One of the basic functions of drilling fluids is to transport drilled cuttings to the surface. Bentonite with low solids content is preferred in carrying out this task. However, a low amount of bentonite in the drilling mud is incapable of effective cuttings lifting and suspension. In this study, a new, green, low-cost henna leaf extract and lignite in bentonite water-based drilling mud was used to transport cuttings to the surface. The effects of three hole angles (0°, 45° and 90°) were examined at different cuttings size diameters (0.5 mm, 1.0 mm, 2.0 mm and 2.4 mm) for the mud systems. The average cuttings transport efficiencies were found to be in the following order: 52-94% for 0.5 mm diameter, 45-93% for 1.0 mm diameter, 38-90% for 2.0 mm diameter, and 33-83% for 2.4 mm diameter. Viscosity and hole angle are directly related to cuttings transport efficiency. A plastic viscosity of 16 cP and yield point of 12.5 lb/100ft² were the most effective mud properties for a 45° hole angle, which needs attention while preparing the drilling mud. Addition of henna and lignite can be used to improve the rheological and filtration properties of bentonite water-based drilling mud.

Fossil fuels contribute to global warming and climate change. Solar energy, a renewable and safe energy source, is a promising alternative. Solar thermal energy (STE) can be used in various sectors to produce thermal or electrical energy from the sun. In Malaysia, electricity is cheaper, making it less appealing to switch to renewable energy. This study aims to explore the potential of solar thermal heat systems in industrial processes in Malaysia, focusing on the oil palm refinery Mewaholeo Industries Sdn Bhd. The main challenge is the high capital investment and varying efficiencies of solar thermal systems, which depend on technical specifications and environmental factors. To determine the optimal specifications for solar thermal system installation, this study will examine the process flow, propose a solar thermal system design, collect data, and integrate solar thermal energy. The best collector type, number of collectors, and solar thermal design will be analyzed using an Excel tool called Solar Heat Industry Process (SHIP) for performance and financial evaluation.

Through a thorough analysis using Net Present Cost (NPC) over a 20-year period, this research presents a comprehensive and economically optimized solar panel design methodology. The study examines two different PV system configurations: On-Grid PV and Off-Grid PV, using sophisticated simulation and analytical techniques with the aid of HOMER Pro software. The simulation results offer compelling new information about these systems' economic viability. The simulation results in an NPC value of IDR 31,386,360,- for the Off-Grid PV configuration. The On-Grid PV system, in contrast, exhibits a significantly lower NPC value of IDR 8,903,329,- emphasizing its superior economic performance. This On-Grid PV system boasts a significant energy generation capacity of 5,012 kWh/year in addition to favorable cost efficiency. Notably, this is greater than the National Power Company's 1,186 kWh/year energy output. These results highlight the financial benefits of the On-Grid PV system and demonstrate its capability to provide affordable and sustainable energy solutions over a long period. The thorough analysis carried out in this study aids in the optimization of solar panel designs, offers insightful information for future sustainable energy projects, and emphasizes the crucial part that economic factors play in influencing the adoption of renewable energy technologies.

Using Python scripts over the MAVLink protocol, developers can use the open-source DroneKit Python software framework to enable autonomous drone operations. This framework provides excellent flexibility and power to facilitate automated drone control. The built quadcopter has an X configuration and uses a DJI F450 frame with some modifications. Interestingly, the drone has legs made of aluminum on both sides to help with smooth takeoffs and landings. The frame is 45 cm diagonal length and 30 cm vertical height. The drone was given an additional weight in a 15 x 18 x 12.5 cm box. The propeller used in this investigation is a 9x6 carbon-based model. The x2216 1400kV brushless motor that is being used is from Sunnysky, and it comes with an Electronic Speed Controller (ESC) with a 30A rating. A 4-cell 14.8V Lithium-Polymer (Li-Po) battery with a 7200mAh capacity powers the drone. Apart from that, the drone weighs 1573g in total. The results are obtained by self-measurement and flight measurement data (FMU). Six attempts were made, and the results showed that the second flight had the longest flight time and the highest altitude. In particular, the Flight Measurement Unit (FMU) reported that the flight lasted 81 seconds and reached an altitude of 0.93 meters. In contrast, the self-measurement data reported that the flight lasted 85 seconds and reached an altitude of 1.5 meters.

The hydroponic installation in the hydroponic community of Matur District, Agam Regency, West Sumatra, faces a major problem with a crop failure rate reaching 30%-35%. This issue is primarily caused by disruptions in nutrient flow due to the lack of continuous electricity, which affects pump operation. To address this problem, efforts are needed to ensure that the nutrient flow to the plants is maintained. The aim of this activity is to assist the hydroponic community in increasing plant production through the application of innovative technology. The solution implemented is the use of hybrid power generation system technology, integrating Solar Power Plants (PLTS) and PLN electricity. This system ensures that water pumps operate optimally, even at night or during bad weather. The implementation of this technology has been completed and directly tested. The pump is capable of delivering nutrients to all planting holes. The performance testing of the hybrid power generation system was conducted in the laboratory and at partner locations. The results of the system testing show that the voltage values meet the load requirements, with a voltage difference still within the tolerance range of 2.2% - 3.3%, thus not disrupting the motor's performance. The energy source switching time is <4 seconds, specifically 0.6 seconds from the solar power plant (PLTS) to the national grid (PLN) and 3.4 seconds in the opposite direction. This transition indicates that the hybrid power generation system operates efficiently, with pumps and lighting functioning well. Thus, it is expected that this system can significantly increase the productivity of hydroponic plants and boost the income of the hydroponic community.
