Advanced fibre optic sensor (crack detector) / Nurain Syuhana Muhamad Zaini and Anas Zafirol Abdullah Halim
Get PDFStructural defects such as cracks are one of the most critical issues that can arise at any phase of construction. Detecting concrete cracks may be difficult because they often occur beneath the surface. The use of fibre optic sensors was first introduced to detect cracks that occur in concrete. The aims of this innovation project are to develop an advanced fibre optic sensor design idea, assemble the prototype from the improvised design, demonstrate its performance, and assess its marketability potential. Secondary data collection methods were used to gather information from previous studies. Based on this research, it is noted that the efficiency of fibre optic sensors can be affected by various factors such as the expensive cost of fibre optic cables, even though they have the capability to detect cracks in buildings. By identifying these key problems, this study offers an opportunity to propose innovative solutions

Effect of zinc oxide on performance of ultrafiltration membrane for humic acid separation
No full textThe effects of different zinc oxide concentration on morphology, contact angle, surface roughness and rejection towards humic acid in polysulfone membrane were investigated. Flatsheet ultrafiltration membrane were prepared by using polysulfone as based polymer, polyethylene glycol as pore forming agent, zinc oxide as manipulated additive and TAP as compatibilizer. In this study, N, methyl-2-pyrrolidone were used as solvent and water as non solvent. The membrane were prepared via phase inversion method. Results showed that pure water flux was enhanced by the presence of zinc oxide up to 1 wt% and tend to decrease beyond this concentration. The increased pure water flux was attributed to the increase in hydrophilicity and surface roughness of membrane according to contact angle and AFM measurement. The rejection test with humic acid as solute revealed that by increasing zinc oxide concentration, rejection increases up to 98% at 2 wt% of zinc oxide. Therefore polysulfone/zinc oxide in this study can provide potential application for river water treatment which consist high humic acid concentration
Influence of inorganic additives on the performance of polysulfone ultrafiltration membrane
No full textThe influence of zinc oxide and silver (I) oxide in polysulfone ultrafiltration membrane was studied. The membranes were prepared via phase inversion method. The morphology, surface roughness, hydrophillicity and antibacterial properties of membrane were investigated using SEM, AFM and contact angle device consecutively. It was found that membrane with zinc oxide additive has excellent pure water flux as compared to silver (I) oxide. However silver (I) oxide has better humic acid rejection due to the tradeoff effect. SEM-EDX for PSf/silver (I) oxide reveals that the accumulation of silver on top area in cross section of membrane while for zinc oxide seems more concentrated on the bottom. Interestingly, the AFM results support the previous result when PSf/zinc oxide showed better surface roughness on the top of the membrane. Eventhough zinc oxide is known one of antibacterial material, however from qualitative experiment using disc diffusion test (e-coli), there is no inhibition ring for PSf/zinc oxide membrane as compared to membrane with PSf/silver (I) oxide membrane which shows excellence inhibition ring

Kata Kunci: Strategi Guru, Minat Belajar, Motivasi Belajar
Perubahan pola hidup modern dan derasnya arus globalisasi berdampak pada
rendahnya perhatian siswa terhadap pendidikan. Salah satu tantangan yang muncul
adalah menurunnya minat dan motivasi belajar, khususnya di kalangan remaja.
Peran guru sangat penting dalam merancang strategi pembelajaran yang tepat. Guru
tidak hanya dituntut untuk menyampaikan materi, tetapi juga menumbuhkan
semangat belajar siswa melalui pendekatan yang menarik dan bermakna. Penelitian
ini dilakukan untuk mengungkap strategi guru PAI dalam meningkatkan minat dan
motivasi belajar siswa di SMKN 1 Kras Kediri.
Fokus penelitian ini adalah (1) Perencanaan strategi guru PAI dalam
meningkatkan minat dan motivasi belajar siswa di SMKN 1 Kras Kediri. (2)
Pelaksanaan strategi guru PAI dalam meningkatkan minat dan motivasi belajar
siswa di SMKN 1 Kras Kediri. (3) Evaluasi strategi guru PAI dalam meningkatkan
minat dan motivasi belajar siswa di SMKN 1 Kras Kediri. Tujuan penelitian ini
adalah (1) untuk mendeskripsikan perencanaan strategi guru PAI dalam
meningkatkan minat dan motivasi belajar siswa di SMKN 1 Kras Kediri. (2) untuk
mendeskripsikan pelaksanaan strategi guru PAI dalam meningkatkan minat dan
motivasi belajar siswa di SMKN 1 Kras Kediri. (3) untuk mendeskripsikan
perencanaan strategi guru PAI dalam meningkatkan minat dan motivasi belajar
siswa di SMKN 1 Kras Kediri.
Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian
studi kasus. Sumber datanya yaitu, Kepala Selolah, Waka Kurikulum, Guru PAI,
dan Siswa. Teknik pengumpulan data menggunakan teknik observasi, wawancara
mendalam, dan dokumentasi. Analisis data dimulai dari kondensasi data, penyajian
data, dan penarikan kesimpulan. Sedangkan pengecekan keabsahan data
menggunakan peningkatan ketekunan, diskusi sejawat, dan triangulasi.
Hasil penelitian. Pertama, Guru menyusun strategi dengan
mempertimbangkan karakter siswa. Strategi yang digunakan dirancang agar lebih
komunikatif dan dekat dengan kehidupan siswa. Kedua, Pelaksanaan strategi guru
dilakukan melalui kegiatan pembiasaan religius, metode pembelajaran yang
variatif, serta penggunaan media pembelajaran interaktif. Strategi ini membuat
siswa menjadi lebih aktif, antusias, dan termotivasi dalam mengikuti pembelajaran
PAI. Ketiga, Evaluasi pembelajaran dilakukan melalui asesmen tertulis, tugas
kelompok, observasi kelas, serta pemanfaatan media digital seperti e-learning dan
Quizizz. Evaluasi mencakup aspek kognitif, afektif, dan psikomotorik siswa
