Abstract

Ketergantungan ekonomi masyarakat di kawasan PLBN Entikong terhadap produk Malaysia serta tingginya perdagangan informal lintas batas menyebabkan arus devisa keluar dan masuk tidak tercatat secara resmi. Selain itu, perbedaan harga barang dan mobilitas wisatawan lintas batas berpotensi menimbulkan permasalahan ekonomi di wilayah perbatasan. Penelitian ini bertujuan untuk menganalisis hubungan jangka pendek dan jangka panjang serta melakukan peramalan penerimaan devisa dan jumlah wisatawan mancanegara di PLBN Entikong menggunakan pendekatan VECM. Data yang digunakan berupa data bulanan periode Januari 2018 hingga Desember 2024 yang mencakup penerimaan devisa dan jumlah wisatawan mancanegara. Analisis meliputi uji stasioneritas, penentuan lag optimum, dan uji kointegrasi untuk menentukan penerapan model VAR atau VECM, dilanjutkan analisis jangka panjang dan jangka pendek, uji diagnostik, IRF, VD, serta peramalan periode Januari 2025 hingga Desember 2029 dengan evaluasi menggunakan MAPE. Dalam jangka panjang, penerimaan devisa dan wisatawan mancanegara memiliki hubungan yang signifikan dengan arah pengaruh negatif, di mana peningkatan salah satu variabel pada periode sebelumnya menurunkan variabel lainnya. Dalam jangka pendek, kedua variabel tetap saling memengaruhi melalui mekanisme penyesuaian menuju keseimbangan jangka panjang, dengan wisatawan mancanegara berdampak positif terhadap penerimaan devisa, sedangkan penerimaan devisa berdampak negatif terhadap jumlah wisatawan mancanegara. Peramalan untuk periode Januari 2025 hingga Desember 2029 menunjukkan tren peningkatan yang stabil pada kedua variabel, dengan penerimaan devisa diproyeksikan mencapai sekitar 3,71 juta USD dan wisatawan mancanegara meningkat hingga 5.368 orang pada akhir periode. Akurasi peramalan untuk periode Januari 2025 hingga September 2025 tergolong cukup baik berdasarkan nilai MAPE sebesar 23,75% untuk penerimaan devisa dan 20,89% untuk wisatawan mancanegara.

Abstract

This Community Service Program (PKM) aimed to enhance data literacy and information visualization skills among Satu Data administrators of local government agencies (OPD) through Microsoft Power BI training at the West Kalimantan Provincial Communication and Information Agency (Diskominfo). The program was implemented through preparation, face-to-face training, and evaluation stages using pre-test and post-test instruments. The training covered fundamental concepts of data analysis, data visualization techniques, and hands-on dashboard development using regional sectoral data. The results of the paired sample t-test analysis indicated a statistically significant improvement between participants’ pre-test and post-test scores, demonstrating the effectiveness of the training. Furthermore, analysis using Partial Least Squares Structural Equation Modeling (PLS-SEM) revealed that training material quality had a positive and significant effect on participants’ learning outcomes, while other supporting factors such as training duration, facilitator performance, and technical aspects did not show significant effects. These findings highlight that well-structured and relevant training materials play a critical role in improving participants’ competencies. Overall, the program contributed to strengthening analytical skills and supporting the implementation of the Satu Data Indonesia policy toward transparent and evidence-based data governance

Abstract

This study examines the comparative performance of the Capital Asset Pricing Model (CAPM) and Arbitrage Pricing Theory (APT) in estimating expected stock returns within the IDX BUMN20 Index. The study is motivated by the ongoing debate regarding the empirical validity of single-factor and multifactor asset pricing models, particularly in emerging markets such as Indonesia. While prior studies provide mixed evidence, limited research has focused specifically on state-owned enterprise indices, which exhibit distinct risk characteristics. Using monthly stock price data, this study estimates expected returns under both models and evaluates their performance using Mean Absolute Deviation (MAD), which measures the average deviation between estimated and realized returns. In the APT framework, factor sensitivities are estimated using a multifactor regression approach, incorporating macroeconomic variables as systematic risk factors. This allows a more detailed assessment of how multiple sources of risk influence return estimation. The results indicate that the CAPM demonstrates relatively better estimation performance, as reflected by lower MAD values compared to the APT. However, the APT provides additional insights into the role of multiple risk factors, suggesting its relevance in capturing more complex market dynamics. These findings highlight that while simpler models may perform more consistently in certain contexts, multifactor approaches remain valuable for understanding broader sources of systematic risk. The study contributes to the asset pricing literature by providing empirical evidence from the IDX BUMN20 Index and offering a more nuanced comparison between single-factor and multifactor models in an emerging market setting.
