Protection of Financial Services Authority for Issuer Companies that will be Force Delisting by the Stock Exchange According to OJK Regulation No. 23/Po.Jk.04/2021
No full textThe Financial Services Authority (OJK) has important role to avoid being an subject to force
delisting by the stock exchange. This happens because issuers and stock exchanges are
subject to OJK. Therefore, it is necessary to know the delisting regulations by the stock
exchange in Indonesia, to know the protection of the Financial Services Authority for issuer
companies that will be force delisting by the stock exchange according to OJK Regulation
No. 23/POJK.04/2021.
This research is a normative legal or normative juridical research and uses analytical
descriptive. This research will examine the Protection Of The Financial Services Authority
For Issuer Companies That Will Be Forced Delisting By The Stock Exchange According To
OJK Regulation No. 23/POJK.04/2021.
The regulation of delisting by the stock exchange in Indonesia refers to the Decree of the
Board of Directors of the Indonesia Stock Exchange No. Kep- 00054/BE1/05-2024
concerning Regulation Number I-N. In its implementation, this regulation cannot be
separated from OJK Regulation No. 3/POJK.04/2021 concerning the Implementation Of
Activities in the Capital Market. Both regulations were born as special regulations so that
they are subject to the principle of lex specialis derogat legi generalis. The Financial
Services Authority's protection of issuer companies that will be forced delisting by the stock
exchange according to OJK Regulation No. 23/POJK.04/2021, refers to the principles of
Good Corporate Governance contained in Law No. 40 of 2007 concerning Limited Liability
Companies SO that shareholders, directors and commissioners can have their rights
protected when the issuer is subject to force delisting. The operation of issuers on the stock
exchange aims to ensure that the principles of Good Corporate Governance can run well.
Therefore, OJK plays a role in providing guidance in the form of of-site supervision,
technical inspections of compliance inspections and other supervisory actions as stated in
Article 3 of OJK Regulation No. 23/POJK.04/2021. The issuer's civil liability to investors in
the event of a force delisting by the stock exchange depends on the losses incurred as a result
of the actions of the directors or commissioners in managing the issuer or the issuer
company. It is expected that the government and legislature will draft new rules related to
delisting in the form of laws or government regulations or amend the capital market law by
including delisting regulations in it. It is expected that the government will make changes
tothe existing regulations so that there is no legal vacuum that contains legal protection for
issuer companies that will be forced delisted, not only limited to containing procedures and
reasons for force delisting. It is expected that the government will also make changes to the
regulations by including regulations related tocivil liability that arises due to force delisting
on issuers.141 PagesTesis Magiste

Design and Comparative Analysis of the Efficiency of Savonius and H-Darrieus Rotor Type Wind Turbines
No full textWind energy is one of the potential renewable energy sources to reduce
dependence on fossil fuels, but choosing the right type of wind turbine is still a
challenge to optimize energy conversion. This study compares the efficiency of
Savonius and H-Darrieus rotor type wind turbines under different wind speed
conditions to determine the best performance in each scenario. The research was
conducted using the experimental method through design, testing, and data
analysis with wind speed variations from 2 m/s to 6 m/s. The test results show that
at low wind speeds (2-3 m/s), the Savonius turbine is more efficient with an
output voltage of 3.6 V at 2 m/s and 8.6 V at 3 m/s, while the H-Darrieus turbine
only produces output voltages of 3.5 V and 5 V at the same speed. However, at
higher wind speeds (5-6 m/s), the H-Darrieus turbine showed performance with an
efficiency of 2.7% and a maximum torque of 88.17 Nm compared to the Savonius
turbine achieved an efficiency of 0.98% and a torque of 18.9 Nm. The Savonius
turbine is more suitable for low wind conditions, while the H-Darrieus turbine is
more optimal for high wind speeds, so its selection must be adjusted to the
environmental conditions.57 PagesSkripsi Sarjan
