Abstract

Jumlah permintaan dan persediaan pada lingkup produksi tidak memiliki tren data sehingga bersifat kabur. Pengoptimalan jumlah produksi merupakan salah satu solusi dalam mengatasi terjadinya kerugian. Metode Mamdani dan Metode Sugeno adalah metode yang dapat digunakan untuk mengoptimalkan jumlah produksi barang. Penelitian ini menganalisis perbandingan metode Mamdani dan metode Sugeno pada kasus produksi. Digunakan dua kasus yang berbeda untuk melakukan perbandingan tingkat keakuratannya dan diperoleh dengan penghitungan MAPE. Pada kasus 1 yaitu produksi roti metode yang lebih akurat adalah metode Mamdani dan kasus 2 yaitu produksi eggroll metode yang lebih akurat adalah metode Sugeno. Penelitian ini menghasilkan bahwa terjadinya perbedaan hasil keakuratan metode pada dua kasus yang dibahas bergantung pada karakteristik data, jenis distribusi, dan pembentukan aturan pada setiap kasus. Hasil penelitian tersebut memberikan efisiensi waktu dalam memilih metode dengan tingkat error terendah dalam mengoptimalkan produksi barang.

Abstract

Peramalan nilai tukar mata uang merupakan aspek penting dalam analisis ekonomi karena fluktuasi nilai tukar dapat mempengaruhi berbagai sektor ekonomi suatu negara, termasuk perdagangan internasional, investasi, dan kebijakan moneter. Indonesia, sebagai negara dengan perekonomian terbuka, sangat rentan terhadap dinamika ekonomi global. Oleh karena itu, memahami dan memproyeksi pergerakan nilai tukar mata uang menjadi krusial untuk perencanaan ekonomi dan pengambilan keputusan yang lebih baik. Penelitian ini bertujuan untuk memproyeksi harga beli nilai tukar Rupiah terhadap Yuan, Dollar Amerika, dan Dollar Singapura pada bulan Januari-Februari 2024 menggunakan metode Fuzzy Time Series Markov Chain dengan data historis tahun 2023. Metode ini menggunakan dua fungsi keanggotaan yakni sigmoid dan gauss untuk menangani kompleksitas data, karena kemampuannya untuk merepresentasikan tingkat keanggotaan dan menangkap perubahan secara lebih halus antara keanggotaan rendah dan tinggi. Hasil penelitian menunjukkan kinerja yang baik dengan error prediksi rendah (0-10%). Hasil Mean Absolute Percentage Error (MAPE) dengan metode FTS-Markov Chain untuk ketiga nilai tukar yakni Yuan, Dollar Amerika dan Dollar Singapura dengan fungsi keanggotaan sigmoid 1,127% sedangkan fungsi keanggotaan gauss 2,435%. Nilai tukar Rupiah terhadap Yuan mengalami fluktuasi, terhadap Dollar Amerika diprediksi mengalami apresiasi, dan terhadap Dollar Singapura mengalami penurunan awal namun meningkat kembali.

Abstract

Penjadwalan perkuliahan yang efektif dan efisien merupakan tantangan utama karrena kompleksitas mengatur waktu, ruang, dan dosen yang sesuai dengan berbagai mata kuuliah dan jumlah mahasiswa. Algoritma genetika dipilih karena kemampuannya dalam mencari solusi optimal melaui proses seleksi, crossover, dan mutasi. Penelitian ini dimulai dengan pembuatan populasi awal secara acak dan dilanjutkan dengan evaluasi berdasarkan fungsi tujuan yang mempertimbangkan konflik yang terjadi. Proses seleksi digunakan untuk memilih individu-individu terbaik yang akan menjadi orang tua bagi generasi berikutnya.Crossover dan mutasi diterapkan untuk menghasilkan variasi dalam populasi, diikuti oleh mekanisme perbaikan (GeneRepair) untuk memastikan semua solusi yang dihasilkan valid dan layak. Hasil penelitian ini menunjukkan bahwa algoritma genetika dapat menghasilkan jadwal perkuliahan yang lebih optimal dibandingkan dengan metode tradisional, dengan mengurangi jumlah konflik dan meningkatkan efisiensi penggunaan ruang dan waktu. Implementasi ini diharapkan dapat membantu pihak administrasi universitas dalam mengelola penjadwalan perkuliahan secara lebih efektif dan efisien.

Abstract

Using a variety of criteria, group decision-making is a popular method for rating possibilities. Here, we assess each choice based on the same standards. AHP and VIKOR techniques have been proposed to address the problem of creating detours to the historical tourism attractions of Medan City. This study modifies the VIKOR technique to identify a feasible solution while evaluating options with both narrow and broad requirements. This study provides numerical examples based on case studies to illustrate the application of the proposed model and assess the effectiveness of this approach modification. The results show that the updated strategy is effective and realistic.
