Abstrak: Covid-19 berdampak pada berbagai kegiatan ekonomi di Indonesia salah satunya sektor pariwisata. Pantai Pasir Putih Wates merupakan salah satu wisata yang terdampak Covid-19. Penerapan protokol kesehatan dilaksanakan guna membatasi jumlah pengunjung sesuai daya dukung kawasan wisata. Tujuan dari penelitian ini; (1) menganalisis dampak lingkungan dan ekonomi wisata Pantai Pasir Putih Wates akibat Covid-19, (2) menghitung daya dukung kawasan sesuai protokol kesehatan di kawasan wisata Pantai Pasir Putih Wates, (3) menganalisis strategi pengelolaan wisata Pantai Pasir Putih Wates pasca pandemi. Metode yang digunakan yaitu SNI 19-3964-1994 untuk perhitungan timbulan sampah, multiplier effect, analisis daya dukung fisik (PCC), serta Analytical Hierarchy Process. Hasil penelitian menunjukkan bahwa terjadi pengurangan jumlah sampah yang dihasilkan dari aktivitas wisata selama pandemi. Setelah terjadi pandemi, keynesian income multiplier mengalami penurunan (2%), sedangkan ratio income multiplier tipe I dan II mengalami kenaikan masing-masing sebesar 7% dan 9%. Daya dukung kawasan wisata sebelum pandemi pada weekday, weekend, hari libur, hari raya idul fitri, natal, dan tahun baru berada pada under carrying capacity. Saat pandemi pada weekday, weekend, dan hari libur berada pada under carrying capacity, namun pada hari raya idul fitri, natal, dan tahun baru berada pada over carrying capacity. Prioritas strategi pengelolaan wisata pasca pandemi adalah peningkatan sarana dan prasarana., The Covid-19 in Indonesia affected various economic activities in Indonesia, including tourism.

The methods used are SNI 19-3964-1994 to estimate waste generation, multiplier effect to calculate economic impact, physical carrying capacity (PCC), as well as Analytical Hierarchy Process. Based on the result, the amount of tourism waste are reduced during pandemic. During pandemic condition, multiplier is decreased (2%), while the ratio of type I- and II-income multipliers is increased by 7% and 9% respectively. Tourism activity in Pasir Putih Wates Beach before the pandemic is under carrying capacity.

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
