Abstract

ABSTRACTCertain buildings limit displacement of pile foundation with relatively small value so as not to cause damage to the structure. Loading test directly in the field requires a very high cost. To overcome this problem, it can be approached with a more economical cost, that is to move it into a certain scale models. The method used is to create a media model as a test box testing, by simulating the actual model in the form of a scale model. This method is fairly cheap and efficient as it can be used for various models and can be used repeatedly. The study was conducted using models of reduced scale single pile foundation made of concrete with a length of 0.2 m, 0.3 m, 0.4 m and each diameter of 0.02 m, 0.03 m, 0.04 m. Pile model is jacked in clay soil that has been compacted in a box and then given a tensile load test referring to ASTM D3689-07 procedure E (Constant Rate of Uplift Test). Mobilization of uplift resistance is determined from the pile frictional resistance force and displacement of the pile. The results showed that the frictional resistance value is reduced to the value at a particular displacement or at critical displacement pile.Key words : uplift resistance , sand, mini pile.ABSTRAKBeberapa konstruksi bangunan memberikan batasan kepada perpindahan tiang yang terjadi dengan nilai yang relatif kecil supaya tidak menyebabkan kerusakan struktur. Metode uji yang dipakai adalah membuat box uji model sebagai media pengujian, dengan mensimulasikan model yang sebenarnya ke dalam bentuk model skala. Penelitian dilakukan menggunakan model fondasi tiang tunggal skala tereduksi yang terbuat dari beton dengan panjang 0,2 m, 0,3 m, 0,4 m dan masing-masing diameter 0,02 m, 0,03 m, 0,04 m. Model tiang dipasang dengan cara ditekan pada tanah pasir yang sudah dipadatkan dalam box uji kemudian diberikan beban tarik yang mengacu pada ASTM D3689-07 prosedur E (Constant Rate of Uplift Test). Tahanan tarik tiang ditentukan tahanan gesek satuan dan perpindahan tiang berdasarkan variasi pengaruh diameter dan panjang tiang. Hasil penelitian menunjukkan bahwa nilai tahanan gesek satuan ultimit (fs) dan perpindahan kritis (δc) relatif menurun dengan bertambahnya ukuran diameter (d) tiang tetapi sebaliknya nilai fs tiang meningkat dengan dengan bertambahnya ukuran panjang (L) tiang. Semakin besar panjang tiang memperlihatkan kecenderungan bahwa pengaruh tekanan tanah lateral pasir terhadap selimut tiang meningkat sehingga memberikan kontribusi tahanan gesek yang lebih besar, sedangkan penambahan diameter tiang tidak meningkatkan tekanan tanah lateral pasir terhadap tiang.Katakunci : Tahanan tarik, pasir, Model Fondasi tiang.

Abstract

ABSTRACTFires can occur anytime and anywhere and fires are generally known after the fire has begun to grow. Therefore, it is necessary to detect fires that can quickly detect the presence of a fire and prevent fires from getting bigger. This research has made a fire detection equipment where the detection results can be received remotely by utilizing the internet network through FTTH. The transmitter equipment consists of a fire detector using the MQ-2 gas sensor, LM35DZ temperature sensor, processing data using Arduino that is connected to an Ethernet shield and FTTH. The receiver consists of an Ethernet shield, Arduino, and an alarm and LED circuit. Changes in smoke temperature and thickness were detected by Arduino. When the LM35DZ temperature sensor detects temperature changes greater than or equal to 350C and the gas sensor MQ-2 detects smoke thickness greater than or equal to 150ppm, the Arduino microcontroller will provide logic 1 and will activate the buzzer and led. Conversely, if the temperature and smoke thickness are less than the conditions above, Arduino sends logic 0. Arduino uno is connected to the Ethernet shield so that data from Arduino can be sent via the internet using FTTH network. In the receiver, if the data received by logic 1 will activate the buzzer and led which indicates the temperature above 35 degrees and smoke thickness above 150 ppm. Transmitter devices and receivers can be interconnected through FTTH networks with IP addresses that are one network, where the IP transmitter device is 172.31.16.27 and the IP device is 172.31.16.29. The QOS test results for FTTH network are good with packet loss 0 and very small delay which is <150 ms and throughput above 1Mbps.Key : Arduino, buzzer, LED, Ethershield, Fiber To The Home,IoT

ABSTRACTIndonesia which geographically has an area located at 6º LU up to 11º LS and 97º BT up to 141º BT is an area prone to earthquakes. Determination of the temple as a world cultural heritage has implications for the responsibilities and obligations of the Indonesian people in an effort to protect and maintain the building in accordance with the conventions set by UNESCO. The convention, among others, is maintaining the preservation of buildings from the dangers of war, physical damage due to age, and natural disasters. This research was conducted with the aim to determine the effect of groundwater depth and earthquake acceleration on the strength of Prambanan Temple subgrade based on finite element method. Simplification of Siwa Temple as a modeling in software input. The results of the study are the shallower depth of the ground water level, the effective stress of the soil will also be reduced. When effective stress decreases, the strength of the soil will also decrease. The deeper the depth of the water table, the effective stress of the soil increases. The depth of the ground water level affects the amount of excess pore pressure. The more shallow the depth of the ground water level, the amount of excess pore pressure will also increase even the value is positive. The deeper the depth of the ground water level, the greater the amount of excess pore pressure decreases even the value is negative.Key words : Prambanan Temple, effective stresses, excess pore pressureABSTRAKIndonesia yang secara geografis mempunyai wilayah yang terletak pada 6º LU sampai dengan 11 º LS serta 97º BT sampai dengan 141º BT merupakan daerah yang rawan terhadap gempa bumi.
