Abstract

Penelitian ini bertujuan untuk mengembangkan dan menganalisis performa prototipe pembangkit listrik hybrid berbasis energi matahari dan angin skala kecil yang dirancang untuk aplikasi rumah tangga. Sistem ini mengintegrasikan panel surya dan turbin angin melalui pengatur pengisian daya menuju satu sistem penyimpanan baterai, sehingga mampu mempertahankan kontinuitas suplai energi listrik pada kondisi cuaca bervariasi. Pengujian dilakukan secara eksperimental dengan mengukur arus, tegangan, intensitas iradiasi, dan kecepatan angin selama periode harian. Hasil penelitian menunjukkan bahwa daya maksimum sistem surya mencapai 20,32 W pada pukul 12.00 dengan intensitas iradiasi 776 W/m², sedangkan turbin angin menghasilkan daya maksimum 3,41 W pada kecepatan angin 2,6 m/s. Efisiensi konversi energi panel surya berkisar antara 2,40–2,62%, sedangkan efisiensi turbin angin relatif stabil pada 30–34%. Analisis regresi linear menunjukkan hubungan yang sangat kuat antara intensitas iradiasi dan daya keluaran (R² = 0,9867; r = 0,9933) serta antara kecepatan angin dan daya keluaran (R² = 0,9883; r = 0,9941). Hasil ini mengindikasikan bahwa kedua sistem memiliki performa yang konsisten dan responsif terhadap perubahan kondisi lingkungan. Sistem hybrid yang dikembangkan mampu memanfaatkan keunggulan komplementer dari masing-masing sumber energi, menghasilkan suplai daya yang lebih stabil dan berkelanjutan. Penelitian ini menegaskan potensi implementasi sistem hybrid surya–angin untuk mendukung elektrifikasi mandiri di daerah dengan intensitas radiasi tinggi dan kecepatan angin sedang.

Abstract

Limited electricity supply in crop storage buildings in Indragiri Village necessitates a simple alternative energy system that is suitable for local irrigation flow conditions. With a discharge of 0.006 m³/s and a head of 0.7 m, this study designed a picohydro power generation system through an engineering design approach that included energy requirement analysis, turbine component calculations, and mechanical design. The Pelton turbine was selected due to its optimal performance at low flow rates and its easy-to-maintain construction. The design results indicate a theoretical power of 28 Watts. The main components include a galvanized hollow frame measuring 850 × 500 × 350 mm, a runner with a diameter of 457.2 mm, a shaft with a diameter of 26 mm, blades measuring 150 × 100 × 50 mm, and pulleys measuring 304.8 mm and 50.8 mm. Materials such as chrome steel, resin, and aluminum were selected to ensure mechanical strength and corrosion resistance. This picohydro system is considered suitable as a small-scale alternative energy source for lighting and light electronic devices in agricultural facilities, and has the potential to be applied as a sustainable energy solution in Indragiri Village.

Abstract

Front bumper accessories are widely used to enhance vehicle protection; however, most designs are solely for aesthetics and basic protection. Most existing designs still make only a limited contribution to impact energy absorption in low-speed crash conditions. This study proposes a front bumper accessory that enhances impact energy absorption via a controlled deformation mechanism. A numerical simulation approach based on explicit dynamic finite element analysis is used to evaluate the impact performance of the proposed design in low-speed frontal crash conditions. The modified bumper system is compared with the base bumper configuration using parameters of absorbed impact energy, maximum impact force, and deformation behaviour. The research results show that the proposed bumper accessory increases impact energy absorption and reduces the maximum impact force compared to the base bumper system. The results of the feasibility study, considering the additional mass, ease of manufacture, and compatibility with existing bumper geometry, indicate that this accessory can be implemented as an additional component without requiring significant structural modifications. These findings indicate that bumper accessories with energy-absorbing features have the potential to improve low-speed crash performance in automotive applications.

Abstract

This study investigates a slider system used to transfer a CNC-manufactured crankshaft to the next production stage through dynamic simulation prior to motor installation. The simulation aims to determine the velocity, acceleration, and displacement of the slider under the influence of the crankshaft mass and applied torque in order to select a suitable driving motor. The research begins with the design and fabrication of the slider, followed by the definition of design parameters, including torque variations of 100, 130, and 150 N·mm, a travel length of 1 m, a crankshaft mass of 7.8 kg, and gravitational acceleration of 9.81 m/s². The dynamic simulation is performed by applying rotational input to the wheel, defining contact interactions between the wheel and the rail, and assembling the wheel with the rail track. The results show that among the three torque variations, the highest velocity and acceleration occur at a torque of 100 N·mm, yielding a velocity of 174.9 mm/s, an acceleration of 22 mm/s², and a reaction force of 1.47 × 10³ N, resulting in a travel time of 11 s to cover a 1-meter track.

Abstract

Ponds are one of the most popular cultivation methods in Indonesia. The Ministry of Maritime Affairs and Fisheries (KKP) recorded an increase in the value of fishery exports of 10.66% in the January – November 2022 period compared to the previous year. To increase fishery harvest yields requires the use of technology, one of the problems is regarding water quality, a decrease in water quality can disrupt fishery harvest results. The aim of this research is to create an Android application for monitoring water level, pH and temperature which was developed to help fish farmers monitor the condition of their ponds. The research method used is by conducting literature studies and interviews, then developing previous research by adding a pH sensor, GSM module, and updating the application display as well as optimizing PI control for water level control, then taking data from the sensor reading results compared with existing measuring instruments. tested to determine the level of accuracy and the information system data is taken on the average time required to send data to the application. The research results obtained are that the information system and water level monitoring for a prototype robot to control water levels in ponds has been developed by adding a GSM module as an alternative. replacement for the Wifi network with an average data transmission time of 3.6 seconds and implementation of PI control in the water level control system. Detecting water pH levels on a prototype robot that controls water levels in ponds has been successfully created and implemented with an average reading error of 2.15%. The water temperature reading on the prototype robot that controls water levels in ponds has been successfully optimized so that it has an average temperature reading error of 1.69%.
