Judul: Penilaian Ekonomi dan Daya Dukung Wisata Bahari di Pulau Pari Kepulauan Seribu Provinsi DKI Jakarta
Abstrak: The economic assessment and carrying capacity of Pari island marine tourism in Thousand islands of DKI Jakarta province are intended to determine the land suitability of Pari island for the marine tourism, to estimate the physical carrying capacity of Pari island for the marine tourism, to estimate the economic values of Pari island for the marine tourism and the economic impacts for the local people. The analysis of tourism land suitability shows that the group of Pari island in accordance with the parameter of brightness and flow velocity is really appropriate with the parameter of the types of coral reefs and reef fish species, is appropriate with margin and is sufficiently appropriate with the live coral cover; and in accordance with the width parameter is of the potential for 361,5 ha diving and 939,55 ha snorkeling activities.

Judul: Analysis of Ecological, Social Conditions and Perceptions of Small Island Tourism: Case Study of Pari Island, DKI Jakarta
Abstrak: Indonesia adalah negara kepulauan dengan kurang lebih 16.771 pulau. Pulau Pari adalah pulau di bagian selatan dari perairan Kepulauan Seribu dengan jumlah wisatawan yang berkunjung pada tahun 2021 mencapai 30.531 orang. Penelitian ini bertujuan menilai kondisi ekologi dan sosial Pulau Pari sebagai pulau wisata dan menganalisis hubungan persepsi wisatawan terhadap kondisi lingkungan untuk wisata di pulau tersebut. Jenis data yang digunakan dalam penelitian ini adalah data primer dan sekunder. Data sekunder diperoleh untuk mengetahui kondisi ekologi dan sosial. Data primer diperoleh untuk mengetahui persepsi wisatawan. Data primer diperoleh dengan cara membagikan kuesioner kepada wisatawan. Hasil penelitian menunjukkan bahwa kondisi terumbu karang dan hutan mangrove yang berada di Pulau Pari mengalami penurunan setiap tahunnya sedangkan kondisi padang lamun di pulau tersebut menunjukkan hasil yang stabil. Nilai korelasi antara kepentingan aktivitas dan kepuasan wisatawan terhadap kondisi lingkungan menunjukkan korelasi positif yakni berturut-turut sebesar 0.845 dan 0.888. Hal tersebut berarti bahwa semakin tinggi kepentingan dan kepuasan wisatawan maka semakin tinggi kualitas lingkungan di Pulau Pari, ndonesia is the largest archipelago with approximately 16,771 islands. Pari Island is an island located in the southern part of the Thousand Islands waters with the number of tourists visiting the island in 2021 reaching 30,531 people. This study aims to assess the ecological and social conditions of Pari Island as a tourist island and analyze the relationship between tourist perceptions of environmental conditions for tourism on the island. The types of data used in this study are primary and secondary data. Secondary data were obtained to determine ecological and social conditions. Primary data were obtained to determine tourist perceptions. Primary data were obtained by distributing questionnaires to tourists. The results showed that the condition of coral reefs and mangrove forests located on Pari Island has decreased every year while the condition of seagrass beds on the island shows stable results. The correlation value between activity interests and tourist satisfaction with environmental conditions shows a positive correlation of 0.845 and 0.888, respectively. This means that the higher the importance and satisfaction of tourists, the higher the environmental quality on Pari Island

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.
