Abstract

This research was conducted to analyze and determine the height difference accuracy using the method of measuring the different heights of a closed loop using Waterpass B2 and Total Station Kolida 420SR. The location of research in the Ciloto area, Puncak, West Java with coordinates 107˚ east longitude and 06˚ south latitude, on 14-15 December 2014 using a local high point reference. Measurements were made three times with different looped but the starting and ending points were the same points. Accuracy of calculation is done by calculating the average of the least squares to determine the standard deviation of the measurement results with each equipment. The result is  the standard deviation of the height difference with the waterpass is 0.01mm, while with the Total Station it is 0.02 mm. Based on the results of the standard deviation of the height difference, the Total Station can be used for height measurements in civil engineering project that does not require very high accuracy and height difference measurements with the Total Station are more economical because the time required for measurement is a quarter of the time required height difference measurement with Waterpass. Keywords: height measurement; Waterpass; Total station. AbstrakPenelitian ini dilakukan untuk menganalisis dan mengetahui ketelitian beda tinggi menggunakan metode pengukuran beda tinggi suatu ring tertutup menggunakan Waterpass B2 dan Total Station Kolida 420SR. Lokasi penelitian terletak di daerah Ciloto, Puncak Jawa Barat dengan koordinat 107o bujur timur dan 06o lintang selatan, pada tanggal 14 dan 15 Desember 2014 dengan menggunakan referensi titik tinggi lokal. Pengukuran dilakukan tiga kali dengan ring yang berbeda namun titik pangkal dan ujung adalah titik yang sama. Hitungan ketelitian dilakukan dengan hitung perataan kuadrat terkecil untuk mengetahui standar deviasi hasil pengukuran dengan masing-masing alat. Hasilnya adalah standar deviasi beda tinggi dengan waterpass sebesar 0.01mm, sedangkan dengan Total Station sebesar 0.02 mm. Berdasarkan hasil perhitungan nilai standar deviasi pengukuran beda tinggi, maka Total Station  dapat digunakan untuk pengukuran beda  tinggi pada pekerjaan teknik sipil yang tidak memerlukan ketelitian yang sangat tinggi, dan pengukuran beda tinggi dengan Total Station lebih ekonomis karena waktu yang diperlukan untuk pengukuran adalah seperempat dari waktu yang diperlukan pengukuran beda tinggi dengan Waterpass.

Abstract

Banyaknya volume sampah yang dihasilkan masyarakat baik berupa sampah organik sisa makanan dan daun kering, sampah anorganik seperti kertas, karton, plastik ataupun sampah lainnya saat ini semakin terasa dampaknya terhadap lingkungan. Berdasarkan sumbernya, sampah rumah tangga menempati urutan teratas berkontribusi menambah volume timbulan sampah sebesar 38,3% diikuti pasar tradisional sebesar 17,2%, kawasan 15,4%, perniagaan dan fasilitas publik 12,3% dan lainnya 16,7% dari jumlah total sampah secara nasional. Besarnya timbulan sampah meningkat 4% dari tahun 2019 sebesar 32,02 juta ton menjadi 33,17 juta ton pada tahun 2020 dimana timbulan sampah dominan berada di Pulau Jawa yaitu sekitar 60%-66% disusul dengan pulau Sumatera sekitar 18%-22%, kemudian pulau Kalimantan & Sulawesi sebesar 6%-7%, diikuti Bali, NTT, NTB, Ambon, dan Papua hanya berkisar antara 1%-3%. Perlu paradigm baru dalam pengelolaan sampah berdasarkan perspektif nilai ekonomis yang masih bisa didapatkan dari sampah sesuai prinsip 3R (Reduce, Reuse, Recycle). Peran serta masyarakat secara aktif terhadap implementasi pemilahan sampah rumah tangga akan sangat ditentukan oleh tingkat pemahaman masyarakat. Penelitian ini dilakukan dengan tujuan untuk menganalisis korelasi perubahan perilaku pemilahan dan dan pengolahan sampah di dusun Pade Mare Lombok Utara. Metode yang digunakan adalah analisis deskriptif dengan hasil nilai rata-rata 76.76 untuk pengurangan sampah, 76.67 untuk daur ulang sampah dan 79.03 untuk pengolahan sampah.ABSTRACTThe amount of waste generated by the community, both in the form of organic waste, food scraps, and dry leaves, inorganic waste such as paper/cardboard/plastic or other waste, is now increasingly having an impact on the environment. Based on the source, household waste occupies the top position, contributing to increasing the volume of waste generation by 38.3%, followed by traditional markets by 17.2%, areas by 15.4%, commerce, and public facilities by 12.3%, and others by 16.7% of the total. total waste nationally. The amount of waste generation continues to increase from year to year, wherein 2020 it reached 33.17 million tons per year, an increase of 4% compared to 2019 which was 32.02 million tons per year. Of this amount, the dominant waste generation is on the island of Java, which is around 60%-66%, followed by the island of Sumatra around 18%-22%, then the islands of Kalimantan & Sulawesi at 6%-7% followed by Bali, NTT, NTB, Ambon, and Papua only ranged from 1%-3%. There is a need for a new paradigm in waste management based on the perspective of economic value that can still be obtained from waste according to the 3R principle (Reduce, Reuse, Recycle). The active participation of the community will be strongly determined by the community knowledge level of the implementation of household waste sorting. The study was conducted in Pade Mare, Sambik Elen Village, North Lombok with an average value of 76.76 for waste reduction, 76.67 for waste recycling, and 79.03 for waste processing.

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

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.
