"Penelitian ini bertujuan untuk menganalisis pengaruh skor ESG tinggi yang dimiliki perusahaan terhadap performa saham perusahaan yang tercatat pada Bursa Efek Indonesia saat pandemi Covid-19 tepatnya sejak kasus Covid-19 muncul di Indonesia pada tanggal 2 Maret 2020 hingga akhir pandemi Covid-19 pada 21 Juni 2023. Performa saham yang diukur pada penelitian ini terdiri dari imbal hasil saham dan volatilitas imbal hasil saham perusahaan terbuka sebanyak 77 perusahaan yang dijadikan sampel dalam penelitian ini. Jenis data yang digunakan bersifat cross-section dan time series sehingga pengelolaannya menggunakan salah satu teknik dari regresi panel data yaitu random effect model. Hasil dari penelitian ini menunjukkan bahwa terdapat pengaruh negatif antara skor ESG tinggi yang dimiliki perusahaan terhadap volatilitas imbal hasil saham perusahaan, tetapi tidak terdapat pengaruh antara skor ESG tinggi yang dimiliki perusahaan terhadap imbal hasil saham perusahaan yang tercatat pada Bursa Efek Indonesia saat pandemi Covid-19.

This study aims to analyze the effect of the company's high ESG score on the stock performance of companies listed on the Indonesia Stock Exchange during the Covid-19 pandemic, precisely since the Covid-19 case appeared in Indonesia on 2 March 2020 until the end of the Covid-19 pandemic on 21 June 2023. The stock performance measured in this study consists of stock returns and volatility of stock returns of 77 listed companies as a sample in this study. The type of data used is a cross-section and time series, so the method used is a technique of panel data regression, namely the random effect model. The results of this study indicate that there is a negative influence between the high ESG score owned by the company on the volatility of the company's stock returns, but there is no influence between the high ESG score owned by the company on the stock returns of companies listed on the Indonesia Stock Exchange during the Covid-19 pandemic."

"Heart is one of the most vital organs in human body. Without it, blood is impossible to be transferred to a 11 body. Nowadays, there are many factors that can cause heart fail, and the cases of heart fails are increasing. In some of these cases, the heart is permanently fails, so that the replacement or support for the heart is needed. While the heart donors is lagging behind the rate needed, then Total Artificial Heart is needed.Development of TAH has grown rapidly, so many TAH product are in market. Some of them have already implanted in human body.The original pump developed by Hoang Tran (1996) was used as based to which this scaled up pump was modeled after. The rig testing that was used by Daniel Timms was used as the starting point to develop the new rig.The new rig was designed with better features the rig before. Measurement devices, especially for head pressure was improved by using electronic pressure transducer. This new rig was not using motor from Daniel Timms Rig, DC motor that is safer and easy to control was used. To control this Motor, power supply with variable voltage option was used.Pump Characteristic Graph was measured by the pump performance testing. From this testing, the efficiency from this pump and system can be measured based on the voltage and current that was used by motor."

"Penelitian ini membahas masalah konsensus pada sistem multi-agent dengan model setiap agen adalah nonholonomic mobile robot dengan pengendali finite-time yang terdistribusi pada setiap agen. Setiap agen harus mengikuti kecepatan referensi yang telah dibuat dan state setiap agen harus mencapai konsensus dalam waktu yang terbatas. Masalah lain yang dibahas adalah keberadaannya disturbance atau gangguan dari luar sistem. Pengendali finite-time digunakan untuk memecahkan kedua masalah ini karena pengendali finite-time dapat memberikan waktu konsensus pada waktu yang terbatas dan dapat mengatasi keberadaan gangguan dari luar sistem. Pengendali finite-time juga dapat dilinierisasi dengan mengubah parameter pengendalinya. Selain masalah pengendali konsensus, penelitian mengenai perbandingan sistem dengan multi-agent dan sistem tanpa multi-agent juga dilakukan. Berdasarkan simulasi yang dilakukan, terlihat bahwa sistem dapat mencapai konsensus dalam waktu yang terbatas. Saat sistem diberi disturbance, terlihat juga bahwa sistem tetap dapat mencapai konsensus dalam waktu terbatas. Sistem multi-agent juga memberikan waktu konsensus yang lebih cepat dibandingkan dengan sistem tanpa multi-agent.

In this study, we discuss the consensus problem of nonholonomic mobil robot multi-agent systems with distributed finite-time control for each agent. All the agents have to follow the reference velocity and reach a consensus in a finite-time. The other problem discussed in this study is the presence of disturbance. Finite-time controller is used to solve the above problem because of its reliability. Linearized finite-time control is also shown by changing the control parameters.

One last problem discussed is the comparison between system with multi-agent and system without multi-agent. Based on simulation results, it is shown that multi-agent system can reach consensus in a finite time. In the presence of disturbance, it is shown that the systems still can reach consensus in a finite time. System with multi-agent also reach consensus faster than system without multi-agent."
