Abstract

This article aims to design a model for forecasting the number of vehicles arriving at the battery swap station (BSS). In our case, we study the relevance of the proposed approach given the rapid increase in electric vehicle users in Indonesia. Due to the vehicle electrification program from the government of Indonesia and the lack of supporting infrastructure, forecasting battery swap demands is very important for charging schedules. Forecasting the number of vehicles is done using machine learning with the long short-term memory (LSTM) method. The method is used to predict sequential data because of its ability to review previous data in addition to the current input. The result of the forecasting using the LSTM method yields a prediction score using the root-mean-square error (RMSE) of 2.3079 x 10-6 . The forecasted data can be combined with the battery charging model to acquire predicted hourly battery availability that can be processed further for optimization and scheduling.

Abstract

Penelitian ini bertujuan untuk menguji pengaruh strategi coping terhadap kecenderungan relapse pada korban penyalahgunaan NAPZA (KPN) perempuan. Pendekatan kuantitatif digunakan dalam penelitian ini dengan melibatkan 43 responden dari tiga Institusi Penerima Wajib Lapor (IPWL) di Jawa Barat. Data dikumpulkan melalui angket, FGD, observasi, dan studi dokumentasi. Strategi coping diukur melalui dua dimensi, Problem Focused Coping (PFC) dan Emotional Focused Coping (EFC), sedangkan kecenderungan relapse diukur melalui lima aspek, seperti kecemasan dan dorongan untuk kembali menggunakan obat. Analisis data dilakukan dengan uji korelasi Pearson dan regresi linier berganda. Hasil penelitian menunjukkan bahwa mayoritas responden cenderung menggunakan strategi coping EFC (67,44%) dan memiliki kecenderungan relapse dalam kategori sedang (60,47%). Namun, uji regresi menunjukkan bahwa baik PFC maupun EFC tidak memiliki pengaruh signifikan terhadap kecenderungan relapse. Kesimpulannya, meskipun strategi coping digunakan oleh KPN perempuan, hal tersebut belum mampu secara signifikan mengurangi kecenderungan relapse. Hal ini mengindikasikan perlunya intervensi yang lebih efektif dan komprehensif untuk mendukung pemulihan KPN perempuan dari penyalahgunaan NAPZA.
