<![CDATA[The activity of dismantling shale sometimes does not align with the rating of the shale itself. Although shale generally has low durability, some types of shale exhibit considerable strength. Therefore, if the tools used are not suitable, the excavation process becomes inefficient. One shale classification method proposed by Franklin (1982) is by determining the value of slake durability index, plasticity index, and point load index. If the slake durability value exceeds 80 percent, testing continues with point load testing. However, if the slake durability value is below 80 percent, then liquid limit and plastic limit tests are conducted to obtain its plasticity index. This study is applied to the Kampungbaru Formation at PT Bintang Prima Energi Pratama. The shale testing results of the Kampung Baru Formation at PT Bintang Prima Energi yielded slake durability index values below 80 percent, thus the shale ratings based on slake durability index and plasticity index values, for KB1BL1 are 4.2; KB1BL2: 3.5; KB1BL3: 2.55; KB1BL4: 3.35; KB1BL5: 3.15; and KB1BL6: 3.65. With an average shale rating value of 3.57. The excavation tool used for these rocks is a backhoe.]]>

<![CDATA[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.]]>

<![CDATA[The use of automation systems is needed in sorting, one of which is the sorting of objects based on the size of the object being sorted. Especially in the sorting process, there are still many industries that use conveyors that only function for one product with the same weight characteristics. Therefore, to sort the same goods with different weights, a separate conveyor is needed so that many conveyors are used. The development of a sorting machine is an important aspect in the modern automation and manufacturing industry. This research aims to design and analyze the static loading of the sorting machine frame using SOLIDWORKS software. The design method used includes detailed 3D modeling of the machine frame by considering the strength, stability and reliability of the structure. The simulation results using SOLIDWORKS software show the stress (von Mises) with a maximum value of 82.26 MPa, while the theoretical calculation result is 84 MPa. Displacement with a maximum value of 4.063 mm, while the theoretical calculation result is 1.60 mm. The safety factor is 2.38, while the theoretical calculation result is 2.43. The difference between manual calculation and simulation is 0.02% for von Mises stress, 1.5% for displacement, and 0.02% for safety factor.]]>

<![CDATA[Uniaxial Compressive Strength is a test method to classify the strength and characterization of intact rock. Where it is important information in determining the strength and characteristics of a rock obtained by testing using the UCS tool. In this research, an alternative is made in determining the UCS value precisely and easily, namely by using the schmidt hammer test and compressive strength test. Therefore, this research aims to obtain the correlation value between the results of the compressive strength test and the schmidt hammer test on sandstone. Based on the results of observations and calculations that have been carried out, it can be concluded that the compressive strength value in the Balikpapan formation is lower than the compressive strength value in the Pulaubalang formation where the compressive strength value in the Balikpapan formation is 3.3 MPa-4.3 MPa, while the compressive strength value in the Pulaubalang formation is 4.3-5.57 MPa. The rebound number in the Balikpapan formation is lower than the rebound number in the Pulaubalang formation, where the rebound number in the Balikpapan formation is 16-17.8, while the rebound number in the Pulaubalang formation is 18-22.3. The correlation of the uniaxial compressive strength value with the rebound number of the schmidt hammer shows a positive linear correlation between the UCS value and the rebound number of the schmidt hammer, in this case it can be seen that when the uniaxial compressive strength value is higher, the rebound number of the schmidt hammer is also higher.]]>

<![CDATA[In simplifying the process of monitoring the temperature of electric vehicle batteries, especially in discharging conditions, a remote electric vehicle battery temperature monitoring system was created. The problem with the previous monitoring system was that there was no electric battery temperature monitoring system, so users could not monitor the temperature condition of the vehicle battery when in use. The purpose of this study is to design an Internet of Things (IoT)-based electric vehicle battery temperature monitoring device system using the web and add a data logger to monitor battery temperature remotely and find out the difference in temperature values from the device with a thermogun. And the addition of a cut off feature when the battery overheats as one of the safety. The research method uses experiments, namely by comparing the speed between 30km/h and 50km/h and comparing the readings of the monitoring device with a thermogun. In proving the performance of the monitoring equipment, it is carried out with a distance of 1km, 2km, and 3km and in sloping road conditions. The data obtained were then analyzed using the paired T-test method. The results of the study showed that the tool worked quite well with the highest error value of 3.88%. And the battery temperature value between the speed of 30km/h and 50km/h is a significant difference with a P-value result of 0.035 which means that H0 is rejected and H1 is accepted.]]>

<![CDATA[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%).]]>

<![CDATA[This research aims to analyze personality and communication styles in business negotiations. By examining various personality types such as extraverted, introverted, agreeable, conscientious, and neurotic, this study explores how personality characteristics influence communication strategies in the negotiation process. Through surveys and in-depth qualitative analysis of business professionals, the research found that individuals with extraverted personalities tend to be more proactive in taking initiative, whereas introverts are more inclined to deliberate carefully before acting. The communication styles employed also vary based on individual personalities. This research indicates that a deeper understanding of the role of personality in business communication can enhance negotiation effectiveness and improve final outcomes. The practical implications of these findings underscore the importance of adapting communication strategies based on the personality characteristics of negotiation participants to achieve success in dynamic and complex business environments.]]>
