Increased doses of ethanol extract of Melophlus sarasinorum sponge increase the amount of macrophage phagocytosis activity that are 25,25% (negative control), 61,5% (positive control), 55,75% (100 mg/kg), 60,75% (200 mg/kg), 62,25% (300 mg/kg) dan 66,25% (400 mg/kg). The results showed that the ethanol extract of Melophlus sarasinorum sponge has the potential as immunomodulator at a doses of 300 mg/kgBB and 400 mg/kg with no significantly different effectiveness with positive control in increasing macrophage cell phagocytosis activity based on the result of post-hoc statistical test of Tukey (sig.> 0,05).
 
Evaluasi Konsumsi Air Beberapa Genotipe Padi untuk Potensi Efisiensi Penggunaan Air
Water use efficient varieties in rice may have good opportunity in term of economic value and scarcity of water. This study was conducted to determine water consumption among rice genotypes that conventionally cultivated as low land (IR64, IPB97-F-15, Ciherang, Mentik Wangi, and Rokan hybrid), up land (Jatiluhur, Silugonggo), and amphibian type (Way Apo Buru, that could be planted both as lowland and up land). Rice seedlings at 14 days old were transplanted in a plastic container containing 83 kg of air dried soil, 1 plant per whole and 6 plants per container. The experiment was conducted in a vinyl house, using randomized complete block design with three replications. During rice growth, water table was maintained at 2 cm above soil surface, and water was added and recorded weekly. The results showed that varieties reveal production components and yield were different significantly. Water consumptions among varieties were significantly different, ranged from 15.93 L plant-1 for IR64 to 24.13 L plant-1 for Jatiluhur, or equal with 3,639 to 4,827 m3 ha-1. Jatiluhur was the most efficient variety in using water. This finding may guide us to explore benefit of water use efficient variety as sustainable option in water management of rice cultivation
Analisis Pertumbuhan Investor Ritel Pada Masa Pandemi Dan Implikasi Pajak Penghasilan Final Atas Penjualan Saham Di Bursa
The Covid-19 pandemic has had a domino effect on the Indonesian economy and stock market. However, in the midst of a sluggish economy, there was a significant increase in the number of retail investors on the Indonesia Stock Exchange. This study aims to analyze the characteristics and level of tax compliance of retail investors who decide to invest in stocks during the pandemic, and to determine the impact of final income tax receipts on stock sales during the pandemic. The research method used is a qualitative method. The research was conducted using primary data and secondary data. Primary data used in the form of open questionnaire data to 120 retail investors. The secondary data used is data on final income tax receipts from the sale of shares from DJP, data on the volume and value of stock trading transactions from IDX, and investor demographic data from KSEI. The results showed that the majority of retail investors who decided to invest in stocks during the pandemic were under 30 years old, had a monthly income of less than IDR 4.8 million, and had a short-term investment type (trading). The level of tax compliance of retail investors who decide to invest in stocks during the pandemic has been formally good but still materially low. The Covid-19 pandemic had a positive impact on increasing final income tax receipts from the sale of shares on the stock exchange. This is due to a significant increase in the volume and value of stock trading transactions at the end of 2020 to early 2021 which shows a sense of investor optimism and is offset by an increase in the number of retail investors.Pandemi Covid-19 memiliki efek domino pada perekonomian dan pasar saham Indonesia.
