Judul: Factors that Influence Sharia Banking Financing in the Agricultural Sector During the Covid-19 Pandemic
Abstrak: Sektor pertanian memiliki peranan yang sangat strategis dalam pengembangan ekonomi di Indonesia. Sektor pertanian merupakan salah satu sektor dengan kontribusi positif terhadap PDB selama Pandemi Covid-19. Namun, proporsi pembiayaan sektor pertanian pada perbankan syariah masih lebih rendah dibandingkan dengan sektor lainnya. Oleh karena itu, penelitian ini bertujuan untuk menganalisis faktor-faktor apa saja yang memengaruhi pembiayaan sektor pertanian pada perbankan syariah di Indonesia selama Pandemi Covid-19 dengan menggunakan metode VAR/VECM. Periode yang digunakan pada penelitian ini adalah Januari 2020 hingga Desember 2022. Hasil penelitian menunjukkan bahwa variabel DPK, FDR, BOPO dan PDB berpengaruh positif terhadap pembiayaan pertanian, sedangkan variabel NPF, Inflasi, dan PUAS berpengaruh negatif terhadap pembiayaan pertanian., The agricultural sector has a very strategic role in economic development in Indonesia. The agricultural sector is one of the sectors that contributed positively to GDP during the Covid-19 Pandemic. However, the proportion of agricultural sector financing towards sharia banking is still lower compared to other sectors. Therefore, this research aims to analyze the factors that influence agricultural sector financing in sharia banking in Indonesia during the Covid-19 pandemic using the VAR/VECM method. The period used in this research is January 2020 to December 2022. The research results show that the DPK, FDR, BOPO and GDP affect agricultural financing positively, while the NPF, Inflation and PUAS affect agricultural financing negatively.

Judul: Faktor-Faktor yang Memengaruhi Non Performing Financing Sektor Pertanian pada Perbankan Syariah di Indonesia
Abstrak: Kontribusi sektor pertanian terhadap Produk Domestik Bruto (PDB) Indonesia menunjukkan persentase kedua tertinggi. Namun, rasio pembiayaan bermasalah atau Non Performing Financing (NPF) sektor pertanian pada perbankan syariah selama tahun 2015 hingga 2020 menunjukkan tingkat rasio NPF yang tinggi, serta peningkatan NPF yang signifikan. Tujuan dari penelitian ini adalah menganalisis faktor-faktor yang memengaruhi NPF sektor pertanian pada perbankan syariah di Indonesia. Faktor-faktor yang diteliti meliputi faktor eksternal dan faktor internal. Metode yang digunakan yaitu Vector Error Correction Model (VECM) dengan data bulanan dari Januari 2015 hingga Desember 2020. Berdasarkan hasil analisis VECM menunjukkan bahwa dalam jangka panjang PDB pertanian berpengaruh negatif signifikan terhadap NPF sektor pertanian, sedangkan pembiayaan pertanian dan Kualitas Aktiva Produktif (KAP) berpengaruh positif signifikan terhadap NPF sektor pertanian. Analisis impulse response function menunjukkan bahwa guncangan inflasi, kurs, pembiayaan pertanian, dan KAP direspon positif oleh NPF sektor pertanian. Sedangkan guncangan PDB pertanian direspon negatif oleh NPF sektor pertanian., The contribution of the agricultural sector to Indonesia's Gross Domestic Product (GDP) shows the second highest percentage. However, the non-performing financing (NPF) ratio of the agricultural sector in Islamic banking during 2015 to 2020 shows a high level of NPF ratio, as well as a significant increase in NPF. The purpose of this study is to analyze the factors that influence the NPF of the agricultural sector in Islamic banking in Indonesia. The factors studied include external factors and internal factors. The method used is the Vector Error Correction Model (VECM) with monthly data from January 2015 to December 2020. Based on the results of the VECM analysis, it shows that in the long term agricultural GDP has a significant negative effect on the NPF of the agricultural sector, while agricultural financing and Productive Asset Quality (KAP) significant positive effect on the NPF of the agricultural sector. Impulse response function analysis shows that inflation, exchange rate, agricultural financing, and KAP shocks are responded positively by the NPF of the agricultural sector. Meanwhile, the agricultural GDP shocks responded negatively by the NPF of the agricultural sector.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
