Abstract

Pada karya ilmiah ini, penyebaran influenza dua strain dimodelkan dengan melibatkan tiga variabel kontrol yaitu vaksinasi dan pengobatan pada masing-masing strain. Akan ditentukan variabel kontrol optimum sehingga dapat meminimumkan populasi terinfeksi berdasarkan empat skenario pengendalian. Prinsip maksimum Pontryagin diterapkan untuk menurunkan sistem persamaan diferensial sebagai kondisi yang harus dipenuhi variabel-variabel kontrol optimum. Kemudian, metode Runge-Kutta orde empat digunakan untuk menentukan solusi numerik dari masalah kontrol optimum. Pada solusi numerik ditunjukkan bahwa pemberian tiga buah kontrol pada model penyebaran influenza H1N1 dua strain memberikan pengaruh yang baik karena dapat menurunkan populasi individu terinfeksi oleh strain satu dan strain dua sampai 99% serta meningkatkan populasi individu yang telah diobati secara efektif sampai 85% pada bulan ke lima.

Abstract

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. This disease represents a significant global public health challenge. Consequently, a stochastic differential equation model of tuberculosis has been developed. In this context, an analysis examines the impact of complete treatment on the disease-free population distribution, duration of disease-free status, and the probability of remaining disease-free. The analysis shows that as the rate of complete treatment increases, the probability of achieving disease-free status rises, the duration of remaining disease-free shortens, and the number of disease-free individuals grows over time. Keywords: Complete Treatment, Disease-Free Duration, Stochastic Differential Equations, Tuberculosis

Abstract

Abstract. This study aims to analyze the effect of COVID-19 on banking resilience in Indonesia and to investigate whether there are differences in the effect of COVID-19 on Islamic and conventional banks. Using panel regression with robust standard error on 38 conventional banks and sharia banks going public in Indonesia, covering the period before the COVID-19 pandemic (Q3 2018-Q4 2019) and during the COVID-19 pandemic (Q1 2020 – Q2 2021), it shows that the existence of the covid-19 crisis has a significant effect on all bank financial performance indicators, but not significant on all bank risk indicators. Using the independent t-Test test with the assumption of unequal variance and Welch correction, this study conducts a comparative test based on six panels of criteria and found that Islamic banks are more resilient than conventional banks.Keywords: Resilience, Bank Financial Performance, Bank Risk, Covid-19 Abstrak. Penelitian ini bertujuan untuk menganalisis pengaruh COVID-19 terhadap resiliensi perbankan di Indonesia dan menginvestigasi apakah terdapat perbedaan pengaruh COVID-19 terhadap resiliensi bank syariah dan konvensional. Menggunakan regresi panel dengan Robust standard error pada 38 bank konvensional dan bank syariah yang sudah ‘go public’ di Indonesia, meliputi periode sebelum pandemi COVID-19 (Q3 2018-Q4 2019) dan selama pandemi COVID-19 ( Q1 2020 – Q2 2021), studi ini menunjukkan bahwa keberadaan krisis covid-19 berpengaruh signifikan terhadap semua indikator kinerja keuangan bank, dan tidak signifikan terhadap semua indikator risiko bank. Dengan menggunakan uji Independent t-Test dengan asumsi unequal variance dan Welch correction, penelitian ini melakukan uji komparatif berdasarkan enam panel kriteria dan diperoleh kesimpulan bahwa bank syariah lebih tangguh dibandingkan bank konvensional.Kata kunci: Ketahanan, Kinerja Bank, Risiko Bank, Covid-19

Abstract

This study examines how the Business Model Canvas (BMC) is applied in the Kyboks rice box business. Kyboks is a unique and affordable business that faces challenges due to its remote locations. The researchers utilized BMC as a tool to map Kyboks’ business model and expand its market coverage. The research method involved descriptive research with a qualitative approach, and data was collected through interviews with a Kyboks business owner. The analysis of the collected data using a qualitative approach and BMC revealed that Kyboks incorporates all nine elements of the BMC in its operations. Kyboks targets Gen-Z, individuals in specific areas, office employees, and spicy food enthusiasts. The value propositions offered by Kyboks include good chili flavor, affordable prices, unique rice box combinations, and free delivery. Kyboks employs social media platforms, particularly Instagram, and word of mouth as distribution channels. To further expand its business reach, Kyboks should explore creative and innovative ideas, such as collaborating with influencers.Keyword: Business Model Canvas, Rice Box, Kyboks, Business Analyst
