Judul: Analisis Pengaruh  Pemahaman dan Kepedulian Mahasiswa IPB Terhadap Penanganan Pandemi
Abstrak: Pandemi Covid-19 telah menyebar ke seluruh dunia, tak terkecuali Indonesia. Berdasarkan data yang dirilis World Health Organization (WHO) per Agustus 2021 lebih dari 3 juta orang di Indonesia dinyatakan positif Covid-19 dengan lebih dari 120.000 orang dinyatakan meninggal. Berbagai upaya dan kebijakan telah dilakukan oleh pemerintah dan instansi terkait dalam penanganan pandemi. Upaya ini bertujuan untuk meningkatkan kesadaran dan juga menyebarluaskan langkah-langkah untuk mencegah penyebaran. Penelitian ini dilakukan dengan populasi yaitu mahasiswa strata satu IPB University dengan menggunakan cluster random sampling untuk mengukur tingkat pemahaman dan kepedulian terhadap Covid-19 terhadap kepuasan dan kepercayaan dari otoritas dalam menangani pandemi. Dengan menggunakan metode Partial Least Square-Structural Equation Modeling (PLS-SEM), model yang dihasilkan untuk kepuasan mahasiswa memiliki R2 sebesar 3,9% dan Q2 sebesar 3,2%. Faktor yang paling berpengaruh terhadap kepuasan mahasiswa adalah pemahaman mengenai tindakan penanganan dan pencegahan. Sedangkan model yang dihasilkan untuk kepercayaan terhadap instansi memiliki R2 sebesar 34,5% dan Q2 sebesar 25,1%. Faktor yang paling memengaruhi kepercayaan terhadap instansi adalah kepuasan mahasiswa., The Covid-19 pandemic has spread throughout the world, including Indonesia. Based on data released by the World Health Organization (WHO) as of August 2021, more than 3 million people in Indonesia have tested positive for Covid-19 with more than 120,000 people declared dead. Various efforts and policies have been carried out by the government and related agencies in handling the pandemic. These efforts aim to raise awareness and also disseminate measures to prevent the spread. This research was conducted with a population of undergraduate students at IPB University using cluster random sampling to measure understanding level and awareness for Covid-19 for satisfaction and trust from the authorities in dealing with the pandemic. By using the Partial Least Square-Structural Equation Modeling (PLS-SEM) method, the resulting model for student satisfaction has R2 of 3.9% and Q2 of 3.2%. The most influential factor on student satisfaction is understanding of handling and prevention measures. While the resulting model for trust in agencies has R2 of 34.5% and Q2 of 25.1%. The factor that most influences trust in the institution is student satisfaction

Judul: Satisfaction Levels of IPB Undergraduate Students towards Online Learning Services during the Pandemic Covid-19
Abstrak: Pandemi Covid-19 menyebabkan proses belajar mengajar di seluruh lembaga pendidikan harus diubah metodenya menjadi daring. Institut Pertanian Bogor (IPB) merupakan salah satu universitas yang ikut menerapkan pembelajaran daring terhitung dari bulan Maret 2020. Penelitian ini dilakukan dengan tujuan untuk menganalisis tingkat kepuasan mahasiswa S-1 IPB terhadap layanan pembelajaran daring selama pandemi Covid-19. Responden pada penelitian ini dipilih dengan menggunakan teknik voluntary sampling dengan jumlah responden sebanyak 255 responden. Data dikumpulkan melalui kuesioner online menggunakan google form. Data yang diperoleh diolah menggunakan microsoft excel, SPSS versi 25, dan SMART-PLS 3. Hasil analisis uji pengaruh menunjukkan kualitas layanan berpengaruh positif signifikan terhadap kepuasan konsumen, dan kepuasan konsumen berpengaruh positif signifikan terhadap net benefit. Saran yang bisa diberikan adalah IPB, dosen, hingga tendik departemen perlu mempertahankan dan meningkatkan kualitas pelayanan pembelajaran daring dari berbagai aspek., The Covid-19 pandemic has led to changes to the learning system online in all educational institutions. IPB University is one of the universities that implements online learning starting in March 2020. This research was conducted with the aim of analyze the level of satisfaction of IPB undergraduate students with online learning services during the Pandemic Covid-19. Respondents in this research were selected by voluntary sampling technique with 255 respondents. Data was collected through an online questionnaire using google form. The data obtained were processed using Microsoft Excel, SPSS version 25, and SMART-PLS 3. The results of the test analysis show that service quality has a significant positive effect on customer satisfaction, and also show that consumer satisfaction has a significant positive effect on the net benefit. Suggestions that can be given are that IPB, lecturers, and departments need to maintain and improve the quality of online learning services from various aspects.

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.
