<![CDATA[Each mixture of fuel and gas has a different flame speed. Gas will only burn at a suitable percentage of air and produce different exhaust gas opacity, opacity is a ratio of the rate of light absorption by smoke expressed in units of percent. This study aims to theoretically analyze the relationship between the flammability limit and the variation of fuel which has a different setana number associated with the exhaust gas opacity value of the engine performance test equipment. The machine performance test equipment used is the L300 engine. The methodology used is the testing of exhaust gas opacity using the Koeng OP-201 opacity meter and theoretically analyzed its relationship with the bio solar, dexlite and pertamina dex flame limits. The results of this study found that bio solar has an upper flame limit of 6.65%, a lowerflame limit of 0.53%, and an average opacity value of 12.1%. Dexlite has an upper limit of 6.70%, a lower limit of 0.53%, and an average opacity value of 10.5%. Pertamina dex has an upper limit of 6.68%, a lower limit of 0.53%, and an average opacity value of 9.21%.]]>

The irregular placement of finished products in the storage can cause errors in the delivery of goods due to good management for delivering goods with a relatively fast time. The effort to overcome this problem is through designing of warehouse layout with the Class-Based Storage method. Grouping based on popularity. Stages of research carried out by calculating the warehouse, the frequency of displacement, the number of storage places, the displacement distance. Improvements begin by sorting material based on frequency and variations of three classes, namely A, B, C. To design the layout, information is needed when making a new storage layout. The results showed that the layout of the optimal results could reduce the displacement distance by 17.19% in 6 months and allow space to be 73.91%.]]>

<![CDATA[The motor releases torque and power to drive an electric car by carrying the load from a start position until it travels at the desired speed. The KMLI E-Falco electric car uses a BLDC type electric motor with a power capacity of 2 kW. To find out the amount of torque of a 2 kW BLDC motor when driving with variations in speed, it can be done by manual calculations using the torque equation and doing a dynotest test. The dynotest results show that the motor torque at the speed: 1 km/h is 1 Nm, 10 km/h is 131 Nm, 13 km/h is 228 Nm, 20 km/h is 225 Nm, 30 km/h is 219 Nm, 40 km / h is 188 Nm, 50 km / hour is 145 Nm, 60 km / h is 113 Nm, and 70 km / h is 85 Nm. From the results of the dynotest, it shows that the peak torque occurs at a speed of 13 km / h at 228 Nm. Racing software installed in the controller can increase the motor torque by four times at a speed variation of 13-70 km/h based on the results of the dynotest above. Keywords: motor, BLDC, torque, speed, acceleration.]]>

<![CDATA[High concentration of indoor air contaminant commonly released by human activities, furniture, building materials, carpets, cleaning product and paints. BTEX contains Benzene, Toluene, Ethylbenzene and Xylene (BTEX) is categorized into VOCs which are indicative of harmful chemicals especially for indoor air. Therefore, it needs the sampling media for absorption before it could be analyse in the specific laboratory. One of the challenging technology to absorb BTEX is by using Palm Shell Activated Carbon (PSAC). Malaysia has a second largest country that produce palm oil which led to abundant of palm shell as waste material. Activated carbon is created through the carbonization, crushing and activation process. Carbonization process is conducted in various holding time of 1, 2 and 3 hours which called by CT1. CT2 and CT3 hours, respectively. Activation process is conducted through physical activation at temperature of 900 0C for 1 hour, chemical activation is conducted by Potassium Hydroxide (KOH) with ratio of 1:1 (charcoal: chemical) and holding time for 12 hours. It heated by furnace at temperature of 850 0C for 1 hours in order to improve the porosity and larger surface area. The physical properties were conducted by ASTM 3713, 3714 and 3715 for moisture, as and volatile content measurement. Surface morphology and composition as well as porosity image is characterized by Scanning Electron Microscopy (SEM) coupled by Energy Dispersive Spectroscopy (EDS) machine. The result shows that the lowest ash, moisture and volatile content is shown by CT1 sample, but it has not completely carbonized as compared to CT2 and CT3. Moreover, CT3 has highest ash, moisture and volatile content but it has lowest fixed carbon as compared to CT1 and CT2. Therefore, CT2 hours is selected for further process. In microstructure analysis is observed that the PSACphysical+chemical has larger number of porosities with the diameter approximately of 50 to 150 µm, for PSACphysical approximately of 25 to 100 µm and PSACchemical of below than 50 µm. Composition analysis is observed that the sample is mainly consists of Carbon (C), Oxygen (O) and Potassium (K) content. Where larger porosity is in-line with the increment of K content which indicated in larger adsorption capacity. It can be summarized that palm shell with 2 hours carbonization time and it activated become PSACphysical+chemical has a high potential to larger adsorption capacity of indoor air contaminant adsorption. It is being further explore for sampling media of BTEX.]]>

<![CDATA[Abstract. Electric Submersible Pump (ESP) is an artificial lift method to lift fluid from the reservoir to the surface with a certain production rate, the ability of the pump to lift a certain fluid to the surface is adjusted to the capacity of the well itself. Over time, the production of oil wells will experience a decrease in the rate of production which will cause a decrease in pump performance. In several oil wells, well maintenance activities have been carried out. Therefore, in this study, an analysis of pump performance and optimization of the ESP pump was carried out using the Nodal Variable Speed Drive analysis method. The goal is to determine the production capacity of the oil well and determine the pump speed as desired. Oil well performance analysis and optimization of the ESP pump were carried out by mathematical calculations with the optimization results obtained that the DN1750 pump was installed at a frequency of 50 Hz, 55 Hz, 60 Hz, 65 Hz, and 70 Hz. The Hz number does not cross the desired flow rate line (q optimum) or is outside the desired fluid flow rate range by the oil well so it can be interpreted that based on the observation of the optimization process, the condition of the DN1750 pump is not working optimally so that the oil production capacity is not optimal. The DN 1800 pump at a frequency of 55 Hz with a speed of 3300 rpm is in accordance with the production capabilities of oil wells so that the appropriate pump is obtained and is expected to work at optimum conditions. At a frequency of 55 Hz with a speed of 3300 rpm successfully cut the desired flow rate line (q optimum) from the observed oil well characteristics or is in the range of fluid flow rates desired by the oil well, which is 1936,698 Barrels Per Day (BPD) with wellbore pressure (PWF) 629 psi. ]]>

<![CDATA[Activated carbon (AC) was recognized by many researchers as useful substance in adsorption of impurities. Several processes involved in the production of AC which were carbonization, crushing, and activation process. Carbonization of carbon required high temperature up to 900oC. Then the carbon will be crush to a desired size for activation process. Activation of carbon can be either chemical activation, physical activation or combination of chemical and physical activation which called physiochemical activation. The mechanism adsorption of AC commonly due to its micropore present in the carbon or the weak vander waals forces which can attract the impurities. Activated carbon have multiple function in human daily life. This study will be discuss the function of AC in the production face mask, water filtration and air filtration.]]>
