Ground Penetrating Radar (GPR) merupakan teknologi yang memanfaatkan gelombang radio untuk mendeteksi lokasi, kedalaman, dan bentuk objek yang terkubur di bawah permukaan bumi. Salah satu komponen penting pada sistem GPR yaitu antena, yang terdiri atas antena transmitter dan receiver. GPR bekerja pada berbagai band frekuensi, salah satunya pada frekuensi 1,6 GHz. Untuk dapat mendeteksi objek, antena yang dibutuhkan harus memiliki spesifikasi bandwidth yang lebar, pola pancar unidirectional, dan ringing level yang rendah. Perancangan menggunakan antena jenis bowtie antipodal dengan penambahan metode edge cutting dan matching impedance sebagai antena pemancar yang bekerja pada frekuensi 1,6 GHz. Perancangan disimulasikan menggunakan software dan difabrikasi dengan menggunakan bahan substrat FR-4 Eproxy. Hasil rancangan menunjukkan bahwa antena yang telah difabrikasi dan diuji dapat memenuhi spesifikasi yang diinginkan yaitu bandwidth sebesar 540 MHz pada rentang 1,32 GHz – 1,86 GHz, returnloss -16,38 dB, VSWR 1,35, gain 2,025 dBi dan pola radiasi bidirectional.

Pada proses pengiriman paket data pada suatu jaringan, tentu dibutuhkan arsitektur yang memiliki keandalan yang tinggi. Hal ini dibutuhkan agar dapat menjamin kecepatan pengiriman dan tidak adanya data yang gagal dikirimkan ke tujuan. Tersedianya banyak jalur tentu akan meningkatkan availability pada jaringan tersebut, namun tidak menjamin akan meningkatkan kecepatan atau kualitas pengiriman data dan keberhasilan data tersebut sampai ke tujuan. Adanya dua atau lebih jalur memungkinkan akan terjadinya penyebaran trafik yang tidak merata dan penumpukan trafik pada suatu gateway. Untuk menghindari hal ini, maka akan dilakukan metode Gateway Balancing. Pada penelitian ini dilakukan penerapan gateway balancing pada jaringan Software Defined Network menggunakan controller OpenDayLight dengan menerapkan dua algoritma scheduling yaitu algoritma Ant Colony Optimizaion dan algoritma Random Early Detection. Dengan menerapkan gateway balancing pada dua algoritma ini, maka akan dilakukan pengujian performansi trafik dengan mengalirkan UDP Flows. Parameter pengujian yang digunakan adalah Throughput, Delay, Jitter, dan Packeloss. Disimpulkan bahwa perfomansi trafik menggunakan gateway balancing dengan algortima Ant Colony Optimization menawarkan kecepatan data lebih baik dibandingkan algoritma Random Early Detection dengan selisih delay sebesar 4,46%. Sedangkan pada algoritma Random Early Detection, menghasilkan performa yang lebih baik pada keutuhan datanya, dengan selisih 3,55% pada throughput dan 5,85% pada packetloss yang dihasilkan.

This study aims to determine the process of utilizing Sidoarjo Mud (LUSI) as a substitute for paving blocks and to determine the results of the compressive strength test of using LUSI as a substitute for paving blocks. The LUSI substitution is expected to be able to provide innovations in the construction of a paving block mixture. The research method used is the experimental method. The manufacture of test objects starts from the preparation stage, mix design, manufacture of test objects, testing and classifying paving blocks according to SNI 03-0691-1996. The sample of specimens used normal mix design and mix design substitute LUSI 40% of the fine aggregate value. Based on the results of research, paving blocks with a normal mix design of 1Pc: 2Ps are classified as quality A, 1Pc: 3Ps and 1Pc: 4Ps are classified as B quality, while for paving blocks substituting LUSI in a mixture of 1Pc: 2Ps is classified as quality B, for a mixture of 1Pc: 3Ps and 1Pc : 4Ps is classified as C quality.

In determining the price of a job, it need the basic tool of unit price analysis, namely the construction costs analysis. In calculating the construction costs analysis there are several methods have been generally used such as analysis of BOW, SNI and also companies that make their own calculation analysis. A comparative study is needed from the three methods so that it can be seen which is more effective and efficient as a basis for all parties in determining the strategy in terms of cost budget estimates. The study was conducted by preparing a project cost budget plan based on the volume of works on the bill of quantity (BoQ). The unit price analysis is calculated based on BOW analysis, SNI analysis and Contractor version analysis. From the estimation results, a price based on BOW analysis is IDR 2,682,315,013,-, based on SNI analysis is IDR 1,958,002,381, - and based on analysis of contractor calculations is IDR 1,781,956,483. Differences in price between BOW and SNI is IDR 724,312,632. Differences in price between BOW and contractors calculation is IDR 900,358,529.

In the development of power amplifiers, MOSFETs are widely used in the composition of the manufacture. As is known, MOSFETs have a longer on-off time loss compared to IGBT. The loss on the on-off time has an impact on the heat generated by the MOSFET. Class D Audio Amplifier is basically a Switching-Amplifier or Pulse Width Modulation-Amplifier. High efficiency means that it will produce low power dissipation, thus the power wasted is relatively lower when compared to class A, B or AB amplifiers. Because the class D audio amplifier can be said to be more economical because it does not require a large heatsink and a large power supply. The manufacture of the Class D power amplifier system uses a voltage of 28.5 volts DC on the final transistor IRF9530 AND IRF630 measuring the input transistors of 3.3 volts DC, 28.5 volts DC. In the test using an oscilloscope type LS 8050, 50 MHz frequency, the position of the audio input off of the amplifier has sound defects. Testing of the power amplifier is carried out when the treble on the input tone control is full db in the defective amplifier wave.

It is common knowledge that CNN is a significant method in image classification. This is because CNN can classify Latin letters with a high degree of accuracy. Lenet5 in CNN is tasked with converting 2D features from an image into a convolutional network continuously. CNN architecture consists of several layers, including the Convolution Layer, Relu layer, Subsampling layer, Fully Connected Layer. In this research, CNN is used to classify Javanese script images into 20 classes. These classes include ha, na, ca, ra, ka, da, ta, wa, la, pa, dha, ja, yes, nya, ma, ga, ba, tha, nga. Javanese script used in this research is Ngalena Javanese script. The precision values for each class range from 0.5 to 0.6.
