Judul: Determinants of Islamic Bank Share Prices Fluctuation during the Covid-19 Pandemic (Case Study : PT. Bank BTPN Syariah).
Abstrak: Pandemi Covid-19 yang menyebar dengan cepat di Indonesia menyebabkan Pemerintah memberlakukan kebijakan penanggulangan kesehatan berupa Pembatasan Sosial Berskala Besar (PSBB) yang menyebabkan penurunan kinerja perekonomian nasional. Namun harga saham bank syariah khususnya saham PT. Bank Tabungan Pensiunan Negara Syariah (BTPS) tetap tumbuh bahkan melebihi kinerja IHSG. Oleh karena itu, guna mengetahui faktor-faktor apa saja yang memengaruhi harga saham BTPS baik itu faktor internal perusahaan maupun faktor eksternal perusahaan, maka penelitian ini dilakukan dengan metode VECM. Penelitian ini dilakukan dalam kurun waktu antara 2019-2020. Hasil penelitian menunjukan bahwa dalam jangka pendek, hanya variabel IHSG yang berpengaruh signifikan terhadap harga saham BTPS. Sementara pada jangka panjang, variabel Price ro Book Value, Trading Volume Activity, Produk Domestik Bruto, Suku Bunga Acuan Bank Indonesia, dan IHSG berpengaruh secara signifikan terhadap harga saham BTPS. Harga saham BTPS merespon negatif adanya guncangan PDB, Trading Volume Activity, dan Kurs. Sementara guncangan Earning Per Share, Price to Book Value, Suku Bunga Acuan Bank Indonesia, dan IHSG direspon positif oleh harga Saham BTPS. Price to Book Value memberikan kontribusi tertinggi dalam menjelaskan keragaman harga saham BTPS., The Covid-19 pandemic that spreads rapidly in Indonesia has caused the Government to impose a health management policy in the form of Large-Scale Social Restrictions (PSBB) which has caused a decline in the performance of the national economy. However, the share price of Islamic banks, especially BTPS shares, continued to grow and even exceeded the performance of the JCI. Therefore, using the VECM method, this research was conducted to find out what factors influence the stock price of BTPS, both internal and external factors of the company. This research was conducted between 2019-2020. The results showed that in the short term, only the JCI variable had a significant effect on the stock price of BTPS. While in the long term, the variables of PBV, TVA, GDP, Bank Indonesia Reference Rate, and JCI have a significant effect on BTPS stock price. The stock price of BTPS responded negatively to shocks in GDP, TVA, and the exchange rate. Meanwhile, the shocks of EPS, PBV, Bank Indonesia Reference Interest Rate, and JCI were responded positively by BTPS share price. PBV gives the highest contribution in explaining the diversity of BTPS stock prices.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol
