system in construction projects is important to ensure that the work carried out meets quality standards in accordance with the established implementation time schedule. The larger the scale of a project has an impact on the complexity of the construction work that must be controlled so that a method is needed to control the quality of the work. In this study, the method used is the Statistical Process Control (SPC) method by taking a case study of the construction of One Tower BSD City which has a height of 22 floors and 3 basements. The research was conducted on the quality control of the tested concrete samples using Statistical Process Control (SPC). The results of the analysis of the quality of the concrete carried out on the foundation floor work with the concrete test sample taken from the inspection document data of the implementing contractor's production process. This research method uses descriptive qualitative in the form of analysis of compressive strength variability and slump test on concrete samples. The results showed that there was no deviation in the strength of the concrete based on the specified quality standard, namely f'c 35 MPa. There was a deviation in the results of the slump test of the concrete sample with 5 test results that were below the lower control limit, without affecting the results of the compressive strength of concrete samples.

Abstract

Sentani Jayapura International Airport is the largest and busiest airport in Papua because apart from serving travel routes to and from Papua. This airport is also a hub to serve travel routes to and from the interior or the Central Mountains in Papua. Therefore, this airport serves various sizes of aircraft from small planes to large planes, which causes a high traffic flow of aircraft movements on the runway. This study will examine the addition of a second runway by analyzing aircraft movements in the next 10 years using regression analysis and analyzing runway capacity and then planning the runway geometry using the FAA (Federal Aviation Administration) and SKEP77 (Government Decree on Airport Operation Technical Requirements). ). The results showed that the prediction of aircraft movements in the 5th year reached 35 aircraft movements every hour. This shows that the capacity on the runway is classified as dense (overload). Therefore, it is necessary to add a second runway so that the aircraft movement is more optimal. Based on the results of the KKOP analysis, there is still room for a second runway with a distance between runways of 350 m. The geometric calculation of the second runway based on the type of aircraft served and its geographical location, obtained a length of 3,000 m with a width of 45 m and a runway shoulder of 7.5 m

Abstract

The high risk of recurring tectonic earthquakes in Indonesia requires regular monitoring. One method that can be used in monitoring earthquakes due to tectonic activity is to observe the position of a monitoring point with GPS. It can provide an overview of the movement of point continuously. GPS is one of the references in geodynamic studies to observe patterns and changes in the direction of movement of blocks of the earth's crust in analyzing active faults in the earth. The position observation method can describe the condition of the monitoring points during one tectonic earthquake phase (earthquake cycle), namely inter-seismic, pre-seismic, co-seismic, and post-seismic. It is necessary to study as early as possible the deformation of tectonic plates so that in the future the risk of damage and loss to the environment due to earthquakes can be minimized. This paper aims to examine GPS technology in monitoring earth dynamics using the literature study method. By inputting GPS data and the output is the fault activity model, it is possible to determine the potential earthquake disaster model in the area studied. It is important to have good and responsive disaster management to minimize the damage caused by a disaster. Areas with a potential for earthquakes must have technology to know if there is an earthquake and where a tsunami will occur, have the infrastructure to transmit this information to residents, and residents must be prepared to know what to do.
