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

Abstrak Pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman dan kesadaran masyarakat serta sebagai mediator dalam menyelesaikan masalah penurunan hasil panen udang dan ketersediaan air bersih di Bumi Dipasena. Hasil panen udang masyarakat berada dibawah standar dan sangat jauh berbeda dibanding hasil panen perusahaan. Ketersediaan air bersih mengandalkan air hujan yang memiliki batas waktu layak pakai dan menjadi barang langka dimusim kemarau. Kedua permasalahan tersebut menjadi permasalahan utama dan belum terselesaikan selama bertahun-tahun. Banyak alasan yang menjadi penyebab tidak terselesaikannya masalah, mulai dari biaya, tidak adanya kolaborasi antar masyarakat, dan lain sebagainya. Oleh sebab itu, mereka membutuhkan solusi yang tidak hanya tepat guna namun dapat mengakomodasi kepentingan masyarakat. Maka, alternatif solusi permasalahan penurunan hasil panen udang yang disarankan adalah pengontrolan air tambak udang masyarakat dengan menggunakan sistem emulsi membran dan penyediaan air bersih menggunakan sistem ijuk. Kedua solusi tersebut diyakini dapat terealisasi karena terjangkau dari sisi biaya, sistem kontrol tidak kompleks, dan bahan dasar pembuatan sistem dihasilkan oleh masyarakat sendiri. Alasan tersebut menstimulus masyarakat untuk antusias dalam merespon kedua sistem yang ditawarkan dan menginginkan supaya sistem tersebut direalisasikan. Kata Kunci: Sistem Emulsi Membran; Sistem Ijuk Abstract This community service aims to increase people's understanding and awareness as well as a mediator in resolving the problem of decreasing shrimp yields and the availability of clean water on Bumi Dipasena. Community shrimp yields are below the standard and very much different from the company's harvest. The availability of clean water relies on rainwater which has a time limit for proper use and is a rare item in the dry season. Both of these problems have become major problems and have not been resolved for years. Many reasons are the cause of unresolved problems, starting from costs, the absence of collaboration between communities, and etc. Therefore, they need solutions that are not only effective but can accommodate the interests of the community. So, the alternative solution to the problem of decreasing shrimp yields suggested is the control of community shrimp farm water using a membrane emulsion system and the provision of clean water using a palm fiber system. The two solutions are believed to be realized because they are affordable in terms of costs, the control system is not complex, and the basic material for making the system is produced by the community itself. The reason stimulates the community to be enthusiastic in responding to the two systems offered and wants the system to be realized. Keywords: Membrane Emulsion System, Palm Fiber System

Abstract

Abstrak Kejadian Gempa Palu pada tanggal 28 September 2018 telah menimbulkan korban jiwa dan kerugian besar dengan kerusakan pada infrastruktur dan bangunan di tiga daerah Palu, Sigi dan Donggala. Tragedi ini diakibatkan oleh magnitudo gempa yang sangat kuat M 7.4 diikuti oleh tsunami dan peristiwa likuifaksi yang sangat dahsyat. Karena itulah perlu dilakukan survey berikut assesmen data kerusakan bangunan yang terjadi di Palu sekaligus penyuluhan terkait teknis bangunan rumah tinggal tahan gempa. Sesuai hasil survei, likuifaksi terjadi di tiga lokasi yaitu Petobo, Balaroa dan Sigi. Sedangkan tsunami terjadi di pesisir pantai Donggala akibat terjadinya keruntuhan massa tanah yang besar saat terjadi likuifaksi. Beberapa bangunan dan infrastruktur yang mengalami kerusakan disebabkan oleh sifat teknis bangunan yang tidak mampu menahan beban gempa. Secara umum para warga warga Palu dan Sekitarnya di Sulawesi Tengah belum sepenuhnya memahami konsep bangunan tahan gempa khususnya untuk rumah tinggal sederhana. Kata Kunci: likuifaksi, tsunami, kerusakan bangunan, survei, asessemen Abstract The Palu earthquake on 28 September 2018 caused heavy casualties and losses with damage to infrastructure and buildings in three areas which are Palu, Sigi and Donggala.

Abstract

Pertemuan antara balok-kolom pada beton bertulang merupakan bagian dari struktur yang sangat kritis bila terjadi gempa bumi. Hal ini dapat terjadi karena balok-kolom menerima gaya geser yang besar dan sering tidak diberi pendetailan yang baik. Studi analisa ini akan membahas nilai dari kekuatan geser horizontal dari sebelas spesimen pada pertemuan balok-kolom interior dengan mempergunakan metode Softened Strut-and-Tie dan ACI, lalu membandingkannya dengan hasil uji laboratorium yang tersedia di literatur untuk mengetahui keakuratan dari metode yang dipergunakan dalam menentukan nilai dari kekuatan geser. Dari analisa dan verifikasi terhadap sebelas spesimen, metode Softened Strut-and-Tie memberikan hasil yang lebih baik dan mendekati hasil uji laboratorium dibandingkan dengan metode ACI.

Abstract

The continued use of traditional concrete has resulted in a thicker layer of waterproofing, preventing rainwater from entering the ground and increasing surface run off. As a result, the water table drops during the rainy season, and flooding occurs. One of the innovations to anticipate or overcome these problems is using renewable materials such as aerated concrete. Permeable concrete pavements are intended to reduce puddles on the street. By omitting fine aggregate, porous concrete is simple, lightweight concrete. The interconnected cavities result in a high level of porosity. Porous concrete usually has little to no fine aggregate and enough cement paste to coat the coarse aggregate's surface. Due to the increased porosity, the compressive strength of un-sanded concrete is lower than that of conventional normal concrete. Sand-free concrete has much lower tensile and flexural strength than conventional concrete. In this study, two coarse aggregates with nominal maximum sizes of 12.5 mm and 6.7 mm were used as split rocks with weights of 1.123 kg/m3 and 2.63 kg/m3, respectively. Hence, a FAS of 0.35 and a water volume of 0.35 kg using Portland cement type 1 with a quantity of 389.6 kg/m3. The test object is a concrete cylinder with a diameter of 80 mm and a height of 16 mm. After immersing the specimen in a tub of water, each mixture has three specimens.

Abstract

Beams are part of the building structure that is important to consider when designing the structure. Some failures that occur in beams due to beam reinforcement are not installed such as planning/ design procedures, this problem can cause structural failure. Knowing the behavior of the beam structure due to the given load can help predict the strength of the structural beam and the comfort of the planned structure. To determine and predict the strength and comfort of the reinforced concrete beam structure due to the received load, experimental and simulation tests are carried out. VecTor2 simulation is used to predict shear, crack, and displacement forces in reinforced concrete beams when displacement loads are applied. The bond stress-slip effect (0.139) has a good effect on the strength and hysterical response of reinforced concrete beams. From the results of pushover testing and simulations, it is obtained that the ratio for load capacity ranges from 1.00-1.095. In addition, the installation of 135˚ hooks on stirrups shows that the crack behavior that occurs forms an angle of 45˚, this indicates that the bond between concrete and reinforcement is going well, this can be seen from the analogous behavior principle of reinforced concrete beams.

Abstract

The strong column-weak beam is a design concept that needs to be implemented and considered in the planning of building structures (high-rise and low-rise buildings). Generally, structural failure occurs at beam-column joints. Such failure occurred due to the lack of attention to good and correct design concepts. The detailing of reinforcement for columns, beams, and beam-column connections has not yet fully implemented the SNI-2847-2019 standard which results in the reinforcement cannot withstand the combination of tensile, compressive, and shear forces that occur during an earthquake. In addition, the incomplete design of strong column-weak beam in building planning causes the building to fail in the column structure when receiving axial forces. The purpose of this study was to analyze the structural damage and the disaster management system applied during the earthquake in Palu. The research is carried out by investigation/survey methods on the study area as well as checking and recording the data about damage condition of buildings and conducting a hammer test (non-destructive test) to get the strength value of the concrete. Testing result showed the compressive strength value of the f’c concrete used is 20 to 48 MPa. In addition, the details of stirrups reinforcement are also not fully understood about their function on beams and columns, which results in the installation of stirrup reinforcement does not meet the criteria for bending angles of 90˚, 135˚, 180˚ and the addition of tensile and compressive reinforcement lengths. The high potential for earthquake hazard causes Palu and its surroundings tend to have an earthquake risk. For this reason, it is necessary to implement disaster mitigation for Palu region, which aims to reduce the number of casualties when natural disasters occur, both human and property loses.

Abstract

ABSTRACT The September 28th,2018 Central Sulawesi earthquake collapsed various buildings in Palu. One of the buildings that collapsed due to the earthquake was the structure of the Universitas Terbuka building Palu. Based on a survey to the building site, it can be seen that the collapse occurred in the dominance of melting in the column sections so that the structure was unable to stand upright. Therefore, to find out the main cause of the collapse of the Universitas Terbuka Palu building, it is necessary to analyze the seismic response of the structure. The method used is Spectra Response. Analysis of the calculation of deformation, storey drift and base shear is carried out to determine the stability and the main cause of the collapse of the building. The results showed that the Seismic Response of the Universitas Terbuka Palu building structure was not suitable for earthquake loads with the earthquake zoning of the Palu area determined based on SNI 03-1726-2012. The analysis shows that the deformation that occurs is greater than the allowable deformation and the field conditions indicate that the column is experiencing melting so that it collapses earlier than the beam. Keywords: seismic response spectra, Central Sulawesi earthquake, stability, deformation
