Abstract

Abstract— EMRSA is a tool that can generate electrical energy by utilizing vibration energy that is wasted in a vehicle. Vibration energy includes energy that is wasted on vehicles and is still very rarely used. Therefore, in this study, an experiment was carried out to convert vibration energy into electrical energy. The purpose of this study was to determine the effect of the frequency of spring oscillations on the electric voltage produced by a laboratory-scale regenerative shock absorber. The research was carried out by providing variations in the load on the spring so that a different frequency was obtained in each experiment. The results of the experiment show that the frequency of the spring oscillation is directly proportional to the result of the electric voltage generated. The higher the frequency given, the greater the resultant voltage generated. From the experiments that have been carried out, the results of the electrical voltage of 0.537 volts are obtained at a frequency of 3.37 Hz with a number of copper coils of 500 turns and a copper diameter of 0.1 mm.

Abstract

Alat peredam kejut regeneratif elektromagnetik merupakan salah satu alat untuk mengonversi energi listrik yang didasarkan pada hukum Faraday. Mekanisme alat ini yakni dengan magnet yang bergerak dengan kumparan tetap, yaitu komponen utamanya menggunakan transduser induksi magnetik untuk membuat fluks magnet pada sebuah kumparan yang bergerak dalam medan magnet yang menyebabkan variasi fluks magnet melalui rangkaian listrik yang selanjutnya menghasilkan aliran listrik. Tujuan dari penelitian ini untuk memanfaatkan vibrasi pada peredam kejut dengan mengubahnya menjadi peredam kejut elektromagnetik dengan aplikasi skala laboratorium untuk mendapatkan energi listrik sebagai usaha menemukan sumber energi terbarukan serta mengetahui pengaruh variasi yang diberikan. Prosedur penelitian dilakukan dengan variasi diameter, jumlah lilitan tembaga dan frekuensi getaran yang tetap. Kumparan pada tembaga tidak bergerak, namun magnet N52 yang bergerak osilasi translasi melewati kumparan tembaga. Hasil penelitian memperlihatkan pengaruh variasi yang diberikan, yaitu semakin besar diameter tembaga yang digunakan maka tegangan listrik yang didapat akan semakin besar, sama halnya dengan semakin besar jumlah lilitan tembaga maka tegangan listrik yang didapat akan semakin besar. Adapun tegangan maksimal yang dapat dihasilkan yaitu 2,33 Volt yang didapat dari tembaga diameter 1 mm dengan jumlah lilitan 350.

Abstract

Conventional cooling systems used in office buildings are one of the causes of ozone layer depletion and greenhouse effects. It requires the advancement of new technologies that are safe for the environment to be used in cooling systems in office buildings. Absorption cooling systems using solar thermal energy have many advantages by using non-destructive working fluids such as water, or in the form of saline solutions. This is a form of energy saving and safe for the environment. In order to obtain real and objective measurement data, testing is performed in two stages, namely the test equipment testing stage and the second stage is data collection when the test equipment is fully operational. The test equipment can be used in stand-alone systems or conventional air conditioners. In the test, it is known that the average percentage of solar thermal energy consumption per day is 40% of total energy so due to solar thermal energy consumption, the average COP value of this system per day is 2 and this value is greater than similar absorption cooling systems. conventional, then by knowing the value of solar energy consumption, can be seen the value of CO2 emissions reduction of 143.8 kg CO2 per day.

Abstract

One of the basic competencies that Vocational High School (SMK) mechanical engineering teachers must have is being able to draw technically using CAD (Computer Aided Design) based applications. This competency is part of the competency field of study expertise that teachers must have. From the results of observations in the field, it was found that there are still many vocational school teachers in Cilegon City who are still not experts in using CAD-based applications, one of which is SMKS YP Fatahillah 1 Cilegon. As a form of implementation of one of the duties and obligations of the Tri Dharma of Higher Education, the Mechanical Engineering Department of Sultan Ageng Tirtayasa University carries out a community service program, namely training in the use of CAD-based technical drawing applications at SMKS YP Fatahillah 1 Cilegon. This activity was carried out for 3 days and was attended by 24 participants who work as teachers and laboratory assistants at the vocational school. The training method is delivered by lectures, presentations and direct exercises and practice. From this activity, the results showed that there was an increase in the competency of the participants, namely in their ability to draw techniques.

Abstract

The electric vehicle (EV) industries have grown; in 2023 EV sales increased by more than 30% compared to 2022. The central issue of this industry is the battery because of the cost and environmental problems.  This makes efficient battery operation and condition imperative. The electric vehicle lithium-ion batteries are highly temperature-dependent for optimal performance and longevity. A cooling system is needed to maintain the temperature of the lithium-ion battery within the optimal temperature range. This study proposes nanofluid cooling based on Cellulose Nanocrystals (CNC) inside the wavy channel tube. Other fluid cooling, such as air and water, are compared. Three-dimensional (3D) transient simulation is performed by varying the cooling fluid and mass flow rate. On the other hand, experiments were conducted to validate the simulation's conformity to the battery module's temperature. The performance of the cooling fluid inside the wavy channel effectively keeps the battery heat dissipation and temperature uniformity. The nanofluid can maintain the temperature of the battery module at its optimal temperature (below 40°C), even with the lowest flow rate (5×10-4 kg/s).

Abstract

Clean and healthy air are major topics around the globe. It is because poor air quality hurts human health and is even responsible for the deaths of millions of people. This work develops exhaust pipes containing filters to reduce the pollutants emitted by motorcycles. There are three pollutant concentrations measured here: CO2, CO, and HC. The measurements were taken before and after the filter system so that the pollutant reduction could be calculated.  The maximum pollutant reduction of the filter system: 6.1 % of CO2, 8.0 % of CO, and 651.0 ppm of HC. The primary mechanism of this filter is the physical trapping of pollutants. When the gas flows through the exhaust pipe, the pollutants in the stream are attached to the filter due to direct contact. This change can be visually observed in the filter color, which darkens after use in the exhaust pipe. However, a limitation of this work is its short-term experiment, which lasted only five minutes, indicating a key area for future research. It is also necessary to have alternative filters that are sustainable and can work properly in high-temperature conditions.

Abstract

Agriculture waste-based materials have considerable potential as wood-based particleboard alternatives. It has been produced abundantly from nature and considers an eco-friendly material. One of the enormous resources is the paddy by-product, rice straw (about 500 million tonnes per year worldwide). In this work, the mechanical properties of rice straw-based particleboard are predicted easily and quickly using the sessile drop method.  Rice straw was crushed into 2-5 mm diameter powder-like materials, and corn starch was used as the binder. The rice straw particleboard was formed under a hot press machine (5 MPa, 180°C and 120 minutes). Conventionally, the sample mechanical property was tested through Universal Testing Machine (UTM). Unfortunately, the process is costly and difficult to access. It is necessary to have a rapid and low-cost presumption of the mechanical particleboard properties toward more efficient manufacturing. This work proposes a simple sessile drop method to indicate particleboard mechanical properties. Multiple linear regression was performed to see the correlation between sessile drop and UTM testing. It was found statistically that the sessile drop method could be used as an early prediction of particleboard mechanical properties.
