Pushover Analysis of Harvard Dormitory Thursina International Islamic Boarding School Building with Inter Story Isolated System Modification
Get PDFRecently the demands of additional building functions have varied. These demands tend to affect structure stability because of the effects of additional mass. For example, Harvard Dormitory Thursina International Islamic Boarding School, located in Dau region, Malang city, East Java, Indonesia, a 11 x 8 m2 swimming pool is relocated on 4th floor. A big mass of pool certainly performs bigger lateral force due to seismic behaviour of structure itself. To reduce that, the IIS method is installed on the 3rd floor as it has damper effect along X and Y axis that is provided by LRB spring systems. IIS is widely used mainly in Japanese high-rise structures such as Shiodome Sumitomo building and Umeda Tower. To analyse the IIS modified structure, it is performed pushover analysis as controlled deformation is stated 18 in at rooftop. The results showed that 465 kN shear force and 160 mm story drift occurred on the 3rd floor which is the largest value compared to other stories. It is also obtained 230 mm lateral deflection of rooftop as the first plastic hinges are formed

No full textOptimasi Peningkatan Kontras Gambar Menggunakan Interval-Valued Intuitionistic Fuzzy Sets dan Contrast Limited Adaptive Histogram Equalization (CLAHE)
Get PDFPengolahan citra merupakan bidang yang terus berkembang seiring dengan kemajuan teknologi komputer, dengan fokus utama pada peningkatan kualitas gambar, terutama pada gambar yang memiliki kontras rendah. Salah satu tantangan yang sering dihadapi adalah kesulitan dalam mengidentifikasi detail pada gambar yang memiliki pencahayaan yang kurang optimal atau kontras yang tidak memadai. Penelitian ini mengusulkan suatu pendekatan hibrida yang menggabungkan Interval-Valued Intuitionistic Fuzzy Sets (IVIFS) dan Contrast Limited Adaptive Histogram Equalization (CLAHE) untuk meningkatkan kontras gambar. IVIFS berperan dalam mengatasi ketidakpastian yang terdapat dalam intensitas piksel, sedangkan CLAHE dirancang untuk meningkatkan kontras lokal tanpa menyebabkan efek over-enhancement atau noise yang berlebihan. Dataset gambar dengan kontras rendah diambil dari Kaggle untuk menguji efektivitas metode yang diusulkan. Hasil pengujian entropi menunjukkan bahwa metode CLAHE menghasilkan nilai entropi tertinggi pada seluruh gambar, yang mencerminkan peningkatan signifikan dalam detail dan kontras. Proses defuzzifikasi menghasilkan gambar dengan entropi yang lebih halus, memberikan kontras yang optimal tanpa distorsi yang berlebihan. Metode yang diusulkan terbukti lebih efektif dibandingkan dengan teknik tradisional seperti Histogram Equalization (HE) dan Adaptive Histogram Equalization (AHE). Pendekatan ini menawarkan solusi yang efisien dan optimal untuk peningkatan kualitas citra, khususnya dalam aplikasi citra medis, penginderaan jauh, dan pengolahan citra lainnya

Deteksi Lonjakan Listrik Menggunakan Metode Diferensiasi Numerik
Get PDFPengelolaan konsumsi energi listrik rumah tangga menjadi tantangan penting dalam mencapai efisiensi energi dan keberlanjutan lingkungan. Penelitian ini bertujuan untuk mendeteksi lonjakan konsumsi energi listrik menggunakan metode diferensiasi numerik. Dataset yang digunakan berasal dari data konsumsi listrik rumah tangga publik dengan parameter seperti daya aktif, daya reaktif, tegangan, dan intensitas arus. Data diolah melalui proses pembersihan, konversi tipe data, dan penanganan nilai kosong sebelum dilakukan analisis. Diferensiasi numerik diterapkan untuk menghitung perubahan konsumsi energi antar waktu, dengan ambang batas yang ditentukan berdasarkan dua kali standar deviasi dari distribusi perubahan daya. Hasil penelitian menunjukkan bahwa lonjakan konsumsi energi tidak bersifat acak, melainkan memiliki pola temporal tertentu yang berkaitan dengan aktivitas rumah tangga. Visualisasi scatter plot memberikan wawasan penting mengenai intensitas dan distribusi lonjakan, membantu identifikasi pola konsumsi energi yang efisien. Penelitian ini berkontribusi pada pengembangan sistem pemantauan energi rumah tangga yang proaktif untuk mendukung pengelolaan energi yang berkelanjutan
