<![CDATA[Many people in general still use manual weight measurement, even though manual weight measurement cannot distinguish between fat mass and non-fat mass. Therefore, in this study, the authors created a tool that can measure body fat percentage using the Bioelectrical Impedance Analysis (BIA) method. The BIA method is a method of measuring body fat levels by sending an AC current at a certain frequency to the body. Then by measuring the voltage generated, it can be known the magnitude of the impedance value in the human body. In measuring fat, the authors chose the hand-to-hand method. Starting from generating an AC signal with a frequency of 50kHz by the Oscillator circuit, it is then processed by the Howland circuit so that the current sent to the body is constant with a value of 0.22mA. This tool uses a load cell sensor as a body weight detector and an ultrasonic sensor as a body height detector. By using these tools the user can determine the value of body weight and height as well as the percentage of body fat with an accuracy of up to 96.22% when compared to Omron products, whereas when compared to manual measurements without methods, the average accuracy value is 82.23%. From this comparison, it can be concluded that fat measurement using the BIA method is more accurate than manual fat measurement.]]>

<![CDATA[The management of abundant oil waste in companies that are spread over tin mining operational locations is still not optimal. The waste oil comes from engine oil and hydraulic oil. With proper management, waste oil will become useful and have added value. This waste can be processed into HSD (High Speed Diesel) fuel, so the company will get profit. The processing method used in waste treatment is the pyrolysis process. In this study, a pyrolysis tool was designed and built, and a test was carried out to obtain optimal parameters for the resulting fuel product using the Response Surface Methodology (RSM) method. The tests were carried out using activated Zeolite powder catalyst and 1000 ml of oil in each test. The indicators and parameters observed are the Quantity HSD and the percentage of Zeolite. The results of the optimization of the research process with the optimum formulation, namely setting temperature 285 oC, catalyst 109.8 gr, product yield 898.1 ml. Where as in the use of Raw Material Hydraulic Oil, the optimum formulation is a temperature of 325.8 oC, 118.6 gr catalyst, and a product yield of 920 ml with a duration of 60 minutes.]]>

<![CDATA[Based on the increasing need for electricity for the community, especially in the Bangka Belitung region, which still uses a lot of expensive fossil energy (generators), so it is still a cost constraint for people living in remote areas that have not been electrified. So it is necessary to innovate in making electricity that utilises natural resources (water). However, the problem is that water sources in some places have erratic water discharge. Therefore, in this research it is proposed to make a portable hydropower plant so that it can be moved in a place that has a high water discharge that can monitor the rpm, voltage and current of the generator and battery and is expected to be used as a cheap and environmentally friendly alternative power plant. The methodology in making this hydropower plant uses a 100Watt DC generator with a 12-bladed breadshot turbine type and is controlled using LM393 sensors and INA219 sensors with a monitoring system using the Blynk application by utilising IoT-based technology. The test was conducted by testing the effect of generator rpm speed on generator current and voltage, battery charging and discharging time, and testing the monitoring system using the Blynk application. From the test results, it is obtained that the minimum generator rpm that must be achieved when charging the battery is 425 rpm with the power obtained of 12.19Watt. Charging a 50 Ah capacity battery at the hydropower plant takes 6 hour and 38 minutes with a charging current of 6,7A. While for battery discharge using a 12V 75Watt lamp load takes 7 hours 25 minutes. The generator monitoring system using the Blynk application works well in displaying the same measurement results on the LCD screen with an accuracy value of 100%.]]>

<![CDATA[The use of plastic has become a common thing in different lives. The effect of using these plastic products is to create plastic waste. As the population increases, the accumulation of plastic waste will increase. So that it can be done by applying the 3R method, namely reduce, reuse, and recycle. Plastic waste is used as a lightweight brick reinforcement material. This study aimed to determine the factors that most influence the density value of cellular lightweight concrete with plastic filler and optimize the production process. The method used is the Response Surface Methodology (RSM). The experimental design was chosen Central Composite Design with three factors. The independent variables used in this study were the amount of plastic, the fraction of sand: cement, and the volume of water. The amount of plastic used is 2 grams, 3 grams, and 4 grams. The fraction of sand:cement was 4:3, 3.3:2, and 2:1. The volume of water used was 60 mL, 80 mL, and 100 mL. The results of this study indicate that the optimal value for the density of lightweight bricks is found in the amount of plastic of 7.745 grams, the fraction of sand:cement is 5.8:2, and the volume of water is 139.509 mL. The surface response from the second-order equation is the saddle point with the optimal point at the stationary point. The stationary points obtained are 2.821, 2.726, and 1.769. The research analysis results show that the independent variable that most influence the density value is the fraction of sand: cement.]]>

<![CDATA[Wood as the main raw material in making furniture causes the need for wood to increase while in its processing almost 30% of wood is wasted into waste just like that. In overcoming these problems, it is necessary to conduct research for the utilization of waste used for wood processing. Limited equipment in the manufacturing process becomes an obstacle to be one of the causes in the development of particle board products into a household industry. This research tried to make particle board with simple tools. This study used several parameters, namely 80:20, 70:30, 60:40, d and pressures of 7kg, 5kg, 3kg. The test results obtained the physical properties of wood dust composites with the Pva matrix, the lowest value was obtained at a variation of 80:20 pressure 7kg of 17.528% and the highest value at a variation of 60:40 pressure 7kg 117.237%. That the use of more matrices can inhibit water absorption is evidenced by micro photos at the 80:20 variation where the audience is no more than 25%. In the 60:40 variation, the use of more powder causes the glue bonding in this variation not to cover the powder as a whole like the 80:20 variation. Therefore, absorption at 60:40 is greater than at 80:20.]]>

<![CDATA[During this time animal fibers were often used only for textile products, from the mechanical properties of the Tarantula Web that were already known, the idea arose to utilize the Web Tarantula as a composite reinforcement. Composites will not form if they only use reinforcement, it is necessary to have a mixture of matrices so that the composite can blend perfectly. This study will use a Hollow Glass Microsphere (HGM) & Epoxy matrix. The printing process is carried out in layers, the first layer pours the homogeneous half of HGM-Epoxy on the mold until it covers the base of the mold, then assembles the weighed web into the mold, and finally pours back the remaining HGM-Epoxy until it fills the mold. The tested specimen data was then processed using Microsoft Excel to determine the effect of volume fraction on the impact strength of the Web Tarantula composite with HGM-Epoxy homogeneous matrix. The conclusion in this study is, Web Tarantula fillers 10%, 20%, and 30% do not greatly affect the homogeneous mechanical strength of HGM-Epoxy 20%/80% and 30%/70%, from six specimens with different volume fractions, after impact testing using the Charpy impact method, the five composites have the same value, only one specimen with Web 30%, HGM 30%, and Epoxy 70% has slightly different values. It can be concluded that the volume fraction of Web Tarantula, Homogeneous HGM-Epoxy does not add impact strength to the specimen made.]]>

<![CDATA[A high material removal rate is one of the goals to be achieved when machining parts with CNC turning. However, slow processing affects product processing time and increases production costs. To overcome this problem, it is necessary to set the correct process parameters so that they provide the most influential contribution to the MRR and produce maximum parameter values. This research aims to determine the influence of parameters (spindle speed, feed speed, and feed depth) on MRR and to determine the correct process parameter settings to produce maximum MRR, namely in this experimental design using an orthogonal array L9 (33) with three replications. The material used is ST-60 steel, with the data analyzed using the Taguchi Larger Is a Better method in analysis software. From the results of the mean factor calculation, the percent contribution to feeding was found to be 19.53%, while the depth of feeding was found to be 64.56%. The optimum MRR value is obtained from a combination of parameters in the CNC Turning process on ST-60 steel which can make the response value optimally obtained at the spindle speed 3,184 [rev/min], feeding 0.22 [mm/rev] and depth of cut 2.5 [mm].]]>

<![CDATA[The SWD 6TM410 diesel engine is a engine located in the Kayu Merah PLTD which has been operating for 37 years since 1982 with an installed power of 3380 kW. Currently, the SWD 6 TM410 engine can only operate with the operating power of the 2200 kW engine so that there has been a decrease in performance on the operational power that is quite significant from the installed force. The data analysis began with a recapitulation of operating journals, a review of machine overhaul reports, an analysis of factors affecting power loss and a calculation analysis of power loss factors for the operation of the SWD 6TM410 engine. The last breakdown was in 2016 due to a malfunction of the lube oil pump. The pressure and temperature of the lubricant are the limits to be taken into account when operating the SWD 6TM410 engine. The temperature and pressure values of the Lubricant have the highest presentation with the value of the 8.3% lubricating temperature and 7.2% lubrication pressure against a decrease in the power capable of operating SWD6TM410. There was a change of size on the crankshaft resulting in measurement values on crankpin 3 and 4 deflections passing the tolerance limit. It is necessary to make a material request for a new Lube Oil Cooler to replace the old Lube oil cooler so that the pressure and temperature of the lubricant on the engine can be optimal. Operating the SWD 6TM410 engine does not exceed the operational power limit so it does not result in fatal interference with the engine and makes the operating power of the SWD 6 TM410 machine increasingly decreasing.]]>

<![CDATA[Wood is the main substance commonly used in the particle board manufacturing industry. However, the rate of forest destruction that continues to occur makes the availability of wood decrease. Alternative materials to replace wood are needed. The salak frond, the object of this study, is a non-wood material that can manufacture particle board. This study used the full factorial method to see the effect of impact testing by comparing the use of polyester matrix and salak frond powder in particle board specimens. The parameters in this study used variations in oven temperatures of 800, 1000, and 1200 degrees Celsius for 15 minutes and volume ratios between salak frond powder and polyester matrix 80:20, 70:30, and 60:40. From the test results, the highest mechanical properties of impact strength were obtained at a ratio of 70:30 with a temperature variation of 1000 and an average of 15.80 kJ/m2. The lowest value is found in a ratio of 60:40 with a temperature variation of 800 and an average of 6.65 kJ/m2. The test results of this study have exceeded the standard impact strength of particle board on the market, which is 3.201 kJ/m2]]>
