Abstract

The transmission system distributes electricity from power plants to substations before reaching consumers. During this process, obstacles such as power loss and voltage regulation occur, which must meet specific standards to prevent equipment damage. Power loss can result from factors like corona effects and insulator leakage. This study aims to analyze power loss and voltage regulation based on daily peak load data at 14:00 over 15 days, recording current and voltage values on the extra-high voltage Krian-Grati transmission network. This system uses ACSR Gannet conductors with a cross-sectional area of 392.84 mm² and a length of 79.41 km, having a resistance of 0.00086 Ω/km. Manual calculations for short transmission lines show a voltage difference between sending and receiving ends, with the sending voltage being slightly higher due to reactance, preventing a drastic voltage drop. Over 15 days in December 2024, voltage regulation did not exceed the standard maximum of <10%, with the highest recorded value at 4.7%. The highest power loss occurred on day 7 at 0.089 MW, while the lowest was on day 9 at 0.023 MW. The total power loss over 15 days reached 1.024 MW, with a daily average of 0.068 MW.

Abstract

PT. XYZ is a car mat manufacturing company in Surabaya facing challenges due to sharp, fluctuating client demands and uncertainties in material procurement. The bullwhip effect occurring within the company poses a high risk of raw material overstock mat, as well as stockout risks that can cause production downtime. This study aims to measure the existing bullwhip effect value, analyze material handling, and compare the effectiveness of quantitative forecasting methods under the Collaborative Planning, Forecasting, and Replenishment (CPFR) framework. Initial identification confirmed demand amplification, with bullwhip effect values of 1.349 in 2024 and 1.183 in 2025. Based on comparative accuracy testing for projecting the next 12 months' demand, the ARIMA (2,0,0) model was selected as the optimal method as it produced the minimum error value, with a Root Mean Squared Error (RMSE) of 2118.37 and a Mean Absolute Percentage Error (MAPE) of 7.93%. Utilizing this selected model, inventory control planning can be optimized, establishing the safety stock after forecasting at 3,978 units with a constant 1-month lead time.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh variasi Tip Nozzle airless spray terhadap ketebalan lapisan (Wet Film Thickness (WFT) dan Dry Film Thickness (DFT)), efisiensi penggunaan material coating melalui parameter Material Usage Rate (MUR) dan Film Thickness Utilization Index (FTUI), serta hubungan antara WFT dan DFT pada aplikasi epoxy coating Interseal 670HS pada material H-Beam SS400. Penelitian menggunakan metode eksperimen dengan tiga variasi Tip Nozzle, yaitu 217, 219, dan 517, sedangkan parameter penyemprotan seperti tekanan, jarak semprot, sudut aplikasi, operator, dan kondisi lingkungan dijaga konstan. Pengukuran WFT dilakukan menggunakan Wet Film Comb Gauge, sedangkan DFT diukur menggunakan coating thickness gauge. Data dianalisis menggunakan uji Shapiro-Wilk, Levene's Test, One-Way ANOVA, Kruskal-Wallis, Mann-Whitney U, serta regresi linear sederhana. Hasil penelitian menunjukkan bahwa variasi Tip Nozzle tidak memberikan pengaruh yang signifikan terhadap WFT (p = 0,578), tetapi memberikan pengaruh yang signifikan terhadap DFT (p = 0,038). Tip Nozzle 517 menghasilkan rata-rata WFT dan DFT tertinggi, sedangkan Tip Nozzle 217 menghasilkan DFT yang paling mendekati target 150 µm. Analisis efisiensi menunjukkan bahwa Tip Nozzle 219 memiliki nilai MUR tertinggi sebesar 47,8% dan efisiensi penggunaan cat sebesar 2,80 m²/L sehingga menjadi variasi nozzle yang paling efisien. Analisis regresi menunjukkan hubungan linier positif antara WFT dan DFT dengan persamaan DFT = 107,475 + 0,284(WFT), nilai koefisien korelasi R = 0,689, koefisien determinasi R² = 0,475, serta signifikansi p < 0,001, yang menunjukkan bahwa WFT berpengaruh nyata terhadap DFT. Hasil penelitian ini dapat menjadi dasar dalam pemilihan Tip Nozzle untuk memperoleh ketebalan lapisan yang memenuhi spesifikasi dengan penggunaan material coating yang lebih efisien.
