Abstract

The three main factors determining combustion efficiency in Otto engines are optimal compression pressure, effective ignition, and fuel quality. In this study, two critical variables—fuel pump pressure (38, 43, and 48 Psi) and fuel type (RON 90 and RON 92)—were analyzed to understand their impact on specific fuel consumption (SFC). An experimental research method was employed to test the effect of independent variables on dependent variables under controlled conditions. The results indicate that a fuel pump pressure of 43 Psi provides the most stable and efficient fuel consumption performance for both fuel types across the entire engine speed range. A fuel pump pressure of 38 Psi is optimal at medium engine speeds but less efficient at high speeds, whereas a pressure of 48 Psi is most efficient at low to medium speeds but decreases in efficiency at high speeds. Overall, RON 92 fuel shows an efficiency improvement over RON 90, particularly at medium to high engine speeds. The combination of a fuel pump pressure of 43 Psi and the use of RON 92 fuel is recommended to achieve optimal specific fuel consumption, as it provides consistent efficiency across various engine operating conditions.

Abstract

The ignition system is an important system in a vehicle. Currently, the level of emissions produced by vehicles continues to increase every year. This can be caused by high fuel consumption values. The solution to this is to improve the quality of the spark plug by adding a capacitor to the ignition/ignition capacitor. The way the Plasma Capacitor Igniton works is by adding a high voltage non-polar capacitor which is connected in parallel to the output coil. The experimental method will be carried out using quantitative methods. By installing ignition plasma capacitors with different capacitor sizes of 1.5 mF (STD), 440 pF, 660 pF installed in parallel with the spark plug wires with variations in engine speed running from 1500 – 5500 rpm to check emissions. To check the fuel consumption value for Rpm 4500 - 9500 which has been adjusted previously. Fuel Consumption Test Results The use of 440 pF capacitors generally provides an increase in SFC efficiency at most engine speeds, with the largest percentage reduction at RPM 5500 (22.64%). The use of 660 pF capacitors shows varying results. At some RPMs, such as 5500, the SFC actually increases (3.77%), while at other RPMs such as 6500, it shows a significant decrease (27.66%).

Abstract

An increase in the number of vehicles should also be accompanied by improvements in technology that can increase engine efficiency and at the same time reduce air pollution. This research aims to determine the effect of using variations in the number of holes in the injector and the octane number of the fuel on exhaust emissions in motorcycle engines. The research method uses experiments with descriptive analysis. The independent variable is the number of holes in the injector, 4, 6, and 8 and the octane number of 90, and 92. In the exhaust emissions testing process using engine speeds of 1000 rpm, 2000 rpm and 3000 rpm. The bound variable is the emission of carbon monoxide (CO) gas and hydrocarbon gas (HC). Data from CO and HC gas emission testing results at 1000 rpm are all still within the permitted limits. Furthermore, statistical analysis shows that there is an influence of the number of holes in the injector and the octane value of the fuel on CO and HC exhaust emissions and there is no interaction between the octane value variables and the number of injector holes on the CO and HC exhaust gas values. The best results are CO gas emissions = 0.55% and HC = 66 ppm when using a 6 holes injector (standard) and using fuel with an octane value of 92.

Abstract

Spark plugs and ignition coils are important components in creating sparks in the combustion chamber. Sparks can be weakened by spark plug electrodes that are worn out due to time of use. Worn electrodes will cause the gap to increase, thus requiring a higher secondary voltage. This study aims to determine the effect of ignition coil resistance and spark plug thermal conductivity on 150 cm3 injection motorcycle power. The method used is an experimental method with a quantitative approach. The independent variables used in this study are ignition coil resistance with values of 3.0 Ω, 3.4 Ω, 3.8 Ω and spark plug thermal conductivity of nickel 90.9 W/m.K, platinum 71.6 W/m.K, and iridium 147 W/m.K.

Abstract

PD Andika adalah perusahaan yang menjual berbagai macam produk jadi, seperti alat tulis kantor, bahan pokok, kosmetik, makanan, minuman,obat, rokok, dan kebutuhan sehari-hari lainnya. Perusahaan ini memiliki gudang penyimpanan produk yang cukup luas dan terdiri dari 2 lantai. Akan tetapi, produk-produk yang ada di dalamnya tampak kurang tertata dengan rapi, dimana area gang ditempati oleh beberapa produk sehingga tidak dapat dilalui oleh trolley dan kategori produk yang sering dibeli oleh konsumen secara bersamaan diletakkan berjauhan. Hal tersebut dikarenakan penempatan produk dilakukan secara random, sehingga menyebabkan jarak pengambilan produk lebih jauh dan total waktu yang dibutuhkan menjadi lebih lama. Di samping itu juga terjadi masalah rusaknya dus kemasan produk akibat dimakan rayap, karena dus langsung diletakkan di atas lantai tanpa alas sehingga menyebabkan lembab. Metode yang diusulkan untuk memperbaiki tata letak saat ini adalah Dedicated Storage, dimana produk diletakkan pada tempat penyimpanan yangpasti dan tidak bercampur dengan barang lainnya. Metode ini juga dikaitkan dengan association rule mining untuk mencari korelasi antar kategori produk dan mengetahui kategori produk yang sering dibeli bersamaan oleh pelanggan. Manfaat penerapan tata letak usulan dari sisi kuantitatif adalah total jarak perpindahan produk yang semula sebesar 5.436,671 m per 6 bulan berkurang menjadi 1.231,788 m atau terjadi penghematan sebesar 4.204,883m atau 77,34 %. Dari sisi kualitatif, pengambilan produk menjadi lebih mudah karena digunakannya alat material handling berupa trolley barang serta produk sudah memiliki tempat penyimpanan yang pasti sehingga memudahkan dalam penyimpanan dan pengambilan produk-produk yang dibutuhkan. Dalam upaya menghindari gangguan rayap akibatlembabnya kardus kemasan produk, diusulkan penggunaan alas berupa kardus berukuran 90 x 90 cm dengan ketebalan 2 cm yang dimilikiperusahaan. Kata Kunci : association rule mining, dedicated storage policy, jarak perpindahan, tata letak

Abstract

Engine overheating is a critical condition that can cause damage to internal components, reduce operational efficiency, and lead to overall system failure. The absence of an automatic protection system is one of the primary factors contributing to damage. This study aims to design and test a temperature sensor-based safety device that can automatically cut off the engine's working system when the temperature exceeds the safe limit. The method used is descriptive statistical analysis to evaluate the effect of independent variables (operational time duration and workload) on the dependent variable (coolant temperature). The system was tested through water heating simulation using an electric heater and controlled by an Arduino Nano microcontroller, a MAX6675 temperature sensor. Testing was carried out with variations in power load (150, 300, 450, 600, and 750 Watts) and operational duration (20, 40, and 60 minutes). Temperature data were collected and analyzed using ANOVA to determine the effect of load and time on temperature increase. The results showed that the temperature increased significantly with increasing power load, with temperatures approaching 100°C at loads ≥450 Watts in less than 20 minutes. The load variable shows a significant effect on temperature (p < 0.05), while the duration of time shows a nonlinear but not statistically significant upward trend. The safety device is proven to be able to automatically disconnect the system when the temperature reaches the specified maximum limit, thus effectively preventing engine damage due to overheating.

Abstract

The rise in motor vehicle theft cases in various regions indicates the weakness of the security systems implemented by most users. Systems such as manual locks and alarms often fail to prevent crime, either because they are easily hacked conventionally or due to user negligence in their operation. In today's technological era, a system is needed that is not only secure, but also intelligent and practical. One promising solution is the implementation of a facial recognition-based security system. This study aims to design and test a vehicle security simulation system using facial recognition technology integrated with Arduino Uno and MATLAB. This system utilizes a laptop camera to capture the user's facial image, then performs a detection and verification process using the FaceNet algorithm. If the face is recognized and verified with data stored in the database, the Arduino will activate the actuator components in the form of a DC motor to simulate starting the engine, and a servo motor to simulate opening the vehicle door. This study uses a quantitative experimental approach to analyze the effect of variations in distance (30, 40, and 50 cm) and lighting brightness levels (10–20, 21–30, and 31–40 lux) on the system's response time. A total of 27 combinations of conditions were tested, and the data obtained were analyzed using Microsoft Excel and ANOVA tests in Minitab software. The results of the analysis showed that the optimal response time was obtained at a distance of 40 cm with a medium level of illumination (21–30 lux). In addition, both distance, brightness, and the interaction between the two factors were shown to have a significant effect on the system's response time (P-Value < 0.05). These findings indicate that the system is quite sensitive to environmental changes, so further testing is highly recommended, especially to measure the actual delay, the detection error rate, and the development of a more robust face detection algorithm so that the system can be used reliably in various lighting conditions and face capture angles in the real world.
