There are several sources of Regional Own-Source Revenue (PAD) in accordance with Law number 1 of 2022, one of which is parking fees that falls under local fees. To optimize and enhance the Regional Own-Source Revenue (PAD), professional and transparent management of parking fees is necessary. This study aims to determine the design of an information system, its effectiveness, and the advantages and disadvantages of using an electronic parking system for paying parking fees in Indragiri Hilir Regency. This research falls within the realm of qualitative research. The data sources used in this study include primary and secondary data. Data was collected through interviews, observations, documentation, and literature review. Data analysis techniques employed encompass data collection, data reduction, data presentation, verification, and conclusions. The management of parking fees still encounters several obstacles, including a lack of field supervision, exploitation by irresponsible individuals taking advantage of negligence for personal gain, and incomplete allocation of parking revenue to local governments. One solution to address leakages in the management of parking fee funds is the implementation of electronic parking, enabling effective monitoring of all parking-related aspects, thereby contributing to an increase in Regional Own-Source Revenue from the local fee sector, specifically parking fees.

Nowadays, the use of solar energy is incredibly important to be increased since solar energy is renewable energy and also does not cause pollution. To harness solar energy, a solar collector device is needed to convert solar energy into heat energy. This study aimed to analyze the heat transfer in the flat plate solar collector which is used as a source of thermal energy in the water heating process for bathing. A double-glazed solar collector was used to absorb solar thermal energy and then transferred it to a water pipe. The pipe material used copper which has a very high conductivity value with an outer diameter of 15.7 mm. The plate collector used aluminium plates because they have high thermal conductivity. The dimensions of the collector frame were 150 cm long, 80 cm wide and 80 cm high. The collector frame was made of wood and covered with an insulator from coconut fibre with a thickness of 8 cm, with a tilt angle of 15˚. Based on the experimental process, the collector temperature was taken by using a thermocouple in order to heat the water which the inlet temperature in a bucket was 28˚C and the outlet water temperature during the experiment was 40˚C.

This study analyzes the impact of cooling load on condenser performance in the Steam Power Plant. The condenser, as a heat exchanger, plays a critical role in condensing steam from the turbine back into liquid form, thus maintaining the continuous cycle of the steam power system. Survey-based research was conducted, with data collected on steam and cooling water temperatures at various stages. The steam inlet and outlet temperatures were recorded at 514°C and 465°C, respectively, with cooling water entering at 32.9°C and exiting at 38.9°C at a flow rate of 100 m³/h. Using the Log Mean Temperature Difference method, initial and final temperature differences were calculated at 453°C and 465°C. Results suggest that tube fouling or leakage contributes to declining condenser efficiency, which can significantly reduce power plant performance. This study highlights the importance of regular maintenance and monitoring of condenser units to optimize thermal efficiency and power generation output.

This study was triggered by the existing teaching modules for the Shielded Metal Arc Welding (SMAW) subjects taught at vocational high schools, which do not align with the Freedom to Learn-Independent Campus (FLIC) learning objectives, and do not provide a systematic organization. In order to enhance the learning experience, this research developed a new learning module that integrated Problem-based Learning (PBL), promoting critical thinking, and the practical application of theoretical concepts, following the FLIC curriculum. Utilizing a Research and Development (R&D) approach with the Instructional Design Institute (IDI) model, this study involved two welding instructors and four lecturers as validators to assess the content and usability of the module. The IDI model comprised three steps: instructional (define), development (develop), and institute (evaluate). The research findings regarding the validity assessment by subject matter experts yielded a final validity score of 0.924, while media and language experts provided a score of 0.936, meeting the valid criteria. The practical usability test of the learning module resulted in a score of 94%, indicating that it is highly practical for students to use as learning media. Based on the validity and practicality assessments of the developed module, it can be concluded that the SMAW learning module is highly practical to use as teaching media, aligning with FLIC curriculum.

Air conditioning is not only important for the comfort of occupants in a building but also for various industrial processes. In the air conditioning process, a device called an Air Conditioner (AC) is required. The AC load can originate from inside the room and from outside the room. This study aims to determine the influence of increased cooling load from outside the room on the distribution of temperature and air humidity inside the conditioned room. The method used in this study involved conditioning four rooms. Two rooms of almost the same size were equipped with two AC units each, while the other two rooms used one AC unit each. Temperature and air humidity data inside the rooms were recorded every 20 minutes, as well as the outside air temperature. Dry bulb thermometer (Tdb) and wet bulb thermometer (Twb) were used to record temperature and humidity data, along with an environmeter. The research data were processed using available equations and with the assistance of a psychrometric chart. The research findings revealed that the average distribution of temperature and air humidity in the meeting room and office headroom of the Pertamina DP-LPG Office in Binjai was 20°C-23°C and 59%-65%. For the distribution office and sales service room of the Pertamina Fuel Filling Terminal in Kisaran, the distribution of temperature and air humidity was 25°C-29°C and 62%-66%. From the test results, it can be concluded that the distribution of temperature and air humidity is highly influenced by the capacity of the AC units and the cooling load entering the room.
