Mangroves on Bengkalis Island experienced a decline between 2000 and 2019. This decrease in mangrove forest area was caused by anthropogenic activities and natural factors, such as coastal erosion. The objective of this study is to assess the current condition of mangroves on Bengkalis Island, Riau, Indonesia. The research was conducted in March 2024 across four rivers on Bengkalis Island, with each river containing three research stations: upstream, midstream, and downstream. Data collection involved capturing aerial photos of mangroves using drones over 100 m x 100 m. The photos were analyzed using the supervised image classification method to identify and assess mangrove land cover. A total of 11 mangrove species were identified along the rivers. The most widely distributed species across all locations were Rhizophora apiculata and Xylocarpus granatum. Canopy cover at all research sites was classified as dense, with coverage exceeding 75%. This study provides crucial information about the condition of mangroves on Bengkalis Island, serving as a guideline for future restoration efforts.

The change of Minister of Education is often followed by new policies that cause various reactions among the public, including students and educators. This study aims to understand public perceptions of the change of Minister of Education and its implications for curriculum policy. This research uses a descriptive qualitative approach with a questionnaire-based interview data collection method to educators and students. The results showed that most respondents had positive expectations of the new minister, especially regarding improving the quality of education and reducing the administrative burden on teachers. However, there were concerns about repeated curriculum changes. Respondents emphasized the importance of inclusive communication, strengthening the role of teachers and improving education infrastructure. Active stakeholder support is considered essential in realizing relevant, effective and sustainable education policies.

This research aims to design and test a genset fuel conversion system from gasoline to HHO gas (brown gas) as a more environmentally friendly alternative. Conventional fossil-fueled generators face challenges in theform of limited resources and the impact of environmental pollution. In this study, HHO gas is produced through a water electrolysis process using an HHO generator that separates water molecules into hydrogen and oxygen using electric current. The test results show that increasing the voltage from 2.58 V to 5.12 V significantly increases the volume of gas produced. At a voltage of 2.58 V, the gas volume reached 110 ml, and increased to 750 ml at a voltage of 4.72 V. The generator set was successfully operated for 1 minute 15 seconds with HHO gas using a separate battery power source. These results demonstrate the potential of HHO gas as an efficient alternative fuel for generator sets. This study recommends further testing with voltage and current variations to find the optimal configuration, as well as the use of a larger power source to increase the efficiency of HHO gas electrolysis.

Configuring, managing, and programming IoT devices is essential in the digital age. By participating in this training, vocational school teachers in Kulon Progo can acquire practical skills directly applicable to their curriculum, helping students understand IoT concepts more deeply and practically. The IoT (Internet of Things) and Digital Transformation - Skill For All (SFA) training is designed to provide a comprehensive understanding of networking basics and how to configure and manage IoT Kits devices

This research aims to design and simulate a DC motor speed control system using integral state feedback (KISF) control. This control is designed to maintain DC motor speed stability with high accuracy despite disturbances or load changes. The research stages include mathematical modeling of the DC motor, PID control design, integral state feedback control design, simulation implementation and simulation results analysis. The show that althought integral state feedback control has a rise time 273.501 ms, slightly slower than PID 197.604 ms, integral state feedback compensates with higher slew rate of change 6.540 V/ms compared to PID
4.344 V/ms. Integral state feedback offers greater
flexibility through pole placement values with Ackerman’s formula J3 = [-12 -100 -600], indicating that this system has good capability in responding to input changes, thus maintaining motor speed stably and efficiently. This indicates that integral state feedback control is superior in system adaptation and handling complex dynamics.

The Constitutional Court is a judicial institution in Indonesia which was established on August 13, 2003. The Constitutional Court has the authority regulated in article 24C of the 1945 Constitution and Law Number 24 of 2003 concerning the Constitutional Court which was later updated to Law Number 8 of 2011. The Constitutional Court has a principle in making a decision on the material test of the law against the Constitution, which applies to everyone, final, independent and impartial. The Constitutional Court's (MK) decision regarding the age limit for presidential and vice presidential candidates (presidential and vice presidential candidates) in Case Number 90/PUU-XXI/2023 continues to reap pros and cons. In the decision, the Constitutional Court granted part of the application that tested Article 169 letter q of Law Number 7 of 2017 concerning General Elections. This study aims to identify and analyze disputes over the Constitutional Court Decision Number 90/PUU-XXI/2023 concerning the material test of article 169 letter q of Law number 7 of 2017 concerning general elections in terms of juridical aspects. The research method used is a literature study of the Constitutional Court decision Number 90/PUU-XXI/2023 with a focus on normative legal analysis. The results of the study show that the Constitutional Court's decision Number 90/PUU-XXI/2023 is formally inconsistent with Law Number 49 of 2009 concerning Judicial Power and Constitutional Court Regulation No. 2/PMK/2021.
