Abstract

Electromagnetic radar technology has become integral in various innovations, such as military, air navigation, and weather monitoring. However, the ability of radar to detect objects accurately creates vulnerability to detection by other parties, raising security and confidentiality issues. Therefore, the development of electromagnetic absorber material technology is becoming increasingly important, especially in the military. One promising effort is using smart magnetic pigments as electromagnetic wave absorber materials. This material can be synthesized from metal waste and iron sand, which have high permeability and permittivity. However, synthesizing effective and economical smart magnetic materials is still challenging. Iron sand is one of the potentially abundant material solutions. This study aims to synthesize and characterize smart magnetic pigments ( ) from iron sand and silica ( ) from water hyacinth ash as electromagnetic wave absorber materials. The methods used include the extraction of silica from water hyacinth by a slow heating method at high temperatures and the synthesis of magnetite from iron sand by the coprecipitation method. The resulting material was then composited into an Unsaturated Polyester Resin (UPR) matrix and tested for electromagnetic wave absorption. The developed composite material has a porous structure (3.63 µm, porosity 15.746%) with synergistic properties between dielectric and   ferromagnetic. The Si-O-Si and Fe-O functional groups (FTIR) and the crystal phases , Cristobalite, and Butlerite (XRD) strengthen the material interactions. This combination of characteristics proves that the composite material can absorb and dampen electromagnetic waves.

Abstract

This research was conducted to analyze the Mg doping concentration effect on the structure, morphology, and optical properties of ZnO thin film prepared using the sol gel spin coating method. The Mg concentration was varied in the mole fraction of 1%, 3%, and 5%. Firstly, ZnO: Mg solution was dropped on a substrate and grown with a rotating speed of 3000 rpm and then annealed at 500 °C for 2 hours. The characterization of thin films' structure, morphology, and optical properties was done using XRD, FESEM, EDX, and UV-VIS spectrophotometer. XRD result showed a polycrystalline structure with three dominant peaks of (100), (002), and (101) plane, hexagonal wurtzite structures. Furthermore, the crystallite size was increased with the increase of Mg doping. FESEM results showed that the 5% ZnO: Mg thin film was the densest and least void from other films. In addition, the results of UV-Vis-NIR analysis showed the highest absorption value at a wavelength of 360-370 nm. The bandgap energy increased at 1% and 3% Mg doping samples but decreased by 5% Mg doping comes from the excess of oxygen in thin film with 5% Mg doping.

Abstract

This study presents the design, fabrication, and performance evaluation of a sine S-bend embedded square-core optical waveguide for temperature sensing applications. The waveguide was fabricated using a straightforward and cost-effective CNC milling technique, with PMMA as the cladding and unsaturated polyester resin (UPR) as the core material. Three different bend heights (0.5 cm, 0.6 cm, and 0.7 cm) were investigated to assess their effects on sensor sensitivity, response time, accuracy, and hysteresis. Results showed that increasing the bend height enhanced the sensor sensitivity, with the highest sensitivity of 0.0283 dB/°C achieved at a bend height of 0.7 cm. The response time was consistently maintained at approximately 40 seconds across all samples. The sensor exhibited excellent accuracy, reaching up to 99.31% at a bend height of 0.5 cm. The maximum hysteresis observed was 0.202 % at a bend height of 0.7 cm, indicating stable performance during thermal cycling. These results confirm that the integration of a sine S-bend structure, smooth core surface, and precise waveguide dimensions can significantly improve sensor performance while maintaining a simple and scalable fabrication process.

Abstract

Simulasi adalah sebuah pemodelan secara sederhana yang dirancang untuk mengetahui dan memahami suatu permasalahan yang akan diselesaikan. Sebelum melakukan kegiatan riset, seorang peneliti terlebih dahulu membuat hipotesis eksperiment. Dalam membuat hipotesis eksperiment diperlukan pendekatan secara numerik, atau komputasi. Dua pendekatan ini bertujuan untuk memberi gambaran atau simulasi experiment yaitu dapat memodelkan suatu permasalahan. Salah satu experiment yang sedang banyak dikembangkan oleh peneliti yaitu experiment waveguide. Riset waveguide adalah salah satu riset yang banyak dikembang pada sensor yang memerlukan karakteristik material, dan indeks bias yang tepat guna menciptakan sensor yang mempunyai tingkat akurasi yang tinggi, sensitifitas yang sensitif, dan nilai loss yang kecil. Salah satu material yang sering digunakan pada riset waveguide adalah material SiO2 dan TiO2. Oleh karena itu pada riset ini dicari perbandingan loss daya pada material SiO2 dan TiO2, selain itu Parameter yang menyebabkan tinggi loss daya pada Waveguide dan cara mengatasi tinggi loss daya pada waveguide. Riset ini dilakukan dengan tahap yaitu tahap analisis permasalahan dan tahap pemprogaman komputer. Dengan tahapan yang dilakukan maka riset ini menghasilkan. Waveguide loss use material SiO2: 1.11% Waveguide loss use material TiO2: 2.90% New value of alpha: 0.05; Waveguide loss use material SiO2: 1.16% Waveguide loss use material TiO2: 4.35%; Waveguide loss use material SiO2: 2.22% Waveguide loss use material TiO2: 5.80% New value of alpha: 0.15; New value of alpha: 0.10; Waveguide loss use material SiO2: 2.78% Waveguide loss use material TiO2: 7.25% New value of alpha: 0.20; Waveguide loss use material SiO2: 3.33% Waveguide loss use material TiO2: 8.70% New value of alpha: 0.25; Waveguide loss use material SiO2: 3.89% Waveguide loss use material TiO2: 10.15% New value of alpha: 0.30. Pada data yang didapat kami melakukan variasi pada sudut alpha yaitu sebanyak six variasi dengan setiap variasi berselisih five dimulai dari 0.10 hingga 0.30. Hasil tersebut menunjukan bahwa Perbandingan loss material SiO2 dan TiO2 bernilai sama dan parameter yang mempengaruhinya yaitu sudut alpha datang nya gelombang cahaya, hal ini kita dapat atasi untuk mengurangi daya loss dengan cara mengecilkan sudut alpha dibandingkan sudut kritis nya sehingga gelombang cahaya yang terpantul-pantul pada waveguide tidak keluar pada jalur nya dan mengakibatkan Loss daya.

Abstract

Coldstorage adalah ruangan yang dirancang sedemikian rupa agar dapat mempertahankan tingkat suhu tertentu, yang dibuat dengan tujuan untuk menaruh bermacam produk bahan makanan dan lain sebagainya agar kesegarannya dapat bertahan lebih lama. Sistem Pendingin (Refrigeration system) atau sistem refrigerasi merupakan suatu sistem yang dapat menurunkan dan menjaga temperature ruangan atau material tertentu menjadi lebih rendah temperaturnya dari pada temperatur lingkungan. Yaitu dengan cara memindahkan panas kalor dari ruang/material tersebut ke luar sistem atau ruangan yang lain. Coeffisien of Performance (COP) merupakan suatu nilai perbandingan antara kapasitas penyerapan panas yang terjadi dievaporator dengan sejumlah kerja kompresi yang dilakukan di kompresor. Nilai COP merupakan nilai COP aktual atau yang sebenarnya terjadi. COP carnot, merupakan nilai COP yang ideal dengan menganggap bahwa kalor yang dilepas di kondensor adalah sama dengan kalor yang diambil di evaporator ditambah energi yang dikeluarkan di kompresor. Efisiensi refrigerasi adalah perbandingan antara Coefficent of Performance Actual dan Coefficent of Performance Carnot. Efisiensi refrigerasi juga menunjukkan kedekatan sistem atau siklus pendingin tersebut dengan siklus ideal yang mampu-balik, yaitu siklus Carnot. Dengan Nilai COP aktual sebesar 4.33 dan Nilai COP carnot 4,52 dan efisiensi refrigerasi sebesar 96 %, maka ruang pendingin Cold Storage sudah dimanfaatkan dengan baik

Abstract

The use of technology in using the learning media becomes a matter for teachers because it plays an important role in achieving learning goals. Technology is applied in education as learning media videos in learning process in classroom. The research aims were (1) analysis the use, (2) finding the positive impacts, and (3) finding the inhibitor factors in learning videos as virtual learning media on physics subjects for high school students in Pacitan Regency. The study used a qualitative-descriptive method using the data-collection technique: centralized interviews. The results of the study revealed that (1) the way high school teachers teach media in Pacitan Regency was mostly the same, id est explaining the key points of the material that would be presented through the video, dividing students into small groups and allowing them to discuss and communicate with each other, as well as sharing ideas and thoughts with their group mates, and then concluded with a confirmation and a clarification of the students' conceptual understanding. (2) There were several positive impacts from the use of a learning video media that is helpful teachers and students in the teaching process, that is students became more interested in the lesson material presented, and students became more active due to the learning process using group discussion methods, which led to increase enthusiasm. (3) There were also several inhibitors from the use of learning video media, i.e. some teachers not being tech-capable, which likely caused difficulties in operating the tools and facilities and infrastructure provided by the school were still incomplete or might not have been available at all.
