Analisis Ekspor Kopi Menggunakan Clustering K-Means dan Davies-Bouldin Index
Get PDFIndonesia merupakan salah satu produsen kopi terbesar di dunia, sehingga sektor ekspor menjadi pilar penting dalam perekonomian nasional. Aktivitas ekspor berperan dalam meningkatkan keuntungan, memperluas pangsa pasar, serta menjaga kestabilan harga komoditas dan nilai tukar. Penelitian ini mengkaji penerapan metode K-Means Clustering untuk menganalisis kinerja ekspor kopi berdasarkan negara tujuan. Data penelitian diperoleh dari catatan ekspor perusahaan Café Coffee pada periode 2023–2024, mencakup 40 negara tujuan beserta total kuantitas ekspor. Pengolahan data dilakukan melalui teknik data mining clustering dengan ukuran jarak Euclidean Distance. Hasil analisis menunjukkan bahwa algoritma K-Means berhasil mengelompokkan laba ekspor ke dalam tiga kategori, yaitu laba rendah, sedang, dan tinggi. Validasi model dilakukan menggunakan Davies-Bouldin Index (DBI) dengan nilai 0,422, yang mengindikasikan kualitas klaster yang baik dan dapat diterima

Tijorat Banklari Kreditlarining Daromadliligini Ta'minlashning Dolzarb Masalalari
Get PDFXalqaro bank amaliyotida tijorat banklarining rentabelligini ta'minlash muhim ahamiyatga ega bo‘lib, bu nafaqat ularning moliyaviy barqarorligini saqlashga, balki bozor sharoitida raqobatbardoshligini oshirishga ham xizmat qiladi. Rentabellik darajasi yuqori bo‘lgan banklar o‘z moliyaviy vositachilik funksiyasini samaraliroq bajaradi, bu esa ularning iqtisodiyotdagi o‘rni va rolining mustahkamlanishiga olib keladi. Shu bois, dunyoning rivojlangan g‘arb davlatlari amaliyotida tijorat banklarining rentabelligini oshirish va barqarorligini ta'minlash masalalari moliya bozorida ularning raqobatbardoshligini kuchaytirishning eng ustuvor va dolzarb yo‘nalishlaridan biri sifatida ko‘riladi. Ular banklarning samarali faoliyat yuritishi, mijozlarga yuqori sifatli xizmat ko‘rsatishi hamda iqtisodiy rivojlanishga munosib hissa qo‘shishini ta'minlash uchun rentabellikni oshirishga katta e'tibor qaratadilar. Maqolada mamlakat tijorat banklari kreditlarining daromadliligini ta'minlashga qaratilgan ilmiy takliflar ishlab chiqilgan
Analysis of Fire-resistant Properties of A Fireproof Composition
Get PDFThe study investigates the development of modified liquid-glass compositions for fire protection of buildings and structures—one of the significant challenges in modern construction. The main aim of the research was to determine optimal modification parameters of liquid glass compositions by incorporating ethylene glycol-urea-formaldehyde (EGUF) oligomers to enhance fire-resistant properties. During the study, EGUF oligomers were synthesized at temperatures ranging from 120 to 140 °C in an alkaline medium. Liquid-glass mixtures containing various concentrations (from 1% to 10%) of these oligomers, which preserved urethane groups in their structure, were prepared and tested for stability under high-temperature conditions using a digital electronic device. The results demonstrated that increasing the concentration of EGUF oligomers (particularly from 6% to 10%) significantly improved the thermal stability of liquid glass. Specifically, compositions prepared with a 10% concentration maintained stability over extended periods at temperatures of 800 °C and above. Compared to traditional fireproof coatings, these modified compositions exhibited superior thermal stability, ease of application, environmental safety, and improved adhesion to various construction materials. In conclusion, liquid glass modified with EGUF oligomers effectively provides fire protection in modern construction practices. Future research aimed at expanding local raw-material sources and refining this technology could enhance economic efficiency and broaden its practical application

Suspended Sediment Amount Estimation in River Using Anfis and Conventional Methods
Get PDFThe amount of sediment in rivers is of great importance in terms of determining the amount of pollution, river transport, dam life and other factors. In this study, the sediment matter in river was estimated using Multiple Linear Regression (MLR), Sediment Rating Curve (SRC) and Adaptive Neuro-Fuzzy Inference System (ANFIS) methods. For sediment estimation, models were developed using the flow and precipitation data between the years 2014-2022 as input parameters from a station on the Yahara River near Catonsville, United States. The models were evaluated using both graphical and statistical analyses. Performance comparison between prediction models was conducted using three key criteria: coefficient of correlation (R), root mean square error (RMSE), and mean absolute error (MAE). Based on these evaluation metrics, the ANFIS model demonstrated superior performance compared to other models in predicting suspended sediment amount in the river
