Analisis Daya Dukung Pondasi Spun Pile Dievaluasi Dengan Kalendering Dan PDA
Get PDFIn a bridge construction project, there are two types of structures, namely the superstructure and the substructure. The foundation is part of the substructure that functions as the main support and the most important part that greatly affects the stability of the building above it. In foundation design, it is required to calculate the bearing capacity. The bearing capacity of the foundation can be predicted based on soil investigation data which compared by actual field dynamic test data. Dynamic test is carried out to determine the actual bearing capacity after pile installation. This research aims to predict of spun pile bearing capacity and settlement based on N-SPT data, then evaluated by dynamic test (PDA and calendering) at “X” Toll Road Construction Project. Moreover, an evaluation of the axial bearing capacity of single and group piles will be carried out against the workloads. The results shows that prediction of the bearing capacity closest to the PDA data using Luciano Decourt Method (1987) around 309.45 tons with a difference of 4.20% each other. Calendering analysis by Gates Method found that 301.46 tons with a difference of 50.8% against the prediction. The prediction of immediate settlement is obtained of 26.79 mm smaller than PDA result and a difference of 13.30%. The results of the evaluation of the axial bearing capacity of single and group piles against workloads show that both the predicted and actual (PDA and calendering) bearing capacity is greater than the workload.Dalam suatu proyek konstruksi jembatan, terdapat dua jenis struktur, yaitu struktur atas dan struktur bawah. Pondasi merupakan bagian dari struktur bawah yang berfungsi sebagai pendukung utama dan bagian terpenting yang sangat berpengaruh terhadap kestabilan bangunan di atasnya. Dalam perencanaan pondasi diperlukan perhitungan daya dukungnya. Daya dukung pondasi dapat diprediksi berdasarkan data penyelidikan tanah yang kemudian dibandingkan dengan data pengujian dinamis di lapangan. Pengujian dinamis dilakukan untuk mengetahui daya dukung aktual tiang yang terpasang. Penelitian ini bertujuan untuk memprediksi daya dukung dan penurunan spun pile berdasarkan data N-SPT, kemudian dievaluasi dengan pengujian dinamis (PDA dan kalendering) pada proyek Pembangunan Jalan Tol “X”. Selain itu akan dilakukan evaluasi ketahanan daya dukung aksial tiang tunggal maupun grup terhadap beban yang bekerja pada pondasi. Hasil penelitian menunjukan bahwa prediksi daya dukung yang paling mendekati PDA terdapat pada Metode Luciano Decourt (1987) yaitu 309,45 ton dengan selisih sebesar 4,20%. Daya dukung hasil kalendering dengan Metode Gates yaitu 301,46 ton dengan selisih sebesar 50,8% dari prediksi. Hasil prediksi penurunan segera diperoleh sebesar 26,79 mm lebih kecil dari PDA dengan selisih sebesar 13,30%. Hasil evaluasi ketahanan daya dukung aksial tiang tunggal maupun grup terhadap beban kerja didapat bahwa baik daya dukung prediksi maupun aktual (PDA dan kalendering) daya dukungnya lebih besar dibandingkan dengan beban kerja
Prediksi Penggunaan Obat Peserta Jaminan Kesehatan Nasional Menggunakan Algoritma Naïve Bayes Classifier
Get PDFCurrently, most of the patients seeking treatment at the hospital use the National Health Insurance (JKN) organized by the Healthcare and Social Security Agency (BPJS Kesehatan). In some hospitals, the figure is above 80%. Considering the very high number of BPJS Kesehatan participant seeking treatment at the hospital, a good data management method is needed, especially regarding the management of drug. Drug supply needs to be analyzed from time to time so that it can help predict future needs. An adequate supply of drugs and as needed is one of the things that affect service to patients. The availability of sufficient stock is expected to accelerate service to patients so that they do not have to wait long. Patients who are served quickly are expected to be satisfied. The impact of this patient satisfaction will increase the number of patient visits to the hospital. To support this, it is necessary to create a system that can estimate drug needs. The system can predict drug demand by using drug sales data to JKN participant patients for five years. Drug data used as research samples and then processed using an algorithm is the Naive Bayes Classifier. The Naive Bayes Classifier method is a method used to predict future opportunities using the basis of previous experience. A distinctive feature of this method is that it uses a very strong assumption of the independence of each event. While software testing uses the User Acceptance Test (UAT) model. Based on testing using this method, the system can be well received by users with a score of 78.64% (good).

PENGARUH PERENDAMAN NACL DAN NAOH PADA PEMBUATAN KOMPOSIT SERAT PINANG DENGAN METODE VACCUM BAGGING
Get PDFComposites are widely used in household appliances, as well as in the industrial sector. This is because composites have several advantages such as composite materials are stronger, more flexible and also resistant to corrosion. At this time betel nut is already used in the medical and cosmetic fields. However, the consequences of this processing still leave waste in the form of betel nut fiber. Such potential can be used as fibers in the manufacture of composites. The manufacture of composites this time uses lycal resin as a matrix and uses the vaccum bagging method. This study aims to determine the technical analysis and mechanical properties of making betel nut fiber composites to obtain tensile and bending strength results. The tensile test refers to ASTM D-638 and the bending test refers to ASTM D 790. In the NaCl immersion variation, the highest tensile value was obtained, namely 21.78 MPa, and in the NaOH immersion variation, the highest tensile value was obtained, which was 30.21 MPa. in the bending test the Immersion variation NaCl got the highest bending strength value with a value of 509.58 MPa and for the immersion variation NaOH got the highest bending strength value with a value of 555.82 MPaKomposit banyak digunakan dalam peralatan rumah tangga, dan juga di sektor industri.
