Abstract

Alternative energy sources and energy storage play an important role in maintaining and providing energy. The application of indoor photovoltaic is one alternative in energy management using artificial light sources. However, one of the main obstacles faced in the operation of photovoltaic panels is the significant problem of low electrical efficiency in photovoltaic cells. The purpose of this research is to find out the performance of indoor photovoltaic with variations of LED and CFL lamps with a capacity of 5W and 10W, as well as the variation of the given distance which is 25 cm and 30 cm. The research method used is to test the temperature sensor using the MAX 6675 sensor and the voltage and current sensor using the MAX471 sensor. The light intensity produced by the lamp is read by the sensor. The electricity produced by photovoltaic is stored in the battery. The results read by the sensors are displayed on the serial monitor. The results of the research show that increasing the distance between the lamp and the light field results in a decrease in light intensity. This can be seen in the CFL lamp with a longer distance between the light source and the solar cell module which results in the light intensity of the 5W 30 cm CFL lamp being low. The decrease in the efficiency of photovoltaic systems in the room has an effect on the temperature that the increase in photovoltaic temperature causes a decrease in the efficiency of the current and voltage of the electricity output.

Abstract

The most critical component of a motorcycle's combustion process is the spark plug, which fires sparks for the ignition system. In this research, the performance of several spark plug electrode gap diameters and materials was varied to detect how much they affected engine performance, fuel consumption, and emissions. Engine testing was conducted on a 110-cc four-stroke engine. Nickel material spark plugs with a gap dimension of 0.9 mm, platinum material spark plugs with a gap dimension of 0.8 mm, iridium material spark plugs with a gap dimension of 0.7 mm, and two types of ignition coils. The test findings indicated that there is a spark plug with an appropriate gap for engine performance in the form of torque and power in the B2 configuration, which has a gap of 0.8 mm. Increasing the spark plug gap produces a loss in engine performance, but it also increases it. There is an optimal point of fuel consumption in configuration B2, where raising the spark plug gap decreases fuel consumption while increasing the spark plug gap increases fuel consumption. Exhaust emissions likewise experience an optimal point in configuration B2, when exhaust emissions rise as long as the spark plug gap is increased once more, HC and CO levels decrease with an increasing spark plug gap. To examine the study on the impact of spark plugs with electrode gaps and ignition coils on engine performance, fuel consumption, and emissions. This can provide insight into a reference technique for using spark plugs and ignition coils.

Abstract

Abstrak Modul thermoelectric yang diaplikasikan pada kompor merupakan sebuah alternatif untuk menghasilkan listrik dari perbedaan suhu dengan prinsip seebeck, namun perbedaan bahan bakar pada kompor mempengaruhi luaran listrik yang dihasilkan. Penelitian ini bertujuan untuk menganalisa pengaruh penggunaan variasi bahan bakar terhadap performa modul thermoelectric dalam penerapan pada kompor untuk menghasilkan listrik. Penelitian ini dilakukan dengan menggunakan delapan modul thermoelectric tipe SP 1848 27145 SA yang diapit oleh aluminium setebal 8mm pada sisi panas dan water block pada sisi dingin, kemudian ditempelkan pada dinding kompor tungku. Percobaan dilakukan dengan membakar tiga jenis bahan bakar secara bergantian yaitu arang kayu asam, briket batok kelapa, dan batubara dengan berat yang sama yaitu 300 gram. Hasil penelitian menunjukkan bahwa arang kayu asam merupakan bahan bakar yang paling baik digunakan dengan luaran daya modul thermoelectric sebesar 8.91 W, diikuti oleh briket batok kelapa dengan luaran sebesar 1.04 W dan batubara sebesar 0.96 W.Kata Kunci : Modul Thermoelectric, Kompor Tungku, Bahan Bakar

Abstract

HHO gas is being developed as an alternative fuel due to its efficiency and clean emissions. Water electrolysis with electrolytes and effective electrodes is one production method. This study assessed the efficacy of the HHO gas generator concerning the quantity of electrode plates and varying electrolyte concentrations, specifically NaOH and KOH. The HHO gas production rate during electrolysis exhibited variations with electrolyte concentrations of 2%, 4%, 6%, 8%, and 10%. The configurations of the electrode plates utilized comprised two, four, and six stainless-steel plates. The experimental findings indicated that the KOH electrolyte continuously surpassed NaOH, particularly at elevated concentrations, where increased electrolyte levels significantly enhanced the HHO gas production rate. Optimal conditions were achieved by employing six electrode plates with a 10% potassium hydroxide solution, equivalent to 66.67 grams per 600 milliliters of distilled water, yielding a maximum gas generation rate of 6.9 ml/s. Moreover, hydrostatic pressure study indicated that elevated electrolyte concentration and an increased number of electrode plates directly correlated with enhanced gas production and pressure.

Abstract

Mild steel dampers are widely utilized as energy dissipation devices due to their ductility and stable mechanical behavior. This study presents a numerical investigation of the effects of plate thickness and material variation on the mechanical performance of an H-type mild steel damper using nonlinear finite element analysis. The model is developed in ANSYS with three-dimensional solid elements, incorporating material and geometric nonlinearity to capture structural response under loading. Two parametric studies are conducted, including plate thickness variations (15 mm, 20 mm, 25 mm, and 30 mm) and material variations (structural steel, grey cast iron, and aluminum alloy). The mechanical behavior is evaluated based on deformation, equivalent stress, and strain distribution along the damper height. The results show that increasing plate thickness significantly reduces deformation and strain while improving stress distribution, indicating enhanced structural stiffness. However, excessive thickness may limit deformation capacity. In terms of material performance, structural steel exhibits the most stable behavior with low deformation and controlled stress and strain distribution. Aluminum shows higher deformation and strain due to its lower stiffness, while grey cast iron demonstrates limited ductility and higher stress concentration. An optimal configuration is identified at a thickness of 20-25 mm using structural steel, providing a balance between stiffness and deformation capability. These findings contribute to the design optimization of metallic dampers for structural applications.
