ABSTRAKPenelitian ini bertujuan untuk memprediksi tingkat konsumsi gas pipa domestik di
Indonesia menggunakan metode Neural Network, ARIMAX, dan Multiple Linear
Regression (MLR). Peramalan dilakukan hingga periode Desember 2025 dengan
menggunakan data historis tingkat konsumsi gas pipa domestik, inflasi, selisih
harga minyak dan gas, serta selisih harga batubara dan gas periode Januari 2007
sampai dengan September 2012 sebagai prediktor. Hasilnya metode ARIMAX
memberikan hasil yang paling akurat dengan nilai MAPE 3.89%. Metode Neural
Network memberikan hasil forecasting dengan nilai MAPE 6.34%, sedangkan
metode MLR mempunyai tingkat error terbesar dengan MAPE 8.39%. Kapasitas
produksi gas Indonesia cukup besar, tetapi jumlah gas yang dikonsumsi untuk
keperluan domestik masih tergolong sedikit. Hasil forecasting ketiga metode
menunjukkan ke depannya tingkat konsumsi gas akan terus meningkat.
Perbandingan antara hasil forecasting ketiga metode dan Neraca Gas Indonesia
cukup besar. Hal ini menunjukkan meskipun Indonesia memiliki potensi
cadangan gas alam yang sangat melimpah, tetapi permintaan domestik belum
terpenuhi secara maksimal.
ABSTRACTThis study aims to predict the level of domestic pipeline gas consumption in
Indonesia using Neural Network, ARIMAX, and Multiple Linear Regression
(MLR). Forecasting is done until the period of December 2025 using historical
data of domestic pipeline consumption rate, inflation, the difference price of oil
and gas, as well as the difference price of coal and gas from the period January
2007 until September 2012 as predictor. The result ARIMAX method gives the
most accurate results with the value of MAPE 3.89%. Neural Network method
gives forecasting result with MAPE 6.34%, while the MLR method has the largest
error rate with MAPE 8.39%. Indonesia gas production capacity is quite large, but
the amount of gas consumed for domestic use is still relatively small. The third
method of forecasting results indicate the future gas consumption will continue to
increase. Comparison between the results of the three forecasting methods and
Neraca Gas Indonesia is quite large. This shows even though Indonesia has very
abundant potential reserves of natural gas, but domestic demand has not been met
maximally.
