Abstract

Currently, environmental degradation caused by heavy metals has become a serious concern of many countries. To monitor the concentration of heavy metals in the environment, an in-situ sensor that can measure in real time and has high quality, sensitivity, and flexibility is essential. We proposed a modified multipath ring resonator (MPRR) based on silicon-on-insulator technology with additional gold nanodisk (GND) on top of the ring to increase its sensitivity. To prove the effect of GND on the sensitivity of the modified MPRR, finite-difference time-domain simulations were conducted. Results showed that the average sensitivity of the modified MPRR was 675 nm/RIU, where RIU corresponds to the refractive index unit, higher than that of the unmodified MPRR (171 nm/RIU). Moreover, compared with the single ring structure, the proposed design had better sensitivity. We believe that our proposed approach for the modification of MPRR is suitable for application to optical sensor development.

Abstract

Pengawasan perilaku dan mental terhadap anak sangat penting untuk dilakukan sebagai langkah preventif dari tindakan kriminal yang marak terjadi. Program pembangunan anak Indonesia termasuk ke dalam target bagian dari komitmen pemerintah dalam program Sustainable Development Goals (SDG’s). Komisi Perlindungan Anak Indonesia (KPAI) memandang bahwa salah satu pilar perlindungan anak ialah dalam ranah pendidikan ramah lingkungan namun sayangnya kasus pendidikan anak yang didominasi oleh kekerasan seksual dan perundungan menjadi marak terjadi. Dampak dari tindakan perundungan dapat mengubah perilaku dan mental anak sehingga memungkinkan terjadi tindakan kriminal. Perancangan pendeteksian bullying yang fokus pada jenis verbal bullying ditujukan sebagai bagian dari wujud partisipasi yang menentang keras tindakan perundungan. Perancangan sistem ini menggunakan Voice Recognition dengan metode natural language processing (NLP) yang diintergrasikan dengan sistem Internet of Things. Adapun komponen pendukung yang digunakan ialah Modul Recognition V3, Arduino Uno, NodeMCU-ESP32, MAX9814, dan SD Card Adapter Shield. Prinsip kerja dari sistem ini akan melakukan pendeteksian pada kata indikasi yang dikenali oleh modul Voice Recognition kemudian mengaktifkan proses perekaman dan penyimpanan audio suara kemudian mengirim data hasil rekaman audio pada sebuah database sehingga data dapat diakses dalam sebuah aplikasi smartphone. Persentase keterbacaan sistem dalam mendeteksi verbal bullying sebesar 67.81% dengan kesalahan rata-rata sistem sebesar 31.51%. Persentase proses perekaman audio dalam jangka waktu tertentu serta penyimpanan dan pengiriman data audio sampai ke server berhasil 100%. Perancangan sistem pendeteksi verbal bullying dan aplikasi smartphone telah berhasil dibuat dengan memanfaatkan sistem internet of things sebagai bagian dari inovasi pengembangan teknologi dalam upaya pengawasan dini terhadap intimidasi verbal bullying.

Abstract

A tsunami is a large sea wave caused by an earthquake or underwater landslide. Timely detection of tsunamis is critical to saving lives and minimizing damage to infrastructure. Radar has proven to be an effective tool for tsunami detection. This comprehensive review discusses the use of radar for tsunami detection. The two types of radar discussed are HF (High Frequency) radar and DART (Deep ocean Assessment and Reporting of Tsunamis) radar. HF radar can detect tsunamis from long distances in real-time. However, HF radar is susceptible to electromagnetic interference. The DART radar is specifically designed for deep sea tsunami detection. This radar provides real-time information about tsunami waves. However, the DART radar requires expensive marine infrastructure to install and operate. This review concludes that HF radar and DART radar have their respective advantages and disadvantages. The combination of both types of radar can provide a more comprehensive solution for tsunami detection. Further research is needed to improve the reliability of radar-based tsunami detection systems.

Abstract

Sekarang ini jumlah kendaraan meningkat dengan pesatnya, sementara sarana jalan masih tertinggal baik pertambahannya maupun kualitas jalan serta pemeliharaan, menyebabkan kemacetan lalu lintas sering terjadi dan jumlah kecelakaan kendaraan meningkat pula. Pengontrolan lalu lintas yang baik sangat dibutuhkan untuk efisiensi dan meningkatkan keselamatan pengguna jalan. Sebuah sensor radar doppler dapat digunakan untuk mendeteksi laju kecepatan relatif kendaraan, yakni antara mobil dan obstacle sehingga dapat digunakan untuk menghindari terjadinya kecelakaan dan dapat memantau kepadatan lalu lintas yang terjadi. Radar dirancang untuk kemudahan navigasi dan bisa digunakan untuk mendeteksi kecepatan suatu benda yang bergerak dengan cara mendeteksi energi dari suatu benda yang bergerak tersebut sekaligus menentukan posisinya. Dalam tulisan ini dibahas mengenai desain dan implementasi antena yang mampu mendukung aplikasi sensor radar doppler. Antena ini dirancang menggunakan antena mikrostrip dual beam yang bekerja pada frekuensi 10 GHz. Software yang digunakan untuk perancangan dan simulasi antena ini adalah Ansoft HFSS 10. Penelitian ini dimulai dengan menghitung dimensi antena sesuai rumus yang ada. Dimensi hasil perhitungan akan digunakan pada proses simulasi. Modifikasi dimensi antena digunakan sebagai cara untuk mendapatkan hasil yang optimum dalam simulasi, kemudian dimensi optimum tersebut digunakan dalam proses pabrikasi. Spesifikasi antena yang dibuat memiliki karakteristik bekerja pada frekuensi 10 GHz dengan bandwidth 60 MHz pada VSWR ≤ 1,5, serta memiliki gain sebesar 12,42 dBi.

Optical waveguides are the key component for distributing optical signals with very low propagation loss in optical communication. Several type optical waveguides are established currently such as silica optical fiber. In the planar structure, planar optical waveguides are suitable for implementing to integrated optic applications. In here, rectangular optical waveguides on a planar structure with a LiTaO3 crystal as the substrate are described. The optical waveguides were designed for single mode operation at infrared optical wavelength. The Marcatili method is used for designing by separated the rectangular optical waveguides into two slab optical waveguides.

Abstract

Optical waveguides are important for guiding lightwave from a place to other places. Propagation and insertion losses of the optical waveguides should be considered to be in low values. Recently, optical waveguides with circular structures, which are optical fibers, are used widely for guiding lightwave in long-distance optical communication with very low propagation and insertion losses. Simultaneously, optical waveguides with planar structure are also developed for short distance communication in optical devices. We have reported design and analysis of the planar optical waveguides. In this paper, fabrication of planar optical waveguides using a polyimide material on thin silicon dioxide combined with the silicon substrate is reported. The polyimide material is used for the core of the optical waveguides. The silicon dioxide located on the silicon substrate and the air is used for cladding of the optical waveguides. Fabrication of the optical waveguides such as oxidation, photoresist coating, masking, ultra-violet exposure, and etching was done. The fabricated optical waveguides were characterized physically using a standard microscope and scanning electron microscope (SEM). The fabrication processes and characterization results are reported and discussed in detail.

Abstract

Non Linear Frequency Modulation (NLFM) method can suppress the peak sidelobe level without additional windowing function. NLFM doesn’t require any weighting function because it has inbuilt one. NLFM has a variable frequency deviation function due to the relation between frequency and time of the signal which is not linear so that it is possible to suppress of peak sidelobe level. This paper studies the characteristic of various NLFM waveform, such as NLFM Tri Stage Piece Wise (TSPW), NLFM S, and NLFM Taylor. The study of Pulse Compression of NLFM waveform consists of three aspects. First, analysis of pulse compression performance. Second, analysis of background noise. Last, analysis of Doppler effects. The simulation is done using Matlab software. The lowest  value Peak Sidelobe Level (PSL)of NLFM TSPW is about -20 dB while NLFM S and NLFM Taylor are about -32 dB and -39 dB. Additive White Gaussian Noise (AWGN) and Doppler Effect influenced the value of PSL for each NLFM waveform. NLFM Taylor has the best NLFM waveform when the Doppler Effect and AWGN cause the value of PSL become high. Comparison between NLFM Taylor and Linear Frequency Modulation(LFM) is done in radar surveillance applications to analyze the detectability performance where the condition of Radar Cross Section (RCS) for each target has different significant value. The three targets are commercial airplanes, helicopter and fighter. For detectability performance, NLFM Taylor can detect more clearly than LFM conventional.
